Abstract
The invention discloses a spacial steel roof truss. The roof truss has a triangular section; upper and lower chords of the roof truss are not positioned in the same plane; and compared with a planar roof truss, the spacial steel roof truss can greatly reduce support systems of the roof truss and has higher stability than the planar roof truss system. The upper chord of the triangular spacial roof truss is made of H-shaped steel, and web members and the lower chord are made of steel pipes, so the spacial steel roof truss gives full play to good axial pressure and bending moment bearing performance of the H-shaped steel and the good mechanical property of members, and has the advantages of economic and reasonable structure, simple and convenient construction, and safety and reliability. Compared with the traditional roof truss, the spacial steel roof truss can save a great deal of investment, shorten site construction period and reduce steel consumption of the roof truss, the height of the roof truss and comprehensive cost, and has good safety performance. An electrolytic plant is a heat insulating plant; and because the height of the roof truss is reduced, the height of the plant can be reduced, the volume of the plant is decreased, and the energy can be saved after the plant is put into production and use.
Description
Technical field
The present invention relates to a kind of building structure roof truss form, relate in particular to a kind of spacial steel roof truss at the copper smelting industry.
Background technology
At present, the cupric electrolysis workshop all is to adopt the planar trapezoidal steel-pipe roof structure basically, and roofing adopts the prefabricated reinforced concrete plate, and this roof structure system roofing is big from heavy load, roof truss support system complexity, and the structural steel amount is big, long construction period.
Summary of the invention
The object of the present invention is to provide a kind of triangular-section spacial steel roof truss, this roof truss can reduce the roofing height, shortens construction period, reduces cost, and energy conservation has overcome former roof truss roofing from great, long construction period, the shortcoming that structural cost is high.
A kind of spacial steel roof truss, it is characterized in that: roof truss adopts section triangle, the last lower edge of roof truss is not at grade, by web member lower chord on the roof truss is formed stable support, thereby roof truss self forms a stable space structures system, compare the support system that can significantly reduce roof truss with the plane roof truss, stability is much better than plane roof truss system.
A kind of spacial steel roof truss, it is characterized in that: the triangle space roof truss winds up and adopts H shaped steel, web member and lower chord adopt steel pipe, H shaped steel has the good performance of bearing axial pressure and moment of flexure, and steel pipe has the good performance of bearing axial force, and the electrolysis roof truss winds up and bears axial pressure and moment of flexure, web member and lower chord bear axial force, given full play to the good stress performance of rod member, structure economics is reasonable, and is safe and reliable.Compare with traditional roof truss and can save great amount of investment.
Good effect of the present invention is: 1, shortens the site operation duration, reduces integrated cost, and primary plane roof truss poor stability, support is many, long construction period.And roof truss of the present invention self is a stable space structures system, supports and lacks, short construction period.2, security performance is good, primary plane roof truss longitudinal tie rod spacing is generally about 6m, poor stability, and employing the present invention, roofing chord member nodal pitch is about 3m, stability improves greatly, and the strength of materials is fully used, and the structural safety performance is improved, 3, the structure economics effect is obvious, reduced the roof truss steel using amount, reduced the roof truss height, cell room is the insulation factory building, because the reduction of roof truss height, thereby can reduce factory building height, reduce the volume of factory building, can energy conservation after factory building puts into production use.

The specific embodiment
Describe embodiments of the present invention in detail below in conjunction with accompanying drawing:
Concrete enforcement of the present invention should be finished by construction steel structure construction, Installation unit that corresponding construction qualification is arranged, and concrete enforcement is main to divide factory's processing and fabricating and on-the-spot two stages of installation.
The processing of steel roof truss is adopted in factory process and is made, and at first purchases raw material and welding material, is ready to welding equipment.Upper chord 2 is a welded H section steel, web member 4 and lower chord 3 are the finished product ratio-frequency welding and take over, the processing and making process of welded H section steel is: earlier by cross section requirement cutting steel plate, to fix with spot welding earlier between the steel plate then, adopt submerged arc welding machine that the whole member weld seam is welded again, web member 4 lower chords 3 are purchased the fished pipe of design, according to designing requirement steel pipe are carried out the correlation cutting; Process gusset plate according to designing requirement.Be exactly the assembly unit welding after upper chord 2, web member 4, lower chord 3, gusset plate are ready to, adopt local electric welding location during welding earlier, adopt automatic submerged arc welding that each bar weld seam is welded then.Should proofread overall dimensions repeatedly in the process, avoid producing too great deviations.Steel roof truss roofing chord member nodal pitch of the present invention is about 3m, and stability improves greatly, and the strength of materials is fully used, and the structural safety performance is improved, and roofing gradient 1: 10 makes things convenient for roof drainage.Carrying out sandblast or impeller blasting after welding is finished, is two times priming paint of spraying at last.Should check pre-embedded bolt location, civil engineering post 1 top before the on-the-spot installation, confirm that beginning steel truss after errorless lifts, and adopts two point symmetry colligations to lift by crane installation in place during lifting.In place slowly when steel truss lifts by crane the back apart from post datum 100mm, treat to dock the adjustment correction behind the steel truss hoisted in position, fixedly connected then.With hanging, there is deviation to correct at any time during the steel truss lifting with proofreading and correct with transit.Install after adjacent truss lifting is finished at once and support, lift roof purline, roof panel system at last.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention; make some alternative or obvious modification that are equal to without departing from the inventive concept of the premise; and performance or purposes are identical, then should be considered as belonging to the protection domain that the present invention is determined by claims of being submitted to.
Claims (2)
1. spacial steel roof truss is characterized in that: roof truss adopts section triangle, and the last lower edge of roof truss forms stable support by web member to lower chord on the roof truss not at grade, thus stable space structures system of roof truss self formation.
2. spacial steel roof truss according to claim 1 is characterized in that: triangle space roof truss steel truss winds up and adopts the H section steel manufacture, and lower chord and web member adopt steel pipe.
