Description
Technical Field
[0001] This invention relates to the field of materials testing technology, and in particular to a materials testing device and method for curtain walls. Background Technology
[0002] Modern curtain walls, as external building envelopes, have a significant impact on the environmental protection and energy conservation of the entire building. A building curtain wall is composed of a supporting structural system and panels, and is an external building envelope or decorative structure that can have a certain degree of displacement relative to the main structure and does not share the loads of the main structure. Currently, to ensure the quality and effectiveness of building curtain walls, performance testing is required after production, such as testing the strength of materials like the metal frame and glass.
[0003] A search revealed Chinese patent application number CN202220169974.2, which discloses a strength testing device for curtain wall materials. The device includes a housing with a partition between the left and right side walls. A drive motor is located at the center of the bottom of the housing. A first threaded rod is connected to the top of the drive motor. The top of the first threaded rod is connected to the bottom of the partition via a bearing. A first movable block is threaded onto the first threaded rod. Connecting rods are symmetrically hinged to both sides of the first movable block. First grooves are symmetrically provided on the partition on both sides of the first threaded rod. Guide rods are fixedly installed in both first grooves. A second movable block is slidably connected to each guide rod. The end of each connecting rod away from the first movable block is hinged to the bottom side wall of the corresponding second movable block. A fixing plate is provided at the top of each second movable block. The strength testing device for curtain wall materials in the aforementioned patent has the following shortcomings: the testing head is fixed on a hydraulic device, which makes the area where the testing head can contact the curtain wall material to be tested narrow. Since the position of the testing head cannot be changed, it is impossible to test the material over a large area, resulting in defects such as a small compressive strength testing range and inaccurate test results. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a material testing device and method for curtain walls.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A material testing device for curtain walls includes a base, a set of electric slide rails is provided on the top outer wall of the base, and a movable seat is slidably connected to the inner wall of the set of electric slide rails by a sliding block; a first fixed frame is fixed to the top outer wall of the base by bolts, a hydraulic mechanism electrically connected to a control module is fixed to the bottom surface of the first fixed frame by bolts, a pressure seat is fixed to the extension end of the hydraulic mechanism by bolts, and a pressure sensor communicatively connected to the control module is fixed to the bottom outer wall of the pressure seat by bolts. The bottom of the pressure seat is provided with a pressure area adjustment support, which consists of a drive structure and two support components that are identical in structure and are arranged in a corresponding manner. The drive structure includes a motor 2 fixedly connected to the inner wall of the bottom of the pressure seat, a secondary bevel gear rotatably connected to the inner walls of both sides of the pressure seat, an adjusting column fixedly connected to one end of the secondary bevel gear, and a main bevel gear rotatably connected to the inner wall of one side of the pressure seat and meshing with the outer wall of the secondary bevel gear. One end of the main bevel gear is connected to the output end of the motor 2 through a connecting shaft. The supporting assembly includes a movable block disposed on the outer wall of the adjusting column, two connecting columns rotatably connected to the bottom of the movable block, an extension plate rotatably connected to the bottom of the connecting column via a rotating shaft, a double channel disposed on the bottom outer wall of the pressure seat, and two guide grooves in opposite directions disposed on the bottom outer wall of the pressure seat. The two connecting columns are respectively inserted into the inner wall of the double channel, and the two extension plates are respectively within the enclosure of the two guide grooves. The bottom inner wall of the movable seat is equipped with a support assembly, which consists of an outer support plate and an inner support plate inserted within the area enclosed by the outer support plate. The bottom ends of both the outer and inner support plates are fixedly connected to sliding columns that form a sliding fit with the bottom inner wall of the movable seat. A top block is bolted to the top outer wall of the base near the first fixed frame. During the movement of the movable seat, the top block supports the bottom end of the outer support plate. During the forward and backward movement of the movable seat carrying the support assembly, the top block supports the inner support plate. When the electric slide rail drives the movable seat to move forward and backward, carrying the support assembly close to the top block, the top block will support the bottom end of the outer support plate or the bottom end of the inner support plate inside the outer support plate during the movement of the movable seat. This causes the top to move upward under the action of the sliding column, protruding from the surface of the movable seat and 'bridge-like' supporting the material on the movable seat. This allows the material to be pressed above the U-shaped pressure plate while keeping the bottom suspended. Then, the hydraulic mechanism controls the pressure seat to move downward, applying pressure and bending the middle position of the material.
