[0002] In recent years, architectural aluminum alloy formwork has been widely used in construction projects due to its high construction efficiency and good comprehensive economic benefits. A large amount of practical experience and statistical data show that aluminum alloy formwork has higher economic and social benefits instead of traditional wooden formwork. On the one hand, when aluminum alloy formwork is used for construction, it can be formed in one time and can meet the standards of plain concrete formwork without plastering, saving a lot of labor costs. At the same time, aluminum alloy formwork also has a large number of turnovers. Research data show that the turnover of aluminum alloy formwork can be as high as more than 300 times, while the turnover of wooden formwork can only reach more than 10 times. When the turnover of aluminum alloy formwork exceeds thirty times, the cost of aluminum alloy formwork will be lower than that of wooden formwork, and the residual value rate of aluminum alloy material is as high as 30%, so the use of aluminum alloy formwork can produce better economic benefits. On the other hand, the construction of aluminum alloy formwork does not require high personnel, can promote the employment of a large number of rural population, and the construction waste generated after the construction of aluminum alloy formwork is almost zero, which also produces huge economic and social benefits in terms of environmental protection.

[0036] The width of the connecting member 32 in the X-axis direction is smaller than the distance from the end of the plane plate 1 in the X-axis direction to the surface of the side support plate 31, thereby ensuring seamless connection between the two aluminum alloy templates along the X-axis direction, and eliminating the influence of the connecting seam between the aluminum alloy templates on the construction appearance quality; the distance between the two side support plates 31 is equal to the length of the stiffening rib side plates 2, and the distance between the two stiffening rib side plates 2 is less than or equal to the length of the stiffening rib connecting plate 3, thereby ensuring seamless connection between the two aluminum alloy templates along the Y-axis direction, and eliminating the influence of the connecting seam between the aluminum alloy templates on the construction appearance quality.

[0037] The two stiffening rib side plates 2 are welded end to end with the two side support plates 31 to form a groove with the plane plate 1; the connecting member 32 includes a plurality of integrally formed T-shaped latches 321 for connecting two adjacent aluminum alloy templates, and the plurality of T-shaped latches 321 are sequentially extended vertically and along the X-axis direction to the outside of the groove for connection.

[0038] like Figure 3 As shown, the T-shaped key 321 includes a first connecting block 3211 and a second connecting block 3212 which are connected in sequence. The first connecting block 3211 is vertically connected to the side support plate 31 along the X-axis direction, and the upper surface of the first connecting block 3211 is aligned with the edge of the side support plate 31 away from the plane plate 1; the second connecting block 3212 is vertically connected to the first connecting block 3211 along the X-axis direction, and the center line of the second connecting block 3212 in the X-axis direction coincides with the center line of the first connecting block 3211 in the X-axis direction; the thickness of the first connecting block 3211 is less than the thickness of the second connecting block 3212.

[0039] like Figure 4 As shown, a clamping structure used for connecting the aluminum alloy templates includes two clamping members 4 and connecting bolts 5. The clamping members 4 include multiple slots that match the T-shaped keys 321. The two clamping members 4 are clamped with each other through the multiple slots and the multiple T-shaped keys 321 of the connecting member 32; a connecting bolt hole 46 is opened in the middle position of the clamping member 4; the connecting bolt 5 is inserted into the connecting bolt hole 46 and passes through the clamping members 4 clamped at the upper and lower positions of the connecting member 32 in turn to connect and fix the aluminum alloy templates into a whole.

[0040] The clamping member 4 includes a first clamping block 41, a second clamping block 42, a third clamping block 43, a fourth clamping block 44, and a fifth clamping block 45; the fifth clamping block 45 is symmetrically connected to the fourth clamping block 44, the third clamping block 43, the second clamping block 42, and the first clamping block 41 on both sides; one end of the first clamping block 41, the second clamping block 42, the third clamping block 43, the fourth clamping block 44, and the fifth clamping block 45 are aligned along the width direction, and the other end forms a concave-convex structure that is mutually engaged with a plurality of T-shaped latch keys 321 of the connecting member 32; the two first clamping blocks 41, the two second clamping blocks 42, the two third clamping blocks 43, the two fourth clamping blocks 44, and the fifth clamping block 45 are integrally formed.

[0041] The first clamping block 41 and the third clamping block 43 have the same thickness; the second clamping block 42 and the fourth clamping block 44 have the same thickness; the thickness of the fifth clamping block 45 is greater than or equal to the thickness of the first clamping block 41, the thickness of the first clamping block 41 is greater than the thickness of the second clamping block 42, and the fifth clamping block 45 is symmetrically connected to the fourth clamping block 44, the third clamping block 43, the second clamping block 42, and the first clamping block 41 on both sides along the positive and negative directions of the X-axis.

[0042] like Figure 5 As shown, the fifth clamping block 45 is drilled with a connecting bolt hole 46 along the center line of the Z-axis direction to match the connecting bolt 5.

[0043] like Figure 6 As shown, the connecting bolt 5 includes a screw rod 51, a nut 53, and a gasket 54.

The screw rod 51 and the nut 55 are integrally formed.

[0044] like Figure 7 As shown, the sum of twice the thickness of the fourth clamping block 44 plus the thickness of the second connecting block 3212 is greater than twice the thickness of the fifth clamping block 45, and the width of the first connecting block 3211 in the X-axis direction is correspondingly smaller than the width of the fourth clamping block 44 and the second clamping block 42 in the X-axis direction, and a margin gap 47 is formed when the connecting member 32 and the clamping member 4 are clamped together. The margin gap 47 is conducive to the upper and lower bite of the connecting member 32 and the clamping member 4, thereby avoiding the occurrence of mismatch between the connecting member 32 and the clamping member 4 due to processing errors.

[0046] (1) The connecting pieces 32 of the two aluminum alloy templates are engaged and fastened with the clamping pieces 4, and the upper and lower connecting bolt holes 46 of the clamping pieces 4 are aligned. The screw rod 51 is passed through the connecting bolt hole 46 from bottom to top, and after the gasket 54 is placed, the nut 53 is tightened to ensure that the connecting piece 32 and the clamping piece 4 are tightly fitted and fixed to form a whole, thereby realizing the connection of the two aluminum alloy templates.

[0047] (2) During disassembly, it is only necessary to loosen the nut 53 and pull out the clamping member 4 and the connecting bolt 5 as a whole along the y-axis direction, without the need to separate the clamping member 4 from the connecting bolt 5. This overall disassembly method saves disassembly time and improves construction efficiency.
