Abstract
The utility model relates to the field of buildings, in particular to a steel bar connector, and aims to overcome the defects in the prior art. Through the arrangement of threads on the outer wall of a hollow shaft, a friction force between the hollow shaft and a sleeve can be greatly increased, thus preventing the sleeve from falling off and improving the stability and the safety. The purpose of the utility model is achieved through the technical scheme as follows: the steel bar connector comprises the hollow shaft and the sleeve, wherein internal threads are formed in the inner wall of the hollow shaft; openings are axially formed in one end, where the sleeve is arranged in a matching manner, of the hollow shaft; a chamfer is arranged at an inner hole at one end of, near to the hollow shaft, of the sleeve; external threads are formed in the outer wall, close to the openings, of the hollow shaft; 2-10 openings are formed, and preferably, 8 openings are formed. The steel bar connector has the advantages as follows: the steel bar connector is wide in application range, is free of restriction of ingredients and types of steel bars, can connect the steel bars with different diameters in any direction and at any position, and can connect the steel bars at an non-rotatable position.
Description
Technical field
The utility model relates to building field, relates in particular to a kind of rebar connector.
Background technology
At present, in building trade, traditional reinforcing bar connected mode has the connected modes such as overlap joint, welding, no matter from quality of connection, efficiency or operability, all can not meet the demand of building trade.The connected mode of overlap joint can not be for the connection of large gauge ribbed bar.And be welded with a lot of weak points: the situations such as unstable in steel material, solderability is poor, tight or the poor situation of welder's level of duration, the situation that power supply is unstable, capacitance is inadequate, the cold situation that waits climatic effect and the high place of fire protection requirement to construct of wind and rain.
Utility model content
The utility model, for prior art above shortcomings, provides a kind of rebar connector.This rebar connector is not subject to the impact of the factors such as the chemical composition, human factor, weather, electric power of reinforcing bar, and pollution-free, meets environmental requirement, flames of anger operation construction safety is reliable.In addition, applied widely, be applicable to various orientation and connection same, reducing reinforcing bar, and intensity is high, steady quality is reliable, simple to operate, and speed of application is fast.The screw thread setting of hollow shaft outer wall can be improved the frictional force of hollow shaft, sleeve greatly, prevents that sleeve from coming off, and has improved stability and safety.
The purpose of this utility model is to be achieved through the following technical solutions:
, comprising hollow shaft, sleeve, described inner wall of hollow shaft is provided with internal thread, and described hollow shaft one end is axially arranged with opening and is combined with sleeve, and described sleeve is provided with chamfering near hollow shaft one end endoporus.
Described hollow shaft outer wall is provided with external screw thread near one end of opening.
Described opening is provided with 2-10.
Described opening is provided with 8.
The utility model beneficial effect: (1) applied range, be not subject to the restriction of reinforcing bar composition and kind, can be connected with the same reducing of position in any direction reinforcing bar, can be to not connecting by rotation place reinforcing bar.(2) can be prefabricated in advance, factory operation, does not take the duration, all-weather construction.(3) easy to operate, quick, speed of application is fast, greatly the reduction of erection time.(4) can comprehensively connect, quality of connection is reliable and stable.(5) save material, energy conservation, pollution-free, construction safety is reliable.
Accompanying drawing explanation
Fig. 1 is rebar connector structural representation described in the utility model.
Fig. 2 is structural representation after rebar connector described in the utility model connects.
In figure:
1-internal thread; 2-external screw thread; 3-hollow shaft; 4-sleeve; 5-opening; 6-chamfering; 7-is connected reinforcing bar.
The specific embodiment
According to drawings and embodiments the utility model is described in further detail below:
As Fig. 1, shown in Fig. 2, a kind of rebar connector, comprise hollow shaft 3, sleeve 4, described hollow shaft 3 inwalls are provided with internal thread 1, the two ends that can make connecting reinforcement being fixed on connector tightly, described hollow shaft 3 one end are axially arranged with 2-10 opening 5 and are combined with sleeve 4, preferred plan is 8 openings, the setting of opening 5 can make to be connected reinforcing bar 7 and enter very easily, described sleeve 4 is provided with chamfering 6 near hollow shaft 3 one end endoporus, its role is to make sleeve 4 under the effect of pressure, to be enclosed within more smoothly in hollow shaft 3, described hollow shaft 3 outer walls are provided with external screw thread 2 near one end of opening.The external screw thread 2 of hollow shaft 3 outer walls arranges the frictional force that can greatly improve hollow shaft 3, sleeve 4, prevents that sleeve 4 from coming off, and improved stability and safety.
While wanting connecting reinforcement, elder generation is reinforcing bar one end mantle fiber and be screwed into hollow shaft away from opening 5 one end, being connected reinforcing bar 7, putting the sleeve 4 of rebar connector and inject hollow shaft opening 5 one end of rebar connector by being connected reinforcing bar 7 one end again, and sleeve is had in chamfering 6 one end and hollow shaft opening one end in contact.By equipment such as pipe wrench, push, beat sleeve 4, make the squeezed sleeve 4 of compressing in hollow shaft opening 5 one end, because inner wall of hollow shaft is provided with internal thread 1, can tightly clamp and be connected reinforcing bar, hollow shaft outer wall is provided with external screw thread 2 simultaneously, and frictional force increases, and prevents that sleeve 4 from coming off, after the sleeve 4 of rebar connector packs in hollow shaft 3 completely, make sleeve 4 be connected more firm with hollow shaft 3.
Claims (4)
