Reinforced bollard with bidirectional-blocking eave

Abstract

The invention relates to a reinforced bollard with a bidirectional-blocking eave, wherein the reinforced bollard is used for wharves and ship locks. The reinforced bollard with the bidirectional-blocking eave is provided with a base plate, a bollard body and the bidirectional-blocking eave. A plurality of anchor bolt countersinks are formed in the base plate, a top hole is formed in the top of the bidirectional-blocking eave, the part of the bollard body and the part of the bidirectional-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 part of the blocking eave is 0.75t. The reinforced bollard with the bidirectional-blocking eave 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 bollard with the bidirectional-blocking eave overcomes the casting defects that an existing bollard with a bidirectional-blocking eave is unreasonable in structural design and shrinkage, contraction cavities, cracks and the like are prone to being generated, solves the problem that the existing bollard with the bidirectional-blocking eave is high in material waste, 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 bollard with double eaves for wharves and ship locks. Background technique [0002] The bollard with double eaves is mainly used for mooring cables of ships in docks, locks and other places, and its strength is directly related to the safety of ships. Existing double cornice bollards see figure 1 , it consists of a chassis, a column body and a double eaves on the top. The top of the double eaves is provided with a top hole, and there are 6 anchor holes on the chassis. The column body and the double eaves are cavity structures. In the existing standard design, the column body is a cylindrical 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, etc.), the thickness of the chassis is greater than the wall thickness t of the column body, and the wall thickness of the ...
