Description

[Technical Field]

[0001] The present disclosure relates to a base member set, a partition support member, and a heating and cooling system, and more particularly to a base member set, a partition support member, and a heating and cooling system suitable for heating and cooling by radiation. [Background technology]

[0002] There is a steel floor in which a floor surface is formed by arranging multiple steel joists in parallel on top of the joists so that they cross the joists, and then laying flooring materials on top of the joists. The following is an example of a system that uses such a steel floor to heat and cool the space above the steel floor. This system forms air passages inside the steel joists and joists, flows temperature-controlled air through these internal air passages, and transfers the cold or hot heat of the temperature-controlled air to the flooring, thereby cooling or heating using radiant heat from the flooring (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-112566 Summary of the Invention [Problem to be solved by the invention]

[0004] The steel floor described in Patent Document 1 has a hat-shaped cross section of the joist steel. In other words, one of the four sides of the joist steel is an open surface. Therefore, in order to create an air flow path inside the joist steel, it is necessary to seal it with aluminum tape or iron plates, which increases the burden of construction.

[0005] In view of the above-mentioned problems, the present disclosure relates to providing a base member set, a partition support member, and a heating and cooling system that can distribute a heat medium for radiation while suppressing an increase in the burden during construction. [Means for solving the problem]

[0006] The base member set according to the first aspect of the present disclosure comprises a first square steel pipe that is placed in contact with or close to a partition material that forms the outline of a space to be cooled and heated from the back side of the space to be cooled and heated, the first square steel pipe having an opposing surface that is the surface on which the partition material will be present, a pair of adjacent surfaces adjacent to the opposing surface, and an opposing surface that is the surface opposite to the opposing surface, and a second square steel pipe that is in contact with the opposing surface and is placed so as to intersect with the first square steel pipe, and the first square steel pipe and the second square steel pipe are arranged so as to intersect with each other. A communication hole connecting the inside of the first square steel pipe and the inside of the second square steel pipe is formed in each of the first square steel pipe and the second square steel pipe at a position where they come into contact with each other, an inlet for a gaseous heat transfer medium is formed in at least one of the first square steel pipe and the second square steel pipe, and the first square steel pipe has a plurality of outlets for the gaseous heat transfer medium formed on the opposing surface at predetermined intervals in the extension direction of the first square steel pipe, extending in a direction intersecting the extension direction of the first square steel pipe, and the outlets extend to the adjacent surface.

[0007] By configuring it in this manner, since a first square steel pipe and a second square steel pipe are used, there is no need to subsequently seal the opening side to form a culvert that serves as a flow path for the gaseous heat transfer medium, and a configuration for distributing the gaseous heat transfer medium can be easily constructed.

[0008] In addition, a base material set according to a second aspect of the present disclosure is a base material set according to the first aspect of the present disclosure, which includes a jet unit attached to the outlet, and the jet unit has a long, thin flat plate having an opening with an area smaller than the outlet, and a pair of side plates rising in the same direction from each of a pair of longitudinal edges of the flat plate, and the jet unit is configured so that when the opening is attached to the outlet at a position encompassed by the outlet, the flat plate and the pair of side plates protrude from the first square steel pipe in the direction in which the outlet extends.

[0009] With this configuration, the gaseous heat transfer medium flowing out from the outlet is guided by the flat plate and the pair of side plates, so that the flowing out gaseous heat transfer medium can be made directional and reach a greater distance.

[0010] Furthermore, a base material set according to a third aspect of the present disclosure is a base material set according to the second aspect of the present disclosure, wherein the jet unit has pleats extending along the side plates between a pair of the side plates.

[0011] With this configuration, the gaseous heat transfer medium that is guided by the flat plate and the pair of side plates and flows out is straightened by the pleats, and the width of the flowing gaseous heat transfer medium can be maintained.

[0012] Furthermore, a base material set relating to a fourth aspect of the present disclosure is a base material set relating to the second aspect of the present disclosure, wherein the jet unit is configured so that the distance between the pair of side plates becomes shorter as it moves away from the first square steel pipe, and has pleats that rise from the flat plate between the pair of side plates, and the pleats protrude from the flat plate in a direction away from the first square steel pipe.

[0013] With this configuration, the flow rate of the gaseous heat transfer medium that flows out while being guided by the flat plate and the pair of side plates increases, and the travel distance of the flowing gaseous heat transfer medium can be extended.

[0014] In addition, a base material set relating to a fifth aspect of the present disclosure is a base material set relating to any one of the first to fourth aspects of the present disclosure, comprising a partition plate that separates at least one of the inlet space facing the inlet and the outlet space facing the outlet from a rear space on the back side of the space to be heated or cooled, which is a space in which the first square steel pipe and the second square steel pipe are installed, and a partition support member attached to the first square steel pipe and supporting the partition plate, wherein the partition support member has a concave piece that wraps around the opposite surface and a portion of the pair of adjacent surfaces on the opposite surface side of the outlet, an outflow support piece connected to the concave piece and extending in a direction away from the pair of adjacent surfaces, and an inflow support piece connected to the concave piece and the outflow support piece and extending in a direction away from the opposite surface.

[0015] With this configuration, by appropriately dividing the rear space with a partition plate, it is possible to form an inflow space that functions as an underfloor chamber, and also to form an outflow space that promotes heat transfer from the gaseous heat transfer medium to the partition material. In addition, since the partition support member is provided, it is possible to support the partition plate for forming the inflow space and / or outflow space with a simple configuration.

