As an example of the railway temporary work girder, one described in Patent Document 1 is known. As shown in FIGS. 1, 2, and 16 to 19, the temporary construction girder for railroad has a pair of left and right truss girders 1 and 1 as main structures arranged in parallel, and the lower part of these truss girders 1 and 1 A horizontal beam 2 is installed between the side beams 1a and 1a, a plurality of the horizontal beams 2 are arranged at predetermined intervals in the longitudinal direction of the truss beam 1, and the adjacent horizontal beams 2 and 2 are connected by the vertical beams 3 and 3.

When joining the abdomen 3a of the string 3 to the second joining plate 10b, the notch 3 This is to allow a part of the upper flange to escape so as not to interfere with the second bonding plate 10b. Further, a cutout portion 14 is formed on the upper flange of the end portion of the stringer 3 by cutting out substantially half of the width direction in a rectangular shape. The cutout portion 14 allows the stringer to be connected to the second joining plate 10b. When the three abdominal portions 3a are joined, the upper flange of the stringer 3 does not interfere with the second joining plate 10b.

また、切欠部１３は、第１接合板１０ｂの下側の角部を三角形状に切り欠いてなるものであり、第２接合板１０ｂに縦桁３の腹部３ａを接合する際に、該縦桁３の下フランジの一部が第２接合板１０ｂに干渉しないように逃がすためのものである。また、縦桁３の端部の下フランジには、その幅方向略半分を矩形状に切り欠いてなる切欠部１４が形成されており、この切欠部１４によって、第２接合板１０ｂに縦桁３の腹部３ａを接合する際に、該縦桁３の下フランジが第２接合板１０ｂに干渉しないようになっている。   The notch 13 is formed by notching the lower corner of the first joining plate 10b in a triangular shape, and when joining the abdomen 3a of the string 3 to the second joining plate 10b, A part of the lower flange of the girder 3 is used for escape so as not to interfere with the second joining plate 10b. Further, the lower flange of the end portion of the stringer 3 is formed with a notch 14 formed by cutting substantially half of the width direction into a rectangular shape. The notch 14 allows the stringer to be connected to the second joining plate 10b. When the three abdominal portions 3a are joined, the lower flange of the stringer 3 does not interfere with the second joining plate 10b.

また、第２接合板１０ｂには、切欠部１２，１３間において、上下左右に離間して合計４つの第２ボルト孔１５ａが形成されている。これら４つの第２ボルト孔１５ａは、第２接合板１０ｂの高さ方向中央部に対して対称的に配置されているのではなく、第２接合板１０ｂの下端側に若干寄せて配置されている。
前記上板１０ｃは矩形板状のものであり、２つの第３ボルト孔１６ａ，１６ａが離間して形成されている。 In addition, a total of four second bolt holes 15a are formed in the second joining plate 10b so as to be spaced apart from each other between the notches 12 and 13 in the vertical and horizontal directions. These four second bolt holes 15a are not arranged symmetrically with respect to the central portion in the height direction of the second joining plate 10b, but are arranged slightly closer to the lower end side of the second joining plate 10b. Yes.
The upper plate 10c has a rectangular plate shape, and two third bolt holes 16a and 16a are formed apart from each other.

