Description

Description: TECHNICAL FIELD The present invention relates to a water leakage recovery device for recovering water leakage such as rainwater and groundwater that have entered a room in a concrete building.

[Prior Art] Conventionally, in concrete buildings, there are many accidents in which water leaks such as rainwater and groundwater enter a room from, for example, a cracked portion of concrete and damage electric equipment and the like installed in the room.

Therefore, for example, Japanese Patent Application Laid-Open No. 52-25416 and Japanese Utility Model Application No. 50-11521.
As disclosed in No. 2 (Japanese Utility Model Publication No. 52-28914), a technique is disclosed in which a waterproof plate is suspended and fixed to a ceiling structure to receive water leaking from the ceiling structure.

However, these are techniques for receiving water leakage by a waterproof plate that is suspended and fixed to a ceiling structure, and there is no disclosure regarding the subsequent handling of water leakage.

Further, Japanese Patent Application Laid-Open No. 53-41017 discloses a technique of collecting water from the ceiling with a gutter and discharging it from a drain pipe.

However, the one disclosed in Japanese Patent Laid-Open No. 53-41017 is one in which water on an arch-shaped ceiling member is sent to a drain pipe gutter which is laid horizontally on a wall surface for treatment.

Therefore, it is effective when it is placed in an extremely small room such as a cooking room described in the example of the specification of the publication, but it is large when a large number of beams and columns exist like a concrete building. It is not suitable for rooms with spaces, and it is difficult to deal with water leakage from cracks formed in many beams and columns themselves.

[Problems to be Solved by the Invention] The present invention has been made in view of the above problems, and is an optimum water leakage recovery apparatus for a room having a large space where a large number of beams and columns exist, such as a concrete building. It is intended to provide.

[Configuration of the Invention] The present invention provides a waterproof plate suspended from the lower surface of a ceiling structure in a state where an edge of the beam is close to the beam, and a gutter for a beam disposed along the lower edge of the beam. The pillar comprises a rotating gutter which is arranged below the edge of the gutter for the beam and has a drainage pipe, and leaks water collected by the waterproof plate into the trough for the girder. It is characterized in that the leakage water collected by the tub is arranged so as to flow down to the tub.

[Operation] Leakage water dripping from the ceiling structure is received by the waterproof plate suspended from the lower surface of the ceiling structure and dropped from its edge to the beam gutter arranged along the lower edge of the beam.

Water leaking from the beam itself is also dropped on the beam gutters arranged along the lower edge of the beam.

Leakage that has fallen into the beam gutter is made to flow down to the swirling gutter that is wound around the column and drained from the drain pipe.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings.

The drawing shows the girders 2A, 2B, 2C continuous with the pillar 1 and the girder 2A,
It is an example of the case where the present invention is applied to a concrete ceiling structure 4 divided by a beam 3 continuous to either 2B or 2C.
A waterproof plate 5 is suspended from the lower portion divided by 2A, 2B, 2C and the beam 3 with almost no gap.

It is preferable that the waterproof plate 5 be inclined toward one of the beams located in the surroundings rather than being horizontal, and in this embodiment, the waterproof plate 5 is hung and arranged so that the beam 3 side is inclined downward. ing.

The waterproof plate 5 is suspended by, for example, a suspension member 7 fixed to an insert 6 fixed to the lower surface of the ceiling structure 4.

Each edge of the waterproof board 5 is brought close to the large beams 2A, 2B, 2C and the small beam 3, respectively.

Further, beam gutters 8A, 8B, 8C and 9 are arranged along the lower edges of the large beams 2A, 2B and 2C and the small beam 3, respectively.

These beam gutters 8A, 8B, 8C and 9 are each made of a long waterproof material, and one of them can be used, for example, as in the case of the beam gutter 9 arranged on the beam 3 shown in FIG. The bent portion 91 formed at the end edge is inserted and locked into the insert rail 10 formed in the center of the lower surface of the beam 3 in the longitudinal direction, and the bent portion 92 formed at the other end edge. Is supported by a plurality of L-shaped brackets 11 arranged on the side surface 31 of the beam 3 at appropriate intervals in the longitudinal direction.

