[Modes for carrying out the invention]

[0026] In the following explanation, the up-and-down, left-and-right, and front-and-back directions are defined according to the arrows shown in the diagram.

[0027] In the following section, the ceiling structure 1 according to the first embodiment will be described using Figures 1 to 3.

[0028] Ceiling structure 1 is the structure of the ceiling in a building. In ceiling structure 1, ceiling material (not shown) is supported from the slab 2, which is the building's frame (structural element), via suspension members 10, which will be described later. Figures 1 and 2 show a part of ceiling structure 1 (the part on the slab 2 side).

[0029] Slab 2 is formed by pouring concrete 2b onto the deck plate 2a that constitutes the underside of slab 2. Note that in Figure 1, the concrete 2b of slab 2 is not shown. As shown in Figure 2, an insulating layer is formed on the underside of slab 2 by spraying insulating material 3. By forming an insulating layer, the underside of slab 2 can be given insulating properties. Urethane foam or the like can be used as insulating material 3.

[0030] The ceiling structure 1 comprises a suspension member 10, a fixing bracket 20, a nut 30, a brace 40, and a reinforcing member 100.

[0031] The suspension member 10 is suspended from the slab 2 and supports the ceiling material (not shown). Multiple suspension members 10 are arranged horizontally at predetermined intervals. In the example figure, one suspension member 10 is shown. The suspension member 10 is equipped with an insert 11 and a suspension bolt 12.

[0032] The insert 11 shown in Figures 2 and 3 is fixed to the slab 2. The insert 11 is embedded in the slab 2, except for its lower end. Specifically, the insert 11 is installed so as to penetrate the deck plate 2a vertically before the concrete 2b is poured. In this state, the lower end of the insert 11 protrudes downward from the lower surface of the deck plate 2a. When concrete 2b is poured onto the upper surface of the deck plate 2a in this state, the insert 11 is embedded in the slab 2. The insert 11 according to this embodiment is a female insert with a female thread formed at its lower end, which can secure the suspension bolt 12 described later.

[0033] The suspension bolt 12 supports the ceiling material (not shown). The suspension bolt 12 is formed in an elongated shape and has male threads along its entire length. The suspension bolt 12 is fixed to the insert 11 by fitting its upper end into the female thread of the insert 11. The lower end of the suspension bolt 12 is fixed to the ceiling material's base material (e.g., a ceiling joist support) via a hanger (not shown) or the like.

[0034] The fixing brackets 20 shown in Figures 1 to 3 connect the suspension bolts 12 and the braces 40, which will be described later. The fixing brackets 20 are formed in a long shape in the left-right direction. The fixing brackets 20 are formed in a roughly plate shape with the plate surface facing the front-back direction.

[0035] The fixing bracket 20 is formed from a metal plate-shaped member that has been appropriately bent. In this embodiment, the fixing bracket 20 is formed by combining a pair of plate-shaped members. The pair of plate-shaped members are formed in a symmetrical shape in the front-to-back direction. Note that in Figures 2 and 3, only the rear member of the pair of front-to-back members is shown. The fixing bracket 20 is provided with an insertion hole 21 and a fixing hole 22.

[0036] The through-holes 21 shown in Figures 2 and 3 are holes through which the suspension bolts 12 are inserted. The through-holes 21 are formed to penetrate the fixing bracket 20 in the vertical direction. The through-holes 21 are formed by combining recesses formed on the opposing surfaces of a pair of plate-shaped pieces.

[0037] The fixing holes 22 are holes through which the brace 40 can be fixed. The fixing holes 22 are formed so as to penetrate the fixing bracket 20 in the front-to-back direction. The fixing holes 22 are formed on both the left-to-right sides of the fixing bracket 20. A fastener 23 consisting of a bolt and nut is inserted through the fixing holes 22.

[0038] In this embodiment, the fixing bracket 20 can be attached to the suspension bolt 12 by sandwiching the suspension bolt 12 between a pair of members constituting the fixing bracket 20 and fixing the pair of members with a fixing device 23.

