Description

[Detailed Description of the Invention] The present invention relates to a joint structure of a wall formed using panels.

Generally, when panels are used to form a wall, such as a horizontally extending exterior or interior, the structure of the joints between the panels, the so-called joints, becomes a major problem from the standpoint of waterproofing, appearance, and construction. was. That is, there was a drawback that the fasteners for fixing the panel, such as nail heads, were directly exposed to the exterior of the panel end. In addition, in terms of waterproofing, there was a disadvantage that rainwater leaked to the back side of the wall from the nail heads and the butt joints of the panels. Furthermore, Utility Model Publication No. 54-26647 is known as an improvement on this type of alignment. Moreover, with this structure, not only is it not easy to process the clips, but there is also a large amount of wasted material, and there are no waterproof tongues at both longitudinal ends of the band-shaped seat plate, causing rainwater to leak to the back surface of the wall. Since the gassho claw has a shape that allows for easy elastic deformation, the band-shaped cover can be easily removed. Since a large gap is required between the ends of the outer wall panels, especially a gap where the gassho claws can be deformed, the insulation of the joints is poor. Machining is required at the edge of the exterior plate. There were drawbacks such as:

In order to eliminate these drawbacks, the present invention includes, for example, a locking body made of a single plate with a simple T-shaped cross section, a cover with a mating claw that strengthens the engagement force, and a long panel. The insertion part of the locking body is made to protrude from the wall surface, and the upper part of the rising part is made thinner than the lower part to facilitate cover installation. A strengthened guide, which also serves as a joint spacer, makes contact with the lower part of the rising part to maintain a constant width, and the mating claw of the cover is fitted deeper and more securely into the insertion part of the locking body to prevent the cover from coming off. Furthermore, the present invention proposes a wall joint structure in which the gap between the locking body and the end face of the panel is filled with a sealing material to close the gap, thereby greatly improving the waterproof and heat-insulating properties of the joint.

An embodiment of a wall joint structure (hereinafter simply referred to as a joint) according to the present invention will be described in detail below with reference to the drawings. 1A and 1B are cross-sectional views showing the above-mentioned joints, 1 is a locking body, 6 is a cover, 10 is a panel, 12 is a frame, 13 is a fixing device, such as a nail,
14 is a sealing material. To explain further, the locking body 1 is made by extruding a long body, such as a metal plate, a synthetic resin plate, etc. as shown in FIG. The vertical section is formed into a substantially T-shape by processing methods such as pressing and roll forming, and is mainly useful as a waterproof base material, a partition wall, a guide, an attachment part to a building frame, and a locking part. That is, the locking body 1 has a stepped rising part 3 (hereinafter simply referred to as the rising part) provided at the center of the short surface 2a of the horizontal surface part 2 of the elongated body along the longitudinal direction, and a stepped rising part 3 (hereinafter simply referred to as the rising part) provided at the tip thereof. It is formed from a fitting part 4 and a tongue piece 5 which is formed by bending or shaping the longitudinal edge of the horizontal surface part 2 into a lower seam shape. To explain further, the rising part 3 is formed of a lower part 3a with a thickness t ₁ considering the width of the guide/joint spacer, reinforcement, and fitting claw, and an upper part 3b with a thinner thickness t ₂ . panel 10
In addition to keeping the width of the joint 11 constant during installation, the panel 10 can be supported with sufficient strength to cope with pressure, etc. during construction, and the lower end of the mating claw (described later) contacts the panel edge of the joint 11. This helps prevent the engagement force from being reduced. Height of the lower part 3a above
h ₁ is smaller than the thickness T of the joint end of the panel 10 by Δh, and the height h ₂ of the upper portion 3a is approximately equal to or somewhat larger than Δh. Further, the insertion part 4 may be solid or hollow, and its cross section may be diamond-shaped, square, or (not shown) wedge-shaped, semicircular, or oval, which can be inserted to make it as difficult as possible to remove the cover to be described later. Good to have. In addition, in the case of the locking body 1 shown in figure b, the horizontal surface part 2 and the rising part 3 are divided into two parts,
It is formed from a single plate, and is the same as the horizontal surface portion 2 as a whole. The height H of the locking body 1 is such that at least a large part of the height _h3 of the insertion part 4 protrudes from the thickness T of the joint end of the panel 10. In addition, the cover 6 is shown in Fig. 3 a and b.
As shown in figure b, a long elastic body such as a metal plate (color steel plate, PVC steel plate, aluminum plate, stainless steel plate, copper plate, etc.), synthetic resin plate, etc. can be extruded, drawn, or injection molded, or as shown in figure b. The vertical cross section is formed into a gutter-like shape consisting of a top surface 7 and side surfaces 8 by a processing method such as pressing or roll forming, and a fitting claw 9 is formed by protruding along the longitudinal direction at the center of the back surface 6a. be. To explain further, the cover 6 mainly attaches to the joint part 11, the end part of the panel 10 forming the joint part 11, and the head of the fixing tool 13, which is hammered into the end part of the panel, to complete the installation of the entire wall. After washing, it functions as a cover, a decorative surface, and a waterproof surface. Further, to explain a specific example, the angle θ of the side surface 8, the so-called height _h4 , is determined by the position and size of the fitting part 4 of the locking body 1 , and the cross-sectional shape of the fitting claw 9 is determined by the above-mentioned position and size of the fitting part 4 of the locking body 1. It has a shape that substantially corresponds to the insertion part 4, and a V-shaped guide tongue piece 9a is formed at the entrance portion thereof to facilitate fitting. Also, the height _h5 is about _h4 - (thickness t of the long body),
Or it is a size added to this size. The above-mentioned panel 10 forms a wall by connecting a plurality of panels, and its structure includes a single panel,
Any composite board, sanderch board, etc. may be used, and the board thickness T is the height of the rising part 3 of the locking body 1 h ₁ + h ₂
The dimensions are equal to or smaller than this. In addition,
The plate thickness T is such that the end portion forming the joint portion 11 is at least equal to or smaller than the height h ₁ +Δh of the rising portion 3, and only the end portion is lower than the other surface as shown in Fig. 4. It also includes formed panels. Further, the sealing material 14 is applied to at least the end surface 10a of the panel 10 of the joint portion 11 as shown in FIG.
and the gap 1 formed between the upper part 3b of the rising part 3

