Description

  The present invention relates to a frame structure of an apartment house.

  In a housing complex in which a plurality of dwelling units are arranged in parallel in the horizontal direction, stacked in the vertical direction, and a common corridor is provided on one side of the dwelling unit group arranged in parallel on each floor, a slit ( Patent Documents 1, 2 and the like are known as providing an open space on the side opposite to the common corridor of the building. These proposals are superior in terms of air permeability to the dwelling units and securing lighting as compared to the case where each dwelling unit is arranged in parallel through one door wall, There are several problems with the building structure.

  FIG. 8 is a schematic diagram of a typical multi-family housing structure. 1 is a dwelling unit arranged in parallel, 4 is a column, 5 is a beam, and 6 is a seismic wall. Reference numeral 2 denotes a common corridor directed to one side of the dwelling units arranged in parallel. The construction surface in the X direction (girder direction), which is the direction in which the dwelling units 1 are arranged in parallel, is a ramen structure with columns 4 and beams 5, and the construction surface in the Y direction (direction between beams), which is perpendicular to this, is It is a ramen structure with a seismic wall in which a seismic wall 6 is provided in addition to a column 4 and a beam (not shown).

  The advantage of this frame structure is that it has a seismic wall 6 so that it can not only handle the input load in the Y direction (earthquake, etc.) firmly, but can also flexibly handle the bending load resulting from the rotation of the entire building. 4 and the cross-sectional area of the beam 5 can be reduced by an amount corresponding to a small stress load on the beam 5.

  On the other hand, since the seismic wall 6 bears part of the bending stress of the pillars and beams as described above, providing an opening such as a window in the seismic wall 6 reduces the strength of the seismic wall 6 itself. It is also a point that the opening area that can be provided in the earthquake-resistant wall 6 is limited.

  Therefore, in a frame with a frame structure in the Y direction (direction between the beams) and a ramen structure with earthquake-resistant walls, an attempt is made to provide a slit (an open space on the side opposite to the common corridor 2 of the building) between the dwelling units. Then, as shown in FIGS. 9 and 10, the size of the openings a and b facing the slit 3 is limited. In the figure, 8 is a common space connected to the common corridor 2.

  Since the slit 3 between the dwelling units 1 is originally a technique for further improving ventilation and lighting securing to each dwelling unit 1, a frame structure advantageous for arranging the dwelling units 1 in parallel is also a part of Patent Document 1. In the frame configuration in which the door wall is a seismic wall, the opening area facing the slit 3 is small, so that the advantage of providing the slit 3 is halved.

  As a frame structure in which the opening to the wall can be freely provided, there is a method of making a ramen structure in both the X direction and the Y direction as shown in FIG. Since this frame form basically corresponds to the load by the pillars 4 and the beams 5, in principle, all parts other than the pillars 4 and the beams 5 can be openings.

  Therefore, as shown in FIG. 12, in a frame having a ramen structure in both the X direction and the Y direction, when the slit 3 is provided between the dwelling units 1, an opening for effectively using the slit 3 can be freely arranged. it can.

However, in this frame form, since there is no earthquake-resistant wall that bears stress on the columns 4 and 5, the columns 4 and beams 5 naturally bear stress on all loads, resulting in the columns 4 and beams. There is a problem that the cross-sectional area of 5 becomes large (Patent Document 2).

  The present invention has been made in view of the above-mentioned problems. The purpose of the present invention is to firmly handle input loads in the direction of beams (earthquakes, etc.) when providing slits between dwelling units arranged in parallel. In addition to being able to cope with bending loads caused by the rotation of the entire building, the cross-sectional area of the columns and beams can be reduced by the amount of less stress on the columns and beams, and the opening facing the slits can be enlarged. Therefore, it is to provide a frame structure of an apartment house that makes it easy to secure ventilation and lighting using a slit.

  In order to achieve the above object, technical measures taken by the present invention are as follows. That is, in the frame structure of an apartment house according to the present invention, a plurality of dwelling units are arranged in parallel in the horizontal direction, stacked in the vertical direction, a common corridor is provided on one side of the dwelling unit group arranged in parallel on each floor, and It is a frame structure of an apartment house in which slits are provided between units that are arranged side by side, and the X-direction structure that is the direction in which the units are arranged side by side is a ramen structure that consists of columns and beams, and is perpendicular to this. The construction surface in the Y direction is basically a ramen structure with a seismic wall having a seismic wall in addition to columns and beams, and only the construction surface in the Y direction facing the slit is a ramen structure composed of columns and beams. An intermediate column not having an X-direction beam is provided on the construction surface.

  The intermediate column is a column for balancing the stress. Since no beam in the X direction is installed, the intermediate column is not necessarily arranged symmetrically on both sides of the slit as long as it is close to the middle in the Y direction. It is not necessary to do so, and some position changes are possible according to the floor plan of the dwelling units on both sides.

  According to the above configuration, the presence of the earthquake-resistant wall on the surface in the Y direction can not only firmly cope with input loads in the Y direction (earthquakes, etc.), but can also withstand bending loads resulting from the rotation of the entire building. Since it can respond, the cross-sectional area of the column or beam can be reduced by the amount of less stress load on the column or beam.

  In addition, only the Y-direction structure facing the slit provided between the dwelling units is a ramen structure consisting of pillars and beams, and it is a frame in which openings such as windows can be set freely, and the wall facing the slit is Securing of used lighting and ventilation becomes easy.

