Description

Technical Field

[0001] The invention belongs to the technical field of garage installation and construction, and in particular relates to a modular installation method for a mechanical stereo garage structure. Background Art

[0002] Mechanical stereo garages occupy a small area, have low construction costs, and avoid traffic jams. They are easy to access, economical to operate, easy to maintain, and occupy a small area. They are a solution to the current situation of a large number of vehicles and a small parking area. The structure of a mechanical stereo garage is usually a steel frame system. Due to the structural characteristics of mechanical stereo garages, the building has a large slenderness ratio and many structural members, but the construction volume is small. For this type of mechanical stereo garage structure, the frame is usually hoisted as a single piece. The construction period of a single piece is long, the construction machinery is used for a long time, the components are light, the installation cost of a single steel member is high, and there are many high-altitude docking points, which reduces construction efficiency and accuracy. Therefore, a targeted design for the installation of the mechanical stereo garage structure is required. Summary of the Invention

[0003] The present invention provides a modular installation method for a mechanical stereoscopic garage structure, which is used to solve technical problems such as convenient lifting of the mechanical stereoscopic garage structure, saving time and reducing high-altitude docking points.

[0004] To achieve the above object, the present invention adopts the following technical solutions: The main structure of the garage is a frame steel structure. Each garage in the main structure is set up from bottom to top and connected by beams. The modular installation method of the mechanical stereo garage structure is applied, and the specific steps are as follows: Step 1: Based on the characteristics of the main structure of the garage, select the area within the height range of the main structure of the garage to divide it into zones. The zones are used as garage area modules, and each garage area module is set at the same height. Step 2: Make an assembly frame, make garage unit submodules on the assembly frame, and then complete two relatively independent garage unit submodules; Step 3: Use a total station to accurately measure the end points of the garage unit submodule. Use a spirit level and a steel ruler to check and adjust the flatness of the garage unit submodule and control the center misalignment deviation of the horizontal components. After the garage unit submodule is formed as a whole, re-measure the entire unit. Reserve weld gaps at the node positions to control the welding shrinkage size. After the entire module unit is assembled and welded, re-measure the entire unit again. Step 4: Hoist the two opposing garage unit submodules and place them at the designed location of the garage main structure; use guy ropes to temporarily fix them; use lifting machinery to install the splicing connectors between the two garage unit submodules to form a small frame; Step 5: The sub-modules of the garage units in the same partition are sequentially installed to form small frames, and then connected through connectors to form a garage area module; Step 6: The garage area modules are constructed from bottom to top. After the adjacent garage area modules are firmly connected and meet the design requirements, the next garage area module is constructed until the overall construction of the garage main structure is completed.

[0005] Furthermore, the garage area modules all include garage unit submodules, the height of the garage unit submodules adapts to the hoisting design requirements; and the relatively arranged garage unit submodules are spaced apart upwardly along the horizontal length of the garage unit submodules.

[0006] Furthermore, the garage unit submodule includes two parallel garage columns, a garage beam connected between the garage columns, a garage diagonal brace between the upper and lower garage beams, and a garage reserved joint provided at the connection between the garage columns and the garage beam and located on the garage columns; The garage beams are spaced apart in the height direction of the garage columns, and the spacing distance is adapted to the height of each floor of the garage.

[0007] Furthermore, the garage diagonal braces are arranged in V-shaped pieces or inverted V-shaped pieces, and the V-shaped pieces and inverted V-shaped pieces are alternately arranged in the height direction; The two legs of the V-shaped member or the inverted V-shaped member are arranged at the inner corner where the garage column and the garage beam are connected, and the apex is arranged at the middle of the garage beam.

[0008] Furthermore, the splicing connector connects the garage reserved joints of two opposite garage unit submodules, and the splicing connector includes a horizontal connecting rod and a diagonal bracing rod arranged on the upper and lower adjacent horizontal connecting rods.

[0009] Furthermore, the butt connector is connected to the garage reserved joint between adjacent small frames. The butt connector is a straight rod. The material and style of the butt connector are set in accordance with the garage beams. The butt connector is set in accordance with each garage beam in the height direction.

[0010] Furthermore, the assembled tire frame comprises two tire frame main rods arranged in parallel, a tire frame connecting rod connected between the two tire frame main rods, and a tire frame stopper arranged on the top of the tire frame main rods; The tire frame main rod and the tire frame connecting rod together form a rectangular frame, and the length and width of the rectangular frame are greater than the length and width of the garage unit submodule.

[0011] Furthermore, the tire frame stopper is an L-shaped member, the horizontal portion of which is fixedly connected to the top of the tire frame main rod; two tire frame stoppers are provided at both ends of each tire frame main rod, and the two tire frame stoppers are arranged opposite to each other; The distance between the vertical parts of the L-shaped piece corresponds to the garage columns.

[0012] Furthermore, a garage bottom connecting piece is provided at the bottom of the garage main structure, and a garage top connecting piece is provided at the top; the garage bottom connecting piece and the garage top connecting piece are both rods, and are both fixedly connected to adjacent buildings.

[0013] The beneficial effects of the present invention are embodied in: The present invention divides the mechanical stereo garage structure into modules and submodules, so that the same garage unit submodules can be assembled and installed as a whole, thereby improving construction efficiency. Compared with the conventional single-frame installation, the number of construction hoists and high-altitude docking is reduced, which not only improves installation accuracy but also improves construction efficiency.

