Description

Technical Field

[0001] The present application relates to the technical field of building connectors, and in particular to a thermal insulation wall connector. Background Art

[0002] Insulation wall panels are a commonly used building material in concrete buildings, especially medium and high-rise buildings. The insulation wall is composed of concrete walls and insulation wall panels, which need to be connected and fixed by connectors.

[0003] The existing insulation wall connector includes a threaded column, a sleeve integrally fixed to one end of the threaded column, and a rivet plate integrally fixed to one end of the sleeve away from the threaded column. Before fixing the insulation board, holes are pre-drilled on the side walls of the insulation board and the concrete wall, and the insulation wall connector is screwed into the holes on the insulation board and the outer wall of the concrete wall by a tightening gun. The threaded column is threadedly connected to the concrete wall, and the side wall of the rivet plate abuts against the side wall of the insulation wall panel. Under the limit of the rivet plate, the insulation wall panel is fixed to the side wall of the concrete wall, thereby achieving the fixation of the insulation wall panel.

[0004] In order to improve the stability of the connection between the insulation wall connector and the concrete wall, the above-mentioned insulation wall connector usually has a plastic sleeve threaded on the outer wall of the insulation wall connector. In the process of fixing the insulation board, the plastic sleeve is pre-inserted into the hole opened on the side wall of the concrete wall, and then the threaded column is screwed into the plastic sleeve. The threaded column and the plastic sleeve of this insulation wall connector are separately arranged. Before fixing the insulation board, the plastic sleeve is first twisted to separate the plastic sleeve from the threaded column, and then the plastic sleeve is inserted into the hole on the side wall of the concrete wall, and finally the threaded column is screwed onto the plastic sleeve. This process of fixing the insulation board is relatively cumbersome and there is room for improvement. Utility Model Content

[0005] In order to simplify the steps of fixing the insulation board and make the fixing of the insulation board more convenient, the present application provides an insulation wall connector.

[0006] The present application provides a thermal insulation wall connector, which adopts the following technical solution:

[0007] A thermal insulation wall connector comprises a rod body and a baffle fixed on the outer wall of the rod body, the side wall of the baffle plate abuts against the side of the thermal insulation plate facing away from the concrete wall, a plurality of resistance grooves are opened on the outer wall of the rod body, the resistance grooves are distributed on both sides of the baffle plate, a limiting block is fixed on the outer wall of the rod body, and a plurality of blocking spikes are fixed on the outer wall of the limiting block.

[0008] By adopting the above technical solution, a hole for fixing the insulation wall connector is pre-opened on the side wall of the insulation board, and the insulation wall connector is plugged and fixed on the insulation board, so that the baffle abuts against the side wall of the insulation board. During the construction of the building, the inner leaf wall is cast and fixed on the outer wall of the building in advance, and before the inner leaf wall solidifies, the end of the insulation wall connector is embedded in the inner leaf wall, so that the side of the insulation board away from the baffle abuts against the side wall of the inner leaf wall, and finally concrete is poured on the outer wall of the insulation board to form an outer leaf wall on the outer wall of the insulation board. After the concrete solidifies, the insulation board is fixed to the outer wall of the inner leaf wall under the restriction of the resistance groove, and the fixing of the insulation board and the insulation wall connector is more stable under the restriction of the blocking thorn, thereby making the fixing of the insulation board more stable. Since the insulation wall connector is set as a single body and there is no need to open a hole in the outer wall of the wall in advance, the steps of fixing the insulation board are reduced, thereby improving the efficiency of fixing the insulation board.

[0009] Optionally, the blocking barb includes a first barb and a second barb, the side walls of the first barb are provided with a guide surface, the second barb is arranged at an inclination, and the inclination direction of the second barb is toward the baffle.

[0010] By adopting the above technical solution, the positioning member is divided into a first positioning part and a second positioning part according to the shape of the rod body, and the setting of a plurality of first barbs and second barbs enables the insulation wall connector to be connected to the insulation board in blocks, thereby making the connection between the insulation board and the insulation wall connector more stable. When the insulation wall connector is plugged and fixed to the side wall of the insulation board, the guide surface plays a guiding role in the plugging of the insulation wall connector, and the setting of the second barb set in an inclined manner reduces the abutment between the insulation wall connector and the inner wall of the insulation board during the plugging of the insulation wall connector, thereby facilitating the plugging and fixing between the insulation wall connector and the insulation board; after the insulation wall connector is plugged and fixed on the insulation board, the first barb and the second barb abut against the inner wall of the hole on the side wall of the insulation board in different directions, respectively, to better limit the relative slip between the insulation board and the insulation wall connector, thereby making the insulation wall connector fix the insulation board more stable.

[0011] Optionally, the opening directions of several resistance grooves are different.

[0012] By adopting the above technical solution, after the insulation wall connector is inserted into the unsolidified concrete, the resistance groove is filled with concrete. After the concrete solidifies, the resistance groove limits the insulation wall connector. The opening directions of the resistance groove are different, so that the inner leaf wall and the outer leaf wall act on the insulation wall connector in different directions, thereby making the insulation wall connector fix the insulation wall more stably.

