Description

[Technical Field]

[0001] This invention relates to a small edge fastening structure for exterior wall panels that can seal gaps that occur between the pillars that make up a modular house (container house) and the exterior wall panels, preventing rainwater from entering. [Background technology]

[0002] A modular house consists of exterior wall panels placed between vertical supports, and although there are various shapes, they are basically box-shaped. The modular houses are used for various purposes such as offices, stores, and storage sheds, and are popular throughout the country due to their low cost and short construction period. On the other hand, in recent years, large earthquakes that cause houses to collapse have occurred from time to time, so many people are living in modular houses. For example, in the recent Noto Peninsula earthquake, many houses were destroyed or partially destroyed, forcing people to build modular houses and live in them.

[0003] Figure 4 shows the exterior of a typical modular house, with vertical pillars (E), (E)·· at the four corners, and exterior wall panels (A), (A)·· attached between each pillar (E), (E)··. The exterior wall panel (a) is fitted with a door (b) that serves as an entrance and exit, and has a glass window (c) to let in light. In addition, ceiling panels and a roof are attached to the top of the modular house, and floor panels are provided on the floor. Furthermore, the interior may be equipped with an air conditioning unit, and if necessary, a toilet and a washroom.

[0004] FIG. 5 is a cross-sectional view showing a corner portion of a modular house, and FIG. 6 is a cross-sectional view showing a small edge stop (d) into which an exterior wall panel (a) is fitted. The end stop (D) is a long piece of material with a roughly U-shaped cross section, and is made by bending a metal plate, with both ends folded inward. The end stop (d) is nailed to a vertical beam (f) fixed along the upright pillar (e), and a resin (g) is applied and caulked to seal any gaps that occur between the pillar surface and the end stop. The edge of the exterior wall panel (I), which is the side end portion, fits between the two side pieces (H) and (R) of the edge stopper (D), and the tip that is folded in half is in contact with the surface of the exterior wall panel (I). However, if strong winds and rain hit the exterior wall panels, rainwater can seep in through even the smallest gaps.

[0005] The surface of the exterior wall panel (A) is made uneven to improve the design, and Figure 5(a) shows the case where the tip of the outer piece (H) of the edge stop (D) is hooked onto the convex part, while Figure 5(b) shows the case where the tip of the outer piece (H) of the edge stop (D) is hooked onto the concave part. If the uneven pattern of the exterior wall panel (A) is a checkered pattern formed continuously from left to right and up to down, gaps will occur at the tip of the outer piece (H). Rainwater then seeps in through the gap, and the rainwater that passes through the gap penetrates the inner surface of the end stop (D) and reaches the inside of the modular house.

[0006] There have been various documents relating to modular houses in the past, and JP Patent Publication No. 2009-203724 entitled "Exterior wall panel edge stop and exterior wall structure of modular house" is a patent application filed by the applicant on February 28, 2008, which describes an edge stop that is a long material with an approximately U-shaped cross section that is attached along the pillars of a modular house and into which the exterior wall panels that make up the exterior wall fit to seal the gaps between the pillars. The edge stop has two side pieces and a bottom piece, and the outer surface of the bottom piece is provided with a semicircular convex portion and a protruding piece made of an elastic material such as soft resin or rubber, which deforms and abuts against the pillars of the modular house, allowing it to be interposed between the exterior wall panel and the pillars and connect the two.

[0007] In this way, the side edges of the exterior wall panels are fitted into the edge stops and attached, but if exposed to heavy wind and rain, rainwater can seep in through small gaps. [Patent Document 1] "Small-edge fastening of exterior wall panels and exterior wall structure of modular houses" in JP 2009-203724 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0008] In this way, the exterior wall panels of a modular house are attached by fitting them into the edge stops, but with the conventional structure it is not possible to completely prevent rainwater from entering. The problem that this invention aims to solve is this problem, and to provide a small edge stop that prevents rainwater from entering the modular house even when it is hit by a typhoon storm. [Means for solving the problem]

[0009] The edge stopper of this device is a long piece of material with an approximately U-shaped cross section, with an outer piece and an inner piece on either side of the bottom piece, and a space is formed between the outer piece and the inner piece, into which the edge of the exterior wall panel fits and is fastened. Here, the end stop is attached along the pillars of the modular house and is fixed to the vertical bars attached along the pillars. The vertical bars contact the surface of the pillars and the end stop is attached using fasteners such as nails.

