Description

  The present invention relates to a ground corner material used at a corner or corner where cross grounds such as gypsum board are joined at substantially right angles.

  In interior construction of a building, it is mainstream to construct with wall coverings (cross) such as wallpaper, cloth, synthetic resin cloth and the like. When attaching a wall covering material (cross) of this type, in order to obtain a beautiful finish, it is necessary to finish the base surface to a smooth surface without unevenness. The surface of plasterboard and plywood commonly used is flat, but joints appear at the joints.

  Therefore, the plasterboard and plywood joints are putty-processed to be smoothed. In particular, in the case of the protruding corner which is the corner on the side which protrudes and the corner which is the corner on the side which is recessed, in many cases, it becomes a joint of gypsum board and plywood, and the base finishing is troublesome. For example, in order to flatten the raised and recessed corners of the wall of a building, a thin synthetic resin L-shaped corner material is placed on the protruding and recessed corners to form a corner, and each wall surface is putty with a putty agent etc. Construction is being carried out to smooth the

  As materials of the L-shaped corner material, conventionally, those made of paper, metal, synthetic resin, or a combination of these materials have been commercialized.

  For example, a flat plate portion having a pair of rigidity in order to clearly reveal the corner portion of the corner portion where the two wall surfaces of the structural material of the building intersect to form the corner portion by the corner member having the projecting portion; A hinge that allows the pair of flat plates to be connected in a bendable manner such that the pair of flat plates is at an angle between the two wall surfaces, and the hinge protrudes to at least one side with respect to the thickness direction of the flat A corner material integrally provided with a protruding portion is proposed (for example, see Patent Document 1).

  As such a corner material, it is applied to a base so as to cover the corner portion, and a putty agent is spread and applied from above the corner material, and after being smoothed, the spread applied putty agent is sufficiently dried; Stick the cross. When the putty agent is spread and applied with a patella or the like, in order to improve the familiarity of the putty agent, the base and the corner material, a large number of through holes are bored in the flat portion of most of the corner material.

  The types of through holes are round, long round, square, oval, etc. Also, at most of the drilling positions, two or more rows in a single flat plate portion are staggered. is there. Further, it is rare that the same through hole is provided in the flat plate portion, and the one having the through hole different for each row of the flat plate portion or the one having the round through hole is the mainstream.

It is explanatory drawing explaining the putty spreading process to the through-hole of a base corner material. BRIEF DESCRIPTION OF THE DRAWINGS It is explanatory drawing which shows the structure of one Example of the base corner material of this invention, a figure is a top view, b figure is explanatory drawing which shows the shape of a through-hole. It is explanatory drawing which shows the structure of another Example of the base corner material of this invention, a figure is a top view, b figure is explanatory drawing which shows the shape of a through-hole. It is an explanatory view showing composition of a comparative example of a ground corner material of the present invention, and a figure is a top view and b figure is an explanatory view showing shape of a penetration hole. It is an explanatory view showing composition of another comparative example of a ground corner material of the present invention, and a figure is a top view and b figure is an explanatory view showing shape of a penetration hole. It is an explanatory view showing composition of another comparative example of a ground corner material of the present invention, and a figure is a top view and b figure is an explanatory view showing shape of a penetration hole.

  In the present invention, it is a base corner material which is an elongated body disposed along a line of intersection of an entering corner portion or an exiting corner portion where two wall surfaces to be cross-tensioned intersect each other, and along the longitudinal direction of the elongated body. And a plurality of through holes passing through the front and back surfaces of the pair of flat plate portions, and all of the plurality of through holes are Since the maximum longitudinal width in the direction along the longitudinal direction of the elongated body is long for the maximum transverse width in the direction orthogonal to the longitudinal direction, it is attached to the base and putty applied for smoothing. Even if the putty agent is dried, the advantage of reducing the haze is obtained.

  Specifically, when the base corner material is installed, the putty agent may be thinly applied to the corner portion to be installed, or the corner material may be attached to the corner portion with double-sided tape, and then the putty agent may be used as the base corner. The paint is applied from the top of the material, and both are smoothed with patella or the like so as to eliminate the difference in level between the base corner material and the corner portion. At this time, since the step between the base corner material and the corner portion extends in the longitudinal direction of the corner material, the worker spreads the putty agent with a patella or the like along the longitudinal direction of the base corner material.

  At this time, a clear difference occurs depending on the type of the through hole of the base corner material for the base that has been smoothed in the same manner by a patella or the like, and the long width is longer than the maximum width in the direction orthogonal to the longitudinal direction. In the through-hole which is a long hole in which the maximum longitudinal width in the direction along the longitudinal direction of the body is long, it has been verified that the putty agent has less haze, and the present invention has been made.

