[0032] Example
[0033] This embodiment provides a safety net for chimney outer tube construction, referring to Figure 1 and Figure 2 As shown, it includes a fixing member, a first steel wire rope 1, a second steel wire rope 2, and a net 3. There are multiple fixing members, each of which is arranged along a circular path and fixed to the chimney inner wall. In this embodiment, the chimney inner wall is provided with a corbel 4, which is arranged along the chimney's circumference, and the fixing member is mounted on the corbel 4. The corbel 4 is an inherent structure of the chimney itself and is used to mount other structures on the chimney inner wall. Installing the fixing member on the corbel 4 does not damage the chimney's interior or require the installation of additional structures, thus reducing workload.
[0034] The ends of the first steel wire rope 1 are connected to different fixings via rope clamps. Specifically, one first steel wire rope 1 corresponds to two fixings, ensuring that the first steel wire rope 1 is stretched straight and its ends are connected to the fixings via rope clamps. Multiple first steel wire ropes 1 are arranged in a staggered arrangement in both the horizontal and vertical directions, dividing the interior of the chimney into multiple unit grid areas 5.
[0035] The second steel wire rope 2 passes through each fixing member in sequence along the annular path of the chimney inner wall to form a ring shape, so that the second steel wire rope 2 is arranged along the annular direction of the chimney inner wall.
[0036] Reference Figure 1As shown, multiple nets 3 are arranged in a one-to-one correspondence within the unit grid area 5, and the edges of the nets 3 are tied and secured to the first steel wire rope 1. By arranging multiple nets 3 in conjunction with the first steel wire rope 1, the overall impact resistance is improved, enhancing the buffering effect against falling objects from high altitude. The nets 3 at the edge of the cylinder wall are tied to the second steel wire rope 2, reducing the gap between the nets 3 and the edge of the cylinder wall and improving the protection effect at the edge.
[0037] Specifically, a plurality of unit grid areas 5 arranged in the horizontal and vertical directions are formed by staggered arrangement of multiple steel ropes. In order to facilitate the passage of the construction elevator, an opening 9 is set on the net 3 corresponding to the construction area located in the center of the cylinder wall, so that the construction elevator can pass through the opening 9.
[0038] The present embodiment provides an internal safety net for chimney outer tube construction, which can unload and buffer falling objects from high altitude to protect the protective shed on the ground, thereby improving the overall safety factor of the chimney outer tube construction protection system; steel wire ropes are staggered to form multiple unit grid areas 5 and then the net 3 is tied together, which improves the overall bearing capacity of the safety net, and the installation and layout process is also relatively simple.
[0039] Specifically, refer to Figure 3 As shown, the fixing member includes an expansion bolt segment 61 and a connecting ring segment 62 located on top of the expansion bolt segment 61. The first steel wire rope 1 is connected to the connecting ring segment 62 through a rope clamp, and the second steel wire rope 2 passes through the connecting ring segments 62 of each fixing member in sequence.
[0040] Specifically, in order to further reduce the gap between the net 3 and the inner wall of the chimney, the fixing parts include a main fixing part 6 and a secondary fixing part 7. The main fixing part 6 corresponds to the first steel wire rope 1, that is, one first steel wire rope 1 corresponds to two main fixing parts 6, so that the end of the first steel wire rope 1 is connected to the main fixing part 6. A plurality of secondary fixing parts 7 are provided between adjacent main fixing parts 6, and the second steel wire rope 2 passes through each main fixing part 6 and secondary fixing part 7 in sequence along the annular path of the inner wall of the chimney. By arranging a plurality of secondary fixing parts 7 between adjacent main fixing parts 6 for encryption, the outline of the second steel wire rope 2 is closer to the inner wall of the chimney, and the net 3 at the edge is tied to the second steel wire rope 2, further reducing the gap between the net 3 and the cylinder wall.
[0041] Specifically, in this embodiment, the steel wire rope and the bag net 3 can be tied and fixed with a cable tie, or they can be tied directly with other structures such as a rope belt.
[0042] Specifically, a third steel rope 8 is provided in the middle unit grid area 5. The end of the third steel rope 8 is connected to the first steel rope 1. Multiple third steel ropes 8 are arranged in a staggered manner to form a rope opening aligned with the opening 9. The net 3 located at the center of the cylinder wall is tied to the third steel rope 8. This tightens the opening 9 of the net 3, reducing the gap between the net 3 and the construction elevator.
[0043] Specifically, refer to Figure 4 As shown, the net 3 includes a rope edge 31 and a rope net 32. The rope net 32 comprises multiple cross-arranged ropes, which are tied to the rope edge 31. The rope edge 31 is tied to the first steel wire rope 1 or the second steel wire rope 2. The rope edge 31 is formed into a quadrilateral shape, and the four corners of the rope edge 31 are hooked to the intersecting positions of the first steel wire rope 1 and the second steel wire rope 2 via S-shaped hooks 33. When tying the net 3 to the steel wire rope, the S-shaped hooks 33 are hung at the four corners of the rope edge 31, with one end of the hook 33 hooked to the rope edge 31 and the other end hooked to the intersecting position of the first steel wire rope 1 and the second steel wire rope 2. The net 3 is unfolded and its outline is roughly aligned with the unit grid area 5. It is then tied with a cable tie, improving the construction efficiency of the construction workers. After the net 3 is tied, the hooks can be removed and reused.
[0044] Specifically, in this embodiment, multiple layers of safety nets are arranged in a vertical direction of the chimney and arranged inside the chimney. The position of each layer of safety net can be determined according to the height of the corbels 4 in the chimney.
[0045] Construction method: First, install the fixings on the corbels 4. Then connect the first steel ropes 1 to the main fixings 6. The first steel ropes 1 are arranged in a staggered manner to form multiple unit grid areas 5. The second steel ropes 2 are passed through each fixing in sequence to form a loop. Then, align each net 3 with each unit grid area 5 one by one, and tie the net 3 to the first steel ropes 1 and second steel ropes 2 respectively.
[0046] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0047] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
