[0004] However, in the structures of References 1 and 2, gaps are filled with backup agents and joint materials, which made it impossible to avoid water leakage due to deterioration of the materials. In addition, in Reference 3, a drainage member is formed on the back side (top of the sash) of the structure of Reference 1, but there was a risk that rainwater that flowed down the side of the sash would seep into the wall base from the side.

[0005] In order to solve such a problem, the present invention provides a rainproofing structure for openings such as drywall materials and sashes used in buildings and structures, which has a vertical flat fixing surface and a lower end of the fixing surface folded back to the outside.waterproof surface The opening is formed with a long, substantially L-shaped cross section, a vertical, flat fixed piece, a side piece formed by folding back one end of the fixed piece at approximately 90 degrees, and a decorative piece whose tip protrudes approximately parallel to the fixed piece. A continuous seal is formed on the top surface of the opening, the waterproof surface of the seal is placed and fixed via the seal, a notch formed by partially cutting out the tip of the decorative piece is fixed to the bottom surface of the opening through a gap, the notch is fixed to both sides of the opening through a gap, and a notch is fixed to the top surface of the opening through a gap, the side piece that forms the bottom surface is partially cut out to form a drainage hole, opening corner packing is formed on the fixed piece at the four corners between the notches, and a drywall material cut to fit the opening is installed via the notches of the opening, a seal is formed in the gap between the opening and the notches, and a notch is fixed to the top surface of the opening through a gap. A gap was left between the top surface and the edge. The present invention provides a drywall material and a weatherproofing structure for an opening, characterized by the above. Effect of the Invention

[0006] The drywall material and the rainproofing structure for the opening according to the present invention (hereinafter simply referred to as rainproofing) stomach According to the structure, (1) drainage holes are formed in the stopper edge at the top of the opening, and gaps are formed on the top of the opening, so rainwater flowing from the surface of the drywall material can be quickly drained to the outside. (2) triangular opening corner packing is glued and fixed to the four corners of the end of the stopper edge formed in the opening, so rainwater is prevented from seeping into the wall base from the corners. (3) multiple notches are formed in the stopper edge at the bottom of the opening, so even if external pressure increases due to wind and rain, the internal pressure within the stopper edge also increases, making it difficult for rainwater to seep inside. (4) Waterproofing from the surface side using caulking material after construction can be eliminated, improving construction ease, improving the external design, and preventing deterioration of the caulking material due to ultraviolet rays. These are some of the features and effects. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS EXAMPLES

[0008] Representative examples of the rainproofing structure according to the present invention will be described in detail below with reference to the drawings. Figs. 1 to 8 are explanatory diagrams for explaining the construction sequence of the rainproofing structure according to the present invention. As shown in Fig. 1, the structure is composed of a wall base α and an opening K such as a sash. Although not shown, a waterproof sheet is installed on the wall base α to improve waterproofing. The wall base α is an existing wall base or a newly built wall base.

[0009] First, a sealant S is applied continuously to the top of the upper surface K2 of the opening K. Then, as indicated by the arrow a, a backsplash T is applied as shown in Fig. 2. The backsplash T consists of a fixed surface 1 and a waterproof surface 2. The sealant S is a caulking material made of silicone, modified silicone, polyurethane, etc., or ethylene propylene rubber (EPDM), etc.

[0010] When the installation of the backing board T is completed, the fixed piece 3, the side piece 4, and the decorative piece as shown in Figure 2 are installed. 5 The stop edge X, which is made up of the space 6 formed by the fixed piece 3, the side piece 4, and the decorative piece 5, is formed on the side surface K1 and the top surface of the opening K. K2 , bottom surface K3 At that time, as shown in Fig. 2, the decorative piece 5 is cut out from the edge X, and the side piece 4 is folded back at 90 degrees to form an insert piece X1, which is inserted into the space 6 of the edge X to fix the edge X around the opening K as shown in Figs. 3 and 4. Of course, a fixture β is used for fixing.

[0011] Bottom surface K3 The edge X to be installed on the lower surface K2 has cutouts X2 formed by cutting out the decorative piece 5 at regular intervals as shown in the enlarged portion b of Fig. 2. These cutouts X2 make the internal pressure in the space 6 of the edge X formed on the lower surface K3 after installation equal to the external pressure, preventing rainwater from penetrating inside. Also, the edge X to be installed on the upper surface K2 has drainage holes 4a cut out at regular intervals in the side piece 4 as shown in Fig. 2.

[0012] The construction of the edge X is carried out by first fixing the edge X to the lower part of the lower surface K3 with a gap B of 10 mm. K1 Fix the edge X with a 10mm gap B on the side of the K2 The upper surface of the stopper is fixed with a 10 mm gap B. Edge X A sealing S is formed before the construction of the above to prevent rainwater from running sideways between the back surface of the back plate T and the stop edge X.

[0013] Once the installation of the stop edges X is complete, triangular opening corner packings P are glued and fixed to the four corners of the ends of each stop edge X, as shown in Figure 5. The opening corner packings P are installed to prevent rainwater from entering through the corners.

