Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loop packing used for preventing a pipe noise or the like of a drain pipe inserted into a beam sleeve provided on a beam.

[0002]

2. Description of the Related Art As is well known, some beam materials used as building beams are provided with beam sleeves. It is known that after arranging such a beam at a predetermined position, a tube such as a drainage tube, a water supply tube, or a hot water supply tube is inserted into the beam sleeve and piped.

[0003] When pipes of the water supply pipe or hot water supply pipe are often inserted in a substantially horizontal direction in the inside of the beam sleeve, when the pipes of the drainage are piped, drainage is caused to flow down. For this reason, it is often inserted with a gradient.

[0004]

Here, in addition to the case where the drainage pipe is inserted with a gradient as described above, the case where the water supply pipe or the hot water supply pipe is inserted in a substantially horizontal direction. Also, these drainage pipes may come into contact with the inner peripheral surface of the beam sleeve. However, in many cases, no countermeasures are taken even when the drainage pipes and the like come into contact with the beam sleeve, so that the sound of water flowing through the drainage pipes and the like is transmitted to the beams to generate pipe noise. There is a problem.

[0005] As a countermeasure for preventing the above-mentioned pipe noise, a cushioning material of a predetermined shape may be interposed between the inner peripheral surface of the beam sleeve and a drainage pipe or the like. There is a problem that the operation is complicated.

Further, a beam material provided with a beam sleeve is difficult to clearly distinguish from other ordinary beam materials not provided with a beam sleeve and can be diverted to other positions. There is a case where a member is misplaced at another position, and another ordinary beam is placed at a position where the beam should be placed. In such a case, since there is no beam sleeve at the position where the drainage pipe etc. should be inserted, the original design was changed and the drainage pipe etc. was piped below the beam, and the lower floor ceiling was lowered further. There is a problem that it is necessary to perform the construction.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and is easy to attach to a beam sleeve.
Moreover, it is an object of the present invention to provide a loop packing of a beam sleeve, which can prevent noise of piping such as a drain pipe inserted into the beam sleeve, and can prevent misplacement of the beam material provided with the beam sleeve.

[0008]

According to another aspect of the present invention, there is provided a loop packing fitted to at least one opening edge of a beam sleeve provided on a beam material. 2 can be fitted inside the opening edge of
The two clamping annular pieces and a connecting member connecting the two clamping annular pieces are formed in an annular shape having a substantially U-shaped cross section,
There is provided a packing body made of a synthetic resin in which a protruding portion is formed on the inner surface of one of the sandwiching annular pieces, and a cushioning material closely attached to the inner peripheral surface of the packing body.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1 to FIG.
The loop packing 1 according to the embodiment is to be fitted to at least one opening edge 3a (3b) of a beam sleeve 3 provided on a beam 2 used as a beam of a building.

The loop packing 1 includes two clamping annular pieces 4a capable of fitting the opening edge 3a (3b) of the beam sleeve 3 inside, and a connecting member 4b for coupling the two clamping annular pieces 4a. And a packing body 4 made of synthetic resin, which is formed in an annular shape with a substantially U-shaped cross section and has a protruding portion 5 formed on the inner surface of the two clamping annular pieces 4a, and an inner peripheral surface 4c of the packing body 4. And a cushioning material 6.

As shown in FIG. 1, the packing body 4 is formed in an annular shape having a substantially U-shaped cross section, and includes two clamping annular pieces 4a.
And a connecting member 4b for connecting the two sandwiching annular pieces 4a, and is made of, for example, a synthetic resin such as hard or semi-hard plastic. Therefore, the two clamping annular pieces 4a are elastically deformable outward.

An opening 7 formed by the two holding annular pieces 4a faces one surface 4d of the packing body 4, and as shown in FIGS. Can be fitted to the opening edge 3a (3b) from the side. In addition, as shown in FIGS. 1 and 4, near the opening 7 on the inner surface of these two sandwiched annular pieces 4a, for example, two sandwiched annular pieces 4a are inclined inward to each other and their ends 4e are moved outward. The protruding portions 5 are respectively formed by forming a substantially rectangular cross section so as to open. That is, since the distance L between the projections 5 is smaller than the thickness T of the beam sleeve 3, the beam sleeve is opposed to the elastic force of the two clamping annular pieces 4a from the opening 7. When inserting the opening edge 3a (3b), the end 4e is open outward, so that it is easy to insert, and after the insertion, it falls off due to the elastic force of the two clamping annular pieces 4a. Not to be.

The cushioning member 6 is in close contact with, for example, the entire inner peripheral surface 4c of the packing body 4, and is made of a material having a cushioning property (buffering property) such as soft rubber, soft plastic foam, or foamed rubber.