  In the through holes of the long holes formed by the pair of flat plate portions of the base corner material of the present invention, preferably, the ratio of the maximum longitudinal width to the maximum horizontal width of the long holes is 1.5 or more. Is good. Specific examples of the long holes include long holes, long round holes, elliptical holes, diamond holes and the like.

  Although various hypotheses are considered for the mechanism of action of this phenomenon, the following hypotheses seem to be the most powerful. That is, the putty agent to be spread is a mixture of a fine aggregate and a liquid such as water or an adhesive, and is a kind of so-called "slurry fluid", and the action mechanism by the behavior of the slurry fluid is good Give an explanation. That is, when smoothing is performed while spreading the putty agent back and forth along the longitudinal direction of the patella, the quick movement of the patellar solidifies the slurry fluid's putty agent to resist shear stress, and then the patellar Or become fluid after passing by.

  More specifically, a slurry fluid is a suspension of liquid and solid particles, also called a slurry, which, depending on the circumstances, behaves like a solid and behaves like a liquid. More specifically, thixotropy, which is considered to be a type of slurry fluid, is a type of non-Newtonian fluid and exhibits an intermediate substance such as a gel-like plastic solid and a sol. It is considered that the putty agent used for the preparation of the substrate also exhibits similar behavior.

  FIG. 1 is an explanatory view for explaining a putty spreading process to a through hole of a base corner material. As shown in FIG. 1 a, the patella 7 is moved to the through hole 13 while spreading the putty agent 15 on the flat plate portion 12 of the base corner material 11. As shown in FIG. 6 b, when the putty agent is moved by being pushed onto the through hole 13 of the flat plate portion 12 and the putty agent is moved, the putty agent 15 pushed by the putty barber escapes into the through hole 13. In this case, since the through holes 13 are pushed in all directions, if the through holes 13 are wide, they spread over the entire wide width and go beyond the tip of the patella 14 and in the direction opposite to the spreading direction. It is thought that there is almost no escape of the putty agent.

  As shown in Fig. c, when the width of the through hole 13 is narrow and it is long in the spreading direction of the patella 10, the putty agent escapes in the direction opposite to the spreading direction beyond the tip of the patella 14; It is considered that the flow lifts the surface of the through hole portion once smoothed, resulting in a swelling phenomenon.

  As shown in FIG. d, just before the patella 14 is removed from the through hole 13, the escape of the putty agent 15 in the direction of the bottom of the through hole 13 disappears, so the surface once swelled remains as it is and dry the putty agent. Along with this, even if the water is evaporated, it is thought that as a result it is difficult to generate haze, and furthermore, it may be in a state of swelling.

  In the present invention, all of the large number of through holes passing through the front and back surfaces in the pair of flat plate portions have a long maximum longitudinal width along the longitudinal direction of the elongated body with respect to the maximum lateral width orthogonal to the longitudinal direction. Since it is a hole, even if the putty agent is dried after being attached to the base, putty-coated and smoothed, an advantage of reducing the haze is obtained.

  The base corner material of the present invention may be a long body disposed along the line of intersection of the in-corner portion or the out-corner portion where the two wall surfaces to be crossed cross each other, and made of paper, metal, synthetic resin Or what is necessary is just to be comprised with the raw material made into the composite body combining these materials. For example, an L-shaped corner material made of metal or plastic and not flexible, or a flexible tape material made of a synthetic resin is provided with a bent portion at the center in the longitudinal direction. What is also called corner tape material to be formed may be used. In particular, if it is a material having flexibility, it is possible to configure the bent portion and the pair of flat portions with the same flexibility, or to have a stiffness that allows the pair of flat portions to be able to hold a flat shape. In addition, a corner tape material which is made of a material having flexibility at the bent portion and the vicinity thereof is highly versatile.

  Examples of the synthetic resin material constituting the bent portion and the pair of flat plate portions include synthetic resins such as polyvinyl chloride, PET resin, HIPS resin, ABS resin, elastomeric resin rubber, or a composite of these. Further, with regard to flexibility, the pair of flat plate portions can be wound in a roll shape in a state flat with respect to the bent portion, and the pair of flat portions can be bent when no force is applied to the elongated body. There should be a degree of flexibility having a restoring property to keep the cross-sectional shape substantially orthogonal to each other. For this purpose, a certain degree of thickness is required. Specifically, the flat plate portion has a thickness of 0.3 to 1.0 mm, preferably 0.4 to 0.6 mm, and the bent portion is thinner than the flat portion, Specifically, the thickness is 0.2 to 0.7 mm, preferably 0.25 to 0.5 mm.