[0016] In addition, a partition support member according to a sixth aspect of the present disclosure is a member that is attached to a square steel pipe, and when attached to the square steel pipe, comprises a concave piece that wraps around a first surface of the square steel pipe and a pair of second surfaces adjacent to the first surface, an outflow support piece that is connected to the concave piece and extends in a direction away from the pair of second surfaces, and an inflow support piece that is connected to the concave piece and the outflow support piece and extends in a direction away from the first surface.

[0017] With this configuration, by fixing the concave piece to the square steel pipe, the member can be supported by at least one of the outflow support piece and the inflow support piece.

[0018] In addition, a heating and cooling system according to a seventh aspect of the present disclosure includes a base material set according to any one of the first to fifth aspects of the present disclosure, and a temperature regulator that adjusts the temperature of the gaseous heat transfer medium flowing in from the inlet.

[0019] With this configuration, the gaseous heat transfer medium that flows in through the inlet can be discharged from the outlet with its temperature adjusted, and the heat contained in the gaseous heat transfer medium can be efficiently transferred to the partition material to heat or cool the space to be cooled or heated. [Effects of the Invention]

[0020] According to the present disclosure, by using a first square steel pipe and a second square steel pipe, it is not necessary to subsequently seal the opening side to form a culvert that serves as a flow path for the gaseous heat transfer medium, and a configuration for distributing the gaseous heat transfer medium can be easily constructed.

DETAILED DESCRIPTION OF THE INVENTION

[0022] Hereinafter, an embodiment will be described with reference to the drawings. In the drawings, identical or similar reference numerals are used to designate identical or corresponding components, and redundant explanations will be omitted.

[0023] With reference to the drawings, a base member set 1 and a heating and cooling system 100 according to one embodiment will be described. FIG. 1 is a perspective view showing the schematic configuration of the heating and cooling system 100 including the base member set 1. The heating and cooling system 100 is a system that primarily cools or heats a space R (hereinafter referred to as the "heated and cooled space R") that is the target of cooling or heating (hereinafter referred to as "heating and cooling"). More specifically, the heating and cooling system 100 is a system that cools or heats a partition material that forms the outline of the heated and cooled space R with temperature-controlled air (gaseous heat medium), and cools or heats the heated and cooled space R using radiant heat from the cooled or heated partition material. The heating and cooling system 100 includes a base member set 1 and a temperature control device 91. In this embodiment, the base member set 1 is a set of base members that support flooring. The heating and cooling space R in which the heating and cooling system 100 is installed would normally be equipped with partitioning materials such as flooring, wall materials, and ceiling materials, but these partitioning materials are not shown in Figure 1 in order to illustrate the configuration of the base material set 1. The partial vertical cross-sectional view of the base material set 1 in Figure 2 shows flooring material F as a partitioning material. First, the configuration of the base material set 1 will be described below. The base material set 1 includes joist steel 10, joist steel 30, partition support member 50, outflow partition plate 63, and inflow partition plate 65.

[0024] The joist steel 10 is a member that supports the floor material F (see FIG. 2 ) that forms the floor surface of the heating and cooling space R, and is made of a square steel pipe (e.g., JIS G3466). Therefore, the joist steel 10 has open ends in the longitudinal direction, and the space between these ends is surrounded by steel material, functioning as a culvert. In this embodiment, the joist steel 10 is a square steel pipe with a square cross section perpendicular to the longitudinal direction. The size of the joist steel 10 can be determined taking into account the load-bearing capacity required for the floor surface of the heating and cooling space R, and for example, the square cross section may have side lengths of 40×40, 50×50, 75×75, or other sizes. Note that the joist steel 10 may be a square steel pipe with a rectangular cross section perpendicular to the longitudinal direction, depending on the use of the heating and cooling space R. The joist steel 10 is made from standard-length square steel pipes that are cut or joined as appropriate depending on the size of the heating and cooling space R. As shown in Figure 2, the joist steel 10 is placed in contact with the floor material F from the back side of the heating and cooling space R, and corresponds to a first square steel pipe. For ease of explanation, of the four side surfaces that make up the joist steel 10, the surface that contacts the floor material F will be referred to as the opposing surface 11, the two surfaces adjacent to the opposing surface 11 will be referred to as adjacent surfaces 12, and the surface opposite the opposing surface 11 will be referred to as the opposite surface 13. The opposite surface 13 is adjacent to the pair of adjacent surfaces 12 on the opposite side of the opposing surface 11.

[0025] The joist steel 10 has an outlet 15 formed on the opposing surface 11. The outlet 15 is an opening through which temperature-controlled air SA, a gaseous heat transfer medium with a controlled temperature, flows out. The outlet 15 is formed across the opposing surface 11 in a direction intersecting the longitudinal direction of the joist steel 10 (hereinafter referred to as the "intersecting direction"). In this embodiment, the outlet 15 extends in a direction perpendicular to the longitudinal direction of the joist steel 10. Since the outlet 15 is formed intersecting the opposing surface 11, it reaches the adjacent surface 12 at both ends in the intersecting direction. In other words, the outlet 15 is exposed on the adjacent surface 12. The outlet 15 is formed by making a cut in the square steel pipe at the relevant location and removing the interior surrounded by the cut. By forming the outlet 15 in this manner, when the joist steel 10 is arranged so that the entire opposing surface 11 is in contact with the back surface of the floor material F, the temperature-controlled air SA flowing out from the outlet 15 diffuses along the back surface of the floor material F while coming into contact with the back surface of the floor material F.

