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.

Embodiment 1

[0028] Example 1: A BIM-based beam (or column) with internal and external connections, see figure 1 and figure 2 , using thin-walled steel single beams and thin-walled steel single columns, and setting a single active connector and passive connection structure between the beams and columns. see image 3 , only a single active connector is provided at the end of the single beam 2, and only the hooking hole 4 is provided at the middle of the single column 1. see Figure 4 , while the single-type active connector is provided at the end of the single beam 2, a hooking hole 4 is provided at the middle of the single beam 2.

[0029] see Figure 5 and Figure 6 As shown, the active connector includes a front wall, a rear wall, two side walls, upper and lower walls, and connecting flanges 31 arranged on the upper and lower walls and n-shaped hooks 33 arranged on the front wall (hook support wall 34 ). In fact, the active connector described in this embodiment is a single active...

Embodiment 2

[0034] Embodiment 2: Based on Embodiment 1, the beams, columns and active connectors are respectively modified to form a C-shaped steel composite beam 2a, a C-shaped steel composite column 1a, a C-shaped steel composite active connector 3a and a C-shaped steel composite passive connector 5. see Figure 8-Figure 10 , the active connector is a C-shaped steel combined active connector welded by two paired C-shaped steels. The inner sides of the C-shaped steels of the two paired buckles match the welded web at least at the end position, and the outer surfaces of the C-shaped steels of the two paired buckles There are positioning grooves for stamping or punching; there are relief grooves that open outward between each web plate and the two side plates of the channel-shaped steel plate or the channel-shaped connecting plate; Tie positioning groove 51, the draw-in groove is arranged at the position corresponding to the web.

Embodiment 3

[0037] Embodiment 3: On the basis of Embodiment 1, change the steel structure beam or column into solid wood beam 2b, such as Figure 11 As shown, the active connectors are fitted over the ends of solid wood beams or columns and secured with steel ties.

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...
