Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underfloor structure for an apartment house.

[0002]

2. Description of the Related Art Conventionally, as one form of an underfloor structure of an apartment house, a plurality of reverse beams are projected upward on a floor slab that divides each floor, and a floor material is laid horizontally on the reverse beams. There is one in which an underfloor multipurpose space is formed between a floor material and a floor slab by forming a floor surface by means of a floor.

[0003]

However, the above-mentioned underfloor structure has the following problems.

The reverse beam method of installing a reverse beam on the floor slab is
Since an unnecessarily large underfloor storage space is formed and wasteful underfloor storage space is also held, the cost is relatively high.

In the reverse beam construction method, the height of each floor is 500 mm
Since the height is about 600 mm, it is difficult to secure the number of floors and floor area due to the shade regulation and the high-level diagonal regulation.

Since the reverse beam is provided to form the underfloor storage space, the height of each floor becomes high and the number of floors is limited, so that the number of housing units in an apartment is limited.

Since the underfloor storage space is large, there are cases in which it is necessary to install a fire detector due to the application of the Fire Defense Law.

[0008]

Therefore, in the present invention, in an apartment house formed by dividing a floor slab into a plurality of layers, a part of each floor slab is bulged downward to form a concave shape in each floor slab. An underfloor structure for an apartment house is provided which is characterized by forming a multipurpose space forming part.

The present invention is also characterized by the following configuration.

The living room is arranged in a room other than the downstairs room located directly below the multipurpose space forming portion.

[0012] A water supply function room such as a kitchen, a bathroom, a washroom, and a toilet is arranged in a room below the multipurpose space forming section.

The multipurpose space forming portions formed on the floor slabs of the respective floors are arranged alternately in each floor so as to form a staggered pattern in the left-right direction.

The multipurpose space forming section has various uses or various structures as a free space of a resident, or other housing elements are added to these uses and structures.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below.

That is, the underfloor structure of an apartment house according to the present invention is an apartment house formed by dividing a floor slab into a plurality of layers, and a part of each floor slab is bulged downward to form a floor slab. A concave multipurpose space forming portion is formed.

By thus forming the multipurpose space forming portion in each floor slab, it is possible to form a multipurpose space of a required size in a required place without incurring a cost burden.

The multipurpose space forming portion can be effectively used as a multipurpose space such as a storage space, a piping space, and a maintenance space.

Moreover, since the height of each floor does not change, there is no fear of being affected by the shade regulation or the high-level diagonal regulation, and the number of floors and floor area can be effectively secured.

Furthermore, since the height of each floor does not change and the number of floors does not have a limit, the number of housing units in an apartment is not limited.

Further, since the multipurpose space forming portion is not formed to be larger than necessary, it does not apply to the Fire Service Act and does not cause trouble such as obligatory installation of a fire detector.

Here, the living room can be arranged in a room other than the downstairs room located directly below the multipurpose space forming portion.

In this way, it is possible to secure a large ceiling height of the living room, and to form a large living space without giving the occupant a feeling of pressure. as a result,
Good habitability can be secured.

Further, in the room below the multipurpose space forming section, a kitchen, a bathroom, a washroom, and a water supply function room such as a toilet can be arranged.

In this way, the kitchen, bathroom, and
If the ceiling of a water supply function room such as a washroom is too high, it will be difficult to clean and the thermal efficiency will be poor, but such a water supply function room is a multipurpose space forming part that bulges downward. By arranging it in the downstairs room located immediately below, the height of the ceiling part of the water circulation function room can be lowered by the amount that the multipurpose space forming part bulges downward, It is possible to facilitate the cleaning of the same-water surrounding functional chamber, and also to increase the thermal efficiency of the same-water surrounding functional chamber.

Further, the multipurpose space forming portions formed on the floor slabs of the respective floors can be alternately arranged for each floor so as to form a staggered pattern in the left-right direction.

In this way, the load balance of the entire housing complex can be maintained in good condition, and the strength of the housing complex can also be ensured in good condition.

Further, the multipurpose space forming section has various uses or various structures as a free space of a resident, or by adding other house elements to these uses and structures,
A variety of new residential free spaces can be constructed.

