Description

A connecting clip for a steel wire mesh insulation board Technical Field

[0001] This utility model belongs to the technical field of reinforced concrete walls, and specifically relates to a connecting clip for a steel wire mesh insulation board. Background Technology

[0002] Precast insulation components consisting of wire mesh and insulation boards are commonly used in reinforced concrete exterior wall insulation systems. However, during on-site construction, the insulation boards may deform or even crack. To enhance the strength of the insulation boards, a common technique involves inserting steel wire rods inside the insulation board and welding one end of the wire rods to the wire mesh to strengthen the board. However, this method requires multiple point connections on both sides of the insulation board to fix the wire rods, resulting in low efficiency, complex operation, and high construction difficulty. To address the aforementioned issues, the technical solution disclosed in patent CN220769869U proposes a thermal break type connector. While this can increase the stability and lifespan of the wall, it still has the following problems: the connector is a hollow structure, which reduces its load-bearing capacity and makes it easy to be flattened or bent, leading to a decrease in its fastening performance; moreover, during conventional construction, concrete needs to be poured on both sides of the insulation board. The above solution can only ensure a firm connection between the insulation board and the concrete on one side of the wire mesh, while neglecting the concrete structure on the other side. This results in an insufficiently tight connection between the insulation board and the concrete structure on the other side, affecting the strength of the wall after construction. Summary of the Invention

[0003] To address the existing technical problems, this utility model proposes a connecting clip for steel wire mesh insulation boards, which solves the problem that current connecting clips affect the strength performance of the wall after construction.

[0004] The purpose of this utility model and the technical problem it solves are achieved by the following technical solution. A connecting clip for a steel wire mesh insulation board, according to this utility model, includes a mesh limiting plate and a hollow connecting rod. One end of the connecting rod has a driving head through the limiting plate, and the other end has a convex structure. The driving head has an axially extending placement groove. The connecting rod has an L-shaped reinforcing rod inside. The long part of the reinforcing rod passes through the driving head into the connecting rod, and its end protrudes from the convex structure. The short part of the reinforcing rod is locked in the placement groove, and the part protruding from the placement groove is tied and fixed to the horizontal or vertical steel wires parallel to each other on the steel wire mesh. Both sides of the mesh limiting plate have V-shaped grooves for locking the horizontal or vertical steel wires on the steel wire mesh, and the mesh limiting plate has fixing holes for the connecting rod to pass through.

[0005] Furthermore, a through hole is provided on the connecting rod near the drive head.

[0006] Furthermore, the drive head has a hexagonal head structure.

[0007] Furthermore, the convex structure consists of multiple sharp teeth arranged circumferentially at the other end of the connecting rod, which can penetrate the insulation board through the sharp teeth.

[0008] Furthermore, a threaded structure is provided axially on the outer wall of the connecting rod near the convex structure.

[0009] Furthermore, the threaded structure includes interconnected large and small threads, with the small threads positioned close to the convex structure.

[0010] Furthermore, the drive head is provided with a socket for the reinforcing rod to pass through, and the inside of the connecting rod is a cylindrical hole. The socket and the cylindrical hole have the same diameter, and the diameter of the socket is greater than or equal to the diameter of the reinforcing rod.

[0011] In summary, this utility model has the following advantages:

[0012] (1) Setting a reinforcing rod inside the connecting rod of the hollow structure can improve the hardness of the connecting rod, improve its load-bearing capacity, prevent it from being flattened or bent, ensure the fastening performance of the connecting rod, and thus improve the strength of the wall.

[0013] (2) The long part of the L-shaped reinforcing rod protrudes from the connecting rod, and when the concrete is poured, the concrete can flow into the interior of the connecting rod through the convex structure and through hole. After solidification, the connecting rod and the reinforcing rod become an integral structure. At the same time, the protruding part of the long rod is wrapped in the concrete, which increases the tensile strength between the connecting rod and the concrete structure on one side, thereby improving the tightness of the connection. The short part of the L-shaped reinforcing rod is tied to the wire mesh. After the concrete solidifies, it strengthens the integrity between the connecting rod, the wire mesh, and the concrete structure on the other side. The connecting rod improves the tensile performance between the insulation board and the concrete structures on both sides, ensuring the strength of the wall after construction.

In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more obvious and understandable, preferred embodiments are given below, and detailed descriptions are provided in conjunction with the accompanying drawings.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and preferred embodiments.

[0020] Please refer to Figures 1-4. A connecting clip for a steel wire mesh insulation board includes a mesh limiting plate 1 and a connecting rod 3 that works in conjunction with the mesh limiting plate 1. The connecting rod 3 has a hollow structure. One end of the connecting rod 3 is connected to a hexagonal head drive head 2 through the limiting plate, and the other end has a convex structure. The convex structure consists of multiple sharp teeth 8 arranged circumferentially at the other end of the connecting rod 3. The connecting rod 3 can penetrate the insulation board through the sharp teeth 8. A through hole 4 is provided on the connecting rod 3 near the drive head 2 to facilitate the flow of concrete into the interior of the connecting rod 3. A threaded structure is provided on the outer wall of the connecting rod 3 near the sharp teeth 8 along the axial direction.

