Description

Technical Field

[0001] This utility model relates to the field of building impact resistance testing, and in particular to an impact testing device for prefabricated partition walls. Background Technology

[0002] In prefabricated concrete buildings, prefabricated lightweight wall panels are often used as interior partitions to divide the building's interior space into multiple unit spaces. Prefabricated lightweight wall panels are non-load-bearing components, and their connection to adjacent concrete structures is relatively simple, using mortar bonding. However, they may be subject to impacts during actual use. To ensure personnel safety, impact tests are necessary to simulate and test their impact resistance under impact. Patent document CN213689235U provides a device for testing the impact resistance of prefabricated interior partitions in prefabricated buildings. This device includes a mounting ring 8. Before determining the impact point of the wall panel to be tested, the testing personnel fix the mounting ring 8 to the ceiling above the impact point. Then, an impactor 4, with a suspension rope 2 suspended from the top, is suspended from the mounting ring 8, aligning the vertically positioned impactor 4 with the impact point. The testing personnel pull the impactor 4 suspended on the mounting ring 8 forward and upward to a certain height, then release the impactor 4, allowing it to swing forward and impact the impact point on the prefabricated wall panel 1. This process is repeated multiple times. Then, by reading the deformation value of the wall panel measured by the displacement gauge 10 pre-installed on the back of the prefabricated partition wall, the impact resistance performance of the wall panel can be evaluated. However, using this testing device to conduct impact tests on the prefabricated wall panel requires pre-installing a fixing ring on the ceiling in front of the top of the prefabricated wall panel, which is cumbersome. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a prefabricated partition wall impact testing device that can perform prefabricated partition wall impact tests without the need to install a fixed mounting ring as the suspension point for the swing impact of the impactor, and is easy to operate.

[0004] To solve the above problems, the present invention provides a prefabricated partition wall impact testing device, which includes a telescopic support on the ground and an impact body suspended on its top.

[0005] Furthermore, the retractable support includes a base and a column rotatably mounted on the base, with the impactor suspended on top of the column; the column can be rotated downwards to retract into alignment with the base.

[0006] Furthermore, a suspension bracket extends forward and upward from the top of the column, and the impact body is suspended at the end of the suspension bracket. The suspension bracket can be rotated downward and retracted to be flush with the column.

[0007] Furthermore, a drive wheel is rotatably mounted on the telescopic support, and a suspension rope is wound around the drive wheel. The impact body is suspended from the top of the telescopic support via the suspension rope. The rotation of the drive wheel retracts and releases the suspension rope, causing the impact body to rise and fall vertically.

[0008] Furthermore, the telescopic bracket is equipped with a handle, which includes an output shaft. A drive wheel is mounted and fixed on the output shaft. When the handle is turned, the output shaft rotates, causing the drive wheel to rotate.

[0009] Furthermore, the output shaft of the handle is provided with a first retaining ring, and the telescopic bracket is provided with a second retaining ring. The first retaining ring moves along the output shaft and approaches the second retaining ring until the first retaining ring engages with the second retaining ring and locks the drive wheel to a stop.

[0010] Furthermore, a guide wheel is installed at the top of the column, and a lifting ring is installed on the right side of the column; a strip-shaped through hole is opened at the beginning of the suspension frame; a pull rope is installed on the side of the impact body, and its end passes through the strip-shaped through hole, the guide wheel, and the lifting ring in sequence before hanging down for manual pulling.

[0011] Furthermore, the columns are retractable.

[0012] Furthermore, the retractable bracket is equipped with casters at the bottom.

[0013] Beneficial Effects: The testing personnel support the telescopic bracket on the ground in front of the prefabricated wall panel. Adjusting the telescopic bracket raises it until its top is above the impact point on the wall panel. The impactor, suspended at the top of the bracket, is then pulled upwards and backwards to the desired height. The impactor is then released, allowing it to swing forward from the top of the telescopic bracket as its suspension point to impact the impact point on the prefabricated wall panel in front of it. Using this testing device for prefabricated partition wall impact testing eliminates the need for additional fixed mounting rings as the suspension point for the impactor's swing, making operation convenient. This testing device effectively solves the problem of inconvenient or unavailable on-site installation of fixed mounting rings, improving work efficiency and ensuring the safety of the testing personnel.

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to specific embodiments.

