Description

The present disclosure relates to a rain curing structure for a building interior unit provided inside a building frame.

In recent years, when constructing buildings used for hotels, apartment complexes, etc., the building is divided into multiple units (building units) and manufactured in advance at a factory, and these building units are assembled at the construction site to shorten the construction period. A unit construction method that can shorten the construction period is being implemented. As a building unit used in such a construction method, there is a known building unit that has columns made of steel pipes, floor beams and ceiling beams made of H-beam steel, and the peripheries of the floor beams and ceiling beams are covered in advance with fireproof coating material. There is (Patent Document 1).

In this building unit, a floor slab made of ALC is laid on the floor beams, and a toilet, bathroom, system kitchen, air conditioner, door, etc. are arranged inside the building unit. Furthermore, wall panels that serve as the partition walls and external wall panels that serve as the exterior walls on the hallway and balcony sides are fixed between the pillars. In addition, the upper surface of the ceiling beam of the lower-floor unit located on the lower floor and the lower surface of the floor beam of the upper-floor unit located on the upper floor are separated from each other, which reduces piping space and piping space. It is increasing.

Patent No. 4553649

By the way, the building unit described in Patent Document 1 does not have a roof. Therefore, until the upper floor unit is placed above, the top surface (or the back surface of the ceiling board if the ceiling board is fixed) is exposed. Additionally, the back side of the wall board that forms the boundary wall is also exposed on the side of the building unit. When these interior boards are exposed to rain, they absorb water and emit lye, so they need to be replaced. Therefore, building units with exposed interior materials need to be protected from rain to prevent them from getting wet.

When rain curing a building unit as described in Patent Document 1, since the building unit has a rectangular parallelepiped shape and is sturdy, for example, a control panel is laid on the top surface to make the top surface of the unit flat, and then the top surface of the unit is flattened. It is possible to cover it with a water-impermeable sheet such as a blue sheet.

On the other hand, if the unit is an interior unit installed inside a building frame, it is not necessary to make the unit as sturdy as a building unit. Therefore, if someone gets on top of the interior unit to install the control panel, there is a risk that the interior unit will be damaged or deformed. However, since the top surface of the interior unit is uneven, if the sheet is placed directly over the interior unit, the water on the sheet will collect and accumulate in the area that covers the concave part of the interior unit, and there is a risk that the water will seep out of the sheet or the sheet will tear. There is a possibility.

In view of this background, the present invention provides an interior unit that can be placed and removed without a person getting on top of the interior unit, and that can prevent water from collecting in the portion covering the recess of the interior unit.

According to this configuration, it is possible to provide a downward slope to both the portion of the upper sheet that covers the first upper surface and the portion of the upper sheet that covers the second upper surface of the interior unit with one bag body. Furthermore, since only one bag is required, the rain curing structure can be easily arranged and removed.

Preferably, the upper surface of the interior unit includes a first upper surface (20a) located at one end in the longitudinal direction and a second upper surface (20a) located at the other end in the longitudinal direction and lower than the first upper surface. 21a), at least one of the bags is disposed on the first top surface, and more bags than the number of bags disposed on the first top surface are bundled so that the It is preferable to arrange it on the second upper surface.

According to this configuration, it is possible to provide a large downward slope to the portion of the upper sheet that covers the second upper surface of the interior unit, while suppressing an increase in the height of the portion of the upper sheet that covers the first upper surface.

Preferably, the interior unit further includes a water-impermeable side sheet (31) provided in the interior unit so as to cover a side surface of the interior unit.

According to this configuration, the part of the upper sheet that covers the upper part of the side surface of the interior unit is provided to the position where it overlaps with the side sheet, so that the side surface of the interior unit is covered. height) can be reduced. Therefore, the arrangement and removal of the upper sheet becomes easy.

In this embodiment, there is a space between the interior units 12 adjacent to each other in the column direction. However, a soundproofing member may be provided between the interior units 12 adjacent to each other in the column direction. Further, an RC wall may be provided between the interior units 12 adjacent to each other in the row direction with the internal pillar 3B in between.

