Reinforced unidirectional-blocking-eave bollard

Abstract

The invention relates to a reinforced unidirectional-blocking-eave bollard used for wharves and ship locks. The reinforced unidirectional-blocking-eave bollard is provided with a base plate, a bollard body and a unidirectional-blocking eave. A plurality of anchor bolt countersinks are formed in the base plate, a top hole is formed in the top of the unidirectional-blocking eave, the bollard and the unidirectional-blocking eave are respectively of a cavity structure, the standard wall thickness of the bollard body is designed to be t, and accordingly the wall thickness of the blocking eave is 0.75t. The reinforced unidirectional-blocking-eave bollard is characterized in that a cavity of the bollard body is a conical cavity, the inner diameter D1 of a lower end opening of the cavity of the bollard body is equal to the outer diameter D-2t of the bollard body, and the inner diameter D2 of an upper end opening of the cavity of the bollard body is equal to the outer diameter D-1.5t of the bollard body. A cavity is formed in the base plate, the wall thickness of the top face of the cavity of the base plate is kept to be t, and the lateral wall thickness is larger than or equal to t. A reinforcing table is arranged at the position, located in each anchor bolt countersink, of the cavity of the base plate. The reinforced unidirectional-blocking-eave bollard overcomes the casting defects that an existing unidirectional-blocking-eave bollard is unreasonable in structural design and shrinkage, contraction cavities, cracks and the like are prone to being generated, solves the problem that material waste is high, and is mainly used in the places such as the wharves and the ship locks for ship cable mooring.

Description

technical field [0001] The invention relates to a reinforced single-sided eaves bollard for wharves and ship locks. Background technique [0002] Single-sided eaves bollards are mainly used for mooring cables in docks, locks and other places, and their strength directly relates to the safety of ships. Existing single-sided cornice bollards see figure 1 , it consists of a chassis, a column body and a single-sided eaves on the top. There is a top hole on the top of the single-sided eaves, and 6 anchor holes are opened on the chassis. The column body and the single-sided eaves are empty. Cavity structure, in the existing standard design, the column body is a cylinder structure with equal wall thickness, and its wall thickness is the standard value t (selected according to the standard GJ-33 bollard general circle set, generally 20, 30, 35 , 45, 55, 60, 70, 100, 125mm and other specifications), the thickness of the chassis is greater than the wall thickness t of the column bod...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problems of unreasonable design of the bollard bollard structure of the existing single-sided retaining eaves, easy occurrence of casting defects such as shrinkage porosity, shrinkage cavities, cracks, and large material waste, and provide an enhanced single-sided retaining eaves system ship post
