BIM-based (building information modeling based) internal cladding and external connecting beam or column

Abstract

The invention discloses a BIM-based (building information modeling based) internal cladding and external connecting beam or column. An active connector is fixed to an end of the beam or column in a sleeving manner, and / or a passive connecting structure is arranged on the side wall of the beam or column; the front end face of an active connector body is provided with an n-shaped hook, and a connecting flange is disposed at an edge of the front end face; the passive connecting structure is provided with a cladding hole in the sidewall of the beam or column or passive connector, and the cladding hole matches with the n-shaped hook. The hook is in a wedged structure or the cladding hole is in a wedged structure so that the beam and column are mounted by opposite inserting, the beam and the column extrude each other for tight attachment after sliding down under the gravitational action, and field connection is very quick without manual centralizing or added accessories for work. The beam and column positioned and compressed are connected through a flange and can be fixedly connected by using tapping screws or traversing bolts or by welding. Two supporting modes hook supporting and flange supporting are present, improving connection strength of the beam and column. The beam or column is simple in structure, very quick to construct in situ and suitable for popularization and implementation.

Description

technical field [0001] The invention relates to the technical field of building structure beam or column connection, in particular to a BIM-based inner-hanging and outer-connecting beam or column. Background technique [0002] The connection design of the column and the beam of the architectural structure house is a difficult and important point in the wall design. At present, there are many kinds of connection methods for the column and the beam of the building structure, such as: horizontal and vertical plug-in type, corner expansion floating type, corner 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 eff...

AI Technical Summary

Problems solved by technology

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 of existing 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 manpower is needed to make it combined and then fixed, and it is easy to form a beam-to-column or beam-to-beam gap

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 for anti-corrosion. After rainwater enters the damaged gap, the connection structure will be corroded.