[0006] Preferably, the sliding block and the electric slide rail are fixedly connected to the same folding cover on their corresponding sides.
[0007] Preferably, a set of positioning posts is fixedly connected to the bottom inner wall of the movable seat, the same U-shaped pressure plate is inserted into the outer wall of the set of positioning posts, and a strong spring is sleeved on the outer wall of the positioning posts. The two ends of the strong spring are respectively fixedly connected to the corresponding side of the U-shaped pressure plate and the movable seat. The bottom surface of the U-shaped pressure plate is equipped with an anti-slip layer.
[0008] Preferably: a first fixing frame is fixedly connected to the top outer wall of the base, and the same reinforcing rib is fixedly connected to one side outer wall of the first fixing frame and the top outer wall of the base; a hydraulic mechanism is fixedly connected to the bottom surface of the first fixing frame, and the top outer wall of the pressure seat is fixedly connected to the extension end of the hydraulic mechanism; a pressure sensor is fixedly connected to the bottom outer wall of the pressure seat.
[0009] Preferably, a second fixed frame is fixedly connected to the top outer wall of the base, and an adjustable pressure application part is disposed on one side of the second fixed frame; the adjustable pressure application part includes a motor fixed to one side outer wall of the second fixed frame by a support plate, two connecting plates respectively rotatably connected to the corresponding side of the second fixed frame, a limiting rod fixedly connected to the corresponding side of the two connecting plates, a threaded column rotatably connected to the corresponding side of the two connecting plates, and a fixing plate sleeved on the outer wall of the limiting rod, wherein the inner wall of the fixing plate is disposed on the outer wall of the threaded column, and one end of one of the connecting plates is connected to the output end of the motor by a coupling.
[0010] Preferably, a telescopic column is fixedly connected to the bottom outer wall of the fixed plate, a support block is fixedly connected to the extended end of the telescopic column, and a gravity ball is provided on the top inner wall of the support block through a connecting rope.
[0011] Preferably, a protective net is fixed to the top edge of the base; a control panel is fixed to one outer wall of the second fixing frame.
[0012] A method for testing curtain wall materials corresponding to a curtain wall material testing device includes the following steps: S1: Fix the curtain wall material to be tested onto the movable base; S2: Adjust the moving seat to the area of the compressive strength test, and test the compressive strength of the material through the pressure application seat; S3: Adjust the moving seat to the bending test area, adjust the spacing between the two support components according to the size of the material test range, and then test the bending capacity of the material through the pressure seat; S4: Adjust the speed and force of the impact material through the adjustable pressure part in order to perform local stress detection on the material on the moving seat that enters the local stress detection project area; S5: Remove the tested materials after the work is completed.
[0013] The beneficial effects of this invention are as follows: This invention features a pressure area adjustment support. A motor drives two secondary bevel gears to rotate via a main bevel gear, which in turn causes a change in the support assembly via an adjustment column. When the adjustment column rotates passively, it causes a moving block on it to move directionally along the dual channels under the constraint of a connecting column. As the two moving blocks move towards the center or sides, the same end of the two extension plates expands outwards, essentially extending beyond the protection range of the pressure seat, thus increasing the pressure area of the pressure seat. Alternatively, the extension plates may move backwards along the guide groove and 'retract' under the pull of the connecting column, effectively reducing the pressure area of the pressure seat. This allows for convenient adjustment of the pressure range of the pressure seat on the test material based on the actual testing situation, making it easy to use and improving testing effectiveness and accuracy.
[0014] This invention involves lifting a U-shaped pressure plate, placing the material to be tested on the movable seat, and then releasing it. At this time, the U-shaped pressure plate moves downward along the positioning column under the support of a strong spring until it is firmly attached to the surface of the material, thereby quickly pressing and fixing the material. After the material is quickly fixed, various tests such as compression resistance, bending resistance, and local stress are performed on the curtain wall material to determine whether the material strength meets the standards and to meet the requirements for wind pressure resistance and other performance during use. It is extremely convenient to use.
