Description

[Detailed description of the invention] Industrial application field This invention relates to a horizontal drainage device for collecting rainwater and floor washing water that accumulates on the roof of a building, and discharging it horizontally from the floor.

Conventional technology Conventionally, horizontal drainage and drainage equipment for draining rainwater accumulated on the roof of a building, etc., has an almost L-shaped drain outlet in front of the drain opening at the corner where the wall and floor of the roof intersect, for example. Attach the main body of the drain collection device formed into a plate shape, and install the plant bolt into the main body by screwing the lower end of a plant bolt made of brass or the like into the screw hole provided in the main body itself, and then , by placing a presser fitting with a bolt hole penetrated on the main body, inserting a stud of the main body into the bolt hole and screwing a nut onto the tip of the stud, the main body The terminal portion of the waterproof sheet is sandwiched between the presser metal fitting and the presser metal fitting while being tightened.

Problems that the invention aims to solve: Because the main body and retainer of conventional drainage equipment are usually made of cast iron, rainwater tends to corrode the mounting parts and threaded parts of the bolts over many years of use. In some cases, it became difficult to remove the holding metal fittings, or the holding metal fittings were not pressed down sufficiently, causing the waterproof sheet to lift up and cause rain to leak.

Now, in the conventional structure mentioned above,
Even if the attachment part or threaded part of the plant bolt is simply corroded, the main body of the drainage equipment itself has to be replaced, which has the disadvantage that the replacement work is large-scale and the replacement cost inevitably increases. Ta.

Means for Solving the Problems The present invention presses the retaining metal fitting against the main body of the water collection device by simply locking the locking member without directly screwing the stud bolt into the main body itself. This device is characterized by a configuration in which the holding member is pressed against the main body by connecting the stop member and the pressing member with a screw rod, thereby solving the drawbacks of the conventional water collection device. .

Function: The horizontal water collection device of the present invention has no screw attachment or threaded portions on the main body itself or the presser fitting, so it has no parts that are prone to corrosion and is highly durable.
Even in the event that the threaded part of the screw rod becomes corroded due to long-term use, there is no need to replace the main body or the retaining metal fittings, and you can simply replace the screw rod, which simplifies the replacement work and significantly reduces the cost. You can save money.

Example An embodiment of the present invention will be described based on the drawings.

Hereinafter, for convenience, the right side of the figure will be referred to as the front side, and the left side will be referred to as the rear side.

Now, in the figure, 1 is the main body of the drainage device, which is made of a metal plate with a smooth surface such as a stainless steel plate or a light alloy plate.
It has a vertical plate 2 bent at an acute angle close to 90 degrees to form a substantially L-shaped plate, and a substantially horizontal base plate 3. A substantially rectangular drain port 4 is opened at the lower center end of the vertical plate 2, and a drain pipe 5 having a substantially rectangular cross section is connected to the drain port 4 behind the drain port 4. There is. Moreover, the left and right triangular surfaces of the base plate 3, which are formed by a straight line from the corner of the front end of the base plate 3 to the edge of the drain port 4, are bent in an inclined shape with the edges slightly upward. It is formed so that running water naturally collects at the drain port 4.

Further, the inner bottom surface of the drain pipe 5 is formed to be flush with the plane of the middle part of the base plate 3, or to be sloped so that the rear end is slightly lower than the plane, so as to improve the drainage effect. .

Next, the drain pipe 5 has a substantially semi-disc-shaped recess 6 in the center of the upper surface of the distal end thereof, and is formed to be able to lock a rear hook portion 15 of a locking member 13, which will be described later.

Reference numeral 7 denotes a presser metal fitting for pressing the edge of the waterproof sheet 27, and like the main body 1 of the water collection device, a metal plate with a smooth surface such as a stainless steel plate or a light alloy is folded at an angle close to 90 degrees. It is provided with a vertical plate 8 which is bent into a substantially L-shaped plate shape and a substantially horizontal horizontal plate 9, and a drain port 10 is opened at the lower center end of the vertical plate 8. Furthermore, ribs 11 are formed on the peripheral edges of the vertical plate 8 and the horizontal plate 9 by press molding or the like to provide rigidity, and two locking protrusions 12 are provided on the left and right sides of the top of the vertical plate 8, respectively. Furthermore, there are locking protrusions 12 on the left and right sides of the front part of the horizontal plate 9.
There are two protruding pieces. Also, like the main body 1, the left and right triangular surfaces formed by the straight line from the front corner of the horizontal plate 9 to the edge of the drain port 10 are bent slightly upward, and the presser metal fitting 7 When placed on the upper surface of the main body 1 of the water collection/drainage device, its vertical plate 8 and horizontal plate 9 are formed so as to be in close contact with the vertical plate 2 and base plate 3 of the main body 1.

