Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for constructing a heat insulating roof, and an object of the present invention is to provide a method for constructing a heat insulating roof that can be easily constructed and has an excellent heat insulating effect. be.

The present invention will be described in detail below based on embodiments shown in the figures.

Both the lower metal plate 1 and the lower metal plate 4 have peaks 6, 7 and valleys 8,
9 are formed into a continuous wave shape, and the dimensions, that is, the cross-sectional shapes thereof, are the same.

As the heat insulating material 3, a sheet of organic or inorganic porous material such as soft urethane foam, glass wool, asbestos, or rock wool is used. The insulation roof A is constructed by sandwiching the insulation roof A, and when constructing the insulation roof A, support members 5 are placed at appropriate intervals on the horizontal members 2 such as the main building shown in FIG. The fixing rods 5a are provided protrudingly as shown in FIG. niuketsuba 1
0. Insert the fixing bolt 11 that protrudes upward.

Thereafter, the heat insulating material 3 is spread over the entire upper surface of the lower metal plate 1, and the spacer 12 is attached to the fixing bolt 11.

Here, the spacer 12 is formed of synthetic resin into a cylindrical shape with a hollow interior, and has a lower female threaded portion 13 and a lower female threaded portion 14 formed at both upper and lower ends, respectively.
is screwed onto the fixing bolt 11, and the lower metal plate 1 is sandwiched between the tongue piece 15 extending from the outer periphery of the lower end of the spacer 12 and the receiving flange 10.

Here, if the tongue piece 15 is fitted onto the fixing bolt 11 as shown in the figure and a synthetic resin washer 16 such as neoprene is pressed against the lower metal plate 1, the distance between the spacer 12 and the lower metal plate 1 can be improved. It can be sealed watertight.

Also, as shown in the figure, when two lower metal plates 1.1 are joined on one fixing rod 5a, the peak 6 at the end of one lower metal plate 1 and the ridge 6 at the end of the other lower metal plate 1 When the ridge portions 6 are overlapped on the receiving flange 10, a sealing material is injected between the Okayama portions 6 and 6 to seal the gap watertightly.

After the heat insulating material 3 is spread over the lower metal plate 1 in this way, the lower metal plate 4 is arranged so that its peaks 7 and troughs 9 match the peaks 6 and troughs 8 of the lower metal plate 1. The fastening bolt 17 screwed onto the upper female threaded part 13 of the spacer 12 is inserted into the through hole provided in the peak part 7 of the lower metal plate 4 over the heat insulating material 3, and then inserted from above the lower metal plate 4 like a felt packing. The nut 20 is screwed onto the fastening bolt 17 through the packing material 18 and the bent portion 19, and the lower metal plate 4 is attached to the lower metal plate 1 through the spacer 12.
The heat insulating material 3 is sandwiched between the upper and lower metal plates 1 and 4.

Here, the fastening bolt 17 screwed into the spacer 12 and the fixing bolt 11 are designed so that they are not directly continuous.
This prevents heat bridges from forming between the bolts 11, 17.

In addition, in this case as well, as with the lower metal plate 1, the spacer 12
When joining the lower metal plates 1 and 4, the upper metal plate 4.
A sealing material is injected into the overlapped portions of the four ends to connect the two in a watertight manner.

By the way, when the lower metal plate 4 and the lower metal plate 1, which have a corrugated cross section of the same size, are overlapped, the distance t2 between the ridges 6 and 7 and between the troughs 8 and 9 is the same at other points. The heat insulating material 3 has a thickness that is larger than the interval t1, but approximately equal to the height of the spacer 12 corresponding to the interval t2 between the peaks 6 and 7.
By using the heat insulating material 3, the peaks 6, 7 and the valleys 8,
In areas other than 9, it is compressed between the upper and lower metal plates 1 and 4 and flows to the peaks 6 and 7 and the valleys 8 and 9, and is evenly filled throughout the area. Even if it is thinner than the spacer 12, this deficiency can be compensated for by compressing the heat insulating material 3 in areas other than the peaks 6.7.

In the figure, 21 is a synthetic resin cap that covers the fastening bolt 17, nut 20, bent part 19, and packing 18 that protrude from the lower metal plate 4, and its lower end is brought into close contact with the lower metal plate 4 to make these members watertight. This prevents rainwater from penetrating into the insulation material 3.

The embodiment shown in FIG. 2 shows an example in which a tight frame 5b is disposed on the horizontal member 2 as the support member 5, and is secured by fixing bolts 11 protruding from the upper surface of the tight frame 5b in the same manner as in the previous embodiment. Therefore, the insulated roof A will be constructed.

In each of the above embodiments, female threads are directly carved into the spacer 12 made of synthetic resin to form the upper female threaded portion 13 and the lower female threaded portion 14.
Although the present invention is not necessarily limited to this example, for example, as shown in FIGS. 4 and 5, a spacer body 12a made of synthetic resin is used.
A spacer 12 may be used in which an upper female threaded portion 13a and a lower female threaded portion 14b made of metal are inserted above and below, respectively.

