Description

  The present invention relates to a steel-framed unit type residential building with a basement. Specifically, a plurality of steel frame units manufactured in advance at the factory are carried into the construction site with a large truck, etc., and one of these units is buried underground, and the remaining units are placed vertically (up and down). The present invention relates to a steel-framed unit type residential building with a basement in which a basement and a ground floor are constructed by stacking and joining.

  As a steel-framed residential building with a basement, in general, foundation work including underground excavation is performed at the construction site, and a steel column with a height to reach the top end of the building is built on the underground foundation. A steel frame is hung on a steel column and a frame structure is constructed, and then the walls, floors, ceilings, roofs, and other panels of the basement floor and the ground floor are sequentially attached to the frame structure. In addition, the mainstream is the construction of the entire site. However, such a steel-framed residential building with a basement in the on-site construction method is very large and complicated on-site construction, and requires a long construction period and a huge construction cost. Also, in densely populated areas such as the city center, the negative effects on surrounding houses such as noise and vibration associated with construction are enormous. In addition, since the columnar shape and the beam shape are projected in the room on both the basement floor and the ground floor, the indoor space is narrowed, and there is a problem that there is no freedom in the floor plan.

  As an alternative to a steel-framed residential building with a basement of such a full-site construction method, the present applicant has already proposed a unit-type residential building as shown in Japanese Patent Application No. 2001-205438. In the proposed steel-framed residential building with basement, a metal outer plate is fixed to the outside of a plurality of core steel frames, and a heat insulating layer made of in-situ foam resin is formed on the part surrounding the core steel frames and the inner surface of the outer plate The wall structure, ceiling structure, and floor structure are assembled at the factory to form a box unit with a ramen structure in the beam-to-beam direction and an earthquake-resistant panel structure in the direction of the beam (manufactured by the factory). One box unit is carried to the construction site, and one of the box units is buried underground to construct the basement, and the remaining box units are sequentially stacked on the basement box unit, and adjacent to each other vertically. Box units that are to be connected to each other by tightening the bolts with the top and bottom ends of the core material in each box unit butted between the core material steel frame and the metal outer plate It is a steel-framed unit type residential building with a basement that is built in multiple floors including the basement by fixed joining via field welding etc., in each structure of the ceiling, wall and floor of each box type unit The space between the metal outer plate and the floorboard or interior material is connected to each other to form a circulation ventilation path that surrounds the outer periphery of each unit, and the circulation ventilation paths of each unit are connected to each other by duct connection. The air in the circulation ventilation path of the box unit is configured to be capable of forced circulation in the circulation ventilation path of the box unit for the ground floor.

  The above-mentioned proposed steel-framed unit-type residential building with basement (hereinafter referred to as the previously proposed technology) by the applicant described above has very little on-site construction compared to the conventional general steel-framed residential building of the on-site construction method, The construction period can be greatly shortened and the construction cost can be reduced, and it can be constructed in a densely populated area such as the city center with almost no adverse effects on surrounding houses due to noise and vibration. In addition, since all units are manufactured at the factory, the strength and quality are stable, and the pillars and beams on each floor are made of the same material with a ramen structure in the beam-to-beam direction and a seismic panel structure in the beam direction. There is no fear of concentration of shin stress due to variations in member rigidity, etc., and it has an enormous proof stress and is also excellent in earthquake resistance. Furthermore, columnar and beam shapes are used in both the basement and ground floor. Since it does not exist in the protruding state, there is no waste of indoor space and there is freedom in floor plan and the like. In addition, by forcibly circulating the air in the circulation ventilation path in the basement unit, which is stable in the temperature range of 17 to 25 ° C. throughout the year, to the circulation ventilation path in the ground floor unit through a duct fan or the like, It has many advantages such as minimizing the temperature change of each structure in the floor unit, reducing the air conditioning (cooling / heating) load by that amount, and reducing the cost of air conditioning required to ensure comfortable living. Yes.

