Description

ROOF STRUCTURE OF BUILDING}

The present invention relates to a structure of a roof of a building, and more particularly, it is usually very windy, and a panel for insulation and waterproofing of a rooftop of a building, in particular, a roof of a high-rise building, which generates stronger winds during a typhoon, is easily It relates to a roof structure of a building that does not fall or blow in the wind, the panel itself is inexpensive, and construction is simpler.

In general, the roof of the building is used as a waterproof and thermal insulation panel. However, a strong wind blows on the roof of a building, especially a high-rise building, and when a typhoon blows, a stronger wind blows the panel or blows it away, reducing the waterproofing and insulation of the building. It can also damage adjacent buildings or people. Therefore, such a panel should be fixed more strongly on the roof of the building, the panel itself should be cheaper, and the construction should be simpler.

As shown in FIG. 10, an example of a conventional building roof structure (published in Japanese Patent Laid-Open No. 3-87467) shows that the panel 1 has a heat insulating material 4 between the surface material 2 and the back surface material 3. I install it. And the joint 9 part of each panel 1 has the complicated shape which abuts together like a tongue. In addition, the fixing hardware 5 for installing the joint protective cover 6 is fixed with screws 7, respectively, and the panel 9 is covered with the joint 1 while filling the caulking material for sealing purposes. Next, the anchor bolt (8) is fixed to the bottom surface of the building roof, and the joint protection cover (6) to be fitted into the fixing hardware (5) there is a problem that the construction is quite difficult.

As shown in FIG. 11, another example of a conventional roof structure of a building (published in Japanese Patent Laid-Open No. 9-279713) shows that a board 11 can be placed over the surface material 2 of the panel 1. In addition, the concave surface is formed so that the head of the anchor bolt (8) can enter. Moreover, the core material 13 for maintaining the fixing force of the anchor bolt 8 is hidden in the heat insulating material 4 in this rear surface part. First, the joint plate 14 is fixed to the rooftop surface 10 with an anchor bolt 15, and then the panel 1 is fitted to the joint plate 14, and the joint 9 is attached. Fill the sealing material and fix the panel 1 to the rooftop bottom surface 10 with the anchor bolt (8). Next, the board 11 attached with the fixing hardware 5 for installing the joint protective cover 6 at both ends is placed over both ends of the panel 1, and the anchor bolts 12 are used for the rooftop surface. It is pointed out that the construction is quite difficult, such as to secure the joint cover 6 to the fixed hardware 5 after fixing to (10).

As shown in FIG. 12, in the conventional example of the rooftop edge portion, the edge panel 17 installed between the rooftop bottom surface 10 and the vertical wall 16 has a vertical wall (from the rooftop floor surface 10). According to 16), it has a small radius of curvature and is bent to almost 90 degrees, and the air escapes as indicated by arrow A.

The conventional examples described above are complicated in the shape of the joint part of the panel, and in particular, the conventional example as shown in FIG. 10 has a jagged shape such that the joint part meets a male and a male. There is a problem that the mold for molding the mold is complicated, and two types of molds are required and the panel price becomes considerably high. In addition, when a panel having such a complicated shape is used as a standard four-sided panel and laid on the floor of the rooftop, the joint portion of four panel edges joined together becomes complicated and it is almost impossible to form a four-sided panel. can do. In addition, since the panel itself is enlarged, it is difficult to mass produce, and the price is relatively high.

In actual construction, there are many kinds of parts such as joint protection cover, fixing hardware for installing such cover, many anchor bolts, filling of sealing material, etc., and the number of construction process is extremely increased, and the price is too expensive for the roof structure of the building. there is a problem. In addition, in the conventional example as shown in FIG. 11, the joint plate 14 must be fixed in advance by the anchor bolt 15. Therefore, if the position of the joint plate 14 is a little inaccurate, break the concrete of the rooftop surface 10, remove the anchor bolt 15, refill the broken concrete part, and anchor the anchor at the new correct position. There is also a significant problem in constructability, such as the need to install the bolt 15.

Next, in the conventional example shown in Fig. 12, when the wind blows in the directions of arrows B and C, vortices such as those shown by the arrows are generated in the corner portions, and thus negative pressure is generated in the corner portions D. As a result, the force F acts on the edge panel 17 in the direction taken out from the vertical wall 16. In addition, since the edge panel 17 is bent to a nearly right angle with a small radius of curvature, the edge panel 17 provided along the vertical wall 16 is likely to be bent in the direction of the force F, and may fall off at this portion. The problem is likely to be pointed out. In particular, even if a part of the edge panel 17 falls off, the entire edge panel 17 is pulled out, which leads to a more serious problem in which the panel 1 of the rooftop floor 10 is also pulled out.

Therefore, the present invention was created in view of the above-described conventional problems, and the object thereof is to simplify the shape of the panel, and even to form a panel, the construction is easy and mass production is possible, thereby making the panel at a low price. In addition, the construction process is simplified to shorten the construction period, and to provide a roof structure of the building that can prevent falling off the corners.

