[0002] Traditional winter construction exterior wall insulation measures generally involve manually hanging rock wool, quilts and other insulation materials on the outside of the aluminum alloy formwork, using heaters, coal stoves and other methods to heat the room, and cleaning the insulation materials after the concrete is cured. This process is repeated over and over again, wasting manpower and prolonging the construction cycle. It is difficult to completely cover the corners of the exterior wall with insulation materials, which can easily cause air leakage, and there are certain safety risks for workers working at heights. The heat generated by the indoor temperature rise cannot be transferred to the protective layer, resulting in reduced concrete strength and cracks and other quality problems. The insulation effect is often not particularly ideal when performing thermal calculations. Therefore, it is necessary to invent an aluminum alloy formwork exterior wall heating device to solve the above problems.

[0020] The utility model provides an aluminum alloy formwork exterior wall heating device as shown in Figures 1-4, comprising an aluminum alloy formwork 1, wherein aluminum alloy panel end ribs 2 are fixed on all sides of one side of the aluminum alloy formwork 1, an aluminum alloy surface accommodating cavity 3 is formed between the aluminum alloy formwork 1 and the aluminum alloy panel end rib 2, a plurality of array-arranged accommodating cavity inner ribs 4 are fixed between the inner side wall of the aluminum alloy panel end rib 2 and the inner wall of the aluminum alloy surface accommodating cavity 3, the side walls of the two groups of aluminum alloy formworks 1 are fixed together, a plurality of threaded holes are opened on the side surface of the aluminum alloy panel end rib 2, and fixing bolts 5 are screwed on the inside of the threaded holes, and locking nuts 6 are screwed on the surface of the fixing bolts 5, and the locking nuts 6 are abutted against the side surface of the aluminum alloy panel end rib 2, and the fixing bolts 5 and locking nuts 6 are used to assemble multiple pieces of aluminum alloy formworks 1 as a large integrated formwork. When each layer of formwork is constructed, the exterior wall formwork is hoisted as a whole to the upper layer, and there is no need to repeatedly lay the heating wire 7 and the insulation board 12, which reduces the labor input of hanging and cleaning the insulation material outside the formwork, speeds up the construction efficiency, and increases the safety of formwork construction.

[0021] The interior of the aluminum alloy panel end rib 2 is evenly arranged with heating wires 7, and the surface of the heating wires 7 is sleeved with a number of fixing clamps 8, which are fixed to the inner wall of the aluminum alloy surface accommodating cavity 3. The aluminum alloy panel end rib 2 and the interior of the ribs 4 in the accommodating cavity are provided with wiring holes, and the heating wires 7 are arranged through the wiring holes. The heating wires 7 are firmly fixed by the fixing clamps 8, so that the heating wires 7 are evenly laid inside the aluminum alloy surface accommodating cavity 3 to achieve uniform heating. The input end of the heating wire 7 is connected to the output end surface of the heater 9, and the input end of the heater 9 is electrically connected to the output end of the controller 10 through a wire. The length of each heating wire 7 is 5 to 100 meters, the vertical height of the aluminum alloy template 1 is 2.6 meters, and the width is 0.4 meters. Each heating wire 7 passes through multiple aluminum alloy templates 1, and multiple aluminum alloy templates 1 are integrally connected. The body is assembled into a large integrated formwork. The heating wire 7 is insulated and waterproof to improve safety in use, and each heating wire 7 is connected to a controller 10 to control the heating temperature. One control box can control two heating wires 7. The heating wire 7 dissipates heat evenly, and the concrete protective layer with integrated insulation can also be well maintained. The concrete curing effect is good and the strength is improved quickly, which solves the problem of exterior wall insulation during winter construction. A temperature sensor 11 is installed on the inner wall of the aluminum alloy surface accommodating cavity 3. The temperature sensor 11 is arranged between the aluminum alloy formwork 1 and the insulation board 12. The output end of the temperature sensor 11 is electrically connected to the input end of the controller 10. The temperature sensor 11 is arranged between the aluminum alloy formwork 1 and the insulation board 12. The heating temperature is controlled by the temperature sensor 11 to reach a suitable temperature.

[0022] An insulation board 12 is fixed to the inner wall of the aluminum alloy panel end rib 2, and the insulation board 12 is arranged on the outside of the heating wire 7. The insulation board 12 is bonded to the inner wall of the aluminum alloy panel end rib 2 by strong glue, and the insulation board 12 completely fills the aluminum alloy surface accommodating cavity 3.

[0024] The system provides an external heat source, combined with internal heating measures and the concrete's own hydration heat, so that the concrete itself maintains a relatively high temperature, so that the concrete maintains a relatively high temperature in winter, which is conducive to the rapid growth of concrete strength, so that the concrete reaches the critical strength of freezing in a short time, so that the concrete will no longer be frozen. The entire system uses low-voltage power distribution, and even if the heating wire 7 is broken during transportation, there will be no electric shock accidents. The entire system is very safe.

The vertical height of the aluminum alloy template 1 is 2.6 meters and the width is 0.4 meters. Each heating wire passes through multiple aluminum alloy templates 1. Multiple aluminum alloy templates 1 are assembled into a large integrated template to avoid multiple joints in the heating wire 7. The heating wire 7 is insulated and waterproof to improve safety in use. Each heating wire 7 is connected to a controller 10 to control the heating temperature. One control box can control two heating wires 7. The heating wire 7 dissipates heat evenly. The insulation board 12 fills the entire accommodating cavity and fixes it with strong glue to play a role in insulation. At the same time, it also plays a protective role for the heating wire 7. A temperature sensor 11 is arranged between the aluminum alloy formwork 1 and the insulation board 12. The heating temperature is controlled by the temperature sensor 11. When each layer of formwork is constructed, the exterior wall formwork is hoisted as a whole to the upper layer.

After the concrete is poured, the heating wire 7 is energized for heating, and finally meets the winter construction and maintenance requirements of the exterior wall concrete. The integrated insulation concrete protective layer can also be well maintained, and the concrete maintenance effect is good, and the strength is improved quickly, which solves the problem of exterior wall insulation during winter construction, improves construction efficiency, reduces costs, improves safety, and saves resources, giving full play to the advantages of aluminum formwork winter construction and is suitable for promotion.
