Description

  The present invention relates to a surface treatment technique for a cloth base, and more particularly, to a technique for fixing putty on a resin molded body used for making a cloth base.

As this type of background art, for example, a corner material for a cross base shown in the following patent document made by the present applicant is known.
According to the publication, a molding material made of reinforced foam resin (hereinafter referred to as a corner material) is incorporated in the corner of the wall surface corner, and the corner corner of the wall surface corner is used to achieve an accurate cornering of the wall surface corner. ing.

  Specifically, as shown in FIG. 9, the corner material 100 is assigned to the reference pillar material (interior base structure U), and the end portions of the plaster boards 103 and 104 are respectively attached to the side end surfaces 101 and 102 of the corner material 100. Attach and fix the plasterboard. Further, the thickness of the corner material 100 is equal to that of the gypsum board. By fixing the gypsum board and the corner material in this way, a flat cloth base surface is formed from the corner material 100 to the gypsum boards 103 and 104. Further, the corner portion 105 at the corner of the wall surface is formed by the corner portion 100a of the corner material.

Also, prior to the application of the cloth 108, a so-called putty process is performed in which putty is applied to the joints 107 of the gypsum boards 103 and 104 and the corner material 100 and the periphery thereof to smooth the cloth base surface.
Further, after the putty treatment, the cloth is pasted on the cloth base surface using an adhesive.

JP 2003-176612 A

  By the way, as one of the application operations related to this putty treatment, an operation of thinning and spreading the gypsum putty on the surface of the corner material 100 is performed. However, the putty is difficult to be fixed on the resin corner material and may be peeled off after drying. In particular, in the construction of a wall corner where the coated surface of the putty and the cut portion of the cloth overlap, the strength of the cloth is combined, and the cloth peels off or floats with the putty.

  Further, regarding this point, conventionally, pretreatment such as applying a primer, roughening the surface, or punching the corner material vertically is performed. However, since the primer treatment is intended for a resin, it must be relied on an aqueous primer that is inferior in workability and adhesion. Also, in rough surface processing, the adhesion to the surface of the putty itself is very weak, so a significant improvement in fixability could not be expected.

  On the other hand, in the punching process, since the putty is brought into direct contact with the base material (wood or gypsum board) through a relatively large through hole, a good fixing property can be obtained. However, unevenness due to punching traces tends to remain on the putty-treated surface, and skill and effort are required to obtain a smooth putty-treated surface.

  The present invention has been made to solve such a technical problem, and provides a surface treatment method for a cloth base for fixing putty to a resin molded body used for the cloth base, and the surface treatment is performed. It is an object to provide a craft member for cross base.

In order to solve the above technical problem, the present invention provides:
A surface treatment method for a cloth substrate,
A resin molded body having a surface skin and an internal foam layer having a higher expansion ratio than the surface skin is attached to the interior base to form a cross base surface, and the internal foam layer penetrates the surface skin of the resin molded body. Forming a hole in the surface of the resin molded body,
Furthermore, a surface treatment method for a cloth substrate, wherein a putty is applied to the surface of the resin molded body including the perforations.

  According to this method, when a resin molded body is used as a fabric material for a cloth base, a hole that penetrates the surface skin of the resin molded body and reaches the internal foam layer is formed on the surface of the resin molded body. A putty is applied to the periphery including the perforations to fix the putty on the resin molding.

In other words, the surface skin having poor adhesion of the putty is locally broken by the formation of the perforations, and the putty is engulfed into the internal foam layer through the perforations. Further, the putty that has digged in stays inside the perforation and hardens, and thereafter gets caught by the internal foam layer. Therefore, the putty and the resin molded body are firmly fixed by this catch.
As described above, in the present invention, the fixability of the putty is enhanced by paying attention to the characteristic property of the putty that maintains a predetermined shape after curing without depending on the adhesive force of the putty.

  Further, since the putty is fixed so as to be caught by the internal foam layer as described above, it is not necessary to roughen the surface of the resin molded body. Further, unlike the punching process that penetrates the resin molded body up and down, the formation of the perforations according to the present invention only requires local processing from the surface of the resin molded body to the internal foamed layer. Surface accuracy is maintained. That is, the putty fixability can be improved with the minimum necessary processing without roughening the surface of the resin molding.

  In the present invention, the perforations may be previously formed in the resin molded body.

  That is, by forming perforations in the resin molded body in advance, it is possible to simplify the work at the construction site and shorten the construction period. Further, if the perforations are formed in the manufacturing process of the resin molded body, the perforations can be accurately formed in the resin molded body.

