Description
Technical Field
The invention relates to the technical field of anchoring, in particular to a threaded-head anchor bolt.
Background
The anchor bolt is a general term of all rear anchoring components and is an anchoring component for anchoring a connected piece to a base material such as concrete. The main stream of mechanical anchor bolts at present is rear expanding bottom anchor bolts, self-cutting bottom anchor bolts, cement self-tapping anchor bolts, Anka anchor bolts, heavy anchor bolts and the like. The screw thread of the concrete self-tapping anchor bolt is directly meshed with the wall of the concrete hole tightly, so that the damage of a cone of the base material concrete is avoided, and the stress is dispersed, thereby ensuring high bearing capacity and being suitable for small-margin and small-space installation.
The structural requirements in Standard TB/T3440 leaky coaxial cable hanger for railway communication are as follows: the spreader in the tunnel should have a wall-to-wall mounting structure and the minimum vertical distance between the surface of the leaky cable and the tunnel wall should not be less than 80 mm. However, in order to ensure the load-bearing capacity, it is necessary to ensure the anchor bolt is buried deep, so that the fixture after being mounted on the anchor bolt often cannot meet the required wall-to-wall distance.
Disclosure of Invention
The technical problem solved by the invention is as follows: the invention provides a screw head anchor bolt which can meet the requirement of off-wall installation.
The technical scheme of the invention is as follows: the utility model provides a screw thread head crab-bolt, includes screw rod and the head that the tip links to each other, be provided with the screw thread section on the screw rod, the head with one side that the screw rod is relative is provided with the screw thread head, and the screw thread section anchor is on the building, through the fixed fixture of screw thread head or other parts that need be fixed, the setting of screw thread head has increased the distance between fixture or other parts and the building, can satisfy its installation requirement.
Furthermore, the screw thread section comprises screw threads arranged at equal intervals, a V-shaped arc groove is formed between the screw threads, and the V-shaped arc groove is matched with the screw threads to enable the anchor bolt to be cut into the building more easily.
Furthermore, being close to be provided with the breach on the thread of screw thread section tip, the frictional force of crab-bolt and building has been reduced in the setting of breach, and simultaneously, the breach can hold the smear metal, and can be with the leading-in V-arrangement arc inslot of smear metal for the crab-bolt is changeed and is cut into in the building.
Further, the notch is a V-shaped groove.
Furthermore, the notches of the adjacent threads are staggered, so that chips entering from the two notches between the adjacent threads are prevented from blocking the V-shaped arc groove.
Furthermore, the head is provided with convex teeth on the end surface of one side close to the screw rod, and the convex teeth can ensure that a certain friction force exists between the head of the anchor bolt and a building, but the friction force is not too large, so that the anchoring force of the anchor bolt is increased.
Further, the convex teeth are arranged around the center line of the head in an involute shape, so that the friction direction between the convex teeth and a building is opposite to the screwing direction of the anchor bolt, and the anchor bolt is not easy to loosen.
Further, the convex teeth are of arc-sheet structures.
Compared with the prior art, the invention has the advantages that: the threaded head is arranged on one side, opposite to the screw, of the head and used for fixing a fixture or other parts needing to be fixed, and the distance between the fixture or other parts and a building is increased due to the arrangement of the threaded head, so that the mounting requirements of the fixture or other parts can be met.
Drawings
Fig. 1 is a view showing the construction of an anchor bolt of the present invention.
Reference numerals:
the screw comprises a screw 1, a thread section 11, a notch 11, a thread 12, a V-shaped arc groove 13, a head 2, a convex tooth 21 and a thread head 3.
Detailed Description
The invention is further illustrated by the following examples in conjunction with the accompanying drawings:
in order to enable the fixture to meet the requirement of wall-separated installation after being installed on the anchor bolt, the applicant designs a threaded-head anchor bolt.
The threaded-head anchor bolt is a self-tapping anchor bolt and specifically comprises a screw rod 1 and a head 2 which are connected at the ends, wherein a threaded section 11 is arranged on the screw rod 1, a threaded head 3 is arranged on one side of the head 2 opposite to the screw rod 1, and the threaded head 3, the screw rod 1 and the head 2 are coaxially arranged so as to ensure that the force borne by the anchor bolt after a clamping apparatus for clamping a cable is installed on the screw rod 1, thereby ensuring the connection reliability of the anchor bolt.
Specifically, screw thread section 11 includes the screw thread 12 that the equidistance set up, and is adjacent form the arc wall between the screw thread 12, and is preferred, and this arc wall is V-arrangement arc wall 13, and V-arrangement arc wall 13 can make the smear metal change and fall into its tank bottom to the better chip removal.
Preferably, notches 11 are formed in a plurality of screw teeth 12 close to the end portion of the threaded section 11, the notches 11 are arranged at equal intervals along the rotation track of the screw teeth 12, and the number of the screw teeth 12 with the notches 11 is determined according to specific anchor bolt burial depth requirements and the like. Preferably, the notch 11 is a V-shaped groove, and the notch 11 is configured to reduce friction between the thread 12 and the building during the anchoring process, so that the thread section 11 of the anchor bolt can be cut into the building more easily.
Preferably, the notches 11 of adjacent threads 12 are offset to prevent chips entering from the two notches 11 between adjacent threads 12 from blocking the V-shaped arc groove 13, thereby making the anchor bolt easier to cut into the building.
Preferably, the end surface of the head 2 close to the screw 1 is provided with a convex tooth 21, and the convex tooth 21 plays the same role as a gasket to a certain extent, and the installation is simple and convenient without adding parts.
Preferably, the convex teeth 21 are of an arc-sheet structure, so that the anchor bolt can be anchored firmly, and meanwhile, the friction force between the convex teeth 21 and a building is large when no gasket is used, and the anchor bolt is convenient to disassemble.
Preferably, the dogtooth 21 centers on the central line of head 2 is arranged in the involute form, makes the frictional force direction between dogtooth 21 and the building opposite with the tightening direction of crab-bolt, increases the occlusal force between crab-bolt and the building to make the difficult not hard up of crab-bolt.
Those skilled in the art will appreciate that those matters not described in detail in the present specification are well known in the art.
