Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building unit having an outdoor floor exposed outdoors and an indoor floor provided on the indoor side, wherein the outdoor floor and the indoor floor are each provided with a lightweight cellular concrete plate. And a unit building including the building unit and a balcony component arranged side by side on the outdoor side of the building unit.

[0002]

2. Description of the Related Art Conventionally, unit-type buildings formed by combining a plurality of building units manufactured in a factory at a building site have been used. The building unit is usually composed of pillars erected at the four corners, and ceiling beams and floor beams interconnecting the upper and lower ends of these pillars, and has long sides and short sides having different lengths. It has a rectangular parallelepiped frame having a rectangular planar shape. Floor materials, wall materials, and other necessary equipment members are attached to this framework in advance at a factory. According to such a unit-type building, a floor surface material or the like is attached to the building unit in advance. Therefore, there is an advantage that the construction period at the construction site can be significantly reduced.

[0003] In the case of building a unit-type building that becomes an apartment house with such building units, the floor of the building unit installed on the second floor or higher must be used as a floor.
The bottom of the building unit is covered with a thick surface material made of lightweight cellular concrete (lightweight cellular concrete plate, hereinafter referred to as ALC plate) having excellent fire resistance and sound insulation performance. The building units whose bottoms are closed are stacked on normal building units, and the floor of the building is formed by the ALC plate of the building units on the upper floor.

[0004] By the way, a balcony may be formed on the outdoor part of a building. In a unit type building, a balcony may be formed by projecting a cantilever-supported balcony on the outer wall of the building. Since the balcony unit supports only one edge, mounting work at a construction site becomes complicated. For this reason, it is conceivable to form the balcony using a so-called inner balcony unit, in which a part of the floor surface of the building unit having the floor described above is used as an outdoor floor such as a balcony. At this time, as the inner balconi unit, an intermediate beam is disposed in the outdoor and indoor compartments, and an ALC plate is provided between the intermediate beam and the floor beam parallel to the intermediate beam, that is, on the outdoor side and the indoor side, respectively. There is one that is bridged (see Japanese Patent Application Laid-Open No. 11-93272).

[0005]

In a building unit having such a floor, a support member such as a bracket for supporting both the outdoor and indoor ALC plates must be attached to the intermediate beam. However, there is a problem that the mounting structure is complicated, and therefore, the productivity of the building unit is reduced.

[0006] It is an object of the present invention to provide a building unit and a unit-type building capable of improving productivity.

[0007]

The first invention of the present invention will be described with reference to the drawings.
A ceiling beam 4 interconnecting the upper end and the lower end.
2 and a floor beam 43, and has an outdoor floor exposed to the outside and an indoor floor provided on the indoor side, and the outdoor floor and the indoor floor are provided with lightweight cellular concrete plates 51 and 52, respectively. In the building unit 40, the outdoor lightweight cellular concrete board 51 provided on the outdoor floor and the indoor lightweight cellular concrete board 52 provided on the indoor floor are arranged so that their longitudinal directions intersect with each other. The board is supported by the building unit at both longitudinal edges. According to the present invention, by arranging the outdoor lightweight cellular concrete board and the indoor lightweight cellular concrete board so that their longitudinal directions intersect with each other, the supporting points and the supporting positions of the respective lightweight cellular concrete boards are different. So, the intermediate beam only needs to be provided with a support for attaching one of the indoor and outdoor lightweight cellular concrete boards,
Thereby, the mounting structure of the lightweight cellular concrete plate is simplified, and the productivity of the building unit can be improved.

In the above, the above-mentioned ceiling beam 42 has a long side ceiling beam 42A and a short side ceiling beam 42B, and the floor beam 43 has a long side floor beam 43A and a short side floor beam 43B.
An intermediate beam 44 parallel to the long-side floor beam is disposed in the middle portion of the short-side floor beam, and the indoor lightweight cellular concrete plate is supported by being bridged between the intermediate beam and the long-side floor beam. preferable. Here, the floor (interior portion) of another general building unit installed on the second floor or higher is usually supported by a plurality of lightweight cellular concrete plates spanned between long-side floor beams. In other words, each light-weight cellular concrete board has its longitudinal direction directed to the direction between the long-side floor beams, that is, the direction along the short-side floor beam, and the short-side edge of the lightweight cellular concrete board is connected to the long-side floor beam. It is supported by being mounted on a bracket or the like attached to the. Therefore, since the supporting structure of the indoor lightweight cellular concrete plate has the same structure as the supporting structure of the lightweight cellular concrete plate in a general building unit, a mounting member such as a support is common,
Also from this point, the mounting structure of the lightweight cellular concrete plate is simplified, and the productivity of the building unit can be improved.

Further, small beams 45A and 45B are bridged between the intermediate beam and the long side floor beam on the outdoor floor side, and the outdoor lightweight cellular concrete plate is provided between the small beam and the short side floor beam or between the small beams. It is desirable that it is bridged. In this way, when the size of the outdoor part in the indoor and outdoor directions is short,
It is possible to use a long outdoor lightweight cellular concrete board along the longitudinal direction of the building unit. As a result, the number of outdoor lightweight cellular concrete plates can be reduced, and the productivity of building units can be further improved.

