Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction tools technology, specifically to a spacer block for ensuring the position of steel reinforcement bars in the floor. Background Technology
[0002] Currently, when constructing insulated flooring or other types of rigid flooring, steel reinforcement is often used to prevent cracking. Generally, the anti-crack reinforcement is required to be placed slightly above the surface layer. However, during on-site construction, there are no particularly good measures to ensure the position of the reinforcement mesh, and it is easily collapsed during construction, causing the reinforcement mesh to sink to the base layer and fail to achieve its anti-crack effect. Based on this background, there is a need to develop a device to ensure the position of the floor reinforcement. Utility Model Content
[0003] The purpose of this invention is to provide a spacer block for ensuring the position of reinforcing steel bars in the floor, so as to solve the above-mentioned shortcomings in the prior art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a pad for ensuring the position of reinforcing steel bars in a floor, comprising: a pad, a support plate inserted on the top of the pad, a second through hole on the pad, a third through hole connected to the second through hole on the support plate, a threaded sleeve embedded in the inner wall of the second through hole, a stud threadedly connected to the threaded sleeve, and a hook rotatably disposed below the stud.
[0005] Furthermore, the bottom of the stud is connected to a ring via a steel wire rope, and a stop block is fixedly connected to the bottom of the ring. The hook is rotatably mounted on the stop block.
[0006] Furthermore, a fourth through hole is provided on the abutment block, and a circular piece is fixedly connected to the top of the hook after passing through the fourth through hole.
[0007] Furthermore, the top of the pad has two first through holes arranged symmetrically with respect to the second through hole, and the bottom of the foot plate has two inserts that are inserted into the first through holes.
[0008] Furthermore, a support foot is fixedly connected to each of the bottom two sides of the pad.
[0009] Furthermore, a hexagonal prism is fixedly connected to the top of the stud.
[0010] In the above technical solution, the present invention provides a beneficial effect for ensuring the position of the reinforcing steel reinforcement in the floor:
[0011] 1. This utility model uses an inverted U-shaped pad, which allows the steel mesh to be laid on the bottom surface first, and then the pad is installed. Compared with traditional pads, this is easier to place and adjust the position of the pad. The top surface of the pad is located above the steel mesh, and the foot plate can act as a stepping stone for construction workers, preventing them from stepping on the steel mesh and making their footing more stable and user-friendly.
[0012] 2. By setting studs inside the spacer block and connecting hooks for hooking the reinforcing bars at the bottom of the studs with wire ropes, the studs can be screwed into the third through hole using a hex wrench, which in turn pulls the reinforcing mesh to move vertically, so that the reinforcing bars are pressed against the bottom of the spacer block, thus lifting and clamping the reinforcing mesh.
[0013] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.
[0024] Please see Figures 1-5 A pad for ensuring the position of reinforcing steel bars in a floor includes: a pad 1, a support plate 2 inserted on the top of the pad 1, a second through hole 12 on the pad 1, a third through hole 22 on the support plate 2 that communicates with the second through hole 12, a threaded sleeve 4 embedded in the inner wall of the second through hole 12, a stud 5 threadedly connected to the threaded sleeve 4, and a hook 10 rotatably disposed below the stud 5.
[0025] Specifically, this utility model uses an inverted U-shaped pad 1, which allows the steel mesh to be laid on the bottom surface first, and then the pad 1 to be installed. Compared with the traditional pad 1, this is easier to place and adjust the position of the pad 1. Moreover, the top surface of the pad 1 is located above the steel mesh, and the foot support 2 can act as a stepping stone for construction workers, preventing them from stepping on the steel mesh and making their footing more stable and user-friendly.
[0026] Furthermore, the bottom of the stud 5 is connected to a ring 7 via a wire rope 6, and a stop block 9 is fixedly connected to the bottom of the ring 7. The hook 10 is rotatably mounted on the stop block 9, and a fourth through hole 91 is opened on the stop block 9. The top of the hook 10 passes through the fourth through hole 91 and is fixedly connected to a disc 101. A hexagonal prism 51 is fixedly connected to the top of the stud 5.
[0027] Specifically, by turning the stud 5 with the hexagonal screwdriver used with the hexagonal prism 51, the stud 5 rotates inside the screw sleeve 4, allowing the stud 5 to move vertically. This, in turn, moves the wire rope 6, the ring 7, the stop block 9, and the hook 10, ultimately causing the wire rope 6, the ring 7, and the stop block 9 to extend into the screw sleeve 4. The steel bar hooked on the hook 10 rests against the bottom of the pad block 1, thus fixing the steel mesh.
[0028] Furthermore, two first through holes 11 are symmetrically arranged about the second through hole 12 on the top of the pad block 1. Two inserts 21 are fixedly connected to the bottom of the foot plate 2 and inserted into the first through holes 11. By inserting the two inserts 21 into the first through holes 11, the foot plate 2 and the pad block 1 are assembled together. The bottom sides of the foot plate 2 are in contact with the ground, which enhances the stability of the pad block 1. The top surface of the foot plate 2 acts as a stepping stone, which makes it easier for construction workers to have a foothold when pouring the floor. Compared with stepping on the steel mesh, it is safer and more reliable, and at the same time, it avoids the steel mesh being stepped on.
[0029] Furthermore, a support foot 3 is fixedly connected to each side of the bottom of the pad 1. By setting the support foot 3 at the bottom of the pad 1, the stability of the pad 1 when supporting the steel mesh is enhanced. The pad 1 and the support plate 2 are both made of concrete. The screw sleeve 4 is a plastic screw sleeve embedded in the pad 1. The stud 5 is threadedly connected to the internal thread of the screw sleeve 4 through the external thread on the outside.
[0030] In this utility model, reference Figures 1 to 5 First, the steel mesh is laid at the construction site. Then, the construction worker holds a pad 1 and steps into the gaps in the steel mesh, placing the two feet of the pad 1 on either side of a steel bar in the steel mesh. Next, the worker holds the hook 10 to hook the steel bar on the steel mesh, and uses a hexagonal screwdriver to turn the stud 5, causing the stud 5 to move the steel mesh hooked by the hook 10 upwards until the wire rope 6, the ring 7, and the abutment 9 are all inside the screw sleeve 4, and the steel bar is against the bottom of the pad 1. By using multiple pads 1, the steel mesh is lifted and clamped. Finally, the foot plate 2 is inserted into the first through hole 11 through the insert 21 and assembled on the top of the pad 1 to act as a stepping stone, and the stud 5 extending out of the second through hole 12 is located in the third through hole 22. Later, the foot plate 2 is covered by pouring concrete.
[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
