Description
本発明は、躯体および仕上げ材からなる壁体を補修するピンニング工法およびこれに用いられるピンニング工法用アンカーピンに関する。 The present invention relates to a pinning method for repairing a wall body made of a skeleton and a finishing material, and an anchor pin for the pinning method used therefor.
ピンニング工法とは、外壁などの壁体の仕上げモルタル、貼付けモルタルやタイルなどの仕上げ材に浮きが生じた部分の剥落を防止するための工法である。ピンニング工法では、エポキシ樹脂系注入材などの接着剤とアンカーピンとを併用して、躯体と仕上げ材とを一体化する。 The pinning method is a method for preventing peeling of a floating portion of a finishing mortar such as an outer wall, a pasting mortar, or a tile. In the pinning method, an adhesive such as an epoxy resin injection material and an anchor pin are used in combination to integrate the skeleton and the finishing material.
従来、このようなピンニング工法に用いられているアンカーピンは、ピン胴体部から頭部にかけてテーパー状になっているものが多い（例えば、特許文献１参照。）。図１２は従来のピンニング工法に用いられているアンカーピンの側面図である。図１２に示すように、従来のアンカーピン１００は、胴体部１０１と頭部１０２とから形成されている。頭部１０２は、胴体部１０１から頭端部１０３にかけてテーパー状になっている。このアンカーピン１００は、図１３に示すように、貼付けモルタル４Ａやタイル４Ｂなどの仕上げ材を貫通して躯体３に形成された穿孔穴５内に挿入され、接着剤６により一体化される。 Conventionally, many anchor pins used in such a pinning method have a tapered shape from the pin body to the head (see, for example, Patent Document 1). FIG. 12 is a side view of the anchor pin used in the conventional pinning method. As shown in FIG. 12, the conventional anchor pin 100 is formed of a body portion 101 and a head portion 102. The head portion 102 has a tapered shape from the body portion 101 to the head end portion 103. As shown in FIG. 13, the anchor pin 100 is inserted into a perforated hole 5 formed in the skeleton 3 through a finishing material such as a sticking mortar 4A or a tile 4B, and is integrated by an adhesive 6.
図１４に示すように、従来のピンニング工法は、貼付けモルタル４Ａやタイル４Ｂなどの仕上げ材をアンカーピン１００の頭端部１０３で押さえ込んだ構造である。すなわち、この従来のピンニング工法では、穿孔穴５とアンカーピン１００は、頭部１０２の一部分（頭端部１０３）しか接触していない。このアンカーピン１００の頭端部１０３は、前述のようにテーパー状になっており、非常に薄いため、支持強度が見込めず、この部分に力がかかると簡単に変形してしまう。例えば、図１５に示すように、アンカーピン１００により支持しているタイル４Ｂに不意な力が加わった場合、薄い頭端部１０３が変形してしまい、タイル４Ｂが外れてしまうおそれがある。 As shown in FIG. 14, the conventional pinning method has a structure in which a finishing material such as affixed mortar 4A or tile 4B is pressed by the head end portion 103 of the anchor pin 100. That is, in this conventional pinning method, the perforated hole 5 and the anchor pin 100 are in contact with only a part of the head 102 (head end 103). The head end portion 103 of the anchor pin 100 has a tapered shape as described above and is extremely thin, so that support strength cannot be expected and the anchor pin 100 is easily deformed when a force is applied to this portion. For example, as shown in FIG. 15, when an unexpected force is applied to the tile 4B supported by the anchor pin 100, the thin head end portion 103 may be deformed and the tile 4B may come off.
