Description

Technical Field

[0001] This utility model belongs to the field of curtain wall testing technology, specifically relating to a testing device for building curtain walls. Background Technology

[0002] Building curtain walls, also known as suspended walls, are building envelope structures that do not bear the load and force of the main structure. Because curtain walls are exposed to the outside environment for a long time, relevant tests need to be carried out to ensure their reliability. Among them, wind pressure resistance testing is particularly important.

[0003] In related prior art, such as Chinese Patent No. CN221993210U, a wind pressure resistance testing device for glass curtain walls is disclosed, which includes 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 slot for the curtain wall to be engaged is provided on the inner wall opposite the side wall where the insertion port is located. The curtain wall is fixedly installed inside the static pressure chamber under the constraint of the sliding groove and the slot. A sealing plate is rotatably provided on the side of the insertion port facing outwards. The sliding groove, slot, and insertion port divide the interior of the static pressure chamber into a testing area and a detection area. An air pump is fixedly installed in the testing area inside the static pressure chamber, with the air outlet facing the curtain wall. A displacement sensor is slidably installed in the detection area inside the static pressure chamber, with the detection end of the displacement sensor facing the curtain wall. This solution can detect the wind pressure resistance of curtain walls and quickly replace the curtain wall samples being tested, making it highly efficient and fast.

[0004] However, in actual use, because the above scheme has a perforated grid at the bottom of the static pressure box, wind pressure can enter the back of the curtain wall through the perforated grid-collection box-perforated grid, thus interfering with the wind pressure resistance deformation of the curtain wall, and consequently causing the final measured wind pressure resistance strength of the curtain wall to be inaccurate. Utility Model Content

[0005] The present invention aims to provide a testing device for building curtain walls to solve the problem mentioned above that the existing testing structures are inaccurate in testing the wind pressure resistance of curtain walls.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a detection device for building curtain walls, comprising...

[0007] The static pressure chamber has a test chamber and a collection chamber inside. The bottom of the test chamber is provided with multiple slag discharge troughs, which are connected to the collection chamber. A collection box is provided inside the collection chamber.

[0008] The partition is slidably inserted into the static pressure box, and the partition closes the slag discharge chute.

[0009] The clamping mechanism is installed inside the test chamber;

[0010] A wind pressure mechanism, installed on the static pressure box and used to control the air pressure in the test chamber;

[0011] A detection mechanism, installed in the test chamber.

[0012] The principle and effect of this technical solution:

[0013] 1. Through the setting of the partition, the connection status between the test chamber and the collection chamber can be controlled according to the actual situation, thereby avoiding the interference of the curtain wall deformation caused by the wind pressure reaching the back of the curtain wall to be tested from the slag discharge groove, and improving the detection accuracy of the wind pressure resistance strength.

[0014] 2. After the curtain wall is broken, the slag of the curtain wall can be collected through the slag discharge groove, which is easy to maintain the test chamber. And during the test, the slag discharge groove can be closed by inserting the partition, so that the air pressure on one side of the curtain wall close to the wind pressure mechanism does not interfere with the air pressure on the side of the curtain wall far from the wind pressure mechanism.

[0015] The present utility model is further provided that: the clamping mechanism includes a first baffle, a second baffle, a roller and a control unit. The cross-sections of the first baffle and the second baffle are both in the shape of a "hui" character. The first baffle is fixed in the test chamber. Rotating rollers are installed at both the upper and lower ends of the side wall of the first baffle. The rollers are located on the side of the first baffle away from the wind pressure mechanism. The second baffle is slidably fitted in the test chamber and is slidably sleeved on the rollers. The control unit is used to control the distance of the second baffle relative to the first baffle. A placement opening is provided on the side wall of the static pressure box. The position of the placement opening corresponds to the first baffle, and the second baffle is slidably fitted with the placement opening. A closing plate is installed on the side wall of the static pressure box.

