DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underfloor partition member and a method for laying the partition member under a floor.

In recent years, as a floor structure of a building, as shown in FIG. 1, a formwork 1 formed by drawing a sheet of polyvinyl chloride resin is placed on a concrete slab 2 and the formwork 1 is placed on the formwork 1. A gypsum-based leveling material 3 is cast and cured to form an integrated flooring material.

The mold 1 has substantially funnel-shaped support legs 4 and has a cross section formed by connecting a large number of arches. Is formed.

[0004] By casting the leveling material 3 thereon, a solid and integrated smooth floor is formed on the formwork 1, and the leveling material 3 fills the support legs 4. Is done.

The floor is supported on the slab by the leveling material 3 in the support legs 4 to support the load, and a space 5 between the support legs 4 extends vertically and horizontally below the floor, and various cables are provided there. And pipes can be laid.

In recent years, it has been attempted to use the space 5 below the form 1 for air conditioning on such a floor. That is, air is blown into the space 5 below the floor from an air conditioner installed at an appropriate place, and warm air is blown out from a blow hole formed at an appropriate place on the floor surface to heat the room. It is.

When air conditioning is to be performed as described above, it is necessary to provide a partition in the space 5 below the formwork 1.

That is, it is not rare that an integrated floor is formed in a large room, and the room is divided into a large number of rooms by appropriately dividing the room with partitions. Thus, it is necessary to provide a partition in the empty space 5 and individually air-condition those rooms.

FIG. 2 shows such a room, in which a partition 6 is provided in a cross shape below the floor of a large room to divide the room into four sections. And air conditioner 7 for each section
Is provided, and warm air is sent from the air conditioner 7 to the vacant space 5 in one section.

[0010] A hot air outlet 8 and a slit-type outlet 9 are formed on the floor surface, and the warm air sent into the space 5 enters the room through the outlets 8 and 9. Blowing
They heat each section.

In FIG. 2, reference numeral 10 denotes an inspection port opened on the floor. Reference numeral 11 denotes an electric cable laid under the floor through the space 5, and reference numeral 12 denotes an outlet installed under the floor, which is capable of receiving power by inserting a plug from above the floor.

In another case where a partition is required, warm air is blown into the empty space 5 from an air conditioner provided at a specific location so that the warm air is evenly distributed throughout the room. For this reason, it may be preferable to appropriately provide a partition in the space 5 to form a hot air passage.

[0013]

2. Description of the Related Art In the case where a partition is provided in the space 5 under the floor as described above, conventionally, when a floor is constructed, a bar material such as styrofoam is installed at a lower portion of the formwork 1 according to a predetermined arrangement. It was used as a partition.

[0014]

However, in such a partition, if the partition of the room is to be changed or the route of the hot air is to be changed in the future, the styrofoam bar which has already been installed is removed or the position is changed. Cannot be changed, and it is almost impossible to install a new partition.

The present invention has been made in view of such circumstances, and it is easy to provide a new partition or remove an existing partition as necessary after constructing a floor having the above structure. Partitioning material that can be used for
It is intended to provide a method of laying the same.

[0016]

According to the method of laying a partition of the present invention, a mold having substantially funnel-shaped support legs and having a space extending vertically and horizontally below the support legs is mounted on a slab. In a method of laying a partition along the void, on a floor formed by placing a leveling material on the formwork, a flexible rod-shaped sponge is inserted into a flexible tubular body having airtightness. The partition member is used as a partition member, and the volume of the partition member is reduced by depressurizing the inside of the cylindrical body, and the partition member is arranged along a predetermined space along the space of the floor, and then the pressure is released and the partition is released. It is characterized by restoring the volume of the material.

The partition member of the present invention is characterized in that a flexible rod-shaped sponge is inserted into a flexible tubular body having airtightness.

In the partition member, it is preferable to use, as the tubular body, a flexible tubular cloth having a flexible airtight lining made of rubber or synthetic resin on the inner surface thereof.

