Summary of the Invention
Problems to be Solved by the Invention
[0005] However, when there is a distance between an existing building and a newly constructed building, the traffic line for using both buildings may become long.
Means for Solving the Problems
[0006] A method of extension that solves the above problems involves adding a new building to the existing building. Then, common functional parts that will also be used in the new building are extracted from the functional parts of the existing building, and an intermediate building is constructed in the middle of a connecting corridor between the new building and the existing building, with these common functional parts located therein. [Effects of the Invention]
[0007] According to the present invention, buildings with increased floor area can be utilized efficiently. [Brief explanation of the drawing]
[0008] [Figure 1] These are perspective views of the building in the embodiment, where (a) is a perspective view before the extension and (b) is a perspective view after the extension. [Figure 2] This is a side view of the building in the embodiment. [Figure 3] This is a floor plan of the third floor of the building in the embodiment. [Figure 4] This is a floor plan of the fourth floor of the building in the embodiment. [Figure 5] This is a floor plan of the third floor of the relay building in the embodiment. [Figure 6] This is a floor plan of the fourth floor of the relay building in the embodiment. [Figure 7] This is an explanatory diagram of the design process in the embodiment. [Figure 8] This is an explanatory diagram of the flow of movement within a building in an embodiment of the project. [Modes for carrying out the invention]
[0009] The following describes the extension method and one embodiment of the building constructed using this extension method, with reference to Figures 1 to 8. This embodiment describes the construction of an extension to a hospital building. As shown in Figure 1(a), Hospital A1 consists of the existing building 10 (existing structure) constructed on site G1. This existing building 10 has an earthquake-resistant structure that strengthens structural elements such as columns and beams, and resists earthquakes with the strength of the entire building.
[0010] Then, as shown in Figure 1(b), an extension building 20 (new building) will be added to the existing building 10. Here, the extension building 20 will be constructed on site G2, which is adjacent to site G1 across the road. This extension building 20 will be constructed with a base isolation structure that reduces earthquake shaking by installing a base isolation layer in the lower part of the building.
[0011] A connecting corridor will be provided between the existing building 10 and the extension building 20. In this case, a relay building 40 will be constructed on site G1, closer to the existing building 10. Connecting corridors 31 and 32 will then connect the existing building 10 and the extension building 20 via the relay building 40. This relay building 40 will be constructed with an earthquake-resistant structure and will have evacuation staircases 40a and 40b on its sides. The connection between connecting corridor 31 and the existing building 10 will be made with an earthquake-resistant expansion joint. The connection between connecting corridor 32 and the relay building 40 will also be made with an earthquake-resistant expansion joint. The connection between connecting corridor 32 and the extension building 20 will be made with a base-isolation expansion joint.
[0012] As shown in Figure 2, the existing building 10 is a six-story building with floors 11 through 6. Floor 11 of the existing building 10 houses the outpatient reception, floor 12 is the administration office, floor 13 contains the operating rooms and wards, and floors 14 and 15 contain wards. A sub-kitchen will be provided on floor 6, as will be described later.
[0013] The extension building 20 is a six-story building with floors 21 on the first floor and 26 on the sixth floor. The extension building 20 will house an outpatient reception on the first floor (21), an administration office on the second floor (22), an operating room and sub-kitchen on the third floor (23), and wards on the fourth floor (24), fifth floor (25), and sixth floor (26). A balcony (24b) will be provided on the fourth floor (24). To accommodate the specific function of surgery, the operating room in the extension building 20 will be located on the same floor (the third floor in this embodiment) as the operating room in the existing building 10.
[0014] The first floor 41 of the relay building 40 houses an outpatient pharmacy, the second floor 42 houses an inpatient pharmacy, and a cafeteria and a store are provided on the third floor 43. Furthermore, as will be described later, a sub-kitchen is provided on the third floor 43 of the relay building 40, and a main kitchen is provided on the fourth floor 44.
[0015] The passage corridor 31 connects the third floor 13 of the existing building 10 and the third floor 43 of the relay building 40 at the same level without a step. The passage corridor 32 connects the third floor 23 of the extension building 20 and the third floor 43 of the relay building 40 at the same level without a step.
