Hereinafter, the present invention will be described in detail based on the embodiments. The present invention is not limited to the following embodiments.

FIG. 1 is a schematic view of the interior of a building according to an embodiment. As shown in the figure, a large number of radiant panels 1 which are ceiling materials are arranged vertically and horizontally on one surface of the ceiling of the room R1.

As shown in FIG. 2, the radiation panel 1 has a rectangular (rectangular) outer shape, and is composed of a panel base material 2 which is four plates arranged in parallel and a pipe 3 mounted on the upper surface thereof. ing. Each of the panel base materials 2 has an outer shape extending elongated in the length direction, and is arranged in parallel so that the long sides are adjacent to each other. Has been done.

As shown in FIG. 3, the panel base material 2 is a member obtained by molding aluminum into a corrugated plate shape by extrusion molding, and one panel base material 2 has a semicircular downward ridge 4 Are formed in four rows side by side.

In each panel base material 2, one side edge of both side edges along the length direction is formed into a shape having a step-up portion 2a, and the other side edge is formed into a shape having a step-down portion 2b, and is adjacent to each other. By superimposing the combined step-up portion 2a and step-down portion 2b, the radiation panels 1 are connected so as to exhibit the appearance of a single plate as a whole. The stepped-up portion 2a is formed so as to extend to a position where it abuts on the engaging rib 9 (described later) of the adjacent panel base material 2.

On the other hand, as shown in FIG. 2, the pipe 3 is bent so as to meander in a zigzag manner in a plan view, and the straight portion of the pipe 3 is the central portion of each panel base material 2 (second row from one side edge; FIG. In 3, it is fitted in the downward ridge 4 (second row from the left edge). The downward ridge 4 at the center of each panel base material 2 is formed with an upward rib 5 for holding the pipe 3. The upward rib 5 is formed so as to extend the peripheral wall of the downward ridge 4 slightly upward, extends to a position slightly above the left and right ends of the pipe 3, and is more than the lower half of the outer peripheral surface of the pipe 3 (more than the lower half on the outer peripheral surface of the pipe 3). It is formed so as to form a circular cross-sectional portion together with the downward ridge 4 so as to hold the portion (the portion from the lower half portion to slightly above). The pipe 3 is fitted and held in the downward ridge 4 from above by elastically deforming and pushing the upward rib 5 so as to expand outward (forced fitting).

The portion of the pipe 3 that is bent in a U-shape in a plan view protrudes upward from the downward ridge 4 so as to be raised slightly diagonally upward from the extension line of the straight portion. Further, as shown in FIG. 2, the one end portion 3a and the other end portion 3b of the pipe 3 are bent so as to extend in parallel with one short side portion of the panel base material 2, and the one end portion 3a and the other end portion are bent. It faces in the opposite direction to 3b. Then, one end 3a of the pipe 3 in one of the adjacent radiating panels 1 and the other end 3b of the pipe 3 in the other radiating panel 1 are connected by a joint pipe 6 shown by a dotted line in FIG.

As the pipe 3, a pipe material called a "three-layer pipe" is used. This three-layer tube has a three-layer structure in which a metal layer is sandwiched between resin layers from inside and outside, and is excellent in corrosion resistance and dew condensation prevention effect.

As shown in FIGS. 2 and 3, suspension frames 7, which are frame materials (crosspieces), are arranged on the pipe 3 so as to overlap each other from above. The suspension frame 7 has a U-shaped cross section (grooved steel) that opens downward, and a plurality of notched engagement grooves 8 are formed on the side plates thereof. Each of the notch engaging grooves 8 has a narrow portion extending upward from the lower end edge of the side plate of the suspension frame 7, and an enlarged portion extending in a horizontally long rectangular shape at the upper end of the narrow portion, and has a substantially T-shape as a whole. It is formed to form a rectangle. The narrow portion has a shape that expands to both sides from the middle portion to the lower end portion. On the other hand, an engaging rib 9 that fits into the notch engaging groove 8 is integrally formed on both side edges of the panel base material 2 along the length direction, and a panel base is formed on the tip edge of the engaging rib 9. A claw that projects in a trapezoidal cross section is formed inside the material 2, and the claw is elastically engaged with a step portion formed from the narrow portion to the enlarged portion of the notch engagement groove 8 to suspend the material 2. The pipe 3 is held by the frame 7 so as to be pressed against the panel base material 2, and the four panel base materials 2 are connected in a single plate shape, whereby the radial panel 1 is formed.