  FIG. 1 is a plan view for explaining a basic form of a frame structure of an apartment house according to the present invention. In this frame structure, two dwelling units 1 are arranged in parallel in the horizontal direction, stacked in the vertical direction, a common corridor 2 is provided on one side of a group of dwelling units arranged in parallel on each floor, and the dwelling units are arranged in parallel 1 is a frame structure of an apartment house provided with a slit (open space on the side opposite to the common corridor 2 of the building) 3 between the X direction (direction in which the dwelling units 1 are arranged in parallel) The structural surface in the girder direction is a ramen structure composed of the beam 4a and the beam 5 in addition to the column 4 and the beam 5, and the structural surface in the Y direction (direction between beams) perpendicular to this is basically the column 4 In addition to the beam and the beam (not shown), the ramen structure with the earthquake-resistant wall 6 having the earthquake-resistant wall 6 is used, but only the Y-direction composition surface facing the slit 3 is the ramen structure including the column 4 and the beam 5. An intermediate column 7 having no X-direction beam is provided on the construction surface. Reference numeral 8 denotes a concrete slab, which is a common space connected to the common hallway 2.

  If the basic structure shown in FIG. 1 is taken as one unit and is continued in the horizontal direction, a frame structure of a housing complex with a large number of houses as shown in FIGS. 2 and 3 is obtained. Further, in order to continue in the horizontal direction with the basic structure shown in FIG. 1 as a unit, it is not always necessary to be linear, and as illustrated in FIG. It can be designed in a shape and can be used for various site shapes.

  According to these configurations, the presence of the seismic wall 6 on the surface in the Y direction not only can firmly cope with input loads in the Y direction (such as earthquakes), but is also strong against bending loads resulting from the rotation of the entire building. Therefore, the cross-sectional area of the column 4 or the beam 5 can be reduced by the amount of less stress load on the column 4 or the beam 5.

  Further, only the Y-direction structural surface facing the slit 3 provided between the dwelling units 1 is a frame structure having a pillar 4 and a beam 5 and is a frame in which an opening such as a window can be freely set. Securing lighting and ventilation using the wall facing

  FIG. 5 shows a specific example in which the floor plan of each dwelling unit is arranged in the frame structure of an apartment house according to the present invention. The intermediate column 7 is continuous across the layers of the apartment building, but is a column for balancing the stress, and since no beam in the X direction is installed, it should be close to the middle of the construction surface in the Y direction. For example, it is not always necessary to arrange symmetrically on both sides of the slit 3, and in the example of FIG. 5, the positions of the intermediate pillars 7 are asymmetrically arranged on both sides of the slit 3 in accordance with the layout of the dwelling units 1 on both sides. is there. 6 is a schematic view taken along the line AA in FIG.

  In FIG. 5, E is a front door, BR is a Western-style room such as a bedroom, JR is a Japanese-style room, LDR is a living dining room, K is a kitchen, U is a washroom, and UB is a bathroom. On the wall 9 facing the slit 3, as an example of an opening, a window 10 of a bathroom UB, a window 11 of a kitchen K, a Western room BR, a light window 12 of a living dining LDR, and the like are provided. 13 is a balcony provided on the opposite side to the common hallway 2. The common space 8 connected to the common corridor 2 is configured as a pouch. Reference numeral 14 denotes a door of the entrance E. In the western room BR facing the slit 3, a normal sliding window 15 is provided in a part facing the balcony 13. In the example of FIG. 5, the handrail 16 is provided at the inner end of the common space 8 facing the slit 3, but a wall having a window that allows ventilation and lighting may be provided.

  Since the wall 9 facing the slit 3 is not a seismic wall, in the case of the seismic wall, not only a large opening, but also various shapes can be realized. For example, as shown in FIG. 6, the window 11 of the kitchen K can take in more light from the slit 3 by using the glass block 11b in the lower part in addition to the normal one-sided window 11a. Also, in the light window 12 of the Western-style room BR, the entire surface of the opening is also formed by the glass block 12a, so that not only much light can be taken into the Western-style room BR but also direct view from the dwelling unit facing through the slit 3 is prevented. Privacy.

  FIG. 7 shows a frame structure when the frame structure shown in FIG. A feature of this frame structure is that a slab 13a and a slab 13b are provided continuously to the beam 5a constructed on the balcony 13 side with respect to the slits 3 between the dwelling units arranged in parallel.

  This is because the structure of FIG. 1 has a concrete slab 8 and a beam 5b, which are common spaces connected to the common corridor 2, whereas the balcony 13 has only the beam 5a. Then, the stress balance is poor, and excessive stress concentration can be considered on the beam 5a on the balcony 13 side. Therefore, by providing the slab 13a and the slab 13b as the reinforcing members of the beam 5a, the purpose is to achieve the matching of the stress balance.

  Therefore, the slab 13a is provided in the construction surface constituted by the columns 4, 4, 4, 4, the beams 5, 5, the beam 5a, and the beam 5b constituting the slit 3, or the slab 13b is provided continuously with the balcony 13. In addition, whether to provide both the slab 13a and the slab 13b is set as appropriate, the width and thickness of the slab 13a and the slab 13b are also set appropriately, and a reinforcing member for the beam 5a is provided, so that the structure shown in FIG. Facilitates high rise.
