Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening obturator, and more particularly to an opening obturator that can improve the simplification and speed of work and can reliably close an opening.

[0002]

2. Description of the Related Art A floor slab of a structure such as a building is provided with a sleeve hole for plumbing such as water and sewage, electricity and gas. Piping is arranged in this sleeve hole, but since the size of the piping is not constant, there is a sleeve hole that is larger than the piping in the floor slab. The opening (gap) between and is closed by a blocking material such as mortar.

However, due to the construction work, it takes many days until the piping work is completed and the closing work is completed. By the time the closing work is completed, water is used in the work process or becomes rain, so that water and rain collect and the dirty water flows down from the sleeve hole to the downstairs. In order to prevent this, it is known to close the sleeve hole with a veneer plate or the like.

[0004]

However, in the above-mentioned prior art, although water can be prevented from flowing downstairs, in order to actually close the sleeve hole with the plywood plate, the sleeve hole must be moved so that it does not move. There has been a problem in that means for forming a protrusion that matches the hole diameter or providing a fixing means must be provided.

In view of these circumstances, the present invention mounts a mounting member that covers the upper surface of the sleeve hole of the floor slab, and mounts it between the flange member provided on the mounting member and the vertical moving plate. An object of the present invention is to provide an opening obturator in which an elastic member is bulged by compression to close a sleeve hole.

[0006]

The present invention employs the following technical means in order to solve the above-mentioned problems. According to the first aspect of the present invention, there is provided a mounting member, which is a blocker for a sleeve hole for plumbing provided in a floor slab of a building, and which straddles an upper surface of the sleeve hole of the floor slab, and a lower surface of the mounting member. Is provided with a flange member capable of loosely fitting in a sleeve hole provided with two or more regulating guide members, and further, a mounting member is screwed with a tightening bolt and a nut provided in a vertical moving plate loosely fitted in the sleeve hole. The vertical moving plate is formed with a guide hole into which the regulating guide member is inserted, and an elastic member that bulges due to compression is interposed between the flange member and the vertical moving plate. .

[0007] According to the second aspect of the present invention, the first aspect is provided.
In addition to the opening obturator, the technical means of forming the lower surface of the flange portion and the upper surface of the upper and lower moving plates into a substantially spherical portion in order to make the elastic member easily bulge due to compression.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention makes it possible to easily close a sleeve hole of a floor slab before starting piping work.

This is because the elastic member having the sleeve hole of the floor slab interposed between the flange member and the vertical moving plate is screwed by the mounting member, the bolt provided on the vertical moving plate, and the nut to be compressed. The opening blocker is configured to block the sleeve hole by bulging outward.

The opening obturator will be described in more detail with reference to a specific embodiment. The obstruction device for a sleeve hole for piping work provided in a floor slab of a building covers the upper surface of the sleeve hole of the floor slab. Such a mounting member, and a flange member which can be loosely fitted in a sleeve hole provided with two or more regulation guide members on the lower surface of the mounting member are further provided, and the mounting member and a vertical moving plate loosely fitted in the sleeve hole. Is configured to be screwed with a tightening bolt and a nut, and a guide hole into which the regulation guide member is inserted is formed in the vertical moving plate, and bulges due to compression between the flange member and the vertical moving plate. An elastic member can be interposed.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. First, the opening obturator according to the first embodiment of the present invention will be described with reference to FIGS. 1 and 2.

Sleeve hole 2 for arranging piping in floor slab 1
It is necessary to close the sleeve hole 2 until the pipe is penetrated through the sleeve hole 2. The floor slab 1 is provided with a sleeve hole 2 slightly larger than the pipe outer diameter, and the sleeve hole 2 needs to be closed until the pipe is arranged.

Therefore, as a first embodiment, as shown in FIG.
This will be described in detail with reference to FIG. A mounting member 4 having a size straddling the floor slab upper surface 3 is provided so as to close the sleeve hole 2 formed in the floor slab 1, and the flange member 5 provided on the mounting member 4 is loosely fitted to the floor slab upper surface 3. Let them straddle.

A flange member 5 is fixedly mounted on the lower surface of the mounting member 4 so that it can be loosely fitted in the sleeve hole 2. Two or more regulating guide members 6 are provided on the flange member 5, and the mounting member 4 is further provided. A hole into which the tightening bolt 7 can be inserted is bored in the flange member 5, and the bolt 7 integrally provided in the vertical moving plate 8 loosely fitted in the sleeve hole 2 is inserted and screwed with the nut 15. It is a thing. A guide hole 10 into which the regulation guide member 6 is inserted is formed in the vertical moving plate 8, and an elastic member 11 that bulges due to compression between the flange member 5 and the vertical moving plate 8 is interposed, and a flange member is formed. Only the vertical movement is performed while being regulated by the regulation guide member 6 fixedly provided on the No. 5 and the guide hole 10 formed in the vertical movement plate 8, whereby the flange is formed by screwing and tightening the tightening bolt 7 and the nut 15. The elastic member 11 interposed between the member 5 and the vertical moving plate 8 is compressed and bulges outward to close the sleeve hole 2.

Next, the second aspect of the present invention will be described with reference to FIGS.
An embodiment will be described. The difference from the first embodiment is that the elastic member 11 interposed between the flange member 5 and the vertical moving plate 8 that bulges due to compression is bulged more easily and surely to occupy the sleeve hole. In this configuration, the lower surface 12 of the flange portion and the upper surface 13 of the vertical moving plate are formed into a substantially spherical portion 1.
4, the mounting member 4 and the flange member 5 are integrally provided with a tightening bolt 7 so as to be screwed with a long nut 9 provided on a vertical moving plate 8 which is loosely fitted in the sleeve hole 2. However, since all others are the same, detailed description will be omitted.

[0016]

As a result of adopting the above configuration, the present invention provides
The following effects can be obtained. (1) The sleeve hole can be closed by swelling the elastic member outward only by tightening the bolt and nut. Moreover, it is excellent in safety, easiness and speed of work, and the construction cost is low.
