Embodiment Construction

[0050] see figure 2-5, the present invention has a chassis 1, a column body 3 and a full eaves 4, on the chassis 1 there are several anchor bolt sink holes 2, the top of the full eaves 4 has a top hole 5, the column body 3 and the whole eaves The retaining eaves 4 is a cavity structure, the design standard wall thickness of the column body 3 is t=30mm, then the wall thickness t1 of the full retaining eaves 4 is 22.5mm, especially: the cavity of the column body 3 is a conical cavity, and the column body 3 The inner diameter of the lower port of the cavity D1= 250-60=190mm (the outer diameter D of the column body can be checked as 250mm by the standard), and the inner diameter of the upper port of the cavity 3 of the column body D2=250-45=205mm; a cavity is opened on the chassis 1 , keep the top wall thickness t3=30mm of the chassis cavity 7, and the side wall thickness t2=30-35mm, specifically 35mm. The junction of the chassis cavity 7 and the column body cavity adopts a larg...

Abstract

The invention relates to a reinforced full-blocking-eave bollard used for wharves and ship locks. The reinforced full-blocking-eave bollard is provided with a base plate, a bollard body and a full-blocking eave. A plurality of anchor bolt countersinks are formed in the base plate, a top hole is formed in the top of the full-blocking eave, the bollard and the full-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 full-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 full-blocking-eave bollard overcomes the casting defects that an existing full-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 bollard with full eaves for wharves and ship locks. Background technique [0002] The bollard with full eaves is mainly used for mooring cables of ships in docks, locks and other places, and its strength directly relates to the safety of ships. Existing full eaves bollard see figure 1 , it consists of a chassis, a column body and a full eaves on the top. There are top holes on the top of the full eaves, and 6 anchor holes are opened on the chassis. The column body and the full 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 full retaining eaves p...
