Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vertical joint structure when forming a flat outer wall of a building using panels. Particularly when installing panels horizontally to form a wall, it is easy to construct the panels, and in addition, the vertical joints, the nail heads that fix the panel ends that are the left and right ends of the vertical joints, and the fittings that install the joint covers. This invention relates to a vertical joint structure of a wall using a panel that has a beautiful appearance in which the vertical joints and their fixing devices do not appear at all in the appearance of the vertical joints, and has significantly improved waterproofness of the vertical joints. There are two types of walls constructed using panels: vertical and horizontal.In horizontal walls, the joints are horizontal, approximately the width of the panel, so-called horizontal joints, and the vertical joints formed by the longitudinal end faces of the panels. Joints, so-called vertical joints, appear on the exterior. There are various waterproofing and design treatments for vertical joints that have been conventionally carried out, but for example, a vertical joint structure in which the vertical joint space is simply filled with a caulking agent is commonly used.
However, in order to fill the vertical joints with caulking agent and obtain sufficient waterproofness and design, it is necessary to form the joints to a width of at least 5 mm to 10 mm, and then paint the entire exterior wall, which increases costs. Another drawback was that the construction period was also long.
In addition, the above method has the disadvantage that the caulking agent is exposed to the outside air and must be repaired every few years due to weather resistance. Furthermore, if the vertical joints are treated with caulking, it is essential to drive a nail into the edge of the panel near the vertical joint to secure the panel, so that the nail head matches the color of the exterior wall. It is very difficult to match the colors as described above. As a countermeasure, there is a method of treating the entire exterior wall with a decorative coating, but this method has the disadvantage of being expensive. Additionally, when caulking the vertical joints, precision is required to line up the ends of the panel ends in a straight line from the base to the eaves and apply caulk to the joints of the same width, which has the disadvantage of significantly reducing work efficiency. Ta. Additionally, it is common to use an H-shaped jointer or a hat-shaped jointer to cover vertical joints, but this requires a large gap between the panel edge and the H-shaped jointer. It is extremely difficult to fill with caulking material, and it is not easy to fix the panel ends with nails. In addition, in the latter case, the nails would be hit in the head, so the structure was not desirable in terms of appearance and waterproofing. In order to eliminate such drawbacks, the present invention reduces the width of the vertical joint, and fixes it to the frame by, for example, nailing the end of the panel that will be the end of the vertical joint with the end surfaces of the panels abutted against each other. Next, fill the gaps between the vertical joints, the so-called panel edges, with joint material, and then place multiple fixtures on the vertical joints and fix them to the frame with nails. The joint cover engages with the fixture through elastic deformation, covering all of the nail heads exposed at the vertical joint, the panel edges of the joint, and the fixture, creating a beautiful appearance and waterproofing. This project proposes a vertical joint structure with excellent workability. The vertical joint structure of a wall using the panel according to the present invention (hereinafter simply referred to as joint structure) is shown below using the drawings.
