Description

[Technical Field]

[0001] The present invention relates to a support, a mounting structure for a ceiling-mounted device, and a method for installing the same. [Background technology]

[0002] As shown in Figures 7 and 8, a test installation was carried out in which a relatively heavy ceiling-mounted device 100, such as a ventilation fan, was attached to a joist 101 using support brackets 102. The support bracket 102 has an L-shape in which a first surface 102a that contacts the side surface of the joist 101 is bent at a 90-degree angle to a second surface 102b that contacts the underside of the ceiling-mounted device 100. To install the ceiling-mounted device 100 using these support brackets 102, four support brackets 102 must first be fixed in specified positions with screws 105, and then the installer must lift the ceiling-mounted device 100 and place it on the four support brackets 102.

[0003] Patent Document 1 discloses a relatively lightweight duct ventilation fan that can be installed above the ceiling. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 5-10934 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the trial installation described above, because the support bracket 102 was used, when the ceiling-space mounting device 100 was lifted and placed on the support bracket 102, the ceiling-space mounting device 100 hit the support bracket 102, making it difficult to smoothly install the ceiling-space mounting device 100. Furthermore, the structure disclosed in Patent Document 1 is a mounting structure for mounting a relatively lightweight ventilation fan in the ceiling, and is not suitable for installing a relatively heavy ventilation fan in the ceiling.

[0006] In view of the above circumstances, an object of the present invention is to provide a support that allows even a relatively heavy ceiling-mounted device to be smoothly mounted in the ceiling, an installation structure for the ceiling-mounted device, and an installation method thereof. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, the support device according to the present invention is a support device for supporting an object to be supported by a square bar-shaped material, and has a pair of opposing surface portions facing side portions of the square bar-shaped material, a connecting surface portion connecting the pair of opposing surface portions on the upper surface portion of the square bar-shaped material, and a protruding piece portion extending from a lower end side of one of the opposing surface portions located on the installation side of the object to a fixing point side on the underside of the object to be supported, a fastening insertion hole through which a fastening member for fastening the support tool to the square bar-shaped material is passed is formed in at least one surface portion of the pair of opposing surface portions and the connecting surface portion; The projecting piece is characterized in that a fixing insertion hole is formed through which a fixing member for fixing the supported object to the support tool is passed (this configuration is referred to as a first support tool in this section).

[0008] With the first support, the U-shaped portion formed by the pair of opposing surfaces and the connecting surface can be hooked onto the square bar-shaped material and the position can be adjusted by sliding, so that the object to be supported is prevented from hitting the first support when the object to be supported is attached, and the installation work can be carried out smoothly. Also, since the connecting surface is positioned on the upper surface of the square bar-shaped material, the posture of the protruding piece is automatically determined.

[0009] The fastening insertion hole may be formed in one of the opposing surface portions located on the installation side of the supported object and in the connecting surface portion (this configuration is referred to as a second support tool in this section).

[0010] In the first support, the fixing insertion hole may be an elongated hole that is long in the extension direction of the square bar-shaped material (this configuration will be referred to in this section as a third support). In the second support, the fixing insertion hole may be an elongated hole that is long in the extension direction of the square bar-shaped material (this configuration will be referred to in this section as a fourth support). Even if there is some misalignment between the fixing insertion hole and the location on the supported object where the fixing member is fixed, the fixing insertion hole is an elongated hole, so that the fixing member can be passed through the fixing insertion hole to fix the supported object.

[0011] The mounting structure for a ceiling-space mounting device according to this invention is a mounting structure for a ceiling-space mounting device using the first and third supports, and is characterized in that two supports are fastened to each of two of the square bar-shaped materials arranged parallel to each other in the ceiling space by the fastening members passed through the fastening insertion holes, so that the ceiling-space mounting device is supported by the protruding piece portions of a total of four supports, and the ceiling-space mounting device is fixed to the supports by the fixing members passed through the fixing insertion holes (this mounting structure is referred to as a first mounting structure in this section).

[0012] In the first mounting structure, the ceiling-mounting device can be supported by the two square rods using four supports, and the supports can be fastened to the square rods using the fastening members by using the fastening insertion holes at locations that facilitate fastening.

[0013] The mounting structure for a ceiling-space mounting device according to the present invention is a mounting structure for a ceiling-space mounting device using the second and fourth supports, in which one support is fastened to each of the two square bar-shaped materials arranged parallel to each other in the ceiling space by the fastening member passed through the fastening insertion hole in the opposing surface portion, while another support is fastened to each of the two square bar-shaped materials by the fastening member passed through the fastening insertion hole in the connecting surface portion, so that the ceiling-space mounting device is supported by the protruding piece portions of a total of four supports, and the ceiling-space mounting device is fixed to the supports by the fixing member passed through the fixing insertion hole (this mounting structure is referred to as a second mounting structure in this section).

