Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of anti - floating anchor rods, and more specifically, to an anti - floating anchor rod for building construction. Background Technique
[0002] With the continuous acceleration of the country's urbanization construction, a large number of high - rise buildings have been constructed. During the construction of high - rise buildings, anti - floating anchor rods are required. When in use, first measure and set the holes, then use a drilling rig to drill the holes, clean the drilled holes, align the bottom end of the anchor rod with the holes, put it into the holes, and perform grouting.
[0003] Most of the anti - floating anchor rods on the market now work through the friction between the surface of the anchor rod and the surrounding concrete slurry. Therefore, there are problems such as relatively small friction with the concrete, being not easy to be anchored after concrete pouring, and insufficient tensile and shear resistance.
[0004] Therefore, we make improvements on this and propose an anti - floating anchor rod for building construction. Content of the Utility Model
[0005] The purpose of the utility model is: The existing greening construction protection device has problems such as relatively small friction with the concrete, being not easy to be anchored after concrete pouring, and insufficient tensile and shear resistance.
[0006] In order to achieve the above - mentioned invention purpose, the utility model provides the following technical solutions:
[0007] An anti - floating anchor rod for building construction to improve the above problems.
[0008] Specifically, this application is as follows: It includes an anchor rod and a positioning block. A rotating rod is rotatably connected inside the positioning block. A rotating block is fixedly installed at one end of the rotating rod. A concrete baffle is rotatably connected to the surface of the rotating rod. A shear - resistance component is threadedly connected to the surface of the rotating rod. An expansion component is installed on the surface of the shear - resistance component. The shear - resistance component includes a fixed cylinder and a sliding plate. A sliding groove is opened on the inner surface of the fixed cylinder. The sliding plate slides in the sliding groove. A pushing cone is fixedly installed at one end of the sliding plate. The pushing cone is threadedly connected to the rotating rod. The expansion component includes a fixed frame and a second spring. The fixed frame and the second spring are fixedly connected to the surface of the fixed column. A rotating shaft is installed at one end of the fixed frame. A fixed cone plate is rotatably connected to the surface of the rotating shaft. A pushing plate is fixedly installed at one end of the second spring.
[0009] The thread on the surface of the rotating rod has the same length as the length for the pushing cone to move up and down. Through the threaded connection between the rotating rod and the pushing cone, the rotation of the rotating rod drives the pushing cone to descend along the sliding groove through the sliding plate, squeezing the fixed cylinder to make it extend, and then making the expansion component extend. When the expansion component extends out of the fixed cylinder, the pushing fixed cone plate installed at one end of the second spring rotates around the rotating shaft, causing it to open, increasing the contact area with the concrete to increase the friction force and shear resistance. When the fixed frame is inside the fixed cylinder, the second spring is in a compressed state.
[0010] As a preferred embodiment of the anti-floating anchor rod for building construction provided by the present utility model, a fixed cylinder is slidably installed inside the fixed cylinder, and a first spring is installed between the fixed cylinder and the fixed cylinder.
[0011] As a preferred embodiment of the anti-floating anchor rod for building construction provided by the present utility model, a rotating baffle is rotated at the inner end of the concrete baffle, and the rotating baffle is installed on the outer surface of the rotating rod.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: The thread on the surface of the rotating rod has the same length as the length for the pushing cone to move up and down. Through the threaded connection between the rotating rod and the pushing cone, the rotation of the rotating rod drives the pushing cone to descend along the sliding groove through the sliding plate, squeezing the fixed cylinder to make it extend, and then making the expansion component extend. When the expansion component extends out of the fixed cylinder, the pushing plate installed at one end of the second spring pushes the fixed cone plate to rotate around the rotating shaft, causing it to open, increasing the contact area with the concrete to increase the friction force and shear resistance. When the fixed frame is inside the fixed cylinder, the second spring is in a compressed state. Description of the Drawings

[0026] As described in the background art, in the existing technology, there are problems such as small friction with concrete, difficult anchoring after concrete pouring, and insufficient tensile and shear resistance.

[0033] Embodiment 1
[0034] Please refer to Figures 1-6, a building construction anti-floating anchor rod, including an anchor rod 1, a positioning block 3. A rotating rod 2 is rotatably connected inside the positioning block 3. One end of the rotating rod 2 is fixedly installed with a rotating block 5. The surface of the rotating rod 2 is rotatably connected with a concrete baffle 6. The surface of the rotating rod 2 is threadedly connected with a shear-resistant component 4. An expansion component 8 is installed on the surface of the shear-resistant component 4. The shear-resistant component 4 includes a fixed cylinder 41 and a sliding plate 44. A sliding groove 43 is opened on the inner surface of the fixed cylinder 41. The sliding plate 44 slides in the sliding groove 43. One end of the sliding plate 44 is fixedly installed with a pushing cone 42. The pushing cone 42 is threadedly connected with the rotating rod 2. A fixed column 45 is slidably installed inside the fixed cylinder 41. A first spring 46 is installed between the fixed column 45 and the fixed cylinder 41. A rotating baffle 7 is rotated at the inner end of the concrete baffle 6. The rotating baffle 7 is installed on the outer surface of the rotating rod 2.
[0035] During the implementation process, first place this device in the anchor hole. Then, the rotation of the rotating block 5 drives the rotating rod 2 to rotate inside the concrete baffle 6 through the rotating baffle 7. At this time, the rotating rod 2 is also rotatably arranged inside the positioning block 3. The anchor rod 1 is fixedly installed inside the positioning block 3 and the concrete baffle 6 respectively. The length of the thread on the surface of the rotating rod 2 is the same as the up and down movement length of the pushing cone 42. Through the threaded connection between the rotating rod 2 and the pushing cone 42, the rotation of the rotating rod 2 drives the pushing cone 42 to descend along the sliding groove 43 through the sliding plate 44, squeezing the fixed column 45 to make it extend, and the fixed column 45 squeezes the first spring 46 installed inside the fixed cylinder 41.
[0036] Example 2
[0037] The expansion component 8 includes a fixed frame 81, a second spring 82. The fixed frame 81 and the second spring 82 are fixedly connected to the surface of the fixed column 45. One end of the fixed frame 81 is installed with a rotating shaft 83. A fixed cone plate 84 is rotatably connected to the surface of the rotating shaft 83. One end of the second spring 82 is fixedly installed with a pushing plate 85.
[0038] During the implementation process, when the fixed cone plate 84 extends out of the inside of the fixed cylinder 41, the pushing plate 85 installed at one end of the second spring 82 pushes the fixed cone plate 84 to rotate around the rotating shaft 83, making it open, increasing the contact area with the concrete to increase the friction. When the fixed cone plate 84 is inside the fixed cylinder 41, since the upward rotation and opening angle of the fixed cone plate 84 are restricted by the fixed cylinder 41, the second spring 82 cannot push the fixed cone plate 84 through the pushing plate 85.
[0039] The above embodiments are only used to illustrate the present invention rather than limit the technical solutions described by the present invention. Although the present specification has described the present invention in detail with reference to the above respective embodiments, the present invention is not limited to the above specific implementation manners. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and their improvements that do not depart from the spirit and scope of the invention are covered by the scope of the claims of the present invention.
