Abstract
The utility model relates to a backplane concrete structure for solving a large-area concrete shrinkage crack. The backplane concrete structure is characterized by comprising concrete cushion layers, at least two backplane concrete layers, reinforcing bars and a sediment pool, wherein the concrete cushion layers are poured on a foundation, the at least two backplane concrete layers are poured on the concrete cushion layers, a post-cast strip gap is retained between the two backplane concrete layers, the reinforcing bars are buried between the post-cast strip gap and the backplane concrete layers, and the sediment pool is arranged below the post-cast strip gap and is concaved towards the foundation. According to the backplane concrete structure for solving the large-area concrete shrinkage crack, the problem of the generation of the large-area concrete shrinkage crack can be solved, the quality in the clear-out of the post-cast strip gap can be ensured, the clearing speed is increased, and the construction period is shortened and the construction cost is saved.
Description
Technical field
The utility model relates to a kind of underplate concrete structure that large area concrete shrinks the slit that is used to solve.
Background technology
After once property was built large area concrete on the ground, the shrinkage stress because of large area concrete produced distress in concrete easily.The slit, ater-casting is set between concrete to be used for building at last; It is one of construction means commonly used in building at present; The slit, ater-casting can break up the shrinkage stress of large area concrete effectively, reduces the generation of distress in concrete, but if working measure is improper; The construction quality in slit, ater-casting then is difficult to guarantee that the slit, ater-casting also can become the weakness band of concrete structure.
Traditional method is as depicted in figs. 1 and 2: by design elevation concreting bed course, the ater-casting gap position is reserved in assembling reinforcement then, then waters and smashes the underplate concrete layer earlier.Cleaning is during the slit, ater-casting, needs in intensive beam, slab muscle, cut a hole prune job such as to pick, slag tap, and the cleaning work amount is big, and expense is high, and construction effect is not good.
Summary of the invention
In order to solve existing in prior technology the problems referred to above; The utility model provides a kind of underplate concrete structure that large area concrete shrinks the slit that is used to solve; It both can solve large area concrete and shrink the problem that the slit produces; Can guarantee the cleaning quality in slit, ater-casting again, improve cleaning speed, save construction period and operating expenses.
The utility model technical scheme is to constitute like this; A kind ofly be used to solve the underplate concrete structure that large area concrete shrinks the slit, it is characterized in that: it comprises the concrete cushion of building in the ground top, build in the concrete cushion top and leave each other the slit, ater-casting the underplate concrete of twice at least layer, be embedded in the reinforcing bar between slit, ater-casting and each the underplate concrete layer and be located at below, slit, ater-casting and to the recessed detritus tank of ground direction.
The operating principle of the utility model technique scheme is explained as follows: owing to below position, slit, ater-casting, be provided with detritus tank; Therefore when cleaning slit, ater-casting; The concrete residue that cuts out etc. can directly be fallen in the detritus tank, and after the leveling, surface layer is smeared cement sand bed to concordant with the upper surface of second concrete cushion; Can accomplish cleaning work, continue the follow-up of slit, ater-casting built.
Compared to prior art, the utlity model has following advantage: the utility model both can solve large area concrete and shrink the problem that the slit produces, and can guarantee the cleaning quality in slit, ater-casting again, improved cleaning speed, saved construction period and operating expenses.

The specific embodiment
Below in conjunction with the Figure of description and the specific embodiment the utility model content is elaborated:
Being illustrated in figure 3 as a kind of being used to that the utility model provides solves the embodiment organigram that large area concrete shrinks the underplate concrete structure in slit, it is characterized in that: said be used to solve underplate concrete structure that large area concrete shrinks the slit comprise the concrete cushion 2 of building in ground 1 top, build in concrete cushion 2 tops and leave each other slit, ater-casting 3 the underplate concrete of twice at least layer 4, be embedded in the reinforcing bar 5 between slit, ater-casting 3 and each the underplate concrete layer 4 and be located at 3 belows, slit, ater-casting and to the recessed detritus tank 6 of ground 1 direction.
Said concrete cushion 2 is being formed by connecting at first concrete cushion 2-1 between underplate concrete layer 4 and the ground 1 and the second concrete cushion 2-2 between detritus tank 6 and ground 1.
Claims (2)
