Description

Technical Field

[0001] This utility model relates to the field of engineering installation components technology, specifically to a concrete pre-embedded anchor bolt. Background Technology

[0002] Concrete embedded anchors are fasteners that are pre-embedded in the concrete foundation (or structure) according to design requirements before concrete pouring, and are used to subsequently fix equipment and structural components (such as steel structure column bases, heavy machinery bases, etc.). Through mechanical interlocking, bonding, or locking with the concrete, they withstand the tensile forces, shear forces, and vibrations during equipment operation, ensuring a long-term stable connection between the structure and the foundation.

[0003] In related technologies, pre-embedded bolts typically include a hammer head at the bottom of the anchor bolt, a smooth rod section in the middle of the anchor bolt, and a threaded section at the top of the anchor bolt. The threaded section is equipped with a hexagonal nut and a flat washer that are compatible with its threads. In order to fix the existing anchor bolts more firmly in the anchor hole, adhesive is filled into the concrete anchor hole before installation, so that the connection between the anchor bolt and the concrete is tighter after installation. However, special tools are required to fill the adhesive, which reduces the installation speed of the anchor bolt during installation, and excess adhesive will overflow from the top of the anchor hole, which will also cause adhesive waste. To solve the above problems, a concrete pre-embedded anchor bolt is proposed to solve the above problems. Utility Model Content

[0004] In view of this, the present invention provides a concrete pre-embedded anchor bolt. The present invention uses a hammer to break through the ring sleeve by hammering, thereby splitting the ring sleeve into arc-shaped pieces that are inverted and embedded in the concrete. At this time, the storage sleeve breaks, allowing the adhesive to fill the lower half of the anchor hole along the gap on the anchor bolt. At the same time, the storage cylinder breaks, allowing the adhesive inside to fill the anchor hole, thereby facilitating the installation of the anchor bolt and saving the installation time. The adhesive can also be collected through the groove on the flat washer, preventing the adhesive from overflowing and being wasted.

[0005] To solve the above-mentioned technical problems, this utility model provides a concrete pre-embedded anchor bolt, including an expansion hammer head at the lower part of the anchor bolt, an anchor sleeve on the surface of the expansion hammer head, a smooth rod section in the middle of the anchor bolt, a threaded section at the upper part of the anchor bolt, a nut on the threaded section, a storage sleeve on the inner wall of the anchor sleeve, the storage sleeve being filled with adhesive, a storage cylinder on the upper surface of the smooth rod section, the storage cylinder being filled with adhesive, and a flat washer at the lower part of the nut, with several grooves at the bottom of the flat washer for receiving adhesive.

[0006] The anchor sleeve includes a sleeve fitted onto the bottom of the smooth rod section. The sleeve is used to install the ring sleeve and the storage sleeve. The lower outer wall of the sleeve is provided with an engagement groove, which is used to improve the connection between the anchor sleeve and the concrete. The engagement groove is annular. The lower end of the sleeve is provided with a deformable and expandable ring sleeve, which is used to embed the anchor bolt in the concrete to prevent the anchor bolt from falling off.

[0007] The anchor sleeve also includes four irregular keyways arranged along its axial direction. The irregular keyways are used to strengthen the connection between the sleeve and the concrete, so that the anchor sleeve is more firmly fixed in the concrete. Each irregular keyway extends to the lower end of the ring sleeve, so that the ring sleeve forms a four-lobed arc plate, so that the ring sleeve can be replaced and extended to fit into the inner wall of the concrete.

[0008] Each arc-shaped piece is provided with a pair of positioning grooves. The positioning grooves are used to reinforce the connection between the arc-shaped piece and the concrete, thereby reinforcing the connection between the expansion hammer and the concrete. The positioning grooves are circular.

[0009] The lower surface of the nut is provided with a ring plate, which is used to install a spring washer, thereby connecting the spring washer to the nut. The ring plate is circular, and a spring washer is provided between the ring plate and the flat washer.

[0010] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. By hammering, the expanding hammer head breaks through the ring sleeve, causing the ring sleeve to split into arc-shaped pieces that are inverted and embedded in the concrete. At this time, the storage sleeve breaks, allowing the adhesive to fill the lower half of the anchor hole along the gap on the anchor bolt. At the same time, the storage cylinder breaks, allowing the adhesive inside to fill the anchor hole, thus facilitating the installation of the anchor bolt and saving installation time. The adhesive can also be collected through the groove on the flat washer, preventing adhesive overflow and waste.

[0011] 2. The irregular keyway is used to strengthen the connection between the sleeve and the concrete, so that the anchor sleeve is more firmly fixed in the concrete. Each irregular keyway extends to the lower end of the ring sleeve, so that the ring sleeve forms a four-lobed arc plate, so that the ring sleeve can be replaced and extended to fit into the inner wall of the concrete.

[0012] 3. The positioning groove is embedded in the surface of the arc-shaped piece. The positioning groove is used to reinforce the connection between the arc-shaped piece and the concrete, thereby strengthening the connection between the expansion hammer and the concrete, making the arc-shaped piece more firmly embedded in the concrete.
