Description

Technical Field

[0001] This utility model belongs to the technical field of construction facilities for building engineering, and in particular relates to a support device for building engineering. Background Technology

[0002] In building construction, support devices are commonly used. These devices provide temporary support for structural components and are removed after construction is complete. For example, when installing overhead pipelines in a building, support devices are needed to provide auxiliary support for the pipelines and cable trays. After construction is finished, the support devices are removed or moved to the next construction location. Therefore, support devices have a significant impact on building construction (including construction efficiency and results).

[0003] Existing support devices are typically constructed using steel structures, resulting in a bulky and difficult-to-move configuration. Furthermore, support devices used in building construction require the ability to support structural components of varying heights, necessitating rapid height adjustment and further height adjustments as they approach the component's support surface, ultimately providing stable support. Current support devices lack sufficient flexibility and their adjustment characteristics fail to meet the demands of construction projects. Utility Model Content

[0023] To further understand the invention content, features and effects of this utility model, the following embodiments are provided in detail.

[0024] Please see Figure 1This utility model discloses a building engineering support device, comprising a movable base frame 1, a lifting platform 2 installed on top of the base frame 1, a lifter 3 installed between the base frame 1 and the lifting platform 2, a top support assembly 4 installed on the lifting platform 2, and a deformation control expander 5 installed inside the top support assembly 4. The base frame 1 serves as a carrier, supporting the lifting platform 2 and the top support assembly 4, and is moved on-site. The lifter 3 drives the lifting platform 2 to perform lifting and lowering movements to initially adjust the set support height, and the expander 5 drives the top support assembly 4 to undergo shape changes to further adjust the set support height.

[0025] Please see Figure 2 It can be seen that:

[0026] The basic frame 1 includes a support frame 1-2, a brake roller 1-1 is installed at the bottom of the support frame 1-2, two opposing top beams 1-3 are installed at the top of the support frame 1-2, and two parallel support beams 1-4 are installed on the two top beams 1-3.

[0027] Please see Figure 2 It can be seen that:

[0028] The lifting platform 2 includes a platform plate 2-2, with guide rods 2-1 installed at the four corners of the platform plate 2-2. Guide sleeves are installed at corresponding positions on the support frame 1-2, with each guide rod 2-1 located within its respective guide sleeve. The lifting device 3 is installed between the support beam 1-4 of the base frame 1 and the platform plate 2-2 of the lifting platform 2.

[0029] In this embodiment, the lifting device 3 is a scissor jack. The scissor jack has an operable rotating end. The end is driven by a tool to rotate in the forward or reverse direction, and the support height of the scissor jack changes. The scissor jack is an existing component that was purchased, and its structure and function will not be described in detail.

[0030] Please see Figure 3 and Figure 4 It can be seen that:

[0031] The top support assembly 4 includes a base 4-1 detachably connected to the lifting platform 2. The base 4-1 has two sets of left and right axle seats 4-3 and two bottom axles 4-5. It also includes two folding support arms 4-4 with a central axle 4-7 in the middle. The lower end of the folding support arm 4-4 is fixedly connected to the axle end of the bottom axle 4-5, and the upper end of the folding support arm 4-4 is hinged to a top axle 4-13. It also includes a top support plate 4-8 with two base plates 4-12 at the bottom, fixedly connected to the axle end of the top axle 4-13. Side protective frames 4-14 extending diagonally downwards are installed on the front and rear edges of the top support plate 4-8. The side protective frames 4-14 provide lateral protection and prevent foreign objects from entering the space below the top support plate 4-8.

[0032] The expansion device 5 is installed between the two central shafts 4-7 and drives the two central shafts 4-7 to change the distance between them. As shown in the figure, when the distance between the two central shafts 4-7 is shortened, the height of the top support assembly 4 increases and the top support plate 4-8 rises. Conversely, when the distance between the two central shafts 4-7 is increased, the height of the top support assembly 4 decreases and the top support plate 4-8 falls.

