Description

Technical Field

[0001] This utility model relates to the field of building component technology, and in particular to a concrete protective layer reinforcement component. Background Technology

[0002] Concrete spacers are typically placed between the reinforcing cage and the concrete cover during the construction of reinforced concrete structures. They are auxiliary materials used in building engineering to fix the position of the reinforcing bars, ensure the thickness of the concrete cover, prevent the reinforcing bars from shifting during construction, ensure the designed position, and at the same time avoid the reinforcing bars from being exposed and corroding, thus extending the service life of the structure.

[0003] The concrete cover in a building's concrete structure is used to protect the reinforcing steel bars and requires excellent sealing and crack resistance. Currently, adding a reinforcing mesh is commonly used in concrete cover construction to improve crack resistance. However, the mesh can peel off during installation. Using wire binding and adhesives for fixing can lead to reduced or ineffective fixation over time. Using fixing nails may affect the wall's quality and flatness. Furthermore, the lack of connection between the concrete cover and the internal reinforcing cage results in poor overall integrity of the reinforced concrete structure. Improving the overall structural integrity can enhance the quality of the reinforced concrete structure during construction.

[0004] Therefore, in order to improve the crack resistance of the concrete cover and the integrity of the reinforcing cage and the concrete cover, the functionality of the spacer block is considered to transform it into a connector that can meet multiple needs in reinforced concrete structures. Based on the above objectives, a device is designed that uses a multi-functional connector to strengthen the connection with the mesh laying stage in the construction of the concrete cover. At the same time, it can improve the crack resistance of the concrete cover, improve the stability of the mesh and the surface anti-peeling properties, thereby improving the quality of the reinforced concrete structure. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a device for reinforcing the concrete protective layer with a mesh. This device can be used as a reinforcement and support for the steel cage, and can conveniently position the distance between the steel cage and the concrete protective layer, and reinforce the mesh cloth in the concrete protective layer, so that the steel cage structure and the concrete protective layer can achieve a connection effect and improve the overall structure.

[0006] Therefore, this utility model is implemented using the following technical solution: a device for reinforcing concrete protective layer mesh, comprising a steel bar connector, a fixed base and two sets of adjusting rods, one end of which is symmetrically installed on the steel bar connector and the other end is connected to the fixed base. The steel bar connector is installed on the steel bar cage, and the fixed base is set inside the concrete protective layer surface. In use, the adjusting rods can be adjusted in length according to the concrete protective layer, and the mesh cloth is installed on the concrete protective layer surface through the fixed base.

[0007] Furthermore, the fixed base includes a base and a fixing plate. The base is provided with a grid groove, which includes a circular groove and mesh cloth through holes. The mesh cloth through holes are distributed around the circular groove and communicate with the circular groove. The fixing plate is threadedly connected to the circular groove. When installing the mesh cloth, the mesh cloth is embedded in the grid groove, and then the fixing plate is threadedly connected to the circular groove, so that the fixing plate fixes the mesh cloth to the surface of the concrete protective layer.

[0008] Furthermore, the adjusting rod includes a fixed tube and an adjusting tube. One end of the fixed tube is fixedly connected to the steel bar connector, and the other end is threadedly connected to the adjusting tube. The adjusting tube rotates along the thread direction of the fixed tube to adjust the overall length of the adjusting rod.

[0009] Furthermore, the steel bar connector includes a first connector and a second connector. Two adjusting rods are symmetrically fixed on the first connector. The second connector is provided with through holes corresponding to the adjusting rods. The second connector can pass through the through holes to connect with the first connector.

[0010] Furthermore, both the first and second connectors have vertical and horizontal bar grooves inside. When the first and second connectors are installed on the reinforcing cage, the vertical and horizontal bars of the reinforcing cage are respectively inserted into the corresponding vertical and horizontal bar grooves.

