Abstract

PURPOSE:To dispense with heating equipment by employing a convection heating system, by a method wherein a power source is connected to reinforcing bars in the reinforced concrete building and an electric current is supplied to the reinforcing bars so that the reinforcing bars act as heat generating bodies, the concrete layer acts as a heat storage body and the concrete building acts as a heat dissipating body. CONSTITUTION:The outer wall 1a, the roof slide 1b and the basic floor slab 1c of the multistoried building 1 for group houses are each made of an internal reinforced concrete layer 2, an intermediate heat insulating layer 3 and an external facing later 4. The mesh bars 5 and the main bars 6 of the reinforced concrete layer 2 are connected to a power source 8 through a control device 7 which is capable of controlling the electric current flowing through the mesh bars 5 through a command signal from a command device 9. As a result, the mesh bars 5 acts as the heat generating bodies, the concrete layer enclosing the mesh bars acts as the heat storage body and the main bars function as conductive wires so that the heat stored by the concrete layer does not escape outside but is dissipated as radiant heat.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heating system suitable for reinforced concrete buildings, particularly high-rise large-scale housing complexes.

Conventional heating methods include: 1. For example, a gas stove directly introduces fuel gas into the room, burns it, and exchanges all of the combustion heat with the room air to make the room air-neutral. Alternatively, hot water is produced in a boiler and the heated water is heated. A hot water heating method that supplies heat to the radiator in each room through piping to warm the room, or a pump air conditioner installed in each room to absorb heat from the outside air and exchange heat with the indoor air for heating. There are many methods, but all of these require special equipment for heating, and the equipment costs are extremely high in large-scale high-rise apartment buildings (and most of them are Since this is a convection type of heating, heat loss due to ventilation is large, temperature distribution is poor, and the perceived temperature is low compared to the room temperature.

Furthermore, heating methods that use energy sources fc such as gas and oil have the disadvantage that various measures must be taken to ensure safety.

The purpose of the present invention is to eliminate these drawbacks and provide a heating device that does not require the installation of a heating radiator or the like.The main feature of the present invention is to connect a power source to the reinforcing bars of a reinforced concrete structure and apply current to the heating device. Along with forming the reinforcing steel into a heating element,
The concrete surrounding the reinforcing bars is formed into a heat storage body, and the frame is configured as a heat radiating body.

An embodiment of the present invention will be described below with reference to the drawings.

(1) shows the frame of a high-rise apartment building, and the outer walls (1a), roof slab (1b), and foundation floor slab (IC) of the frame (1) are the inner reinforced concrete layer (2) as shown in the second figure. ), the middle insulation layer (3), and the outer cladding layer (
4), and the mesh reinforcements (5) and main reinforcements (6) of the reinforced concrete layer (2) are controlled by a control device (
7) to the power supply (8). Hard, control device (7
) is composed of a power transistor, and the current flowing through the mesh muscle (5) is controlled by a command signal from a command device 19), which is composed of, for example, a microcombination controller.

The outside temperature and weather conditions are displayed on the Kagute command device (9).

A calculation and learning function is provided to generate a predetermined signal based on time, etc., and a predetermined current is applied to the mesh muscle (5) etc. via the control device (7) according to the command signal from the command device (9). flows. According to this current, meshus muscle (5)
acts mainly as a heating element, and the surrounding concrete D) (101 is heat stored. That is, the concrete D
I acts as a heat storage body. The main reinforcement (61Fi) mainly functions as a conductor that leads the current to the mesh reinforcement (5).The accumulated heat does not escape to the outside through the insulation layer (31VC), but instead circulates inside and is dissipated as radiant heat.

As shown in Figure 1, it is certain that in the case of the apartment building IC, 1, even the residences near the middle area are indirectly heated by the heat from the surrounding area, and there is almost no need for individual heating. being admired.

Here are the exterior walls and roof slabs of the surrounding area of the apartment complex.

As mentioned above, by using panel coatings with heat dissipation pipes embedded in the foundation floor slab, there is almost no need for individual heating in residences near the middle area.

In the above embodiment, the present invention is applied to an apartment complex, but the present invention is not limited to this, and can be applied to, for example, a single-family house,
The bacteria may be placed in schools, assembly halls, physical education buildings, hotels, etc. As described above, according to the present invention, a current is passed through the reinforcing bars of a reinforced concrete frame to form the reinforcing bars into a heat generating body, and the concrete surrounding the reinforcing bars is formed into a heat storage body, thereby configuring the frame as a heat radiating body. ,
Since we adopted a radiant heating system, there is no need for a radiator for heating, which greatly reduces equipment costs, and allows us to use the room more effectively.In addition, the temperature distribution in the room is good, making it much warmer than the actual room temperature. It has a high perceived temperature and humidity, and since the heat capacity of the concrete is used for heat storage, its heat storage effect is good, the room temperature is highly stable, it allows the use of electricity late at night, and it is highly safe.
