Description

Technical Field

[0001] This utility model belongs to the field of glass curtain wall testing technology, and specifically relates to a device for testing the wind pressure resistance of glass curtain walls. Background Technology

[0002] Building curtain walls are a common structure in modern buildings. After installation, they are subject to environmental factors over time, which can lead to a decline in their performance indicators. For example, accidents such as glass falling from the curtain wall often occur. In addition to the inherent problems of the curtain wall components (such as the glass expanding and cracking due to high temperatures), wind force is also a factor in the falling of curtain wall components. Therefore, wind pressure resistance testing is required before building curtain walls are used.

[0003] Chinese patent CN221993210U discloses a glass curtain wall wind pressure resistance testing device, including a static pressure chamber. An insertion port for the curtain wall to enter the static pressure chamber is provided on one outer wall. The upper and lower walls inside the static pressure chamber are symmetrically provided with sliding grooves for the curtain wall to slide within. A locking groove for the curtain wall to engage is provided on the inner wall opposite the insertion port. The curtain wall is fixedly installed inside the static pressure chamber under the constraint of the sliding groove and locking groove. A sealing plate that can completely close the insertion port is rotatably provided on the side facing outwards. The sliding groove, locking groove, and insertion port divide the interior of the static pressure chamber into a testing area and a detection area. An air pump for testing the wind pressure resistance of the curtain wall is fixedly installed in the testing area inside the static pressure chamber, with the air pump's outlet facing the curtain wall. A displacement sensor is slidably installed in the detection area inside the static pressure chamber, with the sensor's detection end facing the curtain wall.

[0004] To test the ultimate wind pressure resistance of glass curtain walls, the glass curtain walls will inevitably shatter during the test, requiring the collection and unified treatment of glass fragments. In the aforementioned document, after the curtain wall shatters, the fragments are collected through a perforated grille into a collection tray within a collection box. However, when testing glass curtain walls of different sizes, the center position of the glass curtain wall will change, causing the airflow from the air pump to be misaligned with the center of the glass curtain wall, easily leading to errors in the test results.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a wind pressure resistance testing device for glass curtain walls to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a wind pressure resistance testing device for glass curtain walls, comprising a testing box, an adjustment component inside the testing box, a clamping component on the outer surface of the adjustment component, a testing component on the back of the testing box, and a collection component at the bottom of the testing box. The adjustment component is used to change the position of the clamping component, the clamping component is used to fix the glass curtain wall, the testing component is used to test the wind pressure resistance of the glass curtain wall, and the collection component is used to collect debris from the glass curtain wall.

[0009] Furthermore, the adjustment assembly includes a connecting seat, which is fixedly connected to the inside of the detection box. Bolts are threaded onto the outer surface of the connecting seat, and a connecting plate is fixedly installed on the connecting seat by the bolts. An electric push rod is fixedly connected to the outer surface of the connecting plate.

[0010] Furthermore, the clamping assembly includes a clamping seat, which is fixedly connected to the movable end of the electric push rod. A screw is threadedly connected to the outer surface of the clamping seat. A knob is fixedly connected to one end of the screw, and a clamping plate is rotatably connected to the other end of the screw. The clamping plate is slidably connected to the clamping seat.

[0011] Furthermore, the detection component includes a fan, an air guide pipe is fixedly connected to the outer surface of the fan, the air guide pipe is fixedly connected to the detection box, the air guide pipe and the detection box are interconnected, and a detection gauge is fixedly connected to the outer surface of the air guide pipe.

[0012] Furthermore, the collection assembly includes a fixing base, which is fixedly connected to the bottom of the detection box. The fixing base has a cavity inside, and a collection box is slidably connected inside the cavity. The cavity and the detection box communicate with each other.

[0013] Furthermore, a door is rotatably connected to the outer surface of the testing box.

[0014] Furthermore, a handle is fixedly connected to the outer surface of the collection box.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model connects the adjusting component and the clamping component. The clamping component is located at the movable end of the adjusting component. When the adjusting component extends or retracts, it can drive the clamping component to move, thereby changing the distance between multiple sets of clamping components. This allows the clamping component to clamp and fix glass curtain walls of different sizes, making it more flexible to use. Furthermore, the center of the multiple sets of clamping components is in the same position as the axis of the air outlet of the detection component, ensuring that the center of glass curtain walls of different sizes is always in the same axis as the air outlet of the detection component, thus avoiding deviations in the detection results.

