Description

Technical Field

[0001] This invention belongs to the field of garage installation and construction technology, and specifically relates to a modular installation method for a mechanical three-dimensional garage structure. Background Technology

[0002] Mechanical automated parking systems occupy less space, have lower construction costs, and eliminate traffic congestion. They offer convenient access, economical operation, easy maintenance, and a small footprint, making them a current solution for addressing the problem of high vehicle traffic and limited parking space. The conventional structure of a mechanical automated parking system is a steel frame system. Due to the structural characteristics of mechanical automated parking systems, the building has a large slenderness ratio and many structural members, but the overall project volume is small. For this type of structure, single-piece frame hoisting is typically used. However, the construction period for each individual frame installation is long, requiring extensive use of construction machinery. The lightweight components result in high installation costs for individual steel components, and there are many high-altitude connection points, leading to lower construction efficiency and precision. Therefore, a targeted design for the installation of mechanical automated parking systems is necessary. Summary of the Invention

[0003] This invention provides a modular installation method for a mechanical automated parking system, which solves technical problems such as convenient hoisting, time saving, and reduction of high-altitude docking points for mechanical automated parking systems.

Each garage in the main structure is set up from bottom to top and the garages are connected by crossbeams. The modular installation method for applying a mechanical automated parking system involves the following steps: Step 1: Based on the characteristics of the main structure of the garage, select a section within the height range of the main structure facade to divide the area into garage area modules, and set each garage area module at the same height. Step 2: Make the assembly frame, and then make the garage unit sub-modules on the assembly frame. Finally, complete the two independent garage unit sub-modules. Step 3: Use a total station to accurately measure the shape of the garage unit sub-module at the endpoints. Use a level and steel ruler to check and adjust the flatness of the garage unit sub-module, control the center misalignment deviation of the horizontal components, and perform overall re-measurement after the garage unit sub-module is formed as a whole. Leave weld gaps at the node positions to control the welding shrinkage size. Perform a second re-measurement after the entire module unit is assembled and welded. Step 4: Hoist the two opposite garage unit sub-modules and place them in the designed positions of the main garage structure; use guy ropes for temporary fixation; use lifting machinery to install the splicing connectors between the two garage unit sub-modules to form a small frame; Step five, the sub-modules of the garage unit are sequentially installed to form small frames, and then connected by the connecting pieces to form the garage area module; Step six, the garage area modules are sequentially constructed from bottom to top, and after the adjacent garage area modules are stably connected and meet the design requirements, the construction of the next garage area module is carried out, until the overall construction of the garage main structure is completed.

[0005] Further, the garage area module comprises the garage unit sub-module, the height of the garage unit sub-module is adapted to the hoisting design requirement, and the garage unit sub-modules are arranged at intervals in the horizontal long direction of the garage unit sub-module.

[0007] Further, the garage diagonal brace is arranged in a V-shaped piece or an inverted V-shaped piece, and the V-shaped piece and the inverted V-shaped piece are arranged alternately in the height direction.

[0010] Further, the assembling jig frame comprises two parallel jig main rods, a jig connecting rod connected between the two jig main rods, and a jig stopper arranged at the top of the jig main rod. The jig main rod and the jig connecting rod form a rectangular frame, and the length and width of the rectangular frame are greater than the length and width of the garage unit sub-module.

Figures 1 to 5 As shown, the modular installation method of the mechanical stereo garage structure is further illustrated, and the specific steps are as follows: Step one, according to the characteristics of the garage main structure 1, the garage main structure 1 is divided into zones in the vertical height range, and each garage zone module 2 is arranged at the same height.

[0018] Each garage zone module 2 contains a garage unit sub-module 21, and the height of the garage unit sub-module 21 meets the hoisting design requirements; and the relatively arranged garage unit sub-modules 21 are arranged at intervals in the horizontal length direction of the garage unit sub-module 21.

The garage diagonal brace 213 is arranged in a V-shaped piece or an inverted V-shaped piece, and the V-shaped piece and the inverted V-shaped piece are arranged alternately in the height direction; wherein the two feet of the V-shaped piece or the inverted V-shaped piece are arranged at the inside corner of the connection between the garage column 211 and the garage beam 212, and the top point is arranged at the middle of the garage beam 212.

[0020] Step two, make a splicing jig 3, make a garage unit sub-module 21 on the splicing jig 3, and then complete two independent garage unit sub-modules 21.

[0021] In this embodiment, the splicing jig 3 contains two parallel arranged jig main rods 31, a jig connecting rod 32 connected between the two jig main rods 31, and a jig stopper 33 arranged at the top of the jig main rod 31; the jig main rod 31 and the jig connecting rod 32 form a rectangular frame, and the length and width of the rectangular frame are greater than the length and width of the garage unit sub-module 21.

[0022] Among them, the jig main rod 31 is made of two 9m long H400x400x13x21 type steels, and the jig connecting rod 32 is made of C14 channel steel. The two ends of the jig connecting rod 32 are connected to the middle part of the vertical plate of the jig main rod 31.
