Embodiment 1

[0016] Reinforcement taper thread connection technology, its composition includes: preparatory work, taper thread processing manufacture, reinforcement cage manufacture, reinforcement cage installation, described reinforcement cage manufacture is to hang the bottom segment reinforcement cage into the hole, and temporarily fix the reinforcement cage top In the process of putting the reinforcement cage into the hole on the casing, the auxiliary support ribs should be cut off, which can be reused again. Lift the second reinforcement cage and connect it with the bottom reinforcement cage, and adjust the boom of the crane , and rotate the reinforcement cage at the same time to align the main reinforcement corresponding to the two reinforcement cages, and tighten the sleeve with a torque wrench.

[0017] In the tapered thread connection technology of steel bars, the preparatory work is to straighten the steel bars and cut off the irregular ends. The tapered thread processing is to lo...

Abstract

The invention relates to a reinforcing steel taper threaded connection technique. In the construction of bridge engineering, the problems of the connection technique of reinforcing steels and the connection quality always trouble extensive engineering technical personnel. In the conventional construction technique, the method of welding or binding (certain structures cannot be bound) is always adopted. The construction efficiency is low and is affected by the climate greatly, the labor intensity is large, and the quality is very difficult to ensure. The technique consists of the steps of preparatory work, taper thread processing and manufacturing, reinforcing cage manufacturing and reinforcing cage mounting, wherein the step of the reinforcing cage manufacturing comprises the following steps: hanging the bed section of the reinforcing cage into to a hole; temporarily fixing the top end of the reinforcing cage on a protective barrel; cutting off auxiliary supporting bars in the processof putting the reinforcing cage into the hole for repeated reuse; lifting up the second section of the reinforcing cage to butt with the bed section of reinforcing cage; adjusting an arm lever of a crane, and simultaneously rotating the reinforcing cage so that main bars corresponding to the two sections of the reinforcing cages are butted together; and using a torque wrench to screw down sleeves.The technique is applied to bridge constructions.

Description

Technical field: [0001] The invention relates to a steel bar taper thread connection technology. Background technique: [0002] In the construction of bridge engineering, the connection technology and connection quality of steel bars have been perplexing the majority of engineering and technical personnel. In traditional construction techniques, methods of welding or binding (some structures cannot be bound) have been used. The construction efficiency is low, it is greatly affected by the climate, the labor intensity is high, and it is difficult to guarantee the quality. Invention content: [0003] The object of the present invention is to provide a kind of reinforcement tapered thread connection technology that improves labor efficiency. [0004] Above-mentioned purpose realizes by following technical scheme: [0005] Reinforcement taper thread connection technology, its composition includes: preparatory work, taper thread processing manufacture, reinforcement cage man...
