Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in References 1 and 2, a backup agent and a joint material are filled in the gap, and water leakage due to deterioration of the material cannot be avoided. Further, in Reference 3, a drainage member is formed on the back side (upper part of the sash) of the structure of Reference 1, but there is a risk that rainwater flowing on the side surface of the sash may enter the wall base from the side surface side.

[0005] In order to solve such drawbacks, in the rain closing structure of an opening such as a dry wall material and a sash used in a building or structure, a vertical planar fixing surface and the lower end of the fixing surface are folded back to the outdoor side for waterproofingsurface A drainage member is used, which consists of a long, thin plate formed in a roughly L-shape in cross-section, a vertical, planar fixing piece, a side piece with one end of the fixing piece folded back at approximately 90 degrees, a decorative piece with the tip of the side piece protruding roughly parallel to the fixing piece, a waterproof section with an L-shape in cross-section, and a drainage section with a gutter-like cross-section protruding outwards at the lower end. A continuous seal is formed on the upper surface of the opening, and the waterproof surface of the thin plate is placed and fixed via the seal. A notch is formed on the lower surface of the opening, with a gap between it and the tip of the decorative piece. The edge is fixed, a retaining edge is fixed to both sides of the opening with a gap in between, a retaining edge is fixed to the top of the opening with a gap in between, the side piece that will become the bottom is partially cut to form a drainage hole, the waterproof part of the water flow member is fixed to the fixing piece at the lower end of the retaining edge formed on both sides of the opening, dry wall material cut to fit the opening is installed via the retaining edge of the opening, a seal is formed in the gap between the opening and the retaining edge, and a gap is formed on the top of the opening without a seal, providing a dry wall material and a rainproofing structure for the opening. [Effects of the Invention]

[0006] The present invention provides a dry wall material and a waterproofing structure for openings (hereinafter simply referred to as waterproofing). stomach According to the structure, (1) by forming drainage holes in the edge of the upper surface of the opening and creating a gap in the upper surface of the opening, rainwater flowing from the surface of the dry wall material can be quickly drained to the outside. (2) By forming multiple notches in the edge of the lower part of the opening, even if the external pressure increases due to wind and rain, the internal pressure inside the edge also increases, making it difficult for rainwater to penetrate inside. (3) By forming a water-flow member, any rainwater that does penetrate inside can be quickly drained to the outside. These are some of the features and effects. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

Examples

[0008] Hereinafter, typical embodiments of the rain storage structure according to the present invention will be described in detail with reference to the drawings. FIGS. 1 to 5, FIGS. 10, FIGS. 11, FIGS. 12, and FIGS. The structure consists of an opening K such as a wall base α and a sash. Although not shown, a waterproof sheet is provided on the wall base α to achieve waterproofing.

[0009] First, as shown in FIG. 1, a sealing S is continuously constructed on the upper part of the upper surface K2 of the opening K. Then, as shown by the arrow a, the disposable board T is constructed as shown in FIG. 2. The disposable board T consists of a fixing surface 1 and a waterproof surface 2. The sealing material S is a caulking material made of silicone-based, modified silicone-based, polyurethane-based, etc., or made of ethylene propylene rubber (EPDM), etc.

[0010] Disposable board T When the construction of the disposable board is completed, a stop edge X consisting of a fixing piece 3, a side piece 4, a decorative piece 5, and a space 6 formed by the fixing piece 3, the side piece 4, and the decorative piece 5 is constructed on the side surface K1, the upper surface K2 , the lower surface K3 of the opening K. At that time, as shown in FIG. 2, a notch is made in the decorative piece 5 part of the stop edge X, and an insertion piece X1 obtained by folding the side piece 4 at 90 degrees is formed, and the insertion piece X1 is inserted into the space 6 of the stop edge X, and the stop edge X is fixed around the opening K as shown in FIGS. 3 and 4. Of course, fixing tools β such as nails and screw bits are used for fixing.

[0011] The trim X installed on the lower surface K2 has notches X2 formed by cutting out portions of the decorative piece 5 at regular intervals, as shown in the enlarged section b in Figure 2. These notches X2 make the internal pressure in the space 6 of the trim X formed on the lower surface K3 after installation equal to the external pressure, preventing rainwater from entering the interior. In addition, the trim X installed on the upper surface K2 has drainage holes 4a formed by cutting out portions of the side piece 4 at regular intervals, as shown in Figure 2.

[0012] The installation of the edge stop X involves first creating a 10 mm gap B at the bottom of the lower surface K3 and fixing the edge stop X in place. Then, a 10 mm gap B is created on the side of the side surface K2 and the edge stop X is fixed in place. Finally, as shown in Figure 5, a 10 mm gap B is created on the top surface K1 and the edge stop X is fixed in place. In addition, as shown in Figure 4, a sealant S is formed before the installation of the edge stop X to prevent rainwater from running sideways between the sacrificial plate T and the back surface of the edge stop X.

[0013] The water-flowing member C is a member formed by bending a thin sheet of metal plate material, as shown in Figures 6(a), (b) to 10(a), (b), and has a trough-shaped water outlet 22 at the bottom to drain rainwater that has seeped inside to the outside.

[0014] As shown in Figure 11, the water flow member C is located at the lower ends of both ends of the opening K. Tonge X It is installed on top of the dry wall material A and is designed to allow rainwater that has seeped inside to flow down to the surface side.

[0015] The cut-out plan view of the water flow component C is as shown in Figures 6(a) and (b). Figure 6(a) shows the area formed to the right of opening K, and Figure 6(b) shows the area formed to the left of opening K. The dotted lines are cutting lines, the dotted lines are lines that are folded back at a 90-degree angle and rise up, and the dashed lines are lines that are folded back at a 180-degree angle.

