A high-mark concrete intercepting structure based on a beam-column joint air bag

Abstract

The utility model relates to the field of building construction, concretely is a kind of beam-column joint high-grade concrete intercepting structure based on air bag. It includes air bag body, fin and magnetic attraction plate;Air bag body inside hollow, top end opening, air bag body periphery has multiple communication holes, and is communicated hollow fin one-to-one by communication hole;Magnetic attraction plate is evenly arranged even number in the annular air bag body inner wall, and the magnetism of two adjacent magnetic attraction plates is opposite, in initial state, multiple magnetic attraction plates are sequentially attracted and shrink air bag body inward, when inflating in air bag body, air bag body expands and separates multiple magnetic attraction plates from magnetic attraction contact.The utility model utilizes the magnetic attraction between magnetic attraction plate to quickly shrink air bag body and exhaust, also convenient to insert the air bag body after shrinkage into gap, then inflate, air bag body and fin can further improve the limiting effect after inflation, not easy to slip.

Claims

1. A high-grade concrete interception structure for beam-column joints based on airbags, characterized in that, include: The airbag body (1) is hollow inside, open at the top, and has multiple connecting holes (3) on the outer periphery, and hollow fins (2) are connected one-to-one through the connecting holes (3).