Among the living / dining room 7, the Japanese-style room 8 and the Western-style rooms 13 and 14 as living rooms, in this embodiment,
The Japanese-style room 8 is formed in the central part on either the left or right side of the floor 6, while the kitchen 9, the bathroom 10, the toilet 11, and the toilet 12 are formed.
The water-circulating functional chamber 17 is formed in the center portion on the other side of the floor 6 on either side, and the Japanese-style room 8 and the water-circulating functional chamber 17 are arranged laterally adjacent to each other.

Moreover, in the portion of the floor slab 5 located immediately below the Japanese-style room 8, a multipurpose space forming portion 18 is formed which bulges downward to form a concave multipurpose space S1 on the upper surface. A water-surrounding functional room 17 is arranged in a room downstairs located directly below the section 18. 19 is a storage case.

In this way, the multipurpose space forming portions 18 formed on the floor slabs 5 of the respective floors are alternately arranged for each floor so as to form a staggered pattern in the left-right direction, and the load balance of the entire apartment house A is good. In addition, the strength of the housing complex A can be secured well.

At this time, the floor 6 of the living room 8 (a tatami mat in this embodiment)
22 is laid), and an opening / closing body (not shown) is provided below the opening / closing body, and the opening / closing body is opened so that articles can be easily stored in the multipurpose space forming portion 18 arranged directly below the living room 8. In addition to being able to do so, it is possible to easily take in and take out articles as necessary.

Here, kitchen 9, bathroom 10, washroom 11,
And, in the water circulation function room 17 such as the toilet 12, if the ceiling portion 5a of each floor formed by the lower surface of the floor slab 5 is too high, it is difficult to clean and there is a problem that thermal efficiency deteriorates, Since the water circulation function chamber 17 is arranged in a room below the multipurpose space forming part 18 that bulges downward, the multipurpose space forming part 18 bulges downward, The height of the ceiling portion 5a of the water supply function room 17 can be lowered, the cleaning of the water function room 17 can be facilitated, and the thermal efficiency of the water function room 17 can be increased. it can.

Therefore, in order to facilitate cleaning and ensure good thermal efficiency, the height of the ceiling portion 5a of the water circulation function chamber 17 is set to the minimum required height, so that the multipurpose space forming portion 18 is formed. The volume of can be set to the maximum,
It is possible to secure the minimum required multipurpose space S1.

Further, in this embodiment, as shown in FIGS. 13 and 14, the multipurpose space forming portion 18 formed immediately below the Japanese-style room 8 is extended to a position directly below the closet 25, the container 26 and the closet 27. Are formed.

In this way, as shown in FIG. 14, in the closet 27, clothes 29, 30 and the like can be stored in a state of being suspended in two stages, and the multipurpose space of the multipurpose space forming unit 18 can be stored. Since the upper and lower suspension positions can be set lower by the storage space of S1, smaller women and children can easily suspend and remove clothes 29, 30 and the like.

A space for installing the pillowcase 31 and the like can be formed in the upper part of the closet 27 by an amount corresponding to the lowered suspension position of the upper stage, and the storage efficiency (the dead space is small) can be improved. .

Further, in the present embodiment, as shown in FIGS. 15 and 16, the multipurpose space forming portion 18 is also formed immediately below the shoe box 16, and the multipurpose space S1 of the multipurpose space forming portion 18 is formed.

At this time, the shoe box 16 placed at the entrance 15 at the lower floor
Even if the multipurpose space forming part 18 on the floor is located at a position directly above, it is necessary to install the hanging cabinet 24 etc. at a height that can be reached, so that the multipurpose space forming part 18 of the multipurpose space forming part 18 can be installed in the hanging cabinet 24. Presence does not hinder anything.

Further, by utilizing the multipurpose space forming portion 18, it is possible to arrange a drainage pipe (not shown) for piping under the floor with a predetermined gradient, so that the water circulation function room
It is also possible to dispose the 17 in a position away from the pipe space 23, and it is possible to increase the degree of freedom in the layout of the water circulation function room 17.

In addition, the multipurpose space forming section has various uses or structures as a free space for the resident, or by adding other housing elements to these uses and structures,
Various new free-living spaces can be constructed, and other examples of such uses and structures are as follows.

First Embodiment Conventionally, it was necessary to install a cupboard in the kitchen inevitably, or to separately install furniture for storing dishes, so that the kitchen space was disadvantageously narrowed.

