Description

Technical Field

[0001] The present invention relates to the technical field of assembled steel structure trestle bridges, and more particularly to a roof connection structure of an assembled modular steel structure trestle bridge. Background Art

[0002] A trestle is an overhead bridge structure. In recent years, with the continuous improvement of enterprise production capacity, the increasing demand for output and raw materials, material transport trestles have gradually developed into larger ones. The trestles have gradually evolved through different structural forms before developing into the current steel structure trestles.

[0003] The first stage: brick-concrete trestles, which have now been completely eliminated; the second stage: reinforced concrete trestles, which have good integrity but complex structures, heavy weight, complicated construction, long project cycles, and excessively high total costs; the third stage: steel trestles, which are currently more commonly used both domestically and internationally and come in several forms: angle steel or other steel trusses, space grids, and steel tube trusses. Their roof systems are generally installed on-site, requiring constant construction and long periods of high-altitude work, resulting in poor safety. The fourth stage: prefabricated modular steel trestles, a new type of material handling trestles. The prefabricated trestles use steel structural supports. The trestles are composed of several box units connected by bolts and assembled on-site to form a conveyor corridor. Belt conveyors are laid in the conveyor corridor to form a transportation system. The traditional roof system installation method is to hoist the modular roof system onto the top of the trestles and connect them with bolts. This connection structure cannot adjust the connection position between the roof and the trestle. When there is an error in the position of the bolt holes machined on the box unit or the roof system, the position of the bolt holes cannot be changed during the installation of the roof. The only option is to adjust the position of the roof so that the bolt holes on the roof match the bolt holes on the box. Therefore, the installation of the box unit and the roof system will produce a large error. Summary of the Invention

[0004] In view of this, the present invention provides a roof connection structure of an assembled modular steel structure trestle, which can adjust the connection position between the roof and the trestle to reduce construction errors.
