Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a sound insulation wall for insulating traffic noise and the like, and more particularly to a method of using wood to make the surface appearance melt into a natural environment and to make effective use of wood. It is.

[0002]

2. Description of the Related Art Conventionally, concrete panels, metal panels, plastic panels and the like have been used as sound insulation walls for blocking traffic noise. Artificial objects such as tasteless concrete and metal were exposed to the outside on the surface, and it was obvious that the structure was an artificial structure, and the landscape was damaged.

Therefore, it has been proposed to use wood instead of concrete or metal structural materials for the sound insulation wall. By stacking logs, it has a sound-insulating wall function, and it is made of wood so that viewers do not feel that it is an artificial structure.

[0004]

However, a single-layer wood panel does not have sufficient sound insulation. Therefore, it is an object of the present invention to provide a construction method for improving the sound insulation of a sound insulation panel. Further, wood alone is not sufficient in strength, and it is necessary to withstand collision of an automobile.

[0005]

SUMMARY OF THE INVENTION The present invention is to improve the sound insulation of a wooden sound-insulating wall by mounting wooden panels in which log materials are stacked in parallel on a column and forming a space between the wooden panels. . Further, this space is filled with a sound absorbing material to enhance the sound insulating effect. Further, by interposing a large mass such as a concrete panel between the wooden panels, the sound insulation performance can be improved and the strength of the completed wooden sound insulation wall can be increased.

[0006]

[Function] The appearance of the sound insulation wall made of wood gives people a soft feeling different from concrete or metal sound insulation walls, and the noise is reflected in multiple directions due to the naturally formed irregularities on the surface of the wood. Scattered and the noise is attenuated. An air layer in the space between the juxtaposed wooden panels blocks transmission of sound waves. When the space is filled with a sound absorbing material or a large plate such as a concrete plate is interposed, the sound insulation is further improved. By fixing the concrete plate to the foundation, the strength of the sound insulating wall is increased, and it becomes possible to withstand a collision of a car or the like. Then, by using the panel of the present invention, a panel that matches the natural environment can be constructed easily and at low cost. In addition, the wooden panels can be easily replaced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. Example 1 FIG. 1 shows a cross-sectional view of a sound insulation wall using a wooden panel of the present invention. The wooden panel 1 is obtained by cutting logs, preferably thinned wood, and making upper and lower planes overlap each other, making a hole penetrating vertically, making a hole in a reinforcing steel bar, a PC steel wire, a carbon fiber stranded wire, and a glass fiber. Using a stranded wire or the like, the upper and lower ends are tightened with wedges or bolts using an anchor plate to integrate the log into a panel. The size of the wooden panel 1 is appropriately determined in consideration of workability and ease of handling.

In addition, one unit of about three logs is unitized with a fixing bracket on the rear side, and holes are provided vertically through the upper and lower parts. Becomes easier.

The construction method of the present invention will be described. First, the column 2 of H steel is fixed to the foundation F. A groove 11 for accommodating an H-steel flange 22 is provided at a side end of the wooden panel 1 prepared in advance, and the groove 11 is fitted to the H-steel flange 22. If the depth of the groove 11 is set so as to cover half of the flange of the H-steel, which is the support 2, the flange surface can be entirely covered with wood so that it is not exposed when the sound insulation wall is completed.

A plastic channel (not shown) having a groove-shaped cross section is fitted into the groove 11 so that the wooden panel 1 can be smoothly attached to the column 2. The groove 11 is filled with a sealant to make it waterproof, so that the column 2 does not rust. Another wooden panel 1 is connected to another flange 22.
, The two wooden panels 1, 1 are arranged in parallel, and a space 3 is formed between them.

A roof panel 4 made of a log material that covers the upper part of the sound insulation wall is placed on the upper surfaces of the wooden panels 1 and 1 arranged in parallel, and the upper part is covered and fixed with an adhesive or bolts. The joint is filled with a sealant 41 and sealed to prevent rainwater from entering the H steel of the column.

Example 2 After attaching a wooden panel 1 to a support 2 in the same manner as in Example 1, a sound absorbing material 5 such as glass wool is provided on the inner side of the wooden panel.
Is fixed with nails or the like, and the other wooden panel 1 is attached.
Since the sound absorbing material 5 is provided in the space as shown in FIG. 2, the propagation of noise outside the road can be reduced. Further, a roof panel 4 made of a log material is placed and fixed on the upper part of the sound insulating wall, and the joint is sealed. In order to prevent rainwater from penetrating from the joint of the log of the roof panel 4, the joint of the log and the log is sealed in advance. As a method of sealing, a rubber packing is attached in advance to a portion of the sound insulating wall in contact with the wooden panel at the time of manufacturing the roof panel 4, or a sealant 4 is installed at the time of installing the roof panel 4.
1 is applied and filled in the joint.

Embodiment 3 A wooden panel 1 is attached to a column 2. A sound insulating plate 6 made of concrete with sound absorbing materials 5 stuck on both sides is installed in a space 3. The urethane foam 7 is set on the H steel web of the support 2, and the sound insulating plate 6 is pressed and deformed.
A sound insulation board will be installed between columns. Then, another wooden panel 1 is attached to the column 2, and then the roof panel 4 is attached to the upper part of the sound insulating wall.

The wooden panels 1, 1 on both sides are attached to the columns 2. Reinforcing bars are buried in the foundation in advance, and holes through which the reinforcing bars penetrate are provided in a concrete plate serving as a sound insulating plate. Drop it into space 3 through a reinforcing bar through the hole in the concrete plate,
The concrete plate is fixed to the foundation by pouring grout into the holes. As another fixing method, a PC steel rod or a PC steel strand is embedded and fixed on a foundation, and a concrete plate is fixed by applying prestress.

Urethane foam or sponge may be attached to both sides of the sound insulating plate 6 in advance to attenuate sound waves propagating to the support. The sound insulating plate 6 is preferably made of concrete from the viewpoint of cost, but is not limited to this, and may be any material that blocks propagation of sound waves.
The material is selected in consideration of cost and the like.

When used in combination with not only a sound insulating plate but also a sound absorbing material, the sound insulating performance can be enhanced. By fixing the sound insulating plate to the foundation, the strength of the sound insulating wall is increased, and it becomes possible to withstand a collision of an automobile or the like.

[0017]

According to the construction method of the present invention, a wooden panel in which log materials are laminated is used as a sound insulation wall so that materials such as metal are not exposed on the surface, so that the appearance is not so much felt as an artificial structure. In addition to providing a space, a sound absorbing material or a sound insulating material, or a combination of a sound insulating material and a sound absorbing material, can improve the sound insulating performance. By fixing the sound insulating plate to the foundation, the strength of the sound insulating wall has been increased, and it has become possible to withstand a collision of an automobile or the like.
