Abstract

PROBLEM TO BE SOLVED: To perform the new construction of the floor face of a building and repair work at low cost and in a short time by aligning protrusions of approximately truncated cone shape at specified spaces on one face of foundation material, and laying the foundation material on an existing floor in the state of the protrusions pointing to the existing floor so as to form utility space between the foundation material and the existing floor. SOLUTION: Foundation material with protrusions 10 of approximately truncated cone shape aligned with specified spaces on one face is laid on an existing floor 12, in the state of the protrusions 10 pointing to the existing floor 12 so as to form utility space for a drain passage or the like between the foundation material and the existing floor 12. Manual work such as tiling is therefore dispensed with, and the most part of the lower side of the foundation material is made the space for the drain passage or the like excluding the protrusions 10. The new construction of the floor face of a building and repair work can thereby be performed at low cost and in a short time, and convenience of drainage and the like is improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foundation material to be overlaid on, for example, an existing floor, and in particular, it is cheaper to newly install or repair a floor surface of an underpass, an outdoor floor surface, or a floor surface of a building such as an OA floor. The present invention relates to a basic material which can be performed in a short time, and can further enhance the convenience such as drainage of a road surface such as an underground passage, a floor surface, etc. by a use space formed inside.

For example, an underground space is further expanded in front of a station in a city, and a large number of people pass along the road surface such as the underpass.

[0003]

2. Description of the Related Art Here, for example, when a subway is newly provided, it is necessary to first form a foundation surface, then flatten the upper surface with concrete, and finally cover the concrete surface with tiles. .

Further, a drainage channel is provided along the underpass so that the water flowing out on the underpass is flowed to the drainage channel.

[0005]

However, for example, when a subway or the like is newly constructed, since the work of covering the subway with tiles or the like is performed, a large amount of cost is required for this and a long time is spent.

[0006] Further, when the work of reattaching tiles and the like is performed, the cost and time are similarly required.

When the rainfall is heavy, the rainwater is likely to concentrate in the underground space, and in some cases, the drainage channel becomes inoperable and the underground passage is flooded. This often happens even when water leaks.

The present invention has been made in view of the above-mentioned conventional circumstances, and an object thereof is to perform new construction or repair work on a road surface of an underpass, an outdoor floor surface or a floor surface of a building such as an OA floor. An object of the present invention is to provide a base material that is inexpensive and can be performed in a short time, and that is extremely convenient in terms of drainage and the like.

[0009]

In FIG. 1, the foundation material is such that projections 10 having a substantially truncated cone shape are aligned on one surface at a predetermined interval, and the projections 10 are directed to the existing floor 12 in the existing floor. A space for use (drainage channel) is formed between the existing floor 12 and the existing floor 12.

In FIG. 1, the base material is such that projections 10 having a substantially truncated cone shape are arranged on one surface at predetermined intervals, and the projections 10
Is laid on the existing floor 12 in a posture in which the water is directed to the existing floor 12, and a utilization space (drainage channel) is formed between the existing floor 12 and the drainage hole 14 from the other surface to the drainage channel. It is provided at a position avoiding the protrusion 10.

In FIG. 1, the base material is such that projections 10 each having a substantially truncated cone shape are arranged on one surface at predetermined intervals, and the projections 10 are formed.
Is laid on the existing floor 12 in a posture of directing to the existing floor 12 to form a use space (drainage channel) between the existing floor 12 and the drainage channel from the other surface to the drainage channel. 14
Are provided at positions avoiding the protrusions 10.

(Operation) When a road surface of an underpass, an outdoor floor surface, or a floor surface of an OA floor is newly constructed, first a foundation surface is formed, and then the upper surface is flattened with concrete or the like,
The foundation material is simply laid on this existing floor 12 (concrete floor).

Then, the base materials are densely arranged in the longitudinal direction of the surface of the underpass or the like, and when the width of the underpass or the like is wide, the base materials are densely arranged in the direction crossing the underpass.