In this embodiment, as shown in FIG. 1, the kitchen 1 is installed near the window and the front window facing the kitchen sink 2 is used as the bay window 3 and the space projecting outward is used as the cupboard 4. is there. That is, instead of the conventional feeling of a bay window, a large bay window space is taken and a cupboard 4 is formed inside the bay window 3, and it is formed so that tableware, cooking tools 5, etc. can be stored. The cupboard 4 is provided with an opening / closing door 6 on the kitchen side. In addition, an opaque glass 7 is placed at the back of the cupboard so that it cannot be seen from the outside.
Is installed to partition from the outside, a side wall at the back of the cupboard 4 is provided with a curtain 8 that can be opened and closed, and a door that can be opened and closed is provided.

With such a configuration, the kitchen can be used as widely as possible, the kitchen can be lit as much as possible, and the inside can be brightened, and the volume up to the outer wall of the house can be calculated as the volume of the house. Since it is a thing, the bay window-shaped cupboard is not included in the volume, which is effective when the volume of the house is regulated.

Particularly, in an apartment house, in the case where the ceiling of the kitchen coincides with the recessed floor of the room on the upper floor, the ceiling of the kitchen is slightly lowered, so that the bay window-shaped cupboards make the kitchen a horizontal space. There is an effect that it can be extended to give a sense of laterally expanding space.

Second Embodiment Conventionally, many Japanese-style houses and condominium-type Japanese rooms have a structure in which a closet is formed laterally between floors. Therefore, there is a drawback in that the closet has a narrow horizontal interval, and when a futon is stored, the futon is folded and stored, so that the storage bulk becomes high and a large number of futons cannot be stored.

In this embodiment, as shown in FIG.
The bottom plate 2-2 of 1 is formed at a position slightly higher than the conventional one to form a storage space below it, and the push-in 2-4 located on the lateral side of the floor space 2-1 is divided into two upper and lower storage spaces. The space 2-5 is connected to the storage space below the floor.

Further, lighting can be provided inside the lower storage space 2-3 so that the inside of the storage can be easily used.

A sliding door or a sliding door 2-6 can be provided in the horizontally elongated new lower storage space 2-3 that communicates between the floors formed side by side and below the closet, and a futon or a mat can be provided if necessary. 2-7 can be stored flat without bending.

With this configuration, the space 2-1 between the floors formed side by side and the lower part of the pusher 2-4 form a horizontally elongated lower storage space 2-3, and a storage space is newly added in the same floor area. There is an effect that can be formed.

In particular, in an apartment house, the floor below the lower storage space is formed in a concave shape so that the ceiling of the lower floor is lowered by the amount of the concave of the upper floor, and the concave space is formed. In the case where the upper floors and the lower floors are formed in alternate positions, it is possible to form the lower storage space 2-3 common to the floor space 2-1 and the closet 2-4 on a larger scale.

Third Embodiment Conventionally, when a guest room is provided in a house, the space becomes a dead space when there is no guest, and the bedroom used daily becomes small accordingly, or the bedroom is insufficient in a house with many families. There was a flaw.

In this embodiment, as shown in FIG. 3, the floor 3-
In the state where the movable floor 3-3 is fitted in the concave portion 3-2 by forming the concave portion 3-2 in a part of the concave portion 3-2 and the movable floor 3-3 is fitted in the concave portion 3-2, the floor portion 3-1 Can be used as a flat space, and movable floor 3-3
Is removed from the recess 3-2 of the floor 3-1 and is fixed at a position above the floor 3-1, the inside of the recess 3-2 of the floor and the movable floor 3-3 are connected to the bunk bed 3-a. The present invention provides a movable bed configured as described above.

Reference numeral 3-4 is an elevating mechanism 3-5 for the movable floor 3-3 fitted in the recess 3-2. The rotating screw rod 3-6 is screwed into a screw cylinder 3-7 fixed to the movable floor 3-3. The movable floor 3-3 is moved up and down by rotating the rotary screw 3-6 by the electric motor M.

Reference numeral 3-8 indicates a detachable bed handrail when the movable floor 3-3 is displaced for the bunk bed 3-a, and reference numeral 3-9 indicates the ladder.

Fourth Embodiment Conventionally, in an apartment house, a part of the floor or ceiling is formed as a recess or a protrusion so that the upper and lower spaces of a part of the house can be used highly effectively, and the recess or the protrusion is used. The upper and lower floors are formed in alternate positions, and the concave and convex portions are formed on the floor and ceiling by such a structure, so that the upper and lower floors become part of the daily living space where the upper and lower spaces become narrower. Techniques have been developed that are designed to be used in unused places, such as sheds, washrooms, bathrooms, and aisles.