Further, the above-mentioned small beam and short-side floor beam include:
It is preferable that a support member that is inclined so that the upper surface becomes lower toward the outdoor side is provided, and that the outdoor lightweight cellular concrete plate be placed on the upper surfaces of the support members 55 and 56. With this configuration, it is possible to easily apply a water gradient to the upper surface of the outdoor lightweight cellular concrete plate, and it is possible to further enhance the drainage performance of the outdoor floor.

A plurality of outdoor lightweight cellular concrete boards and indoor lightweight cellular concrete boards are provided in parallel along the longitudinal direction of the building unit, and at least a central portion of each of the lightweight cellular concrete boards in the longitudinal direction of the building unit. It is desirable that a plate-like member for joining adjacent outdoor lightweight cellular concrete plates and indoor lightweight cellular concrete plates to each other is interposed between the concrete plates. Here, a flat steel (flat bar) or the like can be used as the plate-like member. By joining each lightweight cellular concrete plate with a plate-like member, the rigidity of the lightweight cellular concrete plate can be improved, and the rigidity of the outdoor floor and the indoor floor can be improved, which in turn improves the rigidity of the entire building unit. It is possible to do. In addition,
The plate-shaped member is not limited to use when joining adjacent lightweight cellular concrete boards to each other, but can be used instead of an intermediate beam that supports the angle material etc. on which the lightweight cellular concrete boards are placed. It is.

According to a second invention of the present invention, referring to the drawings, a building unit according to any one of claims 1 to 5, and a balconi component arranged side by side on the outdoor side of the building unit And a drainage channel for draining rainwater or the like that accumulates on the upper surface of the outdoor floor and the upper surface of the balcony component part at the outdoor end of the building unit. It is characterized by. According to the present invention, since the drainage channel is formed on the building unit side, the drainage channel can be manufactured in advance at a factory, and at a building site, it is only necessary to install the building unit. Good. This facilitates the construction work of the unit-type building.

According to a third aspect of the present invention, referring to the drawings, a building unit according to any one of claims 1 to 5, and a balconi component arranged side by side on the outdoor side of the building unit. In a unit-type building having: and a junction between the building unit and the balcony component,
A drainage channel 60 for draining rainwater or the like that accumulates on the upper surface of the outdoor floor and the upper surface of the balcony component portion is formed. Here, usually, the joint between the building unit and the balcony component needs to be waterproofed after joining the building unit and the balcony component so that water or the like does not leak downward from the joint. According to the present invention, since a drainage channel is also formed at a joint where a waterproofing process is required, it is possible to combine construction sites in one place, compared with a case where a new drainage channel is formed at another position. Therefore, the waterproof structure can be put together, the structure is simplified, and the construction work is also simplified, so that the work efficiency of the worker can be easily improved.

According to a fourth aspect of the present invention, referring to the drawings, a building unit according to any one of claims 1 to 5, and a balconi component arranged side by side on the outdoor side of the building unit. In the unit-type building provided with the above, a drainage channel 60C for draining rainwater or the like that accumulates on the upper surface of the outdoor floor and the upper surface of the balcony component to the outside is formed at the outdoor end of the balcony component. It is characterized by the following. According to the present invention, since the drainage channel is formed at a portion farthest from the building and at which rainwater or the like easily flows in, it is possible to easily perform the waterproofing process on the outdoor floor and the balcony component of the building unit. At the same time, it is possible to efficiently drain rainwater and the like.

Thus, the balcony of the unit building 1 is formed.
As shown in FIG. 7, a drainage channel 60 is formed at the joint between the inner balconi unit 40 and the balconi unit 70. Therefore, in rainy weather, the rainwater that falls on and collects on the lightweight cellular concrete board 71A and the outdoor lightweight cellular concrete board 51 flows toward the drainage channel 60, and is dropped into a gutter (not shown) attached to the drainage channel 60. By that, it is drained outside.

The unit building 1 having the above configuration is assembled as described below. First,
After erection of pillars and beams in a rectangular parallelepiped at a factory, etc., the interior surface materials such as floor and ceiling materials and the outer wall materials such as outer walls are appropriately adjusted according to the location where they are to be placed. Attach, building units 10, 20, shed unit 3

Further, since the angle member 47 on which each lightweight cellular concrete plate 52B is placed is fixedly supported by the flat bar 46 which is lighter than the small beam 45B, the angle member 4
The inner balcony unit 40 can be reduced in weight and cost can be reduced, as compared with the case where the small beams 45B and the like are provided to support the radiating member 7.

(6) In the unit-type building 1, the balcony unit 70 protruding from the second floor is the shelter unit 3 protruding to the outdoor side Y on the first floor.
0 and is directly mounted on and supported by the same. For this reason, compared with the case where the balcony unit 70 is cantilevered by the inner balcony unit 40 arranged next to it, the support fitting and the support structure for mounting the balcony unit 70 can be simplified. Therefore, the construction of the unit building 1 can be easily performed.

