Abstract
The utility model relates to a net frame structure. The net frame structure comprises a net frame body formed by connecting a plurality of rod pieces in a staggered manner, wherein the rod pieces are of hot-rolled seamless steel pipes, stiffening ribs are welded on at least one rod piece, and the stiffening ribs are arranged along the axial direction of the rod piece. By utilizing the structure, the rigidity of a member can be effectively increased by welding the stiffening ribs on the rod piece, and the rod piece further has greater bearing capacity. In addition, as for the situation of reinforcing an original net frame structure which often appears in reconstruction and expansion projects, the rigidity of the member can be effectively increased by welding the stiffening ribs on the rod piece for a pressure rod which does not achieve the bearing capacity, so that the bearing capacity under stress of the member after reinforcing can meet the design requirements, and the problems of difficulty in construction and greater loss of materials of a processing form of directly replacing or externally wrapping a steel pipe with larger diameter in the prior art can be further solved.
Description
Technical field
The utility model relates to building structure field, is specifically related to a kind of space truss structure.
Background technology
At building field, especially, tend to adopt space truss structure for than longspan structure.Space truss structure is selected for use the steel pipe of different-diameter to be cross-linked as rod member according to stressing conditions usually and is formed.But diameter of steel tube too conference causes waste of material.In addition,, occur needing original structure is reinforced, wherein just comprise rack through regular meeting along with the enforcement of at present a large amount of reconstruction and extension projects.To the processing that does not reach the requirement for bearing capacity depression bar generally is the steel pipe of a directly replacement or a larger diameter of outsourcing.These two kinds of methods all exist constructional difficulties and the bigger problem of consumable material.
Summary of the invention
The purpose of the utility model is to provide a kind of space truss structure, and this space truss structure can be issued to bearing capacity in the situation of less rod member diameter.
The technical scheme that realizes the utility model above-mentioned purpose is: a kind of space truss structure, comprise by some rod members being cross-linked the rack body of forming, and rod member is a hot rolled seamless steel tube, wherein is welded with stiffening rib at least one rod member, stiffening rib axially is provided with along rod member.
The stiffening rib that welds on the said rod member is 3-5, and this 3-5 stiffening rib is distributed on rod member tube wall week side.
The utility model through on rod member, welding the rigidity that stiffening rib effectively increases member, makes rod member have bigger bearing capacity owing to adopt said structure.In addition; For the situation that original space truss structure is reinforced that often occurs in the reconstruction and extension project; Can be to not reaching the depression bar of bearing capacity; Effectively increase the rigidity of member through welding stiffening rib on rod member, make the compression bearing of reinforcing the back member meet design requirement, directly replace in the prior art or the existing constructional difficulties of processing form and the bigger problem of consumable material of the steel pipe of a larger diameter of outsourcing to solve.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is an A-A profile among Fig. 1.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Referring to Fig. 1-Fig. 2; The utility model comprises by some rod members 2 and is cross-linked the rack body of forming 1; Rod member 2 is a hot rolled seamless steel tube; Wherein be welded with stiffening rib 3 (confirming the rod member that required welding stiffening rib is reinforced according to stressing conditions) at least one rod member 2, stiffening rib 3 axially is provided with along rod member 2.
The stiffening rib of welding is 3 on the said rod member 2, and these stiffening ribs are distributed on rod member tube wall week side.
The utility model makes rod member have bigger bearing capacity through on rod member, welding the rigidity that stiffening rib effectively increases member.In addition; For the situation that original space truss structure is reinforced that often occurs in the reconstruction and extension project; Can meet design requirement through on rod member, welding the rigidity that stiffening rib effectively increases member, make the compression bearing of reinforcing the back member to not reaching the depression bar of bearing capacity.Compared with prior art, the utility model is the most direct, most effective to the rigidity that improves rod member, stiffening rib handling ease, construction and installation flexible arrangement.Reinforce back rod member compressive strength and obviously promoted, there is very positive meaning reinforcement cost, the reduction of erection time of reducing engineering.
Embodiment 1
Application examples: certain engineering rack is after construction finishes, and the Party A has proposed new requirement to design, causes load to change.Through checking computations, find that part rod member compressive strength (stablizing) can't satisfy new designing requirement, needs reinforcement.Rod member for grid is hot rolled seamless steel tube.
Wherein the rod member model of a need reinforced pole is 203X12 (radius of gyration 6.77cm, every meter weight 56.52kg/m), need reach 7.0cm if will satisfy its radius of gyration of new designing requirement.
If with its rod member model of directly replacing then replacement is 219X14 (radius of gyration 7.26cm, every meter weight 70.78kg/m); If adopt steel clad reinforcement, Baogang's model is 219X8 (radius of gyration 7.47cm, every meter weight 41.63kg/m).
If adopt this new and practical method then only to need around former rod member, to weld three stiffening ribs, the angle between stiffening rib is 120 degree, and the cross section is 6X50.The total sectional area of three stiffening ribs is 9.00c ㎡ only, and every meter weight is 7.07kg/m; More directly replacement method is practiced thrift steel using amount 90%, reinforces than Baogang's method and practices thrift steel using amount 83%.Reach 8.34cm with former rod member welding rear fitting radius, can satisfy new designing requirement fully.
Claims (2)
1. a space truss structure comprises by some rod members being cross-linked the rack body of forming, and rod member is a hot rolled seamless steel tube, it is characterized in that: wherein be welded with stiffening rib at least one rod member, stiffening rib axially is provided with along rod member.
2. space truss structure as claimed in claim 1 is characterized in that: the stiffening rib that welds on the said rod member is 3-5, and this 3-5 stiffening rib is distributed on rod member tube wall week side.
