Anchorage is anchored, and is accessed reinforcing bar respectively on both sides by butt joint.
(3) due to the reinforcing bar inconvenience rotation by anchoring at two ends, utilize positive and negative threaded ferrule to both sides bar connecting stretch-draw, change
Become reinforcement stresses (making it produce certain pre-tensile stress).
(4) welded reinforcement truss mould plate, utilizes the reinforcing bar with pre-tensile stress as the top boom of girder system so that it is to bear mould
The weight of plate；Described template uses pre-manufactured steel board.
(5) concreting is completed.
The present invention has the advantages that relative to prior art
1, by pre-buried anchorage and pipeline mode for after water reinforcing bar at floor and provide and access and anchoring, have low cost, consumption
Time short feature, be possible not only to reduce using the time used by bar planting and the step of loaded down with trivial details specialty, it also avoid chisel with pre-simultaneously
Stay the fatigue strength loss hidden danger of reinforcing bar, there is obvious economy and convenience.
2, the tension by making both sides reinforcing bar generation certain with the sleeve connection of positive and negative screw-thread does steel bar girder mould after balance
The compressive stress (being similar to prestressing force) that the reinforcing bar of top boom is caused is served as during plate.Be no longer necessary to set up other such as angle steel, I-shaped
The extra support of steel etc..Greatly reduce the workload of workmen.
3, due to the method template set up dependence is the pre-tensile stress of this layer of reinforcing bar, it is possible to construction in layer, without waiting for
Maintenance, it is possible to achieve rapid construction.
4, the present invention is economical and practical, simple in construction, and stress is clear and definite, and method easily operates, and the suitability is strong.
