Description

Technical Field

[0001] This utility model relates to the field of iron tower technology, specifically to a method for reinforcing concrete bases for iron towers with rebar anchoring. Background Technology

[0002] A steel tower is a tall structure primarily constructed of steel. It typically employs a truss or frame structure, made by welding and bolting steel components, combining strength with relatively light weight to achieve considerable height. Steel towers are usually installed on concrete foundations, as these foundations distribute the tower's load, prevent uneven ground settlement, enhance overall stability, protect the foundation components from external corrosion, and extend the tower's lifespan. When a tower has been in use for a long time and the concrete foundation shows signs of aging or cracking, or when the tower needs to be modified or upgraded to increase its load-bearing capacity, rebar is used to strengthen the connection between the foundation and the tower, improving the overall structural stability.

[0003] The current method for rebar anchoring typically involves drilling holes in the concrete base, adding high-strength anchoring adhesive into the holes, inserting the reinforcement material, and then connecting the reinforcement material and the base after the adhesive has cured. However, over time, the anchoring adhesive ages, becoming brittle and cracking, which reduces the bonding strength and consequently the connection strength between the reinforcement material and the base. This leads to decreased stability of the anchoring and makes it impossible to guarantee effective fixation of the anchoring over a long period. To address this, we propose a rebar anchoring method for reinforcing concrete bases of iron towers. Utility Model Content

[0004] The purpose of this utility model is to provide a method for reinforcing concrete bases of iron towers with rebar anchoring, in order to solve the problem mentioned in the background art that existing rebar anchoring relies solely on anchoring adhesive for fixation. Over time, the anchoring adhesive will age, and the aged anchoring adhesive will become brittle and crack, reducing the bonding strength. Consequently, the connection strength between the reinforcement material and the base will decrease, leading to a decline in the stability of the anchoring and making it impossible to guarantee the effective fixation of the anchoring for a long time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete base reinforced with rebar for iron towers, comprising a concrete base and a rebar anchoring cylinder. The top of the concrete base is provided with a rebar anchoring groove, and the rebar anchoring cylinder is inserted into the inner cavity of the rebar anchoring groove. A rebar column is fixedly connected to the bottom middle of the inner cavity wall of the rebar anchoring cylinder. The inner cavity of the rebar anchoring cylinder is provided with a vertical plate, and the vertical plate is evenly distributed in a ring. A fixing block is fixedly connected to the outer wall of the vertical plate, and the fixing blocks are evenly distributed from top to bottom. A pressing block is provided on the outer wall of the rebar column, and a limiting block is fixedly connected to the inner wall of the vertical plate.

[0006] As a further description of the above technical solution:

[0007] The pressing block is slidably connected to the outer wall of the reinforcing column, the top end of the reinforcing column extends to the outer side of the concrete base, the limiting block contacts the outer wall of the pressing block, the outer wall of the anchoring cylinder has a connecting opening, and the connecting opening is evenly distributed in a ring from top to bottom, the outer wall of the fixing block extends through the connecting opening to the inner cavity of the anchoring groove, the outer wall of the fixing block contacts the inner wall of the anchoring groove, and the outer wall of the fixing block has teeth.

[0008] As a further description of the above technical solution:

[0009] Pressing columns are fixedly connected to the top left and right sides of the pressing block. The top of the pressing column extends to the outside of the anchoring cylinder, and the pressing column is slidably connected to the anchoring cylinder. A fixing nut is screwed to the outer wall of the anchoring column, and the bottom of the fixing nut contacts the top of the two pressing columns.

[0010] As a further description of the above technical solution:

[0011] An installation rod is slidably connected to the lower inner side of the vertical plate. The two ends of the installation rod are fixedly connected to the rebar cylinder and the rebar column, respectively. Flow ports are opened on the left and right sides of the bottom of the inner cavity wall of the rebar cylinder.

[0012] As a further description of the above technical solution:

[0013] The outer side wall of the fixing nut is fitted with a limiting sleeve, and the top front and rear sides of the anchoring cylinder are provided with fixing screw holes. The outer side wall of the limiting sleeve is fixedly connected with a fixing plate on the front and rear sides, and the fixing plate is fixedly connected to the fixing screw holes by bolts.

[0014] As a further description of the above technical solution:

[0015] A protective cover is screwed to the outer wall of the reinforcing bar, and the fixing nut is located inside the protective cover. A reinforcing ring is fixedly connected to the bottom of the protective cover, and the reinforcing ring is inserted into the inner cavity of the reinforcing bar groove.

