Abstract
The utility model provides a beam steel connecting device of a steel reinforced concrete combination structure. The problems to be solved include that the butt joint of two segments of beam steels is currently achieved by means of welding or binding overlapping joints, wherein the butt welding involves more manpower and devices, causes lower construction speed, and particularly hardly guarantees the welding quality of steels with a large diameter. Alternatively, the overlapping joint binding wastes steels of overlapping portions is not suitable for binding overlapping of steels with a large diameter, and can not guarantee the construction quality. The points of the utility model include that the overall inner wall of a connecting pipe is provided with continuous internal threads, the surfaces of beam steel joints on the left side and the right sides are respectively equipped with one segment of external threads capable of being engaged with the internal threads of the connecting pipe, and the length of external threads on one side of the beam steel joints is longer than or equal to that of the connecting pipe. The utility model has the advantages of convenient operation, fast construction speed, high connecting intensity, guaranteeing construction quality, and saving materials.
Description
Technical field
The utility model relates to a kind of linkage that two sections beam steels are coupled together, and specifically is, in reinforced concrete composite structure, need weld two sections beam steels between two steel columns, with these two sections linkages that beam steel couples together.
Background technology
In reinforced concrete composite structure, need be between two steel columns the welded grider reinforcing bar, because of distance between two steel columns is very big, so beam steel is generally more than two sections.After the one end welding of steel column and wherein one section beam steel, again with two sections beam steel butt joint.Because the steel column fixed-site at beam two ends, and beam steel is a rigidity, two beam steel butt joints can't be adopted conventional mechanical connecting joint (in the conventional mechanical connecting joint two sections internal threads being arranged), so the butt joint of two sections beam steels can only be adopted welding or colligation lap joint.Adopt jam weld will drop into more manpower and equipment, speed of application is slow, and particularly the diameter steel bar welding quality is difficult to guarantee.If adopt the colligation lap joint then to waste the reinforcing bar of lap, and the unsuitable colligation overlap joint of diameter steel bar, construction quality can't guarantee.
Summary of the invention
For overcoming the deficiency of prior art, the purpose of this utility model is to provide a kind of reinforced concrete composite structure beam steel linkage.
The purpose of this utility model is achieved in that it has tube connector and left and right sides beam steel joint, it is characterized in that: on the whole tube connector inwall continuous internal thread is arranged, the surface of left and right sides beam steel joint respectively have one section can with the external screw thread of tube connector screw-internal thread fit, wherein the externally threaded length of a side (such as the left side) beam steel joint is more than or equal to the length of tube connector.Using method is, tube connector is screwed on the joint of left side beam reinforcing bar, up to all being screwed into, again the joint of right side beam reinforcing bar is aimed at the left side beam bar splice, tube connector is reversed, tube connector progressively withdraws from the left side beam reinforcing bar and screws in the right side beam reinforcing bar, and end in the centre position that is in tube connector until two beam steel seams.
Compared with prior art, the beneficial effects of the utility model are: easy to operate, speed of application is fast, and the bonding strength height guarantees construction quality, saves material.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is a schematic diagram of the present utility model.
Fig. 2 is the schematic diagram before tube connector and the assembling of left and right sides beam steel joint.
Fig. 3 is the tube connector schematic diagram that is screwed into of beam steel joint to the left.
Schematic diagram when Fig. 4 is the counter-rotating tube connector.
Fig. 5 is the schematic diagram that tube connector and the assembling of left and right sides beam steel joint finish.
The specific embodiment
Referring to Fig. 1 and 2, it has tube connector 2 and left and right sides beam steel joint 1,3, on the whole tube connector inwall continuous internal thread is arranged, the surface of left and right sides beam steel joint respectively have one section can with the external screw thread of tube connector screw-internal thread fit, wherein the externally threaded length of left side beam bar splice is more than or equal to the length of tube connector.Using method is, referring to Fig. 3, tube connector is screwed on the joint of left side beam reinforcing bar, up to all being screwed into, again the joint of right side beam reinforcing bar is aimed at the left side beam bar splice, with tube connector counter-rotating (referring to Fig. 4), tube connector progressively withdraws from the left side beam reinforcing bar and screws in the right side beam reinforcing bar, is in the tube connector position intermediate until two beam steel seams and ends (referring to Fig. 5).
For improving bonding strength, the beam steel external thread section should be cone of nulls degree.
