Abstract
A pipeless type wedge force anchor bolt belongs to a bulging bolt used in the architecture, the decorate ornament, the equipments assembly field, which comprises a cap nut, a cushion ring, a bolt and a wedge force sheet, wherein one end of the bolt has screw thread while the other end and the cylinder face of the middle portion are arranged with 1 to 6 grooves with a shaft cross section of wedge-shaped, the big end of the grooved are all arranged near the screw thread side, each of the grooves is provided with 2 to 4 wedge force sheets which are fixed with the bolt in the way which makes the wedge force sheets and the bolt be easy to move relative to each other, the wedge force sheet is tile type with a shaft cross section of wedge-shaped, the excircle cylinder of the wedge force sheet is provided with barb lengths with the same direction as the wedge-shaped direction. The utility model has the advantages of stable bulging force, big capability of bearing moving load with self-lock ability, fixing connection with uneasy loose property, small requested borehole size, and small damage for the foundation.
Description
(1), technical field
The utility model relates to the EXPANSION ANCHOR BOLTS that a kind of building, decoration, equipment installing area are used.
(2), background technique
At present the structure of the Tube type expanded bolt that uses comprises nut, packing ring, bolt and expand tube, its expansive force from the bolt circle conehead with the expand tube distending, owing to be that line contacts with being connected the basis, surface of contact is little, so bear the dynamic load ability, and do not have self-lock ability, it is fixing not firm to cause.Because the outside dimension of expand tube is big, and is so the bore size of Yao Qiuing is big in use, big to the destruction on basis.
(3), summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of pipe free wedge power crab-bolt, and it is big that it not only bears the dynamic load ability, has self-lock ability, and the bore size that requires is little, and is little to the destruction on basis.
The technical scheme in the invention for solving the technical problem is: it comprises nut, packing ring, bolt and wedge force plate, one end of bolt has screw thread, it is the groove of wedge type that 1～6 shaft section is arranged on the cylndrical surface at the other end and middle part, the groove major part is all near whorl side, be placed with 2～4 wedge force plates in each groove, adopting between wedge force plate and the bolt to make the mode that is easy to generate relative movement between the two fix, wedge force plate is a watt type, its shaft section is a wedge type, has on its external cylindrical surface and its wedge type direction hangnail always.
To the wedge force plate tension and compression, owing to be the face contact between the two, so expansive force is stable, the ability of bearing dynamic load is big, has self-lock ability, is connected firmly, and is not easy to become flexible, even break, also can not pull out from bolt for expansive force of the present utility model.Because no expand tube, so save material, radial dimension is little, and the bore size of requirement is little, and is little to the destruction on basis.
(4), description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model partial sectional view;
Fig. 2 is the utility model stereogram;
Fig. 3 is the utility model wedge force plate stereogram.
(5), embodiment
The utility model comprises nut 2, packing ring 3, bolt 1 and wedge force plate 4, as shown in drawings.One end of bolt 1 has screw thread, it is the whole circle groove of wedge type that 2 shaft sections are arranged on the cylndrical surface at the other end and middle part, the groove major part is all near whorl side, be placed with 3 wedge force plates 4 in each groove, adopt between wedge force plate 4 and the bolt 1 mode that is easy to generate relative movement between the two is fixed, for example fix with adhesive tape.Wedge force plate 4 is a watt type, and its shaft section is a wedge type, has on its external cylindrical surface and its wedge type direction hangnail 5 always, and the quantity of hangnail 5 is 1～4.
Claims (3)
1, a kind of pipe free wedge power crab-bolt, it comprises nut (2), packing ring (3), bolt (1), it is characterized in that: it also comprises wedge force plate (4), one end of bolt has screw thread, it is the groove of wedge type that 1～6 shaft section is arranged on the cylndrical surface at the other end and middle part, the groove major part is all near whorl side, be placed with 2～4 wedge force plates (4) in each groove, adopting between wedge force plate (4) and the bolt (1) to make the mode that is easy to generate relative movement between the two fix, wedge force plate (4) is a watt type, its shaft section is a wedge type, has on its external cylindrical surface and its wedge type direction hangnail (5) always.
2, wedge power crab-bolt according to claim 1 is characterized in that: it is the whole circle groove of wedge type that 2 shaft sections are arranged on the described bolt (1), is placed with 3 wedge force plates (4) in each groove.
3, wedge power crab-bolt according to claim 1 and 2 is characterized in that: fix with adhesive tape between described wedge force plate (4) and the bolt (1).