[0039] The nut 30 is fitted onto the suspension bolt 12. The nut 30 is located below the fixing bracket 20. In this embodiment, the fixing bracket 20 and the reinforcing member 100 are fixed to the suspension bolt 12 by fitting the nut 30 onto the suspension bolt 12. A detailed explanation of how each of the above-mentioned members is fixed will be given later.

[0040] The brace 40 shown in Figures 1 and 2 is installed between the fixing bracket 20 and the member on the ceiling material (furring strip) side. The brace 40 is formed in a long shape and is positioned so that its longitudinal direction is inclined with respect to the vertical direction (extending diagonally). In the example shown, the brace 40 is positioned so that it is inclined to the left as it approaches the upper end. The upper end of the brace 40 is fixed to the fixing bracket 20 by a fixing device 23. The lower end of the brace 40 (not shown) is fixed to the ceiling material base material (e.g., furring strip support) via an appropriate member.

[0041] In the ceiling structure 1 described above, for example, if the ceiling material shakes horizontally during an earthquake, the forces generated by the shaking (horizontal and vertical forces) are transmitted to the slab 2 side via the brace 40, suspension members 10, etc.

[0042] In this case, in the ceiling structure 1, a gap is formed between the slab 2 and the upper end (fixing bracket 20) of the brace 40 to form an insulating layer of insulation material 3. In this case, the additional bending moment due to the horizontal force at the upper end of the brace 40 acting on the insert 11 becomes large, so it is necessary to reinforce the insert 11 (i.e., the suspension member 10).

[0043] In this embodiment, the suspension member 10 is reinforced by placing the reinforcing member 100 in the gap. The details of the reinforcing member 100 will be described below.

[0044] The reinforcing member 100 shown in Figures 1 to 3 reinforces the suspension member 10. The reinforcing member 100 is formed in a roughly frustoconical cylindrical shape that opens in the vertical direction. The reinforcing member 100 is made of, for example, metal. The reinforcing member 100 is attached to the suspension bolt 12 of the suspension member 10. The reinforcing member 100 is positioned between the slab 2 and the fixing bracket 20. The reinforcing member 100 comprises a lower part 110, a side part 120, and an upper part 130.

[0045] The lower part 110 constitutes the lower surface of the reinforcing member 100. The lower part 110 is formed in a substantially disc shape with its plate surface oriented vertically. The lower part 110 has mounting holes 111.

[0046] The mounting hole 111 shown in Figure 3 is a hole through which the suspension bolt 12 is inserted. The mounting hole 111 is formed to penetrate vertically through the center of the lower part 110 in a plan view.

[0047] The side portion 120 constitutes the side surface of the reinforcing member 100. The side portion 120 connects the lower portion 110 and the upper portion 130, which will be described later. The side portion 120 is formed to extend upward from the radial outer circumference of the lower portion 110. The side portion 120 is formed in a tapered shape, with its diameter increasing as it extends upward, so that its radial (horizontal) dimension increases. The side portion 120 has an opening 121.

[0048] The opening 121 penetrates the side portion 120 horizontally. The opening 121 is formed in a substantially rectangular shape when viewed horizontally. The opening 121 is formed to extend from the lower end of the side portion 120 to the middle in the vertical direction. Multiple openings 121 are formed. In this embodiment, four openings 121 are formed at equal intervals in the circumferential direction of the side portion 120.

[0049] The upper part 130 constitutes the upper surface of the reinforcing member 100. In this embodiment, the upper part 130 is formed by the upper end of the side part 120. Therefore, the entire upper surface of the reinforcing member 100 is open.

[0050] The reinforcing member 100 has a filling section 140, which is a space partitioned by the lower part 110 and the side part 120. The filling section 140 communicates with the outside space through an opening 121. The thermal insulation material 3 can be filled into the interior of the filling section 140 through the opening 121. A detailed explanation of how to fill the filling section 140 with thermal insulation material 3 will be given later.

