Description

[Technical Field]

[0001] The present invention relates to a wall material auxiliary member used in a wall connecting hole provided in a wall material, a wall structure, and a wall material installation method. [Background technology]

[0002] Conventionally, when constructing wall materials at high altitudes, the first step is to drill holes in the wall materials or substrate, install wall ties in the holes, and then assemble scaffolding through the wall ties. After the scaffolding work is completed, the scaffolding and wall ties are removed and the holes are filled.

[0003] A method for filling holes for wall joints is disclosed, for example, in Patent Document 1. The method in Patent Document 1 involves filling the holes with a sealant or the like and then attaching a sticker on top of it.

[0004] Patent Document 2 also discloses an auxiliary member for a hole used to connect walls. The auxiliary member in Patent Document 2 involves attaching a fastening nail member to a base (pillar), and then attaching the wall material so that the tip of the fastening nail member protrudes from the hole in the wall material. After that, a filler is filled into the gap between the fastening nail member and the hole in the wall material, and an insert (decorative cap) is attached to the fastening nail member. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent Publication No. 2019-218704 [Patent Document 2] Patent Publication No. 9-256629 Summary of the Invention [Problem to be solved by the invention]

[0006] However, when using the method of Patent Document 1, if you want to reuse the portion of the wall where a filler such as a sealant has been filled in the hole during renovation, etc., as a wall joint, you need to remove the filler. Removing the filler that has filled the hole takes time and effort, and it is difficult to remove the filler that also functions as an adhesive, and there is a risk that the wall material around the hole will be damaged during removal, which will spoil the aesthetic appearance.

[0007] The auxiliary member in Patent Document 2 fills the filler from the surface side of the wall material, so it cannot fully fill the holes on the back side of the wall material. As a result, gaps are created between the wall material and the filler. Furthermore, while the surface side of the wall material is waterproofed by the presence of an insert around the holes, the back side has no insert around the holes. As a result, water is more likely to enter the holes on the back side of the wall material than on the front side. In the part of the wall material where the holes are formed, the base material of the wall material is exposed to the outside, which makes it more likely to absorb water than the surface or back side of the wall material, potentially leading to deterioration of the wall material through this part.

[0008] The present application has been made in consideration of such circumstances, and is intended to prevent water from entering holes in wall materials not only from the front side but also from the back side, and to make it easy to reconnect walls when renovating, etc. [Means for solving the problem]

[0009] The wall material auxiliary member of the first aspect of the present invention is an auxiliary member for wall material used in a hole formed in a wall material, and the wall material auxiliary member includes a receiving member inserted from one side of the wall material in which a hole has been formed in advance, and an insert member inserted into the receiving member from the other side of the wall material, and the receiving member is inserted into the inner wall surface of the hole. A little At least some of them are in contact and has a through hole that penetrates from one end to the other end. From the cylindrical part and the end of the cylindrical part Without blocking the through-hole The cylindrical part outside Extends radially and abuts against one side of the wall material possible a flange portion, and the insert is inserted into the cylindrical portion; penetration The detachable insertion part is attached to the inner wall surface of the hole, and extends from the end of the insertion part in the radial direction of the insertion part. penetration and a cover portion that is larger than the hole.

[0010] The first aspect of the auxiliary member for wall materials of the present invention is used for wall materials having holes formed therein, and by the flange portion of the receiving member abutting against one side of the wall material, it is possible to prevent water from entering the hole in the wall material where the base material is exposed from one side.

[0011] In addition, the inserting portion of the insert member is detachable from the inner wall surface of the hole in the cylindrical portion of the receiving member, which makes it easy to re-install the wall joint when remodeling or other such work.

[0012] In a second aspect of the present invention, it is desirable that the auxiliary member for wall materials has a screw thread formed on each of the cylindrical portion and the insertion portion.

[0013] In this case, when inserting the insert part of the insert into the cylindrical part of the receiving part, it can be easily inserted by simply turning the insert, for example, clockwise. Also, it is possible to insert along each other's threads, and this specification makes it easy for the insert to enter the receiving part and difficult to come off.

[0014] In a third aspect of the present invention, the auxiliary member for wall materials has an insertion portion formed with a reduced portion in which the diameter of the insertion portion decreases from one end side where the covering portion is located to the end side opposite the covering portion, and it is desirable that no threads are formed in the reduced portion.

[0015] In this case, when inserting the insertion part into the cylindrical part, if the entire insertion part has a screw thread, the insertion cannot be easily performed, but since there is a reduced part without a screw thread, the reduced part can be easily inserted and temporary alignment can be performed, which makes the subsequent insertion work easier.