Therefore, it is not necessary to perform manual work such as attaching tiles, so that an underpass or the like can be newly constructed more efficiently at low cost in a short time.

By simply laying the foundation material on the existing floor 12,
A space such as a drainage channel is formed between the existing floor 12 and
Since most of the lower side of the base material is a space such as a drainage channel except for the protrusions 10, the drainage performance and other convenience are significantly improved.

Therefore, when the drainage channel is used, even if rainwater concentrates underground when it is raining or leaking water, it is effectively prevented that the underpass is flooded and unusable.

Further, since the projection 10 is formed into a substantially truncated cone, the thickness and interval of the projection 10 can be set appropriately, or the entire foundation material for the underpass can be made of concrete, so that it is strong and durable. It becomes possible to form an excellent underpass.

Furthermore, when reconstructing a structure such as an existing underpass, an outdoor floor surface, an OA floor, etc., when tiles have already been applied to the structures, the existing tiles need to be re-executed without redoing the operation. It is sufficient to simply lay the foundation material on the surface.

Since the drain hole 14 is provided at a position avoiding the protrusions 10, the drainage holes 14 are efficiently drained to the lower side of the foundation material, and no water pool is formed on the road surface such as an underground passage.

Since the hole 14 for draining water (for drainage) is a long hole, drainage is further enhanced.

Moreover, if this long hole is used as a hook hole for lifting at the time of new construction or repair of the road surface of an underpass, the outdoor floor surface or the floor surface of the OA floor, the work can be performed more easily and efficiently. Is possible.

EXAMPLE FIG. 1 is a perspective view showing an example of the present invention, in which the base material of this example is made of concrete containing glass fibers to improve its strength and reduce its weight. Is intended.

FIG. 2 illustrates a vertical cross section of this embodiment, and projections 10 are arranged on the lower surface of the projection 10 at predetermined intervals.

FIG. 3 shows this embodiment turned upside down. As can be understood from this drawing and FIG. 2, each projection 10 is in the shape of a truncated cone, and the peripheral side surface is rounded in the hem direction and cut off. The area is gradually increasing.

Therefore, by setting the thicknesses and intervals of the projections 10 to appropriate values, a road surface of an underpass, an outdoor floor surface or an OA-floor surface which is resistant to compression and has excellent durability is formed. .

Further, as understood from FIGS. 2 and 3, a large number of drain holes 14 are provided at positions avoiding the protrusions 10.

These drain holes 14 are elongated holes as shown in FIG. 4, and penetrate the base material of this embodiment vertically.

The base material is laid on the existing floor 12 in a posture in which the projections 10 are directed to the existing floor 12 as shown in FIG.

The laying work is carried out by hooking the water draining hole 14 which is a long hole with a metal fitting and lifting it.

As can be seen from FIG. 5, the foundation material of this embodiment is densely arranged in the longitudinal direction of the floor surface of the underground passage and in the direction crossing the floor surface and covers the upper surface of the existing floor 12.

It is preferable to use a heavy machine for hoisting the foundation material. If a heavy machine is used, the laying work can be saved and can be performed efficiently. The plate material of this embodiment can sufficiently withstand the weight of heavy machinery and running.

When the laying of the base material is completed, a drainage tunnel (utilization space) is formed between the existing floor 12 and the existing floor 12 and runs vertically and horizontally under the base material.

The existing floor 12 is a concrete floor whose base surface is flattened when a floor surface such as an underpass is newly constructed.

When repairing an existing underpass, etc.,
It is said to be a tile surface attached on a concrete floor.

The base material of this embodiment is configured as described above, and its operation will be described in detail below.

In the case of newly constructing a floor surface such as an underpass, a foundation surface is first formed, then the foundation upper surface is flattened with concrete, and the foundation material of this embodiment is simply placed on the concrete floor 12.