[0051] The following describes the procedure for attaching the fixing brackets 20 and reinforcing members 100 to the suspension members 10 during the construction of the ceiling structure 1. Note that the installation of the reinforcing members 100, etc., is carried out before spraying the insulation material 3 onto the slab 2.

[0052] When workers perform installation work on the reinforcing member 100, they first insert the reinforcing member 100 and the nut 30 onto the suspension member 10 (suspension bolt 12) fixed to the slab 2, as shown in Figures 2 and 3. In this case, the worker inserts the reinforcing member 100 and the nut 30 onto the upper end side of the suspension bolt 12 before it is fixed to the insert 11, and then fixes the suspension bolt 12 to the insert 11. The worker also attaches the fixing bracket 20 to the suspension bolt 12 so that it is positioned below the reinforcing member 100 (between the reinforcing member 100 and the nut 30).

[0053] Next, the worker fits the nut 30 onto the suspension bolt 12 so as to press the fixing bracket 20 and the reinforcing member 100 toward the slab 2 side (upwards). In this way, the fixing bracket 20 and the reinforcing member 100 can be fixed to the suspension member 10 by sandwiching them between the slab 2 and the nut 30 from above and below.

[0054] As shown in Figure 2, in this state, the upper end of the fixing bracket 20 is in contact with the lower part 110 of the reinforcing member 100. Also, the upper part 130 of the reinforcing member 100 is in contact with the lower surface of the slab 2.

[0055] After the reinforcing members 100 and the like are installed, the insulation material 3 is sprayed onto the slab 2. As a result, an insulation layer of the insulation material 3 is formed between the slab 2 and the fixing brackets 20 (the area where the reinforcing members 100 are placed) (see Figure 2).

[0056] In this embodiment, the heat insulating material 3 can be passed through the opening 121 formed in the reinforcing member 100 and filled into the interior of the filling section 140. This prevents the formation of the heat insulating layer from being hindered by the presence of the reinforcing member 100, thereby improving heat insulation performance.

[0057] In the example described above, the insulation material 3 was sprayed with the fixing bracket 20 and reinforcing member 100 attached, but the method is not limited to this configuration. For example, the insulation material 3 may be sprayed with only the reinforcing member 100 temporarily fixed to the suspension member 10. In this case, the fixing bracket 20 is attached to the suspension member 10 after the insulation layer has been formed.

[0058] Furthermore, as described above, with the fixing bracket 20 fixed, the upper end of the brace 40 can be fixed to the fixing bracket 20. Although not explained here, the lower end of the brace 40 is fixed to the base material of the ceiling material.

[0059] By providing the reinforcing member 100 as described above, the suspension member 10 can be reinforced, and stress concentration on the suspension member 10 can be suppressed. Specifically, the reinforcing member 100, through its lower part 110 which abuts against the fixing bracket 20, receives the diagonally upward force transmitted from the brace 40, and can also transmit the diagonally upward force to the slab 2 side via its upper part 130. This suppresses stress concentration on the suspension member 10 and prevents deformation of the suspension member 10.

[0060] In this embodiment, the reinforcing member 100 is formed in a tapered frustoconical shape, which allows the upward-sloping force transmitted from the brace 40 to be effectively transmitted to the slab 2.

[0061] The shape of the reinforcing member 100 in the above example is just one example and is not limited to the above example. For example, the shape, size, and number of openings 121 in the reinforcing member 100 are not limited to the above example. The shape, size, and number of openings 121 can be set as appropriate from the viewpoint of the strength of the reinforcing member 100 and the ease of filling with the heat insulating material 3.

[0062] Furthermore, in this embodiment, the upper part 130 is formed by the upper end of the side portion 120, and an example is shown in which the entire upper surface of the reinforcing member 100 is open, but the embodiment is not limited to the above example. For example, the upper part 130 may be formed in a substantially disc shape with holes through which the suspension bolts 12 are inserted.

