For giving full play to the advantage such as short, low-carbon environment-friendly of assembling cold-rolled forming section structure construction cycle, and guarantee that structure stress is reliable, anti-seismic performance is good, is necessary to invent a kind of novel joint and is applied to assembling cold-rolled forming section structure.To the research of beam column novel joint form with and in the application study of assembling cold-rolled forming section structure to the applying so that the development tool of whole steel work industry is of great significance of assembling cold-rolled forming section structure, be problem demanding prompt solution in scientific research and the engineering practice.
The utility model content
The purpose of this utility model is that bearing diagonal cold-rolled forming section assembled arthitecutral structure can not satisfy standardization, production industrialization, build assemblingization and the good requirement of load-carrying properties in the pin prior art, and proposes the bearing pin flange joint structure that a kind of assembling cold-rolled forming section structure connects.It is characterized in that, the column sleeve pipe is the two ends casing flange 2 of burn-oning about in the of 4, and up and down two chord members 8 of girder truss are welded on the column sleeve pipe 4, chord member 8 and the column sleeve pipe 4 junctions stiffening rib 7 of burn-oning, and at welding web member 9 between two chord members 8 up and down; Two column jeckets 10 pass through post bushing pipe 11 in the 4 interior grafting of column sleeve pipe up and down, and column jecket 10 is fastening with post flange 1 and casing flange 2 with being connected by bolt 12 of 4 of sleeve pipes, consists of thus bearing pin flange joint structure.
Described post flange is enclosed within on the column jecket and is welded and fixed, and the flange stiffener 6 of burn-oning in post flange 1 and column jecket 10 junctions
Described post flange is square square frame, and the overall structure of equidistant screw hole is arranged on four limits.
Described casing flange and post flange have same size and shape and structure, but are divided into 2 half or 4 half.
Described in up and down two column jeckets 10 of column sleeve pipe 4 interior grafting each welded post shrouding 3, post bushing pipe 11 two ends fixed leg bushing pipe shroudings 5, post bushing pipe 11 are placed between the post shrouding 3 of two column jeckets 10 up and down; The weight bearing power that holds for increasing column sleeve pipe 4.
The beneficial effects of the utility model are to have following characteristics because of bearing pin flange joint structure of the present invention:
1. the advantages such as easy construction, mounting or dismounting be convenient, and because the girder truss distortion drives the column jecket distortion by sleeve pipe, flange in the node of this kind type of attachment, column jecket is pegged graft in sleeve pipe, therefore under geological process, when casing flange and post flange bolt Joint failure, still can bear certain load, still have certain deformability and energy dissipation capacity, anti-earthquake ductility is better.
2. represent by the finite element method (fem) analysis result, the bearing pin flange joint structure that beam column connects is reasonable, and rigidity is larger, has larger bearing capacity and has more than needed, and node connects reliable, can satisfy the designing requirement of " rod member a little less than the strong node ".The assembling bearing diagonal cold-rolled forming section structure superstructure of using this kind node has enough bearing capacities and can satisfy the normal requirement of using.
Description of drawings
Fig. 1 is the floor map that the bearing pin flange joint is used in assembly unit.
Fig. 2 is the Flange Plane figure of bearing pin flange joint, and wherein A figure is the post flange, and B figure is casing flange.
Fig. 3 is the concrete constructional drawing of bearing pin flange joint.
The specific embodiment
The utility model proposes the bearing pin flange joint structure that a kind of assembling cold-rolled forming section structure connects.Be explained below in conjunction with accompanying drawing.
At Fig. 3 center pillar sleeve pipe two ends casing flange 2 of burn-oning about in the of 4, the top-bottom chord 8 of girder truss is welded on the column sleeve pipe 4, two chord members 8 and the column sleeve pipe 4 junctions stiffening rib 7 of burn-oning up and down, and at welding web member 9 between two chord members 8 up and down; The post flange is enclosed within on the column jecket and is welded and fixed, and the flange stiffener 6 of burn-oning in post flange 1 and column jecket 10 junctions; Each welded post shrouding 3 in two column jeckets 10 up and down, post bushing pipe 11 two ends fixed leg bushing pipe shroudings 5, described cut shaft flange with two column jeckets 10 up and down by post flange 1 in the 4 interior grafting of column sleeve pipe, post bushing pipe 11 is placed between the post shrouding 3 of two column jeckets 10 up and down, for increasing the weight bearing power that holds of column sleeve pipe 4; Be connected by bolt 12 post flange 1 and casing flange 2 is fastening between column jecket and column sleeve pipe, consist of thus bearing pin flange joint structure.
Splicing as shown in Figure 1 between floor mainboard structure and mainboard.