[0026] The size of the outlet 15 appearing on the adjacent surface 12 is preferably formed to be large enough that when the flooring material F is in contact with the entire opposing surface 11, the temperature-controlled air SA flowing out from the outlet 15 surrounded by the flooring material F and the adjacent surface 12 forms a jet. In other words, the size of the outlet 15 appearing on the adjacent surface 12 is preferably formed to have an opening area such that the flowing temperature-controlled air SA flows at a flow rate that breaks up the boundary film (an extremely thin region where a laminar flow state is maintained that exists at the phase boundary when fluids are in relative motion) formed between the flooring material F. Generally, if a boundary film where air stagnates exists between the flooring material F and the flow of the temperature-controlled air SA exists, the surface heat transfer resistance increases and the cold or hot energy contained in the temperature-controlled air SA is not efficiently transferred to the flooring material F; however, the heat transfer coefficient can be improved by breaking up the boundary film. The size of the outlet 15 appearing on the adjacent surface 12 can be, for example, about 20 mm to 40 mm in width (distance in the longitudinal direction of the joist steel 10) and about 3 mm to 6 mm in height (distance in the direction perpendicular to the opposing surface 11). In view of the above-mentioned function, the outlet 15 can be formed only on the adjacent surface 12 without being formed on the opposing surface 11, but forming it so that it traverses the opposing surface 11 and reaches the adjacent surface 12 has the advantage of making processing easier.

[0027] A plurality of outlets 15 are formed per joist steel 10. The plurality of outlets 15 are arranged at predetermined intervals in the longitudinal direction of the joist steel 10. The interval between adjacent outlets 15 is preferably set to allow the temperature-controlled air SA to come into even contact with the back surface of the flooring material F. By bringing the temperature-controlled air SA into even contact with the back surface of the flooring material F, the flooring material F can be cooled or heated evenly. The interval (center-to-center) between adjacent outlets 15 can be set to, for example, approximately 100 mm to 200 mm. In this embodiment, a plurality of joist steels 10 configured in this manner are arranged in parallel at predetermined intervals. The number of joist steels 10 may be determined depending on the size of the air-conditioning space R. The interval between adjacent joist steels 10 should be determined based on the reach distance of the temperature-controlled air SA flowing out of the outlets 15, from the viewpoint of bringing the temperature-controlled air SA into even contact with the flooring material F. On the other hand, if a specific standard exists (for example, JISA6519 for steel floor substructure components for gymnasiums), dimensions that satisfy that standard are adopted. Even when the spacing between adjacent steel joists 10 is determined from the perspective of satisfying the standard, it is preferable to ensure that the temperature-controlled air SA can come into contact with the floor material F evenly.

[0028] The tensile steel 30 is a member that supports the joist steel 10 and is made of a square steel pipe. Therefore, the tensile steel 30 also has openings at both longitudinal ends, and the space between these end faces is surrounded by steel material, allowing it to function as a culvert. The tensile steel 30 is typically made of the same square steel pipe (e.g., JIS G3466) as the joist steel 10, but square steel pipes of different sizes may also be used. The tensile steel 30 does not have an opening corresponding to the outlet 15 formed in the joist steel 10. The tensile steel 30 is arranged crosswise to the joist steel 10 and corresponds to a second square steel pipe. In this embodiment, the tensile steel 30 is arranged perpendicular to the joist steel 10. Furthermore, in this embodiment, a plurality of tensile steels 30 are arranged in parallel at a predetermined interval. The number of tensile steels 30 may be determined according to the size of the heating and cooling space R. The spacing between adjacent joists 30 is such that it can support the loads on the multiple joists 10 and floor material F, and if there is a specific standard for a particular purpose (for example, JISA6519 for steel floor substructure components for gymnasiums), dimensions that satisfy that standard are adopted. The joists 30 are supported by the support legs 21 and are therefore positioned above the slab of the building. This ensures that the space behind the heating and cooling space R (hereinafter referred to as "back space B") extends below the joists 30, ensuring a relatively large space.

[0029] As shown in FIG. 3(A), the support leg 21 includes a support plate 22, a fixing bolt 23, a support bolt 24, and a base plate 25. The support plate 22 is a member on which the tensile steel 30 is placed and is typically a long, thin metal plate. The support plate 22 is arranged to extend in a direction perpendicular to the longitudinal direction of the tensile steel 30 and protrudes on both sides beyond the width of the tensile steel 30. The support plate 22 has holes formed on both sides outside the width of the tensile steel 30, through which bolts can be inserted. The fixing bolt 23 is a member that fixes the tensile steel 30 to the support plate 22. The fixing bolt 23 is bent so as to surround three of the four side surfaces of the tensile steel 30 other than the side surface that is in contact with the support plate 22, and both ends are inserted into two holes in the support plate 22. The fixing bolt 23 is threaded at least in the portion that is inserted into the two holes in the support plate 22, and can be fixed to the support plate 22 by screwing in a nut. The support bolt 24 is a member that connects the support plate 22 and the base plate 25. The support bolt 24 is typically a fully threaded bolt cut to an appropriate length, with one end connected to the centroid of the support plate 22 and the other end connected to the centroid of the base plate 25. The base plate 25 is a member that fixes the support leg 21 to the slab. The base plate 25 is typically a rectangular metal plate-shaped member. The base plate 25 has holes formed therein for inserting anchors, so that it can be fixed to the slab using anchors.