[0063] Although the first embodiment of the present invention has been described above, the present invention is not limited to the above configuration, and various modifications are possible within the scope of the invention as described in the claims.

[0064] In the following, other embodiments (second to sixth embodiments) of the present invention will be described with reference to Figures 4 to 10. In the following descriptions of the other embodiments, the differences between each embodiment will be explained, and common components will be omitted from the explanation as appropriate.

[0065] First, the reinforcing member 100A according to the second embodiment will be described using Figures 4 and 5.

[0066] As shown in Figure 4, the reinforcing member 100A is formed in a roughly rectangular tubular shape that opens horizontally (left-right direction). Furthermore, the reinforcing member 100A is constructed by combining a pair of members that are divided in a direction perpendicular to the opening direction (front-back direction) within the horizontal direction.

[0067] In the following, the front member of the pair will be referred to as the first member 101A and the rear member as the second member 102A, and each member will be described accordingly. In this embodiment, the first member 101A and the second member 102A, which are formed in a roughly U-shape when viewed in the left-right direction, are combined so as to be symmetrical with respect to each other in the front-rear direction to form a roughly rectangular cylindrical reinforcing member 100A.

[0068] In this embodiment, the first member 101A and the second member 102A are formed to be the same size and shape as each other. Therefore, the following description will focus on the configuration of the first member 101A, and the description of the second member 102A will be omitted.

[0069] The first member 101A is formed from a metal plate-shaped member. The first member 101A comprises a lower part 110A, a side part 120A, and an upper part 130A.

[0070] The lower part 110A constitutes the lower portion of the first member 101A. The lower part 110A is formed in a plate shape with its plate surface oriented vertically. In plan view, the lower part 110A is formed in a substantially rectangular shape. As shown in Figure 5, the lower part 110A has a mounting hole 111 that penetrates in the vertical direction.

[0071] The side portion 120A connects the lower portion 110A and the upper portion 130A, which will be described later. The side portion 120A is formed to extend upward from the front end of the lower portion 110A. The side portion 120A is formed in a plate shape with its surface facing the front-to-back direction. In a front view, the side portion 120A is formed in a roughly trapezoidal (tapered) shape, with the left-to-right dimension increasing as it moves upward.

[0072] The upper part 130A constitutes the upper portion of the first member 101A. The upper part 130A is formed to extend rearward from the upper end of the side part 120A. The upper part 130A is formed in a plate shape with its plate surface oriented vertically. In plan view, the upper part 130A is formed in a substantially rectangular shape. The front-to-back dimension of the upper part 130A is formed to be substantially the same as the front-to-back dimension of the lower part 110A. The left-to-right dimension of the upper part 130A is formed to be larger than the left-to-right dimension of the lower part 110A. As shown in Figure 5, the upper part 130A has a mounting hole 131 that penetrates in the vertical direction.

[0073] The reinforcing member 100A has a filling section 140A formed in it, which is a space partitioned by the lower part 110A, the side part 120A, and the upper part 130A of the first member 101A and the second member 102A. The filling section 140A is open in the horizontal direction (left-right direction).

[0074] The configuration of the first member 101A has been described above. As mentioned above, the second member 102A is generally the same as the first member 101A except that it is arranged symmetrically in the front-rear direction, so its description will be omitted.

[0075] As shown in Figure 4, in this embodiment, a roughly rectangular tubular reinforcing member 100A is constructed by combining the first member 101A and the second member 102A so as to overlap each other. More specifically, in this embodiment, the lower parts 110A of the first member 101A and the second member 102A are overlapped, and the upper parts 130A of the first member 101A and the second member 102A are overlapped. In the example shown, the first member 101A is positioned above the other members.

[0076] The following describes the procedure for attaching the reinforcing member 100A to the suspension member 10.

