Description

[Detailed Description of the Invention] The present invention relates to a sound insulating partition wall for a building, and aims to improve sound insulation, fire prevention performance, and simplify construction.

Partition walls, which are the boundary walls between rooms in concrete structures such as high-rise residential buildings, buildings, and schools, should preferably have excellent sound insulation and fire prevention performance, but there are still cases where the above performance is insufficient. are used in large quantities.

As shown in the cross-sectional plan view of FIG. 6, the conventional partition wall 20 has partition plates 22 and 23 made of gypsum thread board, asbestos cement calcium silicate board, etc. on both sides, sandwiching a base crosspiece 21 made of shaped steel or wood. The structure is double-attached with screws.

In this structure, the soundproof space 24 has only one layer, and when the air vibration of sound excites the partition plate 22.23 on one side, this vibration propagates through the solid vibration in the base crosspiece 21 and causes the partition plate 22.23 on the opposite side to vibrate. Since the sound propagates directly to the partition wall 20, the sound transmission loss within the partition wall 20 is small, and the sound insulation property is extremely low.

In addition, the soundproof space 24 has only one air layer, and the base crosspiece 2
1 is present, heat is easily transmitted through the partition wall 20, and the fire prevention performance of the partition wall 20 is also insufficient.

Furthermore, during construction, the upper and lower ends of the base crosspiece 21 are installed and fixed to the ceiling wall and floor wall side, and after adjusting the flatness of the outer surface of the base crosspiece 21, the partition plates 22 and 23 are attached to the base crosspiece 21. Since a snake stopper must be installed, the required man-hours increase and the construction period becomes longer.

In order to solve the above-mentioned drawbacks, this invention creates a structure in which an air layer is created between the inner and outer partition plates and they are joined with construction adhesive, which greatly increases the rigidity of the partition plates and eliminates the need for foundation crosspieces. At the same time, by creating a three-layer soundproof space, the sound insulation and fireproofing performance of the partition wall is dramatically improved.Furthermore, by bonding the partition plate to the ceiling wall and floor wall with architectural adhesive. At the same time, it is also characterized by simplifying construction by allowing the inner and outer partition plates to be joined.

Next, an embodiment of the present invention will be explained based on the drawings.

As shown in FIGS. 1 and 2, the sound insulating partition wall 1 is a composite structure consisting of two inner partition plates 2, two outer partition plates 3, and three layers of sound insulating spaces 4 and 5 between them. It is a partition wall of the structure, and both upper and lower ends are formed to have a bonded structure with the ceiling wall 6 and the floor wall 7.

Two inner partition plates 2 are placed opposite each other with an inner soundproof space 4 of approximately 60 mm in thickness, and the upper edge 2a and lower edge 2C of each inner partition plate 2 are circumscribed by the spacing holding frame 8 of each village. Depending on the situation, the inner partition plate 2 is formed so as to maintain a constant interval between the two doma.

Each outer partition plate 3 is placed on the outside of each inner partition plate 2 with each outer soundproof space 5 spaced apart, and the adjacent inner partition plate 2 and outer partition plate 3 are interposed between the side partition plates 2 and 3. They are joined by sandwiching the architectural bond 9.

Upper edges 2a, 3a, lower edges 2b, 3 of inner and outer partition plates 2, 3
B is airtightly joined to the ceiling wall 6 and floor wall 7 of the building by sandwiching architectural bond 10 that is continuously applied to the ceiling wall 6 and floor wall 7 of the building, thereby making each soundproof space 4.5 completely airtight, and simultaneously connecting the partition wall 1 and ceiling wall. 6 and the floor wall 7 to be completely airtight.

The spacing frames 8 of each upper and lower village are made of light-weight shaped steel having an angular cross-section and are spaced apart from each other in the left and right directions, and are attached continuously in the front and rear.

A rubber cushioning material 11 is interposed between the back surface of this shaped steel, the ceiling wall 6 and the floor wall 7, and the spacing frame 8 is fixed to the ceiling wall 6 and the floor wall 7 with bolts 12. The cushioning material 11 is formed so as to absorb the solid vibration from 7.

In addition, a thick cloth-like sound absorbing material 13 made of glass wool is folded into the inner surface of the upper and lower interval retaining frames 8 in a meandering manner, and is fixed to the interval retaining frames 8 by adhesive or other means. The sound propagating from the to the inner soundproof space 4 is absorbed.

As shown in Fig. 2, the joint of each partition plate 2, 3 is placed at the position of the architectural bond 9 that joins the inner and outer partition plates 2, 3, and there is a step between the edges of adjacent outer partition plates 3. If this occurs, before the architectural bond 9 hardens, a misalignment adjustment tool (for example, an awl) is inserted to restrain and harden it, thereby correcting the stepped portion.

