Description

Technical Field

[0001] The present invention relates to a mounting bracket for fixing a facility device to a metal frame fixed to an opening of a pipe shaft in a multi-family housing.

Background Art

[0002] When installing a facility device such as a water heater in a pipe shaft of a multi-family housing, a mounting bracket is fixed to the facility device, and this mounting bracket is attached together with the facility device to the metal frame at the opening of the pipe shaft. In particular, in the case of a facility device that generates combustion exhaust or the like, it is necessary to install it at a height where the exhaust does not hit people. However, for a heavy facility device, it is quite difficult to lift the facility device during installation.

[0003] The opening of the pipe shaft is narrow, and it was necessary to install it in such a form that the facility device is inserted toward the pipe shaft side while supporting it from the front space of the pipe shaft in a state where an operator cannot enter the pipe shaft. Moreover, conventionally, since there were many cases where the installation work of the facility device was carried out manually without using a lifting device or the like, it required a great deal of labor and time.

[0004] In the mounting structure of the facility device described in Patent Documents 1 and 2, a structure is adopted in which a mounting bracket is externally fitted to the facility device, and the facility device and the mounting bracket are fixed to the metal frame at the opening of the pipe shaft.

Summary of the Invention

Problems to be Solved by the Invention

[0006] As described above, when attaching the equipment to the frame at the opening of the pipe shaft, it was necessary to install it in a manner in which workers could not enter the pipe shaft, and the equipment was supported from the space in front of the pipe shaft while being pushed and inserted into the pipe shaft. Moreover, in the past, the installation of equipment was often done manually without the use of lifting devices, which required a great deal of effort and time.

[0007] The objective of the present invention is to provide a mounting bracket for equipment that enables the use of a lifting device for the installation of equipment on a pipe shaft. [Means for solving the problem]

[0008] The invention of claim 1 is a mounting bracket for fixing equipment to a metal frame fixed to the opening of a pipe shaft, wherein the mounting bracket is composed of a frame member consisting of left and right vertical members and an upper member and a lower member connecting these vertical members, and is provided with a gap into which a claw member of a lift device can be inserted when the equipment is fixed to the mounting bracket.

[0009] According to the above configuration, the mounting bracket has a gap into which the claw member of the lifting device can be inserted when the equipment is fixed to the mounting bracket. Therefore, the mounting bracket supporting the equipment can be fixed to the frame fixed to the opening of the pipe shaft while the claw member of the lifting device is inserted into the gap and lifted. As a result, the workload can be reduced and work efficiency can be increased with a simple configuration.

[0010] The invention of claim 2 is characterized in that, in the invention of claim 1, the gap is an opening provided in the upper member or the lower member. According to the above configuration, the gap is an opening provided in the upper or lower member, and therefore the mounting bracket can be of a simple design.

[0011] The invention of claim 3 is characterized in that, in the invention of claim 1, the gap is provided between the upper member and the equipment device. According to the above configuration, since the gap is provided between the upper member and the equipment, a simple mounting bracket can be used.

[0012] The invention of claim 4 is characterized in that, in the invention of claim 1, when the equipment is fixed to the mounting bracket and placed on the floor surface, the gap is provided between the lower member and the floor surface. According to the above configuration, when the equipment is fixed to the mounting bracket and placed on the floor surface, the gap is provided between the lower member and the floor surface, which allows the maximum lift height by the lift device to be reduced, making it possible to use a smaller lift device. [Effects of the Invention]

Mode for Carrying Out the Invention

[0015] Hereinafter, embodiments for carrying out the present invention will be described based on examples.

Example

[0016] The mounting bracket of the equipment device according to Example 1 will be described based on FIGS. 1 to 7. FIGS. 1 to 4 show the stages of installing the equipment device 4 and the mounting bracket 5 attached thereto on the metal frame 3 fixed to the opening 2 of the pipe shaft 1 of the apartment house. In this case, with the equipment device 4 and the mounting bracket 5 supported by the pair of claw members 7 of the manually operated lift device 6, it is lifted to a predetermined height and then pushed backward for installation. Details of this mounting procedure will be described later.

[0017] In order to fix the equipment device 4 to the frame 3, the mounting bracket 5 shown in FIG. 5 is attached to the front end of the equipment device 4, and the equipment device 4 is fixed to the frame 3 through this mounting bracket 5. The mounting bracket 5 is composed of a frame member including left and right vertical members 8 and 9, an upper member 10 connecting these vertical members 8 and 9, and a lower member 11. In a state where the equipment device 4 is fixed to the mounting bracket 5, it has a pair of left and right gaps 12 into which the pair of left and right claw members 7 of the lift device 6 can be inserted. The pair of gaps 12 mentioned above have rectangular notches 12a as part of their structure, which are formed by cutting out portions on both sides of the central plate portion 12c in the lower part of the lower member 11.

