Technical Field

[0001] This utility model relates to the technical field of cantilever slab support frames, and in particular to a support frame for cantilever slabs in prefabricated buildings. Background Technology

[0002] Cantilever slabs, also known as cantilever beams, are a common structural component in buildings, playing a vital supporting and load-bearing role. To improve the stability of cantilever slabs during construction, support devices are often installed to enhance their stability. Chinese utility model patent, authorization announcement number "CN220889647U", discloses a support frame for prefabricated cantilever slabs, including a base. Two bases are provided, each with casters at its four corners. Support columns are located at the top of the bases, with electric actuators inside the bottom of the support columns, penetrating the bases and having fixed plates at their bottoms. The fixed plates have wheel grooves at their four corners. T-shaped columns are slidably connected inside the support columns, and lifting devices are installed within the support columns. A buffer device is located at the top of the T-shaped columns. A crossbeam is located between the two support columns, with one end fixedly connected to the support column. A sliding rod is sleeved inside the crossbeam, and multiple screw holes are provided on both sides of the crossbeam. A bolt is threaded into one end of the sliding rod, connecting to the screw holes.

[0003] The above technical solution can not only automatically adjust the height, making it safer, but also adjust the width. However, the height support range is limited. The cantilever slabs of buildings are often set at high positions. If a support frame with a limited support range is used, it is easy to encounter the problem of not being able to provide support. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a support frame for the cantilever slab of prefabricated building, which can solve the problem of limited height support range. The cantilever slab of the building is often set at a high position, and if a support frame with limited support range is used, it is easy to encounter the problem of not being able to provide support.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a support frame for a prefabricated building cantilever slab, comprising a connecting component, an extension component, and a telescopic component;

[0006] The expansion component includes a support column, a slot, a clip, and a threaded hole. The clip is welded to the bottom of the support column, the threaded hole is opened on the clip, and the slot is opened at the top of the support column.

[0007] The telescopic assembly includes a square telescopic column, a square sleeve, and a base. The square sleeve is welded onto the base, and the square telescopic column slides along the inside of the square sleeve.

[0028] Please see Figure 1-6 This utility model provides a technical solution: a support frame for a prefabricated building cantilever slab, including a connecting component, an extension component, and a telescopic component;

[0029] The expansion assembly includes a support post 1, a slot 9, a clip 11, and a threaded hole 12. The clip 11 is welded to the bottom of the support post 1, the threaded hole 12 is opened on the clip 11, and the slot 9 is opened at the top of the support post 1.

[0030] The telescopic assembly includes a square telescopic column 2, a square sleeve 3, and a base 4. The square sleeve 3 is welded to the base 4, and the square telescopic column 2 slides along the inside of the square sleeve 3.

[0031] The connecting assembly includes a second threaded hole 14, a positioning post 15, a third threaded hole 16, and a spring 17. The positioning post 15 slides inside the third threaded hole 16. One end of the spring 17 is welded to the inside of the third threaded hole 16, and the other end of the spring 17 is welded to the positioning post 15. There are two connecting assemblies, which are respectively set on the support post 1 and the square telescopic post 2.

[0032] The motor 6 is installed inside the base 4 by screws, and the output shaft of the motor 6 is fitted with a motor gear 5 by a key pin.

[0033] The base 4 has a threaded column 7 that rotates through it. A gear 8 is fixedly sleeved on the surface of the threaded column 7 and meshes with the motor gear 5.

[0034] The upper end of the threaded column 7 is threadedly connected to a threaded sleeve 10, and the square telescopic column 2 is fixedly sleeved on the outside of the threaded sleeve 10.

[0035] The clip 11 is inserted into the corresponding slot 9 of the square telescopic column 2, and two threaded holes 16 are respectively opened on the support column 1 and the square telescopic column 2.

[0036] The internal thread of threaded hole 12 is connected to screw 13, which is connected to the surface thread of corresponding threaded hole 14, and screw 13 is connected to the internal thread of corresponding threaded hole 16.

[0037] It should be noted that: spring 17 is initially in a compressed state, and positioning pin 15 is initially positioned inside the corresponding threaded hole 16.