  However, in the basement unit, the proposed technology by the present applicant that only forcibly circulates the air in the circulation ventilation path formed around the outer periphery to the circulation ventilation path in the unit for the ground floor via a duct fan or the like. In the basement unit, as the pressure in the circulation ventilation path decreases, the temperature of the circulating air increases as the temperature gradually increases in summer and the temperature gradually decreases in winter. Changes are inevitable, and as a result, there is a limit to the reduction in air conditioning load and the resulting reduction in air conditioning costs due to the effective use of geothermal heat, which is stable throughout the year, and there remains room for improvement in this regard. It was.

  The present invention has been made in view of the above circumstances, shortening the construction period, drastically reducing the construction cost, improving the proof stress and earthquake resistance, and there is no column shape or beam shape in the room, and there is freedom in the floor plan, etc. Remarkably reduce air conditioning costs to ensure comfortable living by keeping the air conditioning load constant by wrapping not only the basement but also the entire building with geothermal heat with a stable temperature It aims to provide a steel-framed unit type residential building with a basement that can be achieved.

  In order to achieve the above object, the steel-frame unit housing with basement according to the present invention is a wall in which a metal outer plate is fixed to the outside of a plurality of core steel frames arranged in parallel at a predetermined interval on the same surface. A basement unit constructed by assembling a structure, a ceiling structure, and a floor structure in a factory to form a ramen structure in the beam-to-beam direction and an earthquake-resistant panel structure in the direction of the beam, and a wall structure and a ceiling structure in the basement unit A wall structure and ceiling structure of the same specification are assembled at the factory, and it is composed of ground floor units that are composed of a ramen structure in the beam-to-beam direction and an earthquake-resistant panel structure in the cross-beam direction. Both types of units are brought into the construction site. The basement unit is buried in the basement, the ground floor unit is stacked on the basement unit, and the basement unit and the ground floor unit are adjacent to each other. Units for upper floors are integrally constructed by welding in a state in which the end portions of the wall structures are in contact with each other, and a heat insulating layer made of in-situ foam resin is formed on the portion surrounding each core steel frame and the inner surface of the outer plate A steel-framed unit-type residential building with a basement, wherein the horizontal space under the floor between the metal outer plate and the floor plate in the floor structure of the basement unit is packed with a heat storage material having a large heat capacity, The vertical space in the wall between the metal outer plate and the wall material in the wall structure of the basement unit air after the outside air is forcedly introduced into the horizontal space below the floor and the temperature is adjusted by heat exchange with the heat storage material Ventilation passages for supplying air into the ground floor room through the vertical space in the wall between the metal outer plate and the wall material in the wall structure of the unit and the ground floor unit and exhausting to the outside are formed. It is characterized.

  According to the present invention having the above-described configuration, the construction period can be significantly shortened and the construction cost can be greatly reduced as compared with a conventional steel-framed residential building with a basement of the full-site construction method, and adverse effects on surrounding houses due to noise, vibration, etc. However, it can be constructed with almost no state. In addition, because the strength and quality have been stabilized by factory production, and the pillars and beams on each floor have a ramen structure in the inter-beam direction and an earthquake-resistant panel structure in the cross-beam direction, they have enormous proof strength and are also earthquake-resistant Also very good. In addition, since neither the basement nor the ground floor rooms have columnar or beam shapes in the room, there is freedom in floor plan, etc., and the most desirable comfortable living space as a residential building can be obtained. Has many advantages.

  Moreover, in the present invention, a thermal storage material having a large heat capacity is packed into the horizontal space under the floor between the metal outer plate and the floor plate in the floor structure of the basement unit, so that the underground thermal energy is stored in the horizontal space under the floor. After forming a heat storage layer that can sufficiently store heat, the outside air forced into the heat storage layer is immediately adjusted to the geothermal temperature or almost the geothermal temperature, and then the temperature-adjusted air is supplied to the ground floor room and exhausted. In order to keep the air conditioning (cooling / heating) load small by wrapping the entire building, including the basement, as well as the ground floor, with geothermal heat with little temperature change, and thus ensuring comfortable living There is an effect that the air conditioning cost can be significantly reduced.

