Description

Technical Field

[0001] The utility model relates to the technical field of elevator shaft protection structures, in particular to a protection structure for elevator shafts in building construction. Background Technique

[0002] In building construction, the protection of elevator shafts is of utmost importance for construction safety. The protection measures in elevator shafts include hard protection and soft protection. Among them, soft protection is the horizontal net protection made of large-mesh nets. When installing the horizontal net, it is usually installed on the scaffolding and then fixed to the wall inside the elevator shaft through expansion bolts. This is not only inconvenient to operate but also damages the wall, and it is difficult to disassemble later. For example, the patent with the publication number CN218988510U discloses a protection structure for elevator shafts in building construction, which includes a fixed plate placed on the ground, and the fixed plate is connected to the protection plate inside the elevator shaft. A protection net is fixedly arranged inside the protection plate. Main lifting rings are evenly arranged on the upper surface of one side of the protection plate. A main counterweight block is fixedly connected to the position close to the center of the upper surface of the fixed plate. Auxiliary counterweight blocks are arranged on both sides of the main counterweight block. This device fixes the protection plate through counterweight blocks and lifting rings. However, since the protection net is directly fixedly connected to the protection plate, the protection net is easily damaged, making it difficult to replace the protection net each time, and the overall replacement cost is relatively high.

[0003] Therefore, the utility model provides a protection structure for elevator shafts in building construction. Content of the Utility Model

[0005] To achieve the above purpose, the utility model is realized through the following technical solutions: A protection structure for elevator shafts in building construction includes a slide rail fixed to one side of the elevator shaft. A plurality of elevator openings are provided on the side surface of the elevator shaft. A protection plate is slidably fitted in the slide rail, and the protection plate corresponds to the elevator openings. A first connection block is fixed on one side of the slide rail. A first telescopic rod is fixed inside the first connection block. Second telescopic rods are installed at both ends of the first telescopic rod. A third telescopic rod is installed between the two second telescopic rods. A support rod is installed between the first telescopic rod and the third telescopic rod. A hanging net is placed between the first telescopic rod, the second telescopic rod and the third telescopic rod.

[0006] Further, second connection blocks are fixed to both ends of the second telescopic rod, and the end of the first telescopic rod and the end of the third telescopic rod are both fixedly connected to the second connection blocks.

[0007] Further, a net hanging rod is fixed to the second connection block, and the net hanging rod corresponds to the hanging net.

[0008] Further, extension plates are fixed to the lower sides of the first connection block and the second connection block, and the extension plates correspond to the support rods.
