Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a floating floor structure and its construction method, and particularly to measures for improving construction efficiency.

(Prior art) Conventionally, in mid-rise to high-rise housing, in order to prevent floor impact noise from being transmitted to the lower floors, cushioning materials made of glass wool or the like are laid on the subfloor made of concrete floor slabs, etc. Floating floor structures are being constructed in which floor panels are placed side by side on top of cushioning material. This floating floor structure has the effect that the impact force of the floor is absorbed by the cushioning material, thereby reducing the transmission of impact noise to the downstairs.

On the other hand, in such a floating floor structure, edge joists are placed on the subfloor to stably support the floor around the walls and other parts of the room, and the floor panels of the floating floor are placed directly on the joists. Alternatively, a floor surface is formed by connecting them with a rigid connecting material.

(Problem to be Solved by the Invention) In the above-mentioned floating floor structure, the cushioning material is formed with narrow joists and laid over almost the entire interior of the room, reducing the transmission of impact sound throughout almost the entire interior of the room. That's what I do.

By the way, during construction, after the above-mentioned cushioning material has been laid and before the floor panels are installed, when workers pass through the room to transport materials, they have to hold the floor panels because there is no work scaffolding. The user will walk on the cushioning material in a relaxed state. In this case, the cushioning material sinks, resulting in poor walking stability. Care must be taken when transporting materials, construction time is required, and there is a risk of injury. There was a problem with compression loss.

Furthermore, when furniture is installed near a wall, there is a problem in that the floor near the wall sinks due to the compression of the cushioning material, making the furniture less stable.

The present invention has been made in view of the above points, and
The purpose is to make it easier to transport materials, improve construction efficiency, and prevent damage to the cushioning material by allowing the floor panel support material to double as work scaffolding during construction. .

(Means for Solving the Problems) In order to achieve the above object, in the present invention, a floor with a predetermined width having supporting legs on the side parts of the room such as near a wall is placed on the subfloor, and The periphery is stabilized and a floating floor is formed inside.

Specifically, the means taken by the first invention is that, as a floating floor structure, a floor of a predetermined width having supporting legs is disposed on at least one side of the room on a subfloor made of a concrete floor slab or the like. At the center of the room of the floor, a floor panel is provided on the underfloor surface with a cushioning material made of glass wool or the like interposed therebetween.

Further, the measures taken by the second invention include, as a construction method of the above-mentioned floating floor structure, first, a floor of a predetermined width having supporting legs is placed on a subfloor made of a concrete floor slab or the like on at least one side of the room. to be placed. After that, a cushioning material made of glass wool mat or the like is laid on the subfloor on the center side of the room,
Next, a floor panel is placed on the cushioning material to construct a floating floor.

(Function) With the above configuration, in the present invention, a stable floor is placed on the side of the room, so during construction, workers etc. must walk on the floor to transport materials, etc. .

Therefore, workers do not have to walk on unstable cushioning materials and can walk safely, reducing the risk of injury, etc., and can perform construction quickly and easily. Efficiency can be improved. In addition, since there is no need to walk on the cushioning material, damage to the cushioning material can be prevented, and since the above-mentioned floor serves as a support material for the floor panel, work scaffolding can be used without increasing the number of materials. can be secured.

Furthermore, since the above-mentioned floor is placed on the side of the room, furniture etc. can be stably installed, while the floor panels can be placed with cushioning material in the center of the room where floor impact forces are likely to occur. Because of this arrangement, transmission of impact sound can be reliably reduced.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

As shown in FIGS. 1 and 2, 1 is a room in a medium-rise or high-rise residence, and a wall 12 made of a concrete slab or the like is erected continuously from a subfloor 11 made of a concrete floor slab or the like. It is formed.

A floor 2 and a floating floor 3 are arranged on the floor base 11 of the room 1, and the floor 2 is placed along the wall 12 on the four sides of the room 1, that is, on the entire periphery. It is arranged. The placing floor 2 includes support legs 2 made of bolts or the like extending downward at the four corners of the lower surface of a plurality of rectangular base plates 21 formed in a flat plate shape.
It is formed by installing a floor panel with projecting portions 2 and 22, and the base plate portion 21 of the floor panel is formed to have a predetermined width so that a worker or the like can easily walk on it. Furthermore, each of the support legs 2
Elastic members 23, 23 made of rubber, springs, etc. are attached to the lower end surfaces of 2, 22.
This reduces the transmission of impact force to the subfloor 11. In addition, the upper surface of the above-mentioned floor 2 is the support leg 2.
By adjusting the heights 2 and 22, the upper surface of the placing floor 2 and the upper surface of the floating floor 3 are made substantially flush with each other.

