Description

Technical Field

[0001] The present application relates to the technical field of thermal insulation board connectors, and particularly to a broken-bridge thermal insulation board connector. Background Art

[0002] During the construction of building thermal insulation boards, it is often necessary to use thermal insulation board connectors to connect the thermal insulation boards and the concrete wall. Traditional integrated thermal insulation board connectors have a serious thermal bridge effect, which reduces the thermal performance of the wall and shortens the wall life in practical engineering applications.

[0003] Currently, the broken-bridge thermal insulation board connector includes a first metal screw rod, a second metal screw rod, and a broken-bridge connector. The outer walls of the first metal screw rod and the second metal screw rod are both helically arranged. The first metal screw rod and the second metal screw rod are connected by the broken-bridge connector. The existing wall includes a thermal insulation board and an inner leaf wall, and the inner leaf wall is formed by pouring concrete. Pre-drilled holes are provided on the outer walls of the thermal insulation board and the inner leaf wall. When installing the broken-bridge thermal insulation board connector, the broken-bridge thermal insulation board connector is helically installed into the pre-drilled holes. The first metal screw rod is fixed to the inner wall of the thermal insulation board, and the second metal screw rod is fixed to the inner wall of the inner leaf wall. Subsequently, concrete is covered on the outer wall of the thermal insulation board. The broken-bridge connector often uses an engineering plastic material with a low thermal conductivity, reducing the thermal bridge effect of the broken-bridge thermal insulation board connector.

[0004] During the above process of installing the second metal screw rod, the second metal screw rod is helically installed into the inner wall of the inner leaf wall, and the thread on the outer wall of the second metal screw rod destroys the concrete on the inner wall of the inner leaf wall, resulting in a gap between the outer wall of the second metal screw rod and the inner wall of the inner leaf wall. The connection between the broken-bridge thermal insulation board connector and the wall is loose, and there is room for improvement. Summary of the Utility Model

[0005] In order to make the connection between the broken-bridge thermal insulation board connector and the wall more firm, the present application provides a broken-bridge thermal insulation board connector.

[0006] A broken-bridge thermal insulation board connector provided by the present application adopts the following technical solutions:

[0007] A broken-bridge thermal insulation board connector includes:

[0008] A fixing component, including a positioning member, and the positioning member is arranged on the inner wall of the thermal insulation board;

[0009] A connecting component, including a connecting rod and a connecting pipe, and the connecting pipe is fixed to the end of the connecting rod;

[0010] The anchoring assembly includes an extrusion rod fixed to the inner wall of the connecting pipe, a fixing block threadedly connected to one end of the extrusion rod away from the connecting pipe, and an expansion pipe threadedly connected to the outer wall of the extrusion rod. The side wall of the expansion pipe abuts against the side wall of the fixing block, and the side wall of the extrusion rod can abut against the side wall of the expansion pipe on the side away from the fixing block.

[0011] By adopting the above technical solution, when installing the broken-bridge thermal insulation board connector, the broken-bridge thermal insulation board connector is installed on the inner wall of the pre-drilled hole. At this time, the extrusion rod, the fixing block and the expansion pipe are located on the inner wall of the inner leaf wall, and the positioning member is located inside the thermal insulation board. The worker controls the positioning member to slide in the pre-drilled hole towards the inner leaf wall. Under the action of the positioning member, the connecting rod drives the connecting pipe to slide in the pre-drilled hole, so that the extrusion rod and the fixing block jointly extrude the expansion pipe. After the side wall of the expansion pipe expands, it abuts against the inner wall of the inner leaf wall, making the connection between the broken-bridge thermal insulation board connector and the wall more firm.

[0012] Optionally, the extrusion rod includes an extrusion block and a threaded rod. The extrusion block is fixed to one end of the connecting pipe away from the connecting rod, and the threaded rod is fixed to one end of the extrusion block away from the connecting rod. The diameter of the extrusion block is larger than the inner diameter of the expansion pipe.

[0013] By adopting the above technical solution, when installing the broken-bridge thermal insulation board connector, the threaded rod rotates on the inner wall of the expansion pipe, and then the side wall of the extrusion block abuts against the side wall of the threaded rod. Under the action of the extrusion block and the fixing block, the side wall of the expansion pipe expands and deforms, and the side wall of the expansion pipe abuts against the inner wall of the inner leaf wall. This process increases the stability of the expansion process of the expansion pipe.

[0014] Optionally, a clamping groove is formed on the side wall of the extrusion block, and a clamping block is fixed to the inner wall of the connecting pipe near one end of the fixing block. The inner wall of the clamping groove is clamped with the outer wall of the clamping block.

