Sliding mode construction method for subway vehicle depot beam plate concrete structure

Abstract

The invention provides a sliding mode construction method for a subway vehicle depot beam plate concrete structure. The sliding mode construction method comprises the following specific construction steps of concrete frame column constructing, steel bracket installing, main beam track installing, guide wheel and main beam installing, steel truss installing, steel plate laying, beam side formwork support installing, first construction section formwork support erecting, first construction section formwork installing, first construction section beam plate steel bar binding, first construction section beam plate concrete pouring, sliding mode platform moving, second construction section beam plate steel bar lifting and second construction section beam plate concrete pouring. According to the sliding mode construction method for the subway vehicle depot beam plate concrete structure, the construction cost can be reduced to a large extent, and the construction period can be shortened to a large extent; and due to the fact that the bottom of a frame body is isolated through thick steel plates, the common safety risks of insufficient stability of the frame body, falling from high places, object strike and the like in the high and large formwork construction process are effectively reduced.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a slip-form construction method for a beam-slab concrete structure in a subway depot Background technique [0002] With the rapid development of the national economy, the state's investment in social infrastructure is more and more inclined to improve and improve the field of national transportation, and a climax of subway construction has been set off across the country. The subway depot is the harbor for the subway to stay and overhaul. Its structural characteristics are mostly high storey height and large span. During the construction of the main structure, the supports are mostly supported by tall formwork. . How to ensure the construction period, quality and safety during the construction of tall formwork is an important and difficult point in the construction of the main structure of the subway depot. The support methods currently used mainly include steel p...

Problems solved by technology

However, there are still disadvantages such as large investment and high cost in the process of erecting the tall formwork support as a whole

[0009] To sum up, these three kinds of frames need to be constructed after the foundation earthwork is backfilled and compacted or the ground is hardened. The waiting time for the process is long, and the requirements for the bearing capacity and flatness of the foundation are high, and a large amount of turnover materials and manpower are required. , the rental fee and labor cost are high, and the economic benefit is low
