Embodiment Construction

[0078] A high-strength concave-convex channel steel connection house, see figure 1 , including skeletons, walls and roofs, and doors and windows. The skeletons include columns, beams, bottom connectors, corner connectors, shear connectors, and stairs.

[0079] High-strength concave-convex groove square tube: see Figure 2-Figure 4 It includes four (or six) square tube 1a sides that are bent and enclosed by steel plates to form a rectangle, and each side of each square tube 1a is provided with a concave notch that is bent and formed, and inside each notch It is provided with a bent and formed internal slideway which is in the same direction as the notch and has a width greater than that of the notch.

[0080] The notch includes two sides connected to the sides of the rectangular tube 1a, and the internal slideway includes two sides connected together, a bottom surface, and two upper surfaces respectively connected to the two sides of the notch.

[0081] The two sides of the n...

Abstract

The invention discloses a high-strength concave-convex groove-shaped steel connected house, which includes a skeleton, a wall body, a roof, and doors and windows. It mainly involves square or round rectangular tubes for columns or beams, corner connectors at the intersection of high-strength concave-convex groove square or circular tubes, high-strength concave-convex groove shear connection structures, outer shoe connectors for columns or beams, columns or The inner shoe connector of the beam and the connection structure of the high-strength concave-convex groove square-rectangular tube. Fast and stable connection is realized by using the corner connectors, and the construction speed is fast and the effect is good. Among them, the high-strength concave-convex groove square rectangular tube or round rectangular tube connection structure has a concave notch formed by bending on its side, and a bend in the same direction as the notch and wider than the notch is provided inside the notch. Formed internal slideway, such a structural design can greatly increase the moment of inertia, thereby improving the bending and torsional strength of the square tube.

Description

technical field [0001] The invention mainly relates to the technical field of cold-formed steel structural profiles, in particular to a high-strength concave-convex groove steel connected house. Background technique [0002] Square steel and round steel pipe are both hollow and long strips of steel, which are the most frequently used pipe fittings in the engineering field. Square steel and round steel pipe not only have bending and torsional strength, but also are light in weight, so they are widely used in the manufacture of mechanical parts and engineering structures. Small-sized square steel and cylindrical tubes in the prior art are generally divided into hot-rolled seamless round tubes, cold-drawn seamless round tubes, extruded seamless round tubes, and welded round tubes. The cross-sectional shape of the round tubes is generally conventional In recent years, some circular tubes with other cross-sectional shapes have appeared, but their moment of inertia has not been g...
