Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor structure of a corridor of a staircase provided in a multi-storey building such as a two-story and a three-story building.

[0002]

2. Description of the Related Art In a two-story building, a staircase is provided from the first floor to the second floor, and stairs are provided in the staircase. In recent years, the corridor on the upper floor of the staircase has been exposed to the outside like a terrace. However, if the corridor on the upper floor is exposed to the outside, rainwater may enter from the outside.Therefore, in order to drain the invading rainwater, a water gradient should be provided on the floor of the corridor to lower the outdoor side. Is being done. Then, when providing a water gradient on the floor of the conventional corridor, the water gradient is provided on the floor of the entire corridor.

[0003]

However, if a water gradient is provided on the floor of the entire corridor, a large number of floor materials to be laid in the corridor must be installed with water gradients, respectively. There is a problem that a large size or a step is generated, and there is a problem that the structure is complicated because it is necessary to make the whole frame structure for giving a slope to the floor material a slope structure.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a water gradient only to a floor material in a corridor close to the outdoors, thereby causing a large deviation of the floor material. It is intended to provide a floor structure of a corridor of a staircase of a building that can eliminate the risk of a large scale and can eliminate a large-scale sloping structure.

[0005]

In order to achieve the above object, the structure of the floor of the corridor of the staircase of the building of the present invention is such that a staircase 6 is provided in a proper place of a multi-storey building A so as to extend over a plurality of floors. The corridor 18 on the upper floor of the staircase 6 is exposed outside like a terrace,
Of the floor materials 24 of the corridor 18 on the upper floor, the floor material 2 on the side closer to the outdoors
4a is provided with a water gradient that decreases downward toward the outdoor side, and the floor material 24b other than the side closer to the outdoor side of the corridor 18 is horizontal.

[0006]

According to the above construction, the floor material 24a on the side closer to the outdoors
By providing a water gradient only on the floor and flattening the remaining floor material 24b, construction can be performed without causing a large deviation as in the case where a water gradient is provided on all floor materials as in the conventional case, and the frame structure There is no need for complex gradient structures throughout the body.

EXAMPLE The building A of this example is called a multi-story row house, and the dwelling unit 1 on the first floor and the dwelling unit 2 on the second floor are one as shown in FIGS. 2 (a), (b) and FIG. It is installed in one building A, but each is independent. Entrance 3 in the right place on the first floor
Is provided, and a pair of independent gates 4 are provided at the entrance 3, respectively.
5 is provided. That is, the gate 4 is a gate for the first floor, and the gate 5 is a gate for the second floor. Gatepost panels 11 having an appearance like a gatepost are erected on both sides of the entrance 3, and a pair of gates 4 and 5 are attached to the gatepost panel 11 by hinges so as to be openable and closable. A staircase 6 is provided so as to extend from the first floor to the second floor at a portion where the entrance 3 is located. Staircase 6
The first-floor portion 6a is partitioned by a partition wall 10a as a partition 10 as shown in FIG. 4, and a first-floor passage 7 and a second-floor passage 8 are formed. The gate 4 for the first floor of the entrance 3 and the passage 7 for the first floor communicate with each other, and by opening the gate 4, it is possible to enter and exit the passage 7 for the first floor. There is a front door 1 in the dwelling unit 1 on the first floor so that you can enter and exit from the passage 7 for the first floor.
3 is provided, and by opening the entrance door 13, it is possible to enter and exit the dwelling unit 1 on the first floor through the entrance on the first floor. The gate 5 of the entrance 3 and the second-floor passage 8 communicate with each other, and by opening the gate 5, it is possible to enter and exit the second-floor passage 8. The first-floor passage 7 and the second-floor passage 8 are separated by the partition wall 10a, so that an independent space cannot pass between them. At this time, the center between the pair of gates 4 and 5 and the street of the partition wall 10a as the partition 10 are combined to have a simple appearance.

A staircase 9 for raising and lowering is provided between the first floor portion 6a and the second floor portion 6b of the staircase 6. The stairs 9 are provided in a folded manner so as to have a substantially U shape when viewed from above, and a landing 14 is provided in the middle. The second floor portion 6b of the staircase 6 is as shown in FIG. 5, and a staircase sleeve wall 15 is provided on the floor of the second floor portion 6b so as to surround the staircase 9. Second-floor dwelling unit 2 so that you can enter and exit from the second-floor part 6b
An entrance door 16 is provided in the room, and by opening the entrance door 16, it is possible to enter and exit the dwelling unit 2 on the second floor via the entrance 17 on the second floor. The second floor portion 6b of the staircase 6 is a terrace-like corridor 18 exposed to the outside, and a handrail panel 20 is provided along the outer periphery of the corridor 18 so as to be flush with the outer wall panel 19 on the first floor. A handrail 21 is provided at the upper end of the handrail panel 20. A staircase storage 22 is provided below the stairs 9 in the first floor portion 6a of the staircase 6 using the space under the stairs 9, and the storage door 23 from the first floor passage 7 of the first floor portion 6a. It can be opened and closed for storage by the residents on the first floor. Further, since the second floor portion 6b has the terrace-like corridor 18, the front of the entrance of the dwelling unit 2 on the second floor can be widened. In addition, the entrance 3 has a sleeve wall 30 on the left side, and when viewed from the front of the entrance 3, the stairs 9 are not visible on the exterior due to the sleeve wall 30 and the gate post panel 11, so that the appearance can be a detached house.

Since the corridor 18 on the second floor, which is the upper floor, is exposed to the outside, there is a risk that rainwater may enter the interior, and the following measures have been taken to drain the rainwater that has penetrated into the interior. . A plurality of floor materials 24 are laid on the floor of the corridor 18, but only the floor material 24a close to the outdoors is provided with a water gradient so that it gradually decreases toward the outdoors, and the remaining floor materials 24b are horizontal. It has been laid. When a water gradient is applied to the outdoor floor material 24a, as shown in FIG. 1, the outdoor side beam 25 and the front beam 26 are erected with a floor support metal 27 at an angle, and the floor material is placed on this. 24a is installed and the floor material 24a is provided with a water gradient. A drain groove 28 is provided on the upper surface of the floor material 24a on the outdoor side, and rainwater discharged along the water gradient is collected in the drain groove 28 and drained in the drain groove 28. At this time, since the flooring materials 24b other than the flooring material 24a are laid horizontally, the flooring material 24 does not have a large displacement unlike the conventional one having a water gradient, and the entire frame structure has a complicated gradient structure. You don't have to.

FIG. 7 shows another embodiment. Horizontal beam 2
8, the floor material 24a and the floor material 24b are placed and constructed, the spacer 29 is attached to the upper surface of the beam 28 opposite to the outdoor side, and the end portion of the floor material 24a opposite to the outdoor side. Is placed on the spacer 29 to provide a floor material 24a with a water gradient, and the floor material 24b is placed on the spacer 29 to horizontally install the floor material 24b.

[0011]

As described above, according to the present invention, among the floor materials of the corridor on the upper floor, the floor material closer to the outdoor side is provided with a water gradient that decreases downward toward the outdoor side, and other than the side closer to the outdoor side of this corridor. Since the floor material is horizontal, it is possible to set a water gradient only in a place with a lot of rain and level a place with little rain. Since the construction is carried out in such a manner that it can be constructed without causing a large displacement or a step in the floor material, the construction can be simplified because it is not necessary to make the entire frame structure into a complicated gradient structure.
