Description

Technical Field

[0001] This utility model relates to the field of wire mesh hanging device technology, and in particular to a rapid wire mesh hanging device for planting rebar on a concrete base. Background Technology

[0002] In the field of construction engineering, concrete structures, as a widely used building form, directly affect the safety and service life of buildings through their stability and durability. Over long-term use, concrete surfaces are affected by various factors, such as environmental erosion and load-bearing, leading to a decline in structural performance. Therefore, reinforcement of concrete surfaces is essential. Rebar and wire mesh reinforcement is a commonly used method, which involves embedding reinforcing bars and hanging wire mesh on the concrete surface to enhance its load-bearing capacity and crack resistance. However, with existing wire mesh installations, the different material properties of the wire mesh and the concrete surface cause variations in thermal expansion and contraction due to temperature changes, resulting in localized stress concentration between them. This stress concentration initially causes bulging on the wall surface, and over time, the bulging worsens, eventually leading to wall detachment. This not only seriously threatens the safety of the building structure but also significantly increases the cost of later repairs and renovations, causing considerable trouble for building maintenance and management. Therefore, this utility model proposes a rapid rebar and wire mesh installation device for concrete surfaces. Utility Model Content

[0003] The purpose of this invention is to address the problem in the background technology where, due to changes in ambient temperature, the different material properties of the wire mesh and the concrete substrate lead to varying degrees of thermal expansion and contraction, resulting in localized stress concentration between the wire mesh and the concrete substrate. This stress concentration initially causes bulging on the wall surface, and the bulging worsens over time, eventually leading to wall detachment. This not only seriously threatens the safety of the building structure but also significantly increases the cost of subsequent repairs and renovations, causing considerable difficulties for building maintenance and management. The invention proposes a rapid wire mesh installation device for reinforcing bars on a concrete substrate.

[0004] The technical solution of this utility model is as follows: a rapid rebar and wire mesh hanging device on a concrete base surface, comprising: multiple rebars embedded in the concrete base surface, with galvanized steel wire mesh for reinforcing the concrete base surface hanging on the rebars; a limiting component disposed on the rebars for limiting and fixing the galvanized steel wire mesh, the limiting component including a first limiting plate and a second limiting plate, the first limiting plate and the second limiting plate being cross-arranged, a limiting bolt threaded through the intersection of the first limiting plate and the second limiting plate, guide grooves respectively opened at both ends of the first limiting plate and the second limiting plate, a slider being slidably disposed inside the guide groove, a connecting sleeve block being fixedly connected to one end of the slider, a spring being fixedly connected to the other end of the slider, one end of the spring being fixedly connected to the inner wall of the guide groove, a high-strength wear-resistant layer being laid on the outer wall of the rebars, and a concrete layer being laid on the outer side of the high-strength wear-resistant layer.

[0005] Optionally, the outer wall of the rebar is provided with a slot.

[0006] Optionally, steel fibers are added to the interior of the high-strength wear-resistant layer.

[0007] Optionally, a groove is provided on one side of the first limiting plate.

[0008] Optionally, the slider and the connecting sleeve are integrally formed.

[0009] In summary, this application includes at least one of the following beneficial technical effects:

[0010] This utility model uses the first limiting plate, the second limiting plate, the limiting bolt, the guide groove, the slider, the connecting sleeve block, and the spring in the limiting assembly to stably fix the galvanized steel wire mesh, making it tightly adhere to the concrete base surface. This avoids the stress caused by the difference in thermal expansion and contraction between the steel wire mesh and the concrete base surface due to temperature changes, thereby reducing the occurrence of wall bulging and effectively ensuring the safety of the building structure.