[0018] As shown in Figures 1 to 3, the frame member 3 includes a pair of left and right vertical members 13 and 14, a horizontal upper member 15 connecting the upper ends of the vertical members 13 and 14, a horizontal lower member 16 connecting the lower ends of the vertical members 13 and 14, a horizontal middle member 15a connecting the middle section of the vertical members 13 and 14, and a partition member 17 connecting the middle member 15a and the upper member 15. Rectangular mounting openings 19 and 20 are formed in the upper half of the frame member 3 for installing the equipment device 4 and equipment equipment 18 that is slightly smaller than the equipment device 4 (see Figure 2).

[0019] When the mounting bracket 5 is attached to the front end of the equipment device 4 and the equipment device 4 and mounting bracket 5 are placed on the floor surface, a pair of gaps 12 into which the claw members 7 of the lift device 6 can be inserted are formed between the lower member 16 of the mounting bracket 5 and the floor surface via the notches 12a. When the pair of claw members 7 of the lift device 6 are inserted into the pair of gaps 12 in this state, the state shown in Figure 6 is achieved.

[0020] The lifting device 6 comprises a main body 20, a lifting body 21 mounted on the main body 20 so as to be able to move up and down, a pair of left and right claw members 7 mounted on the lifting body 21, and a lifting means (not shown) for raising and lowering the lifting body 21. The main body 20 comprises a vertical rectangular frame 22, a pair of leg members 23 extending horizontally rearward from the lower end of the rectangular frame 22, L-shaped members 24 fixed to both the left and right sides of the lower end of the rectangular frame 22 and idler wheels 25 mounted on the L-shaped members 24, and a pair of idler wheels (not shown) provided at the rear ends of the pair of leg members 23. The pair of claw members 7 consists of a pair of claw members that extend rearward from the lifting body 21 and whose left and right spacing can be adjusted.

[0021] Next, the procedure for attaching the equipment device 4, which is fixed to the mounting bracket 5, to the mounting opening 19 of the frame 3 will be explained based on Figures 1 to 4. The equipment device 4 and mounting bracket 5 are supported as shown in Figure 6 by inserting a pair of claw members 7 of the lift device 6 into a pair of gaps 12, and are moved to the front vicinity corresponding to the mounting opening 19 of the frame 3 of the pipe shaft 1 as shown in Figure 1. Next, as shown in Figure 2, the equipment device 4 and mounting bracket 5 are raised by the lift device 6 to the height of the mounting opening 19, and then, as shown in Figure 3, the equipment device 4 and mounting bracket 5 are moved backward together with the lift device 6 and pushed into the mounting opening 19 to fix the equipment device 4 and mounting bracket 5 to the frame 3.

[0022] At this time, the projection 10a at the upper end of the upper member 10 of the mounting bracket 5 is fixed to the upper member 15 of the frame 3 with screws, and the three vertical members 8 and 9 on the left and right sides of the mounting bracket 5 are fixed to the corresponding parts of the frame 3 with screws. Figure 7 shows the pair of gaps 12 into which the pair of claw members 7 were inserted, in the state in which the equipment device 4 and the mounting bracket 5 are attached to the frame 3 as described above. Next, when the front door 4f is attached to the front of the equipment device 4, the state shown in Figure 4 is achieved, and the installation work is completed.

[0023] Next, the operation and effect of the mounting bracket 5 for the equipment described above will be explained. As described above, when the equipment 4 is fixed to the mounting bracket 5, a gap 12 into which a pair of claw members 7 of the lift device 6 can be inserted is formed through the notch 12a formed in the lower member 11. Therefore, while using a mounting bracket 5 with a simple structure, it is possible to use a lift device 6 with a small maximum lift height, thereby reducing the workload of installing the equipment 4 onto the frame member 3 and increasing work efficiency. [Examples]

[0024] The mounting brackets for the equipment according to Example 2 will be explained based on Figures 8 to 13. Figures 8 to 11 show the steps involved in installing the equipment 4 on a metal frame 3 fixed to the opening 2 of the pipe shaft 1 of an apartment building, via mounting brackets 5A. In this case, the equipment device 4 and mounting bracket 5A are supported by a pair of claw members 7 of the manually operated lifting device 6, and then the device is lifted to a predetermined height and pushed backward to be installed.

