A thrust device for construction of a side plate of a steel hanging box

Abstract

This invention relates to the field of steel caisson construction technology, specifically a thrust-stopping device for the side plate construction of a steel caisson. The device includes a steel caisson base plate, embedded components, support components, orientation adjustment components, pushing components, and limiting components. The support components and pushing components push against the bottom of the assembled side plate, and a sealing gasket ensures the gap between the steel caisson base plate and the assembled side plate is filled tightly. Then, a concrete leveling layer is poured inside the connection between the assembled side plate and the steel caisson base plate. This concrete leveling layer compensates for the inability to weld and seal the assembled side plate to the steel caisson base plate, achieving better water-stopping effect and stability. Simultaneously, the orientation adjustment component allows for selection of a suitable pushing position based on actual conditions when pushing the assembled side plate. Under the action of the limiting components, the support base plate and threaded rod remain stable. When the side plate needs to be removed, the threaded rod moves away from the assembled side plate, facilitating its removal. The operation is simple and convenient.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see the appendix Figure 1-8 This application provides the following five preferred embodiments.

[0034] Example 1

[0035] A thrust-resistant device for the side plate construction of a steel caisson includes a steel caisson base plate 1. A partition platform is provided at the upper end of the steel caisson base plate 1. Assembled side plates 2 are vertically assembled around the partition platform on the steel caisson base plate 1. A horizontally arranged surrounding steel section 6 is provided at the lower end of the side plate 2 away from the partition platform. The assembled side plates 2 are bolted together. Thickened rubber gaskets and sealing gaskets 4 are respectively provided at the assembly joint and on the side of the assembled side plate 2 in contact with the steel caisson base plate 1. A concrete leveling layer 5 is provided at the upper end of the partition platform. The side of the concrete leveling layer 5 is fitted to the side wall of the assembled side plate 2, facilitating assembly. During assembly, the thickened rubber gaskets and mechanical tightening improve the sealing effect. The sealing gaskets 4 prevent the assembled side plate 2 from being compressed and sealed by its own weight when it overlaps with the steel caisson base plate 1. The concrete leveling layer 5 fills and seals the joint between the steel caisson base plate 1 and the assembled side plate 2, thus achieving a sealed connection between the concrete and the metal structural components.

[0036] Example 2

[0037] Based on Embodiment 1, the steel caisson base plate 1 is pre-embedded during design and fabrication to facilitate its use with the supporting base plate 8. The pre-embedded components include several pre-embedded uprights 7, which are vertically and symmetrically arranged on the upper end of the steel caisson base plate 1. The supporting components are sleeved on the pre-embedded uprights 7 and include a supporting base plate 8 and a supporting upright plate 23. An orientation adjustment component is located on the outer periphery of the supporting base plate 8 where the pre-embedded uprights 7 are sleeved. The orientation adjustment component includes a rotating cylinder 9 and an adjusting seat 10. The pre-embedded uprights 7 are arranged in a prismatic structure. The supporting base plate... A rotating hole is vertically through one side of the base plate 8. An adjusting seat 10 is horizontally positioned on the outer periphery of the rotating hole. A rotating cylinder 9 is vertically and movably inserted into the rotating hole. The upper end of the rotating cylinder 9 passes through the adjusting seat 10. A prismatic groove is formed through the center of the rotating cylinder 9. The upper end of the pre-embedded upright 7 is inserted into the prismatic groove. Bolt holes are horizontally corresponding to those on one side of the rotating cylinder 9 and the pre-embedded upright 7. Fixing bolts are horizontally inserted into the bolt holes of the pre-embedded upright 7 and the rotating cylinder 9. An adjusting groove is formed inside the adjusting seat 10, and the rotating cylinder 9 is placed in the adjusting groove. A positioning toothed plate 11 is fitted onto the inner side of the adjusting seat 10. A plurality of positioning teeth are symmetrically arranged on the outer side of the positioning toothed plate 11. A positioning groove is opened on the inner side of the adjusting seat 10. A movable block 12 is movably inserted into the positioning groove. A plurality of meshing teeth 13 are symmetrically arranged on one side of the movable block 12. One side of each meshing tooth 13 of the movable block 12 passes through the positioning groove and is inserted into the adjusting groove. The meshing teeth 13 are respectively inserted between two adjacent positioning teeth of the positioning toothed plate 11. A spring rod 14 is horizontally arranged on one side of the movable block 12 placed in the positioning groove. The movable positioning groove is set, and the spring rod 14 is placed in the positioning groove. On one side, the positioning spring 15 is sleeved. When the support base plate 8 is sleeved with the pre-embedded upright 7 through the rotating cylinder 9, the rotating cylinder 9 remains stationary. When the support base plate 8 needs to be rotated left and right to adjust the position of the threaded rod 25 against the surrounding steel 6, under the elastic force of the positioning spring 15 pushing the movable block 12, the meshing teeth 13 are intermittently inserted into the positioning teeth of the positioning tooth plate 11 to complete the pre-positioning of the support base plate 8, which is convenient to adapt to different pushing positions and usage requirements.

