BACKGROUND OF THE INVENTION
The present invention relates to a method for attaching a heat insulating material and a metal fitting used therefor.
[0002]
[Prior art]
Conventionally, when attaching and fixing a heat insulating material between studs or joists, a method of attaching a heat-insulating material to the pillars or joists on both sides of the space constituting the heat-insulating material mounting space and attaching the heat insulating material to the metal fittings Is used. Specifically, as the metal fittings, an attachment surface to the joist, a wall surface suspended from the attachment surface edge and formed at a height corresponding to the thickness of the heat insulating material to be attached, and the lower end of the wall surface A heat insulating material support surface extending horizontally from the edge; a claw-like protrusion protruding upward from the edge of the support surface; and a mounting protrusion suspended from the opposite edge of the attachment surface Using a metal fitting, the metal fitting is placed so that its attachment surface is in contact with the top surface of the joist, and the mounting protrusions are driven into the joist upper surface, and are attached to the joists on both sides of the heat insulating material installation space, and then the heat insulating material is installed. Push the heat insulating material into the space until the heat insulating material hits the heat insulating material support surface of the metal fitting while the nail protrusions of the metal fitting are stuck into the heat insulating material. After attaching a heat insulating material in this way, board materials, such as a floor board, were attached from the top.
[0003]
By the way, according to the above method, if the thickness of the heat insulating material and the height of the wall surface of the metal fitting are slightly different, various adverse effects occur. It is necessary to prepare metal fittings to have, and the present situation is that various types of heat insulating materials having different thicknesses are used in accordance with the type of structure and the attachment site of the heat insulating material. The above-mentioned adverse effects are as follows. That is, when the thickness of the heat insulating material is thicker than the height of the wall surface of the metal fitting, the floor material cannot be fixed to the joists because a gap is generated between the floor plate to be attached later and the joists. Moreover, when the thickness of a heat insulating material is thinner than the height of the wall surface of a metal fitting, a clearance gap will be produced between a heat insulating material and a floor board, and a heat insulation effect will be reduced remarkably.
[0004]
[Problems to be solved by the invention]
However, it is extremely complicated to produce metal fittings having various wall heights corresponding to the heat insulating materials of various thicknesses, and to select and use it according to the thickness of the heat insulating material to be used. Inadvertently attaching the mounting part of the bracket, or inadvertently attaching the wrong insulation material to the bracket that has been mistakenly noticed. This resulted in work, making the construction work inefficient and costly.
[0005]
In addition, since there is usually some dimensional variation for each product in both the bracket and the insulation, the dimensional error between the bracket and the insulation is within the appropriate error range at each installation location. The problem is whether or not it is within. However, there has been a problem that much time and labor are required to select a combination of a metal fitting and a heat insulating material so that a dimensional error is within an appropriate range.
[0006]
When the thickness of the heat insulating material is somewhat too thick, the surface of the heat insulating material is shaved and used at the construction site. However, it is extremely difficult to process the thickness within an appropriate range, and performing such processing at the installation site is cumbersome and extremely deteriorates the work efficiency.
[0007]
SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and a method of attaching a heat insulating material that eliminates the above-described conventional disadvantages and can perform fixing and fixing of the heat insulating material efficiently and in a short time at low cost, and a metal fitting used therefor The purpose is to provide.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory diagram for explaining a method for attaching a heat insulating material according to the present invention. In the present invention, as shown in FIG. 1, in order to install and fix a heat insulating material between pillar structures such as between columns, between studs, or between joists, first, the metal fitting 1 for attaching the heat insulating material is insulated. It fixes to each of the frame structure materials 3 and 3 which form the attachment space 2 in the both sides of the attachment space 2 to which a material is attached, by suitable fixing means, such as a nail. The metal fitting 1 has a surface 4 for attachment to a structural material, a wall surface 5 extending from the attachment surface 4 toward the attachment space 2, and provided on the wall surface 5 at right angles to the attachment surface 4. It is composed of a planar protrusion 7 having an inclined edge 6 which is substantially perpendicular and rises gradually from the mounting surface 4 side. The metal fitting 1 is attached and fixed to the structural material 3 by its attachment surface 4. The attachment surface 4 is provided with, for example, a nail hole or a nail for attachment to a structural material. The wall surface 5 is preferably provided so as to be perpendicular to or substantially perpendicular to the mounting surface 4.