また、従来のピンニング工法では、図１６に示すように穿孔穴５に対してアンカーピン１００が斜めに入ってしまった場合に、アンカーピン１００の頭端部１０３がタイル４Ｂの表面と面一にならず、タイル４Ｂの表面に凹凸ができてしまう。この場合、タイル４Ｂの表面を修正しなければならないため、施工時間がかかってしまうという問題がある。また、この凹凸修正は、作業者のスキルによって外観美を悪くしてしまうという問題がある。 Further, in the conventional pinning method, when the anchor pin 100 is obliquely inserted into the drilled hole 5 as shown in FIG. 16, the head end portion 103 of the anchor pin 100 is flush with the surface of the tile 4B. However, the surface of the tile 4B is uneven. In this case, since the surface of the tile 4B must be modified, there is a problem that the construction time is long. Further, this unevenness correction has a problem that the appearance beauty is deteriorated depending on the skill of the operator.
そこで、本発明においては、穿孔穴に対してアンカーピンが斜めに入った場合であってもアンカーピンの頭部と穿孔穴の開口縁部との接触面積を広く維持して、アンカーピンによる仕上げ材の支持強度を向上させることが可能なピンニング工法およびこれに用いられるピンニング工法用アンカーピンを提供することを目的とする。 Therefore, in the present invention, even when the anchor pin enters the drilled hole at an angle, the contact area between the head of the anchor pin and the opening edge of the drilled hole is maintained wide and finished with the anchor pin. It is an object of the present invention to provide a pinning method capable of improving the supporting strength of a material and an anchor pin for the pinning method used therefor.
本発明のピンニング工法は、躯体および仕上げ材からなる壁体を補修するピンニング工法であって、仕上げ材を貫通して躯体に穿孔穴を形成すること、穿孔穴の開口縁部に球帯状の面取り部を形成すること、穿孔穴に接着剤を注入すること、球帯状の面取り部に面接触する球帯状面を頭部に有するアンカーピンを接着剤が注入された穿孔穴に挿入し、アンカーピンの頭部の球帯状面と穿孔穴の球帯状の面取り部とを面接触させることを含む。 The pinning method of the present invention is a pinning method for repairing a wall body composed of a skeleton and a finishing material, in which a perforated hole is formed in the skeleton through the finishing material, and a spherical band-shaped chamfer is formed at the opening edge of the perforated hole. Forming a part, injecting adhesive into the perforated hole, inserting an anchor pin with a spherical surface in the head that makes surface contact with the chamfered part of the spherical band into the perforated hole into which the adhesive was injected, and anchor pin Includes surface contact between the globular surface of the head and the globular chamfer of the perforated hole.
本発明のピンニング工法によれば、アンカーピンの頭部の球帯状面と穿孔穴の球帯状の面取り部とが面接触するため、穿孔穴に対してアンカーピンが斜めに入った場合であってもアンカーピンの頭部と穿孔穴の開口縁部との接触面積を広く維持することができる。 According to the pinning method of the present invention, the spherical surface of the head of the anchor pin and the chamfered portion of the perforated hole come into surface contact with each other, so that the anchor pin enters the perforated hole at an angle. Also, the contact area between the head of the anchor pin and the opening edge of the perforated hole can be maintained wide.
本発明によれば、アンカーピンの頭部の球帯状面と穿孔穴の球帯状の面取り部とが面接触するため、穿孔穴に対してアンカーピンが斜めに入った場合であってもアンカーピンの頭部と穿孔穴の開口縁部との接触面積を広く維持することができ、アンカーピンによる仕上げ材の支持強度を向上させることが可能となる。 According to the present invention, since the spherical surface of the head of the anchor pin and the chamfered portion of the perforated hole are in surface contact with each other, the anchor pin is formed even when the anchor pin is obliquely inserted into the perforated hole. The contact area between the head and the opening edge of the perforated hole can be maintained wide, and the supporting strength of the finishing material by the anchor pin can be improved.