Reference numeral 13 denotes a locking member formed of a square or round metal bar, whose front and rear ends are bent in opposite directions to form a front hook portion 14 and a rear hook portion 15, Further, a regulating piece 16 is provided to protrude left and right at approximately the middle position of the entire length. Note that the length between both ends of the regulating piece 16 is approximately the same as the lateral internal measurement dimension of the drain pipe 5 of the main body 1. Also 1
Reference numeral 7 denotes a screw rod, and the hook portion 18 is formed by bending the rear end of a round metal rod with a screw cut into the front half and a wing nut 19 screwed into the rod.

Reference numeral 20 denotes a pressing member formed of a metal plate in the shape of a cross, each protruding piece being curved into an arc, and a bolt hole 21 passing through the center of the cross. 2
Reference numeral 2 denotes a dustproof cap, which has flat side plates 24 on both left and right sides of a front plate 23 made of a thin metal plate curved into an arc shape. The angle is approximately equal to the curved angle, and the end face and lower face are open, and the inside is hollow. In addition, a bolt hole 25 is provided in the approximately central part of the front surface, and a front plate 23 is provided.
A suitable number of elongated holes 26 are provided through the left and right side plates 24. 27 shows a waterproof sheet spread on the floor of the roof.

When installing the horizontal water collection and drainage equipment of this example on the roof of a building, etc., as shown in Fig. The drain pipe 5 of the main body 1 of the water collection device is inserted, the vertical plate 2 is brought into contact with the inner surface of the wall K, and the base plate 3 is placed on the floor surface F of the roof. In this case, the floor surface F that the base plate 3 comes into contact with is formed so as to be slightly inclined toward the wall K side. Next, place the edge of the waterproof sheet 27 spread on the floor surface F on the base plate 3, place the presser metal fitting 7 on top of it, and bring the vertical plate 8 into close contact with the vertical plate 2 of the main body 1.
Drain port 10 of presser fitting 7 and drain port 4 of main body 1
The rear part of the locking member 13 is inserted further, and then the hook portion 15 is hooked into the recess 6 of the drain pipe 5, and the front hook portion 14 is caused to protrude forward. In this case, the restricting piece 16 of the locking member 13 comes into contact with the inside of the drain pipe 5 and is restricted to the center position of the drain pipe 5.

Next, the screw rod 17 inserted into the bolt hole 21 of the pressing member 20 is brought into contact with the vertical plate 8 and the horizontal plate 9 of the presser metal fitting 7, and its edge is locked in the locking protrusion 12,
After the hook portion 18 of the screw rod 17 is hooked to the front hook portion 14 of the locking member 13, when the wing nut 19 is screwed onto the screw rod 17 and screwed, the wing nut 1
9 presses the pressing member 20 against the presser fitting 7 and strongly presses the waterproof sheet 27. Next, the dust-proof cap 22 is placed on the presser metal fitting 7, and the bolt hole 25 is inserted into the tip of the screw rod 17, and the wing nut 19 is screwed together to removably fix the dust-proof cap 22. Note that the distal end of the drain pipe 5 protruding to the outside of the wall K is inserted into the upper part of the downspout to enable drainage.

Now, in the above-mentioned water collection device, when rainwater collects on the floor of the roof, the rainwater flows on the waterproof sheet 27 and reaches the water collection device, and the elongated hole 2 of the dustproof cap 22
6, flows over the upper surface of the horizontal plate 9 of the presser fitting 7, passes through the drain port 10 thereof and the drain port 4 of the main body 1, reaches the inside of the drain pipe 5, and flows down into the downpipe to be drained.

The main body 1 and the presser fitting 7 are made of stainless steel plate,
In addition to the light alloy plate, it can also be formed of a brass plate or other material, such as hard synthetic resin, which has appropriate rigidity and has a smooth surface.

Furthermore, although the pressing member 20 has a cross shape with the ends of the metal plate extending in all directions, it may also have a shape extending in two directions, and the rear part of the drain pipe 5 of the main body 1 may be cylindrical.

Further, the front end of the locking member 13 does not necessarily need to protrude forward from the drain port, but may be connected to the rear end of the screw rod at the rear of the drain port.

The shape of the dustproof cap 22 is also not limited to that of the embodiment.

Furthermore, when installing the dustproof cap 22, a screw rod 17 is used.
It is also possible to detachably attach the pressing member 20 using a separate bolt or the like.

Furthermore, a technique is also foreseen in which the pressing member has a shape that also serves as a dustproof cap, thereby omitting the dustproof cap.

Effects of the Invention The horizontal water collection and drainage device installed on a rooftop or the like according to the present invention has a locking member 13 whose one end is locked to a part of the main body, such as a drain pipe, in order to press the holding fitting 7 that is in close contact with the main body 1. Since the screw rod 17 and the nut connected to the other end are used to press through the pressing member 20, there is no bolt or bolt attachment part implanted in the main body, which is conventional, and the device is highly durable. Furthermore, even if the threaded portion of the bolt corrodes due to long-term use, there is no need to replace the main body itself, and the effect of the present invention is extremely large.