前記連結ブラケット１０は、横桁２の長手方向における位置を調整可能に、横桁２にボルト接合されている。
すなわち、横桁２の腹部２ａには、図５〜図７に示すように、縦桁３の端部を接合すべき部位に、第１ボルト孔１１ｂが上下に所定間隔で複数個（４個）、横方向（横桁２の長手方向）に所定間隔で複数個形成されている。第１ボルト孔１１ｂの上下方向の個数とピッチは、前記連結ブラケット１０の第１接合板１０ａに形成された第１ボルト孔１１ａの上下方向の個数とピッチに等しくなっており、第１ボルト孔１１ｂの左右のピッチは、前記第１接合板１０ａに形成された第１ボルト孔１１ａの左右のピッチの半分と等しくなっている。
したがって、連結ブラケット１０の第１接合板１０ａを横桁２の腹部２ａに当接し、この第１接合板１０ａに形成されている縦二列の第１ボルト孔１１ａを、横桁２の腹部２ａに形成されている所望の縦二列の第１ボルト孔１１ｂに合致させて、合致した第１ボルト孔１１ａ，１１ｂにボルト１８を挿入してナット１８ａを螺合して締め付けることによって、連結ブラケット１０は、横桁２の長手方向における位置を調整可能に、横桁２にボルト接合されている。 The connecting bracket 10 is bolted to the cross beam 2 so that the position of the cross beam 2 in the longitudinal direction can be adjusted.
That is, as shown in FIGS. 5 to 7, the abdomen 2 a of the cross beam 2 has a plurality of (four) first bolt holes 11 b at a predetermined interval at the portion where the end of the vertical beam 3 is to be joined. ), A plurality are formed at predetermined intervals in the horizontal direction (longitudinal direction of the horizontal beam 2). The number and pitch of the first bolt holes 11b in the vertical direction are equal to the number and pitch of the first bolt holes 11a formed in the first joint plate 10a of the connection bracket 10 in the vertical direction. The left and right pitch of 11b is equal to half the left and right pitch of the first bolt holes 11a formed in the first joining plate 10a.
Therefore, the first joint plate 10a of the connecting bracket 10 is brought into contact with the abdomen 2a of the cross beam 2, and the first two bolt holes 11a formed in the first joint plate 10a are connected to the abdomen 2a of the cross beam 2. The connecting bracket is formed by fitting the bolts 18 into the first bolt holes 11a, 11b that match the desired vertical two rows of the first bolt holes 11b formed in the bolt, and screwing and tightening the nuts 18a. 10 is bolted to the cross beam 2 so that the position of the cross beam 2 in the longitudinal direction can be adjusted.

なお、本例では、第１接合板１０ａに第１ボルト孔１１ａを縦二列形成したが、縦一列でもよく、三列以上でもよい。また、横桁２の腹部２ａに形成する第１ボルト孔１１ｂの左右のピッチは、第１接合板１０ａに形成された第１ボルト孔１１ａの左右のピッチの整数分の１であればよい。
また、連結ブラケット１０の上板１０ｃは横桁２の上フランジの下面に当接されるとともに、上板１０ｃに形成された第３ボルト孔１６ａ，１６ａを、横桁２の上フランジに形成された第３ボルト孔１６ｂ，１６ｂに合致させて、合致した第３ボルト孔１６ａ，１６ｂにボルト１８を挿入してナット１８ａを螺合して締め付けることによって、上フランジにボルト接合されている。なお、連結ブラケット１０ｃの上板１０ｃを横桁２の上フランジに接合するのは、連結ブラケット１０が横桁２の長手方向における標準位置（例えば連結ブラケット１０を横桁２の長手方向と直交する方向で一直線上に配置する場合の位置）にある場合であり、連結ブラケット１０の横桁２の長手方向における位置を調整した場合等は、連結ブラケット１０ｃの上板１０ｃを横桁２の上フランジにボルト接合しない。 In this example, the first bolt holes 11a are formed in two vertical rows in the first joint plate 10a, but may be one vertical row or three or more rows. Moreover, the left-right pitch of the 1st bolt hole 11b formed in the belly part 2a of the cross beam 2 should just be 1 / integer of the left-right pitch of the 1st bolt hole 11a formed in the 1st joining board 10a.
The upper plate 10c of the connection bracket 10 is in contact with the lower surface of the upper flange of the cross beam 2 and the third bolt holes 16a, 16a formed in the upper plate 10c are formed in the upper flange of the cross beam 2. The bolts are joined to the upper flanges by fitting the third bolt holes 16b, 16b, inserting the bolts 18 into the matched third bolt holes 16a, 16b, and screwing and tightening the nuts 18a. The upper plate 10c of the connection bracket 10c is joined to the upper flange of the cross beam 2 because the connection bracket 10 is in a standard position in the longitudinal direction of the cross beam 2 (for example, the connection bracket 10 is orthogonal to the longitudinal direction of the cross beam 2). When the position of the connecting bracket 10 in the longitudinal direction of the cross beam 2 is adjusted, the upper plate 10c of the connecting bracket 10c is connected to the upper flange of the cross beam 2. Do not bolt on.

