Abstract

PURPOSE:To shoot common troubles particularly regarding heat insulation, sound insulation, leakage, etc., and the limited alteration of room planning in a multiple dwelling house, and to conduct an efficient design in a wall type reinforced concrete building. CONSTITUTION:Peripheral walls are formed in size thicker than boundary walls regarding a wall type reinforced concrete building with the peripheral walls 4 forming the outer circumference of the whole building and the boundary walls 5a, 5b forming the boundaries of each dwelling unit 3 in the building. Accordingly, the peripheral walls having a greatest effect on heat insulation, sound insulation, leakage, etc., can further be firmed, and a wing wall as a constraint at the time of the change of room planning can be unnecessitated, thus attaining an expected object.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall-type reinforced concrete structure, and more particularly to a wall-type reinforced concrete structure suitable for an apartment house.

[0002]

2. Description of the Related Art A conventional wall-type reinforced concrete building is basically designed to have the same thickness for all bearing walls such as the outer peripheral wall of the entire building and the boundary walls that partition each block in the building. This was also the case for multi-family houses. An example thereof is shown in FIG. This conventional example is an example of an apartment house having a structure in which a common corridor 21 and a veranda 22 having a continuous structure are projectingly provided on the outer peripheral portion in the girder direction, and the outer peripheral wall 23 and each dwelling unit 24, 24, ... Boundary walls 25, 25, which are divided according to directions, are each formed to have a thickness of about 180 mm, and in order to secure a necessary amount of wall, every other boundary wall 25 and a part of the outer peripheral wall 23 are sleeve walls. 26 is projected. The outer wall 23 has a window opening 27 and a door opening 28, and a recessed portion is a meter box M for accommodating meters such as electricity, gas, and water.

By the way, such a wall structure having a uniform thickness has a problem that when the boundary wall exceeds the amount of wall required for earthquake resistance, it is overdesigned and the concrete is apt to be wasted. As a matter that tends to be a problem in the case of a house, for example, there is a problem that problems such as heat insulation, sound insulation, and water leakage are likely to occur, or sleeve walls protruding into each dwelling unit as in the above conventional example are provided to secure the wall amount. Since there are many cases where it is necessary, there is a problem that it is easy to be restricted by changes in the floor plan accompanying changes in the life cycle.

[0004]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to reduce troubles such as heat insulation, sound insulation, water leakage, etc., which are particularly problematic in multi-dwelling houses, and restrictions in changing the floor plan, for wall type reinforced concrete structures. It is to provide a structure that can be solved and can be designed efficiently.

[0005]

In order to achieve the above object, the present invention provides a wall-type reinforced concrete structure including an outer peripheral wall forming an outer periphery of the entire building and a boundary wall forming a boundary between blocks in the building. In a building, the outer peripheral wall is formed thicker than the boundary wall.

As a result, since the outer peripheral wall, which has the greatest influence on heat insulation, sound insulation, water leakage, etc., can be made stronger, it is possible to make the building stronger against heat insulation, sound insulation, water leakage, etc., and also the entire building. As a result, an efficient design can be achieved without increasing the amount of concrete. Further, since the outer peripheral wall is made stronger, the sleeve wall projecting into the block is not required, so that it is possible to reduce restrictions when changing the floor plan due to a change in the life cycle.

With regard to a building having such a structure, by using a thick outer peripheral wall as an earthquake-resistant wall, it is possible to reduce the amount of concrete in the entire building, and it is possible to make the design more efficient. .

Further, in a building having such a structure, the boundary walls are arranged at a constant interval in the beam direction, and the boundary walls are alternately arranged to have a thickness Ta and a thickness Tb (Ta>
It is even more preferable to use a structure in which the boundary wall having a thickness of Ta is formed of Tb) and the boundary wall having a thickness of Ta is an earthquake resistant wall, because the concrete amount of the entire building can be further reduced.

EXAMPLES Examples of the present invention will be described below. First Embodiment (FIG. 1) This embodiment is an example of an apartment house, and has a structure in which a common corridor 1 and a continuous veranda 2 are projected in the girder direction in the outer peripheral portion in the same manner as the conventional example. , And the dwelling units 3, 3, ... Are equally divided in the direction of the girder. The outer peripheral wall 4 is formed to have a thickness of about 200 mm, while each dwelling unit 3, 3, ... Has a thickness of 150.
mm and the boundary walls 5a, 5a, ... And the boundary walls 5b, 5b ,. Then, the outer peripheral wall 4 and the boundary walls 5b, 5
b, ... are formed on the seismic resistant walls, and the boundary walls 5a, 5
a, ... Are formed on a normal bearing wall.

In the case of this embodiment, the total length of the outer peripheral wall 4 and the total length of both boundary walls 5a, 5b are substantially equal. Therefore, the average wall thickness is about 174 mm according to the calculation considering the window openings 6, 6, ... In the outer peripheral wall 4, the entrance opening 7, and the opening for the meter box M, and the total amount of concrete is saved as compared with the conventional structure. You can do it.

Second Embodiment (FIG. 2) This embodiment is a modification of the first embodiment. In the first embodiment, the boundary walls 5a, 5a, including the surrounding wall of the meter box M, ...
, And the boundary walls 5b, 5b, ... Between them are made thicker. On the contrary, the boundary walls 10a, 10a ,. 10b, ... are thinly formed. The other points are the same as in the first embodiment.

INDUSTRIAL APPLICABILITY As described above, the wall-type reinforced concrete building according to the present invention has a stronger outer peripheral wall, which has the greatest influence on heat insulation, sound insulation, water leakage, etc., than other walls, and thus becomes stronger. Therefore, it is possible to improve the heat insulating property, sound insulating property, water leakage resistance, etc., and it is possible to avoid an increase in the amount of concrete in the building as a whole, so that an efficient design can be achieved. In addition, since the outer peripheral wall is made stronger, the sleeve wall of the boundary wall can be eliminated, and restrictions when changing the floor plan due to changes in the life cycle can be reduced.
