Description

Technical Field

[0001] The invention relates to the technical field of construction, in particular to a template reinforcement device for a core area of ​​a column-beam node with good sealing performance. Background Art

[0002] During the reinforcement process of the frame column formwork in the core area of ​​the column-beam node, the traditional reinforcement method is: Method 1, use tension bolts to pass through the column and beam reinforcement density area from one side of the column formwork to the symmetrical side column formwork, and use crescent clips to tension and reinforce the column formwork and main rib steel pipes and secondary rib wood on both sides. The disadvantage of this method is that when the reinforcement of the frame columns and frame beams at the core area node is very dense, and this area is the frame beam reinforcement anchorage area, the main reinforcement and torsional waist reinforcement of the beams on both sides are all staggered together, and the tension bolts cannot pass through the column longitudinal reinforcement and beam staggered reinforcement from one side of the column formwork to the other side of the formwork, so that the column formwork on both sides cannot form tension reinforcement. Method 2, with the help of the overall effect of the top plate supporting the formwork frame around the column and beam core area, use steel pipes or wood to support and reinforce the core area column formwork. This method can be implemented when the core area, that is, the height cross-section of the frame beam is small. When the core area is large, the pressure on the column formwork side is very large during the pouring of column concrete, the density spacing of the top supporting wood is insufficient, and the overall stability cannot be guaranteed. In view of the above problems, the existing equipment needs to be improved. Summary of the Invention