However, in such an apartment house, it is said that the recesses and protrusions provided alternately on the upper and lower floors are uniformly formed.

Therefore, a so-called condominium dealer who sells each room of such an apartment house has no choice but to set a uniform price for sale, and the purchaser has various changes due to differences in family structure, age, and way of thinking about housing. There may be a case where a concave or convex size with a certain shape is desired, and this principle is not limited to the sale of condominiums, and is the same for rental condominiums and apartments.

In this embodiment, in the upper floor and the lower floor of the multi-story apartment house 4-1, the ceiling portion 4-2 is partially convex so as to be located in an alternate position, and the ceiling portion 4-2 is lowered accordingly. In the construction method in which the floor part is formed in a concave shape and the upper and lower spaces of the upper floors are made larger than this by this amount, the planar size and three-dimensional height of such convex parts 4-a and concave parts 4-b are It is configured differently to satisfy the residents' different wishes and at the same time the price setting of each room is changed according to the space situation.

As shown in FIG. 4, a part of the ceiling portion 4-2 on the first floor is formed so as to be convex downward, and in particular, the area of this convex portion is the widest among the other floors. Is forming. Also,
The floor portion 4-3 on the second floor is formed in a concave shape downward by a lower amount than the ceiling portion on the first floor, and the ceiling portion 4-2 on the second floor corresponding to the concave portion 4-b is more than the concave portion 4-b. A convex area 4-a 'with a small area and slightly deeper than this concave area is formed, and accordingly, the concave area 4-b' on the floor on the third floor has a large space. Becomes an expensive house, and it is possible to provide a freely designed and spacious house space. The floor of the fourth floor is a normal flat floor, and the ceiling has the widest area in each floor and the depth of the recess is the smallest. Therefore, among the floors from the 1st floor to the 4th floor, the 3rd floor has the largest space due to the deep recesses, and the highest selling price and rental price, but the 1st floor has the lowest ceiling space and the lowest price. It becomes cheaper, and in this way, it is possible to form a space that matches the convenience of the occupants in each floor and set the price corresponding to the space instead of the standard price.

In the figure, 4-4 is the stairs provided inside the recess 4-b 'formed in the floor 4-3 on the third floor, and 4-5 is the inner ceiling of the recess 4-b'. The space above the inner ceiling 4-b 'can be used for other purposes.

Fifth Embodiment Conventionally, a technique has been developed in which a concave portion is formed in the floor portion so that the floor portion can be widely and effectively used. Further, the concave portion is formed in an alternate position in each floor, and the ceiling portion in the lower floor is A technology has been developed that can form a convex shape downward correspondingly and freely design the layout of a large residential space and a space that is not.

In the construction of such a structure, as a slab for forming the recess of the floor, concrete slabs are cast in situ to form a slab that is bent in the middle so that a flat floor and a floor of the recess can be formed.

However, it is labor intensive and costly to construct such a slab by in-situ casting of concrete,
In particular, there is a risk that the slab may be cracked due to improper construction, and the structure also has the drawback that it requires a beam and becomes complicated. Therefore, labor saving, cost reduction and certainty of construction have been required in various aspects of the floor recessed structure for such construction.

In this embodiment, a slab-shaped concrete block is precast beforehand to be manufactured in a factory other than the site, carried in and installed on site, and concrete is poured.

5A, 5B and 5C show a concrete block 5-1 which is precast in the form of a slab and has a floor support portion 5-2 for supporting the floor on the left and right sides. Then, in the meantime, a concave space portion 5-3 which becomes a concave portion is formed below the floor support portion 5-2. 5-4
Is a side wall for forming the concave space portion, 5-5 is an inner floor portion forming the concave space portion, 5-6 is an upper end portion of the side wall,
A part of the floor member 5-8 is projected above the floor supporting portion 5-2, and a floor material 5-8 for floor formation is laid on a step portion 5-7 between the upper surface of the floor supporting portion and the upper surface of the side wall upper end portion. Is configured. 5-9
Is a base part that supports the bottom of the concave space part, and 5-10 is an outer wall part that supports the end part of the floor support part. Further, 5-11 is a projecting strip body projecting in the center of the upper surface of the concrete block 5-1, and the concrete engaging hole 5-12 is provided on the end face of the projecting strip body 5-11.
Are formed.

