Description

Technical Field

[0001] This utility model relates to the field of building insulation, and in particular to an energy-saving insulation wall panel for building exterior walls. Background Technology

[0002] The use of thermal insulation wall panels is of great significance for energy conservation and emission reduction. By reducing the transfer of heat between indoors and outdoors, thermal insulation wall panels can effectively reduce the energy consumption of buildings. In winter, they can prevent indoor heat from escaping to the outside, reducing the use of heating energy; in summer, they can reduce the conduction of high outdoor temperatures to the interior, reducing air conditioning energy consumption, thereby significantly reducing building energy consumption and emissions of greenhouse gases such as carbon dioxide, which has a positive significance for environmental protection and energy conservation and emission reduction.

[0003] According to the description in the patent application published on the Internet as an energy-saving thermal insulation wall panel for building exterior walls (authorization announcement number: CN215563525U), it "includes a building exterior wall and an insulation board, the insulation board is movably connected to the building exterior wall, the building exterior wall has a hollow cavity inside, the hollow cavity has a sliding groove fixedly installed on both sides, the insulation board has a slider fixedly installed on both sides, the slider is slidably connected to the sliding groove, the building exterior wall surface has a plurality of first limiting holes fixedly penetrating through it, the insulation board surface has a plurality of second limiting holes fixedly penetrating through it, and the positions of the first limiting holes and the second limiting holes are corresponding."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In the process of using this utility model, because the building's exterior wall has a hollow cavity inside, and sliding grooves are fixedly installed on both sides of the hollow cavity, and sliders are fixedly installed on both sides of the insulation board, with the sliders slidably connected to the sliding grooves, this type of insulation wall panel is not easy to remove from the hollow cavity. When dealing with large walls, lifting equipment may be required. The assembled wall is not easy to disassemble, posing a risk of damaging the wall. Therefore, it is necessary to improve the energy-saving insulation wall panel for building exterior walls to solve the above problems. Utility Model Content

[0006] To overcome the difficulty of removing existing insulated wall panels from the hollow cavity, lifting equipment may be needed when dealing with large walls, and the assembled walls are not easy to disassemble, which may damage the walls.

[0007] The technical solution of this utility model is: an energy-saving thermal insulation wall panel for building exterior walls, including an exterior wall, a connecting device provided on the exterior wall, the connecting device being able to connect and fix the thermal insulation panel, a collection box provided below the connecting device, the connecting device including a square tube, the square tube including an oil inlet and an oil outlet.

[0008] Preferably, the insulation board can be detachably connected to the exterior wall via the connecting device. To ensure that the connecting device can be easily disassembled at any time, lubricating oil or rust-preventive oil needs to be injected into the connecting device. The connecting device is lubricated and rust-prevented by adding oil to the oil inlet. To prevent oil from falling to the ground from the oil outlet and polluting the environment, a collection box is provided below the connecting device. The oil collected in the collection box can be recycled and reused, achieving the purpose of environmental protection.

[0009] Preferably, the square tube is fixed to the outer wall by rivets. The square tube is provided with a bearing position, in which a bearing can be installed. The bearing includes an inner hole into which a rotating column can be inserted. The rotating column and the inner hole are interference-fitted. The rotating column includes a base plate. When the rotating column is inserted into the inner hole, the base plate is located on the side of the bearing closer to the outer wall. The square tube of the connecting device is fixed to the outer wall. The bearing installed in the bearing position allows the rotating column to rotate. By rotating the rotating column, the purpose of fixing or removing the insulation board can be achieved.

[0010] Preferably, the insulation board is provided with mounting holes corresponding to the rotating column. A handle is connected to the side of the rotating column away from the base plate. The mounting hole is provided with a clearance for the handle in the axial direction. After the rotating column passes through the mounting hole, the rotating column is rotated so that the handle falls naturally under the action of gravity. Then the handle is tightened to prevent the handle from being opened at will. Here, the tightening method can be a common tightening method such as shaft pin engagement or stop bolt engagement.

[0011] Preferably, the upward-facing end of the square tube is the oil inlet, and the downward-facing end is the oil outlet. Oil is injected through the upper oil inlet, and the oil is discharged from the lower oil outlet under the influence of gravity, thus lubricating the bearings in the bearing positions. The bearing positions are not limited to the two shown in the figure; the specific number can be determined according to the size of the outer wall.