An example will be described in detail. FIG. 1 is a perspective view showing a part of a wall having the joint structure described above, in which 1 is a panel, 4 is a fixture, 8 is a joint cover,
12 is a vertical joint, 12a is a vertical joint part, 13 is a joint material made of, for example, waterproofing agent or caulking material, 14 is a fixing device, which is a nail in the figure, and 15
is a frame body consisting of main pillars 16 and studs 17. To explain further, the panel 1 is a long body consisting of a single or composite sandwich structure having a male connecting part 2 and a female connecting part 3, as shown in FIGS. 2a to 2f. In fact, the wall surface is at least substantially flush. In addition, the fixture 4 is formed by molding one type of metal plate, synthetic resin plate, etc., and has a substantially gutter-like cross section consisting of a bottom surface portion 5 and two leg portions 6, as shown in FIGS. 3a to 3i, for example. The main purpose is to easily lock the joint cover 8 without detaching it. In addition, a plurality of fixtures 4 are installed on the vertical joint part 12a at a predetermined pitch and are arranged so as to cross the vertical joint part 12a, and in addition, the bottom part 5 is separated from the surface of the panel 1 , The tips of the legs 6 are placed in contact with the surface of the panel 1 , and the center of the bottom 5 is fixed to the frame 15 with a nail 14. Furthermore, to explain the fixture 4 , figure a shows a fixture in which the bottom part 5 is flat, and both ends thereof are inclined at an angle θ ₁ (acute angle) to form legs 6, and figure b shows the legs 6. A fixture formed in a dogleg shape; Figure c is a fixture in which the tip of the leg 6 shown in Figure B is extended and horizontally bent inward to form a stabilizing piece 6a; Figure d is a fixture formed with the leg 6. ′ in a dogleg shape,
The other leg part 6 is set at θ ₂ =90°, and Figure e shows the fixture shown in Figure B, with a nail head buried in the center of the bottom part 5 and a rib 5a serving as a reinforcing structure. In the figure f, the rib 5a is formed widely,
Figure g shows a fixture with a mounting hole 5b formed in the center, Figure h shows a fixture with a circular rib 5a' in which a nail head is embedded in the center of the bottom part 5, i The figure shows a fixture in which the tips of the legs of the fixture shown in Figure b are extended vertically to the bottom surface 5. In addition, the leg part 6
The width W ₁ between the tips is larger than the width ΔW of the vertical joint portion 12a, for example, about 10 to 100 mm, and the height h ₁ is 2 to 100 mm.
Approximately 20mm, length L ₁ is 5 to 100mm, width W ₂ of bottom part 5 is
It is about 13-120mm. The joint cover 8 is made of one kind of metal or synthetic resin formed to a thickness that can exhibit elastic deformation, for example, as shown in FIGS. Joints 12 , nail heads driven into the panel ends, decorative material that covers the fixture 4 to prevent the heads of fixing tools from being exposed at the vertical joints 12 , waterproofing material for the vertical joints 12 a , and joint material 13 This coating prevents direct sunlight from hitting the surface, improves weather resistance, and helps maintain performance over the long term. To explain more specifically, Figure a shows a decorative surface 9, a decorative side surface 10 whose both edges are bent inward at an angle θ ₃ (acute angle), and an engaging tongue piece 11 whose lower end is bent inward and extended. Fig. b shows a joint cover with the decorative side surface 10 formed into a dogleg shape and the engaging tongue piece 11 removed, and Fig. c shows the joint cover shown in Fig. b with the tip of the decorative side surface 10 removed. The joint cover is formed with a stable tongue piece 11a that bends toward the direction and extends horizontally, and its edge is bent inward. Figure d shows the joint cover with the tip of the decorative side surface 10 bent inward. Figure e shows the decorative side surface. 10 is formed vertically, and the tip thereof is bent inward and extended horizontally, and then formed into an upward dogleg shape. Further, the width W ₃ of the decorative surface 9 is determined by the width W ₂ of the fixture 4 , the interval W ₄ between the engaging tongues 11, and the interval W ₅ between the tips of the decorative side 10, and the length L ₂ is 600~ It is about 7272mm. The vertical joint 12 includes the fixture 4 , the cover 8 , and the vertical joint part 12a.
In the vertical joint part 12a, the end surfaces of the panel 1 in the length direction are made to face each other on the pillar 16 or the stud 17 with a gap ΔW, and the end of the panel 1 is connected to the nail 1.
4 and formed vertically, the end faces of panel 1 are almost butt-like, and the gap ΔW is approximately 1 to 5 mm, including cutting errors and installation errors of the end faces of panel 1 . . That is, the end face of the panel 1 is attached so as to function as a guide when attaching adjacent panels 1 . The joint material 13 fills the gap between the vertical joints 12a, which is formed by the end faces of the panel 1 facing each other, and closes the gap, so that rainwater and the like can leak into the inside of the panel 1 and This is to prevent it from entering the frame 15. The joint material 13 is made of one or more of synthetic resin, silicone, cement, and rubber materials, and is waterproof and fluid enough to be easily injected into the vertical joints 12a during filling. It has a certain degree of cushioning properties after curing. Next, to explain the joint structure according to the present invention, first, the panel 1 shown in FIG. 2a is placed on the frame 15.
