(Hereinafter, the interlocking teeth 22 and 42 will be referred to as connecting interlocking teeth). That is, a fastener 35 (hereinafter referred to as a connection fastener) including tapes 22T, 42T, connection teeth 22, 42, and a slider 46 is configured between the liquid receiving sheet 20 and the support sheet 30.

On the other hand, the coupling teeth 44 provided on the side facing the connecting coupling teeth 42 of the strip sheet 30A mesh with the coupling teeth 44 provided on the strip sheet 30B, and move the pair of sliders 48 provided on the strip sheet 30A. As a result, the belt-shaped sheets 30A and 30B are integrated, and the mounting fastener 40 allows the support sheet 30 to be opened and closed along the center line (hereinafter, the fastening teeth 44 will be referred to as mounting fastening teeth). Note that a slider 48 may be provided on each of the belt-shaped sheets 30A and 30B. Further, the support sheet 30 located at the outermost position when the plurality of liquid receiving sheets 20 are arranged may be provided with the coupling teeth 42 only on one side.

The length of the connecting teeth 42 of the support sheet 30 corresponds to the length of the connecting teeth 22 of the liquid receiving sheet 20, that is, the longitudinal length L of the liquid receiving sheet 20. . On the other hand, the length of the mounting teeth 44 of the support sheet 30 is longer than the length of the connecting teeth 42 over the longitudinal length L1 of the support sheet 30.

When water leakage occurs in the ceiling due to rain leakage, the liquid receiving device 10 is carried in parts to the space between the ceiling and the upper floor or track bed (or similar space), and is placed in the attic. will be installed.

FIG. 2 is a schematic perspective view of the liquid receiver when installed in the attic. FIG. 3 is a diagram showing the connection relationship between the parts of the liquid receiver as seen from the side of the hanging bolt. Here, two liquid receiving sheets 20 and three supporting sheets 30 are used.

In the attic spaces of buildings such as buildings and station buildings, the field edge receiving material 130, which is a base material, is structurally installed in line with the back surface of the ceiling C, and the field edge 100 intersects on the field edge receiving material 130. installed along the direction. The field edges 100 are regularly arranged at predetermined intervals along the direction in which the field edge receiving material 130 extends.

A hanging bolt 120 suspended from the upper foundation is connected to the field edge 100 via a hanger 110. The hanging bolts 120 are lined up in accordance with the installation location of the field edge 100, and are regularly arranged at predetermined intervals along the direction in which the field edge 100 extends.

In this embodiment, the width W of the liquid receiving sheet 20 along the transverse direction is set to a length corresponding to the distance L2 between the hanging bolts 120 adjacent to each other along the field edge 100, and the liquid receiving apparatus 10 The length is determined so that it will bend downward when it is installed. On the other hand, the length L along the longitudinal direction of the liquid receiving sheet 20 is twice the distance interval L3 between the adjacent hanging bolts 120 along the field edge receiving material 130, that is, the distance interval between the three adjacent hanging bolts 120. The length is set accordingly.

The liquid receiving sheet 20 is installed in an inclined manner so that one end thereof is higher than the other end. As a result, the leaked water dripping onto the liquid receiving sheet 20 flows toward the center of the sheet and toward the lower position. A drain fitting 65 attached to the tip side of the hose 60 is attached to the lower side of the liquid receiving sheet 20, and leakage water flowing to the lower side of the liquid receiving sheet 20 flows into the hose 60 through the drain fitting 65 and is extracted. be done.

Below, a procedure for installing the liquid receiving device 10 in the attic will be explained.

The operator folds up the liquid receiving sheet 20 and the support sheet 30, and carries each part along with the holder 50 and the hose 60 from the ceiling inspection opening to the attic space. First, identify the source of water leakage, such as the foundation above the attic, and determine the seat installation area below it.

Once the suspension bolts in the sheet installation area are identified, the support sheets 30 are installed side by side on several suspension bolts 120 lined up in a predetermined direction. Here, one support sheet 30 is installed for every three hanging bolts 120 along the direction in which the field edge receiving material 130 extends.

When installing the support sheet 30, first, the holder 50 is attached to the hanging bolt 120 and fixed. The holder 50 is configured by a clip here, and is fixed by sandwiching the hanging bolt 120. In FIG. 2, nine holders 50 are installed on the hanging bolts 120 in accordance with the sheet installation areas of the two liquid receiving sheets 20. Furthermore, the further the holder 50 is on the back side of the page, the higher the position is.

Next, the support sheet 30, which is divided into a pair of belt-shaped sheets 30A and 30B, is aligned with the longitudinal direction of the liquid receiving sheet 20, and the mounting fastener 40 is closed with the hanging bolt 120 sandwiched therebetween. At this time, the mounting fastener 40 is closed from the center outward with the support sheet 30 on the holder 50 (see FIG. 3). As a result, the support sheet 30 is placed on the holder 50 in an inclined state and attached to the hanging bolt 120.

