Problems solved by technology
[0003] At present, the connection between the steel members of the steel structure is usually bolted or welded. Both connection methods require a certain amount of operating space. If the space is small, the installation is difficult and time-consuming; each of the box-type modular buildings Modular units are usually composed of four columns and eight beams, so there are eight intermediate connection nodes of modular units in the central area of the modular building, which are connected to eight columns and sixteen beams at the same time. Lack of operating space, the traditional connection node form cannot realize the connection without damaging the surrounding components; and the traditional connection node cannot transmit vertical force and horizontal force, and the overall structure has potential safety hazards

Embodiment Construction
[0024] The present invention will be further described below in conjunction with accompanying drawing:
[0025] like figure 1 As shown, the present invention includes a modular unit consisting of a unit column 1 and a unit beam 2 . There are four unit columns 1, and eight unit beams 2. like figure 2 As shown, a notch is provided at the end of the modular unit, and a corner piece is provided in the notch, and the notch and the corner piece are fixedly connected by welding. The eight corners on each modular unit are provided with corner fittings. A group of eight modular units is assembled into a box structure. Connecting pieces are arranged between the corner fittings on the modular unit, and the corner fittings are fixedly connected with the connecting pieces. An operation hole 8 is provided on the unit column 1 near the corner piece. like Figure 4 , Figure 5 and Image 6 As shown, the corner fitting includes a bottom plate 4 , a corner fitting enclosure 11 , a cov...

The invention discloses a tenon-type connecting device of a modularized unit intermediate column node, The invention relates to the technical field of building engineering, comprising a modular unit,wherein the modular unit is composed of a unit column and a unit beam; the end point of the modular unit is provided with a notch; the notch is provided with corner pieces; eight modular units are assembled into a group of box structures; and the corner pieces on the modular unit are provided with connecting pieces; and the corner pieces are fixedly connected with the connecting pieces. The invention has the advantages of small construction space, convenient installation and high construction speed. The connecting device does not destroy the modular unit and its surrounding components, ensuresthe integrity of the modular unit, and is suitable for connecting nodes in the middle area of the modular unit. Moreover, the connecting device can ensure the horizontal and vertical load transmission in the connecting area of the modular unit, and ensure the safety and reliability of the whole structure.
Description
technical field [0001] The invention relates to the technical field of construction engineering, in particular to a bayonet type connection device for intermediate column nodes of modular units. Background technique [0002] The modular prefabricated building is to divide the whole building into several box-type modular units, and prefabricate and install the modular unit floors, ceilings, and walls in the factory. Stack and connect together to form a complete building. The main unit of the modular building is usually produced in a factory assembly line and the interior of the unit is usually complete. Only hoisting and simple assembly are required on site, which greatly reduces the workload and construction time on site, and has excellent construction quality, saving manpower and material resources, and green construction. Environmental protection and many other advantages. [0003] At present, the connection between the steel members of the steel structure is usually bol...
