Description

Technical Field

[0001] This invention belongs to the field of testing equipment technology, and in particular relates to a device for testing the compressive strength of building structures and its usage method. Background Technology

[0002] When a building is constructed, its physical structure is built first. The physical structure of a building refers to its physical structure, including columns, walls, beams, slabs, and foundations. These components are interconnected to form a whole that supports the entire building. The physical structure is the skeleton of the building, and its stability, safety, and reliability are directly related to the building's service life and safety.

[0003] After construction is completed, the building structure needs to be tested to ensure the overall safety and quality of the building. Existing testing equipment only has simple testing methods and requires manual hand-held operation. Testing at higher elevations requires the installation of complex support structures to ensure the stability of the testing equipment, which seriously affects the efficiency of the testing and is also prone to abnormal test data due to external factors such as unstable support structures or hand-held operation.

[0004] Patent application CN202022458309.9 discloses a device for testing the compressive strength of building structures, which includes an automatic measuring device and a handle for easy carrying. However, this device requires drilling and fixation via a fixed post, making it unsuitable for testing columnar structures or flat surfaces where drilling is not possible. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a device for testing the compressive strength of building structures and its usage method.

[0006] The present invention is achieved through the following technical solutions.

The connecting column is provided with a shaft hole and a boss. The connecting column is hinged to the supporting assembly through the shaft hole.

[0010] Preferably, the positioning component includes a positioning block and a first elastic element. The positioning block is snapped into a second groove on the main frame component. A first slot is provided inside the positioning block. The first elastic element is provided on the positioning block. A protruding strip is provided at the outer end of the positioning block.

[0011] Preferably, the support assembly includes a support frame and a support rod. The support frame is hinged to the connecting column through a shaft hole. The support rod is connected to the outer end of the support frame. A connector is provided at the end of the support rod. A reinforcing sleeve is slidably connected to the connector. Two sets of positioning plates are slidably installed on the outer wall of the support frame. The positioning plates are slidably connected to the connecting column through bosses.

[0012] Preferably, the fixing component includes a swing block and a fixing column. The swing block is rotatably mounted on the main frame assembly, and the fixing column is sleeved on the swing block. The bottom of the fixing column is set as a ball head, the top of the fixing column is set as a corrugated head, and a limiting platform is provided on the fixing column. A second elastic element is installed between the limiting platform and the swing block.

[0013] Preferably, the external component includes an external plate and a reinforcing plate. A slider is provided on the external plate, and the external plate is slidably mounted on the slide groove via the slider. Bolts are installed on the external plate, and a reinforcing plate is provided on the outer side of the external plate. A snap-fit ​​groove is provided on one side of the external plate, and a protrusion is provided on the inner wall of the snap-fit ​​groove.

[0014] Preferably, the support assembly includes a support plate with a mounting hole in the center. The testing device and fasteners are connected to the support assembly through the mounting hole. A second slot is provided on the outer wall of the support plate, and a threaded or fixing groove is provided on the inner wall of the mounting hole. The fixing groove corresponds to the snap-fit ​​protrusion on the outer wall of the testing device. The testing device is connected to the support assembly through the fixing groove, and the fasteners are threadedly connected to the support assembly through the thread of the mounting hole, so that the fasteners can be adjusted on the support plate.

[0015] A method for using a device for testing the compressive strength of a building structure includes the steps of testing the compressive strength of the building's walls and columns.

[0016] The steps for testing the compressive strength of a wall include:

[0017] A1: After determining the location of the wall to be tested, start assembling the compressive strength testing device. The bearing component is installed in the rectangular opening and fixed by the fixing component. The testing equipment is installed on the bearing component. The snap-fit ​​protrusion at the end of the testing equipment is installed to correspond to the fixing groove of the bearing plate.

[0018] A2: Install the connecting frame on the main frame assembly. The connecting rod extends directly into the main frame assembly. While installing the upper and lower sets of connecting frames, connect the outer sleeve to the connecting column and engage the connecting rod with the positioning assembly.

[0019] A3: The connecting column is hinged to the support frame through the shaft hole, and the sliding positioning plate is moved to the boss to increase the stability of the contact between the support component and the connecting component. When the support rod needs to be lengthened, other support rods are connected to the end of the support rod through the connector, and then the reinforcing sleeve is slid to the connection between the support rods.

[0020] A4: Place the end of the extended support rod against another wall symmetrical to the wall being tested, or swing the hinge of the support assembly and the connecting column downwards so that the end of the support rod is fixed to the ground, and then test the wall using the testing equipment.

