Description

The present invention relates to office buildings such as own buildings and tenant buildings.

For example, a conventional tenant building has a shared zone such as a toilet room and a rest area on the standard floor.

Since the tenant building has a shared zone on the standard floor, there is a limit to the improvement of the effective rate (rentable ratio). Moreover, in such a layout of the standard floor, it is considered that the working style is completed on each floor and the creation of a new network between people and companies is scarce.

An object of the present invention is to provide an office building that can be expected to create a new network between people and companies while greatly improving the effectiveness rate.

In order to achieve the above object, the office building according to the present invention has one or more special floors that are not continuous up and down, and more general floors than the special floors, and the toilet room and rest are on the special floors. The areas are centrally located , and the special floor has two toilet rooms that can be accessed directly from the common corridor and are located far from each other, while the general floor is a general-purpose floor with the same configuration as the standard floor. And a limited floor having a structure different from the standard floor, and the general-purpose floor is not provided with a toilet room that can be directly accessed from the common corridor (claim 1).

In the office building, the outer periphery of the general floor and the special floor is surrounded by a corridor, equipment and equipment and two external stairs are provided on the balcony, and an elevator shaft is located between the two external stairs, and the special On the floor, the common corridor extends in a straight line, the two toilet rooms are each long in the direction in which the common corridor extends, and entrances and exits to the common corridor are provided on both sides in the longitudinal direction thereof. One doorway of each of the toilet rooms may be located near the elevator shaft, and the other doorway may be located near the external stairs that are different from each other (claim 2).

In the office building, a waist wall and a window connected to the upper side of the waist wall are provided along one side of the balcony, a partition portion is extended from the upper part of the waist wall to the outside, and the lower part of the partition portion is the equipment. It will be a storage space for accommodating ventilation equipment as equipment, and an air conditioner will be installed in the ceiling on the core side facing the window to perform air conditioning by jet air flow, and face the ceiling side of the room in contact with the window. The slab is composed of void slabs to eliminate small beams, and a structural girder that also serves as a smoke-proof hanging wall is extended from the air conditioner toward the window to form a double floor in the room and communicate with the accommodation space below the room. In addition to forming an underfloor space, the floor material of the room is provided with a floor outlet capable of blowing out the outside air for ventilation supplied from the ventilation device, and the ceiling of the room is not provided with an air conditioning duct pipe and is a direct ceiling. May be realized (claim 3).

According to the present invention, it is possible to obtain an office building in which the creation of a new network between people and companies can be greatly expected while aiming at a significant improvement in the effectiveness rate.

That is, in the office building of the invention according to each claim of the present application, the effective rate (rentable ratio) is significantly improved by setting the special floor where the toilet room and the rest area are centrally arranged as a shared zone of the entire building. Can be done.

In addition, workers working on the general floor will be encouraged to move to the special floor to use the toilet room, and since there is a rest area on the special floor, people and companies on the special floor. We can greatly expect the creation of a new network between them. Moreover, this effect will be further enhanced in combination with the increase in the number of companies and people who enter the building due to the above-mentioned effect of significantly improving the effectiveness rate.

Furthermore, by centrally arranging the toilet room and the rest area, the labor required for cleaning can be reduced. In addition, considering the installation of the optimum number of toilet appliances for the area and personnel of the entire building, it is better to concentrate the toilet rooms on the special floor as in the present invention, rather than providing the toilet rooms on each floor. It is easy to adjust the number of toilet appliances, and it is possible to make it difficult for excess or deficiency to occur.

In the office building of the invention according to claim 2, the outer periphery of each floor is surrounded by a balcony to facilitate exterior maintenance, and by providing an external staircase on the balcony, it is possible to secure an evacuation passage space. .. In addition, by arranging equipment on the balcony, constructing an air conditioning system that is complete on each floor, eliminating vertical shafts (pipe space, drain space) in the room, and realizing energy supply at the shortest distance or a distance close to it. , It is possible to reduce energy loss such as air conditioning.