[0077] The reinforcing member 100A is generally equivalent to the reinforcing member 100 in the first embodiment and is fixed to the slab 2 side via the suspension member 10. In this embodiment, a male insert with a male thread is used as the insert 11A of the suspension member 10. As shown in Figure 5, the portion of the insert 11A with the male thread protrudes from the lower surface of the slab 2.

[0078] As shown in Figure 5, the reinforcing member 100A is fixed to the insert 11A by inserting the insert 11A through the mounting holes 131 in the upper parts 130A of the first member 101A and the second member 102A, and fitting a nut 30 to the part. In this state, the upper part 130A of the first member 101A abuts against the lower surface of the slab 2.

[0079] Furthermore, the reinforcing member 100A has suspension bolts 12 inserted through mounting holes 111 in the lower parts 110A of the first member 101A and the second member 102A. A fixing bracket 20 is attached to the lower side of the lower part 110A of the suspension bolt 12. In this embodiment, the reinforcing member 100A, the fixing bracket 20 and the suspension bolt 12 are fixed to each other by fitting a pair of nuts 30 onto the suspension bolt 12 so as to sandwich each lower part 110A and the fixing bracket 20 from above and below. In this way, in this embodiment, the insert 11A and the suspension bolt 12 are connected via the reinforcing member 100A.

[0080] The reinforcing member 100A described above also produces effects that are generally similar to those described in the first embodiment. That is, the lower part 110A that abuts against the fixing bracket 20 receives the diagonally upward force transmitted from the brace 40, and the diagonally upward force can be transmitted to the slab 2 side via the upper part 130A. This suppresses the concentration of stress on the suspension member 10 (insert 11A). Furthermore, in this embodiment, by bringing the upper surface (upper part 130A) of the reinforcing member 100A, which has a relatively large surface area, into contact with the slab 2, the diagonally upward force transmitted from the brace 40 can be effectively transmitted to the slab 2 side.

[0081] Furthermore, since the side portion 120A of the reinforcing member 100A is formed in a tapered shape, the upward-diagonal force transmitted from the brace 40 can be suitably transmitted to the slab 2 side.

[0082] Furthermore, in this embodiment, when spraying the insulation material 3 onto the slab 2, the insulation material 3 can be filled into the filling section 140A. This makes it possible to suppress the obstruction of the formation of the insulation layer caused by the provision of the reinforcing member 100A, thereby improving the insulation performance.

[0083] Furthermore, since the reinforcing member 100A is formed by combining a pair of members (first member 101A and second member 102A), it is possible to easily manufacture a roughly cylindrical reinforcing member 100A. In this embodiment, since the first member 101A and the second member 102A are formed to be the same size and shape as each other, it is possible to suppress the increase in the number of member types.

[0084] Next, the reinforcing member 100B according to the third embodiment will be described using Figure 6.

[0085] The reinforcing member 100B differs from the reinforcing member 100A according to the second embodiment in that it is a roughly rectangular tubular shape formed integrally rather than being made up of separate parts.

[0086] The reinforcing member 100B has a lower part 110B, a side part 120B, an upper part 130B, and a filling part 140B. The configuration of each of the above parts corresponds to the parts of the reinforcing member 100A (lower part 110A, side part 120A, upper part 130A, and filling part 140A) according to the second embodiment.

[0087] According to the reinforcing member 100B of this embodiment, the number of members can be reduced by integrally forming each part. Furthermore, the reinforcing member 100B provides effects that are generally similar to those described in the above embodiments.

[0088] Next, the reinforcing member 100C according to the fourth embodiment will be described with reference to Figure 7.

[0089] The reinforcing member 100C differs from the reinforcing member 100B according to the third embodiment in that it is not formed in a tapered shape when viewed from the front.

[0090] The reinforcing member 100C has a lower part 110C, a side part 120C, an upper part 130C, and a filling part 140C. The configuration of each of the above parts corresponds to the parts (lower part 110B, side part 120B, upper part 130B, and filling part 140B) of the reinforcing member 100B according to the third embodiment.

