Description

Technical Field

[0001] The utility model relates to the technical field of steel sheet pile installation, in particular to a special locking structure for steel sheet piles. Background Art

[0002] Steel sheet piles are widely used in foundation reinforcement due to their high strength, light weight, good water-proof performance and durability. Steel sheet piles are a structure with locks on both sides. Adjacent steel sheet piles are connected by locks to form a complete linkage structure, which can be freely combined to form a variety of shapes. The difficulty in the construction of steel sheet piles is to ensure that the locks between each pile are tightly connected. In docks, cofferdams, dams or other vulnerable construction projects, there are high requirements for the bite tightness of steel sheet piles.

[0003] Steel sheet piles are a type of steel structure with a linkage device on the edge, which can be freely combined to form a continuous and tight retaining wall or water retaining wall. They have high strength and are easy to drive into hard soil layers. They can be constructed in deep water and, when necessary, can be supported by inclined supports to form a cage with good waterproof performance. They can be formed into cofferdams of various shapes as needed and can be reused many times.

[0004] However, the existing steel sheet piles cannot ensure the stability of the steel sheet pile assembly connection during the enclosing process, so the locking structure used accurately abuts the two assembled ends of the steel sheet pile, which makes the connected ends of the steel sheet pile easy to fall off. At the same time, the locking structure used when in use does not have the function of adjusting the distance of the locking structure according to the thickness of the steel sheet pile assembly part, so the locking structure cannot be applied to steel sheet piles of different thicknesses. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a special locking structure for steel sheet piles. By assembling the steel plate mounting body with a locking plate and a locking rod, the stability of the steel plate mounting body after installation can be improved.

[0009] The locking rod is connected to a slider, and the slider is connected to a rack;

[0010] The rack is movably arranged in the limiting opening, the rotating rod is inserted into the through hole, and the gear is meshed with the rack.

[0011] Slide openings are provided on both sides of the locking plate, a positioning rod is connected inside the slide opening, a slide hole is provided on the metal block, the metal block is movably set on the positioning rod through the slide hole, a spring is sleeved on the positioning rod, one end of the spring is connected to the bottom surface of the slide opening, and the other end is connected to the metal block 3, and a magnetic plate corresponding to the metal block is provided on the rotating plate.

[0012] The rack is connected to one side of the slider, the width of the limiting opening is greater than the strip opening, and the width of the strip opening is 2 mm greater than the width of the slider.

[0013] The through openings are arranged on the two end surfaces of the locking plate, and the two ends of the rack are movably arranged in the through openings.

[0026] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0027] Implementation 1

[0029] The bottom surface of the rotating plate 2 is connected with a rotating rod 202, and the rotating rod 202 is connected with a gear 201;

[0030] The locking rod 4 is connected to a slider 401, and the slider 401 is connected to a rack 402;

[0031] The rack 402 is movably disposed in the limiting opening 105 , the rotating rod 202 is inserted into the through hole 103 , and the gear 201 is meshed with the rack 402 .

[0032] Slide openings 101 are provided on both sides of the locking plate 1, and a positioning rod 102 is connected inside the slide opening 101. A slide hole 301 is provided on the metal block 3, and the metal block 3 is movably set on the positioning rod 102 through the slide hole 301. A spring 302 is inserted into the positioning rod 102, and one end of the spring 302 is connected to the bottom surface of the slide opening 101, and the other end is connected to the metal block 3. A magnetic plate 203 corresponding to the metal block 3 is provided on the rotating plate 2.

[0033] The rack 402 is connected to one side of the slider 401 . The width of the limiting opening 105 is greater than that of the strip opening 104 . The width of the strip opening 104 is 2 mm greater than that of the slider 401 .

[0034] The width of the rack 402 is M, the width of the limiting opening 105 is H, the width of the slider 401 is N, and H=2M+N+2mm.

[0035] The through openings 106 are disposed on both end surfaces of the locking plate 1 , and both ends of the rack 402 are movably disposed in the through openings 106 .

[0036] By assembling the steel plate mounting body 5 with the locking plate 1 and the locking rod 4, the stability of the steel plate mounting body 1 after installation can be improved. At the same time, the rotating plate 2 and the gear 201 drive the movement of the two racks 402, so that the locking rod 4 can be locked according to the thickness of the two steel plate mounting bodies 5 assembled.

[0037] Specifically, the locking plate 1 and the steel sheet pile body 5; the steel sheet pile body 5 is composed of multiple pieces in a staggered combination, the locking plate 1 is located on the upper surface of the connected ends of the two steel sheet pile bodies 5, and the front and rear parts of the lower surface of the locking plate 1 are provided with locking rods 4, the locking rods 4 are located on the front and rear surfaces of the steel sheet pile body 5, and the end surfaces of the steel sheet pile body 5 corresponding to the positions of the locking rods 4 are provided with slots 501, a slider 401 is fixed on the upper end surface of the locking rod 4, and racks 402 are fixed on the opposite end surfaces of the two sliders 401, and the two racks 402 are relatively staggered. A rotating plate 2 is provided in the middle position directly above the locking plate 1, and a gear 201 meshing with the two racks 402 is provided directly below the rotating plate 2.

