Description

The girder form construction method using the deck composite}

The present invention relates to a method of forming a formwork of reinforced concrete structure, the deck form reinforced reinforced sheet rigidity is easy to install lightweight and easy to install, and after the curing of the concrete formwork improved formwork formwork and deck combination It relates to an improved formwork installation method using.

Reinforced concrete structure is a very excellent construction method because it forms a structure by hardening by pouring liquid concrete into formwork.

However, since the structural role of reinforcing steel and concrete is possible only after the concrete is hardened, the formwork should be able to support the liquid concrete and reach a certain strength until the concrete is hardened and structurally stable.

The beam formwork is composed of one bottom plate and two side plate forms with 'c' shape, which is opened on the top, so that the material and construction loads including reinforcing steel and concrete act on the bottom plate and the horizontal load by fluidization of liquid concrete This occurs and the side pressure to push out the side plate acts and requires reinforcement.

1 shows a method using a conventional plywood formwork.

As shown in FIG. 1,

On the bottom plate BB, joists (J) and yokes (Y) are installed at predetermined intervals to reinforce the rigidity of the plywood and transmit the load to the support (not shown).

In the side plate (SB), the horizontal reinforcement (P) and the long binding material (PT) are installed to bear the concrete side pressure and increase the plate rigidity of the side plate (SB), and the fixing steel (G) for fixing to the horizontal reinforcement (P) is provided. Many are provided in response to side pressure.

In addition, the reinforcing material that transfers the construction load of the coupling reinforcement (CP) and the slab formwork (SLB) to reinforce the bottom plate (BB) and the side plate (SB) to the side plate (SB), and combines the slab formwork (SLB) and the side plate (SB). It consists of many members such as (SLP) and requires the most effort in the formwork process.

In addition, since the concrete is demolded at a high position after hardening, the difficulty of the work is high and it is very dangerous.

The construction industry, which is classified as a representative 3D industry, has a serious problem of labor shortage, and there are limitations in manpower-oriented construction methods in the field. There is an active research on prefabrication.

Even in the most widely applied reinforced concrete ramen structure, the slope formwork method is applied to eliminate dangerous formwork while minimizing the process in the field by minimizing the process in the factory due to this effect.The representative method is the PC method and the Half-PC method. There is this. That

However, such a PC-based method is difficult to transport and install due to the heavy weight of concrete, and a bent formwork method using a bent iron plate or a deck plate that is lightweight by combining steel plate and steel bars has been proposed.

The most complex beam formwork method in slope type formwork using deck plate is proposed to use steel plate as structural material for fireproof structure (10-0872959) and formwork function only (10-1009753, 10-1777979). It is becoming.

Patent 10-0872959 uses a thick steel sheet to minimize the burden on the copper bar and to be used as a structural material, but it is difficult to handle with heavy materials and economical, so it is applied only in the differentiated field such as long span structure, there is a limit in the versatility.

Patent 10-1009753 is light and easy to handle with the use of a thin deck plate, but the deck plate alone can not withstand the side pressure, and the long binding (side plate support member) mechanically combined with the horizontal bead of the side plate, but the bonding force is not strong, easy to escape, Combination of the bottom plate and the side plate only overlaps the bent plate, so there is a disadvantage in that it is difficult to install due to weak form maintenance for external force.

Patent 10-1777979 is a bottom plate and the side plate is combined only by the bent portion to reinforce the disadvantages of maintaining the shape of the external force by welding the ribs on the bottom plate and the bead of the side plate, but after joining the bottom plate and the side plate and the ribs are welded the formwork becomes independent Because it is possible to maintain the shape, the welding of the root is essential, but the welding work is manual and the production is difficult due to the uncomfortable posture and excessive welding in the assembled formwork, and the productivity is poor, and the welding is applied to the structural function. Containing anxiety, because the side pressure acting on the side plate is not enough to the welded roots, there is a disadvantage in that the process of installation and dismantling is added because a conventional reinforcement method using a long binding material and a reinforcement is required.

In addition, since the reinforcing bars are intricately bound between the main bar and the frame, it is common to insert them into the formwork after assembling them in a factory or on the site, rather than reinforcing them in the formwork.

It is very difficult to install the long binding material in the form in the state where the reinforcing bars are arranged as in Patent 10-1009753, and when the frame is lined as in Patent 10-1777979, there is a difficulty in entering the lower reinforcing bar into the form. There is a need for improvement.

Accordingly, the present invention relates to a formwork method of reinforced concrete structure, economical and easy to manufacture and construction, low probability, and can be compatible with prosthetic reinforcing bars assembling integrally in the factory or the field, and reinforced sheet strength The deck formwork is easy to install with light weight, and after the curing of concrete, it has been developed an improved formwork installation method using improved formwork and deck combinations that permanently function as structures without demoulding.