[0038] When it is necessary to support the cantilever beams of a building;

[0039] First, select an appropriate number of support columns 1 according to the distance from the building's cantilever beam, and assemble multiple support columns 1. External force drives the support columns 1 to move. The movement of the support columns 1 causes the locking piece 11 to move into the corresponding slot 9 of another support column 1. The movement of the locking piece 11 causes the slot 9 to move until it coincides with the position of the corresponding positioning column 15. Then, the spring 17 resets, causing the positioning column 15 to move into the threaded hole 12. Subsequently, an external tool drives the screw 13 to move. The screw 13 is installed into the threaded hole 14, then into the threaded hole 12, causing the positioning column 15 to move. The movement of the positioning column 15 compresses the spring 17, and the screw 13 is installed into the threaded hole 16.

[0040] Next, the assembled support columns 1 are installed on the square telescopic column 2. By driving the lowest support column 1 to move, the lowest support column 1 moves to the position corresponding to the positioning column 15 of the square telescopic column 2. The positioning column 15 is driven into the interior of the clamp 11 by the reset of the spring 17. Then, the screw 13 is installed to bring the positioning column 15 back into the interior of the threaded hole 16.

[0041] Finally, the motor 6 is started. The start of the motor 6 drives the motor gear 5 to rotate. The rotation of the motor gear 5 drives the gear 8 to rotate. The rotation of the gear 8 drives the threaded column 7 to rotate. The rotation of the threaded column 7 drives the threaded sleeve 10 to move. The movement of the threaded sleeve 10 drives the square telescopic column 2 to move upward. The movement of the square telescopic column 2 drives the uppermost support column 1 to move upward until it abuts against the building's cantilever beam slab.

[0042] By setting up extension components and telescopic components, the extension components can be selected in appropriate numbers according to the height of different building cantilever slabs to ensure that no matter how high the cantilever slab is, the support device can support the building cantilever slab in its highest state according to the number of extension components assembled. This avoids the predicament that the building cantilever slab is too high and ordinary support devices cannot extend to the lower end of the building cantilever slab to support it, thus expanding the practicality of the support device.

[0043] By installing the extension component on top of the telescopic component, it is easier to install the extension component on top of the telescopic component. This avoids having to run to the top of the extension component to complete the final installation, thus reducing the overall installation difficulty.

[0044] Working principle:

[0045] When it is necessary to support the cantilever beams of a building;

[0046] First, select an appropriate number of support columns 1 according to the distance from the building's cantilever beam, and assemble multiple support columns 1. External force drives the support columns 1 to move. The movement of the support columns 1 causes the locking piece 11 to move into the corresponding slot 9 of another support column 1. The movement of the locking piece 11 causes the slot 9 to move until it coincides with the position of the corresponding positioning column 15. Then, the spring 17 resets, causing the positioning column 15 to move into the threaded hole 12. Subsequently, an external tool drives the screw 13 to move. The screw 13 is installed into the threaded hole 14, then into the threaded hole 12, causing the positioning column 15 to move. The movement of the positioning column 15 compresses the spring 17, and the screw 13 is installed into the threaded hole 16.

[0047] Next, the assembled support columns 1 are installed on the square telescopic column 2. By driving the lowest support column 1 to move, the lowest support column 1 moves to the position corresponding to the positioning column 15 of the square telescopic column 2. The positioning column 15 is driven into the interior of the clamp 11 by the reset of the spring 17. Then, the screw 13 is installed to bring the positioning column 15 back into the interior of the threaded hole 16.

[0048] Finally, the motor 6 is started. The start of the motor 6 drives the motor gear 5 to rotate. The rotation of the motor gear 5 drives the gear 8 to rotate. The rotation of the gear 8 drives the threaded column 7 to rotate. The rotation of the threaded column 7 drives the threaded sleeve 10 to move. The movement of the threaded sleeve 10 drives the square telescopic column 2 to move upward. The movement of the square telescopic column 2 drives the uppermost support column 1 to move upward until it abuts against the building's cantilever beam slab.

[0049] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