[0013] Optionally, the rod body includes a first connecting rod and a second connecting rod, the first connecting rod rotates on the side wall of the baffle, a support block is fixed on the outer wall of the second connecting rod, the support block is located close to the limit block, the support block is conical in shape, the outer wall of the support block can abut against the inner wall of the limit block, the support block drives the support block to move toward the inner cavity of the limit block, and a driving rod is fixed to the end of the first connecting rod, and the driving rod is threadedly connected to the support block.

[0014] By adopting the above technical solution, when fixing the insulation wall connector to the insulation board, the second connecting rod is inserted into the hole on the side wall of the insulation board, and the first connecting rod is rotated. The first connecting rod drives the driving rod to rotate, and the driving rod drives the second connecting rod to move. The second connecting rod drives the support block to move. Under the guidance of the side wall of the support block, the side wall of the support block abuts against the side wall of the supporting plate, and the support block drives the supporting plate to move outward, so that the first barb and the second barb are inserted into the inner wall of the hole on the side wall of the insulation board, thereby making the connection between the insulation wall connector and the insulation board more stable.

[0015] Optionally, one end of the first connecting rod away from the second connecting rod is set to be pointed, and one end of the second connecting rod away from the first connecting rod is set to be pointed.

[0016] By adopting the above technical solution, the contact area between the thermal insulation wall connector and the concrete is reduced, thereby facilitating the insertion of the thermal insulation wall connector into the concrete.

[0017] By adopting the above technical solution, the possibility of the insulation wall connecting piece rotating after the insulation board is fixed to the outer wall of the wall is reduced, so that the fixation of the insulation board is more stable.

[0018] In summary, the present application includes at least one of the following beneficial technical effects:

[0019] 1. Fix the insulation wall connector on the insulation board in advance, insert the end of the insulation wall connector into the wall before the wall solidifies, fix the insulation wall connector on the outer wall of the wall after the wall solidifies, and fix the insulation board on the outer wall of the wall under the limit of the insulation wall connector. This kind of insulation wall connector fixes the insulation board without the need for the staff to drill holes on the side wall of the insulation board in advance, making the fixation of the insulation board more convenient.

[0020] 2. After the insulation wall connector is integrally formed with the wall, the inner wall of the resistance groove is filled with concrete. Under the limitation of the resistance groove, the connection between the insulation wall connector and the wall is more stable, reducing the possibility of the insulation board detaching from the outer wall of the wall.

[0021] 3. The first barb and the second barb have different shapes and different distribution positions, which improves the stability of the connection between the insulation wall connector and the insulation board while reducing the resistance during the assembly process of the insulation wall connector and the insulation board, providing convenience for the staff.

[0022] 4. After the insulation wall connector is fixed on the insulation board, the end of the limiting piece abuts against the side wall of the insulation board, and the fixing of the insulation wall connector and the insulation board is more stable under the limitation of the limiting piece.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-4 This application is described in further detail.

[0029] An embodiment of the present application discloses a thermal insulation wall connector.

[0030] Embodiment 1

[0031] Reference Figure 1A heat preservation wall connector includes a rod body 1 and a baffle 2. In the present application, the rod body 1 includes a first connecting rod 11 and a second connecting rod 12. The first connecting rod 11 is welded and fixed on the side wall of the baffle 2. The second connecting rod 12 is arranged on the side of the baffle 2 away from the first connecting rod 11. The first connecting rod 11 and the second connecting rod 12 are respectively located on both sides of the baffle 2. The second connecting rod 12 is inserted into a hole reserved on the side wall of the heat preservation board, the side wall of the baffle 2 abuts against the side wall of the heat preservation board, and the second connecting rod 12 is fixedly connected to the heat preservation board, so that the heat preservation board connecting rod is fixed on the heat preservation board.

[0032] Reference Figure 1 The first connecting rod 11 is provided with a resistance groove 3 on its outer wall, and the second connecting rod 12 is also provided with a resistance groove 3 on its outer wall. The resistance grooves 3 on the outer walls of the first connecting rod 11 and the second connecting rod 12 are oriented in opposite directions. When the inner leaf wall is not solidified, the end of the second connecting rod 12 is inserted into the inner leaf wall. After the inner leaf wall is solidified, the second connecting rod 12 is fixed to the inner leaf wall. Then, the outer leaf wall is fixedly coated on the side of the insulation board away from the inner leaf wall. The first connecting rod 11 is located in the outer leaf wall. After the outer leaf wall is solidified, the first connecting rod 11 is fixedly connected to the outer leaf wall. The insulation board is fixed to the wall under the fixation of the insulation wall connector.

[0033] Reference Figure 1 After the insulation wall connector is fixed on the wall, the resistance groove 3 is filled with solidified concrete. The opening of the resistance groove 3 increases the contact area between the first connecting rod 11 and the outer leaf wall, and increases the contact area between the second connecting rod 12 and the outer leaf wall. Under the restriction of the resistance groove 3, the connection between the insulation wall connector and the wall is more stable, thereby making the fixation of the insulation board more stable.

