Abstract
The invention discloses a kind of steel pipe flange valve snail bolt female connection structure, comprise large diameter steel pipe, Large-diameter Steel pipe flange, minor-diameter steel-tube, minor-diameter steel-tube flange and bolt; Described large diameter steel pipe docks with minor-diameter steel-tube, is bolted between Large-diameter Steel pipe flange and minor-diameter steel-tube flange; Described Large-diameter Steel pipe flange offers internal thread hole, aperture is mated with the described diameter of bolt, described minor-diameter steel-tube flange offers bolt hole, aperture 1.5 ~ 2mm larger than the described diameter of bolt, described bolt is through the bolt hole on minor-diameter steel-tube flange, and tighten in the internal thread hole on screw-in Large-diameter Steel pipe flange, bolt length exposes Large-diameter Steel pipe flange two screw threads.Structure of the present invention does not need nut, and reduce the requirement of large diameter steel pipe flange plate bolt back gauge, directly tight a bolt a joint steel pipe flange.
Description
Technical field
The present invention relates to the accessory used in a kind of building structure, be specifically related to a kind of steel pipe flange valve snail bolt female connection structure.
Background technology
Existing steel pipe flange dish connects to meet bolt construction requirement, bolt needs certain back gauge requirement from steel pipe walls, when the steel pipe flange dish that external diameter is different connects, the flange overhanging width of minor-diameter steel-tube is larger, greatly reduce coupling stiffness, ensure that coupling stiffness certainly will increase flange thickness, cause waste of material, increase cost.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of steel pipe flange valve snail bolt female connection structure, this structure does not need nut, and reduce the requirement of large diameter steel pipe flange plate bolt back gauge, directly tight a bolt a joint steel pipe flange.
The present invention is by the following technical solutions: a kind of steel pipe flange valve snail bolt female connection structure, comprises large diameter steel pipe, Large-diameter Steel pipe flange, minor-diameter steel-tube, minor-diameter steel-tube flange and bolt;
Described large diameter steel pipe docks with minor-diameter steel-tube, is bolted between Large-diameter Steel pipe flange and minor-diameter steel-tube flange;
Described Large-diameter Steel pipe flange offers internal thread hole, aperture is mated with the described diameter of bolt, described minor-diameter steel-tube flange offers bolt hole, aperture 1.5 ~ 2mm larger than the described diameter of bolt, described bolt is through the bolt hole on minor-diameter steel-tube flange, and tighten in the internal thread hole on screw-in Large-diameter Steel pipe flange, bolt length exposes Large-diameter Steel pipe flange two screw threads.
As preferably, when adopting high-strength bolt, tightening and making to produce prestressing force in high-strength bolt.
The present invention does not need bolt nut, and Large-diameter Steel pipe flange bores tapped bolt hole, and on minor-diameter steel-tube flange, auger shell keyhole, tights a bolt, and realizes the connection of two steel pipe flange dishes.
The present invention can be used for, in the connection of different diameter of steel tube flange, can being widely used in various steel tubular structure.
Beneficial effect of the present invention: when different-diameter steel pipe is connected by flange, the back gauge requirement of internal thread hole not demand fulfillment bolt construction on Large-diameter Steel pipe flange, thus reduce the diameter of flange, save material, improve flange coupling stiffness, connect simultaneously and do not need nut, can link cost be saved.

Fig. 2 is large diameter steel pipe flange plate structure schematic diagram of the present invention;
Fig. 3 is minor-diameter steel-tube flange plate structure schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with detailed description of the invention and accompanying drawing, the present invention will be further described:
As shown in Figure 1,2 and 3, a kind of steel pipe flange valve snail bolt female connection structure, comprises large diameter steel pipe 1, Large-diameter Steel pipe flange 2, minor-diameter steel-tube 3, minor-diameter steel-tube flange 4 and bolt 5;
Described large diameter steel pipe 1 docks with minor-diameter steel-tube 3, is connected between Large-diameter Steel pipe flange 2 with minor-diameter steel-tube flange 4 by bolt 5;
Described Large-diameter Steel pipe flange 2 offers internal thread hole 7, aperture and described bolt 5 diameter matches, described minor-diameter steel-tube flange 4 offers bolt hole 6, aperture 1.5 ~ 2mm larger than described bolt 5 diameter, described bolt 5 is through the bolt hole 6 on minor-diameter steel-tube flange 4, and tighten in the internal thread hole 7 on screw-in Large-diameter Steel pipe flange 2, bolt 5 length exposes Large-diameter Steel pipe flange 2 two screw threads.When adopting high-strength bolt, tightening and making to produce prestressing force in high-strength bolt.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
