(point of view)
The recent demand for housing construction has not only dropped due to the economy, but many owners who need housing have moved away from the attitudes left by the contractors. Purchasing has also become more cautious because it begins to have clear principles and claims in terms of structure and function, and has been fully assessed based on those principles and claims, so in the housing industry, It is foreseen that these home owners cannot be persuaded only by the contents of the house that have the illusion that a comfortable life can be realized by incorporating the prettiness and state-of-the-art equipment until then, structural strength and economy Of course, various functional measures necessary to realize a comfortable life, as well as sex, are forced to be reviewed more than before, and various developments and research are being promoted in each direction to realize that. It has been.

    For example, heating and cooling measures that are one of the important factors in maintaining the comfort of homes, especially in the mountainous areas of Tohoku, North Kanto, and Honshu, are not so cold as in Hokkaido. For winter heating measures in areas that have been dealt with inadequately, in addition to spending expensive expenses to make it a highly airtight and highly heat-insulating structure like that around, expensive equipment is incorporated. With measures that include centralized heating and cooling, and the economic burden is imposed not only on construction costs but also on maintenance costs, it cannot be said that it has been able to cope with the demands in the recent severe economic environment, It is expected that how to give consideration to the construction cost, especially the maintenance cost, will become a very important issue in future home construction.

(Conventional technology)
In order to deal with these issues, incentives for solar houses, including public subsidies, have begun to be implemented, but in reality, in addition to excessive initial investment, there is a problem of bad weather in the winter period. Therefore, this system is not necessarily suitable for areas that require heating, and is not widely used. Therefore, in these areas that need improvement, it is currently the most practical energy source. Heating system using kerosene that is used, but rather than using local fan heaters or clean heaters, etc., it is more efficient to use hot air heaters that can be obtained at extremely low prices as a heat source The present applicant and the inventor have already proposed a heating system based on a new method for heating automatically.

It has been developed and put into practice as JP-A-9-250788 “Building floor heating system and floor structure panel therefor”, and is used as a so-called hot air heater on the floor of a predetermined room. Rather than deferring, a predetermined space is provided in the wall adjacent to the room and deferred, and part or all of the warm air is guided to the warm air space prepared in advance under the floor of the room. Heating from the floor, that is, floor heating, far more economically and ideally compared to the type with a conventional electric heater embedded in the floor and the type with piping and steaming Although it has been confirmed that it can be realized, for the purpose of fan heaters and clean heaters with a limited amount of heat, the warm air of the local heater is spread as efficiently and as homogeneously as possible. There is always the issue of how to make it reach, and for each house with various layouts, we will devise the structure of the warm air feed space and the arrangement of the conduits so far. In some cases, there was a need for it, and even when it was devised that way, it would encounter a scene where the heating effect could not be obtained as planned.

(Awareness of problems)
Based on the knowledge gained from the past development and practical application of the same type of heating system in view of the above situation, it supports all types of floor structures, even if the flooring is different for each house. An effective solution that enables floor heating to be performed evenly is necessary, and the existing systems that have already been realized are taken over as much as possible, and the thermal energy efficiency that could not be realized by those before It was necessary to develop and research new technical means to make it available.

(Object of invention)
Therefore, in the present invention, even if the floor structure for each of the substantially entire area of the unit section plane surrounded by the bases arranged according to the room unit section of the building changes, the warm air feeding space that is secured there As a result of repeated trial and error, many trial experiments have been repeated as to whether it is possible to realize a new floor structure so that warm air spreads through the inner corners. The completion has been seen, and in the following, details of the configuration will be shown while taking up typical examples.

(Structure of the invention)
The floor heating assembly according to the present invention basically has the following configuration. That is, when forming a floor structure of a building from an upper floor structure part in which an upper floor base plate is stretched and a lower floor structure part in which a lower floor base plate is stretched at a predetermined interval below the upper floor structure part, This is a floor heating floor assembly having a gist of a configuration in which a thin film material is stretched between the lower surfaces of at least joists or joist-equivalent members arranged at predetermined intervals as the structural members of the section.

    The floor heating floor assembly of this basic configuration, in other words, an upper floor structure part in which an upper floor base plate is stretched, and a lower floor structure part in which a lower floor base plate is stretched at a predetermined interval below the upper floor structure part. When forming a floor assembly of a building from, it is assumed that a thin film material is stretched between at least the joists or the joist equivalent members arranged at predetermined intervals as structural members of the upper floor structure part, In the warm air feed space secured between the upper floor structure part and the lower floor structure part, the joist or the joist equivalent member which is a structural member of the upper floor structure part is directly exposed, and the same space is fed as an air blowing path. It can be said that it is a floor heating floor assembly configured to prevent an obstacle to the flow of warm air.

