Abstract
The utility model discloses a steel structure bolt for a megawatt unit boiler. The steel structure bolt comprises a hexagonal head, a reinforcing rib and a screw rod, wherein the hexagonal head and the screw rod are molded integrally; the reinforcing rib is welded at the joint between the hexagonal head and the screw rod; and the front section of the screw rod is provided with a threaded section. The steel structure bolt for the megawatt unit boiler has higher intensity, and can be screwed repeatedly.
Description
Technical field
The utility model relates to a kind of bolt, particularly a kind of million kilowatt unit boiler steel structure bolt.
Background technique
Steel structure bolt is a series products important in the high-intensity fasteners, and the frictional that is mainly used in electric power system, mechanical industry, steel-structure factory building and boiler steelframe, railroad bridge, harbour machinery, tall building, longspan civil building, tower mast structure and other Steel Structure Works is connected.But the bolt strength that existing million kilowatt unit boiler is used is not enough, and some bolts of early tightening owe stubborn, can't carry out twisting again, and dismantle also very difficult.
The model utility content
Technical problem to be solved in the utility model provides a kind of million kilowatt unit boiler steel structure bolt, and it improves intensity, and can carry out twisting again.
For solveing the technical problem, the utility model provides a kind of million kilowatt unit boiler steel structure bolt, it is characterized in that, it comprises hexagon head, stiffening rib, screw rod, hexagon head and screw rod are one-body molded, stiffening rib is welded on the joint of hexagon head and screw rod, and the leading portion of screw rod is provided with thread section.
Positive progressive effect of the present utility model is: the utility model million kilowatt unit boiler improves intensity with steel structure bolt, and can carry out twisting convenient disassembly again.
Description of drawings
Fig. 1 is the utility model one embodiment's a structural representation.
Embodiment
Lift a preferred embodiment below, and come the clearer the utility model that intactly illustrates in conjunction with the accompanying drawings.
As shown in Figure 1, the utility model million kilowatt unit boiler comprises hexagon head 1, stiffening rib 2, screw rod 3 with steel structure bolt, hexagon head 1 and screw rod 3 are one-body molded, stiffening rib 2 is welded on the joint of hexagon head 1 and screw rod 3, can improve intensity like this, the leading portion of screw rod 3 is provided with thread section 4, the length of thread section 4 be screw rod 3 entire length 1/3rd to 1/2nd, fixed effect is better like this.Because the existence of hexagon head 1, can carry out twisting again with wrest fixing spanner, convenient disassembly has been avoided that the job site condition is poor, understanding is not enough and has been caused the problem of once twisting eventually.
Though more than described embodiment of the present utility model, but those skilled in the art is to be understood that, these only illustrate, and under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these mode of executions.Therefore, protection domain of the present utility model is limited by appended claims.
