[0028] An embodiment of the present application provides an adjustable steel independent support device for a basement, referring to Figures 1 to 5 , including: an independently supported bottom section, an independently supported adjustable top section, wherein:

[0029] The independently supported bottom section includes a bottom section body 1, a steel column base 2, and reinforcing ribs 3. The steel column base 2 is a sheet steel structure, and the upper end surface of the steel column base 2 is connected to the bottom end of the bottom section body 1. The two side edges of the reinforcing ribs 3 are respectively connected to the upper end surface of the steel column base 2 and the side surface of the bottom section body 1.

[0030] Specifically, the reinforcing rib 3 may be a triangular steel sheet, and the plane where the reinforcing rib 3 is located is perpendicular to the plane where the steel column foot 2 is located.

[0031] The independently supported adjustable top section includes a top section body 4, a steel pipe 5, and an adjustable flat plate top support. The side surfaces of several of the steel pipes 5 are connected to the side surfaces of the top end of the top section body 4. The length direction of the steel pipes 5 is parallel to the length direction of the top section body 4. The threaded pipe 7 of the adjustable flat plate top support is arranged in the steel pipe 5.

[0032] Specifically, the height of the independently supported adjustable top section can be 1m to 1.5m, with an adjustment space of 0.5m. It can be installed normally in basements with different clear heights, and has strong applicability.

[0033] In some embodiments, the adjustable flat plate support includes a top plate 6, a threaded tube 7, and an adjusting nut 8. The bottom end surface of the top plate 6 is connected to one end of the threaded tube 7, and the other end of the threaded tube 7 is arranged in the steel pipe 5. The adjusting nut 8 is sleeved on the threaded tube 7 and is located above the steel pipe 5.

[0034] Specifically, the adjustable flat plate top support is used to adjust the support height to achieve an adjustable effect to meet the different requirements of basement floor heights. The steel column is placed in the corresponding position, and the adjustable top section on the top of the steel column is adjusted until it is adjusted to the appropriate position to ensure that the top of the steel column can be pressed tightly against the floor slab.

[0035] In some embodiments, a partition is also connected to the top of the top section body 4, and the partition is located above the steel pipe 5. An opening is opened on the partition at a position opposite to the cavity of the steel pipe 5. The threaded tube 7 extends through the opening into the cavity of the steel pipe 5, and the adjusting nut 8 is located above the partition.

[0036] Specifically, by setting the partition, the adjusting nut 8 can abut against the upper end surface of the partition, thereby bearing the force applied from the top plate 6 to the bottom. The shape and diameter of the partition opening and the steel pipe 5 cavity should be able to accommodate the threaded pipe 7 and allow the adjusting nut 8 to abut against the upper end surface of the partition.

[0037] In some embodiments, the side surface of the steel pipe 5 is connected to the side surface of the top end of the top section body 4 by double-sided welding.

[0038] Specifically, the independently supported adjustable top section can be double-sided welded by a steel column with a diameter of 194 mm and a wall thickness of 6 mm and a steel pipe 5 with a diameter of 48 mm and a wall thickness of 3 mm, and the welding length is preferably not less than 300 mm.

[0039] In some embodiments, it also includes: an independently supported standard section, including a standard section body 9, and flanges arranged at the upper and lower ends of the standard section body 9, and the independently supported standard section is installed between the independently supported bottom section and the independently supported adjustable top section.

[0040] Specifically, the height of the independent support standard section can be set to 1m to 2m, which can be used to adjust the height of the adjustable steel independent support device of the entire basement.

[0041] In some embodiments, the upper end of the bottom section body 1, the lower end of the top section body 4 and the upper and lower ends of the standard section body 9 are connected with flanges, which can be connected by welding, and the flanges can be fixed with 6 M20 bolts.

[0042] In some embodiments, the bottom section body 1 , the top section body 4 , and the quasi-section body are all hollow steel columns; there are four steel pipes 5 , which are evenly arranged on the side surface of the top end of the top section body 4 .

[0043] In some embodiments, the principles and processes of using the basement adjustable steel independent support device for construction include:

[0044] 1. Through in-depth design of construction drawings in advance, determine the size and quantity of materials, and weld and produce them in the factory to ensure the quality of components.

[0045] 2. According to the construction elevator foundation drawing, determine the location of the foundation, measure the distance in advance before construction, make steel columns of corresponding lengths, and make fine adjustments by adding steel pads. According to the axis, release the center position of the construction elevator foundation on the top plate 6, and mark the corresponding position in the basement to ensure that the adjustable steel independent support is exactly in the center of the elevator foundation.

[0046] 3. Independent steel column support The foundation reinforcement of the construction elevator is to install an independent steel column support under the floor where the construction elevator needs to be installed. The whole set of adjustable steel independent support consists of independent support bottom section, independent support standard section, independent support short section, independent support adjustable top section, M20 bolts and other components. Different components are matched on site according to the net height of the basement, assembled with M20 bolts, and supported to the top of the basement through the flat top of the adjustable top section 6.

[0047] 4. The upper construction elevator load is transferred to the structural bottom plate or foundation through steel pads and independent steel columns, thereby ensuring structural safety and normal use of the construction elevator, achieving the effect of effectively supporting and transferring the load.

[0048] In summary, compared with the prior art, the basement adjustable steel independent support device provided by the present application has the following beneficial effects:

[0049] 1. Less material input: Compared with the traditional construction method, the adjustable steel independent support of the elevator basement is supported by a circular steel column, which greatly optimizes the material input, reduces the floor space and facilitates construction.

[0050] 2. Reduce costs: The adjustable steel independent support of the construction elevator basement does not need to set up complicated full-height frames, which reduces the cost of the project and improves the construction quality and project image.

[0051] 3. Improve the erection speed: The construction elevator basement can be independently supported by adjustable steel sections, which has fast installation speed and simple operation. Compared with the traditional full-floor support frame process, it can increase the erection speed by more than 10 times.

[0052] 4. Strong adjustability: The construction elevator basement is independently supported by adjustable steel sections and has an adjustable top section. It can be flexibly adjusted according to the actual clear height of the basement, and can well cope with the changes in the clear height of the basement after turnover and actual needs.

[0053] 5. Multiple turnover times: The construction elevator basement can be independently supported by adjustable steel sections, and the floor slab reinforcement under the construction elevator foundation is standardized. The reinforced independent steel columns can be rotated and used multiple times.
