[0001] The utility model belongs to the technical field of trestle boards, and particularly relates to a reinforced trestle board for deep foundation pit construction. Background Technique
[0002] Deep foundation pit construction is an important engineering technology in the construction industry. It mainly involves excavating foundation pits with a depth exceeding 5 meters (including 5 meters), or projects with a depth less than 5 meters but with particularly complex geological conditions, surrounding environments, and underground pipelines. A trestle board, also known as a bridge deck or a steel bridge deck, is a steel plate used to build a temporary bridge. The reinforced trestle board for deep foundation pit construction should have higher load-bearing capacity and stability to cope with more complex construction environments and higher construction requirements.
[0003] The following problems also exist in the combination process of traditional trestle boards:
[0004] After two trestle boards are spliced, since the splicing involves the connection of multiple components, its strength may be weaker than that of the trestle board body. To ensure safety, it needs to be improved. In addition, in the prior art, when two trestle boards are spliced together, additional components need to be installed to firmly assemble the two together. The non-integrated setting means that more installation steps may be required, which increases the complexity of the operation, may lead to an extension of the construction time, and reduces work efficiency. At the same time, these additional components may also increase costs because these components need to be purchased, transported, and stored. Content of the Utility Model

Specific embodiments
[0020] In order to clearly and completely describe the purpose, technical solution of the present utility model and make the advantages more clear, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.
[0021] Embodiment 1
[0022] Please refer to Figures 1 to 5 , the present utility model provides a technical solution: a reinforced trestle board for deep foundation pit construction, including a trestle board body 1. The outer walls on both sides of the trestle board body 1 are both provided with the first built-in groove 5 and the second built-in groove. A first hollow body 2, a second hollow body 4 and a diamond structure are fixedly connected between the top end and the bottom end of the inner wall of the trestle board body 1. Four top covers 14 are hinged to the top of the trestle board body 1. A first strengthening structure is arranged inside the first hollow body 2, and a second strengthening structure is arranged inside the second hollow body 4. The first strengthening structure and the second strengthening structure can be assembled together through adjustment. Two symmetrically distributed blocking doors 6 are clamped on both sides of the trestle board body 1; after each trestle board body 1 is closely attached to each other, each top cover 14 is opened respectively, each blocking door 6 is first pulled out, and then each first strengthening structure and each second strengthening structure are respectively adjusted to assemble the two together, and then each blocking door 6 is placed in the opened groove to complete the assembly, without adding additional components, the operation is simple and fast, and a stable triangular structure is formed at the connection of the two trestle board bodies 1, thereby enhancing the stability.
[0023] Example 2
[0024] Please refer to Figures 1 to 5 , on the basis of Example 1, the diamond structure includes two bending blocks 3. The two bending blocks 3 are fixedly connected facing each other, and the cross-section of the formed whole is in a square shape. The bottom end of one bending block 3 is fixedly connected to the bottom end of the inner wall of the trestle board body 1, and the top of the other bending block 3 is fixedly connected to the top end of the inner wall of the trestle board body 1. The two bending blocks 3 are simultaneously fixedly connected between the hollow body 1 and the hollow body 2 4. A vertical plate is fixedly connected between the two bending blocks 3.
[0025] Taking the same trestle board body 1 as a unit, the interiors of the hollow bodies 1 and the hollow bodies 2 4 opened inside the same trestle board body 1 do not communicate with each other. After two adjacent trestle board bodies 1 are installed, as shown in the attached instructions Figure 1 , the interior of the hollow body 1 of one trestle board body 1 communicates with the interior of the hollow body 2 4 of the other trestle board body 1. Through the set diamond structure and vertical plate, the diamond structure is further divided into two triangular parts, further improving the stability.
[0026] Example 3
[0027] Please refer to Figures 1 to 5 , on the basis of Example 2, the built-in groove 1 5 is opened in the inner cavity of the hollow body 1. The inner walls on both sides of the hollow body 1 and the hollow body 2 4 are respectively provided with a sliding groove 1 9, a sliding groove 2 18 and an initial groove 13. A combined plate 7 is arranged inside the hollow body 1, and the combined plate 7 is slidably connected between the two sliding grooves 1 9. A V-shaped block 15 is arranged inside the hollow body 2 4. Two circular blocks are fixedly connected to the outer walls on both sides of the V-shaped block 15, and the outer walls of the circular blocks are slidably connected to the inner walls of the sliding groove 2 18. Two rectangular openings 10 that are far away from each other and symmetrical about the midline of the top surface of the combined plate 7 are opened at the top of the combined plate 7. Two reinforcing grooves 8 that are far away from each other and symmetrically distributed are opened at one end of the combined plate 7. The cross-section of the reinforcing groove 8 is in a T shape. Two groups of sliding parts are fixedly connected to the top end of the V-shaped block 15. Each group of sliding parts includes two T-shaped blocks 16 that are far away from each other and symmetrically distributed. The T-shaped blocks 16 are adapted to the reinforcing grooves 8 and the ends close to each other are chamfered. The initial groove 13 can form a clamping relationship with the blocking door 6. Two symmetrically distributed and penetrating limiting grooves 11 are opened at the top of the combined plate 7. Stable grooves 12 are opened at the bottom ends of the inner walls of the hollow body 1 and the hollow body 2 4. Two symmetrically distributed reinforcing grooves 17 are opened at the inclined end of the V-shaped block 15. The reinforcing grooves 17 are through-shaped and the opening direction is vertical. The blocking door 6 can form a clamping relationship with the limiting grooves 11 and the stable grooves 12. Each top cover 14 is respectively located above each hollow body 1 and the hollow body 2 4.
