Abstract
The invention relates to an intersecting joint, in particular to a butterfly-shaped intersecting joint in a spatial structure, which is used in a large-span spatial pipe truss structure in the field of construction steel structures. The butterfly-shaped intersecting joint in the spatial structure comprises a main pipe and branch pipes, wherein two pairs of branch pipes are inserted into the main pipe; the two pairs of branch pipes incline and extend outwards; the main pipe and the two pairs of branch pipes form a butterfly shape; each branch pipe comprises a connecting board, a cone body and a web member; the connecting board is fixed with the main pipe; the cone body is arranged between the web member and the connecting board; and two side walls of the main pipe are provided with chord connecting positions. The butterfly-shaped intersecting joint in the spatial structure has simple structure and reasonable stress, reduces construction difficulty, and improves security.
Description
Technical field
The present invention 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 present invention solves 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 invention 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; 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; The junction plate of described arm 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; 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.
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, the described person in charge and arm are the rigidity part.
As preferably, the angle of the described junction plate and the person in charge's outward-dipping shape is 0 degree～90 degree.
Therefore, butterfly-shaped intersecting joint in spatial structure provided by the invention, simple in structure, stressed reasonable, reduce difficulty of construction, improve safety.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a sectional structure schematic diagram of the present invention;

The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, technical scheme of the present invention 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 6 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, the person in charge 1 and arm 2 are the rigidity part, described junction plate 3 is 0 degree～90 degree with the angle of outward-dipping shape of the person in charge 1, and chord member connects the two ends connection chord member 9 of position.
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.
