Description

Technical Field

[0001] The present invention relates to an attachment structure for fixing a facility device to a metal frame fixed to an opening on the front surface of a pipe shaft in a multi-family house via a metal attachment fitting.

Background Art

[0002] When installing a facility device such as a water heater in a pipe shaft of a multi-family house, an attachment fitting is fixed to the facility device, and this attachment fitting is attached together with the facility device to a 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, in the case of 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 into 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] Patent Document 1 discloses a technique for facilitating the attachment and detachment of a storage-type electric water heater unit by installing the storage-type electric water heater unit on a pedestal made of a rectangular parallelepiped-shaped steel frame with a ramen structure and providing a plurality of casters at the lower end of the pedestal.

[0005] Patent Document 2 discloses a technique for easily inserting and removing an electric water heater into and out of a cabinet by providing T-shaped slide means near the bottom of both sides of the electric water heater and providing a pair of guide means having a U-shaped cross section on the bottom plate of the cabinet, and guiding the slide means by the guide means.

[0007] As described above, when installing the equipment into the frame at the opening of the pipe shaft, it was necessary to support the equipment from the space in front of the pipe shaft and push it inwards to insert it, without workers being able to enter the pipe shaft itself. This required a great deal of effort to install the equipment. The technologies described in Patent Documents 1 and 2 are difficult to adopt when fixing equipment to a metal frame installed in the opening of a pipe shaft.

[0008] The objective of the present invention is to provide an equipment mounting structure that simplifies the installation work of equipment on a pipe shaft. [Means for solving the problem]

[0009] The mounting structure for the equipment according to claim 1 is a structure for fixing the equipment to a metal frame fixed to an opening in the front of a pipe shaft via mounting fittings, wherein the side of the case of the equipment is provided with rail members that slope upward from front to rear, and the metal frame has at least one rectangular frame-shaped mounting opening for mounting the equipment with a plurality of vertical members and a plurality of horizontal members connecting these vertical members, and the left and right vertical members of the mounting opening are provided with a pair of guide parts for guiding the rail members.

[0010] According to the above configuration, the metal frame has at least one mounting opening for attaching the equipment, and the left and right vertical members of the mounting opening are provided with guide parts that guide rail members provided on the side of the equipment case. As the equipment and mounting bracket are pushed into the opening while guiding the pair of rail members on the left and right with the pair of guide parts, the equipment moves upward towards the back of the opening and reaches a predetermined mounting state.

[0011] The mounting structure for the equipment according to claim 2 is characterized in that, in the invention of claim 1, the guide portion is a rectangular notch provided on the inner side of the left and right vertical members of the mounting opening. According to the above configuration, the guide portion is a rectangular notch provided on the inner side of the vertical member, resulting in a simple guide structure that can be implemented at low cost.

[0012] The mounting structure for the equipment according to claim 3 is characterized in that, in the invention of claim 2, the lower edge of the rectangular notch is bent toward the inside of the pipe shaft in accordance with the upward slope. According to the above configuration, the lower edge of the rectangular notch is bent toward the inside of the pipe shaft in accordance with the upward slope, thereby ensuring the guiding performance of the guide section.

[0013] The mounting structure for the equipment according to claim 4 is characterized in that, in the invention of claim 1, the guide portion is an idler wheel capable of supporting the rail member. According to the above configuration, since the guide portion is an idler wheel capable of supporting the rail member, the frictional resistance when the guide portion guides the rail member is reduced, and the work efficiency when installing the equipment can be increased. [Effects of the Invention]

[0014] As described above, the present invention provides various effects and benefits. [Brief explanation of the drawing]

MODE FOR CARRYING OUT THE INVENTION

[0016] Hereinafter, embodiments for carrying out the present invention will be described based on examples.

[0017] The mounting structure of the equipment device according to the embodiment will be described based on FIGS. 1 to 6. FIGS. 1 to 3 show the steps of installing an equipment device 3 and a mounting bracket 4 attached thereto on a metal frame 2 fixed to the opening of a pipe shaft 1 in a condominium. Details of this installation procedure will be described later.

