[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figure 1 As shown, a fully enclosed aluminum alloy formwork for a flue includes a closed inner formwork. The inner formwork is composed of multiple aluminum formworks facing different directions. Each aluminum formwork includes four circumferentially distributed first aluminum formworks 1 and four second aluminum formworks 2 respectively disposed between adjacent first aluminum formworks 1. The first aluminum formworks 1 and the second aluminum formworks 2 enclose a square, fully enclosed small space. Figure 4As shown, the first aluminum template 1 is trapezoidal, and includes a first panel 11 and first connecting plates 12 disposed on both sides of the first panel 11; Figure 5 As shown, the second aluminum template 2 includes a triangular second panel 21 and second connecting plates 22 disposed on both sides of the second panel 21. The first connecting plate 12 abuts against and connects with the second connecting plate 22. The first panel 11 and the second panel 21 are spliced ​​to form a flat surface. The inner side of the first aluminum template 1 is provided with a first reinforcing plate, and the inner side of the second aluminum template 2 is provided with a second reinforcing plate. The bottom of the inner template is provided with a leak-proof angle aluminum 5, which is connected to the inner template by bolts. The angle aluminum 5 is a split structure, corresponding to the first aluminum template 1 and the second aluminum template 2 respectively.

[0023] like Figure 2 , 3 As shown, the back of the first aluminum template 1 is provided with a reinforcing self-locking back rib 4 within the fully enclosed small space. The reinforcing self-locking back rib 4 cooperates with the reinforcing screw 3 to form a reinforcing device. One type of reinforcing self-locking back rib 4 structure includes an upper reinforcing member 41, an upper connecting plate 43 connected to the upper reinforcing member 41, a lower reinforcing member 42 located below the upper reinforcing member 41, a lower connecting plate 44 connected to the lower reinforcing member 42, and a tie rod nut 45 located between the upper reinforcing member 41 and the lower reinforcing member 42. The upper connecting plate 43 and the lower connecting plate 44 are fixedly connected to the first reinforcing plate by bolts and nuts, respectively. The nuts can be welded to the upper connecting plate 43 and the lower connecting plate 44. Figure 6 As shown, another type of reinforced self-locking back rib 4 structure includes an upper reinforcement member 41, a lower reinforcement member 42 located below the upper reinforcement member 41, and a tie rod nut 45 located between the upper reinforcement member 41 and the lower reinforcement member 42. The tie rod nut 45 is welded and fixed to the back of the reinforced self-locking back rib 4 via a fixing plate 47. The reinforced self-locking back rib 4 is provided with a corner plate, which can be welded to the upper reinforcement member 41 or the lower reinforcement member 42. The corner plate is connected to the first reinforcing plate through the cooperation of bolts and nuts. The tie rod nut 45 cooperates with the reinforcing screw 3. The aluminum template is provided with a through hole corresponding to the tie rod nut 45. One end of the reinforcing screw 3 passes through the through hole and is threadedly connected to the tie rod nut 45. A support tube 46 is also provided between the upper reinforcement member 41 and the lower reinforcement member 42. The support tube 46 is located on both sides of the tie rod nut 45, so that the upper reinforcement member 41 and the lower reinforcement member 42 form a stable whole. The upper reinforcement 41 and the lower reinforcement 42 have the same structure and are both trapezoidal tubes. One side of the trapezoidal tube abuts against the inner side of the aluminum template, and both ends of the trapezoidal tube are beveled to avoid interference between adjacent trapezoidal tubes.

[0024] The template installation and disassembly process is as follows:

[0025] 1. Before the template is installed, the space inside the flue is too small for personnel to enter and operate. When installing and disassembling aluminum alloy templates, to prevent materials from falling and becoming impossible to remove, steel bars must be inserted into the cross-shaped reinforcement holes of the original template back rib bolts at the bottom of the template to prevent the template from falling to the bottom.

[0026] 2. Before installing the formwork, positioning steel bars should be installed around the inner edge of the flue to ensure that each formwork is reinforced to prevent it from shrinking inward and to ensure the clear dimensions of the flue.

[0027] 3. Template installation: First, install the flue box template. Apply release agent before template installation. No dowels are needed at the bottom. Dowels are used to connect the top 300mm to form a closed structure. Then, install the template outside the flue. While installing the template, threaded rod sleeves are inserted. After sealing the template, the threaded rods around the template are balanced and reinforced. After the template is installed, angle iron hangers are installed at the flue opening to prevent the template from sagging.

[0028] 4. After the formwork is installed, concrete is poured. The formwork must be monitored to prevent it from bulging or running due to vibration during concrete pouring. 6-8 hours after the formwork is poured and the concrete has initially set, workers should be arranged to loosen the reinforcing bolts and tap the formwork inside the flue.

[0029] 5. 12 hours after the concrete is poured, first remove the flue formwork. Use the flue reinforcement screw to remove the middle double-sloped formwork first. After the internal jacking is out, when taking out the screw, you need to hang the formwork with a fall arrest rope to prevent the formwork from falling to the bottom of the flue. After removing the 4 double-sloped plates inside the flue, remove the other inside corners. Before removing them, hang the fall arrest rope and use a crowbar to remove them.

[0030] 6. Repeat the above sequence to install and remove the next layer of templates.