[0091] The side portion 120C of the reinforcing member 100C is not formed in a tapered shape, but is formed in a roughly rectangular shape when viewed from the front.

[0092] In this embodiment, a female insert similar to that in the first embodiment is used as the insert 11 of the suspension member 10. Also, in this embodiment, similar to the first embodiment, the fixing bracket 20 and the reinforcing member 100C can be fixed to the suspension member 10 by sandwiching them from above and below with the slab 2 and the nut 30. In this way, in this embodiment, each member can be fixed with a single nut 30.

[0093] According to the reinforcing member 100C of this embodiment, the reinforcing member 100C can be formed with a relatively simple shape. Furthermore, the reinforcing member 100C provides effects that are generally similar to those described in each of the above embodiments.

[0094] Next, the reinforcing member 100D according to the fifth embodiment will be described with reference to Figure 8.

[0095] The reinforcing member 100D differs from the reinforcing member 100C according to the fourth embodiment in that it does not have a filling portion 140C formed therein.

[0096] The reinforcing member 100D has a lower part 110D, a side part 120D, and an upper part 130D. The configuration of each of the above parts corresponds to the parts (lower part 110C, side part 120C, and upper part 130C) of the reinforcing member 100C according to the fourth embodiment.

[0097] The reinforcing member 100D is formed in a solid, approximately rectangular parallelepiped shape. The reinforcing member 100D is made of a material that has heat-insulating properties. Resin or the like can be used as the material for the reinforcing member 100D. However, the material for the reinforcing member 100D is not limited to the above example, and concrete, metal, wood, etc. can also be used. The reinforcing member 100D has holes that penetrate from top to bottom so that the suspension bolts 12 can be inserted through them.

[0098] In the reinforcing member 100D, the portion where a space (filled portion 140C) is formed in the reinforcing member 100C according to the fourth embodiment is closed off. Hereinafter, the closed portion will be referred to as the "solid portion 140D". In the reinforcing member 100D, unlike in which the heat insulating material 3 is filled into the internal space, the formation of the solid portion 140D improves the heat insulating properties.

[0099] Furthermore, the reinforcing member 100D provides effects that are generally similar to those described in each of the above embodiments.

[0100] Next, the reinforcing member 100E according to the sixth embodiment will be described with reference to Figures 9 and 10.

[0101] The reinforcing member 100E differs from the embodiments described above in that it is formed to connect multiple (two in this embodiment) suspension members 10. Furthermore, the reinforcing member 100E reinforces the suspension members 10 by utilizing the member to which the brace 40 is fixed (corresponding to the fixing bracket 20 in the embodiments described above). In the following description of the reinforcing member 100E, the differences from the fixing bracket 20 will be explained, and common components will be omitted from the explanation as appropriate.

[0102] The reinforcing member 100E connects a pair of suspension members 10 that are positioned close to each other, and also fixes the upper end of the brace 40. The reinforcing member 100E is formed from a metal plate-shaped member that has been appropriately bent, similar to the fixing bracket 20. The reinforcing member 100E is also formed by combining a pair of plate-shaped members. The reinforcing member 100E is provided with an insertion hole 21E and a fixing hole 22E.

[0103] The through-hole 21E shown in Figure 10 is a hole through which the suspension bolt 12 is inserted. The through-hole 21E is formed to penetrate the reinforcing member 100E in the vertical direction. The through-hole 21E is formed in pairs, spaced apart in the left-right direction. The through-hole 21E is formed by combining recesses formed on the opposing surfaces of a pair of plate-shaped members.

[0104] The fixing holes 22E are holes through which the brace 40 can be fixed. The fixing holes 22E are formed so as to penetrate the reinforcing member 100E in the front-rear direction. The fixing holes 22E are formed on both the left-right sides of the reinforcing member 100E and between the pair of insertion holes 21E. In other words, in this embodiment, three fixing holes 22E are formed. A fastener 23 consisting of a bolt and a nut is inserted through the fixing holes 22E.

