Description

Technical Field

[0001] The present invention relates to a heat insulating material support and a heat insulating structure.

Background Art

[0002] In wooden buildings, it is widely practiced to dispose a heat insulating plate between horizontal members such as joists or girders which are structural members. In this case, usually, a heat insulating material support is locked to a horizontal member such as a girder, and a plate-shaped heat insulating material is held by the heat insulating material support, whereby the plate-shaped heat insulating material is disposed between the horizontal members.

[0003] However, in the above-described conventional heat insulating material support, a load is applied to the heat insulating material support during the construction of the heat insulating material. And, the receiving surface of the heat insulating material support may drop, and a step may occur between the horizontal member and the heat insulating material.

[0004] Techniques for solving such a problem of the step between the horizontal member and the heat insulating material have been proposed. For example, in Patent Document 1, a locking piece that is hooked on a structural member at the base portion of a building, a hanging piece that is bent downward from an end portion of the locking piece, and a pedestal that is bent from a lower end portion of the hanging piece and supports a plate-shaped heat insulating material are provided. In the heat insulating material attachment tool, a support piece is bent from an end portion of the pedestal so as to contact the structural member. Thereby, it is possible to prevent the plate-shaped heat insulating material from being disposed below the target position.

[0005] Further, in Patent Document 2, a heat insulating material support having a vertical plate portion disposed so as to be in close contact with a side end surface of a horizontal member, and a lower horizontal plate portion extending horizontally from a lower surface of the vertical plate portion and supporting a plate-shaped heat insulating material is disclosed. In the heat insulating material support, a reinforcing portion for receiving a load is formed between the vertical plate portion and the lower horizontal plate portion on the lower horizontal plate portion.

Embodiments for Carrying out the Invention

[0020] Hereinafter, embodiments of the present invention will be described. In this specification, unless otherwise specified, "A~B" representing a numerical range means "A or more (including A and greater than A), B or less (including B and less than B)".

[0021] The heat insulating material support according to the embodiment of the present invention (hereinafter, also simply referred to as a support) is used to receive and lock a plate-like heat insulating material when the plate-like heat insulating material is inserted and arranged between horizontal members such as purlins in a method of forming a heat insulating structure of a wooden building.

[0022] The term "horizontal members" as used here refers to all horizontal members used in wooden buildings, provided that insulation material is placed between them. Specifically, horizontal members include girders, joists, beams, purlins, rafters, furring strips, and furring strip hangers. Therefore, the support devices according to this embodiment are not limited to underfloor areas but can also be used in insulation structures such as roofs and ceilings.

[0023] Furthermore, in the various members of the support or heat insulation structure according to this embodiment, "upper surface" refers to the entrance side of the horizontal member into which the heat insulation material is inserted. "Lower surface" refers to the surface opposite to the upper surface. In addition, "side surface (side end surface) of the horizontal member" refers to the surface of the horizontal member facing the space in which the heat insulation material is placed.

[0024] Furthermore, in the support or thermal insulation structure according to this embodiment, "downward" means the direction in which the thermal insulation material is inserted into the horizontal member. Also, "upward" means the direction opposite to the direction in which the thermal insulation material is inserted into the horizontal member.

[0025] For example, "the top surface of the horizontal member" refers to the side on which the top plate is positioned when the support is attached to the horizontal member, and similarly, "the side surface of the horizontal member" refers to the side on which the leg plate is positioned when the support is attached to the horizontal member. Also, "the area below the support plate" refers to the vertically downward side of the support plate.

[0026] The insulation support according to this embodiment will be described below, using a main beam, a typical horizontal structural member, as an example. The insulation support according to this embodiment is not limited to main beams, but can also be applied to other horizontal structural members as mentioned above. For example, it goes without saying that the main beam can also be applied to rafters, furring strips, etc.

[0027] [Embodiment 1] Hereinafter, one embodiment of the present invention will be described in detail. Figure 1 shows a schematic configuration of the support 10 according to this embodiment, where 101 in Figure 1 is a perspective view and 102 in Figure 1 is a cross-sectional view. 201 in Figure 2 is a cross-sectional view showing the support 10 according to this embodiment attached to the main beam 21, and 202 in Figure 2 is a cross-sectional view showing a schematic configuration of the heat insulation structure 100 according to this embodiment.

