Description
Technical Field
[0001] The present application relates to an independent support system for a basement post-cast strip, and belongs to the field of post-cast strip support structures. Background Art
[0002] With the development of social economy, new technological practices have shown a diversified development trend. Large steel structures with beautiful, novel, unique and complex shapes have emerged. Buildings, processes and sub-projects using steel structures can be seen everywhere in people's vision. These steel structures have shown their unique charm and their construction technology has also made new breakthroughs. With their emergence, my country's large-scale steel structures have entered a new era of coexistence of opportunities and challenges. Therefore, it is necessary to further analyze and discuss the relevant technical points in the construction process, hoping to help promote the application of new and relatively immature construction technologies as soon as possible, thereby improving the technical level and scientific and technological content of construction companies and the entire industry.
[0003] As high-rise complexes continue to increase. In order to prevent harmful cracks that may occur in the individual cast-in-place reinforced concrete structures in high-rise complexes due to uneven shrinkage or settlement, multiple settlement post-casting strips are designed, and the settlement post-casting strips are too long to be closed. Traditional post-casting strips mostly use disc-type or ordinary steel pipe fastener scaffolding to return to the top, which occupies turnover materials for a long time and cannot form an efficient construction and transportation channel for the basement. The use of steel pipe materials exposed to a humid environment for a long time will not only cause the steel pipes to rust, the formwork and wood to rot, and affect the support effect, but also lack support for the concrete components when replacing the support, resulting in cracks in the process. The steel pipe support has poor force resistance and is easy to be damaged and disassembled. The rental cost is high and it is not easy to maintain in the later stage. Especially in the construction process of large basements, the cantilevered part of the post-casting strip has a large span and a relatively large deadweight, so a better solution is needed.

DETAILED DESCRIPTION
[0024] The present application is further described below in conjunction with specific embodiments and drawings.
[0025] refer to Figure 1 to Figure 4 As shown, an independent support system for a basement post-cast zone includes an I-beam main body 1, the specification of the I-beam main body 1 is 16#; the I-beam main body 1 includes a web 101 and a wing plate 102, wherein the number of the wing plates 102 is two and they are arranged in parallel and opposite to each other, and the web 101 is arranged between the two wing plates 102 and is respectively perpendicular to the wing plates 102 at the end.
[0026] A top plate 2 is provided at the top of the I-beam body 1, and an adjustable top support 3 is provided on the top plate 2. The top plate 2 is perpendicular to the I-beam body 1 and welded to the top of the I-beam body 1, providing a stable bottom surface structure for the adjustable top support 3. A foot support assembly 4 is provided at the bottom end of the I-beam body 1, and the foot support assembly 4 plays a role in stabilizing the I-beam body 1 on the bottom surface when it is in use.
[0027] The adjustable top support 3 includes a support seat 301, a support rod 302 and a support hand 303. The support seat 301 is welded and fixed on the top plate 2. The lower end of the support rod 302 is threadedly connected to the support seat 301. By rotating the height of the support rod 302 in the support seat 301, the entire adjustable top support 3 can be provided with an upper and lower adjustable range of 0 to 20 cm. The upper end of the support rod 302 is welded and connected to the support hand 303. The support hand 303 is an upward U-shaped structure, which increases the contact force area with the corresponding beam and improves the stability of the support.
[0028] The foot support assembly 4 includes an end reinforcement plate 401 with a specification of 160mm*150mm*10mm and a side reinforcement plate 404 with a specification of 150mm*150mm*10mm. The end reinforcement plate 401 is arranged between the ends on the same side of the wing plate 102. The outer side of the end reinforcement plate 401 is provided with an end support plate 402. The side reinforcement plate 404 is arranged on the outer side of the wing plate 102. The outer side of the side reinforcement plate 404 is provided with a side support plate 405. The support plate is a triangular steel plate with a size of 150mm*150mm*10mm, and its vertical edges are welded to the corresponding reinforcement plate. The clamping of the I-beam body 1 by the end reinforcement plate 401 and the side reinforcement plate 404 and the support of the end support plate 402 and the side support plate 405 can meet the requirements of the stable placement of the I-beam body 1 on the ground.
[0029] To meet different needs, the connection relationship between the end reinforcement plate 401, the side reinforcement plate 404 and the I-beam body 1 can be fixed or detachable;
[0030] For example, in order to improve the stability and processing convenience of the support system, the end reinforcement plate 401 is welded to the wing plate 102, and the side reinforcement plate 404 is welded to the wing plate 102. The foot support assembly 4 and the I-beam body 1 are welded to form a whole, which is more stable.
[0031] For example, in order to improve the storage convenience and disassembly of the foot support assembly 4, the end reinforcement plate 401 is fixed to the wing plate 102 by screws 403. After use, the foot support assembly 4 can be directly removed from the I-beam body 1 to reduce the storage space.
[0032] The side reinforcing plates 404 are connected by tensioning screws 406, which can fix the side reinforcing plates 404 on the outside of the wing plate 102, and can strengthen the clamping of the side reinforcing plates 404 on the I-beam body 1, thereby improving the stability of the foot support assembly 4. At the same time, the use of tensioning screws 406 also facilitates the disassembly and storage of the side reinforcing plates 404, thereby reducing the storage space on the ground when the support system is not in use.
[0033] The end reinforcement plate 401 is arranged parallel to the web 101 , the end support plate 402 is arranged parallel to the wing plate 102 , the side reinforcement plate 404 is arranged parallel to the wing plate 102 , and the side support plate 405 is arranged parallel to the web 101 , which serves as a stable fixing structure for the I-beam body 1 .
[0034] In addition, the foot support assembly 4 also includes a bottom support plate 407 with a specification of 160mm*150mm*10mm. The bottom support plate 407 is arranged between the bottoms on the same side of the wing plate 102 and welded to the bottom end of the wing plate 102, thereby improving the stability of the entire support system on the bottom surface.
[0035] The working process of the independent support system of the post-cast basement in this application is as follows:
[0036] 1) Check the stress on the I-beam, conduct rationality analysis and stress calculation on the I-beam support system, prepare a large number of 16# I-beams, 10mm thick steel plates, several senior welders and supporting welding equipment and common tools, and a large amount of data preparation is required in the early stage.
[0037] 2) Processing of I-beam support components: Process the I-beam body 1 and the steel plate according to the detailed drawings of the I-beam nodes, and complete the installation of the I-beam body 1 and the foot support assembly 4. For the welding part, the welds must be full and the node positions must be accurate; for the threaded connection, the drilling must be accurate.
[0038] 3) Laying out and checking the I-beam support: According to the I-beam support positioning drawing, use the ink fountain line to position and lay out the I-beam support, and control the position deviation within ±5mm.
[0039] 4) Treatment of the I-beam support foundation surface: Treat the foundation surface after the positioning line is laid, clean the concrete slurry and gravel, and ensure that the levelness of the contact surface between the I-beam and the concrete meets the requirements, and the surface flatness meets the requirements.
[0040] 5) Install I-beam supports.
[0041] Install the I-beam body 1 and the foot support assembly 4 on the processed base surface, place the upper top support on the corresponding beam, rotate the top support for reinforcement, fully weld a 160mm*150mm*10mm steel plate on the top of the I-beam, use an oversized adjustable top support 3 to weld it to the steel plate (top plate 2), and control the adjustable support condition range between 0 and 20cm. The I-beam supports the bottom of the post-cast belt beam at the starting position 300mm inward from the cantilever beams on both sides of the post-cast belt.
