DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Embodiment 1:

[0020] like Figure 1-Figure 4 As shown, the insulation structure for the steel column of the steel structure cold storage includes an insulation frame 2, and sealing components 3 are respectively arranged at both ends of the insulation frame 2. The sealing components 3 seal the annular gap surrounded by the insulation frame 2 and the steel column 1 to form an insulation space, and the insulation space is filled with polyurethane foam. The insulation frame 2 includes a plurality of insulation units, and the plurality of insulation units are sequentially connected end to end to form a closed-loop insulation frame 2. The insulation unit includes a first connecting plate 201, and a first supporting plate 204 is connected to the first connecting plate 201. On adjacent insulation units, a second support plate 205 for filling the distance between the two first support plates 204 and a locking component for fixing the two first support plates 204 are arranged between two adjacent first support plates 204.

[0021] Two plugging components 3 are installed on the outside of the steel column 1, and then a plurality of insulation units are installed on the plugging components 3. Due to the different sizes of the steel columns 1, the distances between the two adjacent first support plates 204 are different after the insulation units are installed on the plugging components 3. Some of them will just touch, and some will have a larger spacing. Therefore, the second support plate 205 is fixedly connected between the two adjacent first support plates 204 to fill the gap between the adjacent first support plates 204. Then, the adjacent first support plates 204 are locked together by the locking component to ensure that they will not produce relative displacement. Then, polyurethane foam is filled into the insulation space to form an insulation layer. At this time, the second support plate 205 is squeezed by the polyurethane foam in the insulation layer and pressed against the first support plate 204. Through modular design, a single area can be handled separately during subsequent maintenance without overall disassembly, thereby reducing maintenance costs and improving maintenance efficiency. By setting the second support plate 205, it is possible to cooperate with the first support plate 204 to surround steel columns 1 of different specifications and improve the scope of application.

[0022] Embodiment 2:

[0023] On the basis of Example 1, Figure 2 As shown, the first connecting plate 201 is provided with a connecting sleeve 202, the first supporting plate 204 is provided with a rotating shaft 203, and the connecting sleeve 202 is rotatably connected to the rotating shaft 203. Through the above arrangement, the first supporting plate 204 can be freely rotated to be closed, so that the second supporting plate 205 is conveniently placed between the two first supporting plates 204, thereby improving the installation efficiency.

[0024] like Figure 3 As shown, the locking assembly includes a locking shaft 206 and a threaded rod 209. The locking shaft 206 is rotatably connected to a locking plate 207. A plurality of fixing grooves are provided on the locking plate 207. The fixing grooves cooperate with the threaded rod 209. The threaded rod 209 is threadedly connected to a limiting ring 208. The limiting ring 208 is used to fasten the locking plate 207. The locking shaft 206 and the threaded rod 209 are respectively provided on two adjacent insulation units and two adjacent first support plates 204.

[0025] After the second support plate 205 is placed, the two first support plates 204 are closed, and then the locking plate 207 is moved to press the locking plate 207 onto the threaded rod 209. At this time, the fixing groove is stuck on the threaded rod 209, and then the limiting ring 208 is manually twisted to make the limiting ring 208 press the locking plate 207 tightly, so that the locking plate 207 is fixed, and the two first support plates 204 can no longer be opened; when filling with polyurethane foam, it can also prevent the first support plate 204 and the second support plate 205 from moving abnormally due to the pressure of the polyurethane foam.

[0028] Embodiment 4:

[0029] On the basis of Example 2, Figure 4 As shown, the blocking assembly 3 includes a plurality of blocking units, which are connected end to end in sequence to form a closed loop. The blocking unit includes a second connecting plate 301, a convex blocking plate 304 is installed on one side of the second connecting plate 301, and a concave blocking plate 306 is installed on the other side. A plugging rod 305 is provided on the convex blocking plate 304, and a locking pin 307 is provided on the concave blocking plate 306. According to the specifications of the steel column 1, the depth of the plugging rod 305 inserted into the concave blocking plate 306 is controlled, and then the locking pin 307 is used to lock the plugging rod 305 in the concave blocking plate 306 to ensure that the blocking unit fits the outer wall of the steel column 1 after assembly.

[0030] Working principle: According to the specific specifications of the steel column 1, the size of the plugging component 3 is adjusted to ensure that after the plugging component 3 is installed on the outer wall of the steel column 1, the plugging component 3 is tightly fitted with the outer wall of the steel column 1; then the first connecting plate 201 is installed on the second connecting plate 301, so that the inner side of the first connecting plate 201 fits with the outer side of the second connecting plate 301, and then the first support plate 204 is installed on the first connecting plate 201, and then the second support plate 205 is placed, and then the locking plate 207 is turned, the limit ring 208 is twisted, and the two matching first support plates 204 are fixed together through the locking plate 207, and the installation of the insulation frame 2 and the plugging component 3 is completed. At this time, polyurethane foam is manually filled into the empty insulation space formed by the steel column 1, the insulation frame 2, and the plugging component 3 to ensure that there is no gap in the space, and the polyurethane foam is used for insulation.
