Sealing plug for plugging screw hole
The invention relates to building construction, in particular to a sealing plug for plugging a screw hole. The screw rod is arranged in a wall body, the outer end of the screw rod and the nut are retracted into the wall body, the outer end of the screw rod hole is of a taper hole structure, a sealing plug is installed at an outer end opening of the screw rod hole, the sealing plug is made of a high polymer material, the sealing plug is of a frustum structure, and the outer conical surface of the sealing plug is connected with the inner wall of the screw rod hole in a sealed mode; an inner blind hole structure is arranged in the center of the inner end of the sealing plug and is a three-stage stepped hole, a first-stage stepped hole of the inner blind hole structure is matched with a flat gasket of the screw rod, a second-stage stepped hole of the inner blind hole structure is matched with a nut of the screw rod, and a third-stage stepped hole of the inner blind hole structure is matched with threads at the outer end of the screw rod. The sealing plug is simple in structure and convenient and fast to install, the sealing plug is tightly attached to concrete, and the risk of cracking of traditional mortar plugging is avoided.
本发明涉及建筑施工，特别是一种螺杆孔洞封堵用密封塞。螺杆置于墙体内，螺杆的外端和螺母缩进墙体内，螺杆孔洞的外端为锥孔结构，螺杆孔洞的外端口安装有密封塞，所述密封塞的材质为高分子材料，所述密封塞为锥台结构，密封塞的外锥面与螺杆孔洞的内壁密封连接；密封塞内端的中心设有内盲孔结构，内盲孔结构为三级阶梯孔，内盲孔结构的一级阶梯孔与螺杆的平垫配合，内盲孔结构的二级阶梯孔与螺杆的螺母配合，内盲孔结构的三级阶梯孔与螺杆外端螺纹的配合。本发明结构简单，安装方便快捷，密封塞与混凝土间贴合紧密，避免了传统的砂浆封堵开裂的风险。
