Description

Technical Field

[0001] This invention relates to the field of subway station technology, specifically to a prefabricated subway station structure. Background Technology

[0002] On-site cast-in-place structures are greatly affected by factors such as construction technology, curing conditions, weather, and temperature, making it difficult to control concrete quality. However, in recent years, with my country's vigorous development of prefabricated buildings, prefabrication methods have gradually been applied in subway station projects. Prefabricated subway stations can achieve standardization in design, prefabrication of components, and construction, significantly shortening the construction period, reducing the land occupied by material storage and processing, and minimizing on-site operations such as concrete pouring. This saves labor, reduces construction waste, and offers advantages such as being green, environmentally friendly, and energy-saving.

[0003] Currently, traditional prefabricated subway station designs still have some structural problems. The assembly of the prefabricated main components is relatively inconvenient, and the stability is poor when the main components are assembled. In response to these problems, the inventors have proposed a prefabricated subway station structure to solve them. Summary of the Invention

Grouting material is injected into the connection between the first grouting material 44 and the first grouting sleeve 41. The injected grouting material enters the first grouting sleeve 41 and surrounds the first reinforcing bar 43 and the second reinforcing bar 46. When the grouting material solidifies, the side plate 2 and the bottom plate 1 are assembled.

[0036] By adopting the above technical solution, grout is injected into the connection between the first grouting material 44 and the first grouting sleeve 41. The injected grout enters the first grouting sleeve 41 and surrounds the first steel bar 43 and the second steel bar 46. After the grout solidifies, the side plate 2 and the bottom plate 1 are assembled.

[0037] The second assembly mechanism 5 includes a second grouting sleeve 51. The two side plates 2 are provided with evenly distributed second slots 52 on the side near the top plate 3. The outer wall of the second grouting sleeve 51 is fixedly connected to the inner wall of the second slot 52. A third steel bar 53 is fixedly installed at one end of the second grouting sleeve 51.

[0038] By adopting the above technical solution and setting the second grouting sleeve 51 and the third reinforcing bar 53, it is convenient to connect the top plate 3 and the side plate 2 for subsequent grouting.

[0039] Two second grouting materials 54 are fixedly installed on the side of the top plate 3 near the side plate 2. The side of the second grouting material 54 away from the top plate 3 is in contact with the upper surface of the side plate 2. The surfaces of the two second grouting materials 54 are provided with evenly distributed second perforations 55.

The end of the fourth steel bar 56 away from the top plate 3 passes through the second perforation 55 and the second grouting sleeve 51 and is in contact with one end of the third steel bar 53. Grouting material is injected into the connection between the second grouting material 54 and the second grouting sleeve 51. The injected grouting material enters the second grouting sleeve 51 and surrounds the third steel bar 53 and the fourth steel bar 56. After the grouting material solidifies, the top plate 3 and the side plate 2 are assembled.

[0040] By adopting the above technical solution, grout is injected into the connection between the second grouting material 54 and the second grouting sleeve 51. The injected grout enters the second grouting sleeve 51 and surrounds the third steel bar 53 and the fourth steel bar 56. After the grout solidifies, the top plate 3 and the side plate 2 are assembled.

[0041] The connecting assembly 6 includes a rotating rod 61. A bottom plate 1 has evenly distributed grooves 62 on its side away from the side plate 2. Evenly distributed damping bearings 63 are fixedly installed on the inner wall of the grooves 62. One end of the rotating rod 61 is fixedly connected to the inner wall of the damping bearings 63. A rotating roller 64 is fixedly installed on the outer wall of the rotating rod 61. Two first insertion rods 65 are fixedly installed on the outer wall of the rotating roller 64. When the bottom plate 1 is hoisted, the workers manually pull the first insertion rods 65. The first insertion rods 65 rotate around the axis of the rotating rod 61 via the rotating roller 64, causing the first insertion rods 65 to open and face vertically downwards. When the bottom plate 1 is hoisted into the subway station pit, the first insertion rods 65 are inserted into pre-drilled through holes in the subway station pit. Concrete is injected into the through holes, surrounding the first insertion rods 65 and improving the stability of the bottom plate 1 after connection with the subway station pit.

[0042] By adopting the above technical solution, when hoisting the base plate 1, the workers manually pull the first insertion rod 65. The first insertion rod 65 rotates around the axis of the rotating rod 61 via the rotating roller 64, so that the first insertion rod 65 opens and faces vertically downward. When the base plate 1 is hoisted into the subway station pit, the first insertion rod 65 is inserted into the reserved through hole in the subway station pit. By injecting concrete into the through hole, the concrete surrounds the first insertion rod 65, improving the stability of the base plate 1 after it is connected to the subway station pit.

[0043] The outer wall of the first insertion rod 65 is fixedly equipped with a uniformly distributed first reinforcing steel bar 66. By setting the first reinforcing steel bar 66, the stability of the first insertion rod 65 after being inserted into the precast concrete can be improved.

