Description
Technical field
The present invention relates to building material field, particularly a kind of sealed tube core type composite plate and load-bearing material for building.
Background technology
In building trade, construction material is especially important, and beam, plate or vertical in building is made by combination in construction material
Column.
With industrialization and the propulsion of modernization, because cement plate has more preferable support strength, modern society uses mostly
Cement plate is as base materials such as beam, columns, so that house is more firm.However, can be existed as construction substrate using cement plate
Such as easily disturbed from great, long construction period, construction period and not environmentally the shortcomings of.In order to solve the problems, such as these, building trade
Start using metal material as construction substrate.
In the prior art, generally use solid steel plate, using the high-intensity performance of steel, carries out house as construction substrate
Framework construction.But this usual materials of mode are more, although can ensure the intensity of building when for skyscraper,
It can bring from the problems such as great, waste of material is more；During the installation and lifting of building board is carried out, since volume is big, weight
Amount weight, can greatly increase the labor intensity of construction personnel, and there are some potential safety problems.
The content of the invention
A kind of materials are provided and are saved, from heavy and light, structural strength the purpose of the present invention is overcoming the above-mentioned deficiency of the prior art
Height, antiseptic property is good, the sealed tube core type composite plate of high insulating effect and load-bearing material for building.
The technical scheme is that：
A kind of sealed tube core type composite plate of the present invention, includes top panel, lower panel and arranged on the die layer between them, the pipe
Sandwich layer arranged by several tube bodies after with top panel, that lower panel is connected shape is integral；The tube body is the closing of inner hollow
Formula structure.
The present invention links into an integrated entity die layer and top panel and lower panel, on the one hand while material is saved, moreover it is possible to
Guarantee top panel and lower panel can be dispersed on each tube body after being stressed by die layer, so as to reduce the whole of composite plate
Body stress, and then increase the integral strength of structure；On the other hand, realize lightweight significantly, and due to light-weight, be easily installed
And lifting, the labor intensity of operating personnel is greatly reduced, improves security.In short, the composite plate of the present invention with it is existing each
Kind plate is compared to there are advantages below：（1）Under equality strength, materials are minimum；（2）Under equivalent weight, maximum intensity.
In addition, pass through the enclosed construction by shaft design into inner hollow so that upper and lower panel is easy to upper with tube body
Lower both ends welding, reduces the difficulty with solder connection, welding is disposably completed, and substantially reduce rejection rate；On the other hand,
The linkage interface intensity between tube body and solder can be improved, and then improves the tensile strength of whole welding surface and impacts heat and answer
Power.
Further, articulamentum is equipped between the die layer and top panel and lower panel, the articulamentum is by soldering, resistance
Weldering, Laser Welding or bonding mode are formed.By die layer and top panel and lower panel welding or be glued and form one, when top panel and
When lower panel is stressed, it can be dispersed into by die layer on each tube body, laterally and vertical applied force is small, is unlikely to deform, from
And the integrated stress of composite plate is reduced, and then increase the integral strength and stability of structure.When die layer and top panel and following
It is very low to the susceptibility of environmental change when plate uses welding manner, persistence length.Present invention preferably employs brazing mode, energy
Enough make being more uniformly stressed for total.
Further, the thickness of the articulamentum is 0.5 ~ 2mm.The thickness range be able to ensure that by die layer and top panel,
Shaping is fastened between lower panel, even if being subject to larger stress, loosening will not be produced.If being less than 0.5mm, fastness is poor；If
More than 2mm, especially in welding process, solder is not only wasted, but also causes weld interval length, and easily damages tube body.
Further, the tube body is groove profile pipe, I-shaped pipe, angle-style pipe, T-shaped pipe, curved pipe or yi word pattern pipe.These pipes
The joint face of body and upper and lower panel is closed, and greatly improves welding quality, rate of reducing the number of rejects and seconds.Wherein, if above-mentioned tubular body is spaced
When being distributed between top panel and lower panel, the bonding strength of groove profile pipe is maximum, and the bonding strength of yi word pattern pipe is minimum.Therefore exist
When being intervally arranged, the arrangement interval of yi word pattern pipe is less than other tube bodies, with the structural stress that increase is overall.In addition, curved pipe
Arcuate structure can be semicircle or more than semicircle.