    If the basic structure of the present invention described above is more specifically expressed, an upper floor base plate is stretched by using joists or joists equivalent members arranged at predetermined intervals as at least a support portion, and the upper floor is appropriately finished. When forming a floor structure of a building from an upper floor structure part designed to be a floor surface and a lower floor structure part having a lower floor base plate stretched at a predetermined interval below the upper floor structure part, As a structural member, a floor heating floor assembly in which a thin film material is stretched between the lower surfaces of at least joists or joist-equivalent members arranged at predetermined intervals as structural members.

    The floor heating floor assembly according to the present invention having the above-described configuration has an upper floor structure portion and a predetermined portion below the upper floor structure portion, regardless of whether the frame structure is a shaft assembly structure or various panel structures. Lower surface of joist or joist equivalent member arranged at predetermined intervals as the structural member of the upper floor structure part when forming the floor assembly of the building from the lower floor structure part with the lower floor base plate stretched at intervals Because the thin film material is stretched across each other, the warm air feed space secured between the upper floor structure part and the lower floor structure part of this floor assembly (in some cases also applied to the cold air feed space) The same applies to the following), such as a fan heater or the like, which is used exclusively for local heating, such as a heater that is not necessarily sufficient in heat, and is sent by using warm air from a heat source. The joist or the joist equivalent member, which is the structural member of the upper floor structure part, is not directly exposed to the warm air feed space until it reaches a place far away from the sent location, and no uneven surface is formed at all. The warm air sent as the air flow path is weakened by colliding with the structural members of the upper floor structure part, etc., and does not reach the back part, or even if it reaches, the amount of heat is lost or lost in the middle The excellent feature of being able to solve the biggest inconvenience in achieving unparalleled floor heating, such as disrupting the flow of warm air. Will be demonstrated.

    Moreover, the thin film material employed in the floor heating floor assembly of the present invention is at least a joist or joist equivalent member (in some cases, a joist or joist equivalent member) arranged at predetermined intervals as a structural member of the upper floor structure. It has a material strength that allows it to stretch between the lower surfaces of the pulling or large pulling equivalent member), and if it has been used up to now, it will be exposed in the warm air feed space to form an uneven surface. If it can fulfill the function of flattening the uneven surface by the structural member of the heel or having a property close to that, it has air permeability such as Japanese paper, non-woven fabric, perforated sheet, mesh body, etc., regardless of the material. The material is a single layer or laminated appropriately in multiple layers, or a non-breathable material such as plastic film, oil paper, various coated papers, etc. Or, a breathable material such as Japanese paper, non-woven fabric, perforated sheet or mesh body and a non-breathable material such as plastic film, oil paper, various coated papers, etc. are laminated in multiple layers as appropriate. Since it is possible to use almost all thin film materials, including those consisting of materials typified by, etc., the adoption and implementation of floor heating floor assembly can be realized economically and easily. In addition, a practical effect can be obtained.

    As a result, inconveniences such as resistance to airflow movement in the warm air feed space configured between the upper and lower floor structure parts and the occurrence of complicated turbulence are almost eliminated. When sending warm air (or cold air) and air-conditioning the room above it, the air flow can be uniformly and quickly diffused throughout the space without loss, and heat energy can be transferred very efficiently. Therefore, the performance of the heat energy generation source can be relatively small. For example, in a house adopting the floor heating floor assembly of the present invention as floor heating in a cold region, the heat energy As a generation source, oil fan heaters, hot water room heaters, oil heaters with fans, etc., which are direct heaters for general households, can obtain sufficient effects and have a large burden. It is quite useful to save energy costs have a large advantage is obtained that leads to possible to eliminate even a little wasteful consumption of fossil energy and thus.

    In implementing the floor heating floor assembly of the present invention having the configuration as described above, the best or desirable mode will be described. First, in the case of a building, especially a house with a wooden frame structure, etc., the foundation is usually turned for each room unit in a plane arrangement, and the foundation is used as a support part, which corresponds to a frame such as a column, a stud, or a brace. The base is equivalent to the section that creates the room, and the base is surrounded by these bases. The range is the unit partition plane, so the unit partition plane naturally changes in size depending on the size of the room, such as whether the target room is between eight tatami mats or ten tatami mats. Needless to say, any of them corresponds to the unit partition plane of the present invention. If it is not a wooden frame structure, such as a panel structure, etc., and the room section is not necessarily based on the base, the plane section surrounded by the wall that partitions each room As described above, the section constituting the room is handled as a unit section plane, and is not always determined only by the presence or absence of the foundation.