[0044] By adopting the above technical solution and setting the first reinforcing steel bar 66, the stability of the first insertion rod 65 after being inserted into the precast concrete is improved.

[0045] The support assembly 7 includes a hollow rod 71. Two cavities 72 are formed on one side of each of the two side plates 2. The hollow rod 71 passes through the cavity 72 and is fixedly connected to the inner wall of the cavity 72. A movable rod 73 is provided on the inner wall of the hollow rod 71. A support plate 74 is fixedly installed at the end of the movable rod 73 away from the hollow rod 71. Evenly distributed second insertion rods 75 are fixedly installed on the side of the support plate 74 away from the movable rod 73. After the side plates 2 and the bottom plate 1 are assembled, the second insertion rods 75 are horizontally inserted into the pre-reserved through holes on the side of the subway station pit, and concrete is injected into the through holes, surrounding the second insertion rods 75. To improve the stability of the side plate 2, the inner wall of the hollow rod 71 has two grooves 77, and a slider 78 is slidably connected to the inner wall of the groove 77. The slider 78 can slide horizontally along the inner wall of the groove 77. Two adjacent sliders 78 are fixedly connected to one end of a movable rod 73. The slider 78 can keep the movable rod 73 moving horizontally. A telescopic spring 79 is fixedly installed on the inner wall of the hollow rod 71. One end of the telescopic spring 79 is fixedly connected to one end of the movable rod 73. By setting the telescopic spring 79, the distance between the second plug rod 75 and the side plate 2 can be easily adjusted.

[0046] By adopting the above technical solution, by setting the slide groove 77 and the slider 78, the slider 78 can keep the movable rod 73 moving in the horizontal direction. By setting the telescopic spring 79, the telescopic spring 79 can easily adjust the distance between the second plug rod 75 and the side plate 2. After the side plate 2 and the bottom plate 1 are assembled, the second plug rod 75 is horizontally inserted into the through hole reserved on the side of the subway pit, and concrete is injected into the through hole. The concrete surrounds the second plug rod 75, improving the stability of the side plate 2.

[0047] The outer wall of the second insertion rod 75 is fixedly equipped with a uniformly distributed second reinforcing steel bar 76. By setting the second reinforcing steel bar 76, the stability of the second insertion rod 75 after being inserted into the precast concrete can be improved.

[0048] By adopting the above technical solution and setting a second reinforcing steel bar 76, the stability of the second insertion rod 75 after being inserted into the precast concrete is improved.

[0049] Working principle: When it is necessary to assemble the bottom plate 1, side plate 2 and top plate 3, the workers first inject concrete into the through hole in the inner wall of the subway station pit, and then manually pull multiple first plug-in rods 65. The multiple first plug-in rods 65 rotate around the axis of the corresponding rotating rod 61 through the corresponding rotating roller 64, so that the multiple first plug-in rods 65 open and face vertically downward.

[0050] When the base plate 1 is hoisted into the subway station pit, multiple first plug-in rods 65 are vertically inserted into the pre-reserved through holes in the subway station pit. The injected concrete surrounds the multiple first plug-in rods 65, improving the stability of the base plate 1 after it is connected to the subway station pit.

[0051] Subsequently, grout is injected into multiple first grouting sleeves 41 on the upper surface of the base plate 1 and filled. Then, two side plates 2 are hoisted by an external crane. Multiple second reinforcing bars 46 on the lower end face of the two side plates 2 are vertically inserted into the corresponding first grouting sleeves 41 and contact the upper ends of the first reinforcing bars 43 in the multiple first grouting sleeves 41. After the grout in the multiple first grouting sleeves 41 solidifies, the two side plates 2 and the base plate 1 are assembled, thereby effectively improving the convenience of assembling the side plates 2 and the base plate 1.

[0052] While assembling the side plate 2 and the bottom plate 1, concrete is injected into the through holes of the subway pit sidewall, and multiple second plug rods 75 on one side of the two side plates 2 are horizontally inserted into multiple through holes. After the concrete solidifies, the multiple second plug rods 75 are fixed to the sidewall of the subway pit, thereby improving the stability of the side plate 2.

[0053] After the two side plates 2 and the bottom plate 1 are assembled, the workers inject grout into the multiple second grouting sleeves 51 on the upper surface of the two side plates 2 respectively. Then, the top plate 3 is hoisted by an external crane. The multiple fourth steel bars 56 on the lower surface of the top plate 3 are vertically inserted into the multiple second grouting sleeves 51 and contact the upper ends of the multiple third steel bars 53 in the multiple second grouting sleeves 51. After the grout in the multiple second grouting sleeves 51 dries, the assembly of the top plate 3 and the two side plates 2 is completed. This facilitates the assembly of the bottom plate 1, side plates 2 and top plate 3, thereby effectively improving the convenience of assembling the bottom plate 1, side plates 2 and top plate 3.
