Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 This invention is a soundproof wall that is erected on the roadside of a road or a railroad, and in particular, struts are erected at predetermined intervals along the roadside, and a soundproof wall made of a hard synthetic resin plate or a metal plate between adjacent stanchions. The present invention relates to a soundproof wall configured by attaching a plate.

[0002]

[Prior art]

 Conventionally, on-site construction of this type of noise barrier is roughly divided into the following three methods. [1] The first is a bolt-type construction method. As shown in FIG. 8, a synthetic resin soundproof plate (110) prepared in advance and an attachment frame member (also called reinforcement) 111) and (112) are carried into the site, the columns (113) are aligned on the site, and the required mounting holes (114) are drilled in them, and then the columns (113) made of H-shaped steel or the like. ), The soundproof plate (110) is attached and fixed together with the mounting frame members (111) and (112) with bolts and nuts (115).

[2] The second is a construction method called a fitting method, and as shown in FIG. 9, it is sandwiched between the peripheral frame members (121) and (122) prepared in advance, and the soundproofing is performed. This is a method of fixing the plate (110) to the facing surface of the adjacent column (123) with the bolt (116).

[3] A third type is called a drop-in type, and as shown in FIG. 10, a peripheral frame member (131) is integrally attached and fixed to the peripheral edge of the soundproof plate (110) in advance. After making a soundproof panel (130) with a frame, at the construction site, drop the soundproof panel (130) from between the adjacent columns (133) made of H-shaped steel from above, and then between the H-shaped steel and the soundproof panel. This is a construction method in which a soundproof panel (130) is fixed by inserting an appropriate steady rest (not shown) or the like.

[0005]

[Problems to be solved by the device]

 However, in both of the construction methods [1] and [2] above, the soundproof plate (110) is attached to the columns (113) and (123) while performing the alignment on site, so that the operator There is a problem that it requires a certain amount of skill and requires a relatively large amount of labor and time to perform on-site work, which requires a long construction period. Furthermore, in the construction method of [1], the mounting frame members (111), (112) and the soundproof plate (110) are projected from the H-shaped column (113), and an extra width is added to the road width. There was a necessary problem. Further, in the construction method of the above [3], there is a problem that it is difficult to insert the steadying metal fixture and fix it at a predetermined position, the work is time-consuming and the construction period is not necessarily shortened. In particular, the above-mentioned construction methods [1], [2], and [3] require work such as bolt tightening and insertion of steady rests from the back side, and it is extremely time-consuming to work on viaducts that are difficult to work from the back side. However, there is a problem that it is difficult to respond to the recent strong demand for shortening the construction period on site.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a panel with a frame by preliminarily attaching peripheral frame members of upper and lower frame bodies and side frame bodies to a soundproof plate at the factory. A spring member is attached to at least the lower end portion of the upper and lower end portions, and the spring member is fixed to the peripheral frame member by forming a height a little wider than the gap between the H-shaped column piece and the peripheral frame member. A soundproof panel is constructed, and at the construction site, at least the lower end of the soundproof panel can be positioned and fixed to the column by inserting the soundproof panel from above. This eliminates the need to fix and support the lower end of the soundproof panel from the back side. The upper end portion of the peripheral frame member may be positioned and fixed by a spring member like the lower end portion. In this case, it is possible to prevent rattling and sound generation due to vibrations and the like, and it is possible to form a soundproof wall to which a soundproof panel can be easily attached between the columns by simply inserting the peripheral frame material. When positioning and fixing the upper end of the peripheral frame material by adjusting the length of the bolt instead of using a spring member, vibration is suddenly attacked by the spring in the lower part and the upper part is positioned and fixed, ensuring sound insulation. A soundproof wall can be formed by attaching panels between columns. For the soundproof plate, an acrylic plate, a polycarbonate resin plate or the like is preferably used because it has excellent impact resistance, weather resistance and transparency. For the peripheral frame material attached to the peripheral edge of the soundproof plate, a commonly used member is mainly used to supplement the bending strength of the soundproof plate. In this way, the on-site work can be simplified and the construction period can be greatly shortened.