  As a heat storage material in a steel-framed unit type residential building with a basement according to the present invention, any one of chestnut stone or a mixture of charcoal such as charcoal and bamboo charcoal in chestnut stone as described in claim 2 may be used. Good, but especially when using a mixture of charcoal such as charcoal and bamboo charcoal in chestnut stone, it is possible to perform humidity control, deodorization and sterilization on the outside air in addition to the temperature control. Improvements can be made.

  In addition, in the steel-framed unit type residential building with a basement according to the present invention, focusing on the fact that the place where the heat most enters and exits is an opening such as a window or a door, In the opening provided in the wall structure of the unit for use, a double layer glass in which an air layer or a vacuum layer is formed between two glasses or a vacuum layer and a heat insulating gas layer are formed inside the glass, and the inner surface radiates. By using highly insulated glass with a double metal film that suppresses heat, the heat that enters the ground floor through the opening in the summer and the heat that escapes to the outside through the opening in the winter are minimized. Although it is built, it can maintain a high thermal insulation effect, particularly enhance the comfortability of the ground floor room, and can further reduce the cost of air conditioning.

  On the other hand, the pair of left and right divided units 2u and 2u having a substantially L-shaped vertical cross section in the above-ground first floor unit 2U has a wall structure 8W and W of both divided units 2u and 2u as a wall structure in the basement unit 1U. Are stacked on the basement unit 1U so as to be located in the same plane as the bodies 7W and 7W, and the ends of the ceiling structures 8C and 8C of the two divided units 2u and 2u are joined to each other so that the vertical cross-sectional shape is substantially downwardly open. After being assembled in a letter shape, by fixing the wall material 8w and the ceiling material 8c via the base material 15 inside the core material steel frame 5 of each structure 8W, 8C, as shown in FIG. It has the vertical space part 23v in the wall with the heat insulation layer 13 and the horizontal space part 23h behind the ceiling as described above, and is connected to the vertical space part 23v in the wall at the lower part of one wall structure 7W. The air inlet 24, and Square of the wall structure first floor chamber F1 to outlet 25 connected to the intramural vertical space 23v is provided on the upper portion of 7W is construction.

  Also, the pair of left and right divided units 2u, 2u having a substantially L-shaped vertical section in the second floor unit 2U is formed on the first floor unit 2U by substantially the same means as the first floor unit 2U. After assembling in a substantially downward opening U-shape, the wall material 8w and the ceiling material 8c are fixed to the inside of the core material steel frame 5 of each structure 8W, 8C via the base material 15 as shown in FIG. Thus, like the ground floor unit 2U, the ground has the vertical space portion 23v in the wall with the heat insulating layer 13 and the horizontal space portion 23h in the wall, and the air inlet 24 and the exhaust port 25 are provided. Second floor room F2 is being constructed. In addition, on the outer surface of the metal outer plate 6 of the wall structure 8W in the above-ground first floor and second floor units 2U, an expanded metal is welded and mortar is applied or sprayed onto the rasmol base to prevent rust. Anti-corrosion treatment is applied.

  Then, as shown in FIG. 6, the basement unit 1U, the ground floor unit 2U, and the two ground floor units 2U adjacent to each other in the vertical direction are the cores of the wall structures 7W and 8W in the units 1U and 2U. Unit 1U for basement by rigidly joining the metal plate members 11, 11 fixed to the upper end portion and the lower end portion of the steel frame 5 at the site in a state where the metal plate members 11 and 11 are in contact with each other by a fillet weld 26 And two ground floor units 2U are integrally constructed.

