Description

[Detailed Description of the Invention] V. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a method for roofing houses, etc., and more specifically, to a method for roofing existing roofs covered with metal plates, asbestos plates, etc. The present invention relates to a particularly effective roofing method when applying a new roofing material.

[Conventional technology]

The roofs of houses receive the most solar energy, and some of the heat received on the roof is accumulated in the attic, gradually raising the indoor temperature. For this reason, methods of installing insulation materials such as glass wool in the attic are increasing, but the reality is that the insulation effect of glass wool etc. decreases over the long term due to the absorption of condensed water in the attic. It must be assumed that the insulation effectiveness of old roofs of existing buildings has decreased considerably. Furthermore, there are quite a number of fortune-telling buildings that do not use insulation at all.

Additionally, in the summer, it is important to block the conduction of outside heat into the room, and in the winter, due to the spread of heating equipment, it is common for indoors to be hot and outdoors to be cold. , condensation tends to occur at the interface between indoors and outdoors,
Long-term accumulation of water droplets can cause rust, especially in the case of metal roofing materials, from the back side, leading to corrosion and leaks.

Furthermore, in cold and snowy regions such as Hokkaido and the Tohoku region, as shown in FIG. 7, snow on the roof 6 often forms wood fields and icicles 6 on the eaves, causing a leakage phenomenon. This leakage occurs when the snow on the roof melts in the upper part of the room due to the rise in temperature caused by indoor heating, but at the eaves, it freezes due to the cold air outside and forms a dam, and the melted water 7 accumulates in the gaps between the roofing materials. It refers to the current collection that goes into the room from 711. The ways to prevent roof leaks are to eliminate imbalances in the temperature distribution on the roof surface and to prevent woody areas from forming under the eaves. temperature minute 4
As a method to improve the air temperature, circulating the indoor temperature at the eaves has been advocated, but this method can only be applied to newly constructed buildings. As a way to prevent wood from forming, installing hot water vibrators, electric heaters, etc. at the eaves has been considered, but the installation cost is expensive.
However, when there is no snow, it becomes a useless item.

[Problem that the invention seeks to solve]

In order to solve all the problems mentioned above, in newly constructed buildings,
As shown in the figure, air is taken in from the ceiling of the building 1, entered into the attic, and exhausted from the ridge, or as shown in Fig.
Furthermore, there is a method in which the water is returned to under the floor from an indoor space or a vertical duct.

However, while these construction methods are relatively easy for newly constructed buildings, applying them to existing buildings requires extensive renovation work, which is currently impossible.

In addition, as a roof repair method for existing buildings, as shown in Figure 10, there are many overlapping methods in which new roofing material 5 is completely covered over the existing roof girder. Since the roof 3 and the new roofing material 5 are in close contact with each other,
The problem is that there is not enough space for air to circulate.

Furthermore, as shown in Fig. 11, when replacing the soil on the existing roof 3 with supplementary metal molded tiles 5, an air layer 4 is created between the two.
At first glance, it appears that ventilation is possible. However, as shown in Fig. 12, if air intake and exhaust means are not provided at the eaves and ridges, the air layer 4 will easily become warm in the summer because a metal plate with high thermal conductivity is used alone. There is a problem in that heat is dissipated into the ceiling, raising the overall indoor temperature, and in winter, the difference in temperature and humidity inside and outside the building causes condensation on the back side of the roofing material.

The present invention was made to solve the above-mentioned problems, and by providing a layer that allows ventilation from the eaves to the ridge, it has a heat shielding effect on the attic in the summer, a dew condensation prevention effect on the attic in the winter, and an effect on the eaves. The objective was to obtain a roofing method with superior leakage prevention effects.