FIG. 2 is a perspective view of the main parts of the building 1 under construction. As shown in FIG. 2, each pair of outer peripheral columns 3A adjacent to each other in the column direction are connected to each other by a first beam 4A extending in the column direction. Each pair of internal columns 3B adjacent to each other in the column direction are also connected to each other by a first beam 4A extending in the column direction. Each pair of outer peripheral columns 3A and internal columns 3B that are adjacent to each other in the inter-beam direction is connected to each other by a second beam 4B that extends in the inter-beam direction. Each pair of internal columns 3B (only one of which is shown in FIG. 2) adjacent to each other in the inter-beam direction are also connected to each other by second beams 4B extending in the inter-beam direction.

In this embodiment, the outer circumferential column 3A is configured by vertically connecting a plurality of outer circumferential column members 16A made of PCa concrete and having substantially the same length as the height of one floor. The internal column 3B is constructed by vertically connecting a plurality of internal column members 16B made of PCa concrete and having a length substantially the same as the height of one floor. Here, "substantially the same" means to include a degree of difference by the thickness of the joint.

The first beam 4A connecting each pair of outer circumferential columns 3A is constituted by a first outer circumferential beam member 17A made of PCa concrete and having substantially the same length as the interval between the outer circumferential columns 3A. A gate-shaped outer circumferential frame portion 18 is configured on the outer circumferential portion of the frame 2 by a pair of outer circumferential column members 16A adjacent to each other and a first outer circumferential beam member 17A that connects them. The first beam 4A connecting each pair of internal columns 3B is constituted by a first internal beam member 17B made of PCa concrete and having substantially the same length as the interval between the internal columns 3B.

The second beam 4B that connects the outer peripheral column 3A and the inner column 3B is constituted by a second outer beam member 19A made of PCa concrete and having substantially the same length as the interval between the outer peripheral column 3A and the inner column 3B. The second beam 4B connecting the internal columns 3B is constituted by a second inner beam member 19B made of PCa concrete and having substantially the same length as the interval between the internal columns 3B.

In other embodiments, both the outer peripheral column 3A and the internal column 3B may be composed of one column member and a joint member made of PCa concrete. Further, the first beam 4A and the second beam 4B may be constituted by one beam member and the beam portions of two joint members provided on both sides of the beam member. Furthermore, the first beam members 17 (17A, 17B) may be composed of only beam portions of two joint members.

These PCa concrete members are manufactured in advance at a factory, transported by trailer to a construction site, and assembled at the construction site. The PCa concrete members are connected to each other by joining reinforcing bars (not shown) protruding from one member to mechanical joints (not shown) provided on the other member. Another PCa concrete member having a reinforcing bar insertion hole may be placed between the two PCa concrete members. The connection of PCa concrete members is not limited to this construction method, and may be performed by other known construction methods.

As mentioned above, the width of the interior unit 12 is limited for transportation purposes. On the other hand, by disposing a plurality of interior units 12 between each pair of outer circumferential column members 16A adjacent to each other in the row direction, the interval between the outer circumferential column members 16A is not limited by the size of the interior units 12. It is possible to make it larger. Thereby, the frame 2 can be made into a rational structure that allows easy transportation and assembly of PCa concrete members.

FIG. 3 is a perspective view of the interior unit 12 of the building 1. As shown in FIGS. 2 and 3, the interior unit 12 has a substantially rectangular parallelepiped shape, and in order to increase the ceiling height of the room 6 and enlarge the space, a part of the interior unit 12 is formed on the lower surface of the first beam 4A and A bulging portion 20 is provided that bulges upward from the lower surface of the second beam 4B. In this embodiment, one bulging portion 20 is provided in a room portion on the other end side opposite to the entrance door 15 of the interior unit 12.

The bulging portion 20 is located at a position away from the first beam 4A and the second beam 4B, that is, between a pair of first beam members 17 adjacent to each other in the inter-beam direction and between a pair of second beam members 17 adjacent to each other in the column direction. It is located between the beam members 19 (more specifically, the second outer beam members 19A). Beam shapes projecting into the room portion of the chamber 6 are formed on two sides (the upper part of the one end portion 12a and the one side portion 12b) corresponding to the first beam 4A and the second beam 4B of the bulging portion 20.

Note that no beam shape is formed in a portion of the interior unit 12 on the entrance door 15 side where the bulging portion 20 is not provided (hereinafter referred to as the general portion 21). The bulging portion 20 forms an upper surface higher than the upper surface of the general portion 21. In other words, the upper surface of the interior unit 12 includes the first upper surface 20a of the bulging portion 20 located at one end in the longitudinal direction, and the general portion 21 located at the other end in the longitudinal direction and lower than the first upper surface 20a. and a second upper surface 21a.

