Description

Technical Field [0001] The present invention relates to a reinforced concrete reinforced concrete structure,

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a reinforced concrete reinforced corrugated steel plate reinforcing structure, and more particularly, to a reinforced concrete reinforced corrugated steel plate reinforcing structure in which a corrugated steel plate having a crest portion and a valley portion of a corrugated steel plate is continuously joined along the longitudinal direction, Reinforced concrete structure reinforced with reinforced concrete reinforced concrete structure through upper horizontal reinforcing bars and lower reinforcing bars to increase the static force and prevent damage or deformation. .

Generally, the corrugated steel plate structure is a flexible structure, which is flexible and can be flexibly applied to unequal subsidence, so it is used for underground passages, water or ship culverts across roads and railways, Are widely used as bridges and aggregates across small streams, as water tanks, and as building materials for construction.

The corrugated steel pipe structure is a structure that is completed by assembling corrugated steel pipes. Therefore, the size and shape of the corrugated steel pipe can be variously used depending on the combination of corrugated steel sheets.

It is used for pipe-arch type, which has the most basic cross-section, and pipe-arch type, which has improved water-permeability. Other uses include elliptical type, underpass type, arch type, high profile arch type, low profile arch type, Pear Arch type and box- Various cross-sectional shapes can be used to suit the situation in the field.

In addition, it is possible to apply corrugated steel sheet to a larger structure by multi-span type cross section using reinforcement.

In such a corrugated steel plate structure, a fastening hole is formed in the corrugated steel plate so as to insert a fastening hole such as a bold, and a plurality of mountains and valleys are repeatedly formed to form a corrugation. At one side of the corrugated steel plate, The fastening hole is formed at a position spaced apart from the fastening hole, and the fastening hole is formed at a position which is less distant from the fastening hole formed in the mountain.

The other side of the corrugated steel sheet is formed with a fastening hole at a position spaced from the edge of the corrugated steel sheet by a predetermined distance at the corrugated portion in accordance with the position of the fastening hole on one side of the adjacent corrugated steel sheet for fastening with the corrugated steel sheet adjacent thereto, And a fastening hole is formed at a position that is less apart from the fastening hole.

The corrugated steel sheet structure is provided by continuously stacking the corrugated steel sheets below the adjacent corrugated steel sheets by bolting. Such a superposed structure has an advantage in that the corrugated steel sheet has excellent bending resistance.

However, the corrugated steel plate structure has a small contact area in the course of joining the corrugated steel plates to the lower portion of the adjacent corrugated steel sheets in the process of joining by the bolting, and the area overlapping with the bolting is sufficiently There is a problem that it can not be done.

In addition, there is a problem that the bolting operation is difficult and the sufficient rigidity can not be maintained.

And there was another problem that the safety was not sufficiently secured within this.

On the other hand, when the corrugated steel plate structure is small, a single bent steel plate is used. If the corrugated steel plate structure is large, the bending rate of the corrugated steel plate structure is increased.

The construction of the structure using the corrugated steel plate is performed by installing the corrugated steel plate so that the lower portion of the corrugated steel plate is perpendicular to the channel installed in the foundation ground, then repeating the bolting operation while the corrugated steel plates are overlapped with each other A structure made of a corrugated steel sheet can be obtained.

Such a corrugated steel plate structure is formed to have a shape in which wrinkles are continuously formed on a thin corrugated steel sheet. Therefore, when the length of the span is long, There was a cause of partial deformation.

In order to solve this problem, a reinforcing method and a reinforcing structure of a corrugated steel plate structure of the invention Patent No. 0698028 (registered on Mar. 15, 2007) have been proposed. The proposed reinforcing structure is anchored to the anchor bolt insertion groove of the corrugated steel sheet The anchor bolts are coupled with the reinforcing bars and the reinforcing members are reinforced by the reinforcing lieers along the peripheries of the corrugated steel plates. However, as the cross-section of the perforated anchor bolts is reduced, local loads There is a problem that deformation occurs.

In order to solve this problem, the invention patent No. 1189620 (registered on October 10, 2012) relates to a steel reinforced concrete reinforced concrete steel reinforced concrete structure having reinforced concrete reinforced structure on the upper part of a base arch structure made of corrugated steel The steel composite structure of the composite steel of the present invention is characterized in that the anchor support pieces are respectively coupled to two valley portions formed on the corrugated steel plate at regular intervals, And an outer surface of the tapered member is welded to both side surfaces of the trough portion. The threaded portion formed at the lower portion of the spacer anchor is inserted into the punching hole of the horizontal member so as to penetrate the twin And a horizontal connection portion is formed at an upper portion of the spacer anchor, And an upper cast iron core is coupled between a lower portion of the horizontal connection portion and an upper portion of an expansion core, and the upper and lower reinforcement rods are coupled to each other. And a plate vertical portion and a channel vertical portion of the channel support portion are coupled to the spacer anchor to which the upper cast iron rope is coupled and the form plate is coupled to both ends of the corrugated end portion of the corrugated steel plate to which the anchor support members are respectively welded, And the concrete is placed in the space formed by the form plate to be hardened.

However, since the reinforcement is formed along the valley between the spacer angles on the upper side and the exhaust reinforcement rods on the lower side, there is a limit to improve the rigidity in the concrete, so that various drawbacks there was.