前記縦桁３は、上下方向における位置を調整可能に、連結ブラケット１０にボルト接合されている。
すなわち、縦桁３の端部の腹部３ａには、第２ボルト孔１５ｂが上下左右に離間して合計４つ形成されている。第２ボルト１５ｂの上下左右のピッチは、連結ブラケット１０の第２接合板１０ｂに形成されている第２ボルト孔１５ａの上下左右のピッチと等しくなっている。
そして、図９に示すように、連結ブラケット１０を上下反転して横桁２の腹部２ａにボルト接合することによって、４個の第２ボルト孔１５ａの上下の位置が異なるので、連結ブラケット１０の第２接合板１０ｂに縦桁３の腹部３ａを当接し、該腹部３ａに形成されている４個の第２ボルト孔１５ｂを、第２接合板１０ｂに形成されている４個の第２ボルト孔１５ａに合致させて、合致した第２ボルト孔１５ａ，１５ｂにボルト１８を挿入してナット１８ａを螺合して締め付けることによって、縦桁３は、上下方向における位置を調整可能に、連結ブラケット１０にボルト接合されている。つまり、図９（ａ）に示すように、連結ブラケット１０の上板１０ｃを上にして該連結ブラケット１０を横桁２に接合することによって、縦桁３は連結ブラケット１０の第２接合板１０ｂの下部に接合され、図９（ｂ）に示すように、連結ブラケット１０の上板１０ｃを下にして該連結ブラケット１０を横桁２に接合することによって、縦桁３は連結ブラケット１０の第２接合板１０ｂの上部に接合される。これによって、縦桁３の上下の位置が調整される。 The stringer 3 is bolted to the connection bracket 10 so that the position in the vertical direction can be adjusted.
That is, a total of four second bolt holes 15b are formed in the abdomen 3a at the end of the stringer 3 so as to be separated from each other vertically and horizontally. The vertical and horizontal pitches of the second bolts 15 b are equal to the vertical and horizontal pitches of the second bolt holes 15 a formed in the second joining plate 10 b of the connection bracket 10.
Then, as shown in FIG. 9, the upper and lower positions of the four second bolt holes 15 a are different by flipping the connecting bracket 10 upside down and bolting it to the abdomen 2 a of the cross beam 2. The abdomen 3a of the string 3 is brought into contact with the second joint plate 10b, and the four second bolt holes 15b formed in the abdomen 3a are replaced with four second bolts formed in the second joint plate 10b. The stringer 3 can be adjusted in the vertical direction by inserting the bolt 18 into the matched second bolt holes 15a, 15b and screwing and tightening the nut 18a to match the hole 15a. 10 is bolted. That is, as shown in FIG. 9A, by connecting the connecting bracket 10 to the cross beam 2 with the upper plate 10 c of the connecting bracket 10 facing up, the vertical beam 3 becomes the second connecting plate 10 b of the connecting bracket 10. As shown in FIG. 9 (b), the vertical bracket 3 is connected to the cross beam 2 by connecting the connection bracket 10 to the horizontal beam 2 with the upper plate 10 c of the connection bracket 10 facing down. It joins to the upper part of 2 joining board 10b. Thereby, the vertical position of the vertical beam 3 is adjusted.

なお、縦桁３をその上下方向における位置を調整可能に、連結ブラケット１０にボルト接合する場合、以下のようにしてもよい。
すなわち、連結ブラケット１０の第２接合板１０ｂに上下に所定間隔で複数の第２ボルト孔を形成しておき、所望の第２ボルト孔にボルトを挿通して縦桁３をボルト接合することによって、縦桁３の上下方方向における位置を調整可能としてもよい。この場合、第２接合板１０ｂに形成する第２ボルト孔の上下のピッチを、縦桁３の腹部３ａに形成する第２ボルト孔の上下のピッチの整数分の１とすればよい。 When the stringer 3 is bolted to the connecting bracket 10 so that the position in the vertical direction can be adjusted, the following may be performed.
That is, by forming a plurality of second bolt holes at predetermined intervals in the second joint plate 10b of the connecting bracket 10 and inserting the bolts into the desired second bolt holes, The position in the upper and lower direction of the string 3 may be adjustable. In this case, the upper and lower pitches of the second bolt holes formed in the second joining plate 10b may be set to an integral number of the upper and lower pitches of the second bolt holes formed in the abdomen 3a of the stringer 3.

