Description

Technical Field

[0001] This invention relates to the field of curtain wall testing technology, and more specifically, to a device for testing the firmness of building curtain wall panels. Background Technology

[0002] Building curtain walls are a widely used exterior facade structure in modern architecture. They not only provide an aesthetically pleasing appearance but also serve the vital function of protecting the building's interior from external environmental influences. Curtain walls are typically made of materials such as glass, stone, and metal, and are fixed to the building structure through a complex support system. Glass curtain walls, with their transparency and modern aesthetic, are widely used in high-rise buildings and commercial centers, while stone curtain walls are favored for their durability and natural texture. The diversity and complexity of these materials make the installation and maintenance of curtain walls a significant challenge in the architectural field.

[0003] The robustness of a building's curtain wall directly affects its safety and lifespan. In daily use, curtain walls are exposed to various natural factors such as wind pressure, earthquakes, and temperature changes. These factors can cause deformation, loosening, or even detachment of the curtain wall materials, leading to serious safety accidents. Therefore, regularly inspecting the robustness of curtain wall panels is a crucial step in ensuring building safety. Through scientific and accurate testing methods, potential safety hazards can be identified promptly, allowing for appropriate maintenance measures to extend the curtain wall's lifespan and protect the safety of people and property.

[0004] Currently, the stability of building curtain wall panels is typically tested using suction cups. This method applies negative pressure to the panel surface and measures the deformation under suction to assess its stability. However, this method has significant limitations. Suction cups are only effective on smooth glass panels; they are ineffective on rough or irregular surfaces such as stone or metal, making testing impossible. Summary of the Invention

[0005] The purpose of this invention is to provide a device for testing the firmness of building curtain wall panels, which is applicable to the firmness testing of curtain wall panels with rough or irregular surfaces.

[0006] The embodiments of the present invention are achieved through the following technical solution: a building curtain wall panel firmness testing device, including a testing frame, a clamping assembly on the testing frame for clamping the edge of the panel, a testing rod rotatably mounted on the testing frame, a reaction rod at the bottom end of the testing rod, the reaction rod being perpendicular to the testing rod and inserted into the gap between the panel and the wall. In the testing state, the reaction rod bends and deforms to abut against the wall and the panel. A distance measuring instrument is mounted on the testing frame for detecting the distance the panel moves relative to the wall during the testing process, and the panel's firmness is determined by comparing the moving distance with a preset length.

[0007] Furthermore, the reaction rod includes a first metal strip, a second metal strip, and a heating wire. The first metal strip and the second metal strip are riveted together and have different coefficients of thermal expansion. The heating wire is disposed between the first metal strip and the second metal strip for heating the first metal strip and the second metal strip.

[0008] Furthermore, the surface of the reaction rod is provided with a heat insulation layer.

[0009] Furthermore, the testing frame is provided with a windproof plate, one side of which is rotatably connected to the testing frame, and the other side of which abuts against the surface of the panel.

[0010] Furthermore, a cooling water pipe is provided inside the reaction rod, and cooling water is installed in the cooling water pipe. A circulating injector is provided on the detection frame, and the circulating injector is connected to the cooling water pipe.

[0011] Furthermore, a cooling fan is provided on the testing frame, and the cooling fan faces the exposed cooling water pipe.

[0012] Furthermore, the clamping assembly includes a rotating rod rotatably mounted on the detection frame, a hook rod vertically mounted at the bottom end of the rotating rod, the hook rod extending into the gap between the panels, the rotating rod rotating in the opposite direction to the detection rod, and a pressing rod slidably mounted on the body of the rotating rod, the pressing rod and the hook rod clamping the two sides of the panel respectively.

[0013] Furthermore, the hook rod is provided with an adsorption hole, which is inclined.

[0014] Furthermore, a torsion spring is provided on the detection frame, and the detection rod is fixedly connected to the bottom end of the torsion spring. The torsion spring drives the detection rod to rotate until the reaction rod rotates into the gap between the panel and the wall.

[0015] Furthermore, the detection frame has a limiting hole groove, which is open on the side facing the reaction rod. A limiting protrusion is provided on the rod body of the detection rod, and the limiting protrusion is slidably disposed in the limiting hole groove.