[0018] As shown in FIGS. 1 to 3, a metal frame 2 is fixed to the front opening of the pipe shaft 1. This metal frame 2 has left and right vertical members 5, 6, a pair of horizontal members 7, 8 connecting the upper and lower ends of these vertical members 5, 6, a middle partition horizontal member 9, and a partition vertical member 10 at approximately the center in the left - right direction, and a rectangular frame 2A fixed to the front opening of the pipe shaft 1 and rectangular frame - shaped mounting openings 2B, 2C formed in the upper half of this rectangular frame 2A are formed.

[0019] The equipment device 3 installed in the mounting opening 2B is rectangular in shape, and a rectangular frame-shaped mounting bracket 4 is fixed to its front end in an external fitting manner. As shown in Figures 4 to 6, rail members 12 are fixed to the left and right side surfaces 3a of the equipment device 3, respectively, and are inclined upward from front to rear. These rail members 12 are formed from a strip with a hat-shaped cross-section, and the hat-shaped protrusions are provided to project laterally. .

[0020] As shown in Figure 1, when the lower end of the equipment device 3 is aligned with the lower end of the mounting opening 2B when the equipment device 3 is installed in the mounting opening 2B, the height dimension A of the space formed near the upper end of the mounting opening 2B is set to be equal to the upward inclination distance S of the rail member 12 shown in Figure 5.

[0021] As shown in Figure 4, a pair of guide portions 13 are formed on the inner side of the pair of left and right vertical members 10, 6 that form the mounting opening 2B, to guide a pair of rail members 12 on the side surface 3a of the equipment device 3. The guide portions 13 consist of rectangular notches that open toward the mounting opening 2B side. The height dimension B of the guide section 12 from the horizontal member 9 is set to be equal to the height dimension B from the lowest end of the equipment device 3 at the rear end of the rail member 12 shown in Figure 5.

[0022] Next, the procedure for assembling the equipment device 3 with the mounting bracket 4 attached into the mounting opening 2B will be explained based on Figures 1 to 3 and Figure 6. First, as shown in Figure 1, the rear end of the equipment device 3 with the mounting bracket 4 is slightly inserted into the mounting opening 2B, and as shown in Figure 6, the rear ends of the pair of rail members 12 are slightly inserted into the pair of guide parts 13.

[0023] Next, as shown in Figure 2, the equipment device 3 with the mounting bracket 4 is pushed and inserted into the mounting opening 2B while maintaining a horizontal position. At this time, the pair of rail members 12 are guided by the pair of guide parts 13 as the equipment device 3 is inserted while rising due to the upward slope of the rail members 12, and is attached to the mounting opening 2B. As a result, a predetermined gap is created at the lower end of the mounting opening 2B, but when the front door 3f is attached to the equipment device 3 at the end, it will be in the state shown in Figure 3, and the installation of the equipment device 3 will be completed.

[0024] As described above, by forming a pair of guide sections 13 on the vertical members 6 and 10 of the mounting opening 2B and providing rail members 12 on each of the pair of case sides 3a of the equipment device 3, the workload when installing the equipment device 3 can be reduced and work efficiency can be increased.

[0025] Next, the mounting structure of the equipment related to the modified configuration will be explained based on Figure 7. As a replacement for the aforementioned guide section 13, a pair of idler wheels 13A are provided at a height corresponding to the guide section 13, on a pair of vertical members 6 and 10, capable of supporting a pair of rail members 12. These idler wheels 13A are configured to protrude inward from the inner edges of the vertical members 6 and 10 to support the rail members 12, and the idler wheels 13A are attached to support brackets that extend rearward from the vertical members 6 and 10.

[0026] This guide section, consisting of the idler wheel 13A, significantly reduces the frictional resistance acting between the rail member 12 and the equipment device 3 during assembly. This greatly reduces the workload when installing the equipment device 3 and significantly increases work efficiency. Those skilled in the art can make various modifications to the mounting structure of the equipment according to the above embodiment, in addition to those described in the embodiment.