The portion of the side plate of the suspension frame 7 that corresponds to the pipe 3 is cut out in a trapezoidal shape that expands downward to form a pipe receiving recess 11. Three suspension frames 7 are arranged at a portion near both ends and an intermediate portion in the length direction of the radiation panel 1, and nuts 10 are placed on the lower surface of the portion near both ends of the top plate of the suspension frame 7 located at the intermediate portion. It is fixed by welding. The number of suspension frames 7 to be arranged can be arbitrarily set.

On the other hand, although not shown, an intermediate support frame configured to spread in a frame shape along the ceiling surface is suspended by a first suspension bolt on the ceiling slab, and a second suspension bolt 14 is suspended on the intermediate support frame. The suspension frame 7 is suspended from the ceiling by screwing the second suspension bolt 14 into the nut 10 and fixing it from above with another nut 15 as shown in FIG. It is fixed.

As described above, a large number of radiating panels 1 are arranged side by side on the ceiling of the room R1, and the pipes 3 are connected to each other by the joint pipes 6 between the radiating panels 1, whereby most of the ceiling is covered. A heat medium flow path is formed so as to distribute the heat medium, but it may be difficult to arrange the pipe 3 depending on the portion of the ceiling. For example, in a portion where an inspection port is provided, the pipe 3 cannot be arranged because this portion can be opened and closed. In the present embodiment, a panel having a part different from that of the radiation panel 1 is used at the site where the inspection port is provided.

FIG. 4 is a plan view of the inspection port panel 16, and FIG. 5 is a cross-sectional view taken along the line IV-IV of FIG. As shown in FIGS. 4 and 5, most of the structure of the inspection port panel 16 other than the tapered portion 18 described later is basically the same as that of the radiation panel 1. Therefore, the same parts or members as those of the radiation panel 1 are designated by the same reference numerals, and the description thereof is basically omitted unless necessary.

In the inspection port panel 16, the most different main difference from the above-mentioned radiation panel 1 is that the pipe 3 is not arranged, and in the suspension frame 17, the pipe receiving recess 11 is formed in the suspension frame 7 in the radiation panel 1. It is a point where the tapered portion 18 is formed at the portion.

At the lower end of the side plate of the suspension frame 17, wedge-shaped (substantially inverted V-shaped) notches 19 and 19 are formed at positions corresponding to the pair of upward ribs 5 and 5 in the panel base material 2, respectively. A tapered portion 18 is formed between the notches 19 and 19 on both sides so as to form a trapezoidal shape that tapers downward.

The distance between the upper right end and the upper left end of the tapered portion 18, that is, the distance between the upper ends of the notches 19 and 19 on both sides is larger than the distance between the upper ends of the upward ribs 5 and 5 in the panel base material 2, while the taper portion 18 is tapered. The distance between the lower right end and the lower left end of the portion 18 is smaller than the distance between the upper ends of the upward ribs 5 and 5. Further, the tip edge (lower edge) of the tapered portion 18 is formed so as to be on the same straight line as the edge (lower edge) of the suspension frame 17.

As in the case of the suspension frame 7 of the radiation panel 1, the suspension frame 17 of the inspection port panel 16 uses the engagement structure of the engagement ribs 9 to form the four panel base materials 2 into a single plate shape. They are arranged so as to be connected to each other, whereby the inspection port panel 16 is configured.

