[0019] The specific embodiment of the utility model is further explained in detail by the description of the embodiment by comparing with the drawings, the purpose is to help the technical personnel in the field to have more complete, accurate and deep understanding to the inventive concept and technical scheme of the application, and help its implementation.

[0020] As Figure 1 And Figure 2 The construction device for the assembly type subway station precision strip, as shown in the drawings, includes strip template 1, strip template 1 is provided with adjusting rod 2 between, adjusting rod 2 includes first rod body 3 and second rod body 4, first rod body 3 and second rod body 4 are detachably connected, and the side of strip template 1 is provided with fixed structure.

[0021] The two strip templates 1 are oppositely arranged, and the area between the two strip templates 1 is the construction area of the precision leveling strip. The adjusting rod 2 is fixed with the strip template 1, and the adjusting rod 2 is a detachable structure, which is convenient for transportation before and after construction, length adjustment during construction, and recycling after the construction of the precision leveling strip is completed. The fixing structure is located outside the strip template 1 and does not affect the construction process of the precision leveling strip, and provides horizontal positioning and support for the strip template 1.

[0022] As shown in Figure 1 and Figure 2 , one end of the first rod body 3 is provided with a nut 5, and one end of the second rod body 4 is provided with a screw rod 6. The screw rod 6 cooperates with the nut 5, and the end of the screw rod 6 extends into the first rod body 3. The adjusting rod 2 adjusts the distance between the strip templates 1 through the screw rod and the nut 5, thereby adjusting the length of the precision leveling strip to meet the construction requirements. Since the first rod body 3 and the second rod body 4 are detachably connected, after the adjusting rod 2 is disassembled into the first rod body 3 and the second rod body 4, the length is reduced, which is convenient for transportation and batch placement, reduces transportation cost and construction difficulty; the first rod body 3 and the second rod body 4 are hollow structures, which reduce the weight, the axial movement area of the screw rod is located inside the adjusting rod 2, and the influence on external construction is reduced.

[0023] As shown in Figure 3 , the fixing structure includes a bolt 8, the outside of the strip template 1 is provided with a bracket 7, the bolt 8 is arranged at the end of the bracket 7, a sleeve 9 is arranged in the base cushion layer 11, and the bottom end of the bolt 8 is threadedly connected with the sleeve 9. Since the sleeve 9 is pre-buried in the base cushion layer 11 and the opening end is flush with the base cushion layer 11, the position does not change, the distance between the strip templates 1 is determined, and the bolt 8 is further screwed into the sleeve 9 to cooperate with the sleeve 9, thereby limiting the axial and radial movement of the bolt 8, achieving horizontal positioning of the strip template 1, and ensuring the stability of the distance between the strip templates 1, so that the flatness of the precision leveling strip is not affected by other factors, thereby ensuring the assembly accuracy of the prefabricated part in subsequent construction. The fixing structure adopts threaded connection, the applied force is easy to adjust, the bolt has an axial extrusion effect on the bracket 7, which limits the vertical movement of the strip template 1 and can control the elevation of the base cushion layer to a certain extent, and in combination with the horizontal positioning effect of the strip template 1, the stability of the strip template 1 is further improved; the fixing structure is used on both sides of the strip template 1, which is conducive to leveling between the two oppositely arranged strip templates 1, and a gasket 10 is sleeved on the bolt to avoid deformation of the bracket 7 due to excessive tightening force.

[0024] As shown in Figure 1 and Figure 2As shown in the figure, the screw rod 6 and the nut 5 are located in the middle of the adjusting rod 2. The disassembly end is arranged in the middle of the adjusting rod 2, so that the length of the first rod body 3 and the second rod body 4 is reduced, that is, the volume of the two rod bodies is reduced, and transportation and storage are facilitated; since the disassembly end is arranged in the middle of the adjusting rod 2, it serves as a visual positioning reference, and in the construction process, the construction personnel can observe the disassembly end in the middle of the adjacent adjusting rod 2 to timely adjust the strip formwork 1 or the precision strip which is not accurately positioned, so as to ensure the precision.

[0025] As shown in the figure, Figure 2 The adjusting rods 2 are arranged at equal intervals between the strip formworks 1. The adjusting rods 2 are arranged at equal intervals in sequence, so as to ensure the elevation precision of the foundation cushion layer and effectively reduce the cumulative error in the later assembly.

[0026] As shown in the figure, Figure 3 The bracket 7 has a triangular structure. The above structure improves the stability of the bracket 7, ensures that the axis of the bolt 8 is vertical, and the bolt 8 can be accurately aligned with the sleeve 9.

[0027] As shown in the figure, Figure 1 The strip formwork 1 is a square tube. The strip formwork 1 adopts the square tube to improve the structural strength, is not easy to deform, reduces the weight, and has low cost.

[0028] The construction device for the fabricated subway station precision strip replaces the use of the existing fixed control tool, the adjusting rod 2 is designed as a detachable structure, the size is reduced, the transportation and transportation and construction operation convenience are improved, the construction device can be recycled, the use cost is reduced, the bolt 8 and the sleeve 9 are arranged to transversely and vertically position the strip formwork 1, the stability of the interval of the strip formwork 1 after the adjustment of the precision strip is ensured, the flatness of the foundation cushion layer is ensured, and the assembly precision of the subsequent wall prefabricated component is improved.
