The steel bar is passed through the hole of the round cake-shaped cushion block, and the distance between the steel bar and the formwork (concrete cover) is controlled by the cushion block. Finally, after pouring the concrete, the cushion block and the concrete form an integral body. Since the existing round cake-shaped cushion blocks can only pass the steel bar through the reserved hole of the round cake cushion block, after the steel bar binding is completed, it is impossible to add more cushion blocks, which makes the construction very inconvenient. For this reason, the present utility model is specifically proposed. Summary of the Utility Model

[0035] In order to enable those skilled in the art to better understand the technical solutions in the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0036] The concrete cushion block is a component used in construction engineering. It is mainly used to ensure the position of steel bars in concrete and the thickness of the protective layer, and to prevent the steel bars from being exposed and corroded. It is generally made of materials such as cement, sand, and stone, and has characteristics such as high strength and good durability. The existing round cake-shaped cushion blocks can only be used by passing steel bars through the reserved holes in the round cake cushion blocks. After the steel bars are tied, it is impossible to add more cushion blocks, which is very inconvenient for construction.

[0037] The concrete cushion block provided by this application has a round hole 2 provided in the middle of the cushion block main body 1, and a through groove 3 communicating with the round hole 2 is provided at the first end of the round cushion block. The steel bar enters the round hole 2 from the through groove 3, so as to be connected and used with the steel bar after tying. Moreover, through the eccentric structure design, after being connected with the steel bar, self-stability can be achieved and it will not fall off, which greatly facilitates the construction of highway engineering.

[0038] The following will describe in detail the specific structure of the concrete cushion block provided by this application with reference to the accompanying drawings.

[0039] Embodiment 1:

[0040] Referring to Figures 1-4 As shown, the embodiment of this application provides a concrete cushion block, including a cushion block main body 1;

[0041] The cushion block main body 1 is a round cushion block. The round cushion block has opposite first and second ends. The thickness of the round cushion block gradually decreases from the first end to the second end, and the center of gravity of the round cushion block is biased towards the first end. As Figure 2 shown, Figure 2 In the figure, the bottom end of the round cushion block is the first end, and the top end is the second end. The thickness of the bottom end of the round cushion block is greater than that of the top end, so that the center of gravity of the round cushion block is not at the center of the round cushion block, but between the center and the bottom end; as Figure 2 shown, the two axial ends of the round cushion block can be two inclined planes, or one vertical plane and one inclined plane; to improve the stability of the cushion block, the cushion block is preferably a left-right symmetric structure, so that the center of gravity of the cushion block is located in the middle and lower part of the cushion block;

[0042] A round hole 2 is provided in the middle of the cushion block main body 1. The central axis of the round hole 2 coincides with the central axis of the cushion block main body 1. The connection line between the first end and the second end passes through the round hole 2, and the diameter of the round hole 2 is slightly larger than the diameter of the steel bar;

[0043] A through groove 3 is provided on the cushion block main body 1. The through groove 3 is a vertical groove body. The through groove 3 starts from the first end of the round cushion block and ends at the round hole 2. The width of the through groove 3 is slightly larger than the diameter of the steel bar.

[0044] The steel bars enter the round holes 2 through the through grooves 3, so as to be connected and used with the steel bars after binding. Moreover, the round pads automatically adjust under their own gravity, making the first end of the pads located at the bottom end, that is, the open end of the through groove 3 is vertically downward, so that the pads will not break away from the steel bars, achieving a self-stable state, which greatly facilitates the construction of highway engineering.

[0045] Referring to Figure 3 As shown, in some embodiments, a diamond-shaped groove 4 is provided at the outer end of the through groove 3. The narrow end of the diamond-shaped groove 4 is connected to the through groove 3, and the wide end of the diamond-shaped groove 4 is located at the first end of the pad body 1. The width of the wide end of the diamond-shaped groove 4 is greater than the diameter of the steel bar, so as to facilitate the steel bar to enter the through groove 3 and thus facilitate use; an arc chamfer is provided at the outer end of the diamond-shaped groove 4 to avoid scratching and knocking damage caused by sharp corners.

[0046] Referring to Figure 5 As shown, in some embodiments, the self-stable round cake-shaped concrete pads are made of mortar or fine-grained concrete. The pad body 1 includes a steel bar skeleton 5, and concrete 6 is poured on the steel bar skeleton 5.

[0047] Referring to Figure 5 As shown, in some embodiments, the steel bar skeleton 5 includes an inner ring steel bar 51, an outer ring steel bar 52 and connecting steel bars 53;

[0048] Both the inner ring steel bar 51 and the outer ring steel bar 52 are annular steel bars. The inner diameter of the inner ring steel bar 51 is greater than the diameter of the round hole 2, and the outer diameter of the outer ring steel bar 52 is smaller than the diameter of the pad body 1. The inner ring steel bar 51 is arranged in the middle of the outer ring steel bar 52, and the two are concentrically arranged. The inner ring steel bar 51 and the outer ring steel bar 52 are respectively provided with a first notch and a second notch, and the widths of the first notch and the second notch are both greater than the width of the through groove 3;

[0049] The connecting steel bars 53 are vertical steel bars. Two connecting steel bars 53 are arranged in parallel, and the two ends of the connecting steel bars 53 are respectively connected to the ends of the first notch and the second notch.