At that time, more specifically, the tips of the engaging ribs 9 on both sides of the panel base material 2 are inserted into the notch engaging groove 8 from below, and the claws of the engaging rib 9 are inserted into the stepped portion of the notch engaging groove 8. The panel base material 2 is attached to the suspension frame 17 by elastically engaging with.

At this time, the panel base material 2 is attached to the suspension frame 17 by abutting against the suspension frame 17, and the upward ribs 5 and 5 project from the panel base material 2 in the abutting direction (upward), while the panel base material 2 is attached to the suspension frame 17. Is an inclined portion 20R, 20L in which both side edges of the tapered portion 18 are inclined with respect to the abutting direction. Then, when the panel base material 2 is abutted against the suspension frame 17, the tips of the upward ribs 5 and 5 abut on both side edges of the tapered portion 18 on the way. As a result, the movement of the panel base material 2 in the abutting direction (upward) is restricted, and the movement of the suspension frame 17 along the length direction (left-right direction in FIG. 5) is also restricted. That is, the panel base material 2 is positioned with respect to the suspension frame 17.

On the other hand, as described above, the panel base material 2 is restricted from moving downward by the engaging structure of the engaging rib 9. Therefore, with the above mounting structure, the panel base material 2 and the suspension frame 17 can be accurately positioned so as not to shift in the butt direction (vertical direction) and the length direction (horizontal direction) of the suspension frame 17 without rattling. It is designed to be securely attached.

Furthermore, in the inspection port panel 16, the engaging rib 9 elastically engages with the notch engaging groove 8 only by abutting the panel base material 2 against the suspension frame 17 and pressing the panel base material 2 against the suspension frame 17. It is fixed, and as described above, the upward ribs 5 and 5 are positioned by abutting on the inclined portions 20R and 20L of the tapered portion 18, so that the panel base material 2 can be attached to the suspension frame 17 by a single operation. It can be easily positioned and installed.

Here, in the above-mentioned mounting structure, according to the engagement structure by the engagement rib 9, the downward movement of the panel base material 2 is restricted as described above, but in the enlarged portion of the notch engagement groove 8. Since it is necessary to secure the play P1 above the inserted engaging rib 9 (see FIGS. 3 and 5), the upward movement of the panel base material 2 is not restricted in this portion, and therefore. A deviation may occur in the vertical direction at the portion of this play P1. In the case of the radial panel 1, as shown in FIG. 3, the upper end of the pipe 3 is brought into contact with the inner inner edge (upper end edge) of the pipe receiving recess 11 in the suspension frame 7 so that the upper end of the pipe 3 is brought into contact with the upper side of the panel base material 2. I try to regulate movement.

However, when the pipe 3 cannot be arranged like the inspection port, there is a lack of means for restricting the upward movement of the panel base material 2. For this reason, conventionally, as shown in FIG. 6, at the inspection port or the like, the pipe is cut so as to have a length slightly longer than the width of the suspension frame 7 to obtain a short filler pipe 21, and the filler pipe 21 is used. , The upper end of the filler pipe 21 is brought into contact with the inner inner edge of the pipe receiving recess 11 in the suspension frame 7 by fitting it into the downward ridge 4 of the panel base material 2 instead of the pipe 3. I was trying to regulate the movement to. According to such a mounting structure, it takes time and effort to cut and fit the pipe, which is a factor that increases the cost.

On the other hand, in the inspection port panel 16 according to the present embodiment, as described above, the upward ribs 5 and 5 are positioned by being brought into contact with the inclined portions 20R and 20L of the tapered portion 18, so that the pipe is positioned. The panel base material 2 can be easily attached to the suspension frame 17 without the trouble of cutting and fitting.