Another partitioning member of the present invention is a member in which a flexible rod-shaped sponge is inserted into an airtight flexible rubber or synthetic resin tube, and the outside thereof is covered with a tubular cloth.

[0020]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 3 shows a state in which the partition member 13 of the present invention is laid in the space 5, and the partition member 13 is almost the height of the space 5 from the upper surface of the slab 2. The flow of warm air in the left-right direction is blocked.

FIG. 4 shows a partition member 13 of the present invention. Reference numeral 14 denotes a flexible sponge rod such as urethane foam. The sponge rod 14 is inserted into a tube 15 as a flexible airtight cylindrical body such as urethane rubber, and further has a flexible outside. Cylindrical fabric 16 is covered.

The tubular fabric 16 has strength in the longitudinal direction and has a certain degree of abrasion resistance. A tubular woven fabric formed by weaving a warp and a weft in a tubular shape is used. Is preferred.

The distal end of the tube 15 is sealed, and a loop 17 for pulling is provided at the distal end of the tubular fabric 16. The rear ends of the tube 15 and the tubular fabric 16 are open.

In this partition member 13, the tubular fabric 16
Although it is not necessary, a considerable load is applied when the partition member 13 is drawn into the space 5 below the floor, and the partition member 13 receives friction between the concrete slab 2 and the formwork 1. It is preferable to cover with the fabric 16.

Further, as the tubular body, a tubular fabric in which the inner surface of the tubular fabric is provided with an airtight lining and the tubular fabric 16 and the tube 15 are integrated may be used.

The sectional shape of the partition member 13 of the present invention is not particularly limited, and may be any shape such as a square, a rectangle, and a circle. Preferably, the size of the cross section is such that when laid in the space 5, the space 5 is filled as shown in FIG. 3, and the height of the sponge 14 is equal to the height of the space 5. Or a slightly larger one is suitable.

[0027]

The method of laying the partition 13 under the floor will be described, and the operation of the partition 13 of the present invention will be described.

First, a towing line is inserted along the space 5 according to the path on which the partition member 13 is to be laid using the inspection port 10 on the floor surface, and one end of the towing line is connected to a loop at the tip of the partition member 13. 17 is connected.

Next, at the rear end of the partition member 13, the tube 15 is connected to the tip of the pressure reducing device, and the pressure inside the tube 15 is reduced. As the decompression device, a home vacuum cleaner can be used.

When the pressure in the tube 15 is reduced, the tube 1
5 wither, and the sponge 14 in the tube 15 is also compressed, reducing its volume.

In this state, the towing line is towed, and the partition member 13 is pulled in according to the path through which the towing line is inserted. At this time, since the volume of the partition member 13 is reduced, there is no large resistance and the partition member 13 can be pulled in with a small force. Also, even if there are various cables and pipes in the route, they can be easily pulled in across them.

When the partition member 13 is pulled into a predetermined position, the pressure reducing device is removed to release the reduced pressure in the tube 15. As a result, the sponge 14 expands, and the tube 15 and the tubular fabric 16 also expand due to the expansion force.
3 is restored to its original volume and is filled to 5 voids.

Also, when removing the existing partition member 13, the tube 15 is pulled out in a state where the volume is reduced by reducing the pressure inside the tube 15, so that the crossed cables and the like are not damaged with a small force. Can be pulled out.

Further, since the volume of the partitioning material 13 of the present invention is reduced by reducing the pressure, the partitioning material 13 can be pushed into the space 5 from the inspection opening 10. Can also be laid.

[0035]

According to the present invention, therefore, a partition for blocking warm air can be easily laid in a closed space under a floor, and the position of an existing partition can be easily changed. Therefore, it is possible to easily cope with a change in the layout of a room or a correction of a hot air path.

In the above description, the technology for using the space under the floor for heating is described. However, the present invention can be used for cooling by passing cool air through the space. Is valid.
