Description

Technical Field

[0001] The invention relates to the technical field of vertical underground garages, in particular to a construction method for a cast-in-place pipe joint tongue and groove in a vertical underground garage. Background Art

[0002] The vertical underground garage is an intelligent parking facility that combines three-dimensional parking technology with underground space development. Its core feature is that it uses a multi-layer design in the vertical direction and an automated mechanical system (such as elevators, rotating platforms, handling robots, etc.) to efficiently park vehicles in parking spaces at different depths underground. Compared with traditional underground garages, it pays more attention to the vertical utilization of space and is especially suitable for urban central areas with tight land resources. During the construction of the vertical underground garage, the tongue and groove of the cast-in-place pipe section is usually opened manually after the cast-in-place pipe section is completed, which is inefficient and difficult to control in shape.

[0003] Therefore, a construction method for the tongue and groove of a cast-in-place pipe section in a vertical underground garage is needed so that the tongue and groove can be opened simultaneously when constructing the cast-in-place pipe section. Summary of the invention

The construction method utilizes an arrangement structure, which is composed of a number of boxes with adjustable sizes. A concave-convex structure is formed between the boxes. The concave-convex structure serves as a casting template for the tongue and groove of the cast-in-place pipe section, and the opening of the tongue and groove is achieved while the cast-in-place pipe section is being constructed.

DETAILED DESCRIPTION

[0014] The features of the present invention and other related features are further described in detail below through embodiments in conjunction with the accompanying drawings to facilitate understanding by those skilled in the art: Example: Figures 1 to 11 As shown, this embodiment relates to a construction method for the tongue and groove of a cast-in-place pipe section in a vertical underground garage, which utilizes an arrangement structure, which includes a plurality of boxes 1 of adjustable size, and a plurality of boxes 1 are connected by bolts to form a concave-convex structure, which can be assembled into various shapes according to needs, and the concave-convex structure is used as a casting template for the tongue and groove of the cast-in-place pipe section. The construction method mainly includes the following steps: S1: According to the design requirements, several boxes 1 are assembled into a concave-convex structure (casting template for the tongue and groove of the cast-in-place pipe section), and the casting template of the cast-in-place pipe section is installed (the casting template of the cast-in-place pipe section can also be assembled through the boxes 1).

[0015] Specifically, Figures 1 to 11As shown, the concave-convex structure is connected to the top ring beam 5 through a horizontal tie rod 3, and the concave-convex structure is connected to the prefabricated pipe segment 6 through a vertical tie rod 4. The horizontal tie rod 3 and the vertical tie rod 4 are used to fix the concave-convex structure, and the cast-in-place pipe segment and the prefabricated pipe segment 6 are both square pipe segments. A square inflatable airbag 2 is installed inside the box body 1. When casting the cast-in-place pipe segment, the square inflatable airbag 2 is inflated to improve the overall compressive resistance of the box body 1. The square inflatable airbag 2 is composed of a first rubber layer 21, a steel wire layer 22 and a second rubber layer 23 from the outside to the inside to ensure the overall strength of the square inflatable airbag 2. The box body 1 is composed of six box panels 11 with adjustable length and width. The box panels 11 are connected by bolts. The box panel 11 includes four overlapping box panel components 111. A first mounting groove 1111 is opened on the left rear side of the top of the box panel component 111, and a second mounting groove 1112 is opened on the right side of the bottom end of the box panel component 111. The first plate body 1113 at the top right side of the box panel component 111 cooperates with the first mounting groove 1111, and the second plate body 1114 at the bottom left rear side of the box panel component 111 cooperates with the second mounting groove 1112.

[0016] The four box plate assemblies 111 are respectively the first box plate assembly a, the second box plate assembly b, the third box plate assembly c and the fourth box plate assembly d. The first plate body 1113 of the first box plate assembly a is installed in the first installation groove 1111 of the second box plate assembly b, the first plate body 1113 of the second box plate assembly b is installed in the first installation groove 1111 of the third box plate assembly c, the first plate body 1113 of the third box plate assembly c is installed in the first installation groove 1111 of the fourth box plate assembly d, and the first plate body 1113 of the fourth box plate assembly d is installed in the first installation groove 1111 of the first box plate assembly a. The first plate body 1113 can move in the first installation groove 1111. By adjusting the position of each first plate body 1113 in the first installation groove 1111, the size of the box plate 11 is adjusted, thereby adjusting the size of the box body 1. The first plate body 1113 is fixed in the first installation groove 1111 by the locking bolt 7. A layer of sealing rubber pad is provided on the outer surface of the box plate assembly 111, which plays a sealing role to prevent the slurry from flowing out during pouring. When the first plate body 1113 is partially installed in the first installation groove 1111, there is a square hole 112 in the center of the box plate 11, and a rubber block 8 is installed in the square hole 112. The two ends of the rubber block 8 are large and the middle part is small. The middle part of the rubber block 8 is stuck in the square hole 112, wherein the ends and the middle part of the rubber block 8 are both square, and the rubber block 8 plays a sealing role to prevent the slurry from flowing out during pouring; when the first plate body 1113 is completely installed in the first installation groove 1111, the center of the box plate 11 is sealed (no need to install the rubber block 8).

[0017] S2: Inflate the square inflatable airbag 2 and make the square inflatable airbag 2 reach a certain pressure.

[0018] S3: Pour concrete to form a cast-in-place pipe section with tongue and groove.

[0019] S4: Remove the casting formwork of the concave-convex structure and cast-in-place pipe sections.

[0020] The beneficial technical effect of this embodiment is that the tongue and groove are opened while the cast-in-place pipe section is constructed.

[0021] Although the above embodiments have described in detail the concepts and embodiments of the present invention with reference to the accompanying drawings, ordinary technicians in this field can recognize that various improvements and changes can still be made to the present invention without departing from the scope of the claims, so they are not described one by one here.
