Description

Technical Field

[0001] The utility model relates to the technical field of tensile testing, in particular to a raw material tensile testing device for construction engineering. Background Technique

[0002] At present, during building construction, in order to ensure the safety of the building, before construction, it is necessary to conduct a tensile test on building materials to ensure the quality of the project construction. Tensile testing is to slowly pull a material specimen under the action of an axial force until it breaks, mainly to measure the yield strength, tensile strength, and elongation of materials such as low-carbon steel.

[0003] The existing patent document with the publication number CN217111835U discloses a tensile testing device for construction engineering inspection, including a bottom plate. A bracket is fixedly installed on the top side of the bottom plate, and a hydraulic cylinder is fixedly installed at the top of the bracket. Two aligned mounting plates are fixedly installed on the output end of the hydraulic cylinder and the top side of the bottom plate respectively. A protective mechanism fixed to the side of the bracket is arranged between the two mounting plates.

[0004] However, the above device has the following problems when in use;

[0005] (1) First, since the protective mechanism is fixedly installed on the bracket and the protective mechanism is closed and cannot be opened, this leads to limited space when placing long and thin objects to be tested, which is rather inconvenient.

[0006] (2) Second, after the debris generated by fragmentation collides with the rubber cylinder inside the protective mechanism, there is no treatment. Instead, the debris will directly fall into the inside of the annular block under the action of gravity. It is necessary to clean it in time after each use, otherwise it will affect the normal progress of subsequent clamping activities.

[0007] Therefore, we propose a raw material tensile testing device for construction engineering to solve the above problems. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0028] Please refer to Figures 1 to 5 , a raw material tensile testing device for construction engineering, including a body 1, on which a fixing frame 2 and a clamping assembly 3 are provided. The number of the clamping assemblies 3 is two, and the two clamping assemblies 3 are arranged in a straight line. The distance between the clamping assemblies 3 can be specifically changed according to the length of the object to be tested.

[0029] Two fixing rings 5 are slidably installed inside the fixing frame 2, and a bellows cover 4 is fixedly installed between the two fixing rings 5;

[0030] Both of the two fixing rings 5 can slide on the fixing frame 2, and thus the distance between the two fixing rings 5 can also be adjusted. The length of the bellows cover 4 stretches synchronously with the distance between the two fixing rings 5, enabling targeted adjustment according to different needs and ensuring that it does not affect the normal feeding process.

[0031] Clamping devices 6 are arranged on both sides of the two fixing rings 5;

[0032] Two fixing bars 20 are fixedly installed on the fixing frame 2, and limiting grooves 21 are evenly and equidistantly formed on the fixing bars 20. The limiting grooves 21 are adapted to the clamping devices 6;

[0033] By engaging the clamping devices 6 with the limiting grooves 21 at different positions, the fixing rings 5 can be at different heights, and thus the distance between the two fixing rings 5 is changed.

[0034] A connecting cylinder 7 is fixedly installed on the fixing ring 5 at the bottom. A bottom plate 8 is movably installed on the connecting cylinder 7, and a slag receiving plate 12 and a rubber block 13 are fixedly installed on the bottom plate 8.

[0035] When the object breaks and generates debris, the debris splashes. Some of the debris first contacts the inner surface of the bellows cover 4. The folding gaps between the bellows covers 4 can accommodate some of the debris, and the remaining debris directly falls onto the slag receiving plate 12 and the rubber block 13 under the action of gravity.

[0036] After the test is completed, the bellows cover 4 should be in a fully expanded state and be patted, so that the debris inside the gaps of the bellows cover 4 will also fall onto the surfaces of the slag receiving plate 12 and the rubber block 13 under the action of gravity, facilitating later removal and cleaning.

[0037] An internal thread groove 10 is formed on the connecting cylinder 7. A fixing cylinder 9 is fixedly installed on the bottom plate 8, and an external thread 11 is formed on the fixing cylinder 9. The internal thread groove 10 and the external thread 11 are in threaded cooperation.

[0038] Through the cooperation of the internal thread groove 10 and the external thread 11, the installation and disassembly of the bottom plate 8 can be carried out conveniently and quickly, and thus the debris can be cleaned in time.

