Description

  The present invention relates to an improvement of a roof structure of a building.

  A waterproof panel is generally placed on the roof of a building. On the roof of a building, particularly on a high-rise building, a considerably strong wind is generated even during normal times. And even during a typhoon, it is necessary to prevent the waterproof panels laid out from peeling off. Furthermore, the panel itself is required to be inexpensive and easy to construct.

  As a conventional rooftop structure of a building, for example, there is one disclosed in JP-A-3-87467. The outline will be described with reference to FIG. 13. The panel 1 a is provided with a heat insulating material 4 between a front surface material 2 and a back surface material 3. And the part of the joint 9 of the panel 1a has a complicated shape engaged with each other in a dovetail shape. Further, the joint cover mounting tool 5 is fixed with screws 7 respectively, and the panel 9a is laid and fixed to the floor surface of the building roof with the anchor bolt 8 while filling the joint 9 with a caulking material for the purpose of sealing. The joint cover 6 is fitted to the joint cover attachment 5.

  Another conventional example is disclosed in Japanese Patent Laid-Open No. 9-279713. The outline thereof will be described with reference to FIG. 14. The surface material 2 of the panel 1 b has an uneven surface so that the board 11 can be passed over and the head of the anchor bolt 8 is inserted. In addition, a core material 13 is embedded in the heat insulating material 4 in order to maintain the fixing force of the anchor bolt 8 in the uneven surface portion. First, the joint plate 14 is fixed to the roof floor 10 with the anchor bolt 15, and then the panel 1 b is laid along with the joint plate 14, the joint 9 is filled with the sealing material, and the anchor bolt 8 is used to attach the panel 1 b. Fix to the rooftop floor 10. Next, the board 11 provided with joint cover attachments 5 at both ends is fixed to the rooftop 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. 5 is fitted.

  Next, in the conventional example shown in FIG. 15, the corner panel 17 provided between the rooftop floor surface 10 and the vertical wall 16 is approximately 90 degrees with a small curvature radius so as to extend from the rooftop floor surface 10 to the vertical wall 16. It is bent. And as shown by the arrow A, air escapes.

  In any of the above conventional examples, the shape of the portion forming the joint of the panel is complicated. In particular, in the conventional example shown in FIG. 130, the joint portion is engaged with the female and male. The panel molding die is complicated, and two types of molds are required, resulting in an expensive panel. In addition, when the panel with such a complicated shape is made into a quadrangular shaped panel and laid on the rooftop floor surface, the joint part where the corners of the four panels abut each other becomes complicated, It is impossible to form a substantially quadrilateral panel. For this reason, the panel itself becomes large and difficult to mass-produce, resulting in an expensive panel.

  In actual construction, the number of parts such as joint covers, joint cover fittings, a large number of anchor bolts, and filling of sealing materials increases, which increases the number of construction steps and makes the building rooftop structure expensive. is there. 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 inaccurate, the concrete of the rooftop floor surface 10 is hung, the anchor bolt 15 is pulled out, the hooked portion is backfilled, and the anchor bolt is re-positioned to the proper position. Work such as reworking 15 is required, and there is a problem in terms of workability.

  Next, in the conventional example shown in FIG. 15, when a wind in the direction of arrow B or C blows, a vortex as shown by an arrow is generated at the corner. And the corner part 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 easy to bend in the direction of force F, and there is a high possibility that this portion will peel off. There is a problem. And once the corner panel 17 peels, the corner panel 17 whole peels, and the panel 1 of the rooftop floor surface 10 finally peels.

Japanese Laid-Open Patent Publication No. 2001-027017 discloses a rooftop structure of a building using a panel that solves the problems of the panel. This simplifies the shape of the panel, enables mass production at low cost, forms a pyramid-shaped convex panel surface, and makes the rooftop surface with the panel rugged, creating a strong wind. By reducing the thickness, peeling of the corner panel due to wind can be prevented, and the panel has a simple structure in which a heat insulating layer made of foamed resin is provided on the back surface of the skin made of hard resin. be able to. In addition, a large number of protrusions are formed on the back surface of the panel, and air containing moisture evaporating from the concrete on the floor surface of the building roof is formed by forming a large number of ventilation layers between the roof surface and the roof surface. It has an excellent effect of escaping and preventing swelling of the panel due to water vapor pressure.
However, the panel disclosed in Japanese Patent Laid-Open No. 2001-027017 has a problem that water leakage from the gap between the fixing member and the pressing member cannot be sufficiently prevented, and further has a problem that it is easily broken by an earthquake. is there.