[0016] As shown in FIG. 3, the passage corridors 31 and 32 are connected linearly through the third floor 43 of the relay building 40. As shown in FIG. 4, the fourth floor 44 of the relay building 40 is provided above the third floor 43 of the relay building 40 and the passage corridors 31 and 32. In addition, a plurality of elevators ev2 connecting the respective floors are provided in the third floor 23 and the fourth floor 24. <00000�3> As shown in FIG. 5, a store 43a, a cafeteria 43b, and a sub-kitchen k1 are provided on the third floor 43 of the relay building 40. The passage corridors 31 and 32 are connected to the floor of the passage 430 of the relay building 40 at the same level. The entrances and exits of the store 43a and the cafeteria 43b are arranged to face the passage 430.
[0018] As shown in FIG. 6, a main kitchen k0 is provided on the fourth floor 44 of the relay building 40. An elevator ev4 connecting the first floor 41 to the fourth floor 44 is provided in the relay building 40. By using this elevator ev4, it is possible to move from the main kitchen k0 on the fourth floor 44 to the sub-kitchen k1 on the third floor 43 and the passage 430. <ooo0099> (Design process) Next, the design process for constructing the extension building 20 with respect to the existing building 10 will be described using FIG. 7.
[0020] First, the common functional areas of the existing building and the extension building are extracted (S11). Here, the common functional areas of the existing building 10 that are also used in the extension building 20 are identified. The common functional areas are areas that provide services common to each room in the existing building 10 and the extension building 20. For example, in this embodiment, the extension building 20 has operating rooms and wards. The existing building 10 also has operating rooms and wards. In this case, the operating rooms of the existing building 10 and the extension building 20 are used by patients in the wards of the existing building 10 and the extension building 20, respectively, so they are identified as common functional areas.
[0021] Furthermore, in the existing building 10, a kitchen is envisioned as a common functional area for preparing meals for each patient room in the ward. When meals prepared in one kitchen are distributed to patient rooms in both the existing building 10 and the extension building 20, the kitchen is designated as a common functional area.
[0022] Furthermore, pharmacies (in-hospital and out-of-hospital) that dispense medication for patients in the existing building 10 and the extension building 20 will be designated as common functional areas. Furthermore, the shops used by users of the existing building 10 and the extension building 20 will be designated as common functional areas.
[0023] Next, a connecting corridor is placed between the existing building 10 and the extension building 20 (step S12). Here, floors with high traffic flow between the facilities of the existing building 10 and the facilities of the extension building 20 are identified. For example, traffic flow from the patient rooms of the existing building 10 to the operating rooms of the extension building 20, from the patient rooms of the existing building 10 to the operating rooms of the extension building 20, and from the operating rooms of the existing building 10 to the operating rooms of the extension building 20 are identified.
[0024] Furthermore, when meals prepared in a single kitchen are delivered to patient rooms in both the existing building 10 and the extension building 20, the movement routes from the shared kitchen to each patient room are also identified. Furthermore, the burden of movement in each traffic flow is evaluated. For example, in traffic flows involving the operating room, the burden of movement is significant because patient transport equipment such as portable beds with wheels (stretchers) is used. In traffic flows involving the kitchen, there is a burden of movement because carts are used for serving meals.
[0025] In this way, the floor on which the connecting corridor between the existing building 10 and the extension building 20 is located is determined based on the magnitude of the movement burden in the traffic flow. In this embodiment, a connecting corridor is assumed to connect the 3rd floor 13 of the existing building 10 and the 3rd floor 23 of the extension building 20, based on the traffic flow related to the operating rooms. This connecting corridor is provided at a position where there is no difference in level between the connecting floor of the existing building 10 and the connecting floor of the extension building 20.
[0026] Next, a connecting building is placed on the connecting corridor (step S13). In this embodiment, the connecting building 40 is placed in the site G1 where the existing building 10 is constructed, in the middle of the connecting corridor. Then, the connecting corridor is connected to the same floor as the connecting floor of the existing building 10 and the extension building 20 at the connecting building 40.
