Technical Field
The utility model relates to a building field, more specifically say, it relates to a wear floor pipeline concrete formwork structure.
Background
In the building construction process, some pipelines, such as water pipes, exhaust pipes and the like, need to be laid frequently, some holes need to be reserved in the floor slab at this time for the pipelines to pass through, and after the pipelines pass through, a formwork structure needs to be used for pouring concrete for sealing.
The most common method in the prior art is to adopt two semicircular wood templates to be lapped together for mold hanging construction to form a cavity for pouring, and then the wood template is dismantled after pouring is finished. The technical scheme is simple and feasible, but the concrete surface obtained by pouring has poor compactness and is easy to leak, and a large amount of cement paste is lost in the pouring process. The main reason for such a phenomenon is that there is a gap between two wood formers, and the reason for such a gap is various, for example: the gap is generated between the wood mould and the pipeline due to non-matching roundness or vibration displacement of the two templates during pouring, the gap is generated between the two templates due to lapping, the gap is generated between the wood mould and the concrete floor due to poor floor flatness or the deformation of the template caused by excessive force during mould hanging, and the gap is generated between an iron wire for hanging the mould and the templates.
In order to solve the problem of the gap in the prior art, the chinese utility model patent with patent grant number CN203499250U discloses a concrete formwork structure for floor-penetrating pipeline, such a structure adopts polystyrene plastic plate as supporting tight seal structure, can utilize the sufficient characteristics of elasticity of polystyrene plastic plate well, can greatly reduce the existence of template gap.