  Furthermore, although the panel disclosed in Japanese Patent Application Laid-Open No. 2001-027017 can construct a stable structure by driving an anchor bolt and pressing it with a pressing plate, it cannot sufficiently prevent water leakage. Furthermore, after a long period of time, the outer periphery of the panel undulated due to the unevenness of the concrete on the roof of the building, causing a problem that the stability of the panel was impaired due to a gap between the anchor bolt and the presser plate. . Further, although the panel has a sufficient strength, it is desired that the strength is further improved.

  The present invention simplifies the shape of the panel and makes it easy to construct even a standardized panel, enabling mass production, making the panel inexpensive, reducing the number of construction steps, and at the corners. It can prevent peeling and sufficiently prevent water leakage from the gap between the fixing member and the holding member, and is hard to be destroyed by an earthquake. However, it is intended to provide a rooftop structure of a building that has an outer peripheral edge that does not float up and that is stronger than a conventional panel and can maintain a stable structure for a long period of time.

Features.

  Next, the means grasped from the description of claim 7 is to block the exposed surface of the laid panel and the exposed surface of the sheet material, vibration absorbing material or reinforcing material provided as necessary. It is characterized by applying a thermal paint.

Next, how the problem is solved by means grasped from the description of each claim will be described. First, in the means grasped from the description of claim 1, the panel is shaped by laying a quadrilateral panel on the roof of the building, and a flat flange portion having a constant width is formed on the four sides of the panel. By forming the shape, the shape of the panel can be simplified, the flanges of the four panels that are abutted together can be pressed and fixed, and further raised from the flange portion at a predetermined inclination angle to form a ridgeline. By forming a pyramid-shaped convex panel surface, the surface of the roof on which the panel is laid is made an uneven surface to increase resistance, thereby reducing the strength of the wind. The panel has a simple structure in which a heat insulating layer made of foamed resin is provided on the back surface of the skin made of hard resin. In addition, a large number of protrusions are formed on the back surface of the panel, and air containing moisture evaporating from the concrete on the floor surface of the building roof is formed by forming a large number of ventilation layers between the roof surface and the roof surface. And the swelling of the panel due to the water vapor pressure can be prevented.
Furthermore, since the strength of the outer peripheral edge of the flange portion is improved by providing a reinforcing convex portion that is continuous with the outer peripheral edge of the flange portion, by simply driving an anchor bolt and pressing and fixing the reinforcing convex portion with the holding plate, Even after a long period of time, it is possible to prevent the outer peripheral edge of the flange portion from wavy and floating.

  Next, in the means grasped from the description of claim 2, the drainage panel surface and the flange portion are formed by providing a drainage panel surface having a steep inclination angle from the panel surface between the panel surface and the flange portion. The concave portion that functions is functioning as a drainage groove, and it is easy to flow without storing rainwater.

  Next, in the means grasped from the description of claim 3, a sheet material covering the joints between the adjacent flange portions of the laid panel, the holding plate, and the fixing member provided as necessary is provided. By sticking, leakage of rainwater can be prevented by easy work.

  Next, in the means grasped from the description of claim 4, by attaching a reinforcing material covering the entire adjacent flange portion of the laid panel over the entire rooftop structure of the building, when it rains, between the flanges Water leakage from the joints, the gap between the pressing member and the fixing member is prevented. Although the structure in which the sheet material is simply attached on the flange portion or the like in claim 3 can prevent water leakage to some extent, prevention of water leakage by attaching the reinforcing material is much more effective.

  Next, in the means grasped from the description of claim 5, a reinforcing material covering the entire adjacent flange portion of the laid panel is stuck over the entire roof structure of the building, and the vibration absorbing material is placed on the reinforcing material. By sticking over the entire area, it is possible to effectively prevent leakage of water between the flanges and the gap between the holding members when it rains, and even if a large earthquake occurs, the vibration absorbing material Absorbing shaking can effectively prevent panel destruction. Moreover, since the vibration absorbing material is stabilized by sticking the vibration absorbing material on the reinforcing material, the durability of the vibration absorbing material is improved.

