Detailed description of the invention
The present invention is further described below in conjunction with specific embodiment and accompanying drawing.
The Key technique problem that the present invention will solve is exactly how rapid processing can go out the cylindricality steel reinforcement cage shown in Fig. 1.Four that this steel reinforcement cage comprise along its length long to reinforcing bar 1, connected and composed by multiple stirrup 2.Reinforcing bar along its length also can be more, and such as on four faces of four cylindricalitys, each increase by is long to reinforcing bar 1, then just there are 8 reinforcing bars in length of reinforcing cage direction; The structural strength of steel reinforcement cage can be improved further.
The method of processing this steel reinforcement cage is, first makes the sheet bar-mat reinforcement shown in composition graphs 2,3.Bar-mat reinforcement there is the length of arranging along its length to the stirrup 2 of reinforcing bar 1 and corresponding cylindricality reinforcing cage stirrup position.Existing weldering mesh sheet machine rapid processing can go out continuous print bar-mat reinforcement, is sheared by continuity reinforcement(bar) net and just can obtain required sheet bar-mat reinforcement.And the bar-mat reinforcement specification that weldering mesh sheet machine is processed can adjust flexibly, cut lengths also can be grasped flexibly, and working (machining) efficiency is very high.
Then bar-mat reinforcement is bent into U-shaped shallow shown in Fig. 4, more shallow U-shaped bar-mat reinforcement centre position is bent again structure U-shaped structure, namely as shown in Figure 5 by two ends again to centre bending, bar-mat reinforcement can be made to surround cylindricality as shown in Figure 6.Again the apposition position 3 of reinforcing bar after bending is welded or ties up and just obtain required cylindricality steel reinforcement cage.Or the dark U-shaped bar-mat reinforcement shown in Fig. 2 is directly bent into from centre position as shown in Figure 7.Again the dark U-shaped bar-mat reinforcement two ends shown in Fig. 7 are bent relatively, as shown in Figure 8, also can obtain the cylindricality steel reinforcement cage shown in Fig. 6.Then apposition position 3 is welded and just constitute cylindricality steel reinforcement cage finished product.
