The present invention relates to a deck plate used in construction and civil engineering structures, and more particularly, easy reinforcement of reinforcing bars, remarkably improved the adhesion strength with the concrete to be poured and has a beautiful appearance in the mass production in the factory as water The present invention relates to deck plates for reinforced concrete construction and civil engineering structures.

Reinforced concrete structure is a composite structure in which concrete and reinforcing bars having different physical properties are used together as compressive and tensile materials, respectively, which form a form to form the outer surface of concrete, reinforce the steel in the form, and inject concrete to cure When this is completed, it is achieved by removing the formwork, which makes up the main structure of the building structure.

Among these reinforced concrete structures, especially in the case of construction and civil engineering structures, the top plate is constructed by mounting a beam on a pier, installing a scaffold for work on a beam, installing a lumber shell, passing a plywood formwork, and then placing concrete on the upper surface of the formwork. It is usually by way of pouring.

In this case, the formwork is constructed of plywood, lumber, etc., which requires construction work to perform reinforcement work such as reinforcing bars and dismantling work to dismantle the formwork after curing of concrete, which requires a considerable construction period.

In particular, these structures are easy to attach to the concrete surface and formwork, and after completing the curing of the concrete, it is difficult to separate the formwork from the concrete, and it is also difficult to separate the formwork from the hardened concrete. As a result, the surface of the structure became poor and a separate surface finishing work was required.

In addition, since the formwork made of a material having a weak durability is generally damaged during the dismantling operation, it is difficult to reuse, causing a problem of generating a large amount of waste materials.

In addition, in the case of the prior art, installation, dismantling, and transportation of the lumber ridges and plywood formwork are inevitable. Most of these operations are performed by on-site laborers. There is a problem that the construction period is prolonged because a separate scaffolding work must be preceded.

In addition, in the case of construction and civil structures, the construction site is made at high altitudes, so there is a high risk of safety accidents, and there is inconvenience of installing a separate safety facility.

On the other hand, as a method for improving the problem, a method that does not use the formwork, that is, a method that uses the member used to form the outer surface of the concrete as part of the reinforced concrete structure as shown in Figure 1a, 1b and 1c (D) is used.

The deck plate (D) is bent in a right angle or trapezoidal shape as shown in FIG. 1c, where reinforcing bars and concrete are poured and used as a top plate of construction and civil engineering structures.

As shown in Figure 1a the main reinforcement (T) is supported by the hoop reinforcement (H) is installed on the deck plate (D), the longitudinal reinforcement (L) and transverse reinforcement to form a reinforcing bar (W) on top (S) is bound to be sequentially arranged and arranged to be mutually supported by the spacer (S2) between each other, or as shown in Figure 1b, the reinforcing bar (W) is configured in advance in the form of a lattice welding and the reinforcing bar (W) The reinforcing bar T is suspended by the spacer S2 while the reinforcing bar network W is supported on the deck plate D by the spacer S2 or the like.

However, the method using the deck plate (D) is only a difference that no formwork is required compared to the prior art, and the top surface of the deck plate (D) is smooth, so that a predetermined reinforcing bar must be added separately for attachment with concrete. In this case, the reinforcement process is no different from that of the general process, and thus, problems such as workability and economic feasibility were still not solved.

Therefore, there is an urgent need for the development of deck plates that do not need to be installed and dismantled, such as formwork, clubbing, simple reinforcement of the reinforcement, and sufficient adhesion to concrete.

The present invention overcomes the problems of the prior art as described above, since it is used as a top plate of the building and civil construction to be integrated with the concrete to be poured, so no formwork, clubs, etc. is necessary, and provided with an attachment reinforcement on the upper surface of the deck plate and the concrete It is an object of the present invention to provide a deck plate that can increase adhesion and facilitate reinforcement of rebar.

In order to achieve the above object, the present invention is the first embodiment,

A panel mounted between the beams and having a bent portion, the panel having embossing at regular intervals on the upper surface thereof;

Attached to the bent portion of the panel, the upper flange, the abdomen and the lower flange, characterized in that consisting of an attachment reinforcement is provided with an attachment hole.

On the other hand, as a second embodiment of the present invention,                         

A panel mounted between the beams and having an embossing on the upper surface at regular intervals,

The panel is attached to the upper flange, the abdomen and the lower flange, characterized in that consisting of an attachment reinforcement provided with an attachment hole.

As a third embodiment and a fourth embodiment of the present invention,

In the first or second embodiment described above, the shape retaining member is additionally installed.

As a fifth embodiment of the present invention,

A single steel sheet is bent vertically upward, and the steel sheet is bent vertically downward so as to be in close contact with the steel sheet bent vertically upwards to form an abdomen, the upper end of the abdomen is cut and then bent to form an upper flange. By bending the steel plate in the horizontal direction at the bent portion to form a panel, and repeating the above process to form at least one or more abdomen, the abdomen and the panel is formed integrally, at least one or more attachment voids in the abdomen And at least one emboss is formed on the panel.

