Description

Method of construction of ondol or slab using lightweight insulation panels

The present invention relates to a method for constructing a slab (floor and ceiling) of a building such as an apartment by using a lightweight insulation panel, and simplifies the installation of insulation panels by flooring and ceiling construction that have been constructed through various procedures. The present invention relates to a construction method that contributes to the prevention of safety accidents occurring during construction, reduction of air, and reduction of construction cost by improving the formwork for supporting the insulation panel.

In a multi-storey building, floor structures are installed at certain heights so as to divide the space between floors and use each floor according to a predetermined purpose such as a residence, office, warehouse, and the like. At this time, the lower floor structure of one floor constitutes the ceiling of the lower floor. Hereinafter, in the present invention, the floor structure between each layer is referred to as "slab". The lower slab (ie floor) of each layer thus becomes the upper slab (ie ceiling) of the lower layer.

The slab cross-sectional structure of a conventional apartment building, etc. is as shown in Figure 1, in order to construct this, first install the formwork and reinforce the reinforcement to reinforce the facility, electrical piping, and then cast the slab concrete (30) and then cured, When the concrete 30 is hardened, the foamed concrete 40 is cured on it, and the ondol 50 is plastered thereon. The slab concrete 30 is coated with a ceiling frame and a plasterboard 60 or a night light. Or finish with the paper 70.

However, in the conventional slab construction method, after the slab concrete is hardened, the upper part performs the pouring, curing, and ondol plastering of wet bubble concrete, and the lower part installs the ceiling frame, installs various wirings and pipes, and installs plasterboard and finishing materials. In addition to the need for a complex process such as attaching separately, the thickness of the slab is thickened after completion, there is a problem that the height of the building to increase in order to comply with the legal floor height (層高).

On the other hand, conventional slab construction is first made of plywood or euro foam to form a wall form (wall form) without a special standard process, and the regular length of the wooden support or improved metal tube support at regular intervals After placing the wood horizontally over the foam and the support, the plywood is laid on it to complete the slab foam.

Therefore, according to the conventional method, since the members used for the slab construction are not standardized, it is difficult to continuously use it repeatedly, and it is difficult to accurately maintain the horizontal and vertical of the formwork, and it is difficult to secure stability because the work is performed on an unfixed form. Because the ceiling and wall contact area was difficult to be square, excessive time and manpower was required for the final finishing work, and it was difficult to improve the environment due to the generation of industrial waste such as lumber and steel wire.

The present invention has been made in order to improve the problems as described above, by installing a cushion mat and insulation mat on the thin floor leveling sand (LEVELING SAND) instead of aerated concrete on the slab concrete to increase the noise and insulation effect, formwork Unlike the conventional construction method of attaching the ceiling frame and the plasterboard separately after dismantling, the slab foam is constructed and then the insulation panel is installed from the beginning, the reinforced frame is laid on it, and the slab concrete is poured and cured to form the slab foam. After dismantling, the ceiling work can be finished without any finishing process.

In addition, instead of the conventional foam concrete 40, the cushion mat (2, 3) having the heat insulation and sound insulation effect is employed, and the thickness of the slab is greatly increased by using the heat insulation panel as a substitute for the ceiling frame and the plasterboard or the slab foam. Reduced.

In other words, by using the improved flow form and standardized KICKER CHANNEL and frame instead of the conventional formwork to reduce the weight of the slab foam and install the slab foam simply and easily, the slab foam is warped and irregularities are generated. In order to restrain and to fix the slab foam, the lower part is used to secure the stability and to easily install the formwork and to use it repeatedly, so as to improve the quality due to the precision construction, reduce the construction cost, and reduce the amount of industrial waste.
