Description

この発明は、例えば鋼構造物を架設するときに使用した作業足場や吊りピース等の取付用穴の埋め戻しに使用する化粧栓、特に各種板厚の構造物に対する適用に関するものである。   The present invention relates to a makeup plug used for backfilling a mounting hole such as a working scaffold or a suspension piece used when laying a steel structure, for example, particularly to a structure having various plate thicknesses.

例えば橋梁構造物、特に吊橋や斜張橋の主塔構造物の塔頂部に作業足場を設けたり、補剛桁部に取り付けるフェアリングに架設用の吊りピースを設けている。この作業足場や吊りピースは主塔構造物本体やフェアリングに設けたボルト取付穴にボルトを挿入して固定している。この作業足場や吊りピースは工事終了後に撤去され、主塔構造物本体等に設けたボルト取付穴は化粧ボルトを挿入して埋め戻している。   For example, a working scaffold is provided at the top of a bridge structure, in particular, a main tower structure of a suspension bridge or cable-stayed bridge, or a suspension piece for installation is provided at a fairing attached to a stiffening girder. The work scaffold and the suspension piece are fixed by inserting bolts into bolt mounting holes provided in the main tower structure main body or fairing. The work scaffold and the suspension piece are removed after the construction is completed, and the bolt mounting holes provided in the main tower structure main body or the like are backfilled by inserting decorative bolts.

このボルト取付穴の埋め戻しに使用する化粧ボルトとして、以前には鋼製の摩擦接合用高力ボルトやトルシア型高力ボルトを使用し、塔頂クレーンや移動クレーンと搭乗設備を用いて塔外面や桁外面からボルト取付穴に高力ボルトを挿入し、内面にいる作業者がナットを取り付けて締め付け、埋め戻した高力ボルトやその近傍に錆び止め用の塗装を行っている。このため高力ボルトの挿入から塗装までの作業工程が長くなり、多くの費用がかかるため改善が望まれていた。   As the decorative bolts used for backfilling the bolt mounting holes, steel high-strength bolts for friction welding and torcia-type high-strength bolts were previously used. A high-strength bolt is inserted into the bolt mounting hole from the outer surface of the girder, and the worker on the inner surface attaches and tightens the nut, and the high-strength bolt that has been backfilled and its vicinity are coated to prevent rust. For this reason, the work process from the insertion of high-strength bolts to painting becomes longer and requires a lot of cost, so improvement has been desired.

この要望を満たすために、シリコーン樹脂等の可撓性を有するプラスチック材料やゴムで形成され、鋼構造物の作業足場や吊りピースの取付用穴等を短時間で効率良く埋め戻すことができる化粧栓が特許文献１や特許文献２及び特許文献３等に開示されている。   To meet this demand, makeup made of flexible plastic material such as silicone resin or rubber, which can efficiently backfill work scaffolds for steel structures, mounting holes for suspension pieces, etc. in a short time. The stopper is disclosed in Patent Document 1, Patent Document 2, Patent Document 3, and the like.

特許文献１に示された化粧栓１０ａは、図４（ａ）に示すように、埋め戻す穴の寸法に応じた外径と長さを有する軸部１１の両端に鍔１２が設けられ、挿入する側の中心には収縮用の穴１３を有し、図４（ｂ）に示すように、鋼構造物７の作業足場を撤去した後に残っているボルト取付穴８を埋め戻すとき、化粧栓１０ａをボルト取付穴８に圧入して封止している。   As shown in FIG. 4A, the cosmetic plug 10a shown in Patent Document 1 is provided with flanges 12 at both ends of a shaft portion 11 having an outer diameter and a length corresponding to the size of the backfill hole. A shrinking hole 13 is provided at the center of the side to be mounted, and as shown in FIG. 4B, when the bolt mounting hole 8 remaining after the working scaffold of the steel structure 7 is removed is refilled, 10a is press-fitted into the bolt mounting hole 8 and sealed.

