Description
Technical Field
The utility model belongs to the technical field of the construction, concretely relates to shear force wall screw rod hole plugging device.
Background
In the construction of the shear wall in a house, the plugging of the screw hole is a key point and is also a difficult point, and the traditional plugging of the screw hole adopts foaming agents and other gap filling materials, so that the construction is inconvenient, the water seepage of the wall body is caused due to poor waterproof effect, and the site is disordered due to the accumulation of materials, and the environment is not protected. In addition, the existing building is constructed by adopting an aluminum alloy template for high quality requirements, the diameter of the screw hole is large relative to that of a wood mould, the traditional plugging mode is adopted, the outer wall has the risk of leakage, and the hollowing of the inner wall surface is increased. For this reason, it is necessary to develop a shear wall screw hole plugging device capable of solving the above problems.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a shear force wall screw rod hole plugging device.
The utility model aims at realizing like this, including locating the precast concrete awl in the screw rod hole, be equipped with waterproof cement paste layer between screw rod hole inner wall and the precast concrete awl.
The utility model has the advantages that: the utility model discloses a precast concrete awl cooperation waterproof cement paste layer has replaced the tradition and has adopted shutoff materials such as foamer to carry out the way of shutoff to shear force wall screw rod hole, and precast concrete awl construction is convenient, and the shaping is effectual, has solved the easy seepage problem of outer wall to and its way of regularization construction has also realized green's purpose; the utility model discloses still can cooperate shutoff dish and seal closure to be under construction, not only be favorable to promoting screw hole entrance to a cave shutoff effect, construction convenience moreover.
