Method of constructing multi-story building structure

The present invention relates to a method for constructing a building structure, in particular to a method for quickly constructing a multi-story building structure.

The rapid construction of high-quality buildings has long been the goal pursued by the architecture and construction industry. Among many construction methods, the 預鑄 method has been successfully applied to various construction and construction projects because of its excellent quality, rapid construction safety, and economic and reasonable construction cost. The 預鑄 method of construction is based on the 預鑄 factory or the periphery of the construction site. It uses standardized operating procedures and modular molds to produce steel structures, such as steel cages, build templates and pour concrete, and quickly mass produce high precision and high quality uniformity Columns, beams, plates and other structural components. Subsequently, the finished structural components are assembled on the construction site through precise handling management and assembly operations. In this way, the workload on the construction site can be minimized, manpower and construction time can be reduced, and the construction period can be shortened. In addition, this construction method can also reduce or avoid scaffolding construction, greatly improving construction safety.

The conventional method of construction uses a layer-by-layer method to construct the structure. The floor structure of the lowest floor must be completed first, including all beams, columns, and floor slabs, and then the construction is carried out layer by layer. The construction speed is still There is room for improvement to further meet the needs of the industry. In view of this, the development of a structure that can quickly build multiple floors to further accelerate the construction speed is indeed a long-awaited by the industry.

Such as the method of claim 6, wherein the height of each floor between the beam-column structures is divided into a plurality of areas along a first direction, and at least one of the areas on the other floors above the lowest floor is selected The area is the hoisting area, which serves as the hoisting path of the slab structure, and the remaining area is the slab placement area, and the supporting components are pre-installed in the slab placement area to the beam structure located in the slab placement area , Used to support the floor slab structure. In the hoisting area, the beam structure of the beam-column structure is not pre-installed with supporting components. For example, in the method of claim 7, the step (e) includes: In the hoisting area, from the lowest floor, install the floor structure of each floor until the highest floor is completed; in the hoisting area, gradually from the lower floor To the higher floors, install supporting components on the beam structures of these beam-column structures, and install the slab structure until the highest floor is completed. Such as the method of claim 8, wherein the slab structure includes an upper layer and a lower layer, wherein the upper layer protrudes outwardly with a plurality of steel bars for overlapping, but does not exceed the edge of the lower layer of the slab structure. Such as the method of claim 1, wherein step (a) includes: arranging the pillars on the corners and sides of the unit area, wherein the beam-pillar structures include a first beam-pillar structure and a second beam-pillar structure The beam-column structure, at the height of each floor, the first beam-column structure is provided with roughly orthogonal beam structures on two adjacent sides of the column structure, and the second beam-column structure is opposite to the column structure Both sides are provided with substantially aligned beam structures, and step (c) includes: installing the first beam and column structure to the column at the corner of the unit area, and installing the second beam and column structure to the On the column on the side of the unit area.
