After the fastening is completed, it is convenient to construct the column template 300. The first back rib 110 and the second back rib 120 can be prefabricated in the factory, which is convenient for recycling and reducing costs. The template fastener structure uses a prefabricated combined first back rib 110 and a second back rib 120 to achieve the template fastening effect.

Through simple adjustment, it can be used for column template installation and fastening in different parts and projects. After installation, it occupies a small space and is more environmentally friendly, green and easy to operate.

[0027] See also Figure 1 , Figure 2 and Figure 3 The first fixed connector 200 includes a nut 210 and a screw rod 220. The two ends of the screw rod 220 pass through the two ends of the template unit 100 respectively, and the nut 210 is threadedly connected to the end of the screw rod 220.

[0028] See also Figure 2 and Figure 3 One end of the first back rib 110 is connected to the second back rib 120, and the other end of the first back rib 110 is provided with a first fixing portion 111, one end of the second back rib 120 is connected to the first back rib 110, and the other end of the second back rib 120 is provided with a second fixing portion 121, and the two ends of the screw rod 220 pass through the first fixing portion 111 and the second fixing portion 121 respectively and are threadedly connected to the nut 210.

[0029] See also Figure 2 A first fixing surface 112 is provided on the first fixing portion 111, and the first fixing surface 112 protrudes from the outer surface of the first back rib 110 and forms a first angle between the outer surfaces of the first back rib 110.

[0030] See also Figure 1 The cross section of the column template 300 is square, the template units 100 are arranged along the four sides of the column template 300, adjacent template units 100 are perpendicular to each other, the first angle and the second angle are both 45°, and the first fixing surface 112 and the second fixing surface 122 are parallel to each other.

[0031] Specifically, the template fastener structure includes four template units 100 of the same size, four first back ribs 110 of the same size, eight second fixed connectors 130 of the same size, and four second back ribs 120 of the same size. The first back ribs 110 and the second back ribs 120 of different lengths are flexibly combined and assembled with screws and nuts to form a fastening effect on the column template 300. After the fastening is completed, it is convenient to carry out the construction of the column template 300. The first back ribs 110 and the second back ribs 120 are made separately, and the manufacturing process is factory-molded and mass-produced. When used, aluminum alloy back ribs of different lengths and specifications can be produced according to different column sizes. Aluminum alloy back ribs of the same width The fasteners used are nuts and screws of related specifications, so that as long as different aluminum alloy back ribs are used, columns of different sizes can be built, and the fasteners remain unchanged and can be recycled, reducing material costs; each component is simply classified and placed on the construction site, which is easy to take and complete the fastening of the column formwork 300, and the aluminum alloy back ribs can be expanded and retracted by adjusting the position of the nut to adapt to different column sizes and can be recycled many times; each component can be disassembled and used, which can better utilize the turnover rate of fasteners, and will not make fasteners unusable for template back ribs of different sizes, which greatly reduces the disadvantage of large material loss in construction, the construction process has a high degree of environmental protection, and improves the reliability of green construction.

[0032] See also Figure 2, a slot 140 for inserting the second back rib 120 is provided on the first back rib 110, and both the first back rib 110 and the second back rib 120 are straight back ribs, and the slot 140 is arranged along the length direction of the first back rib 110. Specifically, the back rib in the building refers to a concave or convex structure formed inside or outside the wall. Back ribs can bring many advantages to buildings. The existence of back ribs can increase the rigidity and stability of the wall, enabling it to withstand greater loads and resist external forces, thereby enhancing the structural safety of the building; through the concave back rib design, an additional sense of space can be created for the building; the back rib can be used to adjust the sound propagation and absorption inside the building, reduce noise reflection and resonance, and improve the quality of the acoustic environment. By reasonably designing and arranging the back ribs, the sound quality and comfort inside the building can be improved; the back ribs can form an air layer or fill insulation materials in the wall, thereby increasing the thermal insulation performance of the building. This helps to reduce energy consumption, improve the energy efficiency performance of the building, and create a more comfortable indoor environment.

[0033] See also Figure 2 The first back rib 110 is provided with a first through hole 113, the second back rib 120 is provided with a second through hole 123 arranged opposite to the first through hole 113, and the second fixing connector 130 passes through the first through hole 113 and the second through hole 123 to fix the first back rib 110 and the second back rib 120 together.

[0034] See also Figure 2 The second fixed connection member 130 includes a screw, which passes through the first through hole 113 and the second through hole 123 to connect the first back rib 110 and the second back rib 120. The screw connection can provide a high connection strength, so that the connected parts are stable and can withstand large forces and loads; the screw connection is easier to operate and assemble than other connection methods (such as welding or adhesives). Only tools such as screwdrivers or wrenches are needed to complete the connection, without the need for additional special equipment or technology; screw connection is different from permanent connection methods such as welding. The screw connection is reversible, that is, it can be easily disassembled and reconnected. This is very convenient when maintenance, replacement or adjustment is required; screw connection is a relatively economical connection method because the cost of screws and nuts is relatively low, and the installation and maintenance costs are relatively low.

[0035] As a preferred embodiment of the present application, the first back rib 110 and the second back rib 120 are both made of aluminum alloy material. Aluminum alloy is lightweight but has high strength and strong impact resistance, so that the template fastener structure can achieve a fastening effect, avoiding the existing steel pipe combination fasteners using steel materials. The fasteners are prone to collision with steel or other hard objects during use. In addition, the construction site environment is often open-air construction, and it is very easy to rust on rainy and humid days, resulting in large material loss, great waste, and high cost.

[0036] This application also provides a column template, see Figure 1 , including the template fastener structure of any one of the above embodiments, multiple template fastener structures are arranged at intervals along the height direction of the column template 300, and the template fastener structure of the column template is prefabricated through engineering, which reduces on-site processing and speeds up the construction progress; it is easy to install, and no waste is generated during the process, achieving the requirements of green construction projects; each component can be recycled and reused multiple times, improving the degree of green environmental protection; the same set of fastener equipment can be flexibly disassembled and is suitable for different projects and engineering parts.