[0012] Preferably, the outer ring of the bearing is provided with an oil passage channel one and an oil passage channel two. The oil passage channel one faces the oil inlet, and the oil passage channel two faces the oil outlet. The bearing used here adopts a design with a dust cover plate. The dust cover plate is used to slow down the rapid flow of oil from the bearing. Since the outer ring and the bearing position are interference-fitted, the outer ring is fixed relative to the outer wall. The oil passage channel one faces the oil inlet, and the oil passage channel two faces the oil outlet, which facilitates the oil to enter the different bearing positions in a square tube in sequence. The oil passage channel one and the oil passage channel two should not be too large, only large enough to facilitate the rolling of the balls in the bearing.

[0013] Preferably, the collection box includes a collection chamber located below the oil outlet. By placing the collection chamber below the oil outlet, oil dripping onto other parts of the collection box is prevented, reducing environmental pollution. Preferably, the insulation board is made of polystyrene resin, which is lightweight, high-strength, has excellent thermal insulation properties, excellent processing performance, is resistant to chemical corrosion and oil corrosion, is environmentally friendly and recyclable, and has low economic cost.

[0014] The beneficial effects of this utility model are:

[0015] 1. The insulation board can be detachably connected to the exterior wall through the connecting device. In order to ensure that the connecting device can be easily disassembled at any time, lubricating oil or rust-preventive oil needs to be injected into the connecting device. The connecting device is lubricated and rust-prevented by adding oil to the oil inlet. In order to prevent oil from falling to the ground from the oil outlet and polluting the environment, a collection box is provided below the connecting device. The oil collected in the collection box can be recycled and reused, achieving the purpose of environmental protection. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6 , Figure 6The dashed arrow in the middle indicates the direction of oil flow. This utility model provides an embodiment: an energy-saving thermal insulation wall panel for building exterior walls, including an exterior wall 1. A connecting device 2 is provided on the exterior wall 1, which can connect and fix an insulation board 3. A collection box 4 is provided below the connecting device 2. The connecting device 2 includes a square tube 21, which includes an oil inlet 212 and an oil outlet 213. The insulation board 3 can be detachably connected to the exterior wall 1 through the connecting device 2. In order to ensure that the connecting device 2 can be easily disassembled at any time, lubricating oil or rust-preventive oil needs to be injected into the connecting device 2. The connecting device 2 is lubricated and rust-prevented by adding oil to the oil inlet 212. In order to prevent oil from falling to the ground from the oil outlet 213 and polluting the environment, a collection box 4 is provided below the connecting device 2. The oil collected by the collection box 4 can be recycled and reused, achieving the purpose of environmental protection.

[0025] Please see Figures 2-6In this embodiment, the square tube 21 is fixed to the outer wall 1 by rivets. The square tube 21 has a bearing seat 211, within which a bearing 2111 can be installed. The bearing 2111 includes an inner hole 2112 into which a rotating column 22 can be inserted. The rotating column 22 and the inner hole 2112 are interference-fitted. The rotating column 22 includes a base plate 221. When the rotating column 22 is inserted into the inner hole 2112, the base plate 221 is located on the side of the bearing 2111 closest to the outer wall 1. The square tube 21 of the connecting device 2 is fixed to the outer wall 1. The bearing 2111 installed in the bearing seat 211 allows the rotating column 22 to rotate, thereby achieving the purpose of fixing or disassembling the insulation board 3. The insulation board 3 has a mounting hole 31 corresponding to the rotating column 22. A handle 222 is connected to the side of the rotating column 22 away from the base plate 221. The mounting hole 31 has an axial clearance 32 for the handle 222. After the rotating column 22 passes through the mounting hole 31, rotate the rotating column 22 to allow the handle 222 to fall naturally under gravity. Then, tighten the handle 222 to prevent it from being opened arbitrarily. The tightening method can be a common method such as a pin engagement or a locking bolt engagement. The upward-facing part of the square tube 21 is the oil inlet 212, and the downward-facing part is the oil outlet 213. Oil is injected through the upper oil inlet 212, and the oil is discharged from the lower oil outlet 213 under gravity, thus lubricating the bearing 2111 inside the bearing seat 211. The bearing seat 211 is not limited to the two shown in the figure; the specific number can be determined according to the size of the outer wall 1. The outer ring 2113 of the bearing 2111 has an oil passage 1 2114 and an oil passage 2115. The oil passage 1 2114 faces the oil inlet 212, and the oil passage 2115 faces the oil outlet 213. The bearing 2111 used here is designed with a dust cover. The dust cover is used to slow down the rapid flow of oil from the inside of the bearing 2111. Since the outer ring 2113 is interference-fitted with the bearing position 211, the outer ring 2113 is fixed relative to the outer wall 1. The first oil passage 2114 faces the oil inlet 212, and the second oil passage 2115 faces the oil outlet 213, so that the oil can enter the different bearing positions 211 in a square tube 21 in sequence. The first oil passage 2114 and the second oil passage 2115 should not be too large, only large enough to facilitate the rolling of the balls or rollers inside the bearing 2111.

