[0052]The invention uses foamed aluminum as an intermediate material, and cleverly applies it to the field of building formwork 1. Among them, foamed aluminum is formed by adding additives to pure aluminum or aluminum alloy through a foaming process. It has both metal and bubble characteristics. It has the characteristics of low density, high impact absorption, high temperature resistance, and good heat preservation performance. , So as to improve the overall support strength, foam aluminum has excellent physical, chemical and mechanical properties, as well as recyclability. Because of its low thermal conductivity, it also has the advantages of light weight, high specific rigidity and non-combustibility. It can be used as heat insulation , Heat preservation, cold preservation materials, etc., high damping and shock absorption performance and impact energy absorption rate, non-combustion, good heat resistance and easy processing characteristics, the density is 0.1 to 0.4 times that of metal aluminum, and its bending specific stiffness is 1.5 times that of steel, damping performance is 5-10 times that of metal aluminum, and when 50% of the foam aluminum with a porosity of 84% is deformed, it can absorb 2.5MJ/cm3The above energy, good corrosion resistance, good weather resistance, low moisture absorption, no aging, non-toxicity, convenient cutting, drilling, and cementing, can be bent into the required shape after molding, can be surface treated with organic or inorganic paint, and can be double-sided The skin constitutes a large-size lightweight panel. However, there are also some shortcomings. For example, the foamed aluminum plate is easy to sag and deform when it directly bears gravity. It cannot be directly used as a building template 1 with a large bearing capacity without the assistance of other technical means.
[0053]When the foamed aluminum building dismantling-free formwork of the present invention is used, it is basically the same as a conventional building dismantling-free formwork, but it is more convenient and quicker. During construction, install the aluminum foam building non-demolition formwork through steel hoop 3 connectors and formwork brackets. When the concrete 6 building body is poured to meet the strength requirements, remove the steel hoop 3 connectors and formwork brackets. The formwork is tightly integrated with the main body of the concrete 6 building, and there is no need to disassemble the aluminum foam building without dismantling formwork, which does not fall off safely; and the quality of the foam aluminum building free dismantling formwork is relatively heavy, and it basically does not cause stress fatigue on the concrete 6 building main body. Hidden dangers. Moreover, the foam aluminum plate has the characteristics of air bubbles, it is easy to dig a wire slot inside the building formwork 1, and it is also very convenient to embed pipeline lines.
[0054]In the above description, it should be noted that the filling part of the foamed aluminum 2 shown in the drawings is not the actual shape and structure of the foamed aluminum 2. This is because the surface of the foamed aluminum is irregular and cannot be represented by a specific structure. to.
