Description

本発明は、プレキャストコンクリート（ＰｒｅｃａｓｔＣｏｎｃｒｅｔｅ：以下、「ＰＣ」という）梁橋用仮設ブラケット及びその設置方法に係り、より具体的には、ＰＣ梁橋梁工事において簡単な組立、設置だけでＰＣ梁下端部に仮設ブラケットを完成させるが、前記仮設ブラケットの組立及び設置はＰＣ梁の上部で成されるので、高所作業での作業者の危険を回避することのできるＰＣ梁橋用仮設ブラケット及びその設置方法に関する。 The present invention relates to a precast concrete (hereinafter referred to as “PC”) beam bridge temporary bracket and its installation method, and more specifically, a PC beam lower end only by simple assembly and installation in PC beam bridge construction. The temporary bracket is completed at the part, but since the assembly and installation of the temporary bracket is performed at the upper part of the PC beam, the temporary bracket for the PC beam bridge and its It relates to the installation method.

一般的に、橋梁工事において築造された橋脚上部にスラブ打設をするための仮設方法は、橋梁の形式、現場の地形、構造物の高さ、橋梁下部の交通状態、工期及び工事費などの様々な総合的な要素を考慮して選定される。 In general, the temporary method for placing slabs on the upper part of the pier constructed during bridge construction is the type of bridge, the topography of the site, the height of the structure, the traffic condition at the bottom of the bridge, the construction period, and construction costs. It is selected considering various comprehensive factors.

従来、上部構造物を設置するための仮設工法としては、既に築造された橋脚の間にガーターを支持するための仮橋脚を設置し、橋脚下部地盤からシステムサポートなどを用いて床束を設置した後、その上部にスラブコンクリート打設のための鋳型を設置する床束工法、橋脚上部に木材の床束を設置する木材床束工法、または自動化された床束工法と鋳型を用いて１スパンを一度に施工する移動支保工工法（Ｍｏｖａｂｌｅｓｃａｆｆｏｌｄｉｎｇｓｙｓｔｅｍ）などが主に用いられてきた。 Conventionally, as a temporary construction method for installing the superstructure, a temporary pier for supporting the garter was installed between the already built piers, and a floor bundle was installed from the lower pier ground using system support etc. Later, a floor bundle construction method in which a mold for placing slab concrete is installed at the top, a wood floor bundle construction method in which a wood floor bundle is installed at the top of the pier, or an automated floor bundle construction method and mold is used for one span. A mobile scaffolding system that is constructed at a time has been mainly used.

ところが、橋脚下部地盤から床束を設置する床束工法は、仮設工事の高さが高くなると多くの資材と人手を要し、桁下空間が仮設空間として確保されなければならないという短所を伴い、床束及び鋳型の設置とは別に作業者の作業空間を確保するために、ガーター上部に突出した鉄筋で鉄線を連結した後、側面に下ろして単管パイプを縛って作業足場または安全網などの仮設材を設置する足場作業を先ず行わなければならない。 However, the floor bundling method that installs the floor bunch from the lower pier ground requires a lot of materials and manpower when the height of the temporary construction is high, with the disadvantage that the girder space must be secured as a temporary space, In order to secure the operator's work space separately from the installation of floor bundles and molds, after connecting the iron wire with the reinforcing bar protruding at the top of the garter, it is lowered to the side and tied to a single pipe to work scaffolding or safety net Scaffolding work to install temporary materials must be done first.

一方、木材床束を設置する工法は、ガーターとガーターとの間に作業台及びスラブ床束を所要間隔で設置した後、合板などでスラブ鋳型を組み立てる方式からなるが、木材床束は加工性が良くて初期費用が安い一方で部材自体の剛性が良くないため、狭い間隔で設置されなければならず、設置と解体作業が繰り返されると破損し易くなって結果的に仮設工事費を増大させる。 On the other hand, the method of installing a wood floor bundle consists of a method of assembling a slab mold with plywood after installing a work table and a slab floor bundle between the garter and the garter at the required intervals. The initial cost is good but the rigidity of the member itself is not good, so it must be installed at a narrow interval, and if it is repeatedly installed and dismantled, it will be easily damaged, resulting in an increase in temporary construction costs .

また、移動支保工工法では地盤から床束を設置する必要がなく、桁下空間や地盤などの条件に左右されずに施工することができるが、設置作業が複雑で、大型装備の投入が必須であり、橋梁の維持補修のための仮設工法としては適用することができない。 In addition, it is not necessary to install a floor bundle from the ground in the mobile support method, and construction can be performed regardless of conditions such as under-girder space and ground, but installation work is complicated and large equipment must be input. Therefore, it cannot be applied as a temporary construction method for bridge maintenance and repair.