Further, in the mounting structure in which the movement of the panel base material 2 upward is restricted by the pipe 3 or the filler pipe 21, the engaging rib 9 is elastically deformed, so that it is along the left-right direction (the length direction of the suspension frame 7). The movement of the panel base material 2 is not strictly regulated, and therefore there is a possibility that the panel base material 2 may be displaced in the left-right direction. On the other hand, in the inspection port panel 16 according to the present embodiment, as described above, it faces upward. The contact between the ribs 5 and 5 and the inclined portions 20R and 20L regulates the movement in the left-right direction so that the ribs 5 and 5 are accurately positioned so as not to shift.

Furthermore, when the structures are brought into contact with each other so as to be accurately abutted at a predetermined position, it is necessary to form the structure with high accuracy. In the mouth panel 16, the upward ribs 5 and 5, which are protrusion structures, are brought into contact with the inclined portions 20R and 20L that are inclined with respect to the abutting direction, so that there is some error in the dimensions. In particular, the upward ribs 5 and 5 can be slightly elastically deformed, so that even if the protrusion length of the upward ribs 5 and 5 is slightly excessive, for example, the upward ribs 5 and 5 can be deformed to some extent. It can be elastically deformed and come into contact with the inclined portions 20R and 20L. Further, by bringing the upward ribs 5 and 5 into contact with the inclined portions 20R and 20L, the inclined portions 20R and 20L function as guides so that the upward ribs 5 and 5 are guided to a predetermined mounting position and positioned. Can function.

The inspection port panel 16 according to the present embodiment has the same dimensions and shape as the radiation panel 1, and the configuration of the panel base material 2 and the engagement structure by the engagement ribs 9 are the same as in the case of the radiation panel 1. For example, in the ceiling portion of the room R1 shown in FIG. 1, it is arranged so as to be replaced with one of a large number of radiating panels 1 arranged in an aligned manner, and is opened and closed by an opening / closing mechanism. Can be installed (not shown). Therefore, the inspection port panel 16 in the arranged state is almost indistinguishable from the surrounding radiation panel 1 as far as it is viewed from the room R1.

(Change mode)
In the present invention, in addition to the above embodiments, various modifications can be made, for example, as listed below. In the following modification embodiments, the same parts and members as in the above embodiment are designated by the same reference numerals, and the description thereof will be omitted unless necessary.

(1) In the above embodiment, in the inspection port panel 16, the upward ribs 5 and 5 of the panel base material 2 sandwich the tapered portion 18 of the suspension frame 17 in between, and the inclined portion 20R of the tapered portion 18 is sandwiched between them. , 20L was configured to be positioned, but as shown in FIG. 7, for example, the upward ribs 5 and 5 abut on the inclined portions 22R and 22L on the outer side from the inside. It may be configured to be positioned.

In the inspection port panel 23 according to the modified mode (1), positioning recesses 25 are formed at the lower end of the side plate of the suspension frame 24 by being cut out in a trapezoidal shape extending downward, and both sides of the positioning recess 25 are formed. The edges are inclined portions 22R and 22L. The positioning recess 25 is formed so as to have a vertical dimension (notch depth) H1 such that the upper ends of the upward ribs 5 and 5 are slightly deeper than the depth reached when the panel base material 2 is attached to the suspension frame 24. ing. Further, the distance between the upper right end and the upper left end of the positioning recess 25, that is, the length of the upper end edge (inner inner edge) is the distance between the upper right end and the upper left end of the upward ribs 5 and 5 (upper end of the upward ribs 5 and 5). The distance between the lower right and lower left of the positioning recess 25 is smaller than the distance between the upper right and upper left edges of the upward ribs 5 and 5. It has become.

When the panel base material 2 is abutted against the suspension frame 24 according to the modified embodiment (1) and pressed against the suspension frame 24, the panel base material 2 is fixed by the engaging structure as in the case of the above-described embodiment. As shown in 7, the upward ribs 5 and 5 abut on the inclined portions 22R and 22L from the inside, whereby the movement in the butt direction (upward) and the left-right direction is restricted and positioning is performed.

