Abstract
Description
The present invention relates to a method of constructing a structure using a double wall PC, and more particularly, to a method of constructing a structure using a double wall PC that can quickly and stably construct a structure.
Generally, in order to form a ceiling, a bottom surface, a wall surface, and a column in the construction of an apartment, a mall, a house, a building, and the like, a reinforcing bar is used to form a mold, The reinforced concrete frame is formed by pouring concrete inside.
However, in the above-described construction method, all the processes such as the step of assembling the reinforcing bars to each other by the binding line, the step of installing and removing the formwork, and the supporting and supporting of the supporting slabs are performed at the construction site, And work time. In addition, there is a problem that the construction period is prolonged due to the work schedule because the concrete held until the cured concrete is cured with sufficient strength. There is also a problem that there is a lot of troubles in the disassembly of slab, support and wall formwork, and there is a risk of safety accident.
Particularly, in the process of installing and removing the formwork, a large number of form panels are broken and must be repaired or dismantled. Therefore, not only is the material loss large, but also it takes a lot of time such as the laying process, A carpenter who installs and dismantles a steelwork, a formwork, and a skilled artisan.
The object of the present invention is to provide a method of constructing a structure using a double wall PC capable of rapidly and stably constructing a structure.
The present invention relates to a method of constructing a structure using a double cast concrete (Precast Concrete), in which a first space unit is formed by combining a first space unit and a second space unit to form a space between the first space and the second space, Making a wall paper; And installing a double wall PC on the foundation by positioning a reinforcing member installed to be exposed at an upper portion of the foundation in the spaced space of the double wall PC.
The method of constructing a structure using double wall PC according to the present invention has the following effects.
First, since the insert grooves are formed in the double wall PC, when the floor slab is manufactured on the foundation, the floor slab can be more stably fixed by forming the shear keys inserted in the insertion grooves together. Therefore, a separate structure or process for fixing the floor slab is not necessary, and the effect of shortening the construction time can be expected.
Second, by forming a through slit or a through hole between the insertion grooves of the double wall PC, the reinforcing bar provided when the floor slab is manufactured at the construction site passes through the through slit or the through hole to the inside of the double wall slit Therefore, when concrete is placed in the spacing space of the double wall PC, the fixing force of the double wall PC and the floor slab can be improved by the bonding force with the reinforcing steel.