The loop packing 1 constructed as described above
Is at least one opening edge 3a of the beam sleeve 3.
(3b) may be used by fitting it. However, since the beam 2 is often made of steel or the like and is colored black, the beam 2 is noticeable with respect to, for example, white or yellow. The beam sleeve 3 on which the loop packing 1 is fitted can be easily visually recognized if it is colored in an easy color in advance or if necessary after manufacturing. Therefore, if the loop packing 1 is fitted in a factory or the like before carrying the beam material 2 provided with the beam sleeve 3 to the construction site, the beam material 2 or the like is carried into the construction site, When the beam member 2 is arranged at the position, the beam member 2 can be clearly distinguished from other ordinary beam members not provided with the beam sleeve 3, so that there is an advantage that the misplacement can be reliably prevented. Further, if one loop packing 1 is fitted to each of the opening edges 3a, 3b of the beam sleeve 3, there is an advantage that the beam sleeve 3 can be visually recognized from a wider range.

After arranging the beam member 2 at a predetermined position in this state, as shown in FIG. 4, when inserting a pipe member 8 such as a drainage tube member into the beam sleeve 3 for piping, Since the cushioning material 6 is exposed in the beam sleeve 3, the pipe material 8
Does not directly contact the inner peripheral surface 3c of the beam sleeve 3. Even when the pipe member 8 comes into contact with the buffer member 6, the cushioning property of the buffer member 6 makes it difficult for the sound of water flowing in the pipe member 8 to be transmitted to the beam member 2, thereby providing an advantage that pipe noise can be prevented. Furthermore, if one loop packing 1 is fitted to each of the two opening edges 3a and 3b of the beam sleeve 3, there is an advantage that the gradient of the pipe 8 can be further increased.

As shown in FIG. 5, the loop packing 11 according to the second embodiment is different from the first embodiment in that the two clamping annular pieces 4a of the packing body 4 are perpendicular to the connecting member 4b. In addition, they are formed facing each other with a predetermined interval T1, and a plurality of protruding portions 5 are provided in the vicinity of the opening 7 on the inner surface of these two clamping annular pieces 4a in the circumferential direction.

In this loop packing 11, the first
As in the embodiment, when inserting the opening edge 3a (3b) of the beam sleeve 3 from the opening 7, these two clamping annular pieces 4a are substantially the same as or slightly smaller than the thickness T of the beam sleeve 3. Since they are formed facing each other with a large interval T1 therebetween, they can be inserted without difficulty, and after insertion, the two clamping ring pieces 4a which are spread outward by the protruding portions 5 are provided.
It does not fall off due to the elastic force of. In this embodiment, a plurality of protrusions 5 are provided continuously in the circumferential direction of the holding annular piece 4a. However, the present invention is not limited to this. It may be formed so as to extend in the circumferential direction of the piece 4a.

As described above, in the first and second embodiments, the protruding portion 5 is formed near the opening 7 on the inner surface of the two clamping annular pieces 4a. It may be formed, and the formation location, shape, and the like are not particularly limited. In addition, the cushioning material 6 is
Although it is in close contact with the entire inner peripheral surface 4c, the present invention is not limited to this, and it is also possible to adhere to only a predetermined range of the inner peripheral surface 4c. In this case, the loop packing 1 (11) is fitted so that the cushioning material 6 can come into contact with the pipe material 8 or the loop packing 1 (11) is rotated until it can be contacted after being fitted, so that the pipe material 8 is attached to the packing body 4. What is necessary is just to avoid direct contact with the inner peripheral surface 4c.

[0019]

As described above, according to the present invention, there are two clamping annular pieces that can fit inside the opening edge of the beam sleeve and a connecting member that connects these two clamping annular pieces. A packing body made of a synthetic resin having a substantially U-shaped cross section and formed with a protruding portion on the inner surface of the two sandwiching annular pieces, and a cushioning material closely attached to the inner peripheral surface of the packing body. Therefore, if the beam material is colored in advance so as to be conspicuous or after manufacturing as necessary, the beam sleeve fitted with the loop packing can be easily visually recognized. Therefore, before the beam material provided with the beam sleeve is carried into the construction site, if a loop packing is fitted in advance in a factory or the like, the beam material or the like is carried into the construction site and then placed at a predetermined position. In this case, since this beam member can be clearly distinguished from other ordinary beam members not provided with a beam sleeve, there is an advantage that misplacement thereof can be reliably prevented. Further, if one loop packing is fitted to each of the two opening edges of the beam sleeve, there is an advantage that the beam sleeve can be visually recognized from a wider range.

Further, since it is only necessary to fit the opening portion of the beam sleeve, the mounting of the loop packing is simple, and the cushioning material is exposed in the beam sleeve fitted with the loop packing. The tubing does not directly contact the inner peripheral surface of the beam sleeve. Even when the pipe material comes into contact with the buffer material, the sound of water flowing in the pipe material is hardly transmitted to the beam material due to the cushioning property of the buffer material, and thus there is an advantage that pipe noise can be prevented. Further, if one loop packing is fitted to each of the two opening edges of the beam sleeve, there is an advantage that the gradient of the pipe can be further increased.
