The present invention relates to a deck plate having a connecting portion of the left and right symmetrical contact between the bottom plate and the bottom plate when engaged.

Background Art Conventionally, for example, the one disclosed in the publication of Korean Utility Model Model No. 20-0203627 has been proposed as a deck plate. As shown in FIG. 7, the conventional deck plate 10 includes an anchor portion 12, a dovetail groove 11 formed to easily hang a hanger, and a connection portion 13 and 14 for connection with another deck plate. It consists of. Of course, the truss consisting of the upper, lower, and lattice instead of the anchor portion 12 may be fixed to the deck plate 10 (see Korean Utility Model Registration No. 20-0323006). One end of the connecting portion is folded vertically and the end is folded at right angles twice to form an inner connecting portion 13 positioned inside, and the other end is folded in the same structure as the inner connecting portion 13, and the inner connecting portion 13 The outer connecting portion 14 is formed to be folded to a size to be covered on the outside. That is, the inner connecting portion 13 is a female, the outer connecting portion 14 is a male and female (non-left symmetric) deck plate that functions as a male.

Moreover, as a deck plate which is asymmetrically asymmetrically of a connection part, what was disclosed by the publication of Korean Utility Model Registration No. 20-193231 is proposed. As shown in FIG. 8, the second deck plate 20 ′ is provided inside the space portion formed by the left deck portion 24L, the flat portion 26L, and the locking portion 28L of the first deck plate 20. The right deck portion 24R, the flat portion 26R and the locking portion 28R are inserted. Then, an inverted triangular connection portion is formed by the right deck portion 24R, the flat portion 26R, the locking portion 28R, and the left deck portion 24L of the first deck plate 20 of the second deck plate 20 '. 30 is formed. At this time, the left flat portion 26L of the first deck plate 20 and the right flat portion 26R of the second deck plate 20 'overlap with each other, and the right latch of the second deck plate 20' is engaged. The portion 28R is in contact with the outer surface of the left deck portion 24L of the first deck plate 20.

As such, a deck plate having a non-symmetrical connecting portion for distinguishing male and female has the following problems.

First, if the deck plate is coupled from both sides of the slab male connector and the male connector, or the female connector and the female connector on both sides, it can not be combined into a deck plate having male and female connections. In other words, pay attention to the orientation of the connection.

Secondly, when constructing while joining on one side of the slab, the remaining length is short and the deck plate is cut and the remaining part is inconvenient to reuse when the male and female fit.

Third, when the deformation occurs in the connection portion, there is an inconvenience that the operator must correct the deformed portion when not coupled to each other when combined.

The present invention has been made to solve the above-described problems, and an object thereof is to provide a deck plate having a structure of right and left symmetry without distinction between sexes.

In the deck plate of the present invention for achieving the above object is a deck plate which is constructed on the slab is coupled to each connection portion of the bottom plate and the connection portion of the other bottom plate formed on the left and right,

The connecting portion is a bending portion that is symmetrical left and right,

When joining, there is a contact between the bottom plate and the bottom plate.

By this structure, there is no distinction between male and female, and construction is very convenient.

In the above-described configuration, the bent portion may be implemented as an inclined bent portion bent upwardly toward the inside of the bottom plate, and an extension bent portion extending toward the outside of the bottom plate in the inclined bent portion.

In this case, the first bent portion is bent inclined upward toward the outside of the bottom plate in the inclined bent portion, and the first bent inclined downward toward the outside of the bottom plate in the first extension bent It is preferable that it is comprised by a double extension part.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, which are defined as the left connection part and the right connection part when viewed from the drawing with reference to one deck plate.

In addition, since the connection part of this embodiment is bent-molded in two shaping | molding rolls which have the same size (shape and size), it means that it was formed by the left-right symmetry which has the same size and shape.
