Description

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

In recent years, when constructing a building used for a hotel or an apartment house, the building is divided into multiple units (building units) and manufactured in advance at the factory, and these building units are assembled at the construction site. A unit construction method that can shorten the cost is being implemented. As a building unit used in such a construction method, a building unit having a pillar made of steel pipe, a floor beam made of H-shaped steel, and a ceiling beam, and the circumference of the floor beam and the ceiling beam is pre-coated with a fireproof coating material is known. There is (Patent Document 1).

In this building unit, a floor slab made of ALC is laid on the floor beams, and a toilet, a bathroom, a system kitchen, an air conditioner, a door, etc. are arranged inside the building unit. Further, between the pillars, a wall panel that serves as a door boundary wall, an outer wall panel that forms an outer wall on the corridor side and the balcony side, and the like are fixed. In addition, since the upper surface of the ceiling beam of the lower floor unit arranged on the lower floor and the lower surface of the floor beam of the upper floor unit arranged on the upper floor are separated from each other, the piping space and the piping space are increased accordingly. It is increasing.

Japanese Patent No. 4553649

By the way, the building unit described in Patent Document 1 does not have a roof. Therefore, the upper surface (or the back surface of the ceiling board when the ceiling board is fixed) is exposed until the upper floor unit is arranged above. In addition, the back side of the wall board, which is the doorway wall, is also exposed on the side surface of the building unit. These interior boards contain water and produce lye when hit by rain and need to be replaced. Therefore, the building unit whose interior material is exposed needs to be rain-cured so that it will not get wet by being hit by rain.

When a building unit as described in Patent Document 1 is rain-cured, the building unit has a rectangular parallelepiped shape and is sturdy. Therefore, for example, a control panel is laid on the upper surface to flatten the upper surface of the unit, and the upper surface of the unit is flattened. It is conceivable to cover with a non-permeable sheet such as a blue sheet.

On the other hand, when the unit is an interior unit provided inside the skeleton, it is not necessary to make the unit as sturdy as a building unit. Therefore, if a person gets on the interior unit to lay the control panel, the interior unit may be damaged or deformed. However, since the upper surface of the interior unit has irregularities, if the sheet is placed directly on the interior unit, water on the sheet collects and accumulates in the portion covering the recess of the interior unit, and there is a risk that water may seep out from the sheet or the sheet may be torn. There is a risk.

In view of such a background, the present invention is for an interior unit which can be arranged and removed without a person riding on the interior unit and can prevent water from collecting in a portion covering the recess of the interior unit. The challenge is to provide a rain-curing structure for the water.

In order to solve such a problem, an embodiment of the present invention is a rain curing structure (30) for an interior unit (12) of a building (1) provided inside a skeleton (2).

It is preferable that the bag body is arranged so as to straddle the first upper surface and the second upper surface, including 21a).

According to this configuration, it is possible to impart a downward gradient to both the portion of the upper sheet covering the first upper surface of the interior unit and the portion of the upper sheet covering the second upper surface by one bag body. Moreover, since only one bag is required, it is easy to arrange and remove the rain curing structure.

Preferably, the upper surface of the interior unit is a first upper surface (20a) located on one end side in the longitudinal direction and a second upper surface (20a) located on the other end side in the longitudinal direction and lower than the first upper surface. 21a) and at least one bag body is arranged on the first upper surface, and the bag bodies are bundled in a larger number than the number of the bag bodies arranged on the first upper surface. It may be placed on the second upper surface.

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

Preferably, a non-permeable side sheet (31) provided in the interior unit so as to cover the side surface of the interior unit may be further provided.

According to this configuration, the side surface of the interior unit is covered by providing the portion of the upper sheet that covers the upper part of the side surface of the interior unit up to the position where it overlaps the side sheet, so that the size of the upper sheet (the portion that covers the side surface) Height) can be reduced. Therefore, the arrangement and removal of the upper sheet becomes easy.

Preferably, the upper sheet has a double structure, and the bag body is housed between the upper upper sheet and the lower upper sheet.

According to this configuration, the bag body can be arranged and removed at the same time as the upper sheet, and the rain curing structure can be easily arranged and removed.

As described above, according to the present invention, rain for an interior unit can be arranged and removed without a person riding on the interior unit, and water can be suppressed from collecting in a portion covering the recess of the interior unit. A curing structure can be provided.

