Temporary plugging device for reserved hole in building construction

LI SHAOMENG

The invention discloses a building construction reserved hole temporary plugging device which comprises a baffle disc and a mounting frame, two connecting shafts in transmission connection are slidably connected to the middle of the baffle disc in a penetrating mode, a worm is fixedly connected to one end of each connecting shaft, and worm wheels rotationally mounted on the mounting frame are connected to the two sides of each worm in a meshed mode. A first supporting leg is fixedly connected between the two worm wheels on each side, the other end of each first supporting leg is rotationally connected with a second supporting leg, and the other end of each second supporting leg is rotationally connected with a third connecting block. The device further comprises a gripper shoe mechanism which is connected with the third connecting block. The first supporting leg and the second supporting leg are driven to move through transmission of the worm gear and the worm, so that the supporting shoe mechanism abuts against the inner wall of a hole, the hole is blocked by the blocking disc, it is guaranteed that the hole can be completely covered by the blocking disc, and the complete shielding effect is achieved.

本发明公开了一种建筑施工预留洞临时封堵装置，其包括挡盘和安装架，所述挡盘中间部位贯穿滑动连接有呈传动连接的两个连接轴，且连接轴的一端固定连接有蜗杆，所述蜗杆的两侧均啮合连接有与安装架呈转动安装的蜗轮，且每侧的两个蜗轮之间固定连接有第一支撑腿，所述第一支撑腿的另一端转动连接有第二支撑腿，且第二支撑腿的另一端转动连接有第三连接块；还包括撑靴机构，所述撑靴机构与第三连接块相连接。本发明通过蜗轮蜗杆的传动带动第一支撑腿和第二支撑腿运动，以使撑靴机构抵住洞内壁，从而使挡盘封堵洞口，保证洞口能够被挡盘完全覆盖，达到完全遮挡的效果。
