Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of building construction, and specifically to a fixing device for a wire mesh sheet of a floor heating system and a using method thereof. Background Art
[0002] As a low-temperature radiant heating floor, generally an extruded polystyrene foam board is laid at the bottom, and a two-way wire mesh sheet is usually arranged above and below the heat dissipation pipe in the middle, and then a concrete filling layer is poured. The lower wire mesh sheet is used to fix the heat dissipation pipe. The upper wire mesh sheet is used to reduce the cracking of the filling layer caused by the thermal expansion and contraction of the floor heating. However, during the construction of the concrete filling layer, the upper wire mesh sheet always shows problems such as exposed reinforcement. Through analysis and research, it is found that there are two reasons: 1. The flatness of the concrete filling layer is not enough, and the local protection layer of the wire mesh sheet is insufficient, resulting in exposed reinforcement; 2. The wire mesh sheet is not firmly tied, and it is easy to cause warping during the pouring process at the corner parts. The above reasons cause the upper wire mesh sheet to show exposed reinforcement. Summary of the Invention
[0003] The present invention aims to solve the above problems, and thus provides a fixing device for a wire mesh sheet of a floor heating system and a using method thereof to avoid exposed reinforcement.
[0004] To solve the above problems, the present invention adopts the following technical solutions: A fixing device for a wire mesh sheet of a floor heating system includes a positioning component, a connecting device and an adjusting component; The positioning component includes a fixing disk, a vertical rod is arranged in the middle of the top surface of the fixing disk, and a first positioning ring is arranged at the top end of the vertical rod; The connecting device includes a positioning sleeve on one side of the vertical rod, a threaded hole is opened in the middle of the positioning sleeve, and a group of opposite second positioning rings are arranged at the top of the positioning sleeve close to the vertical rod side; The adjusting component includes a screw rod, and a positioning disk is arranged at the top of the screw rod; The positioning sleeve is located on one side of the vertical rod, the first positioning ring is located between the second positioning rings and a positioning rod is inserted through them together, the screw rod passes through the threaded hole of the positioning sleeve and the positioning disk is located above the positioning rod.
[0005] A using method of a fixing device for a wire mesh sheet of a floor heating system includes the following steps: S1: Lay the extruded polystyrene board, and then arrange the wire mesh sheet, and mark the positions where the corners of the wire mesh sheet are easy to warp and expose reinforcement.
[0006] S2: At the marked positions, use the vertical rod to pass through the extruded polystyrene board from bottom to top.
[0007] S3: Construct the reflective film, the lower wire mesh sheet, the heat dissipation pipe and the upper wire mesh sheet. Then, make the second positioning ring of the positioning sleeve opposite to the first positioning ring at the top end of the vertical rod to form a positioning ring group, insert the positioning rod through the positioning ring group together, and tie and fix the upper wire mesh sheet to the positioning rod.
[0008] S4: Determine the floor elevation, and then pass through and adjust the screw rod in the screw holes of the positioning sleeve so that the positioning plate at the top of the screw rod is at the elevation of the surface layer.
[0009] S5: When pouring the concrete filling layer for the floor heating, the construction is carried out with reference to the top of the positioning plate.
[0010] The present invention adopting the above technical solution, compared with the prior art, its prominent features are: Through the cooperation of the positioning component and the connecting device, the binding and fixing of the upper steel wire mesh and the positioning rod are realized, effectively restricting the warping of the mesh caused by the vibration of concrete pouring at the corner parts. The screw rod and the positioning plate of the adjusting component can be adjusted in height according to the floor elevation, so that the top of the positioning plate directly serves as the construction reference surface for the filling layer, accurately controlling the concrete covering thickness and avoiding the problem of exposed reinforcement caused by insufficient protective layer. The positioning sleeve and the vertical rod form a detachable modular structure through the positioning ring group and the positioning rod, which is convenient for rapid assembly and disassembly, reducing the construction interruption time. At the same time, the threaded fit between the screw rod and the positioning sleeve realizes tool-free adjustment, improving the construction efficiency. As a preference, a further technical solution of the present invention is: Furthermore, a number of ventilation holes are opened on the positioning plate. The ventilation holes can discharge the internal air of the filling layer during concrete pouring, avoiding the formation of air pockets between the concrete and the positioning plate due to the aggregation of air bubbles, and improving the density of the filling layer; at the same time, the holes allow a small amount of concrete slurry to penetrate, enhancing the anchoring effect between the positioning plate and the filling layer, preventing the deviation of the elevation reference surface, further ensuring the uniform thickness of the protective layer, and avoiding exposed reinforcement.
[0011] Furthermore, an arc-shaped limiting groove is opened on one side of the positioning sleeve, reducing the construction adjustment time. Its radian matches the outer diameter of the vertical rod, ensuring the coaxiality of the connecting device and the positioning component, avoiding local stress concentration caused by misalignment, and improving the overall stability of the device.
[0012] Furthermore, anti-slip lines are provided on the inner wall of the limiting groove to enhance the friction with the vertical rod, prevent the positioning sleeve from slipping during concrete vibration, ensure the stability of the binding point position of the upper mesh, and reduce the risk of corner warping.
[0013] Furthermore, the same positioning rod passes through at least two positioning ring groups, and simultaneously penetrates more than two positioning ring groups to form a multi-point linkage constraint structure, enhancing the overall stiffness of the mesh and suppressing local deformation; at the same time, reducing the amount of positioning rods used, lowering the material cost, and simplifying the binding operation, avoiding construction misalignment problems caused by multi-point independent fixing, and improving the construction efficiency.

