Description

本発明は、梁や桁同士又は梁と柱とを接合する際に、梁や桁の端部を柱や橋脚等の所定の受部に載置する載置工法及びその接合構造に関する。   The present invention relates to a mounting method for mounting an end of a beam or girder on a predetermined receiving portion such as a column or a bridge pier when joining beams or girders, or a beam and a column, and a joining structure thereof.

例えば、特許文献1に示すように、橋梁の桁同士を接合する際は、接合する桁の端部を橋脚上のそれぞれの所定の位置に載置し、この桁間にコンクリート等の硬化材を充填して桁同士を接続する工法が用いられている。   For example, as shown in Patent Document 1, when joining bridge girders, the ends of the girders to be joined are placed at predetermined positions on a bridge pier, and a hardening material such as concrete is placed between the girders. A method of filling and connecting the girders is used.

この桁を橋脚上の所定の位置に載置するには、まず、クレーンで桁を吊り上げて橋脚上まで移動させて、次に、桁を降下しつつ、桁の長手方向に対して直交する直交方向の位置及び傾斜を微調整して、桁の端部を橋脚上に載置する。桁及び橋脚は、それぞれ共に精度良く構築されていても、桁の下面や橋脚の上面には微少な凹凸が存在するので、桁を橋脚上に載置した後に桁の高さを微調整する作業を必ず行わなければならない。桁の高さの調整は、桁と橋脚との間にライナープレート等を挿入することにより行う。
昭60−208534号公報
To place this girder at a predetermined position on the pier, first lift the girder with a crane and move it to the pier, and then lower the girder while orthogonally intersecting the longitudinal direction of the girder. Finely adjust the position and inclination of the direction and place the end of the beam on the pier. Even if the girder and the pier are both constructed with high accuracy, there are slight irregularities on the lower surface of the girder and the upper surface of the pier, so the work of finely adjusting the height of the girder after placing the girder on the pier Must be done. The height of the girder is adjusted by inserting a liner plate or the like between the girder and the pier.
Sho 60-208534

しかしながら、上述した桁と橋脚との間にライナープレートを挿入して高さを調整する方法は、クレーンで桁を吊り上げなければならないので、再び、桁を橋脚上に載置する際には、上述した桁の直交方向の位置及び傾斜を再調整しなければならず、手間及び時間がかかるという問題点があった。   However, the method of adjusting the height by inserting the liner plate between the girder and the pier described above requires lifting the girder with a crane. Therefore, when placing the girder on the pier again, The position and inclination in the orthogonal direction of the girders must be readjusted, and there is a problem that it takes time and effort.

そこで、本発明は、上記のような従来の問題点に鑑みなされたものであって、梁や桁等の横部材を柱や橋脚等の所定の受け部に載置する際に、高さ調整が不要な載置工法及びその接合構造を提供することを目的とする。   Therefore, the present invention has been made in view of the conventional problems as described above, and the height adjustment is performed when a horizontal member such as a beam or a girder is placed on a predetermined receiving portion such as a column or a bridge pier. It is an object of the present invention to provide a mounting method and a joining structure thereof that do not require the above.

前記目的を達成するため、本発明の載置工法は、梁や桁等の横部材の端部を柱や橋脚等の所定の受部に載置する載置工法において、前記横部材の端部の所定の高さ位置に、その長手方向に突出するように設けられた載置側鋼板を、前記所定の受け部の上端部に、前記載置側鋼板と直交し、かつ上方に所定の長さだけ突出するように設けられた受け側鋼板の上に載置することを特徴とする(第1の発明)。   In order to achieve the above object, the mounting method of the present invention is a mounting method in which the end of a horizontal member such as a beam or a girder is mounted on a predetermined receiving part such as a column or a bridge pier. A mounting-side steel plate provided at a predetermined height position so as to protrude in the longitudinal direction is perpendicular to the mounting-side steel plate at the upper end portion of the predetermined receiving portion and has a predetermined length upward. It mounts on the receiving side steel plate provided so that it may protrude only (first invention).

