Technical Field
[0001] This utility model belongs to the field of highway bridge technology, and in particular relates to a strength testing instrument for highway bridge construction. Background Technology
[0002] The functions of highway bridges are as follows: connecting rivers, valleys, and highways on both sides, allowing vehicles and pedestrians to pass smoothly over obstacles such as rivers and valleys, thereby shortening travel time and distance and improving traffic efficiency; concrete blocks are the material used to build highway bridges, and the concrete blocks used in highway bridge construction need to be tested for strength so that staff can determine whether the strength of the constructed highway bridge meets the construction standards, thereby increasing the safety of the highway bridge during use.
[0003] A search revealed a patent document with publication number CN220568572U disclosing a strength testing instrument for highway bridge construction, comprising: a protective cover and a collection plate. The collection plate is installed on the rear end face of the protective cover, and a collection groove is formed on the upper surface of the collection plate. The protective cover is installed between two sets of support frames, and a disassembly assembly is installed between the protective cover and the collection plate. The disassembly assembly includes a mounting base and an insert block. An observation window is installed on the inner wall of the protective cover, and the observation window is made of tempered glass. Through multiple sets of collection plates following the closing of the protective cover, it can surround the perimeter of the support frame. Concrete fragments scattered during the testing process can be collected by the collection groove, and the concrete fragments can be cleaned by simply dumping them, resulting in high cleaning efficiency. Through the observation window, the strength that the concrete can withstand can be seen directly. Moreover, the observation window is made of fiberglass, which is not easily damaged by the splashing of concrete fragments.
[0004] The aforementioned strength testing instrument for highway bridge construction has a testing frame supported by four sets of support frames. A hydraulic cylinder is installed on the top of the testing frame, and a top plate is installed at the output end of the hydraulic cylinder. A support seat with a corresponding position is installed on the inner surface of the testing frame. The protective cover is installed with the support frame via hinges. A handle is fixedly installed on the front end of the protective cover, and an observation window is installed on the inner wall of the protective cover. However, the protective cover cannot completely block the gap between two adjacent support frames. Consequently, during the strength testing of concrete blocks used in highway bridge construction, fragments of concrete blocks may fly out and accidentally injure workers, reducing safety. Furthermore, it includes a protective cover and a collection plate. The collection plate is installed on the rear end of the protective cover, and a collection groove is opened on the upper surface of the collection plate. Two sets of support frames... Protective covers are installed between the frames, and a disassembly assembly is installed between the protective covers and the collection plates. The disassembly assembly includes a mounting base and an insert. The side wall of the collection plate is provided with an adaptation groove, the shape of which is adapted to the support base, and the position of the collection plate is at the same level as the support base. Both side walls of the collection plate are provided with a 45-degree bevel. Four sets of collection plates are fitted around the support base. The mounting base is fixed to the inner wall of the collection groove. The front end face of the mounting base has an installation groove. The insert is engaged with the installation groove. The insert is made of magnetic material, and a magnetic plate is installed on the inner wall of the installation groove. The insert and the magnetic plate attract each other. However, workers need to disassemble and assemble multiple sets of collection plates, which increases the number of steps required for workers to clean up concrete debris from highway bridge construction, thus increasing the workload of workers.
[0005] To address these issues, we have provided a strength testing instrument for highway bridge construction. Utility Model Content

By controlling the hydraulic cylinder 104, the height of the stamping plate 105 is adjusted, thereby applying pressure to the concrete blocks used for highway bridge construction, so as to realize the strength testing of the concrete blocks used for highway bridge construction.
[0031] Specifically, a connecting plate 102 is provided above the testing box 1. A support leg 102a is connected to the lower surface of the connecting plate 102, and the lower surface of the support leg 102a is connected to the upper surface of the testing box 1.

[0034] Example 2
[0035] Please see Figure 1 , Figure 2 and Figure 3, on the basis of the first specific embodiment, a plugging component 2 is provided. The plugging component 2 includes a door frame 201, a toughened glass plate 201a, a plug 201b, a sliding rod 201c, a strip plate 202, an ear plate 203, a bolt 203b, a nut 203c, a screw rod 203d and a bearing 203e. An external force is applied to the ear plate 203 to adjust the height of the door frame 201, thereby unlocking the opening side of the test box 1, facilitating the staff to take and place the concrete blocks for highway bridge construction inside the test box 1. When the plugging component 2 shields the opening side of the test box 1, it effectively prevents the concrete blocks for highway bridge construction from splashing and injuring the staff during the strength test, improving the safety during the strength test of the concrete blocks for highway bridge construction;

An upward external force is applied to the ear plate 203, the slide rod 201c moves upward along the slide groove 106, the door frame 201 moves upward, and the tempered glass plate 201a moves upward until the ear plate 203 moves above the connecting plate 102. The operator rotates the ear plate 203 to move it to the initial position, and tightens the bolt 203b counterclockwise so that the lower end of the bolt 203b is threaded to the upper surface of the connecting plate 102, limiting the height of the door frame 201 and removing the obstruction of the opening side of the detection box 1 by the sealing component 2. Then, the operator takes out and puts in the concrete blocks used for highway bridge construction; conversely, the sealing component 2 obstructs the opening side of the detection box 1.

[0042] Furthermore, the two guide grooves 301a are symmetrically arranged, and the guide grooves 301a are T-shaped, while the tempered glass frame 302 is U-shaped;
[0043] The operation process of this embodiment is as follows: After the operator removes the obstruction of the opening side of the test box 1 by the sealing component 2, the concrete block for highway bridge construction is placed on the upper surface of the carrier plate 301. The sealing component 2 is operated to obstruct the opening side of the test box 1. The hydraulic cylinder 104 is operated to make the pressing plate 105 downward to perform strength testing on the concrete block for highway bridge construction. The operator can observe the situation of the concrete block for highway bridge construction during strength testing through the tempered glass plate 201a and the tempered glass frame 302. After the test of the concrete block for highway bridge construction is completed, the obstruction of the opening side of the test box 1 by the sealing component 2 is removed. The tempered glass frame 302 is pulled, and the guide groove 301a moves out of the interior of the test box 1 along the slide rail 107.