Since this embodiment is configured as described above, the slab corresponding to the site is manufactured in advance in a place other than the site, and the precast slab can be carried into the site and used, so that the construction period can be shortened. The construction cost will be cheaper and it will contribute to labor saving.Because precasting can be conducted by carefully examining it outside the site, there is less risk of construction failure such as on-site casting, and the beam will be eliminated. Therefore, there is an effect that the structure can be easily configured.

Sixth Embodiment Conventionally, the toothbrush has been constructed so that it can be stored by storing it in various storage containers, and easily taken out when necessary.

However, in the present situation, many problems are usually not dealt with since toothpastes that are frequently used are prone to the proliferation of various bacteria.

This embodiment is characterized in that the toothbrush storage case 6-1 has a sterilizing function. That is,
As shown in FIG. 6, the case main body 6-2 may be provided with an ultraviolet irradiation device 6-3 for sterilization, an ozone generator may be provided, or a heating device 6-5 may be provided. Position the UV irradiation part, ozone generation part, and heating part in the part where 6-4 is located.

When the toothbrush 6-4 is taken out from the case, the power is automatically turned off for sterilization. Further, when the toothbrush 6-4 is stored in the case 6-1, the power is automatically turned on. In addition, the power source is automatically turned off after the toothbrush 6-4 is stored in the case 6-1 for a certain period of time, that is, after the time required for sterilization.

In the figure, 6-6 is a fan of the heating device, 6-7 is a storage box for the toothbrush 6-4, 6-8 is a case door, 6-a is a washbasin, 6-b.
Indicates the mirror surface portion of the washbasin 6-a.

The above toothbrush storage case 6-1 is a washbasin 6
It is configured so that it can be arranged on the side of the mirror surface portion 6-b of -a.

Seventh Embodiment Conventionally, since the cord of an electric appliance is led out from an outlet in a room, there is no problem if the position of the outlet is near the electric appliance, but it is located at a position separated from the electric appliance. In some cases, a long code must be used, or a code branched from an existing code must be used, and when there are many electric appliances, the number of codes increases and the room becomes complicated.

In this embodiment, as shown in FIGS. 7A and 7B, a baseboard 7-3 stretched around the lower end of the side wall 7-2 of the room 7-1.
A cord insertion space 7-S is formed inside, and the power cord 7-5 extended from the outlet 7-4 is stored in this space and the baseboard 7-3
It is configured so as to be pulled out from the opening 7-6 provided at an appropriate location of and to be connected to a predetermined electric product 7-b.

That is, the skirting board 7-3 is made a little thicker to form a cord insertion space 7-S therein, and the front board of the skirting board 7-3 is openable and closable in the front direction. No opening
7-6 is formed, and the power cord 7-5 accommodated and inserted in the cord insertion space 7-8 is to be pulled out from the opening for use.

Therefore, when the power cord 7-5 is pulled to an electric appliance located away from the outlet 7-4, first connect the power cord to the outlet and open the front plate of the baseboard 7-3 to open the inside of the baseboard. The power cord is stored in the cord insertion space 7-S of the above, the inside of the cord is stretched, and the tip of the cord is pulled out from the opening 7-6 formed at the predetermined position of the skirting board to close the front plate. The cord pulled out from 7-6 connects to nearby electrical products.

Reference numeral 7-9 designates a hinge portion provided at the lower end of the front plate of the skirting board 7-3 so that the front plate can be opened and closed.

The opening 7-6 may be formed by cutting out a part of the upper edge of the front plate or may be formed with a drawing hole in the front plate. In addition, a plurality of front boards of the skirting board may be independently provided at a fixed length, and each front board may be configured to be independently openable and closable. 7-10 shows a cut portion of the baseboard 7-3.

With this structure, a large number of power cords can be efficiently housed in the baseboard without being scattered in the room, so that the cords are prevented from being accidentally detached from the electric product. It is safe, convenient to use, and has the effect of easily organizing the room.

Eighth Embodiment Conventionally, saving electricity and power consumption has been one of the major goals of energy saving.

As measures for the elderly, there is a demand for measures that enable easy and reliable operation of electric switches.

In this embodiment, as shown in FIG. 8, an entire switch 8-2 which can turn on / off the power of all electric appliances in the house at a door 8-1 of the house by a single operation at a time.
Is provided so that it can be turned off when going out and turned on when returning home.