[0015] By adopting the above technical solution, under the action of the clamping groove and the clamping block, the axial position of the extrusion block is fixed on the threaded rod, increasing the stability of the extrusion block and the threaded rod during operation.

[0016] Optionally, the positioning member includes a positioning rod, a fixing pipe and a positioning disc. The side wall of the positioning rod is fixed to the fixing pipe, the positioning disc is fixed to one end of the fixing pipe away from the connecting rod, and one end of the connecting rod near the positioning rod is fixedly connected to the inner wall of the fixing pipe.

[0017] By adopting the above technical solution, when installing the broken-bridge thermal insulation board connector, the positioning rod is located inside the thermal insulation board. The positioning rod and the connecting rod are connected under the action of the fixing pipe. The worker controls the connecting rod to slide on the inner wall of the pre-drilled hole through the positioning rod, so as to fix the broken-bridge thermal insulation board connector on the inner wall of the pre-drilled hole.

[0018] Optionally, the outer wall of the connecting rod is spirally arranged. The connecting rod is threadedly fixed to one end of the fixed pipe close to the fixed block, and the connecting rod is threadedly fixed to the inner wall of the connecting pipe far from the fixed block.

[0019] By adopting the above technical solution, when installing the broken-bridge thermal insulation board connector, the staff screws the broken-bridge thermal insulation board connector into the pre-drilled hole in a spiral manner. The spirally arranged connecting rod facilitates the installation of the broken-bridge thermal insulation board connector by the staff.

[0020] Optionally, a protective sleeve is fixed to the side wall of the fixed pipe. The side wall of the positioning disc is fixed to the inner wall of the protective sleeve, and the side wall of the protective sleeve abuts against the inner wall of the thermal insulation board.

[0021] By adopting the above technical solution, the setting of the protective sleeve reduces the corrosion of the fixed pipe by external rainwater and increases the service life of the broken-bridge thermal insulation board connector.

[0022] Optionally, a plurality of penetration holes are formed in the side wall of the protective sleeve, and the penetration holes are close to the positioning disc.

[0023] By adopting the above technical solution, when covering the outer layer of the thermal insulation board with concrete, the concrete flows through the penetration holes and fills the gap between the broken-bridge thermal insulation board connector and the thermal insulation board, increasing the fixing effect of the broken-bridge thermal insulation board connector.

[0024] Optionally, fixing holes are formed in the side wall of the expansion tube, abutting blocks are fixed to the side wall of the fixed block, and the abutting blocks are clamped with the inner walls of the fixing holes.

[0025] By adopting the above technical solution, the fixed block is fixed in the fixing hole through the abutting block, reducing the slippage of the fixed block inside the expansion tube and increasing the stability of the broken-bridge thermal insulation board connector during operation.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. When installing the broken-bridge thermal insulation board connector, the broken-bridge thermal insulation board connector slides on the inner wall of the pre-drilled hole. At this time, the expansion tube is located on the inner wall of the inner leaf wall, and the positioning member is located on the inner wall of the thermal insulation board. The staff controls the positioning member to slide on the inner wall of the pre-drilled hole towards the inner leaf wall direction. The positioning member drives the extrusion rod to slide. Under the action of the extrusion rod and the fixed block, the expansion tube is compressed. After the outer wall of the expansion tube expands, it abuts against the inner wall of the inner leaf wall, making the connection between the broken-bridge thermal insulation board connector and the wall more firm.

[0028] 2. When covering the outer wall of the insulation board with concrete, the concrete flows into the gap between the bridge-type insulation board connector and the insulation board through the penetration holes, increasing the contact area between the bridge-type insulation board connector and the insulation board and enhancing the anchoring effect of the bridge-type insulation board connector.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The following Figures 1-3 further describes the present application in detail.

[0034] An embodiment of the present application discloses a bridge-type insulation board connector.

[0035] Referring to Figure 1 , a bridge-type insulation board connector includes a fixing assembly 1, a connecting assembly 2 and an anchoring assembly 3. The fixing assembly 1 includes a positioning member 11 and a protective sleeve 12. In the embodiment of the present application, the protective sleeve 12 is preferably an engineering plastic wrapping layer, and the setting of the protective sleeve 12 reduces the corrosion effect of external rainwater on the bridge-type insulation board connector.

[0036] The positioning member 11 includes a positioning rod 111, a fixing pipe 112 clamped on the outer wall of the positioning rod 111, and a positioning disc 113 fixed to one end of the fixing pipe 112 away from the anchoring assembly 3. The inner wall of the fixing pipe 112 abuts against the outer wall of the positioning rod 111, the inner wall of the positioning disc 113 abuts against the outer wall of the positioning rod 111, and the outer walls of the fixing pipe 112 and the positioning disc 113 both abut against the inner wall of the protective sleeve 12.