After attaching the support sheet 30, the liquid receiving sheet 20 is faced to the support sheet 30, and the connection fastener 35 is closed from the high position side to the home position side. As a result, as shown in FIG. 2, the liquid receiving sheet 20 is connected to the support sheet 30 and positioned in an inclined state between the adjacent hanging bolts 120.

When the liquid receiving sheet 20 is attached to the hanging bolt 120, the drainage fitting 65 is attached to the lower position side of the liquid receiving sheet 20. Then, one end of the hose 60 is attached to the drain fitting 65, and the other end is inserted into the container.

As described above, according to the present embodiment, the liquid receiving device 10 includes the liquid receiving sheet 20 and the support sheet 30, and the liquid receiving sheet 20 is connectable to the supporting sheet 30 via the connection fastener 35. Then, the support sheet 30 is installed on the hanging bolt 120 arranged in the space under the ceiling, and by closing the connection fastener 35, the liquid receiving sheet 20 is connected to the supporting sheet 30 on both sides, and the liquid receiving apparatus 10 is connected to the supporting sheet 30 on both sides. is installed on the hanging bolt 120.

The sheet structure in which the liquid receiving sheet 20 is supported by the support sheet 30 and the removable connection structure using the connection fastener 35 and the mounting fastener 40 enable the installation work of the liquid receiving device 10 in a short time with a simple configuration, and can be done reliably. It becomes possible to extract water in case of water leakage, etc. Further, since the liquid receiving device 10 is configured as an assembly, it can be carried, expanded, and maneuvered freely even in the narrow ceiling of the working space where the hanging bolt 120 is installed, and work can be carried out efficiently. Furthermore, since the hanging bolts 120 are regularly arranged and extend in the vertical direction, the liquid receiving device 10 can be installed at any desired location and height from the ceiling.

The width W of the liquid receiving sheet 20 has a length corresponding to the distance L2 between adjacent bolts 120, and it is possible to connect a number of liquid receiving sheets 20 via the support sheet 30. The size of the area where the 10 sheets are spread can be freely set. Furthermore, since the arrangement length L1 of the mounting teeth 44 of the support sheet 30 is shorter than the length (corresponding to L) of the connection teeth 42 of the support sheet 30, the spacing between adjacent hanging bolts 120 may be slightly different. Even in such a case, the entire support sheet 30 can be installed on the hanging bolts 120.

The length L in the longitudinal direction of the liquid receiving sheet 20 may be set to the distance between four or five hanging bolts 120 arranged in a row, or may be set to a length corresponding to an integral multiple of the distance interval L3 between adjacent hanging bolts 120. good. Alternatively, the width W of the support sheet 30 may be set at a distance L2 between adjacent hanging bolts 120 along the direction of the field edge 100, and the support sheet 30 may be arranged to extend in the direction of the field edge 100.

The width W and length L of the liquid receiving sheet 20 may be determined according to the degree of deflection of the liquid receiving sheet 20, and may also be adjusted according to the width of the support sheet 30. It is not necessary to set it strictly according to the distance intervals L2 and L3 of the hanging bolts 120, and it is sufficient to set it within a range where the liquid receiving sheet 20 does not come into contact with the ceiling finish when it is bent. It is also possible to arrange the liquid receiving sheet 20 in contact with the ceiling.

The polyester liquid receiving sheet 20 and support sheet 30 are foldable and stretchable, so it is easy to connect the liquid receiving sheet 20 to the support sheet 30. Even when the connecting fastener 35 and the mounting fastener 40 are pulled, the connecting fastener 35 and the mounting fastener 40 can be easily opened and closed.

Since the connection fastener 35 has a water-stopping property with almost no water leakage from its engaging portion, there is no fear that water accumulated in the liquid receiving sheet 20 will leak to the ceiling finish. Further, since the liquid receiving sheet 20 and the support sheet 30 can be connected simply by moving the slider 46, the attachment work can be easily performed. Since the fasteners 40 of the support sheet 30 also have water-stop properties, water leakage from around the hanging bolts 120 is suppressed, and a simple rain closure is realized.

Further, regarding the support sheet 30, the pair of belt-shaped sheets 30A and 30B can be integrated and separated by opening and closing the mounting fastener 40. Thereby, the support sheet 30 can be easily installed on the hanging bolt 120. Furthermore, by closing the mounting fastener 40 until it hits the hanging bolts 120, water leakage can be prevented even when the hanging bolts are lined up at different distances.

The support sheet 30 can be installed at a predetermined height of the hanging bolt 120 simply by placing it on the holder 50, and the supporting sheet 30 can be easily installed on the hanging bolt 120. In particular, since the holder 50 is composed of a clip, the holder 50 can be easily installed. The support sheet 30 is stabilized by being pulled by being connected to the liquid receiving sheet 20.

If use is considered in a situation where the amount of water leakage is small, a curtain rail or the like may be installed on the hanging bolt instead of the support sheet 30, and the liquid receiving sheet may be attached to the curtain rail. Further, a holder other than a clip may be used, and other holding means such as hanging the liquid receiving sheet 20 may be used. As for the material of the liquid receiving sheet 20, a foldable, stretchable synthetic resin sheet made of polyester or more may be used.