[0028] As shown in Figures 101 and 102, and Figures 201 and 202, the support member 10 is constructed by bending a strip-shaped member. The support member 10 comprises an upper plate portion 1, a leg plate portion 2, a support plate portion 3, and a locking mechanism 50 having a bent piece 40. The upper plate portion 1 is locked to the upper surface of the main beam 21. The leg plate portion 2 is bent downward from the side end of the upper plate portion 1. The support plate portion 3 supports the lower surface of the insulation material 22. The bent piece 40 is bent from the lower end of the leg plate portion 2 and constitutes a triangular prism-shaped wall with the support plate portion 3 as one side. The side of this triangular prism-shaped wall is composed of the support plate portion 3, as well as the inclined plate portion 41 and the abutment plate portion 42 described later. In the example shown in Figure 2, the insulation material 22 is plate-shaped. However, the shape of the insulation material 22 is not limited to a plate shape.

[0029] Furthermore, as shown in Figure 2, 202, the thermal insulation structure 100 according to this embodiment comprises a support member 10 and a thermal insulation material 22 supported by the support member 10.

[0030] (Upper plate section 1, leg plate section 2, support plate section 3, and reinforcing section 6) In the support 10, the upper plate portion 1 and the leg plate portion 2 form an L shape. The support plate portion 3 is bent and extends from the lower end of the leg plate portion 2. The upper plate portion 1, the leg plate portion 2, and the support plate portion 3 are connected to each other. The leg plate portion 2 is inserted between the main beam 21 and the insulation material 22. The support 10 can also be described as having a Z-shaped configuration in which the upper plate portion 1 and the support plate portion 3 are bent and extend in different directions at the upper and lower ends of the leg plate portion 2, respectively. The upper plate portion 1 extends from the upper end of the leg plate portion 2 along the upper surface of the main beam 21, and the support plate portion 3 extends from the lower end of the leg plate portion 2 along the lower surface of the insulation material 22. Hereinafter, a support 10 with such a configuration may be referred to as a Z-shaped support. Such a Z-shaped support 10 is suitably used, for example, when plate-shaped insulation material 22 is placed on only one side of the main beams 21 arranged at the four corners.

[0031] A reinforcing portion 6 is formed in the bent portion between the leg plate portion 2 and the support plate portion 3. The reinforcing portion 6 is convex toward the insulation material 22 side and is formed to span between the leg plate portion 2 and the support plate portion 3. Due to the action of the reinforcing portion 6, the bent portion between the leg plate portion 2 and the support plate portion 3 is reinforced, and the sagging of the support plate portion 3 can be prevented. Preferably, the reinforcing portion 6 is a rib-like projection formed to span between the leg plate portion 2 and the support plate portion 3. With such a rib-like projection, the rib-like projection acts as a structural element, increasing the strength of the bent portion, and thus preventing the sagging of the support plate portion 3 can be prevented.

[0032] Furthermore, if the reinforcing portion 6 is a rib-like projection, it is preferable that at least the rib-like projection portion formed on the support plate portion 3 extends over a length of at least half the length from the base end to the tip end of the support plate portion 3. This makes the entire support 10 robust and strong.

[0033] The shape of the rib-like protrusions is not particularly limited, as long as they are convex. Furthermore, the rib-like protrusions may be formed so as to be scattered at the corners of the adjacent portions of the leg plate 2 and the support plate 3. Even if the rib-like protrusions are provided only in the minimum portion of the bent section between the leg plate 2 and the support plate 3, the mechanical strength can still be improved.

[0034] In the support 10, the leg plate portion 2 is constructed by bending a strip-shaped member so that the internal angle θ1 with respect to the upper plate portion 1 is a right angle of 90° or an obtuse angle greater than 90°. That is, the internal angle θ1, which is the angle between the upper plate portion 1 and the leg plate portion 2, is a right angle of 90° or an obtuse angle greater than 90°. When the internal angle θ1 is an obtuse angle greater than 90°, the leg plate portion 2 extends from the bent portion at an angle so as to move away from the side surface of the main beam 21. With this configuration, the leg plate portion 2 undergoes elastic deformation from the bent portion between the leg plate portion 2 and the upper plate portion 1. That is, when a force is applied to the leg plate portion 2 in the direction toward the side surface of the main beam 21, a restoring force is generated in the leg plate portion 2 in the direction away from the side surface of the main beam 21 in opposition to that force. The leg plate portion 2 functions as a leaf spring.

