Description

[Detailed description of the invention] [Industrial application field] When forming internal and external walls using horizontal drywall material (hereinafter simply referred to as wall material), the present invention is applicable to the longitudinal joints of the wall material, This invention relates to a jointer for vertical joints (hereinafter simply referred to as jointer) that serves as a decorative and waterproof material for so-called vertical joints. [Prior Art] Generally, when a wall material is used to form a horizontal wall, for example, an end-wall wall, a so-called joint is formed, where the ends of the wall material face each other. It is common for concrete to be cast as a waterproof and decorative material. In other words, the joints used conventionally are fixed by laying a joint with a width wider than the joint width and driving a nail through the top of the joint, or by pulling the lower end of the joint into a wall material or horizontal joint. Generally known are jointers in which the upper end is fixed with nails or the like from above the wall material, or those in which joint material is simply filled into the joint gaps. [Problems to be solved by the invention] However, when vertical joints are formed as described above, fixing tools such as nails are exposed on the decorative surface, spoiling the aesthetic appearance, being inferior in waterproofness and workability, and causing problems such as earthquakes. There was a risk that the cover would come off. In addition, the jointer attached to each stage of the armor tension,
The installation of the jointer had to be done at the same time as the construction of the first stage of wall material, which had the disadvantage of poor workability. [Means for solving the problem] In order to eliminate these drawbacks, the present invention has a cover decorative surface that has the same shape as the decorative surface of the wall material, and prevents the horizontal line of the wall from breaking midway. In order to prevent this and improve the aesthetic appearance, one end of the cover decorative surface is
A fixing part that protrudes upward and has a width narrower than the decorative surface of the cover is formed, and a locking part with a locking piece that protrudes inward is formed at the other end to prevent the jointer from coming off and to prevent the nail head from coming off. This project proposes a construction method that improves workability by preventing the exposure of wall materials and by attaching them after the wall material has been constructed. [Embodiment] A typical embodiment of the present invention will be described in detail below with reference to the drawings. Fig. 1 is a perspective view showing the above-mentioned jointer 1 , which is made of metal plates (color steel plates, PVC steel plates, aluminum plates, stainless steel plates, copper plates, clad steel plates, sand German steel plates, etc., including embossed plates) or synthetic resin plates. It is formed by roll molding, extrusion molding, injection molding, press molding, etc. That is, the jointer 1 is formed from a cover decorative surface 2 , a fixing portion 5 , and a locking portion 8 . This cover decorative surface 2 covers the edges of the vertical joints of the decorative surface B of the wall material A as shown in FIG. 2, for example, and covers the longitudinal joints of the wall material A to prevent rainwater. This prevents infiltration into the inside of the wall. Its shape is based on the shape of the decorative surface B of the wall material A. For example, as shown in Fig. 2, the decorative surface B is a wall with an overlay type, that is, a wall in which the decorative surface B consists of an inclined decorative surface B ₁ and a stepped decorative surface B ₂ . When using material A, a slope 3 covering slope decorative surface B ₁ ,
It is composed of a stepped surface 4 covering a stepped decorative surface _B2 . Of course, the length l ₁ of the slope 3, the length l ₂ of the stepped surface 4, and the angle θ ₁ between the slope 3 and the stepped surface 4 are the length l ₃ of the sloped decorative surface B ₁ of the wall material A, and the length of the stepped decorative surface B _2. The length l ₄ and the angle θ ₂ between the inclined decorative surface B ₁ and the stepped decorative surface B ₂
The relationships are as follows: l ₁ ≒ l ₃ , l ₂ ≒ l ₄ , and θ ₁ ≒ θ ₂ . This allows the horizontal lines formed on the wall by wall material A to be formed without separating them with vertical joints.
This relationship allows for the formation of a wall with rich design. The fixing portion 5 is formed from a nailing piece 6 that projects upward near the center of the upper edge of the slope 3, and a tongue piece 7 that is bent at the tip of the nailing piece 6 into a seam shape. To explain in more detail, the nailing piece 6 is a part that is fixed to the wall base with fixing tools such as nails in a position where rainwater does not enter.The width of the cover decorative surface 2 is W, and the width of the nailing piece 6 is _W1. , If the width of the sill plate r shown in Fig. 3, that is, the width of the vertical joint, is W ₂ , then W>
The relationships are W ₁ , W>W ₂ , and W ₁ ≦W ₂ . Locking part 8
The locking piece 9 has the lower end of the step surface 4 bent inward by approximately 90 degrees, and the tongue piece 1 provided at the tip and both ends of the locking piece 9.
0, and its width is _W3 , length _l5 , and depth of fitting groove _B3 of wall material A is _l6 , then W≧
The relationships are such that W ₃ , W ₂ <W ₃ , and l ₅ ≦l ₈ , so that it can be reliably inserted into and engaged with the fitting groove B ₃ of the wall material A on both sides of the vertical joint. In addition, it is also possible to provide a flap-like tongue piece 11 at the end of the cover decorative surface 2 in the short direction, as shown in the figure, to improve the strength of the jointer 1 and the safety during construction. be. Also wall material A
is horizontally stretched, and the material is not limited. Next, a construction example will be briefly explained. Now the second
When a wall is formed using wall material A as shown in the figure, and vertical joints as shown in Figures 3 and 4 (cross-sectional view of Figure 3) are formed using jointer 1 shown in Figure 1. Assume. First, a cross-shaped slat board r is placed and fixed at the vertical joint formation position of the wall base α (only the studs are shown in the figure) consisting of studs, rims, waterproof sheets, etc.
This siding board r serves as a waterproof base for the vertical joints and also serves as a guide when installing the wall material A. Next, wall material A is placed on both sides of the paving board r from the base to the girder, or depending on the type of wall material A, from the girder to the base to form a wall surface. Next, from the bottom of the vertical joint, cover the decorative surface B of the wall material A with the decorative surface 2 of the cover, insert the locking part 8 into the fitting groove B ₃ of the wall material A, and push the jointer 1 upward. and engage the nailing piece 6 with the plinth plate r.
and fix it with nail β. In this way, vertical joints in the wall are formed by attaching jointers 1 from the lower stage to the upper stage. In addition, the paving board r