[0105] In this embodiment, a pair of members constituting the reinforcing member 100E sandwich a pair of suspension bolts 12 from the front and back, and the pair of members are fixed together by a fastener 23. This allows the pair of suspension bolts 12 to be connected.

[0106] In this embodiment, as shown in Figure 10, the reinforcing member 100E is fixed by being sandwiched between the insert 11 (female insert) and nut 30 of the suspension member 10. In this state, the upper end of the reinforcing member 100E abuts against the lower end of the insert 11 of the suspension member 10. In this way, the reinforcing member 100E is positioned with a predetermined gap (a gap equal to the protruding dimension of the insert 11) from the lower surface of the slab 2. In addition, in this embodiment, braces 40 are fixed to the fixing holes 22E on both the left and right sides of the reinforcing member 100E.

[0107] As shown in Figures 9 and 10, in this embodiment, a filling portion 140E is formed, which is a space partitioned by the reinforcing member 100E, the slab 2, and the pair of inserts 11. Thus, the reinforcing member 100E is formed to partition a part of the filling portion 140E. In this embodiment, when spraying the heat insulating material 3 onto the slab 2, the heat insulating material 3 can be filled into the filling portion 140E formed as described above.

[0108] Furthermore, in this embodiment, by connecting a pair of suspension members 10, the diagonally upward force transmitted from the brace 40 can be transmitted to the slab 2 side via the pair of suspension members 10 (inserts 11). This allows the force applied to the suspension members 10 to be distributed, and stress concentration on a single suspension member 10 can be suppressed.

[0109] The shape of the reinforcing member 100E in the above example is just one example and is not limited to the above example. For example, in the above example, a member that connects a pair of suspension members 10 and a member to which the brace 40 is fixed are shown to be used in the same way, but each of the above members may be formed separately.

[0110] Furthermore, although the above example shows the upper end of the reinforcing member 100E in contact with the lower end of the insert 11 of the suspension member 10, the invention is not limited to this example. For example, the reinforcing member 100E may be placed at a distance from the insert 11. In this case, the reinforcing member 100E may be fixed to the suspension member 10 by being sandwiched between a pair of nuts 30.

[0111] Furthermore, although the above example shows two suspension members 10 connected by a reinforcing member 100E, the invention is not limited to such an example. For example, the reinforcing member 100E may be formed to connect three or more suspension members 10. In this case, the number of through holes 21E can be appropriately set according to the number of suspension members 10.

[0112] As described above, the reinforcing members 100 to 100E according to each of the above embodiments are Reinforcing members 100 to 100E that reinforce the suspension member 10 that supports the ceiling material, A mounting portion (a portion in which mounting holes 111 and insertion holes 21E are formed) that is attached to the suspension member 10 fixed to the slab 2, A receiving portion (lower part 110-110D, fixing hole 22E) located below the slab 2 and receiving force from the brace 40 extending diagonally upward from the ceiling material, A transmission section (upper part 130 to 130D, where an insertion hole 21E is formed) transmits force from the receiving section (lower part 110 to 110D, where a fixing hole 22E is formed) to the slab 2 side, Between the slab 2 and the receiving portion (lower part 110-110D, portion where fixing holes 22E are formed), there is an insulating portion (filling portion 140-140C, 140E, solid portion 140D) that can provide thermal insulation, It is equipped with the following features.

[0113] This configuration allows for improved thermal insulation while reinforcing the suspension member 10. Specifically, the transmission section (upper part 130-130D, the part where the insertion hole 21E is formed) transmits the diagonally upward force transmitted from the brace 40 to the slab 2 side, thereby suppressing stress concentration on the suspension member 10. Furthermore, the provision of an insulating section (filled section 140-140C, 140E, solid section 140D) improves thermal insulation.

