Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Application on B) The present invention relates to a floating floor structure and its construction method, and in particular,
This relates to measures to improve construction efficiency.

(Prior art) Conventionally, in mid-rise to high-rise housing, cushioning materials made of glass wool or the like have been placed on the subfloor made of concrete floor slabs, etc., in order to prevent floor impact noise from being transmitted to the lower floors! A floating floor structure has been implemented in which floor panels are placed in parallel on the cushioning material. This floating floor structure has the effect that floor impact force is absorbed by the cushioning material and transmission of impact noise to the downstairs is reduced.

On the other hand, in such a floating floor structure, border joists are placed on the subfloor surface to stably support the floor near the walls and all around the interior of the room, and the floor panels of the indecent floor are placed directly on the joists. A floor surface is formed by placing or connecting them with rigid connecting materials.

(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 laying the above-mentioned cushioning material and before installing the floor panels, when workers pass through the guide 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, requiring care when transporting materials, requiring time and effort, and creating a risk of injury. There was a problem of damage caused by compression.

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 these points, and by making it possible to use the supporting material of the floor panel as a work scaffold during construction, it facilitates material handling and improves construction efficiency. The purpose is to prevent damage to the cushioning material.

(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.

In addition, the measures taken by the second invention are as follows: - As a construction method for the F2 floating floor structure, first, a floor of a predetermined width with supporting legs is placed on a subfloor made of a concrete floor slab or the like in at least one part of the room. Placed on the side. Thereafter, a cushioning material such as a glass wool mat is laid on the subfloor on the center side of the room, and then a floor panel is placed on top of the m art materials 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, work 877 is reduced to walking 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 quickly and easily perform construction, increasing construction efficiency. It is possible to improve the In addition, the above-mentioned gentle V
Since there is no walking on the fJ material, damage to the cushioning material can be prevented, and since the above-mentioned floor serves as a support material for the floor panel, a work scaffold can be secured without increasing the number of materials. Can be done.

Furthermore, since the above-mentioned floor is placed on the side of the room, furniture etc. can be stably installed, but it is not possible to place furniture etc. in the center of the room where floor impact forces are likely to occur. ! Since the floor panel is arranged through the shock absorbing material, the transmission of the 1i7 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 residential building, 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 floating floor 2 and a floating floor 3 are arranged on the floor base 11 of the indoor room 1, and the floating floor 2 is placed along the wall 12 of the indoor room 1.
It is located on the western side of the city, that is, on the entire periphery. The storage floor 2 is a storage floor panel in which support legs 22 22 made of bolts or the like extending downward are protruded from the four corners of the lower surface of a plurality of rectangular base plates 21 formed in a flat plate shape. 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 thereon. Further, elastic members 23, 23 made of rubber, springs, etc. are attached to the lower end surfaces of each of the support legs 22, 22, and the elastic members 23 reduce the transmission of impact force to the flooring 11. . By adjusting the height of the supporting legs 22 and 22, the upper surface of the floor 2 and the upper surface of the floating floor 3 are set to be at the same level as the road surface.

On the other hand, the above-mentioned floating floor 3 has an indoor area 1 surrounded by the standing floor 2.
The side surface of the floating floor 3 is placed in close proximity to the center side surface of the room 1 of the neck floor 2, and a cushioning material made of glass wool, rock wool mat, foamed synthetic resin, etc. is placed on the floor base 11. 31 is laid, and a large number of floor panels 32.32. . . . are arranged directly or in parallel via a gap maintaining material such as a joist.

Furthermore, the floor panels 32, 32 . . . . A finishing material 5 such as a wooden floor material is placed above the upper surface of the floor 2 on both sides via a thin joist material 4, and the finishing material 5 is appropriately fixed by nailing. Floor panel 32 of the above floating floor 3
．． 32. ...is supported.

Next, a construction method for the above-mentioned floating floor NII structure will be explained.

First, after constructing the floor base 11 and walls 12 made of concrete floor slabs, etc., an elastic material 2 is placed on the lower end surface of the support leg 22.
3 is attached to the floor 2 is placed around the entire periphery of the room 1.

After that, a buffer U is placed in the center of the room surrounded by the above-mentioned floor 2.
31 is laid on the floor base 11, and then floor panels 32, 32 . ... in parallel. Then, the floor panel 32.32°...The joist material 4 is placed on top.
After placing the finishing materials 5, the finishing materials 5 are fixed by nailing to complete construction of the floating floor structure.

Therefore, since the floor 2 is provided with a predetermined width that allows walking and is once stable, it is necessary to install the floor after the cushioning material 31 is laid and before the floor panel 32 is laid. Since workers and the like can walk on the storage floor 2 to transport materials, construction work can be carried out without walking on the cushioning material 31 that sinks. 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, thereby improving construction efficiency. And the above-mentioned cushioning material 31
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 for carrying in and storing the floor panels 32 and cushioning materials 31, so materials are not scattered on the floor. Therefore, 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.

Further, it is possible to concentrate wiring and arrangement of rooms around the periphery of the room 1 by utilizing the spaces between the plurality of support legs 22 on the lower surface of the floor 2.

Furthermore, since the stable floor 2 is placed around the periphery of the room 1, furniture etc. can be stably installed, while the central part of the room 1 where floor impact forces are likely to occur, that is, freedom of human movement. Since the large portion is configured as a floating floor 3 as in the conventional case, transmission of impact sound 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.

FIGS. 3 and 4 show another embodiment, in which instead of the previous embodiment in which the storage floor 2 is arranged around the entire periphery of the room 1,
A storage floor 2 is arranged on three sides of an indoor room 1. Furthermore, 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, construction workers who are in J3 at construction site 1 can walk stably by using the floorboards 2 on the three sides.

In each of the above embodiments, the floor 2 is provided on the entire periphery or on three sides of the room 1, but it may be placed on two or one side depending on the size and purpose of the room 1 and the position of the window. It may also be provided only in

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.

Alternatively, the finishing material may be one in which plywood or the like is discarded and pasted over the entire surface of the floor panel 32 on which the wooden floor is constructed with joists, and then a carpet is applied.

In addition, 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 and 22 of the floor 2 may be fixed to the bottom of the floor base 11 with screws or the like.

(Effect of the invention in Sung Dynasty) As described above, according to the floating floor structure and the construction method of the present invention, since the floor with a predetermined width is provided on at least one side of the room, it is possible to , workers can walk on a stable floor, so there is no need to worry about instability! ! Since there is no need to walk on damping materials and stability can be ensured when walking, there is no risk of injury, construction can be carried out quickly and easily, and construction efficiency can be improved. . Furthermore, since the user does not walk on the il box 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.
