Description

Technical Field

[0001] The present invention relates to a storage structure for pipes and wirings provided in a dwelling of an apartment house, for example.

Background Art

[0002] Conventionally, storage structures for pipes and wirings related to lifelines such as electricity, gas, and water supply provided in a living room of a building have been treated as important elements for determining the structure and appearance of the building or living room, the exclusive areas between adjacent living rooms, the floor plan of the living room, and other building specifications. In particular, since the pipes and wirings related to electricity are diverse depending on the number, type, and arrangement of electrical equipment provided in the living room, these storage structures have been continuously studied for many years.

[0003] For example, Patent Document 1 discloses a pipe storage structure for an air conditioner. Specifically, a pipe cover is provided from the indoor side in a groove-shaped recess formed in the height direction of the inner wall, and the pipe of the air conditioner is inserted through a hole for inserting a pipe formed in the pipe cover to be concealed. According to this configuration, the pipe is not exposed to both the indoor side and the outdoor side, and the pipe cover is detachable, so that maintenance and replacement of the pipe can be easily performed.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the pipe cover in Patent Document 1 has an overlapping section that extends to cover the gap (end) that occurs around the periphery of the recess. In other words, the surface of the pipe cover including the overlapping section becomes a step with respect to the inner wall, which may impair the aesthetic appeal. Furthermore, in order to avoid the occurrence of the above step, the pipe cover must be made into a complex shape or the gypsum board or base material must be recessed to accommodate the step, which may increase the cost of materials and construction.

[0006] Furthermore, the structure in which the pipe cover is detachable is not significantly different from the structure of an inspection opening formed in a typical inner wall, so it cannot be said that it facilitates pipe maintenance or replacement. In other words, since maintenance and replacement of existing pipes installed using the concealed (pre-installed) piping system can be done through the inspection opening, there is little reason to prioritize the advantages of Patent Document 1 over the disadvantages of the concealed piping system.

[0007] Furthermore, in typical living spaces, including those described in Patent Document 1, a common structure is one in which through-holes for air conditioner sleeves are formed in the exterior wall next to window openings, from the standpoint of ease of construction. However, in the above structure, the area of ​​the opening may be reduced because priority is given to the through-holes. In other words, in order to increase the area of ​​the opening, the through-holes should be formed in positions other than those adjacent to the opening in the lateral direction, including next to the opening.

[0008] Furthermore, some living spaces have meter boxes for electricity, gas, and water meters located adjacent to window or door openings formed in the exterior wall, and some of these meter boxes are designed to conceal a portion of the exterior wall. In other words, if the initial construction plan includes the installation of this type of meter box, forming the through-hole in the location hidden by the meter box makes it easier to widen or flexibly set the area of ​​the opening.

[0009] However, the risks of forming through-holes in the exterior wall should also be considered. In other words, from the standpoint of the performance that exterior walls should possess, such as seismic resistance, durability, and fire resistance, it is difficult to easily form through-holes in the exterior wall. Therefore, the inventors concluded that the aforementioned problem regarding the area of ​​the opening can be solved by adopting an exterior wall structure and construction plan that does not impair the above performance even if through-holes are formed in advance.

[0010] Therefore, the object of the present invention is to provide a piping and wiring storage structure that does not impair the performance that the exterior wall should have and makes it easy to form an opening of a desired area in the exterior wall. [Means for solving the problem]

[0011] In other words, the present invention relates to a piping and wiring storage structure for a living room in a building, wherein the living room comprises an exterior wall, a meter box covering a part of the exterior wall, and air conditioning piping and wiring provided across the interior and exterior sides of the exterior wall, the exterior wall having an opening for a door located outside the meter box, and a fitting member provided in a through groove located inside the meter box, the fitting member having a plurality of first through holes leading into the meter box, and the air conditioning piping and wiring being inserted into the meter box through the first through holes.

[0012] With this configuration, since the air conditioning piping and wiring, which employ a concealed piping system, are housed outside the exterior wall and inside the meter box via the first through-hole of the fitting member, the through-hole for the air conditioning sleeve is not formed in a position adjacent to the door opening, including next to it, which is expected to make it easier to secure the area of ​​the opening. Furthermore, since the position of the fitting member and the meter box can be easily determined at the construction planning stage, it becomes easier to flexibly determine the specifications, including the area of ​​the door opening.

[0013] The following describes the definitions and examples of the technical elements that constitute the piping and wiring storage structure in the present invention.

