Further, the rectangular steel plates height is identical as gate steel plate, and width is identical as male steel edges of boards, in rectangle steel
Prepared screw-bolt hole above plate, is bolted for two neighboring tension slot groove punching block.
Further, material rigidity used in the Cast-in-situ Beam transverse prestress tension slot groove punching block is big, is unlikely to deform, facilitates steel
Twisted wire is fixed on tensioning, works convenient for subsequent sealing off and covering anchorage.
Compared with the utility model Cast-in-situ Beam transverse prestress tension slot groove punching block is template used with traditional construction, have following
Advantage:
1, the rigidity of structure is big just now, is unlikely to deform, and it is smooth to pour face.
2, facilitate the tensioning of steel strand wires and the placement of jack, the safety is improved.
3, the number of turnover is more, and installation speed is fast, and demoulding is easy, and reduces construction cost.
4, the lamellate lower concrete of tension slot groove of completion is poured, when subsequent sealing off and covering anchorage need to only found side form, facilitate sealing off and covering anchorage.
5, it fixes convenient for lateral steel strand wires and tensioning, facilitates subsequent sealing off and covering anchorage, applied especially suitable for Cast-in-situ Beam transverse prestress
Work.
