The utility model has the advantages that professional customization is not needed, the processing can be carried out on site in the construction site, and the manufacture and installation are fast; all the triangular support rib plates have the same shape and single specification, and are convenient for blanking cutting and rapid welding; each triangular support rib plate is a complete steel plate, has no welding line inside and is slightly limited by construction quality; the temporary plugging device has certain popularization and application values for temporary plugging in the construction period.
Description
Technical Field
The utility model relates to a power station factory building and other draw water transfer engineering pressure steel pipe shutoff vexed head, especially be applicable to the dull and stereotyped vexed head of radiation rib formula of the interim shutoff of construction period.
Background
The pressure steel pipe is a common pipeline type of a hydropower station or other water diversion and regulation projects, temporary plugging is often needed in the construction and operation period of the pressure steel pipe, for example, a branch pipe water pressure test and the like, and the plugging means is to weld a choke plug at the end of the steel pipe or on the inner side of the pipe wall. The oval choke plug is a common choke plug form, needs to be manufactured by a professional manufacturer, and has a long manufacturing and transportation period. The flat bulkhead is convenient to manufacture and can be manufactured on site on a construction site, but the flat bulkhead can be stressed only by adding the supporting ribs behind the plate. "well" shape rib can bear great pressure, nevertheless can't intersect with great ease the rib of two directions, can only guarantee that the rib of a direction adopts complete steel sheet, and the rib of another direction is cut into a plurality of sections, welds again, and the wholeness of rib is destroyed, and welding quality receives building site construction environment, workman welding process influence great.
Disclosure of Invention
The utility model aims to provide a dull and stereotyped vexed head of radiation rib formula.
In order to achieve the above purpose, the utility model adopts the following technical proposal:
the utility model discloses a radiation rib type flat plate choke plug, which comprises a circular plate-shaped choke plug plate welded with a position to be plugged of a pressure steel pipe and a stiffening ring welded on the outer peripheral surface of the position to be plugged of the pressure steel pipe; and a plurality of right-angled triangular support rib plates are arranged and welded on the outer surface of the circular bulkhead plate along the radial direction by taking the circle center as the center, one right-angled edge of each right-angled triangular support rib plate is welded with the outer surface of the circular bulkhead plate, and the other right-angled edge of each right-angled triangular support rib plate is positioned at the outer edge of the circular bulkhead plate and is used for being welded with the inner wall of the pressure steel pipe to be plugged.
The strip-shaped steel plate is welded on the surface of the bevel edge of the right-angled triangle support rib plate and used for preventing the right-angled triangle support rib plate from being pressed, twisted and deformed.
The utility model has the advantages that the radiation rib type flat bulkhead does not need professional customization, can be processed on site in a construction site, and is fast to manufacture and install; all the triangular support rib plates have the same shape and single specification, and are convenient for blanking cutting and rapid welding; each triangular support rib plate is a complete steel plate, has no welding line inside and is slightly limited by construction quality; the temporary plugging device has certain popularization and application values for temporary plugging in the construction period.

Detailed Description
As shown in fig. 1-4, the radial rib type flat bulkhead of the present invention comprises a circular plate-shaped bulkhead 1 for welding with the position to be plugged of the penstock 2, and a stiffening ring 5 for welding on the outer peripheral surface of the position to be plugged of the penstock 2; and a plurality of right-angled triangular support rib plates 3 are arranged and welded on the outer surface of the circular plate-shaped choke plate 1 in a radial radiation manner by taking the circle center as the center, one right-angled edge of each right-angled triangular support rib plate 3 is welded with the outer surface of the circular plate-shaped choke plate 1, and the other right-angled edge of each right-angled triangular support rib plate 3 is positioned at the outer edge of the circular plate-shaped choke plate 1 and is used for being welded with the inner wall of the pressure steel pipe 2 to be plugged. The welding strength of the steel plate can be weakened by increasing the thickness of the steel plate, and the rigidity and the strength of the round plate-shaped bulkhead plate 1 are increased by the triangular support rib plates 3 under the condition that the thickness of the round plate-shaped bulkhead plate 1 is not increased, so that the round plate-shaped bulkhead plate 1 can be welded conveniently. The triangular support rib plates 3 which are uniformly distributed on the outer surface of the circular plate-shaped choke plug plate 1 in a radiation mode can increase the welding strength between the choke plug and the pressure steel pipe 2, and due to the symmetrical arrangement of the triangular support rib plates 3, the welding strength of all parts of the choke plug is the same. The triangular support rib plates 3 can enable the circular plate-shaped choke plug plate to bear larger pressure, the triangular support rib plates 3 are not crossed with each other, each triangular support rib plate 3 is complete, the integrity of the rib is guaranteed, and the construction strength is reduced. As shown in fig. 3, the stiffening ring 5 can be used to prevent the penstock 2 from being deformed by compression. Preferably, the stiffening ring 5 has one to two turns.
As shown in fig. 2, a strip steel plate 4 is welded to the surface of the hypotenuse of the right-angled triangular support rib 3 to prevent the right-angled triangular support rib 3 from being deformed by being pressed.
