Description

Thermal insulation board for building

This creation is related to insulation materials, especially regarding a heat shield for buildings.

At present, the insulation materials used in the top floor of buildings are generally based on styrofoam (polystyrene) plates. The advantage of this type of plate is that the thermal conductivity is low, which means that the heat insulation function is good, but the disadvantage is that the hardness is not good. After a period of use, it will be bent and deformed by the extrusion of the reinforced concrete (RC) layer laid thereon. In order to solve this problem, some operators put a large number of through holes on the styrofoam plate for the filling of part of the reinforced concrete (RC) layer to reduce the deformation phenomenon, but in this way, the filling The columnar concrete in each through hole of the sheet will form a thermal bridge, which will increase the thermal conductivity, in other words, the heat insulating function will be reduced. Experiments have shown that the heat transfer coefficient after laying in this way is about 4 times higher than when it is not laid. In addition, it is necessary to mention that after the insulation board is completed, a linear heat bridge will be formed at the intersection of the adjacent insulation boards, and the overall thermal conductivity will also increase.

The main purpose of this creation is to provide a heat shield for use in buildings that does not increase the heat transfer coefficient due to laying or construction.

Another object of the present invention is to provide a heat shield for use in a building that does not produce a linear thermal bridge.

A further objective of the present invention is to provide an insulation for use in buildings. The board, which is more compatible with the reinforced concrete (RC) layer than the conventional heat insulating sheet.

Another object of the present invention is to provide a heat shield for use in a building that can be positioned and supported as a reinforcing bar when laying a reinforced concrete (RC) layer.

The reason is that, in order to achieve the foregoing, the heat shield disclosed in the present invention comprises a rectangular body and an interface layer. The system is made of a polyurethane (PU) rigid foam material having a top surface, a bottom surface and two pairs of opposite sides therebetween. The interface layer is attached to the top surface of the body for increasing the adhesion of the body to the reinforced concrete (RC) layer of the building. In addition, each of the opposite sides of the body is respectively provided with a complementary step surface, so that when laying, the steps of the adjacent two insulating panels can be overlapped with each other to form a curved shape. Lines are used to reduce the thermal bridge effect.

In addition to the foregoing features, the heat shield disclosed in the present invention may form a plurality of grooves distributed in a row at a predetermined interval from the top surface of the body. In this way, the protruding surface between the adjacent grooves can be used for supporting the reinforcing bars when the reinforced concrete layer is laid, and the grooves themselves can be filled into the grooves by the concrete, so that it is easier to construct on the one hand, and the other is easier to construct. In this respect, the adhesion of the reinforced concrete (RC) layer to the insulation board can be increased.

The present invention will be further described with reference to a number of embodiments and drawings, wherein: the first drawing is a perspective view of the first preferred embodiment of the creation; the second drawing is an exploded perspective view of the embodiment shown in the first figure; 3 is a cross-sectional view in the direction of the first FIG. 3-3; the fourth drawing is a schematic view of the first embodiment shown in the first embodiment; the fifth drawing is a perspective view of the second preferred embodiment of the present invention; 6 is a cross-sectional view in the direction of the sixth FIG. 6-6; and the seventh figure is a schematic view of the embodiment shown in the fifth figure in actual construction.

First, please refer to the first to fourth figures, wherein the figure shown in Figure 10 is the insulation board implemented according to the concept of the creation. The heat shield 10 includes a rectangular body 12 and an interface layer 14. The rectangular body 12 is molded from a polyurethane (PU) rigid foam material having a top surface 122, a bottom surface 124 and two pairs of opposing sides 126, 128, 130, 132 therebetween. The interface layer 14 is attached to the top surface 122 of the body 12 for subsequent reinforced concrete (RC) layers (not shown) of the building. The interface layer 14 can be generally made of a cloth material, which is a non-woven fabric in the embodiment. At the time of manufacture, the interface layer 14 is attached to the cavity surface of the mold of the molded body 12, whereby the body 12 can be molded. At the same time, its top surface 122 is attached.

The opposite sides 126, 128 of the body 12 are respectively provided with complementary first step faces 134 and second step faces 136. The other opposite sides 130, 132 of the body 12 are respectively provided with complementary third step faces 138 and fourth step faces 140.

During construction, most of the insulation panels 10 are laid on the top floor of the building, and then the reinforced concrete (RC) layer is filled on the surface 142 of the interface layer 14. Since these construction methods are conventional techniques, this is It will not be detailed. However, it must be mentioned that the heat insulating panel 10 has a body 12 molded by a polyurethane (PU) rigid foaming material, and can withstand a large pressure compared to the styrofoam heat insulating panel, and does not have to reserve a majority. The through holes are used to fill the concrete, thereby also reducing the thermal bridge phenomenon. Furthermore, each of the heat insulation panels 10 is separated from each adjacent insulation panel by each step The steps of 10 are overlapped with each other. As shown in the fourth figure, since the steps are complementary, they will form a bent intersection 20 after overlapping each other. Thus, the thermal bridge effect can be reduced. lowest. According to the CNS7774 test method, the thermal conductivity of the 5mm thick insulation board 10 is about 0.0276 W/m. K.

Next, please refer to the fifth to seventh figures, wherein the figure 30 is another heat insulation board implemented according to the creative concept. The heat shield 30 also includes a rectangular body 32 and an interface layer 34. The heat shield 30 is different from the heat shield 10 in that the top surface 302 is provided with a plurality of first recesses 36 extending along a length thereof and spaced apart from each other by a predetermined interval, and a plurality of portions extending in a width direction thereof and spaced apart from each other by a predetermined interval Two grooves 38. With this design, when filling the reinforced concrete (RC) layer, the reinforcing bars 40 can be placed on the top surface 302 of each adjacent groove, as shown in the sixth figure, while the concrete 42 is filled in each In the groove, on the one hand, it is easier to apply, and on the other hand, the adhesion of the reinforced concrete (RC) layer to the heat shield 30 can be increased.
