Abstract

PURPOSE:To relax the restriction of building design by fixing a shape steel member requiring reinforcement and the foundation of a unit structure body through reinforcing material around the outer periphery of the unit structure body which is framed of a plurality of shape steel members something like a box shape. CONSTITUTION:In a two-storied unit house 1, a building side wall 4 to hold a corner part 3 in cooperation with a balcony 2 is provided with an opening 5. Next, a reinforcing structure part 7 is provided so that the existance of the opening 5 may not reduce the strength of the house 1, and composed of a base 9 to fasten the structure part 7 to a foundation 8 with bolts B, a pair of supports 10, and a beam constructed between the supports 10, 10. Thus the restriction of the design of the house 1 can be relaxed with reinforcement executed on the structure body without causing the structure part 7 to close the side of the structure body, namely the opening 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing structure for a unit structure used in a unit building.

[0002]

2. Description of the Related Art In a unit building, there is known a unit structure body (hereinafter, simply referred to as a structure body) of a ramen structure in which a steel column and a beam member (both shaped steel members) are framed by welding.

In this type of structure, a joint piece (joint member) is welded and fixed to each steel column, and a beam member is inserted into this portion to further weld and fix a double-structured portion. In addition, bolts are also used to connect the upper and lower floors to ensure the connection of each connecting portion.

With such a structure, the external force due to an earthquake or a typhoon is not concentrated in one place, and the entire structure is allowed to bear the active force to the foundation to improve the strength of the entire structure. I am trying to

By the way, the form of a building is individual, and additional reinforcement (improvement in anti-eccentricity performance, rigidity, etc.) is often required. In such a case, for example, Japanese Patent Publication Sho 61-
As shown in Japanese Patent No. 42061, a sub-ramen structure as a reinforcing member is erected between upper and lower beam members.
This sub-ramen structure is generally provided inside the structure.

[0006]

However, in the above-described reinforcing structure, at least a part of the reinforcing material is positioned so as to block the side surface of the structure, so that when ancillary equipment such as a garage is installed, the garage is not installed. The openings may not be taken sufficiently, and other similar design restrictions may occur.

The present invention was created in consideration of such circumstances, and an object thereof is to provide a reinforcing structure for a unit structure which can alleviate restrictions in building design.

[0008]

In order to achieve the above-mentioned object, the invention according to claim 1 is the above-mentioned shaped steel material requiring reinforcement from the outer periphery of a unit structure in which a plurality of shaped steel materials are framed in a box shape. The base of the unit structure is fixed by a reinforcing material.

Further, the invention according to claim 2 is characterized in that the reinforcing member is fixed to the top end level of the foundation of the unit structure.

[0010]

According to the reinforcing structure for a unit structure according to claim 1, when additional reinforcement is required for a specific shape steel material, the periphery of the unit structure is provided between the shape steel material and the foundation. Therefore, since the shaped steel material requiring reinforcement and the foundation of the unit structure are fixed by the reinforcing material, the reinforcing material does not block the side surface of the structural body.

Therefore, it is possible to relieve the restrictions on the building design due to the presence of the reinforcing material while reinforcing the structure.

Further, according to the reinforcing structure of the unit structure of the second aspect, since the reinforcing member is fixed to the top end level of the foundation of the unit structure, the construction of the foundation work can be simplified. , Its reinforcement will also be reliable.

[0013]

Embodiments of the reinforcing structure for a unit structure of the present invention will be described below with reference to the drawings.

1 to 3 show a first embodiment of the present invention. In FIG. 3, reference numeral 1 denotes a two-story unit house, which is a unit structure of a rigid frame structure in which a steel frame column and a beam member (each of which is a shaped steel member) are framed by welding (as described above, hereinafter, simply a structure member). That is).

The two-story unit house 1 has an overhang type balcony 2.

An opening 5 is provided in the side wall 4 of the building which sandwiches the corner portion 3 together with the balcony 2.

The opening 5 has a length substantially equal to the width of the building side wall 4, and four sash glasses 6 are attached thereto.

Reference numeral 7 is a reinforcing structure provided so that the strength (particularly, eccentricity resistance and rigidity) of the two-story unit house 1 does not decrease due to the presence of the opening 5, and the outer periphery of the two-story unit house 1 is provided. It is located around. The balcony 2 is firmly held regardless of the reinforcing structure 7.

As shown in FIGS. 1 and 2, the reinforcing structure 7 includes a base 9 fastened to a foundation 8 by a bolt B, and a pair of columns 10 standing upright from the base 9.
A built-in ramen structure including a beam 11 installed between the columns 10 and 10 is incorporated.

Numerals 12 and 13 are steel frame columns and beam members which constitute a part of the structure of the two-story unit house 1.

In the case of this embodiment, since the building side wall 4 has the opening 5, it is necessary to add additional reinforcement to the steel frame column 12. However, between the steel frame column 12 as the type steel material and the foundation,
Since the reinforcing structure 7 is fixed from around the outer periphery of the unit structure, that is, around the outer periphery of the two-story unit house 1, the reinforcing structure 7 does not block the side surface of the structure, that is, the opening 5. While the structure is being reinforced, it is possible to relax the design constraint of the two-story unit house 1 due to the existence of the reinforced structure portion 7. Moreover, below the balcony 2, as shown in FIG. 3, a utility space U having the reinforcing structure 7 as a pair of sleeve walls can be obtained, and it is possible to develop variations in building design. ing.

FIG. 4 is a cross sectional view showing a second embodiment of the present invention.

Reference numeral 21 denotes a steel column, and 22 denotes a beam member. Further, G indicates a garage.

Conventionally, it has been customary to provide the reinforcing member 31 so as to close the entrance GT of the garage G, but the reinforcing member 23 is a unit structure (reference numeral omitted).
It is possible to effectively use the entrance / exit GT by fixing it to the one steel frame column 21 from around the outer periphery of.

The present invention is not limited to the above embodiments, but can be applied to various design changes made by those skilled in the art, for example, when a sleeve wall is provided on a terrace facing a garden. is there.

[0026]

As described above, according to the invention described in claim 1, in the case where a specific type steel material requires additional reinforcement, a unit structure is provided between the type steel material and the foundation. By fixing the type steel material requiring reinforcement and the foundation of the unit structure from around the outer periphery of the body with the reinforcing material, it is possible to prevent the reinforcing material from blocking the side surface of the structure. Therefore, there is an effect that the restriction on the building design due to the presence of the reinforcing material can be relaxed while the structure is reinforced.

According to the second aspect of the present invention, since the reinforcing material is fixed to the top level of the foundation of the unit structure, the construction of the foundation work can be simplified and its reinforcement can be ensured. The effect is that
