Abstract
The utility model discloses an eccentric connecting inner sleeve and outer sleeve tubular node for a circular pipe and a box beam, which comprises a circular pipe and a main box beam. The circular pipe and the main box beam are arranged eccentrically; the tubular node is characterized in that the tubular node comprises outer sleeves and inner sleeves; the outer sleeves are symmetrically welded on two lateral web plates outside the main box beam, and the other ends thereof are respectively inserted into one part of the circular pipe, and welded and fixed with the circular pipe; the external diameter of the circular pipe is slightly smaller than the internal diameter of the outer sleeves; and the inner sleeves are welded between the two lateral web plates inside the main box beam. The connecting node has good structural performance under the condition of satisfying the requirements of specifications and the shape and the functions of buildings. The successful research of the eccentric connecting node for the circular pipe and the box beam plays a positive role in the development of a space structure in the civil industry of China and makes up the defects.
Description
Technical field
The utility model relates to a kind of node connecting structure of structural steelwork, the pipe that is specifically related to structure design in a kind of structural steelwork is connected internal and external casing formula node with the off-centre of box-girder, relate to particularly that pipe is connected internal and external casing formula node in a kind of large span, the large tracts of land deformed steel roof structure engineering with the off-centre of box-girder.
Background technology
Along with the development of national economic development, the development of city infrastructure, people are to improving constantly of requiring of cityscape and to the fixedly continuous variation of article external form requirement, the body of building also will change thereupon.Because large span, large-area profile iron structural system of roof that architectural image brings have also brought challenge for the node type of attachment of member.The domestic existing connection joints of steel structure is at present: the tubular joint that section steel beam is connected with section steel beam connected node, tube and tube, plate node, bolted spherical node, welded spherical node etc.And pipe is connected the domestic research precedent of still not having in this respect with the off-centre of box-girder: though the domestic tubular joint that has tube and tube to connect is two-way quadrature.
The utility model content
The purpose of this utility model is to provide a kind of pipe to be connected internal and external casing formula node with the off-centre of box-girder, to satisfy code requirement, architectural image, making and construction needs, guarantees building up of deformed steel roof structure simultaneously.
The technical scheme of the utility model technical solution problem is as follows:
A kind of pipe is connected internal and external casing formula node with the off-centre of box-girder, comprise pipe and box girder, described pipe and box girder are eccentric to be provided with, it is characterized in that, also comprise outer tube and inner sleeve, described outer tube is symmetrically welded outside the box girder on two coxostermums, and the other end of outer tube is insertion portion pipe and fixing with the pipe welding respectively, the pipe external diameter is more smaller than outer tube internal diameter, and described inner sleeve is welded between interior two coxostermums of box girder.Inner sleeve plays the stiffening rib effect.
Further, by 4 at a distance of 1/4 circular arc and be parallel to the slot weld of pipe axis and a circle fillet weld continuous sequence of outer tube end links together pipe and outer tube.
In sum, the disclosed connected node of the utility model adopts the eccentric position setting, by theoretical calculation analysis and experimental study, and takes construction measure, thereby under the situation that satisfies standard and architectural image, functional requirement, reached good structural performance.Described connected node bearing capacity can satisfy the seismic design requirement of the weak member of strong node; The energy dissipation ability and the ductility of node are better.The research success of the eccentric connected node of pipe and box-girder is played positive impetus to the development of China's building industry space structures, and is remedied deficiency in this respect.
Description of drawings
Fig. 1 is the appearance structure schematic diagram of the eccentric connected node of the utility model pipe and box-girder.
Fig. 2 is an A-A schematic cross-section among Fig. 1.
Fig. 3 is a B-B schematic cross-section among Fig. 2.
The specific embodiment
With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.
As shown in Figure 1 and Figure 2, the utility model pipe is connected internal and external casing formula node with the off-centre of box-girder, comprise pipe 2 and box girder 1, outer tube 3 and inner sleeve 4, described pipe 2 and box girder 1 eccentric the setting, described outer tube 3 is symmetrically welded outside box girder 1 on two coxostermums, the other end of outer tube 3 is insertion portion pipe 2 and fixing with pipe 2 welding respectively, and described inner sleeve 4 is welded between box girder 1 interior two coxostermums.
As shown in Figure 3, by 4 at a distance of 1/4 circular arc and be parallel to the slot weld 5 of pipe axis and a circle fillet weld 6 continuous sequences of outer tube end link together pipe 2 and outer tube 3.
The form of connected node should be determined according to the loading characteristic of actual engineering and structure.And connected node should be strengthened construction measure, guarantees designing requirement.The utility model can reach good structural performance under the situation that satisfies standard and architectural image, functional requirement.