(2) Further, as shown in FIG. 8, for example, the upper end portions of the upward ribs 5 and 5 may be positioned by abutting the inclined portions 26, 26 on the inner and outer sides, that is, on both sides. good.

In the inspection port panel 27 according to the modified mode (2), the apex is at the lower end of the side plate of the suspension frame 28 at a position where the upper ends of the upward ribs 5 and 5 reach when the panel base material 2 is attached. Wedge-shaped (substantially inverted V-shaped) positioning notches 29 and 29 are formed so as to come to each other, and both side edges of the positioning notches 29 and 29 are inclined portions 26 and 26, respectively.

When the panel base material 2 is abutted against the suspension frame 28 according to the modified embodiment (2) and pressed against the suspension frame 28, the panel base material 2 is fixed by the engaging structure as in the case of the above-described embodiment. As shown in 8, each of the upward ribs 5, 5 abuts on the inclined portions 26, 26 so as to be sandwiched from both sides, whereby the movement in the butt direction (upward) and the left-right direction is restricted and positioning is performed. To.

(3) In the above-described embodiment and the modified embodiments (1) to (2), the facing inner surfaces of the upward ribs 5 and 5 have a curved shape along the peripheral surface of the pipe 3, and the pipe 3 has an upward rib 5. It was configured to be attached to the panel base material 2 so as to be fitted between 5 and 5, for example, as shown in FIG. 9, the facing inner surfaces of the upward ribs 30 and 30 were along the peripheral surface of the pipe 3. It may be such that it does not have a curved shape.

In the radiation panel 31 according to the modified mode (3), the upward ribs 30 and 30 are formed so as to form two upright flat plates running in parallel. The facing inner surfaces of the upward ribs 30 and 30 also have a planar shape extending along the vertical direction, the distance between the facing inner surfaces is substantially equal to the outer diameter of the pipe 3, and the pipe 3 is located between the facing inner surfaces. It is designed to be inserted and held. The upward ribs 30 and 30 according to the modified embodiment (3) may also function as positioning protrusions in addition to the function of holding the pipe 3 as in the case of the upward ribs 5 and 5 according to the above embodiment. can. Further, the panel base material 32 according to the modified embodiment (3) has a flat plate shape as a whole, instead of a corrugated plate shape as in the panel base material 2 according to the above embodiment.

(4) In the above-described embodiment and the modified embodiments (1) to (2), the ceiling materials having the features according to the present invention are the inspection port panels 16, 23, 27, but the features according to the present invention are. , It can be applied to parts other than the part where the inspection port is provided.

For example, depending on the layout of the ceiling portion, for example, as shown in FIG. 10, even in the same radiation panel 33, a region D1 in which the pipe 34 can be arranged and a region D2 in which the pipe 34 is difficult to arrange are formed. There is also. In such a case, for example, as in the radiation panel 33 shown in the figure, in the region D1 where the pipe 34 can be arranged, the suspension frame 35 has the same pipe receiving recess as in the radiation panel 1 according to the above embodiment. In the region D2 where it is difficult to arrange the pipe 34, the suspension frame 35 may be formed with the same tapered portion as in the inspection port panel 16 according to the above embodiment. That is, although the suspension frame 35 shown in FIG. 10 is not shown in the figure, the pipe receiving recesses are provided in the upper two places among the four places intersecting the downward ridge 4 in which the pipe 34 is arranged in the panel base material 2. , The structure is such that tapered portions are formed at the lower two places. Further, for example, instead of the tapered portion, the same positioning recess as in the inspection port panel 23 according to the modified mode (1), or the same as in the inspection port panel 27 according to the modified mode (2). A positioning notch or the like may be formed. In other words, the features according to the present invention can also be partially applied to, for example, a radiating panel.

(5) In the above-described embodiment and the modified modes (1) to (4), the ceiling materials having the features according to the present invention are the inspection port panels 16, 23, 27 and the radiation panel 33, but the present invention. Can be applied to ceiling materials such as arbitrary ceiling panels, in addition to those configured for the purpose of radiant air conditioning.