On the other hand, the floating floor 3 is disposed in the center of the room 1 surrounded by the floor 2, with the side surface of the floating floor 3 being close to the side surface of the floor 2 on the center side of the room 1, and the floating floor 3 is placed on the floor base 11. A cushioning material 31 made of glass wool, rock wool mat, foamed synthetic resin, etc. is laid on the cushioning material 31, and a large number of floor panels 32, 32, . They are arranged in parallel with each other.

Furthermore, a finishing material 5 such as a wooden floor material is placed on top of the floor panels 32, 32, . . . through a thin joist material 4.
are disposed over the upper surface of the floor 2 on both sides, and the finishing material 5 is appropriately fixed by nailing to support the floor panels 32, 32, . . . of the floating floor 3.

Next, a method of constructing the above-mentioned floating floor structure will be explained.

First, after constructing a floor base 11 and walls 12 made of concrete floor slabs, etc., a floor 2 with elastic members 23 attached to the lower end surfaces of supporting legs 22 is placed around the entire periphery of the room 1.

After that, a cushioning material 31 is laid on the floor base 11 in the center of the room surrounded by the above-mentioned floor 2, and then,
A large number of floor panels 32, 32, . . . are placed in parallel on the buffer material 31. And the floor panels 32, 3
2. After arranging the joist material 4 on top, the finishing material 5 is fixed by nailing to complete the construction of the floating floor structure.

Therefore, since a stable floor 2 with a predetermined width that allows walking is provided, during construction,
After the cushioning material 31 is laid down and before the floor panel 32 is laid down, workers can walk on the floor 2 to transport materials, etc.
Construction can be carried out without walking on the sinking cushioning material 31. Therefore, workers can walk around the room 1 with peace of mind, there is no risk of injury, and construction can be carried out quickly and easily.
It is possible to improve construction efficiency. Since the cushioning material 31 is not walked on, damage to the cushioning material 31 can be prevented. In addition, until the floating floor 3 is formed, the storage floor 2 serves as a support when the floor panels 32 and cushioning materials 31 are carried in and stored, so materials are not scattered on the floor. , it does not interfere with the installation work of equipment such as underfloor piping, and it is possible to improve work efficiency at the construction site. In addition, a plurality of support legs 22 on the lower surface of the floor 2
Wiring and piping can be arranged in a concentrated manner around the periphery of the room 1 by utilizing the space between the two spaces.

Furthermore, since the stable floor 2 is arranged around the periphery of the room 1, furniture etc. can be stably installed, while the central part of the room 1 where floor impact force is likely to occur,
In other words, since the part where there is a large degree of freedom in human movement is configured as a floating floor 3 as in the conventional case, transmission of impact noise can be reliably reduced.

In short, by providing the floor 2 that also serves as support for the floor panel 32, it is possible to improve construction efficiency without impairing the reduction of impact noise and without increasing the number of materials.

3 and 4 show other embodiments,
In place of the previous embodiment in which the floor 2 was arranged around the entire periphery of the room 1, the floor 2 was arranged at three sides of the room 1. On the other side of the room 1, a narrow joist 6 serving as a border joist is placed on the floor base 11 via an elastic material 7.

Therefore, during construction, workers and the like can walk stably by using the floorboards 2 on the three sides.

In addition, in each of the above embodiments, the storage floor 2 is indoors 1.
It was installed on the entire periphery or three sides of the room, but only one indoor
Depending on the size and purpose of the window and the position of the window, the window may be provided on two sides or only on one side.
In other words, when there are windows on two sides and doors on the other side, the furniture installation section is often limited to the remaining side; Good too.

In addition to the above-mentioned wooden floor joist construction, the finishing material may be one in which plywood or the like is pasted over the entire surface of the floor panel 32 and then a carpet is constructed.

Further, the supporting legs of the above-mentioned floor 2 may be rod-shaped with bolts, etc., or block-shaped with elastic material 23, and the height can be adjusted at the site by adjusting the thickness of the elastic material. It may be adjusted by changing.

Further, the lower ends of the support legs 22, 22 of the floor 2 may be fixed onto the floor base 11 with screws or the like.

(Effects of the Invention) As described above, according to the floating floor structure and its construction method of the present invention, since a floor of a predetermined width is provided on at least one side of the room, during construction, Since workers can walk on a stable floor, they do not have to walk on unstable cushioning materials, and the stability of walking can be ensured.There is no risk of injury, etc., and the work can be done quickly. Moreover, construction can be easily performed, and construction efficiency can be improved. Furthermore, since the user does not walk on the cushioning material, damage to the cushioning material can be prevented. Moreover, since the above-mentioned floor becomes a supporting material for the floor panel after construction is completed, a work scaffold can be secured without increasing the number of materials.

Furthermore, since the above-mentioned floor is placed on the side of the room, furniture etc. can be stably installed, while floor panels are placed with cushioning material in the center of the room where floor impact forces are likely to occur. This makes it possible to reliably reduce the transmission of impact noise.
