Abstract
The utility model relates to a steel plate used by a pre-stress reinforced concrete well pipe clamp belonging to a well pipe clamp steel plate field. One side of the utility model is provided with a trough which presents a right-angled triangle section; in order to keep the thickness of the steel plate, an opposite side of the utility model is provided with a convex platform; the steel plate can form a pre-stress reinforced concrete well pipe clamp after being cut off, bended into a ring, welded and shaped; the right-angled triangle trough is used to be fixed after tensioning, therefore, the pre-stress reinforced concrete well pipe can be conveniently and fast produced.
Description
Technical field
The utility model relates to prestressed reinforced concrete well pipe hoop steel plate.
Background technology
Existing prestressed reinforced concrete well pipe hoop steel plate, the thick 8mm of general employing, wide 60mm, be made through blocking, bend operations such as circle, welding, shaping, when making the prestressed reinforced concrete well casing, fixing (saving three screws) cross section that need lathe out in appropriate location, the pipe collar outside is the right angled triangle groove easily when applying prestressed stretch-draw, and this has just increased cost of manufacture, wasted raw material, and production efficiency is low.
Summary of the invention
The utility model is exactly in order to overcome above-mentioned technical deficiency, and a kind of well pipe hoop steel plate of direct rolling and forming is provided.
For realizing the purpose of this utility model, on rolling mill, make a special roll, make the steel plate that shuts out satisfy above-mentioned requirements.
Steel plate described in the utility model is that a rolling cross section is the right angled triangle groove on former steel plate appropriate location, for keeping steel plate thickness, rolls out a boss at the steel plate offside.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is a vertical view of the present utility model.
The specific embodiment
The 1st, be steel plate.The 2nd, steel plate one lateral section is the groove of right angled triangle.The 3rd, boss.2 and 3 all is to form by special roll is rolling on the rolling mill.
Claims (1)
1. a prestressed reinforced concrete well pipe hoop steel plate is characterized in that, it is the groove of right angled triangle that there is a cross section side appropriate location, and opposite side has boss.
