Description

  The present invention relates to a construction method for easily attaching a heat insulating material to the inner surface of a roof or wall of a building such as a factory or a warehouse.

  For example, slate tile roofs that are often used in buildings such as factories and warehouses are not heat insulating. Often required in addition.

  However, if you are going to install insulation on the inner surface of an existing roof or wall, you will have to rely on a specialist, you will need a foothold for the work, and the work will take time. There was a problem that a great deal of cost was required for the heat insulation work, for example, the use had to be suspended temporarily. The present invention is intended to solve such problems.

  Therefore, the present invention is a method of attaching a heat insulating material to the inner surface of a building in which a plurality of C-shaped steel materials having a C-shaped cross section are arranged in parallel at intervals, and is formed in a rectangular plate shape. A heat insulating material, an H-shaped steel member having an H-shaped cross section cut to substantially the same length as one side of the heat insulating material, and a protrusion that engages with an end portion of the H-shaped steel material is formed on one outer surface. A substantially U-shaped fastener, one side of the heat insulating material is inserted into the opening of the C-shaped steel material, and both opposite sides of the heat insulating material are inserted into the recesses formed on both sides of the H-shaped steel material and the H-shaped One end of the steel material is inserted into the opening of the C-shaped steel material, the H-shaped steel material is arranged so as to be orthogonal to the C-shaped steel material, and the fastener fixed to the other end portion of the H-shaped steel material is connected to the C-shaped steel material. Attached to the outer peripheral surface of the C-shaped steel material arranged in parallel with a distance from the shape steel material, the other end of the fastener is bent inward, Characterized by engaging the opening of the shape steel.

  According to the present invention, since the heat insulating material can be easily attached to the inner surface of the roof or wall of the building in a short time, the cost required for the heat insulating work can be greatly reduced.

  1 (a) to 1 (d) of FIG. In the figure, 1 indicates a part of a roof material of a building such as a slate tile factory building, and 2 and 3 are parallel to each other with an appropriate interval below the roof material so as to be a cross beam material for supporting the roof material. A C-shaped steel material 4 having a C-shaped cross section disposed in the shape 4 is a heat insulating material formed in a rectangular plate shape that can fit in the space between the C-shaped steel materials 2 and 3. In addition, as shown in the figure, the C-shaped steel materials 2 and 3 are disposed such that the openings 2a and 3a are obliquely upward along the inclination of the roof. Moreover, what is generally marketed and used now can be used for the heat insulating material 4, and many sheets are prepared according to the area of a roof.

  Reference numeral 5 denotes an H-shaped steel material cut to substantially the same length as one side of the heat insulating material 4. The H-shaped steel material has an H-shaped cross section as shown in FIG. Recesses 5a and 5b having a height h are formed on both sides in the figure. Further, the protrusions 6a and 6b are formed on the upper surface and the lower surface in the figure, so that the engagement grooves 7a and 7b having the width s are formed.

  8 is a substantially U-shaped fastener formed of a strip-shaped steel material, and the fastener 8 has a pair of plate-like protrusions 9a on one outer surface as shown in FIGS. , 9b are integrally formed, and the projections 9a, 9b are fitted into the engaging grooves 7a, 7b so that the fastener can be fixed to the end of the H-shaped steel material 5. Further, the other end portion 10 of the fastener 8 is bent in a hook shape. The other end portion 10 is formed with a hardness that can be easily folded by an operator using a hand or a hand tool and applying pressure.

  When the heat insulating material 4 is attached to the inside of the roof material 1, first, as shown in FIG. 1 (a), one side 4a of the heat insulating material 4 is inserted into the opening 2a of the C-shaped steel material 2 and FIG. 4) and the opposite sides 4b, 4b of the heat insulating material 4 are inserted into recesses 5a, 5b formed on both sides of the H-shaped steel material 5, and one end of the H-shaped steel material 5 is connected to a C-shaped steel material. The H-shaped steel material 5 is placed so as to be orthogonal to the C-shaped steel material 2 by being inserted into the two opening portions 2a.

The fastener 8 secured to the other end portion of the H-shaped steel material 5 with respect to the C-shaped steel material 3 disposed in parallel with the C-shaped steel material 2 at intervals is shown in FIG. Apply as shown in 3 (a). This deposition operation can be easily performed without lifting a special tool by simply lifting the fastener 8 from the lower side with respect to the C-shaped steel material 3. Then, the operator pushes up the other end portion 10 of the fastener 8 by hand as indicated by an arrow in FIG. 3 (b), and the other end portion 10 is bent inward, thereby the other end portion. 10 is engaged with the opening 3 a of the C-shaped steel material 3. As a result, as shown in FIGS. 1D and 5, the fastener 8 is fastened to the C-shaped steel material 3, and the heat insulating material 4 can be easily placed between the C-shaped steel material 2 and the C-shaped steel material 3. Can be attached.
In addition, by attaching the heat insulating material 4 in this manner, the heat insulating material 4 is supported by the C-shaped steel material 2 on one side 4a and supported by the H-shaped steel materials 5 on both sides 4b and 4b, so that it falls. It is not, and it is attached securely.

Similarly, by using the H-shaped steel material 5 and the fastener 8 and attaching a large number of heat insulating materials 4 between the C-shaped steel material 2 and the C-shaped steel material 3 and between the other C-shaped steel materials, The entire inner surface can be covered with the heat insulating material.
In addition, also about the inner surface of the wall of a building, the heat insulating material 4 can be attached between the C-shaped steel materials arrange | positioned in parallel with the same construction method.

  As described above, according to the present invention, the heat insulating material can be attached by a simple work, and the heat insulating work can be performed in a short time by using a stepladder or an aerial work vehicle without providing a scaffold for the work. Since it can be completed, the cost for construction can be greatly reduced.