Therefore, the object of the present invention, by constructing the construction and civil engineering structure by the characteristics of the present invention as described above compared to the conventional technology, the mass production is possible in advance in the factory with the pre-assembled cast iron rebar, It is to provide a deck plate for reinforced concrete construction and civil structures with excellent workability and economical efficiency and uniformity of product quality as well as excellent strength.

Hereinafter, with reference to the accompanying drawings with respect to the configuration of the preferred embodiments of the head reinforcing device for steel pipe piles according to the present invention will be described in detail.

Figure 2a is a perspective view of the attachment reinforcing material 41 of the deck plate according to the present invention. As shown in FIG. 2A, the reinforcement reinforcing material 41 according to the present invention has an upper flange 43 alternately formed at the upper part of the abdomen 44 with each other alternately, and at the center of the abdomen 44 with concrete. There is an attachment hole 42 in the longitudinal direction to reinforce the adhesive force, the lower portion of the abdomen 44 has a lower flange 45 attached to the panel 100.

In the case of the upper flange 43 by cutting the upper portion of the abdomen 44 and by bending the upper side of the cut abdomen 44 to the left and right, so as to be alternately formed in the left and right directions of the abdomen (44).

As shown in Figs. 1A, 1B and 1C, the upper surface of the deck plate is smooth in the prior art, so that sufficient adhesion with concrete cannot be secured, and for this reason, the longitudinal roots (L) and the transverse direction (S) are absent. Or the reinforcing bar (W) is required separately, but in the case of the deck plate according to the present invention can ensure sufficient adhesion strength due to friction and mechanical action of the abdomen 44 and the upper flange 41 with the hard concrete, and therefore separate No reinforcement or rebar network (W) is required.

Of course, when the increase in strength is required, such as the reinforcement of the transverse direction (S) and longitudinal direction (L) rebar or the installation of the reinforcing bar (W) according to the prior art as shown in Figures 1a, 1b and 1c It may also be parallel to this configuration as it will be apparent to those skilled in the art from the present invention will be considered to belong to the technical scope of the present invention.

In FIG. 2A, only upper flanges 43 are alternately arranged horizontally to the left and right sides of the abdomen 44. However, the upper flange 43 and the upper flange 43 and the abdomen 44 are provided within a range capable of securing a predetermined attachment strength. The angle may be configured as an acute angle or an obtuse angle.

The attachment hole 42 has a circular shape and is formed in the abdomen 44 in the longitudinal direction of the attachment reinforcing material 41, when the concrete hits the upper portion of the deck plate according to the present invention concrete attachment hole 42 Since it fills through it serves to increase the adhesion strength between the deck plate and the concrete.

Meanwhile, in FIG. 2A, only the circular shape of the attachment hole 42 is illustrated, but the shape of the attachment hole 42 may be square, within the range in which the transverse rebar 53 may be fixed through the abdomen 44. Of course, it can also be in the shape of other polygons, such as hexagons, ovals.

The number of attachment holes 42 shown in Figure 2a is only one embodiment of the deck plate according to the present invention can be appropriately increased or decreased according to the required strength of the structure in which the deck plate according to the present invention is used. These modifications will be described as belonging to the technical scope of the present invention because it can be easily predicted by those skilled in the art as much as possible from the present invention.

The lower flange 45 is coupled by welding perpendicular to the abdomen 44 and the bottom surface thereof is in intimate contact with the upper surface of the bent portion 52 of the panel 100 to couple the attachment stiffener 41 to the panel 100. To act.

2B is a perspective view showing another embodiment of the attachment reinforcing material 41 according to the present invention. The abdomen 44 is formed at right angles to the lower flange 45 along the central portion of the lower flange 45, and the attachment hole 42 is provided in the abdomen 44 at regular intervals as in FIG. 2A.

However, the attachment reinforcing material 41 in FIG. 2b is configured to not include the upper flange 43 formed by alternately bending the cut upper portion of the abdomen 44 from side to side as in FIG. 2a.

In the case where the attachment strength of the structure can be secured sufficiently without forming the upper flange 43, the workability can be improved by using the attachment reinforcing material 41 as shown in FIG. 2B.

Figure 2c is a perspective view showing another embodiment of the attachment reinforcing material according to the present invention. The abdomen 44 is formed at right angles to the lower flange 45 along the central portion of the lower flange 45, and the attachment hole 42 is provided in the abdomen 44 at regular intervals as in FIG. 2A.

However, instead of forming the upper flange 43 by alternately bending the cut upper piece of the abdomen 44 to the left and right as in FIG. 2A, a rectangular steel sheet is attached to the abdomen 44 to form the upper flange 43a. , The attachment reinforcing material 41 according to the present invention has a shape of the H-shaped steel as a whole while the upper flange 43a is smaller than the lower flange 45.

In FIG. 2C, the width of the upper flange 43a is smaller than that of the lower flange 45, but the relative sizes of the width of the upper flange 43a and the width of the lower flange 45 are the construction environment and required strength of each structure. It will be possible to appropriately adjust according to this will be said to belong to the technical scope of the present invention as merely a simple design change of the present invention.