In this case, the lower female threaded portion 13a and the lower female threaded portion 14a are spaced apart from each other to prevent the spacer 12 from acting as a heat bridge between the fastening bolt 11 and the fixing bolt 11.

In the embodiment shown in FIG. 3, the lower metal plate 4 and the lower metal plate 1 are connected by using a synthetic resin spacer 12 in which a metal embedded fastening bolt 22 and an embedded metal nut 23 are embedded in the upper and lower ends, respectively.
An example is shown in which the fixing bolt 11 protruding from the receiving flange 10 is screwed into the embedded nut 22, and the embedded fastening bolt 22 is inserted into the through hole of the lower metal plate 4 to attach the lower metal plate. The nut 20 is screwed onto the embedded fastening bolt 20 from above the plate 4.

In this case, as shown in FIGS. 6 and 7, the metal embedded fastening bolts 22 and embedded nuts 23 are not continuous with each other but are embedded in the synthetic resin spacer 12c. A heat bridge is not formed between the metal plate 1 and the metal plate 1.

Here, in the spacer 12c shown in FIG. 7, a cavity 2 is formed between the embedded fastening bolt 22 and the embedded nut 23.
4 has a diameter larger than that of the fixing bolt 11 that is screwed into the embedded nut 23, and the upper end of the fixing bolt 11 fits into this cavity 24, but of course the length of this cavity 24 must be sufficient. This prevents the fixing bolt 11 from coming into contact with the upper embedded bolt 22.

Since the present invention is constructed as described above, it is possible to use the synthetic resin spacer to prevent the occurrence of heat bridges between the upper and lower metal plates. The joints between the peaks are tightened together to prevent rainwater from entering from these areas, and the overlap between the peaks at the end of the lower metal plate is tightened through a sealing material, which improves airtightness. This prevents indoor moisture from penetrating between the upper and lower metal plates through the lever part, and as a result, even on the roof of a factory where moisture is generated indoors, the moisture generated indoors can cause the layers to stack up between the upper and lower metal plates. The insulation material is not damaged by moisture, and since there is insulation material between the two continuous lower metal plates, the insulation material is not damaged by moisture. The insulation material is filled without any gaps between the insulation material and the lower metal plate, which prevents condensation from forming on the surface facing the insulation material, and as a result, the insulation material is not damaged by condensation. .

As described above, according to the construction method of the present invention, the heat insulating material is not deteriorated by moisture generated indoors, no dew condensation occurs inside, and the heat insulating material is not deteriorated by condensed water.

In addition, the ends of the lower metal plates are overlapped vertically on the support member, and the ends of the lower metal plates are overlapped vertically above this via the insulation material, so it is strong against snow loads, etc. .

Further, according to the present invention, after a heat insulating material is spread over the entire upper surface of the lower metal plate, a lower metal plate having the same size and shape as the lower metal plate is successively placed on the heat insulating material, and the lower metal plate provides insulation. Since the material is compressed and the insulation material is filled between the upper and lower metal plates without any gaps, it is possible to install the insulation material on-site without having to install the insulation material in advance on the lower metal plate or between the upper and lower metal plates as in conventional methods. Just by placing it on the lower metal plate, it will be compressed by the lower metal plate that will be covered later, and will naturally deform between the lower metal plates to match the waveform of each metal plate. Therefore, the distance between the two metal plates is approximately equal, and this has the advantage that the same metal plate can be used for the lower metal plate and the insulation roof can be easily assembled and constructed.

Furthermore, according to the present invention, the lower female threaded portion of the lower part of the synthetic resin spacer, which has the lower female threaded portion at the upper portion and the lower female threaded portion at the lower portion spaced apart from the lower female threaded portion, is screwed onto the fixing bolt on the lower metal plate. The overlapping portion with the sealant interposed therebetween is sandwiched between the support member and the spacer, and the tightening bolt whose lower part is screwed into the lower female threaded part of the upper part of the spacer is inserted between the peaks of the lower metal plate. The spacer is fixed to prevent heat bridges by inserting it into the overlapped part and screwing the nut onto the tightening bolt on the lower metal plate to sandwich the overlapped part between the nut and the spacer. The end of the lower metal plate can be fixed to the support member by directly screwing into the bolt, without requiring any additional screws, etc., and the ends of the lower metal plate stacked above and below can be clamped together. It is easy to construct,
Moreover, the lower metal plate can be fixed to the supporting member via the spacer without the need for additional screws by simply screwing nuts onto the fastening bolts protruding from the spacer to prevent heat bridges, and the lower metal plate can be stacked on top and bottom of the lower metal plate. The combined ends can be fastened together, and the lower metal plate can also be easily constructed.
