Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a girder supporting block of a bridge and a girder holding method using the same.
Generally, bridges include alternations located at the start and end points of a bridge, bridge (s) located between alternation and alternation, alternation and bridge, or tops connecting bridge and bridge. If the distance between shift and shift is short, the bridge is excluded. There is provided a stretch joint device for absorbing thermal deformation of the upper plate between the alternation and the upper plate, and a bridge support (also referred to as a bearing or a quasi-device) for supporting the upper plate between the alternation and the upper plate and between the bridge and the upper plate.
As an example of a method of constructing bridges, alternate construction is carried out at the starting point and the end point at which the bridges are installed, and the bridge (s) are constructed between the alternation and the alternation. After installing the bridge supports in the width direction of the bridges (the width direction of the upper bridge of the bridge) on the upper surface of the bridge and the piers, the girders are mounted at regular intervals in the width direction of the bridge between the bridge and the piers. The number of bridge supports installed on the top of each of the two shifts is equal to the number of girders, and the number of bridge supports installed on the bridge is twice the number of bridge supports installed on the bridge. That is, the bridge supports installed on the upper surface of the bridge pier are arranged in two rows, and the number of bridge supports arranged on one row is equal to the number of bridge supports installed on the bridge. When the girder is placed between the alternation and the pier, one end of the girder is mounted on the bridge support installed on the alternate and the other end of the girder is mounted on the bridge support installed on the bridge.
In addition, a girder is installed between the bridge and the pier and a girder is installed to construct the girder and the slab. The concrete is placed in the formwork and the concrete is placed in the formwork to construct the upper plate between the bridge and the bridge. An expansion joint device is installed between the upper plate and the upper plate.
However, in the conventional bridge as described above, since the bridge supports are installed at alternate and pier angles at the time of construction, one end of the girder is mounted on the alternate bridge support and the other end of the girder is mounted on the bridge support of the bridge. It is difficult to mount the girders in between, and there is a risk of the girder being turned over and it takes a long time to work. Also, since the bridge supports are arranged in two rows in order to support the girders at the bridge piers, not only the number of bridge supports is increased but also the operation time for installing the bridge supports is long.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a girder supporting block for a bridge which makes it possible to securely and fastly fasten a girder which is placed at alternate and pier angles, and a girder holding method using the same.
Another object of the present invention is to provide a girder supporting block of a bridge which reduces the number of bridge supports (bearings) provided on the upper portion of the bridge and the pier, and a method of mounting the girder of the bridge using the same.
In order to achieve the object of the present invention as described above, Placing a girder supporting block having an insertion space on the bridge supports; Mounting one end of the girders on the girder supporting block so as to be positioned in the insertion space of the girder supporting block; And placing the concrete in the insertion space of the girder supporting block.
The girder supporting block includes: a concrete body; A reinforcing structure provided inside the concrete body; And an insertion space formed in the concrete body and into which one of the girders is inserted, wherein the concrete body is a rectangular plate-shaped bottom plate; A vertical plate extending perpendicularly to one side of the lower plate; Side plates provided on both sides of the bottom plate and the vertical plate to close both sides; And spacing-maintaining blocks which are spaced apart from each other on the lower surface of the lower plate and which maintain the spacing of the girders.
The bridge supports are preferably arranged in a row.
It is preferable that the interval maintaining block is in the form of a rectangular plate having a uniform thickness.
And the spacing maintaining blocks are located on the same plane as one end face of the bottom plate of the concrete body.
Further, in order to achieve the object of the present invention, there is provided a method of manufacturing a bridge structure, Placing a girder supporting block having an insertion space on the bridge supports; Placing one end of the first girders on one side of the girder supporting block so as to be positioned in the insertion space of the girder supporting block; Placing one end of the second girders on the other side of the girder supporting block so as to be positioned in the insertion space of the girder supporting block; And placing the concrete in the insertion space of the girder supporting block.
The girder supporting block includes: a concrete body; A reinforcing structure provided inside the concrete body; And an insertion space formed on a front surface and an upper surface of the concrete body and into which the girders are inserted, wherein the concrete body is a rectangular plate-shaped bottom plate; Side plates extending at both side ends of the lower surface plate in a direction perpendicular to the lower surface plate; And spacing-maintaining blocks which are spaced apart from each other on the front and rear sides of the bottom plate to maintain the spacing of the girders.
Wherein the spacing maintaining blocks for supporting the first girders are located on the same plane as one end face of the bottom plate of the concrete body and the spacing maintaining blocks for supporting the second girders are located on the same plane as the other end face of the bottom plate of the concrete body .
Further, in order to achieve the object of the present invention, a concrete body; A reinforcing structure provided inside the concrete body; And an insertion space formed over the front surface and the upper surface of the concrete body and into which the girders are inserted, wherein the concrete body is a rectangular plate-shaped bottom plate; A vertical plate extending perpendicularly to one side of the lower plate; Side plates provided on both sides of the bottom plate and the vertical plate to close both sides; And spacing-maintaining blocks which are spaced apart from the bottom plate and which maintain the spacing of the girders.
Further, in order to achieve the object of the present invention, a concrete body; A reinforcing structure provided inside the concrete body; And an insertion space formed over the front and rear surfaces of the concrete body and into which the girders are inserted, wherein the concrete body is a rectangular plate-shaped bottom plate; Side plates extending at both side ends of the lower surface plate in a direction perpendicular to the lower surface plate; And spacing-maintaining blocks which are spaced apart from each other on the front and rear sides of the bottom plate to maintain the spacing of the girders.
In the present invention, since the bridge supports are installed at alternate or piers, the girder support block is placed on the shift bases and the girders are mounted at intervals set in the girder support block, so that the girders are not aligned with the bridge supports one by one, Is not only very safe but also shortens the working time.
Further, since the present invention does not arrange the bridge supports in a one-to-one correspondence with the number of the girders, the number of bridge supports is reduced, shortening the time for installing the bridge supports. Particularly, when the bridge supports are installed on the upper surface of the bridge pier, the number of bridge supports can be reduced by half compared with the conventional bridge supports, thereby shortening the time for installing the bridge supports and facilitating the maintenance of the bridge supports.
