Abstract

PURPOSE:To prevent the damage of components on the wooden building body side by a floor member effectively under the state of a quake, such as an earthquake, etc., when an inner balcony using the floor member made of a metal is constructed to a building in wood. CONSTITUTION:In a base material 12 constituting the approximately rectangular- shaped floor face of an inner balcony 10 and made of a metal, only the peripheral section of one side in the peripheral sections of three sides extended on the inside of a building is fixed to the member 102 for fixing of a wall 310, and the peripheral sections of other two sides are not fastened and supported movably to the placing members 18a, 18b of walls 320, 330a. Consequently, even when the building in wood conducts quake operation with strain, the placing members 18a, 16b perform sliding movement with the floor member 12, thus preventing possibility, in which the wooden side in a bonding section is damaged. Accordingly, the state of the installation of the inner balcony 10 in the building in wood is stabilized.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for an inner balcony, and more particularly to a mounting structure for an inner balcony, which is provided in a wooden building and has a floor formed of a metal member.

[0002]

2. Description of the Related Art In a reinforced concrete structure 500 such as a condominium, an inner balcony 520 shown in FIG. 4 is used which forms a balcony on the inner side of the outer wall line 510 of the building, that is, on the indoor side. There is. Also, such an inner balcony 520
Is used to prevent snow on balconies as much as possible in cold regions because it does not extend outward from the outer wall.

On the other hand, even in a wooden building, it is required to install an inner balcony in order to improve the appearance of the building or to meet the legal requirements for constructing an evacuation passage to the outside of the room in the building.

When installing an inner balcony in such a wooden building, in cold regions, it is necessary to consider an increase in the load of snow falling from the outside and corrosion of the structure due to melted water. .. Therefore, even if the other structures of the building are made of wood, the floor of the inner balcony is made of a metal member in order to ensure sufficient strength and water resistance to withstand the load. There is a need.

[0005]

As described above, in the case of forming an inner balcony in a wooden building, if the floor plate of the balcony is made of a metal member, the floor plate of the balcony and other The problem arises from the fact that the material is completely different from the building structure.

For example, when a vibration applied to a building, particularly an earthquake or the like, is applied, the floor plate portion made of metal of the inner balcony and the structure body on the building body side made of wood are formed. Different movements occur between them. Since the proof strengths are greatly different from each other, there is a problem that the wooden body of the building body is likely to be damaged when the entire outer edge portion of the floor plate is fixed to the building body side. ..

The present invention has been made to solve the above-mentioned problems, and its object is to damage a structure on the main body side of a building by vibration even if a floor plate made of metal is installed. It is to provide an inner balcony mounting structure without.

[0008]

[Means for Solving the Problem] A substantially rectangular floor surface is extended from the outer wall line of a wooden building toward the inside of the building,
In the inner balcony formed by surrounding the three side surfaces of the floor surface with walls, the floor plate portion forming the substantially rectangular floor surface is formed of a metal member, and the wall of the three side surfaces receives the floor plate portion. Each of the parts is provided, and one of the outer edges of the three sides of the floor plate extending inward of the building is fixed to the one receiving part, and the other two sides are movable to the remaining receiving parts. It is characterized by being supported.

[0009]

According to the inner balcony mounting structure having the above structure, since the floor plate portion of the inner balcony is formed of a metal member, the floor portion is bent or damaged even under a load caused by snow. In addition, it has good corrosion resistance to rainwater and snow.

Further, in the metal floor board portion, only one outer edge portion of the three outer edge portions extending inside the outer wall line of the building is fixed to the wall-side receiving portion, and the other two. The side is movably supported by the receiving portion on the wall side. Therefore,
When the whole building vibrates due to an earthquake, etc., the metal floorboard can shake along with the fixed building structure on one side, and the other two sides can vibrate separately from the building structure. To be done. Therefore, based on the different materials of metal and wood, both components perform different shaking motions, but two of the three sides allow different shaking motions in a non-fixed state. There is no risk of damaging the structural side of the timber with which the wooden floor member comes into contact.

In particular, since the receiving portions for supporting the floor member of the inner balcony are independently provided on the three walls, in case of a shaking motion such as an earthquake, the three walls of the three walls have different shaking motions. Even if it becomes, each receiving part operates individually according to the wall surface, so unlike the case where the receiving part is an integral rigid member, it effectively prevents damage to the joint part with the structure of the wood can do.

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a schematic perspective view showing a mounting structure of an inner balcony according to an embodiment of the present invention, in particular, a mounting state of a metal floor plate portion.

In the figure, the building-side structure 100 is cut inward in a substantially U-shape from the building outer wall 200 located on the outermost outer wall of the building in order to construct an inner balcony. This U-shaped space is a wall 310 having a window 301 on the back side, and walls 320, 33 on both sides thereof.
It is in a state surrounded by 0s.

The inner balcony 10 is constructed in the U-shaped space. Unlike the building structure 100 made of wood, the inner balcony 10 is made of a metal member, for example, an iron member. That is, it is made of a metal having high strength so as not to be bent or damaged when there is snow in a cold region. Further, unlike wood, it also has good water resistance, so that it can effectively prevent corrosion and the like.

