Abstract
The utility model provides a sleeve type connecting piece connecting a beam steel with a section steel column. The problems to be solved include that the first means for connecting the beam steel with the section steel column is reserving connecting holes on the section steel column, and then connecting the section steel column with the beam steel, the means costs time and labor and weakens intensity of the section steel column. Alternatively, the second means is arranging a steel corbel on the section steel column, and then welding the section steel column with the beam steel, the means causes heavy workload and lower construction speed. The points of the utility model include that the connecting piece is a round sleeve, the inner wall of the sleeve is provided with internal threads, a combination surface of the sleeve and the section steel column is equipped with a chamfer angle, the surface of the beam steel is processed into external threads capable of being engaged with the sleeve, and then the combination surface of the sleeve is welded on the section steel column. The utility model has the advantages of greatly improving construction efficiency and guaranteeing structure intensity.
Description
Technical field
The utility model relates to a kind of connector, specifically is the telescopic connector that beam steel and steel column are coupled together.
Background technology
At present in reinforced concrete composite structure, the method for attachment of the steel column in beam steel and the combining structure post there are following two kinds: the one, on steel column, reserve connecting hole, be connected with beam steel.This method requires position, the quantity of preformed hole very accurate, time-consuming taking a lot of work, and the intensity of meeting undue weakening steel column after particularly intensive when beam steel, perforate is too much is if its expense of reinforcement is too high; The 2nd, steel corbel is set, beam steel and steel corbel welding on steel column.This method welding job amount is too big, speed of application slows down greatly, need drop into a large amount of labours and welding equipment during construction, generally should not weld when surpassing Φ 28 diameter steel bars and HRB400 grade reinforcing steel, and beam steel generally adopts HRB400 level bar reinforcement in the present reinforced concrete composite structure, its welding quality is difficult for guaranteeing that difficulty of construction is big and cost is too high.
Summary of the invention
For overcoming the deficiency of prior art, the purpose of this utility model is to provide a kind of telescopic connector that beam steel and steel column are coupled together.
The purpose of this utility model is achieved in that it is a circular sleeve, and the tube inwall has internal thread, on the bonding surface of sleeve and steel column chamfering is arranged.Using method is: the external screw thread that beam steel Surface Machining Cheng Keyu internal thread of sleeve is cooperated also is screwed into, and is about to jacket casing on beam steel, and the bonding surface with sleeve is welded on the steel column again.Chamfering can make bonding area increase, and improves weld strength.
The beneficial effects of the utility model are: improved efficiency of construction greatly, guaranteed the intensity of structure.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is beam steel, telescopic connector and steel column connection status schematic diagram.
Fig. 3 is variable cross-section sleeve and apsacline steel column connection status schematic diagram.
The specific embodiment
Referring to Fig. 1, it is a cylindrical shape 2, and the tube inwall has internal thread 21, and chamfering 22 is arranged on the bonding surface of sleeve and steel column, and chamfer angle is 45 °.Using method is (referring to Fig. 2): the external screw thread that beam steel 1 Surface Machining Cheng Keyu internal thread of sleeve is cooperated also is screwed into, and the bonding surface with sleeve is welded on the steel column 4 again.3 is solder joint.
Referring to Fig. 3, when steel column tilted, the bonding surface of cylinder and steel column was a variable cross-section, and at this moment the angle of inclination of bonding surface is identical with the angle of inclination of steel column.
Claims (2)
1, a kind of telescopic connector is characterized in that: it is a circular sleeve, and the tube inwall has internal thread, on the bonding surface of sleeve and steel column chamfering is arranged.
2, according to the described telescopic connector of claim 1, it is characterized in that: said chamfer angle is 45 °, and the angle of inclination of sleeve bonding surface is identical with the angle of inclination of steel column.
