Provide a beneficial drainage drain. [Structure] A strainer, a mounting band with a nail hole that is fitted and tightened on the bottom of the outer peripheral surface of the strainer, a receiving frame with a taper that fits over the strainer, and its receiving frame. The drain, which is detachably fitted to the upper inner portion of the above, and the strainer, the mounting band, the receiving frame, and the drain are each made of synthetic resin. Further, it is characterized in that a claw portion which is fitted to the upper inner peripheral surface of the receiving frame with appropriate resistance is integrally formed at a proper position on the outer periphery of the drain.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a drainage drain made of synthetic resin for treating wastewater on concrete floors such as balconies and balcony.

[0002]

[Prior art]

 Conventionally, this type of drainage drain is made of cast metal, so it is liable to rust over a long period of time and has a problem with durability. Also, it is heavy in handling and inconvenient. In addition, it is a means to screw onto the mounting seat, which has been nailed in advance, on the formwork with a single stat bolt from above the drain.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional method, when the floor concrete is cast, the floor pressure is often tilted or displaced due to the side pressure of the concrete, so that the mounting accuracy is significantly reduced.

[0004]

[Means for Solving the Problems]

 The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to improve rust prevention performance, to make it light and easy to handle, which is advantageous, and to be easily and reliably mounted on a formwork. It provides a drainage drain made of synthetic resin, which is practically useful. Further, the present invention provides a practically convenient drain drain made of synthetic resin, which is easy and easy to install and remove the drain.

As a means thereof, a strainer, a mounting band with a nail hole that is fitted and tightened on the outer peripheral bottom portion, and a receiving frame with a taper that is fitted on the upper portion of the strainer. A drainage drain made of synthetic resin, characterized in that the drain, which is detachably fitted to the inside of the upper part of the receiving frame, is made of synthetic resin for the strainer, the mounting band, the receiving frame and the drain. Further, it is characterized in that a claw portion which fits with appropriate resistance to the upper inner surface of the receiving frame is integrally formed at a proper position on the outer peripheral surface of the drain.

With the above structure, it is possible to solve the above-mentioned conventional problems such as exhibiting a rust preventive effect, light and easy to handle, easy and reliable mounting on a mold, and high mounting accuracy.

【Example】

 An embodiment of the present invention will be described in detail with reference to the drawings. 1 is a partial vertical sectional view showing an embodiment of the present invention, FIG. 2 is a plan view of a mounting band, and FIG. 3 is a partial plan view of a drain. The strainer 1 made of synthetic resin is formed by integrally forming a concave groove 11 along a part of a cylindrical outer circumference. The mounting band 2 made of a synthetic resin integrally provided with the nail hole 21 is fitted and tightened on the bottom of the outer peripheral surface of the strainer-1, and the ear piece 22 at the opening end is screwed with the bolt B and the nut N. Wear and tighten. The receiving frame 3 made of synthetic resin is integrally formed with a taper portion 31 at a lower portion and provided with a stepped inner peripheral surface for fitting a drain at an upper portion. The drain 4 made of synthetic resin is detachably fitted to the inner peripheral surface of the receiving frame 3. A large number of drainage holes 41 are provided on the upper surface of the circular plate, and the outer peripheral surface of the drain 4 is provided at an appropriate position inside the upper portion of the receiving frame 3. The claw portion 42 that fits with appropriate resistance to the peripheral surface is integrally formed.

Next, a method of using the embodiment of the present invention will be described. As shown in FIG. 4, a mounting band 2 is fitted on the outer periphery of the bottom of the strainer 1 on a form P such as a veranda or a balcony, and the mounting band 2 is nailed A. The receiving frame 3 is fitted on the upper part of the strainer-1, and the floor concrete C is placed along the outer periphery of the upper surface thereof. In this case, an appropriate cover (not shown) is put over the inside of the strainer-1 and the receiving frame 3 so that the concrete does not flow in. After curing the concrete, the mold P is removed from the mold, while a drain is fitted to the upper inner surface of the receiving frame 3, and at the same time, the drain pipe D is inserted into the taper portion 31 of the receiving frame 3. It will be constructed. Incidentally, E in the figure is a water-expandable water-blocking material wound around a concave groove 11 formed in a part of the outer peripheral surface of the strainer-1.

[0009]

[Effect of device]

 As described in detail above, according to the drain drain made of synthetic resin of the present invention, the following effects can be obtained, and the drain drain made of synthetic resin which is practically useful can be obtained. 1. Since the strainer, mounting band, receiving frame, and drain are all made of synthetic resin, they have excellent rust prevention performance. 2. It is light and easy to handle and convenient. 3. Since the outer peripheral surface of the strainer is clamped on the formwork by the mounting band with nail holes, it is possible to perform reliable and stable mounting with excellent workability. 4. The claws that are integrally formed along the outer peripheral surface of the drain ensure secure fitting to the receiving frame, and mounting and dismounting are simple and easy.