[0016] The water flow member C is formed from a fixing part 14, a fixing hole 14a, a tongue piece 15, a tongue piece 16, a rising piece 17, a side surface 18, a side surface 19, a side surface 20, a bottom surface 21, and a water flow opening 22.

[0017] Next, the processing method for the water flow component C will be explained. As shown in Figures 7(a) and (b), the tongue pieces 15 and 16 are bent at a 180-degree angle.

[0018] next ,figure As shown in 8(a), the rising piece 17 is 90 degree Fold it. Then, as shown in Figure 8(b), fold sides 18, 19, and 20 at a 90-degree angle along the dashed line. Note that Figures 8(a) and (b) only show the water flow member C on the right side of the opening K, but the water flow member C on the left side is processed in the same way.

[0019] Furthermore, Figure 9(a) is a cross-sectional view along line aa in Figure 8(a), Figure 9(b) is a cross-sectional view along line bb in Figure 8(a), Figure 9(c) is a cross-sectional view along line cc in Figure 8(a), and Figure 9(d) is a cross-sectional view along line dd in Figure 8(b). Figures 10(a) and (b) are perspective views of the water-flowing member C.

[0020] As shown in Figures 10(a) and (b), the water-flowing member C is formed from an L-shaped waterproof section C1 and a gutter-shaped water-flowing section C2 that protrudes outwards from its lower end. The waterproof section C1 collects rainwater that has entered the interior, and the water-flowing section C2 then drains it to the outside.

[0021] As shown in Figure 11, the water flow member C is fixed to the lower ends of the retaining edges X formed on both sides of the opening K by fasteners β.

[0022] Once the installation of the water-flow component C is complete, a packing P is formed as shown in Figure 11 to improve waterproofing. Furthermore, packing P is formed on the upper end of the fixing portion 14, the upper end of the rising piece 17, and the side surfaces of the tongue pieces 15 and 16. Of course, a sealant S may be formed instead of packing P.

[0023] As shown in Figure 11, once the installation of the water-flow member C, packing P, and sealant S is complete, the long drywall material A shown in Figure 13(a) is installed. 12As shown in Figure 14, the drywall material A is processed and installed around the opening K on all sides via retaining strips X. At that time, as shown in Figure 15, the drywall material A is fixed at four points from the surface of the corners between the retaining strips X using fasteners β. Of course, the fasteners β are embedded with sealant S to ensure waterproofing.

[0024] As an example of drywall material A, as shown in Figure 13(a) for a cross-sectional view of drywall material A and in Figure 13(b) for a cross-sectional view of the installed state, a core material 10 is sandwiched between a metal surface material 8 and a back material 9 made of thin metal plates, and it is a long sandwich panel formed from 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 part 13.

[0025] Furthermore, P is a packing formed to enhance waterproofing, windproofing, airtightness, and heat insulation.

[0026] The drywall materials A are fixed to the wall substrate α by fasteners β, as shown in Figure 13(b), by connecting the recessed parts 11 to the protruding parts 12.

[0027] Dry wall material A is formed from metal siding material, ceramic siding material, ceramic, etc. As an example of metal siding material, the metal surface material 8 is made from a thin metal sheet, such as iron, aluminum, copper, stainless steel, titanium, aluminum-zinc alloy plated steel sheet, galvalume steel sheet (registered trademark), enamel steel sheet, clad steel sheet, laminated steel sheet (PVC steel sheet, etc.), sandwich steel sheet (vibration-damping steel sheet, etc.), polyvinyl chloride resin, polycarbonate resin, etc. (of course, this includes colored sheets painted in various colors) which is embossed roll-molded or press-molded. The backing material 9 may be made from one or more of the following: aluminum vapor-deposited paper, kraft 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., laminated together, or a sheet that has been waterproofed or flame-retardant treated.

[0028] The core material 3 is made of a synthetic resin foam such as polyurethane foam, polyisocyanurate foam, phenolic foam, polyvinyl chloride foam, polyethylene foam, polystyrene foam, or urea foam. It is extruded onto the back side of the metal surface material 1 or back material 2, heated to react, foam, and harden, and then the metal surface material 1 and back material 2 are integrally formed. Furthermore, various flame retardants such as lightweight aggregates (perlite granules, glass beads, gypsum slag, talc, shirasu balloons, aluminum hydroxide, etc.) and fibrous materials (glass wool, rock wool, carbon fiber, graphite, etc.) can be mixed into the core material 3 to improve fire resistance and fire prevention.

[0029] Once the installation of the dry wall material A into the opening K is complete, corner caps H are installed on the corners of the trim X via sealant S, as shown in Figures 15 and 16.

[0030] Once the installation of the drywall material A and the edge corner cap H is complete, sealant S is applied to the gap B between the opening K and the edge X, as shown in Figure 16. At that time, a portion of the gap B between the upper surface K2 and the edge X is left without sealant S, so that rainwater that seeps into the edge X through gap B can be discharged through the gap B via the drainage hole 4a of the edge X formed on the upper surface K2.

[0031] Furthermore, as shown in Figure 17, when installing drywall material A in the vertical joints of the general section, sealant S is applied from the fixing portion 13 of the fitting part of drywall material A to the fixing piece 3 of the trim X to enhance waterproofing.

[0032] Figures 18(a)-(c) and 20(a)-(c) are explanatory diagrams showing the trim board M1 and decorative cap M2 used for general-purpose edges, outer corners, and inner corners. [Explanation of Symbols]