[0038] Through the arrangement and use of the above-mentioned structure, after a plurality of steel sheet pile bodies 5 are assembled and matched, the locking plate 1 is set at the end position where two steel sheet pile bodies 5 are assembled, and then the two locking rods 4 can be set at the internal position of the groove 501, thereby the two locking rods 4 lock the positions of the two ends of the two steel sheet pile bodies 5 to be connected, and at the same time, when controlling the distance between the two locking rods 4, the rotating plate 2 can be rotated, and then the rotating plate 2 will control the gear 201 to drive the two racks 402 to move relative to or in opposite directions, thereby the rack 402 will drive the slider 401 to move, and the slider 401 will directly drive the locking rod 4 to move, so as to adjust the distance between the two locking rods 4.

[0039] Implementation 2

[0040] Through the mutual adsorption and cooperation between the magnetic plate 203 and the metal block 3, the rotating plate 2 can be limited, thereby ensuring that the distance between the two locking plates 1 will not deviate arbitrarily.

[0041] Specifically, a strip-shaped opening 104 is provided in the middle position of the lower surface of the locking plate 1, and the sliders 401 are slidably set in the internal position of the strip-shaped opening 104. Inside the locking plate 1, a limiting opening 105 connected to the interior of the strip-shaped opening 104 is provided on the upper end surface of the strip-shaped opening 104, and the rack 402 is slidably set in the internal position of the limiting opening 105. Through openings 106 are provided at the positions of the two end surfaces of the locking plate 1 corresponding to the rack 402. The width of the limiting opening 105 is greater than the width of the strip-shaped opening 104. A through hole 103 connected to the interior of the limiting opening 105 is provided in the middle of the upper surface of the locking plate 1. A magnetic plate 203 is fixed on the lower surface of the rotating plate 2. A sliding opening 101 consistent with the front and rear directions of the rotating plate 2 is provided on the front and rear parts of the upper surface of the locking plate 1, and a metal block 3 adsorbed by the magnetic plate 203 is provided inside the sliding opening 101.

[0042] The rotating rod 202 passes through the through hole 103, the upper end of the rotating rod 202 is connected to the rotating plate 2, and the lower end is connected to the gear.

[0043] In order to ensure that the distance between the two locking rods 4 will not be easily adjusted, the magnetic plate 203 can be controlled to be adsorbed and connected with the metal plate. Since the metal block 3 is limited inside the sliding mouth 101, the metal block 3 will limit the magnetic plate 203, so that the rotating plate 2 cannot rotate freely on the upper surface of the locking plate 1. At the same time, when the rotating rod 202 is in the internal position of the rotating mouth 103, the rotating plate 2 will drive the rotating rod 202 to rotate inside the rotating mouth 103. At the same time, the rack 402 is inside the limiting mouth 105, so that the limiting mouth 105 limits the rack 402, so that the rack 402 cannot fall out of the strip mouth 104.

[0044] Implementation 3

[0045] The spring 302 pushes the metal block 3 so that the metal block 3 can be stably adsorbed to the magnetic plate 203 .

[0046] Specifically, a rotating rod 202 is fixed to the lower surface of the magnetic plate 203. The rotating rod 202 rotates through the rotating port 103, and the lower end surface of the rotating rod 202 is fixedly connected to the upper surface of the gear 201. A sliding hole 301 is provided in the middle position of the upper surface of the metal block 3, and the bottom surface of the sliding port 101 is positioned on the rod 102. A spring 302 is fixed to the lower surface of the metal block 3, and the spring 302 is sleeved on the positioning rod 102.

[0047] In order to facilitate the control of the rotation of the rotating plate 2, the metal block 3 can be moved downward inside the sliding mouth 101, and then the metal block 3 will move along the radial direction of the positioning rod 102 through the sliding hole 301, so that the metal block 3 will compress the spring 302. Therefore, through the limitation of the metal block 3 by the positioning rod 102 and the pushing of the metal block 3 by the spring 302, the metal block 3 can be stably adsorbed with the magnetic plate 203, thereby fixing the rotating plate 2.

[0048] After assembling and matching multiple steel sheet pile bodies 5, the locking plate 1 is set at the end position where the two steel sheet pile bodies 5 are assembled, and then the locking rod 4 can be set at the internal position of the groove, so that the two locking rods 4 lock the positions of the two ends of the steel sheet pile body 5, thereby improving the stability of the steel sheet pile body 5 after installation. At the same time, the rotating plate 2 and the gear 201 drive the movement of the two racks 402, and the two racks 402 respectively drive the two locking rods 4 to move relative to each other, so that the locking rod 4 can be locked according to the thickness of the two steel sheet pile bodies 5 assembled.

[0049] By rotating the rotating plate 2, the rotating plate 2 will control the gear 201 to drive the two racks 402 to move relative to or in opposite directions, so that the rack 402 will drive the slider 401 to move, and the slider 401 will directly drive the locking rod 4 to move, so as to adjust the distance between the two locking rods 4, so as to achieve locking according to the thickness of the two steel plates assembled with the main body 1.
