[63] FIG. 8 is a perspective view of a constructive light weight heat insulation block according to another embodiment of the present invention. FIG. 9 is a cross-sectional view of the constructive light weight heat insulation block shown in FIG. 8 taken along a line A-A. FIG. 10 is a partial perspective view of the constructive light weight heat insulation block shown in FIG. 8. FIG. 11 is a state view of the constructive light weight heat insulation block shown in FIG. 8. [64] Referring to FIG. 8 through 11, the heat insulation block 1 that is stacked in interior and exterior walls of a building comprises a coupling projection 11 formed on the top surface thereof so that a recess is not generated when a plurality of heat insulation blocks are stacked and a coupling groove 12 formed on the bottom surface thereof and WO 2009/044969 PCT/KR2008/001256 corresponding to the coupling projection 11, second-stepped groove portions 3 that are second-step curved from an edge of a storing portion 2 of the heat insulation block 1 in the front and rear surfaces of the heat insulation block 1, a heat proof board 4 formed of one selected from a plaster board, a rock wool, and a glass cotton mat, and inserted into an interior groove portion 31 disposed in the second-step groove portion 3 in an inner direction, and a finishing board 5 formed of one selected from a stone material, steel fiber reinforcement concrete, a dryvit, PVC, and metal and inserted into an exterior groove portion 32 disposed in the second-step groove portion 3 in an exterior direction and having a grouting groove 321 formed in one side thereof. [65] The heat insulation block 1 is formed of a light weight bubbling synthetic resin, i.e., bubbling polyethylene, finishes interior and exterior walls of the building, reduces material expense, simplifies an operation process, and reduces a construction time. [66] The distance between the second-step groove portion 3 formed in the heat insulation block 1 and the interior groove portion 31 may be longer than that between the second step groove portion 3 and the exterior groove portion 32. [67] The heat proof board 4 inserted into the interior groove portion 31 is a light weight heat proof material and is good at water proof, sound proof, and heating efficiency. Meanwhile, since the plaster board, the rock wool, and the glass cotton mat are widely known, the present invention does not repeat the specific characteristics thereof. [68] The characteristics of the stone material, the steel fiber reinforcement concrete, and the dryvit other than the PVC and metal that are generally used as the finishing materials will now be briefly described. [69] Although the stone material is a relatively expensive material used as an exterior wall material, the stone material is frequently used as an art decoration component owing to a firm durability and unprocessed irregular texture of the exterior wall. Although the stone material is used for the overall external wall, the stone wall can be partially mixed with another material as a substitute for a reduction in the construction costs and an individual presentation. [70] The steel fiber reinforcement concrete irregularly arrange single phase steel fiber instead of traditional type steel and scatters the steel fiber in concrete so as to prevent a crack and increase durability. Since this panel is mixed with the steel fiber and has enhanced durability, the panel is not contracted due to rain, wind, and heat, and is good at proportion intensity and compression intensity. [71] The dryvit is a material having various textures that has a good durability and no color change by mixing acryl resin having a purity of 100% and a chemical material and special quartz sand. If the dryvit is used to finish the exterior wall, an auxiliary heat proof and water proof construction are not necessary and the wall structure is light weight, thereby reducing structuring costs. The dryvit has various textures and colors, WO 2009/044969 PCT/KR2008/001256 prevents a crack owing to its condensation prevention and ordinary temperature and moisture effect, and maximizes water proof and durability. [72] The heat proof board 4 and the finishing board 5 of the present invention may be selected from a board having the corresponding performance necessary for a harmony with the structure of the building. [73] A process of assembling the constructive light weight heat insulation block of the present invention will now be described. [74] The heat proof board 4 is inserted into the interior groove portion 31 disposed in the second-step groove portion 3 of the heat insulation block 1. Thereafter, the finishing board 5 is inserted into the exterior groove portion 32. [75] An inorganic adhesive agent is grouted in the grouting groove 321 formed in one side of the finishing board 5 so that the finishing board 5 is firmly fixed to the heat in sulation block 1. A plurality of heat insulation blocks 1 in which the heat proof board 4 and the finishing board 5 are sequentially fixed to the front and rear surfaces thereof are stacked by locating the coupling groove 12 of the heat insulation block 1 in the coupling projection 11 of the basic heat insulation block 1.
