Description

{ONDOL FLOORING BOARD OF DRY TYPE}

The present invention relates to a dry floor heating floor material, and more particularly, to a dry floor heating floor material installed on a floor of a residential building such as a single-family house, a villa, an apartment, and the like to circulate hot water for heating.

Generally, the heating system applied to residential buildings such as single-family houses, villas, apartments, etc. is a wet-type method. The wet method is a structure in which a pipe is buried in a concrete floor, and a heating fluid such as hot water is supplied to the pipe to heat the floor.

However, such a wet heating system has a low heat efficiency and a large heat loss, and the concrete curing takes a long time during the construction, which leads to a longer construction period. In addition, since the bottom surface of the mortar layer must be digested in the event of the leakage of the pipe due to the aging of the pipe, the maintenance of the heating system is troublesome and the maintenance cost is also high.

In order to solve such a problem of the wet heating system, there has been developed and provided a dry Ondol flooring having a built-in hot water pipe in a panel made of concrete, synthetic resin, or loess, or a groove or a fixing member for inserting a hot water pipe.

Most of these dry floor heating flooring systems are prefabricated heating systems, and they can be easily assembled in the field by assembling the prefabricated dry panels in the field, thereby shortening the construction period and facilitating maintenance.

In Korean Patent No. 10-0712826 (Patent Document 1), as an example of such a dry flooring flooring material, a top plate exposed to the outside and a bottom plate contacting the floor are integrally formed, and a plurality of A plurality of vertical partition plates for supporting the upper and lower plates in the longitudinal direction and dividing a plurality of flow passages into one body, And a protruding portion which protrudes to a position coinciding with the insertion groove and is insertable into the insertion groove is formed on both sides of thetouch touching, And a hose or a plug-connecting portion is formed at both sides of the connection pipe for supplying hot water to the two-touch fitting A flood board and a lid are adhered to each other by an ultrasonic welding method after the protruding portion of the lid is fitted into the insertion groove formed on both side surfaces of the flooring board, A hot water circulation floor for floor heating is proposed using a flooring board in which hot water is circulated between the connecting portions of the flooring board by a hose or a plug connecting them to each other and circulating hot water through the channels of the hot water circulation floor.

However, since the flooring (the flooring board) as in Patent Document 1 is designed such that the hot water flows in all of the plurality of flow paths formed by the plurality of vertical partitioning plates, the amount of hot water used (input) is large and the capacity of the boiler must be increased accordingly. There is a problem in that the maintenance cost increases with the increase of the flow rate, and the efficiency of heat transfer to the flooring top plate is not high because each channel is formed in an elliptical shape.

Korean Registered Patent No. 10-0712826 (2007. 7. Announcement)

In order to solve the problems inherent in the prior art, the present invention provides a heat exchanger which is excellent in durability to withstand loads and can reduce the amount of hot water used (input) And it is an object of the present invention to provide a dry Ondol flooring material which can prevent the transmission efficiency from being lowered.

According to an aspect of the present invention,

A bottom plate in the form of a plate;

An upper plate spaced apart from the upper side so as to form a space above the lower plate;

A pair of side plates interconnecting both the transverse ends of the lower plate and the upper plate;

A plurality of inclined diodes inclined in a zigzag form between the lower plate and the upper plate;

A space formed by alternating a first space of a triangular shape and a second space of an inverted triangular shape in cross section by the inclined diaphragm; / RTI >

The lower plate, the upper plate, the side plates, and the inclined diaphragm are integrally formed.

According to the dry Ondol floor material of the present invention, since the diaphragm for dividing the flow path formed in the bottom material is formed in a zigzag shape, the triangular and inverted triangles are repeatedly formed in the cross section of the flow path, so that the durability against load is excellent, The amount of hot water used (input) can be reduced, so that the capacity of the boiler can be reduced. Therefore, installation cost and maintenance cost can be reduced, and the entire surface of the upper plate of the bottom material is in direct contact with hot water. There is an advantage in that the heat loss loss can be minimized.

More specifically, the bottom material of the present invention is structurally stable because the inclined partitions are formed in a triangular structure, so that the overall durability of the bottom material with respect to the load can be improved.

In addition, since hot water flows mainly into a second space having an inverted triangular shape in cross section, it is possible to reduce the amount of hot water inflow, and there is no need to increase the capacity of the boiler, and the overload of the boiler can be blocked, It is possible to shorten the time to the heating.

That is, considering that the hot water inflow amount is directly related to the heating capacity, the floor material according to the present invention can reduce the hot water inflow and improve the heating efficiency and functional (boiler heating ability) . For the reference, the flooring material (Flooring Board) having the structure of Patent Document 1 requires about 7.9 liters of warm water per 3.3 m 3, but the floor material 100 according to the present invention requires about 5.4 liters of hot water per 3.3 m 3, It is possible to reduce the quantity of hot water considering the whole floor area considering this.

In addition, according to the present invention, it is possible to bore holes or the like at the lower end surface of the first space which is not passed through hot water, so that the hot water connector as well as the blocking member can be installed in a free manner, It can be fixed to the floor by a fixing method or the like, so that the fixability to the floor can be improved.

In addition, in the case of Patent Document 1, because the connecting port is located at both ends of the flooring material (the flooring board), it is inevitably attached to the wall of the building. When the shrinkage and expansion of the flooring material caused by cold temperature are continuously and continuously hit against the wall, There is a problem such as a leakage of water due to a shock and a congestion due to a condensation phenomenon caused by a cold crossing, and the like. On the other hand, since the present invention is free to install a hot water connection, It is possible to prevent leakage due to the impact, and when the blocking member is installed at a position far from the wall surface, it is possible to suppress the growth of the mold due to the difference in cold temperature.

Also, in the case of Patent Document 1, it is difficult to use equipment such as a taka when installing a molding. In other words, since the water flows to the wall, it is a cause of leakage due to the puncture when the construction is neglected. However, the present invention completely solves the problem and can use the equipment such as the taka and the convenience of construction can be improved.

Furthermore, in the case of Patent Document 1, a large amount of water simultaneously discharged from a plurality of flow channels due to a lack of space at the connection port causes extreme bottleneck phenomenon, resulting in a large hydraulic pressure and flow resistance, However, since the hot water connector can be installed at any position on the wide bottom plate, the connection is easy and the leakage phenomenon due to the shrinkage and expansion does not occur remarkably. Not only can it be improved, but also the hole of the connection hole is widened, so that the reduction of the hot water flow due to the bottleneck phenomenon and the problem of the water noise occurring when the connection hole is passed can be solved.

In addition, in the present invention, since the triangular structure in which water does not pass may be in a natural vacuum state, the boiler can be kept warm for a long period of time because heat is accumulated, thereby solving the problem of fast cooling which is a disadvantage of dry heating.