This overall switch is referred to as an "outgoing switch" or a "homecoming switch", and displays such a display or a display similar to it so that it can be easily visually recognized when going out or coming home.

The overall switch 8-2 is the door 8-of the entrance 8-1.
It will be easy for the elderly to use by installing it inside the house or at the place in the house closest to the door.

Then, particularly for the electric appliances such as the refrigerator 8-4, the personal computer, and the telephone, which cause a trouble in daily life when the power is turned off, they are removed from the whole switch.

With this structure, standby power can be cut off, energy can be saved, and daily life can be prevented.

Ninth Embodiment Conventionally, in an apartment house, when the washing machine is used at night, there is a possibility that the automatic dehydration of the washing machine and the noise at the time of washing may affect the lower floors. There was a flaw that I could not do.

In this embodiment, as shown in FIG.
A waterproof pan 9-2 laid below 9-1 is vibration-proofed.

The waterproof pan 9-2 is a resin pan in which a convex edge portion 9-4 having a folded cross section is formed on the peripheral edge of a rectangular bottom plate 9-3.

Incidentally, the explanatory view shown in FIG. 9 shows the convex edge portion on the front side.
It is the figure which notched 9-4 partially.

As the vibration-proof processing, a vibration-proof sheet 9-5 made of a vibration-proof material is stretched on the front surface or the back surface of the bottom plate of the waterproof pan, and the four corners of the convex edge of the overall rectangular shape or the lower end of the convex edge is formed. A vibration proof body 9-6 is provided on the edge.

The vibration-proof sheet 9-5 and the vibration-proof body 9-6 are made of rubber or foam resin.

By doing so, the noise from the washing machine is blocked at the waterproof pan portion and is not transmitted to the lower floors, so that the washing machine can be used even at night.

Tenth Embodiment Conventionally, in an apartment house, partitions of each floor are divided by slabs to form a required floor plan for each floor.

However, in such an apartment house, pillars and beams are provided at important points. Therefore, it takes a lot of labor and cost to build. Furthermore, there is a drawback in that the use of space is restricted due to the columns and beams, and it is not possible to design the floor plan freely.

In this embodiment, as shown in FIG. 10, a box-shaped concrete frame 10-1 is preliminarily formed in a factory or the like, and this frame is formed in a vertically long shape so that the inside can be arbitrarily partitioned. In addition, a plurality of these vertically elongated concrete frames are arranged side by side in a staggered manner to form an integrated housing 10-2, and a part of the partition walls adjacent to each other is formed in these vertically aligned concrete frames. Deleted 10-3, or formed a recess 10-4 in the adjacent room to expand the space of the living room as much as possible, and formed a space common to a plurality of vertically elongated concrete frames arranged as needed. However, it provides an apartment house as a common use space that can be shared by all residents in the frame.

In this embodiment, the concrete frame 10-1 is formed in advance in a box-culvert-like vertically elongated box shape in a factory or the like, and this concrete frame is carried into the site and arranged in parallel in a number of steps in the vertical direction. It is an integrated housing 10-2. When arranging them in parallel in a staggered manner, the living rooms 10-a formed in the central portion of the vertically long concrete frame are staggered so that they are staggered so as not to be adjacent to each other. The meaning is as follows.

That is, the vertically long concrete frame 10-1
Is divided into three equal parts in the vertical direction and is divided by a floor plate or ceiling plate to form the living room 10-a in the center.If a number of such vertically elongated concrete frames are arranged side by side in the horizontal direction, they are adjacent to the living room. For the space inside the horizontal concrete frame, remove the frame wall to make it a horizontal extension space of the adjacent living room, or make the frame wall concave in the adjacent direction to make it an expansion space of the adjacent living room 10-a. It is a thing.

If necessary, a shared floor extending in the lateral direction can be formed in each divided space provided in a large number of juxtaposed concrete frames so that a shared floor can be used. .

Conventionally, a technique has been developed in which a concave portion is formed in the floor portion so that the floor portion can be widely and effectively used. Further, the concave portions are formed at staggered positions in each floor so that the ceiling portion of the lower floor is lowered accordingly. Although a technology has been developed that can be designed in a convex shape to freely design the layout of a large residential space and a space that is not, in this embodiment, this principle is applied to the vertical box-shaped concrete frame 10-1.
Are arranged to form a convex portion 10-4 in the horizontal direction and used for space expansion in the horizontal direction.

