[0024] The following is combined with Figure 1 To the attached Figure 8 The following is a detailed description of the application:
[0025] A device for reinforcing an aluminum alloy formwork with an inverted structure includes a formwork clamp 1, tie rods 2, bracing rods 3, and ground-stabilizing steel bars 4. The formwork clamp 1 comprises two U-shaped square steel bars 101 and a clamp connecting iron plate 102; the formwork clamp 1 can also be simply referred to as the clamp. The tie rods 2 comprise disc nuts 201 and threaded rods 202. The bracing rods 3 comprise a main rod 301, an upper crossbar 302, a middle connecting rod 303, a middle top bracing rod 304, a lower fixing rod 305, and a lower connecting rod 306. The construction steps include cutting and welding square steel to form U-shaped square steel 101; cutting rods according to pre-designed dimensions, the rods to be cut include main rod 301, upper cross rod 302, middle connecting rod 303, middle top support rod 304, lower fixed rod 305, and lower connecting rod 306, and welding the rods after processing the joints to form support rod 3; drilling holes in U-shaped square steel 101, and assembling the support rod 3 and U-shaped square steel 101 together, with two U-shaped square steels 101 in each group. 1 is welded by connecting iron plates 102; cut threaded rods 202, each side protruding from the clamp by no less than 100mm, and configure corresponding disc nuts 201; after the aluminum alloy template 5 is laid out and installed, install and adjust the clamp 1; then install the tie rod 2, the tie rod 2 is installed 50mm above the aluminum alloy template 5, and tighten the disc nuts 201; adjust the support rod 3, drill holes in the ground, and use ground fixing steel bars 4 to fix the support rod to the ground.
[0026] Figure 2 a shows the front view of the template fixture; Figure 2 Figure b shows a side view of the formwork fixture. The formwork fixture 1 in this embodiment is constructed from two U-shaped square steels 101 welded together using a connecting iron plate 102. The U-shaped square steels 101 are cut to size based on the inverted structure and the aluminum alloy formwork, and then welded together. The internal clearance width is consistent with the outer width of the aluminum alloy formwork in the inverted structure, effectively clamping the aluminum alloy formwork and preventing deformation and misalignment.
[0027] The size of the square steel is 40*60mm, and the thickness is not less than 3mm; the width of the connecting iron plate 102 is not less than 40mm, the length is 100mm, and the thickness is not less than 3mm.
[0028] like Figure 1 、 Figure 3 As shown, the tie rod 2 consists of a threaded rod 202 and a disc nut 201. When tightened, it creates the first horizontal force on the formwork fixture. The diameter of the threaded rod 202 is no less than 14 mm, and the disc nut 201 is compatible with the threaded rod 202. The threaded rod protrudes from the fixture 1 by no less than 100 mm on both sides, and the disc nut complies with national standards.
[0029] like Figure 1 、 Figure 4 As shown, the support rod 3 is welded together by a main rod 301, an upper crossbar 302, a middle connecting rod 303, a middle top support rod 304, a lower fixed rod 305, and a lower connecting rod 306. The diameter of the main rod should be no less than 16 mm, and the diameter of the other rods should be no less than 14 mm. The upper crossbar 302 crosses the formwork clamp 1, and the lower fixed rod 305 is fixed to the ground using ground-fixing steel bars 4 to form a support. The middle top support rod 304 is used in the middle to support the inner corner below the aluminum alloy formwork. The upper crossbar 302 is supported by the main rod 301 and the ground, forming a second horizontal force on the clamp 1. The middle top support rod 304 creates a third horizontal force and downward pressure on the aluminum alloy formwork through the middle connecting rod 303 and the main rod 301. The horizontal force and downward pressure can prevent the aluminum alloy formwork from expanding, shifting, and floating upward.
[0030] The strength requirement of the steel used in this example should not be lower than Q235. The welding quality of all welds must meet the second-level weld standard.
[0031] like Figure 1 、 Figure 5 — Figure 8 As shown, the construction method of the aluminum alloy formwork reinforcement device with an inverted structure having waterproof requirements includes the following steps:
[0032] Step 1: Processing U-shaped square steel 101. Cut and weld the U-shaped square steel according to the upper inverted structure and the size of the aluminum mold;
[0033] Step 2: Process the support rod 3. Cut the parts of the support rod 3 according to the designed size, and then weld them. The angle of the rod should be ensured during welding.
[0034] Step 3: Assemble the U-shaped square steel 101 and the bracing members 3. Each set consists of two welded U-shaped square steels 101 and two bracing members 3. After drilling the holes in the U-shaped square steel, begin assembling the bracing members 3. Insert the upper crossbars 302 of the bracing members 3 on both sides through the drilled holes in the U-shaped square steel 101, place the main member 301 between the two U-shaped square steels 101, and then weld the U-shaped square steels 101 together using the connecting iron plate 102, with three welds on each side.
[0035] Step 4: Cut the tension screw 202. The length of each side exceeds the clamp by no less than 100mm, and configure the matching disc nut 201;
[0036] Step 5: Construction preparation: transport the reinforcement device and the aluminum alloy formwork to the construction site, measure and lay out the upper structure, and prepare the inner positioning ribs;
[0037] Step 6: Install the aluminum alloy formwork and reinforcement devices. First install the aluminum alloy formwork and the outer positioning ribs, install the reinforcement devices, adjust the angle, and fix the support rods on the ground. The reinforcement devices should be installed every one meter.
