Description

  The present invention relates to a heat insulating and waterproofing structure provided with a heat insulating material and a waterproofing material installed along a floor and a wall of a casing in a heat storage tank or the like.

  Thermal storage tanks such as cold water tanks, warm water tanks, cold water tanks and ice thermal storage tanks installed in the basement of a building are not only sources of heat medium in the original air conditioning facilities, but in recent years Its utility as a source of water is being reaffirmed.

  The conventional heat insulating and waterproofing structure forming the inner circumferential surface of such a heat storage tank is a flat heat insulating material 11 on the surfaces of the floor 10a and the wall 10b of the concrete frame in a basement of a building or the like as shown in FIG. Are attached by a plastic anchor 12 and a waterproof layer 13 is formed by spraying an ultra-fast curing urethane waterproofing material on the surface of the heat insulating material 11.

  Moreover, in the following patent document 1, the heat insulation waterproof structure in the thermal storage tank which formed the waterproof layer by extending a waterproof sheet along the surface of the heat insulating material 11 is disclosed.

By the way, in the above-mentioned heat storage tank, in the case of 3 m of water depth, for example, while the water pressure of 3 t / m ² is always received at the bottom, the heat insulating material 11 is largely deformed due to low rigidity. A tensile force is generated in the waterproof layer 13 stretched on the surface 11, and a local elongation occurs in an inner corner where the heat insulating material 11 intersects at right angles, which is one of the causes of the water leakage.

  Moreover, in the waterproof layer 13 by spray construction in particular, it is difficult to apply a waterproof material to the above-mentioned inward corner portion with a certain thickness, and there is a property that a pin hole is easily made.

  Therefore, in the above conventional heat insulating and waterproofing structure, as shown in FIG. 13, after the heat insulating material 11 is applied, the triangular surface is formed on the inward corner portion in order to solve the waterproofing problem caused by the inward corner portion. By arranging the wood 14 and applying a waterproof material from above, it is prevented that a 90 ° corner portion is formed at the intersection in the heat insulating material 11. At this time, as shown in FIG. 14, an R-face tree 15 may be used in which the surface in the heat storage tank is formed by a concave surface.

  However, even in the case where such face trees 14 and 15 are disposed, there is a problem that corner portions are generated at the end portions 14a and 15a of the face trees 14 and 15 to cause water leakage.

  Further, due to the construction error of the floor 10a and the wall 10b, unless the angle between the heat insulators 11 attached to the floor 10a and the wall 10b is 90 °, the end portions 14a and 15a of the above-mentioned plane trees 14, 15 and There is also a problem that a gap is generated between the heat insulating material 11 and, similarly, a pinhole is easily made at the time of construction of the waterproof material.

  In the invention according to claim 1 or 2, a corner heat insulating material having a shape in which a heat insulating material positioned in a conventional inward corner portion and a plane wood are integrated is disposed at an inner corner portion of the heat insulating material orthogonal to each other. In addition, since the inner circumferential surface of the corner heat insulating material is formed by a concave surface continuous with the surface of the adjacent heat insulating material, the cause of water leakage as in the case of using a conventional face wood at the inner corner portion Corners do not occur.

  And since the said corner heat insulating material is a thing of the shape which the heat insulating material located in the conventional corner part and the surface wood were united, the angle which the heat insulating material by the side of a wall and the heat insulating material of a floor side make. Even if the angle is not exactly 90.degree., There is no gap that is likely to cause corners or pin holes that cause water leakage.

  As a result, it becomes possible to obtain high waterproofness, and in particular, as in the invention according to claim 2, the ultrafast curing urethane waterproofing material is spray-applied to the surface of the heat insulating material and the inner peripheral surface of the corner heat insulating material. Therefore, when applied to a structure forming a waterproofing layer, it becomes possible to easily apply a waterproofing material with a certain thickness, and thus it is possible to prevent the occurrence of the above-mentioned pinholes. An effect is obtained.

  1 to 12 show the main part of an embodiment in which the heat insulation and waterproof structure according to the present invention is applied to a heat storage tank, and the heat insulation and waterproof structure in this heat storage tank is a floor 1a of a concrete frame of a basement of a building and A plurality of rectangular plate-shaped heat insulators 2 are attached to the wall 1 b by the plastic anchor 3, and conductive films (not shown) are attached to the required places on the surfaces of the heat insulators 2, 5, 6. A waterproof layer 4 composed of a spray-applied super rapid curing urethane waterproof material is formed on the surfaces of the heat insulators 2, 5, 6 and the conductive film. Incidentally, the said conductive film is for performing thickness measurement of the waterproof layer 4, and detection of a pinhole, as disclosed also in the said patent document 2. FIG.

