Description

Technical Field

[0001] This application relates to the field of exterior wall panel performance testing devices, and in particular to a thermal insulation performance testing device for a unitized composite exterior wall. Background Technology

[0002] Exterior wall cladding panels are a type of building exterior wall insulation material. They are made of polyester paint, aluminum alloy steel plates, polyurethane insulation layers, and fiberglass cloth, and are fixed to the building exterior wall by adhesives or other methods. They provide decoration, thermal insulation, energy saving, and sound insulation functions. Before using exterior wall cladding panels, their insulation performance needs to be tested to determine whether their insulation capacity meets the building's requirements.

[0003] Existing testing methods for exterior wall decorative panels include fixing the exterior wall panel, heating one side of the exterior wall panel, and measuring the temperature rise rate on the side of the exterior wall panel away from the heat source. Users need to fix the exterior wall panel vertically, install a heating resistance wire on one side of the exterior wall panel to heat the exterior wall panel, and install a temperature sensor on the side of the exterior wall panel away from the heating resistance wire to measure the temperature rise rate of the exterior wall panel, thereby judging the thermal insulation performance of the exterior wall panel.

[0004] The aforementioned technical solutions have the following drawbacks: when inspecting multiple exterior wall panels, multiple users are required to collaborate during the inspection, resulting in low inspection efficiency. Utility Model Content

[0005] To improve the efficiency of testing multiple exterior wall panels, this application provides a device for testing the thermal insulation performance of unitized composite exterior walls.

[0006] The thermal insulation performance testing device for unitized composite exterior walls provided in this application adopts the following technical solution: A thermal insulation performance testing device for a unitized composite exterior wall includes a frame, multiple fixing mechanisms, two telescopic mechanisms, and a heating mechanism. The frame is a right-angled frame structure. The two telescopic mechanisms are respectively installed at both ends of the frame. The multiple fixing mechanisms are installed on the frame. The fixing mechanisms are used to clamp the exterior wall panels, and the telescopic mechanisms are used to lock onto the edges of the exterior wall panels. The heating mechanism is set on the frame and is used to heat the exterior wall panels.

[0007] By adopting the above technical solution, a fixing mechanism is set on the frame to allow the exterior wall panel to be fixed onto the frame, ensuring the exterior wall panel is vertically positioned. A telescopic mechanism is set on the frame to lock onto the two corners of the exterior wall panel, thus maintaining the stability of the exterior wall panel. A heating mechanism is set on one side of the frame to abut against one side of the exterior wall panel. Users can detect temperature changes in the exterior wall panel by setting temperature sensors on both sides of the exterior wall panel, thereby achieving the detection effect.

[0008] Optionally, the frame is provided with a card slot.

[0009] By adopting the above technical solution, the exterior wall panels can be secured in the slots created on the frame, thereby reducing the chance of the exterior wall panels sliding horizontally on the frame and improving the installation stability of the exterior wall panels.

[0010] Optionally, the fixing mechanism includes a mounting base, a screw, and a clamp. The mounting base is fixed to the frame, the screw passes through the mounting base and is threadedly connected to the mounting base, and the clamp is installed at the end of the screw.

[0011] By adopting the above technical solution, and by setting a screw on the mounting base, the user can make the clamp move horizontally in the direction of approaching or moving away from the frame by turning the screw, so that the clamp can abut against the outer wall panel in the slot, and the outer wall panel can be vertically fixed on the frame.

[0012] Optionally, the clamp is provided with a guide rod, which is rotatably connected to the end of the screw. The guide rod passes through the mounting base and is slidably connected to the mounting base. One end of the guide rod is fixed to the clamp, and the length direction of the guide rod is parallel to the screw.

[0013] By adopting the above technical solution, and by setting a guide rod on the clamp, the guide rod can achieve a limiting effect. When the screw rotates, the clamp can be kept relatively stationary, thereby reducing the chance of the clamp rotating and the outer wall panel falling off the frame.

[0014] Optionally, the telescopic mechanism includes a connecting seat, a slide rod one, a retaining frame, a guide rod two, and a pre-tensioning spring. The connecting seat is fixed on the frame, the slide rod one passes through the connecting seat and is slidably connected to the connecting seat, the retaining frame is fixed to the end of the slide rod one, the guide rod two passes through the connecting seat and is parallel to the slide rod one, and the pre-tensioning spring is sleeved on the slide rod one, with one end of the pre-tensioning spring fixed on the slide rod one and the other end fixed on the connecting seat.

