Description

A deck structure for forming a concrete floor of a building,

The present invention relates to a deck structure for forming a concrete floor of a building, and more specifically, a reinforcing frame can be easily installed to improve the rigidity of the reinforcing bars at the time of construction of a concrete floor of a building, It is possible to simplify the installation of the reinforcing frame in the reverse trapezoidal grooves of the deck plate such as the deck plate and the U deck, To a deck structure for a concrete floor forming structure of a building capable of shortening the construction period and shortening of air and securing a good quality of the position of the reinforcing frame in the concrete.

Generally, the bottom slab structure of concrete structures is a composite structure that uses concrete, which is a compression material, and reinforcing bars, which are a tensile material, and is the main type of floor structure.

The most common method for constructing the floor slab of such a concrete structure is to install the concrete to form the bottom surface of the concrete, to reinforce the concrete, and then to inject the concrete, and the curing process is completed.

This method requires a considerable period of construction time due to the difficulty due to the construction and disassembly of the formwork, the requirement of separate reinforcement work, the separate finishing due to the surface defects of the structure, and the like, Economic and environmental pollution.

Therefore, it is known that a method of not using a mold, that is, a method of using a structure used for forming a floor of a concrete as a part of a concrete building, is known as a method for improving the problem of using the form.

In this moldless method, a reinforced concrete slab was used or a deck plate improved to a greater extent.

However, the construction method using the PC slab has a disadvantage of not only a heavy structure but also a thickness of the slab, which lowers the layer height. Since the PC slab itself is a heavy structure, And the logistics cost to be stored is enormous. In addition, a lot of unnecessary loading space is occupied in the field. Also, it is difficult to cope with the changed parts such as the change of the drawings, and since the heavy structure is a heavy structure, There has been an unreasonable problem such as a safety problem and a long construction period as a whole.

To solve these problems, a deck plate for placing on a steel frame has been widely used. However, in the case of a deck plate, the distance between the two horizontal beams is within 3 m when the deck is a bone deck, , It is used within 4 m, but when it is longer than this, the strength is weak and it can not be used.

A conventional building deck plate having other types of concave and convex grooves is formed by including an upper plate 11, a side plate 12, a lower plate 13 and connecting means 15a and 15b as shown in Fig. And two unit bodies each composed of the top plate 11 and the side plate 12 constitute a unit unit. The lower plate 13 is bent at the lower end of the side plate 12 and is formed in the center of the unit parallel to the upper plate 11 and the connecting means 15a and 15b are formed at both ends of the unit.

Further, the connecting means 15a and 15b formed at both ends of the unit are formed of the 'r' shaped 15a which is laid down laterally and the 'C' shaped opening 15b which is opened upward, The width in the engaged state becomes the same width as the width of the lower plate 13 while being 'C' shaped by 90 ° clockwise. As shown in Fig. 1, the trapezoidal groove 16 of the deck plate 10 is horizontally disposed on the upper portion of the deck plate 10 and spaced apart from the deck plate 10 by a spacer 19 Shaped ring 21 is inserted on the transverse reinforcement 20 and a lower reinforcing bar 22 is disposed on the lower portion of the S-shaped ring 21 to form the bottom surface 13 of the deck plate 10, And the upper reinforcing bars 23 are disposed horizontally at right angles to the transverse reinforcing bars 20 to form a steel frame structure. When the steel frame structure is completed, a deck plate 10) in order to cure the concrete bottom layer (not shown).

In such a case, not only the time and effort required for forming the steel structure take much time, but also the transverse reinforcing bar 20 is touched by the movement of the transverse reinforcing bar 20, so that the spacer 19 is released, A large amount of manpower is required to install the steel frame structure 17 on the deck plate 10, thereby increasing the risk of safety accidents. In addition, the construction cost is increased, and the construction time is increased There is a problem that the entire air is lengthened.
