Description

Detailed Description of the Invention [Industrial applications]

The present invention relates to a structure for forming a corridor between a pair of adjacent two buildings.

[Prior art]

Even if there are two buildings structurally, if they are connected to each other, they may be regarded as inseparable buildings according to the law and treated as one building, and it is possible to receive advantageous treatment in various aspects. . For this reason, for example, in a collective dwelling formed by providing a plurality of dwelling rooms, a common corridor may be separately installed between two adjacent buildings. in this case,
Structurally, the common corridor was constructed so that a corridor pillar dedicated to the corridor was erected separately in the gap between two adjacent buildings to support the load. The common hallway was then used to enter and leave each living room in both buildings. However, since there are corridor pillars in the gap between the two buildings, the corridor pillars are an obstacle, and the effective width of the corridor formed between the two buildings is narrowed by the corridor pillars. There is a problem of becoming. Therefore, as a construction method in which the present inventor does not need to provide such a corridor column, the frame of the corridor base is fixed to the beams of the outer walls of the two buildings facing each other and the load of the corridor is received by the beams of the building. Thought of doing so.

[Problems to be Solved by the Invention]

However, when the corridor base materials are fixed to the beams on the outer walls of a pair of opposing buildings as described above, the pair of buildings are treated as one building, but each building is structurally completely mutual. Because of the independence, when the above-mentioned pair of buildings shakes due to an earthquake or the like, the pair of buildings will shake in different states independently of each other, and shear stress etc. will act on the frame that is the base of the corridor. Then, there is a problem that a mounting portion of the frame to the beam is damaged or cracks are generated in the mortar or the like for finishing the corridor. Therefore, in order to solve such a problem, a corridor is projected in a cantilever manner from the outer walls of a pair of buildings facing each other, and the tip of the corridor is close to the outer wall of the other building. I thought about cutting the structure structurally, but in this case,
All the loads in the entire corridor are applied to the outer wall side of one building, and therefore the structural materials such as beams on the outer wall side of the building supporting the load of the entire corridor do not apply to the other corridor. There is a problem that a member having a large supporting force is required as compared with a structural material such as a beam on the outer wall side, and the members cannot be shared. The present invention has been made in view of the above problems, and its purpose is to support the load of the corridor by the structural material of the outer wall of the building on both sides without requiring a special corridor pillar, In addition, the structure of the corridor that connects two buildings is provided so that there is no risk of damage to the outer wall of the building that is the framework of the corridor, or cracks in the finished mortar, etc. It is in.

[Means for Solving the Problems]

The structure of the corridor connecting the two buildings according to the present invention is constructed by projecting the corridor halves 3 in a cantilever shape from the outer wall 2 of the two parallel independent structures 1 of the corridor halves. The side ends are brought close to each other to face each other, and the connecting plate 4 is installed between the opposite side ends of the adjacent corridor halves 3 so as to be slidably coupled to at least one of the corridor halves 3. The above-mentioned object of the present invention is achieved by adopting such a configuration.

[Action]

According to the present invention, there are two parallel independent buildings 1
The corridor halves 3 project in a cantilever shape from the outer walls 2 of the corridor halves, and the side ends of the corridor halves 3 are brought close to each other, and at least one connecting plate 4 arranged between the corridor halves 3 is provided. By being slidably attached to the corridor half body 3, even if the two buildings 1 facing each other independently shake and the shear stress acts on each corridor half body 3, this shear stress is applied to the connecting plate 4 It is absorbed by the slide. The corridor formed between the two buildings 1 projects from the outer wall 2 of the two independent buildings 1 in a cantilever shape to the corridor halves 3 and the side ends of the corridor halves 3 respectively. Since they are configured to be close to each other and face each other, the loads of the corridor halves 3 projecting like cantilever beams are similarly supported by the structural materials of the outer wall 2 portion of each building 1, The structural materials of both buildings 1 will be shared.