[0015] By adopting the above technical solution, by setting a sliding rod on the connecting seat, the card frame can slide on the connecting seat via the sliding rod. By setting a pre-tightening spring on the sliding rod, the card frame can always be locked at the edge of the outer wall panel. By pulling the card frame, the user can lock the card frame onto outer wall panels of different sizes, thereby the frame can fix outer wall panels of different sizes.

[0016] Optionally, the heating mechanism includes a mounting bracket, a second sliding rod, a contact spring, and a heating element. The mounting bracket is fixed on the frame, the second sliding rod passes through and is slidably connected to the mounting bracket, the heating element is fixed to the end of the second sliding rod, and the contact spring is sleeved on the second sliding rod, with one end of the contact spring abutting against the mounting bracket and the other end abutting against the sliding rod.

[0017] By adopting the above technical solution, by setting a sliding rod two on the mounting frame and setting a heating element at the end of the sliding rod two, the user can move the heating element through the sliding rod two, so that the heating element can heat the exterior wall panel fixed on the frame. By setting an abutment spring on the sliding rod two, the abutment spring abuts the heating element against the exterior wall panel, thereby keeping the heating element in contact with the exterior wall panel when heating the exterior wall panel.

[0018] Optionally, the slide rod 2 has a threaded portion, and the mounting bracket has a through hole. The slide rod 2 is slidably connected in the through hole, and an internal thread is provided in the through hole near the frame end. The threaded portion is used for threaded connection with the mounting bracket.

[0019] By adopting the above technical solution, and by opening a threaded part on the slide rod two, when the user pulls the slide rod two, the heating element can be moved away from the outer wall panel. At this time, the threaded part can abut against the internal threaded hole on the mounting bracket. By screwing the slide rod two, the user can make the slide rod two threadedly connected to the mounting bracket, thereby keeping the heating element away from the outer wall panel. At this time, the user can replace the outer wall panel to be tested.

[0020] Optionally, heat-insulating sleeves are provided at both ends of the slide rod, and the heat-insulating sleeves are fitted over the heating element.

[0021] By adopting the above technical solution, and by setting a heat insulation sleeve on the slide rod 2, so that the heat insulation sleeve is fitted outside the heating element and the end of the heating element extends out from the heat insulation sleeve, the probability of users accidentally triggering the heating element can be reduced.

[0022] In summary, the beneficial technical effects of this application are as follows: 1. By setting a fixing mechanism on the frame, the exterior wall panel can be fixed to the frame, making the exterior wall panel vertical. By setting a telescopic mechanism on the frame, the telescopic mechanism is respectively fixed at two corners of the exterior wall panel, thus keeping the exterior wall panel in a stable position. By setting a heating mechanism on one side of the frame, the heating mechanism can abut against one side surface of the exterior wall panel. Users can detect the temperature change of the exterior wall panel by setting temperature sensors on both sides of the exterior wall panel, thereby achieving the detection effect. 2. By setting a screw on the mounting base, the user can turn the screw to make the clip move horizontally in the direction of approaching or moving away from the frame, so that the clip can abut against the outer wall panel in the slot, and the outer wall panel can be vertically fixed on the frame. 3. By setting a sliding rod on the connecting seat, the card frame can slide on the connecting seat via the sliding rod. By setting a pre-tightening spring on the sliding rod, the card frame can always be locked at the edge of the outer wall panel. By pulling the card frame, the user can lock the card frame onto outer wall panels of different sizes, thereby the frame can fix outer wall panels of different sizes. Attached Figure Description

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] This application discloses a device for testing the thermal insulation performance of a unitized composite exterior wall, referring to... Figure 1 and Figure 2 The system includes a frame 1, multiple fixing mechanisms 2, multiple telescopic mechanisms 3, and a heating mechanism 4. The frame 1 is a right-angled frame. The fixing mechanisms 2 are installed on the frame 1 and are used to hold the exterior wall panel to be tested. The telescopic mechanisms 3 are installed at both ends of the frame 1 and are used to hold the edges of the exterior wall panel. The heating mechanism 4 is installed on the frame 1 and is used to press against the exterior wall panel and heat it. The heating mechanism 4 heats one side of the exterior wall panel. Users can detect the temperature of both sides of the exterior wall panel to test its thermal insulation performance.

