Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, specifically a fixing device for fixing the I-beam of a cable-stayed cantilever frame. Background Technology
[0002] I-beams are commonly used in construction projects, especially when building cantilever structures. Due to their excellent strength and stability, I-beams can withstand large loads, making them ideal for cantilever applications.
[0003] When fixing the cantilevered scaffold I-beams with diagonal bracing, it is usually necessary to use rope fixing equipment. Expansion bolts are usually used to fix them inside the building or to bury them inside the building. However, the load-bearing capacity is low, which can easily lead to the cantilevered scaffold I-beams falling off and causing safety accidents. At the same time, dismantling is inconvenient, making it difficult to reuse the equipment. Furthermore, after dismantling, cracks appear in the wall that are not easy to repair, resulting in a decrease in the overall aesthetics. Utility Model Content
[0004] The purpose of this utility model is to provide a fixing device for fixing the I-beams of a cantilevered scaffold. By setting threaded pipes, collars, anchor rings, sealing caps, wing nuts, and PVC sleeves, it solves the problem that when fixing the I-beams of a cantilevered scaffold with inclined supports, it is usually necessary to use rope fixing equipment. Expansion bolts are usually fixed inside the building or buried inside the building, but the load-bearing capacity is low, which can easily lead to the I-beams of the cantilevered scaffold falling off and causing safety accidents. At the same time, it is inconvenient to dismantle, making it difficult to reuse the equipment. Moreover, after dismantling, cracks appear in the wall that are not easy to repair, resulting in a reduction in the overall aesthetics.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a fixing device for fixing the I-beam of a fixed inclined cantilever frame, comprising a threaded tube, a limiting block fixedly connected to the top end of the surface of the threaded tube, a collar sleeved on the surface of the threaded tube, a rotating seat fixedly connected to the surface of the collar, an anchor ring rotatably connected inside the rotating seat, and a limiting ring threadedly connected to the surface of the threaded tube below the collar.
[0006] Preferably, the bottom end of the threaded tube is threaded with a wing nut, and the bottom end of the wing nut is threaded with a sealing cap.
[0007] Preferably, a threaded seat is fixedly connected to the upper surface of the wing nut, and a PVC sleeve is threadedly connected to the surface of the threaded seat.
[0008] Preferably, the PVC sleeve is fitted onto the surface of the threaded pipe, and a knob is fixedly connected to the surface of the limiting ring.
[0009] Preferably, a protective cap is inserted into the top end of the threaded tube, and a pull ring is fixedly connected to the upper surface of the protective cap.
[0010] Preferably, the lower surface of the sealing cap is provided with a knob groove, and the collar is rotatably connected to the surface of the threaded pipe through a limiting block.
[0011] This utility model provides a fixing device for fixing the I-beam of a cable-stayed cantilever scaffold, which has the following features:
[0012] Beneficial effects:
[0013] When in use, this equipment is poured into the building concrete. It is then used with anchor rings, shackles, high-strength anti-slip hooks, and tie rods or ropes to diagonally fix the I-beam. This provides better diagonal support for the I-beam and prevents it from falling due to equipment loosening. The threaded pipe can be removed for easy reuse, and the wing nut can be reused. After the operation is completed, the protruding PVC sleeve can be cut off and the surface can be smoothed with concrete. This prevents cracks on the building surface from being difficult to completely fill and smooth, which could affect the building's strength and aesthetics. Attached Figure Description

[0021] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a fixing device for fixing the I-beam of a cantilevered inclined frame, including a threaded pipe 1, a limiting block 2 fixedly connected to the top end of the surface of the threaded pipe 1, a collar 3 sleeved on the surface of the threaded pipe 1, a rotating seat 4 fixedly connected to the surface of the collar 3, an anchor ring 5 rotatably connected inside the rotating seat 4, and a limiting ring 6 threadedly connected to the surface of the threaded pipe 1 below the collar 3. During installation and use, the collar 3 is inserted into the threaded pipe 1, and then the limiting ring 6 is installed on the threaded pipe 1 to limit the collar 3 and keep the anchor ring 5 at the end position, which facilitates connection with other components and also facilitates installation and disassembly.
[0024] The bottom end of the threaded pipe 1 is threaded with a wing nut 7, and the bottom end of the wing nut 7 is threaded with a sealing cap 8.
[0025] By casting the wing nut 7 into the concrete, it can be kept in the concrete and not easily fall out, thereby improving the load-bearing capacity and stability of the equipment after installation. The sealing cover 8 prevents concrete from seeping into the wing nut 7.
[0026] The upper surface of the wing nut 7 is fixedly connected to a threaded seat 9, and the surface of the threaded seat 9 is threadedly connected to a PVC sleeve 10. During pouring, the PVC sleeve 10 keeps the inside of the equipment clean and prevents concrete from seeping in.
[0027] The PVC sleeve 10 is fitted onto the surface of the threaded pipe 1, and the surface of the limiting ring 6 is fixedly connected to the knob 11.
[0028] A protective cover 12 is inserted into the top of the threaded tube 1. A pull ring 13 is fixedly connected to the upper surface of the protective cover 12. The protective cover 12 can reduce the entry of external impurities into the equipment during use, and prevent the threaded tube 1 from being difficult to remove or damaged and unusable.
[0029] The lower surface of the sealing cap 8 is provided with a knob groove 14, and the collar 3 is rotatably connected to the surface of the threaded pipe 1 through the limiting block 2 and the limiting ring 6.
[0030] Specifically, the fixing device for the I-beam of this fixed inclined cantilever frame works as follows: When in use, the device is cast into the building concrete. The I-beam is fixed by inclined tensioning through the anchor ring 5, shackles, high-strength anti-slip hooks, and other equipment, along with tie rods or ropes. This provides better inclined tensioning support for the I-beam and prevents it from falling due to loosening of the equipment. At the same time, the threaded pipe 1 can be removed for easy reuse, and the wing nut 7 can also be reused. After the work is completed, the protruding PVC sleeve 10 can be cut off and the surface can be smoothed with concrete. This avoids the situation where cracks on the building surface are difficult to completely fill and smooth, which would affect the strength and aesthetics of the building.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