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

In the present embodiment, the outer peripheral column 3A is configured by vertically connecting a plurality of outer peripheral column members 16A made of PCa concrete having substantially the same length as the height of one layer. The inner pillar 3B is configured by vertically connecting a plurality of inner pillar members 16B made of PCa concrete having substantially the same length as the height of one layer. Here, substantially the same means that the degree of difference is included by the thickness of the joint.

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

The second beam 4B connecting the outer peripheral column 3A and the inner column 3B is composed of a second outer beam member 19A made of PCa concrete having substantially the same length as the distance between the outer peripheral column 3A and the inner column 3B. The second beam 4B connecting the inner columns 3B to each other is composed of a second inner beam member 19B made of PCa concrete having substantially the same length as the interval between the inner columns 3B.

In another embodiment, the outer column 3A and the inner column 3B may both be composed of one column member made of PCa concrete and a joint member. Further, the first beam 4A and the second beam 4B may be composed of one beam member and beam portions of two joint members provided on both sides thereof. Further, the first beam member 17 (17A, 17B) may be composed of only the beam portions of the two joint members.

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

As mentioned above, the width of the interior unit 12 is limited for transportation. On the other hand, by arranging a plurality of interior units 12 between each pair of outer peripheral column members 16A arranged adjacent to each other in the girder direction, the interval between the outer peripheral column members 16A is not limited by the size of the interior unit 12. It can be made larger. As a result, the skeleton 2 can be made into a rational structure in which the PCa concrete member can be easily transported and assembled.

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 increase the space, a part of the lower surface of the first beam 4A and the lower surface of the first beam 4A and the space are increased. A bulging portion 20 that bulges above the lower surface of the second beam 4B is provided. In the present embodiment, one bulging portion 20 is provided in the 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 avoiding 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 beam-to-beam direction and a pair of second members adjacent to each other in the girder direction. It is located between the beam members 19 (more specifically, the second outer beam member 19A). A beam shape protruding into the chamber portion of the chamber 6 is formed on the two sides (the upper portion 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.

A beam shape is not formed on the 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 is the first upper surface 20a of the bulging portion 20 located on one end side in the longitudinal direction and the general portion 21 located on the other end side in the longitudinal direction and lower than the first upper surface 20a. It includes a second upper surface 21a.

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

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

Note that FIG. 3 shows only the LGS26 arranged on one surface, and the LGS26 arranged on the other surface is not shown. The LGS 26 is provided not only on the side surface of the frame body 23 but also on the upper surface 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 upper surface of the unit bath 14. The electrical wiring and the water supply pipe (not shown) are placed on the upper surface of the interior unit 12. A sewage pipe (not shown) (not shown) is housed in the lower part of the interior unit 12, specifically, the internal space of the gantry 22.

Building 1 is configured as described above. Since the skeleton 2 of the building 1 is made of RC in this way, 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 a lower rigidity than the structural member. Further, the back surface of the interior material 24 such as the interior board is exposed on the outer surface of the interior unit 12. Therefore, the interior unit 12 needs to be rain-cured so as not to be hit by rain and get wet. Therefore, the interior unit 12 is provided with the rain curing structure 30 after being manufactured at the factory. Hereinafter, the rain curing structure 30 will be described in detail.

FIG. 4 is a perspective view showing the rain curing structure 30 of the interior unit 12 being installed. 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 a non-permeable material and is not limited in material, but is, for example, a resin film containing a thermoplastic resin such as a polyamide resin or a polyolefin resin as a main component. It's okay. The side sheet 31 is attached to the interior unit 12 by adhering at least the upper portion to the frame body 23.

The side sheet 31 may be composed of one sheet developed so as to cover the entire circumference of the side surface, and a plurality of sheets divided in the circumferential direction are arranged so as to overlap in the circumferential direction. It may be configured. Further, the side sheet 31 may be a curing film in which a resin film and an adhesive tape are integrally attached in advance. The side sheet 31 is attached to the interior unit 12 with an adhesive tape so that the upper edge is located on the upper edge or the vicinity of the upper edge of the side surface of the interior unit 12 (the side surface of the portion other than the portion provided with the beam shape). .. The side seat 31 may have a height at which the lower edge reaches a position lower than the upper edge of the gantry 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 curing 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 covers the entire upper surface of the interior unit 12 and covers at least the upper surface 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 part of the side sheet 31.

