[0029] Reference Figure 1-7 As shown, this embodiment provides a telescopic and slidable prefabricated tire frame, comprising:

[0030] The base frame 1 includes a plurality of groups of H-shaped steels, and roller grooves 101 are spaced apart at the bottom of the H-shaped steels. A plurality of roller groups 102 are installed in the roller grooves 101. Limiting grooves 105 are arranged on the two side walls of the roller grooves 101.

The top of the rolling portion 1052 is vertically bent to the right and extends to form a receiving portion 1051. The roller group 102 includes a connecting rod 103 and a plurality of rollers rotatably connected to the connecting rod 103. The parts of the two ends of the connecting rod 103 that pass through the limiting grooves 105 are provided with threaded portions, and the threaded portions are matched with locking nuts 104.

[0031] Furthermore, the height of the lowest end of the rolling portion 1052 from the ground is smaller than the radius of the roller, and the height of the receiving portion 1051 from the ground is larger than the radius of the roller.

[0032] By setting a roller groove 101 at the bottom of the base frame 1, and then setting limiting grooves 105 on the two side walls of the roller groove 101, the roller group 102 located in the roller groove 101 can be stored and unfolded along the limiting groove 105, and then the connecting rod 103 is fixed with the locking nut 104, so that the prefabricated tire frame can realize the function of temporary transportation and facilitate its own movement.

[0033] Furthermore, a plurality of groups of reserved installation grooves are arranged at intervals in the middle of the base frame 1, and vertically installed vertical shafts 4 are arranged in the installation grooves, and both ends of the vertical shaft 4 are fixedly installed at the top and bottom of the reserved installation grooves.

[0034] Furthermore, a width adjustment assembly is provided between each two adjacent groups of H-shaped steels, and the width adjustment assembly includes a plurality of connecting rods 2. The two connecting rods include two groups of connecting rods 2 arranged in parallel in the vertical direction. The parallel connecting rods 2 all pass through the reserved mounting grooves and are movably connected to the two adjacent groups of H-shaped steels through vertical shafts 4. The plurality of connecting rods 2 are cross-arranged, and the intersections of the plurality of connecting rods 2 are movably connected through pins 3. The plurality of connecting rods 2 have a diamond structure as a whole.

[0035] By rotating and setting two hinged connecting rods between two adjacent groups of base frames 1, the spacing between the base frames 1 can be adjusted, and the overall width of the prefabricated tire frame can be adjusted, so that the prefabricated tire frame can better adjust the tire frame coverage area according to project needs to meet the needs of different projects.

[0036] Secondly, the connecting rods 2 are connected to the base frame 1 through the vertical shaft 4, and then the two groups of connecting rods 2 are movably connected through the pin shaft 3. The connection method is simple, which makes the assembly of the prefabricated tire frame simple and easy to operate, making it easier for assemblers to get started, thus solving the problem of high assembly requirements for traditional ordinary tire frames.

[0037] Furthermore, at least four groups of locking nuts 401 are provided on the vertical shaft 4, and the end of the connecting rod 2 close to the base frame 1 is inserted between two groups of the locking nuts 401, and gaskets 402 are placed at both ends of the two groups of locking nuts 401. The connecting rod 2 is fixed and movable by cooperating with the locking nuts 401 located on the upper part of the connecting rod 2 and the gaskets 402.

[0038] Furthermore, at least four groups of rotating nuts 301 are arranged on the pin shaft 3, one end of the connecting rod 2 away from the base frame 1 is inserted between two groups of the rotating nuts 301, and one end of another group of connecting rods 2 away from the base frame 1 is inserted between the other two groups of rotating nuts 301, and limiting gaskets 303 are placed at both ends of each two groups of rotating nuts 301, and the limiting gaskets 303 cooperate with the rotating nuts 301 to fix and move the two groups of vertically parallel connecting rods 2.

[0039] The construction steps of this utility model are:

[0040] 1. The prefabricated tire frame is transported from the factory and hoisted to the assembly site by a truck crane or tower crane at one time. If the truck crane or tower crane can hoist the entire assembled tire frame to the site, you can choose to hoist the tire frame as a whole; if the lifting capacity of the truck crane or tower crane is insufficient, the tire frame components can be hoisted to the assembly site in batches.

[0041] 2. The roller group 102, H-shaped steel and the connecting rod 2 connected to the vertical axis 4 have been installed together in the factory, and the rollers can be removed and increased or decreased as needed. The base frame 1 is hoisted about 40cm above the assembly site, and the connecting rod 103 of the roller group 102 at the bottom of the base frame 1 is pushed from the storage part 1051 to the rolling part 1052 according to the shape of the limit groove 105, and the roller will extend out of the bottom surface of the H-shaped steel. After all the roller groups 102 are extended, the base frame 1 is slowly placed on the assembly site, and then the H-shaped steel can be pushed to the specified position by manpower.

[0042] 3. After each set of base frames 1 is in place, the connection work of the connecting rods 2 can be carried out. The number of connecting rods 2 on the vertical shaft 4 in the base frame 1 remains unchanged, and then the pins 3 are inserted into the two sets of parallel connecting rods 2, and then the four rotating nuts 401 in the middle are screwed in turn, two by two, and then the washers 402 are placed at both ends of the rotating nuts 401, and the steel ring washers 302 are used to separate the upper and lower closely adjacent connecting rods 2, and finally the washers 402 and the double rotating nuts 401 are used to seal the upper and lower ends of the pins 3, leaving 1-2 threads exposed.

[0043] 4. When the positions of all the base frames 1 are determined and the connecting rods 2 are all connected, two people will work symmetrically from the middle of a group of base frames 1 to both ends at the same time, and push the connecting rod 103 of the roller group 102 at the bottom of the base frame 1 from the rolling part 1052 to the storage part 1051 according to the shape of the limiting groove 105. The roller will leave the ground, and the base frame 1 can be placed stably on the assembly work surface. Operate the remaining base frames 1 in sequence.

[0044] 5. In order to make the tire frame and the assembly site form a stable whole, use expansion bolts to connect the bottom of each base frame 1 of the tire frame to the site, and then place steel gaskets between the expansion bolts and the bottom of the base frame 1.