[0014] "Buildings" include, for example, apartment buildings, detached houses, temporary housing, schools, hospitals, facilities for the elderly, facilities for people with disabilities, and various commercial facilities, and are not limited in terms of structure or size, such as reinforced concrete, steel-reinforced concrete, steel frame, wall-type structures, or rigid frame structures. In the case of apartment buildings with multiple living rooms, a structure in which the "living rooms" and "exterior walls" in this invention are located along an open corridor or other outdoor location is preferred, but the specifications of the floor plan, size, and construction method are not limited.

[0015] "Exterior walls" can refer to structural members (framework) of a building, such as seismic walls, columns, and beams made of concrete with cement as the main component, or non-structural members, including those with the same structure as structural members but with larger openings such as entrances and exits. They can be precast or not, and in the case of non-structural members, they can be made of materials other than concrete, such as ALC (Autoclaved Light Weight concrete) or EPC (Extruded Cement Panel).

[0016] The "exterior wall" may consist of a single structural member, a single non-structural member, or a composite of adjacent structural and non-structural members. The shape of the "exterior wall" may be planar, L-shaped, or U-shaped, and in the case of apartment buildings, it may form an alcove.

[0017] The "meter box" may be of a type in which a case with an openable door is formed to protrude outward from the exterior wall (hereinafter also referred to as "Type 1"), or of a type in which an openable door is attached to a recess or cavity formed in a part of the exterior wall (hereinafter also referred to as "Type 2"), and there are no limitations on the shape, size, or other specifications.

[0018] "Joinery" refers to, for example, metal or wooden sashes, glass windows and doors, or combinations thereof. Windows can be sliding, bay windows, or fixed, and doors can be sliding or hinged. There are no limitations on their shape, size, or other specifications.

[0019] An "opening" may be formed by the formwork used when pouring the exterior wall, or by cutting the exterior wall; it may be rectangular or circular; it may be the size of a window or a door; and it is located adjacent to the meter box at a predetermined distance.

[0020] "Air conditioning piping and wiring" refers to piping installed in the room before the air conditioner is installed, as part of a concealed piping system. "Air conditioning piping" refers to a refrigerant pipe alone, a drain pipe alone, or both the refrigerant pipe and the drain pipe, while "air conditioning wiring" refers to power lines. The diameter of the "air conditioning piping" or "air conditioning piping and wiring" should be smaller than the diameter of the first penetration hole, and should not interfere with insertion through the first penetration hole. The "air conditioner" can be any known indoor or outdoor unit, as long as it is compatible with the concealed piping system, and its shape, size, and function are not limited.

[0021] A "penetrating groove" is a vertically elongated groove with a width of 100 mm to 200 mm, which may be formed by the formwork during the casting of the exterior wall, or by cutting the exterior wall, may be a gap between structural members and non-structural members forming the exterior wall, or may be used for installing seismic isolation slits. The "penetrating groove" may be located between the exterior wall as a double-wall structure and the interior wall made of laminated gypsum board or the like, which is located on the living room side of the exterior wall.

[0022] The "fitting member" is a shape that can be fitted into the through groove, and is made of concrete with cement as the main component, ALC, or EPC, and may or may not be formed by the precast method, and is fixed to the exterior wall by known means such as screws, angle materials, or adhesives. Two or more "first through holes" are formed in the vertical direction of the fitting member at predetermined or irregular intervals, and each is 40φ to 80φ, with 55φ to 65φ being appropriate from the viewpoint of workability and fire resistance.

[0023] The following describes a more desirable configuration for the piping and wiring storage structure in the present invention.

[0024] The meter box in the present invention has a second through hole connecting the inside and the outside of the meter box, and it is desirable that the air conditioner piping is inserted from the inside of the meter box to the outside through the second through hole.

[0025] The "second through hole" is located near the lower end of the meter box and is formed on the side plate when the meter box is of the first type and on the outer wall when the meter box is of the second type.

[0026] According to this configuration, since the air conditioner piping can be connected to the outdoor unit adjacent to the meter box through the second through hole, the construction labor can be saved as it is not necessary to lay it on the outer wall with a pipe cover, and the design property of the appearance can also be expected.

[0027] The living room in the present invention further includes piping and wiring for the living room such as electricity, gas, and water supply, and it is desirable that the piping and wiring for the living room are inserted from the inside of the room into the meter box through the first through hole.

[0028] According to this configuration, since the first through hole can be utilized as a path for connecting the piping and wiring for the living room to each meter in the meter box, the construction efficiency can be improved and the performance degradation of the outer wall can be avoided as it is not necessary to separately form other through holes on the outer wall.

