As shown in Fig. 2 a, Fig. 2 b, first, make special stock 3, in order to the position of fixing crab-bolt 1 system, strengthen its stability, crab-bolt is welded on stock, reduce the concreting impact on its position。
Before civil engineering unit completes reinforcing bar side bundle, the stock completed in advance and crab-bolt are measured by on-the-spot reality, is seated to and specifies position, and carry out reinforcement measure and finished product protection。
The shortcoming of prior art two:
First: when pouring into a mould concrete, due to the character of concrete construction technology and stock, being subject to concrete impulsive force bottom crab-bolt, relative displacement can occur in crab-bolt upper end；
Second: the adjustable space of steel column bottom bolts reserving hole is less, after crab-bolt top is subjected to displacement, it is more difficult to meet subsequent construction requirement；
3rd: can only bury underground before reinforcing bar binding on working procedure。If reinforcing bar binding completes, just cannot bury underground；
4th: the follow-up protection to crab-bolt screw thread is comparatively inconvenient。