[0016] The technical solutions of the embodiments of the present invention have at least the following advantages and beneficial effects: 1. In this invention, the reaction rod is passed through the gap between the panel and the wall. The reaction rod is heated by the heating wire, causing it to bend and deform and come into contact with the inside of the panel, pushing the panel to move away from the wall. When the distance the panel moves exceeds the specified distance, the panel is considered to have poor stability. This invention does not use suction cups or other devices and is more suitable for testing curtain wall panels with uneven surfaces. 2. The present invention increases the bending speed of the reaction rod by heating the first and second metal strips with an electric heating wire; 3. This invention uses a circulating syringe to drive the flow of cooling water in the cooling water pipe. The cooling water carries away the heat from the reaction rod, which helps to increase the cooling speed of the reaction rod and accelerates the return of the reaction rod to its original state.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention. Example

[0022] The following description, in conjunction with specific embodiments, provides further details. Figures 1-9 As shown, this invention is a device for testing the firmness of building curtain wall panels, referring to... Figure 1 The device includes a testing frame 10, which serves as the support structure for the entire apparatus. The testing frame 10 is elongated and is installed in the gap between the panels 40. A clamping assembly is provided on the testing frame 10 to clamp onto the edge of the panel 40 adjacent to the panel to be tested, thus fixing the position of the testing frame 10.

[0023] Reference Figure 2The clamping assembly is used to clamp the edge of the panel 40 to ensure the stability of the inspection frame 10 during the inspection process. The clamping assembly includes a rotating rod 20 rotatably mounted on the inspection frame 10, with the rotating rod 20 perpendicular to the surface of the panel 40. A pressing rod 21 is slidably mounted on the body of the rotating rod 20, and a sliding ring 22 is fixedly connected to the end of the pressing rod 21. The sliding ring 22 is sleeved on the body of the rotating rod 20, and a locking bolt 23 is rotatably mounted on the inner wall of the sliding ring 22. The end of the locking bolt 23 passes through the side wall of the sliding ring 22 and abuts against the body of the rotating rod 20 to restrict the sliding ring 22 from sliding freely on the rotating rod 20. A hook rod 24 is vertically mounted at the bottom end of the rotating rod 20, and the hook rod 24 is parallel to the pressing rod 21. During the clamping process, the hook rod 24 is first inserted into the gap between the panels 40, and the rotating rod 20 is controlled to rotate, causing the hook rod 24 to rotate towards the gap between a panel 40 and the wall 50 until it hooks onto the inner side of the panel 40. The position of the pressing rod 21 relative to the rotating rod 20 is changed, so that the pressing rod 21 and the hook rod 24 are clamped on both sides of the panel 40 respectively, thus fixing the detection frame 10 relative to the panel 40. An elastic pad 25 is provided on the pressing rod 21 to increase the stability and reliability of the clamping. Multiple adsorption holes 241 are opened on the side of the hook rod 24 facing the pressing rod 21. The adsorption holes 241 are inclined so that the hook rod 24 can be more stably hooked onto the surface of the panel 40. Furthermore, the hook rod 24 is made of a composite material in which fiber-reinforced materials (such as carbon fiber and glass fiber) are added to rubber or silicone. This can improve the tensile strength and tear resistance of the material without affecting its flexibility and adhesion. In addition, the hook rod 24, made of rubber or silicone, has a microporous structure inside, which allows air in the adsorption hole 241 to be discharged through the micropores.