In particular, this embodiment has a configuration in which the projection 12 formed at the tip of each bracket 11 is fitted into a plurality of through holes 93 formed in the bent portion 92 with a predetermined interval, and a special tool is used. The beam gutter 9 can be attached to the beam 3 very easily without using it.

In addition, a swirl gutter 13 is wound around the columns 1 below the longitudinal edge positions of the beam gutters 8A, 8B, 8C and 9.

The gutter 13 is formed of a plate material having waterproofness like the gutters 8A, 8B, 8C and 9 for beams, and a drainage pipe 15 is connected to the outlet 14.

The lower end of the drainage pipe 15 is connected to, for example, a drainage port (not shown) provided on the floor or the like.

In the drawings, reference numeral 16 is a water leakage detector such as a water leakage detection mesh arranged on the upper surface of the waterproof plate 5, reference numeral 17 is a water leakage detector arranged in the turning gutter 13, and reference numerals 18 and 19 are water leakage detectors. 1
It is a connection cord for transmitting an electric signal from 6 and 17 to a leak alarm device (not shown).

In the present embodiment having the above-described configuration, the water leaking from the cracks or the like formed in the ceiling structure 4 is received by the waterproof plate 5 hung on the lower surface of the ceiling structure 4, and its edge and the girder 2A are received. , 2B, 2C and girders 3, or from the edges to the girders 2A, 2B, 2C and girders 3 through the girders 2A, 2
Beam gutters 8 along the lower edges of B, 2C and beam 3.
Fall into A, 8B, 8C and 9.

At this time, in this embodiment, since the waterproof plate 5 is inclined so as to be lowered toward the beam 3, most of the leaked water falls into the beam gutter 9.

Further, not only the ceiling structure 4 but also water leaks from cracks formed in the large beams 2A, 2B, 2C and the small beams 3 themselves, the gutters 8A, 8B, 8C for beams arranged along the lower edge of each beam and It falls to 9.

Then, the water leakage from the ceiling structure 4 and the girders 2A, 2B, 2C and the girders 3 dropped on the beam gutters 8A, 8B, 8C and 9 is directly from their edges or other gutters 8A, Through 8B or the like, it is flowed down to the swirl gutter 13 which is wound around the pillar 1, and is drained through a drain pipe 15.

In particular, in this embodiment, for example, since the water leak detectors 16 and 17 are arranged on the upper surface of the waterproof plate 5 and the main points such as the gutter 13, it is possible to immediately check the occurrence of water leak and the point of occurrence. Therefore, it is possible to take immediate action.

Although only the portion of the ceiling structure 4 which is divided by the girders 2A, 2B, 2C and the girders 3 has been described, the present invention is applied to the entire concrete ceiling structure 4 in the same manner. Water leakage can be completely prevented.

In addition, drainage treatment is also possible for water leaks from cracks formed in the upper columns of the column around gutter 13.

[Advantages of the Invention] The present invention has a waterproof plate hung on the lower surface of a ceiling structure in a state in which the edge is brought close to the beam, and a gutter for a beam arranged along the lower edge of the beam. It has a structure consisting of a rotating gutter which is wound below the edge of the beam gutter of the column and has a drainage pipe, and has a large number of beams and columns like a concrete building. It is possible to reliably handle water leakage from ceiling structures and beams and columns in a room with space.

In addition, since water leakage is treated continuously from the drainage pipe of the surrounding gutter that is wound around the pillar, it can be used permanently, requires no special maintenance work, and has a complicated configuration. It is also easy to install and economically advantageous.

Furthermore, a small installation space is sufficient, and there is no fear of the room becoming narrow.