[0114] Furthermore, in the reinforcing members 100 to 100C and 100E according to each of the above embodiments, The aforementioned heat-insulating section (filled sections 140-140C, 140E) The lower surface of the slab 2 has a space into which the insulating material 3 sprayed onto it can be filled, The reinforcing member is An opening (opening 121, filling sections 140A to 140C) is formed which communicates with the aforementioned heat insulating section (filling sections 140 to 140C, 140E) and through which the heat insulating material 3 can pass.

[0115] With this configuration, by forming openings (opening 121, filling sections 140A-140C), it is possible to suppress the obstruction of the formation of the heat insulation layer by reinforcing members 100-100C and 100E, thereby improving heat insulation performance.

[0116] Furthermore, in the reinforcing members 100 to 100D according to each of the above embodiments, The aforementioned transmission section (upper part 130~130D) is It is in contact with the aforementioned slab 2.

[0117] With this configuration, by bringing the transmission section (upper part 130-130D) into contact with the slab 2, the diagonally upward force transmitted from the brace 40 can be directly transmitted to the slab 2.

[0118] Furthermore, in the reinforcing members 100 to 100B according to each of the above embodiments, The receiving portion (lower part 110-110B) is located below the transmission portion (upper part 130-130B), It is equipped with a connecting part (side part 120-120B) that connects the receiving part (lower part 110-110B) and the transmission part (upper part 130-130B), The aforementioned connecting portion (side portion 120~120B) is The structure is tapered, with the horizontal dimension decreasing as it moves from the transmission section (upper part 130-130B) towards the receiving section (lower part 110-110B).

[0119] With this configuration, the tapered shape of the connecting portion (side portion 120-120B) allows for the efficient transmission of the diagonally upward force transmitted from the brace 40 to the slab 2.

[0120] Furthermore, the reinforcing member 100 according to the first embodiment is It is formed in the shape of a frustoconical cylinder that opens in the vertical direction.

[0121] This configuration allows the diagonally upward force transmitted from the brace 40 to be more effectively transmitted to the slab 2.

[0122] Furthermore, the reinforcing members 100A to 100C according to each of the above embodiments are It is formed in a cylindrical shape with the opening (filling section 140A~140C) formed to open horizontally.

[0123] This configuration allows reinforcing members 100A to 100C, which have openings (filling portions 140A to 140C), to be formed in a relatively simple shape. Furthermore, by bringing the upper end surfaces of the cylindrical reinforcing members 100A to 100C into contact with the slab 2, the force applied to the suspension member 10 can be reduced.

[0124] Furthermore, the reinforcing member 100A according to the second embodiment described above is It is composed of a pair of horizontally divided members (first member 101A, second member 102A).

[0125] This configuration makes it easier to manufacture the cylindrical reinforcing member 100A.

[0126] Furthermore, the reinforcing member 100E according to the sixth embodiment described above is Multiple suspension members 10 are formed to be connectable.

[0127] With this configuration, by connecting multiple suspension members 10, it is possible to suppress the concentration of stress on a single suspension member 10.

[0128] The portion in which the mounting hole 111 and the insertion hole 21E are formed is one form of the mounting part. Furthermore, the lower part 110-110D and the portion where the fixing hole 22E is formed represent one form of the receiving part. Furthermore, the side sections 120-120B represent one form of the connection. Furthermore, the upper portion 130-130D and the portion where the insertion hole 21E is formed represent one form of the transmission section. Furthermore, the filled sections 140-140C, 140E, and the solid section 140D represent one form of implementation of the heat insulating section.

[0129] Although various embodiments have been described above, the present invention is not limited to the above configurations, and various modifications are possible within the scope of the invention as described in the claims.

[0130] For example, the shapes of the reinforcing members 100 to 100E in each of the above embodiments are just examples and are not limited to the above examples. For example, the vertical dimensions of the reinforcing members 100 to 100E can be appropriately set according to the position of the upper end of the brace 40 (thickness of the insulation layer), etc. [Explanation of symbols]