[0034] Reference Figure 1 and Figure 2 A limit block 4 is welded and fixed on the side wall of the baffle 2, and the limit block 4 is located on the side of the baffle 2 away from the first connecting rod 11. The second connecting rod 12 is welded and fixed to the end of the limit block 4 away from the baffle 2. A blocking thorn 5 is fixed on the outer wall of the limit block 4. After the insulation board is fixed to the wall, the limit block 4 is located inside the inner leaf wall. The setting of the blocking thorn 5 plays a positioning role, so that the fixation of the limit block 4 and the inner leaf wall is more stable, thereby making the fixation of the insulation board and the wall more stable.

[0035] Reference Figure 1 and Figure 2The limit block 4 includes a first positioning portion 41 and a second positioning portion 42 integrally fixed on the side wall of the first positioning portion 41. The first positioning portion 41 and the second positioning portion 42 are both welded and fixed on the side wall of the baffle 2. The blocking thorn 5 includes a first barb 51 welded and fixed on the outer wall of the first positioning portion 41 and a second barb 52 welded and fixed on the outer wall of the second positioning portion 42. In the present application, the first barb 51 preferably uses a rectangular structure. A guide surface 6 is provided on the side wall of the first barb 51. The opening of the guide surface 6 makes the first barb 51 have a triangular prism shape. The opening of the guide surface 6 guides the plug-in fixation of the limit block 4 and the insulation board, thereby making the fixation of the limit block 4 and the insulation board more convenient.

[0036] Reference Figure 1 and Figure 2 The second barb 52 is arranged at an angle, and the inclination direction of the second barb 52 is toward the outer wall of the baffle 2. In the process of inserting the limit block 4 into the hole on the side wall of the insulation board, the inclination direction of the second barb 52 is opposite to the moving direction of the limit block 4, reducing the possibility of the second barb 52 blocking the sliding of the limit block 4, thereby making the fixing method of the limit block 4 and the insulation board more stable.

[0037] Reference Figure 1 The first connecting rod 11 and the second connecting rod 12 are both flat structures, which increase the contact area between the insulation wall connector and the wall while avoiding the possibility of the insulation wall connector rotating and loosening, thereby making the insulation board more stably fixed.

[0038] In the first embodiment of the present application, the implementation principle of an insulation wall connector is as follows: a groove matching the second connecting rod 12 is pre-opened on the side wall of the insulation board, and the second connecting rod 12 is inserted into the hole on the side wall of the insulation board so that the side wall of the baffle 2 abuts against the side wall of the insulation board. Before the inner leaf wall is solidified, the end of the second connecting rod 12 away from the baffle 2 is inserted into the inner leaf wall. After the inner leaf wall is solidified, the second connecting rod 12 is fixed to the inner leaf wall, the insulation board is fixed to the outer wall of the inner leaf wall, and concrete is coated on the outer wall of the insulation board to form an outer leaf wall. After the outer leaf wall is solidified, the first connecting rod 11 is fixedly connected to the outer leaf wall, thereby completing the installation of the building insulation board. The insulation wall connector is a single integral part, and there is no need to open a hole on the outer wall of the wall during the process of fixing the insulation board, thereby simplifying the installation process of the insulation board.

The driving rod 8 is threadedly connected to the support block 7, and the cross-sectional area of ​​the support block 7 gradually decreases along the direction from the second connecting rod 12 to the baffle 2, and the support block 7 is driven to move during the rotation of the first connecting rod 11.

[0041] Reference Figure 3 The limit block 4 is hollow, and a plurality of through slots 43 are provided on the side wall of the limit block 4. The through slots 43 are connected to the inner cavity of the limit block 4, and the through slots 43 are connected to the edge of the limit block 4 near one end of the second connecting rod 12.

The first barb 51 is welded and fixed on the outer wall of the first positioning portion 41, and the second barb 52 is welded and fixed on the outer wall of the second positioning portion 42. The support block 7 is located at the ends of the first positioning portion 41 and the second positioning portion 42. The first connecting rod 11 is rotated, and the first connecting rod 11 drives the support block 7 to move between the first positioning portion 41 and the second positioning portion 42. Under the support of the support block 7, the first positioning portion 41 and the second positioning portion 42 are opened, and the first barb 51 and the second barb 52 move toward the inner side wall of the hole on the insulation board, so that the connection between the limit block 4 and the insulation board is more stable.

[0042] In the second embodiment of the present application, the implementation principle of an insulation wall connector is as follows: the second connecting rod 12 is inserted into the hole on the side wall of the insulation board, and then the first connecting rod 11 is rotated. The first connecting rod 11 drives the driving rod 8 to rotate, and the driving rod 8 drives the support block 7 to move toward between the first positioning portion 41 and the second positioning portion 42. Under the drive of the support block 7, the first positioning portion 41 and the second positioning portion 42 are stretched open, and the first barb 51 and the second barb 52 are moved toward the inner wall of the insulation board. The first barb 51 and the second barb 52 are inserted into the inner wall of the insulation board.
