Description

TECHNICAL FIELD The present invention relates to a covering frame that holds the edges of a covering sheet material covering a base surface, and a method of using the covering frame.

Conventionally, a method of using a wall mounting member is known (Patent Document 1).
This method of using a wall mounting member includes a base plate that is attached to a wall of a building, and a pair of standing plates that are formed to rise from the base plate, and that the tips of the standing plates are approximately The pair of upright plates are bent in a U-turn shape and elastically pressed to contact each other, forming a wave-shaped uneven surface on the cross section of the tip of the pair of upright plates, and forming recesses in each of the pair of uneven surfaces. and the convex portions are formed so as to engage and contact each other, and the pair of upright plate portions are made alternately with cuts extending to the base plate portion at intervals in the length direction, so that the plate portions can be bent freely along the wall surface. The wall mounting member formed in the above-mentioned shape is bent along the wall surface and attached to the wall surface, and a functional material having the same thickness as the height of the wall mounting member is placed on the inner and/or outer wall surface of the bent wall mounting member. The peripheral edge of the wall cover sheet material is sandwiched and locked between a pair of corrugated concave and convex surfaces of the tip portions of the wall mounting member that are pressed against each other and brought into contact with each other.

However, in the method of using the wall mounting member described in Patent Document 1, when installing the wall surface of a building, the wall surface cover sheet material is sandwiched between the tips of the wall mounting member. When adjusting the position of the material (if the wall cover sheet material is cloth or the like, adjusting the grain curvature, etc.), there is a problem that the force for pinching and locking the wall cover sheet material is too strong, making it difficult to adjust the position.
Furthermore, in the method of using the wall mounting member of Patent Document 1, depending on the thickness of the wall cover sheet material (for example, when the wall cover sheet material is thin), the force for clamping and locking the wall cover sheet material is not sufficient.

In view of these points, the present invention sets the resistance load when sliding the sandwiched facing sheet material in the longitudinal direction of the frame to 60 N/100 mm or less, and reduces the resistance load when sliding the sandwiched facing sheet material in a direction substantially perpendicular to the frame.

This is a step of pinching the ends of H (see FIG. 4(b)).
In this temporary fixing step P1, the facing sheet material H is slid along the longitudinal direction L of the facing frame body 1 with the facing frame body 1 sandwiching the end portion of the facing sheet material H having a predetermined thickness. It can be said that it is possible (easy to slide along the longitudinal direction L), and positional adjustment such as adjustment of the cloth grain M can be facilitated. In addition, when the facing sheet material H is a cloth, the grain M means the direction of the design, the warp direction and the weft direction of a woven or knitted material, and when the facing sheet material H is a synthetic resin film, etc. In the case of a sheet-like object, it means the direction of the design (see FIG. 4(b), etc.).

<Main fixing process P2>
As shown in FIG. 5, in the case of the facing frame 1 of the first embodiment, the main fixing process P2 is performed after the temporary fixing process P1 of the first embodiment, the tongue piece 4a on the facing side and the tongue piece on the back side. This is a step of sandwiching the edge of the facing sheet material H between the piece 4b and the edge plate 5 (see FIG. 5(a)), and if it is the facing frame 1 of the second embodiment, the second embodiment After the form temporary fixing step P1, the end of the facing sheet material H is formed between the one tongue piece 4Aa on the facing side and the one tongue piece 4Ab on the back side, the other tongue piece 4Ba on the facing side and the other tongue piece 4Bb on the back side. (see FIG. 5(b)).
In the main fixing process P2, in the temporary fixing process P1, the facing sheet material H is fixed in the longitudinal direction L of the facing frame 1 with the facing frame 1 sandwiching the end portion of the facing sheet material H having a predetermined thickness. It can be said that this is a process of sliding along the direction R that is substantially orthogonal to , and further pushing it in, and it can also be said that it is difficult to slide it along the direction R that is substantially orthogonal to the . As shown in FIG. 5, the "substantially orthogonal direction R" in the present invention refers to a direction substantially orthogonal to the longitudinal direction L of the mounting frame 1 and on the facing side surface (exposed surface) of the facing sheet material H. Even if the direction R1 is approximately along the direction R1, or the direction (normal direction) R2 is approximately perpendicular to the longitudinal direction L of the mounting frame 1 and substantially orthogonal to the facing side surface (exposed surface) of the facing sheet material H. It can be said that the normal direction R2 of the surface on the facing side is the direction in which the facing sheet material H is pushed further into the facing frame 1 or the direction in which the facing sheet material H is pulled out from the facing frame 1.

