Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of impact test equipment, and more specifically, to an assembled partition wall impact test support rod. Background Art
[0002] With the rapid development of prefabricated buildings, prefabricated partition walls, as an important part of them, are receiving more and more attention for their performance testing, especially impact performance testing. Support rods specially used for prefabricated partition wall impact testing play a key supporting and auxiliary role in the impact testing process of prefabricated partition walls, and can ensure the accuracy and reliability of the test.
[0003] In the impact test of prefabricated partition walls, when the height of the supporting rod needs to be adjusted by telescopic sleeves, the positioning of the two inner and outer locating holes is not fast enough, which increases the operation steps. The operator needs to spend more time to align the locating holes. For example, the position of the sleeve may need to be repeatedly adjusted to ensure that the locating pin can be accurately inserted into the locating hole, thereby reducing the efficiency of test preparation. Utility Model Content
[0004] In response to the problems existing in the prior art, the purpose of the present utility model is to provide a support rod for an assembled partition wall impact test. This solution can flexibly adjust the height of the support rod to adapt to the test requirements of partition walls of different sizes, and the clamping inner plate can be moved relative to the lower slot under the fixed top plate to adjust the size of the clamping space, effectively improving the test efficiency and accuracy of the test. At the same time, the sliding process of the adjustment sleeve in the supporting outer column can be made more targeted, so that the corresponding positioning cross bar can pass through the four adjustment alignment holes more smoothly to fix it inside and outside, with higher docking accuracy and more convenient debugging.
[0005] In order to solve the above problems, the present invention adopts the following technical solutions.
[0006] The support rod for an impact test of an assembled partition wall comprises a support rod arranged on the assembled partition wall, the support rod comprises a support outer column, an adjustment sleeve is slidably connected to the lower side of the inner end of the support outer column, the upper end of the support rod is fixedly connected to a fixed top plate, the rear side of the lower end of the fixed top plate is fixedly connected to a rear side vertical plate, the lower end of the fixed top plate is provided with a lower slot, the front inner wall of the lower slot is fixedly connected to an elastic push rod, the rear end of the elastic push rod is fixedly connected to a clamping inner plate slidably connected in the lower slot, a plurality of adjustment alignment holes are provided at the left and right ends of the support rod and the adjustment sleeve, a positioning cross bar is passed through the plurality of horizontally corresponding adjustment alignment holes, a silicone outer ring is fixedly connected to the outer side of the adjustment alignment hole in the adjustment sleeve, and a protruding head is fixedly connected to the outer side of the silicone outer ring.
[0007] Furthermore, a plurality of corresponding adjustment and alignment holes are equidistantly distributed from top to bottom, and the rear vertical plate of the protruding head and the clamping inner plate are respectively engaged with the front and rear sides of the assembled partition wall.
[0008] Furthermore, the ends of the rear vertical plate and the clamping inner plate that are close to each other are fixedly connected with a wear-resistant inner layer, and the wear-resistant inner layer is in contact with the front and rear outer walls of the assembled partition wall.
[0009] Furthermore, anti-pullout grooves are symmetrically provided on the upper and lower inner walls of the adjustment alignment hole in the adjustment sleeve.
[0010] Furthermore, the upper and lower ends of the positioning crossbar are symmetrically fixedly connected with electric push rods, and the output ends of the electric push rods are fixedly connected with engaging blocks.
[0011] Furthermore, the engaging blocks are engaged with the corresponding anti-pullout slots, and the upper inner wall of the supporting outer column is fixedly connected with a telescopic sleeve rod.
[0012] Furthermore, the lower end of the telescopic sleeve is connected to the upper end of the adjusting sleeve, and the lower end of the adjusting sleeve is provided with an impact ball.
[0013] Compared with the prior art, the advantages of the present invention are:
[0014] (1) This solution can flexibly adjust the height of the support rod to meet the test requirements of partition walls of different sizes, and the clamping inner plate can be moved relative to the lower slot below the fixed top plate to adjust the size of the clamping space, effectively improving the test efficiency and accuracy. At the same time, the adjustment sleeve can be pushed up and down in the support outer column by hand, and the protruding heads outside the silicone outer ring on both sides of the adjustment sleeve can form a special damping force when pushing. When the protruding heads are docked with the corresponding adjustment alignment holes, the operator can clearly feel a similar damping change, which can make the sliding process of the adjustment sleeve in the support outer column more targeted, and make the corresponding positioning cross bar pass through the four adjustment alignment holes more smoothly to fix them, with higher docking accuracy and more convenient debugging.
[0015] (2) At the same time, when the positioning cross bar is inserted into the corresponding adjustment alignment hole, anti-pullout grooves can be set on the upper and lower sides of the internal adjustment alignment hole. After the positioning cross bar is in place, the anti-pullout grooves can use an external controller to push the two electric push rods outward so that the locking blocks are locked into the anti-pullout grooves, making it less likely for the positioning cross bar to fall due to the impact test, thereby making the overall locking force of the support rod tighter.

The lower end of the fixed top plate 6 is provided with a lower slot 9, and the front inner wall of the lower slot 9 is fixedly connected with an elastic push rod 10. The rear end of the elastic push rod 10 is fixedly connected with a clamping inner plate 8 which is slidably connected in the lower slot 9. The left and right ends of the support rod 1 and the adjusting sleeve 3 are provided with a plurality of adjusting alignment holes 4, and a positioning cross bar 5 is passed through the plurality of adjusting alignment holes 4 corresponding to the horizontal level. The outer side of the adjusting alignment hole 4 in the adjusting sleeve 3 is fixedly connected with a silicone outer ring 12, and the outer side of the silicone outer ring 12 is fixedly connected with a protruding head 13.
[0027] See also Figure 1-4 , multiple corresponding adjustment alignment holes 4 are equidistantly distributed from top to bottom, the rear side vertical plate 7 of the protruding head 13 and the clamping inner plate 8 are respectively engaged in the front and rear positions of the prefabricated partition wall, and the ends of the rear side vertical plate 7 and the clamping inner plate 8 close to each other are fixedly connected with a wear-resistant inner layer 11, and the wear-resistant inner layer 11 is in contact with the front and rear outer walls of the prefabricated partition wall. The upper and lower inner walls of the adjustment alignment hole 4 in the adjustment sleeve 3 are symmetrically provided with anti-pullout grooves 16, and the upper and lower ends of the positioning cross bar 5 are symmetrically fixed with electric push rods 15, and the output end of the electric push rod 15 is fixedly connected with a locking block 17, which is engaged with the corresponding anti-pullout grooves 16.
