2. And additionally arranging a cover plate on the hole to plug the hole. Install the apron additional on the hole, the shutoff hole: the plugging cover plate is generally made of a wood springboard or a steel plate on site. Constructors are convenient to draw, and sometimes temporary materials are used for plugging, so that great potential safety hazards are caused. In the construction process, a constructor often removes the plugging cover plate, and sometimes does not restore the plugging of the hole in time after the lifting by using tools and materials of a floor hole lifting machine or penetrating a cable. Therefore, the cover plate is additionally arranged on the hole, so that the operation cannot be standardized, and serious potential safety hazards can be caused. If a standard steel cover plate is required to be manufactured, the cover plate cannot be manufactured in a standardized manner and cannot be reused due to the fact that the sizes of holes are different, and cost is high. Because of the existence of the cover plate, the holes cannot be utilized, and the influence on the installation is large.

Therefore, the existing protective device for the reserved hole in building construction has the problems of single structure fixation, high cost, small application range and the like; meanwhile, the traditional fence protection mode is adopted, so that the construction activity space is reduced, the walking of workers and the development of other work are influenced, the carrying is difficult, the storage cannot be realized, and the occupied space is large.

In practical use, the telescopic device 2 is composed of a rod-shaped structure, a strip-shaped structure or a square structure and the like which can slide with each other.

Specifically, the suspension portion 11 of the fixing module 1 is L-shaped, and includes a horizontal portion 111 engaged with the upper edge of the hole (upper surface of the floor slab) and a vertical portion 112 engaged with the inner side of the hole (side surface of the floor slab), and in actual use, the horizontal portion 111 and the vertical portion 112 are provided with a friction layer (not shown) for increasing friction, such as a fine protrusion, on the surface contacting with the hole (floor slab). The rail portion 111 mainly serves as a hook. The vertical section part 112 of the fixed module 1 is provided with a first connecting part 12 facing the center of the hole for connecting with the end of the telescopic device 2. The first connecting part 12 is a U-shaped groove structure; the telescopic device 2 is of a rod structure, a bar structure or a square structure, and the two ends of the telescopic device are connected with the first connecting part 12 in a detachable structure. The first connection portion 12 may be provided at upper, middle and lower portions of the middle position of the vertical section portion 112. The hanging portion 11 may also be other structures capable of hanging on the edge of the hole, such as a common hook with a single hook or a hook with a plurality of barbs, and the connection manner between the first connection portion 12 and the expansion device 2 may also be a threaded connection or a snap connection.

When in actual use, the fixing module 1 is formed by welding a plurality of steel plates or integrally formed by pouring, and has the advantages of simple structure, low manufacturing cost and reliable use. The combined type protection device formed by adopting a plurality of fixed modules and a detachable structure can be suitable for reserved holes with different shapes and sizes, can effectively improve the mounting protection capability and simultaneously has the technical effects of simple and convenient mounting and dismounting and flexible and convenient use; meanwhile, the method can be manufactured in a standard factory and produced in batch, and the manufacturing cost is low; the utility model can be disassembled and stored after use, and can be repeatedly used for a long time and occupy small space.

As shown in fig. 1 and 4, in order to increase the stability between the first connecting portion 12 and the telescopic device 2, a stop baffle 121 for stopping is arranged at the upper end opening of the U-shaped groove structure; after the telescopic device 2 is connected with the first connecting portion 12, if the protecting device is subjected to a downward force from the top in the later use process, the telescopic device 2 is prevented from sliding due to the external force by the stop baffle 121 when the telescopic device 2 is moved to a certain extent, so that the telescopic device slides from the U-shaped groove structure of the first connecting portion 12. In this embodiment, stop baffle 121 is welded to the vertical section 112 and the upper end opening of the U-shaped channel, where it is located for ease of installation. When in actual use, the U-shaped groove structure can be arranged in the middle or at the front end of the opening at the upper end of the U-shaped groove structure.
