The present invention relates to a deck plate having a left and right symmetrical connecting portion is formed spaced apart when the bottom plate and the bottom plate when bonding.

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-symmetrical) deck plate that functions as a male.

As such, the deck plate having a non-left-right symmetrical connection with a male and female problem has the following problem.

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.

Fourth, the bottom plate and bottom plate coupled to each other is not spaced apart from each other, it is necessary to bend the dovetail groove for hanging the hanger. Therefore, the length of the deck plate due to the dovetail groove becomes long.

On the other hand, as another conventional deck plate for solving the non-left-right symmetry of the connecting portion has been proposed in the publication of the Korean Utility Model Registration No. 20-193231.

According to this publication, as shown in FIG. 8, the second deck plate is formed 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 of the 20 '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.

By the way, the center of flat part 26R (26L) is located on the same line as the bending time of deck part 24R (24L). By this configuration, as in the prior art described above, since the lower surfaces joined to each other have a sealed connection portion, bending of the dovetail groove for hanging the hanger is further required. Therefore, there is a problem in that the length of the deck plate due to the dovetail groove becomes long.

An object of the present invention is to provide a deck plate having a structure capable of naturally forming an insertion space of a hanger, which has been devised to solve the above-described problems, and has a left-right 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 by connecting the connection portion of each of the bottom plate and the connection portion of the bottom plate formed on the left and right,

The connecting portion is a left-right symmetrical bending portion,

The space between the bottom plate and the bottom plate when the coupling is formed on the lower surface of the bent portion.

By this structure, the insertion space of a hanger can be naturally formed although it is a left-right symmetrical type which does not distinguish between male and female.

In the above-described configuration, the bent portion may be implemented as an inclined bent portion that is bent upwardly toward the inside of the bottom plate, and an extended 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.

In addition, the bent portion is preferably implemented in an arc shape.

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, the left-right symmetrical form of this embodiment shall include not only the left-right symmetrical state in the combined state, but also a manufacturing dimension dimension error, a deformation | transformation in handling, handling, and a deformation | transformation at the time of joining.

1 is a front view showing a truss deck having a connection according to a preferred embodiment of the present invention, Figure 2 is a front view combined with the connection of FIG.

As shown in Figures 1 and 2, the truss deck 100 of the present embodiment is composed of the truss 130 and the deck plate 150 described above.

The truss 130 is largely composed of a unit of the upper root 131, the lower root 133, and the lattice 135. Three trusses 130 composed of one unit are normally fixed to the deck plate 150 at predetermined intervals.

The deck plate 150 includes a bottom plate 151 and connecting portions 153 and 155 which are installed at both sides of the bottom plate 151. These connecting portions 153 and 155 are bilaterally symmetrical bent portions. When the left and right symmetrical connecting portion 153 and the connecting portion 155 are coupled, a space 110 is formed on the lower surface thereof. Since the space 110 is formed while being spaced apart from the bottom plate 151 and the bottom plate 151, it is possible to naturally form a row or insert insertion space.

In addition, the bottom plate 151 is preferably formed with a rib 157 for the convenience of spot welding. The rib 157 is such that the foot 136 of the lattice 135 is fixed.

The truss decks 100 are connected to each other by the left and right symmetrical connecting portions 153 and 155 formed on both sides of the deck plate 150 and are continuously placed on the slab. Then, concrete is poured on it.

As described above, the bent portions 153 and 155 having the space 110 formed on the bottom surface when being symmetrical and coupled are toward the inner side (the side facing the bottom plate) of the bottom plate 151 as shown in FIG. 2. An inclined bent portion 153a, 155a, which is bent upwardly and inclined upward, extends outwardly from the bottom plate from the inclined bent portion 153a, 155a. In addition, the center of the extension bent portion is at a position protruding outward from the viewpoints of the inclined bent portions 153a and 155a. In other words, the center of the extended bent portion (return points of the first extended bent portion and the second extended bent portion) is located outside from the viewpoints of the inclined bent portions 153a and 155a by the distance Δ.

