[0001] The utility model relates to the technical field of capacitors, in particular to an anchor bolt with increased tensile strength. Background Art
[0002] Anchor bolts are usually used to provide stable connection and support for mechanical equipment, large structures, etc. to prevent them from displacement, tilting or shaking during operation, ensuring the normal operation and safety of the equipment. In some working environments with vibration and impact, anchor bolts can provide a reliable connection, firmly connecting the equipment to the foundation, enhancing the integrity and seismic resistance of the entire structure, and reducing loosening and damage caused by vibration and impact.
[0003] Common anchor bolts include L-type anchor bolts, U-type anchor bolts and anchor-type anchor bolts. Anchor bolts are often used in industrial plants, power facilities and bridge construction to stably connect the bottom of various equipment with the fixed base to ensure that the connected equipment is stable enough as a whole. Anchor bolts play a vital role in various projects and equipment installations, ensuring the normal operation and safety of equipment and structures.
[0004] Before using the existing anchor bolts, one end of the anchor bolt is deeply buried in the concrete, leaving the threaded end outside. After the concrete is completely solidified, the threaded end can be fixedly connected to the equipment to be fixed. However, during actual use, the anchor bolts may be deformed and loosened due to insufficient tensile strength, causing the connected equipment to deviate in angle and collapse, which has a significant impact on personnel safety. Utility Model Content
[0005] In order to remedy the above deficiencies, the utility model provides anchor bolts with increased tensile strength, aiming to improve the problem in the prior art that the anchor bolts may be deformed and loosened due to insufficient tensile strength during actual use, resulting in angular displacement and collapse of the connected equipment, causing significant impact on personnel safety.
[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an anchor bolt with increased tensile strength, comprising a bolt column and a steel clamp, the bottom end of the bolt column is fixedly connected with a plurality of L-shaped fixing feet, the top ends of the plurality of L-shaped fixing feet are fixedly connected with conical blocks, the middle parts of the top ends of the plurality of conical blocks are fixedly connected with steel cables, a plurality of circular holes are opened at the upper end of the outer wall of the bolt column, the top end of the conical block is fixedly connected with a plastic tube, the top end of the plastic tube is connected with the circular hole, the top end of the steel cable passes through the plastic tube, the top ends of the plurality of steel cables are fixedly connected to the bottom of the steel clamp, the top of the steel clamp is fixedly connected with a fixing buckle, the top of the fixing buckle is fixedly connected with a circular buckle, and a replacement mechanism is provided at the top of the bolt column.
[0007] As a further description of the above technical solution:
[0008] The replacement mechanism includes a first steel pipe and a double-headed screw. The top of the bolt column is communicated with the first steel pipe. A groove is provided on the inner wall of the first steel pipe. A second steel pipe is slidably connected to the inside of the first steel pipe. A slide rail is fixedly connected to the outer wall of the second steel pipe. A screw thread is provided on the inner wall of the second steel pipe. The screw thread is threadedly connected to the lower end of the double-headed screw. A positioning plate is fixedly connected to the middle of the double-headed screw.
[0009] As a further description of the above technical solution:
[0010] A spring gasket is fixedly connected to the top of the positioning plate. Two fixing nuts are threadedly connected to the upper middle part of the double-headed screw.
[0011] As a further description of the above technical solution:
[0012] A protective shell is provided at the top end of the positioning plate. A chute is provided on the inner wall of the protective shell. The chute is slidably connected to the outer wall of the fixing nut.
[0013] As a further description of the above technical solution:
[0014] A rubber gasket is fixedly connected to the top end of the first steel pipe. The inner wall of the rubber gasket fits with the top end of the first steel pipe.
[0015] As a further description of the above technical solution:
[0016] The slide rail is slidably connected to the groove.
[0017] As a further description of the above technical solution:
[0018] The radius of the second steel pipe is smaller than the radius of the first steel pipe.
[0019] The utility model has the following beneficial effects:
[0020] 1. In the utility model, when the anchor bolts are buried in advance, the three L-shaped fixing feet at the bottom can play a stabilizing role, and the positioning plate arranged above can ensure the horizontal angle of the bolts when filling the concrete. When the bolts are connected to the equipment to be fixed, the circular buckle at the bottom of the double-headed screw will tighten the fixing buckle. At this time, the three steel cables connected below the fixing buckle will pass through the holes opened on the bolt column body and be connected to the conical blocks fixed at the top ends of the L-shaped fixing feet below, generating an upward pulling force. When the pulling force is too large, the L-shaped fixing feet connected to the ends of the steel cables will be deformed, making the grasping force of the fixing feet on the concrete stronger, thereby enhancing the overall tensile strength of the anchor bolts.