[0016] As a further description of the above technical solution:

[0017] A fluororubber sealing ring is fixedly connected to the bottom of the protective cover and outside the reinforcing ring, and the bottom of the fluororubber sealing ring is in contact with the top of the concrete base.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This iron tower uses rebar anchoring to reinforce the concrete base. A fixing block, in conjunction with a vertical plate and a limiting block, secures the fixing block. The limiting block, in conjunction with a pressing block, pressing column, and fixing nut, limits and fixes the fixing block, ensuring tight contact between the fixing block and the inner wall of the anchoring groove. This fixes the anchoring cylinder and, through its own toothed texture, increases friction with the anchoring groove, improving the anchoring cylinder's pull-out resistance and ensuring the stability of the anchoring column during use. This strengthens the connection between the anchoring and the concrete base, making the connection more stable and reliable, thus guaranteeing the stability of the anchoring during use.

[0020] 2. The steel tower uses rebar reinforcement to strengthen the concrete base. A limiting sleeve, along with a fixing plate and fixing screw holes, limits the fixing nut to prevent loosening during use, thus ensuring connection stability. A protective cover, along with a fluororubber sealing ring, protects the fixing nut from sun and rain corrosion, while also protecting the rebar adhesive inside the rebar groove, delaying its aging, maintaining its performance stability, and extending the service life of the rebar. The protective cover, in conjunction with a reinforcing ring, further limits the rebar cylinder, ensuring stability during use. This reinforces and protects the connection, thereby further improving stability during operation. Attached Figure Description

Figure 1-8 This includes a concrete base 100 and a rebar cylinder 200;

[0034] Please refer to it again. Figure 1-6The top of the concrete base 100 is provided with a rebar groove 110 for installing a rebar cylinder 200. The rebar cylinder 200 is inserted into the inner cavity of the rebar groove 110. A reinforcing bar column 210 is fixedly connected to the middle of the bottom of the inner cavity wall of the rebar cylinder 200. The reinforcing bar column 210 is used to connect with the iron tower to enhance its load-bearing capacity. The inner cavity of the rebar cylinder 200 is provided with a vertical plate 211 for installing fixing blocks 212. The vertical plates 211 are evenly distributed in a ring. The outer wall of the vertical plates 211 is fixedly connected with fixing blocks 212 for fixing the rebar cylinder 200. The fixing blocks 212 are evenly distributed from top to bottom. The outer wall of the reinforcing bar column 210 is provided with a pressing block 213 for cooperating with the limiting block 214 to... The vertical plate 211 is fixed in a limiting position. A limiting block 214 is fixedly connected to the inner side wall of the vertical plate 211. The limiting block 214 is used to limit the vertical plate 211. The pressing block 213 is slidably connected to the outer side wall of the reinforcing column 210. The top of the reinforcing column 210 extends to the outer side of the concrete base 100. The limiting block 214 contacts the outer side wall of the pressing block 213. The outer side wall of the rebar cylinder 200 has a connecting opening 220. The connecting opening 220 is used to facilitate the extension of the fixing block 212 to the outside of the rebar cylinder 200 and to limit the fixing block 212. The connecting opening 220 is evenly distributed in a ring from top to bottom. The outer side wall of the fixing block 212 extends through the connecting opening 220 to the inner cavity of the rebar groove 110. The outer side wall of the fixing block 212 and the rebar groove 110 are connected. The inner wall of the 10 is in contact, and the outer wall of the fixing block 212 is provided with teeth. The teeth increase the engagement between the fixing block 212 and the anchoring groove 110, thereby improving the fixing effect. The top left and right sides of the pressing block 213 are fixedly connected to the pressing column 230. The pressing column 230 is used to facilitate the operation of the pressing block 213. The top of the pressing column 230 extends to the outer side of the anchoring cylinder 200, and the pressing column 230 is slidably connected to the anchoring cylinder 200. The outer wall of the anchoring column 210 is screwed with a fixing nut 231. The fixing nut 231 is used to fix and limit the pressing block 213 through the pressing column 230. The bottom of the fixing nut 231 contacts the top of the two pressing columns 230. The lower inner side of the vertical plate 211 is slidably connected to the mounting rod 240. The mounting rod 240 is used to install the vertical plate 211. Both ends of the mounting rod 240 are fixedly connected to the anchoring cylinder 200 and the anchoring column 210, respectively. The bottom left and right sides of the inner wall of the anchoring cylinder 200 have flow ports 241 to facilitate the flow of anchoring adhesive, thus allowing the anchoring cylinder 200 and the anchoring groove 110 to form an integrated lifting and fixing effect after drying. In use, the anchoring cylinder 200 is placed in the anchoring groove 110, and the fixing nut 231 is rotated. The fixing nut 231 moves downward along the anchoring column 210. When the fixing nut 231 contacts the two pressing columns 230, it simultaneously presses down on the two pressing columns 230. The pressing columns 230 drive the pressing block 213 to move downward. When the pressing block 213 moves downward, it squeezes the outer limiting block 214, causing it to move outward.The limiting block 214 causes the vertical plate 211 to move outward on the mounting rod 240. The movement of the vertical plate 211 causes the fixing block 212 to extend from the connecting port 220 and contact the rebar groove 110. Continuous rotation of the fixing nut 231 ensures that the fixing block 212 and the rebar groove 110 are in tight contact. The fixing block 212 engages with the inner wall of the rebar groove 110 through its surface teeth, thus completing the installation of the rebar column 210.

