Embodiment 1

[0035] Embodiment 1, an assembled steel-wood composite node, such as figure 1 and 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 and 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-s...

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 assembly, such as Figure 12 As shown, the shown corner post connection assembly also includes a square solid wooden pile, two mutually perpendicular second square wooden beams ( 13 , 17 ) and two wooden bolts 26 . The adjacent two sides of the square solid wood pile are respectively provided with I-type chute 27, and the top of the I-type chute 27 on one side runs through the whole solid wood column, and the bottom of the I-type chute on the other side runs through the whole solid wood column. 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 arr...

Abstract

The invention relates to an assembled steel-wood composite node, which includes a square pipe column, a steel-wood composite beam and a beam-column connection assembly connecting the square pipe column and the steel-wood composite beam; the square pipe column includes a connecting corner column and a connecting side plate, The steel-wood composite beam includes an upper flange, a lower flange and a wooden web connecting the upper flange and the lower flange. The beam-column connection assembly includes a center column connection assembly and a corner column connection assembly. Through special structural design, On the premise of avoiding welding and bolting connections, the effective connection between beams and columns can be realized, and it has certain toughness and good seismic performance. Its components can be prefabricated in factories, with high component precision and on-site splicing. The construction period is effectively shortened; and the steel-wood composite structure is adopted, which improves the utilization rate of materials with different strengths. Through ingenious connection and cooperation, the combination of steel-wood structures can form an efficient and reasonable new structural form, which improves the richness of architectural expression. diversity.

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...