    And in the unit partition plane, in the ordinary wooden frame structure, the forehead for carrying out the joist as the floor foundation is set horizontally at intervals of 90 cm. In the floor foundation structure of the present invention, too. However, it is premised on the use of the large fork arranged at predetermined intervals as a support structure for the floor foundation. For example, other than the wooden frame structure, for example, a panel construction method or 2 × 4 or 2 × In the case of 6 construction methods, etc., which do not employ large drawing, the structural floor panel itself in those methods is regarded as the previous large drawing equivalent member, and the load from the floor is transmitted to the structure. A support structure is used.

    Thus, when the large drawing or the equivalent member in the whole area of the unit partition plane is attached, the joists are spanned in parallel with each other at a predetermined interval, for example, an interval of 30 cm or 45 cm, in a direction perpendicular to them. From the lower floor structure, plywood and other lower floor foundation plates are stretched to form a lower floor structure section, which is about 10 to 30 cm above the lower floor foundation board (this range is the height of the eaves of the target building such as a house It depends on the scale of the floor heating and the brain power of the heat source such as local heaters, etc., so this is a temporary measure.) Japanese Patent No. 3432200 entitled “Floor Underground Structure and Float for It” which has been developed by the present applicant or inventor, depending on the member and joists As a means according to the invention of the "Jeitakan" invention or Japanese Patent Application No. 2000-189864 "Double underfloor structure" invention, the upper floor structure part is incorporated to form the floor assembly in the entire area of the building unit section plane. It is.

    In the present invention, when forming this floor assembly, the space sandwiched between the upper floor structure portion and the lower floor structure portion as it is is not used as a warm air feed space, but as a structural member of the upper floor structure portion. In the warm air feeding space secured between the upper floor structure part and the lower floor structure part, the thin film material is stretched around at least the joists or the joist equivalent members arranged at intervals. It is necessary to prevent the joist or joist equivalent member that is a structural member of the floor structure part from being directly exposed and obstructing the flow of warm air that is sent as the air flow path, but the thin film material at that time In particular, there is no particular requirement if the joist or the joist equivalent member, which is a structural member of the upper floor structure, can fulfill the function of preventing direct exposure to the warm air feed space. Is not limited, taking into account its material strength, handleability, economics, etc., and representative examples thereof include, for example, a single layer of a breathable material such as Japanese paper, nonwoven fabric, perforated sheet, mesh body, etc. When laminated in multiple layers, non-breathable material such as plastic film, oil paper, various coated papers, etc., or laminated with multiple layers as appropriate, or Japanese paper, non-woven fabric, perforated sheet Most of the materials including those that cannot be illustrated, such as those in which a breathable material such as a mesh body and a non-breathable material such as plastic film, oil paper, and various coated papers are laminated in an appropriate combination. Any thin film material can be used.

    In the warm air feed space in the building floor assembly according to the present invention thus realized, at least the joist or the joist equivalent member is not exposed, it is simply the large pull or the equivalent member, the minimum necessary cross-sectional shape, and the necessary minimum Only a plurality of bundles of small cross-sections that are restricted to the number of the timbers will become a forested space, realizing a floor heating floor assembly that minimizes the influence of horizontal airflow movement, and warm air from any direction In other words, even if the arrangement of the heat source is restricted due to the floor plan, it has the advantage of providing a very convenient warm air supply that does not affect the floor heating efficiency at all It is not known at all from the living room space side in the unit partition plane that the double-layered floor heating assembly of the present invention is formed. Therefore, it is considered that the floor base plate is stretched as usual, and therefore, the floor material corresponding to the room planned for the unit compartment plane, for example, if it is a Japanese-style room, A tatami mat is spread, and if it is a western space, a flooring material or the like is used for a known western flooring finish.