[0030] As shown in the partial perspective view of the base member set 1 in FIG. 3(A) and the partial exploded perspective view of the base member set 1 in FIG. 3(B), a communication hole 28 is formed at the portion where the joist steel bars 10 and the tensile steel bars 30 intersect and contact each other. The communication hole 28 is formed by combining a joist communication hole 18 (see FIG. 3(B)) formed in the joist steel bars 10 with a tensile steel communication hole 38 (see FIG. 3(B)) formed in the tensile steel bars 30. The communication hole 28 is a hole that communicates the internal space of the joist steel bars 10 with the internal space of the tensile steel bars 30. The joist communication hole 18 and the tensile steel communication hole 38 are typically formed to the same size, but one may be formed to a size that encompasses the other. The communication holes 28 are typically formed at all locations of the intersections between the multiple joist steel bars 10 and the tensile steel bars 30 (thus forming a number equal to the number of joist steel bars 10 multiplied by the number of tensile steel bars 30), but may be formed only at some of the intersections. The portions where the communication holes 28 are formed (or the portions where the communication holes 28 are not formed) may be, for example, every other or every third intersection portion. At least one communication hole 28 is formed for each of the plurality of joist steel pieces 10 and tensile steel pieces 30. Therefore, the entire internal spaces of the plurality of joist steel pieces 10 and tensile steel pieces 30 are connected.

[0031] Looking at the partial perspective view of the base member set 1 from below shown in FIG. 4 , in this embodiment, inlet ports 16 are formed on the opposite surface 13 of the joist steel 10. The inlet ports 16 are openings that allow temperature-controlled air SA to flow into the internal space connecting each joist steel 10 and the tensile steel 30. The number and arrangement of the inlet ports 16 should be determined from the perspective of minimizing the difference in flow velocity of the temperature-controlled air SA flowing out from each of the multiple outlet ports 15 formed in the joist steel 10 and from the perspective of simplifying the distribution of the temperature-controlled air SA to each inlet port 16 as much as possible. In this embodiment, two inlet ports 16 are formed in each joist steel 10 between the two central tensile steels 30 of the multiple tensile steels 30 arranged at intervals in the longitudinal direction of the joist steel 10. The number and arrangement of the inlets 16 shown here are merely examples, and depending on the size of the cooling and heating space R, it may be preferable to form them at both ends of the joist steel 10 instead of or in addition to the longitudinal center. Alternatively, since the internal spaces of the joist steel 10 and the joist steel 30 are connected, the inlets 16 may be formed in the joist steel 30 instead of or together with the joist steel 10. In this embodiment, the back space B including the portion where the inlets 16 are formed is partitioned by an outlet partition plate 63 and an inlet partition plate 65 to form an underfloor chamber through which the temperature-controlled air SA flowing into the inlets 16 flows. The outlet partition plate 63 and the inlet partition plate 65 are supported by a partition support member 50.

[0032] FIG. 5 shows the configuration of the partition support member 50. The partition support member 50 is a member for supporting the outflow partition plate 63 and the inflow partition plate 65, and is typically attached to the joist steel 10. In this embodiment, the partition support member 50 is a resin molded product (typically a synthetic resin molded product), but it may be formed from materials other than resin, such as by processing and shaping a metal steel plate. The partition support member 50 is typically molded as a single unit, but for convenience, it will be described separately as a concave piece 51, an outflow support piece 53, and an inflow support piece 55. The concave piece 51 is the part that contacts the joist steel 10. The concave piece 51 has an appearance similar to a light channel steel. Due to this shape, the concave piece 51 is attached to the joist steel 10 by wrapping around the opposite surface 13 (see FIG. 2) and some of both adjacent surfaces 12 (see FIG. 2) of the joist steel 10. The concave piece 51 has a shape similar to that of a light channel steel, with the central portion in contact with the opposite surface 13, and side portions extending at right angles from both ends of this central portion in contact with the adjacent surface 12. These side portions do not reach the height of the outlet 15 that appears on the adjacent surface 12, and are typically formed at a height of about 1 / 3 to 1 / 2 of the height of the adjacent surface 12. Furthermore, these side portions are formed with a plurality of mounting holes 52 through which tapping screws for fixing to the joist steel 10 can be passed.

[0033] The outflow support pieces 53 are plate-shaped portions connected to the side portions of the recessed piece 51. The outflow support pieces 53 are connected to each of the pair of side portions of the recessed piece 51. The side portions of the recessed piece 51 to which each outflow support piece 53 is connected are the sides opposite the sides to which the central portion of the recessed piece 51 is connected. The outflow support pieces 53 are arranged parallel to an imaginary plane including the surface on which the central portion of the recessed piece 51 exists. The outflow support pieces 53 extend outward from the light-gauge steel-like shape of the recessed piece 51. Therefore, when the partition support member 50 is attached to the joist steel 10, the outflow support pieces 53 extend in a direction away from the adjacent surface 12. Because the outflow support pieces 53 support the outflow partition plate 63, they are formed to a size that can adequately support the outflow partition plate 63.

[0034] The inflow support piece 55 is a plate-shaped member extending at an angle relative to the central portion of the recessed piece 51 and the outflow support piece 53. In this embodiment, the inflow support piece 55 extends perpendicular to the central portion of the recessed piece 51 and the outflow support piece 53. The inflow support piece 55 is connected to the recessed piece 51 and the outflow support piece 53 at one end in the direction in which the connecting edge between the recessed piece 51 and the outflow support piece 53 extends. The inflow support piece 55 has a notch so that the end connected to the recessed piece 51 and the outflow support piece 53 (the upper end edge in the example shown in Figure 5) is flush with the surfaces of the recessed piece 51 and the outflow support piece 53. The inflow support piece 55 extends in a direction away from the opposite surface 13 when the partition support member 50 is attached to the joist steel 10. Since the inflow support piece 55 supports the inflow partition plate 65, it is formed to a size that can adequately support the inflow partition plate 65.