  Here, in the heat storage tank to be a target of the present embodiment, as shown in FIG. 10, a part of the foundation 1c protrudes from the corner of the floor 1a and the wall 1b, thereby making the heat insulation waterproof structure , The heat insulating material 2 in a tank is formed with the entering corner part and the projecting corner part. And the 1st corner heat insulating material (corner heat insulating material) 5 is arrange | positioned at the intersection of the heat insulating material 2 used as an inside corner part.

  The first corner heat insulating material 5 has an outer peripheral surface 5a in contact with the floor 1a or the wall 1b, and a width dimension equal to the thickness dimension of the heat insulating material 2. It is a rod-like member defined between the contact surface 5b and the inner peripheral surface 5c which is between the contact surfaces 5b and which becomes the inside corner, and is made of the same material as the heat insulating material 2.

  The inner peripheral surface 5c of the first corner heat insulating material 5 is, as shown in FIG. 2, a concave surface continuous with the surface of the adjacent heat insulating material 2, more specifically, the heat insulating material 2 in the present embodiment. The surface is formed by a quarter circumferential surface that is tangential.

  On the other hand, the 2nd corner heat insulating material 6 is arrange | positioned at the intersection of the heat insulating material 2 used as a projecting corner part. Similarly, the second corner heat insulating material 6 is made of the same material as the heat insulating material 2, and is a rod-like member obtained by equally dividing a circular cylinder whose radius is the thickness dimension of the heat insulating material 2 into 1/4 circumferences. . As a result, the second corner heat insulating material 6 is provided with an abutting surface 6a which abuts the end face of the heat insulating material 2 with the right angle interposed therebetween, and a protruding corner portion by a 1⁄4 circumferential surface between these abutting surfaces 6a. It is defined by the outer peripheral surface 6b to be formed.

  As described above, in this heat insulating and waterproofing structure, the inner and outer corners of the heat insulating material 2 are formed by the inner peripheral surface 5 c of the first corner heat insulating material 5 and the outer peripheral surface 6 b of the second corner heat insulating material 6. It is formed of a concave curved surface or a convex curved surface having a cross-sectional arc shape continuous from the surface.

  Furthermore, in this heat insulation and waterproofing structure, as shown in FIG. 1, the corner A to which the three first corner heat insulators 5 are connected and the corner to which the three second corner heat insulators 6 are connected The corners A, B, and C are smoothly recessed at the corner B and at the corner C where the two first corner heat insulators 5 and one second corner heat insulator 6 are connected. It is processed to be a curved surface or a convex surface.

  That is, at the corner A, as shown in FIGS. 3 to 5, first ends of the first two corner heat insulators 5 disposed in the horizontal direction are disposed in the vertical direction. An abutting surface 7a formed in a width dimension equal to the abutting surface 5b of the corner heat insulating material 5 and connected to the abutting surface 5b, and a first corner insulating material 5 in the vertical direction projecting from the abutting surface 7a. An outer peripheral surface 7b in contact with the inner peripheral surface 5c and a front end surface 7c in contact with the adjacent first corner heat insulators 5 in the horizontal direction are formed.

  As a result, a substantially spherical concave surface is formed by the inner peripheral surface 5 c at the end of the three first corner heat insulators 5 at the corner where the three first corner heat insulators 5 are connected. It is done.

  The end portions of the two first corner heat insulating materials 5 disposed in the horizontal direction are processed into the above shape by, for example, an NC processing machine. Further, at the locations where the conductive film is attached to the inner circumferential surface 5c of the first corner heat insulating material 5, the conductive film is applied to the inner circumferential surface 5c of the first corner heat insulating material 5 before the NC processing is performed in advance. By carrying out the above-mentioned NC processing by pasting, it is possible to form the above-mentioned concave surface having a substantially spherical shape without causing wrinkles or unevenness on the above-mentioned conductive film.

  Further, at the corner B to which the three second corner heat insulators 6 are connected, as shown in FIGS. 6 and 7, the two second corner heat insulators 6 arranged in the horizontal direction The end portion is cut at an angle of 45 degrees with respect to the axis to form an abutting surface 8 with which the adjacent second corner heat insulating materials 6 abut.

  Thereby, in the connection part of the three 2nd corner heat insulating materials 6, the smooth convex curved surface is formed. In the place where the conductive film is attached to the outer peripheral surface 6b of the second corner heat insulating material 6, the conductive film is similarly formed on the outer peripheral surface 6b of the second corner heat insulating material 6 before the NC processing is performed in advance. By carrying out the above-mentioned NC processing by pasting, it is possible to form a continuous convex curved surface without generating wrinkles and unevenness on the above-mentioned conductive film.

