9 Claims, 3 Drawing Figures MODULAR MAUSOLEUM CRYPT SYSTEM BACKGROUND OF THE INVENTION l. Field of the Invention This invention relates to an improved. above-ground. multi-level mausoleum construction. More particularly. the invention relates to a mausoleum construction comprising a plurality of tiered. interlocking. pre cast modules. which, when assembled. yields a substantially monolithic structure with improved stability and rigidity characteristics and which is capable of withstanding external forces without damage.

2. Description of the Prior Art In recent years there has been increasing emphasis placed on the efficient utilization ofland. especially for burial purposes. in areas where the population growth has been significant. One particular pressing problem which has received attention for at least the past two decades is the use of above-ground mausoleums. similar in concept to highrise apartments. The advantages of above-ground. multi-level mausoleums are readily seen since this concept permits a more efficient utilization of land and has the added advantage of permitting visitors to be indoors while paying respects to the deceased. where lobby-like facilities are provided.

Heretofore. a variety of construction techniques have been employed to construct multi-level. above-ground mausoleums. One such technique utilizes the pouredin-place" technique used in apartment construction. Thus. concrete is poured in forms on the site. level by level. until the entire structure is completed. In this manner. a multi-story mausoleum can be fabricated according to design. This approach yields a highly satisfactory product but is economically undesirable-by virtue of the slot and relatively expensive fabrication technique employed.

In an effort to reduce costs. attempts have been made to utilize precast sections for one or more portions of the mausoleum structure. One such approach is described in U.S. Pat. No. 2.525.017 (issued on Oct. 20. 1950) which describes a mausoleum formed of precast sections comprising a unitary open-ended crypt unit which can apparently be positioned in spaced relationship. the space between units forming another cavity which can also be separately enclosed. Although the precast units are generally rigid. nevertheless the cavity portions between the precast units require an undue amount of effort to ready them for crypt use. More over. the assembled structure described in U.S. Pat. No. 2.525.017 does not possess the required rigidity and stability necessary to resist external forces.

Another technique which utilizes precast sections for mausoleum construction is disclosed in U.S. Pat. No. 3.287.865 (issued on Nov. 29. 1966). Here a tiered structure made of abutting precast sections is described. On its face. this construction appears to avoid the difficulties noted in U.S. Pat. No. 2.525.0l7. However. a careful analysis of this construction reveals that the horizontal and vertical joints formed by the abutting walls of adjacent sections are in an aligned orientation. Since the alignment plane is vertical. extending from the lowermost tier to the uppermost tier. it is clear that this represents a cleavage plane which can cause serious problems when subjected to external stress. Moreover. the alignment plane is substantially equidistant between adjacent vertical walls, and therefore has little. if any. underlying support.

Up until the present invention. there still existed a need for an improved mausoleum construction combining the structural qualities of the poured-in-place construction with the desirable attributes of precast sections.

OBJECTS AND SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a mausoleum construction which is substantially comparable in performance to poured-in-place construction but without the associated drawback of high cost and lengthy construction time.

It is another object of the present invention to provide an improved mausoleum construction. of the char acter aforementioned. comprising precast concrete modules adapted to horizontally and vertically interlock with one another when placed in side-byside relationship. to form a substantially monolithic structure capable of resisting external stresses without cracking and the like.

It is still another object of the present invention to provide an improved mausoleum construction. of the character aforementioned. wherein the precast modules are provided with upright side walls merging at their upper portion at a horizontal slab. and at their rear wall portion at a rear wall, the front and bottom portions of the module being open permitting internesting during transport thereof.

These and other objects are accomplished by providing a mausoleum construction comprising a plurality of tiered crypts formed from modular. monolithic. precast concrete modules. each of the tiers including a left end. intermediate. and right end module. positioned in horizontal side-by-side abutting relationship with next adjacent sections. and interlocking with one another to form unitary structure. after assembly. The intermediate modular section includes an upper. horizontally disposed slab. a pair of spaced vertical or upstanding side walls having respective longitudinal axes and depending from the horizontal slab. and a rear wall. The spacing between the upstanding side walls is of a predetermined width. preferably uniform. to form a crypt cavity. The horizontal slab includes one edge terminating adjacent one of the upstanding side walls forming a ledge therein, and an opposite edge projecting beyond the longitudinal axis of the next adjacent upstanding side wall for a predetermined distance. in cantilevered fashion. A rear wall is provided which extends substantially from the longitudinal axis of one of the vertical walls to beyond the free edge of the cantilevered horizontal slab portion. Ledges are provided in the next adjacent module for receiving the free edges of both the cantilevered portions of the horizontal slab and the projecting portions of the rear wall for interlocking purposes.

