Embodiment Construction

[0014] Such as figure 1 As shown, a thin-walled square box without ribs accurately locates the hollow floor construction method. Firstly, the formwork support 7 is built, and the floor formwork 8 is fixed on the formwork support 7. A total station and a level are used to support the floor formwork Accurately measure and place the positioning points and lines of the thin-walled square box; then start to bind the steel bars 10 at the lower part of the slab. 800-1200mm. The anti-floating iron wire 6 will pass through the floor formwork to bind the steel bar at the bottom of the plate and the formwork support 7 firmly;

[0015] Place the core mold positioning horse stool 9 above the floor template 8, and the positioning horse stool 9 is made of φ4mm cold-drawn steel wire, and the specific size is determined according to the actual project. After the positioning horse stool 9 is placed, the steel bar 10 at the bottom of the positioning horse stool 9 and the floor formwork is boun...

Abstract

The invention relates to construction methods, in particular to a thin-wall square box rib-free and accurate positioning hollow floor construction method. The problem that displacement is caused due to application of a thin-wall square box to a top board of a garage is solved. The construction method includes the steps that a form board support is built; a floor form board is fixed to the form board support; board lower steel bars and hidden beam steel bars are tied; anti-floating iron wires are arranged; the upper ends of the anti-floating iron wires are connected with the lower steel bars, and the lower ends of the anti-floating iron wires are connected with the form board support; a thin-wall square box is placed in a determined position; anti-floating steel bars are arranged above thethin-wall square box; tension bars are disposed between the anti-floating steel bars and the board lower steel bars; positioning steel bars are installed on the two sides of the thin-wall square box;the lower ends of the positioning steel bars are connected with the board lower steel bars; board upper steel bars are installed; the positioning steel bars are connected with the board upper steel bars; and finally concrete pouring is performed. Through the scheme, the thin-wall box can be tied to the steel bars in the top board of the garage and is completely fixed, displacement in the horizontal direction and the vertical direction cannot occur, the structural distribution is uniform, the stress is balanced, and the force-bearing effect is good.

Description

technical field [0001] The invention relates to a construction method, in particular to a construction method for a thin-walled square box without ribs and precisely positioned hollow floors. Background technique [0002] The thin-walled square box hollow floor is a kind of concealed beam cavity slab structure floor system composed of concrete and light building materials. At present, the application of the beamless hollow floor for the roof of the garage is more and more widely used. As a new type of material, the GBF thin-walled square box is used in the cast-in-place concrete hollow floor structure to reduce the weight of the floor, especially for the basement. The improvement effect is notable. However, due to the lack of effective fixing measures for the thin-walled square box, it is easy to cause the box to move and float up during construction. At present, it is urgent to find a simple and fast solution. [0003] CN 204081183 U discloses a thin-walled square box hol...