[0017] 2. This utility model connects the clamping seat and the clamping plate. The clamping plate is slidably connected inside the clamping seat. When the knob and the screw are rotated, the screw moves on the clamping seat and pushes the clamping plate to slide inside the clamping seat. The distance between the clamping seat and the clamping plate can be adjusted, which is convenient for fixing glass curtain walls of different thicknesses and is more flexible in use.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements 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 the utility model.

[0030] Please see Figures 1-6 As shown, this utility model is a wind pressure resistance testing device for glass curtain walls, including a testing box 1. An adjustment component 2 is provided inside the testing box 1, and a clamping component 3 is provided on the outer surface of the adjustment component 2. A testing component 4 is provided on the back of the testing box 1, and a collection component 5 is provided at the bottom of the testing box 1. The adjustment component 2 is used to change the position of the clamping component 3, the clamping component 3 is used to fix the glass curtain wall, the testing component 4 is used to test the wind pressure resistance of the glass curtain wall, and the collection component 5 is used to collect the debris of the glass curtain wall.

[0031] Place the glass curtain wall into the testing box 1, activate the adjustment component 2 inside the testing box 1 to move the clamping component 3, and after the glass curtain wall is placed in the clamping component 3, the clamping component 3 fixes the glass curtain wall. Then activate the testing component 4 on the back of the testing box 1. The testing component 4 blows air onto the glass curtain wall and records the wind pressure data when the glass curtain wall breaks. The broken glass curtain wall fragments fall into the collection component 5 for unified processing by staff.

[0032] This invention connects the adjusting component 2 and the clamping component 3. The clamping component 3 is located at the movable end of the adjusting component 2. When the adjusting component 2 extends or retracts, it can drive the clamping component 3 to move, thereby changing the distance between the multiple clamping components 3. This allows the clamping component 3 to clamp and fix glass curtain walls of different sizes, making it more flexible to use. Furthermore, the center of the multiple clamping components 3 is in the same position as the axis of the air outlet of the detection component 4, ensuring that the center of glass curtain walls of different sizes is always in the same axis as the air outlet of the detection component 4, thus avoiding deviations in the detection results.

[0033] In one embodiment, the adjustment component 2 includes a connecting seat 201, which is fixedly connected to the inside of the detection box 1. The outer surface of the connecting seat 201 is threaded with a bolt 202. A connecting plate 203 is fixedly installed on the connecting seat 201 by the bolt 202. An electric push rod 204 is fixedly connected to the outer surface of the connecting plate 203.

[0034] There are four sets of adjustment components 2. The connecting seats 201 in the four sets of adjustment components 2 are located at the four corners of the detection box 1. The electric push rod 204 is fixed to the connecting seat 201 by the connecting plate 203 and the bolt 202. After the electric push rod 204 is started, the movable end of the electric push rod 204 can push the clamping component 3 to move.

[0035] In one embodiment, the clamping assembly 3 includes a clamping seat 301, which is fixedly connected to the movable end of the electric push rod 204. A screw 302 is threadedly connected to the outer surface of the clamping seat 301. A knob 303 is fixedly connected to one end of the screw 302, and a clamping plate 304 is rotatably connected to the other end of the screw 302. The clamping plate 304 is slidably connected to the clamping seat 301.

[0036] The glass curtain wall is placed between the clamping seat 301 and the clamping plate 304. Rotating the knob 303 drives the screw 302 to rotate. Through the threaded connection between the screw 302 and the clamping seat 301, the screw 302 and the clamping plate 304 slide within the clamping seat 301. At this time, the clamping seat 301 and the clamping plate 304 can clamp the glass curtain wall. The distance between the clamping seat 301 and the clamping plate 304 can be adjusted, so that glass curtain walls of different thicknesses can be clamped and fixed, making it more flexible in use.

[0037] In one embodiment, the detection component 4 includes a fan 401, an air duct 402 is fixedly connected to the outer surface of the fan 401, the air duct 402 is fixedly connected to the detection box 1, the air duct 402 and the detection box 1 communicate with each other, and a detection gauge 403 is fixedly connected to the outer surface of the air duct 402.