[Means and operations for solving the problem] The present invention has been made to achieve the above object, and the surface is three-dimensionally formed in y-alignment with the shape of the roofing material, and the back eave part is formed three-dimensionally. A base material having a horizontal notch and a plurality of ventilation grooves reaching from the tip of the eaves to the edge of the ridge side is placed on top of the entire roof, the roofing material is fixed on top of the base material, and outside air is sucked in from the eaves. The ventilation system for all of the base material is led to the ridge side, and the ridge is made up of corrugated sheets and flashing plates arranged in two tiers, and the water is discharged to the outside through the kasagi, kasagi holder, etc. It provides all the methods for roofing a house, etc.

〔Example〕

FIG. 1 is a sectional view showing an embodiment of the present invention.

First, the members forming each part will be explained. In the figure, 11 is a vertical crosspiece with a rectangular cross section, and in the example, the length is 1
00 to 300 m was used. Reference numeral 12 denotes an eave hanger made of a metal material and having a stepped cross section.As shown in Fig. 2, the central flat part has a small hole for air inflow (in the example, the diameter is 1 to 7 mm).
wR) or a plurality of elongated slits 13 are provided.

Incidentally, the small holes, slits, etc. 16 may be covered with stainless steel netting or saran netting tubes to prevent insects. 14 is new roof material 20
This base material is made by integrally molding a plastic foam such as styrofoam, urethane foam, or phenol foam, or by integrally molding a binder and an inorganic lightweight foam such as perlite, shirasu balloon, or vermicrite. As shown in FIG. 3, this base material 14 is three-dimensionally molded so that its surface matches the shape of the new roof material 20. On the back eave side, there is a notch 15 (deep in the example) extending across the entire width. Sa20kaku, depth (width) 20~100ra
), and a plurality of ventilation grooves 16 (in the example, a depth of 13 m, a width of 13 m and an interval of 27.s t, s) are formed from the eave side to the ridge side. Incidentally, a large flap groove 17 into which the vertical flap 6a fits may be provided between the ventilation grooves 16 in accordance with the interval between the vertical flaps 3a of the pre-deposited roof. In the embodiment, the base material 14 is shown to be of a size that would be used when five sheets of new roofing material are consecutively arranged in the horizontal direction and in five rows in the vertical direction, but the number of sheets and the number of stages can be changed as appropriate.

20 is a ν roofing material, and in the non-example, 5 consecutive metal molded tiles were used in the horizontal direction. 21 is a corrugated plate made of metal plate or plastic plate (JISG3302 and JISG
3312), @4G(lL), it is formed in liquid form, or as shown in (b) to (d), it is formed with angular waves, ripple waves, etc. at appropriate intervals.

22 is the first cap, 23 is the XS-shaped first rain restraining plate, 2
4 is the first Kasagi uke. Reference numeral 25 designates a second cap plate made of processed wood or metal plate, an example of which is shown in FIG.

A wavy line 26 is made of the same material as the corrugated plate 21, and is bent at the center metal in the length direction to form a substantially F-shape.

27 is a second cap, and 28 is a second C-shaped flashing plate.

In addition, 8 is a sheath board of an existing roof, 9 is a fascia, 6 is an existing roofing material that was roofed on the sheath board 8, and 10 is a gate board.

Next, a roof re-roofing method according to the present invention using all of the above-mentioned members will be explained.

(1) As shown in Figure 2, nail the protrusions to the vertical strips 11' at predetermined intervals to the eaves of the Kaiai b @ Neotsu (in the example, the dimensions of the protrusions are 20 to 100 squares). Met). In addition,
In order to maintain a predetermined spacing, vertical crosspieces 11 may be fixed along the vertical seams 3& of the repaired roof 3.

(2) Nail the eaves hangers 12 to the small ends of the vertical beams 11 and the wide and small sections 9a of the repaired roof 3.

(3) Place the base material 14 on the repaired roof 6 in order from the eaves side to the ridge side. At this time, a space is formed by the notch 15 provided on the eaves side of the base material 14 and the eave hanger 12, and outside air is sucked in through the small hole 16 of the eave hanger 12 and guided to the base material 140 ventilation groove 16. It acts as a landing place. In addition, when connecting the base material 14 in the direction of the ridge, the notch 15 is
Since it is overlapped with the ridge-side end of the base material 14 previously placed, the two are connected without any gaps. As a result, ventilation groove 1
Since the connectivity of 6 is maintained and heat loss is eliminated, good heat insulation properties can be obtained. Note that there is a large groove 1 in the base material 14.
7, this groove 17 may be fitted into the vertical seam 6& when the base material 14 is placed on the repaired roof 3.