The corner of the flange portion of the panel can be fixed. If it does in this way, before fixing this fixing member to a rooftop floor surface, the position of a panel can be determined and the number of anchor bolts can be reduced.

  In addition, as a means by the reference invention 2, a fixing member can be comprised with two members. The reason for the two members is that the fixing member is easy to process and suitable for mass production, and when the fixing member is disassembled, it becomes two rod-shaped members, and the storage location of the warehouse and the site This is to reduce the transportation space. Moreover, since this member uses U-shaped material and forms an air passage between the rooftop floor surface, the panel by the water vapor pressure is released by letting the air containing moisture evaporates from the concrete on the rooftop floor surface. Can be prevented.

  Next, in the means ascertained from the description of claim 6, the panels are laid out, anchor bolts are driven into the corners of the panels, and the reinforcing projections are pressed down with the anchor bolt heads and presser plates to fix the four panels. Then, if necessary, the anchor bolts are driven into the part where the outer peripheral side faces of the panel are facing each other, and the reinforcing projections are pressed down with the anchor bolt head and the holding plate to fix the two panels. It is excellent in strength, can prevent the outer peripheral edge of the flange portion from undulating, and can easily build a stable building roof structure.

  Next, in the means ascertained from the description of claim 7, the exposed surface of the laid panel and the exposed surface of the sheet material, vibration absorbing material or reinforcing material provided as necessary are shielded. By applying the thermal paint over the entire roof structure of the building, the thermal barrier paint absorbs ultraviolet rays, so that the durability of the building roof structure can be improved.

By forming a flat flange portion and simplifying the shape of the panel, mass production is possible and an inexpensive panel can be obtained. Furthermore, a pyramid-shaped convex panel surface that is raised from the flange portion at a predetermined inclination angle to form a ridgeline is formed, and the roof surface on which the panel is laid can be made uneven to reduce the strength of the wind. Therefore, it is possible to prevent the corner panel from being peeled off by the wind, and to prevent peeling of the panel on the entire rooftop. Since the panel has a simple structure in which a heat insulating layer made of foamed resin is provided on the back surface of the skin made of hard resin, the panel can be made inexpensive. In addition, a large number of protrusions are formed on the back surface of the panel, and air containing moisture evaporating from the concrete on the floor surface of the building roof is formed by forming a large number of ventilation layers between the roof surface and the roof surface. And the swelling of the panel due to the water vapor pressure can be prevented.
Furthermore, since the strength of the outer peripheral edge of the flange portion is improved by providing the reinforcing convex portion that is continuous with the outer peripheral edge of the flange portion, the outer peripheral edge of the flange portion is hardly deformed. Furthermore, when the anchor bolt is driven in and the reinforcing convex part is pressed and fixed by the presser plate, the force pressed by the presser plate is concentrated on the reinforcing convex part and does not spread over the entire presser plate. It is effectively prevented that the outer peripheral edge is deformed and waved and floats.

Therefore, the construction man-hours are reduced and an inexpensive roof structure can be obtained.

  Next, on the basis of the description of claim 4, according to the present invention ascertained from the detailed description of the invention, since the reinforcing material covering the adjacent flange portions of the laid panel is adhered, it is rained. When it falls, it is possible to effectively prevent water leakage from the joints between the flanges, the gap between the pressing members, and the gap between the fixing members provided as necessary. Even if the sheet material is stuck on the joint between the flange portions of claim 3 and on a press plate provided as necessary, a certain waterproof effect can be obtained, but by sticking a reinforcing material A far greater waterproof effect can be obtained.

  Next, based on the description of claim 5, according to the present invention ascertained from the detailed description of the invention, a reinforcing material covering the entire adjacent flange portion of the laid panel is adhered, and vibration absorption is performed thereon. Since the material is adhered, the reinforcing material effectively prevents water leakage, and even when a large earthquake occurs, the vibration absorbing material absorbs the shaking of the earthquake, so that the panel can be prevented from being broken. Further, since the reinforcing material is embedded and the vibration absorbing material is embedded on the reinforcing material, the vibration absorbing material is stably attached, so that the durability of the vibration absorbing material is improved.

