Description

Prevention of seepage water nut and split screw assembly

Technical Field

The invention relates to the technical field of construction engineering construction, in particular to a water seepage prevention nut and a split screw assembly.

Background

In concrete building construction, in order to maintain the shape and thickness of a wall body, a split screw device is used to control the distance between the panels. However, due to the cost problem, after the construction is completed, the split screw rod needs to be taken out for reuse, so that a through split screw rod hole is reserved in the concrete wall, later-stage labor and material resources are needed for waterproof plugging treatment of the hole, and the problem that the wall body is subjected to water seepage due to construction negligence or different combination strength and expansion and contraction coefficients of two materials cannot be avoided. Although the opposite-penetrating screw device in the technology of patent application number CN2015201146477 also has a good water seepage prevention function, the whole screw needs to be left in concrete, the material consumption is large, a waterproof block needs to be welded, and long nuts need to be connected to two ends of the screw, so that the processing amount is large, the cost is higher, and the construction is complex. For example, the through screw of patent application No. CN2011203587141 also has a water seepage prevention function, but besides the above disadvantages, there is a risk caused by aging of waterproof materials.

Among present aluminum mould board system, the part has introduced the pulling-on piece and has replaced the split screw, though the wall body infiltration problem has been solved, during nevertheless concreting, the not good control of the hourglass thick liquid problem that the gap between pulling-on piece and the template leads to, heavy wall, post position still will cooperate and use together to wearing the screw to produce building rubbish because of the disconnected tail of pulling-on piece, moreover, because the pulling-on piece breakpoint is close to the wall body surface, if later stage rust-resistant treatment is not in place, let rust stain ooze wall surface influence fitment effect very easily, lead to bigger loss.