[0016] The principle and effect of this technical solution: Through the setting of the first baffle, the second baffle and the rollers, the curtain wall can be fed between the first baffle and the second baffle by small contact and rolling, reducing the resistance when the curtain wall is placed. And the first baffle and the second baffle limit the curtain wall, making the placement of the curtain wall more stable. By controlling the position of the second baffle through the control unit, the curtain wall can be stably clamped and can adapt to curtain walls of different thicknesses. The setting of the placement opening and the closing plate makes the placement of the curtain wall easier, and the closing plate can seal the placement opening to prevent the curtain wall from splashing out when it is broken. Through the "hui" character shape setting, the four sides of the curtain wall can be pressed and fixed by the first baffle and the second baffle, and the middle part bears the air pressure, avoiding the outflow of gas from the edge of the curtain wall and making the air pressure more stable and controllable.

[0017] The present utility model is further provided that: the control unit includes a control rod, a turntable, a connecting plate and a connecting rod. The control rod is rotatably installed on the outer wall of the static pressure box. The end of the control rod is connected to the turntable. The connecting plate is threadedly sleeved on the control rod. The connecting rod is fixed on the connecting plate. The connecting rod is slidably inserted into the static pressure box, and the end of the connecting rod extends to be connected to the second baffle.

[0018] The principle and effect of this technical solution: The connecting plate and the second baffle are connected by a connecting rod, so that the second baffle and the connecting plate indirectly become a whole and can move synchronously. The connecting rod limits the connecting plate and prevents it from rotating. Then, by rotating the control rod by the turntable, the connecting plate can be controlled to slide on the control rod, thereby controlling the distance between the second baffle and the first baffle. This allows the positions of the first baffle and the second baffle to be adjusted according to the thickness of the curtain wall, thus adapting to more types of curtain walls for testing.

[0019] The present invention is further configured such that: a slide rail is installed on the side wall of the static pressure box, the slide rail is located at the upper and lower ends of the placement opening, the sealing plate is slidably engaged with the slide rail, and the sealing plate is used to close the placement opening.

[0020] The principle and effect of this technical solution: By setting up the slide rail, the sealing plate can slide relative to the static pressure box, thereby closing or opening the placement port.

[0021] The present invention is further configured such that: a limiting plate is fixed to the side wall of the first baffle, the limiting plate is slidably inserted into the second baffle, and the limiting plate is located at the end of the first baffle away from the placement opening.

[0022] The principle and effect of this technical solution: By setting the limiting plate, it is easier for the user to position the curtain wall when installing it between the first baffle and the second baffle, so that the curtain wall can be accurately clamped by the first baffle and the second baffle.

[0023] The present invention is further configured such that: the detection mechanism includes a pressure detector and a displacement detector, the pressure detector is installed in the test chamber and is located on the side of the first baffle close to the air pressure mechanism, and a mounting rod is fixed on the side of the second baffle away from the first baffle, and the displacement detector is installed on the mounting rod.

[0024] The principle and effect of this technical solution: The air pressure detector can detect the air pressure on the side of the first baffle close to the wind pressure mechanism, thereby detecting the air pressure on the curtain wall. The displacement detector can detect the deformation under pressure, thereby obtaining the compressive strength of the curtain wall. Furthermore, the displacement detector and the second baffle are connected as a whole by the mounting rod, so that the position of the displacement detector can be adjusted synchronously with the second baffle, thus eliminating the need to control the position of the displacement detector separately.

[0025] The present invention is further configured such that: the air pressure mechanism includes a booster pump and an air extraction pump, both of which are installed on the side wall of the static pressure box.

[0026] The principle and effect of this technical solution: By setting up a booster pump and an air pump, the maximum wind pressure resistance and minimum negative pressure resistance of the curtain wall can be tested. By pressurizing the inside of the test chamber, the wind pressure resistance of the curtain wall can be tested. By evacuating the air pump, the air pressure inside the test chamber can be reduced, thereby testing the negative pressure resistance of the curtain wall. Attached Figure Description

[0041] Example:

