Abstract
The utility model relates to a mechanical reinforcing steel bar connecting process in building operation, in particular to a large-diameter reinforcing steel bar connecting sleeve, which comprises a connecting sleeve, a clamping piece and a fastening sleeve. The large-diameter reinforcing steel bar connecting sleeve is characterized in that the clamping piece is positioned on the inner side of the connecting sleeve, the fastening sleeve is positioned on the outer side of the connecting sleeve, and the clamping piece and the connecting sleeve are wrapped inside the fastening sleeve. The large-diameter reinforcing steel bar connecting sleeve is capable of coaxially and stably connecting two large-diameter reinforcing steel bars (more that phi 16), and effectively bearing and transferring axial tensile force or pressure of the two reinforcing steel bars. Compared with a currently adopted mechanical reinforcing steel bar connecting process, the large-diameter reinforcing steel bar connecting sleeve is capable of effectively decreasing equipment investment, saving construction site area and saving labor, has stable product quality, simple, convenient and rapid working produces as specialization and socialized labor division of quality production are realized, and also can accelerate construction progress.
Description
Technical field:
The reinforcing steel bar machinery that the utility model relates in the building operations connects technology, is a kind of large diameter steel bar connecting sleeve.
Technical background:
At present, reinforcing steel bar machinery connects (thick diameter) technology in China's building operations, there is the reinforced bar sleeve extruding to connect, the taper thread of reinforcing bar sleeve connects, the steel bar thick straight screw sleeve connects, several classes such as reinforcing bars with rolling straight screw sleeve connection, be welded to connect, reinforcing steel bar machinery connects has not only saved steel in a large number, and saved electric energy, auxilliary material such as scolder, but, above-mentioned these a few class mechanical connection technologies and are had common shortcoming, that is: need special reinforcing bar process equipment, and need take limited job site land used, needing to be equipped with certain operating personnel processes, and, also need to be equipped with special quality inspection personnel and check, simultaneously owing to the crudy instability, the processing progress of reinforcing bar directly has influence on next procedure, even influence whole engineering construction progress, not only waste resource, and the quality and the progress of construction all can not get good assurance.
Summary of the invention:
The utility model is the deficiency that exists in the above-mentioned technology, and a kind of large diameter steel bar connecting sleeve is provided.
Large diameter steel bar connecting sleeve described in the utility model is made up of branch sleeve, intermediate plate and fastening sleeve, and it is characterized in that: intermediate plate is positioned at the inboard of branch sleeve, and fastening sleeve is positioned at the outside of branch sleeve, and intermediate plate and branch sleeve are wrapped in its inside.
Branch sleeve is made by No. 45 steel, modified heat treatment, and hardness is HRC32～35, and barrel has the protruding rib of symmetry outward, and all there is external screw thread tube outside, two ends, and two conical sockets are arranged on every port inner wall; Intermediate plate be the cone-shaped clip bevel angle between 5.5 °～7.5 °, the intermediate plate inwall has oblique serration, tooth pitch 2mm, tooth depth is not more than 1.5mm, cone-shaped clip is made by alloy steel 20CrMnTi, the soft tooth way of soft heart, it is HRC60～62 that surface heat is handled back tooth hardness; In the fastening sleeve wall internal thread is arranged, barrel has the protruding rib of symmetry outward, and fastening sleeve is made by No. 45 steel, modified heat treatment, and hardness is HRC32～35.
Large diameter steel bar connecting sleeve described in the utility model can bear and transmit the axial tension or the pressure of two reinforcing bars effectively with the coaxial connection firmly of two diameter steel bars (Ф is more than 16).
Operating principle of the present utility model is, the coaxial connection of diameter steel bar (Ф is more than 16) time, utilize the progradation of fastening sleeve, make cone-shaped clip in the process that is pushed into, serration on the intermediate plate tightly is pressed in the reinforcing bar, and reinforcing bar pressed in the middle of the connecting cylinder, the link of two reinforcing bars holds out against at the midline position of branch sleeve just, can bear and transmit the axial tension or the pressure of two reinforcing bars effectively.
The reinforcing steel bar machinery that adopts connects technology at present, the utility model minimizing equipment effectively drops into, saves the job site land used, saves the labour, owing to realized specialization, the socialization division of labor of production, constant product quality, operation is easy, quick, can also accelerating construction progress.

The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further specified.
By Fig. 1-10 as can be known, the coaxial connection of diameter steel bar 5 (Ф is more than 16) time, two terminations with connected two reinforcing bars 5 penetrate respectively in the fastening sleeve 4 earlier, be inserted into again in the branch sleeve 1, the termination of reinforcing bar 5 is positioned at apart from the about 10mm of the center line of branch sleeve 1 position, then cone-shaped clip 2 is inserted conical socket 3, then fastening sleeve 4 just is screwed on the branch sleeve 1, reinforcing bar can not slided, at last, fastening sleeve 4 is screwed to the stubborn moment values at end of regulation with special torque spanner, in the process that fastening sleeve 4 is tightened, cone-shaped clip 2 is constantly advanced along conical socket 3, and the serration on the intermediate plate constantly tightly is pressed in the reinforcing bar 5, and reinforcing bar 5 is pressed to the centre of branch sleeve 1, because it is stubborn that moment is carried out end in accordance with regulations, so, guaranteed that the link of two reinforcing bars holds out against at the midline position of branch sleeve 1 just, can bear and transmit the axial tension or the pressure of two reinforcing bars effectively.
