Description

Technical Field

[0001] This application belongs to the field of building curtain wall performance testing technology, and more specifically, it relates to a building curtain wall impact resistance testing device. Background Technology

[0002] Currently, the exterior of a building's main structure is typically encased in a curtain wall to enhance its aesthetic appeal. However, during the construction of curtain walls, quality issues such as incomplete sealing of the sealant or improper construction of the supporting structure can easily arise. Furthermore, after construction, curtain walls are constantly exposed to wind and rain. Under the influence of wind pressure, rainwater, gaps, flying debris during strong winds, and birds, curtain walls are prone to further corrosion of the supporting structure and loosening of the panels. Therefore, it is necessary to conduct impact resistance tests on curtain walls to ensure that their load-bearing capacity meets relevant requirements.

[0003] According to the standard "Classification and Testing Methods for Impact Resistance of Building Curtain Walls" (GB / T 38264-2019), impact resistance testing includes laboratory testing and outdoor field testing. However, most existing building curtain wall impact resistance testing devices are generally bulky and difficult to lift, and require close-range operation by staff, which poses safety hazards during the operation process. As a result, they are not suitable for outdoor field testing environments, making it difficult to conduct impact resistance testing on building curtain walls located at high altitudes outdoors. Summary of the Invention

[0004] The purpose of this application is to provide a building curtain wall impact resistance testing device, which aims to solve the problem that most current building curtain wall impact resistance testing devices have complex structures that are difficult to lift, require close-range operation by personnel which poses safety hazards during operation, and are therefore unsuitable for outdoor on-site testing environments, making it difficult to test the impact resistance of building curtain walls located at high altitudes outdoors.

[0005] To achieve the above objectives, the technical solution adopted in this application is to provide a building curtain wall impact resistance testing device, characterized in that it includes a fixed bracket, a first winch, a second winch, a traction wire, an electromagnetic suction block, a traction steel rope, and an impact component. The first winch and the second winch are both mounted on the fixed bracket. The traction wire and the traction steel rope are respectively wound around the first winch and the second winch, and the traction wire and the traction steel rope are respectively connected to the electromagnetic suction block and the impact component. The electromagnetic suction block is used to electromagnetically attract the impact component.

[0006] In one embodiment, the impact assembly includes a support shaft, a soft weight, a magnetic object, and two sets of counterweights. A traction steel cable is connected to one end of the support shaft. The soft weight and the two sets of counterweights are coaxially fixed to the support shaft. The soft weight is located in the middle of the support shaft along its axial direction. The two sets of counterweights are arranged symmetrically at opposite ends of the soft weight along its axial direction. The magnetic object is disposed on the support shaft or formed on any set of counterweights.

[0007] In one embodiment, the impact assembly further includes two sets of elastic stops, which are arranged axially along the support shaft at opposite ends of the soft heavy object. Each elastic stop includes a support plate, a connecting hook, two movable frames, and two arc-shaped stops. The support shaft passes through and fixes the support plate. The two movable frames are arranged radially and adjacently on the side of the support plate facing away from the soft heavy object. Each side of the two movable frames is elastically connected to the support plate by a torsion spring. The two arc-shaped stops are respectively located on the sides of the two movable frames that are far apart from each other. The connecting hook connects the sides of the two movable frames that are far apart from each other to bring them closer together. The two movable frames drive the two arc-shaped stops to be radially limited to the inner edge of the soft heavy object. When the soft heavy object impacts the building curtain wall and causes the connecting hook to fall off, the two movable frames immediately rebound and reset, and each drive the two arc-shaped stops to extend radially along the support shaft to the outer edge of the soft heavy object. Both arc-shaped stops are elastic bodies and covered with energy-absorbing sponges.

[0008] In one embodiment, when each movable frame drives each arc-shaped stop block to extend radially outward from the edge of the soft, heavy object along the support shaft, the two pairs of arc-shaped stops in the two sets of elastic stops are 90° rotationally symmetrical about the axis of the support shaft, and the center angle of each arc-shaped stop block is greater than or equal to 60° and less than or equal to 90°.

