We made and installed on the spot materials such as steel girders according to the main girder spacing and main girder height. However, in recent years, due to requests for rationalization of construction work for roads and bridges and cost reduction, a small number of main girder bridges will be constructed and planned with a wider space between the main girders and a smaller number of bridges than in the past. Since it was necessary to adapt to this small number of main girder bridges, and also to accommodate different main girder spacings and main girder heights in order to reuse the support work, the length of the girder was increased. Supporting work that allows the height of the pods to be variable is being used.

14 A rubber material 21 having a substantially hemispherical shape is attached to the lower end. Since the rubber material 21 has a substantially hemispherical shape, the center axis L of the column 14 is prevented from deviating from the line of action of the axial force (compressive load) applied to the column 14, which is indicated by the arrow in the figure. The columns 14 can be installed on the main girder 11. Further, the frictional force of the rubber material 21 can prevent the column 14 from being displaced from the initial installation position on the main girder 11. The shape of the rubber material 21 may be a substantially conical shape or a substantially pyramidal shape.

It is installed between 1 and 11 '. Also, the first beam member 12, 1
A bolt hole 51 is provided in the end surface of 2'on the side facing the main girders 11 and 11 ', and a bolt 52 is inserted into the bolt hole 51. The length of the bolt 52 protruding from the first beam member 12 (12 ') is adjusted and fixed by a nut 53.

Should be in contact with 11 (11 '). As shown in FIG. 10 (a), this is because the first beam members 12 and 12 ′ and the second beam member 13 are installed when the support structure 50 is installed at an inclination.
In addition to the own weight of these beam members, a horizontal component force of the load generated by the weight of the concrete floor slab or the like placed thereon is applied. This horizontal component force causes a horizontal shift (rightward in the figure) in the support work. Therefore, the bolt 52 projecting from the end face of the first beam member is always brought into contact with the main girder 11 to restrain the horizontal displacement of the support structure 50 in the horizontal direction and prevent the displacement.