<Longitudinal sliding resistance load (adjustment force)>
In the mounting frame 1 and its usage method described so far, the resistance when sliding the mounting sheet material H with the end portions of the mounting sheet material H having a thickness of 1.20 mm along the longitudinal direction L is The load may be 60N (Newton)/100mm or less, and the resistance load when sliding along the longitudinal direction L is related to the ease of position adjustment of the cloth grain M etc. in the facing sheet material H, so the adjustment force It can also be said that.
It can be said that the lower the value of this adjustment force, the more preferable it is, such as the above-mentioned 60N/100mm or less, preferably 43N/100mm or less, and more preferably 40N/100mm or less (32.29N/100mm or 50.12N/100mm). etc.). Up to this point, we have referred to the upper limit of the adjustment force, but it can also be said that the lower limit is 0 N/100 mm or more.

<Resistance load (holding force) of approximately orthogonal direction sliding>
In the mounting frame 1 and its usage method described so far, the mounting sheet material H is held along the direction R substantially perpendicular to the longitudinal direction L while the end portions of the mounting sheet material H having a thickness of 0.15 mm are held. The resistance load when sliding may be 43N (Newton)/100mm or more, and the resistance load when sliding along the substantially perpendicular direction R is such that the mounting frame 1 holds the edge of the mounting sheet material H. It can also be said to be a holding force because it is involved in maintaining the clamped state.
It can be said that the higher the value of this holding force, the better it is, such as the above-mentioned 43N/100mm or more, preferably 70N/100mm or more, and more preferably 90N/100mm or more (45.58N/100mm or 100.28N/100mm). ) etc.). So far, we have referred to the lower limit of the adjustment force, but it can also be said that the upper limit is 400 N/100 mm or less.
In particular, when the holding force is a resistance load when sliding the facing sheet material H from the facing frame 1 in the direction of pulling it out, the higher the holding force is, the greater the tension between at least two facing frames 1. It can be said that it is possible to reduce loosening, sagging, and wrinkles of the installed facing sheet material H, as well as the occurrence of dents when the facing sheet material H is touched after being stretched.

<Test>
In the test of the present invention, Examples and Comparative Examples 1 and 2 were created for the mounting frame 1 described so far, and these Examples and Comparative Examples 1 and 2 were tested against two types of mounting sheet materials H. Examine "adjustment power" and "holding power".
First, Examples and Comparative Examples 1 and 2 will be explained in detail.

<Example>
The configuration of the mounting frame 1 of the example is the same as the first embodiment shown in FIG. The length from end to tip is 2.2 mm.

<Comparative example 1>
The configuration of Comparative Example 1 includes a substrate that is fixed in contact with the base surface S, one support plate that stands up from this substrate, and one side that is formed on the side surface of the one support plate that extends from the middle part in the rising direction to the tip part. The substantially serrated uneven portion, the other support plate that rises from the substrate described above, is bent into a substantially L-shape at a midway point in the rising direction, and rises again from the tip of the substantially L-shaped portion, and this other support plate rises again. The other substantially saw-toothed uneven portion is formed on the side surface of the portion.
The rising height in the configuration of Comparative Example 1 is 22.5 mm, and since there are no multiple tongue pieces, there is no distance D between the front and back surfaces, and the distance from the troughs to the crests of the approximately serrated concavo-convex portions on one side and the other side is 22.5 mm. The height is 1.0 mm.

<Comparative example 2>
The configuration of Comparative Example 2 includes a substrate that is fixed in contact with the base surface S, a support plate that rises from this substrate and is bent at approximately 45 degrees in the middle in the rising direction, and a support plate that extends from the tip of this support plate toward the substrate (downward). It has an edge plate that can hold the end of the facing sheet material between one tongue piece that protrudes from the base plate and the side surface of the one tongue piece that stands up from the above-mentioned substrate.
The rising height in the configuration of Comparative Example 2 is 26.0 mm, and since there is only one tongue, there is no distance D between the front and back, and the distance from the base end to the tip of the tongue that protrudes downward. The length is 4.0 mm.