(7) Since the drainage channel 60 is also formed at the joint between the inner balcony unit 40 and the balcony unit 70 that requires waterproofing, the waterproof structure can be integrated into one location, and a new location can be obtained at another location. Drainage 6
Compared with the case where 0 is formed, the waterproof structure can be simplified and the work efficiency of the worker can be improved.

(Second Embodiment) FIGS. 8 and 9 show a structure of a joint portion between an inner balcony unit 40A and a balconi unit 70A of a unit-type building according to a second embodiment of the present invention. Note that, in these modified examples, the same or similar constituent members as those of the above-described embodiment include:
The same reference numerals are used, and the description is omitted or simplified.

This unit type building differs from the unit type building 1 in the first embodiment in the following three points. That is, 1. A drainage channel 60A is provided adjacent to the outdoor lightweight cellular concrete plate 51 at the edge on the balcony side of the inner balcony unit 40A. That is, as shown in FIG. 9, the drainage channel 60A is
It is formed on the A side. 2. On the floor of the balcony unit 70A, a cement plate 71B is used instead of a lightweight cellular concrete plate. 3. Only one outdoor lightweight cellular concrete plate 51 of the inner balconi unit 40 is provided in the direction along the short side floor beam 43B of the unit 40. That is, each of the lightweight cellular concrete plates 51A and 51B of the first embodiment.
Outdoor lightweight cellular concrete board 5 with shorter side dimensions than
1C is used.

In the unit building having such a configuration, the following effects can be obtained in addition to the effects (1) to (6) obtained in the unit building 1 in the first embodiment. (8) The drainage channel 60A is the inner balcony unit 40
Since the drainage channel 60A is arranged on the A side, it becomes possible to assemble this drainage channel 60A together with the main body of the inner balconi unit 40A as a component member of the inner balconi unit 40A in a factory or the like in advance. Therefore, at the construction site, only the work of connecting the inner balconi unit 40A and the balconi unit 70A is performed, and the work of attaching the drainage channel 60A is omitted, and the balcony portion is completed.
The workability of a unit building can be improved.

(9) On the floor of the balcony unit 70A, a cement board 71B weighing less than the lightweight cellular concrete board is laid. Therefore, compared with the case where a lightweight cellular concrete plate is provided, it is possible to reduce the weight of the balcony portion and to facilitate the hanging work of the balcony unit 70A, which also improves the workability of the unit building. Can be improved. (10) An outdoor lightweight cellular concrete board 51C having a larger short side dimension than each of the lightweight cellular concrete boards 51A and 51B.
Is used, the number of the lightweight cellular concrete plates 51C to be installed can be reduced, and the installation work can be reduced.

It should be noted that the present invention is not limited to the above embodiments, but includes other configurations that can achieve the object of the present invention, and the following modified examples are also included in the present invention. .

For example, the installation positions of the drainage channels 60 and 60A are not limited to the first and second embodiments. For example, as shown in FIG. 10, it may be provided along the edge of the floor of the balcony unit 70A on the outdoor side. In such a case, a slightly inclined water gradient is formed on the outdoor side by the outdoor floor of the inner balcony unit 40B and the floor of the balcony unit 70B. That is, the drainage channel 60B is located at the outdoor side Y edge of the balcony unit 70B which is farthest from the unit-type building and where rainwater easily flows.
Is provided, the inner balconi unit 40
Waterproofing of the outdoor floor B and the floor of the balcony unit 70A can be easily performed. In particular, this balcony unit 70
If A is Chianti Balconi (balconi which is cantilevered without providing the shed unit 30 below the Balconi unit 70A), the drainage channel 60C can be arranged at a position away from other units, so that waterproofing work is performed. Becomes easier. Further, a substantially flat surface having no recess or the like is formed widely in the middle of the outdoor floor and the floor. Therefore, when installing a table, a chair, or the like, the installation position can be set freely, and it is possible to form a convenient balcony.

In the above-described embodiment, the rigidity is increased by arranging the flat bar 46 between the lightweight cellular concrete plates 51 and 52 to increase the rigidity. It is not always necessary to provide the flat bar 46, and an adhesive sealing material or the like may be used. Further, it is not always necessary to join the lightweight cellular concrete plates 51, 52 to each other,
What is necessary is just to set suitably according to required rigidity, the dimension of the prepared lightweight cellular concrete board, etc.

Further, in each of the above embodiments, the outdoor lightweight cellular concrete plate 51 is provided with the small beams 45A and the short side floor beams 4.
Although it was provided while forming a water gradient by the brackets 55 and 56 attached to 3B, it is not limited to this. For example, the outdoor lightweight cellular concrete board 51 is directly installed on the upper surface of the small beam 45A or the short side floor beam 43B, and a waterproof sheet in which a water gradient is formed in advance on the upper surface of the outdoor lightweight cellular concrete board 51 is used. A wooden block floor material may be interposed.

Further, in each of the above embodiments, the intermediate beam 44
