The barb type latch floor of plastic materialTechnical field:
The present invention relates to a kind of building and ornament materials, be specifically related to a kind of dalle, be more especially the combinable floor decorative material that refers to a kind of plastic material preparation with plastic material preparation of elastic deformation.
Background technology:
Floor decorative material generally is used in family or public arena, uses pure floorboards of wood or complex intensifying floor to be the master generally speaking, and plastic floor also is a kind of floor decorative material commonly used; Two kinds of form of structure are arranged as the one of which, the one, large-area roll-good form, the 2nd, the square form of small size; The general character of the two is that thickness is all thinner, all needs large tracts of land gluing and ground bonding when using installation, uses through a period of time; After the concentrated wear, be difficult to safeguard, change also extremely inconvenient.Existing also have plastic floor to use the buckle structure that is similar to complex intensifying floor; For example the patent No. is the disclosed structure of ZL97190692.0; Its basic structure is the tongue that sheet material one end has a level to stretch out, and the other end has the groove of a level, and tongue and groove are chimeric and interconnect; This structure is fit to have the complex intensifying floor of suitable rigidity and thickness, but is not suitable for the floor of thin and softer plastic material preparation.Said structure is also comparatively time-consuming when mounted, and the length of the superposition section of tongue and groove can account for plate wide 3~5%, so when producing in enormous quantities; Loss is bigger; And other the defective that also has, it is yielding for example to meet water, and the consolidated floor material generally all uses formaldehyde as adhesive; Environment and people are had infringement, and the connection that how to solve the sheet material of softer plastic material preparation has practical significance.
Goal of the invention:
Goal of the invention of the present invention is the button-type structure that discloses a kind of connection of the strip boards that is suitable for plastic material preparation, it is effectively connected and has more multiple advantage.
Realize that technical solution of the present invention is following: comprise the sheet material of bar shaped plastic material preparation, it is fluted on one side, and relative another side has the tenon of corresponding inserted groove; Key is that the opening of groove makes progress; Tenon is downward, and groove and tenon are chimeric each other, and the included angle A between the plane of groove and sheet material is 50~80 degree; Constitute an oblique downward groove, tenon is suitable with this oblique downward groove.
Included angle A between the plane of described groove and sheet material is 60~70 degree.
A smooth curve changeover portion between described groove and the sheet material.
The inner angle of the end of described tenon and the outer hook portion of groove is the smooth curve transition.
One bending platform is arranged at the inner edge top of described groove, forms a bigger opening of groove.
One little gap is arranged between the inner edge of described tenon and groove, form the spatial accommodation of tenon distortion.
One little gap is arranged between the upper surface of the outer hook portion of described groove and the sheet material.
Though structure of the present invention is succinct; But the overhead structure that is connected to form horizontal direction between groove and the tenon; Both the inclined open of groove upwards and tenon be oblique downwards; The barb-shaped groove of this oblique setting and tenon structure, the connection of the strip boards that the plastic material that is particularly suitable for approaching prepares.Only need tenon be pressed into groove when installing and using, the moderate finite deformation amount that the high ductibility of plastic material or elasticity are brought in the process of press in can make tenon get into groove smoothly, and general solid wood or reinforced boards all can not be realized above-mentioned process of press in.Because above-mentioned overhead structure, the interlock effect is good especially after installing, and can not thread off because of the variation of ambient conditions; Exactly because the interlock effect is good, the good integrity of the sheet material after the connection, so need not be during installation on ground gluing; Make the installation process labor and material saving; And when plate surface has wearing and tearing, be easy to the sheet material of wear surface is taken out replacing, this also existing plastics floor decorative material is difficult to realize.Though therefore the present invention is simple in structure; But has outstanding practical effect; Opened up use field and the Geng Yi person of being used acceptance for the sheet material of plastic material preparation as decoration panel undoubtedly, the structure that the present invention provides is fit to all types of plastic property material, like PVC, PE or other synthetic materials.

