Description

[Technical Field]

[0001] The present invention relates to an air vent box used in a board ceiling in which a board such as a gypsum board is attached to a joist from below in buildings such as office buildings, hospitals, and schools, and a method for attaching the air vent box to a ceiling board using the air vent box. [Background technology]

[0002] Generally, there are two main types of ceilings used in buildings with living spaces: the traditional board ceiling, in which ceiling boards made of gypsum board or calcium silicate board are attached to the rough joists from below on the ceiling surface facing the living space, so that when viewed from below, the underlying rough joists are hidden by the boards, and the system ceiling, in which T-bars are hung from the slab above and square panels are placed on the flanges of the T-bars, and the panels can be replaced anywhere with panels equipped with lighting, air outlets, disaster prevention devices, etc., so that the T-bar flanges are visible when viewed from below. However, in living rooms where partitions are not changed frequently, board ceilings are often used due to their cost effectiveness and beautiful finish. Air conditioning ducts or ventilation ducts (hereinafter collectively referred to as air conditioning ducts) are piped in the ceiling pocket above the ceiling surface of a building, and at the end of each duct is an air vent box with the air outlet or intake (i.e., air vent) facing the inside of the room. Such air conditioning vent boxes are installed by hanging them from the ceiling pocket, i.e., above the ceiling, and are composed of a duct connection part for attaching an air conditioning duct connected to an air conditioning device or a ventilation fan, and a gas outlet through which air blown out from the air vent box is blown into the room (or air drawn into the air vent box from the room can be passed through).

[0003] In the construction of buildings such as those described above, construction companies are responsible for constructing the static structures and decorative elements related to the building's exterior and interior based on blueprints and construction drawings, while air conditioning equipment, electrical equipment, and disaster prevention equipment that operate to provide convenience to residents in rooms are respectively handled by air conditioning equipment contractors, electrical equipment contractors, and disaster prevention equipment contractors. Installation of air conditioning equipment, electrical equipment, and disaster prevention equipment is carried out by construction companies as construction work progresses and after the installation objects are completed, taking into consideration fit, work efficiency, safety, etc. For example, in ceiling construction within a building, before the ceiling substructure is installed, an air conditioning equipment contractor will hang an air conditioning vent box in the attic space between the ceiling and the floor above, and then a construction company will install the ceiling substructure's rafters and rafters, and then install the ceiling boards. If the large air vent box is not installed in the ceiling pocket before the ceiling substructure is installed, it will not fit between the rafters. After the ceiling boards are installed, the air conditioning equipment contractor marks out openings in the ceiling boards based on the ceiling plan. The construction company then follows the ceiling plan and cuts the ceiling board at the marked locations to create openings. After the opening is made in the ceiling board, the air conditioning equipment contractor brings into the site a component that will serve as an air vent that connects to the gas outlet, inserts the shutter component of the air vent from below the opening in the ceiling board, fits it into the top of the gas outlet of the air vent box that is suspended in the attic space, and then attaches a face to cover the opening in the ceiling board (Patent Document 1).

[0004] [Patent Document 1] Japanese Patent Publication No. 15028 / 1983 Summary of the Invention [Problem to be solved by the invention]

[0005] Generally, the construction of air conditioning piping such as that described above includes the installation of air vent boxes, the installation of flexible ducts, which are air conditioning ducts that are easy to connect and have come into widespread use in recent years, and the installation of air vents, but each of these installation works has a different construction period. That is, the air vent box is temporarily installed in its intended location before the ceiling substructure is constructed, and the components that will become the air vent are attached to the mounting opening of the air vent box through an opening provided in the ceiling board after the ceiling substructure construction is completed. In this way, after the air vent box is installed above the ceiling substrate, the air vent member is attached to the air outlet of the air vent box. Therefore, as part of the construction work, finishing work on the walls and floors progresses in parallel with the ceiling work, and the air vent components are delivered after the interior is finished. Therefore, if the delivery route, such as a hallway, is also undergoing finishing work, even if the installation of air vent components is possible within the room, the air vent components cannot be delivered freely, and they may have to be delivered within a limited time, with protection in place and coordination between contractors.

[0006] With regard to the installation of conventional air duct boxes, as mentioned above, there is a large time difference between the installation work of the air duct box and the installation work of the air duct itself, so it is not possible to occupy a temporary storage area on site for a long period of time, and when the air duct box is delivered before the ceiling board installation, the air duct box and the air duct components cannot be delivered at the same time; instead, the air duct box is delivered first, and the air duct components are ordered and delivered by the air duct manufacturer at an appropriate time before the ceiling base is installed. In this application, the term "air intake member" refers to a general term for rectangular products (such as air outlets, intakes, etc.) that have openings in air conditioning equipment that allow conditioned air, indoor air, etc. to circulate and are installed facing the space to be air-conditioned (for example, rectangular cash register fixtures called HS type or VHS type depending on their shape and function).