  In the present invention, the perforations may be formed by press punching after the resin molded body is cured.

  According to this method, the perforation is formed by press punching as an additional work after curing. That is, the surface skin and the internal foamed layer are locally compressed by applying a punching process after curing and molding, and it is broken as if it has been shredded toward the inside of the hole. A hole cross-sectional shape having a strong drag in the peeling direction is obtained. The press punching process is a process of making a hole with local pressure.

  Further, when applying the putty, it is preferable to use a putty made of gypsum as a base material.

  A putty based on gypsum can obtain needle-like crystals derived from gypsum after drying and curing. For this reason, countless acicular crystals stick into the inner foam layer, and the fixability of the putty is further improved.

  Moreover, you may provide the said resin molding in the wall surface protruding corner of a cloth | foundation.

  According to this method, the resin molded body according to the present invention is applied in the construction of a wall surface corner that easily overlaps the cut portion of the cloth. That is, by applying the resin molded body having perforations to the construction of the wall surface corner, it is possible to positively prevent the peeling and unevenness of the cloth in the cut portion.

In order to solve the above-described problems, the present invention
It is a cross base construction material used for cross base construction,
A resin molded body made of foamed resin having a surface skin and an internal foamed layer having a higher foaming rate than the surface skin;
Perforating the putty applied to the surface of the resin molded body to reach the internal foam layer of the resin molded body,
The perforations are formed on the surface of the resin molded body and penetrate through the surface skin of the resin molded body to reach the internal foam layer.

According to the present invention configured as described above, the surface skin having poor adhesion of the putty is locally broken by the formation of the perforations, and the putty is taken into the internal foam layer through the perforations. Further, the putty that has digged in stays inside the perforation and hardens, and thereafter gets caught by the internal foam layer. Therefore, the putty and the resin molded body are firmly fixed by this catch.
In other words, according to the cross base construction member of the present invention, the fixability of the putty is enhanced by paying attention to the characteristic of the putty that maintains a predetermined shape after curing without depending on the adhesive force of the putty.

  Further, a plurality of grooves may be formed on the surface of the resin molded body, and each groove may be integrally formed when the surface skin is molded.

In this configuration, a plurality of grooves are formed on the surface of the resin molded body to prevent unevenness of the cloth due to excessive putty. That is, the application amount is optimized by allowing the putty that has been applied excessively to escape into the groove.
Further, since each groove is formed integrally with the surface skin without reaching the internal foam layer, the surface rigidity and surface flatness of the surface skin are maintained.

  Further, the perforations may be formed by press punching after the resin molded body is cured.

  According to this configuration, since the press-piercing process is performed after the resin molded body is cured and molded, the surface skin and the internal foam layer are locally compressed to form a rough fracture surface, and the rough fracture surface causes the putty to peel off. A hole cross-sectional shape having a strong drag in the direction is obtained.

  In the present invention, the surface skin is an infinitely low-foamed or non-foamed film formed on the surface of the molded product during molding of the resin molded body (for example, during extrusion molding). The internal foam layer is a so-called foam cell, core layer, or the like composed of closed cells or open cells formed inside the resin molded body.

  As mentioned above, according to this invention, a putty can be fixed to the resin molding used for a cloth | foundation.

  Hereinafter, a surface treatment method for a cloth substrate according to the present invention and a cloth material for a cloth substrate on which the surface treatment has been performed will be described with reference to an example of the structure of a wall surface of the cloth substrate.

  In interior wall construction of houses, etc., as described above, a plurality of gypsum boards are attached to the interior base structure to form the wall surface, and a resin molded body made of foamed resin having corners is incorporated into the corners of the wall corners. The corner of the protruding wall surface is made with a sharp corner of the resin molded body.

  First, a resin molded body (hereinafter, referred to as a corner material 10) that is incorporated in a wall surface corner will be described. Further, in consideration of the present invention and the scope of claims, the corner material corresponds to the cross base construction member according to the present invention.

The corner member 10 is a long member having a length of more than 2 m, and the surface facing the front of the wall corner in the attached state is the outer surface 20. The surface facing the interior base structure (interior base) is the back surface 30.
A corner 21 is formed at the approximate center of the outer surface 20 as shown in FIG. The corner portion 21 is formed at a right angle in order to increase the cornering accuracy of the wall surface corner. Further, two surfaces 22 and 23 having different widths are provided adjacent to each other with the corner portion 21 interposed therebetween, and the outer surface 20 of the corner member 10 is configured by these surfaces 22 and 23 and the corner portion 21.