[0050] In some embodiments, the steel bar skeleton 5 further includes auxiliary rib bars 54, and the auxiliary rib bars 54 are straight steel bars;

[0051] The two ends of the auxiliary rib bars 54 are respectively connected to the inner ring steel bar 51 and the outer ring steel bar 52, and a plurality of auxiliary rib bars 54 are distributed in a divergent manner around the inner ring steel bar 51, so as to improve the strength of the steel bar skeleton 5.

[0052] In some embodiments, the inner ring steel bar 51, the outer ring steel bar 52, the connecting steel bars 53 and the auxiliary rib bars 54 are located in the same plane to form a circular skeleton, and the pad body 1 has a plurality of circular skeletons;

[0053] The steel bar skeleton 5 further includes support rib bars 55;

[0054] There are a plurality of support ribs 55 provided between adjacent circular skeletons. Both ends of the support ribs 55 are respectively connected to the outer ring steel bars 52 of the adjacent circular skeletons. The support ribs 55 are vertically arranged, thereby forming a three-dimensional skeleton;

[0055] The plurality of support ribs 55 are evenly distributed in a ring shape, and the lengths of the plurality of support ribs 55 are the same, making the steel bar skeleton 5 a disc-shaped structure with parallel sides on both sides; the lengths of the plurality of support ribs 55 can also be different. According to the position on the main body 1 of the cushion block, the length of the support rib 55 gradually decreases from the first end to the second end, making the shape of the steel bar skeleton 5 similar to the shape of the main body 1 of the cushion block.

[0056] In some embodiments, the inner ring steel bar 51, the outer ring steel bar 52, the connecting steel bar 53, the auxiliary rib 54 and the support rib 55 are welded together.

[0057] As recorded by the above technical features, the working principle of the concrete cushion block provided by this application in the actual application scenario is as follows:

[0058] According to the diameter of the steel bar, design the steel bar skeleton and the cushion block size, and draw the construction drawings;

[0059] Complete the binding work of the steel bar skeleton 5 according to the construction drawings, and weld the inner ring steel bar 51, the outer ring steel bar 52, the connecting steel bar 53, the auxiliary rib 54 and the support rib 55 together to ensure that the spacing, position and angle of the steel bars meet the design requirements;

[0060] Place the steel bar skeleton 5 in the mold and pour concrete. After solidification, a concrete cushion block is obtained.

[0061] When in use, align the through groove 3 end of the cushion block main body 1 with the steel bar, and insert the cushion block onto the steel bar until the steel bar is completely located in the circular hole 2 at the center of the cushion block; due to the thickened design at the grooved end of the cushion block, the cushion block will automatically adjust under the action of gravity, making the grooved end face downward, achieving a self-stable state.

[0062] Check the position and stability of each cushion block one by one to ensure that each cushion block is correctly installed and stable. Small-angle rotation and offset of the concrete cushion block have no influence on the control of the protective layer. When all the cushion blocks are correctly installed and stable, the side formwork can be installed. The side formwork should be closely attached to the cushion block. Since there is no groove on the side of the cushion block facing the formwork, the cushion block will not fall off. After pouring concrete, the concrete cushion block and the concrete form an integral body.

[0063] The concrete cushion block passed by this application is reasonably designed and has a simple structure. It can be used in connection with the steel bars after binding. Moreover, through the eccentric structure design, after being connected with the steel bars, it can achieve self-stability and will not break away, which greatly facilitates the construction of highway projects.

[0064] Embodiment Two:

[0065] Refer to Figure 5 As shown, in some embodiments, in order to further improve the stability of the connection between the cushion block body 1 and the steel bar, a limiting hole 10 is provided on the through groove 3. The limiting hole 10 is a through hole, the size of the limiting hole 10 is larger than the width of the through groove 3, and a limiting block 7 is inserted into the limiting hole 10. The limiting block 7 can be a concrete structure;

[0066] After the steel bar enters the round hole 2 from the through groove 3, the limiting block 7 is inserted into the limiting hole 10 to block the through groove 3, so that the cushion block body 1 cannot break away from the steel bar.

[0067] In some embodiments, the limiting hole 10 is a circular through hole, the diameter of the limiting hole 10 is larger than the diameter of the round hole 2, and the limiting hole 10 can be tangent to the round hole 2. The limiting block 7 is an insertion rod, which is a concrete column body, and the insertion rod is inserted into the circular through hole; a conical head is provided at the end of the insertion rod, so as to facilitate the insertion of the limiting block 7 into the limiting hole 10.

[0068] Embodiment Three:

[0069] Refer to Figure 6 As shown, in some embodiments, in order to further improve the stability of the connection between the cushion block body 1 and the steel bar, a clamping groove 8 is provided at the first end of the round hole 2. The width of the clamping groove 8 is larger than the width of the through groove 3, and a clamping plate 9 is provided in the clamping groove 8. The clamping plate 9 separates the round hole 2 and the through groove 3;

[0070] The clamping groove 8 can be an arc structure, and the clamping plate 9 is an arc-shaped plate body. After the steel bar enters the round hole 2 from the through groove 3, the arc-shaped plate body is inserted into the clamping groove 8 to block the through groove 3, so that the cushion block body 1 cannot break away from the steel bar. And in order to facilitate the connection with the steel bar, the thickness of the clamping plate 9 matches the thickness of the clamping groove 8.
