Description

Technical Field

[0001] This utility model belongs to the technical field of building material testing equipment, specifically relating to a device for testing the crack resistance and bearing capacity of precast concrete cover plates. Background Technology

[0002] Precast concrete slabs are widely used in construction engineering. To ensure their quality and safety, it is necessary to test the crack resistance of precast concrete slabs. Traditional testing devices often have limitations in adjusting the testing position, making it difficult to flexibly adjust the position of the pressure testing components according to different sizes and testing requirements, resulting in low testing efficiency and affecting the accuracy of the test results. Utility Model Content

[0003] To address the problems mentioned in the background section, this invention provides a device for testing the crack resistance bearing capacity of precast concrete slabs. This device allows for convenient and quick adjustment of the bearing capacity testing position, improving testing efficiency and accuracy.

[0004] This utility model discloses a precast concrete cover plate crack resistance bearing capacity testing device, including a support and a cover plate bracket mounted on the support. A pressure testing component is mounted on the support via a front-to-back adjustment mechanism.

[0005] The front-to-back adjustment mechanism includes a T-shaped guide groove on the support. A guide block, shaped to fit the groove, is housed inside the guide groove and slidably connected to the support via the groove. A lead screw is installed inside the guide groove, with one end movably mounted on the support via a bearing, and the other end passing through the support and fitted with a rotating handle. The rotating handle has an anti-slip sleeve with anti-slip texture. A threaded hole is located at the center of the guide block, and the lead screw is screwed into this hole. Rotating the rotating handle rotates the lead screw, causing the guide block to move back and forth within the guide groove, thus adjusting the front-to-back position of the pressure detection assembly.

[0006] The pressure detection assembly includes a pressing mechanism fixed to guide block one, and a data detection mechanism fixed to the pressing mechanism. The pressing mechanism includes a support column fixed to guide block one, a mounting plate mounted on the support column, and a pair of guide rails mounted on the mounting plate. The guide rails are fixedly connected to the mounting plate by welding. Guide block two is mounted on the guide rails, and a mounting seat for mounting the data detection mechanism is fixedly installed between the two guide blocks two. The guide blocks and the mounting seat are manufactured using an integrated molding process. A cylinder is mounted on the top of the mounting plate, and one end of the cylinder's piston rod is fixedly connected to the mounting seat. By extending and retracting the cylinder piston rod, the vertical position of the data detection mechanism can be adjusted, further enabling adjustment of the detection position for precast concrete slabs of different heights.

[0007] Compared with the prior art, the beneficial effects of this utility model are:

[0008] Based on the dimensions of the precast concrete cover plate, the front and rear positions of the pressure detection component can be adjusted by rotating the handle, so that the data detection mechanism is aligned with the position of the precast concrete cover plate to be tested. The front and rear positions of the pressure detection component can be easily adjusted to meet the testing needs of precast concrete cover plates of different sizes and improve testing efficiency.