[0011] Furthermore, the first connector is provided with four bolt slots, which are symmetrically arranged in pairs on both sides of the first connector. A nut is provided in each bolt slot, and a baffle is provided at the opening of the bolt slot. The second connector is provided with a fixing bolt corresponding to the bolt slot. In use, the fixing bolt is rotated and inserted into the bolt slot to connect and fix the first connector and the second connector.

[0012] Furthermore, the rear end of the fixed base is provided with a slot corresponding to the adjusting rod, and the adjusting rod can be inserted into the slot and welded to the fixed base.

[0013] The beneficial effects of adopting the above technical solution are as follows:

[0014] 1. This device can set the fixing base inside the concrete protective layer. When laying the mesh cloth inside the concrete protective layer, the cross intersection of the mesh cloth is embedded in the mesh groove and installed in the base. The fixing plate is used to fix the mesh cloth. This installation structure makes the mesh cloth and the reinforcing cage connected, which improves the integrity of the concrete protective layer, the mesh cloth and the reinforcing cage structure, strengthens the connection strength of the mesh cloth, prevents the mesh cloth from falling off the concrete protective layer and improves the peel resistance of the mesh cloth.

[0015] 2. The adjusting rod consists of a fixed tube and an adjusting tube. The overall length of the adjusting rod is adjusted via the adjusting tube, allowing it to accommodate different spacings between the concrete cover and the reinforcing cage. This makes the device suitable for projects with varying spacing requirements, resulting in a wide range of applications. Simultaneously, by adjusting the length of the adjusting rod to determine the spacing between the concrete cover and the reinforcing cage, it assists construction personnel in determining the thickness of the reinforced concrete structure, facilitating the construction of the concrete cover.

[0025] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0026] Reference Figure 1-7 As shown, the first embodiment of this utility model provides a device for reinforcing the concrete protective layer with a mesh, including a steel bar connector, a fixed base, and two sets of adjusting rods 7. One end of each set of adjusting rods 7 is symmetrically installed on the steel bar connector, and the other end is connected to the fixed base. The steel bar connector is installed on the steel bar cage, and the fixed base is set inside the surface of the concrete protective layer 8. In use, the adjusting rods 7 can be adjusted in length according to the concrete protective layer 8, and the mesh cloth 9 is installed on the surface of the concrete protective layer 8 through the fixed base.

[0027] The fixed base includes a base 15 and a fixing plate 13. The base 15 has a mesh groove, which includes a circular groove 18 and mesh fabric through holes 14. The mesh fabric through holes 14 are distributed around the circular groove 18 and communicate with it. The fixing plate 13 is threadedly connected to the circular groove 18. When installing the mesh fabric 9, the mesh fabric 9 is embedded in the mesh groove, and then the fixing plate 13 is threadedly connected to the circular groove 18, so that the fixing plate 13 fixes the mesh fabric 9 to the surface of the concrete protective layer 8. Using this structure, the mesh fabric 9 is embedded in the base 15, and the fixing plate 13 limits and fixes the mesh fabric 9, which can strengthen the mesh fabric 9. At the same time, it forms a connection between the mesh fabric 9 and the reinforcing cage structure, improving the stability and peel resistance of the mesh fabric 9. After the fixing plate 13 is screwed into the circular groove 18, the surface of the fixing plate 13 is flush with the surface of the base 15, so there is no problem of the protective layer surface protruding. This can ensure the flatness of the concrete protective layer 8 surface, providing a good reinforcement effect while also facilitating subsequent construction.

[0028] The adjusting rod 7 includes a fixed tube and an adjusting tube. One end of the fixed tube is fixedly connected to the reinforcing bar connector, and the other end is threadedly connected to the adjusting tube. The adjusting tube rotates along the thread direction of the fixed tube to adjust the overall length of the adjusting rod 7. This adjusting rod structure can adjust the length according to the designed distance between the concrete protective layer 8 and the reinforcing cage. It can assist in marking the distance between the reinforcing cage and the concrete protective layer 8 during construction, and at the same time, it facilitates the adjustment of the position of the fixing base, fixing it to the part of the concrete protective layer 8 where the mesh cloth 9 needs to be laid. This allows the fixing base to be embedded in the concrete protective layer surface, achieving the function of fixing the mesh cloth 9 while keeping the wall surface flat.