The male connecting portions 2 of are each fixed onto the frame body with nails 14. Therefore, in order to form the first row of horizontal wall portions A, the above-described operations may be repeated from the base to the girder. At this time, the ends of the panel 1 in the longitudinal direction are always placed on the main pillars 16 or the studs 17 to fix the ends of the panel 1 to the frame 15. Next, in order to form the second row of horizontal wall parts B on the end face of the wall part A, the above process is performed while abutting the end face of the panel 1 against the end face of the wall part A with a gap of approximately 5 mm. Repeat this to form the second row of horizontal wall portions B. Vertical joint portions 12a are sequentially formed by repeatedly constructing such horizontal wall portions in the portions that will become the outer walls of the building. Next, fill the gap between the vertical joints 12a with a silicone joint material 13, and place the fixture 4 on top of the silicone joint material 13 so that the center of the bottom surface 5 of the fixture 4 almost coincides with the vertical joint 12a, and attach the tip of the leg 6 to the panel 1. and fixed it to the frame 15 with nails 14. Next, as shown in FIG. 5 , the lower end of the decorative side of the joint cover 8 is locked to the fixture 4, and the joint cover 8 is elastically deformed and engaged by pressing in the direction of the arrow. A vertical joint 12 is formed by covering the nail head and fixture 4 with a joint cover 8 . In the vertical joint 12 of such a structure,
Since it has two waterproof structures, the joint cover 8 and the joint material 13 , sufficient waterproofness can be achieved without using a large amount of caulking agent as in conventional methods. Since it is coated with water, it can prevent deterioration caused by ultraviolet rays, etc., and maintain its waterproof properties over a long period of time. Furthermore, since the joint cover 8 is fixed with a plurality of fixtures, even if one part of the joint is disengaged, the joint cover 8 will not come off in a chain reaction and the joint cover 8 will not fall off. be. What has been described above is only one embodiment of the joint structure according to the present invention, and as shown in FIG .
It is also possible to have a joint structure in which the joint material 3a is planted and a fluid joint material 13 is injected thereon. Furthermore, although not shown, a waterproof sheet, metal foil (Al, Pb), and heat insulating material (single or composite) are provided between the frame 15 and the panel 1.
It is also possible to intervene. As described above, according to the joint structure according to the present invention, the vertical joint formed at the end of the panel does not appear directly on the outside, so high precision is not required in the construction of the panel, and therefore the construction time is significantly reduced. There are features that allow it. In addition, the panel is fixed by nailing the longitudinal ends, placing the mounting hardware on top of it, and driving it into the frame with nails, which makes the integration of the panel and frame strong. There are advantages. Furthermore, since the nail heads driven into the edges of the panels are not visible at all, there is no need to apply a decorative coating to areas including vertical joints.
In addition to being low cost, it also has the feature that it does not cause mottled patterns on the wall due to differences in color. In addition, since the vertical joints are covered with joint material, fixtures, and joint covers, they have excellent waterproof and weather resistance. Furthermore, since the joint material is covered with a joint cover, deterioration due to ultraviolet rays and the like can be suppressed, and performance can be maintained over a long period of time. In addition, since it has two waterproof structures: waterproofing by covering the joint cover and waterproofing by filling the joint material,
A feature of this method is that it does not require the use of large amounts of joint material as in the past. Furthermore, since the joint cover is fixed with a plurality of fixtures, it has the characteristic that it is difficult to fall off. Furthermore, since the joint cover can be easily replaced, there is an advantage that even when the wall is completely coated with paint and repaired, a joint cover that matches the color can be attached. In addition, place the legs of the fixture on the panel surface,
Since the bottom part is fixed to the frame with nails, there is no deformation.
It is robust and securely supports the panel by pressing the edge of the panel, and has the characteristics of correcting deformations on the panel surface, such as peaks and valleys.
