[0002] With the development of my country's construction industry, large steel truss / frame aerial bridge structures are becoming more and more common in landmark buildings. During construction, bridge structures are mostly assembled on the ground and lifted as a whole. During ground assembly, many factors often restrict the assembly construction, such as: (1) The bearing capacity of the garage roof within the ground assembly range of the bridge structure is insufficient and cannot bear the load of the existing bridge structure; (2) There are multiple elevations of the garage roof within the ground assembly range of the bridge structure; (3) If a full-height support system is used during ground assembly, there will be more restrictive factors: ① The top structure of the multi-story structure cannot ensure the stability of the scattered parts during assembly; ② When the single-story height is high, the welding and installation workers on the full-height support frame cannot operate; ③ The lifting vehicle cannot move in the full-height support system; ④ Positioning during installation and controlling the steel structure to prevent deformation during welding construction, the full-height support system also poses a huge obstacle to the installation of the bridge structure; ⑤ Some types of full-height support systems cannot meet the load requirements, and the rental and installation costs that meet the requirements are high.

Optionally, the lower adjustment rod includes two lower rod bodies and a connecting tube, one end of the two lower rod bodies is respectively threadedly installed in the two ends of the connecting tube, and the other ends of the two lower rod bodies extend out of the connecting tube.

[0022] There are multiple standard sections 2. Each standard section 2 is combined vertically to form a support frame. The four corners of the lower part of the support frame are respectively installed on the upper part of the lower adjustment rods of the four bases 1. The standard section 2 can be a construction elevator standard section. The construction elevator standard section can be extended to be used as a tower crane standard section.

[0023] There are four supports 4. The lower parts of the four supports 4 are respectively installed at the four corners of the upper part of the support frame. The lower part of each support 4 has an upright upper adjustment rod. The upper adjustment rod can be telescopic in the vertical direction. Optionally, the upper adjustment rod includes two upper rod bodies and a connecting tube, one end of the two upper rod bodies is respectively threadedly installed in the two ends of the connecting tube, and the other ends of the two upper rod bodies extend out of the connecting tube. The lower parts of the upper adjustment rods of the four supports 4 are respectively installed at the four corners of the upper part of the support frame. The upper part of each support 4 has a bracket opening upward.

[0024] There are two support columns 3, and both ends of each support column 3 are respectively installed inside the brackets of two adjacent brackets 4. The support column 3 has a slot opening downward. The support column 3 is a channel steel.

[0025] The combined standard tire frame also includes a support rod, a fixing block and a storage rack.

[0026] There are two supporting rods, which respectively penetrate the slots of the two supporting columns, and both ends of the supporting rods extend a certain distance outside the slots of the supporting columns.

[0027] There are two fixing blocks, which are respectively arranged on the two supporting rods and are respectively clamped on the first ends of the slots of the two supporting columns.

[0028] The storage rack is fixed on the upper part of the two supporting rods and is arranged at the second ends of the slots of the two supporting columns. The storage rack is used for arranging the construction parts. The storage rack has a storage slot opening upward.

[0029] The combined standard tire frame also includes pulleys and conveying ropes.

[0030] The pulley is mounted on the side of the storage rack.

[0031] The conveying rope is wound around the pulley, and the conveying rope is used to convey the construction parts.

[0032] An embodiment of the present invention provides a construction method using the above-mentioned combined standard tire frame, comprising the following steps:

[0033] (1) Install the base 1 and the standard section 2.

[0034] (2) According to the installation height of the component, select standard sections 2 to form a support frame.

[0035] (3) Install the support 4 on the support frame.

[0036] (4) The support column 3 is installed on the support 4 to obtain a combined standard tire frame.

[0037] (5) Use a combination of standard tire frame support components.

[0038] Before using the combined standard tire frame to support the components, the bearing capacity and stability of the combined standard tire frame shall be verified according to the material and bearing capacity value of standard section 2. If the overall stability of the combined standard tire frame is insufficient after the load is applied, the combined standard tire frame shall be reinforced with angle steel or steel pipe.

[0039] When using a combined standard tire frame, if the bearing capacity of the underlying foundation is insufficient, use the top-down method for point-to-point reinforcement.

[0040] When the combined standard tire frame support structure is used, there is a gap between two adjacent combined standard tire frames, and the gap is used for construction equipment to pass through.

[0041] When the combined standard tire frame is used to support the cross-shaped member, two combined standard tire frames are respectively supported at two sides of the vertical extension structure of the cross-shaped member.

[0042] The combined standard tire frame of the present invention solves the problems of the construction site environment and various restrictive factors in the construction when the existing large-scale steel truss / frame aerial bridge structure is assembled on the ground. The combined standard tire frame of the present invention is easy to operate and use when erected, and all components can be reused. The combined standard tire frame of the present invention has a high bearing capacity and overcomes many shortcomings of traditional full-height scaffolding. The height of the tire frame can also be adjusted by selecting different standard sections 2 according to the height of the structure, and can also be fine-tuned by using the support 4 and the base 1. When the combined standard tire frame of the present invention is used for steel structure installation, its bearing capacity, stability, and adjustable performance play its greatest advantages over other supporting structures. The greatest advantage of the combined standard tire frame of the present invention over other full-height support systems is that it can greatly save the lower space of the construction area, so that the operation of construction machinery and equipment such as lifting vehicles is not affected during the installation and welding of steel structures, and effectively speeds up the construction speed, improves work efficiency, and greatly saves the installation period of steel structures. The combined standard tire frame of the present invention can also be used for the construction of high-support formwork, bridges, etc.
