Description

[Detailed description of the invention]

[Industrial Field of Application] The present invention relates to a heat insulating block structure. More specifically, the present invention relates to a heat insulating block structure with excellent workability and walkability. [Prior Art] and [Problems to be Solved by the Invention] The living environment in Japan has come to require buildings to be cool in the summer and warm in the winter, making buildings more comfortable for living. The current situation is that awareness of insulating building materials is increasing day by day. In buildings such as buildings, schools, and factories, for example, the rooftops are also used for walking, and in addition to insulation, these areas are required to have good walkability, and on top of that, there is a shortage of skilled craftsmen. In these days, it is also important to have excellent workability. The object of the present invention is to provide a block structure that not only has excellent heat insulation properties but also has excellent construction and walkability. [Means for Solving the Problems] Accordingly, the present invention relates to a rooftop insulation block structure, and the rooftop insulation block structure is provided with a cutout portion having a shape corresponding to the leg portion of the block described later at the corner portion. An adhesive pad made of an adhesive-coated foam sheet is inserted into a notch hole formed by a foamed polystyrene board with grooves diagonally diagonally between the notches on the construction surface. It has a structure in which the legs of a block having legs at the corners on the back side and protrusions that can fit into the grooves on the diagonal line between the legs are placed and glued on the adhesive pad. ing. Figure 1 of the drawings is a perspective view of one embodiment of the heat insulating block from the front side, and Figure 2 is a perspective view of the back side of the block with the Styrofoam board and the adhesive pads at the three corners omitted; FIG. 3 is a perspective view showing each element of the heat insulation block separately. That is, the heat insulating block basically consists of a block 1, a foamed polystyrene board 4, and an adhesive pad 9. At the corner of the back side of block 1, there are legs 2,
2', 2'', 2 are integrally provided.On the diagonal lines 2-2'' and 2'-2 between these legs,
At least one of them, preferably both, are provided with protrusions 3, 3' having a semicircular cross section as fitting and reinforcing ribs. Further, the foamed polystyrene board 4 has notches 12, 12', 12'', 12 having shapes corresponding to the shapes of the block legs 2, 2', 2'', 2.
are provided, and on the surface side thereof, at least one of the diagonal lines 12-12'' and 12'-12 of the notch portion is provided with grooves 5, which can fit into the protrusions 3, 3'.
5' is provided, so that when the block 1 is stacked on the foamed polystyrene plate 4, the protrusions and grooves are fitted into each other so that the block 1 is properly housed. Furthermore, the adhesive patch used is, for example, a foamed plastic sheet having a thickness of about 10 mm for a block leg height of 40 mm, with adhesive applied to both sides by means such as impregnation. The method for constructing a heat insulating block according to the present invention will be specifically explained with reference to the drawings in FIGS. 1 to 3 and the drawing in FIG. 4, which shows the block construction state as a side view. (1) A cylindrical concrete 7 is placed on top of the waterproof layer 6 on the construction surface, and the mortar 8 on top is used to adjust the water gradient, horizontality, etc. (2) Spread the polystyrene foam boards 4 over the entire construction surface, temporarily fixing them with adhesive if necessary. Note that the styrene foam board may be formed by integrally molding, for example, nine styrene foam boards, three each in the vertical and horizontal directions, and joined at 13 of the sides. (3) Into the holes formed by the notches of the spread polystyrene plates 4, insert the adhesive pads 9, which have a structure in which, for example, a butyl rubber adhesive or the like is impregnated and coated on both sides of a foamed polyethylene sheet. (4) Lightly place the leg part 2 of the block so that its bottom surface touches 1/4 area of the rectangular adhesive pad 9 (see Figures 1 and 2), and place about several dozen blocks 1 on it. Once placed, pressurize the block by walking on it to fix it. (5) A suitable sealing material such as joint mortar is embedded in the joints 10 between the sides of the blocks, and the formed joints 11 formed by cornering the blocks are filled with a suitable sealing material such as joint mortar.
shall be covered with cement mortar or urethane resin mortar as necessary. The blocks to be constructed can be of any shape as long as they can be laid out, such as squares or hexagons.
The shape of the bottom surface of the leg can also be 1/4 or 1/3 depending on the shape of the adhesive pad on which it is placed, such as a polygon or a circle. Furthermore, the fit formed by the convex stripes on the back side of the block and the grooves on the front side of the Styrofoam plate is
As long as these are structured to fit and engage with each other, they can be formed from protrusions and grooves with any cross-sectional shape, and from the viewpoint of reinforcing effect, it is preferable that the length spans the entire length of the diagonal line. Of course,
It may be part of that length. [Effects of the Invention] The heat insulating block structure according to the present invention provides the following effects. (1) Construction can be performed easily and accurately. That is, during construction, first the Styrofoam boards are laid down, but since the Styrofoam boards have a certain shape that allows them to be laid, generally rectangular, their positioning can be done easily and accurately, and the blocks can be placed evenly on both sides. By utilizing the strips and corner holes, it can be easily mounted on a Styrofoam board. (2) The insulation properties are significantly improved. By enclosing Styrofoam on the back side of the block, the heat conduction resistance is approximately 10 times higher than that of a simple hollow layer without a Styrofoam layer, and the heat insulation properties are significantly improved. As a result, the ceiling on the top floor is no longer necessary, resulting in cost savings. [Thermal Insulation Performance Test] The test was conducted at the Building Materials Testing Center of Japan in accordance with JIS A-1420 (Testing Method for Insulating Properties of Residential Insulating Materials) using the measurement principle of the calibrated thermal box method. The test specimen was constructed in accordance with on-site construction assuming a virtual rooftop slab at the opening of the heating box, the heat flow direction was upward assuming heating, and the test conditions were three temperature conditions. The measurement results are shown in Tables 1 and 2 below. (Measurement positions: points A, B, and C in Figure 1) A-1: Adhesive sheet - slab surface A-2: Block leg - adhesion sheet surface A-3: Top surface of block B-1: Styrofoam board - Slab surface B-2: Block-Styrene foam board surface (rib intersection) B-3: Block top surface C-1: Styrofoam board-Slab surface C-2: Block-Styrene foam board surface C-3: Block top surface

(3) Good walkability. The rooftops of buildings, schools, factories, and other buildings are often used for walking, and are required to have good walkability.However, in the insulation block structure according to the present invention, the blocks are directly attached to the construction surface. Since it is placed on a styrofoam board instead of being placed on a table, its cushioning properties cushion the impact when walking, and it exhibits good walking performance. (4) Since the block is only fixed at its legs by adhesive parts, the block can be easily removed and repaired or replaced.
