Embodiment 1

[0035] Embodiment 1, an assembled steel-wood composite node, such as figure 1 with Figure 10 As shown, it includes a square pipe column 1, a steel-wood composite beam 2, and a beam-column connection assembly 3 connecting the square pipe column 1 and the steel-wood composite beam 2;

[0036] The square column 1 includes a connecting corner post 4 and a connecting side plate 7, such as figure 2 with image 3As shown, the square column 1 is composed of four connecting corner columns 4 and four connecting side panels 7 to form a hollow column structure, wherein the connecting corner columns 4 are column steel with high corrosion resistance, and the connecting side panels 7 are wooden boards . Compared with the pure steel structure, the steel-wood composite column has a higher bearing capacity per unit mass, which can reduce the weight of the overall structure to a certain extent and improve the overall life span. The cross-section of the connecting corner post 4 is a 90° arc...

Embodiment 2

[0047] The difference between Embodiment 2 and Embodiment 1 is that the center column beam-column connection assembly is replaced by the corner post connection assembly. For the corner post connection assembly, such as Figure 11 with 14 As shown, it adopts a similar design principle to the central column connection component, such as Figure 12 As shown, the shown corner post connection assembly also includes a square solid wooden post, two mutually perpendicular second square wooden beams ( 13 , 17 ) and two wooden bolts 26 . Respectively set I type chute 27 on both sides adjacent to the square solid wood column, the top of the I type chute 27 on one side runs through the whole solid wood column, the bottom of the I type chute on the other side runs through the whole solid wood column, the second The square wooden beam 13 and 17 is provided with the I type slide 29 that matches with the I type chute, and the I type slide 29 on the second square wooden beam 13 is arranged al...

Abstract

The invention relates to a fabricated steel-wood composite joint. The fabricated steel-wood composite joint comprises a square pipe column, a steel-wood composite beam and a beam-column connecting assembly connecting the square pipe column with the steel-wood composite beam; the square pipe column comprises a connecting corner column and a connecting side plate, the steel-wood composite beam comprises an upper flange, a lower flange and a wood web plate connecting the upper flange with the lower flange, and the beam-column connecting assembly comprises a central column connecting assembly anda corner column connecting assembly. Through special structural design, under the premise of welding and bolting connection, the beam and the column are effectively connected, certain toughness and good seismic performance are achieved, components of the fabricated steel-wood composite joint can be prefabricated in a factory, the component precision is high, on-site splicing is achieved, construction is easy and convenient, the processes are reduced, and the construction cycle is effectively shortened; and by adopting a steel-wood composite structure, the utilization rate of materials of different strength is increased, through ingenious connection and cooperation, the efficient and reasonable structure new form is achieved through combination and synergy of the steel-wood structure, and the rich diversity of architectural performance is improved.

Description

technical field [0001] The invention belongs to the technical field of connection of building structures, and in particular relates to an assembled steel-wood composite node. Background technique [0002] With the advent of the era of building industrialization, prefabricated structures have gradually become an important way for future building development. Compared with traditional welding and bolt connections, the installation of prefabricated structures only requires simple assembly training, which can ensure the construction quality to the greatest extent. Steel structure buildings have the advantages of high lightness, good plastic toughness, light weight, and good seismic performance. However, the steel structure is heat-resistant, not fire-resistant, easy to rust, poor corrosion resistance, and there are many quality problems in the welding of structural steel. Wood structure buildings have high durability, high earthquake resistance, convenient materials, fast const...
