Quick support system of high-rise steel structure house composite floor slab

Abstract

The invention discloses a quick support system of a high-rise steel structure house composite floor slab. The quick support system comprises H-shaped steel beams, support frames and precast slabs which are arranged symmetrically. Each H-shaped steel beam comprises an upper plane 1, a lower plane 2, and a longitudinal face 3, wherein the longitudinal face 3 connected with the upper plane 1 and the lower plane 2 is arranged in the vertical direction. Each support frame comprises height-adjustable U-shaped brackets 4 and a crossbeam 5, wherein the height-adjustable U-shaped brackets 4 are placed on the corresponding lower plane 2, and the crossbeam 5 is placed in U-shaped grooves of the corresponding height-adjustable U-shaped brackets 4. The crossbeams push upper flange slabs of the H-shaped steel beams through the height-adjustable U-shaped brackets, safety and reliability are achieved, and meanwhile dismounting is convenient; and large construction loads can be borne, groove steel is used as the support crossbeams, deflection of the precast slabs in the process of concrete pouring can be significantly reduced, and the molding quality of the floor slab is improved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a rapid support system for laminated floor slabs of high-rise steel structure buildings. Background technique [0002] The overcapacity of steel in my country exceeds 100 million tons. The steel structure building area accounts for more than 10% of the total building area in developed countries, more than 40% in the United States and Japan, and less than 5% in my country. As the country with the largest construction scale and steel output in the world, China has great potential for the development of steel structure buildings. In the construction process of laminated floors of steel structure buildings, support work is a very important link. [0003] The construction of laminated floors of steel structure buildings generally requires vertical support. Due to the characteristics of large area and high floors of steel structure workshops, some floors are more than 6 meters hig...

AI Technical Summary

Problems solved by technology

The traditional formwork is supported by vertical poles, and the length of the poles is relatively high and there is a risk of instability. Therefore, there are disadvantages such as high construction costs, slow construction progress, and large safety risks.
