Description

Technical Field

[0001] The present application relates to the technical field of embedded bolts, and in particular to a type of embedded bolt. Background Art

[0002] Embedded bolts are widely used and important connecting components. Traditionally made of an L-shaped rod with a threaded end, embedded bolts rely primarily on their shape and surface friction when connecting to concrete.

[0003] However, problems arise in scenarios where high structural connection strength is required. The bonding force they generate is limited and often fails to meet requirements. For example, in structures subject to high external forces, such as high-rise buildings and coastal steel colored plate structures, these bolts are prone to loosening. This loosening not only weakens the local connection strength but can also cause internal stress changes due to uneven force distribution, leading to cracks in the surrounding concrete, further reducing overall structural stability and potentially causing serious safety accidents and significant loss of life and property. Utility Model Content

[0004] In order to solve the problem that traditional L-shaped embedded bolts rely on shape and surface friction, have limited bonding force, are easy to loosen, and affect structural stability, the present application provides an embedded bolt.

[0005] The embedded bolts provided in this application adopt the following technical solution:

[0006] A pre-embedded bolt includes an L-shaped anchor rod, which consists of a long arm and a short arm. The end of the long arm is provided with a thread for connecting to an external component. An anchoring reinforcement structure is provided on the end of the long arm close to the short arm, and the anchoring reinforcement structure includes a convex pattern provided on the long arm.

[0007] Preferably, the convex pattern is composed of a plurality of anti-slip protrusions, and the anti-slip protrusions can be selected from annular ribs, splines, bosses, etc., which are used to increase the mechanical bite force between the bolt and the concrete.

[0008] Preferably, the convex pattern adopts a thread design.

[0009] Preferably, a plurality of anchors are provided on the convex pattern, and the anchors include a threaded sleeve threadedly provided on the convex pattern, and the threaded sleeve is provided with a plurality of anchor claws distributed along the circumferential direction.

[0010] Preferably, the threaded sleeve is further provided with a plurality of anti-slip grooves.

[0011] In summary, this application has the following beneficial technical effects:

[0012] By using L-shaped anchor rods, threads, convex patterns and anchor pieces in combination, the anchor reinforcement structure can be used to increase the bite force between the L-shaped anchor rod and the concrete. The L-shaped anchor rod can also be connected to the anchor piece. During the pouring process, the threaded sleeve and the anchor claw play an anchoring role, effectively preventing the L-shaped anchor rod from moving in the horizontal and vertical directions, enhancing the subsequent anchoring effect, and providing a reliable foundation for subsequent structural connections. Compared with the existing technology, it has good fixing effect and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following is combined with Figure 1 —3 Provide further details of this application.

[0018] Example 1

[0019] The embodiment of the present application discloses a pre-embedded bolt. Figure 1 A pre-buried bolt includes an L-shaped anchor rod 1 consisting of a long arm 101 and a short arm 102. A thread 2 is provided on the top of the long arm 101 for connecting a nut to achieve the installation of external components.

[0020] Reference Figure 1 An anchoring reinforcement structure is installed on the end of the long arm 101 close to the short arm 102. The anchoring reinforcement structure includes a convex pattern 3 installed on the long arm 101. The convex pattern 3 is composed of several anti-slip protrusions. The anti-slip protrusions can be customized according to needs, such as annular ribs, bosses, splines, threads, etc., which are used to increase the mechanical bite force between the L-shaped anchor rod 1 and the concrete.

[0021] Among them, if annular ribs are used, the annular ribs should be distributed along the axial direction, with a width between 2-5 mm, a depth between 1-3 mm, and a distance between adjacent annular ribs between 3-8 cm.

[0022] If bosses are used, they should be staggered in the circumferential and axial directions, with a width of 2-5 mm, a depth of 1-3 mm, and a distance between adjacent bosses of 1-3 cm.

[0023] The embedded bolts in this embodiment work as follows: During use, a bonding agent is applied directly to the surface of the L-shaped anchor rod 1 and the ridge 3, and then the L-shaped anchor rod 1 is placed into the concrete to enhance the bonding strength between the L-shaped anchor rod 1 and the concrete. Once the concrete solidifies, the embedded bolts can be stably embedded in the concrete, providing a reliable foundation for subsequent structural connections.

[0024] Example thread 2

[0025] The embodiment of the present application discloses a pre-embedded bolt. Figure 2 A pre-buried bolt includes an L-shaped anchor rod 1 consisting of a long arm 101 and a short arm 102. A thread 2 is provided on the top of the long arm 101 for connecting a nut to achieve the installation of external components.

[0026] Reference Figure 3 An anchor reinforcement structure is installed on the end of the long arm 101 near the short arm 102. The anchor reinforcement structure includes a ridge 3 installed on the long arm 101, and the ridge 3 adopts a threaded design. Several anchors 4 are installed on the ridge 3. The anchors 4 include a threaded sleeve 401 threadedly installed on the ridge 3, and the threaded sleeve 401 is equipped with several anchor claws 402 distributed along the circumference. The L-shaped anchor rod 1 is connected to the anchor 4. During the pouring process, the threaded sleeve 401 and the anchor claws 402 play an anchoring role, effectively preventing the L-shaped anchor rod 1 from moving horizontally and vertically, enhancing the subsequent anchoring effect, and providing a reliable foundation for subsequent structural connections. Several anti-slip grooves 5 are also installed on the threaded sleeve 401 to further enhance the mechanical bite force between the threaded sleeve 401 and the concrete.

[0027] The implementation principle of the embedded bolts in the embodiment of the present application is as follows:

[0028] During use, threaded sleeve 401 is placed over the surface of ridge 3 and screwed to the bottom. An adhesive is applied to the surfaces of L-shaped anchor rod 1, ridge 3, and anchor 4. The L-shaped anchor rod 1 is then placed into the concrete to enhance the bond between the L-shaped anchor rod 1 and the concrete. During the pouring process, threaded sleeve 401 and anchor claw 402 provide an anchoring force, effectively preventing horizontal and vertical displacement of the L-shaped anchor rod 1. Once the concrete solidifies, the embedded bolt can be stably embedded in the concrete, providing a reliable foundation for subsequent structural connections.