In the test, for the above-mentioned Examples and Comparative Examples 1 and 2, the "adjustment force" and "holding force" for the two types of facing sheet materials H were slid as shown in FIGS. 6(a) and (b). The results of measuring the resistance load are shown in Table 1 and Figure 7 below.
Here, the length in the longitudinal direction of each of Example and Comparative Examples 1 and 2 is 100 mm in the measurement of "adjustment force" shown in FIG. In the measurement of "holding force", the value was 50 mm, so the value obtained by doubling the measured value in FIG. 6(b) is shown in Table 1 and FIG. 7 as the "holding force". The measured value in this test may be the average value of the values measured for a plurality of (for example, three, etc.) test pieces in each of Examples and Comparative Examples 1 and 2.
Note that the base surface S for Examples and Comparative Examples 1 and 2 is a substantially flat surface.
In addition, the two types of facing sheet material H are facing sheet material H-1 (thickness 1.20 mm, basis weight 379 g/m ² , manufactured by Kawashima Textile Cercon Co., Ltd., 2021 product number: FT6537), facing sheet material H- 2 (thickness 0.15 mm, basis weight 120 g/m ² , manufactured by Kawashima Textile Cercon Co., Ltd., 2021 product number: ME8280).

<Test evaluation>
From Table 1 and FIG. 7, the mounting frame 1 of the example has an "adjusting force" of 60 N for the mounting sheet material H-1 with a thickness of 1.20 mm, regardless of whether it is in the temporary fixing process P1 or the main fixing process P2. /100mm or less, such as "32.29N/100mm" or "50.12N/100mm," making it easier to adjust the position of the facing sheet material, and making it easier to adjust the position of the facing sheet material H-2 with a thickness of 0.15mm. Regardless of whether the "holding force" is in the temporary fixing process P1 or the main fixing process P2, "45.12N/100mm" or "100.28N/100mm", which is 43N/100mm or more, is required for "clamping the facing sheet material". You can also improve your strength.
On the other hand, the configuration of Comparative Example 1 does not have a plurality of tongue pieces, so there is no distance D between the front cover and the back side, and the cover is sandwiched between the approximately serrated concave and convex portions on one side and the other, so that the front cover has a thickness of 1.20 mm. Since the "adjustment force" for the sheet material H-1 is "67.34N/100mm", which exceeds 60N/100mm, it is extremely difficult to adjust the position of the facing sheet material H-1, and it is difficult to adjust the position of the facing sheet material H-1. Since the "holding force" for the sheet material H-2 is "41.82 N/100 mm", which is less than 43 N/100 mm, the facing sheet material H-2 etc. stretched between at least two Comparative Example 1 may loosen, It can be said that the occurrence of loosening, wrinkles, dents, etc. cannot be reduced.
In addition, in the configuration of Comparative Example 2, since there is only one tongue piece, there is no distance D between the front and back surfaces, and the "holding force" for the facing sheet material H-2 with a thickness of 0.15 mm is 43N. /100mm, which is only "20.88N/100mm", and it can be said that the occurrence of loosening, loosening, wrinkles, and dents in the facing sheet material H-2, etc. stretched between at least two Comparative Example 1 cannot be reduced.
In addition, in the example, there are "adjustment force" and "holding force" in the case of the temporary fixing process P1, and "adjusting force" and "holding force" in the case of the main fixing process P2. In this case, only the "adjusting force" for the 1.20 mm thick facing sheet material H-1 may be 60 N/100 mm or less, and for the 0.15 mm thick facing sheet material H-2 in the case of the main fixing process P2. It can also be said that only the "holding force" for the material may be 43 N/100 mm or more.
In addition, regardless of the specific values of "adjustment force" and "holding force", the temporary fixation process P1 and the main fixation process P2 described above are provided (in other words, the plurality of tongue pieces 4 etc. are It can also be said that ``facilitating the position adjustment of the facing sheet material'' and ``improving the clamping force of the facing sheet material'' can be achieved by using only the tongue pieces 4a and 4b on the back side.
