Embodiment Construction

[0017] Reinforced concrete building of the present invention reverse method construction technique, comprises the following steps:

[0018] 1. According to the design and specification requirements, carry out foundation, foundation and independent column foundation construction;

[0019] 2. According to the design and specification requirements, the left and right supporting concrete columns and the middle supporting concrete columns of the steel roof truss shall be constructed, and the height of the left and right supporting concrete columns and the middle supporting concrete columns shall reach the design elevation;

[0020] 3. Use the area between the left supporting concrete column and the middle supporting concrete column, and the area between the right supporting concrete column and the middle supporting concrete column as the hoisting channel for hoisting steel roof trusses, and hoist each steel roof truss to the left and right Connect and fix on the supporting concrete...

Abstract

The invention discloses a reinforced concrete building topdown method construction process, comprising the steps as follows: 1: the foundation, foundation and independent pile foundation construction is carried out; 2: a left supporting concrete column, a right supporting concrete column and a middle supporting concrete column of steel frame are established; 3: the areas between the left supporting concrete column and the middle supporting concrete column and areas between the right supporting concrete column and the middle supporting concrete column are used as hoisting passages of hoisting steel frame; each steel frame is hoisted onto the left supporting concrete column, the right supporting concrete column and the middle supporting concrete column; 4: all steel frames are hoisted on the left supporting concrete column, the right supporting concrete column and the middle supporting concrete column; after the connection and fixing operation, all steel frames are used as the roof of the reinforced concrete building; 5: in the roof, the indoor concrete frame structure is constructed. The method of the invention firstly constructs the side frame and the middle frame column structure, subsequently carries out the hoisting of the steel frame, and constructs the reinforced concrete structure in the clean area after the roof surface has no water, thus saving the construction period,reducing the cost, ensuring the safety hoisting, overcoming the effect of weather and ensuring the construction period and the construction quality.

Description

technical field [0001] The invention relates to a construction technology of a reinforced concrete building, in particular to a reverse construction technology of a reinforced concrete building for building a microelectronic industrial factory building. Background technique [0002] The microelectronics industrial factory building is an industrial factory building for the production of electronic chips. The foundation of the main factory building adopts a composite foundation foundation of independent column foundation, strip foundation and raft foundation; the upper structure is a reinforced concrete frame shear wall structure, and the roof is a steel truss roof. The floors are 3, 4, and 5 floors, generally not more than 30 meters high. The main factory building is a super-long and super-wide seamless structure. There is a clean room in the factory. The cleanliness of the clean room is 100,000, that is, the number of 1μm particles in each cubic meter of air does not exceed ...
