Description

Gang Jin Quan member assembled architecture member reinforcing steel bar branch sleeve
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 201120419317.0 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, again moreover when carrying out steel reinforcement abutting joints installation exercise, branch sleeve up and down or left and right concentricity always have deviation, slightly putting deviation will make sleeve not dock with silk mouth, although can beat or with the adjustment of steel crowbar with poll pick, easily make under these circumstances that prefabricated concrete is damaged, personnel operate instruments dangerous, operating personnel generation accident, the operating efficiency quality not high, that lack a sense of responsibility that can fall down and do not guarantee in engineering.
Summary of the invention
The utility model is for above-mentioned the deficiencies in the prior art, a kind of axial compression that effectively prevents is provided, improve bonding strength, and can realize the steel bar connecting sleeve of fabricated constructional member of reinforced concrete member of reinforcing bar length compensation, raising reinforcing bar concentricity, raising installation effectiveness.
It is adjustable that first 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 on the basis of existing technology an inner sleeve, 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, described branch sleeve one end section is provided with the internal thread with a connecting reinforcement threaded engagement, it is characterized in that the other end and another connecting reinforcement junction are provided with for compensating the linkage of reinforcing bar length.Described linkage comprises and is arranged at branch sleeve end and diameter is greater than the isometrical reducing of connecting reinforcement diameter and is provided with the inner sleeve that coordinates internal thread with 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, described connecting reinforcement end is stretched in branch sleeve through isometrical reducing, spins with the interior inner sleeve being placed in branch sleeve.
Another technical purpose of the present utility model is to improve the concentricity of connecting reinforcement, make inner sleeve and connecting reinforcement screw thread spin simpler, convenient, its key problem in technology is realizing on the basis of the first technical purpose, at inner sleeve end, be inserted with a contraposition cushion block, the corresponding center, connecting reinforcement end being connected with branch sleeve threaded one end offers contraposition centre bore, first inner sleeve is inserted in branch sleeve, then at inner sleeve end, insert contraposition cushion block, then a connecting reinforcement and branch sleeve internal thread are spun, when the taper of contraposition cushion block slips in contraposition centre bore to potential head because screw thread spins, and when pressure-bearing plate surface compresses with connecting reinforcement end face, centralized positioning completes, make the connecting reinforcement of the branch sleeve other end spin simpler through isometrical reducing and inner sleeve, convenient.Its concrete technical scheme is: described inner sleeve end has additional contraposition cushion block, the taper that socket joint head, the diameter that described contraposition cushion block equals inner sleeve internal diameter by diameter equals the pressure-bearing plate of inner sleeve external diameter and be arranged at contraposition cushion block center forms potential head, described socket joint head inserts in inner sleeve end, the described center, connecting reinforcement end being connected with branch sleeve threaded one end offers contraposition centre bore, and described contraposition center-hole diameter equals the maximum diameter of taper to potential head.
The utility model the 3rd technical purpose realizes and being when realizing the second object, due to inner sleeve, contraposition cushion block and the connecting reinforcement that is threaded with branch sleeve, three compresses mutually, makes not exist between inner sleeve and connecting reinforcement gap, thereby realizes the object of axial compression resistance.
As of the present utility model preferably, describedly female branch sleeve end section be set be set to taper thread.
As preferably, a described connecting reinforcement end is set to the conical head connecting with taper thread.
As preferably, a described connecting reinforcement outer end diameter is greater than connecting reinforcement diameter.
As preferably, described branch sleeve is hexagon or octagon.
The beneficial effects of the utility model: the utility model is by setting up inner sleeve, contraposition cushion block and center registration holes, the installation accuracy that has greatly improved axial compression resistance performance and improved connecting reinforcement, and realize and to have reinforcing bar length compensation, improved the efficiency of installing, effectively improved bonding strength.