It is in the form of a sticky jelly. The materials include sealing materials, caulking materials, waterproofing materials,
These include adhesives (including hot melt type), putty materials, fireproof putty materials, sealants, packing materials, etc. The materials include organic materials, inorganic materials,
Or it consists of a composition that is a mixture of these.

Next, to explain a construction example, first, a plurality of locking bodies 1 are arranged on the frame 12 at pitches corresponding to the length of the panel 10, at positions that will be the so-called joint parts 11, and the horizontal surface parts 2 are fixed with nails. 13. Next, place the end of each panel on the surface of the horizontal surface part 2, and hit this part with a nail 13 to the top of the panel 1.
Fix 0 respectively. In addition, at this time, panel 10
The end surface 10a of the locking body 1 is arranged in direct contact with the side surface 3b of the lower part 3a of the locking body 1. Next, a sealing material 14 is placed in the gap 15, for example, a pressure-sensitive hot melt adhesive is applied using a nozzle (not shown) to close the gap 15. Therefore, the fitting claw 9 of the cover 6 is fitted into the fitting part 4 through its elastic deformation, the cover 6 is fitted into the joint part 11, and the nail head exposed at the panel end of the joint part 11 is fitted. The gap between the joint and the fitting part 4 is covered. Therefore, in order to form the entire wall, the above-mentioned operations may be repeated in sequence at the areas corresponding to the joints.

What has been described above is only one embodiment of the joint according to the present invention, and the locking body 1 may be formed as shown in FIGS. 6a to 6g, and the cover 6 may be formed as shown in FIGS. It can also be formed as shown in Figures a to p.
Although not shown, the cover 6 can also be formed from an embossed plate. In addition, it is also possible to lay a waterproof sheet such as asphalt felt on the entire surface of the frame 12 or in a range that covers the joint portions 11.

As described above, in the joint according to the present invention, since the insertion part is made to protrude from the panel surface, the gap between the panel end face and the rising part of the locking body can be minimized, and the joint has a feature that it can have a structure with high heat insulation properties. In addition, when constructing the panel, the rising portion of the locking body can be used as a guide, so there is no need to be careful about the spacing between joints, and the panel is characterized by excellent workability. Furthermore, since the cover protrudes from the wall surface and is fitted into the fitting part where the upper part of the rising part is narrower than the joint part, it is easy to fit and moreover, it can be fitted reliably.
In addition, the fixing tool exposed on the surface of the joint end of the panel and the joint can be covered with a decorative cover to create a beautiful appearance. In particular, since a gap is formed between the upper part of the rising part of the locking body and the end face of the panel, and the sealing material is planted in this space, the sealing material can be installed easily and reliably, thereby improving the waterproofness and heat insulation of the joint area. It has features that can significantly improve In addition, the locking body and cover have a simple structure and can be manufactured at low cost. Another feature is that when the lower part of the rising part of the locking body is hollow, the vertical connection can be made by simply cutting out the lower part.
