Description

Prefabricated Panel for Ondol {a prefabricated panel for ondol}

The present invention relates to a prefabricated panel for ondol, which is energy-saving and reinforced with interlayer noise blocking function. More specifically, it is light and has excellent thermal insulation performance and soundproofing effect, but the strength of raw materials is not easy to use as a building material for floors. Inside the lightweight styrofoam panel, a large number of high-strength reinforcement pedestals are placed to prevent damage due to external shocks and noises, as well as noise-absorbing means. The present invention relates to a prefabricated panel for functional ondol, which can be used for both dry and wet ondol methods, which are standardized in the same form in order to improve the efficiency of ondol construction.

Typically, the ondol method used in conventional buildings is divided into a wet method using cement mortar and a dry method without using water. The wet method uses ondol floor insulation material to cover the foam concrete, which makes light weight by making many bubbles in concrete without using fine aggregates, and fix the heating hose for heating hot water circulation on the top surface of the foam concrete, and then use cement mortar to make the ondol floor. Was completed. As such, stones or aggregates, such as sand, gravel, and cement, which are mainly used in the wet ondol method, are heavy, and the total load of buildings increased due to the installation of ondol has led to an increase in the cost of the basic framework.

In particular, lightweight foam concrete installed at the bottom of the ondol used for floor insulation has a problem that it is vulnerable to external impact with low strength, so that a large amount of cement mortar is cured on the upper surface of the foam concrete for the purpose of preventing breakage of foam concrete during ondol construction. As a result, the thickness of the ondol floor is increased and the indoor space is reduced.The heating heat generated from the heating hose reaches the ondol floor is late, and when the heating is unnecessary, the ondol floor is cooled late. Increasingly, water-based cement mortar and foamed concrete had a problem of delaying the total construction period because they could not work in other fields until they were completely cured.

In addition, the general dry ondol method has an ondol structure of a combination installation method using styrofoam, but uses only styrofoam, which is a raw material of ondol, without a separate protection device against load and impact absorbed from the upper side, by simply increasing the thickness and density. In this case, the indoor floor becomes narrower as the ceiling is lowered due to the elevated ondol floor.Styrofoam is an organic chemical substance, and it is difficult to bond with inorganic binders such as cement and lime powder, and it is impossible to use it, and it can be used on the surface of the styrofoam panel. Floor finishing materials are limited to varieties used in the assembly and installation method, such as wood flooring or synthetic resin floorboards, so it is not easy to use ondol finishing materials of inorganic materials such as marble or ceramic tiles.

In addition, the pipe work without a separate heating hose fixing device for piping the heating hose of the crosslinked polyethylene material that is hard and not bent on the ondol floor has a problem that it takes a lot of time to increase labor costs.

In order to improve such a conventional problem, the present inventors use styrofoam as the material for the flooring material to reduce the weight of the building by thinly and prefabricated panel form to reduce the load of the building, reinforcement pillar forming ball to protect the weak styrofoam panel Registered a utility model to protect from external shocks and to form a heating hose pipe groove that can easily pipe a heating hose to reduce labor costs by simple construction (Registration No .: 20-0415190, Design Name of "Prefabricated Panel for Heating Heating").

Such inventors registered the "prefabricated panel for ondol heating" had the effect of sufficiently improving the conventional problems, but the design can be used only in the wet method, and the problem of the need for use in the dry method and weakness in preventing noise between floors inside the building. It was necessary to reinforce it.

The present invention can be used regardless of the type and varieties of the flooring materials for the construction of the ondol, reducing the increase of the load on the building due to the raw materials, increasing the thermal insulation efficiency, increasing the energy saving effect, and adding the interlayer noise blocking structure. The purpose of the present invention is to provide a functional ondol prefabricated panel that can increase the noise blocking effect between the floors inside the building, and to reduce labor cost of workers due to simple and easy assembly and installation.

The present invention relates to a prefabricated panel for ondol construction, which is used for both dry and wet methods. The panel body is formed of lightweight styrofoam having excellent thermal insulation performance and soundproofing effect. The heating hose fixing groove is formed in the direction of the curve and curves, and from the top to the bottom on the other side of the panel where the heating hose pipe groove does not pass. It is characterized in that the plurality of pedestal insertion hole penetrated downward.

In addition, the heating hose fixing groove formed in the upper half of the panel according to the present invention is characterized in that the heating hose fixing grooves are interconnected to each other even when the different panels and panels are installed and installed in four directions, the heating hose is configured to correspond to the extension do.

In addition, the structure of the reinforcing pedestal is assembled and fixed to the pedestal ball according to the present invention has a junction space that can be injected into the upper half and the lower half in a constant size and depth, the shape is wider around the top and toward the bottom It is an inverted rhombus with narrow circumference.The pedestal is made of foamed concrete (ALC) or cement dough made by curing under high temperature and high pressure with autoclave using sand and quicklime containing a lot of silica as main raw materials. It is characterized by being formed in the same shape and size as the pedestal insertion hole with a high-strength material for producing foam concrete cured from raw materials.

In addition, the lower side of the panel according to the present invention is characterized in that the noise blocking layer interlayer material is configured as a means for blocking the noise generated from the ondol floor is transmitted to the lower floor inside the building.

According to the present invention, in the construction method of ondol, both wet and dry methods can be used regardless of the method, and the same ondol panel can be used regardless of varieties of floor finishing materials. Create the environment, greatly reduce the load on the building, reduce the cost of basic construction, and reduce the labor cost and excellent thermal insulation effect by simple heating hose piping work to increase the heating efficiency, thereby saving energy.
