Abstract
The utility model discloses a connecting sleeve for steel bars of assembly type building members with reinforced concrete members. The connecting sleeve comprises a connecting sleeve and connecting steel bars connected at the two ends of the connecting sleeve, wherein the section at one end of the connecting sleeve is provided with internal threads matched with threads of one connecting steel bar, and the connecting position between the other end of the connecting sleeve and the other connecting steel bar is provided with a connecting device for compensating the length of steel bars. The connecting sleeve disclosed by the utility model has the advantages that the axial compression resistance is greatly improved, the installation accuracy of the connecting steel bars is improved, the two-way steel-bar length compensation is realized, the installation efficiency is improved, and the connecting strength is effectively improved.
Description
Technical field
The utility model 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 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 and draw the reducing link of 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 earlier application patent No. 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 utility model, for above-mentioned the deficiencies in the prior art, provides 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.
It is adjustable that technical purpose of the present utility model is to realize the interior reinforcing bar length of branch sleeve, its key problem in technology is to have increased again by an inner sleeve on the basis of earlier application, internal thread by inner sleeve coordinates and spins with the external screw thread of connecting reinforcement end, 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.
The beneficial effects of the utility model: the utility model, by setting up inner sleeve, has improved the installation accuracy of connecting reinforcement greatly, and has realized two-way concrete slab length compensation, have improved the efficiency of installing, have effectively improved bonding strength.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
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.
