Freely combined diamond die with fixed bracket

Abstract

The invention relates to a reinforced concrete internal model, in particular to a freely combined diamond die with a fixed bracket, which comprises a fixed bracket and a plurality of small diamond dies, wherein adaptive sliding rails are respectively arranged on the fixed bracket and the small diamond dies, and the small diamond dies form the combined diamond die through arranging the sliding rails on the bracket. The fixed bracket comprises a cylinder shaft and four high-strength blades, wherein the blades are mutually vertically and uniformly fixed on the side wall of the cylinder shaft, and sliding rails adapted to the side walls of the square diamond dies are respectively arranged on the side surfaces of the blades along a clockwise direction or anticlockwise direction. The invention is convenient for positioning and easy for construction, is favorable for conveniently solving the contradiction of medium-small embedded parts and the installation of the box body, and is easy to ensure that the concrete is compact.

Description

【Technical field】 [0001] The invention relates to an inner form for a building floor, in particular to a reinforced concrete inner form used in the technology of cast-in-place hollow floor slabs. 【Background technique】 [0002] Reinforced concrete inner formwork is an important component used to manufacture concrete slab structures. Its main function is to hollow out the concrete, reduce the structural weight of the slab, and improve the mechanical performance of the slab structure at the same time. The cast-in-place hollow slab generally includes reinforced concrete and a hollow inner formwork. The hollow inner formwork is wrapped in the mandrel in the cast-in-place reinforced concrete to form ribs. The ribs are connected by steel bars. Therefore, the hollow inner film, steel bars and The cast-in-place reinforced concrete hollow floor slab composed of concrete has good force bearing and force transmission performance. The internal form of existing cast-in-place hollow floo...

AI Technical Summary

Problems solved by technology

[0003] 1. The installation and fixing are cumbersome and the construction efficiency is low; the large-volume box is transported and the installation is difficult

[0004] 2. The position of the inner mold is difficult to locate according to the design requirements, and the inner mold is easy to shift under the action of buoyancy and impact force during the construction process

[0005] 3. The compactness of the concrete is poor. Because the box is relatively large, and its bottom plate is closely attached to the bottom form of the floor, during the concrete pouring process, the concrete under the box is not easy to enter, and it is easy to cause cavities and honeycombs at the bottom of the floor to affect the floor concrete. construction quality

[0006] 4. Due to the large area of ​​the square box mandrel, it is difficult to arrange the square box mandrel when it meets the embedded parts of the floor or when the concentrated force is large. It is necessary to replace the square box mandrel with a solid concrete floor, which will cause a sudden change in the stiffness of the floor. Under load, it is unfavorable to the force of the floor