[0035] When installing the base member set 1 on a building, first, the support legs 21 are anchored onto the building slab. The layout of the support legs 21 is determined based on the tensile steel beams 30 to be laid. The base member set 1 is constructed by laying multiple tensile steel beams 30 in parallel at a predetermined interval, and then laying multiple joist steel beams 10 in parallel at a predetermined interval on the tensile steel beams 30. The predetermined spacing between the multiple joist steel beams 30 is determined to satisfy a predetermined standard (e.g., JISA 6519 for steel floor substructure components for gymnasiums). Furthermore, to ensure that the temperature-controlled air SA is evenly in contact with the floor material F, a spacing that allows the required flow rate of the temperature-controlled air SA to be supplied to the joist steel beams 10 is determined. It is preferable to satisfy both requirements. The support legs 21 are fixed onto the slab at positions corresponding to the spacing between the joist steel beams 30 determined based on the above considerations.

[0036] Once the support legs 21 are fixed onto the slab, the tensile steel beams 30 are adjusted to their lengths according to the floor area of ​​the heating and cooling space R, and then placed on the support plate 22 so that their longitudinal direction is horizontal. At this time, the tensile steel beams 30 are placed on the support plate 22 so that the tensile steel beam connection holes 38 face upward (toward the joist steel beams 10 to be laid later) (so that they appear on the top surface of the tensile steel beams 30). The tensile steel beams 30 are also placed on the support plate 22 so that the tensile steel beam connection holes 38 of other tensile steel beams 30 are aligned on an imaginary horizontal line that passes through one tensile steel beam connection hole 38 and is perpendicular to the tensile steel beams 30. Once the tensile steel beams 30 are placed on the support plate 22, fixing bolts 23 are attached to secure the tensile steel beams 30 to the support legs 21. Then, end caps 29 are attached to the openings on both end faces of each tensile steel beam 30. The end caps 29 may be attached to each tensile steel 30 before the tensile steel 30 is placed on the support plate 22 or before the fixing bolts 23 are attached. When the end caps 29 are attached, only the tensile steel connecting holes 38 are left open in each tensile steel 30.

[0037] Next, the joist steel bars 10 are placed on the joist steel bars 30. At this time, with the opposite surface 13 facing downward (toward the joist steel bars 30), each joist steel bar 10 is laid on the joist steel bars 30 so that the joist connection holes 18 align with the joist connection holes 38. In this embodiment, each joist steel bar 10 is arranged so that it is perpendicular to each joist steel bar 30. Furthermore, by aligning the joist connection holes 18 and the joist connection holes 38, connection holes 28 are formed, connecting the interiors of the joist steel bars 10 and the joist steel bars 30. Furthermore, in this embodiment, the multiple joist steel bars 10 are arranged so that the imaginary line connecting the inlets 16 formed on the opposite surface 13 of each joist steel bar 10 is aligned parallel to the joist steel bars 30. After the joist steel bars 10 are laid, the adjacent surfaces of the joist steel bars 10 and the joist steel bars 30 are fixed with fixing brackets 19 (see FIG. 3), such as L-shaped brackets. Thereafter, end caps 29 (see FIG. 1) are attached to the openings on both end faces of each joist steel 10. Note that the attachment of the end caps 29 to each joist steel 10 may be performed before placing the joist steel 10 on the tensile steel 30 or before attaching the fixing brackets 19.

[0038] Once the placement of the joist steel beams 10 is complete, the partition support member 50 is attached to the joist steel beams 10. The partition support members 50 are attached in pairs, sandwiching the inlet 16 between them. The pairs of partition support members 50 are typically attached so that their inlet support pieces 55 face each other. Furthermore, the partition support members 50 attached to adjacent joist steel beams 10 are attached so that their inlet support pieces 55 are aligned (positioned on the same imaginary vertical plane). Once the partition support member 50 is fitted into the joist steel beams 10 in this position, tapping screws are passed through the mounting holes 52 and driven into the joist steel beams 10. This secures the partition support member 50 to the joist steel beams 10. Once the partition support member 50 is attached to the joist steel beams 10, the inlet partition plate 65 is attached to the inlet support piece 55. Furthermore, the inlet partition plate 65 is placed on the outlet support piece 53. At this time, if a gap occurs between the upper end of the inflow partition plate 65 and the lower surface of the outflow partition plate 63, it is advisable to close the gap with a sponge-like rubber material or caulking material.

[0039] As shown in FIGS. 1 and 4 , the inlet partition plate 65 is a plate-like member arranged in an upright position (with the normal to its surface horizontal) in the rear space B and divides the rear space B horizontally. In this embodiment, the inlet partition plate 65 extends parallel to the steel joists 30. The inlet partition plate 65 is aligned along each of the inlet ports 16 arranged parallel to the steel joists 30 and typically has a length equivalent to the distance from one end to the other in the longitudinal direction of the steel joists 30. The inlet partition plate 65 may be formed to this length by connecting multiple plates. The inlet partition plate 65 has a height from the slab to which the support legs 21 are fixed to the opposite surface 13 of the steel joists 10. Two inlet partition plates 65 are arranged at an interval in the longitudinal direction of the steel joists 10 and form both side walls of the flow path for the temperature-controlled air SA. The inlet port 16 is included in the flow path for the temperature-controlled air SA between the two inlet partition plates 65. In other words, two inlet partition plates 65 are provided so as to be able to entirely enclose the space vertically below each of the inlets 16 arranged along the longitudinal direction of the steel tensile members 30. The inlet partition plates 65 are fixed to the inlet support pieces 55 with screws and / or adhesive.