Further, the material of the tube body is stainless steel tube.Stainless steel, which has, meets the rustless characteristic of water, due to room
Room needs to be subjected to scrubbing for rainwater, and after long-term rain wash is subjected to, the steel frame construction in house is easily corroded be subject to rainwater,
It using stainless steel, then can prevent steelframe from making moist to get rusty, so as to extend the service life in whole house, can ensure in theory whole
A house is forever not bad.
Further, the top panel and/or lower panel are metallic plate or carbon plate.Carbon plate is swollen with high temperature resistant, rapid heat dissipation, line
The advantages that swollen coefficient is low, intensity is high, corrosion-resistant and light weight, and carbon plate is easily molded, easy to process, cost is low.And metallic plate
It is big with intensity, corrosion resistant advantage.
Further, the material of the top panel and/or lower panel is in stainless steel, fiberglass, carbon steel, titanium steel or aluminium alloy
One kind.
Further, the pipe thickness of the tube body is 0.1 ~ 3mm.Pipe thickness is arranged in the interval range, it is both real
Lightweight is showed, and has reduced thermal conductivity factor, if being less than 0.1mm, integrally-built intensity can have been reduced, and tube body is easily curved
Folding, if being higher than 3mm, can increase thermal conductivity factor, and increase material cost.
Further, it is spaced between the tube body, or the mutual jam-packed compression in side of the adjacent tube body, decrement
For 2% ~ 5%.
By being spaced, it is possible to reduce the quantity of tube body and overall weight, reduce cost.In addition, the arrangement of tube body
It can be order arrangement or symmetric arrays, can also be that opposite type arranges, or be between these types of arrangement architecture
Interactive arrangement etc..
Compressed by mutual jam-packed, prevent from leaving gap between the side of adjacent tubes, when top panel and lower panel are subject to
After stress, if leaving gap between the side of adjacent tubes, tube body is easily set to produce bending, displacement or loosen, substantially reducing makes
Use the service life.It is because the scope enables to tube body not curved after being stressed in the range of decrement is arranged on 2% ~ 5%
Roll over, suffered active force is cancelled out each other between tube body, so as to improve overall structural strength.
Further, between the tube body at intervals of 10 ~ 50mm, in such manner, it is possible to improve integral strength.If tube body interval is too
Greatly, overall structural stress can be reduced, if tube body interval is too small, overall weight and cost reduction be not notable.
Further, the thickness δ of the top panel and/or lower panel is：0.5≤δ≤6mm.Composite plate is used in different
Under occasion, the thickness of its panel is different, and in general, setting is optimal within the above range, if being less than 0.5mm, can drop
Low integrally-built intensity, and it is not easy to be processed, if being higher than 6mm, weight can be increased, not easy to install and lifting, and increase material
Cost.
For example, when being used to make the column and beam of construction material energy load-bearing by composite plate, the active force that it bears is larger,
Therefore relatively thick panel is selected, the thickness of top panel and lower panel may be the same or different.Top panel and lower panel
Thickness depending on the floor number of plies：When floor is higher, it is stressed smaller, then should selects relatively thin panel, and δ values are with building
The increase of layer height and reduce；When floor is relatively low, it is stressed larger, then should selects thicker panel, and δ values are with story height
The reduction of degree and increase.
When composite plate to be used to make floor, the active force born for column and crossbeam is smaller, therefore whole
The thickness of body is relatively small, on the basis of integral strength is ensured, also reduces dead weight.
Further, the top panel and lower panel make the shape of peripheral flanging, encase die layer；Or welding weldering used
The edge flange of material, encases die layer.In this way, one is that die layer can be prevented to be worn, second, can prevent most on side
Tube body produces loosening, by peripheral flanging, mutual active force can be produced between the tube body most on side, will not make tube body list
Only stress and phenomena such as produce loosening.
A kind of load-bearing material for building of the present invention, is made of foregoing sealed tube core type composite plate.
Load-bearing material for building includes beam, column or plate.Wherein plate can be floor, lining, Side fascia, roofing board etc..