[0015] In this invention, a hydraulic mechanism drives a pressure seat to move downward until it is in close contact with the material surface and continuously applies pressure. When the pressure sensor detects that the pressure value has reached a set threshold, it transmits a signal to the control module so that the hydraulic mechanism can be stopped. This allows for the application of different detection pressures to the material, and the pressure-bearing capacity of the material can be obtained based on the material's changes.
[0016] This invention, by setting up a support assembly, allows the electric slide rail to move the moving seat back and forth, carrying the support assembly close to the top block. During the movement of the moving seat, the top block will successively support the bottom end of the outer support plate or the bottom end of the inner support plate inside the outer support plate, thereby causing it to move upward under the action of the sliding column. The top protrudes from the surface of the moving seat and supports the material on the moving seat in a 'bridge' manner, so that the material is pressed above the U-shaped pressure plate while keeping the bottom suspended. Then, the hydraulic mechanism controls the pressure seat to move downward, applying pressure and bending the middle position of the material. The bending pressure of the material is controlled by a pressure sensor to obtain the bending resistance test result based on the material's curvature change. By setting outer and inner support plates with different support ranges, it is easy to adjust the material to different bending areas as needed.
[0017] This invention features an adjustable pressure application section. Manually rotating the threaded column allows the fixed plate to move left and right under the constraint of a limiting rod, enabling adjustment of the fixed plate's position according to the material's required testing location. Then, a motor is started, driving the limiting rod to rotate via a connecting plate. This rotation, in turn, causes the fixed plate to rotate synchronously. As the fixed plate rotates, a telescopic column drives a gravity ball to revolve around the limiting rod. Since the bottom of the gravity ball extends beyond the material surface, it impacts the material surface after rotating more than half a revolution, at which point the motor stops operating. This allows for the detection of localized stress at different intensities and locations on the material based on the motor's rotation speed and the gravity ball's weight. Attached Figure Description

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments. Example
[0026] A method for testing materials used in curtain walls, such as Figure 1 As shown, it includes the following steps: S1: Fix the curtain wall material to be tested onto the movable seat 7; S2: Adjust the movable seat 7 to the area of the compressive strength test, and test the compressive strength of the material through the pressure application seat 10; S3: Adjust the moving seat 7 to move to the bending test area, adjust the support assembly spacing according to the size of the material test range, and then test the bending capacity of the material through the pressure seat 10. S4: Adjust the speed and force of the impact material through the adjustable pressure part so as to perform local stress detection on the material on the moving seat 7 that enters the local stress detection project area; S5: Once the work is finished, remove the tested materials.
[0027] In this embodiment, after the material is quickly fixed in place, various tests are conducted on the curtain wall material, such as compressive strength, bending strength, and local stress, to determine whether the material strength meets the standards and to satisfy the wind pressure resistance and other performance requirements during use. Example
[0028] An apparatus for testing materials using the method described in Example 1 for curtain walls, such as... Figure 1-3 As shown, the device includes a base 1, with a set of electric slide rails on the top outer wall of the base 1. The inner wall of the set of electric slide rails is slidably connected to a hook-shaped movable seat 7 for carrying the material to be tested via sliding blocks. Preferably, the set of sliding blocks and the corresponding side of the electric slide rails are fixed with the same folding cover 9 by bolts to prevent powder generated during the test from falling into the electric slide rails. After the material to be tested is placed on the movable seat 7, the electric slide rails are activated, and the movable seat 7 drives the material to move back and forth to perform different strength tests on the material.
[0029] Furthermore, a set of positioning posts 702 are fixed to the bottom inner wall of the movable seat 7 by bolts. The outer wall of the set of positioning posts 702 is fitted with the same U-shaped pressure plate 701, and a strong spring 703 is sleeved on the outer wall of the positioning posts 702. The two ends of the strong spring 703 are respectively welded to the corresponding side of the U-shaped pressure plate 701 and the movable seat 7. Figure 3 As shown; Preferably, the bottom surface of the U-shaped pressure plate 701 is bonded with an anti-slip layer to improve the friction between the U-shaped pressure plate 701 and the surface of the material being pressed; lift the U-shaped pressure plate 701, place the material to be tested on the movable seat 7 and then release it. At this time, the U-shaped pressure plate 701 moves down along the positioning post 702 under the support of the strong spring 703 until it is firmly attached to the surface of the material, thereby quickly pressing and fixing the material, which is extremely convenient to use.
