Abstract
A butt-joint device for thick reinforcing steel bars for building construction comprises a pair of nuts and a pair of clamping plates with semicircular sections, wherein grooves matched with external threads of the reinforcing steel bars are formed in the inner sides of the clamping plates, and external threads matched with the nuts are respectively formed in two ends of the outer sides of the clamping plates. The butt joint device is produced by a professional factory, the quality is reliable, the strength is high, the universality is strong, the operation is simple and convenient, any auxiliary equipment and electric power are not needed in construction, the butt joint can be completed only by a wrench, the technical requirements on operators are reduced, the working efficiency is improved, and the use cost is greatly reduced.
Description
The utility model relates to the coarse-pitch thread reinforcing bar docking adapter in a kind of building operations, especially a kind of nipple of strap clamp plate.
In building bar reinforcement butt joint field, traditional solder technology is replaced by the mechanical attachment technology gradually.At present, mostly adopt sleeve extruding and taper thread connection technique, and also obtained practical function and certain economic benefits preferably.But,, even parent material of reinforcement rebar is carried out field machining and assembling because the use of sleeve squeezed joint and taper thread joint all must be by means of auxiliary equipment and electric power.For example, the sleeve extruding connects must be equipped with specific hydraulic machine and mould thereof etc. at the construction field (site), the taper thread joint also must be established semiworks on construction ground in addition, special-purpose taper thread is installed is cut the pin machine, reinforcing bar pier nose machine and emery wheel blank cutter etc., the configuration of these equipment, brought management to construction party undoubtedly, operation, training, inconveniences such as transportation, not only directly influence construction speed, simultaneously also increased use cost, but also will be subjected to the restriction of conditions such as peopleware and electric power, therefore, the continuous use of mechanical splice has proposed new problem also for the allegro modern of life.
The purpose of this utility model provides a kind of need can be finished the reinforcing bar butt joint with the wrench operation rapid abutting joint device.
The purpose of this utility model is achieved in that it comprises a pair of nut, and a pair cross-section is semicircular clamping plate, and the clamping plate inboard is provided with the groove that matches with reinforcing bar outside screw thread form, and two, the clamping plate outside is respectively arranged with the external screw thread that matches with nut.
During use, earlier a pair of nut is enclosed within the head of two joint coarse-pitch thread reinforcing bars to be docked respectively, and then two clamping plates is fastened on the joint of coarse-pitch thread reinforcing bar to be docked, cooperate with the external screw thread at clamping plate two ends respectively with the nut of spanner at last, screw and two joint coarse-pitch thread reinforcing bar butt joints can be integral both sides.
The utility model compared with prior art has following advantage:
1, product is all carried out specialized plant produced, thereby has guaranteed the quality and the interchangeability of component, production efficiency height.
2, strength of joint height, stable performance is not only because the tension net section of curved splint is long-pending greater than steel area, guaranteed the intensity of the intensity of joint more than or equal to parent material of reinforcement rebar, and, also because parent material of reinforcement rebar need not machine, and can not cause the damage of the mechanical performance of mother metal.
3, connection speed is fast, and use cost is low.It is simple to operate, convenient, do not need execution conditions such as auxiliary equipment and electric power in the construction, as long as can correctly grasp the using method of spanner can tighten in accordance with regulations and be up to state standards, not only reduced technical requirements to operating personnel, and improved operating efficiency, guaranteed construction speed, its connection speed is the fastest in all mechanical splice technology, is adapted to especially bending reinforcing bar, reinforcing cage and the fixedly connection that can't rotate such as reinforcing bar.

Fig. 2 is the clamp region schematic diagram
Fig. 3 is the lateral view of clamping plate
Describe concrete structure of the present utility model in detail below in conjunction with accompanying drawing and embodiment.
Referring to Fig. 1-3, the utility model comprises that pair of inside is the nut 1 of taper, a pair of its cross section is semicircular clamping plate 2, clamping plate 2 inboards are evenly equipped with tilting crescent shaped groove 3, wherein one is left-handed crescent, another piece is then for the dextrorotation crescent, two close up after just with the reinforcing bar that dock outward the shape of crescent moon match, there is the outer cone thread 4 that matches with the inside tapered thread of nut 1 in the outside two ends portion of clamping plate 2 car respectively.In addition, for two the convenient of joint reinforcing bars that satisfy different-diameter dock, the utility model also can be made clamping plate 2 the semicircle clamping plate of the little two-section different-diameter in big other end, and corresponding two nuts that cooperate with it also should be the different nut of small one and large one internal diameter.
Claims (4)
