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 balcony in a building such as a house, and more particularly to a floor structure capable of a dry method.

[0002]

2. Description of the Related Art Conventionally, a floor structure shown in FIG. 5 is employed in a cantilever (take-out type) balcony of a steel-framed house. That is, a water gradient is provided with a mortar 52 on the upper surface of a floor base material 51 made of an ALC plate or the like, a waterproof sheet 53 is attached thereon, and a floor finish material 54 such as a balcony mat is further provided thereon. Reference numeral 55 denotes a building outer wall, and reference numeral 56 denotes a waist-shaped balcony outer wall.

[0003]

However, in this structure, since the mortar 52 is cast on site, there is a problem that it takes days to dry and the construction period of the building becomes longer.

[0004] Therefore, a dry method is desired, but the floor of the balcony needs to be drained and waterproof, and these measures are difficult. For example, when a floor is laid by simply providing a joist on the floor base material 51, it is necessary to perform a reliable waterproofing treatment at a joint between the floorboards, and the waterproofing treatment is difficult. Since the floorboards undergo thermal expansion and contraction, it is difficult to waterproof the seams between the floorboards.

[0005] It is an object of the present invention to provide a balcony floor structure in which the construction period can be shortened by a dry method and the drainage and waterproofness can be obtained with a simple structure.

[0006]

According to the present invention, a balcony floor structure according to the present invention is provided with a plurality of upwardly-grooved joists serving also as gutters in a vertical and horizontal lattice-like framed state, and these vertical and horizontal gutters are connected to each other. They are connected at the joints of each other. Each gutter joist forms a groove bottom deeper in the order in which these gutters continue, and connects a vertical gutter to the deepest gutter on the groove bottom. A plurality of floorboards are laid out vertically and horizontally so that the surrounding sides are placed on the vertical and horizontal gutters. Between adjacent floor edges, Ru a gap above the trough joists. In addition, the above-mentioned
Folded pieces for draining fall down at the end to be the joint
And at the bottom of the waist wall-shaped balcony outer wall,
Drainage with a lower end in the gutter along the balcony outer wall
A mounting plate is provided.

[0007]

According to this structure, the gap between the floor boards serves as a water outlet, and the rainwater on the floor board enters the gutter through the gap and flows through the gutter. This eliminates the need for waterproofing between floorboards. The gap between the floor boards also serves as a play portion for thermal expansion and contraction of the floor boards.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. FIG. 2 is a perspective view of a completed construction of the cantilever balcony. The floorboard 1 is made of a painted or coated metal plate or a resin plate, and a large number of the floorboards are laid out vertically and horizontally. The upper and lower surfaces of the floor panel 1 are provided with a decorative uneven portion 1a which also serves as a non-slip, so that a floor finishing material is not required. Instead of providing the uneven portion 1a, a floor finishing material such as a balcony mat may be laid. Draining plates 3 and 4 are attached to the lower part of the waist wall-shaped balcony outer wall 2.

FIG. 1 shows a state in which the floor plate 1 is removed. As a frame for supporting the floor panel 1, horizontal gutters 5A and 5C, each of which is a gutter also serving as a gutter, and a vertical gutter joist 5 are used.
B is provided in a framework state. Hiota 5A-5C,
Each is made of upward-facing lip channel steel, and the groove bottom surface is 5A, 5
B and 5C are formed deeper in this order. Lateral gutter 5
The end of A opens in the vertical gutter 5B, and the end of the gutter 5B opens in the horizontal gutter 5C. A vertical gutter (not shown) is connected to the deepest gutter 5C, and its connection port is covered with a roof drain 6 (FIG. 3) for dust removal.

The lower end of the drainer 4 is inserted into the gutter 5C and the gutter 5B at the end. As a result, the rainwater that has passed along the outer wall 2 is discharged from the gutters 5B, 5B.
C dropped. The gutter 5B is supported by a water gradient adjusting component 7 which also serves as a joist support at a plurality of locations in the longitudinal direction, and a water gradient is formed. It should be noted that the other gutters 5A and 5C may form a water gradient with a water gradient adjusting component having the same configuration as the water gradient adjusting component 7.

As shown in cross sections in FIGS. 3 and 4, a water gradient adjusting member 7 is a groove-shaped receiving member 8 which is fitted to the gutter 5B.
And a plate-like spacer 9 laminated in the receiving member 8, and the height of the water gradient is secured by adjusting the number of overlapping spacers 9. The receiving tool 8 is provided on a floor base material 10 on a floor plate 11.
It is installed through. Each spacer 9 may be simply stacked in a free state, or may be fixed to the receiving member 8 with an adhesive, a hole-in anchor, or the like.

The lower gutter 5C is installed on the floor base material 10 via a floor plate 11, and the upper gutter 5A is installed on the floor base material 10 via a joist receiver (not shown). The floor base material 10 is made of an ALC board or an extruded cement board or the like, and is installed on a floor beam 12. Flooring material 10
May be constituted by a wooden floor panel or the like, and the floor beam 12 may be omitted.

The floor panel 1 is provided with a heat insulating material 13 (FIG. 4) for preventing dew condensation on the back surface, and the edges of the four sides are each gutter 5.
A, 5B, and 5C. At the edge of each side of the floorboard 1, a bent piece 1b that enters the gutter 5A, 5B, 5C is provided, and a slight gap 14 is provided between the adjacent floorboards 1, 1.

A waterproof packing 17 is laid on the receiving surface of the floor panel 1 of the gutter joists 5A, 5B, 5C, and a waterproof packing 18 is also provided on the mutual connection part of the gutter joists 5A, 5B, 5C. It is. At the ends of the gutters 5A, 5B, which are interconnecting portions of the gutters 5A, 5B, 5C, bent pieces 19, 20 for draining are provided, respectively.

According to this configuration, the water on the floorboard 1 enters the gutter joists 5A and 5B from the gaps 14 between the adjacent floorboards 1, flows from these gutter joists 5A and 5B to the gutter joist 5C, and flows into the downspout (shown in FIG. 1). )). For this reason, drainage can be performed well,
In addition, the waterproof treatment at the seam of the floorboards 1 and 1 becomes unnecessary. The gap 14 between the floorboards 1 also serves as play against thermal expansion and contraction of the floorboards 1. In addition, since each of the gutters 5A, 5B, and 5C serves both as a gutter and a joist, a dedicated gutter is provided on the floor plate 1.
There is no need to provide it on the back side, and the structure is simple.

At the time of construction, gutters 5A, 5B, 5C
It is only necessary to install the floor panel 1 after the framework, and the entire balcony floor can be constructed by the dry method. Therefore, there is no need to provide a drying period, and the construction period is shortened.

[0017] The Contact, gutter joists 5A, 5B, 5C is not limited to the lip groove-shaped, may be a conventional channel-shaped, or may be a groove shape or the like of the slits provided on the upper surface of the round pipe.

[0018]

According to the floor structure of the balcony of the present invention, a gutter made of a channel material and serving also as a gutter is provided in a vertical and horizontal grid-like frame state, and on the gutter joist between edges of the floor plate. Since the gap is provided, the rainwater on the floor plate enters the gutter from the gap and flows through the gutter. For this reason, drainage can be performed well,
In addition, the waterproofing treatment at the seam of the floorboards becomes unnecessary, and therefore, the entire balcony floor can be constructed by the dry method, thereby shortening the construction period. Moreover, since the joists also serve as gutters, there is no need to provide dedicated gutters, and the structure is simple.
