Device for preventing reserved expansion joint notch from being blocked
The invention relates to the technical field of building construction, in particular to a device for preventing a reserved expansion joint notch from being blocked. The device comprises a gravity sensing device installed below a bridge floor, the lower portion of the gravity sensing device is connected with a pressing plate through a pressing rod, the top of the pressing rod is connected with the gravity sensing device, and the bottom of the pressing rod is connected with the pressing plate; an air pressure chamber is arranged below the pressing plate, a vertically-arranged reset spring is arranged in the air pressure chamber, the left side and the right side of the air pressure chamber are connected with the reserved expansion joint notches through air pressure chamber pipelines, one end of each air pressure chamber pipeline is connected with the air pressure chamber, and the other end of each air pressure chamber pipeline is connected with the corresponding reserved expansion joint notch. Dust, chippings and the like are cleaned away through airflow formed by air pressure, later expansion joint construction is facilitated, other tools are not needed, and the purposes of saving resources and manpower are achieved.
本发明涉及建筑施工技术领域，尤其涉及一种防止预留伸缩缝槽口堵塞装置，包括安装在桥面下方的重力感应装置，所述重力感应装置的下方通过压杆连接有压板，所述压杆的顶部与重力感应装置连接，所述压杆的底部与压板连接；所述压板的下方设有气压室，所述气压室内设有一竖直设置的复位弹簧，所述气压室的左右两侧均通过气压室管道与预留伸缩缝槽口连接，所述气压室管道的一端与气压室连接，所述气压室管道的另一端与预留伸缩缝槽口连接。本发明利用气压形成的气流将灰尘、碎屑等清理掉，不仅利于后期伸缩缝施工，且不需要借助其他工具，达到了节约资源、节省人力的目的。