By providing the interior unit 12 with the bulging portion 20 in this manner, the chamber 6 is expanded upward, and the generation of dead space above the chamber 6 is suppressed. Further, since the bulging portion 20 is surrounded by the pair of first beam members 17 and the pair of second beam members 19, the interior unit 12 does not shift significantly in the horizontal direction.

The interior unit 12 includes a pedestal 22 disposed at the lower end, a three-dimensional frame 23 assembled on the pedestal 22, and an interior board etc. disposed inside the frame 23 and assembled to the frame 23. It has an interior material 24. The frame 22 is made of a steel material having higher rigidity than the frame 23, such as H-shaped steel, I-shaped steel, or a channel. By attaching a jig to a support portion formed on the frame 22, the interior unit 12 can be lifted by a lifting machine. The frame body 23 is made of a steel material that is less rigid and lighter than the frame 22, such as a square pipe 25 or LGS 26 (Light Gage Steel). Each rectangular surface of the frame body 23 has at least four sides made up of square pipes 25, and when the interval between the square pipes 25 becomes a predetermined value or more, at least one square pipe is formed so that the interval becomes a predetermined value or less. LGS26 is arranged. An opening 27 is formed on the side surface of one end 12 a of the interior unit 12 at a position that aligns with the window opening 8 in the outer wall 9 .

In addition, in FIG. 3, only the LGS 26 arranged on one surface is shown, and the LGS 26 arranged on the other surface is omitted. The LGS 26 is provided not only on the side surface of the frame body 23 but also on the top surface. The LGS 26 and the interior material 24 may not be provided in the portion where the unit bath 14 is provided. An inspection port 28 that can be opened and closed by an inspection door is formed on the top surface of the unit bath 14. Electrical wiring and water pipes (not shown) are placed on the top surface of the interior unit 12. A sewage pipe (not shown) is accommodated in the lower part of the interior unit 12 , specifically, in the internal space of the pedestal 22 .

Building 1 is configured as described above. In this way, since the frame 2 of the building 1 is made of RC construction, the seismic performance of the building 1 can be easily ensured.

On the other hand, the interior unit 12 is not configured as a structural member of the building 1, and has lower rigidity than a structural member. Furthermore, the back surface of an interior material 24 such as an interior board is exposed on the outer surface of the interior unit 12. Therefore, it is necessary to protect the interior unit 12 from rain so that it does not get wet. Therefore, the rain protection structure 30 is provided on the interior unit 12 after it is manufactured in a factory. The rain curing structure 30 will be explained in detail below.

FIG. 4 is a perspective view showing the rain protection structure 30 of the interior unit 12 during installation. As shown in FIG. 4, the interior unit 12 is provided with a side sheet 31 so as to cover the side surface of the interior unit 12. The side sheet 31 may be made of any material as long as it is non-water permeable, and there are no limitations on the material. It's fine. The side sheet 31 is attached to the interior unit 12 by bonding at least the upper portion to the frame 23.

The side sheet 31 may be composed of a single sheet developed to cover the entire circumference of the side surface, or may be composed of a plurality of sheets divided in the circumferential direction and arranged so as to overlap in the circumferential direction. may be configured. Further, the side sheet 31 may be a curing film in which a resin film and an adhesive tape are pasted together in advance. The side sheet 31 is attached to the interior unit 12 with adhesive tape so that the upper edge is located at or near the upper edge of the side surface of the interior unit 12 (the side surface of the part other than the part where the beam shape is provided). . The side sheet 31 preferably has a height such that its lower edge is lower than the upper edge of the pedestal 22 . On the other hand, the upper edge of the side sheet 31 does not have to reach the upper edge of the side surface of the interior unit 12.

FIG. 5 is a perspective view showing the rain protection structure 30 of the interior unit 12. As shown in FIG. 5, the interior unit 12 is provided with an upper sheet 32 so as to cover the upper surface of the interior unit 12. The upper sheet 32 is placed over the interior unit 12 so as to cover the entire upper surface of the interior unit 12 and at least the upper part of the side surface of the interior unit 12. The portion of the upper sheet 32 that covers the side surface of the interior unit 12 has a height that overlaps at least the upper portion of the side sheet 31.

