[0025] First embodiment: Please refer to Figure 1 (Refer to) Figures 2 to 7 This embodiment provides a formwork support device for pouring irregularly shaped steel concrete columns, which mainly includes multiple sets of embedded plate assemblies 1, multiple columns 2, multiple connecting structures 3, and multiple support templates 4. The multiple sets of embedded plate assemblies 1 are respectively arranged at the bottom of the corresponding irregularly shaped steel concrete columns 5 and are adapted to the corresponding irregularly shaped steel concrete columns 5. Simultaneously, the columns 2 are arranged on one side of the corresponding irregularly shaped steel concrete columns 5 and are hinged to the corresponding embedded plate assemblies 1. Furthermore, the multiple connecting structures 3 are arranged along the height direction of the columns 2 and are sequentially connected to the multiple columns 2. The multiple support templates 4 are filled in a grid-like structure jointly formed by the columns 2, connecting structures 3, and irregularly shaped steel concrete columns 5, and each support template 4 is connected to two adjacent columns 2. The support templates 4 are provided with grouting ports 19 to facilitate concrete pouring, allowing concrete to be poured into the support templates 4 through the grouting ports 19.

[0026] Using this device for formwork erection of irregularly shaped steel-concrete columns 5 enables batch and prefabricated installation, ensuring consistent construction quality. Its rotatable column 2 and tensioning reinforcement method for the connecting structure 3 are convenient, safe, and reliable, reducing operational risks, improving work efficiency, and allowing for reuse to lower construction costs. Ultimately, it enhances the erection efficiency and pouring quality of irregularly shaped steel-concrete columns 5.

[0027] Furthermore, its embedded plate assembly 1 includes an embedded plate 6, two connecting ear plates 7, a positioning rib plate 8, and a connecting shaft 9; wherein, the embedded plate 6 is set at the bottom of one side of the irregular steel concrete column 5 and is fixed to the ground by multiple bolts 10 and pads 11; at the same time, the connecting ear plates 7 and the positioning rib plate 8 are respectively installed on the embedded plate 6 and welded to one side of the irregular steel concrete column 5 respectively; in addition, the connecting shaft 9 is installed between the connecting ear plates 7; the bottom end of the column 2 is hinged to the connecting shaft 9.

[0028] Furthermore, the column 2 includes a vertical support 12, an expansion joint, an adapter 13, and an anchor 14. The vertical support 12 is positioned on one side of the corresponding irregular-shaped reinforced concrete column 5. The two ends of the expansion joint are connected to one end of the vertical support 12 and one end of the adapter 13, respectively. The other end of the adapter 13 is connected to the anchor 14. The anchor 14 is hinged to the embedded plate assembly 1. In addition, the vertical support 12 has multiple connecting holes 15 spaced along its height for connecting to the connecting structure 3, facilitating the installation and fixing of the wire rope 16 in the connecting structure 3. Furthermore, U-shaped slots for engaging with the support template 4 are provided on both opposite sides of the column 2, allowing the support template 4 to be inserted and fixed. By setting the adapter 13 and the anchor 14, the installation angle of the vertical support 12 can be adaptively adjusted, making it suitable for the support construction of irregular-shaped reinforced concrete columns 5 with different shapes and installation angles.

[0029] Furthermore, its connection structure 3 includes steel wire ropes 16, multiple connecting anchors 17, and expansion joints 18; multiple steel wire ropes 16 connected in sequence are respectively connected to multiple columns 2 in sequence; the connecting anchors 17 are respectively sleeved on the ends of two adjacent steel wire ropes 16, and the expansion joints 18 are connected between two adjacent connecting anchors 17 with adjustable length. By designing connecting anchors 17 and expansion joints 18 at the ends of the steel wire ropes 16, the overall tension of the steel wire ropes 16 can be adaptively adjusted, and thus the steel wire ropes 16 can be extended or retracted according to the tightness of the support template 4, making the operation flexible and convenient.

