Embodiment Construction

[0062] See Figure 1-5 As shown, a modular roadbed box includes four roadbed box steel beams 1, bottom plate, top plate, stiffening rib plate 2, and end sealing plate 3, which are arranged longitudinally and horizontally at parallel intervals.

[0063] The subgrade box steel girder is H-shaped steel, each road subgrade box steel girder includes an upper flange plate 11, a web 12 and a lower flange plate 13, and the subgrade box steel girder includes two side beams 1a and two middle beams 1b.

[0064] The lower side of the top plate is fully welded to the upper side of the upper flange plate 11.

[0065] The upper side of the bottom plate is fully welded to the lower side of the lower flange plate 13.

[0066] The upper connecting plate 4 is butted in the gap between the upper flange plates 11 of two adjacent road foundation box steel beams.

[0067] A lower connecting plate 5 is butted in the gap between the lower flange plates 13 of two adjacent road foundation box steel beams.

Abstract

Provided are a modular subgrade box, a steel trestle platform structure and a construction method thereof. The modular subgrade box comprises a subgrade box steel beam, a bottom plate, a top plate, astiffening rib plate and an end seal plate. The steel trestle platform structure comprises a modular subgrade box, a foundation pit structure and a supporting structure of each stage. The steel trestle platform structure comprises a steel beam, a bottom plate, a top plate, a stiffening rib plate and an end seal plate. The construction method is divided into stages. The invention breaks through thetransportation lifeline inside and outside the building, ensures the on-site material transportation, becomes the prerequisite for the smooth construction of the structure on schedule, and verifies the rationality of the temporary construction steel trestle road. Modular components are used to greatly reduce the workload of the site, the temporary construction steel trestle road is set up, and the transportation channel of the structure is opened. Modular components can be reused, practical maneuverability and reference value is greater, in line with the promotion and application of architectural assembly in China, for the future similar projects to provide new construction ideas, with the value of promotion and application.

Description

Technical field [0001] The invention belongs to a temporary auxiliary construction structure, in particular to a modular roadbed box and its temporary steel plank structure and construction method. Background technique [0002] In modern architecture, architects often construct various sinking corridor structures, but designing the sinking corridor structure around the main structure will cause many difficulties in site construction. [0003] 1. The sinking ring corridor cannot be constructed at the same time as the main structure. At the same time, the transportation vehicles are restricted by the ring corridor and cannot approach the main structure, resulting in a narrow construction site on the side of the ring corridor and no transportation channel can be formed. [0004] 2. Affected by the sinking ring corridor, only the use of the tower crane in the middle of the structure cannot meet all the needs of steel structure unloading. The steel column and steel beam have a large cros...