また、縦桁３の上下の位置を調整可能とする場合、横桁２に対する連結ブラケット１０の上下の取付位置を調整可能としてもよい。例えば、横桁２の上下の高さが高い場合等に、第１ボルト孔１１ｂを上下に所定ピッチで、５個以上形成しておき、連結ブラケット１０の第１接合板１０ａを横桁２の腹部２ａに当接し、第１接合板１０ａに形成された第１ボルト孔１１ａを、横桁２の腹部２ａに形成された所望の第１ボルト孔１１ｂに合致させて、合致した第１ボルト孔１１ａ，１１ｂにボルト１８を挿入してナット１８ａを螺合して締め付けることによって、横桁２に対する連結ブラケット１０の上下の取付位置を調整可能としてもよい。   When the vertical position of the vertical beam 3 can be adjusted, the vertical mounting position of the connection bracket 10 with respect to the horizontal beam 2 may be adjustable. For example, when the vertical height of the cross beam 2 is high, five or more first bolt holes 11b are formed at a predetermined pitch in the vertical direction, and the first joining plate 10a of the connection bracket 10 is The first bolt hole 11a which is in contact with the abdomen 2a and matches the desired first bolt hole 11b formed in the abdomen 2a of the cross beam 2 with the first bolt hole 11a formed in the first joint plate 10a. The upper and lower mounting positions of the connecting bracket 10 with respect to the cross beam 2 may be adjustable by inserting bolts 18 into 11a and 11b and screwing and tightening the nuts 18a.

また、本実施の形態では、図１０に示すように、縦桁３と連結ブラケット１０との間に、この連結ブラケット１０に対する縦桁３の横桁２の長手方向における位置を調整する調整部材２０が介在している。
すなわち、縦桁３の腹部３ａと連結ブラケット１０の第２接合板１０ｂとは、ボルト１８およびナット１８ａによってボルト接合されおり、このボルト１８の周囲において、縦桁３の腹部３ａと連結ブラケット１０の第２接合板１０ｂとの間に、ナット状に形成された調整部材２０が介在している。
調整部材２０はその厚さに応じて複数種類あり、所望の厚さの調整部材２０を縦桁３の腹部３ａと連結ブラケット１０の第２接合板１０ｂとの間に介在させることによって、連結ブラケット１０に対する縦桁３の横桁２の長手方向における位置を微調整できる。
つまり、横桁２の長手方向における縦桁３の位置は、横桁２に対する連結ブラケット１０の取付位置で調整可能であるが、調整部材２０の厚さを、横桁２の腹部２ａに形成された第１ボルト孔１１ｂの横方向のピッチより小さく設定することによって、縦桁３の取付位置を第１ボルト孔１１ｂのピッチより小さい範囲で微調整できる。 Further, in the present embodiment, as shown in FIG. 10, the adjustment member 20 that adjusts the position in the longitudinal direction of the cross beam 2 of the vertical beam 3 relative to the connection bracket 10 between the vertical beam 3 and the connection bracket 10. Is intervening.
That is, the abdomen 3 a of the stringer 3 and the second joint plate 10 b of the connection bracket 10 are bolted by the bolt 18 and the nut 18 a, and the abdomen 3 a of the stringer 3 and the connection bracket 10 are surrounded by the bolt 18. An adjusting member 20 formed in a nut shape is interposed between the second joining plate 10b.
There are a plurality of types of adjusting members 20 depending on the thickness of the adjusting member 20, and the connecting member 20 having a desired thickness is interposed between the abdomen 3a of the string 3 and the second joining plate 10b of the connecting bracket 10, thereby connecting brackets. The position in the longitudinal direction of the horizontal beam 2 of the vertical beam 3 with respect to 10 can be finely adjusted.
That is, the position of the vertical beam 3 in the longitudinal direction of the cross beam 2 can be adjusted by the mounting position of the connecting bracket 10 with respect to the horizontal beam 2, but the thickness of the adjustment member 20 is formed in the abdomen 2 a of the horizontal beam 2. By setting the pitch smaller than the horizontal pitch of the first bolt holes 11b, the attachment position of the stringer 3 can be finely adjusted within a range smaller than the pitch of the first bolt holes 11b.

