Description

The present invention relates to a building foundation water collecting basin device that is installed in a building foundation slab to collect water such as rainwater and drain it into the ground.

In general, the foundation of a building is constructed by laying a crushed stone layer on the foundation ground, placing a discarded concrete layer and a foundation slab layer on top of each other, and then installing a floorboard above the foundation slab layer. .. However, since the upper surface of the foundation slab layer is almost horizontal, when it rains and water collects on the upper surface of the foundation slab layer under the floor, there is no place to collect water, so it takes time and effort to treat this residual water. For this reason, in the past, a worker went under the floor at an appropriate place at a key point and treated the residual water using a dry wiper, a water-absorbing sponge, or the like. Further, even before the building was constructed above the foundation slab layer, rainwater collects on the upper surface of the foundation slab layer, so that the same residual water treatment as described above was required at this point as well.

However, according to the above-mentioned conventional method, the burden of the work itself performed by the worker under the floor is extremely heavy, and the burden of using a dry wiper, a water-absorbing sponge, or the like is also heavy.

An object of the present invention is to provide a building foundation water collecting basin device capable of collecting rainwater and the like and draining them efficiently by providing a water collecting basin device in the foundation slab layer of the building.

It is a cross-sectional view along the IV-IV line and the cross-sectional view along the VV line.

In FIG. 1, the water collecting basin device 1 generally includes a water collecting basin member 2, a lid member 4, and a support member 9. The catchment basin member 2 is formed of a weather-resistant resin material such as hard vinyl chloride, and as shown in FIGS. 3 to 8, the catchment sloping portion 2a1 and the cylindrical wall portion are gently inclined toward the center. A bottomed cylinder-shaped catchment basin 2a integrated with 2a2, a drainage cylinder portion 2b at the center bottom, and flange portions 2c (having holes 2d) provided at four outer circumferences of the catchment basin 2a. Is provided integrally. Further, an outer peripheral groove 2e (see FIGS. 2 and 8) is provided on the outer periphery of the catchment basin portion 2a. Further, as shown in FIGS. 6 and 8, the drainage cylindrical portion 2b has an upper inner peripheral step portion 2f, a bottom step portion 2g, and a pair of engaging convex portions 2h on the inner peripheral surface. An anti-termite ring 3 for preventing termites from climbing up to the outer peripheral groove 2e of the catchment basin 2a is attached. (See FIGS. 1, 2 and 8)

As shown in FIGS. 9 to 11, the lid member 4 is a bottomed tubular member formed of a resin material having weather resistance such as rigid vinyl chloride, and has a pair of knob recesses 4a on the upper surface and an upper outer periphery. It has a step portion 4b and a pair of L-shaped engaging recesses 4c extending upward from the lower end. As will be described later, an ant-proof ring 5 is attached to the inner circumference of the drainage cylinder portion 2b. (See FIGS. 2 and 6) In FIGS. 3 to 5, the ant-proof rings 3 and 5 are not shown. The anti-termite ring is formed from a synthetic rubber material such as ethylene propylene rubber.

Reference numeral 6 is a filter member, in which a filter net 8 made of resin or stainless steel is embedded in a rubber packing ring 7 as shown in FIGS. 12 and 13.

The support members 9 are provided in pairs as shown in FIGS. 1 and 2, and each support member 9 is erected by attaching a pair of bolts 11 to a support plate 10 made of a corrosion-resistant metal (stainless steel or the like) by a nut 12. To.

Subsequently, the assembly of the water collecting basin device 1 of the present invention will be described.
First, the filter member 6 is dropped into the drainage cylindrical portion 2b of the catchment basin 2 from above and brought into contact with the bottom step portion 2g. Subsequently, the ant-proof ring 5 is placed on the upper surface of the inner peripheral step portion 2f of the drainage cylindrical portion 2b. Subsequently, the lid member 4 is also dropped into the drainage cylindrical portion 2b from above, and while operating by inserting a finger into the knob recess 4a of the lid member 4, first, the axial groove portion of the pair of L-shaped engaging recesses 4d is formed. The lower end of the is moved downward while engaging with the pair of engaging convex portions 2h. Then, when each engaging convex portion 2h comes into contact with the upper end of the axial groove portion of each engaging concave portion 4d, the lid member 4 is rotated clockwise by a predetermined angle in FIG. Then, the rotation of the lid member 4 is stopped when each engaging convex portion 2h comes into contact with the end portion of the horizontal groove portion of each L-shaped engaging concave portion 4d. Thus, the drop attachment (locking) of the lid member 4 to the drainage cylindrical portion 2b is completed. As a result, it is possible to prevent the lid member 4 from being unintentionally disengaged by not only dropping the lid member 4 downward but also rotating the lid member 4 by a predetermined angle after dropping the lid member 4. At this time, the upper outer peripheral step portion 4b of the lid member 4 abuts on the upper inner peripheral step portion 2f of the drainage cylindrical portion 2b with the anti-termite ring 5 interposed therebetween (see FIG. 6). In the above embodiment, the drainage cylinder portion 2b is provided with the engaging convex portion 2h and the lid member 4 is provided with the L-shaped engaging concave portion 4d, but the present invention is not limited to this, and the drainage cylindrical portion 2b is provided with the L-shaped engaging portion. A concave portion may be provided and the lid member 4 may be provided with an engaging convex portion, or an engaging convex portion and an engaging concave portion may be provided respectively.