[0007] When transporting the air vent box and air vent components to the site, whether they are delivered simultaneously or separately, the air vent box and air vent components must be packed separately, which requires effort and cost for packaging. In addition to the problems of packaging and transportation costs, as mentioned above, due to differences in construction periods at the construction site, the air vent boxes and air vent components must be transported to the required floor height using a lifting lift each time, which results in poor work efficiency. In addition, if changes are omitted from the drawings due to differences in construction schedules, when the order is placed for the air vent components that fit the air vent box after checking the finished ceiling construction, many different sizes of air vent components will be delivered and piled up in a temporary storage area, which not only makes the confirmation work during the ordering process time-consuming, but also causes the problem of having to search around for them when transporting them from the temporary storage area to the site.

[0008] Furthermore, if the air vent box and air vent components are to be transported at the same time, the air vent components will need to be stored indoors until the ceiling substructure is installed and the air vent components can be installed, which is not realistic as the equipment contractor will have to move around depending on the progress of the construction work. Furthermore, the installation process for the air vent components takes a considerable amount of time from the process of hanging the air vent box, and they are delivered to the site with a time lag, so if any changes are omitted from the drawings, it can lead to problems such as the wrong size of air vent components being ordered to fit the air vent box, or the components not being installed during construction.

[0009] The present invention has been made in consideration of the above problems, and aims to provide an air duct box that, when transporting the air duct box and air duct members before construction work, can be checked against each other at a temporary storage area for handling goods at a factory or work site, and then the air duct members can be stored inside the air duct box and transported to the work site, and a method for attaching the air duct box to a ceiling board that is installed inside the ceiling by suspending the air duct box. [Means for solving the problem]

[0010] The present inventors have solved the above problems by the following means.

[0012] According to the present invention, after the ceiling board is opened, the air vent member can be attached to the air vent box at any time, which allows for more time for the installation process, making it easier for the installation contractor to adjust the schedule and reducing labor costs. In addition, there is no need to transport the air vent components before installation, which shortens the process and reduces costs. Furthermore, it can prevent problems such as delays in the process due to missed orders for air vent components, or increased costs due to incorrect sizes of air vent components. Furthermore, the air duct member is connected to the air duct box body by a spring to prevent it from falling, so it can be prevented from falling and can be carried in and worked on safely.

[0014] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 6. FIG. Figure 1 is an oblique view of an air vent box according to one embodiment of the present invention, viewed from diagonally below; Figure 2 is an oblique view showing the installation process of an air vent box according to one embodiment of the present invention; and Figure 3 is an oblique view of an air vent installed in an air vent box according to one embodiment of the present invention, viewed from below. 1 to 3, the ceiling board and ceiling substrate are not present (omitted), and in FIGS. 2 and 3, the air conditioning duct is omitted. Figure 4 is a plan view of an air vent according to one embodiment of the present invention, Figure 5 is a schematic cross-sectional view showing the air vent box attached to an opening formed in a ceiling board, and Figure 6 is an enlarged view of the area indicated by arrow X in Figure 5. In Figures 1 to 6, 1 is an air vent box, 2 is the air vent box body, 3 is a duct connection part, 4 is a gas outlet, and 5 is an air volume adjustment plate (damper) that is attached before connecting an air conditioning duct. The air intake box body 2 is made of a rectangular cylindrical hollow body, and one side of the air intake box body 2 is provided with a duct connection part 3 connected to the end of an air conditioning duct (not shown) that is connected to an air conditioner or a ventilation fan, and the bottom surface is provided with a rectangular cylindrical gas outlet 4 that blows out gas that has been sent to the box through the air conditioning duct (not shown) connected to the duct connection part 3. 4a is the lower end of the gas outlet 4. When the air intake of this air intake box 1 is an intake port, the gas flow is reversed between the gas outlet 4 and the air intake box body 2.

[0015] Within the duct connection section 3, an air volume adjustment plate (damper) 5 is provided before the air conditioning duct is connected to adjust the volume of gas (e.g., hot air or cold air) sent from the air conditioner to the air vent box main body 2. The air vent box body 2 may be a steel plate box body with insulating material such as glass wool on the inside, or an insulated box body made of glass wool board with aluminum foil attached to the surface. As shown in FIG. 1, the air diffuser box 1 is attached to the ceiling space between the ceiling board 30 (see FIG. 8) and the concrete slab 6 on the floor above by means of a fixture 7 so that the vertical height can be adjusted.