特許文献２に示された化粧栓１０ｂは、図５（ａ）に示すように、埋め戻す穴の寸法に応じた外径と長さを有する軸部１１の両端に鍔１２，１２ａを設け、挿入側の軸部先端に小径部１３を形成し、鋼構造物７のボルト取付穴８を埋め戻すとき、図５（ｂ）に示すように、挿入側の鍔１２ａを反挿入方向に押し倒して小径部１３に沿わせて鋼構造物７のボルト取付穴８に圧入している。   As shown in FIG. 5A, the cosmetic plug 10b shown in Patent Document 2 is provided with flanges 12 and 12a at both ends of the shaft portion 11 having an outer diameter and a length corresponding to the size of the hole to be backfilled. When the small diameter portion 13 is formed at the distal end of the shaft portion on the insertion side and the bolt mounting hole 8 of the steel structure 7 is refilled, as shown in FIG. 5 (b), the insertion side flange 12a is pushed down in the anti-insertion direction. Along the small diameter portion 13, the steel structure 7 is press-fitted into the bolt mounting hole 8.

特許文献３に示された化粧栓１０ｃは、図６（ａ）に示すように、埋め戻す穴の直径より十分に細い軸部１１ａの打ち込み側に円板状の鍔１２を設け、挿入側には中央部が丸く膨らんで外周部が薄くなった笠状の鍔１２ａを設け、鋼構造物７のボルト取付穴８を埋め戻すとき、図６（ｂ）に示すように、挿入側の鍔１２ａを反挿入方向に押し倒して小径の軸部１１ａに沿わせて鋼構造物７のボルト取付穴８に圧入している。
特開２００１−１０７５６２号公報 実開昭５５−１１０６６６号公報 実開平５−７１３４７号公報 As shown in FIG. 6 (a), the cosmetic plug 10c shown in Patent Document 3 is provided with a disk-shaped ridge 12 on the driving side of the shaft portion 11a that is sufficiently narrower than the diameter of the hole to be filled, and on the insertion side. Is provided with a cap-shaped rod 12a having a rounded central portion and a thin outer peripheral portion, and when the bolt mounting hole 8 of the steel structure 7 is backfilled, as shown in FIG. Is pushed into the bolt insertion hole 8 of the steel structure 7 along the small diameter shaft portion 11a.

鋼構造物は種々の板厚の材料が使用され、異なる板厚の鋼構造物に設けられたボルト取付穴をプラスチック材料やゴムで形成された化粧栓で埋め戻すためには、板厚に応じた長さの化粧栓を作製する必要がある。この板厚は１ｍｍ単位で異なり、化粧栓を各種板厚の鋼構造物に対応させるためには、１ｍｍ単位で長さが異なる化粧栓を作製する必要がある。このため化粧栓を作製する金型が多数必要になり、金型制作費が化粧栓のコストアップにつながってしまう。   Various steel plate materials are used for steel structures. Depending on the plate thickness, the bolt mounting holes provided in steel plates of different plate thicknesses can be backfilled with plastic plugs made of plastic material or rubber. It is necessary to make a lengthy makeup plug. The plate thickness varies in units of 1 mm, and in order to make the cosmetic plug correspond to steel structures having various plate thicknesses, it is necessary to produce cosmetic plugs having different lengths in units of 1 mm. For this reason, many molds for producing the cosmetic plug are required, and the mold production cost leads to an increase in the cost of the cosmetic plug.