[0009] In one embodiment, two sets of elastic stops are respectively arranged at the ends of the two sets of counterweights facing away from the soft weight.

[0010] In one embodiment, the connecting hook includes a fixed connecting end and a hook connecting end, which are respectively connected to two movable frames on opposite sides.

[0011] In one embodiment, the soft heavy object includes a plurality of rubber tires that are stacked sequentially along the axial direction of the support shaft and coaxially fixed to the support shaft.

[0012] In one embodiment, the first winch and the second winch are respectively disposed at opposite ends of the fixed bracket, and the end of the fixed bracket adjacent to the second winch is covered with anti-collision foam.

[0013] In one embodiment, a reference target is suspended at one end of the fixed bracket adjacent to the second winch.

[0014] In one embodiment, a set of movable wheels is provided at one end of the fixed bracket adjacent to the first winch.

[0015] The beneficial effect of the building curtain wall impact resistance testing device provided in this application is that, compared with the prior art, the aforementioned building curtain wall impact resistance testing device includes a fixed bracket, a first winch, a second winch, a traction wire, an electromagnetic chuck, a traction steel rope, and an impact component. The first and second winches are both mounted on the fixed bracket, and the traction wire and traction steel rope are respectively wound around the first and second winches. The traction wire and traction steel rope are respectively connected to the electromagnetic chuck and the impact component. The electromagnetic chuck is used to electromagnetically attract the impact component. Thus, when conducting impact resistance testing on building curtain walls located high outdoors, it is only necessary to fix the fixed bracket to the bottom of the crane basket, and use the electromagnetic chuck to electromagnetically attract the impact component. The second winch can be remotely controlled to adjust the traction steel cable to a suitable length and then lock it. The first winch can be remotely controlled to lift the electromagnetic suction block and impact component (while keeping the traction steel cable taut) to a suitable height and then lock it. When the crane basket raises the fixed support to the appropriate position, the electromagnetic suction block can be remotely de-energized, causing the impact component to fall and impact the outdoor building curtain wall test area, thus completing the impact resistance test of the building curtain wall located at a high altitude outdoors. The above-mentioned building curtain wall impact resistance test device has a simple structure, is easy to fix and lift, and allows personnel to perform remote control operations from a safe area, avoiding safety hazards caused by flying debris when the impact component impacts the outdoor building curtain wall.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0032] Please refer to the following: Figure 1 and Figure 2The following describes an embodiment of the building curtain wall impact resistance testing device 10 provided in this application. The building curtain wall impact resistance testing device 10 is applicable to testing the impact resistance of outdoor or indoor building curtain walls against soft heavy objects based on the standard "Classification and Testing Methods for Impact Resistance of Building Curtain Walls" (GB / T 38264-2019). Specifically, it includes a fixed bracket 100, a first winch 200, a second winch 300, a traction wire 400, an electromagnetic suction block 500, a traction steel rope 600, and an impact component 700. The first winch 200 and the second winch 300 are both mounted on the fixed bracket 100. The traction wire 400 and the traction steel rope 600 are respectively connected to the electromagnetic suction block 500 and the impact component 700. It should be noted that the first winch 200 and the second winch 300 are both remotely controlled electric winches. The traction wire 400 is electrically connected to the electromagnetic suction block 500, so that the electromagnetic suction block 500 can electromagnetically attract the impact component 700 after being powered on.