[0040] The outflow partition plate 63 is a plate-like member that is arranged in the rear space B with its surface extending horizontally (with the normal line of the surface vertical), and that divides the rear space B in the vertical direction. The outflow partition plate 63 is arranged between adjacent joist steel members 10. The outflow partition plate 63 has a width that fits exactly between adjacent joist steel members 10. The length of the outflow partition plate 63 (the length in the direction parallel to the longitudinal direction of the joist steel members 10) is formed to a length that covers the top of the opposing inflow partition plates 65. The outflow partition plate 63 is arranged in each gap between multiple adjacent joist steel members so that it can cover the entire top of the opposing inflow partition plates 65. When the outflow partition plate 63 is placed on the outflow support piece 53, it is positioned below the lower end of the outflow port 15 formed in the joist steel members 10. The back space B surrounded by the outflow partition plate 63, the pair of inflow partition plates 65, and the slab is a space where the temperature-controlled air SA exists before entering the inside of the joists 30 and the floor joists 10, and will be referred to as the "inflow space BP" (see FIG. 2). The inflow space BP faces (is exposed to) the inlet 16, but does not face (is not exposed to) the outlet 15. The back space B above the outflow partition plate 63 is a space where the temperature-controlled air SA that has flowed out from the outlet 15 exists, and will be referred to as the "outflow space BS." The outlet space BS faces (is exposed to) the outlet 15, but does not face (is not exposed to) the inflow inlet 16. The outflow space BS is connected to the back space B outside the inflow space BP (the back space B where the outflow partition plate 63 is not arranged but faces the outlet 15).

[0041] Next, the configuration of the heating and cooling system 100 other than the base member set 1 will be described. The temperature control device 91 (see FIG. 1) is a device that generates temperature-controlled air SA adjusted to a temperature that can perform radiant heating and cooling of the heated and cooled space R. A packaged air conditioner is typically used as the temperature control device 91, but an air handling unit or the like may also be used. The temperature control device 91 is typically installed in a position where it can supply the blown-out temperature-controlled air SA to the inflow space BP. The temperature control device 91 may be installed outside the area where the heated and cooled space R is formed, in a room adjacent to the heated and cooled space R, or in a room away from the heated and cooled space R, and may be configured to use a duct to guide the temperature-controlled air SA to the inflow space BP.

[0042] After the base member set 1 and the temperature control equipment 91 are installed and the heating and cooling system 100 is constructed, flooring material F is laid on top of the joist steel 10 (see FIG. 2). This forms the floor surface of the heating and cooling space R, dividing the floor. The back surface of the flooring material F (the rear space B side) is in contact with the outlet 15 formed in the joist steel 10. The flooring material F is also formed with communication openings (not shown) that allow the temperature-controlled air SA that flows out of the outlet 15 of the joist steel 10 into the rear space B to flow into the heating and cooling space R. By introducing the temperature-controlled air SA into the heating and cooling space R through the communication openings, it is possible to enjoy the heating and cooling effect due to convection. Depending on the size of the heating and cooling space R, it is preferable to form two to four communication openings in the corners of the heating and cooling space R. The communication openings may be provided with a grid (not shown) on the floor surface of the heating and cooling space R to prevent objects from falling. Furthermore, it is preferable that an outlet (not shown) is formed on the wall or ceiling surface of the heating and cooling space R to discharge the temperature-controlled air SA that has flowed into the heating and cooling space R to the outside of the heating and cooling space R. A return air duct (not shown) that guides the air in the heating and cooling space R to the temperature adjustment device 91 may be connected to the outlet (not shown).

[0043] Next, the operation (operating conditions) of the heating and cooling system 100 will be described. The operation of the base member set 1 will be described as part of the operation of the heating and cooling system 100. The temperature control device 91 generates temperature-controlled air SA adjusted to a temperature suitable for radiant heating and cooling of the heating and cooling space R (depending on the set temperature, for example, 18 to 23°C when cooling, and 30 to 35°C when heating). Radiant heating and cooling is generally designed to reduce the difference between the temperature of the temperature-controlled air and the outside air temperature compared to heating and cooling using only convection (heating and cooling performed by supplying temperature-controlled air into the heating and cooling space), so less energy is required to generate the temperature-controlled air SA. The temperature-controlled air SA generated by the temperature control device 91 is supplied to the inflow space BP directly or via a duct (not shown).

[0044] As the temperature-controlled air SA supplied to the inflow space BP increases, it fills the inflow space BP. Eventually, the temperature-controlled air SA flows through the inflow ports 16 in the inflow space BP into the internal space of each joist steel member 10. The temperature-controlled air SA that flows into the interior of the joist steel member 10 diffuses throughout the entire internal space of the joist steel member 10 and also throughout the internal space of the joist steel member 30, which is connected to the joist steel member 10 via the communication holes 28. As the temperature-controlled air SA enters the interior of the joist steel member 10 through the inflow ports 16 and diffuses throughout the internal space of the joist steel member 10 and the joist steel member 30, some of it flows out into the outflow space BS through the multiple outlets 15 formed in each joist steel member 10. As the temperature-controlled air SA spreads throughout the entire interconnected internal space of each joist steel member 10 and each joist steel member 30, the pressure difference between locations decreases. In this case, the joist steel member 30 can be considered to function as a pressure equalizing pipe. When the pressure difference between various locations in the internal space of each joist steel 10 and each tensile steel 30 becomes smaller, the difference in flow speed of the temperature-controlled air SA flowing out from each of the outlets 15 formed in each joist steel 10 also becomes smaller. As a result, the difference in the travel distance of the temperature-controlled air SA flowing out from each outlet 15 becomes smaller, and the temperature-controlled air SA can be supplied to each location approximately equally.

