JPH09195396A - Connecting water drip metal fitting of vertically stretched exterior wall board - Google Patents

Abstract

PROBLEM TO BE SOLVED: To enhance workability and waterproofness at upper and lower connecting areas of a vertically stretched exterior wall board. SOLUTION: A plastic deformable contact piece 36, which is L-shaped in a cross section, is formed on the rear surface of a decorated area 32 of a connecting water drip metal fitting 31. During construction time, the contact piece 36 is loaded on the upper end face of an exterior wall board 26, thereby securing a horizontal level of the connecting water drip metal fitting 31 with ease and accuracy and eliminating the need for a conventional marking practice of a mounting position. In addition, the contact piece 36 comes i contact with the upper end face of the exterior wall board 26 on the rear surface side of the decorated area 32 and produces a sealed state, which prevents the penetration of rainwater blown up with wind from the clearance between the decorated surface area and the exterior wall board 26. When a clearance dimension between exterior wall board 26 is reduced if a post material 23 is subjected to compression deformation with a load after construction, the contact piece will be elastically deformed upward accordingly, thereby preventing a large compression stress from acting on the vertical joining areas of the exterior wall board 26 and eliminating the generation of a phenomenon that the wall surface swells to the outdoor side.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint for draining a vertically stretched outer wall plate which is mounted so as to cover a gap between vertically vertically adjacent outer wall plates.

[0002]

2. Description of the Related Art Conventionally, there are two methods of constructing a ceramic-type exterior wall panel, namely, a vertical installation method in which a vertically long external wall panel is attached to a wall surface, and a horizontal application method in which a horizontally long external panel is attached to a wall surface. In addition, since many wall patterns have a horizontally long block pattern such as a tile-like or brick-like pattern, in recent years, a horizontal stretching construction that can construct a horizontally long block pattern without a sense of incongruity has been often adopted.

However, in this horizontal stretching, since the joint joints on the left and right sides of the outer wall plate are filled with caulking to take waterproof measures, the sealability of the joint joint is deteriorated due to deterioration of the caulk and aging shrinkage and deformation of the outer wall plate. , Which can lead to rainwater intrusion. In addition, in this horizontal stretching construction, since the upper and lower joints of the outer wall plate are made by fitting the male and female real parts, when the pillar material to which the outer wall plate is attached is compressed and deformed by the load of the building itself or housing equipment etc. However, it is difficult to relieve the compressive stress acting on the upper and lower joints of the outer wall plate, and when the compressive stress is increased, the wall surface swells outward.

[0004] Under these circumstances, recently, vertical construction has been reviewed. In this vertical stretching, the left and right sides of the outer wall plate are joined by fitting the male and female real parts, and the upper and lower sides of the outer wall plate are joined using a joint drainage fitting. A conventional vertical joining structure is disclosed in Japanese Utility Model Laid-Open No. 56-148411 (Fig. 9).
As shown in (1), after the construction of the lower outer wall plate 11, the joint draining metal fitting 12 is directed to the front surface of the upper end portion of the lower outer wall board 11 and the joint draining metal fitting 12 is attached to the lateral furring strip 14 with the nail 13. After hitting, after that, the outer wall plate 15 on the upper side is attached to the joint draining metal fitting 12. In this configuration,
By providing a gap between the upper and lower outer wall plates 15 and 11, even when the pillar material is compressed and deformed by the load after construction, the gap size between the upper and lower outer wall plates 15 and 11 only becomes smaller. The compressive stress does not act at all between the outer wall plates 15 and 11, and the phenomenon that the wall surface bulges to the outside does not occur.

[0005]

However, the above-mentioned conventional vertical joining structure has the following two drawbacks. (1) The attachment of the joint drainer 12 is troublesome. That is, in order to secure the horizontal level of the joint drainage fitting 12, it is necessary to mark the mounting position in advance. While aligning the joint drainage fitting 12 based on this marking,
The joining drainer 12 must be installed.

(2) Waterproof measures are insufficient. That is, since the surface of the outer wall plate 15 is formed with a concavo-convex pattern, a gap is created between the joint draining fitting 12 and the surface of the outer wall plate 15, and rainwater blown up by the wind enters from this gap. . In addition, since the left and right joints of the outer wall plate 15 are formed in a groove shape, a gap is also formed between the joint and the joint drainage fitting 12, and rainwater blown up by wind enters from the gap. .

The present invention has been made in consideration of such circumstances, and therefore an object thereof is to be able to easily attach a joint draining metal member, improve workability, and improve waterproofness. It is to provide a joint draining metal fitting for a vertically stretched outer wall plate capable of performing the above.

[0008]

In order to achieve the above-mentioned object, a joining draining fitting for a vertically-extended outer wall plate according to the present invention comprises a decorative surface portion for covering a front surface of an upper end portion of a lower outer wall board and an upper outer wall board. A mounting piece fixed to the base material on the back side, a plate receiving section for receiving the lower end surface of the upper outer wall plate, and a connection between the lower end of the plate receiving section or the mounting piece and the upper end of the decorative surface section It is configured to have a slanting surface portion that is lowered frontward and an elastically deformable contact piece portion that projects toward the back surface side of the decorative surface portion and contacts the upper end surface of the outer wall plate below.