よって、本発明者は、従来の欠点を解消しながら、ＰＣ梁下部で簡単に床束、作業足場または安全網を設置することができ、鋼材で製作されるので経済性のある作業が可能であり、橋梁の維持補修のための仮設作業にも適用できるように、下記実用新案文献１のＰＣ梁橋用仮設ブラケットを考案したが、前記ＰＣ梁橋用ブラケットは、ＰＣ梁の下部でしか仮設ブラケットの設置作業ができないため、高所での作業では危険が伴って作業者の安全を確保し難く、仮設装置設置時に別途の装備を要することから、これを解決することができる手段の開発が切実に求められていた。
（実用新案文献１）大韓民国登録実用新案第２４５２８４号 Therefore, the present inventor can easily install a floor bundle, a work scaffold or a safety net at the lower part of the PC beam while solving the conventional drawbacks, and can be operated economically because it is made of steel. Yes, the PC beam bridge temporary bracket of Utility Model Reference 1 below was devised so that it can be applied to temporary work for bridge maintenance and repair. However, the PC beam bridge bracket is temporarily installed only under the PC beam. Since the installation work of the bracket is not possible, it is difficult to ensure the safety of the worker at work in high places, and it is difficult to ensure the safety of the worker. It was urgently required.

図９は、橋梁のＰＣ梁２に本発明のＰＣ梁橋用仮設ブラケット１００が設置された状態を簡略に示す斜視図である。本発明のＰＣ梁橋用仮設ブラケット１００を利用した設置方法は、橋梁の橋脚１が完成し、橋脚１上部にＰＣ梁２が設置されると、ＰＣ梁橋用仮設ブラケット１００をＰＣ梁２上部に組み立てる段階と；前記組み立てられたＰＣ梁橋用仮設ブラケット１００をＰＣ梁２下端部まで斜めに下ろして前記ＰＣ梁２に位置させる段階と；前記ＰＣ梁橋用仮設ブラケット１００を、移動装置１４０を利用してＰＣ梁２下端部に密着させる段階と；を含む。 FIG. 9 is a perspective view schematically showing a state in which the PC beam bridge temporary bracket 100 of the present invention is installed on the PC beam 2 of the bridge. In the installation method using the temporary bracket 100 for PC beam bridge according to the present invention, when the bridge pier 1 is completed and the PC beam 2 is installed on the upper part of the pier 1, the temporary bracket 100 for PC beam bridge is installed on the upper part of the PC beam 2. Assembling the PC beam bridge temporary bracket 100 obliquely down to the lower end of the PC beam 2 and positioning the PC beam bridge temporary bracket 100 on the PC beam 2; A step of closely contacting the lower end of the PC beam 2 using

本発明のＰＣ梁橋用仮設ブラケット１００を利用した設置方法の詳細な具体例は次のとおりであり、以下、移動装置１４０は旗形移動装置１４１を基準に説明する。 A detailed specific example of the installation method using the temporary bracket 100 for PC beam bridge according to the present invention is as follows. Hereinafter, the moving device 140 will be described based on the flag-shaped moving device 141.

ＰＣ梁橋において下部構造物である橋脚工事が完成すると、橋脚１上部にＰＣ梁２が一定の間隔で設置され、上部構造物であるコンクリートスラブ打設のための仮設作業が開始される。 When the pier construction which is the lower structure is completed in the PC beam bridge, the PC beam 2 is installed at a predetermined interval on the upper part of the pier 1 and the temporary work for placing the concrete slab which is the upper structure is started.