[0045] The temperature-controlled air SA flowing out of each outlet 15 diffuses along the back surface of the flooring material F and flows toward the adjacent steel joists 10. As the temperature-controlled air SA flows along the back surface of the flooring material F, it contacts the flooring material F and transfers cold (when cooling) or heat (when heating) to the flooring material F. This cools or heats the flooring material F. If the size of the outlet 15 appearing on the adjacent surface 12 is large enough to allow the temperature-controlled air SA flowing out of the outlet 15 to form a jet, the boundary film formed between the temperature-controlled air SA and the flooring material F can be broken as the temperature-controlled air SA flows. A boundary film is an extremely thin region that exists at the phase boundary when fluids are moving relative to each other and maintains a laminar flow state. Generally, if a boundary film where air stagnates between the flooring material F and the flow of the temperature-controlled air SA exists, the surface heat transfer resistance increases, preventing the cold or heat contained in the temperature-controlled air SA from being efficiently transferred to the flooring material F. However, breaking the boundary film can improve the heat transfer coefficient. The flooring material F also receives cold or heat from the steel joists 10 that it is in contact with, and is cooled or heated accordingly. Because the steel joists 10 and the steel joists 30 are made of steel plates, they have relatively high thermal conductivity and can efficiently transfer cold or heat to the flooring material F. Then, the cold or heat is radiated from the cooled or heated flooring material F to the air-conditioned space R, thereby cooling or heating the air-conditioned space R.

[0046] The temperature-controlled air SA that has transferred cold or hot heat to the floor material F rises in temperature during cooling and falls in temperature during heating. The temperature-controlled air SA that has exchanged heat with the floor material F and is present in the back space B (or outflow space BS) flows into the cooling and heating space R through a communication port (not shown) and convects within the cooling and heating space R. The temperature-controlled air SA that flows into the cooling and heating space R is either at a temperature equivalent to that of the floor material F or lower than that of the floor material F during cooling and higher than that of the floor material F during heating, and therefore contributes to the heating and cooling of the cooling and heating space R. The temperature-controlled air SA that flows into the cooling and heating space R is then returned to the temperature control device 91, for example, via a return air duct (not shown), where it is supplied again to the inflow space BP after its temperature is adjusted. Alternatively, the temperature-controlled air SA in the cooling and heating space R is released into the outside air, and the air released into the outside air is newly temperature-adjusted by the temperature control device 91 and supplied to the inflow space BP. After the temperature-controlled air SA is supplied to the inflow space BP, the above-mentioned actions are repeated.

[0047] As described above, the base member set 1 according to this embodiment uses square steel pipes as the joist steel 10 and the joist steel 30. This eliminates the need to subsequently block the opening side to form a flow path for the temperature-controlled air SA inside, simplifying the configuration for distributing the temperature-controlled air SA. Furthermore, the inlet partition plate 65 and the outlet partition plate 63 are easily supported, simplifying the formation of the inlet space BP. Furthermore, the heating and cooling system 100 according to this embodiment transfers cold or hot heat from the temperature-controlled air SA and the joist steel 10 to the flooring material F, changing the temperature of the flooring material F, and then radiates the cold or hot heat from the flooring material F, thereby cooling or heating the cooling space R.

[0048] In the above description, the temperature-controlled air SA flowing out from the joist steel 10 flows directly out from the outlet 15, but the outlet 15 may be provided with a jet unit as described below. FIG. 6(A) is a perspective view of the jet unit 80A. FIG. 6(B) is a perspective view of the jet unit 80A attached to the joist steel 10. The jet unit 80A has a flat plate 81, a side plate 83, and a conversion plate 84, which are typically integrally formed by resin molding. The flat plate 81 is formed in a rectangular shape. The long sides of the flat plate 81 are longer than the width of the joist steel 10 (the length in the direction perpendicular to the longitudinal direction of the joist steel 10). The long sides of the flat plate 81 may be approximately 1.5 to 2.5 times the width of the joist steel 10, and in this embodiment, are approximately twice the width. The short sides of the flat plate 81 are formed to a length equal to the width of the outlet 15 (the length of the outlet 15 in the longitudinal direction of the joist steel 10), and preferably are formed to a size such that the jet unit 80A fits exactly into the recess of the outlet 15. An opening 82 is formed in the flat plate 81. In this embodiment, two openings 82 of the same shape and size are formed side by side in the short side direction of the flat plate 81. In other words, the openings 82 are two rectangular holes that connect the flat plate 81. The openings 82 are formed to a size that allows all of the multiple formed holes to be encompassed by the outlet 15 in the opposing surface 11. The openings 82 are formed at the center positions of the flat plate 81 in both the long side direction and the short side direction (i.e., at the centroid position of the flat plate 81).

[0049] The side plates 83 are formed in the shape of a long, narrow rectangle. The side plates 83 are connected to each of a pair of long sides of the flat plate 81. The long sides of the side plates 83 have the same length as the long sides of the flat plate 81, and the short sides have a length corresponding to the depth of the outlet 15 (the distance from the opposing surface 11 toward the opposite surface 13 on the adjacent surface 12). The pair of side plates 83 extend on the same side of the flat plate 81, perpendicular to the surface of the flat plate 81. The conversion plate 84 is formed in the shape of a rectangular plate. The conversion plate 84 is connected to a connecting portion of the flat plate 81 between the two holes of the opening 82. The conversion plate 84 extends perpendicular to the surface of the flat plate 81, in a direction opposite to the extension direction of the side plates 83 relative to the flat plate 81. The side of the conversion plate 84 connected to the flat plate 81 is formed to a length that is approximately the same as the width of the joist steel 10 and can be inserted from the outlet 15 into the joist steel 10. The conversion plate 84 is formed so that the side extending perpendicular to the surface of the flat plate 81 is approximately 1 / 4 to 1 / 2 the length of the height of the adjacent surface 12 (the distance between the opposing surface 11 and the opposite surface 13), and is typically formed to be approximately 1 / 3 the length of the height of the adjacent surface 12.