(4) Cover the base material 14 with the new roofing material 20. Using the base material 14 as a guide, the new roofing material 20 is successively raised from the eaves to the ridge direction, and the ridge side is fixed by nailing via hangers 20a-v.

(5) Place the new roofing material 20 on the ridge side end and the flap material 10 of the repaired roof 6 on the corrugated sheet 21' and fix it.

As a result, a space B is formed between the repaired roof 6 and the corrugated sheet 21.

(6) Place the first cap 22 on the corrugated plate 21, and
Place the first Kasagi support 24 near the 20 building side and secure it with nails.

(7) Fix the second cap holder 25 to the top of the Aoshi board 10 by nailing it. The height of the second Kasagi receiver 25 is such that the line connecting its top and the top of the first Kasagi receiver 24 is y-parallel to the line at the top of the tilt plate 10.

(8) Align the bent part of the wavy line 26 with the center of the ridge of the repaired roof 3, place it on the first and second cap supports 24 and 25, and secure it by nailing. As a result, a space C is formed.

(9) Place the second Kasagi 27 on the wavy line 26, and
Fix by nailing to the Kasagi receiver 24.25.

αQ The first flashing plate 23 is placed on the first cap 22 and fixed by nailing to the sides of the first cap 22 and the first cap support 24.

α-i Place the second flashing plate 28 on the second cap 27 and secure it by nailing from the side.

The replacement of the roof has now been completed. Although I have omitted the explanation, it goes without saying that the opposite slope of the repaired roof will be reroofed in the same way.

According to the roof re-roofed as described above, there are 12 eaves hangers.
The outside air sucked through the small hole 13 is, as shown by the arrow,
Space A → Ventilation groove 16 of base material 14 → Space B → Corrugated plate 21 →
It is discharged to the outside via space C → wave ridge 26. Therefore, the outside air that enters through the eaves is heated and rises in the ventilation groove, and is exhausted to the outside from the ridge, so that the temperature in the attic can be automatically adjusted.

In the above explanation, the present invention was applied to the reroofing of all existing cliff edges, but it can also be applied to newly constructed buildings, and by making some changes, it can also be applied to the renovation of external walls.

〔Effect of the invention〕

As is clear from the above description, according to the roof re-roofing method according to the present invention, the following remarkable effects can be obtained.

(1) According to the present invention, since a base material with excellent insulation performance is used, the insulation effect can be increased, and since air flows inside the roof, heat accumulation in the attic is prevented, and the indoor temperature is reduced. The rise can be prevented.

(2) The energy received on the roof surface is gradually stored in the base material, but since ventilation grooves are provided on the underside of the base material, the outside air that enters from the eaves absorbs heat in the ventilation grooves and is transferred from the ridge. be discharged. Therefore, there is no heat storage in the base material, so there is no heat conduction to the ceiling.

(3) Ventilation grooves are provided in the base material to allow outside air to circulate, so even in the winter, the front and back surfaces of the roofing material can absorb the temperature of the outside air.
Humidity is the same condition. Therefore, occurrence of dew condensation can be prevented.

(4) We created a well-balanced temperature distribution over the entire ridge with a simple structure using ventilation grooves in the base material, without relying on electrical or mechanical methods, so ice blocks do not form on the eaves.
This can prevent leakage.

(5) Conventional ventilation systems are expensive because they use aluminum profiles and sophisticated mechanisms, but the present invention uses foundation materials and commercially available corrugated sheets and metal sheets, and is adjusted to the dimensions of the building on site. Since it is simply processed and attached, it is extremely inexpensive and can be implemented using simple technology.