As a result, the termite-proof ring 5 attached to the lid member 4 liquidally seals the gap (boundary portion) between the outer circumference of the lid member 4 and the inner circumference of the drainage cylinder portion 2b, so that the water is collected in the catchment basin 2. Water does not leak from here, and termites and the like can be prevented from climbing through the drainage cylinder portion 2.

Subsequently, the upper end portions of the pair of bolts 11 of one support member 9 are inserted through the holes 2d of the pair of flange portions 2c of the catchment basin member 2 from the lower side to the upper side, and the double nut 13 (see FIGS. 1 and 2) is inserted. ) To be tightened and fixed. The other support member 9 is similarly attached to the other pair of flange portions 2c. Thus, the water collecting basin device 1 is completed. Therefore, the height of the catchment basin member 2 is adjusted by loosening or tightening the double nut 13 of each support member 9 to adjust the dimension in which each bolt 11 protrudes upward from the flange portion 2c of the catchment basin member 2. The height and inclination can be finely adjusted as appropriate.

Subsequently, the procedure for attaching the catchment basin device 1 to the foundation of the building will be described using the foundation cross-sectional view of FIG. 14. In the figure, 15 is the foundation ground, and the crushed stone layer 16 is discarded. The concrete layers 17 are sequentially formed. At this point, the water collecting basin device 1 is installed in one place for a single building, for example, on the upper surface of the waste concrete layer 17 in a place corresponding to a kitchen via a pair of support members 9. After that, by adjusting the pair of support members 9 as described above to adjust the height and inclination of the catchment basin member 2, the upper end portion of the catchment basin member 2 is a concrete foundation slab layer to be cast later. The height is set so as to match the upper surface 18a of 18. Next, the drainage pipe 19 is connected to the drainage cylinder portion 2b. Note that 20 is the ground level.

Therefore, during the period in which the foundation slab layer 18 is left to stand after being placed, for example, when it rains, the operator can collect the rainwater on the upper surface 18a of the foundation slab layer toward the water collecting basin device 1 to stop the foundation slab layer 18. When the amount of water reaches a certain amount, when the operator rotates the lid member 4 in the counterclockwise direction opposite to that at the time of mounting and lifts the lid member 4, the engaging convex portion 2h and the engaging concave portion 4d are disengaged. The lid member 4 can be removed from the catchment basin 2a. Therefore, the water accumulated in the catchment basin 2a is drained by gravity to the pipe 19 via the drainage cylinder 2b, or is forcibly drained by a pump (not shown) connected to the pipe. At this time, the relatively large dust mixed in the wastewater is filtered by the filter member 6, so that the operator removes it. Then, after the drainage is completed, the lid member 4 is reattached. When the amount of water is small, the water collecting basin device 1 may be used simply as a kettle for collecting and storing water without removing the lid member 4.

Subsequently, in the building, the mortar layer 21, the foundation packing 22, and the base 23 are placed on the rising portion of the foundation slab layer 18, and the floor plate 24 and the wall 25 of the building are further formed. The water collecting basin device 1 remains installed even after the building is completed. Therefore, if the water collecting basin device 1 is arranged directly under the underfloor inspection port 26 of the floor plate 24, for example, when the underfloor is flooded due to heavy rain, the lid member 4 can be operated by reaching out from the underfloor inspection port 26. Can be easily drained. Therefore, when the water collecting basin device 1 is not provided, it is not necessary to carry a drainage pump under the floor to drain water.

The drainage pump does not necessarily have to be provided.