[0033] The beneficial effect of the building curtain wall impact resistance testing device 10 provided in this application is that, compared with the prior art, the building curtain wall impact resistance testing device 10 includes a fixed bracket 100, a first winch 200, a second winch 300, a traction wire 400, an electromagnetic suction block 500, a traction steel rope 600, and an impact component 700. The first winch 200 and the second winch 300 are both mounted on the fixed bracket 100. The traction wire 400 and the traction steel rope 600 are respectively wound around the first winch 200 and the second winch 300, and are respectively connected to the electromagnetic suction block 500 and the impact component 700. The electromagnetic suction block 500 is used to electromagnetically attract the impact component 700. Thus, when testing the impact resistance of a building curtain wall located high in the outdoor environment, it is only necessary to fix the fixed bracket 100 to the bottom of the crane basket and use electromagnetic... The electromagnetic suction block 500 and the impact component 700 can be remotely controlled to adjust the traction steel cable 600 to a suitable length and then lock the second winch 300. The first winch 200 can be remotely controlled to pull up the electromagnetic suction block 500 and the impact component 700 together (while keeping the traction steel cable 600 taut) to a suitable height and then lock the first winch 200. When the crane basket raises the fixed bracket 100 to the appropriate position, the electromagnetic suction block 500 can be remotely de-energized to allow the impact component 700 to detach and fall to impact the outdoor building curtain wall testing area, thus completing the impact resistance test of the building curtain wall located at a high altitude outdoors. The above-mentioned building curtain wall impact resistance testing device 10 has a simple structure, is easy to fix and lift, and allows personnel to perform remote control operations from a safe area, avoiding safety hazards caused by flying fragments when the impact component 700 impacts the outdoor building curtain wall.

[0034] by Figure 1 or Figure 2Taking a medium-angle view as an example, in this embodiment, the first winch 200 and the second winch 300 are respectively disposed at opposite ends of the fixed bracket 100. A set of movable wheels 120 is provided at one end of the fixed bracket 100 adjacent to the first winch 200. Thus, after the fixed bracket 100 is erected, the building curtain wall impact resistance testing device 10 can be quickly moved and fixed via the set of movable wheels 120. The end of the fixed bracket 100 adjacent to the second winch 300 is covered with impact-resistant foam 110. One end of the 0 is also suspended by a reference object 800. When the impact component 700 impacts the building curtain wall detection area, it is at the same vertical height as the reference object 800. In this way, after the fixed bracket 100 is lifted by the crane basket and the reference object 800 is at the same vertical height as the building curtain wall detection area, it can be determined that the impact component 700 can impact the building curtain wall detection area. The end of the fixed bracket 100 covered with anti-collision foam 110 is fixed to the building curtain wall to prevent the fixed bracket 100 from moving accidentally and affecting the detection results.

[0035] Specifically, in this embodiment, the first winch 200 and the second winch 300 are respectively disposed at opposite ends of the bottom surface of the fixed bracket 100, thereby facilitating the fixing of the top surface of the fixed bracket 100 to the bottom of the crane basket.

[0036] Please refer to the following: Figure 3 and Figure 4 In this embodiment, the impact assembly 700 includes a support shaft 710, a soft weight 720, a magnetic object 740, and two sets of counterweights 730. The traction steel rope 600 is connected to one end of the support shaft 710. The soft weight 720 and the two sets of counterweights 730 are all ring-shaped and fixed around the support shaft 710. The soft weight 720 is located in the middle of the support shaft 710 along the axial direction. The two sets of counterweights 730 are arranged symmetrically at opposite ends of the soft weight 720 along the axial direction of the support shaft 710. The outer diameter of the two sets of counterweights 730 is smaller than the outer diameter of the soft weight 720. The outer side wall of the soft weight 720 parallel to the axial direction of the support shaft 710 is used to contact the impact detection area of ​​the building curtain wall. The magnetic object 740 is formed on any set of counterweights 730.

[0037] Furthermore, in some other embodiments, the end of the traction steel rope 600 away from the second winch 300 has multiple connecting rope ends (not shown in the figure), and the multiple connecting rope ends are respectively connected to one end of the fixed support shaft 710 and multiple areas on a group of adjacent counterweights 730, effectively preventing the impact component 700 from accidentally loosening and falling off the traction steel rope 600 during the impact with the building curtain wall detection area; in some other embodiments, the magnetic object 740 can also be coaxially and fixed to the support shaft 710.

