Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to the technical field of steel structure installation, and in particular to a sliding frame device for assembling a large-span steel structure arched roof. Background Art

[0002] ‌With the advancement of construction technology, large-span steel structures are increasingly used in large public buildings such as stadiums, exhibition halls, and airport terminals. These buildings usually need to cover a large area of column-free space, so higher requirements are placed on the span and bearing capacity of the steel structure.

[0003] Arched roof is a type of building structure characterized by an arched roof shape, which is usually used in large-span buildings. The design of the arched roof is inspired by the arched structure in nature, such as the arched structure of a bridge. This shape can effectively disperse the load and improve the stability and bearing capacity of the structure. The arched roof has become a common choice for large-span buildings due to its good mechanical properties and beautiful appearance. The arched structure can effectively disperse the load, reduce the use of materials and provide a larger internal space.

[0004] However, large-span arched roofs often face many challenges during construction, such as high altitude operation difficulty, heavy component weight, and high installation precision requirements. Traditional construction methods such as hoisting and segmented assembly usually require the installation of a large number of fixed assembly frames, which often have problems such as low construction efficiency, high cost, and many safety hazards.

[0005] To solve the above technical problems, a Chinese invention patent with the publication number CN203430063U discloses a slip assembly jig for installing the main truss of a long-span steel structure roof. It includes sleepers, tracks, traveling wheels, wheel frames, steel bottom frames, steel pipe jigs, and steel pipe connection frames. These sleepers are evenly distributed in three rows at intervals, and a set of three tracks are respectively laid on the sleepers in each row, with a total of three sets, that is, nine tracks laid. A steel bottom frame is erected on the three sets of tracks, and a total of nine sets of traveling wheels are correspondingly installed at the bottom of this steel bottom frame. Steel pipe sleeves are evenly welded and installed in a rectangular arrangement on the upper surfaces of the steel frames of the steel bottom frame. Equal-height steel pipes are respectively inserted into the steel pipe sleeves, and horizontal pipes, vertical pipes, or diagonal bracing pipes are evenly installed from bottom to top on the steel pipes on the same side of each steel frame to form a vertical steel pipe jig respectively. The upper parts of the steel pipe jigs are connected into an integral body by steel pipe connection frames respectively. The structure of the above invention device is simple. The jigs under one main truss can be connected into a whole, with good integrity. Sleepers are used under the basic tracks, and the force is evenly distributed. However, during the process of flowing water construction, the main body of the jig needs to be installed after the concrete of the lower floor reaches a certain strength, resulting in a long technical interval, which is not conducive to shortening the construction period. Secondly, the main body of the jig is entirely connected by steel pipes, and its self-strength has certain limitations, and the ability to bear vertical loads is average. And there is only one steel structure jig throughout the construction process. It can only be slid to the next main truss after the installation of the previous main truss is completed and installed in sequence. The installation efficiency is low. At the same time, the previous main truss may have local settlement displacement after unloading, which is not conducive to the accuracy of the overall roof steel structure system. Finally, a telescopic adjustment device is not adopted at the top, increasing the labor cost, and manual work at height will also bring safety hazards. Therefore, it is not conducive to the popularization and application of the above slip assembly jig for installing the main truss of a long-span steel structure roof in the field of building construction technology.

[0030] When the sliding jig device for assembling a large-span steel structure arched roof in this embodiment is used for steel structure installation operations, the following steps are specifically included: S1. Weld the support columns 1-3 to the main steel beams on the lower floor. The spacing depends on the column spacing of the lower floor. The positions of the support columns 1-3 need to be consistent with the direction of the support sliding rails 1-1. The elevation of the surface of the support columns 1-3 should be kept as flat as possible to ensure the horizontality of the support sliding rails 1-1 placed on them. S2. Fix the support beam 1-2 above the support columns 1-3. The length of the support beam 1-2 is the length covered by the main truss of the steel structure roof to be installed. S3. Install the support sliding rails 1-1 along the center line position at the top of the above-mentioned support beam 1-2. The length of the support sliding rails 1-1 is the length covered by the main truss of the steel structure roof to be installed. S4. Rigidly connect a traction mechanism platform 5-2 at the end of the steel structure roof truss installation direction of the support beam 1-2. Install a winch 5-1 above the traction mechanism platform 5-2, and wind a steel wire rope 5-3 around the drum of the winch 5-1; S5. Assemble the jacking support assembly 2 of the falsework, the main body 3 of the falsework and the adjustable assembly 4 at the top of the falsework on the ground. After the falsework is assembled, use a lifting device to hoist it onto the above-mentioned support slide rail 1-1, and the jacking support assembly 2 of the falsework needs to be temporarily fixed to the support beam 1-2; S6. According to the operation of S5, install 3 falseworks on the same support slide rail 1-1. Connect the falseworks with a falsework connecting beam 6-1. The 3 falseworks are connected into a whole. The steel wire rope 5-3 in S4 is connected to the lifting ring 3-4 on the side of the conversion platform 3-2 in the first falsework; S7. Start the winch 5-1 on the traction mechanism 5, and use the steel wire rope 5-3 to tow the falsework to directly below the main truss of the steel structure. In the direction from one end of the track to one end of the traction mechanism 5, the first falsework, the second falsework and the third falsework are numbered as falsework ①, falsework ② and falsework ③ respectively. Falsework ①, falsework ② and falsework ③ correspond to the 3rd main truss, the 2nd main truss and the 1st main truss; S8. Start the jack 2-3, i.e., the hydraulic jack, in the jacking support assembly 2 of the falsework to make the surface of the conversion platform 3-2 of the whole section of the falsework at the same horizontal plane; S9. After the verticality of the falsework is adjusted, drive the transmission gear 4-5 through the drive motor 4-3 in the adjustable assembly 4 at the top of the falsework to adjust the up and down movement of the rack 4-2. Then determine the position of the fulcrum by using a total station to make points. The two cooperate with each other to make the steel support 4-6 reach the specified position, and then pull the guy wire in the fixing mechanism 6; S10. After the whole device is in place, hoist the 1st, 2nd and 3rd main trusses of the steel structure. After the hoisting is completed, move the falsework ③ to support below the completed 3rd main truss, and move the falsework ② and falsework ① to below the 4th and 5th main trusses at the same time, and complete the above-mentioned in-place operation.