本発明による載置工法によれば、梁や桁等の横部材の端部の所定の高さ位置に設けられた載置側鋼板を、柱や橋脚等の所定の受け部の上面に設けられた所定の長さの受け側鋼板上に載置するので、横部材を常に所定の受け部から一定の高さ位置に設置することができる。すなわち、横部材の高さを調整する必要が無いので、クレーンで横部材を吊り上げてライナープレート等を設置する手間を省くことができる。   According to the mounting method according to the present invention, the mounting-side steel plate provided at the predetermined height position of the end of the horizontal member such as the beam or the girder is provided on the upper surface of the predetermined receiving portion such as the column or the pier. In addition, since it is placed on the receiving side steel plate having a predetermined length, the transverse member can always be installed at a certain height position from the predetermined receiving portion. That is, since it is not necessary to adjust the height of the transverse member, it is possible to save the trouble of lifting the transverse member with a crane and installing the liner plate and the like.

第2の発明の載置工法は、前記所定の受け部に、前記横部材の端部を前記長手方向に対して直交する直交方向に移動するための移動手段と、前記横部材の端部を前記直交方向に傾斜するための傾斜手段とを設け、この移動手段及び傾斜手段にて前記横部材の前記直交方向の位置及び傾斜を調整することとしてもよい。   In the mounting method of the second invention, the predetermined receiving portion includes a moving means for moving an end portion of the transverse member in an orthogonal direction perpendicular to the longitudinal direction, and an end portion of the transverse member. It is good also as providing the inclination means for inclining in the said orthogonal direction, and adjusting the position and inclination of the said orthogonal | vertical direction of the said horizontal member with this moving means and inclination means.

本発明による載置工法によれば、横部材の載置側鋼板は所定の受け部の受け側鋼板と点的に接触しているので、横部材を容易に移動手段で直交方向に移動させて所定の位置に設置することができる。   According to the mounting method according to the present invention, the mounting-side steel plate of the transverse member is in point contact with the receiving-side steel plate of the predetermined receiving portion, so that the transverse member can be easily moved in the orthogonal direction by the moving means. It can be installed at a predetermined position.

また、横部材の載置側鋼板は所定の受け部の受け側鋼板と点的に接触しているので、横部材を容易に傾斜手段で直交方向に傾けて所定の傾斜にすることができる。   In addition, since the mounting side steel plate of the horizontal member is in point contact with the receiving side steel plate of the predetermined receiving portion, the horizontal member can be easily tilted in the orthogonal direction by the tilting means to have a predetermined inclination.

さらに、所定の受け部に設置された移動手段や傾斜手段は、横部材と接続されているので、横部材が所定の受け部から滑り落ちることを防止できる。従来は、橋脚の上面の面積が狭くて、桁の下面と橋脚の上面との接触面積が小さい場合には、桁が滑り落ちる可能性があるため、橋脚の上端部に桁を支持するための仮設ブラケットを設置しなければならなかったが、本発明の移動手段や傾斜手段を用いることにより、所定の受け部の面積が狭くても、仮設ブラケットを設置する必要が無い。したがって、仮設ブラケットの着脱作業の手間が省けるので、効率的に載置作業を実施することができる。   Further, since the moving means and the tilting means installed in the predetermined receiving portion are connected to the horizontal member, it is possible to prevent the horizontal member from sliding off from the predetermined receiving portion. Conventionally, when the area of the upper surface of the pier is small and the contact area between the lower surface of the girder and the upper surface of the pier is small, the girder may slide down, so a temporary structure for supporting the girder at the upper end of the pier Although the bracket had to be installed, the temporary bracket need not be installed even if the area of the predetermined receiving portion is small by using the moving means and the tilting means of the present invention. Therefore, since the labor of attaching and detaching the temporary bracket can be saved, the placing operation can be performed efficiently.