[0021] 2. In the present utility model, when the tensile force of the double-headed screw connected above the bolt is too large, the steel pipe II threadedly connected to the lower end of the screw will slightly slide up and down with the steel pipe I, but the steel pipe II will not rotate left and right inside the steel pipe I. When the upper double-headed screw needs to be replaced, only by turning the positioning block in the middle of the double-headed screw can the entire double-headed screw be taken out for replacement, which greatly saves the cost of replacing the entire anchor bolt and also saves more time spent on replacing the anchor bolt.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0030] Refer to Figure 1 、 Figure 2 and Figure 3, an embodiment provided by the present utility model: an anchor bolt for increasing tensile strength, including a bolt column 1 and a steel clip 8. A plurality of L-shaped fixing feet 5 are fixedly connected to the bottom end of the bolt column 1. The top ends of the plurality of L-shaped fixing feet 5 are fixedly connected with conical blocks 6. The middle parts of the top ends of the plurality of conical blocks 6 are fixedly connected with steel cables 4. A plurality of circular holes 7 are opened in the upper part of the outer wall of the bolt column 1. The top end of the conical block 6 is fixedly connected with a plastic pipe 3. The top end of the plastic pipe 3 is communicated with the circular hole 7. The top ends of the steel cables 4 penetrate through the plastic pipe 3. The top ends of the plurality of steel cables 4 are fixedly connected to the bottom of the steel clip 8. The top of the steel clip 8 is fixedly connected with a fixing buckle 9. The top of the fixing buckle 9 is fixedly connected with a circular buckle 10. A replacement mechanism 2 is arranged at the top of the bolt column 1;
[0031] Specifically, the plastic pipe 3 outside the steel cable 4 can prevent the steel cable 4 from being fixed by the concrete when pouring the concrete, so as to lose the stretching effect. When the bolt is connected to the equipment to be fixed, the fixing buckle 9 at the bottom of the double-headed screw 206 will tighten the circular buckle 10. At this time, the three steel cables 4 connected below the steel clip 8 will pass through the circular holes 7 opened on the bolt column 1 and be connected to the conical blocks 6 fixed at the top ends of the lower L-shaped fixing feet 5, so as to generate an upward pulling force. When the pulling force is too large, the L-shaped fixing feet 5 connected to the ends of the steel cables 4 will be deformed due to the huge pulling force, so that the grasping force of the fixing feet on the concrete becomes stronger, and the stability and tensile resistance are higher.
[0032] Referring to Figure 1 , Figure 2 and Figure 3 , the replacement mechanism 2 includes a steel pipe one 201 and a double-headed screw 206. The top of the bolt column 1 is communicated with the steel pipe one 201. A groove 202 is opened in the inner wall of the steel pipe one 201. A steel pipe two 203 is slidably connected inside the steel pipe one 201. A slide rail 204 is fixedly connected to the outer wall of the steel pipe two 203. A screw thread 205 is opened in the inner wall of the steel pipe two 203. The screw thread 205 is threadedly connected to the lower end of the double-headed screw 206. A positioning plate 207 is fixedly connected to the middle of the double-headed screw 206. A spring gasket 14 is fixedly connected to the top of the positioning plate 207. Two fixing nuts 15 are threadedly connected to the upper middle part of the double-headed screw 206.
[0033] Specifically, the groove 202 formed on the inner wall of the steel pipe 1 201 fits with the slide rail 204 fixed to the outer wall of the steel pipe 2 203, enabling the steel pipe 2 203 to slide on the inner wall of the steel pipe 1 201. The spring washer 14 placed on the positioning plate 207 can make the two fixing nuts 15 tighter when fixing the equipment. The screw thread 205 formed inside the steel pipe 2 203 fits with the thread at the lower end of the double-headed screw 206, enabling a tight threaded connection. When the upper double-headed screw 206 needs to be replaced, simply turn the positioning plate 207 in the middle of the double-headed screw 206 left and right, and the whole can be taken out. When a new double-headed screw 206 needs to be installed, repeat the above steps for installation, greatly saving the time wasted in replacing the anchor bolts in the traditional way.
[0034] Refer to Figure 1 、 Figure 2 and Figure 3 As shown in, a protective shell 12 is provided at the top of the positioning plate 207. A chute 11 is formed on the inner wall of the protective shell 12, and the chute 11 is slidably connected to the outer wall of the fixing nut 15. The top of the steel pipe 1 201 is fixedly connected with a rubber gasket 13, and the inner wall of the rubber gasket 13 fits with the top of the steel pipe 1 201. The slide rail 204 and the groove 202 are slidably connected, and the radius of the steel pipe 2 203 is smaller than that of the steel pipe 1 201;
[0035] Specifically, the chute 11 formed on the inner wall of the protective shell 12 fits with the outer wall of the fixing nut 15, thus preventing the fixing nut 15 from being exposed outside and extending its service life. When the double-headed screw 206 is threadedly connected to the screw thread 205 formed on the inner wall of the steel pipe 2 203, the rubber gasket 13 fixedly connected to the top of the steel pipe 1 201 makes the inside of the steel pipe 2 203 in a sealed state, preventing water from entering and causing rust under the double-headed screw 206.
[0036] Working principle: When a huge upward pulling force is generated on the steel cable 4, the L-shaped fixed foot 5 will bend inward, thus generating a greater grasping force on the concrete. The plastic pipe 3 covering the outside of the steel cable 4 can prevent the steel cable 4 from being covered by concrete during concrete pouring, resulting in the steel cable 4 stopping working. The tops of the three steel cables 4 are fixedly connected to the steel clip 8, the top of the steel clip 8 is fixedly connected to the fixing buckle 9, the top of the fixing buckle 9 is fixedly connected to the circular buckle 10, and the circular buckle 10 is fixed to the bottom of the steel pipe 2 203. When an upward pulling force is generated on the steel pipe 2 203, it will drive the circular buckle 10, the fixing buckle 9 and the steel clip 8 below, causing the steel cable 4 to work;
[0037] The groove 202 formed on the inner side of the steel pipe 1-201 is in close fit with the slide rail 204 fixed to the outer wall of the steel pipe 2-203, enabling the steel pipe 2-203 to slide up and down inside the steel pipe 1-201. The screw thread 205 formed inside the steel pipe 2-203 is fitted with the screw at the lower part of the double-headed screw 206, enabling the two to be threadedly connected. The rubber gasket 13 fixedly connected to the top of the steel pipe 1-201 can make the double-headed screw 206 be hermetically connected to the steel pipe 1-201, preventing moisture from entering and causing the screw to rust. When replacing the double-headed screw 206 above, just rotate the positioning plate 207 left and right, and the double-headed screw 206 can be disengaged from the inner wall of the steel pipe 2-203, so that it is no longer necessary to replace all the anchor bolts when replacing them.
[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