The specific embodiment:
See also Fig. 1~Fig. 3, specific embodiment of the present invention is following: comprise thesheet material 1 of bar shaped plastic material preparation, this bar shapedsheet material 1 generally is that 8~15cm is wide; Length is about 50~100cm, is not limited to above-mentioned size certainly, and thickness can be several millimeters; Therefore this sheet material rigidity is less, promptly softer, its one side fluted 2; Relative another side has thetenon 3 of corresponding insertedgroove 2, and also there arecorresponding recesses 2 andtenon 3 in another relative limit, and this is a technique known; Then sheet material can be interconnected to the area that needs, and key is that the opening ofgroove 2 makes progress (shown in Figure 3)tenon 3 downward (illustrated in figures 1 and 2);Groove 2 is chimeric each other withtenon 3, and the included angle A between the plane of describedgroove 2 andsheet material 1 is 50~80 degree, constitutes an obliquedownward groove 2; Tenon 3 with should be oblique downwardgroove 2 suitable, promptly the outboard end ofgroove 2 forms anouter hook portion 6, the sheet material oftenon 3 and its one also forms a hook-type; This hook-type syndeton forms a barb-shaped structure, the soft sheet material that this barb-shaped structure is particularly suitable for approaching; During use,tenon 3 is placed on thegroove 2, the sheet material ofpressing element tenon 3 can be pressed intogroove 2 withtenon 3; In the process of press in; Theouter hook portion 6 ofgroove 2 one sides receives laterally the distortion that is extruded with oftenon 3, andtenon 3 is also stressed simultaneously has a distortion to himself sheet material outside, because the existence of the distortion of above-mentionedouter hook portion 6 andtenon 3; Thentenon 3 can get in thegroove 2; Aftertenon 3 got intogroove 2 fully, above-mentioned distortion disappeared and the adaptive and mutual interlock ofrealization groove 2 andtenon 3, and two sheet materials are connected.
For the process of press between above-mentionedtenon 3 and thegroove 2 smooth and easy; Included angle A between the plane of describedgroove 2 andsheet material 1 is 60~70 degree; The distortion that had both guaranteed process of press in is less relatively, can guarantee the interlock amount betweengroove 2 and thetenon 3 again, can not produce the dropout phenomenon in the use; In the deformation process of above-mentionedouter hook portion 6 andtenon 3; There is a stress to concentrate between thesheet material 1 that the root oftenon 3 is connected with one; Therefore the angle that forms betweentenon 3 and the material that one is connected partly is easy to generate the fine crack that stress causes; So the angle that betweentenon 3 andsheet material 1, forms partly is a smoothcurve changeover portion 4, thereby eliminates above-mentioned stress, avoids the damage oftenon 3 roots; In like manner, also be the curve rounding off between thesheet material 1 thathook portion 6 is connected with one outside above-mentioned, more smooth and easy for makingtenon 3 be pressed into the process ofgroove 2 simultaneously, theend 5 oftenon 3 is the smooth curve transition with theinner angle 7 of theouter hook portion 6 ofgroove 2.
One bending platform 9 is arranged on inner edge 8 tops ofgroove 2, and it makes the opening of opening portion ofgroove 2 bigger, then more is prone to maketenon 3 get intogroove 2 more easily, and is difficult for producing the obstruction that gets into.
One little gap 10 is arranged between the inner edge 8 oftenon 3 andgroove 2; Form the spatial accommodation oftenon 3 distortion; And maketenon 3 more be prone to be pressed intogroove 2, allow some leeway also for simultaneously cause flexible that expand with heat and contract with cold, can not makesheet material 1 convexity because of expansion; Simultaneously between the upper surface of theouter hook portion 6 ofgroove 2 andsheet material 1, a little gap is arranged, this gap makestenon 3 can be because of mismachining tolerance etc. not former thereby maketenon 3 can not be pressed intogroove 2 fully.
The present invention is simple in structure, but is particularly suitable for the connection of the sheet material of the less plastic material preparation of rigidity, and this plasticity sheet material can be rectangle or foursquare, and thickness can be less, like 3~5mm, also can adapt to thicker sheet material simultaneously.So back-off (hook) the type floor of plastic material disclosed by the invention, suitable material is extensive, handling ease; Be connected firmly; Installation process or change all very conveniently, the area of the lap of the sheet material coupling part of this structure only accounts for about 1.5~2% of the sheet material gross area simultaneously, the gross area that occupies far beyond the horizontally disposed groove and the tenon structure ofprior art 3~5% low many; When producing in enormous quantities, can practice thrift wide variety of materials.
