Description

The present invention relates to an improvement in the rooftop structure of a building.

Waterproof panels are generally laid on the roof of a building. Moreover, on the rooftop of a building, especially in a high-rise building, a considerably strong wind is generated even in a normal time. And even in the event of a typhoon, it is necessary to prevent the laid waterproof panel from peeling off. Further, the panel itself is required to be inexpensive and easy to construct.

As a rooftop structure of a conventional building, for example, there is one disclosed in Japanese Patent Application Laid-Open No. 3-87467. The outline thereof will be described with reference to FIG. 13. The panel 1a is provided with a heat insulating material 4 between the front surface material 2 and the back surface material 3. The joints 9 of the panel 1a have a complicated shape in which they are engaged with each other in a dovetail shape. Further, the joint cover attachments 5 are fixed with screws 7, and the joints 9 are filled with caulking material for the purpose of sealing, and the panel 1a is spread and fixed to the floor of the building roof with anchor bolts 8. The joint cover 6 is fitted to the joint cover attachment 5.

Further, as another conventional example, there is one disclosed in Japanese Patent Application Laid-Open No. 9-279713. The outline thereof will be described with reference to FIG. 14. The surface material 2 of the panel 1b has an uneven surface formed so that the board 11 can be hung and the head of the anchor bolt 8 can be inserted. Further, in order to maintain the fixing force of the anchor bolt 8, the core material 13 is embedded in the heat insulating material 4 in the uneven surface portion. Then, first, the joint plate 14 is fixed to the roof floor surface 10 with anchor bolts 15, then the panel 1b is laid along with the joint plate 14, the joints 9 are filled with a sealing material, and the panel 1b is attached with anchor bolts 8. It is fixed to the roof floor surface 10. Next, the board 11 provided with the joint cover attachments 5 at both ends is fixed to the roof floor surface 10 with anchor bolts 12 so as to hang over the steps of the panel 1b, and the joint cover 6 is attached to the joint cover attachments. I try to fit it in 5.

Next, in the conventional example shown in FIG. 15, the corner panel 17 provided between the roof floor surface 10 and the vertical wall 16 has a small radius of curvature of approximately 90 degrees so as to run from the roof floor surface 10 to the vertical wall 16.

In each of the above-mentioned conventional examples, the shape of the portion forming the joint of the panel is complicated, and particularly in the conventional example shown in FIG. 130, the joint portion is engaged between a female and a male. There is a problem that the mold for panel molding is complicated and two types of molds are required, resulting in an expensive panel. In addition, when a panel with such a complicated shape is made into a standardized quadrilateral panel and laid on the roof floor, the joints where the corners of the four panels are butted against each other become complicated. It is virtually impossible to stylize into a quadrilateral panel. Therefore, there is a problem that the panel itself becomes large, it becomes difficult to mass-produce it, and the panel becomes expensive.

In addition, in actual construction, there is a problem that the number of parts such as joint cover, joint cover attachment, many anchor bolts, filling of sealing material increases, the construction man-hours increase, and the building roof structure becomes expensive. is there. Further, in the conventional example shown in FIG. 11, the joint plate 14 must be fixed first with the anchor bolt 15. Therefore, if the position of the joint plate 15 is incorrect, the concrete of the roof floor surface 10 is hung, the anchor bolt 15 is pulled out, the hung part is backfilled, and the anchor bolt is put back in the proper position. It is necessary to re-strike 15 and there is a problem in terms of workability.

Next, in the conventional example shown in FIG. 15, when the wind in the direction of arrow B or C blows, a vortex as shown by the arrow is generated in the corner portion. Then, the corner portion D becomes a negative pressure. Due to this negative pressure, a force F acts on the corner panel 17 in the direction of peeling from the vertical wall 16. Since the corner panel 17 is bent at a substantially right angle with a small radius of curvature, the corner panel 17 provided along the vertical wall 16 is likely to bend in the force F direction, and there is a high possibility that this portion will peel off. There is a problem. Then, once the corner panel 17 is peeled off, there is a problem that the entire corner panel 17 is peeled off, and finally the panel 1 on the roof floor surface 10 is also peeled off.

As a rooftop structure of a building using a panel that solves the problem of the panel, there is one disclosed in Japanese Patent Application Laid-Open No. 2001-0270117. By simplifying the shape of the panel, it enables inexpensive mass production, forms a pyramidal convex panel surface, and makes the rooftop surface on which the panel is laid uneven, and the wind is strong.

Further, a large number of protrusions are formed on the back surface of the panel, and by forming many ventilation layers with the floor surface of the roof, moisture-containing air evaporating from the concrete on the floor surface of the building roof. It has an excellent effect of releasing the air and preventing the panel from swelling due to the water vapor pressure.
However, the panel disclosed in Japanese Patent Application Laid-Open No. 2001-0270117 has a problem that water leakage from gaps between fixing members and holding members cannot be sufficiently prevented, and further has a problem that it is easily destroyed by an earthquake. is there.

