Description
One, technical field
The present invention relates to a kind of beam, is the field of civil engineering structural member commonly used of building construction, bridge construction.
Two, background technology
Allly be commonly referred to beam with the rod member that is bent into main distortion.Beam is a kind of rod member of civil engineering extensive use.Common have floor beam, roof girder, wall beam, rigit-frame beam, roof purline beam or the like.By the manufacturing materials branch reinforced concrete beam, girder steel, wooden frame, steel and concrete composite beam are arranged.Sectional form branch by beam has the rectangular cross section beam, and tee-section beam, girder steel have I-steel, channel-section steel, H shaped steel, C shaped steel, Z-shape steel, steel square tube, steel garden pipe etc.
Aluminum alloy materials light weight (proportion be steel 1/3rd), high-strength (physical and mechanical property of six serial aluminiums is near the Q235 of construction steel), the efficiency of preservation height 4-6 of steel (be doubly), good moldability (being that other metals are not comparable), be the environment protection architecture metal that to regenerate, be widely used in door, window, curtain wall and other finishing building engineering field at present.Porous box-shaped aluminum alloy beams of the present invention, be exactly according to the characteristics of aluminum alloy materials and the loading characteristic of beam, create porous box-type aluminum alloy beams rod member, it is stressed reasonable to obtain, reliable in structure, economical with materials can be applicable to the aluminum alloy beams member of the parts such as room beam, wall beam, purlin beam of civil engineering.
Three, summary of the invention
1, purpose of the present invention
The distortion of beam under external force mainly is flexural deformation.Beam when flexural deformation, a side fiber pressurized on its cross section and shortening, opposite side fiber tension on the cross section and extending.Normal stress is respectively corresponding pressure zone and tensile region on the beam cross section, and maximum crushing stress is created in the outermost edge place of pressure zone on the cross section, and maximum tension stress is created in outermost edge place in tensile region on the cross section.Construction material is at elastic stage, and the cross section maximum crushing stress carries out the transition to maximum and draws stressed to be linear change, a neutral axis is arranged in the middle of the cross section.The stress distribution and the deformation characteristics of Here it is beam.The same plastic material that belongs to together of aluminum alloy materials with structural steel, its compressive strength equates with tensile strength, and the mouldability of aluminum alloy materials is better, has the advantages that to be convenient to machine-shaping.Purpose of the present invention is exactly the quality according to above-mentioned two characteristics " distribution according to need " beam section, finds the potentiality of bringing into play the strength of materials to greatest extent, saves material again, makes things convenient for " reasonable section " beam of processing and fabricating again.Calculate by analysis, creativity and innovation porous box section aluminum alloy beams (see figure 2).
2, technical solution of the present invention
Porous box-shaped aluminum alloy beams aluminum alloy materials, the use pressing method is made, it is by upper and lower tank wall, left and right tank wall, the aluminium alloys plate of the both sides case wing and interior case rib constitutes, it is characterized in that: according to the stress distribution of beam cross section and the characteristics of stress intensity, the position and the quality size thereof of the above-mentioned various plates of reasonable corresponding layout box-girder are brought into play strength of materials potentiality to greatest extent; Improved simultaneously rigidity and out-of-plane rigidity in the stability of beam and the plane to greatest extent, it is a kind of stressed reasonable to obtain, and economical with materials is easy to " reasonable section " beam column spare of processing and fabricating.
1. tank wall is arranged in the outward flange of beam cross section pressure zone on the above-described aluminium alloys, i.e. maximum crushing stress place, and its cross section wall thickness is determined by designing and calculating according to the load of beam span and effect.Last tank wall tabular has two schemes: the first is made surface plate; It two makes stupefied panel.

It below is a case history of the present invention
Southern china factory building roof purlin beam, span L is 12m, roof panel is " 0.7+75+0.6 " glass fiber lap felt dual-layer colour steel plate.
Scheme 1: the former Q235B H shaped steel purlin (Fig. 5) that is designed to, high 300 webs of beam section are thick 6, and the upper and lower edge of a wing is wide by 150, edge of a wing thickness of slab 4.5.Every beam steel 291.64kg, by 5000 yuan per ton, every beam cost is 1458.20 yuan.
Scheme 2: using six line aluminium alloy material manufacturings instead, with surface plate tank wall porous box aluminum alloy beams scheme (Fig. 4), is 103.29kg with the aluminium amount, and by 22000 yuan of calculating per ton, every beam cost is 2272.38 yuan.
Find out from above-mentioned case history, under kindred circumstances, though every cost of aluminum alloy beams is higher by about 36% than girder steel, yet its weight only is about 30% of girder steel, alleviated the deadweight of building greatly, roof truss beam to the supporting purlin reaches surface member and basic economical with materials down, and it is very favourable to reduce construction costs.Moreover porous box-type section beam, outside in the plane and the plane, rigidity is all much bigger than H shaped steel.
The aluminum alloy materials mouldability is better than steel, can be convenient to a large amount of productions by the extrusion process one-shot forming.The supporting uses of member such as aluminum alloy beams and aluminium alloys girder truss, aluminum alloy roof plate can accomplish that with the material homogeneity, thermal stresses and modification are synchronous, have improved the building safety degree.
Aluminum alloy materials efficiency of preservation height, though the cost that the aluminium alloys building unit is built is high slightly, several exhaling throughout one's life need not safeguard, the engineering that becomes that a life of a hundred years, it uses cost very cheap, and economic benefit is very obvious.
