Description

Technical Field

Background Art

It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roof engineering construction, decoration engineering construction, etc.

[0003] In the construction of the main structure of large shopping malls, the first and second floors of large shopping malls are basically glass curtain walls. For the sake of beauty, the second-floor beams and slabs generally adopt cantilever structures. The longer the cantilever length, the more beautiful it will be after the subsequent curtain wall construction because the frame columns are far away from the glass curtain wall. When the cantilever length of the second-floor beam and slab exceeds 5 meters and the cantilever structure above the second floor is used with a large load, the traditional cantilever structure with a large load adopts the method of increasing the cross-sectional size of the cantilever beam and the reinforcement. This method increases material and construction costs and is very uneconomical.

[0004] Therefore, it is hoped to provide a conversion structure from a cantilever structure to a frame structure, which can convert the cantilever structure of the non-glass curtain wall part above the second floor into a frame structure for load bearing, thereby reducing the amount of steel bars and concrete used and improving economy.
