Abstract

A kind of manufacture method of trusses.At first will make skeleton 1 around a plurality of dividing plates 2 with a plurality of extensions 4 that composite material is made.Then around skeleton twine the line 5,5 of many tensionings ', make each extension 4 in the plane of each dividing plate 2 with wherein single line contact.Line can be bonded on the skeleton subsequently, and the thermoplasticity shell of the most handy fusing line also makes the method for its cementation.In light weight and the intensity height of the beam of this manufactured.

Description

The present invention relates to a kind of manufacture method of trusses.
Trusses is made with steel or composite material usually.Girder steel intensity is high but very heavy, therefore transportation inconvenience.The higher composite material beam of intensity will be made with the instrument division system, and this will increase producing cost inevitably.And this composite material beam is solid, makes beam become overweight.The present invention attempts to provide a kind of intensity height, and is in light weight, and easy to manufacture, the trusses that cost is low.
The invention provides a kind of manufacture method of trusses, it is characterized in that may further comprise the steps:
(a) make a skeleton that comprises a plurality of extensions that separate by a plurality of plane clapboards; With
(b) then around the flexible piece of backbone winding,, extension fixes thereby being contacted in the plane of each dividing plate with one of flexible piece with many tensionings.
Preferably on skeleton, the free margins of the dividing plate between the adjacent extension is contacted with flexible piece some flexible pieces.
Preferably each flexibility is fixed on its contact point with skeleton.
Extension is preferably hollow.
The most handy thermosetting or the resin of pad plasticity and the composite material of fiber of comprising of extension is made.
Used material is advantageously selected to the modulus of elasticity that makes them, and the numerical value of Poisson's ratio and proportion belongs to the same order of magnitude.
Each flexible piece is preferably all made with conductive material, and preferably covers thereon with one deck thermoplastic.
Preferably usefulness sticks to flexible piece on the skeleton by the way of electric current thereon.
The extension spaced-apart beams made from said method is made the beam of the very light in weight of unit length.Flexible piece is pressed to dividing plate with extension and is made with extension contact in the plane of each dividing plate and keeps between them closely cooperating.The beam of making so just can be used as solid memder and is used for machinery: flexible piece bears the most of stress that acts on the beam.Therefore this beam strength is high and in light weight.And it can do quite longly, without the segmentation manufacturing.
One embodiment of the present of invention are shown in accompanying drawing, wherein:
Fig. 1 is the phantom drawing along a pipe or three dividing plates of axle arrangement;
Fig. 2 is one and comprises Fig. 1 dividing plate and axle and by giving the phantom drawing of deciding the skeleton that adds pipe that mode arranges;
Fig. 3 has the phantom drawing that first line is wrapped in Fig. 2 skeleton on the pipe;
Fig. 4 has the phantom drawing that second line is wrapped in Fig. 3 skeleton on the pipe.
From accompanying drawing as can be seen, method of the present invention is from making skeleton 1.The dividing plate made from the composite material of glass fiber and thermalplastic resin 2 is along axis or manage 3 and install with same intervals.Axle or manage 3 and be placed on the vertical rotating turntable so that be easy to approaching during fabrication.To place by its allocation that gives with the extension pipe 4 that the same compound material is made then with respect to dividing plate 2.
Then many lines 5 are decided pattern and are wrapped on the skeleton 1 by giving.This pattern can be a spirality.Every pipe 4 collinear 5 contacts in the plane of each dividing plate 2.Each limit of each dividing plate 2 is crossed by the line between the adjacent pipe 45.And then add more line 5 ' to increase the stability and the intensity of beam.After the line 5 ' also that adds twine by spirality, but preferably the direction of spiral is opposite with the direction of first line 5.After the line 5 ' also that adds in the plane of each dividing plate 2 with pipe 4 contacts, each limit of each dividing plate 2 is also by the line between the adjacent pipe 45 ' cross.
The fuse that each bar line 5,5 ' all have conductive material is done and the shell of thermoplastic.Thereby make thermoplasticity shell fusing with line 5,5 ' be bonded on the skeleton 1 by energising on fuse.Thermoplastic resin in the composite material of pipe 4 and dividing plate 2 also is melted in the contiguous zone of collinear 5,5 ' contact point.At failure of current, line 5,5 ' cooling, thermoplastic resin just stick together line 5,5 ' same pipe 4 and dividing plate 2.
Though extension recited above is hollow, the solid bar of the solid bar that operating weight is lighter or filling also are acceptable with the hollow object of foam or synthetic materials.Extension around dividing plate can be made different arrangement, and the arrangement shown in the present embodiment is an example.The present invention is not restricted to the extension with composite material, it is contemplated that the extension of thin-wall steel tube or aluminum pipe also is suitable.
Flexible piece can be with steel or other metals, or comprises the line that high-tensile nonmetallic materials such as carbon or glass fiber reinforced epoxy are made, bar or band. Flexible piece can have a plastic casing, and can be bonded on the skeleton with being different from above-mentioned method, for example, directly heats to the pad plastic housing. Flexible piece also can be fixed on the two ends of skeleton or fix by periodic interval. Fixing method can be taked any suitable mode, such as binding, welds or repeats and twine. Pattern also can adopt non-helical shape, contacts with flexible piece as long as extend in the plane of each dividing plate.
A kind ofly be applicable to that the thermoplastic resin of the shell of extension and line is to be referred to as " I is close " material (Aramid) in Sweden. Also can adopt nylon. But these just for example.
Be appreciated that with such as the single flexible spare of line and so on from one of beam around to the other end. But also can be one by one the head of flexible piece being coupled together makes it twine back and forth along its beam length.
