Fabricated integrated house steel bar truss floor support plate and assembling method

Abstract

The invention provides a fabricated integrated house steel bar truss floor support plate and an assembly method. The fabricated integrated house steel bar truss floor support plate comprises an upper chord reinforcing steel bar, two web member reinforcing steel bars and two lower chord reinforcing steel bars, the two web member reinforcing steel bars and the two lower chord reinforcing steel bars are located on the two sides of the upper chord reinforcing steel bar respectively, each web member reinforcing steel bar is bent into a wave shape, the wave crest bending position of each web member reinforcing steel bar is an upper connecting end, the wave trough bending position of each web member reinforcing steel bar is a lower connecting end, upper connecting sleeves are arranged at the upper connecting ends of the web member steel bars, upper penetrating grooves are formed in the upper connecting sleeves, the upper connecting sleeves on the two web member steel bars are connected in an inserted mode, upper penetrating grooves in the two upper connecting sleeves which are connected in an inserted mode are communicated, and the upper chord steel bars penetrate through the upper penetrating grooves in all the upper connecting sleeves at the same time. The fabricated integrated house steel bar truss floor support plate is high in structural stability and low in welding and assembling operation difficulty, the project progress is accelerated, the bottom is flat, and the decoration cost is reduced.

Description

technical field [0001] The invention relates to a prefabricated building structure, in particular to a prefabricated integrated building steel bar truss floor deck and an assembling method. Background technique [0002] The traditional reinforced truss floor deck structure is as attached figure 1 As shown, it includes an upper chord reinforcement 1 and two lower chord reinforcements 3. The upper chord reinforcement 1 and the lower chord reinforcement 3 are distributed in a triangular position, and a web reinforcement 2 is arranged between the upper chord reinforcement 1 and the lower chord reinforcement 3. The web The steel bar 2 is bent into a wave shape, the crest bending position of the web steel bar 2 is the upper connection end 21, the wave trough bending position of the web steel bar 2 is the lower connection end 22, and the upper connection end 21 is welded to the upper chord steel bar 1, The lower connecting end 22 is welded to the upper chord steel bar 1 .

AI Technical Summary

Problems solved by technology

[0003] Since the overall length of the upper chord steel bar 1 and the lower chord steel bar 3 is relatively long, the positions of the web steel bar 2, the upper chord steel bar 1, and the lower chord steel bar 3 need to be relatively initially fixed during the welding process, but because the upper chord steel bar 1 itself is longer And it will involve connecting two web steel bars 2 at the same time. Even if the two ends of the upper string steel bar 1 are properly positioned, the closer the upper string steel bar 1 is to the middle, the greater its deformation will be, and the welding and assembly operation will be difficult.