[0030] To facilitate testing the compressive strength of materials; such as Figure 1 and Figure 5-7 As shown, the top outer wall of the base 1 is fixed with a first fixing frame 2 by bolts, the bottom surface of the first fixing frame 2 is fixed with a hydraulic mechanism 11 electrically connected to the control module by bolts, the extension end of the hydraulic mechanism 11 is fixed with a pressure seat 10 by bolts, and the bottom outer wall of the pressure seat 10 is fixed with a pressure sensor 18 communicatively connected to the control module by bolts. Preferably, the hydraulic mechanism 11 uses existing technology, which will not be described in detail here; when the material is brought to the first fixed frame 2 by the movable seat 7, especially below the pressure seat 10, the hydraulic mechanism 11 is activated to drive the pressure seat 10 to move down until it is in close contact with the material surface and continuously applies pressure. When the pressure sensor 18 detects that the pressure value has reached the set threshold, it transmits a signal to the control module so as to control the hydraulic mechanism 11 to stop, so as to apply different detection pressures to the material and obtain the pressure bearing capacity detection result of the material according to the material change.
[0031] Preferably, one side outer wall of the first fixing frame 2 and the top outer wall of the base 1 are fixed with the same reinforcing rib 201 to improve the stability of the first fixing frame 2. Furthermore, the bottom end of the pressure seat 10 is provided with a pressure area adjustment support for adjusting the stress area of the material. The pressure area adjustment support consists of a drive structure and two support components with the same structure and corresponding arrangement, which are moved back and forth by the drive structure. The drive structure includes a second motor 15 fixed to the inner wall of the bottom of the pressure seat 10 by bolts, a secondary bevel gear 1501 rotatably connected to the inner walls of both sides of the pressure seat 10, an adjustment column 1502 fixed to one end of the secondary bevel gear 1501 by bolts, and a main bevel gear 1503 rotatably connected to the inner wall of one side of the pressure seat 10 and meshing with the outer wall of the secondary bevel gear 1501. One end of the main bevel gear (1503) is connected to the output end of the second motor 15 through a connecting shaft. When the second motor 15 is started, it drives the two secondary bevel gears 1501 to rotate through the main bevel gear 1503, which in turn drives the support components to change through the adjustment column 1502.
[0032] Furthermore, the supporting assembly includes a movable block 16 connected to the outer circumference of the adjusting column 1502 by a thread, two connecting columns 1601 rotatably connected to the bottom of the movable block 16, an extension plate 17 rotatably connected to the bottom of the connecting column 1601 by a rotating shaft, a double channel 1001 opened on the bottom outer wall of the pressure seat 10, and two guide grooves 1002 semi-opened on the bottom outer wall of the pressure seat 10 in opposite directions. The two connecting columns 1601 are respectively inserted into the inner wall of the double channel 1001, and the two extension plates 17 are respectively within the enclosure of the two guide grooves 1002. When the adjusting column 1502 rotates passively, it drives the moving block 16 on it to move back and forth along the double channel 1001 under the restriction of the connecting column 1601. When the two moving blocks 16 move towards the middle, the outer plate 17 will move forward along the guide groove 1002 under the pushing of the connecting column 1601 and then expand outward, so that the two parallel outer plates 17 expand outward at the same end until they basically extend out of the protection range of the pressure seat 10, thereby increasing the pressure area of the pressure seat 10. Conversely, when the two moving blocks 16 move outward, the outer plate 17 will move backward and 'retract' along the guide groove 1002 under the pulling of the connecting column 1601, so that the pressure area of the pressure seat 10 is effectively reduced and it is convenient to use.
