Embodiment Construction

[0019] The present invention is further described below in conjunction with accompanying drawing:

[0020] see Figure 1 to Figure 5 , an assembled node connected by riveting, including a column 1, a beam 11, a beam end and a column end plate 2; the ends of the four beams 11 are fixedly provided with beam ends, and the ends of the four beams 11 are two The two are arranged opposite to each other to form a cross-shaped structure, and the ends of adjacent beams are fixedly connected; the column end plate 2 is arranged at the end of the column 1, and the two columns 1 with column end plates are respectively arranged above and below the cross-shaped structure, and Each column end plate 2 is fixedly connected to all beam ends on the cross structure.

[0021] The beam end includes the beam top plate 5, the beam upper cover plate 6, the beam lower cover plate 7, the stiffening rib 8 and the beam end side plate 9; the beam is an I-shaped steel beam, and the web plate at the end of th...

Abstract

The invention provides an assembled node employing rivet connection. The assembled node comprises stand columns, cross beams, beam end heads and stand column end plates; the end portions of the four cross beams are fixedly provided with the beam end heads, the end portions of the four cross beams are oppositely arranged to form a cross-shaped structure, and the adjacent beam end heads are fixedlyconnected; the stand column end plates are arranged at the ends of the stand columns, the two stand columns with the stand column end plates are respectively arranged on the upper side and the lower side of the cross-shaped structure, and each stand column end plate is fixedly connected with all the beam ends on the cross-shaped structure. According to the assembled node, by strengthening the columns in the junction region, the strength and rigidity of node parts are improved, and large damage to the columns at the node under the earthquake action is avoided. The structure is prefabricated ata factory, so that site welding and column connection are avoided, the welding quality is not high; and meanwhile, the situations that due to a large welding area, large residual deformation is easilygenerated, the stress performance of the node is affected, the node ductility is poor, and the construction speed and quality are affected are avoided.

Description

technical field [0001] The invention relates to the field of steel structures, in particular to an assembled node connected by riveting. Background technique [0002] In traditional beam-column joints, the columns at the joints are prone to greater damage under earthquake action. The upper and lower flanges of the beam-column and the web are connected to the column by on-site welding, and the welding quality is not high. Large residual deformation affects the mechanical performance of joints, poor ductility of joints and affects construction speed and quality, so it is not suitable for fabricated steel structures. In the case of bolted connection corrosion, the change in mechanical properties decreases greatly, which has requirements for the construction environment. Contents of the invention [0003] The object of the present invention is to provide an assembled node connected by blind riveting, so as to solve the above-mentioned problems. [0004] To achieve the above ...
