Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a horizontal roof structure.

(Prior art) In general, the horizontal roof structure of a building is constructed by arranging a plurality of horizontal roofing materials in steps to cover the roof of the building, and engaging the upper and lower folded ends of each of the upper and lower roofing materials. In addition to stopping and connecting,
The above-mentioned roofing material is constructed by fixing a hanger that locks the upper folded part on the rafters, but conventional roofing materials make noise when it rains and also create gaps between the top surface of the rafters and the roofing material. Therefore, if a person steps on the roofing material or other external forces are applied, the roofing material may cave in, be damaged, or deform.Furthermore, there are disadvantages such as condensation forming on the back side of the roofing material. there were.

(Technical Problem of the Invention) The technical problem of the present invention is to propose a horizontal roof structure with great heat insulation and soundproofing effects.

Further, the technical object of the present invention is to propose a horizontal roof structure that has high heat insulation and soundproofing effects and is also high in strength.

(Means for Solving the Problems) In order to solve the first problem described above, the present invention provides a plurality of horizontal roofing materials that cover the roof of a building, arranged in steps, and each of the upper and lower roofing materials In a horizontal roof structure in which the upper and lower edges of the roofing material are folded back and the folded parts are locked and connected, and a hanger that locks the upper end folded part of the roofing material is fixed on the rafters, the back side of the roofing material is at least insulated. It is characterized by being made of a synthetic resin material that has properties.

In addition, in order to solve the second problem described above, the present invention arranges a plurality of horizontal roofing materials in a stepped manner to cover the roof of a building,
In the horizontal roof structure in which the upper and lower edges of each of the upper and lower roofing materials are folded back, the folded portions are locked and connected, and a hanger that locks the upper end folded portion of the roofing material is fixed on the rafters. The present invention is characterized in that the hangers are arranged along the back side of the roofing material, and a synthetic resin material having at least heat insulating properties is interposed between the hangers and the roofing material.

(Operations and Effects of the Invention) As described above, according to the present invention, since the synthetic resin material having at least heat insulating properties is provided on the back side of the roofing material, dew condensation on the roofing material is prevented. Synthetic resin materials such as these usually also have a soundproofing effect, so they can muffle annoying sounds such as the sound of rain, making it more comfortable to use.

In addition to installing a heat-insulating synthetic resin material on the back side of the roofing material,
According to the configuration in which the hangers are arranged along the back surface of the roofing material, in addition to the above-mentioned heat insulation and soundproofing effects, the roofing material is reinforced from the back side by the hangers, making it possible to obtain a roof with high strength. Therefore, no separate back-up material or the like is required, and the number of work steps can be reduced.

(Example) Hereinafter, the horizontal roof structure according to the present invention will be explained.

FIGS. 1 and 2 show an embodiment of the present invention, and reference numeral 3 indicates a hanger. This hanger 3 is a horizontal roofing material 1, l that is continuously laid from the bottom (left side of the drawing) to the top (right side of the drawing).

The hanger 3, which extends downward (rearward) from the connecting part of . Base part 3a placed and nailed along the rafter 2
, a front inclined plate 3b rising forward and upward at a predetermined angle from the front end side (upper end side) of the base portion 3a, and a locking member extending further forward and upward at a predetermined angle from the tip of the front inclined plate 3b. It has a stop part 3c. The tip of the locking portion 3c is a folded portion 3d that is folded back downward, and the locking portion 3c and the folded portion 3d constitute an engaging portion 4. A rear inclined plate 3e extends rearward and upward from the rear end side of the base portion 3a at a predetermined angle, and from the upper end of the rear inclined plate 3e extends rearward and slightly downward a reinforcing portion having a recess 5.5. 3f is extended, and the rear end of this corrugated reinforcing portion 3f is bent downward to become a rear end plate 3g, and further the rear end plate 3g
The lower end of the nail plate 3h is bent backward. The upper end portion of the locking portion 3C is configured to be located on an extension of the upper surface of the reinforcing portion 3f. It is preferable that the nailing board 3h and the base portion 3a are located on the same plane.

The base portion 3a and the nailing board 3h are fixed to the rafter 2 with nails or the like.

Next, a planar member 20 made of synthetic resin is attached to the surface of the hanger having the above structure by adhesive or the like. The synthetic resin material 20 may have the same size as the hanger, but it is preferably formed to have approximately the same width as the roofing material, and should have at least a heat insulating property, especially if it is made of urethane resin, etc. It is preferable to use materials with high performance and soundproofing properties.

On the other hand, the roof material 1 installed on the rafters 2 is composed of a long belt-shaped metal plate of a constant width, and has folded parts 1a on the upper and lower edges,
lb is formed, and the upper and lower edge folded parts 1 of each of the upper and lower roofing materials
a and lb are locked and connected to each other. In addition, 21
is an asphalt true swing installed on rafter 2.

In the above configuration, when connecting the roofing material 1.1Φ fist, the engaging part 4 of the hanger 3 is engaged from above the rear folded part 1b of the upper roofing material 1, and in this state, the hanger 3 is connected. Place the base part 3a and nailing board 3h on the top surface of the rafter 2.
Fasten by nailing. Next, the front folded portion 1a of the lower roof material 1 is engaged with the outside of the engaging portion 4 of the hanger 3.

Each edge folded portion 1a of such a hanger 3 and roof material 1.1
, lb, the roofing materials 1 and 1 are firmly and reliably connected. In addition, since the reinforcing part 3f of the hanger 3 backs up the back surface of the roofing material 1 while being in contact with it, the roofing material 1 is reinforced by the reinforcing part 3f due to external force from above, causing deformation, damage, etc. There is no fear of

In addition, since the insulating synthetic resin material 20 is interposed between the back side of the roofing material 1 and the hanger 3, indoor temperature is difficult to be transmitted to the roofing material 1. Condensation on 1 is prevented. Moreover, since the synthetic resin material 20 which has a heat insulating property also has a sound proofing property, annoying sounds such as rain sounds are muffled, and it is comfortable even when it rains.

Next, FIG. 3 shows another embodiment of the present invention.

The same parts as in FIG. 1 are indicated by the same reference numerals, and redundant explanation will be omitted. In this hanger 30, the tip of the locking part 3c hangs downward at a substantially right angle to form a folded part 30d.
An engaging portion 40 is constituted by the locking portion 3C and the folded portion 30d.

Further, the front folded portion 1a of the roof material 1 hangs down at a substantially right angle along the folded portion 30d, and the tips of the hanging pieces are bent rearward, and these constitute the folded portion 10a.

The rear edge is a first folded part 10b folded back in the front direction.
, a second folded part 10c which is obtained by folding back the tip of the folded part 10b further backward, and a nailing part 10d which is extended rearward after the second folded part 10c is suspended.

In the above configuration, by engaging the first and second folded parts 10b and 10c of the roofing material l inside the engaging part 40 and engaging the folded edge part 10a outside the engaging part 40, Assembly is performed.

In this case, the same heat insulation, sound insulation, and reinforcing effects as in the example shown in FIG. 1 can be obtained, and since the nailing portions 10d of each roofing material 1 are fixed to the rafters 2, the installation strength is greatly increased.

Note that the hanger does not necessarily need to be provided through the back surface of the roofing material, and may be provided on the rafters as in the past. In this case, the heat insulating synthetic resin material 20 may be attached to the entire or part of the back side of the roof material.