[0035] The above function as a leaf spring provides the following effect. When the insulation material 22 is inserted between adjacent beams 21 with multiple support members 10 attached to predetermined positions on both sides of the beams 21, the leg plate portion 2 swings toward the sides of the beams 21 and retracts. As a result, the multiple support members 10 receive the insulation material 22 and support the insulation material 22 with the support plate portion 3. At this time, the leg plate portion 2 is biased with a repulsive stress toward the sides of the insulation material 22 due to elastic deformation, so that the insulation material 22 is sandwiched between the support members 10 on both sides. As a result, even if the width dimension of the insulation material 22 is slightly smaller than the distance between adjacent beams 21, the insulation material 22 can be positioned in the center of the distance between the beams 21, and furthermore, the insulation material 22 can be held in place so as not to shift position.

[0036] The internal angle θ1 is set appropriately according to the restoring force generated in the leg plate portion 2. The internal angle θ1 is, for example, 90° to 100°, preferably 90° to 95°. If the internal angle θ1 is within the above numerical range, when laying it on a horizontal member such as a joist 21, the positioning and fixing of the support 10 to the horizontal member will be stable, an appropriate restoring force will be generated in the leg plate portion 2, and the support 10 will be able to stably hold the insulation material 22.

[0037] Furthermore, in the usage states shown in Figures 201 and 202, the upper plate portion 1 of the support 10 is locked to the upper surface of the main beam 21. Here, "locking" means that when the support 10 is installed on the main beam 21, the upper plate portion 1 remains on the upper surface of the main beam 21, and furthermore, when the insulation material 22 is installed on the support plate portion 3, the support 10 does not fall off the main beam 21. Note that this "locking" state includes not only the state in which the support 10 is merely resting on the main beam 21 via the upper plate portion 1 when the support 10 is installed on the main beam 21, but also, for example, the following state: That is, this "locking" state also includes the state in which the support 10 is fitted and fixed to the main beam 21, or the state in which the support 10 is firmly fixed to the main beam 21.

[0038] In order to firmly fix the support 10 to the main beam 21, the support 10 can be attached to the main beam 21 using nails, claws, adhesive, etc.

[0039] Furthermore, the support 10 may be secured to the main beam 21 by the upper plate portion 1 only. Here, "secured by the upper plate portion 1 only" means that only the upper plate portion 1 is in contact with the main beam 21, and the leg plate portion 2 is not in contact with the main beam 21. In this state, the leg plate portion 2, which is not in contact with the main beam 21, only serves to position the support 10 when it is installed on the main beam 21. Note that the above "contact" also includes "fixing" and / or "adhesion".

[0040] The support plate portion 3 is a piece that bends and extends from the leg plate portion 2. In the configuration shown in Figures 1 and 2, the support plate portion 3 is bent from the lower end of the leg plate portion 2. The support plate portion 3 may be bent from the middle of the leg plate portion 2, but preferably, the support plate portion 3 is bent from the lower end of the leg plate portion 2. The support plate portion 3 extends from the lower end of the leg plate portion 2 toward the space where the insulation material 22 will be placed. The insulation material 22 will be placed on the upper surface of the support plate portion 3. In actual use, at least two support members 10 are locked to the main beam 21 so that they face each other, and the insulation material 22 is pressed and placed on the two opposing support plate portions 3. Then, by placing a board on top of the insulation material 22, the insulation structure of the house can be easily constructed.

[0041] Here, with respect to the support plate portion 3, "extending toward the space where the insulation material 22 is placed" can also be said to mean that, in the leg plate portion 2, it extends in the opposite direction to the direction in which the upper plate portion 1 extends. Before the insulation material 22 is placed and with the support 10 locked to the main beam 21, the angle θ2 between the leg plate portion 2 and the support plate portion 3 is preferably 75° to 90°.

[0042] The length of the upper plate portion 1 that is secured to the main beam 21 is not specifically defined, but is preferably in the range of 3% to 100% of the width dimension of the main beam 21, more preferably in the range of 5% to 75%, and even more preferably in the range of 10% to 50%.

[0043] The length of the leg plate portion 2 is defined as the length from the upper end of the leg plate portion 2 to the point where the insulation material support surface of the support plate portion 3 intersects with the leg plate portion 2. If the support plate portion 3 has a reinforcing portion 6, the insulation material support surface is the upper surface of the reinforcing portion 6. In the configurations shown in Figures 101 and 102, this length is defined as the length from the upper end to the lower end of the leg plate portion 2. When the insulation material 22 is pressed and positioned between the main beams 21, in order to ensure secure locking between the main beams 21, the length of the leg plate portion 2 is preferably 96.0% to 99.9% of the thickness of the insulation material 22, and more preferably 98.0% to 99.9%. This necessitates pushing the insulation material 22 in to prevent a step between the main beam 21 and the insulation material 22, causing the insulation material 22 to compress slightly. Simultaneously, the support plate portion 3 constituting the folded piece 40 moves downward, resulting in the inclined plate portion 41 moving towards the main beam 21. As a result, the contact plate portion 42 comes into close contact with the main beam 21, generating a large reaction force. In this way, the leaf spring action of the contact plate portion 42 on the main beam 21 ensures that the insulation material 22 is securely locked between the main beams 21.