[0037] The connecting component 2 includes a connecting rod 21 and a connecting pipe 22. One end of the connecting rod 21 is fixed to the inner wall of the fixed pipe 112, and the other end of the connecting rod 21 is fixed to the inner wall of the connecting pipe 22. The side wall of the connecting rod 21 is helically arranged, and both the fixed pipe 112 and the connecting pipe 22 are threadedly fixed to the connecting rod 21. When installing the broken bridge type thermal insulation board connecting piece, this setting simplifies the installation process of the broken bridge type thermal insulation board connecting piece.

[0038] Reference Figure 1 With Figure 2 , the anchoring component 3 includes a pressing rod 31, an expansion pipe 33 and a fixing block 32. The pressing rod 31 includes a pressing block 311 clamped on the inner wall of the connecting pipe 22 and a threaded rod 312 integrally fixed to one end of the pressing block 311 away from the connecting rod 21. Both the expansion pipe 33 and the fixing block 32 are threadedly connected to the threaded rod 312. The expansion pipe 33 is located near the pressing block 311, and the fixing block 32 is located away from the pressing block 311.

[0039] When installing the broken bridge type thermal insulation board connecting piece, the connecting rod 21 drives the pressing block 311 to slide on the inner wall of the inner leaf wall. At this time, the fixing block 32 rotates on the side wall of the threaded rod 312, and the side wall of the fixing block 32 approaches the pressing block 311. The expansion pipe 33 expands under the action of the fixing block 32 and the pressing block 311, and the outer wall of the expansion pipe 33 abuts against the inner wall of the inner leaf wall, making the connection between the broken bridge type thermal insulation board connecting piece and the wall tight.

[0040] A clamping groove 4 is formed on the side wall of the pressing block 311, and a clamping block 5 is fixed to the inner wall of the connecting pipe 22. Before installing the broken bridge type thermal insulation board connecting piece, the outer wall of the clamping block 5 abuts against the inner wall of the clamping groove 4, reducing the possibility of the pressing block 311 sliding in the direction of the threaded rod 312, increasing the stability of the pressing block 311 in the connecting pipe 22, and making the working process of the broken bridge type thermal insulation board connecting piece stable.

[0041] Reference Figure 2 , a fixing hole 6 is formed on the side wall of the expansion pipe 33, and the fixing hole 6 penetrates the inner wall and the outer wall of the expansion pipe 33. A butting block 7 is fixed to the side wall of the fixing block 32, and the butting block 7 cooperates with the fixing hole 6. Before installing the broken bridge type thermal insulation board connecting piece, the side wall of the butting block 7 abuts against the inner wall of the fixing hole 6. Under the action of the butting block 7, the sliding of the fixing block 32 in the axial direction of the threaded rod 312 is reduced, increasing the stability of the broken bridge type thermal insulation board connecting piece during operation.

[0042] Reference Figure 3, a plurality of penetration holes 8 are provided on the side wall of the protective sleeve 12. In the embodiment of the present application, preferably four penetration holes 8 are provided, and the penetration holes 8 are evenly provided on the outer wall of the protective sleeve 12. When installing the broken-bridge thermal insulation board connector, the concrete flows through the penetration holes 8 to the gap between the broken-bridge thermal insulation board connector and the thermal insulation board, increasing the contact area between the broken-bridge thermal insulation board connector and the thermal insulation board, making the fixation of the broken-bridge thermal insulation board connector on the side wall of the thermal insulation wall more stable.

[0043] The implementation principle of a broken-bridge thermal insulation board connector in the embodiment of the present application is as follows: when installing the broken-bridge thermal insulation board connector, the broken-bridge thermal insulation board connector is installed on the inner wall of the pre-drilled hole 9. At this time, the expansion tube 33 is close to the inner leaf wall, and the positioning rod 111 is close to the thermal insulation board. The staff controls the rotation of the positioning rod 111, and the positioning rod 111 drives the connecting rod 21 to rotate. Under the action of the connecting tube 22, the extrusion block 311 drives the threaded rod 312 to rotate, and the fixing block 32 approaches the extrusion block 311. Subsequently, the side walls of both the extrusion block 311 and the fixing block 32 abut against the side wall of the expansion tube 33, and the expansion tube 33 expands under the extrusion of the extrusion block 311 and the fixing block 32. The outer wall of the expansion tube 33 abuts against the inner wall of the inner leaf wall, making the connection between the broken-bridge thermal insulation board connector and the wall more firm.

[0044] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