[0029] The steel bar connector includes a first connector 5 and a second connector 6. The adjusting rod 7 is fixedly connected to both sides of the first connector 5. The second connector 6 has through holes 12 on both sides, through which the second connector 6 can pass the adjusting rod 7 and connect to the first connector 5. This allows for more convenient and accurate docking of the two connectors when assembling the first connector 5 and the second connector 6.

[0030] Both the first connector 5 and the second connector 6 have internal vertical reinforcement grooves 4 and horizontal reinforcement grooves 3. When the first connector 5 and the second connector 6 are installed on the reinforcing cage, the vertical reinforcement 2 and horizontal reinforcement 1 of the reinforcing cage are respectively inserted into the corresponding vertical reinforcement grooves 4 and horizontal reinforcement grooves 3. Both connectors are provided with slots that match the vertical reinforcement 2 and horizontal reinforcement 1 of the reinforcing cage, so that the connectors can be stably and firmly installed at the intersection of the horizontal and vertical reinforcement of the reinforcing cage, preventing the connectors from shifting.

[0031] The two sets of connectors of the steel bar connector are fixedly connected by fixing bolts 11. The first connector 5 is provided with four bolt grooves 10, and a nut 16 is provided in the bolt groove 10. A baffle 17 is provided at the opening of the bolt groove 10. The second connector 6 is provided with fixing bolts 11 corresponding to the bolt grooves 10. In use, the fixing bolts 11 are rotated and inserted into the bolt grooves 10 to connect and fix the first connector 5 and the second connector 6.

[0032] After adopting the above technical solution, once the internal steel reinforcement cage is tied, the steel reinforcement connectors are prepared for installation. The connectors are fixed at the intersection of the horizontal and vertical steel reinforcements using a self-locking structure with horizontal and vertical grooves. First, the first connector 5 is placed at the intersection of the steel reinforcement cage. Then, the vertical and horizontal reinforcements of the steel reinforcement cage are aligned with the corresponding horizontal and vertical grooves of the first connector 5. Next, the second connector 6 is passed through the through hole to the corresponding adjusting rod 7. The second connector 6 is slid along the adjusting rod 7 until it is tightly fitted to the first connector 5. When the two connectors are tightly fitted, the fixing bolt 11 of the second connector 6 is inserted into the bolt groove 10. The fixing bolt 11 is rotated to further penetrate the bolt groove 10, achieving a tight connection between the two connectors. After determining the distance between the concrete protective layer 8 and the steel reinforcement cage, the operator adjusts the length of the adjusting rod 7 according to the distance. The front end of the adjusting rod 7 is inserted into the hole behind the steel reinforcement base and welded. Then, the concrete protective layer 8 is poured. When laying the mesh fabric 9 in the concrete protective layer, the laying position of the mesh fabric 9 is determined by the fixed base extending to the surface of the concrete protective layer 8, and the mesh fabric 9 is aligned with the mesh fabric through holes 14 and laid on the base 15. Then, the fixing plate 13 is installed. After the fixing plate 13 is screwed into the circular groove 18 of the base 15, the surface of the fixing base can remain flat with the wall surface after the mesh fabric 9 is laid, so that the mesh fabric 9 is not easy to peel off from the concrete protective layer 8, improving the stability of the mesh fabric 9 laying. At the same time, this device also serves to connect the mesh fabric 9 with the internal steel cage, so that the mesh fabric 9, the concrete protective layer 8 and the steel cage structure have integrity, thereby improving the quality of the reinforced concrete structure.