[0010]
Next, a wide surface 8a on the front side of the heat insulating material mounting space 2 (hereinafter, the heat insulating material mounting direction side is the back side and the opposite side is the front side) is the front side of the space 2 It is arranged so as to face substantially parallel to the virtual plane 2a on the side (the same surface as the front surface of the structural member 3), that is, so as not to be inclined with respect to the space 2, and the heat insulating material 8 is kept in that state. Push into the mounting space 2. And the heat insulating material 8 is installed in the mounting space 2 while the inclined edge 6 of the surface protrusion 7 acts like a blade so that the surface protrusion 7 of the metal fitting 1 is cut into the heat insulating material 8 from the inclined edge 6 side. Keep pushing. As the heat insulating material 8, a plate-like foam made of a synthetic resin is preferable. In particular, a polystyrene-based resin plate-like foam or a polyolefin-based resin plate-like foam having a thickness of 20 to 200 mm and an expansion ratio of 20 to 150 times. The body is desirable.
[0011]
When only the heat insulating material 8 is attached first, the wide surface 8b on the near side of the heat insulating material 8 is flush with the surface 4 for attaching the metal fitting 1 (close to the virtual plane 2a on the near side of the space 2). When the state becomes, the pushing of the heat insulating material 8 is stopped. The attached heat insulating material 8 becomes a form supported by the frictional force between both surfaces of the planar protrusion 7 and the cut inner surface of the heat insulating material 8 in contact with the surface.
[0012]
Then, from above, as shown in FIG. 2, for example, an interior material such as an inner wall material or a floor board material, an exterior material such as an outer wall material, or a plate material 9 such as a base material, the back surface 9a is a surface 4 on which the metal fitting 1 is attached. The plate material 9 is provided in the upper layer of the heat insulating material 8. 1 and 2, the metal fitting 1 and the structural material 3, the heat insulating material 8 and the plate material 9, and the plate material 9 and the metal fitting 1 are expressed as being separated from each other for convenience. Usually, the mounting surface 4 of the metal fitting 1 is in close contact with the structural material 3, the wall surface 5 of the metal fitting 1 is in close contact with the structural material 3, and the heat insulating material 8 and the plate material 9 are in close contact with each other. The plate 9 is brought into close contact with the mounting surface 4 of the metal fitting 1. The same applies to FIGS. 3 and 4 below.
[0013]
In the present invention, after attaching the metal fitting 1 to the structural material 2 and attaching the heat insulating material 2, in addition to the above, for example, as shown in FIG. It is also possible to place a plate material 9 such as a floor plate material on the side and push the two into the mounting space 2 at a time in a state in which both are stacked and in close contact with each other. Although not shown, the heat insulating material 8 is disposed at the entrance of the space 2 or, as shown in FIG. 4, a certain depth into the space 2, that is, the surface 8 b is larger than the surface 4 for mounting the metal fitting 1. Either push it to a depth that still projects to the near side (a mode in which the heat insulating material 8 is in contact with the inclined edge 6 of the planar protrusion 7 or cut the planar protrusion 7 into the thermal insulating material 8 to some extent) And the board material 9 is pushed in as a state in which the board material 9 such as a floor board material is overlapped and brought into close contact with the heat insulating material 8 (on the front side). The heat insulating material 8 can also be pushed in. Also in these cases, the pressing of the plate material 9 is stopped when the back surface 9a of the plate material 9 comes into contact with the mounting surface 4 of the metal fitting 1, so that the back surface 9a of the plate material 9 is finally used for attaching the metal fitting 1. It will be in the state contact | abutted to the surface 4 of this.
[0014]
According to the method in which these plate materials 9 are pushed over the heat insulating material 8, the cushioning property of the heat insulating material 8, specifically, the elasticity to the force in the compression direction, that is, the compression deformation recovery property, the state of compression adjustment at the time of pushing The resulting heat insulating material 8 applies a force to the plate material 9 so as to elastically push up in the compression deformation recovery direction from the back surface side of the plate material 9 in a state after the pushing is completed. As a result, it is preferable because a reliable adhesion state can be maintained between the plate material 9 and the heat insulating material 8 even after the pressing is completed.
[0015]
First, in the above-described method in which only the heat insulating material 8 is completely pushed into the space 2, there is a possibility that the heat insulating material 8 and the plate material 9 may be pushed too much, and a gap may be formed between the heat insulating material 8 and the plate material 9. Then, there is no such a fear, and even after the plate material 9 is attached, the contact state between the heat insulating material 8 and the plate material 9 can be reliably maintained. In the method shown in FIG. 4, the heat insulating material 8 is not first made to a very strict depth and is not necessarily the same for each of the front, rear, left and right heat insulating materials 8. As long as it is pushed to an appropriate depth, the front side surface is automatically aligned with the plate material 9 so that it can be in close contact with the plate material 9. There is no hassle.
[0016]
As described above, the heat insulating material is attached and fixed in the heat insulating material mounting space between the structural materials. Thus, according to the method of the present invention, it is possible to simply attach and fix the heat insulating material by simply attaching the metal fitting to the structural material and then pushing the heat insulating material into the mounting space.