[0016] The fourth aspect of the present invention is a wall structure for a building, in which a wall material auxiliary member is inserted into a hole formed in advance in a wall material, and the wall material auxiliary member includes a support member inserted into the hole from one side of the wall material, and an insert member inserted into the support member from the other side of the wall material, and the support member is inserted into the inner wall surface of the hole. A little At least some of them are in contact and has a through hole that penetrates from one end to the other end. From the cylindrical part and the end of the cylindrical part Without blocking the through-hole The cylindrical part outside Extends radially and abuts against one side of the wall material possible and a flange portion, and the insert member is penetration The insertion portion is detachable from the inner wall surface of the hole and abuts against the cylindrical portion. The insertion portion extends from the end of the insertion portion in the radial direction of the insertion portion and has a diameter of penetration It has a cover that is larger than the hole.

[0017] The wall structure of a building according to the fourth aspect of the present invention provides the same effects as those provided by the auxiliary member for a wall material according to the first aspect.

[0018] In a fifth aspect of the present invention, the wall structure preferably includes a first seal attached to cover the flange portion and one side of the wall material around the flange portion, and a second seal attached to cover the cover portion and the other side of the wall material around the cover portion.

[0019] In this case, by attaching the first seal to the flange and one side of the wall material around the flange, a larger area on that side of the wall material can be waterproofed. Also, by closely contacting the flange and one side of the wall material, it becomes more difficult for water to get into holes formed in the wall material. By attaching the second seal to the cover and the other side of the wall material around the cover, the holes formed in the wall material and the cover are less noticeable.

[0020] A sixth aspect of the present invention is a method for installing wall materials, which uses a support member for wall materials in a hole formed in the wall material, and the support member has a tubular portion that at least a part of which abuts against the inner wall surface of the hole, and a flange portion that extends radially from the end of the tubular portion and abuts against one side of the wall material, and the method comprises the following steps: a first step of inserting the support member into a pre-formed hole in the wall material from one side of the wall material and abutting the flange against the one side of the wall material; a second step of installing the wall material; a third step of fixing anchors directly or indirectly to a base; and a fourth step of connecting wall ties to the anchors and then connecting scaffolding to the wall ties.

[0021] According to the sixth aspect of the wall material installation method of the present invention, the flange portion of the receiving material abuts against one side of the wall material, so that the scaffolding can be installed while preventing water from entering the hole in the wall material where the base material is exposed on one side.

[0022] In a seventh aspect of the present invention, a method for constructing wall materials is a method for constructing wall materials using an insert member of an auxiliary member for wall materials, wherein the insert member inserted into the receiving member from the other side of the wall material is detachable from the tubular portion, and comprises an insert portion that abuts the tubular portion, and a cover portion that extends radially from the end of the insert member and has a diameter larger than or equal to the tubular portion, and the method comprises a fifth step of removing the scaffolding, wall tie, and anchor in that order, and a sixth step of inserting the insert member into the tubular portion.

[0023] In this case, the insertion portion of the insert material is removably inserted into the tubular portion of the receiving material, so that when reconnecting walls during renovations, etc., the material can be reused simply by removing the insertion portion without drilling new holes, which is very convenient. [Effects of the Invention]

[0024] This allows easy re-construction of wall joints during renovations, etc., and also prevents water from entering holes in the wall material not only from the front side but also from the back side. [Brief explanation of the drawings]

[0026] A first embodiment of the present invention will be described below. Fig. 1 shows a wall structure of a wall material using an auxiliary member for wall materials (hereinafter referred to as auxiliary member 1). An exterior wall material 3, which is an example of a wall material, has a hole 60 for connecting walls, and auxiliary member 1 is inserted into this hole 60. Note that the wall material is not limited to an exterior wall material, and may be, for example, a decorative board for exteriorizing a building, an indoor structural panel, an interior board, or the like. On one side of the wall material, that is, the back surface 3B of the exterior building material 3, a first seal 30 is affixed to the auxiliary member 1 and the back surface 3B around the auxiliary member 1. On the other side of the wall material, that is, the front surface 3A of the exterior building material 3, a second seal 40 is affixed to the auxiliary member 1 and the front surface 3A around the auxiliary member 1.

[0027] Next, we will explain the auxiliary member 1. As shown in Figure 2, the auxiliary member 1 includes a receiving member 7 and an insert member 20. The receiving member 7 is a cylindrical member that is inserted into the insert member 20. The insert member 20 is a member that is inserted into the receiving member 7, and is detachable from the receiving member 7.