[0044] Furthermore, the length of the support plate 3 can be set appropriately, taking into consideration the weight of the insulation material 22, etc.

[0045] The thickness of the support member 10, that is, the thickness of the strip-shaped member constituting the support member 10, is preferably 0.1 mm to 2.0 mm, more preferably 0.2 mm to 0.8 mm, and even more preferably 0.25 mm to 0.5 mm. By having the thickness within the above numerical range, the proportion of the volume of the support member 10 in the thermal insulation structure is reduced, thereby reducing the risk of thermal deficiencies in the thermal insulation structure and enabling the realization of a superior thermal insulation structure.

[0046] (locking mechanism 50) In the support 10, when a load is applied to the insulation material 22, the support plate portion 3, which is the receiving surface for the insulation material 22, may move downward, causing the support 10 to deform. The main downward movement is that the support plate portion 3 bends downward from the bent portion between the leg plate portion 2 and the support plate portion 3. As a result of this movement of the support plate portion 3, the insulation material 22 sinks downward, creating a step between the main beam 21 and the insulation material 22. To eliminate this step, the support 10 according to this embodiment is equipped with a locking mechanism 50 that prevents the downward movement of the support plate portion 3.

[0047] The specific configuration of the locking mechanism 50 (bent piece 40) will be described in more detail with reference to 101 and 102 in Figure 1 and 201 and 202 in Figure 2. As shown in these figures, the bent piece 40 has a support plate portion 3, an inclined plate portion 41, and a contact plate portion 42. The support plate portion 3 is bent from the leg plate portion 2 and extends along the lower surface of the insulation material 22. The inclined plate portion 41 is bent downwards and extends from the tip of the support plate portion 3. The contact plate portion 42 is bent upwards from the inclined plate portion 41. The bent piece 40, consisting of the support plate portion 3, the inclined plate portion 41, and the contact plate portion 42, forms a triangular prism-shaped wall. This triangular prism-shaped wall extends along the side surface of the main beam 21.

[0048] As shown in Figures 101 and 102, the abutment plate portion 42 extends vertically upward (in the opposite direction to gravity) relative to the connection portion with the inclined plate portion 41. Therefore, the shape of the wall is a triangular prism with a right-angled triangle as its base. Here, the support plate portion 3 and the inclined plate portion 41 are connected. Also, the inclined plate portion 41 and the abutment plate portion 42 are connected. On the other hand, the abutment plate portion 42 and the support plate portion 3 are not directly connected. Furthermore, the abutment plate portion 42 is in surface contact with the side surface of the main beam 21.

[0049] In the thermal insulation support described in Patent Document 2, the reinforcing portion is composed of a triangular wall having an inclined plate portion extending at an acute angle with the same width from the tip of the lower horizontal plate portion, and a second vertical plate portion extending upward from the inclined plate portion. In the reinforcing portion of the thermal insulation support described in Patent Document 2, the second vertical plate portion abuts against the side wall surface of the main beam, thereby preventing the plate-shaped thermal insulation material from being positioned below the intended location. However, in the thermal insulation support described in Patent Document 2, the abutment of the second vertical plate portion against the side wall surface of the main beam may be insufficient, leaving room for improvement.

[0050] Here, according to the support 10 of this embodiment, as shown in 102 of Figure 1 and 201 of Figure 2, the tip of the bent piece 40 is located on the side of the main beam 21 relative to the imaginary vertical line L below the leg plate 2. The contact plate portion 42 is the tip of the bent piece 40. The locking mechanism 50 prevents the downward movement of the support plate portion 3 by having the tip of the bent piece 40, i.e., the contact plate portion 42, contact a part of the main beam 21. In the bent piece 40 of the heat insulating structure 100, the locking mechanism 50 makes surface contact between the contact plate portion 42 and the side surface of the main beam 21 and has a biasing force that biases the contact plate portion 42 toward the side surface of the main beam 21.

