Abstract

<P>PROBLEM TO BE SOLVED: To obtain a space giving a sense of freedom to a resident without giving a sense of oppression by achieving a required strength without installing in an opening section a structural member forming a protrusion from a ceiling or a floor. <P>SOLUTION: An apartment division wall 1 is a bearing wall, and a beam 21 installed above the wall 1 has a width same as the thickness of the division wall 1 so that the beam is prevented from protruding sideward from the division wall 1. Wall columns 25 perpendicular to the division wall 1 are parallelly provided in the center of the division wall 1, and the columns 25 together with the division wall 1 constitute an H-shaped reinforcement structure 5. A slab 4 on the opening side is supported by the division wall 1 and the reinforcement structure 5, and does not have a member protruding in the height direction of the ceiling and the floor. Thus, an open space is provided. Not every division wall 1 is provided with the column 25, but every other division wall 1 is provided with the column 25 so as to produce a large space. Thus, the freedom in floor plan is raised. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to an apartment house in which reinforced concrete or steel-framed reinforced concrete dwelling units are connected in the lateral direction, and is provided with a member that protrudes from the opening surface, is excellent in daylighting and ventilation, and provides a sense of openness to residents. About.

  Conventionally, a reinforced concrete structure or a steel-framed reinforced concrete structure generally has a rigid frame structure composed of columns 3 and beams 2 as shown in FIG. 4, but the beam width and beam formation are increased to obtain the required strength. Will protrude to the indoor side, the height of the opening is limited and the opening cannot be made large, giving the occupant a feeling of pressure, lack of openness, and insufficient lighting and ventilation There's a problem.

In order to solve such a problem, a flat slab structure has been proposed, but the flat slab is also used as a beam that also bears a horizontal force, and it must be quite thick and costly. is there. Moreover, although the structure of the reverse beam shown in FIG. 5 is proposed, the whole opening cannot be taken.
In Patent Document 3 (Japanese Patent Laid-Open No. 2002-121924), as a housing complex building, a high-rigidity core reinforcing structure 5 including a seismic wall is provided at the center of the building, and a slab is provided around the reinforcing structure 5. Although what supports the slab 4 is proposed, since the beam 2 which receives the slab 4 is required in the outer peripheral part of the building, a large opening could not be obtained. (See Figure 6)

  The object of the present invention is to provide the necessary strength as a structure without providing a structural member having a large cross section that protrudes from the ceiling or floor in the opening, and as a result, there is no feeling of pressure and is open to the occupant. It makes you feel like a space.

It is a reinforced concrete or steel-framed reinforced concrete apartment house, and is provided with a slab by providing a door boundary wall for partitioning each door and a reinforcing structure disposed at the center of each door so that a large opening can be set.
Since the slab is supported by the door wall, the reinforcing structure, and the beam extending there from, there is no projecting member on the opening side of the building, and there is no projecting member on the floor surface. A space composed of a ceiling and a flat floor is formed, so that the degree of freedom of the layout can be increased and the building can be given an open feeling.
When the thickness of the doorway wall, which is a load bearing wall, is the same as the width of the beams provided above and below it, the space can be widely used because the beam does not protrude from the doorway wall.

The present invention will be described based on examples.
Example 1
As shown in FIG. 1, a flat frame structure and a front view, the building is a reinforced concrete or steel-framed reinforced concrete apartment house, in which the dwelling units are continuous with a wall as a boundary. This embodiment assumes up to about 10 stories, but can also be applied to buildings with higher floors.

The door wall 1 is a load bearing wall having a wall thickness of 200 to 300 mm. The width of the beam 21 provided on the upper wall is the same as the wall thickness of the door wall 1 so that the beam extends laterally from the door wall 1. It does not protrude, and columns 31 and 32 are provided at both ends.
Furthermore, no beam is provided between the columns 31 on the opening side, and the slab 4 is supported by the door wall 1, the wall column 21, and the beam 22, and is a member in the height direction of the ceiling and floor. Does not protrude, and an open space is obtained. The reduction in strength due to the omission of the beam on the opening side is designed to be compensated for the entire structure, but it is reinforced by appropriate means such as the use of high-strength reinforcing bars or an increase in the amount of reinforcing bars.

  A wall column 25 is provided in the center of the door wall 1 at a right angle to the door wall 1 in parallel, and the door wall 1 constitutes an H-shaped reinforcing structure 5. The wall pillars 25 are not provided on all the boundary walls 1, but are installed every other wall so that a large space can be obtained, thereby increasing the degree of freedom of the floor plan. A beam 22 is provided in the extending direction of the wall column 25 up to the other door wall 1.

As shown in FIG. 2, the slab 4 is structurally designed to be supported three-way by a beam 21 provided on the doorway walls 1, 1 and a beam 22 extending from the wall column 25.
In this embodiment, a beam protruding from the slab 4 is not provided in one opening (on the veranda side), and a beam 22 having a larger beam than the slab thickness is provided in the opening on the opposite side of the veranda. In both cases, the beam may not protrude from the slab.
By adopting such a frame structure, the lateral force is received by the load-bearing wall 1, the beam 21, the wall column 25 and the beam 22, and the slab thickness can be made thinner than the flat slab. A building can be built.

Example 2
As shown in FIG. 3, the reinforcing structure 5 provided in the doorway is a core structure in which the load-bearing wall is formed in a quadrangular shape, and the reinforcing structure 5 can resist the external force acting on the building. Since the pillar 36 is provided between the pillars 31 on the opening side and the beam 22 is provided between them, the beam 22 protrudes from the ceiling, but this can be dealt with by making a Japanese-style room or the like.
The opening on the opposite side is a reverse beam 24 so that the beam does not protrude from the ceiling, so that a living environment with a sense of openness can be provided as a whole.

In a reinforced concrete or steel reinforced concrete apartment house, it is a reinforced concrete or steel reinforced concrete apartment house that receives slabs by the door wall separating each door and the central bearing wall placed in the center of each door, and on the opening side Is designed so that a large opening can be set without providing a beam.
Since the slab is supported by the door wall and the central bearing wall, the beam does not protrude on the opening side of the building, and there is no member that protrudes on the floor surface. The constructed space is formed, and the degree of freedom of the layout is increased, and the building can be provided with an open feeling.
