Description

[Technical field]

[0001] The present invention relates to an external insulation structure for a building. [Background technology]

[0002] In construction work, there are two methods for insulating rooftops: internal insulation and external insulation, and external insulation is generally used. Patent Document 1 describes an external insulation method for rooftops, in which a waterproof layer and an insulating layer are provided on the outside (above) of a concrete slab. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5555364 Summary of the Invention [Problem to be solved by the invention]

[0004] In external roof insulation construction methods, the insulation lines can be partially interrupted due to the foundations of rooftop equipment, etc., and in the areas where the insulation lines are missing, insulation material such as urethane foam is sprayed on from the inside of the room to reinforce the insulation.

[0005] However, if the space below the roof is one that requires high levels of cleanliness, such as a clean room, dust-generating materials such as urethane foam cannot be used as insulation reinforcement on the indoor side. Therefore, a covering plate or the like is required to hide the urethane foam, which lengthens the construction period.

[0006] The present invention has been made in consideration of the above problems, and has an object to provide an external insulation structure etc. that can easily complete external insulation. [Means for solving the problem]

[0007] The first invention for solving the above-mentioned problems is an external insulation structure comprising a support member, a planar member supported by the support member, and a tubular protruding member fixed to the support member and arranged to protrude outward from the planar member, wherein a first insulating material is provided on the outside of the planar member, a second insulating material is filled inside the protruding member, and the first and second insulating materials are arranged so as to be continuous in the thickness direction of the wall portion of the protruding member, sandwiched between the wall portion of the protruding member.

[0008] In the external insulation structure of the present invention, the second insulation material filled inside a cylindrical protruding member used in rooftop equipment racks and the like forms an insulation line between the first insulation material placed on the outside of a planar member such as a slab, making it easier to complete the external insulation than with conventional methods. This makes it possible to reduce or eliminate the need for insulation reinforcement on the indoor side, and provides an external insulation structure that can shorten the construction period.

[0009] The planar member is, for example, a slab, and the protruding member is, for example, a vertical column. The external insulation structure of the present invention can be applied, for example, to a rooftop space above a slab having an equipment rack including vertical columns.

[0010] It is preferable that the wall of the protruding member is provided with an injection hole for injecting the second insulating material. In this case, it is also preferable that the wall of the protruding member is provided with a confirmation hole at a position corresponding to the first insulating material for confirming whether the second insulating material has been filled. By providing an injection hole for the second insulation material in the wall of the protruding member, the second insulation material can be easily filled on-site. Also, by providing a confirmation hole for checking the filling of the second insulation material in a position corresponding to the first insulation material, the continuity with the first insulation material can be easily ensured by checking the filling through the confirmation hole.

[0011] It is preferable that a plugging material is disposed inside the protruding member to define the position of the end of the filling area of ​​the second insulating material on the planar member side. It is also preferable that the plugging material has an opening, and that the protruding member and the plugging material are plated. The above-mentioned plugging material allows the second insulating material to be filled only in the required area, leading to reductions in costs and construction time. In addition, the plugging material has openings, which prevents zinc from pooling on the protruding member to which the plugging material is integrated, making it possible to perform anti-rust plating treatment appropriately. Effect of the Invention

[0012] The present invention can provide an external insulation structure that can easily complete external insulation. [Brief description of the drawings]

[Diagram 5] A diagram showing an external insulation structure 1b. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

[0015] (1. External insulation structure 1) 1 is a diagram showing an external thermal insulation structure 1 according to an embodiment of the present invention. This external thermal insulation structure 1 provides insulation on the outside of a slab 13 supported by steel beams 11 and 12, and in particular relates to insulation around a vertical column 14 erected on the steel beam 11.

[0016] The steel beams 11 and 12 are respectively a main beam and a secondary beam in the ceiling part on the indoor side A below the slab 13, and are supporting members for supporting the slab 13. The space on the indoor side A is a space that requires a high level of cleanliness, such as a clean room, but is not limited to this.

[0017] The slab 13 is a planar member formed mainly of concrete, and in this embodiment, the outside of the slab 13 is the roof space on the outside side B.

[0018] The vertical column 14 is part of an equipment frame (not shown) for arranging equipment on the roof. The vertical column 14 is a cylindrical protruding member provided so as to protrude outward (upward) from the slab 13, and is made of a steel pipe or the like. The slab 13 rises around the vertical column 14, and the side of the base of the vertical column 14 is covered by this rising portion 131.

[0019] In this embodiment, gusset plates 15 are fixed to the lower surface of the end plate 140 at the lower end of the vertical column 14 and to the upper surface of the steel beam 11 by welding or the like, and the upper and lower parts of the splice plate 16 are fastened to these gusset plates 15 by bolts or the like. In this way, the vertical column 14 is fixed to the steel beam 11. The gusset plates 15 are arranged with a gap between them above and below, which suppresses heat conduction between the vertical column 14 and the steel beam 11.

