Embodiment.
1. 1. Configuration of Embodiment FIG. 1 is a perspective view of a state in which a space securing component according to an embodiment of the present disclosure is installed in a ceiling installation, viewed from the floor side. FIG. 2 is a plan view of the state in which the space securing component according to the embodiment of the present disclosure is installed in the ceiling equipment, viewed from the ceiling side. Moreover, FIG. 3 is a front view of a state in which the space securing component according to the embodiment of the present disclosure is installed in the ceiling equipment, viewed from the front side. In these figures, the air conditioner 10 is a ceiling facility installed in the space above the ceiling. Typically, the air conditioner 10 is suspended from the superstructure 8 of the building frame by suspension bolts 12 . These figures illustrate the state during the construction period of the ceiling equipment. Peripheral facilities such as a ceiling base, ducts, wiring, and piping have not yet been installed around the air conditioner 10 . Also, the ceiling has not yet been installed.

A duct 14 is connected to the side of the air conditioner 10 . In the drawing, only the connecting portion of the duct 14 is illustrated for clarity. The air conditioner 10 has a maintenance opening/closing cover 16 on its side surface. The maintenance opening/closing cover 16 is configured as a side-opening door. FIG. 2 shows an inspection opening 6 that is installed after laying the ceiling. A worker who performs inspection enters the ceiling space through the inspection opening 6 and accesses the air conditioner 10 . Maintenance inspection parts of the air conditioner 10 are accommodated inside the maintenance opening/closing cover 16 . Typically, the air conditioner 10 has a filter 4 as a maintenance and inspection component. In FIG. 2 , two plate-shaped vertical filters 4 are accommodated inside the air conditioner 10 . The filter 4 can be removed by pulling it forward from the opened opening of the opening/closing cover 16 for maintenance.

Here, when opening the opening/closing cover 16 for maintenance and when pulling out the filter 4, a space for work is required in front of the opening/closing cover 16 for maintenance. The space required for this work is hereinafter referred to as "maintenance space". When peripheral facilities such as pipes or ducts are installed through the maintenance space, it is impossible to enter the space above the ceiling through the inspection opening 6, the opening/closing cover 16 for maintenance cannot be opened, and the filter 4 cannot be pulled out. Failure to do so may result in malfunction.

Therefore, the maintenance space securing method of the present embodiment prevents peripheral equipment from being installed in the maintenance space by installing the space securing component 20 in the maintenance space during the construction period of the ceiling equipment. FIG. 4 is a diagram for explaining the configuration of the space securing component. The space securing component 20 includes a wire frame 22 , a mesh member 24 and a fixing member 26 .

The wire frame 22 constitutes the skeleton of the outer shape of the space securing component 20 . Typically, the wire frames 22 are configured so that the four wire frames 22 bent into a rectangular shape with rounded corners are movably combined in the longitudinal direction to form a box-shaped outline that is close to a rectangular parallelepiped as a whole. be done. Further, the lengthwise dimension of the wire frame 22 is configured to be longer than the depth dimension of the filter 4 in the pull-out direction. In addition, the dimension of the wire frame 22 in the lateral direction is configured to be longer than the width dimension perpendicular to the drawing direction of the filter 4 .

The mesh member 24 is stretched on the surface having the outer shape of each of the four wire frames 22 . The mesh member 24 is colored, for example, yellow for easy identification. Moreover, the material of the mesh member 24 is desirably a lightweight and well-ventilated mesh structure. Alternatively, the mesh member 24 may be stretched over the bottom surface or the top surface formed by the sides of the four wire frames 22 in the short direction.

The fixing member 26 is a member configured to protrude from the lateral side of the wire frame 22 forming the upper surface of the space securing component 20 when the space securing component 20 is horizontally arranged in the longitudinal direction. . In FIG. 4 , two upper belt members are provided as fixing members 26 . The number of belt members as the fixing member 26 is not limited. The space securing component 20 is fixed to the air conditioner 10 by inserting the fixing member 26 into the gap of the maintenance opening/closing cover 16 .