[0025] Details of this installation procedure will be described later. Note that the lift device 6, the equipment device 4, and the metal frame 3 of the opening 2 of the pipe shaft 1 are the same as in Example 1. Therefore, the same reference numerals are used for parts similar to those in Example 1, and their descriptions are omitted.

[0026] To fix the equipment device 4 to the frame 3, a mounting bracket 5A is attached to the front end of the equipment device 4, and the equipment device 4 is fixed to the frame 3 via this mounting bracket 5A. As shown in Figure 12, the mounting bracket 5A is composed of a frame member consisting of left and right vertical members 8 and 9 and an upper member 10A and a lower member 11 that connect these vertical members 8 and 9.

[0027] The upper member 10A is made of a horizontal plate, and a projection 10a that protrudes upward is integrally formed in the center of the front end of the upper member 10A. A pair of rectangular tubes 27, each having a gap 26 that penetrates from front to back, into which a pair of claw members 7 of the lift device 6 can be inserted, are fixed to both the left and right sides of this projection 10a.

[0028] Next, the procedure for installing the equipment device 4, to which the above-mentioned mounting bracket 5A is attached, into the mounting opening 19 of the frame 3 will be described. With the mounting bracket 5A attached externally to the front end of the equipment device 4 (with the front door removed), as shown in Figure 8, a pair of claw members 7 of the lift device 6 are inserted into the gap 26 between the pair of rectangular tubes 27 to make it possible to lift.

[0029] Next, the lift device 6, which supports the equipment device 4 and the mounting bracket 5A, is moved to a position corresponding to the front of the mounting opening 19, and as shown in Figure 9, the lift device 6 raises the equipment device 4 and the mounting bracket 5A to the height of the mounting opening 19. Next, as shown in Figure 10, the lift device 6 supporting the equipment device 4 and mounting bracket 5A is moved to the rear, and the equipment device 4 and mounting bracket 5A are inserted into the mounting opening 19 and installed.

[0030] At this point, the projection 10a is fixed to the center of the upper member of the frame 3 with screws, and the left and right vertical members 8 and 9 are fixed to the corresponding parts of the frame 3 at three locations each with screws. Finally, the pair of claw members 7 are pulled out from the gap 26 and the front door 4f is attached, resulting in the state shown in Figure 11.

[0031] Next, the operation and effects of the mounting bracket 5A will be explained. The mounting bracket 5A has a gap 26 into which the claw members 7 of the lifting device 6 can be inserted when the equipment device 4 is fixed to the mounting bracket 5. Therefore, the mounting bracket 5A supporting the equipment device 4 can be fixed to the frame 3 fixed to one opening of the pipe shaft while the claw members 7 of the lifting device 6 are inserted into the gap 26 and lifted. As a result, the workload can be reduced and work efficiency can be increased with a simple configuration. Since the gap is formed in a rectangular tube 27, the stability when the equipment device 4 is supported by a pair of claw members 7 is increased, and the equipment device 4 is less likely to swing back and forth.

[0032] Next, we will describe an example of a modification that involves changing the mounting bracket 5A. (1) As shown in Figure 13, the upper member 10B of the mounting bracket 5B is made up of an L-shaped member consisting of a front plate 28 and a horizontal plate (not shown) that extends from the lower end of the front plate 28 to the rear. A connecting plate portion 10b with screw holes 10c is formed in the central part of the front plate 28, and a pair of gaps 29 consisting of a pair of rectangular holes into which a pair of claw members 7 of the lift device 6 can be inserted are formed on both sides of the connecting plate portion 10b of the front plate 28.

[0033] With the mounting bracket 5B fixed to the equipment device 4, a pair of claw members 7 of the lift device 6 can be inserted into a pair of gaps 29 to transport or lift the equipment device 4 and the mounting bracket 5B. Because the mounting bracket 5B forms a simple gap 29 consisting of a rectangular hole formed in the front plate 28, it can be made compactly and does not get in the way of surrounding components.

[0034] Next, we will explain various examples of changes. (1) In the example in Figure 5, a pair of rectangular tubes 27 as shown in Figure 12 may be fixed to the location of the pair of gaps 12, and the openings formed in the rectangular tubes may be used as gaps for inserting a pair of claw members 7. (2) In the example of Figure 12, the vertical members 8 and 9 may be made longer by the height of the rectangular tube 27 to form a gap between the upper member 10A and the equipment device 4, or a pair of rectangular tubes 27 may be formed on the lower side of the upper member 10A. Furthermore, those skilled in the art can implement the above-described embodiments with various modifications. [Explanation of Symbols]
