[0002] With the rapid development of the construction industry and the continuous innovation of construction methods, building shapes are constantly changing. However, most buildings adopt open truss systems. After the steel structure or cast-in-place beam construction is completed, the scaffolding needs to be dismantled because the weight of the beam rests entirely on the scaffolding, making dismantling the scaffolding a difficult task. In order to ensure the stability of the bottom of the scaffolding, supports are usually installed at the bottom of the scaffolding. However, the existing support bases are not convenient for height adjustment, which is inconvenient during use. Summary of the Invention

Detailed Implementation

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Example: Figure 1 , Figure 2 , Figure 3 As shown, this utility model discloses a prefabricated building support for construction engineering, including a base 1 and a lifting seat 2. The base 1 is provided with a pair of vertically upward positioning cylinders 3. The bottom of the lifting seat 2 is provided with a telescopic rod 4 that extends and retracts along the positioning cylinders 3, and the positioning cylinders 3 are provided with an anti-detachment positioning mechanism to fix the telescopic rod 4. The upper surface of the lifting seat 2 is provided with a support 14 for supporting the bottom of the supported bracket.

[0023] The anti-detachment positioning mechanism includes a vertically arranged straight rack 6 mounted on the side wall of the telescopic rod 4, a limiting tube 7 on the side wall of the positioning cylinder 3, a sliding block 8 that moves along the limiting tube 7, and teeth 9 that mesh with the straight rack 6 on the sliding block 8. A threaded cylinder 10 is installed at the outer end of the limiting tube 7, and a manual screw 11 is installed inside the threaded cylinder 10. The inner end of the manual screw 11 is rotatably connected to the sliding block 8 via a rotating component. A jack installation area is provided between the pair of positioning cylinders 3 on the base 1, which allows for... Place the jack between the supports and limit its position using the positioning groove 13. When providing support, the jack is used to lift the lifting seat 2. When the seat is raised to the required height, the support 14 supports the bottom of the support frame. The telescopic rod 4 is then positioned by an anti-detachment positioning mechanism. This mechanism uses the teeth 9 on the sliding block 8 to engage with the straight rack 6, which provides excellent positioning and prevents loosening or slippage, thus ensuring good stability. Once the position is fixed, simply extend and remove the jack.

[0024] The base 1 has a jack installation area between a pair of positioning cylinders 3. The base 1 is provided with a limiting block 12 for positioning the bottom of the jack, and the limiting block 12 is provided with a positioning groove 13 that fits with the bottom of the jack, which facilitates the limiting of the jack.

[0025] The support 14 has a limiting groove 15 that matches the bottom of the supported bracket, and the support 14 is installed on the lifting seat 2 via a disassembly mechanism. The disassembly mechanism includes multiple screw holes 16 on the lifting seat 2. Positioning blocks 23 are provided on both sides of the support 14. Each positioning block 23 has a through hole 17 corresponding to one of the screw holes 16. Positioning bolts 18 are installed between the through holes 17 and the screw holes 16, allowing the positioning blocks to be fixed using the positioning bolts 18. This facilitates disassembly and allows for the replacement of different support blocks when supporting different brackets, thus providing high versatility.

[0026] The lifting seat 2 has a raised docking block 20 on its surface, and the support 14 has an embedding groove at its bottom for the docking block 20 to be embedded, which makes it convenient to install the support.

[0027] The telescopic rod 4 is provided with a groove 5 for storing the rack, thus facilitating the movement of the telescopic rod along the positioning cylinder. The bottom of the lifting seat 2 is provided with reinforcing ribs.

[0028] During operation, this type of prefabricated building support for construction projects has a jack installation area between a pair of positioning cylinders 3 on the base 1. The jack can be placed between them and then limited by the positioning groove 13. When providing support, the jack is used to lift the lifting seat 2. When it is lifted to the required support height, the support 14 supports the bottom of the supported bracket. The telescopic rod 4 is positioned by an anti-detachment positioning mechanism, in which the upper teeth 9 of the sliding block 8 engage with the straight rack 6, which provides a good positioning effect and prevents loosening and slippage, thus having good stability. After it is fixed, the jack can be telescopically removed.