[0021] The steps for testing the compressive strength of a column include:

[0022] B1: When testing the columns of a building, since the columns are set to be open on four or three sides, if the compressive strength testing device is already installed as in step A4, the connecting components and support components need to be disassembled.

[0023] B2: Install the external plates on the side plates on both sides of the main frame, and then rotate the bolts of the external plates to fix the external plates stably at both ends of the main frame assembly.

[0024] B3: Install the load-bearing components at the snap-fit ​​slots on both sides of the outer plate. Install fasteners on the load-bearing components on one side and install the testing equipment on the load-bearing components on the other side. Move the main frame assembly to the position on the column where testing is required, and rotate the outer end of the fastener until its inner end contacts the column, so that the entire device is fixed on the column, and the testing can begin.

[0025] The beneficial effects of this invention are as follows:

[0026] 1. In this invention, a fixing plate is directly provided at the middle position of the main frame assembly, allowing the load-bearing component to be snapped into place. Fixing components are added to both the upper and lower ends of the main frame assembly where the load-bearing component is installed, providing a secure fixation and making the load-bearing component more stable in the middle position of the main frame assembly. Two sets of connecting components are installed at the outer ends of the main frame assembly. After installation, these connecting components are secured by positioning components to prevent them from falling off. Supporting components are hinged to the outer ends of the connecting components, allowing for simultaneous connection of multiple fixing components or direct tilting of the support components. The dynamic jack is fixed on the ground, allowing the main frame assembly to be fixed at any height. This makes the testing equipment on the load-bearing components in the middle of the main frame assembly faster and more efficient. When testing narrower sections such as columns, external components are directly installed at both ends of the main frame assembly. Each set of external components can be equipped with a load-bearing component. The side that does not need to be tested is fitted with a fastening device. Rotating the fastening device fixes the entire device in the designated position on the column. At this point, the testing equipment is installed on the load-bearing component at the testing side for testing. The same individual building materials can also be tested in this way. Simply readjust the position of the fastening device to fit the material being tested.

[0027] 2. The present invention provides a rectangular opening in the middle of the main frame and fixing plates at the top and bottom of the opening to facilitate the installation of subsequent load-bearing components. The fixing plates are provided with a first groove to facilitate the direct sliding and snap-fit ​​installation of the load-bearing components. Side plates are provided at the front and rear ends of the main frame, and horizontal sliding grooves are provided at the outer ends of the side plates to allow external components to be slidably installed through the sliding grooves of the side plates, thereby realizing the effect of multiple detection methods of the equipment.

[0028] 3. The connecting frame of this invention is configured to be installed on the main frame assembly, thus setting the connecting frame into a triangular structure, making the connecting frame more stable after being fixed on the main frame assembly. The two sets of connecting rods at the end of the connecting column are set as the main connecting components and the main frame assembly for connection and fixing. The buffer set at the end of the connecting rod allows the bottom of the connecting rod to easily contact the positioning component for fixing. The vertical outer sleeve at the end of the connecting frame is directly installed at the upper and lower positions of the connecting column, so that the two sets of connecting frames can be uniformly installed on the connecting column. The shaft hole on the connecting column has the function of facilitating the connection of the external support component, realizing the position fixing function of the device.

[0029] 4. After the connecting rod of the connecting component of the present invention is installed on the main frame component, the end of the connecting rod will contact the first slot of the positioning block, allowing the end of the connecting rod to directly engage with the first slot, thereby achieving the effect of stably fixing the connecting component to the main frame component. When disassembling the connecting component, simply touch the protruding strip at the outer end of the positioning block and slide the positioning block outwards, allowing the positioning block slot to disengage from the connecting rod, thus achieving the disassembly of the connecting component.

[0030] 5. This invention provides support rods at the outer ends of the support frame, with connectors at the ends of the support rods, allowing direct connection between the support rods. The connected support rods can be reinforced with sliding sleeves, positioning the sleeves at the connection points of the support rods, thus ensuring the stability of the support rod connection. The extended support rods can then be pressed against the wall at the other end, achieving overall device fixation. Simultaneously, the support frame can swing on the connecting column, allowing the outer support rods to directly contact the ground. A positioning plate slidably installed at the outer end of the support frame ensures better contact with the connecting column, further enhancing the overall stability of the support assembly.