[0028] As shown in FIG. 3 , the insert member 20 includes an insertion portion 22 and a cover portion 21 extending radially from an end of the insertion portion 22. In this embodiment, the diameter of the cover portion 21 decreases from one end of the cover portion 21 opposite the insertion portion 22 to the other end of the cover portion 21 that connects to the end of the insertion portion 22. That is, in this embodiment, the cross section of the cover portion 21 in a front view is a substantially isosceles trapezoid. The cross section of the cover portion 21 in a front view is not limited to a substantially isosceles trapezoid, and may be, for example, a rectangle in which the diameter of one end is the same as the diameter of the other end.

[0029] The insertion portion 22 has a portion where a screw thread 24 is formed. In the insertion portion 22, on the tip side of the screw thread 24, i.e., on the end opposite the cover portion 21, a reduced portion 25 is formed where the diameter of the insertion portion 22 becomes smaller toward the tip. Note that the screw thread 24 is not formed in the reduced portion 25. The diameter of the insertion portion 22 is a size that allows it to threadably engage with the screw thread 13 on the inner wall surface of the tubular portion 12, which will be described later. The diameter of the insertion portion 22 is, for example, about 14 mm to about 20 mm, and is 17.0 mm in this embodiment. The size of the insertion portion 22 is, for example, about 12 mm to about 23 mm, and is 14.0 mm in this embodiment.

[0030] As shown in FIG. 4 , the cover portion 21 has a linear (minus sign-shaped) groove 23 formed in the center, which is recessed toward the insertion portion 22. When connecting the insertion portion 22 to the tubular portion 12 (described later), a screwdriver or the like is inserted into the groove 23 and turned, causing the insert 20 to move inward into the tubular portion 12. The groove 23 is not limited to a linear groove as in this embodiment, but may be, for example, a cross-shaped (plus sign-shaped), square-shaped, or hexagonal-shaped groove. Furthermore, the groove 23 is not limited to the central portion of the cover portion 21 as in this embodiment, but may extend linearly from one end of the cover portion 21 to the other end, for example. Furthermore, although the cover portion 21 is round in this embodiment, it is not limited thereto, and may be, for example, a square or other angular shape.

[0031] As shown in FIG. 5 , the receiving member 7 includes a cylindrical portion 12 and a flange portion 11 extending radially from the end of the cylindrical portion 12. A hole 14 is formed in the cylindrical portion 12. The flange portion 11 is cross-shaped. In this embodiment, the length of the flange portion 11 extending from the end of the cylindrical portion 12 is such that the diameter of the circular portion surrounding the hole 14 is 5.0 mm and the distance to the tip of the cross-shaped portion is 13.0 mm. The flange portion 11 must be long enough to protect the periphery of the hole 14, and the diameter of the circular portion surrounding the hole 14 is preferably approximately 3.0 mm or more. Furthermore, as long as the diameter of the circular portion surrounding the hole 14 is approximately 3.0 mm or more, the flange portion 11 may be square-shaped or star-shaped, and any shape is acceptable.

[0032] 6, threads 13 are formed on the inner wall surface of the cylindrical portion 12 to be threadedly engaged with threads 24 of the insert member 20. The diameter of the cylindrical portion 12 is, for example, about 17 mm to about 23 mm, and is 20.0 mm in this embodiment. The size of the cylindrical portion 12 is, for example, about 12 mm to about 23 mm, and is 14.0 mm in this embodiment.

[0033] As shown in Figure 2, when using the auxiliary member 1 in a hole 60 formed in the exterior wall material 3, the first seal 30 is used. As shown in Figure 7, the first seal 30 is large enough to be attached to cover the flange portion 11, including the area around the flange portion 11. A hole is formed in the first seal 30, and in this embodiment, the hole 14 in the tubular portion 12 and the hole in the first seal 30 are arranged to overlap. Furthermore, the diameter of the hole 14 in the tubular portion 12 and the diameter of the hole in the first seal 30 are approximately the same.

[0034] Next, the base 2 will be described. As shown in FIG. 8, a plate 50 is fixed to the base 2 with fastening members 52 such as screws. The plate 50 has a protruding portion on the side opposite the base 2. The protruding portion of the plate 50 has holes for connecting components, and threads are formed on the inner wall surface. In this embodiment, the base can be selected from a wood base, a steel frame base, or any other suitable material.