Further, although the panel disclosed in Japanese Patent Application Laid-Open No. 2001-0270117 can construct a stable structure by driving an anchor bolt and pressing it with a pressing plate, it is not possible to sufficiently prevent water leakage. Furthermore, after a long period of time, the outer peripheral edge of the panel was wavy and raised due to the unevenness of the concrete on the roof of the building, and a gap was created between the panel and the anchor bolt holding plate, resulting in a problem that the stability of the panel was impaired. .. Further, although the panel has sufficient strength, it is desired that the strength is further improved.

Next, Reference Invention 1 and Reference Invention 2 using the fixing member will be described.
In FIG. 8, the fixing member 26 is composed of two members 26a and 26b, and by fitting the notch 26d, the fixing member 26 becomes a cross-shaped fixing member 26. As described above, the reason why the two members 26a and 26b are used is that the fixing member 26 can be easily processed and is suitable for mass production, and when the fixing member 26 is disassembled, the two rod-shaped members 26a are used. This is to reduce the storage space of the warehouse and the transportation space to the site. Further, the members 26a and 26b use a U-shaped material and form an air passage between the members 26a and 26b and the roof floor surface 10. Then, although not shown in the figure, the portion where the pressing plate 28 comes into contact is recessed by the thickness of the pressing plate 28 to make the two surfaces coincide with each other, eliminate the floating of the sheet material 30 to be attached, and adhere to the sheet material 30. Try to improve your sex. Reference numeral 26c is a hole for inserting the anchor bolt 27, which is formed so as to be located at the center of the cross.

Further, as shown in FIG. 9, a cross-shaped fixing member 26 is provided, and as shown in FIG. 8, the cross of the fixing member 26 is laid along the side side of the panel 18, and an anchor is placed at the center of the fixing member 26. Since the bolts 27 are driven in and the corners of the flange portions 19 of the four panels 18 are fixed by the pressing plate 28 pressed by the driving force of the anchor bolts 27, the stylized panels 18 can be fixed. That is, the panel 18 can be standardized into a panel 18 having a quadrangular shape and a flat and simple flange 19. Then, as shown in FIG. 6, there is no fitting portion or filling of the sealing material between the side surface of the panel 18 and the side surface of the fixing member 26, and both side surfaces may be brought into contact with each other. The panel 18 can be positioned before the 26 is fixed to the roof floor with the anchor bolts 27. As a result, it is possible to prevent the occurrence of poor positioning, eliminate extra work such as re-fixing the fixing member 26, and reduce the number of anchor bolts 27.

Then, as shown in FIG. 5, by sticking the sheet material 30 on the flange portion 19, the fixing member 26, and the pressing member 28 of the paved panel 18, the seal is secured and the construction work is facilitated. can do. Further, since the members 26a and 26b of the fixing member 26 are short, a gap corresponding to the width of the members 26a and 26b is formed in the joint portions of the panels 18 each other without the fixing member 26. Then, since the sheet material 30 is attached so as to close the gap and the members 26a and 26b use U-shaped members to allow air to flow, the gap becomes an air passage. By letting air containing moisture that evaporates from the concrete on the floor surface 10 of the roof escape, it is possible to prevent the panel 18 from swelling due to the vapor pressure.

Next, a construction example of the corner portion of the roof will be described with reference to FIG. 10, and a construction example and operation of the air outlet portion will be described with reference to FIGS. 11 and 12.
In FIG. 10, the corner panel 31 is provided with a constant radius of curvature R from the roof floor surface 10 to the vertical wall 16. The radius of curvature R is theoretically determined by the height H1 of the building, the height H2 of the vertical wall 16, and the strength of the wind. However, when the radius of curvature R is theoretically determined, the radius of curvature is uniquely determined, but the basic idea of this determination is to rectify the wind in the direction of arrow B or C as indicated by the arrow. Since it is to reduce the negative pressure in the corner, it is not limited to the unique radius of curvature R obtained theoretically, but in short, there is an allowable range based on the radius R of curvature obtained theoretically. , The radius of curvature that rectifies the flow of wind may be used. As shown in FIG. 3, when the stylized panel 18 is laid on the floor surface 10 of the roof, the area of the floor surface 10 is not constant, so that an odd portion is generated. That is, in FIG. 7, since the dimension L1 when the panels 18 are laid on the floor surface 10 in order is constant according to the dimension of the stylized panel 18, the dimension of L2 is changed due to the variation in the area of the floor surface 10. Not constant.

At that time, the floor surface 10 side of the corner panel 31 is cut and adjusted so as to have the dimension L2. This makes it possible to use the stylized panel 18. That is, the panel 18 can be stylized. Further, in order to secure the strength against peeling of the corner panel 31, the anchor bolt 27 may be driven in. In this case, since the member 26a of the fixing member 26 serves to reinforce the corner panel 31, the peeling of the corner panel 31 can be further suppressed. Further, a cutting line is formed in the heat insulating layer 25 so that the corner panel 31 can be easily bent at the site so that the heat insulating layer 25 is separated from the cutting line as shown in the figure.