For reasons which become more apparent hereinafter. it should be emphasized that the inventive concepts ofthe improved mausoleum construction of the present invention do not reside in the particular number of tiers and/or crypts. as illustrated in the drawing. but can be varied to accommodate the number of crypts desired for any particular installation. Moreover. although each tier is illustrated to be identical with respect to the modular unit employed therein. when compared to the remaining tiers. this arrangement can also be varied such that left and right end modular units of adjacent tiers can be different to further displace the nonaligned horizontal and vertical joints formed by the interloclting modules. In other words. in one tier. the left end modular unit can include a single crypt. whereas in the overlying tier. the left end modular section can be larger. e.g.. two crypts. this arrangement being repeated. depending on the number of tiers provided. A similar alternating arrangement can be provided at the right end modular section of each tier. This nonsymmetrical construction provides additional structural rigidity and stability for only a slight increase in overall erection expense.

lt shoud also be mentioned that each of the upstanding side and rear walls of each modular unit tapers downwardly so as to be received and grouted in grooves provided in the upper surface of the modular unit positioned in the tier directly below. Each modular unit is in a secured position during assembly to effect proper alignment of the sections. A non-shrinking grout is employed to form fluid-tight joints for interengaging units.

From the aforementioned. and the description which follows. it will become apparent that the mausoleum construction of the present invention offers considerable structural and cost advantages over prior techniques. When completed. the mausoleum construction of the present invention is a substantially monolithic structure which is self-supporting. No additional supporting walls are required. further reducing construction costs. Construction versatility is another feature of the present invention, with as few as three crypts to twenty thousand or more crypts per installation. erected. The precast concrete modular units can be readily fabricated in a plant under carefully controlled conditions and shipped to the construction site for assembly. using a minimum of skilled labor. structurally. the mausoleum construction of the present invention has a high degree of stability by virtue of non-aligned. interlocking lap joints. It has been demonstrated that the mausoleum construction of the present invention is capable of withstanding external forces, e.g.. high wind loadings. climatic changes. and the like, without damage to its fluid-tight joints. By such improved construction the egress of odors emanating from within the crypt. as well as the entry of rain water and the like. is precluded.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a pictorial representation of an illustrative embodiment ofa mausoleum construction according to the present invention. with portions removed to show certain internal features.

FIG. 2 is a pictorial representation of a modular unit in interlocking relationship with a next adjacent modular unit shown in phantom. with particular emphasis on the horizontally and vertically disposed lap joints at the abutting upper and rear walls.

FIG. 3 is a pictorial illustration. in exploded view. of the preferred modular units employed in forming a single tier of the mausoleum construction of the present invention. with alternative right end modular units being shown.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to the drawings wherein like numerals indicate like elements throughout the several views. there is shown an above-ground or garden-type mausoleum construction according to the present invention. The mausoleum construction of the present invention. as shown in perspective in FIG. I, is a four tier structure. each tier represented by the symbols I. II. III and IV. from bottom to top. respectively. The four tier mausoleum is supported by aconcrete base 10. Each of the tiers. l-IV. includes a plurality of assembled precast modular units. preferably of reinforced concrete. permanently bonded to each other by cement to form a unitary structure. For purposes ofclarity. the precast modular units employed for one or more crypts are best seen in the exploded view of FIG. 3 where the letters A. B. C. D are used for each different type of unit. These modular units are exemplary of the inventive concepts described herein. and can be readily modified to expand or reduce the number of crypts per tier. In FIG. 3, module A is a left end unit. module B an intermediate or central unit. modules C and D are alternative right end units. Generally. each tier includes. in side-by-side relation, at least a left end modular unit A. an intermediate modular unit B. and either right end modular unit C or D. depending on whether an odd or even number of crypts per tier are desired.

Again. for purposes of clarity. only the intermediate modular unit B will be fully described, it being understood that the other modular units include substantially identical features. except where otherwise noted. As best seen in FIGS. 2 and 3, the intermediate modular unit B includes a pair of spaced. upstanding side walls 11. 12. the spacing between the side walls being of predetermined width. to form acrypt cavity 13. Modular unit B further includes an upper. horizontally disposedslab 14 which is integrally formed withside walls 11 and 12. Theupper slab 14 extends laterally beyond the side wall 11 in cantilevered fashion with the cantilevered portion being identified as I5, and terminates at afree edge 16. In the exploded view. FIG. 3. either of the right end modular units C or D can be used. as represented by the broken arrows. depending on whether an odd or even number of crypts per tier is desired. In either case. a ledge 17 is provided on modular units C and D to receive the cantileveredslab portion 15 forming a lap joint I8 having horizontal and vertical components 18a. 18b. respectively.