[0021] Both sides of the mesh limiting plate 1 are provided with V-shaped grooves 10 for inserting transverse or longitudinal reinforcing bars on the wire mesh, so that the reinforcing bars can slide in and thus abut against the wire mesh. The mesh limiting plate 1 is provided with fixing holes 9. When the driving tool drives the hexagonal head structure driving head 2 to rotate, the connecting rod 3 passes through the fixing hole 9 and penetrates the insulation board. When the limiting plate and the mesh limiting plate 1 form a stop fit, the driving tool stops rotating. At this time, the connecting rod 3 is inserted into the insulation board, and one end of the convex structure penetrates the insulation board.

[0022] Specifically, the mesh limiting plate 1 and the connecting rod 3 are separate structures. The mesh limiting plate 1 can be placed against the wire mesh first, and then the connecting rod 3 can be passed through the mesh limiting plate 1 and the insulation board in sequence to achieve fixation, which is convenient for installation.

[0023] The drive head 2 is provided with a placement groove 11 extending axially to the upper surface of the limiting plate. The drive head 2 is provided with an insertion hole. The interior of the connecting rod 3 is a cylindrical hole. The diameter of the insertion hole is the same as that of the cylindrical hole, and the diameter of the insertion hole is greater than or equal to the diameter of the reinforcing rod 5. The interior of the connecting rod 3 is provided with an L-shaped reinforcing rod 5. The reinforcing rod 5 can be made of a cylindrical body (such as a steel bar) made of a material with a certain hardness. When the connecting rod 3 penetrates the insulation board and the mesh limiting plate 1 is locked with the wire mesh, the long part of the reinforcing rod 5 passes through the drive head 2 and enters the connecting rod 3, and its end protrudes from the convex structure. At the same time, concrete material fills the interior of the connecting rod 3 through the through hole 4 or the gap between the convex structure and the reinforcing rod 5. The short part of the reinforcing rod 5 is stuck in the placement groove 11, and the part protruding from the placement groove 11 is tied and fixed with the transverse steel bars or longitudinal steel wires parallel to each other on the wire mesh.

[0024] The threaded structure includes a large thread 6 and a small thread 7 that are connected to each other, with the small thread 7 positioned close to the convex structure. The threaded structure can increase the pull-out force and has a self-locking function to prevent the connecting rod 3 from retracting or falling off. In addition, after the threaded structure passes through the insulation board, it can cooperate with the anchor plate to lock and further fix the connecting rod 3, thereby improving the integrity and stability of the wire mesh and the insulation board.

[0025] The working process of a connecting clip for a steel wire mesh insulation board according to this utility model:

[0026] (1) A single layer of wire mesh is provided on one side of the insulation board. The V-groove 10 on both sides of the mesh limiting plate 1 is aligned with the transverse steel bar or longitudinal steel wire of the wire mesh, that is, the mesh limiting plate 1 abuts against the wire mesh.

[0027] (2) Use a driving tool to drive the driving head 2 and the connecting rod 3 to rotate. The connecting rod 3 passes through the fixing hole 9 on the mesh limiting plate 1 and is screwed into the insulation board until the limiting plate and the mesh limiting plate 1 come into contact and stop. At this time, one end of the convex structure of the connecting rod 3 penetrates the insulation board. At the same time, the connecting rod 3 is further locked by the cooperation of the anchoring plate and the small thread 7.

[0028] (3) Use an L-shaped reinforcing rod 5 to pass through the insertion hole of the drive head 2 into the connecting rod 3 until it protrudes from the connecting rod 3. At the same time, the short part of the reinforcing rod 5 is inserted into the placement groove 11 and tied to the wire mesh. Then, concrete is poured on both sides of the insulation board. The concrete on one side of the wire mesh flows into the connecting rod 3 through the through hole 4, and the concrete on the other side flows into the connecting rod 3 through the gap between the convex structure 3 and the reinforcing rod 5. After the concrete solidifies, a stable connection is achieved between the insulation board, the wire mesh, the connecting rod 3 and the concrete on both sides of the insulation board.

[0029] In other embodiments of this utility model, the drive head 2 may also use a hexagonal groove structure instead of a hexagonal head, or other drive heads 2 that match the drive tool may be used.

[0030] In other embodiments of this utility model, the convex structure is not limited to the pointed tooth portion 8, and other convex structures that facilitate penetration of the insulation board may also be used.

[0031] The above description is merely a preferred embodiment of this utility model. Any simple modifications, equivalent changes, and alterations made by those skilled in the art to the above embodiments based on the technical essence of this utility model without departing from the scope of the technical solution of this utility model shall still fall within the scope of the technical solution of this utility model.