[0024] Reference Figure 2 , Figure 3 and Figure 4A detection rod 30 is rotatably mounted on the detection frame 10, parallel to and offset from the rotating rod 20. A reaction rod 31 is located at the bottom of the detection rod 30. At room temperature, the reaction rod 31 is perpendicular to the detection rod 30 and is used to insert into the gap between the panels 40. The reaction rod 31 includes a first metal strip 301, a second metal strip 302, a heating wire 303, and a cooling water pipe 304. The first metal strip 301 and the second metal strip 302 are riveted together and have different coefficients of thermal expansion. The heating wire 303 is positioned between the first metal strip 301 and the second metal strip 302 to heat them. The detection rod 30 rotates in the opposite direction to the rotating rod 20. When the detection rod 30 is rotated, causing the reaction rod 31 to move into the gap between another panel 40 and the wall 50, the first metal strip 301 is located between the second metal strip 302 and the panel 40. After the heating wire 303 heats the reaction rod 31, the reaction rod 31 bends due to the difference in thermal expansion coefficients, pushing the panel 40 to move relatively away from the wall 50. A heat insulation layer 32 is provided on the surface of the reaction rod 31 to prevent excessive heat loss and protect the panel 40 from heat damage. In this embodiment, multiple detection rods 30 are arranged along the length of the detection frame 10. These multiple detection rods 30 are inserted into the gaps between the panels 40 to detect the firmness of the panel 40 at different positions. Control handles 26 for manually controlling the rotation angle are installed on both the rotating rod 20 and the detection rod 30 to facilitate manual control when they become stuck or restricted.

[0025] It should be emphasized that the testing frame 10 is also equipped with a temperature detection module and a controller. The output end of the temperature detection module is connected to the reaction rod 31 to detect the real-time temperature of the reaction rod 31 and output a temperature detection signal to upload the real-time temperature of the reaction rod 31 to the controller. The controller controls the current of the heating wire 303 and the heating time according to the real-time temperature of the reaction rod 31, so as to monitor and control the temperature of the metal component in real time during the heating process.

[0026] The temperature detection module, which can be equipped with thermocouples, thermistors, or infrared temperature sensors, is placed in or around the heating area of ​​the metal component to collect actual temperature data of the metal surface. The controller is electrically connected to the temperature detection module, receives the collected temperature signal, compares it with the set target temperature range, and automatically adjusts the current or heating time to ensure a controlled and stable heating process. This prevents excessively high temperatures from causing uneven metal plasticity or excessive elongation errors, thereby improving the accuracy and consistency of metal deformation.

[0027] Furthermore, a laser displacement sensor or other high-precision displacement detection device can be added to the deformation path of the reaction rod 31 to directly monitor the displacement change during the metal deformation process. The displacement sensor records the elongation or contraction distance of the free end of the metal through non-contact measurement, forming real-time feedback data on the deformation length. The controller compares this length change value with a preset target value and automatically adjusts the output current of the power supply and the heating duration accordingly, achieving precise control of the metal deformation and ensuring that the deformation distances between multiple metal components are equal and synchronized. This solution is particularly suitable for applications requiring high consistency and high precision thermal deformation, further improving the stability and intelligence level of the overall system performance.

[0028] Reference Figure 2 A rangefinder 33 is installed on the bottom surface of the testing frame 10 to detect the distance the panel 40 moves during the testing process. The rangefinder 33 is a laser rangefinder, which has the advantages of high measurement accuracy and fast response speed. By measuring the moving distance of the panel 40, the stability of the panel 40 can be quantitatively assessed.

[0029] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 A cooling water pipe 304 is installed inside the reaction rod 31, and the cooling water pipe 304 is filled with cooling water to ensure that the reaction rod 31 can quickly return to its original state after testing. A circulating injector 11 is installed on the testing frame 10. The circulating injector 11 is connected to the water inlet of the cooling water pipe 304 to circulate the cooling water and accelerate the cooling process of the reaction rod 31. An exhaust valve 305 is also installed on the cooling water pipe 304. In this embodiment, a partition is provided inside the cooling water pipe 304, which extends along the length of the cooling water pipe 304 and divides the cooling water pipe 304 into two halves. The lower temperature cooling water flows towards the reaction rod 31 through one half of the cooling water pipe 304 under the action of the circulating injector 11. At the same time, the hot water inside the reaction rod 31 flows towards the exhaust valve 305 through the other half of the cooling water pipe 304. A cooling fan 12 is also provided on the testing frame 10, and the air outlet of the cooling fan 12 faces the exposed cooling water pipe 304 to further improve the cooling effect. In this embodiment, a battery is provided on the detection frame 10, which is used to provide power to the cooling fan 12.