[0010] The edge stop is attached with the bottom piece facing the column and the inner piece facing the vertical beam, and the side end portion that becomes the edge of the exterior wall panel is fitted into the space formed between the inner piece and the outer piece. By the way, in order to prevent rainwater from entering the end wood, a seal is applied to close any gaps that may occur. (1) Seal inside the outer piece In order to close a gap formed between the outer wall panel fitted into the edge stopping space and the outer piece, a seal piece made of soft resin is provided inside the outer piece, and the seal piece can be deformed to come into contact with the surface of the outer wall panel and close the gap.

[0011] (2) Seal inside the inner piece In order to close a gap formed between the outer wall panel fitted into the edge stop space and the inner piece, a seal made of soft resin is provided inside the inner piece, and the seal comes into contact with the surface of the outer wall panel to close the gap. (3) Seal for the bottom edge The edge stop is arranged along the pillar, and the bottom piece abuts or is close to the pillar surface, but a sealing piece made of soft resin is provided on the bottom piece to seal the gap formed between the bottom piece and the pillar.

[0012] The corners of the bottom piece and the outer piece are caulked to create a double seal structure that prevents rainwater from seeping in through the gap between the bottom piece and the pillar from reaching the sealing piece. The seals described in (1), (2), and (3) above are installed along the entire length of the end stop, sealing the gaps formed between the end stop and the pillars, and between the end stop and the exterior wall panels, thereby preventing rainwater from entering the interior of the modular house. [Effects of the Invention]

[0013] The edge stopper of this device is attached along the pillars and vertical bars that make up the modular house, so rainwater will not seep into the modular house even when it is hit by strong winds and rain. In other words, the resin sealing piece provided on the inside of the outer piece of the edge stop comes into contact with the surface of the exterior wall panel fitted into the edge stop, thereby preventing the infiltration of rainwater, and preventing gaps from occurring even if the surface of the exterior wall panel has some unevenness. Even if rainwater were to penetrate through the sealing piece and into the inner piece, it would not pass through the seal because the resin seal attached to the inner piece would block the gap between it and the surface of the exterior wall panel.

[0014] Therefore, rainwater cannot seep inside the end stop and into the modular house. Also, the bottom piece of the end stop is in contact with or close to the surface of the pillar, but a soft resin seal piece is provided on the outer surface of the bottom piece and abuts against the pillar surface, preventing rainwater from seeping in between the pillar surface and the bottom piece of the end stop. The surface of the end stopper bottom piece is caulked to seal the gap with the surface of the pillar, thereby preventing rainwater from seeping in and reaching the sealing piece. [Brief explanation of the drawings]

[0015] [Figure 1] FIG. [Figure 2] FIG. 10 is a cross-sectional view showing a corner portion of the modular house. [Figure 3] These are exterior views of a modular house, (a) is a side view and (b) is a front view. [Figure 4] An exterior view of a typical modular house. [Figure 5] FIG. 10 is a cross-sectional view showing a corner portion of a conventional modular house. [Figure 6] FIG. DETAILED DESCRIPTION OF THE INVENTION

[0016] FIG. 1 shows a cross section of an edge stopper 1 according to the present invention, which is configured as a long piece of material having the cross section. As shown in the figure, the edge stopper 1 has a generally U-shaped cross section and comprises an outer piece 2, an inner piece 3, and a bottom piece 4, and has a space 7 into which the edge of the exterior wall panel fits. A soft resin seal piece 5 is provided on the inside of the tip of the outer piece 2, and a soft resin seal 6 is provided on the inside of the tip of the inner piece 3, with the tip of the seal 6 extending in a curved or bent manner toward the space. Furthermore, a seal piece 8 also extends in a curved manner on the outside of the bottom piece 4.