[0033] To facilitate the testing of a material's bending resistance; such as Figure 1-4 As shown, the bottom inner wall of the movable seat 7 is provided with a support assembly, which consists of an outer support plate 14 and an inner support plate 1401 inserted within the area covered by the outer support plate 14. The bottom ends of the outer support plate 14 and the inner support plate 1401 are both welded with sliding columns 1402 that form a sliding fit with the bottom inner wall of the movable seat 7. Furthermore, a top block 8 is bolted to the top outer wall of the base 1 near the first fixing frame 2; Preferably, the top horizontal line of the top block 8 is slightly smaller than the bottom horizontal line of the movable seat 7; Preferably, when the support assembly is not under stress, its top horizontal line is basically close to the top outer wall of the movable seat 7. After the electric slide rail is activated, the movable seat 7 is moved back and forth, carrying the support assembly close to the top block 8. During the displacement of the movable seat 7, the top block 8 will support the bottom end of the outer support plate 14, which is located on the outer edge. This will cause the top block to move upward under the action of the slide column 1402, protruding from the surface of the movable seat 7 and 'bridge-like' supporting the material on the movable seat 7. This allows the material to be pressed above the U-shaped pressure plate 701 while keeping the bottom suspended. Then, the hydraulic mechanism 11 controls the pressure seat 1. The material is lowered to apply pressure and bend at the middle position. The bending pressure is controlled by the pressure sensor 18 to obtain the bending resistance test result based on the material curvature change. When the moving seat 7 moves back and forth carrying the support assembly, the top block 8 supports the inner support plate 1401 and also 'bridges' the material on the moving seat 7 to conduct bending tests. By setting the outer support plate 14 and inner support plate 1401 with different support ranges, it is convenient to adjust the material to different bending areas as needed.
[0034] To facilitate the detection of localized stress in materials; such as Figure 1-2As shown, a second fixed frame 3 is bolted to the top outer wall of the base 1 away from the first fixed frame 2. An adjustable pressure part is provided on one side of the second fixed frame 3. The adjustable pressure part includes a motor 12 bolted to the outer wall of one side of the second fixed frame 3 by a support plate, two connecting plates 1203 respectively rotatably connected to the corresponding side of the second fixed frame 3, a long strip-shaped limiting rod 1202 bolted to the corresponding side of the two connecting plates 1203, a threaded column 1201 rotatably connected to the corresponding side of the two connecting plates 1203, and a fixing plate 13 sleeved on the outer wall of the limiting rod 1202. The inner wall of the fixing plate 13 is threaded to the outer wall of the threaded column 1201. One end of one of the connecting plates 1203 is connected to the output end of the motor 12 by a coupling. Preferably, motor 12 is electrically connected to the control module; manually rotating the threaded column 1201 causes the fixing plate 13 to move left and right under the restriction of the limiting rod 1202, so as to adjust the position of the fixing plate 13 according to the material to be detected. Then, motor 12 is started to drive the limiting rod 1202 to rotate through the connecting plate 1203, thereby causing the fixing plate 13 to rotate synchronously under its structural drive.
[0035] Furthermore, a telescopic column 1301 is bolted to the bottom outer wall of the fixed plate 13, and a support block is bolted to the extended end of the telescopic column 1301. A gravity ball 6 is attached to the top inner wall of the support block by a connecting rope. When the fixed plate 13 rotates, the telescopic column 1301 drives the gravity ball 6 to rotate around the limit rod 1202. Since the bottom end of the gravity ball 6 extends beyond the material surface, it will hit the material surface after rotating more than half a revolution. Then, the motor 12 is controlled to stop working, which makes it convenient to perform local stress detection on the material at different forces and locations based on the speed of the motor 12 and the weight of the gravity ball 6.
[0036] Preferably, the telescopic column 1301 consists of a sleeve and an extension column inserted into the inner wall of the sleeve. The inner walls of both the sleeve and the extension column are provided with equidistant insertion holes from top to bottom. The inner walls of the insertion holes on the sleeve and the extension column that are in overlapping positions are connected by the same pin through threads. Before the test, the extension length of the extension column is adjusted in the sleeve according to the size of the gravity ball 6 and the position of the top surface of the fixed material on the moving seat 7. Then, the pin is inserted into the inner walls of the two overlapping insertion holes to fix the working length of the telescopic column 1301 so that the gravity ball 6 can contact the material surface.