第3の発明の接合構造は、梁や桁等の横部材同士を接続するための接合構造であって、所定の間隔を隔てて対向配置されている前記横部材の当該所定の間隔側の端部の所定の高さ位置に、その長手方向に突出するように設けられた載置側鋼板が、前記横部材の端部を支持する柱や橋脚等の所定の受け部の上端部に、前記載置側鋼板と直交し、かつ上方に所定の長さだけ突出するように設けられた受け側鋼板の上に載置され、対向配置された前記横部材間の前記所定の間隔には、コンクリート等の硬化材が充填されてなることを特徴とする。   A joining structure of a third invention is a joining structure for connecting transverse members such as beams and girders, and is an end of the transverse member that is disposed opposite to the prescribed interval with a prescribed interval. A mounting-side steel plate provided at a predetermined height position of the portion so as to protrude in the longitudinal direction is placed in front of an upper end portion of a predetermined receiving portion such as a column or a pier that supports the end portion of the transverse member. The predetermined distance between the transverse members placed on and opposed to the receiving-side steel plate orthogonal to the placement-side steel plate and projecting upward by a predetermined length is concrete. It is characterized by being filled with a curing material such as.

本発明による接合構造によれば、梁や桁等の横部材の端部の所定の高さ位置に設けられた載置側鋼板を、柱や橋脚等の所定の受け部の上端部に設けられた所定の長さの受け側鋼板上に載置するので、横部材を常に所定の受け部から一定の高さ位置に設置することができる。すなわち、横部材の高さを調整する必要が無いので、クレーンで梁や桁を吊り上げてライナープレートを設置する手間を省くことができる。   According to the joining structure of the present invention, the mounting-side steel plate provided at a predetermined height position of the end portion of a horizontal member such as a beam or a girder is provided at the upper end portion of a predetermined receiving portion such as a column or a bridge pier. In addition, since it is placed on the receiving side steel plate having a predetermined length, the transverse member can always be installed at a certain height from the predetermined receiving portion. That is, since it is not necessary to adjust the height of the transverse member, it is possible to save the trouble of lifting the beam or girder with a crane and installing the liner plate.

第4の発明の接合構造は、梁と柱とを接続するための接合構造であって、梁の端部の所定の高さ位置に、その長手方向に突出するように設けられた載置側鋼板が、梁の端部を支持する柱の上端部に、前記載置側鋼板と直交し、かつ上方に所定の長さだけ突出するように設けられた受け側鋼板の上に載置され、前記載置側鋼板及び前記受け側鋼板を覆うようにコンクリート等の硬化材が打設されてなることを特徴とする。   The joint structure of the fourth invention is a joint structure for connecting a beam and a column, and is provided at a predetermined height position of an end portion of the beam so as to protrude in the longitudinal direction. The steel plate is placed on the upper end of the column that supports the end of the beam, on the receiving side steel plate that is orthogonal to the mounting side steel plate and is provided to protrude upward by a predetermined length, A hardened material such as concrete is placed so as to cover the mounting side steel plate and the receiving side steel plate.

本発明による接合構造によれば、梁の端部の所定の高さ位置に設けられた載置側鋼板を、柱の上端部に設けられた所定の長さの受け側鋼板上に載置するので、梁を常に柱の上端から一定の高さ位置に設置することができる。すなわち、梁の高さを調整する必要が無い。   According to the joining structure of the present invention, the placing side steel plate provided at a predetermined height position of the end portion of the beam is placed on the receiving side steel plate having a predetermined length provided at the upper end portion of the column. Therefore, the beam can always be installed at a certain height from the upper end of the column. That is, there is no need to adjust the height of the beam.

本発明の載置工法を用いることにより、梁や桁等の横部材を柱や橋脚等の所定の受け部に載置する際に横部材の高さ調整が不要となる。   By using the mounting method of the present invention, it is not necessary to adjust the height of the horizontal member when mounting the horizontal member such as a beam or girder on a predetermined receiving portion such as a column or a pier.

図11は、梁17、18を柱19に載置している状態を示す図である。図11に示すように、仮固定治具21の固定手段22は、アングルからなり、ボルトにて柱19の上面19aに固定される。
Next, a construction method for constructing the joint structure according to this embodiment will be described.
FIG. 11 is a view showing a state in which the beams 17 and 18 are placed on the column 19. As shown in FIG. 11, the fixing means 22 of the temporary fixing jig 21 has an angle and is fixed to the upper surface 19 a of the column 19 with a bolt.

