Abstract
The utility model relates to an air pressure welding clip used for connecting the steel bar which is particularly suitable for using in the building operations. The aim of the air-pressure welding clip for wedge rack-type concrete iron is to improve the centering performance and efficiently guarantee the welding quality. The utility model mainly adopts a wedge block device, a gear wheel device and a rack bar device in the inside of an upper collet and a lower collet. The utility model has the advantages of convenient operation, time saving and labour saving, reliable clamping force, the indestructibility of the steel bar, good centering performance and guaranteed quality of the welding joint, which can do pressure welding to the steel bar with the same diameter or different diameters and can be difficult to deflect and surge.
Description
The utility model is to be specially adapted in the construction, a kind of anchor clamps of gas pressure welding connecting reinforcement.
In the prior art, traditional method is that reinforcing bar to be connect in the construction is taked to overlap colligation or electroslag pressure welding butt joint, and the intensity of its welding, quality etc. are all not good enough.Begin in recent years to adopt steel bar gas to connect, this on-the-spot reinforcing bar for construction connects has opened up a new road, obtains promotion and application.But still there are some significant disadvantages in air pressure employed anchor clamps of when welding: because existing anchor clamps are directly to compress reinforcing bar by four bolts (jackscrew), 4 stressed fixing down, this anchor clamps one are to get loose easily, be shifted, and cause the welding point deflection; The 2nd, tighten and to unclamp bolt effort time-consuming, need tightening card jail one by one, use inconvenience; The 3rd, bolt is worked under hot state, and the intensity of itself is reduced, and the bolt easy deformation, and is stuck in the chuck screw, so whole anchor clamps scrap, influence service life; Be for strengthening clamping force, often on reinforcing bar, eject pit, having reduced intensity of reinforcing bar or the like again.
The purpose of this utility model be to develop a kind of easy to use, hold firmly, good to neutrality, the air pressure welding clamping device that efficient is high.
Voussoir rack-and-pinion gas pressure welding anchor clamps are seen accompanying drawing 1, by clamp body (1), and guide pillar (2), return spring (3), upper grip (4), several most of compositions such as lower chuck (5); Upper grip is connected with guide pillar, and guide pillar can move along center line in clamp body; Lower chuck is fixed on the clamp body; Upper and lower chuck is corresponding consistent the installation on clamp body; Main is that voussoir (6) and gear shaft (7) also are housed on upper and lower chuck, during the turning gear wheel shaft, can drive voussoir and move along the clamp body axis direction in chuck.Voussoir is seen accompanying drawing 7,8,9,10, and it is a right angle trapezoid block shape member, and central plane has V-shaped groove at the right angle, on the V-shaped groove face sawtooth is arranged; On the another side of block member, tooth bar is arranged.Gear shaft (7) is seen accompanying drawing 6, and it is an axle shape gear that can be meshed with the tooth bar on the voussoir, and there is the spindle nose that Gong turns its end.For guaranteeing the voussoir V-arrangement in the face of title and parallel with the clamp body center line, upper and lower chuck is installed the voussoir place and is processed into the trapezoidal slideway that matches with voussoir, and the corresponding positions vertical with the slideway symmetrical center line is equipped with the through hole of mounting teeth wheel shaft, sees accompanying drawing 4,5,6.During use, lower chuck is clamped on the reinforcing bar that solidifies in concrete, upper grip is clamped in to be waited to connect on the reinforcing bar, and the V-shaped groove on the voussoir can make two reinforcing bar self-centerings, aligns, and the sawtooth of V-shaped groove face helps the firm reinforcing bar of card.Turning gear wheel shaft (7) moves by the rack drives voussoir on the voussoir, just can realize the clamping of reinforcing bar or gets loose.Whole anchor clamps are used devices such as pressurizer, oil pump again, and pressurization in the gas welding heating promotes guide pillar compression spring and drive reinforcing bar to be connect to be synchronized with the movement, and two reinforcing bars are crimped on together the most at last.
The superiority of these anchor clamps is: 1. clamping force is reliable, belongs to the multiple spot pressurization and to the reinforcing bar not damaged; 2. simple to operate, time saving and energy saving, clamp or get loose rapidly, need only use spanner, move first angle and get final product; 3. do not have the stuck problem of bolt or parts, fault is few, long service life and be easy to repair; 4. but pressure welding is with the reinforcing bar of diameter or different-diameter, and is good to neutrality, is difficult for the deflection slippage, guarantees welding head quality.

As embodiment, voussoir (6) is seen accompanying drawing 7,8,9,10,14 ° of the angles of wedge, 135 ° of V-arrangement face angles., it is suitable for pressure welding φ 18～φ 38 reinforcing bars; Gear, tooth bar adopt the positive profile of tooth of standard of modulus 2.5, the gear number of teeth 10; The spindle nose of gear shaft (7) is a square, locatees with screw (8) on chuck; 14 ° at the slideway oblique angle that accompanying drawing 4 cooperates with voussoir is seen in chuck (4), (5), and slide groove communicates with the gear shaft installing hole, guarantees gear shaft and voussoir tooth bar energy normal engaged.Accompanying drawing 1,2,5 is seen in voussoir (6), the installation site of gear shaft (7) on upper and lower chuck (4), (5).
Claims (3)
1, a kind ofly is specially adapted to construction, the gas pressure welding anchor clamps of connecting reinforcement, it is by clamp body, several most of compositions such as guide pillar, spring, upper grip, lower chuck, upper grip is connected with guide pillar, guide pillar can move along center line in clamp body, lower chuck is fixed on the clamp body, upper and lower chuck is corresponding consistent the installation on clamp body, it is characterized in that also being equipped with on the upper and lower chuck voussoir (6) and gear shaft (7), during the turning gear wheel shaft, can drive voussoir and in chuck, move along the clamp body axis direction.