[0016] A fixing device for a floor heating wire mesh sheet includes a positioning component, a connection device and an adjustment component; The positioning component includes a fixed disk 1 with a thickness of 1 mm. In the middle of the top surface of the fixed disk 1, there is a vertical rod 2 welded to the fixed disk 1. The diameter of the vertical rod 2 is 3 mm, and a first positioning ring 3 is provided at the top of the vertical rod 2; The connection device includes a positioning sleeve 4 on one side of the vertical rod 2. The positioning sleeve 4 is a plastic part. A screw hole 5 is provided in the middle of the positioning sleeve 4.

The screw rod 7 passes through the screw hole 5 of the positioning sleeve 4 and the positioning disk 8 is located above the positioning rod 9.
[0017] A usage method of a fixing device for a floor heating wire mesh sheet includes the following steps: S1: Lay the extruded polystyrene board, then layout the wire mesh sheet, and mark the positions where the edges and corners of the wire mesh sheet are prone to warp and expose the ribs.
[0018] S2: At the marked positions, use the vertical rod 2 to pass through the extruded polystyrene board from bottom to top, and the fixed disk 1 is attached to the bottom of the extruded polystyrene board.
[0019] S3: Construct the reflective film, the lower layer wire mesh sheet, the heat dissipation pipe and the upper layer wire mesh sheet. Then, make the second positioning ring 6 of the positioning sleeve 4 opposite to the first positioning ring 3 at the top of the vertical rod 2 to form a positioning ring group. A positioning rod 9 is inserted through the positioning ring group together, and the upper layer wire mesh sheet is tied and fixed to the positioning rod 9.
[0020] S4: Determine the floor elevation, and then pass through and adjust the screw rod 7 in the screw hole 5 of the positioning sleeve 4 so that the positioning disc 8 at the top of the screw rod 7 is at the surface layer elevation.
[0021] S5: When pouring the geothermal concrete filling layer, construct with reference to the top of the positioning disc 8.
[0022] Furthermore, a number of ventilation holes are provided on the positioning disc 8. The ventilation holes can discharge the air inside the filling layer during concrete pouring, avoiding the formation of voids between the concrete and the positioning disc 8 due to the aggregation of air bubbles, and improving the density of the filling layer. At the same time, a small amount of concrete slurry is allowed to penetrate into the holes, enhancing the anchoring effect between the positioning disc 8 and the filling layer, preventing the deviation of the elevation reference surface, further ensuring the uniform thickness of the protective layer, and avoiding exposed reinforcement.
[0023] Furthermore, an arc-shaped limiting groove is provided on one side of the positioning sleeve 4, reducing the construction adjustment time.

[0025] Furthermore, the same positioning rod 9 passes through at least two positioning ring groups, and simultaneously penetrates through more than two positioning ring groups to form a multi-point linkage constraint structure, enhancing the overall stiffness of the mesh and suppressing local deformation. At the same time, the amount of the positioning rod 9 is reduced, the material cost is lowered, and the binding operation is simplified, avoiding construction misalignment problems caused by multi-point independent fixation, and improving the construction efficiency.
[0026] Through the cooperation of the positioning component and the connecting device, the binding and fixing of the upper layer steel wire mesh and the positioning rod 9 are realized, effectively restricting the warping of the mesh at the corner parts caused by the vibration of concrete pouring. The screw rod 7 and the positioning disc 8 of the adjusting component can be adjusted in height according to the floor elevation, making the top of the positioning disc 8 directly serve as the construction reference surface of the filling layer, accurately controlling the concrete covering thickness, and avoiding the problem of exposed reinforcement caused by insufficient protective layer. The positioning sleeve 4 and the vertical rod 2 form a detachable modular structure through the positioning ring group and the positioning rod 9, which is convenient for rapid assembly and disassembly, reducing the construction interruption time. At the same time, the threaded cooperation between the screw rod 7 and the positioning sleeve 4 realizes tool-free adjustment, improving the construction efficiency.
