Abstract
The utility model relates to an active sleeve connecting joint for ribbed steel reinforcements, comprising a connecting sleeve and a threaded steel reinforcement end. The utility model is characterized in that the connecting sleeve is formed by two semicylindrical connecting sleeves. The inner surface of the connecting sleeve is provided with a spiral groove which has the same shape with the threaded steel reinforcement, and the outer surface of the connecting sleeve is sheathed with an annular hoop. The utility model has fast construction speed and reliable joint quality. The property of the joint position is superior than the mechanical property of the base material of a steel reinforcement. The utility model uses less steel than other connecting methods, and only a handy manual jig is needed, so the utility model can reduce labor intensity for labors and can decrease engineering cost. The utility model is used in construction for connecting ribbed steel reinforcements whose diameter phi is larger than 18 mm and the diameter is same or different.
Description
The utility model relates to a kind of rebar connector.
In building operations, high-rise and to stride the frame concrete building greatly increasing, bar diameter and Bu Jin density are increasing, and reinforcing bar connects has become one of key of structure design and construction.Existing connecting method for reinforcing bars has colligation, welding, taper thread to connect with sleeve methods such as cold extrusion is connected.First three methods has shortcomings such as the big and workman of waste steel, power consumption need train; Sleeve cold extrusion connection method need be equipped with the high pressure pumping plant, during connection, the workman need hand the pressing tongs operation, pressing tongs weight is more than 40 kilograms, labor strength is big, and often everything goes well with your work carries out because of leakage of oil influences, and the cost height, be difficult for large scale application, press for development new rebar connector and method.
The purpose of this utility model provides a kind of Ribbed Bar kink jointing, and it is convenient, rapid, reliable that reinforcing bar is connected, and only uses simple tool, alleviates labor strength, saves steel.
The technical solution of the utility model is:
This Ribbed Bar kink jointing comprises adapter sleeve and indented bars termination, it is characterized in that: adapter sleeve is two semi-cylindrical shaped adapter sleeves, and inner surface has the helicla flute identical with the screw thread steel shape, and the adapter sleeve outside is with circumferential band.
Above-mentioned two semi-cylindrical shaped adapter sleeves fasten the back less than a full circle tubular.
Connection procedure of the present utility model: two butt joint reinforcing bars are put into two semi-cylindrical shaped adapter sleeves, and match with the inside helicla flute, only with a manual, the cross rib of adapter sleeve groove and indented bars tightly is interlocked, again two hoops are enclosed within on the adapter sleeve, and, make hoop and adapter sleeve and reinforcing bar form an integral body with the manual wedging of pressurizeing.
The utility model has the advantages that: speed of application is fast, and joint quality is reliable, and the performance of joint surpasses the mechanical performance of parent material of reinforcement rebar, saves steel than other method of attachment, only needs the portable manual anchor clamps, reduces labor strength and construction costs, is easy to promote.Be applicable to that diameter phi 18mm is above with footpath or the connection of reducing Ribbed Bar in the building operations.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, Ribbed Bar kink jointing, comprise adapter sleeve 1 and indented bars termination 3, it is characterized in that adapter sleeve 1 is two semi-cylindrical shaped adapter sleeves, inner surface has the helicla flute 4 identical with the screw thread steel shape, the adapter sleeve outside is with 2, two semi-cylindrical shaped adapter sleeves of two circumferential band and fastens the back less than a full circle tubular.Adapter sleeve can use identical steel with reinforcing bar to make with hoop, also can make of other steel that can satisfy requirement of strength.When reducing connects, step can be processed in adapter sleeve inside.
