Problems solved by technology

[0003] The existing installation methods of prefabricated concrete frame structure buildings are generally prefabricated column installation, scaffolding support system installation, prefabricated main beam installation, prefabricated secondary beam installation, prefabricated laminated slab installation, cast-in-place reinforced concrete construction, scaffolding support system removal, etc. Operation, in which the installation and dismantling of the scaffolding support system requires more manpower and material resources and a longer time, failing to give full play to the advantages of the prefabricated construction method; in addition, for some buildings with higher floors, it is more difficult to build the scaffolding support system , high construction cost

Embodiment 1

[0048] This implementation provides a support-free installation method for prefabricated concrete frame buildings, and its application to large public buildings, such as libraries, includes the following steps:

[0049] S1. Use BIM to model the prefabricated components and connecting tooling, and obtain the installation plan of the prefabricated components and connecting tooling; the prefabricated components include: prefabricated columns 11, prefabricated main beams 12, prefabricated secondary beams 13 and prefabricated composite panels 14; the connecting tools include : Beam-column connection node 21, primary and secondary beam connection node 22 and beam-slab connection node 23.

[0050] Specifically, in step S1, the following steps are included:

[0051] S11, modeling according to the actual shape, weight and size of the prefabricated component 1 and the connecting tool 2;

[0052]S12. When the prefabricated component 1 and the connecting tool 2 do not collide during the ...

Embodiment 2

[0078] In recent years, with the development of urban subway rail transit, closely following the pace of construction of the subway network, the comprehensive development of resources such as the above-mentioned properties, underground space, and depots along the subway has become a development zone for the comprehensive utilization of urban subway rails in various places. A new development model to come. The development and operation of superstructure properties along the subway, underground space, and depot superstructure properties are the specific implementation platforms for the development strategy of "subway + property" and also a new growth point for benefits.

[0079] Taking a depot project as an example, the comprehensive development of the superstructure property of the depot has a greater impact on the construction difficulty and construction period compared with the previous construction of the depot, especially the construction of the superstructure property of th...

Abstract

The invention provides a support-free mounting method of a fabricated concrete frame building. The support-free mounting method comprises the following steps of modeling prefabricated parts and connecting tools by adopting BIM to obtain a mounting scheme of the prefabricated parts and the connecting tools, wherein the prefabricated parts comprise prefabricated columns, prefabricated main beams, prefabricated secondary beams and prefabricated laminated slabs, and the connecting tools comprise beam and column connecting joints, primary and secondary beam connecting joints and beam and plate connecting joints; installing the prefabricated columns, installing the beam and column connecting joints on the prefabricated columns, and placing the prefabricated main beams on the beam and column connecting joints; installing the main and secondary beam connecting joints on the prefabricated main beams and the prefabricated secondary beams, and connecting the prefabricated main beams with the prefabricated secondary beams through the main and secondary beam connecting joints; installing the beam and plate connecting joints on the prefabricated main beams and the prefabricated secondary beams,and placing the prefabricated laminated slabs on the beam and plate connecting joints; conducting cast-in-place construction; and dismounting the connecting tools. By the adoption of the method, a traditional scaffold installation system can be omitted, and the advantages of a fabricated building are brought into full play.

Description

technical field [0001] The invention belongs to the technical field of prefabricated buildings, and in particular relates to a support-free installation method for prefabricated concrete frame buildings. Background technique [0002] Prefabricated concrete frame structure buildings mainly use prefabricated columns, prefabricated main beams, prefabricated secondary beams, prefabricated laminated panels and other prefabricated components, which are produced in a factory and transported to the construction site for installation and construction; prefabricated concrete frame structure buildings are characterized by their Structural features meet the needs of large public buildings in terms of function and performance, and meet the national requirements for advocating sustainable development and green environmental protection. [0003] The existing installation methods of prefabricated concrete frame structure buildings are generally prefabricated column installation, scaffolding...