  As reference invention 1, according to the present invention ascertained from the detailed description of the invention, a cross-shaped fixing member is provided, and the cross of the fixing member is laid along the side of the panel. The anchor bolts are driven in, the corners of the four panels are fixed with the anchor bolt flanges, and the panel can be positioned before fixing this fixing member to the rooftop floor surface. Since the redoing work is eliminated and the number of anchor bolts is reduced, the number of parts is reduced, the number of construction steps is reduced, and an inexpensive roof structure can be obtained.

  In FIG. 3, the panel 18 is laid down, anchor bolts are driven into the corners of the panel 18, the reinforcing projections 40 are pressed by the anchor bolt heads 27 a and the holding plates 28, and the four panels are fixed. Anchor bolts are driven into the portions where the side surfaces face each other, and the reinforcing projections 40 are pressed by the anchor bolt heads 27b and the pressing plates 28, and the two panels 18 are fixed.

Next, Reference Invention 1 and Reference Invention 2 using a fixing member will be described.
In FIG. 8, the fixing member 26 is composed of two members 26a and 26b, and the cross-shaped fixing member 26 is formed by fitting the cut portion 26d. As described above, the reason why the two members 26a and 26b are used is that the fixing member 26 is easily processed and suitable for mass production, and in the state in which the fixing member 26 is disassembled, the two rod-shaped members 26a. This is to reduce the storage location of the warehouse and the space for transportation to the site. The members 26 a and 26 b use U-shaped material and form an air passage between the rooftop floor surface 10. Although not shown in the figure, the surface where the pressing plate 28 abuts is depressed by the thickness of the pressing plate 28 so that both surfaces are matched, and the sheet material 30 to be stuck is prevented from being lifted up. Try to improve sex. 26c is a hole for inserting the anchor bolt 27, and is formed so as to be positioned at the center of the cross.

  9, a cross-shaped fixing member 26 is provided. As shown in FIG. 8, the cross of the fixing member 26 is laid along the side of the panel 18, and an anchor is formed at the center of the fixing member 26. Since the corners of the flange portions 19 of the four panels 18 are fixed by the pressing plates 28 that are driven by the bolts 27 and pressed by the driving force of the anchor bolts 27, the fixed panel 18 can be fixed. That is, the panel 18 can be shaped into a panel 18 having a square shape and a flat and simple flange 19. Then, as shown in FIG. 6, there is no fitting portion or sealing material filling 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. Prior to fixing 26 to the rooftop floor with anchor bolts 27, the panel 18 can be positioned. As a result, it is possible to prevent occurrence of poor positioning, eliminate unnecessary work such as re-fixing of the fixing member 26, and reduce the number of anchor bolts 27.

  And as shown in FIG. 5, by sticking the sheet | seat material 30 on the flange part 19, the fixing member 26, and the pressing member 28 of the laid panel 18, a seal | sticker is ensured and construction work is made easy. 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 portion of the panel 18 where the fixing member 26 is not provided. And the sheet | seat material 30 is stuck so that this gap may be plugged in, and since the members 26a and 26b use U-shaped members to allow air to flow, the gap becomes an air passage, By allowing air containing moisture to evaporate from the concrete on the rooftop floor surface 10, the panel 18 can be prevented from swelling due to water vapor pressure.

Next, a construction example of the roof corner 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 from the roof floor 10 to the vertical wall 16 with a constant radius of curvature R. The curvature radius R is theoretically determined and determined by the height H1 of the building, the height H2 of the vertical wall 16, and the strength of the wind. However, when this 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 at the corners, it is not limited to the theoretically determined radius of curvature R, but in short there is an allowable range based on the theoretically calculated radius of curvature R. Any radius of curvature that rectifies the wind flow may be used. As shown in FIG. 3, when the shaped panel 18 is laid on the floor surface 10 of the roof, the area of the floor surface 10 is not constant, so that a half-end portion is generated. That is, in FIG. 7, the dimension L1 when the panels 18 are laid in order on the floor surface 10 is constant according to the dimensions of the shaped panel 18, so the dimension of L2 is due to the variation in the area of the floor surface 10. It will not be constant.