  On the other hand, the back surface 30 of the corner member 10 is formed one step lower, leaving one side 31 in the width direction as shown in FIGS. 2 and 3 (see reference numeral 32 in FIG. 2). Further, when the corner member 10 is attached, this lower surface (hereinafter referred to as a fixing surface 32) is fixed in contact with the interior base structure. Reference numeral 35 in FIG. 2 denotes a screw mounting hole. Further, by providing the fixing surface 32 formed one step lower in the longitudinal direction of the member, a step surface 33 perpendicular to the fixing surface 32 is formed on one side 31 of the back surface.

  When attention is paid to the dimensions of each part of the back surface, the thickness of the corner member 10 on the fixed surface 32 (reference symbol T1 in FIG. 3) and the width of the stepped surface upper portion 33a located on one side 31 of the back surface (reference symbol W1 in FIG. 3). Are equal to each other, and the dimensions T1 and W1 of the respective parts are determined in accordance with the thickness of the gypsum board used for wall surface construction. Specifically, the dimensions T1 and W1 are determined in accordance with the standard of 12.5 mm thickness or the standard of 9.5 mm thickness which are variously used in residential construction.

  The corner member 10 is formed of a reinforced foamed resin material obtained by blending polystyrene and a butadiene-styrene copolymer. Moreover, since the resin molded body which consists of this kind of foamed resin raw material is manufactured by extrusion molding, the surface part is pressed and solidified at the time of extrusion molding, and forms a high-density non-foamed layer. That is, the surface of the resin molded body is covered with a so-called film-shaped surface skin 11 as shown in FIG. On the other hand, innumerable foams (voids) are formed inside the member as the resin material is foamed, and the internal foam layer 12 is formed inside the resin molded body by these foams.

Further, a plurality of shallow V-shaped grooves 25 and a plurality of perforations 24 are formed on the outer surface 20 of the corner member 10 as shown in FIG.
Of these, the V-shaped groove 25 is formed integrally with the surface skin 11 during extrusion molding. Specifically, before the surface of the resin molded body is cured, it is formed with an accuracy of a depth of 0.3 to 0.4 mm and a pitch of 0.4 to 0.7 mm. That is, the V-shaped groove 25 is formed integrally with the surface skin 11 without reaching the internal foamed layer 12.

On the other hand, unlike the V-shaped groove 25 described above, the perforations 24 are formed by an additional process after the completion of the molding process, that is, a press-piercing process after surface hardening.
Specifically, a sharp tip (convex shape) at a constant interval is formed by pressing against the outer surface 20 of the resin molded body. Each perforation 24 penetrates through the surface skin 11 and reaches the inner foamed layer 12, and the inner wall surface of the hole breaks as if it has been shredded toward the inside of the hole due to the local pressing of the protrusion. It becomes a cross section (see FIG. 6).

  In addition, the press drilling process is performed so as not to change the external dimensions of the resin molded body, and the specific numerical values such as the depth, diameter, pitch (interval) of the perforations 24 and the forming pressure are the characteristics of the material. Further, it is determined based on various preliminary experiments in consideration of the hardness, film thickness, and foaming ratio of the surface skin 11.

Next, the construction of the wall corner using the corner material 10 will be described.
As shown in FIG. 7, the corner member 10 is fixed to a pillar member (interior base structure) 50 serving as a foundation of a wall surface corner using screws 15a. At that time, if the fixed surface 32 and the stepped surface 33 formed on the back surface 30 of the corner member 10 are abutted and fixed to the corner portion 50 a of the column member, the long corner member 10 is bent with respect to the column member 50. Can be installed straight without any problems.

  The gypsum boards 51 and 52 provided on both sides of the corner material 10 are cut in front of the corner material 10 in order to avoid overlapping with the corner material 10. Further, the corner material 10 and the gypsum boards 51 and 52 are assembled to the pillar material 50, and flat cloth base surfaces P1 and P2 are formed from the corner portion 21 of the corner material 10 to the adjacent gypsum boards 51 and 52.