[0031] 6. During installation, the load-bearing component of the main frame assembly of this invention slides onto the fixed plate. To ensure the load-bearing component is stably positioned on the fixed plate, the fixed components are directly installed at the upper and lower ends of the main frame assembly. The swing block can swing on the main frame assembly, causing the fixed column of the swing block to be pulled out and pressed against the outer end. This allows for quick installation and disassembly of the load-bearing component. When it is necessary to fix the load-bearing component, simply hold the corrugated head and pull the fixed column outward, then swing the fixed column back to its original position via the swing block. At this time, the spring will cause the fixed column to extend into the main frame assembly, pressing against the load-bearing component, thus fixing the position of the load-bearing component. This makes the load-bearing component more stable after installation, facilitating subsequent testing.

[0032] 7. When inspecting column-like structures in buildings, this invention directly installs reinforcing plates on the side plates at both ends of the main frame assembly. After installation, the reinforcing plates are fixed in position by bolts. The external assembly and the main frame assembly form a clamping frame, allowing the external assembly to be held at both ends of the column. After the load-bearing component is installed at the snap-fit ​​groove of the external plate, pressure is applied to the external plate, thereby setting the outer end of the external plate with a reinforcing plate, increasing the stability of the external plate. The protruding structure at the snap-fit ​​groove allows the load-bearing component installed at the snap-fit ​​groove to limit its position, enabling the device to inspect the building column.

[0051] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0052] Example:

[0053] like Figures 1 to 10 As shown, a structural compressive strength testing device includes a main frame assembly 1, a connecting assembly 2, a positioning assembly 3, a support assembly 4, an external assembly 6, and a load-bearing assembly 7. The connecting assembly 2 is installed on the right side of the main frame assembly 1, and the support assembly 4 is hinged to the outer end of the connecting assembly 2. The positioning assembly 3 is installed at the connection between the main frame assembly 1 and the connecting assembly 2. The load-bearing assembly 7 is snapped onto the main frame assembly 1. A fixing assembly 5 is installed on the main frame assembly 1. External assemblies 6 are installed at both the front and rear positions of the main frame assembly 1. The load-bearing assembly 7 is installed on the external assembly 6, and a testing device 8 and fasteners 9 are respectively installed on the load-bearing assembly 7.

[0054] The main frame assembly 1 includes a main frame 101 and side clamping plates 102. The main frame 101 is a rectangular structure with a rectangular opening 104 in the middle. Fixing plates 103 are provided at the upper and lower ends of the rectangular opening 104. The fixing plates 103 have first grooves 105. The rectangular opening 104 and the fixing plates 103 facilitate the installation of the subsequent load-bearing assembly 7. The first grooves 105 on both sides of the fixing plates 103 facilitate the sliding and snapping installation of the load-bearing assembly 7. Side clamping plates 102 are provided on both sides of the main frame 101. The outer end face of the side clamping plates 102 is provided with a sliding groove 106, which allows the external assembly 6 to be slidably installed, realizing the effects of various detection methods of the equipment.

[0055] The connecting assembly 2 includes two connecting frames 201 and connecting posts 204. The connecting frames 201 are configured as a triangular structure, with reinforcing rods 205 on them. Two sets of connecting rods 203 are located at the ends of the connecting frames 201, with annular grooves 206 at the ends of the connecting rods 203. The connecting frames 201 are connected to the main frame assembly 1, thus forming a triangular structure that makes the connecting frames 201 more stable when fixed to the main frame assembly 1. The two sets of connecting rods 203 at the ends of the connecting frames 201 connect... The rod 203 is mainly a connecting fastener for the main connecting component 2 and the main frame assembly 1. Through the buffer at the end of the connecting rod 203, the end of the connecting rod 203 contacts the positioning component 3 for fixation. One section of the connecting frame 201 is connected to the vertical outer sleeve 202. The outer sleeve 202 is rotatably connected to the connecting column 204. The outer sleeve 202 is installed at the upper and lower ends of the connecting column 204. The connecting column 204 is provided with a shaft hole 207 and a boss 208. The connecting column 204 is hinged to the support component 4 through the shaft hole 207 to achieve the position fixation of the device.

[0056] The positioning component 3 includes a positioning block 301 and a first elastic element 302. The positioning block 301 has a block-shaped structure and is snapped into the second groove 107 on the main frame component 1, which is also the position for installing the connecting rod 203. A first slot 303 is provided in the positioning block 301 at the contact position with the connecting rod 203. The first elastic element 302 is provided on the positioning block 301. A protruding strip 304 is provided at the outer end of the positioning block 301. After the connecting rod 203 of the connecting component 2 is installed on the main frame component 1, the end of the connecting rod 203 will contact the first slot 303 and the end of the connecting rod 203 will directly snap into the first slot 303, so that the connecting component 2 is stably fixed on the main frame component 1. When disassembling the connecting component 2, the protruding strip 304 at the outer end of the positioning block 301 can be touched directly to slide the positioning block 301 outward, so that the first slot of the positioning block 301 is disengaged from the connecting rod 203, thereby achieving the disassembly of the connecting component 2.

