Problems solved by technology

[0003] In order to ensure its own bearing capacity, integrated houses need to adopt solid steel beams and columns, which are heavy, expensive, and limited in building height. Although the steel frame structure has good bearing capacity, it cannot be used directly.
At present, most of the connection methods between integrated houses and steel frame structures are welding, and there are few existing patents on the joints between steel frame beams and integrated house skeleton beams. Most of the patents are only for the connection of integrated house Research on the structure optimization and material selection of the house itself or the optimization and research on the beam-column connection nodes of the fully assembled steel frame system

Embodiment 1

[0036] A connection method between frame beams and frame beams of integrated houses and a method for determining connection nodes, including frame beams 1, frame beams 2, plug-in components 3 and supporting bolts 4; the plug-in components 3 include paired mating U-shaped steel plate 5 and L-shaped steel plate 6; L-shaped steel plate 5 consists of a horizontal steel plate 5.1 and a vertical steel plate 5.2 vertically arranged at one end of the horizontal steel plate 5.1; U-shaped steel plate 6 consists of a horizontal steel plate 6.1 and two The vertical steel plates 6.2 and 6.3 vertically arranged at both ends of the horizontal steel plates are composed of steel plates connected by welding with 7 welds.

[0037] In the following, combined with the attached drawings, the length of the integrated house is designed to be 12m, the width is 8m, and the height is 3.3m. The steel frame structure has a column spacing of 6m in the depth direction and a column spacing of 8m in the bay di...

Embodiment 2

[0039] The method for determining the connection node between the frame beam and the integrated building skeleton beam includes the following steps:

[0040] Step 1: Calculate the bolt spacing according to formulas (1) to (4) to ensure that the structure has good integrity under horizontal earthquake loads:

[0041] G=[H+1.2(L+Q)]lh (1)

[0042] f Ek = α max G (2)

[0043]

[0044]

[0045]In the formula: G—representative value of gravity load; H—dead load; L—live load, Q—dynamic load; l—length of frame beam; h—width of frame beam; F Ek —Standard value of seismic action at structure level; α max ——maximum value of horizontal seismic influence coefficient; d——diameter of bolt shank; n——number of bolts; f v b - bolt shear strength; d b — bolt spacing; t — beam flange thickness;

[0046] According to the structural requirements, when the bolt spacing d calculated by formulas (1) to (4) b greater than 15d 0 , the bolt spacing is taken as 15d 0 , where d 0 is the ...

Abstract

The invention belongs to the field of civil engineering, and relates to a method for determining a connecting mode and a connecting joint of a frame beam and an integrated house framework beam. The connecting mode comprises the frame beam, the framework beam, an inserted connection assembly and matched bolts. The inserted connection assembly comprises U-shaped steel plate elements and L-shaped steel plate elements matched in pairs. The integrated house framework beam and the frame beam are connected through the high-strength bolts. The distance of the bolts is obtained through numerical analysis, and the size of the inserted connection assembly is determined through analysis of an ABAQUS finite element model. The connecting joint is simple in structure and uniform in modulus; precise positioning can be performed on an integrated house and the frame beam through the inserted connection assembly; only bolt connection is needed during field assembly, and construction is easy; the integrated house and a steel frame can be conveniently installed and detached, the structure of the steel frame is not damaged, the frame is utilized multiple times, the resource saving and the moving with the house are realized, and the high-assembly type building mode is embodied; and the integrated house is applied to multi-storey dwellings and even mid-rise and high-rise buildings.

Description

technical field [0001] The invention belongs to the field of civil engineering, and relates to a connection mode between a frame beam and an integrated building skeleton beam and a method for determining a connection node. Background technique [0002] Integrated housing is a modular design, factory production, mobile, and reusable building products. It is mostly used in temporary offices and dormitories on construction sites, field exploration, and construction houses for field operations. At this stage, integrated housing The connection between them is mainly in the form of welding. On-site welding is difficult and the quality is uncontrollable, and the seismic performance of the welded connection is far inferior to that of the bolted connection. In order to ensure the safety of the structure, the existing prefabricated houses often use solid steel as the skeleton columns and skeleton beams, which are heavy, high cost, and inconvenient to transport, so that prefabricated h...
