Abstract
The utility model relates to a wedge-cone type reinforced bar joining apparatus, which is the improvement of the connecting mode of two reinforced bars in a building structure at present. The end heads of the two connected reinforced bars are respectively provided with a multi-petal wedge-cone sleeve which is coincident with the screw threads of the reinforcing bars; the outer sides of the two connected reinforced bars are respectively sheathed with a sleeve barrel which is provided with inner cone holes and inner threads on a tail part; a screw bolt is screwed in the tail parts of two outer sleeve barrels which are provided with inner threads to screw to the multi-petal wedge-cone sleeve on the top two sides. Thereby, the wedge-cone type reinforced bar joining apparatus can improve connecting strength and can simultaneously operate safely, conveniently and reliably. In addition, the utility model can realize serial matching development to cause the selection of the reinforced bar joining apparatus in the building design of China to enter international standardization.
Description
The utility model relates to a kind of reinforcing bar hookup that is used for building structure reinforcing bar and reinforcing bar connection usefulness.It comprises two identical wedge tapered sleeves, and this wedge tapered sleeve is to be divided into many lobes wedge tapered sleeve sheet at circumferencial direction, so that be contained on two reinforcing bar external surfaces.Other has two sleeve and bolts that hold out against the wedge tapered sleeve of tightly pushing down the wedge tapered sleeve.
At present, reinforcing bar bind mode for building does not still have standard so far, only is confined to the job site operation, commonly used have a manual arc welding, and not only operating environment is poor, and labour intensity is big, importantly destroy, cause to be difficult to guarantee bonding strength owing to welding causes reinforcing bar two termination metallographic structures.Gradually adopted the mechanical type hookup to connect in recent years, be to cut tapered thread with special purpose machinery on the reinforcing bar top, connect with the taper thread that connects then, it is not enough to exist tensile strength during this mode is put into practice, and must there be the screw cutting special equipment at the scene, this will make operating personnel feel inconvenience deeply, and labour intensity strengthens and has influence on extensive use.
The utility model purpose is:
A kind of structural integrity is provided, produces serial reinforcing bar hookup, can directly just reinforcing bar can be tied with special tool at the construction field (site), and need not main equipment and naked light equipment by unlike material, different size.Both guaranteed tensile strength, alleviated labor intensity of operating personnel again, energy safety, easy construction.
The utility model implementation is as follows:
This reinforcing bar hookup is by two wedge tapered sleeves that are divided into many lobes, the screw thread of nest plate inner face and the tightly interlock of the external screw thread of reinforcing bar, the outside respectively puts the sleeve of internal taper hole and a bit of internal thread after tightening up, there is one section of internal taper hole will press with wedge tapered sleeve external surface, and then screw in two female sleeve afterbodys that will connect, until holding out against the wedge tapered sleeve with bolt.Bolt and two sleeves are the screw thread self-locking state.
Advantage of the present utility model is:
This hookup can make on the stressed end face that does not concentrate on connection of two reinforcing bar tensile strength, but be distributed on the circumference of each section of reinforcing bar, bear jointly by the groove screw thread of wedge tapered sleeve and the external screw thread screw thread self-locking tightly identical and bolt and outer sleeve of reinforcing bar, stressed segment distance is long, in addition, this hookup can not make steel bar end be subjected to any thump, the metallographic structure of steel bar end material can not change, different reinforcing bar materials is selected different reinforcing bar hookups for use simultaneously, can improve tensile strength, and can be safe, easy, install at the construction field (site) reliably.
Accompanying drawing is the utility model structural representation.
Below in conjunction with accompanying drawing the utility model is done further narration:
The utility model taper sleeve type reinforcing bar hookup is made up of on two terminations that are contained in two reinforcing bars that needs are connected respectively two groups of identical parts 1 of physical dimension and 2.Central with two groups of parts of a bolt 3 connections.
As shown in the figure, the utility model is made of 1, two internal taper hole of wedge tapered sleeve and 2, bolts of the female sleeve of afterbody 3 of two distinguish that match with screw thread steel.The utility model can directly couple together two reinforcing bars.Strengthened reinforcing bar tensile strength, handling safety, easy, improved operating environment.
Claims (1)
1, a kind of wedge bevel-type reinforcing bar hookup, be included in two of connection and respectively adorn many lobes wedge tapered sleeve that matches with screw thread steel on end reinforced, this cover outside respectively puts one and has only internal taper hole and the female sleeve of afterbody, and a bolt is used for screwing in two same size afterbodys and has in the sleeve of internal thread segment, direct rotary is main to the many lobes wedge tapered sleeve that holds out against two limits, make bolt and two sleeves be the screw thread self-locking state
It is characterized in that: the wedge tapered sleeve is many lobes wedge tapered sleeve sheet, the screw thread of nest plate inner face and the external screw thread of reinforcing bar match, one section outside that is pressed on many lobes wedge tapered sleeve that internal taper hole is arranged in the sleeve, in addition female one section so that bolt screws in and holds out against many lobes wedge tapered sleeve of two ends.
