Description

External protector of assembled building

Technical Field

The invention relates to an external hanging protection system for an assembly type building, in particular to an external hanging protection device for a balcony or a bay window.

Background

At traditional construction site, scaffold and safety protection network are set up usually around the building, prevent that the high altitude from falling thing and protection constructor safety, and it is big to set up work load, and steel pipe, fastener, safety net are in large quantity, and the cost is high to occupy the period of work in the work progress, set up the scaffold and must be in advance or be under construction with main part engineering simultaneously together, make in the installation, the potential safety hazard is many. In the existing assembly type building construction site, due to the fact that most of outer walls are prefabricated, scaffolds and safety protection nets are inconvenient to set up, an externally-hung safety protection device with a construction platform is usually adopted in the existing assembly type building construction site, for example, the invention patent (CN 104131688B) discloses an externally-hung type operation platform special for an assembly type building, the operation platform is connected to the prefabricated outer walls through the construction platform, and workers stand on the construction platform when the outer walls are constructed. On one hand, due to the existence of the construction platform, the safety protection device is heavy, the construction platform and the protective net are in an overhanging state, when a constructor constructs the construction platform, all gravity is intensively acted on the joint of the construction platform and the prefabricated outer wall, so that the acting force is excessively concentrated, the safety protection device is easy to lose stability, and a large potential safety hazard exists; on the other hand, because the dead weight of the safety protection device is large, when the safety protection device is erected on overhanging components such as balconies, bay windows and the like, the structural safety of the balconies and the bay windows is seriously influenced. In addition, the traditional protection devices at balconies, bay windows and the like are all in a form of erecting steel pipes into supports, the number of accessories required for erecting the protection devices is large, the construction is time-consuming and labor-consuming, and the appearance is difficult to achieve neatness and attractiveness; and still need use the inflation screw to install during the installation, the inflation screw causes destruction to prefabricated component very easily, influences the safety of building.

Disclosure of Invention

Aiming at the problems of the existing safety protection device, the invention provides the assembled building external hanging protective net, which cancels a construction platform of the traditional assembled building safety protection device, greatly lightens the self weight of the external hanging protective net, reduces the load of overhanging components such as balconies, bay windows and the like, ensures the structural safety of the balconies and the bay windows, further improves the current situation that the load is concentrated on the construction platform, and improves the stability of the external hanging protective net.

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.