[0011] Furthermore, this utility model, by creating grooves on the rebar and using springs and connecting blocks, can stably limit the galvanized steel wire mesh. At the same time, by pouring a high-strength wear-resistant layer inside and adding steel fiber wires, it reduces the occurrence of wall detachment, thereby reducing the frequency of later building maintenance and rectification, avoiding potential hazards to internal building facilities and personnel caused by wall detachment, reducing the burden of building maintenance and management, and lowering the overall maintenance cost.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0025] like Figures 1 to 3 As shown, the present invention proposes a rapid rebar and wire mesh hanging device for concrete base surface, comprising: multiple rebars 1 embedded in the concrete base surface, wherein the rebars 1 are equidistantly arranged, and galvanized steel wire mesh 2 for reinforcing the concrete base surface is hung on the rebars 1, which enables the galvanized steel wire mesh 2 to be stably hung on the concrete base surface; a limiting component 3 set on the rebars 1 for limiting and fixing the galvanized steel wire mesh 2, which can limit the galvanized steel wire mesh 2 and make it tightly attached to the concrete base surface; a high-strength wear-resistant layer 4 is laid on the outer wall of the rebars 1, and a concrete layer 5 is laid on the outside of the high-strength wear-resistant layer 4 to increase the crack resistance and durability of the concrete base surface.

[0026] like Figure 3 and Figure 4 As shown, the limiting component 3 includes a first limiting plate 31 and a second limiting plate 32. The first limiting plate 31 and the second limiting plate 32 are arranged crosswise. A limiting bolt 33 is threaded through the intersection of the first limiting plate 31 and the second limiting plate 32, which can adjust the angle of the first limiting plate 31 and the second limiting plate 32 to make them stably connected with the anchor 1. Guide grooves 34 are respectively opened at both ends of the first limiting plate 31 and the second limiting plate 32. A slider 35 is slidably arranged inside the guide groove 34 to guide the slider 35. A connecting sleeve block 36 is fixedly connected to one end of the slider 35, so that the slider 35 drives the connecting sleeve block 36 to move stably. A spring 37 is fixedly connected to the other end of the slider 35. One end of the spring 37 is fixedly connected to the inner wall of the guide groove 34 to provide tension to the connecting sleeve block 36, thereby making it stably connected with the anchor 1.

[0027] Furthermore, the outer wall of the rebar 1 is provided with a slot 6, which enables the connecting sleeve 36 to be stably engaged with it, ensuring the stability of the galvanized steel wire mesh 2.

[0028] Secondly, steel fiber filaments are added to the interior of the high-strength wear-resistant layer 4 to increase its durability and improve its service life.

[0029] Furthermore, a groove 7 is provided on one side of the first limiting plate 31 to facilitate the storage of the adjusting cap at one end of the limiting bolt 33, preventing it from protruding on the concrete base surface.

[0030] In addition, the slider 35 and the connecting sleeve 36 are integrally formed, which increases the stability of the structure and thus improves its service life.

[0031] In this embodiment, multiple reinforcing bars 1 are embedded in the concrete base surface, and galvanized steel wire mesh 2 for reinforcing the concrete base surface is hung on the reinforcing bars 1.

[0032] By loosening the limiting bolt 33, the first limiting plate 31 and the second limiting plate 32 are rotated on the limiting bolt 33, and the first limiting plate 31 and the second limiting plate 32 are pulled to move the connecting sleeve 36 so that it can be engaged with the rebar 1.

[0033] Pulling the connecting sleeve 36 causes the slider 35 to slide stably inside the guide groove 34, allowing the connecting sleeve 36 to be stably fitted onto the rebar 1. Under the elastic force of the spring 37, the connecting sleeve 36 is tightly locked into the groove 6 on the outer wall of the rebar 1, pressing the galvanized steel wire mesh 2 tightly against the concrete base surface. This effectively avoids the stress caused by the difference in thermal expansion and contraction between the steel wire mesh and the concrete base surface due to temperature changes, thereby reducing the occurrence of wall bulging.

[0034] Finally, a high-strength wear-resistant layer 4 is applied to the concrete base surface, and a concrete layer 5 is laid on the outside of the applied high-strength wear-resistant layer 4 to allow it to solidify, providing stable support for the building structure, effectively ensuring the safety of the building structure, reducing the frequency of later building maintenance and rectification, alleviating the burden of building maintenance and management, and reducing overall maintenance costs.

[0035] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
