Description

A bending moment transfer separating device having an anti-falling device and a device for preventing bending moment transfer and a Rahmen Bridge using thereof,

The present invention relates to a bending moment transfer separating apparatus having a lower structure attached to a lower end of a wall of a Rahmen bridge (Rigid-frame Bridge) and having an overhang preventing device for reducing a bending moment transmitted from the upper structure to a foundation, More specifically, it is possible to prevent the conduction of the wall reinforcing bars and walls in the construction step, thereby securing the safety of the construction, and to prevent the local damage at the bottom of the wall in the use stage, To a bending moment transfer separating device equipped with a break preventing device capable of minimizing the work and a raymen bridge using the same.

In general, raymen bridge has a problem that the base is enlarged due to the member forces (axial force, shear force, and bending moment) acting on the upper structure and the wall are transmitted to the foundation by connecting the bottom of the wall and the foundation to the reinforced concrete, When the height is low, the ductility of the wall is insufficient, so that the member force transmitted to the foundation becomes so large that the base section can not be designed.

In recent years, an integral type bridge having maximized ductility of the lower structure has been introduced in Korea and is actively under construction. Also, by separating the reinforcing concrete which is the main material connecting the bottom of the wall and the foundation, the behavior similar to the hinge device is induced, A ramen bridge (hereinafter referred to as a hinge railway bridge) was developed and applied to reduce the size of the foundation without transmitting the moment on a basis.

However, such a hinge railway bridge has advantages such as economical efficiency and shortening of the air through the reduction of the base size, but has a problem of lacking safety in terms of construction. For example, in the case of a hinge ramen bridge in which both the wall and the foundation are made of precast, the wall is likely to be damaged before the upper structure is integrated with the wall, and the corner of the lower end of the wall hits the upper surface due to the rotational displacement of the common middle wall, A strong stress concentration is generated at the lower edge portion, so that breakage easily occurs.

In addition, in the case of the hinged ramen bridge manufactured on site, there is no lateral support point when the wall reinforcement is laid on the foundation, so that the wall reinforcement may be individually conducted or the entire reinforcing bar wall may be turned over. In the case of the rigid-frame raymen bridge, a part of the wall reinforcement is embedded on the foundation first, and the reinforcement of the wall is fixed by the binding wire to prevent the conduction. However, in the case of the hinged ramen bridge, There is a problem that it becomes rather cumbersome.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view showing a member force acting on a foundation and a corresponding wall reinforcing bar and a foundation reinforcing bar in a general fixed-end framing.

1, the foundation 6 of the fixed-end ramen bridge has a function of acting on the upper structure 4 in addition to the self weight, live load and earth pressure acting on the upper structure 4 and the wall 5, There is a problem in that the size of the foundation 6 is increased and the amount of the reinforcing bars 51 and 61 in the wall 5 and the foundation 6 is increased considerably due to temperature change, drying shrinkage, Therefore, by reducing the size of the foundation, it is possible to separate the reinforcing concrete, which is the main material connecting the wall 5 with the foundation, to induce a behavior similar to that of the hinge device, thereby preventing the bending moment of the member from being transmitted to the foundation 6, A hinge railway bridge capable of reducing the size of the bridge is being developed.

FIG. 2A is a view showing the conduction of the wall during the construction before the wall and the upper structure are integrated in the existing precast hinge railway bridges. FIG. Fig.

Hingeramen Bridge has advantages such as economical efficiency and shortening of air through reduction of base (6) size, but it has a problem that it lacks safety in terms of construction.

2a and 2b, the precast hinge rail bridge has no means to prevent conduction of the wall 5 before the upper structure 4 is integrated with the wall 5, Conduction accidents and breakage can not be avoided because there is no apparatus for dispersing the stress concentrated on the bottom concrete edge portion by the wall 5 and preventing edge cracking.

FIG. 3A is a view showing a conduction of a wall reinforcing bar during construction in a conventional field-made hinge railway bridge, and FIG. 3B is a diagram showing the overall conduction of a wall reinforcing bar.

3A and 3B, there is no means for preventing conduction of the wall reinforcing bars 51 when building the wall reinforcing bar 51. In order to overcome this problem, (6) Two minimum supporting points for welding the wall reinforcing bar 51 welded to the wall supporting pressure reinforcing bar 72 welded to the upper reinforcing bearing 71 and welded to the base upper reinforcing bearing 71 Should be secured. The welding tying means is required to dispose the wall supporting pressure reinforcing bars 72 more than necessary in accordance with the interval of the wall reinforcing bars 51 arranged closely to the cast iron rods. When the adjustment is required by the spacing and the coating error of the wall reinforcing bars 51, There is a problem of cutting and reworking. Since there is no inclined support, welding is possible only for rotation resistance. Therefore, unnecessary welders and welding equipment need to be installed for installing the wall reinforcing bar (51). It is impossible to solve the problem that the wall reinforcing bars 51 are simultaneously conducted together with the base upper reinforcing support 71, despite the welding of the wall reinforcing bars 51. [

As a technology to be a background of the present invention, there is a patent registration No. 1314081 entitled " Method for connecting both wall portions of a raymen structure and a top plate "(Patent Document 1). In the background art, (a) a two-wall portion formed with an outer finishing plate in the form of a vertical wall extending upward from an outer upper surface or an outer side surface is provided on a bottom plate, (b) a right wall formed by mounting an upper plate between the inner upper surfaces of the wall portions A U-shaped annular reinforcing bar extending from the upper surface of the wall part and the upper surface of the upper part is connected to the reinforcing bars of the U-shaped part by longitudinal reinforcing bars in the corner part, and (c) concrete is inserted into the U- And the spherical concave groove is formed at the center of the upper surface and the horizontal top surface portion is formed around the spherical concave groove so that the spherical concave portion of the concrete spherical concave portion, A bottom plate having a groove and a horizontal upper surface portion exposed to the upper surface is provided, and the bottom plate is inserted into the spherical concave groove to be rotatable The concrete spherical convex portion of the concrete block formed on the bottom surface of the spherical convex portion to be connected is disposed so as to be inserted into the spherical concave groove of the concrete spherical concave portion so that the concrete spherical convex portion is positioned at the lower end portion of the upper portion of the wall to construct the wall portion Wherein the concrete spherical convex portion is manufactured by using a preformed concrete spherical concave portion as a match-casting formwork, and a method of connecting both walls and a top plate of the rheme structure.

However, the above-mentioned background art also has no means to prevent the wall from falling before the upper structure is integrated with the wall, and there is no means to disperse the stress concentrated on the edge of the concrete at the bottom of the wall by rotation of the wall, There is a problem that conduction accident and breakage can not be avoided.
