Definitions
- the present invention relates to a method for constructing a steel composite girder bridge, and more particularly, to maintain a non-synthetic cross section in the field-pouring bottom plate when prestress is introduced, and after the introduction of the prestress is completed by filling with a non-shrink mortar in the shear connector position to act as a synthetic cross section
- the present invention relates to a method for constructing a composite girder bridge.
- bridges are elevated structures made to cross over rivers, lakes, straits, bays, canals, lowlands or other traffic routes or structures, as shown in FIG. are divided into
- the superstructure 10 refers to a structure above the alternating 22 or pier 24 and is generally comprised of a girder 12, a slab 14.
- Determining the type of the bridge is determined according to the shape of the main member, usually the main member is a member that receives the most force, and the main member is a girder 12 is called a girder bridge, the slab 14 is a vehicle, etc. As the bottom plate to be carried, the concrete is poured into the bottom plate.
- the undercarriage 20 refers to alternating 22 and pier 24 which serve to safely transfer the load acting on the superstructure 10 to the ground.
- the shift 22 is a point at the beginning of the bridge, and the bridge 24 is an intermediate point other than the start point, and the type of foundation, pile foundation, well passage foundation, etc. is directly determined by the ground state under the bridge 24.
- the foundation slab 26 is located under the pier 24.
- the present invention has been made in order to solve the above problems, by maintaining the non-synthetic cross section in the field-pouring bottom plate when pre-stress is introduced, and after the introduction of the pre-stress is completed by filling the shear connector with non-shrink mortar to act as a synthetic cross section It is an object of the present invention to provide a method for constructing a composite girder bridge that can prevent an unfavorable stress state and improve economic efficiency of steel girders.
- Steel composite girder bridge construction method for achieving the above object is the step of installing a steel girders continuously formed so that the shear connection member is a predetermined distance apart from the pier;
- non-synthetic member is characterized in that any one of an adhesive sheet material, vinyl, tape, fiber material and grease.
- the prestress is characterized in that it is introduced when the concrete compressive strength of the point bottom plate section is 28MPa or more.
- the construction method is characterized in that it is applied to the rigid composite bridge of the opening type, spherical shape, plate girder and minority type.
- 1 is a structural diagram of a general girder bridge
- FIG. 2 is a flow chart of the girder bridge construction method according to an embodiment of the present invention
- Figure 2 is a flow chart of the girder bridge construction method according to an embodiment of the present invention
- Figures 3 to 17 is a detailed view of the process of Figure 2
- Figures 4 and 17 is L-shaped steel for reinforcing steel girder 31 Is a cross-sectional view where the support beam 50 is installed at predetermined intervals.
- the girder 31 is installed to the pier part 30 by crane work, and the shear connector 32 is spaced a predetermined distance from the top of the girder 31.
- S202 a continuous
- the first formwork 34 for placing the bottom plate concrete is installed on the floor, and the copper group 33 for supporting the first formwork 34 is reinforced.
- the first formwork 34 is not installed in the upper plate (31a) of the girder 31, the shear connector 32 is formed (S204).
- the portion of the girder 31, in which the first formwork 34 is not installed becomes a non-synthetic section a so that compressive stress does not occur in the girder 31 when prestress is introduced.
- a non-synthetic member 35 is installed on the upper flange 31 a of the girder 31 forming the point non-synthesis section a,
- the second formwork 36 is installed so that the concrete is not poured when the bottom plate concrete is poured in all around the upper flange 31a around the shear connector 32 (S206).
- the non-synthetic member 35 may be any material capable of securing non-synthesis such as adhesive sheet material, vinyl, tape, fiber material, and grease, and the non-synthetic section a is prestressed to the branch bottom plate 39. At the time of introduction, it becomes a section which induces a non-synthetic action of the girder upper flange 3a and the branch bottom plate 39.
- the reinforcing bar is assembled, and the point part is cast and cured in the state of placing the sheath pipe 37 and steel wire for prestress introduction.
- the bottom plate 39 is formed (S208).
- the sheath tube 37 is a tube which is placed in advance before the concrete is cast in order to make the placement hole of the prestressed steel (not shown) in the post tension method.
- the branch bottom plate 39 is not synthesized with the girder 31, and thus the compressive stress is applied to the girder 31 when the prestress is introduced. This will not happen.
- the base plate is made by assembling reinforcing bars between the pier part 30 and the pier part 30, that is, in the span part, and then curing them after pouring concrete. 41 is formed.
- non-shrink mortar 40 is filled in the front end pocket 38 of the branch portion to induce a synthesizing action between the girder 31 and the branch bottom plate 39 into which the prestress is introduced (S212).
- the bottom plate 42 of the entire girder bridge is formed by the point bottom plate 39 and the base plate bottom plate 41.
- the base plate 33 and the formwork 34 and 36 which are already installed, are dismantled, and the bottom plate 42 is paved with an appropriate cross-linking paving material to make the road 43 ), And the protective wall 44 is installed along both sides to complete the construction of the steel composite girder bridge (S214).
- the steel composite bridge types to which the construction methods of the girder bridges described above can be applied are open type, spherical, plate girder and minor column type.
