Description

Trestle for construction Technical Field The utility model relates to the field of underground engineering building construction, in particular to a trestle for construction. Background With the large-scale development of urban underground space development and utilization, deep and large foundation pit engineering faces the double challenges of difficult earthwork outward transportation and lack of material storage sites around the foundation pit. To solve these problems, it is currently common practice to provide trestle at the first support of the foundation pit. However, the traditional foundation pit trestle adopts a reinforced concrete structure, and has the defects of difficult line fixation and low construction efficiency, large difficulty in excavating soil below the trestle, incapability of being immediately put into use after the structure is completed, long repair period after damage and serious influence on construction progress. In addition, heavy construction machinery for trestle traffic needs to consume a large amount of materials such as cushion layers, supports, templates, steel bars, concrete and the like, has huge overall volume, is only used for the construction stage, and needs to be manually broken in the later stage to generate a large amount of solid wastes. Disclosure of utility model The present utility model has been made to solve the above problems, and an object of the present utility model is to provide a construction bridge. The utility model realizes the above purpose through the following technical scheme: The utility model provides a landing stage for construction, includes landing stage bearing reinforced concrete frame structure and decking, landing stage bearing reinforced concrete frame structure includes landing stage post, landing stage longeron, landing stage crossbeam, the decking is formed by steel member combination, the decking simply supported be fixed in on the landing stage crossbeam. Preferably, the trestle longitudinal beam and the trestle cross beam are of reinforced concrete structures, the trestle longitudinal beam is parallel to the long side of the bridge deck, the trestle cross beam is perpendicular to the long side of the bridge deck, and the trestle longitudinal beam and the trestle cross beam are connected with trestle columns through bolts. Preferably, the bridge deck is formed by welding and combining steel members, the steel members comprise an upper anti-slip panel, a lower hot-rolled steel plate, surrounding sealing plates and internal lattice ribs, all welding seams are fully welded, welding legs are more than or equal to 6mm, and the bridge deck adopts a modularized design. Preferably, the anti-skid panel is provided with crisscross anti-skid strips and four hoisting holes. Preferably, the depth of the anti-slip strip is more than or equal to 5mm. Preferably, rubber pads are required to be fully paved between the trestle cross beam and the bridge deck bottom plate, noise is reduced, and sliding of the bridge deck in the lateral direction is prevented. Preferably, limiting angle steel is arranged at the intersection position of the trestle longitudinal beam and the edge of the long side of the bridge deck to limit the transverse displacement of the bridge deck, and the limiting angle steel is welded and fixed on an embedded part above the trestle longitudinal beam.
