Description
Technical field
The utility model relates to the steel bar connecting structure in prefabricated concrete structure, specifically a kind of fabricated construction straight screw sleeve connection joint.
Background technology
Rebar connecting technology is one of key technology of prefabricated assembled concrete structure, and connecting reliably is the key ensureing structural integrity and shock resistance.At present, in prefabricated concrete structure, bar connecting mainly adopts sleeve connection, the connection of slurry anchor and mechanical connection 3 kinds of modes.Sleeve connection to reinforcing bar and prefabricated sleeve portion accuracy requirement very high, a kind of reinforced bar sleeve of internal diameter generally can only be applied to a kind of reinforcing bar of diameter, and sleeve is generally all long, and sleeve all needs special prefabricated, and therefore cost is higher; Require very high to connecting reinforcement during slurry anchor connects, require adopts Ribbed Bar more, and generally do not adopt plain bar, because the anchoring effect of reinforcing bar has a great impact bonding strength, therefore, this connected mode range of application is narrower; Be mechanically connected and require higher to jointing, need to divide multiple grade according to joint ductility, to adapt to multiple reinforced steel bar strength, meet bonding strength requirement, excessive cost need be dropped into.Therefore, the above connected mode is under guarantee connects reliable prerequisite, and most high cost, range of application is narrow, and difficulty of construction is larger.
Utility model content
The utility model is intended to solve bar connecting Problems existing in the structures such as existing assembling frame, shear wall, and provide a kind of easy construction, bonding strength high, under guarantee anatomical connectivity secured premise, greatly reduce difficulty of construction, save the fabricated construction straight screw sleeve connection joint of cost.
The technical scheme that the utility model solves the employing of described problem is:
A kind of fabricated construction straight screw sleeve connection joint, comprise steel bushing, upper power transmission reinforcing bar, lower power transmission reinforcing bar, the inwall of described steel bushing middle and upper part is welded with gilled rings in spaced apart reinforcing bar, steel bushing lower inner wall is welded with the power transmission steel loop of middle its central band internal thread hole; Described lower power transmission reinforcing bar is tightened fixing by its termination external screw thread and described power transmission steel loop; Described upper power transmission reinforcing bar to insert in described steel bushing and is welded with anchor plate in end head, and steel bushing and upper power transmission reinforcing bar and anchor plate thereof are combined as a whole by the high-strength grout be poured in steel sleeve; The axis of upper power transmission reinforcing bar and lower power transmission reinforcing bar on the same line.
Adopt the utility model of technique scheme, compared with prior art, be characterized in:
By anchor plate and upper power transmission bar connecting, and combine together with the grouting material injected in steel bushing, improve the globality of connecting elements; Lower power transmission reinforcing bar threaded end is threaded with power transmission steel loop, can realize self-locking easily, and can keep higher precision.Be applied to precast concrete, there is the advantage connecting reliable, cheap, easy construction, reasonable stress, can workmanship be improved, accelerate speed of application, raise labour productivity, reduce construction cost.
As preferably, the utility model further technical scheme is:
Described steel bushing is common seamless steel pipe or ERW.
In described reinforcing bar, gilled rings is diameter 6-10mm plain bar ring.
Described grouting material is more than C70 grouting material.
Described upper power transmission reinforcing bar and lower power transmission reinforcing bar are diameter 6mm and above all kinds of common plain bar or Ribbed Bar.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
In figure: steel bushing 1, power transmission steel loop 2, lower power transmission reinforcing bar 3, upper power transmission reinforcing bar 4, anchor plate 5, gilled rings 6 in reinforcing bar, high-strength grout 7.
Detailed description of the invention
The embodiment provided below in conjunction with accompanying drawing is further elaborated the utility model, but embodiment does not form any restriction to the utility model.
See Fig. 1, the steel bushing 1 of fabricated construction straight screw sleeve connection joint is common seamless steel pipe or ERW, and its diameter and length require choose reasonable according to fabricated construction design and structure; The top of steel bushing 1 and middle part inner wall position weld gilled rings 6 in a reinforcing bar respectively, and in reinforcing bar, gilled rings 6 is the plain bar ring of diameter 6-10mm; Steel bushing 1 bottom inwall is welded with power transmission steel loop 2, and power transmission steel loop 2 is processed into by certain thickness steel plate, and the external diameter of power transmission steel loop 2 is the internal diameter of steel bushing 1, and the bottom center of power transmission steel loop 2 is processed with internal thread hole; Upper power transmission reinforcing bar 4 and lower power transmission reinforcing bar 3 are the normal tape rib reinforcement of diameter 16mm, and lower power transmission reinforcing bar 3 end machining has the external screw thread mated with the internal thread hole on power transmission steel loop 2, and lower power transmission reinforcing bar 3 is tightened fixing by its male threaded stub and power transmission steel loop 2; Upper power transmission reinforcing bar 4 inserts in steel bushing 1, and upper power transmission reinforcing bar 4 end head is welded with anchor plate 5, pours into high-strength grout 7 in steel bushing 1, and steel bushing 1 and upper power transmission reinforcing bar 4, anchor plate 5 are combined as a whole by high-strength grout 7; The axis of upper power transmission reinforcing bar 4 and lower power transmission reinforcing bar 5 on the same line.
This straight screw sleeve connection joint that embodiment provides, overcomes conventional grout sleeve connection node and adopts longer vertical reinforcement, and bar diameter comparatively thick (>=16mm), often cause the shortcoming that construction is complicated, cost is high.
The foregoing is only the better feasible embodiment of the utility model, not thereby interest field of the present utility model is limited to, the equivalent structure change that all utilization the utility model manuals and accompanying drawing content are done, is all contained within interest field of the present utility model.