[0051] When manufacturing the insulation structure 100, as shown in 201 of Figure 2, the support member 10 is set on the main beam 21 such that the contact plate portion 42 is inclined and contacts the side surface of the main beam 21. In this state, when the insulation material 22 is placed on the support member 10 and pressed down, a reaction force is formed. More specifically, in the insulation structure 100 shown in 202 of Figure 2, when a downward load is applied to the insulation material 22, the support plate portion 3 receives the load from the insulation material 22. The load received by the support plate portion 3 is then distributed to the inclined plate portion 41 and transmitted to the main beam 21 via the contact plate portion 42. As a result, in the insulation structure 100, a reaction force acts on the main beam 21, and this reaction force supports the load from the insulation material 22.

[0052] Here, in the support 10, the inclined plate portion 41 extends from the support plate portion 3 toward the main beam 21 such that the contact plate portion 42 is positioned on the main beam 21 side of the imaginary vertical line L in the downward direction. As a result, as shown in 201 of Figure 2, when the support 10 is locked to the main beam 21, the contact plate portion 42 reliably contacts the side surface of the main beam 21, and a leaf spring action is generated between the bent piece 40 and the main beam 21. Due to this leaf spring action, the support plate portion 3 is locked to the main beam 21, thereby preventing the support plate portion 3 from moving downward. As a result, even when a load is applied to the insulation material 22, the support 10 can support the insulation material 22 without any step difference with the main beam 21.

[0053] Furthermore, the thermal insulation support described in Patent Document 1 has a locking piece that hooks onto a structural member of the building's foundation, a hanging piece bent downward from the end of the locking piece, and a base bent from the lower end of the hanging piece to support the thermal insulation, with the support piece bent from the end of the base. In the thermal insulation support described in Patent Document 1, for example, the support piece is formed by bending downward from both ends of the base that sandwich the hanging piece. That is, the direction in which the hanging piece bends relative to the base and the direction in which the support piece bends relative to the base are different. In such a configuration, if the thermal insulation support is manufactured by bending a single plate-like object (metal plate), it is necessary to manufacture the support piece by bending it in a direction perpendicular to the bending direction of the hanging piece relative to the base, which complicates the bending direction and increases the processing cost of the support. Furthermore, the required area of ​​metal plate used increases, reducing the design freedom of the thermal insulation support. On the other hand, according to the support 10 of this embodiment, the shape design of the support 10 can be achieved simply by bending a single plate-like object (metal plate) in a certain direction, thus significantly reducing the processing cost of the support 10.

[0054] In the configurations shown in Figures 101 and 102, the bent piece 40 forms a triangular prism-shaped wall with the support plate portion 3 as one side. However, the shape of the wall formed by the bent piece 40 can be columnar as long as it achieves the effects described above. Preferably, the shape of the wall is a rectangular prism with a rectangular cross-section.

[0055] As long as a leaf spring action occurs between the bent piece 40 and the main beam 21 and the above effect is achieved, the amount of displacement of the contact plate portion 42 toward the main beam 21 relative to the imaginary line L is not particularly limited. Preferably, the contact plate portion 42 of the bent piece 40 is positioned on the main beam 21 side of the imaginary line L by more than 0 mm and less than or equal to 2 mm. This ensures that the contact plate portion 42 reliably contacts the side surface of the main beam 21, and the locking function of the locking mechanism 50 made of the bent piece 40 works effectively. If the contact plate portion 42 is positioned on the main beam 21 side of the imaginary line L by more than 2 mm, the contact plate portion 42 will contact the side surface of the main beam 21, and the leaf spring action generated between the contact plate portion 42 and the main beam 21 will become too strong. As a result, when placing the heat insulating material 22 on the support plate portion 3 of the support 10 and pressing the heat insulating material 22 in, a considerable amount of force is required, which tends to reduce work efficiency.

[0056] Furthermore, in the support 10 according to this embodiment, the location where the contact plate portion 42 contacts the main beam 21 may be any side surface, and is not limited to the configurations shown in 201 and 202 of Figure 2.

[0057] The upper vertical tip of the contact plate portion 42 may be at the same height as the support plate portion 3, or it may be located below or above the support plate portion 3. If the upper vertical tip of the contact plate portion 42 is located above the support plate portion 3, a part of the contact plate portion 42 may overlap with the leg plate portion 2. When the contact plate portion 42 and the leg plate portion 2 overlap, the contact plate portion 42 and the leg plate portion 2 will not easily bend even when the support plate portion 3 is subjected to a load. Therefore, the support plate portion 3 is less likely to bend downward, and the insulation material 22 is less likely to sink downward.