Intermediate modular unit B also is provided with an integrally formedrear wall 20 which extends laterally from the longitudinal axis of theside wall 12 to beyond the free edge I6 of the cantilevered portion I5 of thehorizontal slab 14 coveringcavity 13 and cavity 13' and terminates at afree edge 21.Rear wall 20 extends vertically from the bottom of the side walls II and 12 to thetop surface 22 of the upper slabs l4 and 15. The rear wallfree edge 21 forms a lap joint 24 with the vertically extending ledge 25 (see FIG. 2) formed in the rear wall portion of the next adjacent right end modular units C and D. The lap joint 24 has a transverse and vertical component 24a. 24b. respectively. which provides interlocking means for the portion of the rear wall extending beyond theterminal edge 16 of the upper slab I4. The interlocking distance is shown in FIG. 2 as X and is equal to the distance between theterminal edge 16 of the upper slab I4 and the longitudinal axis ofside wall 12. Although not shown. the intermediate modular unit B also includes asimilar ledge 25 at itsrear wall 20 running vertically from the longitudinal axis of theupstanding wall 12 to the left for receiving the projectingrear wall portion 21 of left end modular unit A therein.

An important feature of the present invention resides in the fact that the horizontally disposed lap joint 18 between abuttinghorizontal slabs 22. and the verticallydisposed lap joints 24 between adjacent rear walls are in non-aligned orientation in three planes. By such a construction, cracks which may appear along any of the joints are isolated and will not be transmitted to the other joints due to the discontinuous nature of the various joints involved.

The side walls ll. 12 are generally tapered with their lowermost portion being narrower than theintermediate portion 30 or their enlarged portion or haunch 3!. Thehaunch 31 is integrally formed with the upper slab l4 and includes anchor means (not shown) for securing brackets 32 (see FIG. 2) for reasons which will become more apparent hereinafter. The enlarged portion orhaunch 31 of the side walls 11. 12 provides the necessary support for the cantilevered portion of the next adjacentupper slab 14. Additionally.haunch 31 provides the necessary mass to receive and hold anchor bolts therein. Each of the end portions of modular units A. C. D includes an outermost side wall ll. which does not include ledges 17. therein. Moreover. since side wall ll is substantially planar and constitutes the outer wall of the assembled mausoleum. it can be left unfinished or can be finished with an appropriate decorative facingmaterial 35. as shown in FIG. I.

The upper slab M of modular unit B includesgrooves 36 formed along the front and rear edges of the slab l4, and extending adjacent the free edge l6 of cantileveredportion 15. Essentially. thegroove 36 is of a width and spacing so as to securingly receive the side walls ll, 12 of superposed modular unit B to form a next tier. Preferably. each of therear walls 20 is tapered similarly to the side walls ll, 12 to fit thegroove 36. Similar grooves are also provided in the base 10 to secure side and rear walls of the first tier l of modular units A-C or D.

In FlG. l the assembly is shown withcrypts 13 both in open and sealed condition. For sealing purposes each crypt is formed with arecess 40 at its entry. extending the entire perimeter, including the top surface of the crypt directly below. A sealing or closure plate 4], preferably of an asbestos-cementitious material. e.g.. Transite (a product of .lohns-Manville Company, Mansville. NJ.) is fitted within therecess 40 after a casket is placed in thecrypt 13, thereby completing the entombment of the deceased. Any conventionally known suitable sealant can be employed for this purpose.

A conventional cover orface plate 42, such as marble or the like, is generally positioned in front of each crypt by means of thebrackets 32 to identify the entombed deceased. Although only pairs ofbrackets 32 are shown in the drawing, it will be apparent that any suitable cover plate bracket can be employed. as for example, as described in U.S Pat. Nos. 2.853.870. 2,6l8.l45. and others.

Ventilation means (not shown) can also be provided to exhaust odors which emanate from each sealed crypt through opening 43 optionally provided at the rear wall of each crypt. A plenum chamber would be provided to communicate with openings in each crypt whereby odors could be drawn out to be externally vented.

To assemble the modular mausoleum crypt system according to the present invention, aconcrete base 10 is initially provided with appropriate footings. only partially shown in FIG. I. Thereafter. the assembly of precast modular units begins. preferably with the initial positioning of right end unit C or D with grooves provided in thebase 10. Each of the modular units is capable of being lifted by a crane by hooks temporarily affixed to the modular unit. Before the precast unit is positioned. a cementitious. settable grout is dispensed within the grooves which. after setting. permanently seals the precast unit to itsunderlying support base 10. After modular unit C or D is positioned. one or more intermediate modular units B is brought into abutting interlocking position with modular unit C or D. Prior to positioning each of the modular units. the grouting composition is dispensed within the ledges l7 and 25 to insure a properly sealed joint. The left end modular unit A is thereafter placed in interlocking abutting position with respect to already positioned intermediate unit B to complete tier l. The process is repeated for each of the next three tiers. or more if necessary. until the structure is finished. The finishing roof. and a suit able facingmaterial 35 is then applied to complete the structure. In some installations. the crypts cover plates confront an enclosed lobby where visitors can gather.

One suitable grout formulation useful for effecting fluid-tight joints includes a cement glue admixed with approximately pounds of cement. 200 pounds of sand. and a sufficient quantity of water to provide acceptable and well known workability. The cement glue can be an organic glue. e.g.. CRYSTAL CEMENT GLUE. manufactured by Wurdack Chemical Company. 4977 Fyler Avenue, St. Louis. Mo.