  At that time, the floor surface 10 side of the corner panel 31 is cut and adjusted so as to have a dimension L2. This allows the use of the shaped panel 18. That is, the panel 18 can be shaped. Further, in order to ensure the strength against peeling of the corner panel 31, the anchor bolt 27 may be driven. In this case, the member 26a of the fixing member 26 serves to reinforce the corner panel 31, so that the peeling of the corner panel 31 can be further suppressed. Moreover, a cutting line is put in the heat insulation layer 25 so that the corner panel 31 can be easily bent in the field, and the heat insulation 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 between the floor 10 on the building roof and the vertical wall 16, and this radius of curvature R is the height H1 of the building and the height of the vertical wall 16. Since it is theoretically determined by H2 and the wind speed and the flow of the wind is rectified as indicated by the arrow B or C, the negative pressure generated at the corner is reduced and the bending radius R is increased to increase the peeling 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 FIG. 11 and FIG. 12, the air outlet 33 of the corner panel 31 is tapered by bending the end of the collar 34 and the tip of the corner panel 31 so that the air is normally emitted as indicated by an arrow A. The corner panel 31 is prevented from peeling off by preventing backflow from the air outlet 33 in a typhoon or the like. Further, an anchor bolt 27 is driven on the air outlet 33 side of the corner panel 31 with the U-shaped contact member 32 interposed so that air can flow, so that the corner panel 31 can be prevented from peeling off more reliably. It may be.

Although not shown, a thermal barrier coating is applied to the exposed surface of the laid panel and the exposed surface of the vibration absorbing material or reinforcing material provided as necessary.

  Next, the operation of this embodiment configured as described above will be described. As shown in FIG. 3, a quadrilateral panel 18 is laid on the rooftop floor surface 10 of the building, and reinforcing convex portions 40 are provided continuously on the entire outer peripheral edge of the flange portion 19 to reinforce the corner portions of the flat flange portions 19. The panel 18 can be formed into a simple shape by fixing it with the single pressing plate 28 from above the convex portion 40. Then, as shown in FIG. 1, by forming flat flange portions 19 with a constant width on the four sides of the panel 18, the shape of the panel 18 can be simplified, and reinforcement that is continuous with the outer peripheral edge of the flange portion 19. By providing the convex portion 40 to improve the strength, the panel outer periphery rises and undulates for a long time after the rooftop structure is constructed, and a gap is generated between the anchor bolt presser plate and the stability of the panel. Is prevented from being damaged. Further, since the force is concentrated on the reinforcing convex portion 40 by pressing the reinforcing convex portion 40 with the presser plate 28, the reinforcing convex portion 40 can be further pressed against the flange portion 19 and stable from this point. Improves.

  Further, by forming a pyramid-shaped convex panel surface 20 that is raised from the flange portion 19 at a predetermined inclination angle and formed by the ridge line 23, the surface of the rooftop 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 reduce 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 36 a is provided at the lower portion of the panel surface 20, and is formed as a drainage panel surface 35 having a steep downward slope from the reinforcing flange portion 36. Therefore, the concave portion formed by the drainage panel surface 35 and the flange portion 19 functions as a drainage groove, so that it is easy to flow rainwater without accumulating. Further, since the reinforcing flange portion 36 is provided, the strength of the panel is improved.

  As shown in FIG. 6, the reinforcing material 37 is provided over the entire rooftop structure of the building until it reaches the drainage panel surface 20b from the drainage panel surface 20a 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, water leakage from the joints between the flanges, the gaps between the pressing members, and the fixing members is more reliably prevented.

  As shown in FIG. 7, the reinforcing member 37 is provided over the entire rooftop structure of the building until it reaches the drainage panel surface 20b from the drainage panel surface 20a 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 gap between the fixing member and the pressing member is more reliably prevented, and even when a large earthquake occurs, vibration Since the absorber 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 shaped in a substantially square shape is laid, the panel 18 is raised from the flange portion 19, the top surface of the roof is made uneven, and the resistance of the wind that flows on the roof is increased. Combined with reducing the strength (wind pressure) of the corner panel 31, the corner panel 31 can be prevented from peeling more reliably by increasing the straightening effect of the corner panel 31 and increasing the bending strength in the peeling direction. It is also possible to prevent peeling of the panel 18 as a whole.

  Further, as shown in FIG. 3, by fixing the portions where the reinforcing projections at the corners and sides of the panel are formed using the anchor bolts 27 and the holding plate 28, the roof structure of the building using the panels can be easily achieved. The completed rooftop structure can be stably maintained for a long time.

  Although not shown, since the entire rooftop structure of the building is applied with a thermal barrier paint, deterioration due to ultraviolet rays is suppressed, and the usable life is greatly extended.
