Description
Technical Field
The utility model relates to a concrete pouring template supporting structure in the field of building construction, in particular to a supporting structure for an independent supporting post-cast strip floor slab template.
Background
Because the interval time between the concrete pouring of the floor slab and the post-pouring strip is long, the formwork supporting mode of the concrete pouring of the floor slab and the post-pouring strip at present mainly adopts two modes, one mode is that the floor slab and the post-pouring strip are supported together, in order to quicken the service cycle of a formwork and reduce the use cost of the formwork, the formwork is dismantled after the floor slab pouring and curing is completed and before the post-pouring strip is poured, and the mode of re-supporting (back jacking) the joint of the floor slab and the post-pouring strip (namely the cantilever end of the floor slab) while dismantling is adopted during the formwork dismantling, but the stress requirement cannot be met due to untimely re-supporting (back jacking) or re-supporting (back jacking), so that the stress requirement of the structure at the joint of the floor slab and the post-pouring strip (namely the cantilever end of the floor slab) is difficult to meet.
The other is to prevent the former situation, an independent template support system is used in a post-cast strip area, when the template and the support are removed, the post-cast strip area is not removed, and the original template support is reserved, the mode can mainly avoid the situation that the structure concrete strength ensures that the post-cast strip support system is provided when the strength is not reached or the upper part transmits load, but in the process of constructing the post-cast strip at last, when the construction joint of the post-cast strip is required to be cleaned, the original supported template must be removed again to be cleaned, and the support and the structure are separated, the mode is unreasonable in two aspects, firstly, the template supported in the post-cast strip area is a new template, so that the template and the batten are accumulated and pressed, and can not be reused, and the post-cast strip is allowed to be sealed for a long time, particularly, the post-cast strip is settled, and can be sealed after the main body is sealed, and the template is exposed to the sun, rain and damaged in other modes, the template is difficult to reuse; secondly, the top support of the support frame is at least loosened when the template is cleaned and dismantled, and at the moment, the joint of the floor slab and the post-cast strip (namely the cantilever end of the floor slab) still has an unsupported state, so that the stress on the structure is not good.
The post-cast strip formwork support system in the prior art adopts the steel pipe frame formwork to support independently, and can be dismantled after concrete pouring in the post-cast strip is finished and maintained for 28 days, and because the post-cast strip is left for too long time, a large amount of formwork and steel pipe materials are occupied for a long time, and the support material is easy to damage and even is dismantled manually. The materials such as the template, the square timber, the jacking and the like are easy to deform, rot, rust and the like, so that the template supporting system of the post-pouring belt is loosened. The frame body upright stanchion and the horizontal pole are dense, so that a construction channel is blocked, secondary structure construction is influenced, and the overall attractiveness is poor.
SUMMERY OF THE UTILITY MODEL