The upper sheet 32 may be any material as long as it is impermeable to water from the outside to the inside, and preferably allows water vapor to permeate from the inside to the outside. Further, the upper sheet 32 preferably has flexibility and rigidity to the extent that it has shape retention properties. The material of the upper sheet 32 is not limited, but may be, for example, a composite sheet of polyethylene resin and polyester nonwoven fabric. As such a sheet, for example, Super Airtex (registered trademark) manufactured by Fukubi Chemical Industry Co., Ltd. can be used.

A bag 33 is provided between the upper surface of the interior unit 12 and the upper sheet 32. The bag 33 may be made of, for example, polyvinyl chloride and may be airtight. The bag body 33 includes a bag body 34 and an inlet/exhaust port 35 for injecting and discharging gas into the bag body 34. The bag main body 34 may have any shape, but by being placed between the upper surface of the interior unit 12 and the upper sheet 32, the bag body 34 forms a ridge on the upper sheet 32 and extends toward the periphery of the interior unit 12. to provide a downward water gradient. The water gradient may be one-sided or two-sided.

Since the rain protection structure 30 includes the upper sheet 32 and the bag body 33 in this manner, the rain protection structure 30 can be placed and removed without a person getting on the interior unit 12. Furthermore, since the bag 33 provides the upper sheet 32 with a downward slope toward the peripheral edge of the interior unit 12, water is prevented from collecting in the portion of the upper sheet 32 that covers the recessed portion of the interior unit 12.

In this embodiment, the bag main body 34 has an elongated substantially cylindrical shape in an inflated state, and is disposed approximately at the center of the interior unit 12 in the lateral direction along the longitudinal direction of the interior unit 12. As a result, the distance from the portion of the upper sheet 32 that is raised by the bag body 33 to the periphery of the interior unit 12 becomes smaller at all positions, and a larger water gradient is applied to the upper sheet 32 than when the bag body 34 is spherical. has been done.

Further, the bag body 34 has a length slightly smaller than the longitudinal dimension of the interior unit 12, and has a general portion lower than the first upper surface 20a of the bulging portion 20 of the interior unit 12 and the first upper surface 20a. 21 and the second upper surface 21a. As a result, one bag body 34 provides a downward slope to both the portion of the upper sheet 32 that covers the first upper surface 20a of the interior unit 12 and the portion of the upper sheet 32 that covers the second upper surface 21a. Since only one bag body 33 is required in this way, the arrangement and removal of the rain curing structure 30 is facilitated.

The inlet/outlet portion 35 functions as a valve for allowing gas to be injected/discharged to/from the bag body 34 . Preferably, the inlet/outlet portion 35 has a tubular shape extending from the bag body 34, and gas can be injected/discharged at the tip of the tube. Since the bag body 33 includes the bag body 34 and the injection/discharge port 35, the bag body 34 can be inflated or contracted by injecting and discharging gas from the injection/discharge port 35. Thereby, it is possible to provide the upper sheet 32 with an appropriate downward slope. Further, when drainage of rainwater is not necessary, the height of the rain curing structure 30 can be reduced by shrinking the bag body 34. Therefore, when the interior unit 12 is mounted on the vehicle, it is possible to reduce the height of the vehicle equipped with the interior unit 12.

The upper sheet 32 is processed into a three-dimensional shape that matches the shape of the bag body 34 when it is inflated. Specifically, the upper sheet 32 is manufactured to have a three-dimensional shape by joining a plurality of sheets cut to an appropriate size to each other by stitching, adhesion, welding, or the like. Since the upper sheet 32 is flexible, it can be folded when not in use. The upper sheet 32 has the above-mentioned three-dimensional shape in the unfolded state, and is attached to the interior unit 12 by being placed over the interior unit 12. The upper sheet 32 may be fixed to the interior unit 12 with a fixing member such as a clip, a rope, or a hook.

In other embodiments, the lower edge of the portion of the upper sheet 32 that covers the side surface of the interior unit 12 reaches a position lower than the upper edge of the pedestal 22, and the upper sheet 32 may cover substantially the entire side surface of the interior unit 12. good. In this case, the side sheet 31 can be omitted.