[0016] In FIG. 5, 8 is an air diffuser member, 9 is an opening frame, 10 is an insertion portion, and 11 is a flow straightening vane (horizontal direction only). The air vent member 8 shown in this embodiment consists of an opening frame body 9, a square cylindrical mounting portion 10 that stands upward from the top surface of the frame portion 9b slightly inward (about 20 mm) from the edge portion 9a of the opening frame body 9 and is inserted into the inner surface of the gas outlet 4 of the air vent box main body 2, and a lattice-shaped straightening vane 11 is provided at the opening of the mounting portion 10, but the air vent member 8 is not limited to this configuration, and the present invention can be applied to members used in air vents with similar functions. The air duct member 8 is connected to the inside of the air duct box body 2 by a spring 12 to prevent it from falling. 1 and 5, the air volume adjusting plate (damper) 5 provided in the duct connection part 3 is omitted.

[0017] 5 and 6, reference numeral 30 denotes a ceiling board, and 31 denotes an opening formed in the ceiling board 31. As shown in Figures 5 and 6, the air vent box 1 is installed in the attic space between the ceiling board 30 and the concrete slab 6 of the floor above, with its vertical height adjusted by a mounting fixture 7 so that the lower end 4a of the gas outlet 4 of the air vent box 1 is positioned slightly above the top surface of the ceiling board 30 and above the opening 31 opened in the air vent ceiling board 30. In this way, the air duct member 8 stored and kept inside the air duct box body 2 is removed from the gas outlet 4 of the air duct box 1 located above the opening 31 opened in the ceiling board 30 by removing the temporary fastening with, for example, masking tape, temporary screws or metal fittings, and the mounting part 10 provided on the air duct member 8 is inserted into the gas outlet 4 from below, and the air duct member 8 is fixed to the gas outlet 4 with an iron plate screw 20 using an electric screwdriver through an opening for an iron plate screw that has been opened in advance below the lower end of the straightening blade 11. As a result, the gas outlet 4 of the air intake box 1 is connected to the opening 31 in a communicating state. Furthermore, the gap between the ceiling board 30 and the gas outlet 4 is closed by the frame 9b from the edge 9a of the opening frame 9 of the air duct member 8 to the square cylindrical mounting part 10, preventing gas from being blown out from anywhere other than the air duct member 8, and by hiding the irregular board end of the ceiling opening 31 with the frame 9b, the design is beautiful when looking up at the ceiling. A protective member (not shown) made of synthetic resin may be provided to close the gap.

[0018] FIG. 7 is a diagram for explaining the flow of the method for attaching the air diffuser box according to the present invention, and FIG. 8 is a diagram for explaining the method for attaching the air diffuser box according to the present invention. An embodiment of a method for attaching the air duct box 1 according to the present invention to a ceiling board 30 will be described with reference to FIGS.

[0019] (Step 1) The air vent box 1 with the air vent member 8 stored inside is installed in the ceiling space between the ceiling board 30 and the concrete slab 6 on the upper floor, with the height adjusted using the fixture 7 (Figure 8(a)). (Air conditioning equipment installation) (Step 2) After the air vent box 1 is installed in the ceiling space between the concrete slab 6 on the upper floor using the fixtures 7, the ceiling base, which is the joist support, is hung from the concrete slab on the upper floor, and the joist is installed underneath to complete the base, and then the ceiling board 30 is attached to the joist and installed (Figure 8(b)). (Construction work) (Step 3) An opening 31 is marked on the ceiling board 30 at the position of the air intake box 1 attached to the ceiling space based on the ceiling plan (FIG. 8(c)). (Air conditioning equipment construction) (Step 4) The marked opening 31 is opened (FIG. 8(d)). (Construction work) (Step 5), The air vent member 8 stored in the air vent box body 2 is taken out from the opening 31 opened in the ceiling board 30 via the gas outlet 4 (FIG. 8(e)). (The following is air conditioning equipment construction.) (Step 6), The air outlet member 8 taken out from the air outlet box body 2 is attached to the gas outlet 4 and finished (FIG. 8(f)).

[0020] When the air duct box of the present invention is attached to the ceiling board 30, the air duct box 1 is attached with the air duct member 8 stored and kept inside the air duct box body 2, so there is no need to transport the air duct member 8 separately, and construction can be carried out at a time that suits the situation at the construction site. In addition, since the air duct members 8 to be attached to the air duct box 1 are stored and kept, construction work can be carried out without any trouble such as missing an order for the air duct members 8 or mistakes in delivery. In addition, since the air vent member 8 is connected in advance to the air vent box body 2 by a spring 12 for preventing it from falling during the hanging construction, the air vent is prevented from falling in the event of an earthquake even after the construction is completed, and no additional construction is required.
