Beam column connecting structure of modular steel structure building

Abstract

The invention discloses a beam-column connecting structure of a modular steel structure building and a manufacturing method, the connecting structure is composed of a beam-column joint connecting piece and a beam-column module unit, the beam-column joint connecting piece comprises a bearing plate, the bearing plate is connected with a positioning steel plate with a cross-shaped cross section, and is provided with a cylindrical steel member; the positioning steel plate is connected with a T-shaped limiting steel plate; the beam column module unit is composed of a frame column and a frame beam, the frame column is a square tube steel structural member, a notch is formed in the middle of the end of the frame column, the frame beam is H-shaped steel, and a hole matched with the columnar steel structural member is formed in a flange of the frame beam; the notches of the frame columns are arranged on the limiting steel plates in a sleeved mode, the holes of the frame beams are arranged on the cylindrical steel members in a sleeved mode, and therefore one beam-column connecting joint can be connected with eight module units, namely the beam-column connecting structure of eight columns and sixteen beams is achieved. The method has the advantages of being high in assembling speed and environmentally friendly, can adapt to module assembling of various forms after being intercepted, and is high in applicability.

Description

technical field [0001] The invention relates to the field of modular steel structure buildings, in particular to a beam-column connection structure of a modular steel structure building. Background technique [0002] Nowadays, most civil buildings use cast-in-place reinforced concrete buildings. This kind of structure is self-heavy, has a long on-site construction period, high labor costs, and brings pollution, noise and other problems to the surrounding environment. Building industrialization is an inevitable choice for the development of my country's construction industry. . Modular building is an advanced stage of the development of building industrialization. Traditional houses are divided into rooms. The modular units are prefabricated in factories, and then transported to the site for connection to form a complete building. Modular building has the advantages of green environmental protection and efficient construction. It is an emerging building model with great devel...

Problems solved by technology

[0004] The design of joints is a key link in the construction of modular buildings. Due to the lack of construction space, existing modular steel structure joints are difficult to apply to central column joints. Only the design scheme of parallel arrangement of modules can be adopted, which greatly affects the design of modular steel structures. process floor plan flexibility, so it is necessary to propose a joint form that can be applied to the center column joint
