Description

Detachable reusable wall template leakage-proof lower hanging ball fixing device Technical Field The utility model relates to the technical field of building tools, in particular to a detachable and reusable wall form leakage-proof under-slurry hanging ball fixing device. Background With the continuous rise of social aesthetic standards, the requirements of the building are not only limited to safety performance, applicability performance and economical performance, but also pay more attention to the aesthetic appearance of the building. However, common quality common problems (such as mold expansion, slurry leakage, displacement, etc.) seriously affect the impression effect of the concrete structure during the construction of the main structure. The traditional template construction process is easy to have the problems of infirm reinforcement, positioning deviation and the like at the joints of the upper layer and the lower layer, so that the joints are staggered and the slurry is leaked, the appearance quality is affected, and the structural integrity is possibly reduced. At present, part of construction units adopt a pre-buried foot locking screw (lower hanging ball) technology to optimize the fixing mode of the outer wall and the stair well template. According to the technology, the lower ball hanging component is buried in the lower layer structure in advance, so that the upper layer template can be positioned accurately and fixed firmly, and the joint quality is controlled effectively. However, the existing lower ball hanging device still has the following problems in construction: the traditional foot locking screw rod needs to cut exposed parts after concrete pouring is completed, so that steel is wasted, the traditional foot locking screw rod cannot be reused, and construction cost is increased. The end of the cut screw rod is easy to rust, the durability of the wall body is affected, the cutting surface can damage the surface of concrete, the later repair workload is increased, a large number of waste reinforcing steel bars are difficult to recycle, the environment-friendly construction requirement is not met, and the construction waste treatment burden is increased. Disclosure of utility model The utility model aims to solve the defects in the prior art, and provides a detachable and reusable wall template leakage-proof under-slurry hanging ball fixing device.