[0020] In the external thermal insulation structure 1, a waterproof layer 2, thermal insulation materials 3 and 5, and supporting concrete 4 are provided on the outside of a slab 13. Reference numeral 6 in FIG.

[0021] The waterproof layer 2 is, for example, asphalt, and is provided so as to cover the outside of the slab 13 including the rising portion 131. However, the waterproof layer 2 is not limited to this, and may be any layer having waterproof performance.

[0022] The thermal insulating materials 3 and 5 (first thermal insulating material) are provided so as to cover the outside of the waterproof layer 2.

[0023] The heat insulating material 3 is a plate-shaped molded product made of resin such as polystyrene foam, and is arranged so as to cover the waterproof layer 2 above the slab 13 in a position other than the rising portion 131 of the slab 13.

[0024] The heat insulating material 5 is disposed so as to cover the waterproof layer 2 on the sides and above the rising portion 131 of the slab 13. The heat insulating material 5 is a spray material made of a resin such as urethane foam, and is sprayed onto the waterproof layer 2 covering the rising portion 131 from the outside of the rising portion 131.

[0025] However, the heat insulating materials 3 and 5 are not limited to these, and may be any material as long as it has heat insulating properties.

[0026] Furthermore, in this embodiment, the heat insulating material 7 (second heat insulating material) is injected into the cylindrical vertical column 14 to fill the inside of the vertical column 14. The heat insulating material 7 is, for example, a resin such as urethane foam, but is not limited thereto, and may be a cement-based material such as lean mixed mortar.

[0027] An injection hole 141 for injecting the insulating material 7 is provided in the wall of the cylindrical vertical column 14. Fig. 2 shows a horizontal cross section of the vertical column 14 at the height of the injection hole 141, and illustrates the state before being filled with the insulating material 7. As shown in Fig. 2, the cross section of the vertical column 14 is a rectangle with rounded corners, and the injection hole 141 is provided on one side of the vertical column 14.

[0028] The insulation material 7 is continuous with the insulation material 5 above the rising portion 131 of the slab 13 in the thickness direction of the wall portion of the vertical column 14, sandwiching the wall portion of the vertical column 14. As shown in Fig. 1, below the injection hole 141, a confirmation hole 142 for confirming filling of the insulation material 7 is provided in the wall portion of the above-mentioned side surface of the vertical column 14. The position (height) of the confirmation hole 142 corresponds to the position of the insulation material 5 above the rising portion 131 of the slab 13.

[0029] In this embodiment, the insulation materials 3, 5, 7 are almost continuous on the outside of the slab 13 (discontinuous only at the points where they contact the walls of the vertical columns 14), forming insulation lines as shown by the gray areas in FIG.

[0030] Inside the cylindrical vertical column 14, a blocking material 143 for defining the position of the end of the filling range of the insulation material 7 on the slab 13 side is provided below the confirmation hole 142. This is because, in order to form the above-mentioned insulation line, it is not necessary to fill the insulation material 7 up to the bottom end of the vertical column 14, and this is to avoid using more insulation material 7 than necessary.

[0031] 2, the blocking material 143 is a plate having one or more openings 1431, but the width of the openings 1431 is relatively small, so that the heat insulating material 7 does not penetrate into the lower end of the vertical column 14 through the openings 1431. Note that the blocking material 143 is not limited to this, and it is also possible to use a mesh member having a large number of openings.

[0032] The vertical column 14 is plated for rust prevention with the plugging material 143 installed inside. The opening 1431 of the plugging material 143 is a hole for removing the plating, which can prevent zinc pooling during the plating process.

[0033] (2. Method for forming external thermal insulation structure 1) When forming the external insulation structure 1, first the steel frame (steel beams 11, 12, vertical columns 14, etc.) is erected as shown in Figure 3(a), and then the slab 13 and waterproof layer 2 are constructed as shown in Figure 3(b).

[0034] Then, the heat insulating material 3 and the supporting concrete 4 are placed as shown in FIG. 3(c), and the heat insulating material 7 is filled inside the vertical pillar 14 as shown in FIG. 3(d).

[0035] The insulating material 7 is injected through the injection hole 141 of the vertical column 14, and filling is confirmed when the insulating material 7 leaks out from the confirmation hole 142. This makes it possible to confirm that the insulating material 7 has been filled to the height of the confirmation hole 142, i.e., the height that is continuous between the insulating material 5 and the wall of the vertical column 14. The injection hole 141 and the confirmation hole 142 may be sealed after filling with the insulating material 7.

[0036] Thereafter, the heat insulating material 5 is applied by spraying urethane foam onto the outside of the rising portion 131 of the slab 13, and the coping 6 and the like are installed, thereby forming the external heat insulating structure 1 shown in FIG.

[0037] As described above, according to this embodiment, the insulation material 7 filled inside the cylindrical vertical column 14 forms an insulation line between the insulation materials 3 and 5 arranged on the outside of the slab 13, and the external insulation can be completed more easily than with the conventional method. Therefore, it is possible to reduce or eliminate the insulation reinforcement on the indoor side A, and the construction period can be shortened.