[0037] Furthermore, a protective net 5 is bolted to the top edge of the base 1 to prevent broken materials from splashing out; a control panel 4, which is connected to the control module, is bolted to one side of the outer wall of the second fixing frame 3; this facilitates the operation of staff and allows them to understand the specific details of the testing items.
[0038] In this embodiment, when in use, lift up the U-shaped pressure plate 701, place the material to be tested on the movable seat 7 and then release. At this time, the U-shaped pressure plate 701 moves down along the positioning post 702 under the support of the strong spring 703 until it is firmly attached to the surface of the material, thereby quickly pressing and fixing the material.
[0039] Then, the electric slide rail is activated, and the material is moved back and forth via the moving seat 7. When the material is brought to the first fixed frame 2, especially below the pressure seat 10, the motor 15 is activated first, and the main bevel gear 1503 drives the two auxiliary bevel gears 1501 to rotate. Then, the adjusting column 1502 drives the support assembly to change. When the adjusting column 1502 rotates passively, it drives the moving block 16 on it to move back and forth along the double channel 1001 under the restriction of the connecting column 1601. When the two moving blocks 16 move towards the middle, the outer plate 17 will be connected to the connecting column. Under the pushing force of 1601, the guide groove 1002 moves forward and then expands outward, causing the two parallel extension plates 17 to expand outward from the same end until they basically extend beyond the protection range of the pressure seat 10, thereby increasing the pressure area of the pressure seat 10. Then, the hydraulic mechanism 11 is activated to drive the pressure seat 10 downward until it is in close contact with the material surface and continuously applies pressure. When the pressure sensor 18 detects that the pressure value has reached the set threshold, it transmits a signal to the control module to stop the hydraulic mechanism 11, which facilitates the application of different test pressures to the material. After the pressure test is completed, the motor 15 is activated in reverse, causing the two moving blocks 16 to move outward. This causes the guide groove 1002 to move backward and retract under the pulling force of the connecting column 1601, effectively reducing the pressure area of the pressure seat 10.
[0040] When the electric slide rail drives the moving seat 7 to move back and forth and carry the support assembly close to the top block 8, the top block 8 will support the bottom end of the outer support plate 14 or the bottom end of the inner support plate 1401 inside the outer support plate 14 during the displacement of the moving seat 7. This will cause the top block 8 to move upward under the action of the sliding column 1402, with the top protruding from the surface of the moving seat 7 and 'bridge-like' supporting the material on the moving seat 7. This will keep the bottom of the material suspended while it is pressed above the U-shaped pressure plate 701. Then, the hydraulic mechanism 11 controls the pressure seat 10 to move downward, applying pressure and bending to the middle position of the material. The pressure sensor 18 controls the bending pressure of the material so as to obtain the bending resistance test result based on the change of the material's curvature.
[0041] Beforehand, a gravity ball 6 of appropriate weight is fixed to the support block. Based on the size of the gravity ball 6 and the position of the top surface of the material fixed on the moving seat 7, the extension length of the extension column is adjusted inside the sleeve. Then, a pin is inserted into the inner walls of the two overlapping insertion holes to fix the length of the telescopic column 1301. Next, the threaded column 1201 is manually rotated, causing the fixing plate 13 to move left and right under the restriction of the limiting rod 1202. This allows the position of the fixing plate 13 to be adjusted according to the required inspection position of the material. Finally, the motor 12 is started via the connecting plate 12. 03 drives the limiting rod 1202 to rotate, which in turn causes the fixing plate 13 to rotate synchronously. When the fixing plate 13 rotates, it will drive the gravity ball 6 to rotate around the limiting rod 1202 as a fixed point via the telescopic column 1301. Since the bottom end of the gravity ball 6 extends beyond the material surface, it will hit the material surface after rotating more than half a revolution. Then, the motor 12 is controlled to stop working, so that the local stress detection of the material at different forces and positions can be realized according to the speed of the motor 12 and the weight of the gravity ball 6.