[0038] Furthermore, in this embodiment, the impact assembly 700 further includes two sets of elastic stops 750, which are arranged axially along the support shaft 710 at opposite ends of the soft weight 720. Specifically, the two sets of elastic stops 750 are respectively arranged at one end of the two sets of counterweights 730 facing away from the soft weight 720. Each set of elastic stops 750 includes a support plate 751, a connecting hook 752, two movable frames 753, and two arc-shaped stops 754, supporting... The shaft 710 is perpendicularly inserted through the center of the support plate 751 and fixedly connected to the support plate 751. Two movable frames 753 are arranged radially adjacent to each other along the support shaft 710 on the side of the support plate 751 facing away from the soft heavy object 720. Each adjacent side of the two movable frames 753 is elastically connected to the support plate 751 by a torsion spring (not shown in the figure). Two arc-shaped stops 754 are respectively set on the opposite sides of the two movable frames 753. Please refer to the attached figures. Figure 3 , Figure 5 and Figure 6 The connecting hooks 752 connect the two movable frames 753 to each other on opposite sides, bringing them closer together. The two movable frames 753 then drive the two arc-shaped stops 754 to be radially limited along the support shaft 710 to the inner edge of the soft, heavy object 720. Please refer to the attached document. Figure 4 , Figure 7 and Figure 8 When the soft heavy object 720 impacts the building curtain wall, causing the connecting hook 752 to detach, the two movable frames 753 immediately spring back to their original positions and drive the two arc-shaped blocks 754 to extend radially along the support shaft 710 to the outer edge of the soft heavy object 720. Each arc-shaped block 754 is used to prevent the soft heavy object 720 from impacting the building curtain wall detection area once, thus preventing the soft heavy object 720 from impacting the building curtain wall detection area again and affecting the detection results. Both arc-shaped blocks 754 are elastic bodies and covered with energy-absorbing sponge (not shown in the figure). Through the elastic structure of the arc-shaped blocks 754 and the energy-absorbing sponge, the impact force of the arc-shaped blocks 754 with the building curtain wall can be greatly reduced.

[0039] Furthermore, in this embodiment, when the aforementioned movable frames 753 drive the arc-shaped stops 754 to extend radially outward from the edge of the soft, heavy object 720 along the support shaft 710, the two pairs of arc-shaped stops 754 in the two sets of elastic stops 750 are 90° rotationally symmetrical about the axis of the support shaft 710, and the central angle of each arc-shaped stop 754 is greater than or equal to 60° and less than or equal to 90°; please refer to the following: Figure 7 and Figure 8 In one specific embodiment, the center angle of each arc stop 754 is 90°.

[0040] Please see Figure 9In this embodiment, the connecting hook 752 has a fixed connecting end 7521 and a hook connecting end 7522. The fixed connecting end 7521 and the hook connecting end 7522 are respectively connected to the two movable frames 753 on opposite sides. When the soft heavy object 720 hits the building curtain wall detection area, the hook connecting end 7522 will detach from the corresponding movable frame 753, while the fixed connecting end 7521 will remain fixedly connected to the other movable frame 753, thus facilitating reuse.

[0041] Please see Figure 10 In some other embodiments, the connecting hook 752 and each movable frame 753 are made of steel wire. The fixed connecting end 7521 of the connecting hook 752 is fixed around one side of a movable frame 753, and the hook connecting end 7522 of the connecting hook 752 is hung on one side of the corresponding other movable frame 753. Each arc-shaped stop 754 is made of foam.

[0042] Furthermore, in this embodiment, the aforementioned soft heavy object 720 includes a plurality of rubber tires that are stacked sequentially along the axial direction of the support shaft 710 and coaxially fixed to the support shaft 710.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