[0017]
When the method of the present invention is implemented and the heat insulating material 8 thicker than the height of the wall surface 5 of the metal fitting 1 is completely accommodated in the space 2 and attached, as shown in FIGS. The back surface 8a of the metal fitting 1 protrudes further to the back than the innermost portion of the metal fitting 1. In such a state, the exposed portion of the metal fitting 1 from the inside of the heat insulating material 8 to the outside is extremely small and it is difficult to form a heat bridge portion (cold bridge portion). It is more effective in improving the temperature and preventing indoor condensation.
[0018]
Next, the metal fitting of this invention is demonstrated. The metal fitting of the present invention is used for carrying out the above-described heat insulating material attaching method, and is shown as an example in FIG. 5 and configured as described above. The metal fitting of the present invention can push the heat insulating material infinitely in the mounting space so that the mounting method can be carried out regardless of the thickness of the heat insulating material. That is, it does not have the component which regulates the penetration depth into the installation space of a heat insulating material. Therefore, if the metal fitting of the present invention is used, it is possible to simply mount and fix the heat insulating material so that the mounting state is perfect by using the above method, regardless of the thickness of the heat insulating material.
[0019]
The number of the planar protrusions 7 provided on the metal fitting 1 may be one or two or more. Further, the inclined edge 6 of the planar protrusion 7 may be linear or curved. The planar protrusion 7 is perpendicular to the mounting surface 4 so that the inclined edge 6 can be cut into the heat insulating material 8 when the heat insulating material 8 is pushed in the mounting space 2 direction. Or it is provided so that it may become a substantially right angle. Although the planar protrusion 7 is provided at a right angle to the wall surface 5 in the drawing, it does not necessarily have to be at a right angle to the wall surface 5. In the figure, the mounting surface 4 and the wall surface 5 are also perpendicular, but this is not always necessary.
[0020]
【Example】
Next, the metal fitting of the present invention will be described in more detail with reference to FIG. The metal fitting 1 has a substantially cross-sectionally U-shaped metal fitting that is open at both sides in the lateral direction and a lower portion thereof, and the front and rear direction surfaces thereof are the wall surfaces 5a and 5b, respectively, and the upper surface is the mounting surface 4. From the end edges 51a, 51a, 51b, 51b of the wall surfaces 5a, 5b in the respective portions of the openings 10, 10 on both sides in the lateral direction, the mounting surfaces are perpendicular to the wall surfaces 5a, 5b and the mounting surface 4. The lower surface 11 has an inclined edge 6 that gradually rises from the wall surface 5 side as it goes downward from the surface 4 side, and the lower edge 11 extends from the surface projection 7 in the shape of a right triangle parallel to the surface 4 for attachment. A projection 12 for mounting on a triangular piece-like structural material is provided in a downward projecting manner at a symmetrical position on the front-rear side across the central portion of the.
[0021]
The metal fitting 1 is a flat metal fitting having a shape as shown in a developed view of FIG. 6 as a whole. After being obtained by pressing or cutting, or by simultaneous pressing, the portion indicated by the solid line a in FIG. The portion indicated by the alternate long and short dash line b in the figure is folded at a right angle, the portion indicated by the alternate long and two short dashes line c in the figure is folded at a right angle, and the tip side from the a line is formed as a mounting projection 12 and sandwiched between b and b. This portion was obtained as the mounting surface 4, the portions surrounded by b and c were the wall surfaces 5 a and 5 b, respectively, and the end portion side from c was the planar protrusion 7.
[0022]
【The invention's effect】
Since the method for attaching a heat insulating material according to the present invention is configured as described above, it can be applied to heat insulating materials having different thicknesses without requiring any special work. Therefore, it is possible to prevent the mounting position of the metal fittings from being mistaken or the wrong combination of the heat insulating material and the metal fittings, and as a result, there is no need for re-installation. Moreover, it is not necessary to process the heat insulating material at the construction site. Thus, according to the method of the present invention, the labor and time required for construction can be significantly reduced, which contributes to reduction of construction cost.
[0023]
In addition, a method of pushing the heat insulating material into the installation space by pushing the heat insulating material into the mounting space, then placing the plate material on the heat insulating material and pushing the plate material into the space. If there is used, there is an advantage that the state of close contact between the heat insulating material and the plate material can be reliably maintained without taking time and effort.
[0024]
In addition, if the metal fittings of the present invention are used, it is only necessary to prepare the minimum type of specification that can be attached to the structural material. It can also be applied to. Therefore, even when a plurality of types of heat insulating materials having different thicknesses are used, the above mounting method can be applied using a much smaller type of metal fittings than in the past, and the labor required for the heat insulating material mounting operation The construction cost can be reduced by reducing the time.
