The inside-outside direction refers to the inside-outside direction of a building. Conveniently erect promptly like this protective frame, simultaneously, also can provide certain space between protective frame and the prefabricated component of encorbelmenting, this space makes things convenient for constructor to be under construction the prefabricated component of encorbelmenting in balcony, window department of wafing. Preferably, the peg is the U type, and two tip of peg are connected with protection frame's montant detachably, can adopt modes such as bolt and nut or grafting to realize dismantling the connection, and the construction site can adjust the mounted position of peg on protection frame's montant according to actual floor height, has improved external protector's suitability, and when using this external protector in other construction projects, helps improving reusability.
In the technical scheme, the fastening device is an embedded sleeve with an internal threaded hole, and the fastening piece is a bolt matched with the internal threaded hole; or the fastening device is a threaded rod with a thread, and the fastening piece is a nut matched with the threaded rod.
In the above technical scheme, one side of the protection frame facing the outer wall board is provided with a supporting device perpendicular to the outer wall board, and the length of the supporting device in the direction perpendicular to the outer wall board is equal to the distance between the vertical rod of the protection frame and the outer surface of the outer wall board. Therefore, the outer vertical surface of the protective frame and the building outer wall panel can be ensured to be parallel to each other.
In the above technical scheme, the prefabricated overhanging component is at least one of a balcony, a bay window and an air-conditioning plate.
Among the above-mentioned technical scheme, the guardrail is the bridging.
In the technical scheme, the side edge of the protection frame is also provided with a side protection frame facing the external wall panel.
Compared with the existing safety protection device for the assembly type building, the invention has the characteristics of small self weight, simple and convenient installation and the like, solves the structural safety hidden trouble caused by the installation of the externally-hung protection device on the balcony and the bay window, and simultaneously prevents the damage to the prefabricated part when the traditional protection device is installed.