[0058] For example, a modified example of the support 10 is the support 10A shown in 301 and 302 of Figure 3. In the support 10A, the contact plate portion 42A extends vertically upward (in the opposite direction to gravity) relative to the inclined plate portion 41. In 302 of Figure 3 and 401 of Figure 4, the tip of the bent piece 40A, i.e., the contact plate portion 42A, is located on the side of the main beam 21 relative to the imaginary line L in the downward vertical direction of the leg plate portion 2. The vertically upward tip of the contact plate portion 42A is located above the position of the support plate portion 3.

[0059] In the support member 10A shown at 401 in Figure 4 and the thermal insulation structure 100A shown at 402 in Figure 4, the inclined plate portion 41 extends from the support plate portion 3 toward the main beam 21 such that the contact plate portion 42A is located toward the main beam 21 than the imaginary vertical line L in the downward direction. Furthermore, the vertically upward tip of the contact plate portion 42 is located above the support plate portion 3. As a result, in the thermal insulation structure 100A, even when a load is applied to the thermal insulation material 22, the support member 10A can support the thermal insulation material 22 without any step difference with the main beam 21'.

[0060] As shown in Figure 4, 402, when the thickness of the main beam 21' is thinner than the thickness of the insulation material 22, when a downward load is applied to the insulation material 22, the support plate portion 3 receives the load from the insulation material 22, and a force acts on the support 10A that bends the support plate portion 3 downward. Then, the component of the load from the insulation material 22 is transmitted to the inclined plate portion 41, and a force acts on the support 10A that bends the contact plate portion 42A and the leg plate portion 2 with the lower side end 21'a of the main beam 21' as the fulcrum. At this time, since the contact plate portion 42A and the leg plate portion 2 overlap, they have stronger resistance to the load from the insulation material 22 compared to when the bending force with the lower side end 21'a as the fulcrum acts only on the leg plate portion 2. In the configuration shown in 402 of Figure 4, for example, if the upper vertical tip of the contact plate portion 42A is located below the support plate portion 3, a bending force acts only on the leg plate portion 2, with the lower side end 21'a as the fulcrum.

[0061] [Embodiment 2] Further embodiments of the present invention will be described below. For the sake of clarity, components having the same function as those described in the above embodiments will be denoted by the same reference numerals, and their descriptions will not be repeated.

[0062] Figure 5 shows a schematic configuration of the support 10B according to this embodiment, where 501 is a perspective view and 502 is a cross-sectional view. As shown in 501 and 502 of Figure 5, the support 10B according to this embodiment differs from Embodiment 1 in that it has two leg plate portions 2.

[0063] As shown in Figures 501 and 502, the support 10B is equipped with two leg plate portions 2. The two leg plate portions 2 are formed by bending from two opposing side walls of the upper plate portion 1A. In other words, the upper plate portion 1A is sandwiched and connected between the two leg plate portions 2. The support 10B forms a (vertically inverted) U shape with the upper plate portion 1A and the two leg plate portions 2. Hereinafter, a support of this shape may be referred to as a U-shaped support. In such a U-shaped support 10B, a support plate portion 3 extends horizontally from the lower end of each of the two leg plate portions 2. The two support plate portions 3 provided at the lower end of each of the two leg plate portions 2 extend in opposite directions.

[0064] Furthermore, a bent piece 40 is provided for each of the two support plate sections 3 so as to form a triangular prism-shaped wall with the support plate section 3 as one side. The specific configuration of the bent piece 40 is the same as that of the support 10 according to Embodiment 1, so a description will be omitted. As shown in 502 of Figure 5, in the support 10B, the two bent pieces 40 are provided so as to be symmetrical with respect to the imaginary line X as the axis.

[0065] The support member 10B according to this embodiment is preferably used, for example, when plate-shaped insulating material is arranged on both sides of the main beam. In this case, the support member 10B is configured to clamp the main beam 21 with two leg plate portions 2, and these two leg plate portions 2 are locked to the main beam 21.

[0066] The support 10B can be manufactured separately from the support 10 according to Embodiment 1. However, it is possible to manufacture the support 10 from the support 10B according to this embodiment. More specifically, as shown in Figures 501 and 502, in the support 10B, the upper plate portion 1A has a notch 11 (third notch) made of a thin-walled portion. The thin-walled portion of the notch 11 is, for example, a V-shaped groove. The upper plate portion 1A is then divisible into pieces 1aa and 1ab via the notch 11.