[0030] This device can more quickly solve the problem of rapid assembly and installation of irregularly shaped columns. Its working principle is based on leverage; it uses the connecting shaft 9 below the column 2 as a fulcrum to rotate and change the support angle to adapt to the support needs of irregularly shaped reinforced concrete columns 5. Support templates 4 are installed between the upper parts of the columns 2, and then the entire support template 4 is bundled and adjusted using steel wire ropes 16, achieving overall installation of the support template 4. This solves the problems of complex and inconvenient construction processes in traditional irregular column formwork. Its design is reasonable, reusable, and allows for fast installation and disassembly, with simple operation. Compared with traditional templates, steel pipes, and tie rods, this application avoids template breakage. Compared with the existing technology of manually cutting and assembling small template pieces, it is more efficient and produces better concrete pouring quality. By fixing the support template 4 through U-shaped slots between adjacent columns 2, the amount of cutting and assembling of the support template 4 is reduced, solving the problem of concrete leakage and difficulty in controlling pouring quality caused by loose joints between scattered small panels. The device uses a design of 16 horizontal steel wire ropes for tensioning and binding to fix the template system, which solves the problem of the traditional method of welding and fixing with tie rods, which is complicated and prone to breakage, and improves installation efficiency and stability.

[0031] In summary, this application provides a formwork support device for pouring irregularly shaped steel concrete columns. It uses multiple sets of embedded plate assemblies 1 to fix the entire structure, and connects multiple rotatable columns 2 to the upper part of the embedded plate assemblies 1. This allows it to be used for supporting irregularly shaped columns of various structures, solving the problems of complex procedures and inconvenient construction associated with traditional irregular column formwork, effectively improving construction efficiency and broad applicability. Furthermore, it allows for batch and modular installation, ensuring consistent construction quality. Moreover, the use of rotatable columns 2 and multiple connecting structures 3 for reinforcement makes the support operation of irregularly shaped columns more convenient, safe, and reliable, reducing operational risks, improving work efficiency, and allowing for reuse while reducing construction costs.

[0032] Second embodiment: In this embodiment, a method for supporting the formwork for casting irregularly shaped steel concrete columns based on the formwork support device in the first embodiment is provided; the method mainly includes the following steps: Draw the installation baseline lines for the embedded plate assembly 1 around the bottom of the irregular steel-concrete column 5 to be installed, and arrange the installation points of the embedded plate assembly 1; embed the embedded plate assembly 1 according to the designed points, ensuring that its installation position and the orientation of the embedded plate are accurate; weld the ear plates and stiffening plates according to the inclination angle of the outer side of the irregular steel-concrete column 5, ensuring the quality of the welding and the installation angle of the ear plates; install the column 2 and adjust the angle of the column 2; install the support template 4 in the U-shaped groove of the column 2, ensuring that the support template 4 is secure during installation. Insert the U-shaped groove to a depth that minimizes construction gaps; any small gaps must be sealed tightly with template tape. Pass the wire rope 16 through the rope hole on the column 2, connect the connecting anchor 17 and expansion joint 18 at the end of the wire rope 16, and adjust the tension of the wire rope 16 to ensure it is firmly tensioned and evenly stressed. After installation, inspect the support formwork 4. If there are no problems, begin pouring concrete from the pouring port at the top of the support formwork 4. After pouring and curing, remove the support formwork 4.

[0033] In summary, this application provides a support method based on a formwork support device for pouring irregularly shaped steel concrete columns. This method involves marking installation baselines around the location of the irregularly shaped steel concrete column 5 to be installed, embedding the embedded plate assembly 1 according to the designed points, welding the embedded plate assembly 1 according to the inclination angle of the irregularly shaped steel concrete column 5, installing the support formwork 4 in the U-shaped slot of the column 2, and connecting the connecting structure 3 to multiple columns 2 respectively. This enables the support and reinforcement of the irregularly shaped column, making the support operation of the irregularly shaped column more convenient, safe, and reliable, reducing operational risks, improving work efficiency, and allowing for reuse while reducing construction costs.
