Description

Technical Field

[0001] This utility model relates to a hanging nail, specifically a double-headed hanging nail, belonging to the technical field of double-headed hanging nail structures. Background Technology

[0002] Double-headed ceilings, also known as round-headed hanging nails, are a common component in prefabricated buildings. Many building components are manufactured and processed in workshops, including exterior wall panels, interior wall panels, composite slabs, balconies, air conditioning panels, stairs, precast beams, and precast columns. Prefabricated buildings mostly utilize precast concrete components to achieve rapid construction. These components are typically cast in reusable molds and pre-cured in a controlled environment before being transported to the construction site and hoisted to the designated location. For ease of hoisting, round-headed hanging nails are pre-embedded in the precast concrete components, based on their shape, size, and weight, serving as hoisting points. Using round-headed hanging nails in conjunction with lifting equipment simplifies the component production process, facilitates hoisting, minimizes worker operation time, and ensures the safety of precast concrete components during production and transportation.

[0003] A search revealed a precast component lifting round-headed nail structure disclosed in Chinese Patent Publication No. CN219860079U, which includes a precast template, a steel reinforcement support, corrugated rubber, a duckbill lifting device, and a cast-in-place wall. The inner wall of the precast template is slidably connected to a fixed column, and the outer wall of the fixed column is fixedly connected to a first fixed ring and a second fixed ring. The inner wall of the precast template has a first fixed groove for the first fixed ring to engage, and the inner wall of the corrugated rubber has a second fixed groove for the second fixed ring to engage. The inner wall of the corrugated rubber is slidably connected to a round-headed nail, one end of which is fixedly connected to the steel reinforcement support, and the other end of which is engaged with the duckbill lifting device.

[0004] While the aforementioned device fixes the corrugated rubber to the outer wall of the precast template using a fixing column, and concrete is poured into the reinforcing steel support through the grouting port, the precast template along with the corrugated rubber is removed after the concrete has solidified. At this point, a groove appears at the top of the poured wall, with one end of the round lifting nail located in the center of the groove. The poured wall can then be hoisted by engaging the duckbill lifting device with the round lifting nail. However, the pre-embedding of the round-headed lifting nail requires the cooperation of components such as corrugated rubber, fixing columns, and limiting plates. The assembly and installation of these components is too cumbersome, time-consuming, and labor-intensive, increasing the operating cost. Therefore, we provide a double-headed lifting nail to solve the above problems. Utility Model Content

[0005] To solve the above problems, this utility model provides a double-headed hanging nail, and the specific technical solution is as follows:

[0006] A double-ended hanging nail includes a nail rod, a semi-circular frame, a first threaded rod, and multiple second threaded rods. The nail rod has a first threaded hole and a fixing ring is fixedly connected to it. The fixing ring is fixedly connected to an elastic element. The semi-circular frame has a semi-circular cavity and a sealing gasket is fixedly connected to it. The first threaded rod has a first round head with a first cross groove. The first cross groove has multiple second threaded holes, and each of the multiple second threaded rods has a second cross groove.

[0007] Preferably, the nail rod is fixedly connected to a second round head, and the elastic element is fixedly connected to the semi-circular frame.

[0008] Preferably, the semi-circular frame is slidably connected to the nail rod, and the first threaded hole is threadedly connected to the first threaded rod.

[0009] Preferably, the second threaded hole is threadedly connected to the second threaded rod, and a prefabricated template is provided on the outside of the nail rod.

[0010] Preferably, the precast template has multiple pouring holes and installation holes.

[0011] Preferably, the sealing gasket is pressed against one side of the precast template, and the plurality of second threaded rods are pressed against one side of the precast template.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This double-headed hanging nail controls the first round head to pass through the mounting hole, causing the sealing gasket to press against one side of the precast template. Then, a Phillips screwdriver is inserted into the first Phillips groove, and rotating the Phillips screwdriver causes the first round head to rotate, moving the first round head upward. When the second threaded rod moves out of the mounting hole, the Phillips screwdriver is inserted into the second Phillips groove and rotated, causing the second threaded rod to move outward from the inside of the second threaded hole. By rotating the first round head with the Phillips screwdriver, multiple second threaded rods press against one side of the precast template, thus achieving the purpose of convenient installation of this device.

[0014] 2. After the double-headed lifting nail is fixedly installed, while ensuring the device is fixed, by controlling the Phillips screwdriver to insert into the first Phillips groove and rotate it left and right, the first round head will rotate left and right, and at the same time, the first threaded rod will move up and down inside the first threaded hole, thereby moving the nail rod up and down. This allows adjustment of the length of the nail rod exposed inside the semi-circular cavity, making the device compatible with a wider range of lifting tools. After the device is fixed inside the concrete, by controlling the Phillips screwdriver to insert into the first Phillips groove and rotate it left and right, the first round head will rotate left and right, and at the same time, the first threaded rod will move up and down inside the first threaded hole, thereby moving the first round head up and down. This allows adjustment of the height of the first round head exposed in the semi-circular cavity, making the device adjustable for the height of the pre-embedded round head, and making it compatible with a wider range of lifting tools, thus achieving the wide applicability of this device.

