[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A protective device is provided on an operating frame of a non-full shear wall elevator shaft, the operating frame including vertical poles provided in the elevator shaft and horizontal poles provided between the vertical poles, the vertical poles are separated at the four inner corners of the elevator shaft, the horizontal poles are connected between the vertical poles by fasteners, and the four horizontal poles are connected end to end to form a rectangular space, characterized in that the horizontal poles are arranged at a certain distance from the inner wall of the elevator shaft to form a template installation working surface, the protective device includes a protective grille covered on the rectangular space and a protective sheet detachably connected to the horizontal pole, the protective grille is a two-fold grille, including two grille units connected by hinges, the four sides of the protective grille are overlapped on the horizontal pole, one end of the protective sheet is hingedly connected to the horizontal pole, and the other end is overlapped on the top surface of the template or structure, the length of the protective sheet is adapted to the length of the horizontal pole, and the width is greater than the distance between the horizontal pole and the elevator shaft wall.

[0007] Further preferably, the protective grille and the protective sheet are both formed by welding C8 steel bars.

[0008] Furthermore, the protective sheet is provided with L-shaped connectors at intervals along the bottom plate along its length direction. Correspondingly, an insert ring is provided on the cross bar at a position corresponding to the L-shaped connector. The transverse portion of the L-shaped connector is inserted into the insert ring and limited by a nut.

[0009] Furthermore, a blocking frame is provided at the joint between the two grille units and below the hinge.

[0012] Compared with the prior art, the present invention has the following characteristics and beneficial effects:

[0013] The present application adopts the elevator shaft frame flap protective plate, which is installed after the elevator shaft frame of each floor is erected. When the carpenters remove the formwork and move to the upper floor or reinforce the shear wall formwork, the protective plate is flipped up without affecting the material transportation and reinforcement operations. During other processes such as steel bar binding and formwork installation, the flap is in a horizontal protective state, which can provide effective protection. The protective grille is used instead of the woven mesh for easy turnover, and the protective grille is designed to be folded in two, which is convenient for flipping up or down the grille unit to form a temporary passage.

[0018] In order to make the technical means, innovative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below.

[0019] The utility model relates to a protective device provided on an operating frame of a non-full shear wall elevator shaft. The operating frame includes vertical poles provided in the elevator shaft and cross bars 1 provided between the vertical poles. The vertical poles are separated at the four inner corners of the elevator shaft. The cross bars 1 are connected between the vertical poles by fasteners. The four cross bars 1 are connected end to end to form a rectangular space. The cross bars 1 are arranged at a certain distance from the inner wall of the elevator shaft to form a template installation working surface. The protective device includes a protective grille 2 covered on the rectangular space and a protective sheet 3 detachably connected to the cross bars 1. The protective grille 2 is a two-fold grille, including two grille units 22 connected by hinges 21. The four sides of the protective grille 2 are overlapped on the cross bars 1. One end of the protective sheet 3 is hingedly connected to the cross bars 1, and the other end is overlapped on the top surface of the template or structure. The length of the protective sheet 3 is adapted to the length of the cross bars 1, and the width is greater than the distance between the cross bars 1 and the wall of the elevator shaft. The protective grille 2 is designed as a two-fold grille. In an emergency, the grille can be flipped up and down to provide up and down space for workers without dismantling the grille.

[0020] As a preferred embodiment of the present application, the protective grille 2 and the protective sheet 3 are both formed by welding C8 steel bars, that is, by welding steel bars discarded on site.

[0021] As a preferred embodiment of the present application, L-shaped connectors 4 are provided at intervals along the bottom plate of the protective sheet 3 in the length direction. Correspondingly, an insert ring 5 is provided at a position corresponding to the L-shaped connector 4 on the cross bar 1.