[0038] Furthermore, if dry fireproof covering material is applied to the steel beams 11, 12 as a thermal insulation reinforcement for the indoor side A, condensation may occur due to moisture that has penetrated into the steel beams 11, 12 cooled through the slab 13 and into the fireproof covering material, which may cause a water leakage accident due to the condensed water. This embodiment can eliminate such water leakage accidents and provide a high-quality thermal insulation structure.

[0039] In this embodiment, an injection hole 141 for the insulation material 7 is provided in the wall of the vertical column 14, which allows easy filling of the insulation material 7 on-site. Also, a confirmation hole 142 for checking filling of the insulation material 7 is provided at a position corresponding to the insulation material 5, so that the continuity with the insulation material 5 can be easily ensured by checking filling through the confirmation hole 142.

[0040] In this embodiment, the plugging material 143 for defining the position of the end of the filling range of the insulation material 7 on the slab 13 side is provided inside the vertical column 14, so that the insulation material 7 can be filled only in the required range, leading to reduction in cost and construction time. In addition, since the plugging material 143 has the opening 1431, zinc puddles can be prevented for the vertical column 14 integrated with the plugging material 143, and anti-rust plating treatment can be suitably performed.

[0041] However, the present invention is not limited to the above embodiment. For example, in this embodiment, in order to suppress heat conduction from the vertical column 14 to the steel beam 11, a pair of gusset plates 15 are arranged with a gap between them and connected with a splice plate 16 to fix the vertical column 14 and the steel beam 11, but if the present invention can ensure thermal insulation performance, the gusset plate 15 can be omitted as shown in the external thermal insulation structure 1a in FIG. 4.

[0042] In the external thermal insulation structure 1a in Fig. 4, the end plate 140 at the lower end of the cylindrical vertical column 14a and the upper surface of the steel beam 11 are directly fixed with fasteners 17 made of bolts and nuts, without using a gusset plate 15. Therefore, the rising portion 131 of the slab 13a is omitted, and a larger roof space can be secured.

[0043] Furthermore, with the omission of the rising portion 131, the insulating material 5 is also omitted, and the insulation line on the outside of the slab 13a shown in gray in Fig. 4 is formed by the insulating material 3 above the slab 13a and the insulating material 7 inside the vertical column 14a. The insulating materials 3, 7 are continuous in the thickness direction of the wall portion of the vertical column 14a, sandwiching the wall portion (and the rising portion of the waterproof layer 2, described later).

[0044] For the purpose of shortening the construction period and improving the quality, the heat insulating material 7 is filled in the lower end of the vertical pillar 14a in advance at a factory or the like, and the plugging material 143 is omitted from the vertical pillar 14a. Note that the heat insulating material 7 can also be injected and filled on-site.

[0045] In addition, a water-stopping plate 144 protruding outward from the vertical column 14a is provided on the outer surface of the lower end of the vertical column 14a, and the ends of the waterproof layer 2 and the retaining concrete 4 on the vertical column 14a side are arranged to rise up to the height of the water-stopping plate 144 along the outer surface of the vertical column 14a.

[0046] Although the external thermal insulation structure 1 of this embodiment is applied to a rooftop space above a slab 13 having equipment racks including vertical columns 14, the application of the external thermal insulation structure of the present invention is not limited thereto. For example, the external thermal insulation structure of the present invention can also be applied to a case where a thermal insulation line is formed on the outside of a vertical exterior wall 13b, as shown in FIG. 5.

[0047] In the external heat insulation structure 1b in Fig. 5, an exterior wall 13b, which is a planar member on the outside (outside side B) of the structure, is supported by a supporting member such as a steel column 18, and a cylindrical cantilever member 14b (protruding member) fixed to the steel column 18 is provided so as to protrude outward from the exterior wall 13b. The cantilever member 14b is, for example, a balcony steel frame or a steel staircase support member, but is not limited to these.

[0048] A heat insulating material 3 is provided on the outside of the outer wall 13b, and a heat insulating material 7 is filled inside the cantilever material 14b. In the example of Fig. 5, these heat insulating materials 3 and 7 are arranged so as to be continuous in the thickness direction of the wall portion of the cylindrical cantilever material 14b, sandwiching the wall portion of the cantilever material 14b, and form a heat insulating line (shown as a gray part in Fig. 5) on the outside of the outer wall 13b. Reference numeral 8 in Fig. 5 denotes an exterior material provided on the outside of the heat insulating material 3.

[0049] In this embodiment, the indoor space is a clean room, but the use of the indoor space is not particularly limited, and the external insulation structure of the present invention can be used to form insulation lines in various buildings that require insulation, such as freezer warehouses and hot spring facilities.

[0050] Although the preferred embodiment of the present invention has been described above with reference to the accompanying drawings, the present invention is not limited to the above examples. It is clear that a person skilled in the art can come up with various modified or altered examples within the scope of the technical ideas disclosed in this application, and it is understood that these also naturally belong to the technical scope of the present invention.
