Description

Quick and easy closing network template

technical field

The utility model relates to the technical field of construction engineering, in particular to a quick and easy closing net template.

Background technique

With the development of the economy, urban land resources are becoming more and more tense. In recent years, the number of super high-rise buildings built in China has begun to increase, and the thickness of the foundation floor and the diameter and amount of steel bars are also increasing. Due to the large height difference between the super high-rise tower and the podium, the design generally sets a post-settlement pouring belt on the floor at the junction of the tower and the podium to avoid damage to the foundation floor caused by uneven settlement during the construction of the building. Due to the large depth of the post-cast belt of the super-high-rise foundation floor, the large number of steel bars passing through the post-cast belt, and the narrow operating space, it is difficult to ensure that this type of post-cast belt does not leak grout and does not expand the formwork during the concrete pouring of the bottom slab according to the usual formwork construction technology. And mold running, and after grout leakage and mold running, it is difficult to clean the concrete grout between multiple rows of steel bars.

Compared with the prior art, the utility model has the following beneficial effects:

The fast and easy closing mesh formwork has improved and innovated the traditional formwork construction technology. It adopts concrete bar grouting at the bottom of the steel bars, quick and easy closing mesh + galvanized steel wire mesh caulking, and quick and easy closing mesh + The comprehensive construction technology of formwork with steel support formwork, tension bolt tie + steel pipe top brace reinforcement solves the problem of difficult construction of post-cast strips with super thick bottom slabs, and the construction quality of post-cast strips is effectively guaranteed.

This method solves the problem of grout leakage and sealing between multiple rows of steel bars passing through the post-casting belt by setting cast-in-situ concrete grout bars, quick-easy closing nets between multiple rows of steel bars, and galvanized steel wire mesh under the first row of steel bars. Difficult to block and difficult to clean; the quick-easy closure mesh + steel support formwork system is installed between the bottom plate and the lower skin steel bars, and the double-tension bolt tie + steel pipe top support method is adopted to solve the problem of deep post-casting belt and bottom plate. When the concrete is poured, a large lateral pressure is generated on the post-cast belt formwork, which is prone to the problems of mold expansion and run-out.

After the bottom slab concrete is poured, the surface of the quick-easy closing net can naturally form a pockmarked surface, without the need to remove the formwork and chiseling. It also solves the problem of difficulty in chiseling the joint surface of new and old concrete due to the dense reinforcement in the post-casting belt and the narrow operating surface. .

The implementation of this quick and easy closing mesh formwork is suitable for the formwork construction of the post-cast belt, reinforcement belt and construction joint position of the foundation floor with large thickness, dense steel bars, and many rows. The formwork construction of the location is also suitable.

The fast and easy closing net template is reasonable in design, simple in structure, safe and reliable, convenient to use and easy to maintain, and has good promotion and use value.