[0039] The upper part of the slag receiving plate 12 is frustum-shaped, the lower part of the slag receiving plate 12 is circular-ring-shaped, and the edge of the slag receiving plate 12 is blocked by the fixing cylinder 9.

[0040] Since the upper part of the slag receiving plate 12 is frustum-shaped, the debris will move towards the edge of the frustum shape, and there is a fixed cylinder 9, so most of the debris is on the surface of the slag receiving plate 12.

[0041] The rubber block 13 is made of elastic material, and a placement hole 14 is provided at the center of the rubber block 13.

[0042] The steel bar to be tested passes through the placement hole 14. Under the action of the two clamping assemblies 3, tensile testing is carried out. The elasticity of the rubber block 13 enables it to be applicable to steel bar detection activities of different diameters.

[0043] The positioning device 6 includes a mounting block 15. The mounting block 15 is fixedly installed on the fixed ring 5. A spring 16 is fixedly installed on the mounting block 15. The other end of the spring 16 is fixedly installed with a moving block 17. A limiting rod 19 is fixedly installed on the moving block 17. The limiting rod 19 passes through the mounting block 15. A pulling block 18 is also fixedly installed on the pulling block 18. A sliding groove for the pulling block 18 to slide is provided on the mounting block 15.

[0044] By moving the pulling block 18 towards the spring 16, the spring 16 is compressed. The moving block 17 and the limiting rod 19 thereon move towards the spring 16 synchronously. Then the limiting rod 19 moves out of the limiting groove 21, so that the fixed ring 5 can move in the vertical direction.

[0045] A sliding block 22 is slidably installed on the fixed strip 20. The sliding block 22 can accommodate the limiting rod 19. No matter how far the limiting rod 19 moves, a part of the limiting rod 19 is always inside the sliding block 22.

[0046] When the limiting rod 19 moves out of the limiting groove 21, the limiting rod 19 will be inside the sliding block 22. Then the sliding block 22 can limit its movement trajectory to ensure that it can only move in the vertical direction.

[0047] The working process of the present utility model: First, place the steel bar so that the distance between the two fixed rings 5 is the smallest, and make the two fixed rings 5 in the position that least affects the placement of the steel bar. Then make the steel bar pass through the placement hole 14 at the center of the rubber block 13, and both ends of the steel bar are clamped by the clamping assemblies 3.

[0048] After that, adjust the length between the two fixed rings 5 according to actual needs. By making the two pulling blocks 18 approach each other, that is, the pulling block 18 moves towards the spring 16, the spring 16 is compressed. The moving block 17 and the limiting rod 19 thereon move towards the spring 16 synchronously. Then the limiting rod 19 moves out of the limiting groove 21, so that the fixed ring 5 can move in the vertical direction.

[0049] After the fixed ring 5 is moved to the required position, the force applied to the pulling block 18 is cancelled, so that the limiting rod 19 can return to the limiting groove 21 at the corresponding height again. Then the two fixed rings 5 are in a stable placement state, and the length of the bellows 4 is stretched synchronously with the distance between the two fixed rings 5.

[0050] After that, the tensile test of the steel bar is carried out. When the steel bar breaks, debris splashes. Some debris first contacts the inner surface of the bellows 4. The folding gaps between the bellows 4 can accommodate part of the debris, and the remaining debris will directly fall onto the slag receiving plate 12 and the rubber block 13 under the action of gravity.

[0051] When the test is completed, the bellows 4 is in a fully unfolded state and is patted, so that the debris inside the gaps of the bellows 4 will also fall onto the surfaces of the slag receiving plate 12 and the rubber block 13 under the action of gravity, and all the debris will be concentrated on the surface of the slag receiving plate 12.

[0052] After that, through the cooperation of the internal thread groove 10 and the external thread 11, the bottom plate 8 can be disassembled conveniently and quickly. At this time, the steel bar is inserted into the placement hole 14 at the center of the rubber block 13, so the debris will not fall through the placement hole 14, and the debris can be completely inside the closed space.

[0053] Remove the bottom plate 8 and clean the slag receiving plate 12 and the rubber block 13.

[0054] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