With such a structure, by vertically integrating concrete frames in parallel, there is an effect that a floor plan can be freely designed for the laterally expanded space of each house. Since a concrete frame is used, there is no need to construct columns or beams, so there is an effect that construction is easy and strength can be improved.

Eleventh Embodiment Conventionally, in a standard house, a living room is arranged at a position located on the outer circumference, and the window of the living room is exposed to the outside so that the outside air can be taken in sufficiently. There are many.

Therefore, the facilities around the water are inevitably concentrated in the central part of the house, and the distribution pipes are laid from the central part to the outside of the house. Therefore, it is necessary to provide a space for the distribution pipe for that purpose. There is a problem in that this space becomes higher in the floors, which is disadvantageous in terms of cost, and that the floor layout of the residence is restricted, and that the sound of drainage easily affects the surrounding residence.

In this embodiment, as shown in FIG. 11, of the slabs 11-2 and 11-3 installed on the left and right of the floor of the house, the slab 11-1 located in the approximate center of the house is replaced by the slab adjacent to the slab 11-1. 11-
It is characterized in that it is arranged one step below 2, 11-3, and a drainage pipe for water circulation is housed in the space of the stepped portion.

The space of the stepped portion is used as the piping space 11-S, and the blow-off cylinders 11-4 are formed at both ends of this space 11-S, and the drainage vertical pipe and the ventilation duct common to each floor are housed therein. To do.

Therefore, the drainage pipe, which is drawn out from the lateral direction by crawling through the piping space below the floor, joins the drainage vertical pipe of the blow-through cylinder 11-4 formed at the side end of the house and is discharged to the outside of the house. .

With this configuration, the space for the drainage pipe can be taken with a space, there is no need to raise the floor height, and the floor plan in the house can be freely designed. Since it is stored in the stepped space of the slab, it has the effect of reducing drainage noise and making it difficult to conduct drainage noise to the lower floors.

[0112]

According to the present invention, the following effects can be obtained.

According to the present invention of claim 1, in an apartment house formed by dividing a floor slab into a plurality of layers,
A part of each floor slab is bulged downward to form a concave multipurpose space forming portion in each floor slab.

By thus forming the multipurpose space forming portion on each floor slab, it is possible to form a multipurpose space of a required size in a required place without burdening the cost.

The multipurpose space forming portion can be effectively used as a multipurpose space such as a storage space, a piping space, and a maintenance space.

Moreover, since the height of each floor does not change, there is no concern of being subject to the shadow regulation or the high-level diagonal regulation, and the number of floors and floor area can be effectively secured.

Furthermore, since the height of each floor does not change and the number of floors does not have a limit, the number of housing units in an apartment is not limited.

Further, since the multipurpose space forming portion is not formed larger than necessary, it is not applied by the Fire Defense Law, and the troublesomeness such as obligatory installation of the fire detector does not occur.

According to the second aspect of the present invention, the living room is arranged in a room other than the downstairs room located directly below the multipurpose space forming portion.

In this way, it is possible to secure a large ceiling height of the living room, and to form a large living space comfortably without giving the occupant a feeling of pressure. as a result,
Good habitability can be secured.

According to the third aspect of the present invention, a kitchen, a bathroom, a washroom, and a water supply function room such as a toilet are arranged in a room below the multipurpose space forming section.

In this way, the kitchen, bathroom, and
If the ceiling of a water supply function room such as a washroom is too high, it will be difficult to clean and the thermal efficiency will be poor, but such a water supply function room is a multipurpose space forming part that bulges downward. By arranging it in the downstairs room located immediately below, the height of the ceiling part of the water circulation function room can be lowered by the amount that the multipurpose space forming part bulges downward, It is possible to facilitate the cleaning of the same-water surrounding functional chamber, and also to increase the thermal efficiency of the same-water surrounding functional chamber.

According to the fourth aspect of the present invention, the multipurpose space forming portions formed on the floor slabs of the respective floors are alternately arranged for each floor so as to form a staggered pattern in the left-right direction.

In this way, the load balance of the entire collective housing can be kept good, and the strength of the collective housing can also be ensured excellent.

In the present invention according to claim 5, the multipurpose space forming portion has various uses as a free space of a resident, has various structures, or has various house elements added to these uses and structures. A new free space can be constructed.