<Example>

Next, an embodiment of the present invention will be described.

1 is a schematic square in front view of panel 18. And the flat flange part 19 is formed in four sides. Moreover, the step part 22 is provided in the corner part, When this step part 22 presses the corner of the panel 18 with the press board 28, as shown in FIG. 6, the upper surface of the press board 28 and a plan The upper side of the branch 19 was made to match. In this way, the adhesion of the adhesive layer 30 becomes a flat surface as shown in FIG. 4, so that the adhesion layer 30 does not float, and the adhesion is improved to prevent the dropping over time. In addition, when the adhesive layer 30 is used as a sheet | seat as shown in FIG. 4, the step part 21 becomes the level | step difference of the height substantially the same as the thickness of a sheet | seat, and the step part 21 in the state which covered the panel 18 was filled. The distance W1 between them is almost equal to the width of the sheet of the adhesive layer 30, so that rain water does not collect easily. Moreover, the panel 18 protrudes from the step part 21 of the flange part 19 to the gentle inclined surface 18a as shown in FIG. 4, and as shown in FIG. 1, the angular abstract which has the ridge 23 is shown. It is in the form of 凸. In addition, the surface of the panel surface 20 is 凹凸, and such a shape increases the 전체 of the entire roof covering the panel 18 to increase the resistance to wind passing through the rooftop surface, thereby increasing the resistance to the edge panel 31. It reduces negative pressure and prevents people from slipping when walking.

FIG. 2 shows the back of FIG. 1, and as shown in FIG. 4, the projections 25a are formed on the inner surface of the panel 18, and a plurality of ventilation layers are formed between the rooftops and the bottom surface 10. 25b) can prevent air swelling of the panel 18 due to water vapor pressure by discharging air containing moisture evaporating from the concrete of the floor surface 10 on the roof of the building. In addition, large projections 25c were provided (nine in the present embodiment) so as to have sufficient strength to cope with the load applied from the upper surface of the panel 18.

The fixing member 26 in FIG. 5 consists of two members 26a and 26b, and when the cut-out part 26d is inserted, it becomes a cross-shaped fixing member 26. As shown in FIG. The reason for the two members 26a and 26b as described above is that the fixing member 26 can be easily processed to allow mass production, and in the state where the fixing member 26 is disassembled, two members 26a and 26b in the shape of rods are formed. In order to reduce the storage space of the warehouse and the transport space on site. In addition, the two members 26a and 26b form an air passage between the rooftop bottom surface 10 using a U-shaped material. Although not shown in the drawing, the step where the pressing plate 28 of the anchor bolt 27 is in contact with each other is provided with a step by the thickness of the pressing plate 28 so that the flat surface is not raised and the adhesive layer 30 is lifted up so that the adhesion is good. Doing. The holes 26c drilled into the two members are located at the center of the cross as holes for penetrating the anchor bolts 27.

In FIG. 7, the corner panel 31 is installed with a constant radius of curvature R from the rooftop floor 10 to the vertical wall 16, and the radius of curvature R is the height H1 of the building. It is theoretically determined according to the height H2 of the straight wall 16 and the wind strength. In this way, when the radius of curvature R is theoretically determined, the radius of curvature R is determined uniformly, but the basis of the determination is to adjust the wind in the direction C as indicated by the arrow B or the dotted line, as indicated by the solid arrow. Since it is to reduce the negative pressure generated at the corners, the curvature can adjust the flow of wind within the allowable range based on the theoretical radius of curvature (R), not limited to the theoretical radius of curvature (R). The radius R may be sufficient. When the panel 18 shape | formed as shown in FIG. 3 was filled and laid on the roof bottom surface 10, the area of the bottom surface 10 is not constant, and a dent part is produced. That is, as shown in FIG. 7, the dimension L1 when the panel 18 is sequentially filled and laid on the bottom surface 10 is determined according to the dimensions of the panel 18 that has been shaped, but the area of the bottom surface 10 is determined. Depending on the difference, the dimensions of L2 are not constant. At this time, if the bottom surface 10 of the edge panel 31 is cut and adjusted to have the dimension L2, the shaped panel 18 can be used. In addition, in order to secure the strength against dropping of the edge panel 31, the anchor bolt 27 'may be poured. In this case, the member 26a of the fixing member 26 serves as a reinforcing role of the edge panel 31, so that the dropout of the edge panel 31 can be more strongly fixed. In addition, the heat insulation layer 25 is cut so that the bending of the edge panel 31 at the site is easy, so that the heat insulation layer 25 is separated from the cutting line.