本発明の実施の形態におけるピンニング工法は、図４に示すように、建物の外壁や内壁などの壁体２において、躯体３から仕上げモルタル（図示せず。）、貼付けモルタル４Ａやタイル４Ｂなどの仕上げ材４に浮きが生じた部分などの要補修箇所に穿孔穴５を形成し、その穿孔穴５内にエポキシ樹脂系注入材などの接着剤６を注入し、アンカーピン１を挿入して、躯体３と仕上げ材４とを一体化することにより補修を行うものである。 In the pinning method according to the embodiment of the present invention, as shown in FIG. 4, in the wall body 2 such as the outer wall and the inner wall of the building, from the skeleton 3 to the finishing mortar (not shown), the pasted mortar 4A, the tile 4B, etc. A perforated hole 5 is formed in a portion requiring repair such as a portion where the finishing material 4 is lifted, an adhesive 6 such as an epoxy resin-based injection material is injected into the perforated hole 5, and an anchor pin 1 is inserted. The repair is performed by integrating the skeleton 3 and the finishing material 4.
図１に示すように、本発明の実施の形態におけるピンニング工法用のアンカーピン１は、棒状（円柱状）の胴体部１０と、球帯状の頭部１１とから形成されている。胴体部１０と頭部１１とは、例えばステンレス鋼等により一体に形成されている。胴体部１０の直径Ｒ１０は、後述する穿孔穴５の内径Ｒ５（図２（Ａ）参照。）よりも小径に形成されている。なお、図示していないが、胴体部１０の外周面には、引き抜き強度を高めるためにローレット加工により凹凸が形成される。 As shown in FIG. 1, the anchor pin 1 for the pinning method according to the embodiment of the present invention is formed of a rod-shaped (cylindrical) body portion 10 and a spherical band-shaped head portion 11. The body portion 10 and the head portion 11 are integrally formed of, for example, stainless steel. The diameter R10 of the body portion 10 is formed to be smaller than the inner diameter R5 (see FIG. 2A) of the drilling hole 5 described later. Although not shown, irregularities are formed on the outer peripheral surface of the body portion 10 by knurling in order to increase the pull-out strength.
頭部１１は、円形状の端面１１Ａと、胴体部１０との接続面１０Ａから端面１１Ａに至る球帯状面１１Ｂとを有する。胴体部１０との接続面１０Ａおよび端面１１Ａは、胴体部１０の軸線１０Ｂに対して直交する平面である。なお、本実施形態においては、頭部１１は、直径Ｒ１１の球体を２つの平行な接続面１０Ａおよび端面１１Ａで切った球台である。球帯状面１１Ｂは、この球台の側面部分である。 The head portion 11 has a circular end surface 11A and a spherical surface 11B extending from a connecting surface 10A to the body portion 10 to the end surface 11A. The connecting surface 10A and the end surface 11A with the body portion 10 are planes orthogonal to the axis 10B of the body portion 10. In the present embodiment, the head portion 11 is a sphere segment obtained by cutting a sphere having a diameter R11 with two parallel connecting surfaces 10A and an end surface 11A. The spherical surface 11B is a side surface portion of the spherical segment.
上記アンカーピン１を用いたピンニング工法では、図２（Ａ）に示すように、まず、躯体３の表面に貼付けモルタル４Ａやタイル４Ｂなどの仕上げ材４が設けられた壁体２の要補修箇所に対し、仕上げ材４を貫通して躯体３に深さＤ５の穿孔穴５を形成する。その後、同図（Ｂ）に示すように穿孔穴５の開口縁部５Ａから球状面取りビット７を用いて深さＤ７まで面取りを行い、同図（Ｃ）に示すように開口縁部５Ａに球帯状の面取り部５Ｂを形成する。 In the pinning method using the anchor pin 1, as shown in FIG. 2 (A), first, the repair-required portion of the wall body 2 provided with the finishing material 4 such as the mortar 4A and the tile 4B attached to the surface of the skeleton 3 On the other hand, a hole 5 having a depth of D5 is formed in the skeleton 3 through the finishing material 4. After that, as shown in FIG. 3B, chamfering is performed from the opening edge 5A of the perforated hole 5 to a depth D7 using a spherical chamfering bit 7, and a ball is formed in the opening edge 5A as shown in FIG. A strip-shaped chamfered portion 5B is formed.
