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 p

Example Embodiment

[0028] Example 1: A BIM-based internal and external beam (or column), see figure 1 with figure 2 , Adopt thin-walled steel single beam and thin-walled steel single column, and set single active connecting piece and passive connecting structure between beam and column. See image 3 , Only a single active connector is provided at the end of the single beam 2, and only a hook hole 4 is provided in the middle of the single column 1. See Figure 4 , While the single active connector is provided at the end of the single beam 2, a hook hole 4 is provided in the middle of the single beam 2.

[0029] See Figure 5 with Image 6 As shown, the active connector includes a front wall, a rear wall, two side walls, and upper and lower walls, as well as a connecting flange 31 provided on the upper and lower walls and an n-shaped hook 33 provided on the front wall (hook support wall 34). In fact, the active connector in this embodiment is a single active connector formed by folding steel plates,...

Example Embodiment

[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 8-10 , The active connector is a C-shaped steel combined active connector formed by welding two pairs of buckled C-shaped steels. The inner side of the C-shaped steel of the two pairs of buckles matches the welded web at least at the end position, and the outer surface of the C-shaped steel of the two pairs of buckles Positioning grooves for punching or punching are provided; between each web and the groove-shaped steel plate or the two side plates of the groove-shaped connecting plate are provided with an outwardly opening relief groove; on the outside of the two pairs of buckled C-shaped steels are provided The cable tie positioning groove 51 and the clamping groove are arran...

Example Embodiment

[0037] Embodiment 3: On the basis of embodiment 1, the steel structure beam or column is changed into solid wood beam 2b, such as Picture 11 As shown, the active connector is sleeved on the end of the solid wood beam or column and fixed by a steel cable tie.

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...
