Abstract
The utility model discloses a device of reinforcing built-in fitting resistance to plucking force, including the screw-thread steel sleeve, the one end of screw-thread steel sleeve is equipped with the internal thread hole, and the other end of screw-thread steel sleeve is the reinforcing bar insertion section, and the cover is equipped with the resistance to plucking sleeve on the reinforcing bar insertion section of screw-thread steel sleeve, has all seted up the through-hole on resistance to plucking sleeve and the screw-thread steel sleeve, and it is fixed that the through-hole passes through the bolt with the screw-thread steel sleeve, and the resistance to plucking sleeve is kept away from one of the reinforcing bar insertion section. The utility model discloses a take resistance to plucking muffjoint of ring piece is on the reinforcing bar, and the reuse bolt is perforated fixedly resistance to plucking sleeve and threaded steel sleeve. Because the contact area of the ring piece is large, the pulling resistance can be effectively increased, the bolt connection is convenient, and the welding deformation is reduced.
Description
Technical Field
The utility model relates to a building built-in fitting technical field especially relates to a device of reinforcing built-in fitting withdrawal resistance.
Background
The threaded steel sleeve is a common embedded part on a PC component and mainly used for installing a bolt and a hanging ring. In the hoisting, transportation and fixation of the member, the threaded steel sleeve is a node bearing direct tensile force, so the pulling resistance is a key performance index of the embedded part.
As shown in fig. 1 and 2, a conventional method for enhancing the pulling resistance of the threaded steel sleeve 1 generally includes drilling a hole 9 in the bottom of the threaded steel sleeve 1, and then inserting and welding a reinforcing steel bar 10. The method is simple, but the section of the dowel bar is small, the contact area with concrete is small, and the increased uplift resistance is limited.
SUMMERY OF THE UTILITY MODEL
In order to solve the above-mentioned drawbacks, an object of the present invention is to provide a device for enhancing the anti-pulling force of the embedded part, which has a simple structure and can effectively enhance the anti-pulling force and reduce the welding deformation.
In order to achieve the above object, the utility model discloses a following technical scheme realizes: the utility model provides a device of reinforcing built-in fitting withdrawal resistance, includes threaded steel sleeve, threaded steel sleeve's one end is equipped with the internal thread hole, threaded steel sleeve's the other end is reinforcing bar insertion section, the cover is equipped with the resistance to plucking sleeve on the reinforcing bar insertion section of threaded steel sleeve, the through-hole has all been seted up on resistance to plucking sleeve and the threaded steel sleeve, it is fixed that the through-hole passes through the bolt with threaded steel sleeve, the resistance to plucking sleeve is kept away from one of the reinforcing bar insertion section of threaded steel sleeve and is served and be equipped with the ring piece.
Furthermore, the threaded steel sleeve is provided with an anti-skid surface.
Furthermore, the through hole in the anti-pulling sleeve and the through hole in the threaded steel sleeve are perpendicular to the axis of the threaded steel sleeve.
Furthermore, a plurality of bulges are uniformly arranged on the anti-skid surface.
The utility model has the advantages that: the anti-pulling sleeve with the ring piece is sleeved on the steel bar, and then the anti-pulling sleeve and the threaded steel sleeve are fixed by the bolt through hole. Because the contact area of the ring piece is large, the pulling resistance can be effectively increased, the bolt connection is convenient, and the welding deformation is reduced.

Wherein: 1. the steel bar anti-pulling device comprises a threaded steel sleeve, 2, an internal threaded hole, 3, a steel bar insertion section, 4, an anti-pulling sleeve, 5, a bolt, 6, a circular ring piece, 7, an anti-sliding surface, 8, a protrusion, 9, a hole, 10 and steel bars.
Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 3 and 4, the device for enhancing the anti-pulling force of the embedded part comprises a threaded steel sleeve 1, wherein one end of the threaded steel sleeve 1 is provided with an internal threaded hole 2, and the other end of the threaded steel sleeve 1 is a steel bar insertion section 3. The steel bar insertion section 3 of the threaded steel sleeve 1 is sleeved with an anti-pulling sleeve 4, through holes 9 are formed in the anti-pulling sleeve 4 and the threaded steel sleeve 1, the anti-pulling sleeve 4 and the threaded steel sleeve 1 penetrate through the through holes through bolts 5 to be fixed, and one end, far away from the steel bar insertion section 3 of the threaded steel sleeve 1, of the anti-pulling sleeve 4 is provided with a circular ring piece 6.
The threaded steel sleeve 1 is provided with an anti-skid surface 7. A plurality of bulges 8 are evenly arranged on the anti-skid surface 7. The anti-slip surface 7 increases the contact area and the friction force between the threaded steel sleeve 1 and the PC component, and contributes to enhancing the anti-pulling force.
The through hole on the anti-pulling sleeve 4 and the through hole on the threaded steel sleeve 1 are perpendicular to the axis of the threaded steel sleeve 1.
The utility model discloses a take resistance to plucking muffjoint of ring piece is on the reinforcing bar, and the reuse bolt is perforated fixedly resistance to plucking sleeve and threaded steel sleeve. Because the contact area of the ring piece is large, the pulling resistance can be effectively increased, the bolt connection is convenient, and the welding deformation is reduced.
Claims (4)