DETAILED DESCRIPTION

[0016] Taking the construction of a certain science and technology innovation center as an example, it consists of 12 steel columns arranged symmetrically from east to west. The cross-section of the steel columns is "□"-shaped, with a size of 300×300mm and a plate thickness of 12 to 25mm. There are 15 layers of steel beams between the columns, a total of 338 pieces, 380 inter-column supports, and the top elevation of the structure is +35.260m.

[0017] like Figures 1 to 5 As shown, the main structure 1 of the garage is a frame steel structure, in which each garage is arranged from bottom to top and connected by beams. Figures 1 to 5 As shown, the modular installation method of the mechanical stereo garage structure is further explained. The specific steps are as follows: Step 1: According to the characteristics of the garage main structure 1, select the garage main structure 1 to be partitioned within the range of the facade height, and the partitions are used as garage area modules 2, and each garage area module 2 is set at the same height.

[0018] The garage area modules 2 each include a garage unit submodule 21 , the height of which adapts to the hoisting design requirements; and the relatively arranged garage unit submodules 21 are spaced apart upwardly along the horizontal length of the garage unit submodule 21 .

[0019] The garage unit submodule 21 comprises two parallel garage columns 211, a garage beam 212 connecting the columns 211, a garage diagonal brace 213 between the upper and lower garage beams 212, and a garage pre-reserved joint 214 located on the columns 211 at the junction of the columns 211 and the beams 212. The beams 212 are spaced apart in the height direction of the columns 211, with the spacing adapted to the height of each floor in the garage. The diagonal braces 213 are arranged in a V-shaped or inverted V-shaped configuration, alternating in height. The two legs of the V-shaped or inverted V-shaped brace are located at the inner corner where the columns 211 and the beams 212 meet, with the apex located in the middle of the beam 212.

[0020] Step 2: Make an assembly frame 3 , make the garage unit submodule 21 on the assembly frame 3 , and then complete two relatively independent garage unit submodules 21 .

[0021] In this embodiment, the assembled tire frame 3 includes two tire frame main rods 31 arranged in parallel, a tire frame connecting rod 32 connected between the two tire frame main rods 31, and a tire frame stopper 33 arranged on the top of the tire frame main rods 31; the tire frame main rods 31 and the tire frame connecting rods 32 together 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] The tire frame main rod 31 is made of two 9m long H400×400×13×21 steel sections, and the tire frame connecting rod 32 is made of C14 channel steel.

[0023] The tire frame stopper 33 is an L-shaped member made of C14 channel steel. Its horizontal portion is fixedly connected to the top of the tire frame main bar 31. Two tire frame stops 33 are provided at each end of each tire frame main bar 31, with the two tire frame stops 33 positioned opposite each other. The distance between the vertical portions of the L-shaped member corresponds to the distance between the garage columns 211.

[0024] Step 3: Use a total station to accurately measure the endpoint shape of the garage unit submodule 21, use a spirit level and a steel ruler to check and adjust the flatness of the garage unit submodule 21, control the center misalignment deviation of the horizontal component, and re-measure the entire garage unit submodule 21 after it is formed as a whole. Reserve weld gaps at the node positions and control the welding shrinkage size. After the entire module unit is assembled and welded, re-measure it again.

[0025] Step 4: Hoist the two opposite garage unit submodules 21 and place them at the designed position of the garage main structure 1; use cables for temporary fixation and use lifting machinery to install the splicing connector 22 between the two garage unit submodules 21 to form a small frame.

[0026] The splicing connector 22 connects the garage reserved joints 214 of two opposite garage unit submodules 21 , and the splicing connector 22 includes a horizontal connecting rod and diagonal bracing rods arranged on the upper and lower adjacent horizontal connecting rods.

[0027] Step 5: The sub-modules 21 of the garage units in the same partition are installed in sequence to form small frames, and then connected through the connecting parts 23 to form the garage area module 2.

[0028] In this embodiment, the butt connector 23 is connected to the garage reserved joint 214 between adjacent small frames. The butt connector 23 is a straight rod. The material and style of the butt connector 23 are set in accordance with the garage beam 212; the butt connector 23 is set in sequence corresponding to each garage beam 212 in the height direction.

[0029] Step 6: The garage area modules 2 are constructed sequentially from bottom to top. After the adjacent garage area modules 2 are firmly connected and meet the design requirements, the next garage area module 2 is constructed until the overall construction of the garage main structure 1 is completed.

[0030] In addition, a garage bottom connecting member 4 is provided at the bottom of the garage main structure 1, and a garage top connecting member 5 is provided at the top; the garage bottom connecting member 4 and the garage top connecting member 5 are both rods, and are both fixedly connected to the adjacent buildings.

[0031] The present invention can reduce 35%-50% of high-altitude operations by assembling the area first and then the modules on the ground. At the same time, the assembly work can be carried out simultaneously with the lifting operation. In addition, the ground welding nodes are superior to high-altitude docking in terms of construction efficiency and quality control. At the same time, through the ground assembly of the module units, the installation accuracy of the center positioning axis of the steel beam can be better controlled on the tire frame.

[0032] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that a person skilled in the art can conceive within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
