Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a support device for encasing concrete at the base of a steel column. Background Technology

[0002] In industrial buildings, warehousing and logistics structures are mostly portal steel frame structures. To facilitate loading and unloading, the height difference between the inside and outside of the warehouse is about 1.5 meters, and the height difference between the column base and the warehouse interior can reach 2 meters. Therefore, the steel column base requires high-support formwork construction with an outer concrete covering, and the quality of the outer concrete covering is crucial to the service life of the steel column. Traditional construction methods often use wooden formwork, which is difficult to operate during construction due to the high support height, and the formwork is difficult to reinforce. Moreover, during the formwork turnover process, uneven formwork surfaces, numerous tie bolt holes, and difficulty in quality control are produced. Furthermore, the installation and dismantling process of traditional formwork is very time-consuming, especially for high-support formwork construction, where the formwork is quite high, requiring workers to work at heights to install and dismantle the formwork piece by piece. Each construction project requires the re-fabrication of formwork, which cannot be reused, increasing material and time costs. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a support device for the concrete encasing of steel column bases, which is particularly suitable for the construction of high formwork concrete encasing steel column bases in portal frame structures.

[0004] The technical solution adopted by this utility model is as follows: Firstly, a support device for encasing concrete at the base of a steel column is provided, which is composed of multiple sets of standard section modules connected together. The standard section module includes a frame unit and a template, and the frame unit is connected to the template.

[0005] Furthermore, the frame unit includes an upper corner piece, a lower corner piece, a left corner piece, and a right corner piece. One end of the upper corner piece is connected to one end of the left corner piece, the other end of the upper corner piece is connected to one end of the right corner piece, the other end of the left corner piece is connected to one end of the lower corner piece, and the other end of the right corner piece is connected to the other end of the lower corner piece.

[0006] Furthermore, the frame unit also includes a stiffening flat member, the two ends of which are connected to the left corner piece and the right corner piece, respectively.

[0007] The advantages and positive effects of this utility model are as follows: Due to the adoption of the above technical solution, standardized standard section modules are used, which can be flexibly combined according to the specific dimensions of the outer concrete. This modular design not only simplifies the construction process, but also makes the formwork devices of different projects interchangeable, improving the versatility and flexibility of the equipment. Stiffening flat members are added between the formwork and frame units, which enhances the rigidity and deformation resistance of the entire structure. This not only ensures the stability during the concrete pouring process, but also extends the service life of the device. Attached Figure Description

[0015] 200. Template Detailed Implementation

[0016] The present disclosure will now be described more fully with reference to the accompanying drawings, which illustrate exemplary embodiments of the present disclosure. The technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present disclosure, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative effort are within the scope of protection of the present disclosure.

[0017] like Figure 1-3 As shown, this utility model provides a support device for encasing concrete at the base of a steel column, which is composed of multiple sets of standard section modules connected together. The standard section module includes a frame unit 100 and a template 200, and the frame unit 100 is connected to the template 200.

[0018] The template 200 is directly connected to the frame unit 100. Its size can be adjusted according to actual needs, making it suitable for steel columns of different specifications.

[0019] In one embodiment, the frame unit 100 includes an upper corner piece 101, a lower corner piece 102, a left corner piece 103, and a right corner piece 104. One end of the upper corner piece 101 is connected to one end of the left corner piece 103, and the other end of the upper corner piece 101 is connected to one end of the right corner piece 104. The other end of the left corner piece 103 is connected to one end of the lower corner piece 102, and the other end of the right corner piece 104 is connected to the other end of the lower corner piece 102.

[0020] The upper corner bracket 101 and lower corner bracket 102 are used to fix the formwork 200 and provide direct vertical support, while the left corner bracket 103 and right corner bracket 104 are used to fix the formwork 200 and provide direct horizontal support. Standardized modular sections are used, allowing for flexible combination according to the specific dimensions of the encased concrete. This modular design not only simplifies the construction process but also makes the formwork devices interchangeable between different projects, improving the equipment's versatility and flexibility. The upper corner bracket 101, lower corner bracket 102, left corner bracket 103, and right corner bracket 104 are made of materials including, but not limited to, high-strength structural steel and aluminum alloy. High-strength structural steel has the advantage of being able to withstand large loads, making it suitable for large construction projects, facilitating the manufacture of corner brackets with complex shapes, and allowing for enhanced joint strength through welding or bolting. Aluminum alloy has the advantage of being lighter than steel, facilitating transportation and installation, reducing the requirements for lifting equipment, performing excellently in humid environments, and requiring no additional anti-corrosion measures.

[0021] like Figure 4 As shown, in one embodiment, the frame unit 100 further includes a stiffening flat member 105, the two ends of which are connected to the left corner member 103 and the right corner member 104, respectively.

[0022] To further enhance the stability of frame unit 100, stiffening flat members 105 are specially designed. The two ends of stiffening flat members 105 are firmly connected to the left corner member 103 and the right corner member 104, respectively, thereby improving the overall frame's resistance to deformation and ensuring that no displacement or deformation occurs during concrete pouring. The addition of stiffening flat members between the formwork and frame unit enhances the rigidity and resistance to deformation of the entire structure, ensuring stability during concrete pouring and extending the service life of the device. The stiffening flat members are made of materials including, but not limited to, stainless steel, aluminum alloy, glass fiber reinforced plastic, and carbon fiber reinforced plastic. Glass fiber reinforced plastic and carbon fiber reinforced plastic offer the advantage of providing extremely high strength while maintaining very low density, making them ideal for electrically sensitive areas, resistant to acid, alkali, and salt corrosion, and adaptable to various harsh environments.

All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