The laying work of the base material is carried out by hooking the elongated holes 14 with metal fittings and hoisting them with a heavy machine, and arranging the base materials densely in the longitudinal direction of the underpass or the direction crossing the underpass as shown in FIG. Done.

That is, the manual work of tile application is omitted, so that the construction cost of the floor surface of the underpass is remarkably reduced, and the construction period is also remarkably shortened.

When the existing floor surface such as an existing underpass is to be repaired, the base material of this embodiment is laid on the tile road surface in the same manner as when the new building is installed.

Therefore, even when the existing floor surface of the existing underground passage is reworked, the construction cost of the floor surface of the underground passage is remarkably reduced and the construction period is also remarkably shortened.

The base material of the present embodiment is made of concrete, each protrusion 10 has a truncated cone shape, and the peripheral side surface thereof is rounded toward the hem direction, and the cross-sectional area gradually increases. The example base material can withstand the weight and running of heavy equipment.

Further, since the base material of this embodiment is made of concrete containing glass fibers and is lightweight, it is possible to perform the laying work by hand without using a heavy machine.

Here, when the foundation material is laid on the existing floor 12, a utilization space such as a drainage channel is formed between the foundation material and the existing floor 12 (see FIG. 6), and the lower portion of the foundation material forms the projection 10 portion. Except for the drainage channel, all of the space will be used space, so the convenience of drainage of the underpass will be extremely good.

Therefore, even when rainwater is concentrated under the ground and is flooded by an underground passage at the time of heavy rain or water leakage, the surface of the underground passage is not submerged, and therefore, the passage can be carried out in the same manner as usual.

Further, since the projection 10 is formed into a substantially truncated cone and the plate material is made of concrete, the floor surface such as an underpass has excellent durability and can be used as it is for a long period of time.

Further, since the drain hole 14 is provided at a position avoiding the projections 10, the water is drained as it is to the lower side of the foundation material without accumulating on the road surface such as an underground passage. No water splashes will occur during passage.

Moreover, since the drainage (drainage) hole 14 is a long hole, the drainage performance of the underpass is extremely convenient.

In the use space (drainage tunnel) formed with the existing floor 12, gas, water and sewer pipes, electricity, and telephone wiring can be installed. In this example, the foundation material of the present invention is placed on the back instead of the existing floor,
That is, the protrusion 10 may be placed on the upper side, and the base material may be placed on the protrusion 10 so as to be placed thereon.

In this case, the use space becomes wider.

As described above, according to the present embodiment, the substantially circular truncated cone projections 10 are arranged on one surface at a predetermined interval, and the projections 10 are oriented toward the existing floor 12 so that the existing floor 1 can be positioned.
Since the utilization space (drainage channel) is formed between the existing floor 12 and the second floor, and the long hole 14 for draining water from the other surface to the drainage channel is provided at a position avoiding the protrusion 10. Reduce the cost required for new construction and repair work on the floor surface of structures such as underpasses, outdoor floors or OA floors,
Also, the construction period can be shortened and the drainage convenience of the underpass can be improved.

Since the base material is made of concrete, the durability of the underpass and the like is enhanced, and the construction period can be greatly shortened by using a heavy machine.

[0052]

As described above, according to the present invention, the projections of the substantially truncated cone are arranged on one surface at a predetermined interval,
Since the projection is directed to the existing floor, it is laid on the existing floor and the space used (drainage channel) is formed between it and the existing floor.
By eliminating the need for manual work such as tiling, it is possible to reduce the cost required for underpass construction, shorten the construction period, and improve the convenience of drainage of underpasses.

Further, since the drain hole 14 which penetrates the foundation material and reaches the drainage channel is provided at a position avoiding the projection 10, the water is not drained on the road surface of the underpass and is drained to the lower side of the foundation as it is. Therefore, water splashes do not occur during passage of the underpass.

Since the long hole 14 is provided for draining water, the drainage of the foundation is further improved, and by using this as a hook hole, the work of laying the plate material can be efficiently performed. .