また、近年は鋼構造物の板厚が例えば４０ｍｍ以上と厚くなる傾向にある。図７（ａ）に示すように、板厚ｔが厚くなった鋼構造物７に設けられたボルト取付穴８を、可撓性のプラスチック材料やゴムで形成され、板厚ｔに合った長さの軸部１１を有する化粧栓１０で埋め戻すとき、化粧栓１０をボルト取付穴８に押し込んでいるとき、押し込んでいる鍔１２と軸部１１全体に摩擦力が作用し、この摩擦力が次第に大きくなり、押し込み途中で、図７（ｂ）に示すように、ボルト取付穴８の挿入部で軸部１１が膨れ上がりボルト取付穴８に押し込むことができなくなったり、図７（ｃ）に示すように、軸部１１がボルト挿入側で座屈して化粧栓１０をボルト取付穴８に押し込むことができなくなってしまうという短所がある。   In recent years, the steel structure tends to be thicker, for example, 40 mm or more. As shown in FIG. 7 (a), the bolt mounting hole 8 provided in the steel structure 7 having a thick plate thickness t is formed of a flexible plastic material or rubber and has a length suitable for the plate thickness t. When the makeup plug 10 having the shaft portion 11 is backfilled, when the makeup plug 10 is pushed into the bolt mounting hole 8, a frictional force acts on the pressed flange 12 and the whole shaft portion 11, and this frictional force is As shown in FIG. 7B, the shaft portion 11 swells up at the insertion portion of the bolt mounting hole 8 and cannot be pushed into the bolt mounting hole 8 as shown in FIG. 7B. As shown, there is a disadvantage that the shaft portion 11 is buckled on the bolt insertion side and the cosmetic plug 10 cannot be pushed into the bolt mounting hole 8.

この発明は、このような短所を改善し、各種板厚の構造物に適用することができるとともに安価で提供することができる化粧栓を得ることを目的とするものである。   An object of the present invention is to improve such disadvantages and to obtain a cosmetic plug that can be applied to structures having various plate thicknesses and can be provided at low cost.

この発明の化粧栓は、１対の栓本体と長さ調整軸とを有し、栓本体は、円柱状に形成された封止部と、該封止部の一方の端部に設けられた円板状の鍔を有し、シリコーン樹脂や耐熱性と機械強度を有するプラスチック材料又は硬質ゴムにより形成され、封止部は埋め戻す穴の寸法に応じた外径と一定長さを有し、鍔と反対側の面に長さ調整軸を連結する連結穴が一定深さで設けられ、鍔は外径が封止部の外径より若干大きく形成され、長さ調整軸は、金属材料やプラスチック材料あるいは木材等の剛性を有する材料で形成された丸棒又は角棒からなり、両端部を封止部の連結穴に挿入して１対の栓本体を連結することを特徴とする。   The cosmetic plug of the present invention has a pair of plug main bodies and a length adjusting shaft, and the plug main body is provided at a sealing portion formed in a columnar shape and at one end of the sealing portion. It has a disc-shaped ridge, is formed of a silicone resin, a plastic material having heat resistance and mechanical strength, or a hard rubber, and the sealing portion has an outer diameter and a certain length according to the size of the hole to be backfilled, A connecting hole for connecting the length adjustment shaft to the surface opposite to the flange is provided at a certain depth, and the flange has an outer diameter slightly larger than the outer diameter of the sealing portion. It consists of a round bar or a square bar formed of a plastic material or a rigid material such as wood, and is characterized in that a pair of plug bodies are connected by inserting both end portions into connection holes of the sealing portion.

前記長さ調整軸の長さを埋め戻す穴を有する部材の板厚に応じて可変する。   The length of the length adjusting shaft is variable according to the thickness of the member having a hole for backfilling.

また、前記長さ調整軸の封止部の連結穴に挿入する部分にねじ又は円周に沿った複数の溝を形成し、封止部と接着剤で連結することが望ましい。   Moreover, it is desirable to form a plurality of grooves along the screw or the circumference in a portion to be inserted into the connecting hole of the sealing portion of the length adjusting shaft, and to connect the sealing portion with an adhesive.

この発明の化粧栓は、１対の栓本体を長さ調整軸で連結して構成したから、一方の栓本体を埋め戻す穴に圧入した後、さらに化粧栓を埋め戻す穴に押し込むとき、化粧栓の長さ調整軸に連結した他方の栓本体が埋め戻す穴に達するまでは、先に押し込んだ栓本体だけが埋め戻す穴の内面に接触しているから、化粧栓と埋め戻す穴との間に作用する摩擦力を低減して、化粧栓を容易に押し込むことができる。   Since the cosmetic plug of the present invention is configured by connecting a pair of plug bodies with a length adjusting shaft, when one of the plug bodies is press-fitted into the backfilling hole, the makeup plug is further pushed into the backfilling hole. Until the other plug body connected to the plug length adjustment shaft reaches the backfill hole, only the plug body that has been pushed in is in contact with the inner surface of the backfill hole. By reducing the frictional force acting between them, the cosmetic plug can be pushed in easily.

