Description

A floor system of access-floor type with an iron sheet and a glass-ondol and the construction method of it}

The present invention relates to an access floor type floor structure having a heat dissipation plate and a glass hot plate which is specially constructed and assembled so that heat transfer is good, and the present invention relates to the present applicant's "Application No. 10-2001-0003354, Glass Ondol." Access floor type floor structure and its construction method using the "Invention" to supplement the problems appearing in the process of applying to the actual construction and to further develop.

The floor heating method of a house including a current apartment house (apartment, etc.) in Korea is to install a thermal insulation material 13 on the concrete slab 12 and form a heat storage layer such as a gravel layer 14 thereon as shown in FIG. And it is a general aspect that the hot water pipe 15 is buried in the heat storage layer and the cement mortar 16, the bottom finish material 17 as a heating pipe.

The wet floor structure, which is a conventional floor heating system, is mentioned in the previous application (App No. 10-2001-0003354, Access floor type floor structure using glass ondol and its construction method), as mentioned in the apartment structure from the West. Improperly applied, the lifespan of the apartment itself is about 20 years, which is only 1/3 of that of 60 years abroad, due to various problems caused by laying pipes in concrete, replacing them, and repairing them. It has many problems such as complicated process, noise, difficulty of dismantling materials, excessive repair cost, excessive energy waste, and noise and dust when replacing or repairing the facility piping (heating, water supply, hot water supply, drainage) on the floor of the apartment. Causes physical and physical damages between residents and neighboring households due to wastes and wastes. In case of occurrence, it is necessary to break and break several places in order to identify the source of the defect, and even if it is difficult, it must be difficult to break and break the concrete floor to repair the defect such as plumbing work. Since the construction of the gravel layer, cement mortar, etc. had to be reestablished, it was costly and time-consuming, therefore, despite the remaining life of the building itself, Article 4-2 of the Enforcement Decree of the Housing Construction Promotion Act due to the aging of plumbing etc. As a result of being reconstructed and destroyed and rebuilt apartments that are less than 20 years old, less than one-third of the lifespan of foreign apartments is happening, which is causing great waste in the country. The heat storage layer such as the gravel layer 14 and the cement mortar 16 are increased by increasing the floor load. The energy consumption was severe because the preheating load caused by the heat storage layer and the occupant were vacant from the house while the boiler was shut down or the heating valve was closed. In addition, in order to increase the comfort of the occupants by uniformly distributing the temperature on the floor surface, the hot water pipe 15 had to have a diameter of 15 mm and was regularly circulated at intervals of 20 to 25 cm. Since the temperature of hot water is also restricted (usually below 60 ° C), more pipes are wasted than actual piping required for radiant heating. In addition, many construction wastes are generated when replacement works or repairs are being made, which greatly affects the environment. On the other hand, the existing produced access floor needs to keep the concrete slab flat evenly in order to level the floor, so it is necessary to separately finish the concrete slab flatly, and the support is spaced between the four corner support points. This narrow, thin glass plate could not be supported, and because the flat plate was thick, the free space at the bottom was small and the heat permeation rate was low. Therefore, there was little effect of radiant heating using hot water ondol radiant heating or warm air.

Accordingly, in order to solve the above problems, the present applicant has developed and grafted core technologies such as "access floor type floor structure" (hereinafter floating floor structure) and "glass ondol" and "access floor type floor structure using glass ondol, and its Construction method (Application No. 10-2001-0003354) "was developed and a patent application was applied. Then, to apply the applied technology to the actual construction site, research desirable structure, shape, structural performance (durability, strength, etc.) and As a result of the actual measurement of the heating environment (heating performance) and the heat permeation rate, which are important parts of the environment, the actual construction environment did not come out as much as the applicant wants, and thus, a more efficient structure for radiative heating and cooling was studied. As described above, the floor system has been developed, which is more advanced and superior in performance than the present invention.

The present invention has been made to solve the above problems, the object of the present invention is to manage the replacement and maintenance of the piping and wiring of the apartment house conveniently and economically managed to solve the economic and mental burden of the tenants and inside each household It is to provide a floor structure with high space utilization and its construction method by moving the installed main pipe and ventilation fitting to the common part (stair room or corridor).
