[0005] Furthermore, the installation assembly includes an installation frame, which is a U-shaped frame and has a pressure plate inside. A threaded rod that passes through the side wall of the installation frame is rotatably installed on one side of the pressure plate. The threaded rod is threadedly connected to the side wall of the installation frame and has a handwheel fixedly connected to one end.

[0006] Furthermore, two limit blocks are fixedly connected to one side of the pressing plate, and a sliding groove matched with the limit blocks is provided on the inner wall of the installation frame.

[0007] Furthermore, one end of the fixing tube is threadedly connected with two bolts, and the movable rod is fixed inside the fixing tube by the bolts.

[0008] Furthermore, one end of the movable rod is fixedly connected with an ear plate, and the ear plate is mounted on the fixing frame by bolts.

[0009] Furthermore, both ends of the folding guardrail are connected with positioning bars, and the two positioning bars are respectively installed on the vertical plate and the fixing frame by bolts.

[0010] The beneficial effects of the utility model are that the device can be installed on a balcony or an elevator shaft through the installation assembly, the cooperation of the door panel and the folding guardrail can prevent workers from falling from the building, and the setting of the door panel makes it easy for workers to pass through the balcony for construction or enter and exit the elevator shaft for construction, and the utility model is highly practical.

DETAILED DESCRIPTION

[0016] Embodiment 1: A safety anti-falling device for building construction, including a fixed frame 1, which is an inverted U-shaped frame, and a door panel 2 is installed on one side of the interior thereof through a hinge, vertical plates 3 are symmetrically arranged on both sides of the fixed frame 1, one side of the vertical plate 3 is fixedly connected to two installation components 4, and the other side is fixedly connected to two fixing tubes 5, a movable rod 6 is inserted into the inside of the fixing tube 5, one end of the fixing tube 5 is threadedly connected to two bolts, the movable rod 6 is fixed to the inside of the fixing tube 5 by bolts, one end of the movable rod 6 is fixedly connected to an ear plate 8, the ear plate 8 is detachably mounted on the fixed frame 1 by bolts, a folding guardrail 7 is installed on one side of the vertical plate 3 between the two fixing tubes 5, both ends of the folding guardrail 7 are connected to positioning strips 9, and the two positioning strips 9 are detachably mounted on the vertical plate 3 and the fixed frame 1 by bolts.

[0017] By adjusting the depth of the movable rod 6 inserted into the fixing tube 5, the distance between the fixing frame 1 and the vertical plate 3 can be adjusted. When the distance between the fixing frame 1 and the vertical plate 3 changes, the folding guardrail 7 is synchronously extended and retracted, so that the device can be applied to different balconies or elevator shafts. The door panel 2 can facilitate construction workers to pass through the balcony or enter the elevator shaft for construction, which is more convenient.

[0018] The mounting assembly 4 includes a mounting frame 41, which is a U-shaped frame and has a pressure plate 42 inside. A threaded rod 43 that passes through the side wall of the mounting frame 41 is rotatably mounted on one side of the pressure plate 42. The threaded rod 43 is threadedly connected to the side wall of the mounting frame 41, and a hand wheel 44 is fixedly connected to one end of the threaded rod 43. Two limit blocks 45 are fixedly connected to one side of the pressure plate 42, and a slide groove that is compatible with the limit block 45 is opened on the inner wall of the mounting frame 41.

[0019] The installation frame 41 is clamped on the balcony or the wall of the elevator shaft, and the threaded rod 43 is rotated by the hand wheel 44, so that the threaded rod 43 drives the pressing plate 42 to move, and the installation and fixation of the device can be achieved through the cooperation between the pressing plate 42 and the installation frame 41. The cooperation between the limit block 45 and the slide groove can prevent the pressing plate 42 from rotating.

[0020] In specific use, a vertical board 3 can be fixed on a balcony or an elevator shaft through the installation frame 41. By adjusting the depth of the two movable rods 6 inserted into the fixed tube 5, the installation position of the fixed frame 1 can be adjusted. Opening the door panel 2 allows construction workers to pass through the balcony for construction or enter and exit the elevator shaft, which is more convenient.
