Problems solved by technology

However, the production cost of FRP components is relatively high, and the production cost of molds required for FRP components with different structural shapes is also high, and the size of FRP components is limited by the size of the mold required for making FRP components. The manufacturing method of a kind of FRP member is particularly important

Embodiment Construction

[0028] The invention is attached Figure 1-41 shown.

[0029] The manufacturing method of this ribbed FRP component comprises the following steps: the first step is to make the FRP basic block, and its structural form is as follows: figure 1 , Figure 6-29 , Figures 31 to 32 , Figures 34 to 38 shown. The FRP basic block 1 is divided into two parts: the lower FRP basic bottom plate 1.1 and the upper FRP basic longitudinal rib 1.2, at least one of the FRP basic bottom plate 1.1 and the FRP basic longitudinal rib 1.2 adopts a hollow section form. Figure 1-28 It is a structural schematic diagram of the FRP basic block 1 composed of the FRP basic bottom plate 1.1 in the form of a hollow section and the basic longitudinal plate rib 1.2 of the FRP in the form of a solid section; Figures 29 to 31 It is a structural schematic diagram of an FRP basic block 1 composed of an FRP basic base plate 1.1 in the form of a solid section and a basic FRP longitudinal plate rib 1.2 in the ...

Abstract

The invention discloses a manufacturing method for ribbed FRP members. The method comprises the following steps: manufacturing basic FRP splicing blocks; forming bolt holes in the basic FRP splicing blocks; placing the basic FRP splicing blocks according to a certain sequence, and mounting bolts or end bolts in the bolt holes of the adjacent basic FRP splicing blocks; regularly arranging glue injection nozzles in gaps between the adjacent basic FRP splicing blocks, and performing edge sealing processing for the peripheries of the gaps at splicing positions of the adjacent basic FRP splicing blocks; injecting glue into the gaps in the splicing positions of the adjacent basic FRP splicing blocks through the glue injection nozzles; after the glue is solidified, dismantling or retaining the bolts and end bolts; after the glue is fully solidified and reach a certain strength, forming horizontal through holes in FRP longitudinal plate ribs formed by the adjacent basic FRP splicing blocks. The ribbed FRP members in size is not limited by sizes of the basic FRP splicing blocks, and can be freely spliced according to the actual size required by the construction site, so that the advantages that manufacturing and construction are simple and convenient, the construction speed is fast, the structural mechanics performance is excellent and the economic performance is considerable are achieved.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, and in particular relates to a manufacturing method of a ribbed FRP component. Background technique [0002] In the application field of civil engineering technology, fiber reinforced plastics (hereinafter referred to as FRP) are favored because of their high strength, low surface density, good fatigue resistance and corrosion resistance, among which FRP bridge decks are particularly valued. According to the material composition, the FRP bridge deck can be divided into full FRP bridge deck and FRP-concrete composite bridge deck. However, the price of FRP materials is higher than that of steel and concrete. The full FRP bridge deck has disadvantages such as large initial investment, low stiffness, and difficulty in connecting with the main girder. , has not been widely used. Patent 201320209441.3 discloses a composite bridge deck with ribbed FRP members and concrete. The bridge deck ma...
