Abstract
The invention relates to a steel bar connecting sleeve of a steel bar concrete assembled-type building component. The steel bar connecting sleeve comprises a connecting sleeve body and connecting steel bars connected to two ends of the connecting sleeve body, wherein an internal thread in threaded fit with one connecting steel bar is arranged on the section at one end of the connecting sleeve body, and a connecting device for compensating the length of the steel bar is arranged at the connecting part between the other end of the connecting sleeve body and the other connecting steel bar. According to the steel bar connecting sleeve disclosed by the invention, the axial compression resistance of the connecting steel bars and the installation precision of the connecting steel bars are improved; in addition, bidirectional length compensation of the steel bars is realized, the installation efficiency is improved and the connecting strength is effectively improved.
Description
Technical field
The present invention relates to a kind of steel bar connecting sleeve of fabricated constructional member of reinforced concrete member, especially to applicant's further improving of first to file 201320507636.6 again.
Background technology
China Patent Publication No. is CN202324365U, a kind of steel bar connecting sleeve of fabricated constructional member of reinforced concrete member is disclosed, connecting reinforcement has steel pipe sleeve outward relatively, steel pipe sleeve one end section has the internal thread with connecting reinforcement threaded engagement, and the other end has and is inserting with another connecting reinforcement and rotates and to draw the reducing being connected.Steel bar concrete assembled architecture member reinforcing steel bar connects does not need welding, not only realized butting member reinforcing bar and connected fast, and quality of connection is secure, and bonding strength meets building completely reinforcing bar is connected to code requirement.The complete mechanical sleeve of two ends connects, not only become strong node, and short of length sleeve needs 90-120mm, only have that sleeve chemistry connects 1/3 even still less, assembly connection cost is low, and there is structural strength after connecting, be conducive to further improve assembling speed of application, realizing erecting yard member reinforcing steel bar does not need to be welded to connect substantially, start steel bar concrete assembled architecture reinforced concrete member reinforcing bar and connected the beginning, but still there is technological deficiency in its technical scheme, first it is inserting and rotates the reducing link draw connection, although can finely utilize reducing to improve the axial tensile strength of reinforcing bar, but when reinforcing bar is carried out to axial compression, owing to existing certain gap in branch sleeve between the connecting reinforcement of two ends when there is axial compression, reinforcing bar can carry out axial displacement, thereby cause that the concrete of cast is because displacement is broken, greatly reduce bonding strength and safety factor, have much room for improvement, moreover in practice of construction operation, the connecting reinforcement of use different in size, always there will be the long or too short phenomenon of reinforcing bar, cannot effectively regulate, and has affected efficiency of assembling, haves much room for improvement.
The applicant's the formerly number of applying for a patent is 201320507636.6, a kind of Gang Jin Quan member assembled architecture member reinforcing steel bar branch sleeve, disclosed technical scheme has solved above-mentioned due to the long or too short problem that cannot effectively regulate of reinforcing bar, its technical scheme is carried out adjustable diameter and screw adjusting by inner sleeve and connecting reinforcement are set in reducing, but can only carry out unidirectional adjusting to its one end, cannot carry out bidirectional modulation, affect the efficiency of assembling, be further improved.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, a kind of steel bar connecting sleeve of fabricated constructional member of reinforced concrete member of effectively realizing reinforcing bar length compensation, improving installation effectiveness is provided.
It is adjustable that technical purpose of the present invention is to realize the interior reinforcing bar length of branch sleeve, its key problem in technology is to have increased again an inner sleeve on the basis of first to file, by the internal thread of inner sleeve and the external screw thread of connecting reinforcement end, coordinate and spin, thereby its length of threaded adjusting, its concrete technical scheme is: Gang Jin Quan member assembled architecture member reinforcing steel bar branch sleeve, comprise branch sleeve, be connected in the connecting reinforcement at branch sleeve two ends, branch sleeve one end is set to the isometrical reducing that diameter is greater than a connecting reinforcement diameter, in branch sleeve, be provided with the inner sleeve spinning with a connecting reinforcement end external screw thread, described inner sleeve external diameter is greater than isometrical reentrant diameter but is less than branch sleeve internal diameter, it is characterized in that described branch sleeve other end section inwall is provided with internal thread, spin with the barrel external screw thread of another inner sleeve of setting up, described another inner sleeve inwall is provided with internal thread, coordinate and spin with the external screw thread of another connecting reinforcement end setting.
As preferably, described two connecting reinforcement outer end diameter are greater than connecting reinforcement diameter.
As preferably, described branch sleeve is hexagon or octagon.
Beneficial effect of the present invention: the present invention, by setting up inner sleeve, has improved the installation accuracy of connecting reinforcement greatly, and realize and to have reinforcing bar length compensation, has improved the efficiency of installing, has effectively improved bonding strength.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Gang Jin Quan member assembled architecture member reinforcing steel bar branch sleeve, comprise branch sleeve 001, be connected in the connecting reinforcement (002 at branch sleeve 001 two ends, 003), branch sleeve 001 1 ends are set to the isometrical reducing 011 that diameter is greater than a connecting reinforcement diameter, in branch sleeve 001, be provided with the inner sleeve 004 spinning with a connecting reinforcement 002 end external screw thread, described inner sleeve 004 external diameter is greater than isometrical reducing 011 diameter but is less than branch sleeve 001 internal diameter, described branch sleeve 001 other end section 012 inwall is provided with internal thread, spin with the barrel external screw thread of another inner sleeve 005 of setting up, described another inner sleeve 005 inwall is provided with internal thread, coordinate and spin with the external screw thread of another connecting reinforcement 003 end setting.Described two connecting reinforcements (002,003) outer end diameter is greater than connecting reinforcement (002,003) diameter.Described branch sleeve 001 is hexagon or octagon.
