Description

Technical Field

[0001] This utility model relates to the technical field of bridge concrete pad blocks, and in particular to a concrete pad block. Background Technology

[0002] When pouring concrete for existing bridges and immersed tunnels, it is necessary to limit the spacing between the reinforcing bars and the formwork to ensure the concrete thickness of the reinforcing bars in the bridge. Therefore, it is necessary to fix concrete spacers to the reinforcing bars to maintain the spacing between them and the formwork. However, existing concrete spacers have many contact points with the formwork due to the presence of positioning points on their surface. After pouring concrete, many of these positioning points are exposed, resulting in poor bonding between the concrete and the spacers. In addition, existing concrete spacers require steel wire to be fixed to the reinforcing bars, which makes fixing cumbersome.

[0003] Therefore, improvements to existing technologies are still needed. Utility Model Content

[0004] The purpose of this utility model is to provide a concrete pad block, which aims to solve the technical problems of concrete pad blocks used to position the distance between the formwork and the reinforcing bars and to play a protective role, but the pad blocks are easily visible after demolding, resulting in an unsightly appearance of the bridge, and the pad blocks do not bond well with the grout, and there are also problems with fixing them.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a concrete pad block, comprising: a pad block body, wherein both ends of the pad block body are respectively provided with protruding positioning portions, and both ends of the pad block body are also provided with slots for binding the pad block body to the reinforcing bars; the pad block body is also provided with anti-slip textures between the protruding positioning portions.

[0006] The concrete pad block, wherein the slot is formed by the recess between the two end ends of the pad block body and the protruding positioning part.

[0007] The concrete pad block, wherein the height of the protruding positioning portion is greater than the height of the edge end.

[0008] The concrete pad block, wherein the highest point of the protruding positioning part is a line.

[0009] Beneficial effects: This utility model remedies the shortcomings of the original pad block in avoiding leaving scars on the building by setting protruding positioning parts at both ends of the pad block body, making the exterior of the building more aesthetically pleasing; it not only achieves positioning, but also has less exposed positioning parts than the traditional pad block, so the outer surface of the bridge is more beautiful; and the use of steel wire binding through the slot and the use of anti-slip texture allows the pad block to better integrate and fix with the concrete grout, saving labor and time.

[0011] Figure 2 This is a perspective view of the present invention from another angle. Detailed Implementation

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer and more explicit, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0013] like Figure 1 As shown, the existing concrete pad 100 is positioned by setting corrugated protrusions 200 on the surface and positioning it with the template through the corrugated protrusions. However, due to the large number of corrugated protrusions and the fact that multiple protrusions can be clearly seen after the concrete is poured, the bridge surface is not aesthetically pleasing. In addition, the concrete filling the groove between the corrugated protrusions is prone to falling off, and the bonding effect between the pad and the concrete is poor. The concrete pad 100 is also provided with through holes 300 for steel wires to pass through.

[0014] like Figure 2 As shown, this utility model discloses a concrete pad block, which includes: a pad block body 1, with protruding positioning parts 2 respectively provided at both ends of the pad block body 1, and slots 3 for binding the pad block body to a steel bar 1 at both ends of the pad block body 1; and anti-slip texture 4 provided between the protruding positioning parts 2 of the pad block body 1.

[0015] This invention features raised positioning parts at both ends of the pad block body, thus requiring only two positioning positions. This not only achieves the desired spacing between the positioning template and the reinforcing bars but also reduces the number of protruding positioning parts after concrete pouring, resulting in a more aesthetically pleasing bridge surface. Furthermore, the use of steel wire clamps to secure the pad block's ends to the reinforcing bars within the slots makes installation and fixing the pad block simple and convenient. Additionally, the design of anti-slip stripes between the raised positioning parts, rather than the existing grooves between wavy protrusions, allows for better bonding and fixation with the concrete.

[0016] Specifically, the slot 3 is formed by the recess between the two end portions 5 of the pad body 1 and the protruding positioning part 2, so the slots can facilitate the binding of steel wires without affecting the positioning function of the protruding positioning part.

[0017] Specifically, the height of the protruding positioning part 2 is greater than the height of the edge end part 5.

[0018] Specifically, the highest point of the raised positioning part 2 is a line, so after the concrete is poured, the exposed part of the raised positioning part is only a line, which is basically invisible, making the surface of the bridge more beautiful.

[0019] This invention overcomes the shortcomings of traditional pad blocks in avoiding leaving scars on buildings by setting protruding positioning parts at both ends of the pad block body, making the exterior of the building more aesthetically pleasing; it not only achieves positioning but also exposes less of the positioning part compared to traditional pad blocks, thus making the outer surface of the bridge more beautiful; and by using steel wire binding through a slot and using anti-slip texture, the pad block can better integrate and fix with the concrete grout, saving labor and time.

[0020] The above are merely preferred embodiments of this utility model, and should not be construed as limiting the scope of this utility model. It should be noted that for those skilled in the art, any modifications or equivalent substitutions to the technical solution of this utility model without creative effort do not depart from the protection scope of this utility model.