球状面取りビット７の先端部の球状の直径Ｒ７は、使用するアンカーピン１の頭部１１の球帯状面１１Ｂの直径Ｒ１と同一径とすることで、球帯状の面取り部５Ｂの内径Ｒ３は、球帯状面１１Ｂの直径Ｒ１と同一径とする。これにより、アンカーピン１を穿孔穴５に挿入した際、アンカーピン１の頭部１１の球帯状面１１Ｂと穿孔穴５の球帯状の面取り部５Ｂとが面接触するようになる。 The spherical diameter R7 at the tip of the spherical chamfer bit 7 has the same diameter as the diameter R1 of the spherical surface 11B of the head 11 of the anchor pin 1 to be used, so that the inner diameter R3 of the spherical chamfer 5B is set to the same diameter. The diameter is the same as the diameter R1 of the spherical surface 11B. As a result, when the anchor pin 1 is inserted into the drilling hole 5, the spherical surface 11B of the head portion 11 of the anchor pin 1 and the spherical chamfered portion 5B of the drilling hole 5 come into surface contact with each other.
次に、図３（Ａ）に示すように、穿孔穴５に接着剤６を注入して、穿孔穴５内および仕上げ材４の浮きの部分に接着剤６を行き渡らせる。そして、同図（Ｂ）に示すように、アンカーピン１を穿孔穴５の奥まで挿入する。これにより、同図（Ｃ）に示すように、アンカーピン１の頭部１１の球帯状面１１Ｂと穿孔穴５の球帯状の面取り部５Ｂとが面接触し、仕上げ材４はアンカーピン１により広い面で支持される。 Next, as shown in FIG. 3A, the adhesive 6 is injected into the perforated hole 5 to spread the adhesive 6 in the perforated hole 5 and in the floating portion of the finishing material 4. Then, as shown in FIG. 3B, the anchor pin 1 is inserted all the way into the drilling hole 5. As a result, as shown in FIG. 3C, the spherical surface 11B of the head 11 of the anchor pin 1 and the spherical chamfered portion 5B of the perforated hole 5 come into surface contact with each other, and the finishing material 4 is brought into surface contact by the anchor pin 1. It is supported in a wide range.
最後に、アンカーピン１の頭部１１の端面１１Ａと仕上げ材４の表面４Ｃとの隙間をパテ８で埋め、仕上げ材４の表面４Ｃと同色のタッチアップ塗料で塗って仕上げる。なお、パテ８はマヨネーズ状のものを用いて隙間にすり込むようにして施工することが望ましい。また、パテ８は紫外線硬化型や光硬化型のものを用いることが望ましい。 Finally, the gap between the end surface 11A of the head 11 of the anchor pin 1 and the surface 4C of the finishing material 4 is filled with putty 8 and painted with a touch-up paint of the same color as the surface 4C of the finishing material 4 to finish. It is desirable to use a mayonnaise-like putty 8 and rub it into the gap. Further, it is desirable to use a putty 8 of an ultraviolet curable type or a photocurable type.
なお、前述の穿孔穴５の深さＤ５は、アンカーピン１を穿孔穴５に挿入して、アンカーピン１の頭部１１の球帯状面１１Ｂと穿孔穴５の球帯状の面取り部５Ｂとを面接触させた際に、胴体部１０の全体が穿孔穴５内に収容される深さとする。また、面取りの深さＤ７は、頭部１１の端面１１Ａが仕上げ材４の表面４Ｃとの間に隙間が形成され、パテ８により頭部１１を埋込み可能な深さとする。 The depth D5 of the perforated hole 5 is such that the anchor pin 1 is inserted into the perforated hole 5 and the spherical surface 11B of the head 11 of the anchor pin 1 and the spherical chamfered portion 5B of the perforated hole 5 are formed. The depth is such that the entire body portion 10 is accommodated in the perforated hole 5 when the body is brought into surface contact. The chamfering depth D7 is such that the end surface 11A of the head 11 is formed with a gap between the end surface 11A and the surface 4C of the finishing material 4, and the head 11 can be embedded by the putty 8.
