[Industrial use]

According to the present invention, the edge PC collecting plate and the internal PC plate are molded in advance in the factory and arranged at the rooftop floor in a lattice form during the construction of the rooftop finishing layer of the building, and then assembled and installed at the same time as the temporary joint plate for installing the expansion joint, and the lattice The present invention relates to a construction method of a rooftop finishing layer in which concrete joints are formed after in situ casting of concrete in the inner space of a mold.

[Private Technology]

According to the conventional construction method of the rooftop finishing layer of a building, after installing a waterproof layer on the upper part of the concrete slab layer, the joint material is fixedly supported by mortar at a predetermined interval on the upper part of the waterproof layer, and the concrete is cast on-site to deposit a nurum concrete of a certain thickness. After hardening the layer, finishing of the roof floor by finishing the ground mortar layer on the upper surface of the nurum concrete layer, that is, bottom gradient work or drainage channel forming work, and installing masonry for protecting the waterproof layer inside the handrail wall. It consists of the construction of the floor.

It consists of constructing the finishing layer of the rooftop.

[Problems with Prior Art]

The prior art is a new joint joint because a plasterer having a special technique directly forms a roof drainage through the manual work of the mortar furnace with a trowel on the rooftop drainage channel formed at the base mortar part around the edge of the rooftop. And labor cost increase due to manpower demand for trench work and work efficiency is deteriorated. Second, after the rooftop drainage is cured, the joint plate material, which is the next process, must be installed, and the joint plate is fixed on both sides of the joint plate material. After the mortar is completely hardened, concrete for the Nurum concrete layer molding needs to be cast as the next step. Therefore, the construction period is delayed by the time when the mortar is cured. There was a problem that deformation occurs, and third, the concrete There is a problem that ground mortar rises or cracks due to thermal expansion, and other roof drainage works are carried out by plastering by mortar at the site, so cement, sand, water, and mortar are stored on the roof. Because the rooftop work site was very dizzy and unclean problem.

[Technical problem to be solved by the present invention]

Therefore, in order to solve the problems of the prior art as described above, the present invention is formed by preforming the PC collecting plate and the inner PC plate for the bottom formed with the bottom water collecting part as a factory product, the upper surface of the waterproof layer formed on the top of the concrete slab layer of the rooftop floor. The PC boards are arranged in a lattice shape at the edge of the rooftop and inside, and fixed installation of the temporary joint mounting material for the expansion joints on the sides of the PC boards, and then cast concrete in the lattice-shaped inner space to harden Next, it is to solve the construction method for forming the finishing layer of the rooftop to form the expansion joint by removing the temporary joint member for installing the expansion joint and filling the caulking material between the gap.

[Purpose of invention]

The object of the present invention is to firstly make the ready-made edge PC collector plate and internal PC plate with the bottom catchment part during rooftop floor construction by simply assembling them into a lattice on the site, thereby reducing the construction period and reducing the construction cost. No need for separate trench work and concrete installation at the same time as installing the temporary joints for expansion joints at the same time as PC plates, so no need for fixing mortar for joints installation It can reduce the manpower and the construction period required for this process. Third, after installing the expansion joints for the expansion joints after the expansion of the concrete joints for forming the Nurum concrete layer, the expansion joints are installed. No breakage or deformation of expansion joints can occur, Since the expansion joints are installed at every interval to prevent uniform phenomenon due to the thermal expansion of concrete. Fourth, the ground mortar is lifted or broken due to the thermal expansion of concrete because there is no need for separate ground mortar work by using PC plates. There is no phenomena, and it is to provide a construction method of the roof top floor of the building to keep the rooftop work site clean and clean at all times during the rooftop finishing work.