また、埋め戻す穴に押し込んだ栓本体と押し込み力を加える栓本体を剛性を有する長さ調整軸で連結しているから、座屈等の変形が生じることなく化粧栓を埋め戻す穴に押し込むことができ、埋め戻す穴を有する部材の板厚が厚くても安定して押し込むことができる。   In addition, since the plug body that is pushed into the backfill hole and the plug body that applies the pushing force are connected by a rigid length adjustment shaft, the cosmetic plug can be pushed into the backfill hole without deformation such as buckling. And can be pushed in stably even if the thickness of the member having the hole to be filled is thick.

さらに、化粧栓を埋め戻すに押し込んで、他方の栓本体を埋め戻す穴に押し込んでも、１対の栓本体間の長さ調整軸の部分には摩擦力が作用しないから、化粧栓全体に加えられる摩擦力を小さくすることができ、化粧栓を安定して押し込むことができる。   Furthermore, even if the makeup plug is pushed back to the back and the other plug body is pushed into the backfill hole, the frictional force does not act on the length adjusting shaft between the pair of plug bodies. The frictional force generated can be reduced, and the cosmetic plug can be pushed in stably.

また、長さ調整軸の長さを埋め戻す穴を有する部材の板厚に応じて可変することにより、埋め戻す穴の径が一定の場合は、部材の板厚が変わっても１対の栓本体を共通に使用することができ、１つの金型で多量の栓本体を作製することができ、栓本体の制作費を低減して化粧栓自体の低価格化を図ることができる。   Further, by changing the length of the length adjusting shaft in accordance with the thickness of the member having the hole to be backfilled, when the diameter of the backfilling hole is constant, a pair of plugs is provided even if the thickness of the member changes. The main body can be used in common, a large amount of the plug body can be manufactured with one mold, the production cost of the plug body can be reduced, and the price of the cosmetic plug itself can be reduced.

さらに、長さ調整軸の封止部の連結穴に挿入する部分にねじ又は円周に沿った複数の溝を形成し、封止部と接着剤で連結することにより、長さ調整軸と栓本体との接着強度をより高めることができ、化粧栓を埋め戻す穴に安定して押し込むことができるとともにメンテナンス時に容易に取り外すこともでできる。   Furthermore, the length adjusting shaft and the plug are formed by forming a plurality of grooves along the screw or the circumference in the portion to be inserted into the connecting hole of the sealing portion of the length adjusting shaft and connecting with the sealing portion with an adhesive. The adhesive strength with the main body can be further increased, and the cosmetic plug can be stably pushed into the hole for backfilling and can be easily removed during maintenance.

図１はこの発明の化粧栓の構成図である。図に示すように、化粧栓１は、１対の栓本体２が長さ調整軸３で連結されている。栓本体２は、円柱状に形成された封止部４と、封止部４の一方の端部に設けられた円板状の鍔５を有し、シリコーン樹脂や耐熱性と機械強度を有するプラスチック材料、例えばボリアミドやポリアセタール，変性ポリフェニレンオキサイド，ポリスルフォン，ポリカーボネート，ポリエチレンテフタレート，ポリブチレンテフタレートなど又は硬質ゴムにより形成されている。封止部４は鋼構造物の作業足場や吊りピース等の取付用穴等の径と同じか若干大きい外径Ｄと、一定長さＬ、例えばＬ＝２０ｍｍで形成され、図２の断面図に示すように、鍔５と反対側の面に長さ調整軸３を連結する連結穴６が一定深さＬ１で設けられている。鍔５は外径Ｄ１が封止部４の外径Ｄより若干、例えば１ｍｍ程度大きく形成され、外周部は面取りされ、外周側の厚さが次第に薄くなっている。   FIG. 1 is a configuration diagram of a cosmetic plug of the present invention. As shown in the figure, the cosmetic plug 1 has a pair of plug bodies 2 connected by a length adjusting shaft 3. The plug body 2 has a sealing part 4 formed in a columnar shape and a disk-like collar 5 provided at one end of the sealing part 4 and has silicone resin, heat resistance and mechanical strength. It is made of a plastic material such as polyamide, polyacetal, modified polyphenylene oxide, polysulfone, polycarbonate, polyethylene terephthalate, polybutylene terephthalate, or hard rubber. The sealing portion 4 is formed with an outer diameter D which is the same as or slightly larger than the diameter of a mounting hole for a work scaffold or a suspension piece of a steel structure, and a constant length L, for example, L = 20 mm, As shown in FIG. 5, a connecting hole 6 for connecting the length adjusting shaft 3 to the surface opposite to the flange 5 is provided at a constant depth L1. The flange 5 is formed such that the outer diameter D1 is slightly larger than the outer diameter D of the sealing portion 4, for example, about 1 mm, the outer peripheral portion is chamfered, and the outer peripheral thickness is gradually reduced.