  In addition, the basement unit 1U and the two ground floor units 2U as described above provide an integrated frame, and the underfloor horizontal space 20h in the floor structure 7F and the vertical space in the wall in the wall structure 7W of the basement unit 1U. The portion 20v and the vertical space portion 23v in the wall structure 8W of the wall structure 8W of the ground floor and second floor unit 2U and the ceiling back horizontal space portion 23h in the ceiling structure 8C are connected in an airtight state. The temperature is adjusted by heat exchange between the outside air 0A forcibly introduced into the underfloor horizontal space portion 20h in the floor structure 7F of the basement unit 1U via the fan 21 and the pipe 22, and the chestnut stone 22 in the underfloor horizontal space portion 20h. In addition, the air after being conditioned, deodorized and sterilized by contact with the carbide 16 is in the wall structure 7W of the basement unit 1U. It is circulated through the inner vertical space portion 20v to the vertical wall portion 23v in the wall structure 8W of the wall structure 8W of the ground floor and second floor units 2U and the ceiling horizontal space portion 23h in the ceiling structure 8C, and a part of the circulating air is blown into the air. Ventilation passages are formed through the outlet 24 to blow into the ground first floor room F1 and the ground second floor room F2 and exhaust to the outside through the exhaust port 25.

  The unit-type steel-framed two-story residential building with basement constructed as described above has the same specifications and the same specifications using the same standardized unit as the single basement unit 1U manufactured at the factory using standardized members. It is only necessary to carry out unit joining work by bringing two ground floor units 2U manufactured to the structure into a house construction site via a large truck, etc., and then stacking and fixing them together. Compared to conventional multi-storey steel buildings built by construction, the construction period can be significantly shortened and construction costs can be greatly reduced, and it can be built with almost no adverse effects on surrounding housing due to noise, vibration, etc. It is.

  In addition, the strength and quality of each unit 1U, 2U are stabilized by factory production, and the pillars and beams of each floor have a ramen structure in the beam-to-beam direction and an earthquake-resistant panel structure in the direction of the beam. Moreover, since the ground room unit 2U is firmly supported by the ground with the base unit 1U as a deep foundation, it has excellent earthquake resistance and durability, such as minimizing the shaking of the ground room unit 2U when an earthquake occurs. It is possible to secure. Furthermore, since neither the basement BR nor the ground floor rooms F1 and F2 have a columnar shape or a beam shape in the room, the floor plan and the like are free, and a comfortable living space that is most desirable as a residential building can be obtained.

  Furthermore, the basement unit 1U and the ground floor unit 2U have an integrated structure by on-site fillet welding 12 in a state in which the metal plate members 11 and 11 fixed to the core steel frames 5 and 5 are in contact with each other. Therefore, geothermal heat with little temperature change throughout the year is transmitted to the ground floor units 2U through the core steel frames 5 and 5 and the metal outer plates 6 and 6 excellent in heat conduction, and the inner wall surface temperature of these ground floor units 2U. Is always kept at geothermal temperature (17-25 ° C.) or near geothermal temperature.

  In addition, the underfloor horizontal space portion 20h of the floor structure 7F of the basement unit 1U is filled with chestnut 22 having a large heat capacity, and the underfloor horizontal space portion 20h has underground heat whose temperature is stable throughout the year. Since the energy is sufficiently stored, the outside air OA is forcibly introduced into the heat storage layer of the geothermal energy, and the outside air OA and the Kuriishi 22 are subjected to heat exchange, so that the introduced outside air OA is immediately heated to the geothermal temperature or almost the geothermal temperature. The temperature-adjusted air, that is, the air that is cooler than the outside air in summer and the air that is warmer than the outside air in winter passes through the vertical space 20v in the wall in the wall structure 7W of the basement unit 1U, and the first and second floors above the ground. And circulating to the vertical space 23v in the wall in the wall structure 8W of the unit 2U and the horizontal horizontal space 23h in the ceiling structure 8C, Part of the circulating air is blown supplied from the air blowing port 24 to the first floor chambers F1 and second floor chamber F2, and will be exhausted to the outside from the exhaust port 25 of the.

  As a result, not only the basement BR, but also the entire building including the ground floor rooms F1 and F2 can be wrapped with geothermal heat with little temperature change to keep the air-conditioning (cooling / heating) load small. It is possible to significantly reduce the cost of air conditioning to ensure.