[0035] Next, the exterior wall material 3 will be described. As shown in FIG. 8, the exterior wall material 3 is installed with a gap (air permeable layer) formed between it and the substrate 2, and has a hole 60 formed therein. The thickness of the exterior wall material is, for example, about 14 mm to about 25 mm, and is 16.0 mm in this embodiment. In this embodiment, the thickness of the exterior wall material (16.0 mm) is larger than the size of the insertion portion 22 (14.0 mm) and the size of the tubular portion 12 (14.0 mm). The diameter of the hole 60 is desirably large enough to allow portions of anchors 54 and 55 (described later) to pass through the hole 60, and is, for example, about 17 mm to about 23 mm. In this embodiment, the diameter of the hole 60 is 20.0 mm. In this embodiment, as shown in FIG. 2, the hole 60 abuts against one end of the cover portion 21. The hole 60 in the exterior wall material 3 is arranged in the direction in which the member connection holes in the plate 50 face.

[0036] Next, the construction procedure for the exterior wall material 3 using the auxiliary member 1 will be described. In the wall structure of this embodiment, as shown by arrow A in Fig. 8, the support member 7 and the first seal 30 are arranged from the back surface 3B of the exterior wall material 3 toward the hole 60. As shown by arrow B, the insert member 20 and the second seal are arranged from the front surface 3A of the exterior wall material 3 toward the hole 60. The construction of the exterior wall material 3 of this embodiment comprises steps 1 to 6, which will be described later. As a preliminary step to step 1, as shown in Fig. 8, the plate 50 is first fixed to the base 2 with fastening members 52 such as screws.

[0037] In the first step, the receiving material 7 is inserted into the pre-formed hole 60 in the exterior wall material 3 from the back surface 3B side of the exterior wall material 3, and the back surface 3B is brought into contact with the flange portion 11. When drilling the hole 60 in the exterior wall material 3, the positional relationship is measured in advance so that the hole 60 in the exterior wall material 3 is aligned with the direction in which the component connection hole in the plate 50 will face when the exterior wall material 3 is installed.

[0038] At this time, the tubular portion 12 of the receiving material 7 abuts against the inner wall surface of the hole 60. Note that the tubular portion 12 may abut only a portion of the inner wall surface of the hole 60, rather than the entire surface. Furthermore, the flange portion 11 may be abutted against the back surface 3B of the exterior building material 3 with waterproof double-sided tape attached to the flange portion 11. This configuration strengthens the adhesion between the flange portion 11 and the back surface 3B.

[0039] Alternatively, the first seal 30 with holes drilled in advance may be attached to the receiving material 7 and the back surface 3B of the exterior wall material 3 around the receiving material 7. At this time, the holes in the first seal 30 are positioned at approximately the same position as the tubular portion 12 and overlap with each other.

[0040] In the second step, the exterior building material 3 is installed. At this time, the holes in the plate 50 and the holes 60 in the exterior building material 3 are positioned in a substantially straight line. In addition, an air-permeable layer may be formed between the base 2 and the exterior building material 3 as appropriate.

[0041] In the third step, as shown in Figure 9, the anchor 54 is indirectly fixed to the base 2 via the plate 50. Specifically, with the base 2 and plate 50 already connected, the anchor 54 is inserted into a hole in the plate 50 and connected. The anchor 54 has a hole for connecting a component drilled in the opposite direction to the insertion direction of the anchor into the plate 50, and the hole is threaded. At this time, the tip of the anchor 54 is positioned so as to protrude through the hole 60 beyond the surface 3A of the exterior building material 3. Unlike this embodiment, the tip of the anchor 54 may be positioned closer to the base 2 than the position of the hole 60 or the back surface 3B of the exterior building material 3.

[0042] In the fourth step, the wall ties 8 are connected to the anchors 54, and then the scaffolding 9 is connected to the wall ties 8. Specifically, as shown in FIG. 10 , the wall ties 8 are connected to the holes in the anchors 54. The wall ties 8 have clamps for connecting members in the opposite direction to the direction in which they are inserted into the anchors 54. After the wall ties 8 and anchors 54 are connected, the clamps of the wall ties 8 are connected to the scaffolding 9.

[0043] In the fifth step, the scaffolding 9, the wall ties 8, and the anchors 54 are removed in this order. This step is carried out after the work on the scaffolding has been completed.

[0044] In the sixth step, the inserting portion 22 is inserted into the cylindrical portion 12. Specifically, the inserting portion 22 is inserted into the inner wall surface of the hole 14 of the cylindrical portion 12. At this time, it is desirable that the surface of the covering portion 21 of the inserting member 20 and the surface 3A of the exterior wall material 3 are arranged on the same plane as shown in FIG. 2. When the surface 3A and the covering portion 21 are on the same plane, Therefore, The cover portion 21 is less noticeable. After the sixth step, a second seal 40 may be applied to the cover portion 21 of the insert 20 and the surface 3A around the cover portion 21. The second seal 40 is preferably the same color as the surface 3A to reduce the visibility of the hole 60 and the cover portion 21. In order to keep the cover portion 21 and the surface 3A flush with each other when the plate thickness is large, the threads 24 of the insert 22 may be partially exposed from the tubular portion 12, rather than being completely exposed from the tubular portion 12 as shown in FIG. 2. The threads 24 may also be covered with waterproof sealing tape.