    Further, if necessary, the surface of each upper and lower base plate (that is, the upper base plate aggregate in the upper layer) that faces the warm air feed space formed by the floor heating floor assembly having a double structure according to the present invention. Heat reflection function layers such as aluminum foil and aluminum vapor deposition sheet are formed on the lower surface and the lower base plate, or special plywood such as heat storage plywood is used for the upper and lower base plates themselves. It can be said that it is desirable to consider the smooth surface function and the heat insulation function as well as to make it as advantageous as possible for lightening in consideration of handling. Hereinafter, specific examples will be taken and explanation will be added so that the configuration of the floor heating floor assembly of the present invention described above can be grasped more clearly.

    The main part longitudinal cross-sectional view shown in FIG. 1 shows the most basic structure of the floor heating set according to the present invention, and is constructed on the site for each predetermined unit section plane of the building. This is a representative case study. The foundation 1 is placed on the foundation B of the building and fixed by anchor bolts B1, and columns 2, 2,... Are erected at predetermined locations according to the arrangement of openings, bearing walls, etc. The section surrounded by the bases 1, 1,... Becomes a unit partition plane constituting one room in the building, and the parallel bases 1, 1 are supported at both ends in the unit partition plane. As shown in the figure, the large-drawings 3, 3,... In the figure, B2 indicates a bundle as a basic structure that supports the large pull.

    Since there is no fear of receiving a load as a surface on the upper drawing 3, 3,... In this foundation surrounding structure, the aggregate (a joist equivalent member) 81 having a smaller cross section than the commonly used joist is used. , 81,... Are spread over 45 cm intervals, and a lower base plate 8 is stretched thereon to form a lower floor structure, and about 20 cm above the lower base plate 8 of the lower floor structure. In this position, as a structural member that supports the load as a direct surface, this time as a floor facing the room, a joist equivalent member corresponding to a half-cut section such as the base 1 or the overhang 3 (the base like the so-called joist) , 91, 91,... Are arranged in the same arrangement as the aggregates (equivalent to joists) 81, 81,... , 9 mm round steel at 90 cm intervals for each joist equivalent member 91 By standing up and supporting the bundles of thin cross-sections 6, 6,... Made of, an upper base plate 9 such as a plywood is stretched on the upper surface to form an upper floor structure portion. A floor assembly in which the inside is formed in a warm air feeding space.

At that time, if warm air is sent in with the structure of the floor assembly as it is, the joists equivalent members 91, 91,... Of the upper floor structure portion of the floor assembly are suspended in the warm air feed space. As a result, the flow of warm air is hindered due to the uneven space, and there is a high possibility that the warm air will not be supplied uniformly throughout the warm air feeding space. Therefore, as an effective means for eliminating such harmful effects, as the thin film material 5 of the present invention, a plastic film having a thickness of about 0.8 mm, which is easily available and inexpensive, is applied to the joist equivalent members 91, 91,. It is made to stretch between the lower surfaces of. In the figure, 51 is a pressing material for fixing the said plastic film (thin film material 5) to the surrounding wall 7 of the warm air feeding space S, and a stapler stop (in the figure, the indication is shown) (Omitted)
By doing so, the floor heating floor assembly of the present invention having a warm air feed space which prevents the middle of the plastic film (thin film material 5) from sagging and has a flat surface on both the upper and lower sides is realized.

(Effect of Example)
Thus, the floor heating floor assembly of the present invention, which has a double structure with an interval of about 20 cm in the unit partition plane, is used as a heat source for the convenience of the floor plan of the house, etc., as described above. Regardless of the location where the fan heater is placed, even if the location is determined in any direction with respect to the target room, warm air can be warmed from any direction on the peripheral wall 7 corresponding to it. Irregularities of the joist equivalent members 91, 91,..., Etc., which are structural members, are flat with a plastic film (thin film material 5), which can be sent into the warm air feeding space S and from which direction the warm air is sent. Therefore, it will flow smoothly without being bothered by the joist equivalent members 91, 91,... Efficiently and economically assures the effect that it can be supplied almost evenly at any time without losing the heat energy of the warm air in the middle or stagnation in one place. It will have a great effect of enabling real floor heating.

(Summary)
As described above, the floor heating assembly according to the present invention enables the intended purpose to be generally achieved by the new configuration, and the construction can be carried out simply, surely and efficiently, and the finished finish. Under the floor, an effective warm air feeding space can be reliably secured, and it can be used for various applications such as air conditioning. An excellent building floor can be realized, and a sufficient heating effect can be obtained even with an inexpensive heat source, which is particularly useful as a residential floor heating located in a cold district, etc. It is expected that it will be widely adopted, developed and greatly expanded from the housing-related industry, where efficient housing is strongly demanded, and it has been widely adopted by the general public who lives in it.