[0030] Reference Figure 3 and Figure 6The detection frame 10 has a limiting hole groove 14, which is designed to be open on the side facing the panel 40. The detection rod 30 passes through the limiting hole groove 14, and a limiting protrusion 34 is provided on the rod body of the detection rod 30. The limiting protrusion 34 is slidably disposed in the limiting hole groove 14 to limit the rotation of the detection rod 30 in the initial state, making it easier to place the reaction rod 31 into the gap between the panels 40.

[0031] Reference Figure 3 and Figure 6 The detection frame 10 is also equipped with a torsion spring 15, and the detection rod 30 is fixedly connected to the bottom end of the torsion spring 15. When the limiting protrusion 34 disengages from the limiting hole groove 14, the torsion spring 15 drives the detection rod 30 to rotate until the reaction rod 31 automatically rotates into the gap between the panel 40 and the wall 50.

[0032] Reference Figure 1 and Figure 7 A windproof plate 16 is rotatably mounted on the outside of the testing frame 10. Rotary seats are mounted on both sides of the testing frame 10. One side of the windproof plate 16 has a rotating hole through which a rotating shaft passes. The other side of the windproof plate 16 abuts against the surface of the panel 40. A limiting gear 17 is mounted at the end of the windproof plate 16, and a limiting plate 18 is elastically mounted on the side of the testing frame 10. The surface of the limiting plate 18 has locking teeth that mesh with the limiting gear to limit the rotation angle of the windproof plate 16. The windproof plates 16 on both sides of the testing frame 10 cover the gap between the panels 40, preventing wind from affecting the changes in the reaction rod 31.

[0033] The working process of this embodiment is as follows: First, clean the debris, such as adhesive, from the gaps between the panels 40 to expose the gaps. Install the inspection frame 10 in the gaps between the panels 40, and clamp the edges of the other panels 40 using the clamping assembly to ensure the stability of the inspection frame 10. First, insert the hook rod 24 into the gap between the panels 40, and control the rotation rod 20 to rotate so that the hook rod 24 abuts against the inner side of the panel 40. Adjust the position of the pressing rod 21 so that the pressing rod 21 and the hook rod 24 are respectively clamped on both sides of the panel 40, thus completing the fixation of the inspection frame 10.

[0034] Reference Figure 8 Adjust the orientation of the reaction rod 31 in the detection rod 30 so that the reaction rod 31 is first inserted into the gap between the panels 40 to be tested. Push the detection rod 30 towards the panel 40 to be tested, so that the limiting protrusion 34 disengages from the limiting hole groove 14. Under the elastic force of the torsion spring 15, the detection rod 30 and the reaction rod 31 are driven to rotate until the reaction rod 31 moves into the gap between the panel 40 to be tested and the wall 50. At this time, the first metal strip 301 of the reaction rod 31 is located between the second metal strip 302 and the panel 40.

[0035] Reference Figure 9 The heating wire 303 is activated to heat the reaction rod 31. Due to the difference in thermal expansion coefficients between the first metal strip 301 and the second metal strip 302, the reaction rod 31 bends upon heating, pushing the panel 40 away from the wall 50. The temperature detection module and controller detect and control the degree of deformation of the reaction rod 31. The laser rangefinder on the detection rod 30 measures the moving distance of the panel 40 in real time and transmits the data to the control device.

[0036] Throughout the testing process, the windproof plate 16 remains in contact with the surface of the panel 40 to prevent external wind from interfering with the reaction rod 31 and to ensure the accuracy of the test results.

[0037] After the test is completed, the cooling system is activated. The circulating injector 11 circulates the cooling water, and the cooling fan 12 blows air onto the cooling water pipe 304 to accelerate the cooling process of the reaction rod 31. After the reaction rod 31 cools down, it returns to its original position. The detection rod 30 is rotated in the opposite direction, and the detection rod 30 is pulled to remove the reaction rod 31 from the gap between the panels 40. The adhesive used to fill the gap between the panels 40 is then reapplied.

[0038] Based on the movement distance of panel 40 measured by rangefinder 33, and combined with the dimensions and material parameters of panel 40, the robustness index of panel 40 is calculated. By comparing with standard values ​​or historical data, the robustness of panel 40 is evaluated to determine whether it meets the requirements.

[0039] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
