Description

Technical Field

[0001] This utility model relates to the field of building material load-bearing capacity testing technology, specifically a load-bearing capacity testing device for building safety testing. Background Technology

[0002] Buildings are places where people live, work, and play. Safety testing of building materials can promptly detect structural defects, fire hazards, and other problems, preventing building collapses, fires, and other accidents that threaten human lives. Staircases, ramps, or open areas of buildings often have many supporting structures. The load-bearing capacity of these supporting materials directly affects construction safety. Generally, load-bearing capacity testing devices are used to test these supporting materials. Because columnar materials have small cross-sections, manual support is required during testing. The columnar material is placed vertically on the platform of the load-bearing capacity testing device. The testing head is pressed down, supporting the top of the columnar object, and then the hands are released while the load-bearing capacity testing device continuously applies pressure to test the load-bearing capacity of the object. However, during the support process, if the testing head is pressed down too quickly or the hands are released too late, there is a risk of hand injury. Furthermore, manual support can easily cause the columnar object to tilt or shift, affecting the test parameters. Therefore, a load-bearing capacity testing device for building safety testing is provided. Utility Model Content

[0024] Please see Figure 1-4This utility model provides an embodiment of a load-bearing capacity testing device for building safety testing, comprising a body 1, a platform 11 at the bottom of the body 1, an anti-slip plate 12 at the top of the platform 11, a cylinder 5 at the top of the body 1, a pressure plate 4 at the bottom of the cylinder 5, four sets of guide columns 6 penetrating the interior of the pressure plate 4, a pressing component 7 at the center of the bottom of the pressure plate 4, a pressure sensor at the bottom of the pressing component 7, side plates 3 on both sides of the center of the body 1, a lead screw 15 and a guide rod 17 between the side plates 3, a drive motor 8 at one end of the lead screw 15, a sliding block 9 on the outer side of the lead screw 15 and the guide rod 17, and a clamping plate 10 at the front end of the sliding block 9. The bottom end of the sliding block 9 is provided with a linear slide rail assembly 2. The lead screw 15 and the guide rod 17 are parallel to each other. The threads on the outer side wall of the lead screw 15 are centrally symmetrically distributed. There are two sets of sliding blocks 9 and clamping plates 10. The sliding blocks 9 and clamping plates 10 are centrally symmetrically distributed on both sides of the lead screw 15. The sliding block 9 has a threaded groove that mates with the lead screw 15. The sliding block 9 also has a through groove that mates with the guide rod 17. A rubber pad 16 is installed on one side of the clamping plate 10. The bottom end of the linear slide rail assembly 2 is provided with a boss. The boss and the machine body 1 form an integrated structure. The cooperation between the linear slide rail assembly 2 and the guide rod 17 has a limiting and guiding effect on the movement of the sliding block 9, so that the sliding block 9 can slide smoothly.

[0025] Specifically, as shown in the figure, during use, the operation of the drive motor 8 will drive the lead screw 15 to rotate, which, in conjunction with the threaded connection with the sliding block 9, controls the sliding block 9 to slide on the linear slide rail assembly 2 and the guide rod 17. The two sets of sliding blocks 9 will move together or away, and with the setting of the rubber pad 16, the two sets of clamping plates 10 will drive the columnar object to be centered and clamped.

[0026] The top of the sliding block 9 and the clamping plate 10 are equipped with a support plate 14, and the support plate 14 and the pressure plate 4 are parallel to each other. The two sets of support plates 14 can support the two sides of the bottom of the plate-shaped object. The movement of the sliding block 9 and the clamping plate 10 together or apart can adjust the appropriate spacing according to the size of the plate-shaped object.

[0027] The bottom end of the pressing component 7 is equipped with a detection head 13. Two sets of fixing bolts 19 are installed inside the detection head 13, and the fixing bolts 19 and the pressing component 7 are connected by threads. The detection head 13 is provided with a mating groove 18, and the size of the mating groove 18 is adapted to the size of the pressing component 7.

[0028] Specifically, as shown in the figure, during use, the mating groove 18 is set at the center position inside the detection head 13, and the size of the mating groove 18 is adapted to the size of the pressing component 7, so that the detection head 13 can be mated to the bottom end of the pressing component 7. With the distribution of two sets of fixing bolts 19, the position of the detection head 13 can be fixed.

[0029] Working principle: In use, firstly, the load-bearing capacity testing device is moved to the target area, and the building material to be tested is retrieved. If it is a columnar object, the columnar object is placed vertically at the bottom of the testing head 13, and the drive motor 8 is operated to drive the lead screw 15 to rotate. This, combined with the threaded connection with the sliding block 9, controls the sliding block 9 to slide on the linear guide rail assembly 2 and the guide rod 17. The two sets of sliding blocks 9 move together, and with the rubber pad 16 in place, the two sets of clamping plates 10 clamp and position the columnar object in the center. Subsequently, the cylinder 5 is operated to push the pressure plate 4 downwards, controlling... The detection head 13 contacts the top of the cylindrical object, and then the drive motor 8 is controlled to operate, controlling the two sets of sliding blocks 9 to move away and release the clamping of the cylindrical object. Next, the cylinder 5 is controlled to operate, pushing the pressure plate 4 downward, and controlling the detection head 13 to squeeze the cylindrical object downward to detect the load-bearing capacity of the cylindrical object. When testing a plate-shaped object, the plate-shaped object is placed flat on top of the two sets of support plates 14, and the cylinder 5 is controlled to operate, pushing the pressure plate 4 downward, and controlling the detection head 13 to squeeze the plate-shaped object downward to detect the load-bearing capacity of the plate-shaped object. Finally, the use of the load-bearing capacity testing device is completed.
