Problems solved by technology

At present, steel structure casings are mostly used around the caps, such as: Hangzhou Bay Bridge. When a ship hits the anti-collision device of the steel casing, the outer structural steel plate of the anti-collision structure undergoes large deformation, absorbing part of the collision energy, but The cost of the steel casing is relatively high; and the steel casing usually withstands a single impact, and it is difficult to repair after the collision; at the same time, the hull is easily damaged during the collision; in addition, the steel is easy to rust in the water all year round, and the maintenance cost is high

example 1

[0032] In the composite material bridge anti-collision column of the present invention, the shell is a composite material surface layer 1 formed by curing glass fiber and vinyl resin, and adopts Paulownia wood core material 2 to form a composite material sandwich structure shell, and the cross section of the shell is semicircular D-shaped. Prepared by vacuum introduction process, using flanges and bolts 4 to combine the D-shaped shell and the flat shell to form a closed composite shell; the interior of the composite shell is filled with moso bamboo 3 arranged horizontally; the anti-collision columns are spaced at a certain distance around the rectangular cross-section pier fixed.

example 2

[0034] The composite material bridge anti-collision column of the present invention, the outer shell is a composite material surface layer 1 cured by basalt fiber and epoxy resin, which constitutes a composite material laminate shell, the cross section of the shell is box-shaped, and chamfering is provided, and a vacuum introduction process is adopted For preparation, use flanges and bolts 4 to combine the box-shaped shell and the flat shell to form a closed composite shell; the interior of the composite shell is filled with polyurethane foam 3, and the anti-collision column is fixed on the shore of the dock.

example 3

[0036] The composite material bridge anti-collision column of the present invention, the shell is a composite material surface layer 1 formed by curing glass fiber and unsaturated polyester resin, and adopts Paulownia wood core material 2 to form a composite material sandwich structure shell; the interior of the composite material shell is filled and recycled The rubber particles 3 constitute the anti-collision column, and the anti-collision column is fixed around the offshore oil production platform.

[0037] The manufacture method of composite bridge anti-collision column of the present invention is as follows:

[0038] a. First prepare a set of large-scale wood or fiberglass molds, and adopt a vacuum introduction process on the mold to prepare the glass fiber / vinyl resin 1 composite anti-collision system shell 5 with Paulownia wood as the sandwich material 2;

[0039] b. Arranging moso bamboo 3 closely and horizontally inside the composite material shell 5, and filling the ...

Abstract

The invention relates to a bridge bearing platform composite material collision post, comprising a composite material shell (5); the bridge bearing platform composite material collision post is characterized in that: the vertical wall of the composite material shell (5) is composed of a composite material surface layer (1), a sandwich material layer (2) and a resin based fiber sandwich composite material inner layer (6), the sandwich material layer (2) is clamped between the composite material surface layer (1) and the resin based fiber sandwich composite material inner layer (6), a filling material layer (3) is filled in the composite material shell (5), mounting ears (7) are formed by respectively extending to two sides, facing to one surface of the bridge bearing platform, a mounting hole (4) which is used for being penetrated by a bolt to fix the collision post on the bridge bearing platform is arranged on the mounting ear (7); the bridge bearing platform composite material collision post has simple structure, reliable and perfect anti-collision function and long service life, and is convenient for maintenance and repair.

Description

[0001] The invention applied for a utility model patent on the same day. technical field [0002] The invention relates to a bridge protection article, especially an anti-collision article suitable for all kinds of bridge caps, wharves, and water (ocean) buildings to reduce the collision disaster of ships (ice floes). The composite anti-collision column of the bridge cap made of recycled materials. Background technique [0003] As we all know, the caps of bridges generally meet the anti-collision requirements in structural design, but at low navigable water levels, in order to protect ships, especially when the underwater spherical head collides with the caps, due to the steel plate and concrete bearing Taiwan is a "head-to-head", and ships are prone to serious damage. At present, steel structure casings are mostly used around the caps, such as: Hangzhou Bay Bridge. When a ship hits the anti-collision device of the steel casing, the outer structural steel plate of the anti-...
