Five, the specific embodiment
Be further described concerning between each member of truss of the present invention below in conjunction with accompanying drawing.
Fig. 1 is a tenon bolt node aluminium alloys truss structural, and its all rod members are all made with aluminum alloy materials.Upper chord and lower chord are square type square tube section rod members, and form of fracture can be the single hole square tube, also can be the porous square tube, can establish rib on the square tube wall.Thin portion such as chord member length, cross dimension and square tube wall thickness size all designs according to actual engineering.All web members (2), (3), (4) also are the rectangular cross section rod members; Can be single hole or porous square tube, for the less truss web of span, internal force be less; Also can select the entity rod member, thin portion such as web member length, cross dimension size is also confirmed by actual engineering design.
From Fig. 2 and Fig. 4 and Fig. 3 and Fig. 5, see chord member (1) and web member (2), (3) (4) pair relationhip of tenon and tongue-and-groove each other.Fig. 2 and Fig. 4 are that the tenon plate (5) on the chord member (1) is implanted in the tongue-and-groove (6) of web member (2), (3), (4), and be fastening with bolt or riveting bolt.Fig. 3 and Fig. 5 are that the tenon (9) of web member (2), (3), (4) is implanted in the tongue-and-groove (8) of chord member (1), and be fastening with spiral shell inspection or riveting bolt.Take which scheme to carry out tenon and tongue-and-groove combinations of pairs in the actual engineering, confirm according to reality by the designer.The tenon plate can be a solid plate, also can be hollow slab.Tongue-and-groove both sides cell wall can be that solid plate also can be a hollow slab.The relative dimensions of tenon and tongue-and-groove is confirmed by concrete engineering design.
Link fastening with stainless steel bolt or riveting bolt (7) between tenon rod member and the tongue-and-groove rod member.Bolt or riveting bolt diameter and quantity are confirmed according to actual engineering.
Embodiment one: certain factory building truss purlin beam, 9 meters (see figure 6)s of span
Scheme 1:Q235B steel pipe welded truss, every Pin steel using amount is 122kg, by 5000 yuan per ton, every Pin cost is 610 yuan.
Scheme 2: the tenon bolt node plane frame of using six line aluminium alloy made instead.Because span is less, the rod member section is also less, and decision adopts ∏ type section entity chord member as chord member tongue-and-groove rod member, with single hole square tube web member as tenon rod member combinations of pairs with it; Perhaps use T type section entity chord member as chord member tenon rod member, match with it as web member tongue-and-groove rod member with the single hole square tube of two rod end openings.The every Pin of tenon bolt node aluminium alloys truss aluminium alloys 41kg, by 22000 yuan per ton, 902 yuan of every Pin costs.
Embodiment two: certain factory building truss leg, the high 6 meters (see figure 7)s of post
Scheme 1:Q235B steel pipe welded truss post, every Pin steel using amount 128kg, by 5000 yuan per ton, every Pin cost is 640 yuan.
Scheme 2: use six line aluminium alloy tenon post node truss legs instead, every Pin aluminium alloys 40kg, by 22000 yuan per ton, 880 yuan of every Pin costs.
Find out that from above embodiment though the every Pin cost of aluminium alloys truss is higher than steel truss, yet its every Pin weight only is about 30% of steel truss.Alleviated the deadweight of building greatly, to the pillar and the basic economical with materials of lattice, it is very favourable to reduce construction costs, has also further improved the anti-seismic performance of structure simultaneously.
Aluminum alloy materials anti-corrosive properties, durability are that other metals such as steel are incomparable.Detection was done by relevant department, and the thickness that aluminium loses because of corrosion every year is 0.5 micron, and through 50 microns of losses after the atmospheric corrosion in 100 years, promptly 0.05mm is inappreciable.Aluminum alloy materials almost need not safeguard all the life, the engineering that is that a life of a hundred years.Above-mentioned instance calculates steel truss structure (by 30 year service life) 20.33 yuan of costs every year on average by annual cost, and also will drop into a no small maintenance cost every year.And aluminium alloys trussed construction (by 70 year service life) 12.98 yuan of costs every year on average need not drop into maintenance cost again, and overall economic efficiency also is fairly obvious.