On the other hand, the rain protection structure 30 of this embodiment includes the side sheet 31, so that the portion of the upper sheet 32 that covers the upper part of the side surface of the interior unit 12 is provided to a position where it overlaps the side sheet 31. The side surfaces of the interior unit 12 are covered. Therefore, the size of the top sheet 32 (height of the portion covering the side surfaces) can be reduced, which facilitates placement and removal of the top sheet 32.

FIG. 6 is a sectional view showing the rain protection structure 30 of the interior unit 12. As shown in FIGS. 5 and 6(A), the inlet/outlet part 35 is arranged to pass through the inspection port 28 of the interior unit 12, and the tip of the inlet/outlet part 35 is arranged inside the interior unit 12. . By arranging the inlet/outlet portion 35 inside the interior unit 12 in this manner, the work of injecting and discharging gas to/from the bag body 34 can be performed inside the interior unit 12 . Furthermore, when removing the rain curing structure 30, the bag body 33 can be recovered inside the interior unit 12 by pulling the inlet/outlet part 35 from inside the interior unit 12 after shrinking the bag body 34.

FIG. 6(B) is a sectional view showing a rain curing structure 30 according to a modified example. In this example, the upper sheet 32 has a double structure including an upper upper sheet 32U and a lower upper sheet 32L, and the bag body 33 is housed between the upper upper sheet 32U and the lower upper sheet 32L. There is. Even in this case, the inlet/outlet portion 35 of the bag body 33 is preferably disposed such that its tip is located inside the interior unit 12 through the slit or hole formed in the lower upper sheet 32L.

By storing the bag body 33 between the upper upper sheet 32U and the lower upper sheet 32L in this way, the bag body 33 can be placed and removed at the same time as the upper sheet 32, and the rain curing structure 30 can be arranged. and removal becomes easier.

FIG. 6(C) is a sectional view showing a rain curing structure 30 according to a further modification. In this example, the bag body 34 of the bag body 33 has a shape in which cylindrical portions of different sizes are connected in the width direction. It is preferable that the internal spaces of the cylindrical parts adjacent to each other communicate with each other. With such a configuration, the bag body 33 is provided with one injection/discharge port 35, and the bag main body 34 can be inflated or contracted by injecting and discharging gas through the injection/discharge port 35. . Further, it is possible to provide the upper sheet 32 with an appropriate slope.

FIG. 7 is a perspective view showing a rain curing structure 30 according to another embodiment, and FIG. 8 is a sectional view thereof, specifically, FIG. 8(A) is a sectional view taken along line VIIIA in FIG. FIG. 8(B) is a sectional view taken along line VIIIB in FIG. As shown in FIGS. 7 and 8, in this embodiment, the structure of the bag body 33 is different from the above embodiment. This will be explained in detail below. In addition, the same code|symbol is attached|subjected to the same or similar structure as the said embodiment, and the overlapping description is abbreviate|omitted.

In this embodiment, the rain protection structure 30 includes a plurality of bags 33. Each bag 33 has a substantially cylindrical shape having the same cross-sectional size smaller than those of the above embodiments. Each bag 33 may have the same length or different lengths. In the illustrated example, a bag unit 37 made up of three bags 33 bound together by a binding member 36 is disposed on the first upper surface 20a of the bulging portion 20 of the interior unit 12. A bag unit 37 formed by bundling ten bags 33 with a binding member 36 is arranged on the second upper surface 21a of the general section 21 of the interior unit 12. The top of the bag unit 37 placed on the first top surface 20a and the top of the bag unit 37 placed on the second top surface 21a are approximately at the same height.

In this way, in this embodiment, there are more bags than the number of bags 33 arranged on the second upper surface 21a of the general part 21 than on the first upper surface 20a of the bulged part 20, which is higher than this. 33 are arranged in a bundle. As a result, the portion of the upper sheet 32 that covers the second upper surface 21a of the interior unit 12 is given a large downward slope, and the height of the portion of the upper sheet 32 that covers the first upper surface 20a is suppressed from increasing. Note that it is sufficient that at least one bag 33 is provided on the first upper surface 20a, and the bag unit 37 does not need to be provided.

Although the description of the specific embodiments has been completed above, the present invention is not limited to the above-mentioned embodiments and can be widely modified and implemented. In addition, the specific configuration, arrangement, quantity, materials, arrangement and removal procedures of each member and portion can be changed as appropriate without departing from the spirit of the present invention. On the other hand, all of the constituent elements shown in the above embodiments are not necessarily essential and can be selected as appropriate.
