Post-pouring belt concrete blocking device and using method thereof

Abstract

The invention discloses a post-pouring belt concrete blocking device and a using method thereof. The post-pouring belt concrete blocking device comprises a post-pouring belt upper steel bar, a post-pouring belt lower steel bar and a rubber inflating bag. When the post-pouring belt concrete blocking device is used, the post-pouring belt lower steel bar is bound and fixed, the rubber inflating bag which is inflated with 70%-80% of air is placed at the upper end of the post-pouring belt lower steel bar, and the post-pouring belt upper steel bar is mounted and bound at the upper end of the rubberinflating bag; then the rubber inflating bag is inflated with 100% of air; and concrete is poured to the two sides of the rubber inflating bag, and when the concrete strength reaches the formwork removing condition, air in the rubber inflating bag is released, and then the rubber inflating bag is taken out. The clearance between the post-pouring belt steel bars can be blocked after the rubber inflating bag is inflated, so that an interception effect is achieved when concrete is poured into a post-pouring belt; as the blocking device of post-pouring belt concrete, the rubber inflating bag has the characteristic of convenient assembly and disassembly; and the size of the rubber inflating bag after deflating is reduced, the rubber inflating bag can be directly pulled out from the clearance ofthe steel bars and can be reused, the construction period is shortened, the construction difficulty of workers is reduced, and meanwhile, materials are saved.

Description

technical field [0001] The invention relates to the field of construction, in particular to a blocking device for post-cast concrete and a method for using the same. Background technique [0002] At present, the traditional post-cast concrete blocking method is to bind steel wire mesh or quick-easy closing net at the post-casting strip. It is difficult to bind and fix the steel wire mesh and quick-easy closing net inside the steel bar. cause leakage. [0003] Although this method can block concrete to a certain extent, there are still relatively large disadvantages. Blocking with fast and easy closing net, the fast and easy closing net is too dense, and it is easy to form faults; blocking with dense steel wire mesh, it is easy to run out of slurry, and it is difficult to clean when it flows into the post-casting belt. The construction quality of the blocking net has a great influence Man-made, tying is difficult, resulting in construction difficulties, which will affect th...

Blocking with fast and easy closing net, the fast and easy closing net is too dense, and it is easy to form faults; blocking with dense steel wire mesh, it is easy to run out of slurry, and it is difficult to clean when it flows into the post-casting belt. The construction quality of the blocking net has a great influence Man-made, tying is difficult, causing construction difficulties, which affects the construction progress, and will also increase the cost of post-pouring belt cleaning in the later period
