Abstract

A multi-cavity ultralight ultrahigh-strength structural member for big-span beam, non-sinking ship, or movable building is composed of casing, and inflated internal containers or liners. Its advantages are high strength and rigidity, light weight and low cost.

Description

Ultra-strength superlight multi-cavity structural member with internal pressure and manufacture method thereof

The present invention relates to new material technology field, specifically a kind of ultra-strength superlight multi-cavity structural member with internal pressure and manufacture method thereof.

Various stress members in the present building, no matter be traditional building materials, resemble steel, timber, concrete or other new material, resemble aluminium alloy material, plastic-aluminum combined material, ubiquity undue body weight, and rigidity is not high, the unit price height is not suitable for various unsatisfactory problems such as batch production production.Though some have occurred by the structural member that the new construction material is formed both at home and abroad at present, all do not address the above problem, particularly be to do the roof of large span or the beam of other large span now, because the intensity of material, the problem of rigidity all can't solve.Also having present ship all is the heaviness that steel plate is made, the just sinking of a broken hole.

The objective of the invention is to design a kind of intensity height, good rigidly is pressed superpower structural meterials of ultralight and manufacture method thereof in lightweight multi-cavity is compound.

Ultra-strength superlight multi-cavity structural member with internal pressure of the present invention comprises shell, end cover, inflation non retern valve.Also have inflatable bladder and air-charging lining in the shell.Pressing the manufacture method of the super purport structural member of ultralight in a kind of multi-cavity is compound is to load onto inflatable bladder 5 in the shell 1, on the top when not in place, load onto the pressure-bearing pad, need not adorn when putting in place, refill and have the end cover 4 of inflating non retern valve 3, by inflation non retern valve 3 filling-foam agent and inflation to shell 1 in, make its foaming, allow foam be full of the interior space of its shell in set off.Inflatable bladder can be a horizontally-arranged, also can be vertical setting of types, and the cross section of horizontally-arranged inflatable bladder can be an inflatable bladder, also can be that two inflatable bladder are arranged, and also can be that three or more inflatable bladder is arranged.

The horizontally-arranged inner bag can be a whole inflatable bladder, and also can be that a plurality of inflatable bladder are bonding forms.

Pressing the advantage of the superpower structure of ultralight in multi-cavity of the present invention is compound is structural member intensity height, good rigidly, and in light weight, cost is low, and suitability for industrialized production is easy.Particularly to the beam column of large span, the purposes on top has extremely wide prospect.Inflatable bladder can be utilized present metal or polyester beverage can (bottle) simultaneously, accomplishes twice laid, has reduced environment pollution.

Below in conjunction with accompanying drawing embodiment is elaborated:

Fig. 1 is compound interior structure chart of pressing the superpower structural member of ultralight.

Fig. 2 is the sectional drawing of garden type structural member.

Fig. 3 is the sectional drawing of square structural member.

Fig. 4 is the many rows' of a plurality of inner bags of rectangle a structural member sectional drawing.

Fig. 5 is the single structural member sectional drawings of a plurality of inner bags of rectangle.

Fig. 6 is the structural member sectional drawing of polygonal many inner bags.

Fig. 7 is the vertical arrangement architecture spare sectional drawings of the many inner bags of long flat type.

Embodiment one, according to Fig. 1, Fig. 2 institute, all directly inwardly inflating in each inner bag 5 by non retern valve, make air pressure reach 0.3-0.6Mpa, the inner bag 5 of sufficient pressurising force is contained in the shell 1 by bonding being integral of number usefulness structure glue one by one that designed regulation needs, the hot piece 2 of pressure-bearing pad is loaded onto in place not in place, inner bag 5 tops in shell 1, if inner bag 5 puts in place and then can not adorn, method and shell 1 with welding of end cover 4 usefulness or sealing crimping are connected as a single entity, dress inflation non retern valve 3 on the end cover 4, blowing agent and air pressure are charged in the chamber of shell 1, foaming back shape occupies liner 6, and member is made like this.

Embodiment two: according to Fig. 1, shown in Figure 3, press Fig. 3 cross section with the square except shell 1, other the preparation method with embodiment one is the same.

Embodiment two: according to Fig. 1 and shown in Figure 4, shell 1 is by rectangle cross section shown in Figure 4, and inner bag 5 cross sections are done outside horizontally-arranged arranges, other the same with embodiment one preparation method.

Embodiment four: press garden type cross section shown in Figure 5 according to Fig. 1 and shell shown in Figure 51, outside inner bag 5 cross section four lines were arranged by upper and lower, left and right, other the preparation method with embodiment one was the same.

Embodiment five: according to Fig. 1, shown in Figure 6, shell 1 is by polygon cross section shown in Figure 6, the cross section triplex row of inner bag 5 by the garden heart of inner bag 5 connect be triangularly arranged outside, other the same with preparation method with embodiment one.

Embodiment six: according to Fig. 1, shown in Figure 7, shell 1 is pressed rectangular cross section shown in Figure 7, and with outside the bonding 7 row arrangements of structure glue, other is the same with embodiment one preparation method for perpendicular for inner bag 5.

Claims