[0050] The jet unit 80A configured in this manner is attached to the joist steel 10 so that the conversion plate 84 is inserted into the interior of the joist steel 10 through the outlet 15 and the flat plate 81 abuts against the bottom of the outlet 15 on the adjacent surface 12. At this time, the side plates 83 do not protrude upward from the opposing surface 11, and the flat plate 81 and the pair of side plates 83 partially protrude outward from both adjacent surfaces 12. When the jet unit 80A is attached to the joist steel 10, a portion of the temperature-controlled air SA flowing through the internal space of the joist steel 10 is captured by the conversion plate 84 and guided to the opening 82, and then flows out through the outlet 15. The temperature-controlled air SA flowing out from the outlet 15 is guided by the flat plate 81 and the pair of side plates 83, which reduces diffusion and improves directionality compared to when the jet unit 80A is not attached. This allows the temperature-controlled air SA flowing out from the outlet 15 to reach a greater distance, increasing the area over which heat is transferred from the temperature-controlled air SA to the floor material F, thereby suppressing temperature variations in the floor material F. Although the jet unit 80A is typically a resin molded product, it may also be formed from a thin steel plate. When the jet unit 80A is formed from a thin steel plate, typically a single rectangular thin steel plate may be bent at the boundary between the flat plate 81 and the side plate 83 to form them into a single unit, and a conversion plate 84 may be joined to this.

[0051] FIG. 7(A) is a perspective view of a jet unit 80B according to a modified example, and FIG. 7(B) is a perspective view of the jet unit 80B attached to a steel joist 10. The jet unit 80B differs from the jet unit 80A (see FIG. 6(A)) in that it is provided with flow straightening folds 85. The flow straightening folds 85 are formed in the shape of an elongated rectangular plate and are provided on the flat plate 81 in a portion that protrudes outward from the adjacent surface 12 when the jet unit 80B is attached to the steel joist 10. The flow straightening folds 85 are typically formed at the same height as the side plates 83. One or more flow straightening folds 85 are arranged parallel to the side plates 83 so as to divide the flow path of the temperature-controlled air SA between the pair of side plates 83 into multiple sections. The remaining configuration of the jet unit 80B, including the materials, is the same as that of the jet unit 80A (see FIG. 6(A)). The jet unit 80B configured in this manner is provided with the flow straightening folds 85, so that the temperature-controlled air SA flowing out from the outlet 15 is straightened, and the directionality is further improved.

[0052] FIG. 8(A) is a perspective view of a jet unit 80C according to another modification, and FIG. 8(B) is a perspective view of the jet unit 80C attached to a steel joist 10. The jet unit 80C differs from the jet unit 80A (see FIG. 6(A)) in the following ways. First, the conversion plate 84 provided in the jet unit 80A (see FIG. 6(A)) is not provided. The opening 82 of the jet unit 80C is a single rectangular hole. In other words, the jet unit 80C does not have the flat plate 81 connecting the two rectangular holes present in the jet unit 80A (see FIG. 6(A)). Furthermore, when the jet unit 80C is attached to the steel joist 10, the distance between the pair of side plates 83 in the portion that protrudes outward beyond the adjacent surface 12 is tapered so that it becomes shorter as it moves away from the adjacent surface 12. In the jet unit 80C, the width of the flat plate 81 is shortened to match the shortened spacing between the pair of side plates 83. Furthermore, a confluence fold 87 is provided on the flat plate 81 in a portion that protrudes outward beyond the adjacent surface 12 when the jet unit 80C is attached to the joist steel 10. The confluence fold 87 is provided at a midpoint in the width between the side plates 83 so as to bisect the flow path of the temperature-controlled air SA between the pair of side plates 83. The confluence fold 87 originates at the position of the opening 82, extends in a direction away from the opening 82, and protrudes several millimeters to several tens of millimeters from the end (tip) of the flat plate 81. The remaining configuration of the jet unit 80C, including the materials, is the same as that of the jet unit 80A (see FIG. 6(A)). The jet unit 80C configured in this manner increases the flow velocity of the outflowing temperature-controlled air SA, further extending the reach of the outflowing temperature-controlled air SA.

[0053] In the above explanation, the inlet 16 is formed on the opposite surface 13 of the joist steel 10, but it may also be formed on the adjacent surface 12 of the joist steel 10. As mentioned above, the inlet 16 may be formed on the joist steel 10 and, alternatively, on the tensile steel 30. Even when the inlet 16 is formed in this manner, the internal space of the joist steel 10 and the tensile steel 30 is filled with temperature-controlled air SA, and the temperature-controlled air SA can be appropriately ejected from the outlet 15 due to static pressure.

[0054] In the above explanation, the opposing surface 11 of the joist steel 10 is in contact with the back surface of the floor material F, but it may also be positioned away from the floor material F (close to the floor material F) to the extent that the temperature-controlled air SA flowing out from the outlet 15 can diffuse along the back surface of the floor material F.

[0055] In the above description, the base material set 1 is described as supporting floor material F, but the base material set 1 may be used to support ceiling material and / or wall material in addition to or instead of supporting floor material F. If the base material set 1 is used to support ceiling material, etc., the first square steel pipe (joist steel 10) and the second square steel pipe (head joist steel 30) shown in FIG. 1 are turned upside down, and the second square steel pipe and / or the first square steel pipe are supported from the ceiling frame with suspension bolts or the like. If the base material set 1 is used to support wall material, the first square steel pipe (joist steel 10) and the second square steel pipe (head joist steel 30) shown in FIG. 1 are placed upright.