[0014] In the second mounting structure, the ceiling-surface mounting device can be supported by the two square bar-shaped materials using four support members. When fastening the support members to the square bar-shaped materials with the fastening members, the fastening insertion holes in the facing surface portions of two of the four support members are used to facilitate the fastening work, and the fastening insertion holes in the connecting surface portions of the other two support members are used. Even if the facing surface portions of the other two support members are blocked by the ceiling-surface mounting device, the fastening members can pass through the fastening insertion holes in the connecting surface portions.

[0015] The method for constructing the mounting structure for the ceiling-mounted mounting device according to the present invention is a method for constructing the first mounting structure, comprising: fastening one support to each of two of the square bar-shaped materials arranged parallel to each other with the fastening members; and temporarily positioning one support to each of the two square bar-shaped materials; After supporting one side of the ceiling-mounted device with the protruding piece portions of the two fastened supports, the two temporarily placed supports are slid toward the other side of the ceiling-mounted device, and the other side of the ceiling-mounted device is supported with the protruding piece portions of these two supports; the two supports supporting the other side of the ceiling-mounting device are fastened to the square bar-shaped material by the fastening members passed through the fastening insertion holes; The ceiling mounting device is fixed to the support by the fixing members passed through the fixing insertion holes of the protruding piece portions of a total of four of the support.

[0016] With this method, after one side of the ceiling-space mounting device is supported by the protruding piece portions of the two supports, the two temporarily positioned supports are slid toward the other side of the ceiling-space mounting device, and the other side of the ceiling-space mounting device is supported by the protruding piece portions of these two supports.This prevents the ceiling-space mounting device from hitting the supports when installing the ceiling-space mounting device, and allows for smooth installation work.

[0017] The installation method for installing the installation structure for the ceiling-mounted installation device according to the present invention is an installation method for installing the second installation structure, in which one support is fastened to each of the two square bar-shaped materials arranged parallel to each other by the fastening members passed through the fastening insertion holes of the opposing surface portions, while one support is temporarily placed on each of the two square bar-shaped materials, After supporting one side of the ceiling-mounted device with the protruding piece portions of the two fastened supports, the two temporarily placed supports are slid toward the other side of the ceiling-mounted device, and the other side of the ceiling-mounted device is supported with the protruding piece portions of these two supports; the two supports supporting the other side of the ceiling-mounting device are fastened to the square bar-shaped material by the fastening members passed through the fastening insertion holes of the connecting surface portions; The ceiling mounting device is fixed to the support by the fixing members passed through the fixing insertion holes of the protruding piece portions of a total of four of the support.

[0018] With this method, after one side of the ceiling-space mounting device is supported by the protruding piece portions of the two supports, the two temporarily positioned supports are slid toward the other side of the ceiling-space mounting device, and the other side of the ceiling-space mounting device is supported by the protruding piece portions of these two supports.This prevents the ceiling-space mounting device from hitting the supports when installing the ceiling-space mounting device, and allows for smooth installation work. [Effects of the Invention]

[0019] The present invention has the effect of enabling even a relatively heavy ceiling-mounting device to be smoothly mounted in the ceiling. [Brief explanation of the drawings]

[0021] An embodiment of the present invention will be described below with reference to the accompanying drawings. As shown in Figures 1 and 2, a support 1 of this embodiment is fastened to a horizontally disposed square bar 3 (such as a joist) with a rectangular cross section, which is a ceiling component placed above the ceiling, and supports the underside edge of a ceiling-mounted device (support object) such as a ventilation fan 2 to be installed above the ceiling.

[0022] The support 1 is a bent metal member having a pair of opposing surface portions 11, 12 facing the side portions of the square bar-shaped material 3, a connecting surface portion 13 connecting the pair of opposing surface portions 11, 12 on the upper surface portion of the square bar-shaped material 3, and a protruding piece portion 14 extending from the lower end side of one of the opposing surface portions 11 located on the installation side of the ventilation fan 2 to the fixing point side on the underside of the ventilation fan 2.

[0023] In addition, two circular fastening insertion holes 11a, 13a are formed on one of the opposing surface portions 11 and the connecting surface portion 13 located on the installation side of the ventilation fan 2, through which fastening members 4 such as screws for fastening the support device 1 to the square bar-shaped material 3 are passed.

[0024] Furthermore, the protruding piece 14 is formed with a fixing insertion hole 14a through which a fixing member 5 such as a screw is passed to fix the ventilation fan 2 to the support 1. The fixing insertion hole 14a is an elongated hole that is elongated in the extension direction of the square bar-shaped material 3.

[0025] In the mounting structure for the ventilation fan 2 using the support 1, the ventilation fan 2 is placed between two parallel-arranged square rods 3. On one side of the ventilation fan 2, one support 1 is placed on each of the two square rods 3, and is fastened by fastening members 4 passed through the fastening insertion holes 11a in the opposing surface 11 of the support 1, as shown in FIG. 3(A). On the other side of the ventilation fan 2, one support 1 is placed on each of the two square rods 3, and is fastened by fastening members 4 passed through the fastening insertion holes 13a in the connecting surface 13, as shown in FIG. 3(B). The ventilation fan 2 is supported by the protruding pieces 14 of the four support members 1, and is fixed by fixing members 5 passed through the fixing insertion holes 14a.