前記完成した橋脚１のＰＣ梁２の上部で前記ＰＣ梁橋用仮設ブラケット１００の連結部材１３０を一対の支持部材１１０の水平部１１２に挿入する。その後、前記連結部材１３０の締結孔１３１と支持部材１１０の水平部１１２の結合溝１１２ａとが整合される所定の位置に、前記移動装置１４１の固定棒１４１ｄを挿入し、前記移動装置１４１の固定枠１２０の結合孔１２１と固定板１４１ｃの結合溝１４１ａとが整合される所定の位置に、固定ピン１４１ｂを挿入することにより、連結及び締結を完了する。この時、前記移動装置１４１の固定棒１４１ｄは、前記ＰＣ梁２の適正間隔を考慮して挿入位置が決定され、前記固定枠１２０の結合孔１２１と固定板１４１ｃの結合溝１４１ａとに挿入される固定ピン１４１ｂは、締結時に前記固定板１４１ｃの結合溝１４１ａに沿って上下方向に移動可能なくらいの余裕を置いて締結する。結局、図１及び図２のように、移動装置１４１が上に上がった状態で、固定枠１２０の固定ピン１４１ｂは固定板１４１ｃの結合溝１４１ａの下端部に位置しており、移動装置１４１が下がることによって、前記固定板１４１ｃの結合溝１４１ａは固定ピン１４１ｂを基準に下の対角線方向に移動し、これにより前記一対の支持部材１１０は左右方向に移動する。結局、移動装置１４１の移動量は、固定板１４１ｃの結合溝１４１ａの水平長さによって決定されるが、その移動量に合わせて支持部材１１０の水平部１１２の結合溝１１２ａの長さを設計し、連結部材１３０の締結孔１３１の間隔を調整する必要がある。 The connecting member 130 of the PC beam bridge temporary bracket 100 is inserted into the horizontal portion 112 of the pair of support members 110 above the PC beam 2 of the completed pier 1. Thereafter, the fixing rod 141d of the moving device 141 is inserted into a predetermined position where the fastening hole 131 of the connecting member 130 and the coupling groove 112a of the horizontal portion 112 of the support member 110 are aligned, and the moving device 141 is fixed. Connection and fastening are completed by inserting the fixing pin 141b into a predetermined position where the coupling hole 121 of the frame 120 and the coupling groove 141a of the fixing plate 141c are aligned. At this time, the insertion position of the fixing rod 141d of the moving device 141 is determined in consideration of an appropriate distance between the PC beams 2, and is inserted into the coupling hole 121 of the stationary frame 120 and the coupling groove 141a of the stationary plate 141c. The fixing pin 141b is fastened with a margin enough to move in the vertical direction along the coupling groove 141a of the fixing plate 141c. After all, as shown in FIGS. 1 and 2, with the moving device 141 raised, the fixing pin 141b of the fixing frame 120 is located at the lower end of the coupling groove 141a of the fixing plate 141c, and the moving device 141 is By lowering, the coupling groove 141a of the fixing plate 141c moves in the lower diagonal direction with respect to the fixing pin 141b, thereby moving the pair of support members 110 in the left-right direction. After all, the amount of movement of the moving device 141 is determined by the horizontal length of the coupling groove 141a of the fixed plate 141c. The length of the coupling groove 112a of the horizontal portion 112 of the support member 110 is designed according to the amount of movement. It is necessary to adjust the interval between the fastening holes 131 of the connecting member 130.

また、前述したように、組み立てられたＰＣ梁橋用仮設ブラケット１００を梁２に設置する場合、前記設置梁２の梁による施工上の問題解決と、上板が形成された既存橋梁の診断や維持補修を容易にするために、図１０に示すように、前記ＰＣ梁橋用仮設ブラケット１００の一対の支持部材１１０の垂直部１１１に連続して垂直連結部材１３０ａを設置する。前記ＰＣ梁橋用仮設ブラケット１００に垂直連結部材１３０ａを設置した後、垂直連結部材１３０ａの間に水平に置かれるパイプ部材を設置し、その上部に作業足場などを乗せることで、ガーター下部でのＰＣ梁橋用仮設ブラケット１００の設置及び解体を容易にする。前記垂直連結部材１３０ａの設置可否は、施工状況に合わせて決定する。 In addition, as described above, when the assembled temporary bracket 100 for a PC beam bridge is installed on the beam 2, it is possible to solve a problem in construction by using the beam of the installation beam 2 and to diagnose an existing bridge on which an upper plate is formed. In order to facilitate maintenance and repair, as shown in FIG. 10, a vertical connecting member 130 a is installed continuously to the vertical portion 111 of the pair of support members 110 of the temporary bracket 100 for PC beam bridge. After the vertical connecting member 130a is installed on the PC beam bridge temporary bracket 100, a horizontal pipe member is installed between the vertical connecting members 130a, and a work scaffold or the like is placed on the upper part of the pipe member. The installation and disassembly of the temporary bracket 100 for the PC beam bridge is facilitated. Whether or not the vertical connecting member 130a is installed is determined according to the construction situation.