As such, due to the securing of the distance △, the space between the bottom plate 151 and the bottom plate 151 is spaced, and a space 110 for inserting the hanger is naturally formed, and it is necessary to bend the dovetail groove. The length of the bottom plate is reduced. In addition, since the extension bent portion of the left connecting portion 153 and the extension bent portion of the right connecting portion 155 are each bent outwards to be left-right symmetrical, it can be combined regardless of the orientation of which is superimposed (Fig. 3 and FIG. 4).

In addition, the extended bent portion is a first extension bent portion (153b) (155b) is bent inclined upwardly toward the outer side (the side away from the bottom plate) of the bottom plate 151 in the inclined bent portion (153a) (155a), and It is preferable that it is comprised by the 2nd extension bending part 153c and 155c bending inclined downward toward the outer side of the bottom plate 151 by the 1 extension bending part 153b and 155b.

As such, the space 110 formed through the coupling of the left connecting portion 153 and the right connecting portion 155 serves as a dovetail groove.

In particular, while the inclined bent portion (153a) (155a) performs the same function as the inclined surface of the dovetail groove, while performing the function of supporting the free ends (153d) (155d) of the extended bent portion, it is suppressed to be pressed by the concrete Can be. Therefore, the space 110 may perform its function stably like the dovetail groove.

In addition, as shown in FIG. 3, even when the second extension bent portion 155c on the right side is deformed as a solid line, when combined with the left connecting portion 153, the construction is deformed to a normal state while being extended as a dotted line. It is convenient.

Similarly, as shown in FIG. 4, even when the second extension bent portion 155c on the right side is deformed like a solid line, when combined with the left connecting portion 153, the construction is deformed while being deformed like a dotted line. It is convenient.

On the other hand, the space (110) is formed in the connecting portion (153, 155), the upper end of the connecting portion is easily pitted by hitting a hammer or the like. This recessed portion forms a long flow path and makes a complicated structure, so that the gap between the connecting portion 153 and the connecting portion 155 can prevent the leakage of concrete more reliably.

Meanwhile, as shown in FIG. 5, the entirety of the connecting portions 253 and 255 may be implemented in an arc shape. The arc-shaped connecting portions 253 and 255 are convenient to bend, and can be obtained simply by pressing the upper ends after being combined with each other to obtain a shape and space 210 such as a dovetail groove.

In addition, as illustrated in FIG. 6, the extension bent portions 353b and 355b may form the extension bent portion of FIG. 1 in an arc shape to secure a space 310 at the time of coupling.

The deck plate of the present invention is not limited to the above-described embodiment and can be carried out in various modifications within the range allowed by the technical idea of the present invention.

As is apparent from the above description, the deck plate of the present invention has the following effects.

First, the left-right symmetrical type, by combining the configuration of the connecting portion is formed on the lower surface while the space between the bottom plate and the bottom plate when combined, (1) it is possible to insert a hanger, etc. in the naturally formed space, No need to form dovetail grooves, reducing the length of the bottom plate and simplifying the manufacturing process. (2) Left and right symmetrical connecting parts can be combined in any direction and can be combined. There is no inconvenience, and (3) even though the connection part is deformed, the deformed part is naturally adjusted through the coupling between the connection parts. It can surely prevent the leakage of moisture.

Second, the inclined bent portion is bent upwardly inclined upward toward the inner side of the bottom plate and the extension bent portion extending from the inclined bent toward the outside of the bottom plate, whereby the inclined bent portion supports the free end of the extended bent portion It can function more securely in the space of hanger even if pressed by the cast concrete.

Third, since the connection portion is implemented in an arc shape, it is easy to bend, and can be obtained simply by pressing the top of the top and then combined with each other to obtain the shape and space like the dovetail groove.
