Problems solved by technology

At present, the development and deepening of such joints in the industry is still in the research stage, especially in the application of space roof truss engineering, where circular tubes, square tubes, H-shaped steel and other multi-section and multi-standard rods are combined in space to form a component system , and the planar distribution is wide, the number is large, the system is strong, and the layout is scattered. The meeting nodes cannot be pre-assembled on-site for factory stereotyped processing. On-site node assembly and welding, but the current conventional bar intersecting welded joints have a single form, and the joint stiffness load is too large, which does not meet the technical requirements for the spatial intersection of multi-section bars. , but the cost of engineering processing and installation is relatively high. Therefore, in terms of the balance between functional applicability and economic efficiency, it poses a severe technical challenge to the form of joint joints of small and medium-sized multi-section members in such space trusses.

Embodiment 1

[0033] Such as figure 1 The multi-section truss member intersection node structure shown includes the truss upper web member 1 and the horizontal circular pipe attachment rod 7, the vertical oblique circular pipe attachment rod 8 and the vertical oblique square pipe attachment rod 9, and the truss upper web member 1 The node 3 is welded below the node bar 3. The node bar 3 is a solid-belly rectangular node bar. The two ends of the node bar 3 are provided with head ribs 4. The side of the node bar 3 is provided with a longitudinal wing plate 2, and the wing plate 2 Adopt unilateral asymmetric distribution, the part of the wing plate 2 located in the node bar 3 is flush with the upper end of the node bar 3, and the part protruding from the node bar 3 above the wing plate 2 is welded and fixed with the truss upper web bar 1, The horizontal circular tube 7, the vertical oblique circular tube 8 and the vertical oblique square tube 9 meet under the node bar 3 and are fixedly connect...

Embodiment 2

[0035] The joint structure of multi-section truss members in Embodiment 2 is basically the same as that in Embodiment 1, the difference is that: image 3 As shown, the airfoil 2 adopts multi-plate asymmetric distribution, the airfoil 2 runs through the node bar 3, and two airfoils 2 are distributed on one side of the node bar 3, and the two airfoils 2 respectively pass through the connecting plate 6 and two I-beam beams 5 are welded and fixed.

[0036] The construction method of the multi-section truss member converging node structure described in the present invention comprises the following steps:

[0037] 1) Horizontal placement of node rods: the mid-span horizontal placement of node rods is carried out in advance, and the two ends of the node rods hang out of the confluence node;

[0038] 2) Fixing of the wing plate: Firstly, open the opening slit of the wing plate on the node bar, and set it as a V-shaped groove to reserve a weld bead, place the wing plate horizontally i...

Abstract

The invention relates to the field of building construction, in particular to a multi-section truss rod intersection node structure and a construction method thereof. The multi-section truss rod intersection node structure comprises a truss web rod and a plurality of lacing rods. A node rod is fixedly connected below the truss web rod. The node rod is a solid-web type rectangular node rod. End sealing rib plates are arranged at two ends of the node rod. A longitudinal wing plate is arranged on the lateral side of the node rod in a penetrating manner. The part, located in the node rod, of the wing plate is parallel with the upper end of the node rod. The wing plate is fixedly connected with the node rod and the truss web rod. The lacing rods are connected below the node rod in an intersection manner. The multi-section truss rod intersection node structure has the advantages that the solid-web type rectangular node rod with a closed section is added to the inner side of an intersection node, the intersection connection of rods of various specifications and various sections is achieved, the load-bearing load of a node rigid region is balanced, the rigidity distribution of various intersection rods is ensured, and the structure of a spatial truss intersection node is simplified.

Description

Technical field [0001] The present invention involves the construction of the construction construction field, and the structure of a truss exchange node is specifically involved in the structure and its construction methods. Background technique [0002] With the rapid development of the modernization of society today, large shopping malls and public construction facilities have risen. Among the large -scale and large -space framework systems, the steel truss lid has gradually become a solution to large span, ultra -high -net empty lighting topThe best choice of load -bearing structure.However, in the context of the industry's lean in recent years, in order to lighten the trussee structures as much as possible, in response to the technical requirements of various functional components, stress effects, etc., the design is to decompose the trusses system pole, and comprehensively rectangle, rectangular, and comprehensive rectangular, rectangular, and rectangular, rectangular, and ...