[0057] The support assembly 4 includes a support frame 401 and a support rod 402. The support frame 401 has a frame-like structure and is hinged to the connecting column 204 through a shaft hole 207. The support rod 402 is connected to the outer end of the support frame 401, and a connector 405 is provided at the end of the support rod 402. A reinforcing sleeve 403 is slidably connected to the connector 405. The connector 405 allows different support rods 402 to be connected to each other. After connection, the reinforcing sleeve 403 can slide on the support rod 402, so that the reinforcing sleeve 403 is located at the connection point of the two support rods 402, thereby ensuring the connection stability of the support rod 402. The extended support rod 402 is designed to be able to rest against the wall at the other end, thus achieving a fixed effect on the entire device. A reinforcing sleeve 403 is fitted onto the support rod 402. Two sets of positioning plates 404 are slidably installed on the outer wall of the support frame 401. The positioning plates 404 are slidably connected to the connecting column 204 through the boss 208. The support frame 401 can swing on the connecting column 204, allowing the outer end of the support rod 402 to change its angle until it rests against the ground. The positioning plates 404 slidably installed on the outer end of the support frame 401 allow the positioning plates 404 to better contact the connecting column 204, thereby making the support assembly 4 more stable as a whole.

[0058] The fixing component 5 includes a swing block 501 and a fixing column 502. The swing block 501 is rotatably mounted on the main frame component 1. The main frame component 1 has a corresponding slot for installing the fixing component 5. The fixing column 502 is sleeved on the swing block 501. The bottom of the fixing column 502 is a ball head, and the top of the fixing column 502 is a corrugated head 503. A limiting platform 504 is provided on the fixing column 502. A second elastic element 505 is installed between the limiting platform 504 and the swing block 501. The fixing column 502 passes through the second elastic element 505. One end of the second elastic element 505 is connected to the limiting platform 504, and the other end of the second elastic element 505 is connected to the swing block 501. When the bearing component 7 of the rectangular opening 104 is installed, it slides onto the fixing plate 103. To ensure that the load-bearing component 7 can be stably fixed at the fixing plate 103, fixing components 5 are installed at the upper and lower ends of the main frame component 1, respectively. The swing block 501 can swing on the main frame component 1, which facilitates the pulling out of the fixing column 502. The fixing column 502 is used to fix the load-bearing component 7, which can realize the quick installation and disassembly of the load-bearing component 7. When it is necessary to fix the load-bearing component 7, simply hold the corrugated head 503 and pull the fixing column 502 outward. The fixing column 502 is then swung back to be horizontal with the main frame 101 by the swing block 501. At this time, the elastic force of the second elastic element 505 causes the fixing column 502 to extend into the main frame component 1, so that the fixing column 502 presses against the load-bearing component 7, thereby fixing the position of the load-bearing component 7 and increasing the stability of the load-bearing component 7 after installation.

[0059] The external assembly 6 includes an external plate 601 and a reinforcing plate 602. A slider 604 is provided on the external plate 601, and the external plate 601 is slidably mounted on the slide groove 106 via the slider 604. Bolts 605 are installed at the outer end of the external plate 601 at the contact position with the main frame assembly 1. The reinforcing plate 602 is provided on the outer surface of the external plate 601. A snap-fit ​​groove 603 is provided on one side of the external plate 601, and a protrusion 606 is provided on the inner wall of the snap-fit ​​groove 603. For testing of column-like structures in buildings, the external plate 601 is directly slidably mounted on the outer side of the side snap-fit ​​plate 102. After the outer plate 601 is installed, the bolts 605 are tightened to secure the outer plate 601 to the main frame assembly 1. The outer assembly 6 and the main frame assembly 1 form a clamping frame, allowing the outer assembly 6 to be clamped at both ends of the column to be tested. After the load-bearing component 7 is installed at the clamping groove 603, pressure is applied to the outer plate 601. The reinforcement plate 602 increases the stability of the outer plate 601. The protrusion 606 set at the clamping groove 603 allows the load-bearing component 7 to be installed at the clamping groove 603 for limiting, allowing the device to test the building column.

