Problems solved by technology

[0004] However, due to the influence of welding process and environmental factors, the quality of the weld between the outer ring plate and the steel pipe column is difficult to guarantee, and the joint area is prone to initial defects due to the influence of welding stress
Through test simulation and finite element analysis, it is found that this type of joint is very easy to tear the weld when it is subjected to large loads and earthquakes, thereby affecting the bearing capacity of the joint and the overall seismic capacity

Embodiment 1

[0052] Such as Figure 1-3 , 22, a fully assembled steel structure connection assembly according to the present invention includes 2 square steel pipe columns 1, an outer ring plate assembly and several connecting members, and the upper and lower square steel pipe columns are along the steel pipe at the splicing end. The column wall is provided with corresponding concave-convex grooves 14, so that the adjacent joints present regular concave-convex and broken-line shapes. When splicing, the protrusion (depression) of the lower section of the square steel pipe is inserted into the depression (protrusion) of the upper section of the steel pipe, making the connection of the two sections of square steel pipe more precise. The square steel pipe column is formed by plugging the upper and lower square steel pipes through the splicing auxiliary device 6, and is fixed by bolting with the riser assembly of the outer ring plate at the same time. The splicing auxiliary device is a pair of...

Embodiment 2

[0060] Such as figure 1 , 12 , 13, the difference from Embodiment 1 is that the horizontal veneer is structural form B, including three connecting plates, the connecting plates and the horizontal plate are in the shape of a bucket, and the connecting plates on both sides and the middle connecting plate are respectively perpendicular to the horizontal The connecting plates on both sides are bent outward relative to the middle connecting plate, and respectively form the same angle with the middle connecting plate. Connect the connecting plates on both sides of one single board with the connecting plates of the other two single boards with bolts, which can be assembled in the vertical direction, and ensure that the horizontal boards of each horizontal single board assembly remain horizontal and at the same height on the plane.

[0061] All the other technical features are the same as in Embodiment 1.

Embodiment 3

[0063] Such as image 3 As shown, the upper and lower surfaces of the outer plate are provided with protruding prisms 10, and the cross-section of the prisms is isosceles trapezoidal. The corresponding position on the bottom surface of the horizontal plate is provided with a chute 11 corresponding to the shape of the prisms. The chute is an isosceles trapezoidal chute.

[0064] All the other technical features are the same as in Embodiment 1.

Abstract

The invention relates to a fully fabricated steel structure connecting assembly and a mounting method, and belongs to the technical field of building structural components. The fully fabricated steelstructure connecting assembly comprises two square steel pipe columns, outer ring plate assemblies and connecting members. An interlocking broken-line-form concave-convex groove is formed in the jointof the two square steel pipe columns. The outer ring plate assemblies comprise horizontal single plate assemblies and vertical plate assemblies. A plurality of bolt holes are formed in a square steelpipe column wall, inner plates, outer plates, horizontal plates and connecting plates, the square steel pipe column and the outer ring plate assembly are connected by bolts, and the outer ring plateassemblies are connected to each another by bolts and sliding groove devices. The fully fabricated steel structure connecting assembly prevents the occurrence of local stress concentration phenomenon,improves the stress performance of joints, and enhances the rigidity of the joints and components in the horizontal direction, so that the stress distribution in the joint region is relatively uniform, the rigidity is large, the bearing capacity is high, and initial defects caused by welding and possible weld joint tear damage are avoided.

Description

technical field [0001] The invention relates to a fully assembled steel structure connection assembly and an installation method, belonging to the technical field of building structural components. Background technique [0002] The steel pipe column makes up for the defect of the large difference in rigidity in the two symmetrical planes of the H-shaped steel column, which can effectively avoid the excessive deformation of the structure due to the large load in the direction of the weak axis. With the gradual improvement of my country's steel processing and manufacturing technology, steel pipe columns are more and more used in steel structures, and the combination of steel pipe columns and I-shaped steel beam joints is becoming more and more widely used because of its unique superior performance. use. [0003] In the frame structure, the beam-column connection plays an important role in the overall seismic performance of the steel structure, and the choice of its form has a ...