[0067] Because the notch 11 is formed in this way, the U-shaped upper plate portion 1A can be divided at the construction site as needed to manufacture two Z-shaped support members. The divided Z-shaped support members can then be used to position them at the four corners of the main beam. Furthermore, since only one type of support member 10B needs to be manufactured, the productivity of the support members is excellent. Note that the notch 11 is not limited to thin-walled sections such as V-shaped grooves, but can be any structure that allows the upper plate portion 1 to be divided. For example, the notch 11 may be a slit-like structure that penetrates the upper plate portion 1 vertically.

[0068] [Embodiment 3] Further embodiments of the present invention will be described below. For the sake of clarity, components having the same function as those described in the above embodiments will be denoted by the same reference numerals, and their descriptions will not be repeated.

[0069] Figure 6 shows a schematic configuration of the support 10C according to this embodiment, where 601 is a perspective view and 602 is a cross-sectional view. As shown in 601 and 602 of Figure 6, the support 10C differs from Embodiment 2 in that the support plate portion 3 has a piercing piece 12a (first piercing piece) and the upper plate portion 1B has a piercing piece 13a (second piercing piece). It goes without saying that the piercing pieces 12a and 13a are also applicable to the support according to Embodiment 1.

[0070] In the support 10C, the support plate portion 3 is provided with a notch 12b (first notch). The piercing piece 12a (first piercing piece) is formed by raising the notch 12b. Specifically, the piercing piece 12a is formed by raising the notch 12b almost vertically toward the lower surface of the insulation material, and its tip is sharp. The piercing piece 12a is embedded in the surface of the insulation material and attached.

[0071] With this configuration, when attaching the insulation material to the support fixture secured to the main beam, the piercing piece 12a bites into the underside of the insulation material. Therefore, even if the support plate portion 3 is subjected to a load and bends downward, the insulation material can be held in place without slipping off.

[0072] Furthermore, in the support 10C, the upper plate portion 1B is provided with a notch 13b (second notch), and the piercing piece 13a (second piercing piece) is formed by raising the notch 13b. Specifically, the piercing piece 13a is formed by raising the notch 13b almost vertically toward the upper surface of the main beam, and its tip is sharp. The piercing piece 13a is fitted into the upper surface of the main beam.

[0073] With this configuration, when attaching the support 10C to the main beam, the support 10C can be firmly fixed to the main beam by driving the piercing piece 13a into the upper surface of the main beam. Therefore, the support 10C is less likely to come off the main beam during construction, thus improving work efficiency.

[0074] Furthermore, even for joists with a curved cross-section along the width direction, the support member 10C can be firmly fixed to the joist by driving the piercing piece 13a into the upper surface of the joist. After driving, the support member 10C is less likely to fall off the joist.

[0075] Note that the notches 12b and piercing pieces 12a, and the notches 13b and piercing pieces 13a are not limited to the configurations shown in 601 and 602 of Figure 6.

[0076] Furthermore, the U-shaped support according to this embodiment is not limited to a configuration that includes piercing pieces 12a and 13a as shown in 601 and 602 of Figure 6. The U-shaped support may be fitted from the upper surface of the main beam and the main beam may be clamped between two leg plate portions 2. In this case, the angle between the upper plate portion 1B and the leg plate portion 2 is preferably 90° to 100°, and more preferably 90° to 95°, so that the U-shaped support can securely clamp the main beam.

[0077] [Embodiment 4; Modified versions applicable to the support devices according to Embodiments 1-3] In embodiments 1 to 3, the bent piece constitutes a triangular prism-shaped wall. However, the bent piece is not limited to this; it is sufficient if it is bent from the lower end of the leg plate and constitutes a prism-shaped wall with the support plate on one side. Figure 7 shows a schematic configuration of the support 10D according to this embodiment, where 701 in Figure 7 is a perspective view and 702 in Figure 7 is a cross-sectional view.

[0078] As shown in Figure 7, the support 10D differs from embodiments 1 to 3 in that the bendable piece 40D provided on the locking mechanism 50A constitutes a rectangular prism-shaped wall. More specifically, the bendable piece 40D consists of a support plate portion 3, a vertical plate portion 43, a horizontal plate portion 44, and a contact plate portion 42D. The support plate portion 3 is bent from the leg plate portion 2 and extends along the lower surface of the insulation material. The vertical plate portion 43 is bent vertically downward from the tip of the support plate portion 3. The horizontal plate portion 44 is bent vertically from the tip of the vertical plate portion 43 toward the leg plate portion 2. The contact plate portion 42D is bent vertically upward from the tip of the horizontal plate portion 44. Furthermore, as shown at 702 in Figure 7, the contact plate portion 42D is the tip of the bent piece 40D and is located on the main beam side of the imaginary line L in the vertical direction below the leg plate portion 2. The tip of the contact plate portion 42D in the vertical direction is also located on the main beam side of the imaginary line L.

