Description

Technical Field

[0001] The invention relates to the technical field of roof casting, in particular to a large-slope cast-in-place concrete inclined roof formwork structure. Background Art

[0002] A pitched roof refers to a roof with a certain slope. In the prior art, the formation of a pitched roof requires first completing the main structure of the building, then casting and forming load-bearing columns on the roof, building a completed roof formwork based on the load-bearing columns, and then pouring concrete in the roof formwork.

[0003] After searching, the publication number CN116005948A provides a large-slope cast-in-place concrete sloping roof formwork structure, which relates to the field of building construction, including: a top support plate, the top of the top support plate is rotatably connected to each other, a strip groove is opened on the top of the top support plate, a longitudinal sleeve is fixedly connected to the top of the strip groove, a support rod is fixedly connected to the top of the longitudinal sleeve, and transverse plates are fixedly connected to the left and right facades of the longitudinal sleeve, a bottom plate groove is opened on the inner bottom of the top support plate, and side grooves are opened on the left and right sides of the top of the top support plate, and the bottom of the side groove is connected with the bottom plate groove. After the extension frame is dragged downward from the inside of the top support plate, the bottom of the extension frame can be slid to the end of the sloping roof, which is convenient for adapting to sloping roofs of different lengths. After the hinged part of the top support plate is placed on the top of the ridge, the top support plates on the left and right sides can be fitted and deflected with the sloping roof, so that sloping roofs of different slopes can be adaptively supported, which solves the problem that the existing formwork structure is not convenient for adaptively supporting sloping roofs of different slopes and lengths.

[0004] In the construction of sloping roofs with large slopes, vibration is a key step to ensure that the concrete is uniformly compacted. However, due to the large slope of the formwork structure in the above scheme, the insertion and operation space of the vibrating rod is limited, and the vibration effect is difficult to ensure, which in turn affects the density of the concrete and makes it difficult to ensure the pouring quality of the roof.

[0005] Therefore, we propose a large-slope cast-in-place concrete sloping roof formwork structure to solve the existing problems. Summary of the invention