  For example, while extruding a synthetic resin material with an extruder, a long body may be obtained by forming a pair of flat plate portions with respect to a bent portion at the central portion in an L shape. In this case, the obtained elongated body can be wound in a roll while the pair of flat plate portions is flat with respect to the bent portion, and the pair of flat plate portions when no force is applied to the elongated body. May be configured to have resiliency in which cross-sectional shapes substantially orthogonal to each other with the bent portions interposed therebetween.

  The angle between a pair of flat plate portions of the base corner material of the present invention is substantially orthogonal, more specifically, 84 ° or more and 90 ° or less, and more preferably 86 ° or more and 90 ° or less. If it exceeds 90 °, it tends to bend or float up when attaching the flat plate to one side of the corner when it is placed at the corner of the out corner, and similarly when it is placed at the corner of the inside corner when it falls below 84 °. It is because it becomes easy to curve when sticking a flat part on one side of a corner.

And a plurality of through holes 34 formed in three rows penetrating the front and back surfaces in the pair of flat plate portions 33. All of the large number of through holes 34 are diamond holes 34 in which the maximum longitudinal width in the direction along the longitudinal direction of the elongated body is longer than the maximum lateral width in the direction orthogonal to the longitudinal direction. More specifically, it was a diamond having a maximum lateral width of 2.66 mm and a maximum longitudinal width of 9.14 mm.

  The base corner material 40 of the comparative example shown in FIG. 4 includes a bent portion 42 along the central portion along the longitudinal direction of the elongated body 41 and a pair of formed on both sides of the central portion of the elongated body 41. A flat plate portion 43 and a large number of through holes 44 formed in a pair of flat plate portions 43 extending in three rows penetrating the front and back surfaces are provided.

More specifically, it was a diamond with a length orthogonal to the longitudinal direction and a length along the length of 4.79 mm.

  The base corner material 50 of the comparative example shown in FIG. 5 includes a bent portion 52 along the central portion along the longitudinal direction of the elongated body 51 and a pair of the corner portions formed on both sides of the central portion of the elongated body 51. A flat plate portion 53 and a plurality of through holes 54 formed in a pair of flat plate portions 53 extending in three rows penetrating the front and back surfaces are provided. All of the many through holes 54 are round holes 54. More specifically, it has a round shape with a diameter of 4 mm.

  The base corner material 60 of the comparative example shown in FIG. 6 includes a bent portion 62 along the central portion along the longitudinal direction of the elongated body 61 and a pair of formed on both sides of the central portion of the elongated body 61. A flat plate portion 63 and a large number of through holes 64 formed in a pair of flat plate portions 63 extending in three rows penetrating the front and back surfaces are provided. All of the large number of through holes 64 are laterally long elongated round holes 64 whose length in the direction along the longitudinal direction of the elongated body is short with respect to the length in the direction orthogonal to the longitudinal direction. More specifically, a capsule obtained by rotating the elongated round hole 24 shown in FIG. 2 by 90 degrees and having a length of 5.32 mm orthogonal to the longitudinal direction and a length of 2.66 mm along the longitudinal direction It was shaped.

  The base corner material shown in FIGS. 2 to 6 was used to perform base layer adjustment to verify the haze of the through hole portion. Specifically, after attaching each base corner material to a test piece on a square pillar material imitating an output corner with a double-sided tape, using the same putty agent, with the same operation procedure and operation speed, with patellar The spreading application operation of the putty agent was performed. The same operation was performed on each of the ground corner materials with three test pieces each.

  On the next day after the spreading coating operation was performed, the haze of the through hole portion of the substrate adjustment was verified. The verification was performed by a person different from the one in which the ground adjustment was performed, and specifically, which ground corner material was used was laid down. The results are shown in Table 1. The amount of haze in the table shows the average value of each individual, and is negative when it is rougher than the putty-coated surface, and positive when it is swollen, and the larger the value, the better the value.

  As shown in Table 1, as the hole shape is longer in the longitudinal direction of the base corner material, a better result is obtained with less haze. On the other hand, it has been shown that when the hole is elongated in the width direction, the result is rather worse than that of a round hole or a diamond having the same vertical and horizontal dimensions. In addition, since it is sufficient to remove the putty agent coming out of the surface when the amount of the haze is positive, it can be processed in a short time as compared with the trouble of applying the putty agent.

  Also, regarding the anchor effect, there is no clear difference in the shape of the hole, and it depends on the area and pitch of the hole (the area of the hole is larger and the finer the pitch is, the stronger the hole). If the area is replaced with the same shape as the hole shape of the invention, it is possible to improve the generation of a little jade while maintaining the anchor effect.
