Abstract
The utility model discloses a three-dimensional K-type tubular joint of a space steel tube truss. The three-dimensional K-type tubular joint of the space steel tube truss comprises a main tube, a middle plane inner branch tube, a first plane inner branch tube and a second plane inner branch tube. The main tube is respectively connected with the middle plane inner branch tube, the first plane inner branch tube and the second plane inner branch tube so that K shapes in three planes can be formed. The three-dimensional K-type tubular joint further comprises a tubular joint board, the tubular joint board is arranged in the middle plane and arranged on the connection portion of the middle plane inner branch tube and the main tube, and the tubular joint board and the middle plane inner branch tube are connected with the main tube. The axes of the main tube, the middle plane inner branch tube, the first plane inner branch tube and the second plane inner branch tube are jointed on one point on the tubular joint board, and therefore the joint bearing force satisfies the requirement for structural design.
Description
Technical field
The utility model relates to spatial steel tube-truss, novel joint form when particularly arm passes through weldering mutually with supervisor in three Different Plane.
Background technology
Spatial steel tube-truss structure is because it is neat from heavy and light, appearance rule, can not establish the advantages such as furred ceiling, and the application in long span building is increasingly extensive.Shockproof requirements based on structure stress and " strong node ", it is the key content in Truss Design that steel pipe truss passes through weldering node mutually, wherein K type tubular joint is the most general a kind of.In China < < Code for design of steel structures > >, KK type design of node in K type node in monoplane and two planes is had to clear and definite regulation, and require each plane K type node hidden seam welded to weld; Three-dimensional K type tubular joint design in three Different Plane is not related to.It is more that three-dimensional K type Nodes intersects rod member, and the general first assembled rear welding of node construction, cannot accomplish that each hidden weld seam welds, and therefore, prior art can not guarantee that ultimate bearing capacity of joints meets Structural Design Requirement.
Summary of the invention
Technical problem to be solved in the utility model is: overcome prior art defect, design a kind of spatial steel tube-truss three-dimensional K type tubular joint, in node, supervisor is K type node with the connected node of the interior arm of three Different Plane.
The problem that the utility model is the above-mentioned proposition of solution is adopted solution to be: a kind of spatial steel tube-truss three-dimensional K type tubular joint, it comprises in supervisor, mid-plane in arm, the first plane arm in arm, the second plane, described supervisor respectively with mid-plane in arm, the first plane in arm, the second plane arm form the K type in three planes; Described spatial steel tube-truss three-dimensional K type tubular joint also comprises perforation gusset plate, connect the junction that gusset plate is arranged in mid-plane and is arranged on the interior arm of mid-plane and supervisor, connect gusset plate and is connected with supervisor with arm in mid-plane, in supervisor, mid-plane, in arm, the first plane, the axis of arm, the interior arm of the second plane is all intersected in a bit on perforation gusset plate.
In such scheme, described perforation gusset plate inserts respectively arm and supervisor in mid-plane, and with mid-plane in arm weld together with supervisor, formation mid-plane K type node.
In such scheme, in described the first plane in arm, the second plane arm respectively with mid-plane K type node weld.
In such scheme, the large 2～4mm of twice of the maximum thickness of pipe of the Thickness Ratio node area of described perforation gusset plate.
In such scheme, described perforation gusset plate length in arm in mid-plane is 1.5～1.6 times of arm diameter and is more than or equal to 150mm.
The utility model proposes a kind of novel steel tube truss tubular joint form, and take appropriate measures and make ultimate bearing capacity of joints meet Structural Design Requirement.
Accompanying drawing explanation

In figure, 1-supervisor, arm in 2-mid-plane, 3-perforation gusset plate, arm in the 4-the first plane, arm in the 5-the second plane, L-perforation gusset plate length in arm in mid-plane, arm diameter in R-mid-plane, the length setting-out in being responsible for of H-perforations gusset plate, a-perforation gusset plate thickness, the maximum thickness of pipe of b-node area.
The specific embodiment
Below in conjunction with accompanying drawing, be further described:
As shown in Figure 1, 2, 3, a kind of spatial steel tube-truss three-dimensional K type tubular joint, it comprises arm 5 and perforation gusset plate 3 in arm 2 in supervisor 1, mid-plane, the interior arm 4 of the first plane, the second plane.
Described supervisor respectively with mid-plane in arm, the first plane in arm, the second plane arm form the K type in three planes, connect the junction that gusset plate is arranged in mid-plane and is arranged on the interior arm of mid-plane and supervisor, connect gusset plate and is connected with supervisor with arm in mid-plane, in supervisor, mid-plane, in arm, the first plane, the axis of arm, the interior arm of the second plane is all intersected in a bit on perforation gusset plate.
Described perforation gusset plate inserts respectively arm and supervisor in mid-plane, and with mid-plane in arm weld together with supervisor, formation mid-plane K type node.In described the first plane in arm, the second plane arm respectively with mid-plane K type node weld.
In practical operation, choose suitable perforation gusset plate 3, wherein connect gusset plate 3 thickness a than the large 2～4mm of twice of the maximum thickness of pipe b of node area; Connect gusset plate 3 length L in arm 2 in mid-plane and be 1.5 times of arm 2 diameter R in mid-plane and be more than or equal to 150mm; Connecting the length setting-out H of gusset plate 3 in supervisor 1 determines and is more than or equal to 200mm.By arm in mid-plane 2 and supervisor's 1 fluting, groove width is slightly wider than connecting gusset plate 3 thickness.Connecting gusset plate 3 inserts in supervisor's notch, to connect gusset plate 3 and the welding of tube wall penetration, then 2 arms in mid-plane are inserted and connect gusset plate 3, again by arm in mid-plane 2 and perforation gusset plate 3, supervisor's 1 welding, finally by arm in arm 4 in the first plane and the second plane 5 and supervisor 1 and to have welded in mid-plane arm 2 assembled, only weld visible lap weld, hidden weld seam is not processed.
