Description

Technical Field

[0001] This utility model belongs to the technical field of building construction safety protection, specifically relating to a drill-free protective railing for edge openings. Background Technology

[0002] Effective protection must be implemented at stairwells, elevator shafts, passageways, reserved openings, and material loading openings in construction projects. Depending on the situation of the opening, measures such as setting up fences, installing protective doors, installing fixed covers, hanging safety nets, and erecting protective sheds should be taken. When protecting openings near the edge, the existing technology usually involves drilling expansion bolts into the wall and then fixing steel pipes for protection. This method requires cutting the steel pipes, resulting in material waste and damage to the wall to some extent. Furthermore, the wall needs to be repaired and the expansion bolts left on the wall need to be removed later, which is a complicated process with low utilization rate. Utility Model Content

A second rectangular tube is slidably connected to both ends of the first rectangular tube and sleeved on the outside of the first rectangular tube. The second rectangular tube has a threaded hole on the same side as the threaded holes of the first rectangular tube. A fastening nut is connected between the threaded holes of the first and second rectangular tubes. A first angle steel is fixedly connected to the inner side of the second rectangular tube. A through-threaded rod is fixedly connected to the first rectangular tube on the side of the first angle steel near the middle of the first rectangular tube. The through-threaded rod is equipped with a positioning component.

[0006] Further specifying, the positioning component includes a second angle steel, and a third rectangular tube is fixedly connected to the side of the second angle steel near the middle of the first rectangular tube. The third rectangular tube is sleeved on the outside of the threaded rod, and the outer end of the third rectangular tube is provided with a nut washer that is threadedly connected to the threaded rod.

[0007] Further specifying, the positioning component includes a positioning plate that is threadedly connected to a through screw, a threaded sleeve is fixedly connected to the center of the positioning plate, and the positioning plate is located on the outside of the structural wall.

[0008] Further specifying, the positioning component includes a nut threadedly connected to a through-thread screw, a rotating cylinder fixedly connected to the inner side of the nut, and a rotating sleeve rotatably connected to a third angle steel.

[0009] Further specified, the first angle steel, the second angle steel, and the third angle steel are located at the inner and outer corners of the opening, respectively.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] By adopting this utility model, the traditional installation method of drilling expansion screws into the wall is avoided, the wall is not damaged, the labor cost of repairing the wall and removing the expansion screws is eliminated, and it can be adapted to different wall thicknesses.

[0012] The guardrail has a reasonable structure, is easy and quick to install and disassemble, has a high reuse rate, saves costs, and reduces labor intensity. Attached Figure Description

[0022] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Example 1: As Figure 1-6 As shown, a drill-free edge protection railing includes a first rectangular tube 1, with multiple threaded holes at both ends of the first rectangular tube 1. A second rectangular tube 2 is slidably connected to both ends of the first rectangular tube 1 and sleeved on the outside of the first rectangular tube 1. The second rectangular tube 2 has a threaded hole on the same side as the threaded hole of the first rectangular tube 1. A fastening nut 21 is connected between the threaded holes of the first rectangular tube 1 and the second rectangular tube 2. A first angle steel 3 is fixedly connected to the inside of the second rectangular tube 2. A through thread 4 is fixedly connected to the side of the first rectangular tube 1 near the middle of the first angle steel 3. A positioning component 5 is assembled and connected to the through thread 4.

[0024] In this embodiment, the two ends of the first rectangular tube 2 and the second rectangular tube 1 are positioned by fastening nuts 21. The distance between the two first rectangular tubes 1 can be changed by changing the position of the fastening nuts 21 on the second rectangular tube 2, thereby fixing the first rectangular tube 1 to openings of different widths without having to cut the length of the first rectangular tube 1 to fit the width of the opening. The first angle steel 3 is abutted against the inner external corner of the structural wall, and the positioning part 5 connected by the threaded rod 4 is used to abut against the outer side of the structural wall, so that the first rectangular tube 1 can be installed between the two sides of the opening. When protecting the opening at the edge, multiple sets of first rectangular tubes 1 can be set along the downhill direction to protect the opening. The first rectangular tube 1 and the second rectangular tube 2 are standard parts and can be purchased directly.

[0025] Reference Figure 1-2 6: In this embodiment, the positioning component 5 is further defined. The positioning component 5 includes a second angle steel 51. A third rectangular tube 52 is fixedly connected to the side of the second angle steel 51 near the middle of the first rectangular tube 1. The third rectangular tube 52 is sleeved on the outside of the threaded rod 4. The outer end of the third rectangular tube 52 is provided with a nut washer 53 that is threadedly connected to the threaded rod 4. In this embodiment, the positioning component 5 is further defined. The third rectangular tube 52 fixes the second angle steel 51. By rotating the nut washer 53, the nut washer 53 can be moved, thereby changing the maximum distance between the first angle steel 3 and the second angle steel 51. By tightening the nut washer 53, the first angle steel 3 and the second angle steel 51 can be tightly fitted to the external corner of the structural wall.

[0026] Example 2: Refer to Figure 3This embodiment further defines the positioning component 5, which includes a positioning plate 54 threadedly connected to the through screw 4. A threaded sleeve is fixedly connected to the middle of the positioning plate 54, and the positioning plate 54 is located on the outside of the structural wall. In this embodiment, by rotating the positioning plate 54, the positioning plate comes into contact with the outer wall, and the threaded sleeve is welded to the middle of the positioning plate 54, thereby realizing the installation of the first rectangular rod 2.

[0027] Example 3: Refer to Figure 4 In this embodiment, the positioning component 5 is further defined. The positioning component 5 includes a nut 55 that is threadedly connected to the through screw 4. A rotating cylinder 551 is fixedly connected to the inner side of the nut 55. A rotating sleeve 58 that is fixedly connected to the third angle steel 56 is rotatably connected to the rotating cylinder 551.

[0028] Reference Figure 1-2 This embodiment provides a detailed description of the positions of the first angle steel 3, the second angle steel 51, and the third angle steel 56. The first angle steel 3, the second angle steel 51, and the third angle steel 56 are located at the inner and outer corners of the opening, respectively.