[0017] In this way, the outer piece 2 of the edge stop 1 is provided with a seal piece 5, but in order to protect the seal piece 5 from peeling off when the exterior wall panel is fitted into the space 7, the tip of the outer piece 2 is bent slightly inward to form a protrusion 10. However, the protrusion length of the protrusion 10 is made shorter than that of the seal piece 5. The tip of the inner piece 3 is also thickened by the thickness of the seal 6 attached to the inner surface, and is provided with a protruding piece 11 that protrudes inward. Therefore, when the outer panel is fitted into the space 7, the seal 6 will not be peeled off, and the tip is curved or bent inward and extends so as to come into contact with the surface of the exterior wall panel fitted into the space 7.

[0018] Furthermore, a small protruding piece 9 also protrudes from the bottom piece 4, protecting the sealing piece 8 provided on the bottom piece 4. In other words, the gap between the surface of the pillar is restricted by the protruding piece 9, and the sealing piece 8 is curved appropriately to abut against the pillar surface without leaving a gap, but also to prevent the sealing piece 8 from being crushed or peeled off. The edge stopper 1 of this invention is made by bending a metal plate into an approximately U-shaped cross section, and the protruding piece 10 on the outer piece 2, the convex piece 11 on the inner piece 3, and the convex piece 9 on the bottom piece 4 can be fixed by welding or the like. Alternatively, these protruding pieces 10, 11 and the convex piece 9 can be folded together with the edge stopper 1 to form the bag.

[0019] Figure 2 shows a cross section of a corner of a modular house, where 12 represents a pillar, 13 a vertical beam, 14 an exterior wall panel, and 15 a nail. The pillars 12 are made of a metal such as aluminum, have a rectangular cross section, and stand upright from the floor. The end stop 1 is arranged along the pillars 12 and vertical beams 13, and the inner piece 3 extending larger than the outer piece 2 is fixed to the vertical beam 13 via nails 15.

[0020] The attached edge stopper 1 is fitted to the side edge of the exterior wall panel 14, and is sealed to prevent rainwater from entering. The seal pieces 5 attached to the outer pieces 2 are slightly curved to abut against the surface 16 of the exterior wall panel 14, preventing rainwater from entering inside the outer piece 2. Even if the surface of the exterior wall panel 14 is uneven and forms a checkered pattern that is continuous from side to side and up and down, the seal pieces 5 made of soft resin can fit into the recesses and seal the gaps. Even if rainwater does seep in, it is blocked by the seal 6 on the inner piece 3, preventing the rainwater from entering the modular house. In other words, a double structure is formed along the inside of the end stop 1 to prevent rainwater from seeping in.

[0021] To prevent rainwater from seeping in from the outside of the end stop 1, a caulking process is performed using resin 17 to seal the gap that occurs between the bottom piece 4 of the end stop 1 and the post 12. Because a small protruding piece 9 extends from the bottom piece 4, the tip of this protruding piece 4 abuts against the post 12, forming an appropriate gap, and resin is applied and caulked to completely seal the gap.

[0022] Furthermore, a seal piece 8 made of soft resin is provided adjacent to a protruding piece 9 on the bottom piece 4, forming a double-seal structure. The embodiment shown in Figure 2 is a cross section showing the corner of a modular house, and the two exterior wall panels 14, 14 are perpendicular to each other with a pillar 12 between them. However, in large modular houses, a pillar 12 may be erected between the exterior wall panels 14, 14 to connect the panels.

[0023] Figure 3 shows the exterior of a modular house, with (a) a side view and (b) a front view. The edge stopper 1 of this device shown in Figure 1 not only seals the gaps between the pillars 12 erected at each corner of the modular house and the exterior wall panels 14 to prevent rainwater from seeping in, but can also be attached to the pillars 12 as well as window frames, door frames, floor trusses, and ceiling trusses to prevent rainwater from seeping in.
