Abstract
Description
Technical Field

[0002] To improve the bearing capacity of the floor structure, a double-layer steel bar mesh is usually adopted, and the two layers of steel bar meshes are respectively arranged close to the upper and lower surfaces of the floor. To ensure that the upper steel bar mesh is arranged close to the upper surface of the floor, when binding the upper steel bar mesh, it is usually necessary to set up stools welded by steel pipes on the formwork, rely on the stools to arrange the steel bars to be bound, and then carry out the steel bar binding operation. After the binding of the upper steel bar mesh is completed, the stools are left in the double-layer steel bar mesh. Although this method can realize the binding operation of the upper steel bar mesh, the stools penetrate the concrete floor. As time goes by, the metal stools are prone to rust, which may cause leakage of the floor, and the stools left in the steel bar mesh cannot be taken out, which undoubtedly increases the construction cost.

The binding and positioning support includes a lower support pulley, an upper support pulley, a frame body, a positioning plate. The lower support pulley is installed at the lower side of the frame body, the upper support pulley is installed at the upper side of the frame body. The lower support pulley supports the longitudinal steel bars on both sides of the lower steel bar mesh, and the longitudinal steel bars on both sides of the upper steel bar mesh support on the upper support pulley.

Gradually push the binding and positioning support forward to complete the binding operation of the upper steel bar mesh. After the binding is completed, remove the positioning plate from the frame body, and move the frame body together with the support pulleys out from between the double-layer steel bar meshes. Through the binding and positioning support, the accurate positioning of the upper steel bar mesh can be realized, and the overhead binding operation of the upper steel bar mesh can also be realized.
[0005] Preferably, a fastening bolt is arranged on the fixed sleeve, and by tightening the fastening bolt, the positioning plate can be prevented from falling off from the fixed sleeve.

[0008] Preferably, grooves are provided on the surfaces of the upper and lower support pulleys, and the grooves fit the steel bars, so as to prevent the support pulleys from slipping off the longitudinal steel bars.
[0009] Adopting the technical solution provided by the present utility model, compared with the prior art, it has the following beneficial effects:
[0010] 1. The tying and positioning bracket adopts a detachable structure and can be taken out from between the upper and lower steel bar meshes after tying, which can not only prevent the bracket from penetrating the floor slab structure and causing leakage of the floor slab, but also reduce the construction material cost of the floor slab.
[0011] 2. Compared with the traditional support stool which needs to carry out tying operations after the steel bars are arranged, and the steel bars are extremely easy to shift before tying after arrangement, thus affecting the tying and positioning accuracy of the steel bars; the tying and positioning bracket proposed by this technology does not need to carry out the arrangement operation of the steel bars, and can position the steel bars at any time according to the progress of the tying operation, reducing the on-site operation volume and improving the tying and positioning accuracy of the steel bars.