In addition, when correcting unevenness on the plane of the outer partition plate 3 in areas other than the joints, it can be easily done by sticking a misalignment adjustment tool diagonally into the recess and curing it while the correction is floating. can.

Moreover, in this case, the upper and lower edges 3a and 3b of the outer partition plate 3 are not fixedly restrained to the ceiling wall 6 and the floor wall 7, so that the plane can be easily corrected.

The partition plates 2 and 3 are made of gypsum board with excellent sound insulation, fireproofing, and heat resistance, and the architectural bonds 9 and 10 are mainly composed of gypsum and bond, such as Yoshino Gypsum Tiger. Use GL bond (gypsum bond).

Note that the thickness of the partition wall 1 of the present invention is, for example, the thickness of the partition wall 1 of the present invention.
, 3 are respectively 9 mm and 12 mm, and the interior and exterior soundproof spaces 4
, 5 are respectively 60 mm and 12 mm, the total is 12
The thickness is 6 mm, which is only about 10% more than the conventional product's thickness of 117 mm, but the partition wall 1 has three layers of soundproof spaces 4 and 5 and is highly airtight, so it has excellent fire prevention performance. It becomes an excellent partition wall 1.

Note that the boundary between the side ends (not shown) of the partition wall 1 and pillar walls of the building, etc., has the same structure as the boundary between the ceiling wall 6 and the floor wall 7.

As a modification of the above embodiment of the present invention, a part thereof can be modified as follows.

1 As shown in Fig. 3, a thick cloth-like sound absorbing material 14 made of rock wool or glass wool is stretched at the middle position in the thickness direction of the inner soundproof space 4 to partition the inner soundproof space 4 into two layers. do.

The sound absorbing material 14 is fixed to the inner ear portions 15 of the upper and lower spacing frames 8 made of lightweight section steel.

This sound absorbing material 14 is for attenuating air vibrations of sound transmitted into the inner soundproof space 4 from the outside.

2 As shown in FIG. 4, the width of the upper spacing frame 8 is narrower than the width of the lower spacing frame 8, and the inner partition plate 2
is tilted inwards by about 2 degrees to improve the dispersion of sound transmitted from the outside into the inner soundproof space 4. Also, this sound is repeatedly reflected by the inner partition plate 2, and the sound is reflected by the upper sound absorbing material 13. Let it absorb.

Furthermore, by slanting the inner partition plate 2 in the shape of a sill, the construction bond interposed between the inner and outer partition plates 2 and 3 can be prevented from falling and can be properly fixed.

3. The cushioning material 11 in FIG. 1 is omitted, and each spacing holding frame 8 is directly fixed to the ceiling wall 6 and floor wall 7 with bolts 12, as shown in FIG.

Since the present invention is configured as described above, it has the following effects.

B Since the structure is such that the inner partition plate and the outer partition plate are joined with architectural bond across the outer soundproof space, the two joined partition plates have significantly increased rigidity and strength, and can be excited against the air vibrations of sound. It becomes difficult to do.

Further, due to the increased rigidity of the partition plate, the base crosspiece can be omitted, so that among the sounds transmitted through the partition wall, solid vibration propagation of sound between the inner partition plate and the earth floor can be blocked.

Moreover, there are two airtight outer soundproof spaces on both sides of the inner soundproof space.
layer increases, and the air vibrations of sound within this space are significantly attenuated.

Therefore, the sound insulation properties of the partition wall are significantly improved.

(b) The upper and lower ends of all internal and external partition walls can be easily and airtightly attached to ceiling walls and floor walls using architectural adhesive, and the outer partition plates can also be easily joined to the inner partition plates using architectural adhesive. be able to.

Furthermore, since both of the above operations can be performed in one process, the required man-hours can be significantly reduced, work efficiency is greatly increased, and
Moreover, the construction period can also be shortened.

C. There are two outer soundproof spaces on both sides of the inner soundproof space of the partition wall.
Since the inner soundproof space has an increased number of layers and there is no base crosspiece in the inner soundproof space, it is difficult for heat to transfer through the partition wall.Also, since the top and bottom of the partition wall are made airtight with bond, it is recommended to use partition plates made of fireproof material. If used, the fire protection performance of partition walls can be significantly improved.

2. The surface unevenness of the outer partition plate can be easily corrected by curing the concave portion in a raised state using a misalignment adjusting tool before the bond hardens.

Moreover, since the upper and lower ends of the partition plate are not constrained by the ceiling wall and floor wall at this time, correction is easy.

Therefore, since the appearance of the partition wall can be finished neatly, the commercial value of the partition wall can be increased.

(e) When the inner partition plate is slightly inclined inwards, the construction bond does not fall and is easily fixed when placing the bond between the inner and outer partition plates, improving work efficiency.