[0029] Further, the present invention is a construction method of the above-described piping and wiring storage structure, and includes a step of causing the air conditioner piping and wiring, and the piping and wiring for the living room to crawl from the indoor side to near the fitting member, and a step of inserting the air conditioner piping and wiring, and the piping and wiring for the living room into the meter box from the first through hole.

[0030] ]According to these steps, based on the construction plan, the piping and wiring for the air conditioner, as well as the piping and wiring for the living room, are first gathered near the fitting components. Then, based on the constraints of at least one or more of the following, such as the route, outer diameter (thickness), the relative positions of each meter, and the structure of the meter box, each is inserted into the meter box through the first through-hole according to the optimal order and height. This prevents the piping and wiring from interfering with each other, and is expected to facilitate future maintenance and replacement. [Effects of the Invention]

[0031] According to the present invention, it is possible to expect the effect of easily forming an opening of a desired area in an exterior wall without impairing the performance that the exterior wall should possess. [Brief explanation of the drawing]

[0032] [Figure 1] This diagram shows (a) a schematic view from the interior of a living room looking towards the open corridor side, and (b) a schematic view from the open corridor side looking towards the interior of a living room employing a piping and wiring storage structure according to one embodiment of the present invention. [Figure 2] The above diagram shows a schematic view (a) of a living room with the above-described piping and wiring storage structure, looking from the open corridor side towards the interior, and a cross-sectional view of the XX portion of (a). [Modes for carrying out the invention]

[0033] The piping and wiring storage structure (hereinafter also referred to as "this piping and wiring storage structure") in one embodiment of the present invention will be described below with reference to Figures 1 and 2. In these figures, in cases where there are multiple identical parts, only one part is numbered. For the sake of explanation, some designated parts and their connecting lines are shown as hidden lines (dashed lines). In the explanation, terms indicating directions such as up, down, vertical, horizontal, and perpendicular are basically based on ordinary buildings, and when other standards are used, they will be explained as appropriate.

[0034] <Overview of the main piping and wiring storage structure> This piping and wiring storage structure is used in the living rooms of a reinforced concrete apartment building. The apartment building has multiple floors, and each floor has an open corridor (not shown). As shown in Figure 1, the living room comprises an entrance / exit (not shown) located on the open corridor side, the room R, an exterior wall 1 that forms part of the room R, a meter box 2 that covers part of the exterior wall 1 from the open corridor side, and an air conditioner 3 for the room R. The exterior wall 1 has a window opening 11 on the parapet wall located outside the meter box 2, and a fitting member 13 provided in a through groove 12 located inside the meter box 2. The air conditioner 3 comprises an indoor unit 3a installed near the opening 11, an outdoor unit 3b installed near the meter box 2, and at least a refrigerant pipe / drain pipe 3c and a power line 3d connected to the indoor unit 3a. The fitting member 13 has multiple first through holes 13a that lead to the inside of the meter box 2. The air conditioning pipes 3c and wiring 3d are inserted into the inside of the meter box 2 through the first through-hole 13a.

[0035] <Details of Exterior Wall 1> As shown in Figure 2, the exterior wall 1 is composed of an ALC panel 1a, a column 1b adjacent to the ALC panel 1a, and a beam 1c located above the ALC panel 1a. The surface of the ALC panel 1a facing the open corridor and the surface of the column 1b are adjacent and flush. The beam 1c protrudes from the ALC panel 1a towards the open corridor. The opening 11 is formed in the ALC panel 1a. The through groove 12 corresponds to the gap between the ALC panel 1a and the column 1b, and is formed in a vertically elongated shape from the floor slab F corresponding to the open corridor to the lower end surface of the beam 1c. The embedded member 13 is an ALC block formed by the precast method.

[0036] <Details of Meter Box 2> As shown in Figure 2, the meter box 2 has an openable door 2a and a side portion 2b that is approximately perpendicular to the door 2a, and is installed to cover the ALC panel 1a, which is part of the exterior wall 1, and the column 1b. In other words, the side portion 2b is installed so as to be approximately perpendicular to the ALC panel 1a, and the through hole 12 and the fitting member 13 are installed to be housed inside. The meter box 2 may be formed in the shape of a hollow case with the door 2a, the side portion 2b, and a top surface (not shown). The distance W between the side portion 2b and the end of the opening 11 adjacent to it is 400 mm to 600 mm. The side portion 2b has a second through hole 21 that connects the inside and outside of the meter box 2.

