Description

A kind of Joining Technology of precast concrete terrace

Technical field

The present invention relates to construction engineering technical field, and in particular to a kind of Joining Technology of precast concrete terrace.

Background technology

At present, the development of China Logistics warehouse is swift and violent, and the terrace area of logistics is larger, using traditional cast in place process, notThe needs of grassroot project development at this stage can be met, therefore, to avoid dust during the cast-in-place surface production of tradition, water resourceThe environmental issues such as waste, noise, reduce scene manually, solve the problems, such as labor service personnel's shortage, and accelerate construction period, need badly openHair studies a kind of precast concrete terrace connected mode.

The content of the invention

In view of the shortcomings of the prior art, the present invention seeks to be to provide a kind of connection of precast concrete terraceTechnique, it can significantly accelerate construction period, it is simple to operate, it is easy for construction, it is quality controllable, reduce scene manually, effectively avoid giving birth toDust, water resource waste and noise during production, the feature of environmental protection is more preferable, use easy to spread.

To achieve these goals, the present invention is to realize by the following technical solutions：A kind of precast concrete terraceJoining Technology, its step is：(1) prefabricated terrace plate is transported to scene from factory first, transported to by handling appliance specifiedInstallation site；

(2) measurement absolute altitude production technique concrete stool, then rammed earth；

(3) it is the earthwork is smooth and roll, pour 70mm thickness C15 plain concrete pads；

(4) the prefabricated terrace plate of handling again；

(5) assembled prefabricated terrace plate；

(6) the node band between contiguous prefabricated terrace plate is finally poured, is finally completed whole terrace.

Preferably, the prefabricated terrace plate includes component high position pre-erection and the pre-erection of component low level half, pass throughPunching block assembles, then by connecting reinforcing bar colligation, and then C30 concrete is poured, completed finally by maintenance form removal whole pre-Terrace component processed.

Preferably, the described pre-erection cloth of component low level half is in component high position pre-erection surrounding 400mm, using halfMethod for prefabricating is secondary cast-in-place again when assembly overlaps at the scene, cast-in-place into a complete terrace.

Beneficial effects of the present invention：(1) prefabricated terrace early stage can shift to an earlier date Prefabrication in factory, significantly accelerate constructionCycle；

(2) prefabricated floor construction is convenient, simple to operate, effectively solves the problems, such as labor service personnel's shortage, and it is artificial to reduce scene；

(3) effective dust, water resource waste and noise avoided in production process, the feature of environmental protection are more preferable；

(4) processing quality is controllable, meets the needs of grassroot project development at this stage.

Embodiment

To be easy to understand the technical means, the inventive features, the objects and the advantages of the present invention, with reference toEmbodiment, the present invention is expanded on further.

Reference picture 1-7, present embodiment use following technical scheme：A kind of connection work of precast concrete terraceSkill, its step are：(1) prefabricated terrace plate 1 is transported to scene from factory first, the installation position specified is transported to by handling appliancePut；

(2) measurement absolute altitude production technique concrete stool 2, then rammed earth；

(3) it is the earthwork is smooth and roll, pour 70mm thickness C15 plain concretes pad 3；

(4) the prefabricated terrace plate 1 of handling again；

(5) assembled prefabricated terrace plate 1；

(6) the node band 4 between contiguous prefabricated terrace plate 1 is finally poured, is finally completed whole terrace.

It is worth noting that, the prefabricated terrace plate 1 includes half prefabricated portion of component high position pre-erection 101 and component low levelDivide 102, assembled by the high-precision punching block of the standard of customization, then by connecting the colligation of reinforcing bar 5, and then pour C30 concrete6, the whole prefabricated terrace component completed finally by maintenance form removal.The specific mounting process of prefabricated terrace plate includes following stepSuddenly：1. the prefabricated terrace of every piece of handling to scene；2. assembled prefabricated terrace；3. place colligation cast-in-site stripe bar-mat reinforcement；4. use coagulationSoil pours the cast-in-site stripe one complete terrace of completion for building up prefabricated terrace.

The described pre-erection 102 of component low level half is distributed in the surrounding 400mm of component high position pre-erection 101, using halfMethod for prefabricating is secondary cast-in-place again when assembly overlaps at the scene, cast-in-place into a complete terrace.

Present embodiment provides a kind of connected mode of new precast concrete terrace, using split blade type nine gridsScheme is split, and using prefabrication+cast-in-place connection scheme of on-site consolidation+part, precast concrete terrace is mainly adopted by surroundingWith a kind of combination overlapping mode of overlapping system+integral prefabricated, precast concrete terrace is prefabrication in advance, prefabricated terrace plateSurrounding 400mm uses half method for prefabricating secondary cast-in-place again when assembly overlaps at the scene, cast-in-place into a complete terrace.

The prefabricated system that present embodiment uses compares existing traditional technology mode, can shorten building site ground and applyThe work duration, services dispatch is reduced, while avoid the rings such as dust in the cast-in-place terrace production process of tradition, water resource waste, noiseGuarantor's problem, avoids the common quality defect of the cracking of the cast-in-place terrace of tradition, and Joining Technology has easy to operate simple, and connected modeIt is simple and reliable, the advantages of being easy to execute-in-place, there is wide market application foreground.

The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The technology of the industryPersonnel are it should be appreciated that the present invention is not limited to the above embodiments, and the simply explanation described in above-described embodiment and specification is originallyThe principle of invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changesChange and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and itsEquivalent thereof.