[0060] The supporting component 7 includes a supporting plate 701 with a mounting hole 703 in the middle. The testing device 8 and fastener 9 are connected to the supporting component 7 through the mounting hole 703. The outer wall of the supporting plate 701 has a second slot 704, which corresponds to the protrusion 606, to facilitate the mounting component 7 being snapped into the external component 6. The inner wall of the mounting hole 703 has a threaded or fixing groove 702. The fixing groove 702 has a concave-convex structure and corresponds to the snapping protrusion 801 on the outer wall of the testing device 8. The testing device 8 is connected to the supporting component 7 through the fixing groove 702. In order to allow the testing device 8 to be closer to the testing position, the testing device 8 is directly installed at the main frame component 1 and the external component 6 through the supporting component 7. The fastener 9 is threadedly connected to the supporting component 7 through the thread of the mounting hole 703, so that the fastener 9 can be adjusted on the supporting plate 701.

[0061] A method for using a device for testing the compressive strength of a building structure includes steps for testing the compressive strength of the walls and columns of a building.

[0062] The steps for testing the compressive strength of a wall are as follows:

[0063] A1: After determining the location of the wall to be tested, begin assembling the compressive strength testing device. The bearing component 7 is installed in the rectangular opening 104 and fixed by the fixing component 5. First, pull the corrugated head 503 at the top and bottom of the main frame component 1 outward to disengage the fixing column 502 from its original position. Swing the swing block 501 to swing the fixing column 502 to the outer end position. Insert the bearing component 7 into the rectangular opening 104 from any point at both ends of the fixing plate 103. Slide the bearing component 7 to slide it into the fixing plate 103. At this time, hold the corrugated head 503 and pull it outward to reset the fixing column 502 by swinging the swing block 501. The bottom of the fixing column 502 directly presses against the slots 704 at the top and bottom of the bearing component 7 to fix the bearing component 7. Install the testing device 8 on the bearing component 7. Install the snap-fit ​​protrusion 801 at the end of the testing device 8 into the fixing slot 702 of the bearing plate 701.

[0064] A2: Install the connecting bracket 201 on the main frame assembly 1. The connecting rod 203 extends directly into the main frame assembly 1. While installing the upper and lower sets of connecting brackets 201, connect the outer sleeve 202 to the connecting column 204, and make the connecting rod 203 snap into the positioning assembly 3. The connecting rod 203 can be directly snapped into the positioning assembly 3, realizing the quick installation of the connecting assembly 2.

[0065] A3: The connecting column 204 is hinged to the support frame 401 through the shaft hole 207, and the sliding positioning plate 404 is moved to the boss 208 to increase the stability of the contact between the support component 4 and the connecting component 2. When the support rod 402 needs to be lengthened, other support rods 402 are connected to the end of the support rod 402 through the connector 405, and then the reinforcing sleeve 403 is slid to the connection between the support rods 402 to make the reinforcing sleeve 403 stabilize the connection of the support rods 402.

[0066] A4: Place the end of the extended support rod 402 against another wall symmetrical to the wall being tested, or swing the hinged position of the support assembly 4 and the connecting column 204 downwards so that the end of the support rod 402 is fixed against the ground, forming a triangular frame structure. This achieves the fixation of the device at any height and position during testing, and the wall is tested by the testing equipment 8. This method is suitable for testing structures such as building beams, slabs and foundations with flat surfaces.

[0067] The steps for testing the compressive strength of a column are as follows:

[0068] B1: When testing the columns of a building, since the columns are set to be open on four or three sides, if the compressive strength testing device is already installed as in step A4, the connecting component 2 and the support component 4 need to be disassembled. First, slide the positioning component 3 at the main frame component 1 outward so that the positioning component 3 is no longer stuck to the end of the connecting rod 203, and then remove the connecting component 2 from the main frame component 1.

[0069] B2: Install the external plate 601 on the side plates 102 on both sides of the main frame 101, and then rotate the bolts 605 of the external plate 601 to fix the external plate 601 stably at both ends of the main frame assembly 1.

[0070] B3: Install the bearing assembly 7 at the snap-fit ​​groove 603 on both sides of the outer plate 601. Install the fastener 9 on one side of the bearing assembly 7 and install the testing device 8 on the other side of the bearing assembly 7. Move the main frame assembly 1 to the position on the column that needs to be tested, so that the pressure resistance testing device covers the column on three sides. Rotate the outer end of the fastener 9 until its inner end contacts the column, so that the device is fixed on the column and the test can begin. This setting allows the device to be used at any height on the column.

[0071] After the external component 6 is installed on the main frame assembly 1 of the same device, for smaller materials to be tested, the material can be placed directly between the two external components 6, so that the fastener 9 directly presses against the material, allowing the testing device 8 at the other end to perform the test, thus increasing the types of materials that the device can test.
