Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a joint material with good sound insulation properties and workability, which is used in joints of partition panels and the like in buildings.

(Prior Art) Generally, gaps are provided in the joints of architectural panels in order to accommodate deformation of the vibration damping structure and frame of high-rise buildings.

Conventionally, in order to prevent sound and heat from escaping through this gap, a joint structure in which the gap is filled with caulking material has been widely adopted.

(Problem to be solved by the invention) However, the above-mentioned conventional filling with caulking material
Workability, sound insulation, and heat insulation properties were inadequate.

In other words, if high sound insulation is required,
It was necessary to fill the sound insulating material and filler in multiple layers. Further, it takes time for the caulking material to solidify, and as the width and depth of the joint increases, a large amount of caulking material is required, which increases both cost and construction time, which is undesirable. In addition, it may be difficult to fill caulking material into corners and the like. Further, the caulking material may not be in close contact with the end face of the panel at the joint portion, and in that case, the sound insulation properties are significantly reduced. Further, since the caulking material has poor heat insulating properties, there is a problem in that dew condensation occurs only in the joints, causing staining and peeling.

The present invention was devised to solve these problems, and the object is to provide a new sound-insulating joint material that has excellent workability and heat-insulating properties as well as sound-insulating properties.

(Means for solving the problem) In order to achieve the above object, the solution of the present invention is a long body formed in a long shape as a sound insulating joint material, at least the front and back layers of which have a specific gravity. It is made of a sound insulating sheet with a diameter of 1.6 or higher, and the inside thereof is made of a porous elastic material.

(Function) With the above configuration, the present invention deforms the long sound insulating joint material in the gap (joint) of the joint part of the construction panel using the elastic deformation action of the porous elastic body. By fitting the sound insulating sheet to the end surface of the panel, the sound insulating sheet can be pressed against the end surface of the panel by the elastic restoring action of the porous elastic body, and can be inserted into a state in close contact with the end surface of the panel. In that case, a multiple sound insulation structure is formed by at least two layers of sound insulation sheets, sound is attenuated by a porous elastic material between the sound insulation sheets, and the sound insulation sheet is airtightly adhered to the end surface of the panel as described above. This will significantly improve sound insulation.

In addition, even if the width or depth of the joint is large or in a narrow space such as a corner, it can be easily inserted by simply fitting it, and has excellent workability.

Furthermore, since the porous elastic material has good heat insulation properties, dew condensation does not occur at the joints.

The sound insulating joint material A ₆ of the sixth embodiment shown in the figure is a modification of the sound insulating joint material A ₄ of the fourth embodiment described above, in which the sound insulating sheet 1 on the surface layer is extended to both sides, and fins extending in the longitudinal direction are formed. The fin-shaped protrusions 4, 4 are integrally provided, and the fin-shaped protrusions 4, 4 improve the adhesion to the panel end surface when the sound insulating joint materials _A5 , _A6 are inserted into the joints. It was designed to increase the

Here, the sound insulation sheet 1 is a sheet formed by filling or laminating an inorganic filler, metal powder, or metal foil into a synthetic resin such as PVC, polyethylene, natural rubber, synthetic rubber, asphalt, etc. A body with a density of 1.6 g/cm ² or more. The porous elastic body 2 may be a synthetic resin foam such as urethane, polyethylene, or PVC, or may be a fiber mat-like material made of glass wool, rock wool, etc., as long as it has a certain degree of restorability. As a method of forming a sound insulation joint material using such a sound insulation sheet 1 and a porous elastic body 2, as described above, the porous elastic body 2 is laminated or injected into a sound insulation sheet 1. In addition, it also includes a porous elastic body 2 that has been formed in advance and is integrally coated with a sound insulating material by gel coating the outer periphery thereof.

Next, the sound insulating joint material A ₁ to

The construction status of A ₄ is shown.

That is, sound insulating joint materials A ₁ to A ₆ are applied to the gaps (joints) 6 at the joints of the architectural panels 5, 5.
By deforming and fitting using the elastic deformation action of the porous elastic body 2, the sound insulating joint material A ₁ ~
A ₆ is inserted into the joint 6 in a deformed state.
In that case, the sound insulating joint materials A ₁ to _{A 6} in the joint 6 are in a state in which the sound insulating sheet 1 is pressed against the end surface of the panel 5 due to the elastic restoring action of the porous elastic body 2 and in close contact with the end surface of the panel 5. airtightness can be improved. In addition to this improvement in airtightness, the synergistic effect of the multi-layered sound insulation structure with at least two layers of sound insulation sheets 1 and the attenuation of sound by the porous elastic body 2 between the sound insulation sheets 1 and 1 improves sound insulation. It is possible to significantly improve the sound insulation performance of joints, and it is possible to demonstrate excellent sound insulation performance at joint areas. In particular, in the case where the fin-like protrusions 4, 4 are provided as in the fifth and sixth embodiments, the adhesion to the end face of the panel 5 and the airtightness are further improved, so it is possible to further improve the sound insulation performance. can.

In addition, even if the width or depth of the joint 6 is large, or if high sound insulation is required, it can be easily handled by inserting two or more pieces of sound insulation joint material A ₃ in the depth direction, for example, as shown in Figure 8. In addition, it can be easily inserted even in narrow spaces such as corners, so it is easy to insert and has excellent workability. Moreover, when finishing as shown in Fig. 8, and after fitting sound insulating joint material A ₁ as shown in Fig. 7, putty 7 is applied.
In the case of filling in the holes, the construction period can be shortened by simply fitting both sides, and it is simple and requires no special skills, which is advantageous in terms of construction period and cost.

Furthermore, since the porous elastic body 2 of the above-mentioned sound insulating joint materials A ₁ to _{A 6} has heat insulating properties, good heat insulating properties are ensured at the joints (joints) and the occurrence of dew condensation at the joints is prevented. As a result, it is possible to prevent staining and peeling of joint areas, and improve appearance and durability.

(Effects of the invention) As explained above, according to the sound insulating joint material of the invention, it can be easily inserted into gaps (joints) between joints of architectural panels in a short construction period, regardless of the size of the joint or its location. In addition, the sound insulation properties can be significantly improved due to the multiple sound insulation structure of the sound insulation sheet, the sound attenuation property due to the porous elastic material, the close contact of the sound insulation sheet to the panel edge surface, and the airtightness. It is possible to provide a joint material that has excellent sound insulation properties, heat insulation properties, and workability, such as no dew condensation at the joints.
