Abstract
The utility model discloses a U-shaped pipeline hoisting cross arm, and belongs to the technical field of ventilation pipelines, wherein hoisting holes are uniformly preset on the top surface of a U-shaped pipeline main body; a plurality of reinforcing rib grooves are formed at two sides of the hoisting hole and the side faces of the U-shaped pipeline main body; the tail end of the U-shaped pipeline main body is bent inwards to form an inner bent side; a spring screw is arranged in the inner cavity of the U-shaped pipeline main body; and a galvanized layer is arranged on the outer surface the U-shaped pipeline main body. The U-shaped pipeline hoisting cross arm disclosed by the utility model, through the galvanized layer on the outer surface of the main body, is smooth in surface, strong in adhesive force, corrosion resistant, durable to use, and more convenient to move and install in construction; and the bearing capability and strength of the U-shaped pipeline hoisting cross arm are improved.
Description
Technical field
The utility model belongs to the ventilator tube technical field.
Background technology
Originally U-shaped pipeline end face does not have hole for hoist when dispatching from the factory, the side is smooth side, there is no Spring screws in U-shaped inner cavity of pipe, the material of U-shaped pipeline is all black iron plate, and the problem of bringing is to move and install inconvenience when construction, and load-carrying capacity is little, intensity is low, not withstanding corrosion.
Summary of the invention
The purpose of this utility model is to provide a kind of U-shaped lifting pipeline cross-arm, moves and install inconvenience to solve prior art when the construction, and load-carrying capacity is little, and intensity is low, not the problem such as withstanding corrosion.
The utility model mainly is comprised of U-shaped pipe main body, the end face that solves technical scheme that its technical matters adopts and be U-shaped pipe main body is default hole for hoist evenly, the side of hole for hoist both sides and U-shaped pipe main body arranges some roads reinforced rib groove, the end of U-shaped pipe main body curves inwardly, form concave edge, the R of concave edge is 4.4-5mm; The inner chamber of U-shaped pipe main body arranges Spring screws; U-shaped pipe main body outside arranges zinc coating.
Adopting good effect of the present utility model is that main body outside arranges zinc coating, any surface finish, and strong adhesion, anticorrosive durable in use, move when construction and easier for installation, improved load-carrying capacity and intensity.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model birds-eye view.
1 zinc coating, 2 reinforced rib grooves, 3U type pipe main body, 4 Spring screwses, 5 concave edges, 6 holes for hoist in figure.
The specific embodiment
As shown in the figure: the evenly default three groups of holes for hoist 6 of the end face of U-shaped pipe main body 3, the side of hole for hoist 6 both sides and U-shaped pipe main body 3 respectively arranges twice reinforced rib groove 2, and the end of U-shaped pipe main body 3 curves inwardly, and forms concave edge 5, and the R of concave edge 5 is 4.6mm; The inner chamber of U-shaped pipe main body 3 arranges Spring screws 4; U-shaped pipe main body 3 outsides arrange zinc coating 1.
Claims (2)
1. U-shaped lifting pipeline cross-arm, mainly formed by U-shaped pipe main body, the end face that it is characterized in that U-shaped pipe main body is evenly preset hole for hoist, the side of hole for hoist both sides and U-shaped pipe main body arranges some roads reinforced rib groove, the end of U-shaped pipe main body curves inwardly, form concave edge, the inner chamber of U-shaped pipe main body arranges Spring screws; U-shaped pipe main body outside arranges zinc coating.