[0026] In installing the ventilation fan 2 using the support 1, before the ceiling material is installed, the installer fastens one support 1 to each of two parallel-arranged square bar-shaped materials 3 with fastening members 4 passed through fastening insertion holes 11a in the opposing surface portions 11, as shown in Figure 3(A). Meanwhile, as shown in Figure 4, the installer temporarily places one support 1 on each of the two square bar-shaped materials 3.

[0027] The installer causes the protruding pieces 14 of the two supports 1 fastened as described above to support one side of the lifted ventilation fan 2. Then, a different installer, or this can be the same installer, slides the two temporarily placed supports 1 toward the other side of the ventilation fan 2, and causes the protruding pieces 14 of these two supports 1 to support the other side of the ventilation fan 2.

[0028] Next, the installer fastens the four supports 1, which support one side and the other side of the ventilation fan 2, to the square bar 3 with fastening members 4 passed through the fastening insertion holes 13a of the connecting surface portion 13. Then, the installer fixes the ventilation fan 2 to the supports 1 with fixing members 5 passed from below through the fixing insertion holes 14a of the protruding piece portions 14 of the four supports 1.

[0029] With the support 1 configured as described above, the U-shaped portion formed by the pair of opposing surfaces 11, 12 and the connecting surface 13 can be used to hook onto the square bar 3 and adjust its position by sliding, which prevents the support 1 from hitting the ventilation fan 2 when attaching it, allowing for smooth installation work. Furthermore, since the connecting surface 13 is positioned on the upper surface of the square bar 3, the horizontal position of the protruding piece 14 is automatically determined.

[0030] Furthermore, according to the mounting structure for the ventilation fan 2 using the support 1, the ventilation fan 2 can be supported by the two square rod-shaped materials 3 using four support devices 1. When fastening the support devices 1 to the square rod-shaped materials 3 using the fastening members 4, the fastening operation is facilitated by using the fastening insertion holes 11a in the facing surface portions 11 of two of the four support devices 1. While it is generally difficult to insert a screwdriver vertically above the square rod-shaped materials 3 to fasten the fastening members 4, it is easy to fasten the fastening members 4 into the fastening insertion holes 11a by holding the screwdriver horizontally, which facilitates fastening the support devices 1 to the square rod-shaped materials 3. Furthermore, since the fastening insertion holes 13a in the connecting surface portions 13 are used for the other two support devices 1, the fastening members 4 can be passed through the fastening insertion holes 13a in the connecting surface portions 13 of the other two support devices 1, even if the facing surface portions 11 of the other two support devices 1 are blocked by the ventilation fan 2.

[0031] Furthermore, according to the method of installing the ventilation fan 2 using the support 1, one side of the ventilation fan 2 is supported by the protruding pieces 14 of the two support devices 1, and then the two temporarily placed support devices 1 are slid toward the other side of the ventilation fan 2, and the other side of the ventilation fan 2 is supported by the protruding pieces 14 of these two support devices 1, thereby preventing the ventilation fan 2 from hitting the support device 1 when installing the ventilation fan 2 and allowing the installation work to be carried out smoothly.

[0032] The support 1 is not limited to a configuration having fastening insertion holes 11a in the opposing surface portion 11 and fastening insertion holes 13a in the connecting surface portion 13. For example, as shown in Figures 5(A) and 5(B), the support 1 may have only fastening insertion holes 13a in the connecting surface portion 13, and the fastening insertion holes 13a in the connecting surface portion 13 may be used for the first two of the four support devices 1 to be fastened, and the fastening insertion holes 13a in the connecting surface portion 13 may also be used for the last two to be fastened.

[0033] Alternatively, as shown in Figures 6(A) and 6(B), the support 1 has fastening insertion holes 13a in the connecting surface portion 13 and fastening insertion holes 12a in the opposing surface portion 12, and the fastening insertion holes 13a in the connecting surface portion 13 can be used for the first two of the four support devices 1 to be fastened, and the fastening insertion holes 12a in the opposing surface portion 12 can be used for the last two to be fastened.

[0034] The fastening insertion holes in the support 1 are not limited to the above-described embodiments, and it is sufficient that fastening insertion holes through which fastening members for fastening the support 1 to the square bar-shaped material 3 are passed are formed in at least one surface of the pair of opposing surface portions 11, 12 and the connecting surface portion 13. Also, various types of support 1 having fastening insertion holes formed in different locations may be used. In the mounting structure and construction method for the ventilation fan 2, the support 1 may be fastened to the square bar-shaped material 3 by a fastening member 4 passed through any of the fastening insertion holes, and the ventilation fan 2 may be supported by a total of four protruding pieces 14 of the support 1.

[0035] Although the embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited to the illustrated embodiments. Various modifications and variations can be made to the illustrated embodiments within the same scope as the present invention or within an equivalent scope. [Explanation of symbols]
