Description

Technical Field

[0001] This utility model relates to the field of elevator protection technology, and in particular to a drilling-free, modular elevator opening protection device. Background Technology

[0002] In the construction industry, safety during construction is of paramount importance. However, it is inevitable that there will be openings near the edges during construction, and elevator shaft openings are one of them. Elevator shafts are often idle before elevator installation. In order to ensure construction safety and prevent accidents, protective facilities need to be installed at elevator door openings.

[0003] In the process of protecting elevator openings, traditional construction methods use rivets or expansion bolts to fix the prefabricated guardrails to the elevator opening. Using rivets or expansion bolts is time-consuming and labor-intensive, and it damages the concrete structure; if the elevator guardrail needs to be temporarily removed due to process requirements, it is difficult to restore the original state and requires re-drilling; the prefabricated guardrails are large in area, making them inconvenient to transport.

[0004] Based on this, a drilling-free, modular elevator opening protection device is proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model proposes a drilling-free, modular elevator opening protection device.

[0006] The technical solution to achieve the purpose of this utility model is: a drill-free, assembled elevator opening protection device, including the opening, and also including;

[0007] A fixed slide rail is composed of square steel, C-shaped steel, angle steel, and connecting bolts. One side of the fixed slide rail has the end of the C-shaped steel welded to multiple angle steels. Each of the angle steels has a threaded hole through it on one side. A rubber pad is attached to the end of the C-shaped steel. The back of the fixed slide rail has the end of the square steel welded to the corresponding multiple angle steels. A rubber pad is attached to the end of the square steel. The front and back of the fixed slide rail are fastened together by connecting bolts.

[0008] A standard component baffle, wherein two T-shaped steels are fixedly welded to one side of the standard component baffle.

[0009] In some embodiments, the two T-shaped steels are slidably connected to the inner wall of the corresponding C-shaped steels, and the T-shaped steels and C-shaped steels are adapted to each other.

[0010] In some embodiments, the inner wall of the C-shaped steel is slidably connected to two slotted clips, each of which has a threaded hole on one side, and the inner wall of each threaded hole is threaded with a fastening bolt.

[0011] In some embodiments, one end of each of the two fastening bolts is fixedly connected to a rubber clamping head.

[0012] In some embodiments, ...

[0013] Compared with existing technologies, the significant advantages of this invention are:

[0014] Firstly, this utility model uses a fixed slide rail with C-shaped steel ends welded to four angle steels on the front, with holes left in the angle steels for bolts to pass through. Rubber pads are attached to the ends of the C-shaped steels to increase friction with the wall. The back of the fixed slide rail is made of square steel ends welded to four angle steels, with holes left in the angle steels for bolts to pass through. Rubber pads are attached to the ends of the square steels. The front and back of the fixed slide rail are fastened together with connecting bolts, ensuring a reliable connection to the shear wall. This replaces the traditional method of using rivets or expansion bolts to fix the finished guardrail to the elevator opening, which is time-consuming and labor-intensive.

[0015] Secondly, the standard baffle in this utility model can slide along the C-shaped steel. After sealing the elevator opening with several standard baffles, the baffles are fixed with fixing clips to prevent movement. Attached Figure Description
