Description

[Detailed description of the invention] The present invention relates to roofing materials.

More specifically, it relates to a roofing material that is mainly used on the roofs of house balconies, terraces, power boats, etc., and whose purpose is to prevent rainwater, let in natural light, or adjust the amount of transmitted light. Conventionally, corrugated sheets made of pinyl chloride resin or glass fiber reinforced synthetic resin have been used as roofing materials for balconies, terraces, carports, etc.

However, the above-mentioned conventional roofing materials have various drawbacks.

That is, rainwater first separates and flows into the recesses of the corrugated sheet, and since the flow rate is small, dirt tends to accumulate on the surface of the recesses of the corrugated sheet.
When fixing corrugated sheet roofing materials to the beam main building, at least two corrugations were overlapped and hook bolts were inserted to secure the corrugated sheet roofing material. Dirt penetrates into the overlapped parts of the materials and accumulates, and the rust from the hook bolts washes away, further staining the surface of the roofing material, resulting in a significant deterioration in its aesthetic appearance.

In addition, the corrugated sheet roofing material of the substructure was insufficiently rigid, and had the disadvantage of making flapping noises when blown by the wind.

In order to prevent this, it is necessary to use a large number of fixing devices such as hook bolts to firmly fix it to the crosspiece or beam.
Inserting a fixed odor such as a hook bolt has the above-mentioned disadvantages, and the possibility of leakage from the insertion hole of the fixing device increases, and the amount of work required to tighten the fixed odor at a high place increases, which is dangerous. At the same time, the complexity of construction increases. The present invention solves the above-mentioned conventional drawbacks, and has an excellent appearance without the accumulation of dirt on the surface due to rainwater, dirt, dust, etc., and at least the parts to be fixed to the crosspieces or beams are firmly fixed, and the rigidity is improved. The object of the present invention is to provide a roofing material that does not make a flapping sound even when it is blown by the wind because of its large size. Next, an example of the present invention will be explained with reference to the drawings. 1st
The figure shows the side profile of an example of the roofing material of the present invention. The plate-shaped body 1 has a central portion projecting upward in an arch shape, and is formed into a double structure in which a large number of reinforcing connecting plates 2 are provided. Slanted slope portions 3, 3 are provided obliquely upward from both side edges of the plate-like body 1. The inclined slope portions 3, 3 are curved so that the side end surfaces thereof face sideways. The roofing material of the present invention is made of, for example, a polyvinyl chloride resin and is extruded into a profile, and is made entirely transparent or translucent to allow daylight to enter.

In FIG. 1, a locking protrusion 4 having a sliding door-shaped tip is provided from the side end surface of the left sloped slope 3, and a locking recess 5 is provided in the side end surface of the right sloped slope 3 which is initially opened.

The locking recess 5 has a protrusion facing toward the inner part of the opening □, so that the locking protrusion 4 can be locked, and once locked, it is prevented from coming off. The sun stop protrusion 4 and the sun stop recess 5 are provided along the entire length of the roof material in the longitudinal direction. Gutter grooves 6, 6 are formed on both green parts of the plate-shaped body 1 by the inclined surfaces of the plate-shaped body 1 and the inclined plate parts 3, 3.

Furthermore, horizontal plates 7, 7 are provided on the back surfaces of both side edges of the plate-like body 1, and substantially parallel narrow insertion grooves 8, 8 are formed therein. FIGS. 2 to 4 also show other examples of the roofing material of the present invention.

The plate-like body lb in FIG. 2 has a double structure, with the central portion protruding upward and forming a shape in cross section. In Figure 3, the plate-like body l
C also has a double structure, with the center portion protruding upward and being approximately trapezoidal. In the roofing material shown in FIG. 4, the plate-shaped body ld is provided with two upwardly protruding parts. A gutter groove 6d' is formed between the upwardly protruding parts of the plate-like body ld,
A closed insertion groove 8d' is provided on the back surface. The fact that the plate-shaped body 1 has a cross-sectional shape that protrudes upward improves the rigidity of the entire roofing material, eliminates areas that deform due to wind and loads from above, and causes flapping noises caused by the wind. Not at all.

In addition, the strength of structures such as carports on which the roofing material is installed is also improved. When these roofing materials are fixed to crosspieces, beams, and main buildings, the plate-shaped body 1 also expands and contracts in the middle direction due to the difference in temperature between summer and winter.

With conventional corrugated roofing materials, when there is expansion and contraction, the overlap between adjacent roofing materials makes it impossible to absorb the large amount of expansion and contraction, which can lead to damage. With the roofing material of the present invention, even if both side twill parts of the plate-like body 1 are fixed, because the center part of the plate-like body 1 is shaped to protrude upward, the center part will not expand or contract slightly up and down. Absorb.
4 In the roofing material of the present invention, most of the rainwater is received by the plate-like body 1, but the rainwater is collected in the gutter grooves 6, 6 on the green parts on both sides of the plate-like body 1, and the upper surface of the plate-like body 1 is Dirt does not stick and is washed away. In the gutter grooves 6, 6, the rainwater collected from the plate-shaped body 1 has a certain amount of flow rate and velocity, and is flushed away without collecting dirt and dust.
It does not become dirty and deteriorate the aesthetic appearance of the roofing material.

In the roofing material of the present invention, the locking protrusion 4 provided at the side end of one inclined plate part 3 is connected to the locking protrusion 4 provided at the side edge part of the other inclined plate part 3 in another adjacent roofing material. They can be competitively locked in the locking recess 5 and connected to each other.

