Abstract
A finishing deformed steel bar connector relates to a reinforcing steel bar connector used for construction. The finishing deformed steel bar connector consists of a connecting sleeve 1 with internal threads at each end and a locking cap 2 outside each end. When the utility model is used for connecting finishing deformed steel bars, screw a finishing deformed steel bar 3 into internal screwed holes at each end of the connecting sleeves, featuring easy and firm connection. The locking caps outside each end of the connecting sleeves can be used for assisting the connection between the reinforced steel bar and the connecting sleeve, thereby preventing disturbance. The internal threads here can be of equal or reducing diameter, and a grout hole, a slurry injection hole, or a discharge hole is applicable to facilitate the injection of cement or mortar or epoxide resin, thereby controlling the slide of joints. The locking cap 2 is of a standard cap or an eccentric cap, but better tightening effect can be achieved by applying the eccentric cap. If the utility model is used for connecting finishing deformed steel bars, the strength, deformation, ductility and toughness of two steel bars will be similar to those of finishing deformed steel bars.
Description
Technical field
The utility model relates to a kind of reinforcing bar connector for building.
Background technology
Existing reinforcing bar, there is cross rib on the two sides of reinforcing bar, the reinforcing bar of this form, reinforcing bar is connected with overlapping mode with reinforcing bar, or with the sleeve squeezed joint two reinforcing bars is linked together; Or the link of two reinforcing bars is processed into taper, then connect with the taper thread joint; Or the link of two reinforcing bars processed straight thread with cold extrusion or hot extrusion mode, then connect with straight thread connector.The applicant has applied for finish rolling deformed bar, and the reinforcing bar cross rib is a shape of threads.This reinforcing bar connects between the reinforcing bar, and reinforcing bar and steel work are easy to connect, firm.
Summary of the invention
The purpose of this utility model aims to provide a kind of rational in infrastructure, and is easy to connect between the reinforcing bar, firm, and the intensity of junction, distortion, ductility and toughness are as the finish rolling deformed bar connector of finish rolling deformed bar.
The implementation of the utility model purpose is, the finish rolling deformed bar connector has the adapter sleeve 1 of internal thread and the block nut 2 outside the two ends is formed by two ends, and adapter sleeve 1 has grout hole 4.
When the utility model is used for the finish rolling deformed bar connection, only need get final product in the internal thread hole with finish rolling deformed bar 3 screw-in adapter sleeve two ends, easy to connect, firm.Block nut outside adapter sleeve 1 two ends, but being connected of auxiliary reinforcement and adapter sleeve, and avoid the generation of disturbing phenomenon.The internal thread at adapter sleeve two ends can be with footpath or reducing, grout hole is arranged or fill slurry injection hole, tap, and convenient filling concrete mortar or the epoxy resin of injecting is with the slip at control connection position.
Connect finish rolling deformed bar with the utility model, can make intensity, distortion, ductility and toughness and finish rolling deformed bar after two sections reinforcing bar straight lines connect close.

The specific embodiment
With reference to Fig. 1, the utility model has the adapter sleeve 1 of internal thread by two ends and the block nut 2 outside the two ends is formed.When the utility model is used for the finish rolling deformed bar connection, only need get final product in the internal thread hole with finish rolling deformed bar 3 screw-in adapter sleeve two ends, easy to connect, firm.Block nut outside adapter sleeve 1 two ends, but being connected of auxiliary reinforcement and adapter sleeve, and avoid the generation of disturbing phenomenon.
With reference to Fig. 2, the internal thread at adapter sleeve 1 two ends is with the footpath, is used for the connection of the identical finish rolling deformed bar of external diameter.With reference to Fig. 3, the internal thread at adapter sleeve two ends is a reducing, is used for the connection of external diameter finish rolling deformed bar inequality.
With reference to Fig. 1,4, adapter sleeve 1 has grout hole 4, and finish rolling deformed bar can conveniently pour into filling concrete mortar or epoxy resin from grout hole 4, with the slip at control connection position after screwing in internal thread hole and location.The amount of irritating many is discharged from adapter sleeve 1 both sides.Adapter sleeve 1 has anchor ingot plate 5, and anchor ingot plate has increased the firm attachment power of adapter sleeve itself.
With reference to Fig. 5, adapter sleeve 1 has only an end that internal thread is arranged, and is used to connect finish rolling deformed bar, does not have an end of internal thread to link to each other with general reinforcing bar, and it is mainly used in pre-casting method.Adapter sleeve 1 has the slurry of filling injection hole 7, tap 6, finish rolling deformed bar screws in adapter sleeve, after general reinforcing bar is put adapter sleeve and location into, can be from injection hole 7 convenient filling concrete mortar or the epoxy resin of injecting, to control the slip between general reinforcing bar and adapter sleeve connecting portion.Annotating many amounts discharges from tap 6.
With reference to Fig. 6, block nut 2 is a standard cap.
With reference to Fig. 7, block nut 2 is an eccentric nut.With reference to Fig. 8, when eccentric block nut is used to connect, because the center line of its misalignment finish rolling deformed bar can produce two inside crowded power p
1, p
2With the torsion p that produces because of off-centre
3, fastening force=p
1+ p
2+ p
3, fastening better effects if.This eccentric block nut can be applicable to engineerings such as precasting bridge side version, system's masterplate support and foundation bolt.