In FIG. 8 and FIG. 9, the end portion of the edge portion 34 and the end portion of the edge panel 31 are folded and tapered to cover the air outlet 33 of the edge panel 31. When the air is discharged and strong winds such as typhoons are blown, it is prevented from falling back to the air outlet 33 to prevent the edge panel 31 from falling off. In addition, the fastening member 27 'is placed on the air outlet 33 side of the edge panel 31 via the U-shaped support member 32 to allow the flow of air. You may prevent it.

Referring to the operation of the present embodiment configured as described above, first, as shown in Fig. 3, the quadrilateral panel 18 is filled with the roof top surface 10 of the building, and the corners of the flange portions 19 which are flat with each other. By fixing the part by one press plate 28, the panel 18 can be made into the simple shape shape standardized. And as shown in FIG. 1, the shape of the panel 18 is simplified by forming the flange part 19 flat on the four sides of the panel 18 by the fixed width, and from the flange part 19, As the protruding panel surface 20 is formed at a predetermined inclination angle, the entire roof surface covered with the panel 18 becomes the convex surface to increase the resistance to wind passing through the roof surface, thereby reducing the intensity of the wind. At the same time, it can prevent people from slipping when walking. In addition, the panel 18 may have a simple structure having a heat insulation layer 25 made of a foamed resin inside the skin 24 made of a hard resin.

In addition, as shown in FIG. 5, a cross-shaped fixing member 26 is provided, and as shown in FIG. 6, four sides of the panel 18 are aligned with the cross of the fixing member 26, and then the fixing member ( The fastening member 27 is placed at the center of the 26 to fix the corners of the flange portion 19 of the four panels 18 by the pressing plate 28 pressed by the fastening force of the fastening member 27. Therefore, the standardized panel 18 can be fixed. That is, the panel 18 can be shaped into a panel 18 having a quadrangular shape and having a flat and simple flange 19. As shown in FIG. 6, the fixing member 26 is only provided because the two sides only need to be faced together without interposed between the side surface of the panel 18 and the side surface of the fixing member 26 or filling the sealing material. It is possible to determine the position of the panel 18 before fixing the fastening member 27 to the rooftop surface 10. By doing so, it is possible to prevent defects due to positioning, and to eliminate the need for extra work such as refreshing the position of the fixing member 26, and the number of fastening members 27 can be reduced.

As shown in FIG. 6, the sealing layer is secured by placing the adhesive layer 30 on the flange portion 19, the fixing member 26, and the pressing plate 28 of the panel 18 filled with the adhesive layer. The construction work can be done easily. Moreover, since each member 26a, 26b of the fixing member 26 is short, the clearance part corresponding to the width | variety of the members 26a, 26b arises in the joint part of the panel 26 of each other which does not have this fixing member 26. . Therefore, the adhesive layer 30 is adhered to prevent the gap, and the members 26a and 26b allow the air to flow using the U-shaped member, so that the gap becomes an air passage and the rooftop Since the air containing the water evaporated from the concrete of the surface 10 is discharged to prevent the swelling of the panel 18 by the water vapor pressure.

As shown in FIG. 7, a corner panel 31 having a predetermined curvature radius R is installed over the floor surface 10 and the vertical wall 16 of the roof of the building, and the curvature radius R is the height of the building. (H1), the height (H2) of the vertical wall 16 and the wind strength is determined theoretically. Therefore, by adjusting the flow of wind in the direction of arrow B or C, the negative pressure generated at the corners can be reduced, and the dropping of the edge panel 31 can be suppressed. In addition, as shown in Fig. 3, the panel 18 formed into a substantially square shape is filled, and the panel 18 is protruded from the flange portion 19 to swell the upper surface of the rooftop to increase the resistance of the wind flowing through the rooftop. In addition to weakening the wind strength (wind pressure) and increasing the flexural strength of the edge panel 31 in the adjustment direction of the wind and the dropping direction, the dropping of the edge panel 31 is more reliably prevented, and further, the panel 18 The fall of the whole can also be prevented.

As described above, the present invention is to form a quadrilateral panel to fill the roof of the building according to the description of the claim 1 and the detailed description thereof, and to form a flat flange of a certain width on the four sides of the panel By simplifying the shape of the panel, mass production is possible, thereby making the panel inexpensive. In addition, a flat panel surface formed by projecting a predetermined inclination angle from the flange portion can be formed, and the wind strength can be reduced by using the roof surface covered with the panel as a flat surface to prevent the panel from falling off due to wind. It is possible to prevent the rooftop panel from falling off. And, since the panel has a simple structure having a heat insulation layer made of foamed resin inside the skin made of hard resin, the panel can be made inexpensive.

Next, the present invention is to make and install a cross-shaped fixing member, and to lay each side of the panel to the cross of the fixing member, install a fastening member in the center of the fixing member by the pressing plate of the fastening member corner of the four panels The part can be fixed and the panel can be positioned before the fixing member is fixed on the roof floor, so rework due to poor positioning can be avoided, the number of fastening members can be reduced, and the construction period can be shortened.