The upper sheet 32 may have non-permeability from the outside to the inside, and preferably allows the permeation of water vapor from the inside to the outside. Further, the upper sheet 32 is preferably rigid enough to have flexibility and shape retention (shape retention). The material of the upper sheet 32 is not limited, but may be, for example, a composite sheet of a polyethylene resin and a polyester non-woven 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 formed of, for example, polyvinyl chloride and has airtightness. The bag body 33 includes a bag body 34 and an injection / discharge port 35 for injecting / discharging gas into / from the bag body 34. The bag body 34 may have any shape, but by being arranged between the upper surface of the interior unit 12 and the upper sheet 32, a ridge is formed on the upper sheet 32 and directed toward the peripheral edge of the interior unit 12. Gives a downward water gradient. The water gradient may be one-sided or two-sided.

By providing the rain curing structure 30 with the upper sheet 32 and the bag body 33 in this way, the rain curing structure 30 can be arranged and removed without a person riding on the interior unit 12. Further, since the bag body 33 provides the upper sheet 32 with a downward slope toward the peripheral edge of the interior unit 12, it is possible to prevent water from collecting in the portion of the upper sheet 32 that covers the recess of the interior unit 12.

In the present embodiment, the bag main body 34 has a long substantially cylindrical shape in an inflated state, and is arranged along the longitudinal direction of the interior unit 12 at substantially the center in the lateral direction of the interior unit 12. As a result, the distance from the portion of the upper sheet 32 raised by the bag body 33 to the peripheral edge of the interior unit 12 becomes smaller at all positions, and a large water gradient is given to the upper sheet 32 as compared with the case where the bag body 34 is spherical. Has been done.

Further, the bag body 34 has a length slightly smaller than the dimension in the longitudinal direction of the interior unit 12, and is a first upper surface 20a of the bulging portion 20 of the interior unit 12 and a general portion lower than the first upper surface 20a. It is arranged so as to straddle the second upper surface 21a of 21. As a result, the one bag main body 34 imparts a downward gradient 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 33 is required in this way, the rain curing structure 30 can be easily arranged and removed.

The injection / discharge port 35 functions as a valve for enabling the injection / discharge of gas to / from the bag body 34. It is preferable that the injection / discharge port 35 has a tubular shape extending from the bag body 34, and gas can be injected / discharged at the tip of the tube. When 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 the injection / discharge of gas from the injection / discharge port 35. This makes it possible to impart an appropriate downward slope to the upper sheet 32. Further, when the drainage of rainwater is not required, the height dimension 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, the height of the vehicle on which the interior unit 12 is mounted can be lowered.

The upper sheet 32 is processed into a three-dimensional shape that matches the shape when the bag body 34 is inflated. Specifically, the upper sheet 32 is manufactured so as 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 covering the interior unit 12 from above. The upper sheet 32 may be fixed to the interior unit 12 by a fixing member such as a clip, a rope, or a hook.

In another embodiment, even if 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 gantry 22, and the upper sheet 32 covers 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 curing structure 30 of the present embodiment includes the side sheet 31, whereby the portion of the upper sheet 32 covering the upper part of the side surface of the interior unit 12 is provided up to a position where it overlaps with the side sheet 31. The side surface of the interior unit 12 is covered. Therefore, the size of the upper sheet 32 (height of the portion covering the side surface) can be reduced, which facilitates the arrangement and removal of the upper sheet 32.

FIG. 6 is a cross-sectional view showing the rain curing structure 30 of the interior unit 12. As shown in FIGS. 5 and 6 (A), the pouring / discharging port 35 is arranged so as to pass through the inspection port 28 of the interior unit 12, and the tip of the pouring / discharging port 35 is arranged inside the interior unit 12. .. By arranging the injection / discharge port 35 inside the interior unit 12 in this way, the gas injection / discharge operation for the bag body 34 can be performed inside the interior unit 12. Further, when the rain curing structure 30 is removed, the bag body 33 can be collected inside the interior unit 12 by pulling the injection / discharge port 35 from the inside of the interior unit 12 after shrinking the bag body 34.

FIG. 6B is a cross-sectional view showing the rain curing structure 30 according to the modified example.