[0038] When the fan 401 is started, it draws outside air into the air duct 402. The gauge 403 on the air duct 402 is used to detect the wind speed and wind pressure inside the air duct 402. The air duct 402 blows the air onto the glass curtain wall inside the test box 1. The data of the gauge 403 when the glass curtain wall breaks is the wind pressure resistance of the glass curtain wall.

[0039] In one embodiment, the collection component 5 includes a fixing base 501, which is fixedly connected to the bottom of the detection box 1. A cavity 502 is provided inside the fixing base 501, and a collection box 503 is slidably connected inside the cavity 502. The cavity 502 communicates with the detection box 1.

[0040] The broken glass curtain wall fragments pass through the detection box 1 and fall into the cavity 502 inside the fixing seat 501 at the bottom of the detection box 1. The collection box 503 in the cavity 502 collects the glass curtain wall fragments. After pulling the collection box 503 to slide it out of the cavity 502 on the fixing seat 501, the glass curtain wall fragments in the collection box 503 can be cleaned.

[0041] In one embodiment, for the above-mentioned detection box 1, a box door 6 is rotatably connected to the outer surface of the detection box 1.

[0042] When conducting wind pressure tests on the glass curtain wall inside the testing chamber 1, the chamber door 6 is closed. The chamber door 6 is made of transparent material, allowing staff to observe the situation inside the testing chamber 1 through the chamber door 6.

[0043] In one embodiment, the outer surface of the collection box 503 is fixedly connected with a handle 7.

[0044] Pulling handle 7 can move collection box 503. Handle 7 protrudes from the outer surface of collection box 503, making it easy for staff to pull out collection box 503.

[0045] In summary, using the above-mentioned technical solution of this utility model, the glass curtain wall is placed in the testing box 1. After the electric push rod 204 in the testing box 1 is activated, the movable end of the electric push rod 204 pushes the clamping seat 301 to move, adjusting the distance between multiple sets of clamping seats 301 to facilitate the fixing of glass curtain walls of different sizes. Then, the glass curtain wall is placed between the clamping seat 301 and the clamping plate 304. Rotating the knob 303 drives the screw 302 to rotate. Through the threaded connection between the screw 302 and the clamping seat 301, the screw 302 and the clamping plate 304 slide within the clamping seat 301. At this time, the clamping seat 301 and the clamping plate 304 can clamp the glass curtain wall. Then, the fan is activated. The fan 401 draws outside air into the air duct 402. The gauge 403 on the air duct 402 is used to detect the wind speed and wind pressure inside the air duct 402. The air duct 402 blows the air onto the glass curtain wall inside the test box 1. The data of the gauge 403 when the glass curtain wall breaks is the wind pressure resistance of the glass curtain wall. The broken glass curtain wall fragments pass through the test box 1 and fall into the cavity 502 in the fixed base 501 at the bottom of the test box 1. The collection box 503 in the cavity 502 collects the glass curtain wall fragments. After pulling the collection box 503 to slide it out of the cavity 502 on the fixed base 501, the glass curtain wall fragments in the collection box 503 can be cleaned.

[0046] Through the above technical solution, 1. By adjusting the connection between component 2 and clamping component 3, with clamping component 3 located at the movable end of adjusting component 2, the extension and retraction of adjusting component 2 can drive clamping component 3 to move, thereby changing the distance between multiple sets of clamping components 3. This allows clamping components 3 to clamp and fix glass curtain walls of different sizes, making it more flexible to use. Furthermore, the center of multiple sets of clamping components 3 is at the same position as the axis of the air outlet of detection component 4, ensuring that the center of glass curtain walls of different sizes is always aligned with the detection component 4. 1. The air outlets are on the same axis to avoid deviations in the test results; 2. Through the connection between the clamping seat 301 and the clamping plate 304, the clamping plate 304 is slidably connected inside the clamping seat 301. When the knob 303 and the screw 302 are rotated, the screw 302 moves on the clamping seat 301. At the same time, the screw 302 pushes the clamping plate 304 to slide inside the clamping seat 301. The distance between the clamping seat 301 and the clamping plate 304 can be adjusted, which is convenient for fixing glass curtain walls of different thicknesses and is more flexible in use.
