Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and particularly relates to a quick-installing and easy-closing formwork structure for post-cast strips. Background Technique

[0002] A post-cast strip is a concrete strip reserved at corresponding positions of the foundation slab, wall, and beam according to design or construction specification requirements to prevent harmful cracks that may occur in the cast-in-place reinforced concrete structure due to uneven self-shrinkage or settlement.

[0003] At present, with the development of the construction industry, there are more and more high-rise, super-high-rise, and large-scale projects. The application of post-cast strips in projects is becoming more and more frequent. The treatment of post-cast strips has always been regarded as the key and difficult point of the project. If leakage of mortar or formwork displacement occurs during construction, it is very difficult to clean the concrete that has entered between the steel bars. After formwork displacement, a large amount of concrete flows into the post-cast strip, and it is extremely difficult to clean it out, which will have a great impact on the construction quality of the post-cast strip. The traditional formwork for the post-cast strip is usually made of wooden formwork in a comb shape, with steel bars passing through it, and then fixed with wooden squares and steel pipes. After the concrete is poured, the formwork support and the wooden formwork on the concrete surface are removed, and the concrete joint surface is chiseled, and then the concrete for the post-cast strip is poured later.

[0004] The above construction method is relatively cumbersome to operate, and due to the narrow space of the post-cast strip, it is difficult to remove the wooden formwork, and the chiseling quality is also difficult to guarantee, thus there are many defects in the quality of the poured structure.

[0005] The technical problem to be solved by this application is: to design a quick-installing and easy-closing formwork structure for post-cast strips that does not need to be removed and does not need to chisel the joint surface, and can also ensure the pouring quality. Content of the Utility Model

[0006] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a quick-installing and easy-closing formwork structure for post-cast strips that does not need to be removed and does not need to chisel the joint surface, and can also ensure the pouring quality.

[0007] The technical solution adopted by the utility model is: a quick-installing and easy-closing formwork structure for post-cast strips, which includes a steel bar support framework. One side of the steel bar support framework is provided with a quick-installing and easy-closing formwork fixedly connected thereto. The quick-installing and easy-closing formwork is provided with a number of formwork grooves, and both sides of the formwork grooves communicate with each other.

[0008] In some embodiments, the steel bar support framework includes an upper steel bar support framework and a lower steel bar support framework fixedly connected to the upper steel bar support framework.

[0009] In some embodiments, both the upper steel bar support framework and the lower steel bar support framework are provided with connecting bars fixedly connected thereto for enhancing stability.

[0010] In some embodiments, the quick-install closing net includes an upper closing net structure fixedly connected to the upper steel bar support framework and a lower closing net structure fixedly connected to the lower steel bar support framework.

[0011] In some embodiments, a number of closing net grooves are provided in both the upper closing net structure and the lower closing net structure. The closing net grooves are formed by stamping, and the protrusions of the closing net grooves face away from the side of the post-cast strip.

[0012] In some embodiments, a water-stop steel plate is further provided between the upper steel bar support framework and the lower steel bar support framework, and upward bending plates are provided on both sides of the water-stop steel plate.

[0013] In some embodiments, an upper bottom plate steel layer fixedly connected thereto is further provided at the upper end of the upper steel bar support framework, and a number of upper bottom plate main steel bars fixedly connected thereto are provided on the upper bottom plate steel layer.

[0014] In some embodiments, a lower bottom plate steel layer fixedly connected thereto is further provided at the lower end of the lower steel bar support framework, and a number of lower bottom plate main steel bars fixedly connected thereto are provided on the lower bottom plate steel layer.