When the locking protrusion 4 is iron-fitted to the locking recess 5, the connection is made by the elasticity of the protrusion facing the protrusion at the opening of the locking recess 5, or by shortening the length of the locking protrusion by 4 mm. Although no gaps or grooves are formed in the part, sealing material is provided at the side edges of the slope parts 3, 3,
A sealant is attached to the connecting part of the locking protrusion 4 and the locking recess 5,
It may be arranged so that no gaps or grooves are formed. The state in which several roofing materials are connected is shown in FIG. The detailed state of the joints between the roofing materials is shown in FIGS. 6 and 7.
The locking protrusion 4 of one inclined plate part 3 competes with the locking recess 5 of the other inclined plate part 3, and the tip of the mark of the locking protrusion 4 is located at the back of the opening of the locking recess 5. The protrusions oriented in this direction are locked to prevent the locking protrusion 4 from slipping out of the locking recess 5. A locking protrusion 4 is provided outward from the side end,
Since the locking recess 5 is open and provided on the side end face of the inclined slope part 3, even the largest roofing material can be easily connected by bringing the inclined plate parts 3 together and sandwiching them. Since the joint between the roof panels is located at the apex of the small arch formed by the inclined plate parts 3, 3, rain leakage can be prevented if the joints are firmly connected.

In conventional corrugated roofing materials, at least two of the adjacent roofing materials
The corrugated parts of the mountains were overlapped and connected, but rainwater penetrates into the overlapped part along with dirt and dust by capillary action, and even rainwater leaks and dirt accumulates.
Since the roof panels are connected to each other by the locking of the locking recess 5, dirt does not accumulate in the connecting portion. Furthermore, connecting the side edges of the roof panels without overlapping them saves on materials, and when used for daylighting, there is no extreme shading in brightness, resulting in favorable daylighting. By connecting the roofing materials together, a pair of opposing insertion holes 8, 8 is formed below the connecting portion.

This pair of insertion grooves 8, 8 is formed in a fixed part of the roof panel. How the roofing material is fixed to the crosspieces, beams, and main building is shown in FIGS. 6 to 8. 9 is a main building made of C-shaped steel, which is connected to pillars of a veranda, terrace, carport, etc. On the purlin 9, both sides of the fixing plate 10 are inserted into the insertion grooves 8, 8, and the fixing plate 10 and the purlin 9 are tightened by a fixture 11. Insertion grooves 8, 8 on the back of the roofing material and fixing plate 10'
Therefore, by fixing to the main building 9, it is possible to avoid providing a fixing odor insertion hole in the roofing material itself, and the work of fixing the roofing material can be done from below the roofing material, which facilitates construction.
To insert the fixing plate 10 into the insertion grooves 8, 8 of the roofing material, as shown in FIG. This can be done by rotating.

By fixing the roof material plate 1 to the main building 9 at both side traverses, twisting and distortion of the green parts on both sides of the plate 1 are eliminated, and there is no deformation due to wind or load. Since both roofing materials are fixed to the main building 9 below the connecting portion between the roofing materials, the connecting portion between the roofing materials is prevented from coming off due to external force such as wind blowing.

In the above example, the horizontal plate 7 and the insertion groove 8, which are the fixing parts of the roofing material, are provided on the back side of the green parts on both sides of the plate-like body 1, but the locking grooves and locking ridges are provided on the sloped slope part. It may also be provided on the back side of 3 and 3.

However, if the roofing materials are stacked before construction, they should be placed on the back side of the green areas on both sides of the plate-like body 1, where the thickness can be made the thickest, rather than on the sloped slope parts 3, 3, where the thickness is the thinnest. This allows for the best stacking of items, which allows for a smaller packaging volume. FIG. 10 shows a fixing plate 10 and a fixture 11. As shown in FIG.

Both ends of the fixed plate 11 are bent to form steps that sandwich the horizontal plates 7, 7. A nut 12 is integrally provided on the fixed plate 101. 13 is a washer, which is used together with the bolt-like fixture 11.

FIG. 11 shows another example of the fixing plate 10a.

One plate body la' is rotatably fixed to the fixed plate la. As described above, the roofing material of the present invention can be used for the roofs of balconies, terraces, carports, etc. as a high-quality roofing material that eliminates the drawbacks of conventional roofing materials. The roofing material of the present invention has sloped plate parts diagonally upward from both side edges of the plate-like body which is inclined from the top of the central part toward the green parts on both sides and has increased rigidity, so that the roofing material can be used as a whole. This increases rigidity and prevents it from deforming due to wind or external forces, and from making flapping noises when it is fanned by the wind. A locking protrusion is provided at the side end of one of the inclined plate parts, and a locking recess into which the locking protrusion can be locked is provided at the side end of the other inclined plate part. When connecting the roofing materials, the side edges of the roofing materials can be connected without overlapping each other, preventing the adhesion of dirt due to the penetration of rainwater, saving materials, and maintaining a favorable lighting condition.

In addition, since the locking protrusion is provided outward from the side end of the inclined plate part, and the locking recess is provided to open on the side end surface of the inclined plate part, the slope of the adjacent roofing material can be adjusted. Even long roofing materials can be easily connected by placing the board sections together and sandwiching them together.

Furthermore, rainwater that falls onto the plate-shaped body that slopes from the top of the central part toward both side edges is collected in the gutter groove formed by the plate-shaped body and the sloped surface of the sloped plate part, and is collected by the plate-shaped body. The upper surface of the rainwater drains without dirt adhering to it, and the gutter provides sufficient flow rate and velocity of rainwater, allowing dirt and dust to flow out without accumulating.

Since the connecting part between the roofing materials is located at the top of the inclined plate part,
Penetration and leakage of rainwater can be prevented by locking the locking protrusion and the locking recess.