長さ調整軸３は金属材料やプラスチック材料あるいは木材等の剛性を有する材料で形成された丸棒又は角棒からなり、両端部を封止部４の連結穴６に挿入して１対の栓本体２を連結する。この長さ調整軸３の長さＬｘはボルト取付穴を有する鋼構造物の板厚ｔと封止部４の長さＬ及び連結穴６の深さＬ１により定められる。   The length adjusting shaft 3 is composed of a round bar or a square bar made of a metal material, a plastic material, or a rigid material such as wood, and both ends thereof are inserted into the connecting holes 6 of the sealing portion 4 to form a pair of plugs. The main body 2 is connected. The length Lx of the length adjusting shaft 3 is determined by the plate thickness t of the steel structure having bolt mounting holes, the length L of the sealing portion 4, and the depth L1 of the connecting hole 6.

この化粧栓１を使用して、図３（ａ）に示すように、板厚ｔの鋼構造物７の作業足場等を撤去して残ったボルト取付穴８を埋め戻すときは、鋼構造物７の板厚ｔにより定められた長さＬｘの長さ調整軸３の両端部を封止部４の連結穴６に挿入して接着剤で固定して、鋼構造物７の板厚ｔに応じた長さの化粧栓１を作成する。この長さ調整軸３を封止部４の連結穴６に挿入して接着剤で固定するとき、長さ調整軸３の両端の接着部分にねじやスパイラル状の溝を設けたり、円周に沿った複数の溝を設けておくと、長さ調整軸３と栓本体２との接着強度をより高めることができる。   When this makeup plug 1 is used to remove the work scaffolding and the like of the steel structure 7 having a thickness t and refill the remaining bolt mounting holes 8 as shown in FIG. The both ends of the length adjusting shaft 3 having a length Lx determined by the plate thickness t of 7 are inserted into the connecting holes 6 of the sealing portion 4 and fixed with an adhesive, so that the plate thickness t of the steel structure 7 is obtained. A makeup plug 1 having a corresponding length is prepared. When the length adjusting shaft 3 is inserted into the connecting hole 6 of the sealing portion 4 and fixed with an adhesive, a screw or a spiral groove is provided in the adhesive portion at both ends of the length adjusting shaft 3 or the circumference is If a plurality of grooves are provided, the adhesive strength between the length adjusting shaft 3 and the plug body 2 can be further increased.

