[0022] See Figure 1-2 This embodiment discloses a splicing node of a metal template 10 and a wooden template 20, including a metal template 10, a wooden template 20, a metal square channel 30, and a wooden beam 40; the metal template 10 includes a splicing part 11 and a connecting part 12, and the splicing part 11 and the connecting part 12 are connected to each other; the bottom wall 33 of the metal square channel 30 is connected to the connecting part 12, and an installation cavity is provided in the metal square channel, in which the wooden beam 40 is accommodated; the wooden template 20 is connected to the wooden beam 40, and the wooden template 20 is aligned with the splicing part 11 of the metal template 10.

[0023] In this design, the splicing joint between the metal formwork 10 and the wooden formwork 20 is achieved by adding a metal square channel component 30 and a wooden beam 40. This method avoids directly fixing the metal formwork 10 and the wooden formwork 20 together with nails, simplifying the connection operation and structure, and resulting in better concrete molding at the joint between the metal formwork 10 and the wooden formwork 20. Using this joint, the metal formwork 10 can be used on a large scale, reducing the amount of wooden formwork used, increasing the number of times the metal formwork 10 can be reused, and ultimately reducing costs.

[0024] In this embodiment, the metal square channel 30 includes a top wall 31, a side wall 32, and a bottom wall 33, which together form an installation cavity. It is understood that the metal square channel 30 is a C-shaped channel, wherein the opening of the C-shaped channel is opposite to the wooden template 20.

[0025] In this embodiment, the splicing node further includes a top bolt 50 and a bottom bolt 60. The top bolt 50 passes through the top wall 31 of the metal square channel 30 and abuts against the top surface of the timber 40. The bottom bolt 60 passes through the connecting part 12 and the bottom wall 33 in sequence and abuts against the bottom surface of the timber 40. The top bolt 50 and the bottom bolt 60 are used to jointly limit the timber 40. The bottom bolt 60 is also used to connect the metal template and the metal square channel 30. The splicing node also includes a side bolt 70. The side bolt 70 passes through the side wall 32 of the metal square channel 30 and abuts against one side of the timber 40. The other side of the timber 40 is connected to the wooden template 20. The side bolt 70 is used to adjust the position of the timber 40 so that the wooden template 20 is aligned with the splicing part 11 of the metal template 10. The top bolt 50 and bottom bolt 60 are used to fix the timber 40. The side bolt 70 can push and support the timber 40 and the wooden template 20 to move during rotation, so that the wooden template 20 is aligned with the metal template 10.

[0026] In this embodiment, the bottom of the wooden formwork 20 contacts the connecting part 12, and the outer surface of the wooden formwork 20 is aligned with the outer surface of the splicing part 11. The wooden formwork 20 and the metal formwork 10 are spliced ​​together to form a flat surface, ensuring good molding effect of the concrete 1.

[0027] In this embodiment, the bottom wall 33 of the metal square channel 30 is provided with a plurality of spaced-apart bottom wall 33 bolt holes, a plurality of spaced-apart top wall 31 bolt holes, and a plurality of spaced-apart side wall 32 bolt holes. The plurality of bottom wall 33 bolt holes are used to insert bottom bolts 60, the plurality of top wall 31 bolt holes are used to insert top bolts 50, and the plurality of side wall 32 bolt holes are used to insert side bolts 70. It can be understood that the metal square channel 30 is provided with a plurality of bolt holes in advance to facilitate the fixing of the timber 40 by means of multiple top bolts 50, bottom bolts 60, and side bolts 70.

[0028] In this embodiment, the distance between the top wall 31 and the bottom wall 33 of the metal square channel 30 is greater than the height of the wooden beam 40. The top wall 31 and the bottom wall 33 of the metal square channel 30 have the same width, and the width of both the top wall 31 and the bottom wall 33 of the metal square channel 30 is greater than the width of the wooden beam 40.

[0029] Specifically, the cavity size of the metal square channel 30 with bolt holes should be 2-3 cm larger than the cross-sectional size of the timber 40. Given that the timber 40 on the market is mostly 50×80mm or 40×90mm, the cavity size of the metal square channel 30 should preferably be 70×110mm. The metal square channel 30 has bolt holes on three sides, and the spacing between them should preferably be 500mm.

[0030] In this embodiment, the timber 40 and the wooden template 20 are fixedly connected by fastening screws. Specifically, the fastening screws are iron nails.

[0031] In this embodiment, the metal template 10 is a C-groove shaped aluminum template, and the upper and lower ends of the splicing part 11 are respectively connected to two connecting parts 12. The metal template 10 can also be made of other metal materials, such as steel, magnesium alloy, etc. The bolt hole spacing can be adjusted according to actual needs, but it is recommended that the spacing not exceed 1m, otherwise the reinforcement effect may be poor.

[0032] During installation, use bottom bolts 60 to fix the aluminum template to the aluminum alloy square channel. Then install the wooden beam 40 and wooden template 20 in sequence. Fix the wooden template 20 and wooden beam 40 with nails. Use side bolts 70 to adjust the position of the wooden beam 40 and wooden template 20 so that the wooden template 20 is aligned with the side of the aluminum template C channel. Finally, fix the top bolts.

[0033] This solution provides an efficient joint method for combining aluminum and wooden formwork. This joint allows for the application of aluminum formwork in non-standard floor plans, significantly expanding its applicability. For example, this joint can be used for the walls and columns of basements in building construction, enabling large-scale application of aluminum formwork, reducing the amount of wooden formwork used, increasing the turnover rate of aluminum formwork, and lowering overall costs. Specifically, aluminum formwork is used for the lower part of the walls and columns, while wooden formwork is used for the top of the walls and columns and beams / slabs, with this joint used at the connection points.

[0034] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