FIG. 1 shows a base member 12 which is a basic member for constructing the floor plate portion of the inner balcony 10, and a feature lies in the mounting and fixing structure of the base member 12.

That is, the base material 12 has a planar shape corresponding to the substantially rectangular shape of the floor surface of the balcony, and only one of the three sides of the portion extending to the inner side of the building outer wall 200 is formed. It is characterized in that the outer edge portion is fixed to the building structure 100.

In this embodiment, the base material 12 is fixed to the wall 310 of the building structure 100 only on one side on the back surface side. This fixing is performed between the fixing standing portion 12a attached to the back side of the base material 12 and the fixing member 102 as a receiving portion attached to the wall 310. That is, through holes 14 and 104 are formed in the fixing upright portion 12a and the fixing member 102 at corresponding positions, respectively, and the bolts 16 and the like are passed through the through holes 14 and 104 to fasten them. is there. The bolt 16 is screwed in from the indoor side of the building and is tightened with a nut or the like on the side of the fixing standing portion 12a.

On the other hand, the outer edges of the other two sides of the base material 12 are movably supported by the building structure 100 without being fixed to the building structure 100.

In this embodiment, it is slidably mounted on the mounting members 18a and 18b fixed to the walls 320 and 330 on both sides.

Elongated ridges 20a and 20b protruding in an arc shape are formed on the upper surfaces of the mounting members 18a and 18b, respectively. On the other hand, groove portions 22a and 22 that are long arcuate concave portions are provided at corresponding locations on the bottom surface of the base material 12.
b is formed. That is, with the fixing upright portion 12a side fixed to the fixing member 102, the groove portions 22a and 22b of the base material 12 are configured to engage with the ridges 20a and 20b.

FIG. 2 is a structural explanatory view of the floor member of the inner balcony 10 having the base material 12 as a basic structure. The plate-like flat plate 26 capable of penetrating downward is installed.

On the upper surface of the base material 12, there are formed a plurality of receiving core materials 28 formed in correspondence with the inclination of the bottom surface of the waterproof pan 24, and the waterproof water is inclined so that the drain hole 24a is located at the lowest position. The bread 24 is supported from below. As a result, the thawed water flows through the waterproof pan 24 and flows down from the drain hole 24 to a gutter (not shown).

The specific operation of the embodiment having the above configuration will be described with reference to FIG.

For example, when the whole building is shaken in the direction of arrow 300 in the figure due to an earthquake or the like, the base material 12
(The same applies to the waterproof pan 24 and the slatted flat plate 26 attached thereto) is fixed to the building structure 100 on the back side thereof, and thus similarly swings in the direction of the arrow 300.

On the other hand, the two outer edges of both sides of the base material 12 are not fixed to the building structure 100 but are simply placed, so that the base material 1 slides in the direction of arrow 300.
There is no possibility that the building structure 100 side will be damaged by the movement caused by the shaking of 2. That is, since the wooden building shakes while causing various distortions, even if the structural parts 100a and 100b on both sides of the base material 12 sway with a different movement from the structural part 100c on the back side of the base material 12, the base material 12
Since the mounting members 18a and 18b can slide with respect to each other, damage to the portions of the mounting members 18a and 18b can be effectively prevented.

Further, the mountain portions 20 of the mounting members 18a and 18b
Since the a and 20b extend in the direction of the arrow 300, the groove portions 22a and 22b of the base material 12 have the peak portions 20a and 20b.
It slides along b.

Further, even when the base material 12 shakes together with the structural portion 100c, the mounting member 18 of the structural portions 100a and 100b also shakes in the direction of the arrow 400 in the figure.
Sliding movement is performed between a and 18b. Therefore, damage to the building structure 100 side can be similarly prevented. In this case, since the mount members 18a and 18b have the ridges 20a and 20b engaged with the grooves 22a and 22b of the base member 12, a force sufficient to cause a shake but damage to the base member 12 until a certain small shake. The engaging state is disengaged before being applied, and the mounting portion slides in the same manner as described above.

As described above, according to this embodiment, compared to the conventional case where all three sides of the base material 12 are fixed,
Damage to the building structure 100 side due to the movement of the base material 12 can be effectively prevented.

The present invention is not limited to the above embodiments, but various modifications can be made within the scope of the invention.

For example, although the back side of the base material 12 is fixed in the above embodiment, the present invention is not limited to this, and one side of both sides of the base material 12 may be fixed.

Further, the base material 12 and the mounting members 18a, 1
The support structure with 8b is not limited to the above-mentioned example, but may be a structure in which a long hole formed on one side and a pin protruding from the other side are engaged with each other.

[0033]

As described above, according to the mounting structure of the inner balcony of the present invention, even when the inner balcony using the metal floor member is mounted on the wooden building, the metal structure is It is possible to effectively prevent damage to the timber structure side due to the difference in proof strength with timber. As a result, it is possible to improve the reliability of the construction of the inner balcony on the wooden structure.

Further, since the balcony floor plate is made of metal, it can withstand a load during snowfall.