この化粧栓１により鋼構造物７に残ったボルト取付穴８を封止するときは、図３（ａ）に示すように、化粧栓１の一方の栓本体２をボルト取付穴８に圧入する。この栓本体２をボルト取付穴８に圧入するときに、栓本体２が弾性を有するシリコーン樹脂やボリアミド等のプラスチック材料又は硬質ゴムで形成されているとともに鍔５の外径Ｄ１が小さく、かつ外周部が面取りされて外周側の厚さが次第に薄くなっているから、ボルト取付穴８に容易に圧入することができる。化粧栓１の一方の栓本体２を圧入した後、さらに化粧栓１をボルト取付穴８に押し込むとき、化粧栓１の長さ調整軸３に連結した他方の栓本体２の封止部４がボルト取付穴８に達するまでは、先に押し込んだ栓本体４だけがボルト取付穴８の内面に接触しているから、化粧栓１とボルト取付穴８との間に作用する摩擦力を低減して、容易に押し込むことができる。また、ボルト取付穴８に押し込んだ栓本体２と押し込み力を加える栓本体２を剛性を有する長さ調整軸３で連結しているから、座屈等の変形が生じることなく化粧栓１をボルト取付穴８に押し込むことができる。   When sealing the bolt mounting hole 8 remaining in the steel structure 7 with the makeup plug 1, one plug body 2 of the makeup plug 1 is press-fitted into the bolt mounting hole 8 as shown in FIG. . When the plug body 2 is press-fitted into the bolt mounting hole 8, the plug body 2 is made of an elastic plastic material such as silicone resin or polyamide, or hard rubber, and the outer diameter D1 of the flange 5 is small, and the outer periphery. Since the portion is chamfered and the thickness on the outer peripheral side is gradually reduced, it can be easily press-fitted into the bolt mounting hole 8. After press-fitting one plug body 2 of the makeup plug 1, when the makeup plug 1 is further pushed into the bolt mounting hole 8, the sealing portion 4 of the other plug body 2 connected to the length adjustment shaft 3 of the makeup plug 1 is Until the bolt mounting hole 8 is reached, only the plug body 4 pushed in first is in contact with the inner surface of the bolt mounting hole 8, so that the frictional force acting between the cosmetic plug 1 and the bolt mounting hole 8 is reduced. Can be pushed in easily. In addition, since the plug body 2 that is pushed into the bolt mounting hole 8 and the plug body 2 that applies a pushing force are connected by a rigid length adjustment shaft 3, the cosmetic plug 1 can be bolted without deformation such as buckling. It can be pushed into the mounting hole 8.

さらに、化粧栓１をボルト取付穴８に押し込んで、図３（ｂ）に示すように、他方の栓本体２がボルト取付穴８に押し込まれると、化粧栓１とボルト取付穴８との間に作用する摩擦力が大きくなるが、栓本体２間の長さ調整軸３の部分には摩擦力が作用しないから、化粧栓１全体に加えられる摩擦力を小さくすることができ、化粧栓１を安定して押し込むことができる。   Further, when the cosmetic plug 1 is pushed into the bolt mounting hole 8 and the other plug body 2 is pushed into the bolt mounting hole 8 as shown in FIG. However, since the frictional force does not act on the portion of the length adjusting shaft 3 between the plug bodies 2, the frictional force applied to the entire cosmetic plug 1 can be reduced. Can be pushed in stably.

このように１対の栓本体２を長さ調整軸３で連結した化粧栓１で鋼構造物７のボルト取付穴８を埋め戻すことにより、ボルト取付穴８を有する鋼構造物７の板圧ｔが異なってもボルト取付穴８の径が一定の場合は、鋼構造物７の板圧ｔに応じた長さＬｘの長さ調整軸３を使用することにより、１対の栓本体２は共通に使用することができ、１つの金型で多量の栓本体２を作製することができ、栓本体２の制作費を低減して化粧栓１自体の低価格化を図ることができる。   Thus, by refilling the bolt mounting hole 8 of the steel structure 7 with the decorative plug 1 in which the pair of plug bodies 2 are connected by the length adjusting shaft 3, the plate pressure of the steel structure 7 having the bolt mounting hole 8 is filled. If the diameter of the bolt mounting hole 8 is constant even if t is different, the pair of plug bodies 2 can be obtained by using the length adjusting shaft 3 having a length Lx corresponding to the plate pressure t of the steel structure 7. It can be used in common, a large amount of the plug body 2 can be produced with one mold, the production cost of the plug body 2 can be reduced, and the price of the makeup plug 1 itself can be reduced.

前記説明では封止部４の長さＬを一定にした場合について説明したが、封止部４の外径Ｄに応じて長さＬを変えたり、封止部４の外径Ｄと同じ長さにしても良い。   In the above description, the case where the length L of the sealing portion 4 is made constant has been described. However, the length L is changed according to the outer diameter D of the sealing portion 4 or the same length as the outer diameter D of the sealing portion 4. It's okay.