  In particular, as in the above embodiment, by filling the underfloor horizontal space portion 20h of the floor structure 7F of the basement unit 1U with carbide 16 such as charcoal, bamboo charcoal, ceramic charcoal, etc. in a mixed state with chestnut 22 having a large heat capacity. In addition to the temperature control effect of adjusting the outside air to the geothermal temperature or almost the geothermal temperature, the humidity control effect and the deodorizing / sterilizing effect on the outside air can be performed at the same time, so that the comfortability can be further improved.

  Further, as an opening 27 (see FIG. 1) such as a window provided in the wall structure 8W of the ground floor and second floor unit 2U, a plurality of glasses or glasses in which a sealed air layer or a vacuum layer is formed between two glasses. By using a highly heat-insulating glass 28 in which a vacuum layer and a heat insulating gas layer such as argon are formed inside and a metal film that suppresses radiant heat is doubled, a ground floor room is formed through an opening 27 in summer. It is possible to minimize the heat that enters the 1F and 2F and the heat that escapes to the outside through the opening 27 in the winter, and the inside and outside due to the presence of an air layer in the wall vertical space 23v in the wall structure 8W. Combined with the reduction of the heat transmissibility in the direction, the entire building is steel frame, but maintains a high thermal insulation effect, especially enhances the comfort in the ground floor rooms 1F and 2F, and air conditioning costs More of It can be reduced.

  Further, as shown in the above-described embodiment, the ground floor unit 2U is not box-shaped, but a pair of substantially L-shaped divided units 2u, 2u obtained by dividing a U-shape whose longitudinal cross-sectional shape is substantially downwardly opened left and right. When the above-mentioned ground floor units 2U are sequentially stacked on the basement unit 1U to construct a multi-storey residential building with a basement, the ceiling structure 7C of the basement unit 1U is replaced with the ground floor unit 2U. In addition, the ceiling structure 8C of the ground floor unit 2U can be used as the floor structure of the ground floor unit 2U. Therefore, material waste and excessive strength due to the double structure It is possible to reduce the production cost of the unit 2U, and consequently the construction cost of the entire residential building, by eliminating the occurrence of the portion.

  At the same time, the two ground floor units 2U are composed of a pair of left and right divided units 2u and 2u that are substantially L-shaped in vertical cross-sectional shape, so that the limit of transportation when carrying on a loading platform such as a truck is increased. It is possible to arbitrarily set the overall height of the ground floor units 2U without being restricted by the size (generally 2900 mm). As a result, a comfortable and open living space with a high ceiling height can be obtained. Obtainable. Furthermore, when two ground floor units 2U are loaded and transported on a loading platform such as a truck, a plurality of substantially L-shaped divided units 2u and 2u are stacked to reduce the required loading space during transportation. The transportation cost can be significantly reduced by half.

  In the above embodiment, the basement unit 1U has been described as being composed of a pair of left and right divided units 1u, 1u having a substantially U-shaped longitudinal section. For example, if it is set within 2900 mm), it may be configured as a single unit having a substantially cross-sectional shape of the longitudinal section, and the ground floor unit 2U has a substantially L-shaped longitudinal section. Although what was comprised from the left-right paired division | segmentation unit 2u and 2u was demonstrated, if it is a case where the unit total height is set within the limit height (generally 2900 mm) of conveyance, a longitudinal cross-sectional shape is substantially downward open | released You may comprise in a U-shaped single unit.

  Further, as shown in the above embodiment, the basement unit 1U is installed on the reinforced concrete solid foundation 3 and is connected to the reinforced concrete solid foundation 3 on the outer periphery of the underground portion of the wall structure 7W. By covering and forming the unreinforced concrete wall 10, it is possible to ensure the anticorrosion and anticorrosion performance for the entire basement unit 1U by simple on-site construction, and economically improve the durability of the entire building. Can do.