In this joint draining fitting, since the elastically deformable abutment piece on the back side of the decorative surface abuts the upper end surface of the lower outer wall plate and seals it, the abutment piece is used. It is possible to prevent rainwater from entering. Also, at the time of construction, by placing the contact piece on the upper end surface of the lower outer wall plate,
The horizontal level of the joint drainage is easily and accurately secured,
This eliminates the need for marking the mounting position as in the related art. After the installation, if the column material is compressed and deformed by the load and the gap between the upper and lower outer wall plates becomes smaller, the contact piece is pushed up at the upper end surface of the outer wall plate and elastically deformed upward, accordingly. A large compressive stress is prevented from acting on the upper and lower joints of the outer wall plate, and the phenomenon that the wall surface swells to the outdoor side does not occur.

[0010]

DETAILED DESCRIPTION OF THE INVENTION A first embodiment of the present invention will be described below with reference to FIGS. First, FIG. 3 and FIG.
The structure of the entire wall will be described based on. A pillar member 23 and a stud member (not shown) are erected on a concrete foundation 21 via a base 22. A waterproof sheet 24 is attached to the pillar member 23 and the stud member, and a horizontal furring strip 25 is nailed from above as a base material. A vertically long outer wall plate 26 is stuck to the horizontal body edge 25 by vertical stretching. An uneven pattern is formed on the surface of each outer wall plate 26.

The outer wall plate 26 is attached as shown in FIG.
Construction of metal fittings using fastening metal fittings 27 or horizontal furring 25 with nails 28
Either of the nailing constructions for driving to can be adopted. The left and right joint structure of each outer wall plate 26 is such that the male and female real parts 29 and 30 formed at the left and right ends are fitted to each other, and the fastening metal fitting 27 or the nail 28 is used.
It is fixed with.

The length of the outer wall plate 26 in the vertical direction is 2.7 m to 3.0 m, which corresponds to the height of the first floor of the building. Therefore, when the wall surface has a height of two or more stories, the wall surface of the first floor is high. After constructing, the wall surface on the second floor is constructed. At this time, the outer wall board 26 on the first floor
The joint drainage fitting 31 is attached so as to cover a gap between the outer wall plate 26 and the outer wall plate 26 on the second floor.

The vertical joining structure of the outer wall plate 26 will be described below with reference to FIGS. 1 and 2. The upper and lower joints of the outer wall plate 26 are provided with a gap of, for example, about 5 mm to 8 mm. The joint draining fitting 31 that covers this gap is formed by extrusion molding of a metal such as aluminum, and the decorative surface portion 32 that covers the front surface of the upper end portion of the lower outer wall plate 26.
A mounting piece 33 that is fixed to the horizontal furring strip 25 by screws 38 or nails on the back surface side of the upper outer wall plate 26; and a plate receiving portion 34 that receives the lower end surface of the upper outer wall plate 26. An inclined front surface 35 that connects between the lower end of the mounting piece 34 and the upper end of the decorative surface portion 32, and an elastically deformable cross section that projects toward the rear surface of the decorative surface portion 32 and contacts the upper end surface of the lower outer wall plate 26. The L-shaped contact piece portion 36 is integrally formed. The gap between the plate receiving portion 34 and the abutting piece 36 determines the gap size between the upper and lower joints of the outer wall plate 26. As shown in FIG. 2, a fixing screw hole 3 for inserting a screw 38 into the mounting piece portion 33.
7 are formed.

As shown in FIG. 3, the procedure for constructing the outer wall plate 26 is as follows. First, as shown in FIG. 3, the joint draining metal fitting 31 is horizontally fixed to the horizontal furring strip 25 of the base 22 with screws (the base water draining metal fitting shown in FIG. 31 should be used). After that, the outer wall plate 26 is attached to the horizontal furring strip 25 on the wall surface of the first floor of the building using the fastening metal fitting 27 or the nail 28 by the vertical tensioning method (see FIG. 5). At this time, by mounting the lower end of the outer wall plate 26 on the plate receiving portion 34 of the joint draining fitting 31, the height position of the outer wall plate 26 can be accurately and easily positioned.

After the outer wall plate 26 is vertically stretched on the wall surface of the first floor of the building in this manner, the joint draining fitting 31 is attached to the joint portion of the wall surfaces of the first and second floors as follows. First,
As shown in FIG. 1, the contact piece portion 36 of the joint drainage fitting 31 is placed on the upper end surface of the outer wall plate 26, and in this state, the decorative surface portion 3
2 is placed on the front surface of the upper end portion of the outer wall plate 26, and the attachment piece portion 34 is placed on the lateral furring strip 25. At this time, by placing the contact piece 36 on the upper end surface of the outer wall plate 26, the horizontal level of the joint drainage bracket 31 can be easily and accurately secured, and the marking of the mounting position as in the related art is unnecessary. Becomes

Then, with the mounting piece portion 34 facing the lateral furring strip 25, a screw 38 or a nail is inserted into the fixing screw hole 37 of the mounting strip portion 34 and fixed to the lateral furring strip 25. After this, the outer wall plate 26 is attached to the horizontal furring strip 25 on the wall surface of the second floor of the building using the fastening metal fitting 27 or the nail 28 by the vertical tensioning method. At this time, the lower end of the outer wall plate 26 is attached to the plate receiving portion 3 of the joint drainer 31.
By mounting it on the outer wall plate 4, the height position of the outer wall plate 26 can be accurately and easily determined. The outer wall board 26 may be stretched vertically on the third and higher floors in the same manner using the joint drainage fitting 31.

