Abstract
The utility model relates to a glass fiber reinforced plastic laminated plate with embedded steel hollow beams, which comprises an upper layer and a lower layer which are mutually stacked. The upper layer and the lower layer are both made of a plurality of glass fiber braided fabrics, a plurality of the steel hollow beams are parallelly arranged between the upper layer and the lower layer at intervals, each steel hollow beam with two closed ends penetrates through the glass fiber reinforced plastic laminated plate, and the cross sections of the steel hollow beams are rectangular or trapezoidal. The glass fiber reinforced plastic laminated plate has the advantages of high intensity and small deformation rate, can be directly connected with a main unit frame of an wind power generator without other metal support parts for assisting, realizes stressed support of an engine room cover and a diversion cover, is simple in processing technique, low in production cost, few in production processes, and can be widely applied to manufacturing engine room covers, diversion covers and the like of wind power generators.
Description
Technical field
The utility model belongs to technical field of wind power generator, especially a kind of frp layer pressing plate of pre-buried steel cored beam.
Background technique
The frp layer pressing plate that uses in the products such as common cabin cover of wind power generator, air guide sleeve mostly by fiberglass braided thing as reinforcing phase, thermosetting property or thermoplastic resin are made through laminating technologies such as hand pasting forming, resin transfer molding, vacuum assisted resin importing moulding as continuous phase.But the engine room cover of glass fibre reinforced plastic material and air guide sleeve can not be made very thickly for fear of its product performance, and this has just limited the further raising of glass fibre reinforced plastic material intensity.The cabin cover of wind power generator of main flow all adopts a large amount of angle steel to be used for the edge reinforcement of glass fibre reinforced plastics engine room cover and being connected of each glass fibre reinforced plastics cabin housing at present, adopt a large amount of angle steel to be used for the support of engine room cover simultaneously, not only make the weight of wind-driven generator increase, the use of simultaneously a large amount of angle steel also causes the damage of glass steel shell easily.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of frp layer pressing plate of one-body molded, with low cost, pre-buried steel cored beam that intensity significantly improves is provided.
The technological scheme that the utility model is taked is:
A kind of frp layer pressing plate of pre-buried steel cored beam, comprise the upper and lower that stack mutually, the upper and lower constitute by the laminated glass fibrous braid, and it is characterized in that: parallel interval is provided with the steel cored beam of a plurality of perforation frp layer pressing plates and closed at both ends between the upper and lower.
And the cross section of described steel cored beam is a rectangle or trapezoidal.
Advantage of the present utility model and good effect are:
The utlity model has intensity height, advantage that deformation rate is little, under the situation auxiliary without other metallic supports, can directly be connected with the wind-driven generator mainframe, realize the stressed support of engine room cover and air guide sleeve, and processing technology is simple, cost of production is low, and production process is few, can be widely applicable for the manufacturing of products such as cabin cover of wind power generator and air guide sleeve.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the cross-sectional view of Fig. 1.
Embodiment
Below in conjunction with embodiment, the utility model is further specified, following embodiment is illustrative, is not determinate, can not limit protection domain of the present utility model with following embodiment.
A kind of frp layer pressing plate of pre-buried steel cored beam, shown in Fig. 1～2, comprise the upper and lower that stack mutually, the upper and lower constitute by the laminated glass fibrous braid, innovation of the present utility model is: parallel interval is provided with the steel cored beam 1 of a plurality of perforation frp layer pressing plates and closed at both ends between the upper and lower, the cross section of this steel cored beam is a rectangle or trapezoidal, can certainly adopt the grid network shape structural member that is welded by a plurality of independently steel cored beams.
In the present embodiment, the steel cored beam is two, and the cross section of each steel cored beam is trapezoidal.The upper strata is by 900g/m
2The first compound carpet veneer 2,900g/m
2Second compound carpet veneer 3 and the 900g/m
2The 3rd compound carpet veneer 4 stack formation mutually.Lower floor is by 1080g/m
2The first sandwich carpet veneer 5,1500g/m
2The 4th compound carpet veneer 6,1500g/m
2The 5th compound carpet veneer 7 and 1080g/m
2The second sandwich carpet veneer 8 stack formation mutually.
Manufacture method of the present utility model is:
1. mould fully cleans, and applies releasing agent;
2. the lay second sandwich carpet veneer, the 5th compound carpet veneer, the 4th compound carpet veneer and the first sandwich carpet veneer from bottom to up successively make progress, put two steel cored beams in the upper surface parallel interval of the first sandwich carpet veneer, and then lay the 3rd compound carpet veneer, second meets the carpet veneer and the first compound carpet veneer;
3. about the upper surface lay of the first compound carpet veneer and between the upper and lower apart from the honeycomb duct that is 1m, and covering vacuum bag film;
4. at mould outside lay exhaust pipe, bleed, make internal pressure in the mould that the vacuum bag film covers less than-0.096Mpa, in mould, inject the unsaturated polyester resin of the interpolation certain proportion methyl-ethyl ketone peroxide curing agent of capacity, after every layer of braided fabric soaked into fully by resin, solidifying is removed vacuum bag film and honeycomb duct, promptly obtains the frp layer pressing plate finished product of pre-buried steel cored beam.
By above-mentioned manufacturing process as can be known, vacuum assisted resin imports the major parameter of forming method, need not to adjust as the laying of the thickness of vacuum bag film and model, honeycomb duct, vacuum pressure etc.Also can adopt the hand pasting forming method, earlier with lower floor's hand pasting forming, fixing steel cored beam then, the layering hand is pasted the fiberglass braided thing of layer over again.As seen the introducing of steel cored beam does not impact processing technology, can adopt conventional production method to produce.
The utility model uses a plurality of steel cored beams, significantly improved the bending resistance of frp layer pressing plate, significantly do not increasing under the glass fiber laminate condition of cost, use the steel cored beam in the frp layer pressing plate promptly can realize being connected of engine room cover and air guide sleeve product, saved a large amount of structural members, and processing technology is simple, and cost of production is low, can be widely applicable for the manufacturing of products such as cabin cover of wind power generator and air guide sleeve.