In the office building of the invention according to claim 3, since the sunlight from the windows on each floor to the room is restricted by the waist wall and the balcony on the upper floor, the heat load is reduced, the efficiency of the internal equipment is improved, and the office work is comfortable. It is possible to realize a space. Moreover, the space outside the waist wall can be effectively utilized as a space for accommodating equipment without wasting it.

(A) and (B) are longitudinal sectional views in the longitudinal direction and the longitudinal direction which generally show the structure of the office building which concerns on one Embodiment of this invention. (A) and (B) are plan views schematically showing the composition of the general floor and the special floor of the office building. (A) is an explanatory diagram schematically showing the configuration of the general floor, and (B) is an explanatory diagram schematically showing the configuration of the ceiling portion of the general floor.

Embodiments of the present invention will be described below with reference to the drawings.

The office buildings shown in FIGS. 1 (A) and 1 (B) are specified by taking advantage of the advantages of reducing the floor height, which not only saves materials and resources but also facilitates movement between the upper and lower floors. The rest area etc. are concentrated on the floor of.

That is, if the floor height of the conventional general office building is 4.2 m, the floor height of the office building of this example is 3.15 m, that is, the floor height of three-quarters.

The office building of this example has one or more special floors 1 that are not continuous up and down, and a general floor 2 that is larger than the special floor 1 (see FIG. 1 (A)), and a toilet is located on the special floor 1. The rooms 3 and the rest area 4 are centrally arranged (see FIG. 1 (B)). In the examples shown in FIGS. 1A and 1B, only one special floor 1 is provided as an intermediate floor (fifth floor). The general floor 2 refers to a floor other than the special floor 1, and includes a general-purpose floor 2A having the same configuration as the reference floor and a limited floor 2B having a configuration different from the reference floor.

In such an office building of this example, the effective rate (rentable ratio) can be significantly improved by using the special floor 1 in which the toilet room 3 and the rest area 4 are centrally arranged as a shared zone of the entire building. ..

In addition, workers working on the general floor 2 will be urged to move to the special floor 1 in order to use the toilet room 3, and since the rest area 4 exists on the special floor 1, the special floor We can greatly expect the creation of a new network between people and companies in 1. Moreover, this effect will be further enhanced in combination with the increase in the number of companies and people entering the building due to the above-mentioned effect of significantly improving the effectiveness rate.

Further, by centrally arranging the toilet room 3 and the rest area 4, the labor required for cleaning the toilet room 3 can be reduced.

In addition, considering the installation of the optimum number of toilet appliances for the area and personnel of the entire building, the toilet rooms 3 are concentrated on the special floor 1 as in this example, rather than the toilet rooms 3 on each floor. It is easier to adjust the number of toilet appliances, and it is possible to make it less likely that excess or deficiency will occur.

Further, as shown in FIGS. 2A and 2B, in the office building of this example, the outer periphery of each floor (excluding the 1st floor) of the general floor 2 and the special floor 1 is surrounded by the balcony 5, and the equipment is installed on the balcony 5. Equipment 6 and an external staircase 7 are provided.

Specifically, the plan view of the office building of this example has a horizontally long substantially rectangular shape, and the equipment 6 is arranged on the two long sides of the balcony 5, and the external stairs 7 are provided only on one of them. be.

Here, as the equipment 6, as shown in FIGS. 2 (A) and 2 (B) and FIG. 3 (A), the pipe space or the like (PS, EPS) 6a, the distribution board 6b, the outdoor unit 6c, and the dehumidification Examples thereof include a ventilation device (desiccant outside air processing machine) 6d having a function and a humidifying function.

By surrounding the outer periphery of each floor with the balcony 5 in this way, exterior maintenance can be facilitated, and by providing the external stairs 7 on the balcony 5, it is possible to secure an evacuation passage space.

In addition, equipment 6 will be placed on the balcony 5 on each floor, an air conditioning system will be completed on each floor, vertical shafts (pipe space, drain space) will be eliminated in the room, and energy will be supplied at the shortest distance or close to it. By realizing this, it becomes possible to reduce energy loss such as air conditioning. The effective area can be maximized by setting the depth of the balcony 5 to 2 m or less, which is not included in the total floor area under the Building Standards Act.