[0079] The folded section 40D forms a rectangular prism-shaped wall with a support plate section 3, a vertical plate section 43, a horizontal plate section 44, and abutment plate section 42D. Here, the support plate section 3 and the vertical plate section 43 are connected. The vertical plate section 43 and the horizontal plate section 44 are also connected. Furthermore, the horizontal plate section 44 and the abutment plate section 42D are connected. On the other hand, the abutment plate section 42D and the support plate section 3 are not connected. The upper vertical tip of the abutment plate section 42D is spaced apart from the support plate section 3.

[0080] When a downward load is applied to the insulation material, the locking mechanism 50A prevents the support plate portion 3 from moving downward by causing the contact plate portion 42D of the bent piece 40D to contact the side surface of the main beam. Therefore, even when a load is applied to the insulation material, the support 10D can support the insulation material without any step difference with the main beam.

[0081] (Regarding the support devices related to Embodiments 1 to 4) The support devices according to Embodiments 1 to 4 are preferably in the shape of a folded strip-shaped plate member. This eliminates the presence of outward protrusions from the plate member constituting the support device. Therefore, by arranging the support devices in a row with the main beam in between, a large number of support devices can be stored and transported without any gaps, making the handling of the support devices very efficient.

[0082] Furthermore, the support members according to Embodiments 1 to 4 are preferably formed by punching and bending metal plates, regardless of whether they are Z-shaped or U-shaped. By forming the support members by such processing, there is no waste of material, and the support members can be manufactured efficiently.

[0083] In a preferred form of construction using the support structure formed in this way, first, the support structures are installed at appropriate intervals between the joists which are installed parallel to each other. Then, plate-shaped insulation material is installed on the support plate portion of the support structure. After that, board materials such as flooring and subfloor materials are installed on the joists.

[0084] The material of the support according to Embodiments 1 to 4 is not particularly limited, as long as it achieves the effects described above. The material of the support may be a metal plate, synthetic resin, etc. If the material of the support is a metal plate, the support can be manufactured by metal casting and welding, etc. If the material of the support is a synthetic resin, the support can be manufactured by methods such as injection molding of synthetic resin or thermoforming of synthetic resin sheets. From the viewpoint of productivity, rigidity, and the ability to reduce thickness, it is most preferable that the support according to Embodiments 1 to 4 be formed from a metal plate.

[0085] Furthermore, the plate-shaped insulating material used in the insulating structure equipped with a support is not particularly limited, and examples include plate-shaped insulating material made of synthetic resin foam, plate-shaped vacuum insulating material made of glass fiber or synthetic fiber, etc. Among the above insulating materials, plate-shaped insulating material made of synthetic resin foam is preferred because it is lightweight, has high rigidity, excellent water resistance and pressure resistance, has high thermal insulation performance, and its thickness can be easily changed by processing. Examples of synthetic resin foams suitable for insulating materials include closed-cell synthetic resin foams such as polystyrene resin foam, polyethylene resin foam, polypropylene resin foam, polyurethane resin foam, and phenolic resin foam. Among these synthetic resin foams, a more preferred form of the synthetic resin foam is, in particular, a polyolefin resin extruded foam molded article made of a polystyrene resin, a polyethylene resin, or a polypropylene resin, due to its high thermal insulation properties and low water absorption. In this more preferred form, the synthetic resin foam may be a polystyrene resin foam particle molded article. In this more preferred form, the polystyrene resin, polyethylene resin, or polypropylene resin has high recyclability.

[0086] Furthermore, "plate-shaped" means that the basic shape is a rectangular prism. "Plate-shaped" also includes shapes with rounded corners or chamfered corners, while still being based on a rectangular prism shape. Additionally, the surface of the insulation material may have irregularities. For plate-shaped insulation materials, those with a thickness of 15mm to 300mm, a length of 600mm to 4,000mm, and a width of 200mm to 2,000mm are preferably used.

[0087] The present invention is not limited to the embodiments described above, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention. [Explanation of Symbols]
