Abstract
The utility model relates to a tubular joint, in particular to a space structural butterfly-shaped cast steel tubular joint, which is used for a large-span space pipe truss in the field of building steel structures. The cast steel tubular joint comprises a main tube and branch tubes, two pairs of branch tubes are inserted on the main tube and extend obliquely outwards, the main tube and the two pairs of branch tubes form the shape of a butterfly, each branch tube comprises a connecting plate, a truncated cone and a web member, the connecting plate is fixed with the main tube, the truncated cone is arranged between the web member and the connecting plate, and chord member connecting sites are arranged on two side walls of the main tube. The cast steel tubular joint is simple in structure, reasonable in stress, lower in construction difficulty and higher in safety.
Description
Technical field
The utility model is a kind of tubular joint, particularly a kind of butterfly-shaped intersecting joint in spatial structure that is used for the large span space pipe trussed construction in construction steel structure field.
Background technology
Large span space pipe trussed construction is weighed the important symbol of building science technical level often in the prior art, also is the symbol of a development of civilization degree.In recent decades, because the development of large span space pipe trussed construction is very fast, in case history, also obtained utilization very widely, often the node between steel pipe runs through, and adopts directly welding, causes the overlapping welding of intersection, steel pipe passes through the generation location eccentricity mutually simultaneously, and the safety of whole node is low.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, provides a kind of connection simple, has the butterfly-shaped intersecting joint in spatial structure that supports arm.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of butterfly-shaped intersecting joint in spatial structure, comprise and being responsible for and arm, be plugged with two pairs of arms on the described person in charge, stretch on described two pairs of outward-dipping edges of arm, the person in charge is butterfly-like with two pairs of arms, and described arm comprises junction plate, Rotary-table and web member, and the described junction plate and the person in charge fix, be provided with Rotary-table between web member and the junction plate, the person in charge's two side is provided with chord member and connects the position.Adopted butterfly-shaped intersecting joint in spatial structure, comprehensively measuring and calculating by whole engineering, reduced about 20% than general large span space pipe trussed construction intersection fusion length, and avoided node place steel duct node to strengthen operation, make the easier for installation of whole engineering, economic benefit has obtained maximized embodiment.Along with the birth of these novel building structure nodes, the steel structure node architectural image is more elegant in appearance, and butterfly-shaped intersecting joint provides reasonable precondition also for the later stage preservative treatment of building structure.
As preferably, inwardly along flexible little formation stiffening rib, stiffening rib is positioned at the interposition of being responsible for inwall to the tube wall at described person in charge two ends gradually; Described arm junction plate is skewed and is fixedly connected with the person in charge, and described Rotary-table is the wedge shape Rotary-table, and the tapered end and the junction plate of Rotary-table fix, and the end that Rotary-table is connected with web member is provided with fixing lug boss.
As preferably, the diameter of described Rotary-table and the equal diameters of web member, described Rotary-table and web member are fixedly connected by weld layer.
As preferably, the angle of the described junction plate and the person in charge's outward-dipping shape is 0 degree～90 degree.
As preferably, the described person in charge and arm are the rigidity part.
Therefore, the butterfly-shaped intersecting joint in spatial structure that the utility model provides, simple in structure, stressed reasonable, reduce difficulty of construction, improve safety.

The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: as Fig. 1, Fig. 2 and shown in Figure 3, a kind of butterfly-shaped intersecting joint in spatial structure, comprise the person in charge 1 and arm 2, the tube wall of being responsible for 1 two ends is gradually inwardly along flexible little formation stiffening rib 7, stiffening rib 7 is positioned at the interposition of being responsible for 1 inwall, be plugged with two pairs of arms 2 on the described person in charge 1, stretch on described two pairs of arms 2 outward-dipping edges, be responsible for 1 and two pair of arm 2 and be butterfly-like, described arm 2 comprises junction plate 3, Rotary-table 4 and web member 5, described junction plate 3 fixes with the person in charge 1, be provided with Rotary-table 4 between web member 5 and the junction plate 3, the person in charge 1 two side is provided with chord member and connects position 6, the junction plate 3 of arm 2 is skewed and is fixedly connected with the person in charge 1, described Rotary-table 4 is the wedge shape Rotary-table, the tapered end of Rotary-table 4 and junction plate 3 fix, the end that Rotary-table 4 is connected with web member 5 is provided with fixing lug boss 8, the equal diameters of the diameter of Rotary-table 4 and web member 5, described Rotary-table 4 and web member 5 are fixedly connected by weld layer, junction plate 3 is 0 degree～90 degree with the angle of outward-dipping shape of the person in charge 1, the person in charge 1 and arm 2 are the rigidity part, and the two ends that chord member connects the position connect chord member 9.
Adopt butterfly-shaped intersecting joint in spatial structure, can be simpler, the node that carries out between steel pipe passes through mutually accurately, effectively prevent the adverse effect of the overlapping welding of on-the-spot intersection, improve the weld seam grade that node passes through the position mutually, and can prevent the location eccentricity that steel pipe passes through mutually, the whole node position is played the effect that improves its degree of safety reliability.