In the vertical joint structure of the outer wall plate 26 described above, the abutting piece portion 36 of the joint drainage fitting 31 is placed on the upper end surface of the outer wall board 26, so that the horizontal level of the joint drainage fitting 31 can be easily and accurately determined. Therefore, the marking of the mounting position unlike the conventional case becomes unnecessary, and the joint draining metal fitting 31 can be mounted extremely easily, and the workability can be improved.

Moreover, since the elastically deformable abutment piece 36 of the joint draining fitting 31 abuts on the upper end surface of the outer wall plate 26, the abutment piece 36 on the back side of the decorative surface portion 32 causes the abutment piece 36 to the upper end surface of the outer wall plate 26. The gap between and is sealed. Thereby, infiltration of rainwater blown up by the wind from a gap between the decorative surface portion 32 and the surface uneven pattern of the outer wall plate 26 and a gap between the decorative surface portion 32 and the left and right joint joints of the outer wall plate 26 (see FIG. 5). The contact can be prevented by the contact piece 36, and the requirements for improved waterproofness and durability can be satisfied.

Further, since the abutting piece portion 36 abutting on the upper end surface of the outer wall plate 26 is elastically deformable, the column member 23 after the construction.
When the gap size between the upper and lower outer wall plates 26 is reduced by compressive deformation due to the load of the building or the like, the contact piece 36
Is elastically deformed upward so as to be pushed up by the upper end surface of the outer wall plate 26. Due to the elastic deformation of the contact piece 36, a large compressive stress is prevented from acting on the upper and lower joints of the outer wall plate 26, and the phenomenon that the wall surface swells to the outside does not occur.

Further, in the second embodiment shown in FIG. 6, in order to improve the appearance and design, a horizontally long decorative curtain plate 39 is provided above the joint draining fitting 31 provided at the upper and lower joints of the outer wall plate 26. Place the nail 40 on the front surface of the lower end of the outer wall plate 26.
It is fixed by hitting with.

In the first and second embodiments described above, as shown in FIG. 7 (a), the joining drainage fitting 31 is a metal extruded product, and the contact piece 36 is formed in an L-shaped cross section. However, like the joint draining metal fitting 41 shown in FIG. 7B, a metal extruded product is used to form the contact piece portion 42 in the form of an inclined surface which is inclined downward, and the tip of the contact piece portion 42 is formed into an outer wall plate. You may make it contact | abut with the upper end surface of 26.

Further, the present invention is not limited to the one in which the joint drainage metal fitting is integrally formed by extrusion molding of metal, and the joint water drainage metal fitting may be formed by bending the metal plate. In this case, for example, it may be bent into the shape shown in FIGS. In FIG. 8, in the joint draining metal fittings 43, 44 of (a) and (b), the contact piece portion 47 is bent into an L-shaped cross section, and the joint draining metal fittings 45, 46 of (c) and (d) are The contact piece portion 48 is formed in the shape of a slope that is inclined downward. Further, the joint draining metal fittings 43 and 45 of (a) and (c) are formed by horizontally folding back the plate receiving portion 50 below the mounting piece portion 49, and the joint draining metal fittings of (b) and (d). In the plates 44 and 46, the plate receiving portion 51 is bent and formed in a step shape. In each of the joining drainage fittings 43 to 46, a bead portion in which an upper end portion of a mounting piece portion 49 is bent toward the outer wall plate side (left side in the drawing) and an intermediate portion of the mounting piece portion 49 projects toward the outer wall plate side. 52 is formed, and slopes 54 and 55 are formed between the attachment piece 49 or the plate receiving portion 51 and the decorative surface portion 53. In addition, each joint draining fitting 43
The decorative surface portions 53 to 46 are doubled by folding back at the lower end to form the contact piece portions 47 and 48.

[0023]

As is apparent from the above description, according to the joining drainer of the vertically-extended outer wall plate of the present invention, since the elastically deformable abutting piece projecting to the rear surface side of the decorative surface portion is provided, By placing this contact piece on the upper end surface of the outer wall plate, it is possible to easily and accurately secure the horizontal level of the joint draining metal fitting, which can improve the workability and contact the back surface side of the decorative surface part. One part can prevent the infiltration of rainwater and improve the waterproof property. In addition, since the contact piece is elastically deformed in accordance with the compressive deformation of the column material, a large compressive stress can be prevented from acting on the upper and lower joints of the outer wall plate, and the phenomenon that the wall surface swells to the outside can be avoided. .