[0014] After the installation of the opening corner packing P is completed, the long drywall material A shown in Figure 6(a) is processed as shown in Figures 5 and 7 and installed at the top, bottom, left and right of the opening K via the stopper edges X. At that time, the surface of the drywall material A at the corner between the stopper edges X is fixed at four points with the fixing device β. Of course, the fixing device β is a sealant. GuS It is buried in order to make it waterproof.

[0015] One example of drywall material A is a long sandwich panel formed by sandwiching a core material 10 between a metal surface material 8 and a back surface material 9 made of a thin metal plate, and comprising a recess 11 formed at the lower end in the width direction, a protrusion 12 formed at the upper end, an upper end recess 12a formed by folding the back surface of the protrusion 12 upward, and a fixing portion 13, as shown in Figure 6(a) which is a cross-sectional view of drywall material A and in Figure 6(b) which is a cross-sectional view of the installed state.

[0016] P1 is a gasket formed to enhance waterproofing, windproofing, airtightness, and thermal insulation.

[0017] Drywall A The recessed portions 11 are connected to the protruding portions 12, and the wall base α is fixed to the wall base α by the fasteners β as shown in FIG. 6(b).

[0018] The drywall material A is formed from a metal siding material, a ceramic siding material, ceramics, etc., and as an example of the metal siding material, the metal surface material 8 is formed by embossing roll molding or press molding a thin metal plate, such as iron, aluminum, copper, stainless steel, titanium, aluminum-zinc alloy plated steel plate, galvalume steel plate (registered trademark), enamel steel plate, clad steel plate, laminated steel plate (vinyl chloride steel plate, etc.), sandwich steel plate (vibration-damping steel plate, etc.), polyvinyl chloride resin, polycarbonate resin, etc. (including color plates painted with various colors, of course). The back surface material 9 may be a laminate of one or more of aluminum-deposited paper, craft paper, asphalt felt, metal foil (Al, Fe, Pb, Cu), synthetic resin sheet, rubber sheet, cloth sheet, gypsum paper, aluminum hydroxide paper, glass fiber nonwoven fabric, etc., or a sheet-like material that has been waterproofed or flame-retardant treated.

[0019] The core material 3 is made of a synthetic resin foam such as polyurethane foam, polyisocyanurate foam, phenol foam, polyvinyl chloride foam, polyethylene foam, polystyrene foam, urea foam, etc., and is dispensed onto the metal surface material 1 or the back side of the back material 2, and is heated to react, foam, and harden to form the metal surface material 1 and the back material 2 together. In addition, lightweight aggregates (perlite particles, glass beads, gypsum slag, talc stone, shirasu balloons, aluminum hydroxide, etc.) and fibrous materials (glass wool, rock wool, carbon fiber, graphite, etc.) can be mixed into the core material 3 as various flame retardants to improve fire resistance and fire prevention.

[0020] After completing the installation of the drywall material A in the opening K, install the edge corner cap H in the corner portion of the edge X as shown in FIG.

[0021] After the installation of the drywall material A is completed, the packing P1 and the sealant S are installed in the gap B between the opening X and the stop edge X as shown in Figures 8 to 11. In this case, the packing P1 and the sealant S are not installed in the gap B between the upper surface K2 and the stop edge X, but are formed so that rainwater that has entered the stop edge X through the gap B can be discharged from the gap B.

[0022] Furthermore, when constructing the drywall material A as shown in Fig. 5, a sealant S is applied between the fixing portion 13 of the fitting portion of the drywall material A and the fixing piece 3 of the stopper edge X to enhance waterproofing. Of course, as shown in Fig. 12, a sealant S is applied to the joint portion M consisting of the general portion's batten M1 and decorative cap M2.

[0023] 9 to 11 show the rainproofing of the present invention. stomach 1 is an explanatory diagram and a cross-sectional view showing the mechanism of the structure.

[0024] In FIG. 9, the upper surface K2 of the opening K is provided with a rainproofing. stomach This shows the structure, and even if rainwater W penetrates through the edge X or the edge corner cap H, the opening corner packing P and the backing board T formed on the left and right sides prevent the rainwater from penetrating into the wall base α, and the rainwater is prevented from penetrating into the wall base α formed on the edge X. Drain hole 4a Water is drained to the outside through gap B.

[0025] In FIG. 10, the rainproofing of the left and right side K1 portions of the opening K is stomach This shows the structure, and even if rainwater W seeps in through the fixed piece 3 of the stop edge X or the stop edge corner cap H, the opening corner packing P and sealing S formed on the left and right sides prevent the rainwater from seeping into the inside of the wall base α, and the rainwater is discharged to the surface side of the drywall material A.

[0026] FIG. 11(a) and (b) show the lower part K3 of the opening K. RainproofThe diagrams show the structure, and Fig. (a) shows the case where no notch X2 is formed in the edge X, and when the external pressure increases due to wind and rain, the internal pressure in the edge X decreases, and the difference in pressure makes it easier for rainwater to seep inside. In contrast, Fig. (b) shows the case where multiple notches X2 are formed in the edge X, and even if the external pressure increases due to wind and rain, the internal pressure in the edge X also increases, making it difficult for rainwater to seep inside.