クレーン等で吊り上げた梁17を降下させて、載置側鋼板3を受け側鋼板20上に載置し、仮固定治具21の移動手段14、傾斜手段15をそれぞれ角形鋼管10に接続する。また、梁18の載置側鋼板4も上記と同様に、受け側鋼板20上に載置する。両方の梁17、18の載置側鋼板3、4は、第一実施形態と同様に、それぞれ受け側鋼板20に点的に接触している。   The beam 17 lifted by a crane or the like is lowered to place the placing-side steel plate 3 on the receiving-side steel plate 20, and the moving means 14 and the tilting means 15 of the temporary fixing jig 21 are connected to the square steel pipe 10, respectively. Further, the placing side steel plate 4 of the beam 18 is also placed on the receiving side steel plate 20 in the same manner as described above. The mounting-side steel plates 3 and 4 of both beams 17 and 18 are in point contact with the receiving-side steel plate 20 in the same manner as in the first embodiment.

移動手段14及び傾斜手段15をそれぞれ伸縮して、両方の梁17、18を設計等で定められた所定の位置及び所定の傾斜になるように調整する。
そして、載置側鋼板3、4及び受け側鋼板20等を覆うようにコンクリート等の硬化材7を打設し、両方の梁17、18を一体化する。
The moving means 14 and the tilting means 15 are expanded and contracted to adjust both the beams 17 and 18 so as to have a predetermined position and a predetermined inclination determined by design or the like.
Then, a hardening material 7 such as concrete is placed so as to cover the mounting side steel plates 3 and 4 and the receiving side steel plate 20 and the like, and both the beams 17 and 18 are integrated.

次に、本発明の第三実施形態について説明する。
図12は、本発明の第三実施形態に係る梁17と柱19との接合構造を示す斜視図である。
Next, a third embodiment of the present invention will be described.
FIG. 12 is a perspective view showing a joint structure between the beam 17 and the column 19 according to the third embodiment of the present invention.

図12に示すように、梁17と柱19とを接続する接合部は、梁17の端部の所定の高さ位置に、その長手方向に突出するように設けられた載置側鋼板3が、柱19の上端部に、載置側鋼板3と直交するように設けられた受け側鋼板6の上に載置されている。梁17と柱19との接合部は、載置側鋼板3及び受け側鋼板6等を覆うようにコンクリート等の硬化材7が打設され、梁17と柱19とが一体化している。   As shown in FIG. 12, the connecting portion connecting the beam 17 and the column 19 has a mounting-side steel plate 3 provided at a predetermined height position at the end of the beam 17 so as to protrude in the longitudinal direction. The upper end of the column 19 is placed on a receiving-side steel plate 6 provided so as to be orthogonal to the placing-side steel plate 3. At the joint between the beam 17 and the column 19, a hardening material 7 such as concrete is placed so as to cover the mounting side steel plate 3 and the receiving side steel plate 6, and the beam 17 and the column 19 are integrated.

次に、本実施形態に係る接合構造を構築する方法について説明する。
図13は、梁17を柱19に載置している状態を示す図である。図13に示すように、第一及び第二実施形態と同様に、クレーン等で吊り上げた梁17を降下させて、載置側鋼板3を受け側鋼板6上に載置し、移動手段14、傾斜手段15をそれぞれ角形鋼管10に接続する。
移動手段14及び傾斜手段15をそれぞれ伸縮して、梁17を設計等で定められた所定の位置及び所定の傾斜になるように調整する。
そして、載置側鋼板3及び受け側鋼板6等を覆うようにコンクリート等の硬化材7を打設し、梁17と柱19とを一体化する(図12参照)。
Next, a method for constructing the joint structure according to this embodiment will be described.
FIG. 13 is a diagram illustrating a state in which the beam 17 is placed on the column 19. As shown in FIG. 13, similarly to the first and second embodiments, the beam 17 lifted by a crane or the like is lowered and placed on the receiving side steel plate 6 on the receiving side steel plate 6, and the moving means 14, The inclination means 15 are connected to the square steel pipe 10 respectively.
The moving means 14 and the tilting means 15 are respectively expanded and contracted to adjust the beam 17 so as to have a predetermined position and a predetermined inclination determined by design or the like.
Then, a hardening material 7 such as concrete is placed so as to cover the mounting side steel plate 3 and the receiving side steel plate 6 and the like, and the beam 17 and the column 19 are integrated (see FIG. 12).

