Description

Technical Field

[0001] The utility model relates to the field of construction engineering, in particular to a hollow floor slab filling component cushion block and positioning device. Background Art

[0002] Generally, a steel mesh box is installed in the concrete hollow floor of the basement. There is a certain thickness of concrete on both the upper and lower layers. The steel mesh box is installed in the middle position. The steel box is placed between the steel bars of the upper and lower floors, and the concrete pad is placed below. The plane position is located in the middle of four reinforced concrete beams. When pouring concrete, the plane position of the mesh box may shift due to the pushing effect of the concrete on the steel mesh box, affecting the thickness of the protective layer of the steel bars in the surrounding concrete beams. At the same time, the concrete pushes the mesh box upward, causing the mesh box to move upward, affecting the thickness of the upper concrete floor, thereby affecting the quality of the overall concrete hollow slab. Summary of the invention

[0003] In view of this, the purpose of the present invention is to provide a hollow floor filling component pad block and positioning device to solve the problems raised in the above background technology.

[0004] In order to achieve the above purpose, the technical solutions adopted are as follows:

[0005] A hollow floor filling component pad and positioning device, comprising a square pad, a limiting groove is arranged on the top of the square pad, two adjacent inner side walls of the limiting groove form right-angle walls, and the other two edges of the limiting groove are open structures for placing and limiting the hollow mesh box;

[0006] A lead wire for tying the hollow net box is fixedly connected to the bottom of the limiting groove.

[0007] As a further improvement of the present invention, the thickness of the inner wall of the limiting groove is equal to the distance between the hollow floor slab and the concrete beam.

[0008] As a further improvement of the utility model, the thickness from the bottom of the limiting groove to the bottom of the square pad is the thickness of the lower floor slab.

[0009] As a further improvement of the present invention, the bottom of the limiting groove is square.

[0010] The beneficial effects of the utility model are:

[0011] Set square pads at the diagonal corners of the hollow net box on the floor slab, put the corners of the hollow net box into the limit groove, and the diagonally set pads are just stuck between the concrete beam and the hollow net box, so that the upper, lower, left and right positions of the hollow net box are just at the designed position;

[0012] The special-shaped dimensions of the square pads ensure that the steel mesh box is positioned accurately in the concrete floor slab, thereby ensuring the construction quality of the overall concrete hollow floor slab. BRIEF DESCRIPTION OF THE DRAWINGS