[0033] In this embodiment, the folding support arm 4-4 includes two upper support arms and two lower support arms. The lower end of the upper support arm is hinged to the upper end of the lower support arm on the same side via a central shaft 4-7. The lower end of the lower support arm is fixedly connected to the shaft end of the bottom shaft 4-5 on the same side. The upper ends of the two folding support arms 4-4 are hinged to the top shaft 4-13.

[0034] In this embodiment, a diagonal bracing beam 4-11 is also provided between the two upper arms of the folding support arm 4-4. The diagonal bracing beam 4-11 has shaft holes at both ends, with the middle shaft 4-7 passing through the bottom shaft hole and the top shaft 4-13 passing through the top shaft hole. The diagonal bracing beam 4-11 enhances the overall structural strength of the folding support arm 4-4. In this embodiment, the top support assembly 4 also includes an inverted A-shaped reinforcing frame 4-6. The bottom end of the reinforcing frame 4-6 is fixedly connected to the middle of the bottom shaft 4-5 on this side, and the top two sides of the reinforcing frame 4-6 are fixedly connected to the middle of the two lower arms of the folding support arm 4-4. The reinforcing frame 4-6 enhances the overall structural strength of the folding support arm 4-4.

[0035] In this embodiment, an upwardly extending connecting plate 4-9 is installed at the shaft end of one bottom shaft 4-5, and a downwardly extending connecting plate 4-9 is installed at the same side shaft end of the other bottom shaft 4-5. A connecting rod 4-10 is provided between the two connecting plates 4-9. The two folding support arms 4-4 are arranged in a mirror image manner. Therefore, when the shape of the top support assembly 4 is adjusted by the expansion device 5, the swing directions of the lower support arms of the two folding support arms 4-4 are synchronous and opposite. The two connecting plates 4-9 and the connecting rod 4-10 constitute a linkage assembly, which can further ensure the synchronicity of the movement of the two folding support arms 4-4.

[0036] In this embodiment, assembly holes 2-3 are provided at the four corners of the platform plate 2-2 of the lifting platform 2, and connecting columns 4-2 with external threads are provided at the bottom of the four corners of the base 4-1 of the top support assembly 4. Each connecting column 4-2 is located in the respective assembly hole 2-3 and is locked and fixed with a lock nut. In this way, the lifting platform 2 and the top support assembly 4 have a detachable connection structure.

[0037] In this embodiment, the expansion device 5 includes an adjusting sleeve located in the middle and telescopic rods located on both sides. Connecting sleeves are provided at the outer ends of the telescopic rods, and the two connecting sleeves are respectively fitted onto the two central shafts 4-7. The left side of the inner wall of the adjusting sleeve has a forward internal thread, and the right side has a reverse internal thread. The two telescopic rods have external threads with opposite directions of rotation, and the inner ends of both telescopic rods are located inside the adjusting sleeve. Thus, when the adjusting sleeve is rotated, the two telescopic rods move synchronously into or out of the adjusting sleeve. When the two telescopic rods move synchronously into the adjusting sleeve, the distance between the two central shafts 4-7 decreases, and the support height increases. Conversely, when the two telescopic rods move synchronously out of the adjusting sleeve, the distance between the two central shafts 4-7 increases, and the support height decreases.

[0038] How to use:

[0039] During construction, the support device is moved to the position below the support location, and each brake roller 1-1 is locked in place. The lifting device lifts the component to the installation position. Then, the lifting device 3 is operated to raise the height of the lifting platform 2, and the height of the top support assembly 4 is raised until the top support plate 4-8 of the top support assembly 4 moves a certain distance below the component and stops. Then, the expansion device 5 is operated to change the shape of the top support assembly 4, further raising the height of the top support plate 4-8 until the top support plate 4-8 contacts the bottom of the component above. Then, the lifting device 3 or the expansion device 5 is operated to make the top support plate 4-8 provide a stable supporting effect on the component above. Then, the component is installed and fixed. Then, the lifting device 3 and the expansion device 5 are operated in reverse to lower the height of the support device, and then it is moved to the next construction position.