その後、前記組み立てられた一対のＰＣ梁橋用仮設ブラケット１００を、前記固定板１４１ｃの連結孔１４１ｅに設置棒（図示せず）を挿入して両ＰＣ梁２間の間隔を見ながら、前記ＰＣ梁２の下部面まで斜めに下ろした後、前記ＰＣ梁２とＰＣ梁橋用仮設ブラケット１００が垂直を成すように支持部材１１０のガイド板１１１ａを利用して位置させる。この時、前記一対の支持部材１１０の垂直部１１１に形成されているガイド板１１１ａは、ＰＣ梁橋用仮設ブラケット１００が適正な位置に来るように誘導しながら接触面を増加させ、前記ＰＣ梁２との密着を強固にし、垂直部１１１の補強板の役割をする。すなわち、荷重が集中する垂直部と傾斜部の折曲部位に沿って前記ガイド板１１１ａが形成されることにより、ガイド板１１１ａが折曲部位を補強するようになる。 Thereafter, the PC brackets for the assembled pair of PC beam bridges 100 are inserted into the connecting holes 141e of the fixing plate 141c by inserting installation bars (not shown), and the intervals between the PC beams 2 are observed. After tilting down to the lower surface of the beam 2, the PC beam 2 and the PC beam bridge temporary bracket 100 are positioned using the guide plate 111a of the support member 110 so as to be vertical. At this time, the guide plate 111a formed on the vertical portion 111 of the pair of support members 110 increases the contact surface while guiding the temporary bracket 100 for the PC beam bridge to be in an appropriate position, and the PC beam 2 is strengthened, and serves as a reinforcing plate for the vertical portion 111. That is, by forming the guide plate 111a along the bent portion of the vertical portion and the inclined portion where the load is concentrated, the guide plate 111a reinforces the bent portion.

前記ＰＣ梁２フランジに支持部材の垂直部１１１の傾斜部が当接するように設置した後、前記固定板１４１ｃの連結孔１４１ｅに挿入された設置棒（図示せず）を上下方向に動かしたり、連結部材１３０を持ち上げたり、振ったりしながら自重を有する前記固定板１４１ｃの重さが移動装置１４１に伝わるようにして前記ＰＣ梁橋用仮設ブラケット１００がＰＣ梁２に密着するようにする。また、前述したように、締結された一対の支持部材１００の連結部材１３０上に荷重がかかったり、作業者が通行するようになって震動が発生すると、前記移動装置１４１は重力によって前記ＰＣ梁２により堅固に締結される。 After installing the PC beam 2 flange so that the inclined portion of the vertical portion 111 of the support member abuts, an installation bar (not shown) inserted into the connection hole 141e of the fixing plate 141c is moved up and down, The temporary bracket 100 for the PC beam bridge is brought into close contact with the PC beam 2 so that the weight of the fixing plate 141c having its own weight is transmitted to the moving device 141 while lifting or shaking the connecting member 130. In addition, as described above, when a load is applied to the connecting member 130 of the pair of fastened support members 100 or a vibration occurs due to the passage of an operator, the moving device 141 causes the PC beam to be moved by gravity. 2 is firmly fastened.

A fixing plate 141c 'in which a coupling hole (not shown) is perforated so that the coupling hole 122 is coupled to the coupling hole via the fixing pin 141b. Even when using a modified flag-shaped moving device 141 ′ composed of 120a, the construction is performed in the same manner as described above.

前記旗形移動装置１４１の代わりにＹ字形移動装置１４４または直線形移動装置１４５を用いる場合にも、前記支持部材１１０の結合溝１１２ａと連結部材１３０の締結孔１３１とが整合される所定の位置に挿入される固定バー１４４ｃ、１４５ａの連結孔１４４ｄ、１４５ｂに設置棒（図示せず）を挿入して、前述した旗形移動装置１４１の同様に、前記設置棒（図示せず）を上下方向に動かしながら前記固定バー１４４ｃ、１４５ａを前記Ｙ字形移動装置１４４の固定枠１４４ａの切欠部１４４ｂまたは直線形移動装置１４５の連結棒（１４５ｄ）に沿って移動させることにより、前記一対の支持部材１１０を左右方向に移動させる。この時、前記Ｙ字形移動装置１４４は、設置棒（図示せず）を前記固定枠１４４ａの貫通孔１４４ｇに挿入して施工することもできる。以下、他の施工方法は、前記旗形移動装置１４１の施工方法と同一である。 Even when a Y-shaped moving device 144 or a linear moving device 145 is used instead of the flag-shaped moving device 141, a predetermined position where the coupling groove 112a of the support member 110 and the fastening hole 131 of the connecting member 130 are aligned.