次に、上記構成の鉄道用仮設工事桁の組立て方法について説明する。
まず、工事を行うべき地盤に設置されている枕木４とレール５を一時撤去する。
次に、工事を行うべき地盤の横で、本発明に係る鉄道用仮設工事桁を以下のようにして組み立てる。まず、トラス桁１，１を所定間隔で平行に地盤に配置し、このトラス桁１，１の下部側桁１ａ，１ａ間に横桁２を架設し、この横桁２の両端部をそれぞれトラス桁１，１にボルト接合によって接合する。横桁２はトラス桁１の長手方向に所定間隔で配置するが、配置する横桁２のピッチは地盤に設置されていた枕木４のピッチより長くする。例えば、本実施の形態では、隣り合う横桁２，２間に、５本の枕木４を配置できるように、横桁２のピッチを設定する。 Next, a method for assembling the railway temporary construction girder having the above-described configuration will be described.
First, the sleepers 4 and the rails 5 installed on the ground to be constructed are temporarily removed.
Next, the temporary construction girder for railroad according to the present invention is assembled as follows on the side of the ground to be constructed. First, truss girders 1 and 1 are arranged on the ground in parallel at a predetermined interval, a horizontal girder 2 is installed between the lower side girders 1a and 1a of the truss girder 1 and 1, and both ends of the horizontal girder 2 are respectively attached to the truss. Join the girders 1 and 1 by bolting. The cross beams 2 are arranged at predetermined intervals in the longitudinal direction of the truss girder 1, but the pitch of the cross beams 2 to be arranged is longer than the pitch of the sleepers 4 installed on the ground. For example, in the present embodiment, the pitch of the cross beam 2 is set so that five sleepers 4 can be arranged between the adjacent cross beams 2 and 2.

次に、隣り合う横桁２，２間に縦桁３，３を配置し、この縦桁３，３の端部を横桁２の腹部２ａに連結ブラケット１０によって取り付ける。これによって、隣り合う横桁２，２を縦桁３，３によって連結する。
縦桁３，３の端部を横桁２の腹部２ａに連結ブラケット１０によって取り付ける場合、連結ブラケット１０の第１接合板１０ａを横桁２の腹部２ａに当接するとともに、連結ブラケット１０の横桁２の長手方向における位置を調整する。この調整は連結ブラケット１０の第１接合板１０ａを左右にスライドさせて所望の位置に位置させ、第１接合板１０ａに形成されている縦二列の第１ボルト孔１１ａを、横桁２の腹部２ａに形成された所望の縦二列の第１ボルト孔１１ｂに合致させて、合致した第１ボルト孔１１ａ，１１ｂにボルト１８を挿入してナット１８ａを螺合して締め付けることによって行う。このようにして、連結ブラケット１０を、横桁２の腹部２ａに該横桁２の長手方向における位置を調整して取り付ける。
なお、連結ブラケット１０は全ての横桁２の腹部２ａに取り付けるが、一つの横桁２の腹部２ａを挟んで対称的に配置される連結ブラケット１０，１０は、それらの第１接合板１０ａ，１０ａにそれぞれ形成されている縦二列の第１ボルト孔１１ａ，１１ａを、横桁２の腹部に形成された所望の縦二列の第１ボルト孔１１ｂに合致させて、合致した第１ボルト孔１１ａ，１１ｂにボルト１８を挿入してナット１８ａを螺合して締め付けることによって行う。 Next, the vertical beams 3 and 3 are arranged between the adjacent horizontal beams 2 and 2, and the ends of the vertical beams 3 and 3 are attached to the abdomen 2 a of the horizontal beam 2 by the connecting bracket 10. As a result, the adjacent horizontal beams 2 and 2 are connected by the vertical beams 3 and 3.
When attaching the end portions of the vertical beams 3 and 3 to the abdominal portion 2a of the horizontal beam 2 with the connecting bracket 10, the first joining plate 10a of the connecting bracket 10 abuts against the abdominal portion 2a of the horizontal beam 2 and the horizontal beam of the connecting bracket 10 The position in the longitudinal direction of 2 is adjusted. In this adjustment, the first joint plate 10a of the connecting bracket 10 is slid to the left and right to be positioned at a desired position, and the two vertical rows of first bolt holes 11a formed in the first joint plate 10a The bolts 18 are inserted into the matched first bolt holes 11a and 11b, and the nuts 18a are screwed together and tightened so as to match the desired vertical two rows of first bolt holes 11b formed in the abdomen 2a. In this way, the connecting bracket 10 is attached to the abdomen 2a of the cross beam 2 while adjusting the position of the cross beam 2 in the longitudinal direction.
The connecting brackets 10 are attached to all the abdominal portions 2a of the cross beams 2, but the connecting brackets 10 and 10 arranged symmetrically across the abdominal portion 2a of one cross beam 2 are connected to the first joining plates 10a, The first bolt holes 11a, 11a in the two vertical rows formed in 10a are matched with the desired first bolt holes 11b in the two vertical rows formed in the abdomen of the cross beam 2, and the matched first bolts The bolts 18 are inserted into the holes 11a and 11b, and the nuts 18a are screwed and tightened.

