Problems solved by technology

[0003] Prefabricated buildings can gradually break through the limitations of the traditional housing construction process, and at the same time provide effective guarantees for the construction quality, safety and stability of construction projects through advanced technical means. However, the existing prefabricated buildings, especially in relatively At the high position, since all the parts are not completely prefabricated, at present, only some prefabrication is more, so for some prefabrication, it is necessary to build the formwork frame and pour the formwork at a higher position, which greatly prolongs the construction period

Embodiment Construction

[0037] Attached to the following Figure 1-5 This application will be described in further detail.

[0038] In a first aspect, an embodiment of the present application discloses a large-span prefabricated frame structure without support.

[0039] refer to figure 1 , a large-span prefabricated frame structure without support, including pillars 1 formed on the ground. The pillars 1 can be formed by prefabrication or cast-in-place. In this embodiment, the pillars 1 include prefabricated pillars. The cement cap 10 casted on the ground, the lower column 11 and the upper column 12, the lower column 11 and the upper column 12 are all prefabricated columns, and the lower column 11 is pre-fixed on the upper surface of the cap 10 , the bottom end of the lower column 11 and the protruding steel bars on the upper surface of the platform 10 are staggered and welded to each other. At the same time, C60 mortar is poured between the lower column 11 and the platform 10, and the pouring thick...

Abstract

The invention relates to the technical field of underground engineering construction, and discloses a large-span prefabricated frame structure support-free structure and an installation construction method.The large-span prefabricated frame structure support-free structure comprises two supporting columns formed on the ground and a prefabricated column cap fixed to the upper portions of the supporting columns, and the prefabricated column cap comprises a column head and an extending beam integrally formed on the side wall of the column head; a prefabricated beam is arranged between the two supporting columns, the prefabricated beam is in lap joint with the two opposite extending beams, a top plate is laid on the upper sides of the prefabricated beam and the extending beams, and a laminated layer is laid on the upper side of the top plate. A large number of temporary supports and formworks do not need to be erected, the construction efficiency is improved, and the installation precision is high. And the method has the advantages of high mechanization and industrialization degree, safety and environmental protection.

Description

technical field [0001] The present application relates to the technical field of underground engineering construction, and in particular, to a large-span prefabricated frame structure without support and a construction method. Background technique [0002] Prefabricated building refers to the transfer of a large number of on-site operations in the traditional construction method to the factory, and the construction components and accessories such as floor slabs, wall panels, stairs, balconies, etc. The connection method is a building assembled and installed on site. [0003] Prefabricated buildings can gradually break the limitations of the traditional house construction process, and at the same time can provide effective guarantee for the construction quality, safety and stability of construction projects through advanced technical means, but the existing prefabricated buildings, especially in the more At the high position, since all the components are not completely prefa...