Next, a specific fixing method for the space securing component 20 will be described. FIG. 5 is a diagram showing an example of a method of attaching the space securing component. 5 is an enlarged view of the space securing component attached to the air conditioner 10 as viewed from the front of the air conditioner 10. As shown in FIG. The space securing component 20 is installed during the construction of the peripheral equipment of the air conditioner 10 . In the installation process of the space securing component 20, as shown in this figure, one or a plurality of upper belt members as fixing members 26 are pulled from the upper side of the maintenance opening/closing cover 16 while the maintenance opening/closing cover 16 is slightly opened. It hangs down toward the back side. By completely closing the opening/closing cover 16 for maintenance, the fixing member 26 is sandwiched and fixed.

During construction of the peripheral equipment, the space securing component 20 functions to make the surroundings recognize the maintenance space of the air conditioner 10 as an installation prohibited area for the peripheral equipment. By avoiding the space securing component 20 when constructing the peripheral equipment, the contractor of the peripheral equipment can prevent erroneously installing the peripheral equipment in the maintenance space of the air conditioner 10 .

When the construction of the peripheral equipment is completed, the space securing component 20 is removed. Here, the clamped fixing member 26 is released by the operation of opening the open/close cover 16 for maintenance. This allows the space securing component 20 to be easily removed.

According to the configuration and fixing method of the space securing component 20, the following actions and effects are obtained.

The fixing member 26 can be attached and detached by opening and closing the maintenance open/close cover 16 without using any tools or the like. In particular, since the place where the air conditioner 10 is installed is high, the operator needs to use a stepladder or the like. In addition, since the ceiling may be installed when the space securing component 20 is removed, the space behind the ceiling may be narrow and dark. For this reason, the configuration in which the space securing component 20 can be attached and detached with simple work greatly contributes to the reduction of the burden on the operator.

The space securing component 20 is composed of a wire frame 22 and a mesh member 24. According to such a configuration, the shape of the space securing component 20 can be maintained while being lightweight. This makes it possible to sufficiently hold the space securing component 20 simply by sandwiching the fixing member 26 between the opening/closing cover 16 for maintenance.

The mesh member 24 contributes to making the space securing component 20 easily recognizable from the surroundings. In particular, by coloring the mesh member 24 in a conspicuous color such as yellow, the degree of identification can be further enhanced. In addition, since the mesh material allows air to pass through, it is possible to reduce the possibility that the space securing component 20 will come off due to being blown by the wind.

The space securing component 20 has longer dimensions in the longitudinal direction and the transverse direction than the dimensions in the depth direction and the width direction of the filter 4, respectively. According to such a space securing component 20, the space securing component 20 secures a range in which the filter 4 can be pulled out reliably.

4. Modifications The maintenance space securing method using the space securing component 20 of the present embodiment may be modified as follows.

4-1. Space securing component 20
The space securing component 20 may be configured to be flatly foldable. FIG. 6 is a diagram showing an example of the space securing component in a folded state. The space securing component 20 shown in this figure can be folded so that the four wire frames 22 overlap each other by pushing the longitudinal sides of the rectangular parallelepiped in the diagonal direction of the short side direction. According to such a configuration, the space securing component 20 can be easily carried to the installation location. Further, if the space securing component 20 is folded after being removed from the air conditioner 10, it becomes easier to take out the space securing component 20 from the narrow inspection opening 6.例文帳に追加

The space securing component 20 can adopt various shapes other than a box shape as long as the shape can occupy the maintenance space.

A lower belt member is provided. Each of the fixing members 26b has a connecting portion 261 for connecting the upper and lower fixing members 26b to each other at the tip. Typically, the coupling portion 261 is exemplified by a hook-and-loop fastener, a button, a hook, and the like.

In the space securing component 20 of the second modified example, the connecting portions 261 of the upper and lower fixing members 26b are joined together on the back side of the maintenance opening/closing cover 16 with the maintenance opening/closing cover 16 opened. Then, by completely closing the opening/closing cover 16 for maintenance, the fixing member 26 is sandwiched and fixed at the upper and lower sides. According to such a fixing method, even if the maintenance opening/closing cover 16 should be opened, the space securing component 20 can be prevented from falling off.

Further, in the space securing component 20 of the second modified example, the fixing member 26b does not have to have a special configuration as the coupling portion 261. In this case, the space securing component 20 of the second modified example may be connected by tying the connecting portions 261 of the upper and lower fixing members 26b.