また、直線区間にレール５が配置される場合、連結ブラケット１０は、横桁２の長手方向と直交する方向において一直線上に配置するが、例えば、曲線区間にレール５が配置される場合、図１１に示すように、連結ブラケット１０を略曲線を描くようにして配置する。つまり、一つの横桁２を挟んで配置される連結ブラケット１０，１０を横桁２の長手方向に若干ずらして全体として略曲線を描くようにして配置する。   When the rail 5 is arranged in the straight section, the connecting bracket 10 is arranged on a straight line in the direction orthogonal to the longitudinal direction of the cross beam 2. For example, when the rail 5 is arranged in the curved section, FIG. As shown in FIG. 11, the connecting bracket 10 is arranged so as to draw a substantially curved line. That is, the connecting brackets 10, 10 arranged with one horizontal beam 2 sandwiched therebetween are slightly shifted in the longitudinal direction of the horizontal beam 2 so as to draw a substantially curved line as a whole.

上記のようにして横桁２の腹部２ａに連結ブラケット１０を取り付けた後、この連結ブラケット１０に縦桁３の端部を取り付ける。この場合、連結ブラケット１０の第２接合板１０ｂに縦桁３の腹部３ａを当接し、該腹部３ａに形成されている４個の第２ボルト孔１５ａを、第２接合板１０ｂに形成されている４個の第２ボルト孔１５ｂに合致させて、合致した第２ボルト孔１５ａ，１５ｂにボルト１８を挿入してナット１８ａを螺合して締め付けることによって行う。
また、直線区間にレール５が配置される場合、全ての縦桁３を、その上下方向の位置を等しくして配置するが、例えば、曲線区間にレール５が配置される場合、図１２に示すように、レールのカントに合せて、隣り合う縦桁３，３のうち一方を他方に比べて高く配置する。この場合、図９に示すように、連結ブラケット１０を上下反転して横桁２の腹部２ａにボルト接合することによって、４個の第２ボルト孔１５ａの上下の位置が異なるので、連結ブラケット１０の第２接合板１０ｂに縦桁３の腹部３ａを当接し、該腹部３ａに形成されている４個の第２ボルト孔１５ｂを、第２接合板１０ｂに形成されている４個の第２ボルト孔１５ａに合致させて、合致した第２ボルト孔１５ａ，１５ｂにボルト１８を挿入してナット１８ａを螺合して締め付けることによって、レールのカントに合せて、隣り合う縦桁３，３のうち一方を他方に比べて高く配置する。 After the connection bracket 10 is attached to the abdomen 2 a of the cross beam 2 as described above, the end of the vertical beam 3 is attached to the connection bracket 10. In this case, the abdomen 3a of the string 3 is brought into contact with the second joining plate 10b of the connecting bracket 10, and four second bolt holes 15a formed in the abdomen 3a are formed in the second joining plate 10b. The four second bolt holes 15b are matched, the bolts 18 are inserted into the matched second bolt holes 15a and 15b, and the nuts 18a are screwed and tightened.
Further, when the rail 5 is arranged in the straight section, all the vertical girders 3 are arranged with the same vertical position, but for example, when the rail 5 is arranged in the curved section, it is shown in FIG. As described above, one of the adjacent longitudinal girders 3 and 3 is arranged higher than the other in accordance with the cant of the rail. In this case, as shown in FIG. 9, the upper and lower positions of the four second bolt holes 15 a are different by turning the connecting bracket 10 upside down and bolting to the abdomen 2 a of the cross beam 2. The second abutting portion 3a of the string 3 is brought into contact with the second joining plate 10b, and the four second bolt holes 15b formed in the abdominal portion 3a are replaced by four second bolts formed in the second joining plate 10b. By matching the bolt holes 15a, inserting the bolts 18 into the matched second bolt holes 15a and 15b, and screwing and tightening the nuts 18a, the adjacent stringers 3 and 3 can be matched to the rail cant. One of them is arranged higher than the other.

