Description

Technical Field

[0001] This utility model relates to the technical field of testing equipment, and in particular to an auxiliary device for testing and installing the horizontal mechanical properties of a support. Background Technology

[0002] With the promulgation of seismic management regulations, the application of seismic isolation and damping products in building engineering is becoming increasingly widespread. Consequently, the testing of these products will become more standardized and rigorous. For example, during the testing of the horizontal mechanical performance of bearings... Figure 1 As shown, the sliding of the support is usually restricted by anti-slip top blocks and pressure blocks. However, when changing supports of different sizes, it is usually necessary to adjust the distance of the anti-slip top blocks. Therefore, for supports with large differences in size and model, it is often necessary to constantly adjust the position of the anti-slip top blocks. This not only affects the progress of the test, but also fails to ensure the uniformity of the force on the support, affecting the accuracy of the test results and increasing the danger of the test process. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the existing technology, an auxiliary device for testing and installing the horizontal mechanical properties of the support is provided. By adding a track-type steel plate to fill the gap between the small-sized support and the anti-slip top block, the anti-slip top block is avoided from moving significantly and the utilization rate of the anti-slip top block is improved.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an auxiliary device for testing and installing the horizontal mechanical properties of a support, used to help fill the gap between the support and the anti-slip top block. The device includes a track-type steel plate, sliding blocks, fixing blocks, and screws. The track-type steel plate is inserted into the gap between the support and the anti-slip top block. Two sliding blocks are horizontally slidably disposed on the track-type steel plate. Two fixing blocks are fixedly connected to an external fixing structure. A first nut is provided on the upper surface of the sliding block, and a second nut is provided on the upper surface of the fixing block. The screws are correspondingly inserted into the first nut and the second nut. By rotating the screws, the track-type steel plate can be finely adjusted in the horizontal direction.

[0005] To be further specific, in the above technical solution, the upper surface of the sliding block and the upper surface of the fixed block are located on the same horizontal plane.

[0006] To be further specific, in the above technical solution, the sliding block has a T-shaped structure, and the upper end of the sliding block is larger than the lower end of the sliding block.

[0007] To be further specific, in the above technical solution, the fixing block has a T-shaped structure, and the upper end of the fixing block is smaller than the lower end of the fixing block.

[0008] To be further specific, in the above technical solution, the groove pre-set on the fixing block cooperates with the T-shaped nut pre-set on the external fixing structure, and the groove uses the lateral constraint force of the T-shaped nut to achieve self-locking.

[0009] To be further specific, in the above technical solution, the specifications of the first nut are the same as those of the second nut.

[0010] To be further specific, in the above technical solution, the sliding block and the first nut are an integral structure, and the fixing block and the second nut are an integral structure.

[0011] The beneficial effects of this utility model are as follows: The auxiliary device for testing and installing the horizontal mechanical properties of a support according to this utility model has the following advantages:

[0012] 1. Fill the gaps by adding track-type steel plates to prevent significant movement of the anti-slip top blocks:

[0013] This application modifies the traditional horizontal test installation of bearings by adding an auxiliary device. By inserting a detachable rail-type steel plate in front of the anti-slip block of the large-sized bearing, the gap between the small-sized bearing and the anti-slip block is quickly filled, avoiding the tedious operation of repeatedly moving the anti-slip block in the traditional method. In addition, the rail-type steel plate increases the distance between the anti-slip block and the bearing, preventing the anti-slip block from colliding with the bearing during the ultimate shear deformation test.

[0014] 2. Rotatable screw connections may allow for quick installation and adjustment:

[0015] This application uses two threaded screws to form a rotatable connection with the fixed end. By rotating the screws, the horizontal fine adjustment and fixation of the track-type steel plate can be achieved, replacing the traditional bolt tightening method.

[0016] Third, the fixed end ensures the stability of the rail-type steel plate, making the test process more reliable:

[0017] The fixed end is connected to the groove by the T-nut pre-set on the test bench trolley plate. The groove's lateral constraint force is used to achieve self-locking. At the same time, the anti-slip top block presses the track-type steel plate in the horizontal direction. The double anti-slip mechanism ensures zero displacement of the track-type steel plate during the test, achieving effective force transmission.

