BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a heat insulating composite plate cutter and a method of cutting a heat insulating composite plate using the same, and more particularly, to a heat insulating composite plate cutter having an organic foam panel and an inorganic foam panel bonded to one surface or both surfaces thereof, The present invention relates to a heat-insulating composite plate cutter capable of cutting a heat-insulating composite plate using the same.

The Green Building Support Act, which was enacted in 2017.01 to quantitatively evaluate the energy performance of buildings, was divided into five categories according to the degree of zero energy realization. The Zero Energy Building Certification System (Zero Certification System) has been established. The public sector is establishing zero energy mandates for all new buildings from 2020 and the private sector from 2025.

Zero Energy Building is a low-energy-use building that can save 75-95% in winter heating cost and 50% in summer heating cost by reducing heat loss by using advanced insulation method. It minimizes energy waste and reduces the use of fossil fuel It is said to be called 'green building'.

As an insulation construction method for reducing energy loss by blocking heat bridges, there is a method of inserting insulation, an interruption heat and an internal heat insulation depending on whether the insulation is applied to an outer wall, a middle wall, or an inner wall of a building such as a single- It is known that the outer insulation is the most effective for installing the insulation layer on the outer surface of the building.

As a typical example of the above-mentioned external adiabatic method, there is a so-called 'dry bit method'. This method uses a cement mortar adhesive to which a chemical agent is added to the surface of a inorganic structural material such as a concrete wall or a slab, A foamed polystyrene panel such as "pink", a glass fiber mesh is attached on the panel, an adhesive mortar added with the above chemical agent is applied, and the surface is treated with various chemical finishes.

However, since the foamed polystyrene panel is an organic type, the adhesive force to the surface of the inorganic structural material such as the concrete wall and the slab is weak, so that it is inevitable to use a large amount of the organic chemical adhesive and is vulnerable to fire due to the use of the chemical finishing material. There is a problem that the external heat insulating structure tends to be torn off by an external force such as a typhoon or the like in case of a bad construction.

In order to solve such a problem, the present applicant has proposed an organic (resin) foam board as disclosed in Korean Patent Registration No. 10-1211383 (Registered on December 26, 2012). 40 to 65% by weight of inorganic filler containing talc, zinc oxide, and 35 to 60% by weight of vinyl chloride resin, which are laminated on the surface of the above-mentioned organic foamed sheet material. The average particle diameter of discrete independent cells An inorganic foam plate having a thickness of 0.3 to 3.0 mm; And an adhesive layer between the organic foam board and the inorganic foam board: the thickness of the inorganic foam board is 3 to 50 mm, the thickness of the inorganic foam board: organic foam board is 1: 1 to 20, The inorganic filler is composed of 25 to 35% by weight of calcium carbonate, 10 to 20% by weight of talc, and 5 to 10% by weight of zinc oxide, and the organic foamed sheet material is a polystyrene foam, a polyurethane Or a polyethylene foam, and has been commercially marketed.

As shown in FIG. 3 and the like, the above-mentioned heat-insulating composite plate is produced by joining two sheets of foamed polystyrene sheet having a thickness of, for example, 110 mm, and attaching calcium carbonate-based inorganic foamed plates each having a thickness of about 5 to 15 mm on the upper and lower surfaces thereof Lt; / RTI >

The above-mentioned expanded polystyrene plate is a foamed bead polystyrene panel such as 'Styrofoam' or 'isoprene', and the dimensions thereof are usually 110 × 900 × 1800 mm, , Or two to three sheets or more are bonded and used.

The heat insulating composite plate is formed by placing the above calcium carbonate-based inorganic foamed sheet material on the upper or lower surface of the at least one foamed polystyrene plate and between the upper and lower surfaces of the foamed polystyrene sheet, and they are press bonded using an adhesive.

In the zero-energy building for minimizing the energy waste due to the reduction of heat loss due to the complete thermal bridge interception, the dimension accuracy and the corner angle accuracy of the above-mentioned heat insulation composite plate are very important because if the dimension and the corner angle accuracy are low, This is because the thermal bridge phenomenon occurs through the gap between the composite sheets.

Therefore, the above-mentioned heat insulating composite sheet needs to be cut to a predetermined reference size so as to have high dimensional accuracy, and such high dimensional accuracy is more strictly required in the longitudinal direction (i.e., the height direction) than in the width direction.

In addition, it is necessary to use a plurality of heat insulation composite sheets having a predetermined reference size at the time of outer heat insulation of the zero energy structure, and to use the heat insulation composite sheets with a size that exactly matches the dimensions or area of the remaining heat insulation composite sheets.

The applicant of the present invention has previously proposed a method of manufacturing a heat insulation composite plate having a predetermined standardized size and high dimensional accuracy through the longitudinal cutting of the heat insulation composite plate and a method of manufacturing a heat insulation composite plate using the above- 3 and 4 have been used for the production of a heat-insulating composite plate having dimensions, area and shape that exactly fit in the shape of the insert.

Each of the heat insulation composite plates 100 in the illustrated example is formed by stacking three pieces of the heat insulation composite plate 100 in the form of a lamination in which the inorganic foamed plates 102 are laminated on the upper and lower surfaces of two pieces of the organic foamed plates 101, The length of the heat insulating composite plate 100 located on the uppermost layer is cut to a predetermined length, and after cutting lines are displayed using a ruler and a pen, a plurality of pin holes The two metal brackets 1 'having a "U" -shaped shape in which the metal brackets 1a' are perforated in the longitudinal direction at predetermined intervals are positioned so as to face each other, and one end of each of the metal brackets 1 ' The plurality of fixing pins 2 'whose heads are formed in the form of a loop 2a' are inserted into the organic foamed sheet material 101 through the pin holes 1a 'of the above-described steel bracket 1' , And then the hot wire 3a 'of the hot wire cutter 3' (1 ') and at the same time cutting downward from above along the one end of the.

However, in the conventional cutting method of the present applicant as described above, there is a fear that the cutting line display operation using the ruler and the pen may be inaccurate, and in addition, in the organic foamed sheet material in which the fixing pin 2 ' There is a possibility that the heat insulating composite plate members 100 may not be precisely laminated so that the trimmed corner angle may not be maintained at an angle of 90 degrees exactly.

As a result, there is a problem that the above-mentioned conventional cutting method is inferior in work efficiency and there is a possibility of a difference in accuracy depending on the skill of the worker.