Furthermore, the present invention can be applied not only to ceiling materials but also to interior materials such as wall materials and floor materials.

(6) In the above-described embodiment and the modified modes (1) to (3), the upward ribs 5 and 30 for holding the pipe 3 also function as convex portions for positioning. For example, instead of the upward rib, or separately from the upward rib, a convex portion for positioning may be provided. In particular, for example, in the case of a ceiling panel or the like that is not intended for radiant air conditioning, a configuration for holding the pipe is not required, so a convex portion dedicated to positioning may be provided.

(7) In the above-described embodiment and the modified embodiments (1) to (3), the convex portions for positioning are the upward ribs 5, 5, 30, and 30 that hold the pipe 3 from both sides. The upward ribs 5, 5, 30, and 30 are useful because they can be positioned more reliably in the left-right direction, especially when the tapered portion is sandwiched between them. Even so, the positioning effect in the butt direction and the direction orthogonal to the butt direction can be obtained by abutting the inclined portion.

(8) Further, the configuration of the convex portion for positioning is not particularly limited as long as it can abut on the inclined portion, and is arbitrary, for example, a columnar shape, a vertical plate shape, a block (rectangular parallelepiped) shape, a hemispherical shape, or the like. The shape is possible.

(9) In the above-described embodiment and the modified modes (1) to (4), the side plates of the suspension frames 17, 24, 28, and 35 are cut out into a trapezoidal shape having a hypotenuse, a triangular shape, or the like, so that the inclined portion is formed. However, the configuration of the inclined portion is not particularly limited as long as it can abut on the convex portion. For example, when the convex portion has a shape like a ridge extending long like the upward rib 5 according to the above embodiment, the side plates of the suspension frames 17, 24, 28, and 35 are cut out and formed as described above. Therefore, even an edge-shaped inclined portion that does not spread so much in the thickness direction of the side plate can be surely brought into contact with the convex portion because it is abutted in an intersecting position. When the convex portion has a shape such as a columnar shape or a hemispherical shape, it is desirable that the inclined portion has a planar shape (slope) having a certain degree of spread in order to ensure that the convex portion is in contact with the convex portion.

(10) In the above embodiment, the suspension frame 17 is formed with a trapezoidal tapered portion 18 that tapers downward, and the side edges of the tapered portion 18 are inclined portions 20R and 20L. The shape may be any shape as long as it can form an inclined portion, and may be, for example, a triangular shape (substantially V-shaped), an arc shape, a substantially U-shaped shape, or the like.

Further, the tapered portion 18 according to the above embodiment is formed by cutting out the lower end portion of the side plate in the suspension frame 17, and therefore, as shown in FIG. 5, the protruding end edge (lower end edge) of the tapered portion 18 is the suspension frame. Although it was in the same linear shape as the lower end edge of the side plate in 17, for example, the tapered portion may be formed so as to protrude larger than the lower end of the side plate in the suspension frame, whereby the inclined portion becomes larger by that amount. Therefore, the upward rib 5 of the panel base material 2 can be more easily and surely brought into contact with the mounting position and guided to the mounting position.

(11) Further, in the above-described embodiment and the modified embodiments (1) to (4), upward ribs 5, 5, 30 and 30 having convex portions are formed on the panel base materials 2 and 32 which are plate materials, and the frame material is formed. Inclined portions 20R, 20L, 22R, 22L, 26, 26 were formed on the suspension frames 17, 24, 28, and 35, which are (bare members). It may be a structure in which a portion is formed.

(12) As the panel base material, in addition to the extruded product made of a metal such as aluminum or a resin such as the panel base material 2 according to the above embodiment, for example, an injection molded product made of a resin material or the like. , Metal die-cast products, metal sintered products, sheet metal processed products, and various other materials and modes can be adopted.
