Embodiment 1

[0016] (1) Drill holes on the U-shaped pultrusion profile

[0017] U-shaped profile 1 of glass fiber reinforced plastic (FRP) is produced by pultrusion molding (the minimum width of U-shaped profile 1 is 300mm), and two rows of holes of equal diameter are drilled on the upper and lower sides of the two flanges of 1, and the axis of the hole 20-30mm from the outer side of the web (lower side of the U-shaped profile 1). The upper row of holes is evenly distributed along the longitudinal direction of the flange of the U-shaped profile (perpendicular to the cross-sectional direction), and the hole distance is 150-300mm. The axis of the lower row of holes is 15-20mm away from the edge of the flange (the top surface of the U-shaped profile 1).

[0018] (2) Pierce the lower row of FRP bars through the holes first, and then pour concrete into the inner bottom of the U-shaped bar

[0019] Place the U-profiles 1 side by side in flat shallow water, and align the two rows of holes. Firs...

Abstract

The invention discloses a glass FRP (fiber reinforced plastic) profile combined floating raft. The combined floating raft comprises multiple U-shaped glass FRP profiles. A raft body floating on the water surface is formed by combining FRP bars and glass FRP pultruded profiles, the FRP bars are fixed through cement concrete, and larger raft pieces can be made on the water side or the water surface.The raft pieces contain no metal, and therefore, rusting cannot be caused. The concrete is pressed at the bottom of the raft body, and the bottom weight is increased, so that the raft body is more stable in water; multiple layers of fabric meshes are laid in concrete at connecting joints, accordingly, the area of the raft cannot be limited by the length of the U-shaped profiles, and the larger-size floating raft can be made in water.

Description

technical field [0001] The invention relates to the technical field of manufacturing floating rafts or floating bridges, in particular to a floating raft composed of glass fiber reinforced plastic profiles. Background technique [0002] The fiberglass raft molded by the factory is used. If the volume is large, it will be inconvenient to transport. At present, the floating rafts assembled on the water surface of small glass fiber reinforced plastic boxes are made of separate parts, the integrity of the water surface assembly is poor, and the splicing method is not strong enough to withstand the impact of wind and waves. [0003] To sum up, it is an urgent technical problem in this field to provide a strong and durable floating raft that can be assembled by a large area of ​​water by using FRP pultruded profiles. Contents of the invention [0004] The object of the present invention is to provide a kind of solid and durable floating raft that can be assembled in a large are...