Further, as shown in FIG. 3A, in the office building of this example, the waist wall 8 and the upper side thereof are along one side of the balcony 5 (the one of the two long sides of the balcony 5 where the external stairs 7 are not provided). A partition portion 10 is provided from the upper part of the waist wall 8 toward the outside, and a storage space 11 for accommodating a ventilation device 6d (an example of equipment 6) is provided below the partition portion 10.

In the office building of this example, the sunlight from the window 9 on each floor to the room is restricted by the waist wall 8 and the balcony 5 on the upper floor, so that the heat load is reduced, the internal equipment efficiency is improved, and the interior is comfortable. It is possible to realize an office space. Moreover, the space outside the waist wall 8 can be effectively utilized as a space for accommodating the equipment 6 without wasting it.

In the example of FIG. 3A, a climber-type blind 12 that also serves as a light shelf that can rise from the waist wall 8 is provided, and a ventilation window 13 is provided above the window 9.

The office building of this example adopts the following configuration in order to reduce the floor height.

As shown in FIG. 3A, an air conditioner (for example, an induction unit air conditioner using the Coanda effect) 14 is installed in the ceiling on the core side facing the window 9, and air conditioning is performed by a jet stream 15. In this example, the slab facing the ceiling side of the room is composed of a void slab 16 to eliminate the small beam, and the structural girder 17 that also serves as a smoke-proof hanging wall is directed from the air conditioner 14 toward the window 9 (on the balcony 5). Since it extends (parallel to the lateral direction), the jet stream 15 flows efficiently without being hindered by the unevenness of the ceiling.

On the general floor 2, the air conditioner 14 is arranged on the ceiling of the corridor 18. On the other hand, on the special floor 1, the air conditioner 14 may be arranged on the ceiling of the corridor 18, or may be arranged on the ceiling of the toilet room 3. This arrangement also facilitates a method of directly injecting outside air into the air conditioner 14 for processing.

Ventilation can also be done by underfloor blowing. That is, as shown in FIG. 3A, the room is a double floor such as an OA floor, and the underfloor space 20 is formed below the room 19. The underfloor space 20 communicates with the accommodation space 11, and the ventilation outside air 21 supplied from the ventilation device 6d can be blown out from, for example, a variable air volume type floor outlet (not shown) provided on the floor material 22. It has become.

With the above configuration, no air conditioning duct piping is provided on the ceiling of the room, and the refrigerant or cold / hot water piping 23 is fitted to the ceiling slab to realize a straight ceiling. Specifically, as shown in FIG. 3B, partition guide rails 24 extending in parallel with the structural girder 17 are provided at regular intervals on the ceiling of the room, and for example, each partition guide rail 24 holds the pipe 23. .. Then, the lighting fixture 25 is held by a part of the partition guide rails 24.

In FIGS. 1A and 1B, 26 is a seismic isolation pit. However, the office building of the present invention does not necessarily have such a seismic isolation structure (may be a non-seismic isolation structure).

It goes without saying that the present invention is not limited to the above-described embodiment, and can be variously modified and implemented without departing from the gist of the present invention. For example, the following modification examples can be given.

In the above embodiment, the floor height is reduced, but the floor height reduction is not essential. For example, it is conceivable to install an escalator to facilitate the movement of the upper and lower floors so that the movement of the upper and lower floors will not be difficult even if the floor height is high.

The special floor 1 may be provided on the top floor or the bottom floor. However, from the viewpoint of reducing the number of special floors 1 as much as possible while considering accessibility to special floors 1, it is better to provide special floors 1 only at the position of the middle floor sandwiched from above and below by general floors 2. Preferably, when a plurality of special floors 1 are provided, it is rational to provide one or more general floors 2 between the plurality of special floors 1.

In the above embodiment, the equipment 6 is not arranged on the outer peripheral portion of the elevator shaft 27 on the balcony 5, but it may be arranged.

Needless to say, the modifications given in the present specification may be combined as appropriate.