[0022] Prefabricated partition wall impact testing device, such as Figure 1 As shown, the device includes a column 12 rotatably mounted on a base 11, with a suspension bracket 13 extending forward and upward from the top of the column 12. The base 11, column 12, and suspension bracket 13 together form a telescopic support 1 for suspending the impactor 2. Two mounting protrusions 18 extend rearward from the upper left and right sides of the column 12, with a drive wheel 14 rotatably mounted between the two mounting protrusions 18. A handle 17 is mounted on the right side of the right mounting protrusion 18, and its output shaft 171 (see...) Figure 4 The drive wheel 14 is rotatably inserted into two mounting protrusions 18 facing left. It is fixed to the output shaft 171 of the handle 17. When the handle 17 is rotated, the output shaft 171 rotates, driving the drive wheel 14 to rotate. A guide wheel 15 is provided on the rear side of the top of the column 12, and a suspension wheel 16 is provided at the end of the suspension frame 13. A suspension rope 3 is wound on the drive wheel 14. The suspension rope 3 passes through the guide wheel 15 and the suspension wheel 16 in sequence and then hangs vertically downwards. The impact body 2 is installed and suspended at the bottom. When the inspector rotates the handle 17, it drives the drive wheel 14 to rotate, which in turn winds up and unwinds the suspension rope 3, causing the impact body 2 to rise and fall vertically.

[0023] See Figure 2After the testing personnel determine the impact point of the wall panel 5 to be tested, they place the upright 7, equipped with a magnetic base 71, on the ground behind the back of the wall panel 5. A displacement gauge 6 is mounted on the magnetic base 71, facing forward and contacting the back of the wall panel 5. The testing device is then placed on the ground in front of the front of the wall panel 5. Using the rollers 19 at the bottom of the base 11, the entire testing device is moved forward to align with the impact point, and then the rollers 19 are locked. The upright 12 is telescopic; adjusting it raises the suspension wheel 16 to the required height (at least 0.45m above the impact point). Then, the handle 17 is turned to release the suspension rope 3, causing the impactor 2 to descend vertically to align with the impact point on the wall panel 5. See [link / description]. Figure 4 and Figure 5 The output shaft 171 of the handle 17 is provided with a first retaining ring 172, which has a retaining block 173 protruding radially inward. The retaining block 173 is slidably installed in a retaining groove 174 opened along the axial direction of the output shaft 171. A second retaining ring 181 is provided on the right side of the right mounting protrusion 18. When the inspector pushes the first retaining ring 172 to the left so that it is close to the second retaining ring 181, the retaining block 173 moves to the left along the groove 174 until the first retaining ring 172 engages with the second retaining tooth 1811 to achieve locking, thereby locking the drive wheel 14 to stop, and the suspension rope 3 will stop releasing the line.

[0024] See Figure 1 A lifting ring 182 is installed on the right side of the protrusion 18. A strip-shaped through hole 131 is opened at the beginning of the suspension bracket 13. A pull rope 4 is installed on the side of the impactor 2. The end of the pull rope 4 passes through the strip-shaped through hole 131 to the rear and then passes down through the lifting ring 182 via the guide wheel 15. The testing personnel hold the end of the pull rope 4 and pull it downwards, moving the impactor 2 to a height of 0.45m above the impact point (as required by the partition wall impact test operation specifications). Then, the pull rope 4 is released to release the impactor 2, allowing it to swing forward and impact the impact point on the partition wall 5 to be tested. After the impactor 2 impacts the impact point, the testing personnel can promptly pull the pull rope 4 to prevent a secondary impact. This completes the first impact test on the wall panel 5 to be tested. The testing personnel repeat the previous steps, impacting the wall panel 5 five times to complete the impact test. The deformation value of the wall panel 5 is measured by the displacement gauge 6 on the back of the wall panel 5. The condition of the wall panel 5 surface and its connection with adjacent wall panels are observed to evaluate its impact resistance. After the impact test of the wall panel 5 is completed, the testing personnel can operate the suspension bracket 13 to rotate downwards and retract it until it is flush with the column 12, and then rotate it downwards and retract the column 12 until it is flush with the base 11. Figure 3As shown, it is easy to store. Furthermore, the two forward-facing legs on the base 11 can rotate relative to each other to fold together. A mounting base 72 is detachably installed at the bottom of the upright 7, and the upright 7 stands stably behind the back of the wall panel 5 to be tested via the mounting base 72. The upright 7, mounting base 72, magnetic base 71, and displacement meter 6 together form a displacement measuring device to measure the displacement of the wall panel 5 to be tested after it has been impacted.

[0025] The impactor 2 can be a sandbag, steel ball, or counterweight with an air cushion on its surface, etc., which the testing personnel can choose according to the test requirements. In addition to conducting impact tests on prefabricated partition walls, this testing device can also be used to conduct impact tests on railings against soft heavy objects.

[0026] The above description is merely an embodiment of the present invention and does not limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on the present invention will still fall within the scope of patent protection.