また、連結ブラケット１０の、横桁２と直交する方向における位置を微調整する場合、第１０図に示すように、所望の厚さの調整部材２０を縦桁３の腹部と連結ブラケット１０の第２接合板１０ｂとの間に介在させることによって、連結ブラケット１０に対する縦桁３の横桁２の長手方向における位置を微調整できる。   When the position of the connecting bracket 10 in the direction orthogonal to the cross beam 2 is finely adjusted, as shown in FIG. 10, the adjustment member 20 having a desired thickness is connected to the abdomen of the vertical beam 3 and the connecting bracket 10 in the first position. By interposing between the two joining plates 10b, the position of the longitudinal beam 3 in the longitudinal direction of the longitudinal beam 3 with respect to the connecting bracket 10 can be finely adjusted.

上記のようにして、トラス桁１，１に横桁２を接合するとともに、隣り合う横桁２，２間に縦桁３，３を配置して、連結ブラケット１０によってボルト接合することによって鉄道用仮設工事桁を組み立てた後、この鉄道用仮設工事桁の縦桁３，３に、一時撤去した前記枕木４を架け渡すようにして設置するとともに縦桁３の長手方向に所定間隔で配置し、次いで、枕木４・・・にレール５，５を互いに平行に設置する。縦桁３，３の上下左右の位置は全て調整されているので、この縦桁３，３に枕木４・・・を介して設置されるレール５，５の上下左右の位置も調整されている。
このようにして、枕木４・・・とレール５，５とが設置された鉄道用仮設工事桁を、クレーン等によって吊り下げて、工事を行うべき地盤に設置する。この際、トラス桁１，１の両端部が工事を行うべき地盤に設けられた図示しない支持部によって支持される。したがって、レール５，５は工事を行うべき地盤上で鉄道用仮設工事桁によって支持されることになる。その後、横桁２，２の下方の地盤を掘削して、レール５，５の下方に該レール５，５を横断する構造物を構築する。このようにして、レール５，５の下方に構造物を構築できる。 As described above, the cross beam 2 is joined to the truss girders 1 and 1, and the vertical girders 3 and 3 are arranged between the adjacent cross girders 2 and 2, and are bolted by the connecting bracket 10. After assembling the temporary construction girders, the temporary bridges 3 and 3 of the railway temporary construction girders are installed so as to bridge the sleepers 4 that have been temporarily removed, and are arranged at predetermined intervals in the longitudinal direction of the vertical girders 3; Next, the rails 5 and 5 are installed on the sleepers 4. Since all the vertical and horizontal positions of the vertical girders 3 and 3 are adjusted, the vertical and horizontal positions of the rails 5 and 5 installed on the vertical girders 3 and 3 via the sleepers 4 are also adjusted. .
In this way, the railway temporary work girder in which the sleepers 4... And the rails 5 and 5 are installed is suspended by a crane or the like and installed on the ground on which construction is to be performed. At this time, both end portions of the truss girders 1 and 1 are supported by a support portion (not shown) provided on the ground to be constructed. Therefore, the rails 5 and 5 are supported by the temporary construction girder for railway on the ground on which construction is to be performed. Thereafter, the ground below the cross beams 2 and 2 is excavated to construct a structure that crosses the rails 5 and 5 below the rails 5 and 5. In this way, a structure can be constructed below the rails 5 and 5.

本実施の形態によれば、横桁２に縦桁３が連結ブラケット１０を介してボルト接合によって着脱可能に取り付けられているので、工事終了後に、横桁２から縦桁３を取り外すことによって、縦桁３および横桁２を再利用することができる。
