Abstract
The invention relates to a method for compensating the planeness of longitudinal beams of a composite plate beam member, providing a method capable of making I-shaped longitudinal beams or C-shaped longitudinal beams on the same plane and eliminating assembly stress. The method comprises the following steps of: (1) coating resins on glass cloth; (2) laying preimpregnation materials into blanks; (3) laying the laid blanks on the upper surfaces of the longitudinal beams to make compensating layers; (4) solidifying; and (5) processing the compensating layers. The invention has the advantages of enabling the upper surfaces of the I-shaped longitudinal beams or the C-shaped longitudinal beams on the same plane, eliminating the assembly stress and prolonging the service life of products.
Description
Technical field: the invention is the method that increases layer of compensation in the slab and girder spare made from composite material on the longeron, guarantees the flatness of many longeron fitting surfaces through the processing back.
Background technology: with the covering spare of composite material manufacturing and the slab and girder spare of longeron spare formation, wherein often to adopt the cross section be " worker " shape longeron and/or " C " shape longeron to longeron, because of some reason causes " worker " shape longeron and/or " C " shape longeron height difference, its upper surface is not or not same plane, can cause during assembling and produce the gap between the built-up member, cause being with the stress assembling.
Summary of the invention: the purpose of the invention provides a kind of making " worker " shape longeron and/or " C " shape longeron upper surface is in the method for compensating planeness of longitudinal beams of composite plate beam member that erection stress can be eliminated in same plane; The purpose of the invention is to realize by following step: method for compensating planeness of longitudinal beams of composite plate beam member, and its step is as follows:
1), brushing resin on the glass fabric: select model EW100B glass fabric for use, thickness in monolayer 0.11mm selects model QY8911-II resin for use, makes EW100B/QY8911-II prepreg;
2), the prepreg laying is become blank: with thickness in monolayer is the EW100B/QY8911-II prepreg of 0.11mm, and it is the blank of 3.5mm that laying becomes thickness;
3), the blank laying of laying is being made layer of compensation on the longeron upper surface: when rail members makes up, with acetone wiping longeron surface, after the drying, with the blank laying of laying on the longeron upper surface;
4), solidify: blank and the rail members of laying on the longeron upper surface combined encapsulation, solidifies;
5), processing layer of compensation: with milling tools manual grinding or employing lathe milling: make each longeron upper surface become a plane.Milling tools is a kind of one deck sand paper of adorning on stiffening member, and sand paper often adopts No. 200.
The advantage of the invention: can use " worker " shape longeron and/or " C " shape longeron upper surface in the slab and girder spare that covering spare that composite material makes and longeron spare constitute to be in same plane and can to eliminate erection stress, improve life of product.

Among the figure: 1, milling tools 2, layer of compensation
The specific embodiment: method for compensating planeness of longitudinal beams of composite plate beam member, its step is as follows:
1), brushing resin on the glass fabric: select model EW100B glass fabric for use, thickness in monolayer 0.11mm selects model QY8911-II resin for use, makes EW100B/QY8911-II prepreg; Selected model QY8911-II resin is and makes the identical resin of longeron.
2), the prepreg laying is become blank: with thickness in monolayer is the EW100B/QY8911-II prepreg of 0.11mm, and it is the blank of 3.5mm that laying becomes thickness.
3), the blank laying of laying is being made layer of compensation on the longeron upper surface: when rail members makes up, with acetone wiping longeron surface, after the drying, with the blank laying of laying on the longeron upper surface.
4), solidify: blank and the rail members of laying on the longeron upper surface combined encapsulation, solidifies.
5), processing layer of compensation: with milling tools manual grinding or employing lathe milling: make each longeron upper surface become a plane.The lathe milling can be adopted digital control milling.
Solidify and adopt conventional curing technology.