[0027] Next, common functional units are placed in the relay building (step S14). Here, common functional units that can be placed in the relay building 40 are identified. In this embodiment, the operating room is a functional space equipped with high-performance equipment and therefore cannot be placed in the relay building 40. Therefore, in this embodiment, the kitchen, which is one of the common functional units, is placed in the relay building 40. Specifically, the main kitchen k0 (centralized cooking facility) of the central kitchen system is placed in the relay building 40. In the central kitchen system, meals are centrally cooked in the main kitchen k0, transported to the sub-kitchens in each building, heated, etc., in the sub-kitchens, and then served to the final destination. Furthermore, pharmacies (both in-hospital and out-of-hospital) will be located in the relay building 40.
[0028] Next, auxiliary functions are placed in each building (step S15). Here, an auxiliary function for storing food prepared in the main kitchen k0 is placed near the serving locations (existing building 10, extension building 20, and intermediate building 40).
[0029] As shown in Figure 8, the food prepared in the main kitchen k0 is transported to the sub-kitchens k1, k2, and k3 using a hotel pan cart. In sub-kitchen k1, the food prepared in main kitchen k0 is heated and served to dining room 43b. In sub-kitchen k2 (first auxiliary function room), the food prepared in main kitchen k0 is heated and transported to each room 10r of the existing building 10 using a reheating cart. In sub-kitchen k3 (second auxiliary function room), the food prepared in main kitchen k0 is heated and transported to each room 20r of the extension building 20 using a reheating cart.
[0030] According to this embodiment, the following effects can be obtained. (1) In this embodiment, an extension building 20 is added to the existing building 10. This extension building 20 is constructed with a seismic isolation structure. As a result, even if the existing building 10, which has a seismic-resistant structure, is damaged by an earthquake or other disaster, the extension building 20 can maintain the hospital functions (building functions).
[0031] (2) In this embodiment, a connecting corridor is provided between the existing building 10 and the extension building 20. The connecting corridor 31 connects the third floor 13 of the existing building 10 and the third floor 43 of the intermediate building 40 on a level surface without any steps. The connecting corridor 32 connects the third floor 23 of the extension building 20 and the third floor 43 of the intermediate building 40 on a level surface without any steps. This reduces the burden of movement between the existing building 10 and the extension building 20.
[0032] (3) In this embodiment, the connecting corridors 31 and 32 are connected in a straight line through the third floor 43 of the relay building 40. This makes it possible to see ahead of the connecting corridor when moving to another building, thus facilitating movement.
[0033] (4) In this embodiment, a shop 43a and a cafeteria 43b are provided on the third floor 43 of the relay building 40. The entrances to the shop 43a and cafeteria 43b are positioned to face the passageway 430. This makes it easy to stop by when moving between other buildings.
[0034] (5) In this embodiment, a connecting corridor is provided between the existing building 10 and the extension building 20 (step S12). In this case, the floors that make up the connecting corridor between the existing building 10 and the extension building 20 are identified based on the magnitude of the burden of movement in the traffic flow. This makes it possible to reduce the burden of movement in the traffic flow between the existing building 10 and the extension building 20.
[0035] (6) In this embodiment, a common function unit is located in the intermediate building (step S14). This allows for the consolidation of overlapping functions in the existing building 10 and the extension building 20, making effective use of floor space. Furthermore, by providing a common function unit in the intermediate building 40 between the existing building 10 and the extension building 20, convenience can be improved for users of either the existing building 10 or the extension building 20.
[0036] (7) In this embodiment, auxiliary functions are provided in each building (step S15). When delivering meals from the main kitchen k0 to each patient room in the existing building 10 and the extension building 20, the delivery is time-consuming because the patient rooms are dispersed. By providing a sub-kitchen near the delivery destination, efficient and timely delivery can be achieved.
[0037] This embodiment can be implemented with the following modifications. This embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically. • In the above embodiment, the present invention was applied to the expansion of a hospital, but the scope of application is not limited to hospitals.
[0038] In the above embodiment, the floor on which a connecting corridor between the existing building 10 and the extension building 20 is located is determined based on the magnitude of the burden of movement in the traffic flow. The criteria for the location of the connecting corridor are not limited to the magnitude of the burden of movement. It may also be located considering building structural factors.
[0039] In the above embodiment, the relay building 40 is equipped with a main kitchen k0 and a pharmacy (in-hospital and outside the hospital) as common functional areas. The functions provided in the relay building 40 are not limited to common functional areas. [Explanation of symbols]