[0030] Reference Figure 1The frame 1 is vertically arranged, and a bracket 12 is fixed to the lower side of the frame 1 to support the frame 1. A slot 11 is opened on one side of the frame 1, and the outer wall panel is placed in the slot 11. The fixing mechanism 2 includes a mounting base 21, a screw 22, a clamp 23, and a guide rod 24. The mounting base 21 is fixed to the outside of the frame 1. The screw 22 passes through the mounting base 21 and is threadedly connected to the mounting base 21. The clamp 23 is rotatably connected to the end of the screw 22 and is located on the side of the frame 1 where the slot 11 is opened. The guide rod 24 passes through the mounting base 21 and is slidably connected to the mounting base 21. The length direction of the guide rod 24 is parallel to the length direction of the screw 22, and one end of the guide rod 24 is fixed to the clamp 23. The user screws the screw 22 so that the screw 22 can move relative to the mounting base 21, thereby adjusting the distance between the clamp 23 and the frame 1, so that the clamp 23 can clamp the outer wall panel on the frame 1. The guide rod 24 plays a limiting role, which can keep the clamp 23 in contact with the outer wall panel at all times, reducing the chance of the clamp 23 rotating on the screw 22 and causing the outer wall panel to fall off the frame 1.

[0031] Reference Figure 1 The telescopic mechanism 3 includes a connecting seat 31, a sliding rod 32, a retaining frame 33, a guide rod 34, and a pre-tension spring 35. The connecting seat 31 is fixed to the end of the frame 1. The sliding rod 32 passes through and is slidably connected to the connecting seat 31. The retaining frame 33 is fixed to the sliding rod 32 and is used to retain the edge of the exterior wall panel. The guide rod 34 passes through the connecting seat 31 and is slidably connected to the connecting seat 31. The end of the guide rod 34 is fixed to the retaining frame 33. The guide rod 34 and the sliding rod 32 are arranged parallel to each other. The pre-tension spring 35 is sleeved on the sliding rod 32. One end of the pre-tension spring 35 is fixed to the sliding rod 32, and the other end is fixed to the connecting seat 31. The pre-tension spring 35 is used to pull the sliding rod 32, so that the retaining frame 33 is always retained on the exterior wall panel.

[0032] Reference Figure 1 The heating mechanism 4 is fixed to the frame 1. The heating mechanism 4 includes a mounting bracket 41, a sliding rod 42, a contact spring 43, and a heating element 44. The mounting bracket 41 is fixed to the frame 1, and the sliding rod 42 passes through the mounting bracket 41 and is slidably connected to it. When the exterior wall panel is fixed to the frame 1, the sliding rod 42 is perpendicular to the exterior wall panel. The heating element 44 is fixed to the end of the sliding rod 42 near the frame 1. The heating element 44 can be a heating resistance wire, which converts electrical energy into heat energy to heat the exterior wall panel. The contact spring 43 is sleeved on the sliding rod 42, with one end fixed to the sliding rod 42 and the other end fixed to the mounting bracket 41. The contact spring 43 allows the heating element 44 to contact the exterior wall panel in its natural state.

[0033] Reference Figure 3The sliding rod 42 has a threaded part 421, and the mounting bracket 41 has a through hole. The sliding rod 42 is slidably connected in the through hole. The through hole has an internal thread on the side near the frame 1. The user can pull the sliding rod 42 to move the heating element 44 away from the outer wall panel. The threaded part 421 on the sliding rod 42 can contact the internal thread in the through hole. At this time, the user can screw the sliding rod 42 to make the sliding rod 42 threadedly connected to the mounting bracket 41, thereby keeping the heating element 44 away from the outer wall panel, which makes it convenient for the user to measure the temperature and replace the outer wall panel.

[0034] Reference Figure 4 The end of the slide bar 42 is fitted with a heat insulation sleeve 45. The heat insulation sleeve 45 is made of rigid heat insulation material. The heat insulation sleeve 45 is fitted over the heating element 44 and plays a protective role, which can reduce the chance of users accidentally triggering the heating element 44 and getting burned.

[0035] The implementation principle of this application embodiment is as follows: by setting a fixing mechanism 2 on the frame 1, the outer wall panel can be fixed on the frame 1; by setting a telescopic mechanism 3 on the frame 1, the frame 1 can be locked onto one side of the square outer wall panel; by setting two telescopic mechanisms 3 respectively locked onto the edge of the outer wall panel, the square outer wall panel is fixed; by setting a heating mechanism 4 on the frame 1, the heating mechanism 4 can abut against one side of the outer wall panel and heat the outer wall panel; users can use non-contact temperature sensors to measure the temperature on both sides of the outer wall panel respectively, thereby achieving the effect of detecting the thermal insulation performance of the outer wall panel.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