[0026] Please see Figure 1In this embodiment, the collection box 4 includes a collection chamber 41, which is located below the oil outlet 213. By placing the collection chamber 41 below the oil outlet 213, oil dripping onto other parts of the collection box 4 is prevented, reducing environmental pollution. The insulation board 3 is made of polystyrene resin. Polystyrene resin is lightweight and high-strength, has excellent thermal insulation properties, excellent processing performance, is resistant to chemical corrosion and oil corrosion, is environmentally friendly and recyclable, and has low economic cost.

[0027] During the work, the construction workers first need to install the connecting device 2 onto the outer wall 1. Specifically, the square tube 21 is riveted to the outer wall 1 using a rivet gun. Then, the rotating column 22 is passed through the inner hole 2112 of the bearing 2111, and the bearing 2111 is pushed to fit the base plate 221. At this point, the construction workers place the base plate 221 and the bearing 2111 together in the bearing position 211, and use a rubber mallet to fully hammer the bearing 2111 into the bearing position 211. It is worth noting that the oil passage 2114 of the bearing 2111 needs to face upwards. At this time, the cover plate of the bearing 2111 needs to be completed. The installation is not shown in the diagram. Finally, the construction worker installs the handle 222 on the end of the rotating column 22 away from the bearing position 211, thus completing the installation of the connecting device 2. When heat preservation or cold preservation is required, the construction worker aligns the mounting hole 31 of the insulation board 3 with the rotating column 22 and aligns the angle between the handle 222 and the clearance position 32. The insulation board 3 is then pushed into the outer wall 1 along the axial direction of the rotating column 22. The construction worker then adjusts the rotating column 22 until the handle 222 is in a state of hanging down under gravity. After the operation is completed, the construction worker needs to tighten the handle 222 to prevent the insulation board 3 from falling off. When maintaining the connecting device 2, the construction worker injects oil through the oil inlet 212. The oil flows along the square tube 21 into the bearing position 211. In the bearing position 211, the oil enters the first oil passage 2114 of the bearing 2111, and then flows out from the second oil passage 2115. When the oil has flowed through all the bearing positions 211 in the square tube 21, the maintenance of the connecting device 2 is completed. The oil that flows out will be discharged from the oil outlet 213 and collected in the collection chamber 41 of the collection box 4. The construction worker pours the oil in the collection chamber 41 into the oil bucket for future use. Through the above steps, the insulation board 3 can be detachably connected to the exterior wall 1 via the connecting device 2. In order to ensure that the connecting device 2 can be easily disassembled at any time, lubricating oil or rust-preventive oil needs to be injected into the connecting device 2. The connecting device 2 is lubricated and rust-prevented by adding oil to the oil inlet 212. In order to prevent oil from falling to the ground from the oil outlet 213 and polluting the environment, a collection box 4 is provided below the connecting device 2. The oil collected by the collection box 4 can be recycled and reused to solve the problem that the existing insulation wall panels are not easy to remove from the hollow cavity, may require lifting equipment when facing large walls, and are not easy to disassemble after assembly, which may damage the wall.