[0042] As attached Figures 1-4As shown, this utility model discloses a testing device for building curtain walls, including a static pressure box 101, a partition plate 201, a clamping mechanism, an air pressure mechanism, and a testing mechanism. The static pressure box 101 is an essential accessory for air supply systems to reduce dynamic pressure, increase static pressure, stabilize airflow, and reduce airflow vibration. It can make the air supply effect more ideal and is a commonly used box in pressurization or depressurization testing. The static pressure box 101 has a test chamber 104 and a collection chamber 105 inside. The test chamber 104 is located above the collection chamber 105, and multiple slag discharge grooves 106 are spaced apart at the bottom of the test chamber 104. The slag discharge trough 106 is connected to the collection chamber 105. A collection box 107 is provided in the collection chamber 105. The collection box 107 is slidably engaged with the collection chamber 105. The slag discharge trough 106 is vertically opened. A partition 201 is horizontally slidably inserted into the static pressure box 101. The partition 201 closes the slag discharge trough 106. A placement opening 102 is opened on the side wall of the static pressure box 101. The box door 103 of the static pressure box 101 is located on the side opposite to the placement opening 102. The box door 103 is a transparent door for easy observation. The setting of the box door 103 makes it easy to open the test chamber 104 for cleaning and maintenance.

[0043] By controlling the baffle plate 201, the flow of the slag discharge trough 106 can be controlled, thereby performing the functions of slag discharge or sealing detection according to actual needs.

[0044] The clamping mechanism includes a first baffle 301, a second baffle 302, a rotating roller 303, and a control unit. The cross-sections of the first baffle 301 and the second baffle 302 are both U-shaped. The first baffle 301 is fixed inside the test chamber 104, and the air on the side of the first baffle 301 from the air pressure mechanism can only flow out through the middle gap of the first baffle 301 or through the slag discharge trough 106. The upper and lower ends of the side wall of the first baffle 301 are equipped with rotating rollers 303, which are located on the side of the first baffle 301 away from the air pressure mechanism. The second baffle 302 is slidably fitted inside the test chamber 104 and is slidably fitted onto the rotating roller 303. The position of the placement port 102 corresponds to that of the first baffle 301, and the second baffle 302 is slidably fitted with the placement port 102.

[0045] A limiting plate 304 is fixed to the side wall of the first baffle 301. The limiting plate 304 is slidably inserted into the second baffle 302, and the limiting plate 304 is located at the end of the first baffle 301 away from the placement opening 102. By controlling the maximum size that the curtain wall 801 can extend into, it is easier to position the curtain wall 801, so that the curtain wall 801 can be evenly exposed in the gap of the first baffle 301, that is, the curtain wall 801 can be evenly covered by the first baffle 301 on all sides.

[0046] The roller 303 reduces friction on the curtain wall 801 when it is placed between the first baffle 301 and the second baffle 302 through the placement port 102, making it easier to push the curtain wall 801. The control unit includes a control rod 401, a turntable 402, a connecting plate 403, and a connecting rod 404. The control rod 401 is rotatably mounted on the outer wall of the static pressure box 101, and the end of the control rod 401 is connected to the turntable 402. The connecting plate 403 is threaded onto the control rod 401, and the connecting rod 404 is fixed to the connecting plate 403. The connecting rod 404 is slidably inserted into the static pressure box 101, and the end of the connecting rod 404 extends to connect with the second baffle 302.

[0047] The side wall of the static pressure box 101 is equipped with a slide rail 501, which is located at the upper and lower ends of the placement port 102. The sealing plate 502 is slidably engaged with the slide rail 501 and is used to close the placement port 102.

[0048] The testing mechanism includes a pressure detector 601 and a displacement detector 602. The pressure detector 601 is installed inside the test chamber 104 and is located on the side of the first baffle 301 closest to the air pressure mechanism. A mounting rod 603 is fixed on the side of the second baffle 302 away from the first baffle 301, and the displacement detector 602 is mounted on the mounting rod 603. The pressure detector 601 and displacement detector 602 are commonly used testing instruments in the inspection of the curtain wall 801, and both are commercially available products, so they will not be described in detail here. The displacement detector 602 can be a laser rangefinder or other testing device. When inspecting the glass curtain wall 801, a contact displacement measuring instrument or other testing device is used accordingly.

[0049] The air pressure mechanism includes a booster pump 701 and an air extraction pump 702. Both the booster pump 701 and the air extraction pump 702 are installed on the side wall of the static pressure box 101. The booster pump 701 can be a Feintech ZTD pneumatic booster pump 701, and the air extraction pump 702 can be a Haixun THD121-43A1-DA air extraction pump 702.