As shown in FIG. 10, a corner panel 31 bent to a predetermined radius of curvature R is provided over the floor surface 10 of the building roof and the vertical wall 16, and the radius of curvature R is the height H1 of the building and the height of the vertical wall 16. It is theoretically determined by H2 and wind velocity, and the flow of wind is rectified as shown by arrows B or C. Therefore, the negative pressure generated in the corners is reduced and the bending radius R is increased to increase the bending direction (force). The bending strength of the corner panel 31 in the F direction) can be increased, and peeling of the corner panel 31 can be suppressed.

In FIGS. 11 and 12, the air outlet 33 of the corner panel 31 is tapered by bending the end of the eaves 34 and the tip of the corner panel 31 so that air is normally discharged as shown by an arrow A. The corner panel 31 is prevented from peeling off by preventing the air from flowing back from the air outlet 33 in a typhoon or the like. Further, the anchor bolt 27 is driven into the air outlet 33 side of the corner panel 31 with the U-shaped contact member 32 interposed therebetween so that the air can flow, so that the corner panel 31 can be more reliably prevented from peeling off. It may be.

Although not shown, the heat-shielding paint is applied to the exposed surface of the paved panel and the exposed surface of the vibration absorber or the reinforcing material provided as needed.

The operation of this embodiment configured as described above will be described below. As shown in FIG. 3, a quadrilateral panel 18 is laid on the roof floor surface 10 of the building, a continuous reinforcing convex portion 40 is provided on the entire outer peripheral edge of the flange portion 19, and the corner portions of the flat flange portions 19 are reinforced. By fixing the panel 18 from above the convex portion 40 with one pressing plate 28, the panel 18 can be made into a simple shape. Then, as shown in FIG. 1, by forming flat flange portions 19 having a constant width on the four sides of the panel 18, the shape of the panel 18 can be simplified, and the outer peripheral edge of the flange portion 19 is continuously reinforced. By providing the convex portion 40 to improve the strength, even after a long period of time has passed since the roof structure was constructed, the outer peripheral edge of the panel undulates and rises, and a gap is created between the anchor bolt and the holding plate to stabilize the panel. Is prevented from being impaired. Further, by pressing the reinforcing convex portion 40 with the pressing plate 28, the force is concentrated on the reinforcing convex portion 40, so that the reinforcing convex portion 40 can further efficiently press the flange portion 19, which is also stable from this point. Improves sex.

Further, by forming a pyramidal convex panel surface 20 formed by the ridge line 23 by raising from the flange portion 19 at a predetermined inclination angle, the rooftop surface on which the panel 18 is laid becomes an uneven surface, and the rooftop is blown. The resistance of the flowing wind can be increased to soften the strength of the wind. The panel 18 has a simple structure in which a heat insulating layer 25 made of foamed resin is provided on the back surface of the skin 24 made of hard resin.

As shown in FIGS. 6 and 7, a flat reinforcing flange portion 36 following the step portion 36a is provided below the panel surface 20, and is formed as a drainage panel surface 35 on a steep downhill below the reinforcing flange portion 36. Therefore, the recess formed by the drainage panel surface 35 and the flange portion 19 acts as a drainage groove, so that rainwater can easily flow without being accumulated. Further, the strength of the panel is improved by providing the reinforcing flange portion 36.

As shown in FIG. 6, the reinforcing material 37 is provided over the entire rooftop structure of the building from the drainage panel surface 20a to the drainage panel surface 20b so as to cover the entire adjacent flange portions 19a and 19b. Compared with the structure in which the sheet material 28 appears on the surface of the rooftop structure, joints between flanges, gaps between holding members, and water leakage from fixing members are more reliably prevented.

As shown in FIG. 7, a reinforcing material 37 is provided over the entire rooftop structure of the building from the drainage panel surface 20a to the drainage panel surface 20b so as to cover the entire adjacent flange portions 19a and 19b. Since the reinforcing material 37 is covered with the vibration absorbing material 38 over the entire roof structure, water leakage from the gaps between the fixing member and the holding member is more reliably prevented, and vibration occurs even in the event of a larger earthquake. Since the absorbent 38 absorbs the shaking of the earthquake, it is possible to effectively prevent the destruction of individual panels and the entire rooftop structure of the building.

Further, as shown in FIG. 3, a panel 18 formed into a substantially square shape is laid down, the panel 18 is raised from the flange portion 19, the upper surface of the roof is made uneven, and the resistance of the wind blowing on the roof is increased to increase the wind. By weakening the strength (wind pressure) of the corner panel 31 and increasing the rectifying effect of the corner panel 31 and the bending strength in the peeling direction, the corner panel 31 can be prevented from peeling more reliably, and thus the rooftop. It is also possible to prevent peeling of the entire panel 18 stretched on the flange.

Further, as shown in FIG. 3, the rooftop structure of the building using the panel is facilitated by fixing the portion where the reinforcing convex portion of the corner or side of the panel is formed by using the anchor bolt 27 and the holding plate 28. The completed rooftop structure can be constructed in a stable manner for a long period of time.

Although not shown, the entire rooftop structure of the building is coated with a heat-shielding paint, which suppresses deterioration due to ultraviolet rays and greatly extends the usable life.
