Description

Technical Field

[0001] This utility model relates to a metal snap-on mortar pad, belonging to the field of building construction technology. Background Technology

[0002] In the field of construction engineering, concrete spacers play an indispensable role as key materials for ensuring the thickness of the protective layer of reinforced concrete structures and ensuring the quality of reinforced concrete structures. Their core function is to accurately position and effectively support the reinforcing bars, prevent the reinforcing bars from shifting or deforming during the pouring process, thereby ensuring the bond strength of the concrete to the reinforcing bars and avoiding a series of quality problems such as steel bar corrosion, concrete cracking, and reduced structural bearing capacity caused by the protective layer being too thin or too thick.

[0003] Currently, the G-type mortar spacers commonly used in the market are typically designed with a single "G" shape. The traditional installation and fixing process for G-type spacers is quite cumbersome, and their stability often relies on manual operation by construction workers. This requires multiple wrapping, binding, and tightening of thin wire or binding wire around the spacer and reinforcing bars. This additional step not only significantly reduces the efficiency of spacer installation and slows down the overall construction progress, but also greatly increases the labor intensity and complexity for workers. Especially in complex joints with dense reinforcing bars and limited operating space, the installation difficulty increases exponentially, thus necessitating an improvement. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model designs a metal snap-on mortar pad, which can snap onto the reinforcing bar during installation, thereby increasing the stability of the connection and avoiding cumbersome installation steps.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A metal snap-fit ​​mortar pad includes a G-shaped block, wherein the G-shaped block includes a horizontal rectangular segment, an arc segment and a vertical rectangular segment connected in sequence, the vertical rectangular segment is perpendicular to the horizontal rectangular segment and an opening is formed between the vertical rectangular segment and the horizontal rectangular segment, and a metal spring sheet is fixedly inserted into the arc segment inside the opening.

[0006] Furthermore, the metal spring sheet is positioned at the middle of the arc-shaped segment in the thickness direction.

[0007] Furthermore, the metal spring sheet is a rectangular spring sheet.

[0008] Furthermore, the metal spring sheet is an arched spring sheet, which includes a first arc-shaped sheet, a second arc-shaped sheet, and a third arc-shaped sheet connected in sequence. The bending direction of the second arc-shaped sheet is opposite to the bending direction of the first arc-shaped sheet and the third arc-shaped sheet.

[0009] Compared with the prior art, this utility model has the following features and beneficial effects: This invention achieves an automatic clamping function by embedding a metal spring plate in the G-block. During construction, the steel bar only needs to be aligned with the opening and pressed into place to complete the installation, completely eliminating the tedious wire wrapping, binding and tightening steps in the traditional method. This makes the installation process extremely fast, especially in the construction of large areas and high-density steel bars, which can greatly improve the laying efficiency of the pad block and effectively speed up the overall construction progress.

[0012] The present invention will now be described in more detail with reference to the embodiments.

[0013] Example 1 like Figures 1 to 2 As shown, the metal snap-fit ​​mortar pad of this embodiment includes a G-type block 1, which is formed by casting cement mortar with a strength of M30 or higher.

[0014] Specifically, the G-type block 1 includes a horizontal rectangular segment 104, an arc segment 102, and a vertical rectangular segment 103 connected in sequence.

[0015] A vertical rectangular segment 103 is set perpendicular to a horizontal rectangular segment 104, and an opening 101 is formed between the vertical rectangular segment 103 and the horizontal rectangular segment 104.

[0016] A metal spring sheet 2 is fixedly inserted into the arc-shaped segment 102 inside the opening 101. The metal spring sheet 2 has good elastic deformation and recovery performance.

[0017] In this embodiment, the metal spring sheet 2 is a rectangular spring sheet 201, and the length of the rectangular spring sheet 201 is 26mm. The length of the rectangular spring sheet 201 inserted into the arc segment 102 is 1 / 2 to 1 / 3 of the total length of the rectangular spring sheet 201. This ensures that the rectangular spring sheet 201 will not come out and can also effectively clamp the reinforcing bar inserted into the opening 101.

[0018] It should be noted that the length of the rectangular spring 201 is the distance between the end of the rectangular spring 201 insertion end and the end of the rectangular spring 201 extension end.

[0019] Furthermore, the metal spring sheet 2 is positioned at the middle of the arc segment 102 in the thickness direction, which allows the reaction force of the metal spring sheet 2 to be distributed more evenly, avoiding local high stress points and greatly improving the durability and reliability of the pad.

[0020] Example 2 like Figures 3 to 5 As shown, the metal snap-on mortar pad of this embodiment is otherwise the same as that of Embodiment 1, except that the metal spring sheet 2 is an arched spring sheet 202.

[0021] Specifically, the arched spring piece 202 includes a first arc-shaped piece 2021, a second arc-shaped piece 2022 and a third arc-shaped piece 2023 connected in sequence, and the bending direction of the second arc-shaped piece 2022 is opposite to the bending direction of the first arc-shaped piece 2021 and the third arc-shaped piece 2023.

[0022] In this embodiment, the arched elastic piece 202, through its multi-segment arc design, namely the first arc piece 2021, the second arc piece 2022, and the third arc piece 2023, can provide greater deformation and softer elasticity, adapting to steel bars of different diameters and providing a better clamping effect.

[0023] The working principle of this utility model is as follows: During installation, the reinforcing bar is pressed into the G-block 1 through the opening 101. During this process, the reinforcing bar will compress the metal spring plate 2, causing it to undergo elastic deformation. With the help of the elastic force of the metal spring plate 2 to restore its original shape, it will continuously and tightly press against the surface of the reinforcing bar, thereby generating sufficient friction to firmly lock the reinforcing bar in the G-block 1, achieving a self-locking function without any additional binding or fixing operations.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