[0018] IV. Expanded the scope of application of anti-slip top blocks:

[0019] This application expands the application scope of anti-slip top blocks, enabling their installation in horizontal mechanical performance testing of building seismic isolation bearings, bridge bearings, steel bearings, etc., greatly improving the utilization rate of anti-slip top blocks.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6This utility model discloses an auxiliary device for testing and installing the horizontal mechanical properties of a support, used to help fill the gap between the support 1 and the anti-slip top block 2. The device includes a track-type steel plate 3, sliding blocks 4, fixing blocks 5, and screws 6. The track-type steel plate 3 is inserted into the gap between the support 1 and the anti-slip top block 2. Two sliding blocks 4 are horizontally slidably arranged on the track-type steel plate 3. Two fixing blocks 5 are fixedly connected to an external fixing structure. A first nut 7 is provided on the upper surface of the sliding block 4, and a second nut 8 is provided on the upper surface of the fixing block 5. The screws 6 are correspondingly inserted into the first nut 7 and the second nut 8. By rotating the screws 6, the track-type steel plate 3 can be finely adjusted in the horizontal direction.

[0030] It should be noted that the scope of this application is not limited to rubber bearings; it can also be applied to some bridge bearings, steel bearings, etc. When bearing 1 is a rubber bearing, bearing 1 consists of an upper connecting plate, a lower connecting plate, and a rubber block, with the rubber block located between the upper and lower connecting plates. The upper connecting plate, lower connecting plate, and rubber block form a single test piece.

[0031] The upper surfaces of the sliding block 4 and the fixed block 5 are on the same horizontal plane. The sliding block 4 has a T-shaped structure, with its upper end larger than its lower end. The fixed block 5 has a T-shaped structure, with its upper end smaller than its lower end. A pre-set groove on the fixed block 5 engages with a pre-set T-nut on the external fixing structure, achieving self-locking through the lateral constraint of the groove on the T-nut. The specifications of the first nut 7 and the second nut 8 are the same. The sliding block 4 and the first nut 7 are integrally formed, as are the fixed block 5 and the second nut 8.

[0032] See Figure 6 The support 1 has a square structure. Two anti-slip blocks 2 are respectively set on two opposite sides of the support 1. The four anti-slip blocks 2 are distributed in a matrix. An auxiliary device is set between one side of the support 1 and the corresponding two anti-slip blocks 2. Another auxiliary device is set between the other side of the support 1 and the corresponding two anti-slip blocks 2.

[0033] This application adds a track-type steel plate 3, two sliding blocks 4, two fixing blocks 5, and two screws 6 to the existing support testing and installation. The sliding blocks 4 slide on the track-type steel plate 3, and their positions can be adjusted. The top of the sliding block 4 contains a first nut 7. The fixing blocks 5 can be connected to the groove of the test equipment trolley plate and move within the groove track. The top of the fixing blocks 5 contains a second nut 8. The sliding blocks 4 and fixing blocks 5 are connected by screws 6. The track-type steel plate 3 can transfer the horizontal force of the support 1 to the anti-slip top block 2, reducing the risk of the support 1 tilting or sliding due to uneven force distribution caused by the lower end of the anti-slip top block 2. The screws 6 are connected to the fixing blocks 5 to prevent the track-type steel plate 3 from popping out.

[0034] The auxiliary device for testing the horizontal mechanical performance of the bearing in this application has the following advantages: 1. By adding a track-type steel plate 3 to fill the gap, the large-scale movement of the anti-slip block 2 is avoided: This application modifies the traditional horizontal test installation of the bearing 1 by adding an auxiliary device. By inserting a detachable track-type steel plate 3 in front of the anti-slip block 2 of the large-size bearing 1, the gap between the small-size bearing 1 and the anti-slip block 2 is quickly filled, avoiding the tedious operation of repeatedly moving the anti-slip block 2 in the traditional method; in addition, the track-type steel plate 3 increases the distance between the anti-slip block 2 and the bearing 1, preventing the anti-slip block 2 from colliding with the bearing 1 during the ultimate shear deformation test; 2. The rotating connection screw 6 may allow for rapid installation and adjustment: This application uses two screws... The threaded screw 6 forms a rotatable connection with the fixed end. By rotating the screw 6, the horizontal adjustment and fixation of the track-type steel plate 3 can be achieved, replacing the traditional bolt tightening method. Third, the fixed end ensures the stability of the track-type steel plate 3, making the test process more reliable: the fixed end cooperates with the groove of the T-nut pre-set on the test bench trolley plate, and the lateral constraint force of the groove is used to achieve self-locking. At the same time, the anti-slip top block 2 presses the track-type steel plate 3 in the horizontal direction. The double anti-slip mechanism ensures zero displacement of the track-type steel plate 3 during the test, and achieves effective force transmission. Fourth, the application scope of the anti-slip top block 2 is expanded: this application expands the application scope of the anti-slip top block 2. It can be installed for horizontal mechanical performance testing of building seismic isolation bearings, bridge bearings, steel bearings, etc., which greatly improves the utilization rate of the anti-slip top block 2.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