以上のように、本実施形態におけるアンカーピン１を用いたピンニング工法によれば、アンカーピン１の頭部１１の球帯状面１１Ｂと穿孔穴５の球帯状の面取り部５Ｂとが面接触し、仕上げ材４はアンカーピン１により広い面で支持されるので支持強度が向上する。また、このピンニング工法では、図５に示すように穿孔穴５の軸線５Ｃに対してアンカーピン１が斜めに挿入されたとしても、アンカーピン１の頭部１１の球帯状面１１Ｂと穿孔穴５の球帯状の面取り部５Ｂとの面接触の状態が維持される。したがって、アンカーピン１の頭部１１と穿孔穴５の開口縁部との接触面積を広く維持することができ、アンカーピン１による仕上げ材４の支持強度を維持することができる。 As described above, according to the pinning method using the anchor pin 1 in the present embodiment, the spherical surface 11B of the head 11 of the anchor pin 1 and the spherical chamfered portion 5B of the perforated hole 5 are in surface contact with each other. Since the finishing material 4 is supported by the anchor pin 1 on a wide surface, the supporting strength is improved. Further, in this pinning method, even if the anchor pin 1 is inserted obliquely with respect to the axis 5C of the drilling hole 5 as shown in FIG. 5, the spherical surface 11B and the drilling hole 5 of the head 11 of the anchor pin 1 The state of surface contact with the spherical chamfered portion 5B is maintained. Therefore, the contact area between the head portion 11 of the anchor pin 1 and the opening edge portion of the drilled hole 5 can be maintained wide, and the supporting strength of the finishing material 4 by the anchor pin 1 can be maintained.
次に、本発明のアンカーピンの別の実施形態について説明する。図６は本発明の別の実施形態におけるアンカーピンの側面図、図７は図６のアンカーピンを分解した状態を示す部分斜視図、図８は図６のアンカーピンのキャップを首振りした状態を示す部分側面図、図９は図８の縦断面図、図１０は図６のアンカーピンの挿入工程を示す説明図、図１１はアンカーピン挿入後の状態を示す部分拡大図である。 Next, another embodiment of the anchor pin of the present invention will be described. 6 is a side view of the anchor pin according to another embodiment of the present invention, FIG. 7 is a partial perspective view showing a state in which the anchor pin of FIG. 6 is disassembled, and FIG. 8 is a state in which the cap of the anchor pin of FIG. 6 is swung. 9 is a vertical cross-sectional view of FIG. 8, FIG. 10 is an explanatory view showing an anchor pin insertion step of FIG. 6, and FIG. 11 is a partially enlarged view showing a state after the anchor pin is inserted.
図６に示すアンカーピン９は、アンカーピン本体としての前述のアンカーピン１と、アンカーピン１の端部の球帯状の頭部１１に嵌合されるキャップ１２とから構成される。キャップ１２は、アンカーピン１の頭部１１に嵌合された状態において、アンカーピン９の頭部を形成し、前述の穿孔穴５の球帯状の面取り部５Ｂに面接触する球帯状面１２Ａを有する。 The anchor pin 9 shown in FIG. 6 is composed of the above-mentioned anchor pin 1 as an anchor pin main body and a cap 12 fitted to a spherical head portion 11 at the end of the anchor pin 1. The cap 12 forms the head of the anchor pin 9 in a state of being fitted to the head 11 of the anchor pin 1, and has a spherical surface 12A that makes surface contact with the spherical chamfered portion 5B of the above-mentioned drilling hole 5. Have.