[0038] Example 3

[0039] Based on Embodiment 2, the push-off component includes a threaded rod 25. One side of the threaded rod 25 is threaded through and inserted into the support plate 23. One side of the support plate 23 is horizontally provided with an internal threaded block. One side of the threaded rod 25 is threaded through the internal threaded block and abuts against one side of the surrounding steel 6. The length of the threaded rod 25 extending out of the support plate 23 is controlled by the thread, thereby achieving the abutment strength between the threaded rod 25 and the surrounding steel 6, thus strengthening the stability of the bottom connection between the steel caisson bottom plate 1 and the assembly side plate 2.

[0040] Example 4

[0041] Based on Embodiment 3, the movable block 12 is subject to a movement limit. The limit assembly is vertically installed on one side of the upper end of the adjusting seat 10. The limit assembly includes a limit box 16 and a limit rod 18. The limit box 16 is vertically installed on the upper end of the adjusting seat 10 located on the side of the positioning groove. A U-shaped groove 17 is opened at the upper end of the limit box 16. The support plate 23 is vertically installed on the side of the support base plate 8 near the surrounding steel 6. A rotating handle 26 is provided on one side of the threaded rod 25, and the rotating handle 26 is inserted into the U-shaped groove 17. A spring groove is vertically opened on one side of the limit box 16, and the limit rod 18 is vertically inserted into the spring groove. The upper and lower ends of the movable block 12 are respectively inserted into the U-shaped groove 17 and the positioning groove. The upper end of the movable block 12 is provided with a first limiting groove 19, and the limiting rod 18 is placed in the positioning groove and inserted into the first limiting groove 19. When the rotating handle 26 is inserted into the U-shaped groove 17, the lower end of the rotating handle 26 pushes the limiting rod 18 down. At this time, the limiting rod 18 squeezes the limiting spring 20 through the pressure block, and the lower end is inserted into the first limiting groove 19 of the movable block 12, thereby limiting the movement of the movable block 12. Thus, the relative movement of the support base plate 8 and the rotating cylinder 9 is restricted, and the position of the support base plate 8 is fixed. The operation is simple and convenient.

[0042] Example 5

[0043] Based on Embodiment 4, the stable rotation state of the threaded rod 25 is limited. The upper end of the limiting rod 18 is horizontally provided with a pressure block inside the spring groove. The limiting rod 18 is fitted with a limiting spring 20 at the lower end of the pressure block. A strip groove is opened through the limiting box 16 on one side of the spring groove. A toggle rod 22 is horizontally provided on one side of the pressure block. The toggle rod 22 is inserted through the strip groove. The limiting rod 18 is placed in the U-shaped groove 17 and the upper end is provided with a limiting block 21. Several second limiting grooves 27 are symmetrically opened on the outer circumference of the rotating handle 26. The two sides of the limiting block 21 and the second limiting groove 27 are inclined surfaces and right-angled surfaces, respectively. The limiting block 21 of the limiting rod 18 A second limiting groove 27 is provided on one side of the rotating handle 26, and the end of the rotating handle 26 near the threaded rod 25 is set with a tapered structure. When the rotating handle 26 is inserted into the U-shaped groove 17, the upper limiting block 21 of the limiting rod 18 is inserted into the second limiting groove 27 on one side. When the threaded rod 25 rotates clockwise, under the action of the inclined surfaces of the limiting block 21 and the second limiting groove 27, the threaded rod 25 is normally tightened and abuts against the surrounding steel 6. When the rotating handle 26 and the threaded rod 25 reverse, under the action of the right angle surfaces of the two, the rotating handle 26 and the threaded rod 25 cannot loosen and rotate, thus improving the stability of the threaded rod 25 pushing against the assembled side plate 2.

[0044] When it is necessary to remove the threaded rod 25, press down the lever 22 to control the limit block 21 to retract into the limit box 16, and then remove or loosen the threaded rod 25.

[0045] When the threaded rod 25 loosens and pushes against the surrounding steel 6, the assembled side plate 2 can be detached from the concrete leveling layer 5 by vibration or other means, making it easy to remove the assembled side plate 2. After removing the fixing bolts, the supporting base plate 8 can be removed, which can be reused and is convenient to use.

[0046] Two reinforcing ribs 24 are symmetrically provided on one side of the support plate 23. The reinforcing ribs 24 are arranged in a triangular structure, and the lower end of the reinforcing ribs 24 is welded to the support base plate 8.

[0047] In addition, the supporting base plate 8 and all structures on it can be high-strength, rust-resistant metal structures.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