【Example】

Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings. Two independent buildings 1 are constructed in parallel, and as a pair of these buildings 1, there are multiple living rooms.
An example of an apartment house formed by providing 1a is shown. The corridor halves 3 project in a cantilever shape from the opposing outer walls 2 of the pair of buildings 1 and the side ends of the corridor halves 3 are brought close to each other and face each other. To project the corridor halves 3 from the opposing outer walls 2 of the building 1 on both sides, for example, as shown in FIG. In FIG. 2, the beams 5 on the opposite outer wall 2 sides of the pair of constructs 1 facing each other are made of, for example, H-shaped steel, and are installed between columns of the outer wall 2. The upper and lower horizontal pieces of a U-shaped short connecting fitting 6 are fixed to the beam 5. The connecting metal fitting 6 faces the part of the outer wall 2 that is open, and the side surface of the connecting metal fitting 6 is located substantially flush with the outer surface of the outer wall 2. In this case, the connecting metal fitting 6 is connected to a part of the outer wall 2. The side surface of the metal fitting 6 may be covered with a curtain plate made of a metal plate to waterproof the connecting metal fitting 6 portion with the curtain plate.
A frame 7 serving as a base of the corridor half body 3 is attached to the side surface of the connection fitting 6 with a bolt 8. The frame 7, which is the base of the corridor half body 3, is constructed by constructing a cantilever 7c between a receiving beam 7a and a front beam 7b. In this way, the frameworks 7 serving as the bases of the corridor half bodies 3 are projecting from the outer walls 2 of the two independent buildings 1 in a cantilevered manner. The connecting plate 4 is installed by being installed between the opposite end portions of the skeleton 7 which is formed. In this case, the connecting plate 4 is slidable to the skeleton 7 side which is the base of at least one of the corridor halves 3. Is to be combined. The connection plate 4 is formed of a metal plate or the like,
Inclined pieces 21 are provided on both side edges, and large-diameter holes 22 are formed in both side ends of the connecting plate 4 at positions closer to the inner side than the inclined pieces 21. This connecting plate 4 is used to connect the frames 7 of the corridor halves 3 projecting from each building 1. When connecting, first, the front beam 7b of the skeleton 7 of the one corridor half 3 is fitted with the receiving member 23. Is attached by welding or the like, and the receiving member 23 is attached by welding or the like to the front beam 7b of the frame 7 of the other corridor half body 3. The receiving member 23 is made of steel having a U-shaped cross section, and the upper piece 2
4 is provided with a screw hole 25. Then, as shown in FIG. 2, the connecting plate 4 is laid over both receiving members 23,
As shown in the drawing, the bolt 26 passed through the large diameter hole 22 of the connecting plate 4 is screwed into the screw hole 25 of the receiving member 23. At this time, the large-diameter hole 22 is formed as a round hole having a diameter much larger (several times or more) than the diameter of the bolt 26, and a holding plate 27 having a larger diameter than the large-diameter hole 22 is inserted into the bolt 26. Bolts 26 and screw holes 25
When it is screwed in, the pressing plate 27 is pressed against the upper surface of the connecting plate 4 at the peripheral edge of the large diameter hole 22. Therefore, the connecting plate 4 can be slid in the horizontal plane within a range in which the bolt 26 can move in the large diameter hole 22. As described above, the connecting plate 3 can be fixed to the frame 7 of each corridor half body 3 via the receiving member 23, and the frame 7 of each corridor half body 3 can be connected by the connecting plate 4. After the frames 7 are connected by the connection plates 4 in this manner, the floor of the corridor half body 3 is formed in each frame 7. That is, in the embodiment shown in the accompanying drawings, the deck plate 9 is placed on the skeleton 7, the lightweight concrete 10 is placed thereon, and the mortar 11 is finished to form the floor of the corridor half body 3. By doing so, the corridor halves 3 projecting cantileveredly from the outer walls 2 of the pair of opposing buildings 1 are formed, and the corridor halves 3 facing each other are connected by the connecting plate 4. It forms a common corridor between the two buildings 1. The stairs 40 are connected to this corridor, and the stairs 40 are the pillars 4 for stairs.
1 is erected and fixed to this, and the above-mentioned connecting plate that is structurally cut off from each corridor half body 3 and used to connect the corridor half bodies 3 to each other. 4 is slidably connected. By the way, from the common corridor, it is possible to go in and out of each of the living rooms 1a provided in the two buildings 1 facing each other. In FIG. 2, 31 is a corridor ceiling attached to the lower surface of the corridor half body 3, 32 is a connecting ceiling that connects the corridor ceilings 31 of each corridor half body 3, and the connecting ceiling 32 slides with respect to each corridor ceiling 31. It is preferable to connect them freely. Further, rock wool 34 is provided on the lower side of each corridor half body 3 and on the opposite side of the corridor half body 3.
To improve the fire resistance. By connecting the corridor halves 3 projecting in a cantilever manner from the outer wall 2 of the facing building 1 with the connecting plate 4, the pair of building 1 can be treated as one building. is there. And although it is treated as one building under the law, each building 1 is structurally completely independent of each other, so when the building 1 shakes due to an earthquake or the like,
Although the building 1 swings in different states independently of each other, the coupling plate 4 can slide and move as described above, so that the displacement stress between the coupling plate 4 and the corridor half body 3, etc. Even if the contact plate acts, this displacement stress is absorbed by the sliding movement of the connecting plate 4, the connecting portion between the connecting plate 4 and the corridor half body 3 is damaged, and the connecting plate 4
It is possible to prevent the damage. Further, the common corridor formed between the two buildings 1 is structurally divided into two corridor halves 3, and each corridor half 3 is a structurally independent building. 1
Since it is fixed in a cantilever shape, the load from each corridor half body 3 is supported by the beam 5, which is the structure of the outer wall 2 of each building 1. Therefore, the beams 5 supporting the corridor halves 3 of the outer wall 2 of each building 1 can use members having the same strength, and the members can be shared. In addition, in the above-mentioned embodiment, when the connection plate 4 is installed between the opposite side end portions of the adjacent corridor halves 3 and attached, both ends of the connection plate 4 are slidably attached to both corridor halves 3. However, one end of the connecting plate 4 may be fixed to one corridor half 3 and the other end of the connecting plate 4 may be slidably coupled to the other corridor half 3.

【The invention's effect】

As described above, in the present invention, the corridor halves are projected in a cantilever shape from the outer walls of the two independent independent buildings in parallel, and the side ends of the corridor halves are brought close to each other to face each other, Connecting plates are installed between the opposite ends of adjacent corridor halves, and the connecting plates are slidably connected to at least one of the corridor halves, so the two buildings facing each other are independent. Even if it shakes and shear stress acts on each corridor half, this shear stress is absorbed by the slides of the connecting plates, and the part of the corridor foundation frame attached to the outer wall of the building is damaged or finished. There is no risk of cracks in the mortar, etc., and the corridor formed between the two buildings is a cantilever half-shaped corridor from the outer wall of the two independent buildings. Projecting sideways of the corridor half Since they are configured to face each other closely, the loads of the corridor halves projecting like cantilever beams will be similarly supported by the structural material of the outer wall of each building, The structural materials are standardized.