[0035] In summary, this method can enhance the connection between the rebar and the concrete base, making the connection more stable and reliable, thereby ensuring the stability of the rebar during use.

[0036] Please refer to it again. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8 A limiting sleeve 250 is fitted onto the outer wall of the fixing nut 231. The limiting sleeve 250 is used to limit the fixing nut 231. Fixing screw holes 251 are provided on the front and rear sides of the top of the rebar cylinder 200. The fixing screw holes 251 are used to install the fixing plate 252 and to facilitate the pouring of rebar adhesive. The fixing plate 252 is fixedly connected to the front and rear sides of the outer wall of the limiting sleeve 250. The fixing plate 252 is used to fix the fixing plate 252 in conjunction with the fixing screw holes 251. The fixing plate 252 is fixedly connected to the fixing screw holes 251 by bolts. A protective cover 260 is screwed onto the outer wall of the rebar column 210. The protective cover 260 is used to protect the connection point. The fixing nut 231 is located inside the protective cover 260. A reinforcing ring 261 is fixedly connected to the bottom of the protective cover 260. The reinforcing ring 261 is used to provide auxiliary limiting for the rebar cylinder 200, further ensuring stability during use. 261 is inserted into the inner cavity of the rebar groove 110. The bottom of the protective cover 260 and the outside of the reinforcing ring 261 are fixedly connected to a fluororubber sealing ring 270. The fluororubber sealing ring 270 is used to cooperate with the protective cover 260 to improve the sealing of the connection and reduce the impact of sun and rain on the connection and internal structure, thereby ensuring the service life. The bottom of the fluororubber sealing ring 270 contacts the top of the concrete base 100. The limiting sleeve 250 is put on the fixing nut 231. Then, the bolt is passed through the fixing plate 252 and connected to the fixing screw hole 251 to fix the limiting sleeve 250. The limiting sleeve 250 limits the fixing nut 231. Then, the protective cover 260 is rotated and moved downward along the rebar column 210. The protective cover 260 drives the reinforcing ring 261 to be inserted into the rebar groove 110. At the same time, the fluororubber sealing ring 270 contacts the concrete base 100 to seal the connection.

[0037] In summary, this method can further strengthen the connection between the rebar and the concrete base, thereby further improving the stability during use.

[0038] In practical use, those skilled in the art place the rebar cylinder 200 in the rebar groove 110, rotate the fixing nut 231, and the fixing nut 231 moves downward along the rebar column 210. When the fixing nut 231 contacts the two pressing columns 230, it simultaneously presses down on the two pressing columns 230. The pressing columns 230 drive the pressing block 213 to move downward. When the pressing block 213 moves downward, it squeezes the outer limiting block 214 outward, causing it to move. The limiting block 214 then drives the vertical plate 211 to move outward on the mounting rod 240. The movement of the vertical plate 211 causes the fixing block 212 to extend out of the connecting port 220 and contact the rebar groove 110. Continuously rotating the fixing nut 231 ensures that the fixing block 212 is in tight contact with the rebar groove 110. The fixing block 212 engages with the inner wall of the rebar groove 110 through the toothed surface, thus completing the installation of the rebar column 210. Then, it is installed through the fixing screw hole 25. 1. Add anchoring adhesive to the inside of the anchoring cylinder 200. The anchoring adhesive flows into the anchoring groove 110 through the flow port 241 at the bottom of the anchoring cylinder 200. After drying, the anchoring cylinder 200 and the anchoring groove 110 form an integral lifting and fixing effect. After completion, put the limiting sleeve 250 on the fixing nut 231. Then, pass the bolt through the fixing plate 252 and connect it to the fixing screw hole 251 to fix the limiting sleeve 250. The limiting sleeve 250 limits the fixing nut 231. Then, rotate the protective cover 260 and move it downward along the anchoring column 210. The protective cover 260 drives the reinforcing ring 261 to be inserted into the anchoring groove 110. The reinforcing ring 261 works with the protective cover 260 to assist in limiting the anchoring cylinder 200. At the same time, the fluororubber sealing ring 270 contacts the concrete base 100 to seal the connection. Together with the protective cover 260, it reduces the exposure of the internal structure to sun and rain, thereby improving the service life.
