Abstract

PURPOSE:To eliminate the difficulty of an under-floor construction by the heavy work by arranging floor joists at a prescribed interval between small beams, laying and attaching a lightweight flexible board having a prescribed thickness or less and fixing a floor finishing member. CONSTITUTION:Three floor joists 5 are installed in a small beam distance about 450mm or less on the small beams 4, and a sheet 8 made of polyethylene foamed body is laid and attached. A flexible board 6 which is in 12mm thickness X1383mm width X 895mm length and has a weight of about 31kg is laid on the sheet 8 and a spacer 9 for a ceiling beam 1' and fixed on the floor joist 5 by machine screws. Then, a throating 91 is installed between the flexible board 6 and a wall, and a trough 93 is installed between a handrail. Further, a floor finishing member 7 is laid on the flexible board 6 and the throating 91, and connected through adhesion, and an outer corridor floor is finished. Accordingly, the construction of a floor substrate can be executed in simple manner.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a floor structure for an exterior corridor of a building.

(Prior art) Conventionally, the floors of exterior hallways and second-floor porches were constructed by placing a subfloor material such as a floor support plate or extruded cement board on beams installed at both ends of the hallway, and Concrete was being poured.

For example, in Japanese Patent Application Laid-Open No. 1-102137, extruded cement boards are laid on beams provided at both ends of the porch,
The structure of the entrance porch on the second floor, with concrete poured on top of it, is described.

Furthermore, Japanese Patent Application Laid-Open No. 1-102135 describes a floor structure for a second-floor entrance porch in which floor support plates are laid on beams provided at both ends of the porch, and concrete is poured on top of the floor support plates. .

(Problem to be solved by the invention) However, floor support plates and extruded cement boards are heavy;
The work of laying this was difficult. Furthermore, it takes several days for the concrete poured on top of this to harden, creating the inconvenience of not being able to walk on this corridor during this time.

Therefore, the present invention provides a floor structure for an outside hallway that does not have the above-mentioned problems, that is, does not use a heavy flooring material that is difficult to work on, or does not use a material that takes time to harden, such as concrete. The purpose is to

(Means for Solving the Problems) The present invention is a floor structure for an outside hallway made to solve the above problems and achieve the above objects, in which the distance between the floor joists is 4.
Install a floor joist with a thickness of 50 mm or less, and install a
A flexible board with a thickness of 2 mm or less is laid down, and a floor finishing material is then laid on top of this.

(Function) In the present invention, a flexible board with a thickness of 12 mm or less is laid on the floor joists provided with a distance between the floor joists of 450 mm or less.

In this way, the floor joists are cool! Since the floor joists were installed with a thickness of 450 mm or less, even if the flexible board was used as a relatively thin floor base material with a thickness of 12 mm or less, it would be able to withstand the weight placed on top of the hallway.

Also, flexi boards with a thickness of 12 mm or less are usually vertical x
It is sold with a width of 910mm x 1820mm. Since the weight of this 12 mm thick flexi board is approximately 36 kg, two people can easily install it.

(Example) Hereinafter, an example in which the floor structure of an outside hallway of the present invention is applied to a floor structure of an outside hallway on the second floor (corridor width: 1505 mm) will be described with reference to the drawings.

In the figure, 1 is the ceiling beam on the first floor, on which the handrail of the hallway is installed.

1' are also the ceiling beams on the first floor, and these ceiling beams L L
'There are four small beams in between, and above this is the outside corridor.

This small beam 4 is slanted around 1 so that rainwater flows toward the handrail side.

Reference numeral 2 is also a ceiling beam on the first floor, and a floor beam 3 on the second floor is attached on top of this, and above it is a room on the second floor.

5 is a floor joist, and on top of the small beam 4, the distance between the small beams is 440 m.
There are three m.

A sheet 8 of polyethylene foam is adhered to the upper surface of this floor joist to improve the walking sensation.

9 is a spacer for adjusting the height of the ceiling beam 1' and the floor joist 5.

The thickness is 12 mm on the polyethylene foam sheet 8 and the spacer 9, and the length in the width direction under the IIL is 1383 mm.
A flexible board 6 with a length of 895 mm in the longitudinal direction of the hallway and a weight of 31 kg is laid and fixed to the floor joist 5 with screws.

91 is a drainer, which is a steel plate covered with a vinyl chloride resin sheet. 93 is a gutter, and 192 is provided above this.

A long vinyl chloride sheet 7, which is a floor finishing material, is adhered onto the flexible board 6 and the drainer 91.

Next, we will explain how to install the floor of the outside hallway.

A sheet 8 of polyethylene foam having a thickness of 2.5 mm is adhered onto the floor joist 5. A spacer 9 is glued onto the ceiling beam 1'. A flexible board 6 is laid on the sheet 8 and spacer 9 and fixed with screws.

Since the weight of the flexible board 6 is 31 kg, the laying work can be done by one person, or easily by two people.

Next, a drainer 91 is attached between the flexible board 6 and the wall, and a gutter 93 is attached between the flexible board 6 and the handrail.

An adhesive is applied on the flexible board 6 and the drainer 91, a floor finishing material 7 is laid down, this is glued, and a groove 192 is provided on the gutter 93, thereby completing the floor of the outside hallway.

(Effects of the Invention) In the present invention, since the interval between the floor joists is set to 450 mm or less, a relatively thin and lightweight flexible board with a thickness of 12 mm or less can be used as a floor base. Furthermore, simply laying this flexiboard creates a subfloor, making it easy to construct the subfloor.

Also, since the floor finishing material is provided on top of this flexiboard, the flexiboard will not wear out even if you walk on it, and therefore the asbestos contained in this flexiboard will not scatter. There is no damage caused by asbestos and it is safe.

Furthermore, since materials such as cement that require time to harden are not used during the construction of this floor, the construction can be completed in an extremely short time.