  Here, the relationship between the corner material 10 and the gypsum boards 51 and 52 will be described. The end surface 10a forming the wide surface 22 on the outer surface 20 of the corner material 10, and the gypsum board 51 connected to the end surface 10a. In this relationship, the thickness T2 of the gypsum board 51 and the thickness T1 (see FIG. 3) of the fixed surface 32 of the corner member 10 are equal to each other (T2 = T1). Further, the thickness T3 of the gypsum board 52 attached in contact with the stepped surface upper portion 33a and the width W1 (see FIG. 3) of the stepped surface upper portion 33a are both equal (T3 = W1). Therefore, in a state in which the corner member 10 and the gypsum boards 51 and 52 are attached to the column member 50, the surface from the corner portion (protruding corner) 21 of the corner member 10 to each gypsum board 51 and 52 becomes flat.

  As described above, the corner member 10 shown in this embodiment has the fixing member 32 and the stepped surface 33 formed on the back surface 30 abutted against and fixed to the corners 50a of the pillar member 50, thereby fixing the pillar member 50 and the gypsum board. Consistency on mounting to 51 and 52 is ensured.

Subsequently, putty processing is performed to flatten the joints 13 and 14 between the plaster boards 51 and 52 and the corner material 10.
In this process, a gypsum putty is prepared, and first, the gypsum putty is applied so as to be pushed into the joints 13 and 14. Subsequently, the gypsum putty is thinned around the seams 13 and 14 and the surface is smoothed using a putty spatula.

  At that time, the gypsum putty 60 filled and applied with a putter spatula is pushed into the perforations 24 formed on the outer surface 20 of the corner member 10 as shown in FIG. The pushed gypsum putty 60 bites into the inner foam layer 12 through the perforations 24 and stays in place to dry and harden. Further, the gypsum putty 60 after drying and hardening is caught on the inner foam layer 12 and the edge 24a (edge of the surface skin) of the perforations 24, and the putty is fixed on the outer surface 20 of the corner member 10 by catching these parts.

Further, since the perforations 24 are formed by the press perforating process as described above, the perforations 24 become rough as if they were torn into the inside of the hole, and the rough hole walls cause the putty to peel in the peeling direction. A hole cross-sectional shape having a strong drag can be obtained.
Therefore, the putty cured in the perforations 24 as shown in FIG. 8 is cured in a shape that conforms to the cross-sectional shape of the holes, and thereafter hooks like a wedge in the perforations. In addition, by using gypsum putty, needle-like crystals derived from gypsum penetrate into the pore wall and exhibit resistance, so that the fixing power can be further improved by these synergistic effects.

  Further, since the formation of the perforations 24 can be limited to various portions of the surface as shown in FIG. 5, the accuracy (smoothness) of the surface is maintained even after the perforation processing. Therefore, a good cloth base surface can be obtained with a small amount of putty. Further, there is no need for putty treatment depending on the place, and the trace of the perforation 24 does not rise even if the cloth is pasted as it is.

  Further, since a plurality of shallow V-shaped grooves 25 are formed on the outer surface 20 of the corner member 10 as shown in FIG. 5, when putting the putty, excess putty is pushed out to the V-shaped groove 25. . That is, the amount of putty applied becomes appropriate by the inflow of putty into the V-shaped groove 25, and a smooth putty-treated surface can be easily obtained.

  Further, the boundary of the putty application surface is finished with a paper file, and an adhesive is applied to the cloth base surfaces P1 and P2 formed of the plaster boats 51 and 52 and the corner material 10 thus subjected to the surface treatment, and the cloth 55 is applied. Paste. Therefore, the cloth 55 is affixed to the cloth base surfaces P1 and P2 without being lifted.

  As described above, according to the present embodiment, by applying the corner material 10 according to the present invention to the construction of the wall surface corner, the gypsum putty is prevented from being peeled off, thereby preventing the cloth from peeling off or floating.

  The above-described embodiment is merely an embodiment, and details thereof can be changed.

  For example, regarding the method for forming the perforations 24, in the present embodiment, the resin molded body is integrally formed. However, the perforations may be formed by pressing sharp projections or needle-like members on the construction site.

  In the above-described embodiment, the gypsum putty is used, but not limited to the gypsum putty, a synthetic resin putty material may be used. Further, as the material of the corner material 10, for example, vinyl chloride, polypropylene, polyethylene, EVA, polycarbonate, etc. can be used in addition to the above-mentioned foamed material.

  In addition, the application range of the surface treatment method of the cloth foundation and the cloth foundation for the cloth foundation according to the present invention is not limited to the construction of the wall surface corners, but is applicable to all places where a foamed resin molded product is used on the cloth foundation surface. it can.