[0045] In the first embodiment, the receiving material 7 is inserted into a hole 60 formed in the exterior building material 3. When the receiving material 7 is inserted into the hole 60, the tubular portion 12 abuts against the inner wall surface of the hole 60, and the back surface 3B of the exterior building material 3 abuts against the flange portion 11. The flange portion 11 abuts against the back surface 3B, thereby preventing water from entering the hole 60 from the back surface 3B side. Furthermore, a first seal with a hole pre-formed in it is affixed to the flange portion 11 and the back surface 3B around the flange portion 11. The presence of the first seal makes it possible to waterproof a larger area of ​​the back surface 3B. Furthermore, the close contact between the flange portion 11 and the back surface 3B makes it even more difficult for water to enter the hole 60.

[0046] The insertion portion 22 of the insert member 20 has a thread 24 and a reduced portion 25 where no thread is formed. The reduced portion 25 makes it easier to fit the reduced portion 25 into the tubular portion 12, facilitating the subsequent insertion operation. The tubular portion 12 also has a thread 13. Therefore, when the thread 24 of the insertion portion 22 is connected to the thread 13, the insert member 20 can easily be screwed deeply into the receiving member 7 by turning the cover portion 21, for example, clockwise. The insertion portion 22 can also be easily removed by turning it, for example, counterclockwise, relative to the inner wall surface of the tubular portion 12. In other words, the insert member 20 is detachable from the receiving member 7.

[0047] The wall structure of this embodiment, which uses the auxiliary member 1 equipped with the insert member 20 and the support member 7, does not require sealing during construction. Therefore, for example, if a wall-connecting hole 60 is covered with sealing and another wall-connecting component is to be installed through the same hole 60 during renovations, the sealing must be removed. However, the sealing is an adhesive, and there is a risk of damaging the surrounding exterior wall material when it is removed. The auxiliary member 1 of this embodiment is convenient because the insert member 20 can be easily removed from the support member 7 without drilling a new wall-connecting hole during renovations, etc. Furthermore, in the case of so-called dry construction, where a ventilation layer is provided between siding or tile materials and the base, the ventilation layer makes sealing difficult. The present invention also solves this problem.

[0048] Additionally, the cover portion 21 of the insertion portion 22 and the surface 3B of the exterior building material 3 around the cover portion 21 are covered with a second seal 40. The second seal 40 makes the hole 60 formed in the exterior building material 3 and the cover portion 21 less noticeable.

[0049] FIG. 11 shows the third step of the second embodiment, in which the anchor 55 is fixed directly to the base 2. The second embodiment is similar to the first embodiment described above, except that the anchor 55 is fixed directly to the base 2 without using the plate 50. The construction procedure of the second embodiment differs from the first to sixth steps of the first embodiment described above only in the third step, with the other steps being common. In the third step of the second embodiment, the anchor 55 is fixed directly to the base 2 without using the plate 50.

[0050] The above-described embodiments are merely examples, and the present invention is not limited to these descriptions. For example, although the auxiliary member 1 in this embodiment is made of resin, it may be made of a material with elasticity and flexibility, such as rubber. When the auxiliary member 1 is made of rubber, neither the tubular portion 12 nor the insertion portion 22 may have threads 13, 24 formed thereon, and the insertion portion 22 may have an elastic protrusion on its outer periphery. This protrusion is preferably large enough to abut and press against the tubular portion 12 when inserting the insertion portion 22 into the tubular portion 12. By having this protrusion, the protrusion of the insertion portion 22 continues to press against the tubular portion 12 even after insertion, so it does not easily come off after installation. Furthermore, the insertion portion 22 is elastic, so it can be easily removed from the tubular portion 12.

[0051] In the first embodiment, the insertion portion 22 is shown to have the threads 24 and the reduced portion 25, but the insertion portion 22 may have the threads 24 formed all over it and not have the reduced portion 25. Also, the insertion portion 22 and the tubular portion 12 may not have the threads 24 formed on each other. In such a case, the insertion portion 22 can be easily inserted into the inner wall surface of the hole 14 of the tubular portion 12 by hand without using any tools. [Explanation of symbols]
