Abstract

The invention provides a scaffold-free prefabricated frame structure beam column mounting method. The scaffold-free prefabricated frame structure beam column mounting method comprises the steps of prefabricating and mounting a prefabricated column, a main beam and a secondary beams, wherein the upper end of the prefabricated column mounted in place is connected with a beam supporting device during mounting, the main beam is placed on stirrups of a main bracket in the beam supporting device, the main beam is located in a main beam anti-torsion mechanism at the same time, the secondary beam is placed on stirrups of a secondary bracket of the beam supporting device, and the secondary beam is located in a secondary beam anti-torsion mechanism at the same time; the end face of the main beam, the end face of the secondary beam and the top face of the prefabricated column serve as formworks to define a mold cavity, concrete is poured, and the main beam, the secondary beam and the prefabricated column are connected into a whole. The scaffold-free prefabricated frame structure beam column mounting method can be combined with factory prefabrication, is convenient to operate, is economical and reasonable, and is favorable for accelerating the construction period, controlling the construction cost and promoting the industrial development of buildings.

Description

technical field

[0001] The invention relates to the field of construction, in particular to a method for installing beams and columns of a prefabricated frame structure free of scaffolding. Background technique

[0002] Prefabricated concrete structures can meet the needs of housing industrialization and construction industrialization and conform to the concept of green and low carbon. In recent years, they have received strong support from the Chinese government and have broad development prospects. Prefabricated frame structure is one of the most commonly used structural forms in prefabricated buildings, and prefabricated beam-column connection technology is the key technology of prefabricated frame structure. At present, the construction of prefabricated beam-column joints usually requires the erection of steel pipe fastener load-bearing frames, which can only be dismantled after the construction of beam-column joints and prefabricated slabs reaches the design strength. ...

Examples

Embodiment Construction

[0045] The scaffolding-free prefabricated frame structure beam column installation method provided by the present invention includes:

[0046] Prefabrication and installation steps of the prefabricated column 100, the main beam 200 and the secondary beam 300. When the prefabricated column is prefabricated, two layers of connecting through holes 103 are prefabricated between the first opposite surface 101 near the upper end, and the first opposite surface is the side of the prefabricated column 100 on the same side as the main beam 200 and its opposite surface; every layer of connecting through holes 103 has two, and the diameter of the connecting through holes of the upper floor is less than the diameter of the connecting through holes of the lower floor, so that both the connection strength with the beam supporting device is guaranteed and the structural strength of itself is ensured. The connecting operation of the support device is more convenient. When the main girder 200...
