The utility model discloses simple structure, the preparation is easy, and compressive capacity is strong, and intensity is high, owing to be equipped with the strengthening rib at the slot part to increase the moment of torsion, reduced the diameter of screw rod and extension rod, saved the material, the cost is reduced.
Description
Technical field
This utility model relates to steel construction technical field of fastening, has particularly related to a kind of high strength steel structural bolts.
Background technology
At present, domestic be widely used in industry all adopt steel construction torsional shear type bolt to be connected with civil buildings, bridge, pylon, support of pipelines, hoisting machinery and other steel construction friction-type connections.Existing steel construction torsional shear type bolt ubiquity intensity is low, and degree of firmly installing is not high, causes steel construction stability to reduce, there is certain potential safety hazard, meanwhile, moment of torsion is subject to the restriction of the diameter of bolt, when needing high pulling torque, being necessary for increasing accordingly the diameter of screw rod, cost increases.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is that and provides a kind of high strength steel structural bolts, and intensity is high, and cost is low, and moment of torsion is bigger, and compressive property is strong.
To achieve these goals, the technical solution adopted in the utility model is such that a kind of high strength steel structural bolts, and including screw rod, bolt head and elongation bar, one end of described screw rod is connected with bolt head, the other end is connected with elongation bar；Described screw rod is provided with external screw thread near one end of elongation bar, and is provided with the groove being positioned at screw rod outer surface between external screw thread and bolt head；It is provided with groove portion between described elongation bar and screw rod, in this groove portion, is evenly distributed with reinforcement.
As a kind of preferred version, described screw rod is hollow form.
As a kind of preferred version, the cross section of described groove is indent rectangle, and its length is 1/4th of spiro rod length.
As a kind of preferred version, described bolt head is hexagonal bolt head.
As a kind of preferred version, the junction of described bolt head and screw rod adopts round-corner transition, and the radius of this fillet is 1 ~ 2mm.
As a kind of preferred version, the junction of described bolt head and screw rod is provided with flange.
As a kind of preferred version, described flange includes ring flange and flange center's pipeline；Described ring flange is integral with flange center's pipeline welding, and is provided with flange reinforcing ribs between ring flange and flange center's pipeline；Described flange reinforcing ribs is uniformly distributed on ring flange, and the adjacent ring flange between flange reinforcing ribs is provided with screw.
Compared with prior art, the beneficial effects of the utility model: this utility model simple in construction, make easily, anti-pressure ability is strong, intensity is high, owing to being provided with reinforcement in groove portion, thus adding moment of torsion, reduce screw rod and the diameter of elongation bar, save material, reduce cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of flange in this utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is further described.Following example are only for clearly illustrating the technical solution of the utility model, and can not limit protection domain of the present utility model with this.
Embodiment:
As it is shown in figure 1, a kind of high strength steel structural bolts, including screw rod 1, bolt head 2 and elongation bar 3, one end of described screw rod 1 is connected with bolt head 2, the other end is connected with elongation bar 3；Described screw rod 1 is provided with external screw thread 4 near one end of elongation bar 3, and is provided with the groove 5 being positioned at screw rod 1 outer surface between external screw thread 4 and bolt head 2；It is provided with groove portion 6 between described elongation bar 3 and screw rod 1, in this groove portion 6, is evenly distributed with reinforcement 7.
The preferred described screw rod 1 of this utility model is in hollow form so that it is becoming flexible bolt, when receiving shock and vibration, deflection is big, absorbs energy strong so that its intensity improves.
The cross section of the preferred described groove 5 of this utility model is indent rectangle, and its length is 1/4th of screw rod 1 length.By the groove 5 of setting during enforcement, reduce the integral rigidity of bolt, improve the pliability of bolt, bolt is made can effectively to absorb passive shock wave, decrease and bear operating horizontal and vertical vibrational loading, the indent rectangular cross sectional shape of groove 5, improves the heavy burden load-carrying ability that bolt bears.
The preferred described bolt head 2 of this utility model is hexagonal bolt head, relative to existing circular bolt head, more anti-skidding, is easy for installation and removal, decreases the working time of operator, improve work efficiency.
The junction of the preferred described bolt head 2 of this utility model and screw rod 1 adopts round-corner transition, and the radius of this fillet is 1 ~ 2mm, it is possible to reduce stress concentration phenomenon, further increases bolt strength.
The junction of the preferred described bolt head 2 of this utility model and screw rod 1 is provided with flange 8.
As in figure 2 it is shown, described flange 8 includes ring flange 81 and flange center's pipeline 82；Described ring flange 81 is integrally welded with flange center's pipeline 82, and is provided with flange reinforcing ribs 83 between ring flange 81 and flange center's pipeline 82；Described flange reinforcing ribs 83 is uniformly distributed on ring flange 81, and the adjacent ring flange 81 between flange reinforcing ribs 83 is provided with screw 84.Compared with existing circular configuration flange, this utility model adopts orthohexagonal flange 8, and is provided with flange reinforcing ribs 83, and anti-pressure ability is strong.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the premise without departing from this utility model know-why; can also making some improvement and deformation, these improve and deformation also should be regarded as protection domain of the present utility model.
