[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments and features in the present application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] See Figure 1 .

[0018] The structure of the steel bar cushion block for the floor slab protection layer of the utility model includes an elevation block 1, an upper cushion block 2, a connecting block 3, and a lower cushion block 4 that are sequentially arranged from top to bottom and form a "soil" shape. The upper cushion block 2 is correspondingly located on both sides of the elevation block 1, and the lower cushion block 4 is correspondingly located on both sides of the connecting block 3 and is respectively provided with grooves 201 for placing steel bars. The two grooves 201 of the upper cushion block 2 and the two grooves 201 of the lower cushion block 4 are arranged in parallel, and the two grooves 201 of the upper cushion block 2 and the two grooves 201 of the lower cushion block 4 are in one-to-one correspondence, and the corresponding two grooves 201 are arranged in parallel in the same vertical direction.

[0019] The steel bar pads for the protective layer of the floor slab of the present invention can restrict the positioning of the steel bars through the grooves 201 of the upper pad 2 and the lower pad 4, and the spacing between the upper and lower layers of steel bars is kept consistent by the receiving block 3. The upper and lower layers of steel bars are protected by the height setting of the elevation block 1 and the lower pad 4 respectively. The two grooves 201 of the upper pad 2 and the lower pad 4 are set. When used, the upper pad 2 and the lower pad 4 each use one groove 201. No steel bars are placed in the groove 201 on the other side for standby use, so as to prevent the groove 201 on one side from being damaged. The utility model has strong practicality.

[0020] And when this application is used, it is evenly arranged according to the principle of 4 pads per square meter according to the requirements of the specification. The lower layer of the floor slab steel bars are placed in the groove 201 on one side of the lower pad 4, and the other groove 201 is not placed with steel bars. The upper layer of the floor slab steel bars are placed in the corresponding groove 201 of the upper pad 2. During the pouring of the floor slab concrete, the elevation and horizontal plane of the concrete surface can be controlled according to the elevation block 1;

[0021] Moreover, when used, the present application can also replace the steel bar horse stool in the prior art.

[0022] In this embodiment, see Figure 2 The sides of the lower pad 4 are gradually tilted outwards from top to bottom. This design maintains the stability of the bottom.

[0023] In this embodiment, see Figure 3 The elevation block 1 and the receiving block 3 both include a threaded column 101 and a sleeve 102 threadedly connected to the threaded column 101. This design allows the elevation block 1 and the receiving block 3 to be height-adjustable, thereby making the elevation and horizontal plane of the concrete surface, as well as the spacing between the upper and lower floor reinforcement layers, controllable. In this embodiment, the threaded column 101 of the elevation block 1 is disposed on the upper pad 2, while the threaded column 101 of the receiving block 3 is disposed on the lower pad 4.

[0024] In this embodiment, see Figure 3 , a spring 103 is further provided in the sleeve 102. This design allows the sleeve 102 to be rotated to adjust the height and still remain stable, and in this embodiment, the spring 103 is always in a compressed state.

[0025] In this embodiment, see Figure 3 The elevation block 1 and the receiving block 3 further include a plurality of columns 104 arranged around the threaded column 101, and each column 104 is provided with scales. This design allows the height adjustment to be determined by observing the scales on the columns 104 corresponding to the bottom of the sleeve 102. For example, for the receiving block 3, the lowest point of the scale on the column 104 can be set to the height of the receiving block 3 when it is not adjusted. The subsequent scales from the bottom right to the top are the height of the receiving block 3 when it is not adjusted + the actual number of centimeters.

[0026] In this embodiment, referring to Figure 3 , the upper cushion block 2 and the receiving block 3 are connected by a plurality of screws 5, and the plurality of screws 5 are symmetrically arranged with the central axis of the elevation block 1 as the symmetry axis. Such a design enables the upper cushion block 2 and the receiving block 3 to be detachable. When the groove 201 of the upper cushion block 2 is damaged, the alignment adjustment can be quickly performed through the symmetry of the screw holes.

Those skilled in the art can make various modifications or changes according to it. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.

[0028] It should be noted that if there are directional indications such as up, down, left, right, front, back... in the embodiments of the present invention, then such directional indications are only used to explain the relative position relationship and movement conditions between components in a specific posture as shown in the drawings. If this specific posture changes, then the directional indications will also change accordingly.
