[0018] The following is a further description of the present invention in conjunction with specific embodiments. It should be understood that the following embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.
[0019] Example 1
[0020] Figure 1 It is a structural schematic diagram of the utility model. Figure 2 This is a schematic diagram of the structure of embedded steel bars.
[0021] like Figure 1-2 As shown, a construction structure of an antifreeze street lamp comprises: a street lamp pole 100 and a cement pier 200, the cement pier 200 is arranged in a ground tunnel 300, the street lamp pole 100 is connected to the cement pier 200, the cement pier 200 comprises: a concrete shell 210, embedded steel bars 220, a fixing flange 230, a drainage hole 240, a cable channel 250 and an antifreeze layer 260, the embedded steel bars 220 are arranged in the ground tunnel 300, the concrete shell 210 is connected to the embedded steel bars 220, the fixing flange 230 is connected to the top of the embedded steel bars 220, the drainage hole 240 is arranged at the bottom of the concrete shell 210, the cable channel 250 is arranged in the center of the embedded steel bars 220, the cable channel 250 is connected to the cable 400 when in use, and the antifreeze layer 260 is arranged on the inner side of the concrete shell 210;
[0022] Among them, the embedded steel bar 220 includes: a steel bar body 221, a connecting plate 222, a first threaded structure 223, a second threaded structure 224, a third threaded structure 225, a bolt 226, an expansion anchor head 227 and an extension structure 228. The steel bar body 221 is connected to the fixing flange 230 through the connecting plate 222. The steel bar body 221 is provided with a first threaded structure 223, a second threaded structure 224, and a third threaded structure 225 from top to bottom. The bolt 226 and the expansion anchor head 227 are threadedly connected to the steel bar body 221. The top of the expansion anchor head 227 is a round head structure. The extension structure 228 is leaf-shaped. The extension structure 228 is connected to the expansion anchor head 227.
[0023] The antifreeze layer 260 includes: a sandwich structure 261 and a polyurethane foam material 262 . The sandwich structure 261 is fixedly connected to the inner side of the concrete shell 210 , and the polyurethane foam material 262 is arranged in the sandwich structure 261 .
[0024] The thickness values of the first thread structure 223 , the second thread structure 224 , and the third thread structure 225 are arranged from high to low.
[0025] The utility model has made two improvements in the traditional street lamp construction structure. On the one hand, an additional sandwich structure 261 is added, and a polyurethane foam material 262 is added to the sandwich structure 261. By using the polyurethane foam material as the filling of the middle layer, it can effectively insulate and prevent thermal bridges, thereby reducing heat loss. Similar technologies are often used in severe cold environments.
[0026] On the other hand, the innovation of the utility model is to improve the embedded steel bar 220 so that the street lamp can withstand strong cold winds. First, the threaded structure is added. The threaded structure can first improve the holding force. The threaded structure can increase the contact area between the anchor and the soil or rock, thereby improving the holding force and stability; secondly, the threaded structure can also apply prestress. The threaded structure is convenient for applying prestress during the installation process, which helps to determine the bearing capacity of the anchor in the soil in advance and ensure its performance in extreme environments. At the same time, we have adopted a multi-stage threaded structure, dividing the steel bar body 221 into a first threaded structure 223, a second threaded structure 224, and a third threaded structure 225, and the thickness values are arranged from high to low. Therefore, not only the threads are different, but also the thickness and diameter are different. In this way, a multi-level thread design of different thicknesses is adopted to adapt to soil layers of different depths, which can not only effectively improve the stability of the anchor under different soil conditions, but also has low modification costs. The expansion anchor head 227 can expand the anchor volume by rotating after the anchor is installed in place, further enhancing the fixing effect of the anchor in the soil. The principle is to expand its volume by rotating, thereby forming a larger anchor point inside the hole. When the expansion anchor head 227 is tightened, its round head part will push the surrounding materials, causing the anchor system to expand inside the hole, increasing the contact area with the hole wall, thereby providing a stronger anchoring force. To further enhance this effect, we have added an additional expansion structure 228, which is a blade-like structure to increase its anchoring force. The bolt 226 can move up and down along the thread of the steel bar, which allows the position of the steel bar to be adjusted during installation, ensuring the correct alignment of the expansion anchor head 227 with the structural member. At the same time, by applying a rotational force to the bolt during installation, prestressing can be generated in the steel bar, which helps to determine the bearing capacity of the anchor in the soil or rock in advance and ensure its performance in extreme environments.
[0027] The utility model not only adds an extra insulation layer, but also improves the structure of the pre-buried steel bars so that the street lamp can withstand strong winds in cold regions, thereby ensuring the safety and stability of the street lamp.
[0028] The specific implementation modes of the present invention are described above, but the present invention is not limited thereto. The present invention can also have various changes without departing from the purpose of the present invention.