以上説明した各実施形態における載置工法によれば、梁17、18や桁1、2の端部の所定の高さ位置に設けられた載置側鋼板3、4を、柱19や橋脚5の上面19a、5aに設けられた所定の長さの受け側鋼板6、20上に載置するので、梁17、18や桁1、2を柱19や橋脚5の上端から常に一定の高さ位置に設置することができる。すなわち、梁17、18や桁1、2の高さを調整する必要が無いので、クレーンで梁17、18や桁1、2を吊り上げてライナープレートを設置して高さを調整する等の手間を省くことができる。   According to the mounting method in each embodiment described above, the mounting-side steel plates 3 and 4 provided at the predetermined height positions of the ends of the beams 17 and 18 and the girders 1 and 2 are connected to the columns 19 and the piers 5. Are placed on the receiving side steel plates 6 and 20 of a predetermined length provided on the upper surfaces 19a and 5a of the steel plate, so that the beams 17 and 18 and the girders 1 and 2 are always at a constant height from the upper ends of the columns 19 and the piers 5. Can be installed in position. That is, since it is not necessary to adjust the heights of the beams 17 and 18 and the girders 1 and 2, it is necessary to lift the beams 17 and 18 and the girders 1 and 2 with a crane and install a liner plate to adjust the height. Can be omitted.

梁17、18や桁1、2の載置側鋼板3、4が柱19や橋脚5の受け側鋼板6、20上に点的に載置しているので、梁17、18や桁1、2を容易に移動手段14で直交方向に移動させて所定の位置に設置することができる。   Since the placing-side steel plates 3 and 4 of the beams 17 and 18 and the girders 1 and 2 are placed on the pillars 19 and the receiving-side steel plates 6 and 20 of the pier 5 in a dotted manner, the beams 17 and 18 and the girders 1 and 2 2 can be easily moved in the orthogonal direction by the moving means 14 and installed at a predetermined position.

また、梁17、18や桁1、2の載置側鋼板3、4が柱19や橋脚5の受け側鋼板6、20に点的に載置しているので、梁17、18や柱19を容易に傾斜手段15で直交方向に傾けて所定の傾斜にすることができる。   Further, since the placing-side steel plates 3 and 4 of the beams 17 and 18 and the girders 1 and 2 are placed on the pillar 19 and the receiving-side steel plates 6 and 20 of the bridge pier 5 in a dotted manner, the beams 17 and 18 and the pillar 19 are placed. Can be easily tilted in the orthogonal direction by the tilting means 15 to obtain a predetermined tilt.

さらに、仮固定治具13に備えられた移動手段14や傾斜手段15は、梁17、18や桁1、2と接続されているので、梁17、18や桁1、2が柱19や橋脚5の上面19a、5aから滑り落ちることを防止できる。従来は、橋脚5の上面5aの面積が狭くて、桁1、2の下面1a、2aと橋脚5の上面5aとの接触面積が小さい場合には、桁1、2が滑り落ちる可能性があるため、橋脚5の上端部に桁1、2を支持するための仮設ブラケットを設置しなければならなかったが、本発明の移動手段14や傾斜手段15を用いることにより、柱19や橋脚5の上面19a、5aの面積が狭くても、仮設ブラケットを設置する必要が無い。したがって、仮設ブラケットの着脱作業の手間が省けるので、効率的に載置作業を実施することができる。   Further, since the moving means 14 and the tilting means 15 provided in the temporary fixing jig 13 are connected to the beams 17 and 18 and the girders 1 and 2, the beams 17 and 18 and the girders 1 and 2 are connected to the pillar 19 and the pier. 5 can be prevented from slipping down from the upper surfaces 19a, 5a. Conventionally, when the area of the upper surface 5a of the pier 5 is small and the contact area between the lower surfaces 1a and 2a of the girders 1 and 2 and the upper surface 5a of the pier 5 is small, the girders 1 and 2 may slide down. The temporary bracket for supporting the girders 1 and 2 had to be installed at the upper end of the pier 5, but by using the moving means 14 and the inclination means 15 of the present invention, the upper surface of the pillar 19 and the pier 5 Even if the areas 19a and 5a are small, there is no need to install a temporary bracket. Therefore, since the labor of attaching and detaching the temporary bracket can be saved, the placing operation can be performed efficiently.