  In addition, after connecting the three second corner heat insulators 6, a conductive film is attached to the outer peripheral surface 6b, and at this time, a map paper is attached to the globe at the end of the conductive film. The same notch shape may be processed and pasted so as to form the convex curved surface on the connection portion.

  Furthermore, as shown in FIGS. 8 and 9, at the corner C where two first corner heat insulators 5 and one second corner heat insulator 6 are connected, two first ones are provided. Since the outer peripheral surface 6b of one second corner heat insulating material 6 is a convex curved surface while the connecting portion of the corner heat insulating material 5 is a concave curved surface by the inner peripheral surface 5c, the second corner heat insulating material A convex chamfered portion 9 is formed at an end portion of the first corner heat insulating material 5 adjacent to the connection end portion 6.

Next, based on FIGS. 10-12, the construction procedure of the heat insulation waterproof structure in the thermal storage tank shown to FIGS. 1-9 is demonstrated roughly.
First, as shown in FIG. 11, the concrete box shown in FIG. 10 is formed with an inward corner at the intersection between the floor 1a and the wall 1b and at the intersection between the floor 1a or the wall 1b and the foundation 1c. Attach the corner insulation 5 of.

  Next, as shown in FIG. 12, the heat insulating plates 2 are attached to the three surfaces of the foundation 1c, and the second corner heat insulating material 6 is inserted and attached between the ends of the adjacent heat insulating plates 2. And the heat insulating material 2 is attached to the floor 1a and the wall 1b of the concrete frame. At this time, as described above, the conductive film is attached to the inner peripheral surface 5c and the outer peripheral surface 6b of the heat insulating material 2, the first and second corner heat insulating materials 5, 6 in advance at the place where the conductive film is to be adjusted. Set up. Alternatively, after the heat insulating material 2 and the first and second corner heat insulating materials 5 and 6 are attached, the conductive film may be attached by on-site application.

  Then, a super-fast curing urethane waterproofing material is spray-applied to the surface of the heat insulating material 2 and the first and second corner heat insulating materials 5 and 6 or the surface of the conductive film attached to the surface to form a waterproof layer. By forming 4, the construction of the heat insulation and waterproof structure shown in FIG. 1 is completed.

  As described above, according to the heat insulating and waterproofing structure having the above-described configuration, the heat insulating material located in the conventional inside corner portion and the inside corner portion of the floor 1a and the wall 1b and the inside corner portion of the orthogonal wall 1b While arranging the first corner heat insulating material 5 integrated with the face wood, the inner peripheral surface 5c of the first corner heat insulating material 5 forming the inside corner portion is continuous with the surface of the adjacent heat insulating material 2. Since the concave surface of the 1⁄4 circular arc is used, there is no occurrence of a corner as in the case of using a conventional face wood at the inside corner.

  In addition, since the first corner heat insulating material 5 has a shape in which the conventional heat insulating material located at the corner and the face wood are integrated, the heat insulating material 2 on the floor 1 a side and the wall 1 b side Even in the case where the angle between the heat insulator 2 and the heat insulator 2 is not exactly 90 °, there is no gap where pin holes occur.

  Further, as in the present embodiment, when the heat storage tank has a projection such as the foundation 1c, the second corner heat insulating material 6 is disposed between the heat insulating materials 2 attached to the wall or floor of the foundation 1c. In addition, since the outer peripheral surface to be the protruding corner portion of the second corner heat insulating material 6 is formed by a convex curved surface of 1⁄4 circumference, the corner portion which causes water leakage also in the protruding corner portion It is possible to prevent the formation of gaps that are likely to cause pin-holes.

  As a result, when the waterproof layer 4 is formed by spray-coating the ultrafast curing urethane waterproofing material on the inner peripheral surface 5 c and the outer peripheral surface 6 b of the heat insulating material 2 and the first and second corner heat insulating materials 5 and 6. It is possible to easily apply a waterproofing material with a certain thickness, and thus high waterproofness can be obtained.

  In the above embodiment, the waterproof layer is formed by spraying a super-fast curing urethane waterproofing material on the surface of the heat insulating material 2 and the inner peripheral surface 5c and the outer peripheral surface 6b of the first and second corner heat insulating materials 5 and 6. Although only the case of forming 4 has been described, the present invention is not limited to this, and the same applies to the case where a waterproof sheet is attached to the surface of the heat insulating material 2 or the like to form a waterproof layer. You can get the effect of

  Moreover, in the said embodiment, the case where the conductive film for performing thickness measurement of the waterproof layer 4 and detection of a pinhole was stuck was demonstrated in the required location of the surface of the heat insulating materials 2, 5, 6 However, it can apply similarly, when not applying the above-mentioned conductive film.