The first cross groove 10 has multiple second threaded holes 11, and each of the multiple second threaded rods 12 has a second cross groove 11. 3. The nail rod 1 is fixedly connected to the second round head 14. The elastic element 3 is fixedly connected to the semi-circular frame 4. The semi-circular frame 4 is slidably connected to the nail rod 1. The first threaded hole 7 is threadedly connected to the first threaded rod 8. The second threaded hole 11 is threadedly connected to the second threaded rod 12. A precast template 15 is provided on the outside of the nail rod 1. The precast template 15 has multiple pouring holes 16 and installation holes 17. The sealing gasket 6 is pressed against one side of the precast template 15. Multiple second threaded rods 12 are pressed against one side of the precast template 15.

[0022] The elastic element 3 here is preferably made of spring material. When the second threaded rod 12 is not completely removed from the second threaded hole 11, it can support and press against the precast template 15. The sealing gasket 6 is made of rubber. By controlling the first round head 9 to pass through the mounting hole 17 and press the sealing gasket 6 against one side of the precast template 15, and then inserting a Phillips screwdriver into the first Phillips groove 10 and rotating the Phillips screwdriver to rotate the first round head 9, the first threaded rod 8 moves upward inside the first threaded hole 7, and the first round head 9 moves upward simultaneously. When the second threaded rod 12 moves out of the mounting hole 17, by controlling the Phillips screwdriver to rotate inside the second Phillips groove 13, the second threaded rod 12 moves outward from the inside of the second threaded hole 11. By rotating the first round head 9 with the Phillips screwdriver, multiple second threaded rods 12 press against one side of the precast template 15, achieving the purpose of convenient installation of this device and solving the problem of needing corrugated rubber, fixing posts, and limiting devices when pre-embedding round-headed hanging nails. The assembly and installation of components such as plates and other parts are too cumbersome, time-consuming, and labor-intensive, increasing operating costs. This device offers convenience. With the device fixed in place, by controlling the Phillips screwdriver inserted into the first Phillips groove 10 and rotating it left and right, the first round head 9 rotates left and right, simultaneously moving the first threaded rod 8 up and down inside the first threaded hole 7, thus moving the nail rod 1 up and down. This allows adjustment of the length of the nail rod 1 exposed inside the semi-circular cavity 5, making the device compatible with a wider range of lifting tools. After the device is fixed inside the concrete, by controlling the Phillips screwdriver inserted into the first Phillips groove 10 and rotating it left and right, the first round head 9 rotates left and right, simultaneously moving the first threaded rod 8 up and down inside the first threaded hole 7, and simultaneously moving the first round head 9 up and down. This allows adjustment of the exposed height of the first round head 9 inside the semi-circular cavity 5, making the device adjustable for the height of the pre-embedded round head, and further expanding its compatibility with a wider range of lifting tools, thus achieving versatility in its use.

[0023] In use, this utility model works as follows: When installing and fixing the device, the first round head 9 is controlled to pass through the mounting hole 17, and the sealing gasket 6 is pressed against one side of the precast template 15. Then, a Phillips screwdriver is inserted into the first Phillips groove 10, and rotating the Phillips screwdriver drives the first round head 9 to rotate, causing the first threaded rod 8 to move upward inside the first threaded hole 7. At the same time, the first round head 9 moves upward. When the second threaded rod 12 moves out of the mounting hole 17, the Phillips screwdriver is inserted into the second Phillips groove 13 and rotated, causing the second threaded rod 12 to move outward from the second threaded hole 11. The first round head 9 is rotated by the Phillips screwdriver, causing multiple second threaded rods 12 to press against one side of the precast template 15, thus achieving the purpose of convenient installation of this device. This ensures the device is fixed in place. By controlling the Phillips screwdriver to rotate left and right inside the first Phillips groove 10, the first round head 9 rotates left and right, simultaneously driving the first threaded rod 8 to move up and down inside the first threaded hole 7, thereby driving the nail rod 1 to move up and down. This allows adjustment of the length of the nail rod 1 exposed inside the semi-circular cavity 5, making the device compatible with a wider range of lifting tools. After the device is fixed inside the concrete, by controlling the Phillips screwdriver to rotate left and right inside the first Phillips groove 10, the first round head 9 rotates left and right, simultaneously driving the first threaded rod 8 to move up and down inside the first threaded hole 7, and simultaneously driving the first round head 9 to move up and down. This allows adjustment of the exposed height of the first round head 9 in the semi-circular cavity 5, making the device adjustable for the height of the pre-embedded round head, and enabling a wider range of compatible lifting tools, thus achieving the wide applicability of this device.