[0028] Along the hinge joints between each top cover 14 and the top of the trestle board body 1, turn each top cover 14 upward. Since through holes are provided at the top of the top cover 14, the rotation process becomes convenient. After that, it is necessary to pull out each blocking door 6 so that it completely disengages from the inside of each initial groove 13. First, drive the V-shaped block 15 so that it slides along the inside of the second hollow body 4 in the direction of another trestle board body 1. Through the provided second chute 18 and the round block, the displacement range of the V-shaped block 15 is further restricted. It cannot generate offsets in other directions and can only move left and right in the horizontal direction, while improving the stability of the V-shaped block 15 during displacement. Since the second chute 18 is also provided inside the first hollow body 2 on another trestle board body 1, the V-shaped block 15 can be displaced into the inside of the first hollow body 2. When half of the V-shaped block 15 enters the inside of the first hollow body 2, the control of it can be stopped. After that, through the provided rectangular opening 10, the combined board 7 can slide along the inside of the first chute 9. At this time, it is necessary to displace the combined board 7 into the inside of the above-mentioned second hollow body 4. Since the first chute 9 is also provided inside the second hollow body 4, the combined board 7 can slide and be clamped into the inside of the second hollow body 4. Similarly, when half of it is displaced into the inside of the second hollow body 4, the adjustment is stopped. Finally, insert the two blocking doors 6 into the inside of the initial groove 13 on the first hollow body 2 and the initial groove 13 on the second hollow body 4 respectively to complete the operation. During the above process, the blocking door 6 will pass through the limiting groove 11 provided on the combined board 7 and the reinforcing groove 17 provided at the inclined end of the V-shaped block 15, and finally be clamped inside the stable groove 12 provided at the bottom end of the inner wall of the second hollow body 4 or the first hollow body 2, so that the overall combination of the combined board 7 and the V-shaped block 15 is in a fixed state. It is located exactly in the center of the connection between the two trestle board bodies 1 and is in a stable triangle as a whole, greatly improving the stability. During the combination of the V-shaped block 15 and the combined board 7, each T-shaped block 16 will be completely clamped into the inside of the two reinforcing grooves 8, improving the firmness. The chamfered reinforcing grooves 8 and the T-shaped blocks 16 make their combination smoother.
[0029] In actual use, along the hinge joints between each top cover 14 and the top of the trestle board body 1, each top cover 14 is turned upwards. Since through holes are provided at the top of the top cover 14, the rotation process becomes convenient. After that, it is necessary to pull out each blocking door 6 to completely remove it from the inside of each initial groove 13. First, drive the V-shaped block 15 to slide along the inside of the second hollow body 4 towards the direction of another trestle board body 1. Through the provided second chute 18 and the round block, the displacement range of the V-shaped block 15 is further restricted, and it cannot deviate in other directions and can only displace left and right in the horizontal direction. At the same time, the stability of the V-shaped block 15 during displacement is improved. Since the second chute 18 is also provided inside the first hollow body 2 on another trestle board body 1, the V-shaped block 15 can displace into the inside of the first hollow body 2. When half of the V-shaped block 15 enters the inside of the first hollow body 2, the control of it can be stopped. After that, through the provided rectangular opening 10, the combined board 7 can slide along the inside of the first chute 9. At this time, it is necessary to displace the combined board 7 towards the inside of the above-mentioned second hollow body 4. Since the first chute 9 is also provided inside the second hollow body 4, the combined board 7 can slide and be clamped into the inside of the second hollow body 4. Similarly, when half of it displaces into the inside of the second hollow body 4, the adjustment is stopped. Finally, the two blocking doors 6 are respectively inserted into the inside of the initial groove 13 on the first hollow body 2 and the initial groove 13 on the second hollow body 4 to complete the operation. During the above process, the blocking door 6 will pass through the limiting groove 11 provided on the combined board 7 and the reinforcing groove 17 provided at the inclined end of the V-shaped block 15, and finally be clamped inside the stable groove 12 provided at the bottom end of the inner wall of the second hollow body 4 or the first hollow body 2, so that the overall combination of the combined board 7 and the V-shaped block 15 is in a fixed state. It is located exactly in the middle of the connection between the two trestle board bodies 1 and is in a stable triangle as a whole, greatly improving the stability. After that, each turned-up top cover 14 is restored.
