The external protective frame 150 may include a frame body composed of an inner cross bar 151, an outer cross bar, a longitudinal cross bar, a vertical bar, and an inclined bar, and a protective net 153.
And a controller 160 connected to the screw motor 112 of each of the L-shaped wall elements 110 and to the lifting motor 142 of each of the lifting mechanisms 140.
According to the assembly type building intelligent lifting external hanging protection frame 100 provided by the embodiment of the invention, the L-shaped wall connecting piece is attached to the wall surface 200 and is used for supporting the construction load of the external hanging protection frame 150; the longitudinal cross bar 152 is attached to the rack 120 through a gear 143 connected with the lifting motor 142, and is used for supporting the self-weight load of the external protective frame 150 during the lifting process.
Referring to fig. 12 and 15, in order to implement safety monitoring on the load during installation and construction of the external hanging protection frame 150, in the assembly type intelligent lifting external hanging protection frame 100 according to the embodiment of the present invention, the L-shaped wall connecting member 110 further includes a pressure sensing plate 115 disposed on the upper surface of the steel backing beam 111, the inner cross bar 151 of the external hanging protection frame 150 is lapped on the pressure sensing plate 115 of the L-shaped wall connecting member 110, the pressure sensing plate 115 is provided with pressure sensors 117, and each pressure sensor 117 is connected to the controller 160.
In the intelligent lifting external hanging protection frame 100 for the fabricated building provided by the embodiment of the invention, the L-shaped wall connecting piece 110 can adopt the following two schemes.
The first scheme is as follows: referring to fig. 12 to 14, the stopper 114 of the l-shaped wall connecting member 110 is integrally connected to the steel backing beam 111 to form a first member, and the screw motor 112 is integrally connected to the screw 113 to form a second member. The steel pad beam 111 is provided with a first through hole 1111 which is communicated with the cavity of the steel pad beam and is used for extending the screw 113.
Scheme two is as follows: referring to fig. 15 to 17, the steel backing beam 111 of the L-shaped wall connecting member 110 is a first component, the stopper 114, the screw motor 112 and the screw 113 of the L-shaped wall connecting member 110 are integrally connected to form a second component, the second component penetrates through the first component and is distributed at two ends of the first component, the spring 116 is connected between the pressure sensing plate 115 and the screw motor 112, and at this time, the two ends of the steel backing beam 111 may be respectively provided with a first through hole 1111 and a second through hole 1112 which are communicated with the cavity therein. In the second scheme, the second component is integrally connected, and the outer hanging protection frame 150 is lapped on the steel pad beam 111 of the L-shaped wall connecting piece 110 and is stressed uniformly relatively, so that the moment is small. When no inner cross bar 151 is lapped and pressed on the steel pad beam 111, the pressure sensing plate 115 is bounced under the action of the spring 116, the spring 116 is not in contact with the precession motor 112 of the second component, and thus the second component can be screwed in or out to the first embedded bolt hole 211 and move towards the inside and the outside of the wall surface; when the inner cross bar 151 is pressed against the steel pad beam 111 in a lap joint manner, the pressure sensing plate 115 is in contact with the second module, and transmits the construction load to the second module and then to the interior of the wall of the fabricated exterior wall. Therefore, the load bearing effect of the L-shaped wall connecting element 110 of the second scheme is higher than that of the first scheme.

The overlapping hole of the inner rail 151 passes through the stopper 114 of the L-shaped wall connecting member 110 to overlap the steel backing beam 111 or the pressure sensing plate 115 thereon. Of course, for the purpose of overlapping, the lower surface of the inner rail 151 may be overlapped on the steel backing beam 111 or the pressure sensing plate 115, and the side surface of the inner rail 151 may be overlapped on the stopper 114.
