Description

BIM-Based Beam or Column Inner Hanging and Outer Connection Structure

technical field

The invention relates to the technical field of beam or column connection of building structures, in particular to a BIM-based beam or column internal hanging and external connection structure.

Background technique

The connection design of the column and the beam of the building structure is a difficult and important point in the wall design. At present, there are various methods for the connection of the column and the beam of the building, such as: horizontal and vertical plug-in type, corner expansion and floating Code plug-in type, through-slot bolt type, two-way locking type, etc. The following problems generally exist: (1) The complex connection structure leads to high manufacturing costs and low on-site construction efficiency. When increasing the load capacity of beams and columns or beams and beams, it is necessary to set up anti-detachment structures and add additional fittings. (2) Poor positioning affects construction efficiency. When assembling beams and columns on site, it is usually a high-altitude operation, and poor positioning increases construction difficulty. (3) The stress strength is poor. In the various connection structures between beams and columns or beams and beams, there is usually only one connection constraint relationship. (4) The tightness of the butt joint is poor, and it needs to be supplemented by manpower to make it combined and then fixed, and it is easy to form a beam-to-column or beam-to-beam gap.

In the prior art, a solution of quick butt joint between the connecting piece and the thin-walled steel profile by tightening the steel strip is adopted. This scheme is suitable for short-term rapid assembly of thin-walled steel structure houses, with reasonable structural design and high strength under no-failure conditions. However, the above-mentioned patented technology has the problem of great difficulty in profile manufacturing during the implementation process, and cannot be well combined with existing profile forming machines, requiring special forming equipment and high cost. In this patented technology, the tubular or trough-shaped profile is placed on the outside of the connector, and then the hoop groove on the connector is used as the anti-falling fixing center, and the profile is forcibly compressed in the hoop groove with a hoop steel belt. However, in actual use, because there are steps and edges on the edges of the flanges on both sides of the hoop groove, and the thickness of the thin-walled steel profile is very thin, usually about 0.3mm, the thin-walled steel profile after being compressed and deformed by the hooped steel belt is easily damaged. After the damage, the strength of the profile will be significantly reduced, and even the entire profile will be broken, and the cavity formed after the damage cannot be treated with anti-corrosion. After the rainwater enters the damaged gap, the connection structure will be corroded.
