Description

Technical Field

[0001] This utility model relates to the field of steel structure construction in civil engineering, specifically to a column base wrapping steel structure mold. Background Technology

[0002] With the rapid development of my country's economic construction, the application scope of steel structures in the field of industrial equipment is constantly expanding, the market's acceptance of steel structures is continuously improving, and the application volume is growing rapidly and continuously. Steel structures are structures composed of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses, and other components made of steel sections and plates, which are usually connected by welds, bolts, or rivets.

[0003] The structural system features lightweight construction, easy installation, short construction period, good seismic resistance, fast investment recovery, low environmental pollution, and strong spatial design flexibility, making it widely used in large factories, stadiums, and high-rise buildings. The steel column base encasing mold is a novel device creatively invented in the practical application of steel structure buildings. To prevent the steel column bases from being bumped or corroded by groundwater, thus affecting structural safety, concrete encasing of the steel column bases has become a crucial construction process.

[0004] The traditional method for wrapping steel structure column bases is to use plywood formwork. Typically, a suitable plywood formwork is selected first. Based on the size and shape of the column base, the plywood formwork is measured and cut. The cut plywood formwork is then wrapped around the column base, ensuring that the formwork fits tightly against the column base. Nails, bolts, or tape are used to secure the formwork firmly to prevent it from loosening or falling off during pouring. A level is used to check the verticality of the column base to ensure that it meets the design requirements. Concrete is then poured around the outside of the formwork. After the concrete reaches a certain strength, the plywood formwork is removed.

[0005] The above-mentioned plywood wrapping method has a long on-site construction time, high construction cost, and complicated steps. In addition, different sizes of plywood boards need to be cut into different sizes for steel structure column bases. After use, they cannot be reused, which is wasteful of wood. Therefore, a steel structure column base wrapping mold was invented to replace the traditional plywood formwork. Utility Model Content

[0006] To address the technical problems of the aforementioned plywood wrapping method, which involves long on-site construction time, high construction costs, cumbersome steps, and the need to cut plywood of different sizes for steel structure column bases, which cannot be reused after dismantling and is wasteful of wood, this utility model provides a column base wrapping steel structure mold.

[0007] A column base wrapping steel structure mold includes four single plates. Each single plate has a bent plate fixedly installed on its top and bottom walls. Each single plate has two perforated plates fixedly installed on the inner side wall at one end. Each perforated plate has a stiffening plate fixedly installed on its side wall for reinforcement. Each perforated plate has several through holes. Each single plate has a bolt and an oblong hole fixedly installed at the end away from the perforated plate. The bolt and oblong hole are mutually compatible. The bolt on the single plate can pass through any of the round holes on the adjacent perforated plates and be fixed.

[0008] Furthermore, each veneer is 3mm thick, 350mm wide, and 1500mm long. The bent board is integrally formed and fixed to the top and bottom of the veneer, with a bending width of 50mm and a length consistent with the veneer length.

[0009] Furthermore, the bolts and oblong holes on adjacent panels are compatible with each other. The oblong holes are 14mm wide and 50mm long, and can be finely adjusted with an accuracy of 1mm.

[0010] Furthermore, the two perforated plates are arranged in parallel, with a number of round holes evenly arranged on the perforated plates. Two stiffening plates are fixedly installed on the top side wall of the upper perforated plate and the bottom side wall of the lower perforated plate, respectively, with the two stiffening plates arranged in parallel.

[0011] Furthermore, the thickness of both the perforated plate and the stiffening plate is 6mm. The four single plates and the adjacent perforated plates are fixed together to form a square inner circumference, which wraps around the column base. The adjustable range of the square inner circumference is 650mm-1000mm.

[0012] Compared with the existing technology, the beneficial effects of this utility model are: compared with the traditional plywood wrapping method, it is not necessary to cut plywood according to the column base specifications on the construction site, saving on-site construction time, which helps to reduce construction costs and improve work efficiency. Moreover, the installation is simple, time-saving and labor-saving. After use, it can be disassembled and kept for the next use, realizing recycling, reducing costs, saving wood, and protecting the environment. Attached Figure Description