[0037] <Details of Air Conditioner 3> As shown in Figure 2, the indoor unit 3a is located above the opening 11 and installed on the interior wall B. The interior wall B may or may not be a decorative beam. The outdoor unit 3b is placed on the floor slab F of the open corridor so as to be side-by-side with the meter box 2. The refrigerant pipes, drain pipes 3c and power lines 3d are routed from an unnumbered air conditioner sleeve formed in the interior wall B to the back of the interior wall B (or under the floor or in the ceiling space, not shown), hanging down toward the fitting member 13, and inserted into the inside of the meter box 2 through the first through-hole 13a.

[0038] The refrigerant pipes / drain pipes 3c and power lines 3d may include refrigerant pipes / drain pipes laid on the back side of the inner wall B as a concealed piping system. Due to diameter constraints, the refrigerant pipes / drain pipes 3c and power lines 3d may be inserted into the first through-hole 13a in groups, such as a single refrigerant pipe, a drain pipe, and a power line, or a single drain pipe, a refrigerant pipe, and a power line. The refrigerant pipes / drain pipes 3c are open to the outside of the meter box 2 via the second through-hole 21 of the meter box 2, the refrigerant pipes may be connected to the outdoor unit, and the drain pipes may be connected to a drain rail (not shown) laid on the floor slab F of the open corridor.

[0039] <Details of piping and wiring for living spaces 4> As shown in Figure 1, the living room is further equipped with piping and wiring 4 for the living room, such as electricity, gas, and water, which are connected to various parts of the room, including room R. The piping and wiring 4 for the living room are routed under the floor, in the ceiling space, and behind the interior wall B to the fitting member 13, and are inserted into the inside of the meter box 2 through the first penetration holes 13a, excluding the locations where the refrigerant pipes, drain pipes 3c and power lines 3d are inserted.

[0040] <Expected effects of this piping and wiring storage structure> As shown in Figure 2, since the refrigerant pipes, drain pipes 3c and power lines 3d, which employ a concealed piping system, are housed outside the living space and inside the meter box 2 via the first through-hole 13a of the fitting member 13, the through-hole for the air conditioner sleeve is not formed in a position adjacent to the window opening 11 on the low wall, including the side of the opening 11. This makes it easier to secure the area of ​​the opening 11. In other words, because the positions of the fitting member 13 and the meter box 2 can be easily determined at the construction planning stage, the distance W between the side 2b of the meter box 2 and the end of the opening 11 can be secured by 100mm to 200mm compared to conventional structures, making it easier to flexibly determine the specifications, including the area of ​​the opening 11.

[0041] Furthermore, since the refrigerant pipes, drain pipes 3c, and power lines 3d housed inside the meter box 2 can be connected to the outdoor unit 3 adjacent to the meter box 2 via the second through-hole 21, it is not necessary to lay the pipes on the exterior wall with a pipe cover, thus reducing construction time and ensuring a more aesthetically pleasing appearance.

[0042] Furthermore, since the first through-hole 13a can be used as a route for connecting the piping and wiring 4 for the living spaces to each meter inside the meter box 2, it is not necessary to separately form other through-holes in the exterior wall 1, which is expected to improve construction efficiency and avoid deterioration of the exterior wall's performance.

[0043] Furthermore, when adopting this piping and wiring storage structure, the ventilation opening in room R (not shown) may be formed by penetrating the beam 1c from the interior wall B, or by penetrating the ALC panel 1a from the interior wall B so as to be located below the opening 11.

[0044] Furthermore, the piping and wiring storage structure shown in this embodiment is not limited to the above-described content, and includes the position, shape, dimensions, and relationships between any part, as long as equivalent effects can be obtained.

[0045] <Construction method and effects of this piping and wiring storage structure> The construction method for this piping and wiring storage structure assumes that at least the exterior wall 1 and meter box 2 shown in Figure 1 have already been installed. First, the refrigerant pipe / drain pipe 3c and power line 3d, as well as the piping and wiring 4 for the living room, are routed from the interior side near the fitting member 13. Then, the refrigerant pipe / drain pipe 3c and power line 3d, as well as the piping and wiring 4 for the living room, are inserted into the meter box 2 through the first penetration hole 13a.

[0046] According to these steps, based on the construction plan, the refrigerant pipes, drain pipes 3c, power lines 3d, and piping and wiring 4 for living spaces are first gathered near the fitting member 13. Then, each is inserted into the meter box through the first through-hole 13a according to the optimal order and height determined based on at least one or more constraints of their respective routes, outer diameters (thickness), the relative positions of each meter, and the structure of the meter box. This prevents the pipes and wiring from interfering with each other, and is expected to facilitate future maintenance and replacement. [Explanation of Symbols]