キャップ１２は、アンカーピン１の頭部１１に嵌合される凹部１２Ｂを有する。凹部１２Ｂは内面がアンカーピン１の頭部１１に面接触する球帯状面となっている。また、キャップ１２には、凹部１２Ｂの開口を拡げてアンカーピン１の頭部１１に嵌合させるための割り１２Ｃが２箇所に形成されている。 The cap 12 has a recess 12B that fits into the head 11 of the anchor pin 1. The concave portion 12B has a spherical band-shaped surface whose inner surface is in surface contact with the head portion 11 of the anchor pin 1. Further, the cap 12 is formed with two splits 12C for expanding the opening of the recess 12B and fitting it to the head 11 of the anchor pin 1.
このアンカーピン９では、図８および図９に示すように、アンカーピン１の頭部１１に首振り可能なキャップ１２が嵌合した状態となるため、アンカーピン１の軸線１０Ｂとキャップ１２の端面１２Ｄとが直交しない場合、すなわち、アンカーピン１が挿入される穿孔穴５がタイル４Ｂなどの仕上げ材４と直交しない場合にも対応することができる。 In the anchor pin 9, as shown in FIGS. 8 and 9, the swingable cap 12 is fitted to the head 11 of the anchor pin 1, so that the axis 10B of the anchor pin 1 and the end face of the cap 12 are fitted. It is also possible to deal with the case where the anchor pin 1 is not orthogonal to the 12D, that is, the hole 5 into which the anchor pin 1 is inserted is not orthogonal to the finishing material 4 such as the tile 4B.
このアンカーピン９は、図１０に示すように接着剤６を注入した穿孔穴５に挿入すると、キャップ１２の球帯状面１２Ａが穿孔穴５の球帯状の面取り部５Ｂに面接触する。このアンカーピン９では、アンカーピン１（アンカーピン本体）が穿孔穴５に対して斜めに挿入されてもキャップ１２が首振り可能であるため、キャップ１２の端面１２Ｄは仕上げ材４の表面４Ｃと平行を維持できる。 When the anchor pin 9 is inserted into the perforated hole 5 into which the adhesive 6 is injected as shown in FIG. 10, the spherical surface 12A of the cap 12 comes into surface contact with the spherical chamfered portion 5B of the perforated hole 5. In this anchor pin 9, the cap 12 can swing even if the anchor pin 1 (anchor pin body) is inserted diagonally into the drilling hole 5, so that the end surface 12D of the cap 12 is the surface 4C of the finishing material 4. Can be kept parallel.
そのため、キャップ１２の端面１２Ｄが仕上げ材４の表面４Ｃと面一となるように、前述の面取りの深さＤ７を調整することで、パテ８を使用することが不要となる。この場合、キャップ１２の端面１２Ｄを仕上げ材４の表面４Ｃと同色のタッチアップ塗料で塗って仕上げるようにすれば良い。 Therefore, by adjusting the chamfering depth D7 described above so that the end surface 12D of the cap 12 is flush with the surface 4C of the finishing material 4, it is not necessary to use the putty 8. In this case, the end surface 12D of the cap 12 may be painted with a touch-up paint of the same color as the surface 4C of the finishing material 4 to finish.
なお、前述のアンカーピン１を用いたピンニング工法においても、アンカーピン１の頭部１１の端面１１Ａが仕上げ材４の表面４Ｃと面一となるように、穿孔穴５の深さＤ５を調整することで、パテ８を使用することが不要となる。この場合、アンカーピン１の頭部１１の端面１１Ａを仕上げ材４の表面４Ｃと同色のタッチアップ塗料で塗って仕上げるようにすれば良い。 Also in the pinning method using the anchor pin 1 described above, the depth D5 of the drilling hole 5 is adjusted so that the end surface 11A of the head 11 of the anchor pin 1 is flush with the surface 4C of the finishing material 4. This eliminates the need to use the putty 8. In this case, the end surface 11A of the head 11 of the anchor pin 1 may be painted with a touch-up paint of the same color as the surface 4C of the finishing material 4 to finish.
