BACKGROUND OF THE INVENTION
The present invention relates to a sound insulation plate that is installed on the side of a highway, for example, to insulate automobile noise and the like, and more specifically, a pair of sound insulation plate mounting posts arranged at intervals in the lateral direction. A frame-like frame body that can be installed in a fitted state is provided, and a sound insulation thin plate that can be attached to the frame body (for example, a polycarbonate or acrylic thin plate) is provided. The present invention relates to a sound insulating plate in which a pair of penetrating portions through which a pair of fixed sound insulating plate fall prevention cords are passed are provided in the frame body.
[0002]
[Prior art]
Conventionally, as this type of sound insulation plate, as shown in FIG. 7, a pair of sound insulation plate fall prevention cords (hereinafter simply referred to as vertical arrangement cords) that are individually penetrated through the pair of penetration portions 20 respectively. There is a structure in which a second cord 21 for preventing sound insulation plate dropping (hereinafter simply referred to as a laterally arranged cord) 21 connected to R is provided in the frame 22 in a state along the interval direction of the both struts 1. In the state in which the sound insulation plate is disposed between both struts 1, both end portions of the laterally arranged cable bodies 21 are connected to the vertically arranged cable bodies R penetrating the frame body 22. For example, even when an automobile collides with the sound insulation board and breaks the sound insulation board, the sound insulation board falls due to the vertically arranged cable body R and the laterally arranged cable body 21 penetrated inside. There was something that could prevent this. (For example, see Japanese Patent Laid-Open No. 3-191106)
[0003]
[Problems to be solved by the invention]
According to the above-described conventional sound insulation board, the both ends of the laterally arranged cable body 21 are installed in a state of being connected to the pair of vertically arranged cable bodies R, respectively. Are supported by the pair of vertically arranged strips R at both ends. Therefore, for example, when the automobile collides with a state where it breaks through the sound insulation board, the laterally arranged striated body 21 counteracts the tensile strength against the force from the automobile. Thus, the force from the automobile acts on both longitudinally arranged cords R via the laterally arranged cords 21. After all, as the force from the automobile is larger than the strength of the laterally arranged / vertically arranged striated bodies, the sound insulating plate alone is not damaged. There is also a risk of adversely affecting the structure provided with the support.
That is, according to the conventional sound insulation plate, in order to achieve the fall prevention of the sound insulation plate, a considerably strong strength member (each cable body, support column, and each connection member thereof) is used, and a large scale is required. There is a problem in that it is necessary to provide a support structure, and the efficiency of the sound insulation plate mounting operation is low, and the aesthetics are easily impaired.
[0004]
Accordingly, an object of the present invention is to provide a sound insulating plate that can solve the above-mentioned problems, can be easily attached while preventing the sound insulating plate from falling, and can easily improve aesthetics.
[0005]
[Means for Solving the Problems]
〔Constitution〕
According to a first aspect of the present invention, there is provided a frame-like frame body that can be installed in a state of being fitted between a pair of sound insulation plate mounting columns arranged at intervals in the lateral direction. A pair of vertical frame portions arranged along the vertical frame portions and a horizontal frame portion provided across the vertical frame portions, and a pair of sound insulation plate fall prevention cords fixed separately along the both columns. In one end portion of the horizontal frame portion, a separation allowing means for allowing separation between the cord body penetrating through a pair of penetration portions formed in the frame body in a state of penetrating and the horizontal frame portion is provided. There is.
[0006]
The characteristic configuration of the present invention according to claim 2 resides in that the separation allowing means is formed by a notch in which a penetrating portion formed in the horizontal frame portion is opened along the separation direction.
[0007]
[Action and effect]
According to the characteristic configuration of the present invention according to claim 1, the frame-shaped frame body includes a pair of vertical frame portions and horizontal frame portions, and penetrates through the pair of through portions formed in the frame body. In the one end portion of the horizontal frame portion provided with the separation allowance means, the separation permission means for allowing separation between the strip body and the horizontal frame portion is provided at one end portion of the horizontal frame portion. The horizontal frame portion can be separated from the striated body positioned on the fixed side. Therefore, for example, when an automobile or the like collides with the sound insulation plate and the impact force acts on the sound insulation plate, the lateral frame portion is separated from the cord body at one end portion thereof and is supported at the other end portion. It is possible to avoid the force due to the collision acting properly by moving around the striated body. And even if a sound insulation board remove | deviates from the said support | pillar, since a horizontal frame part is supported by a cable body in the other end part, it can prevent falling.
As a result, it is possible to prevent a large member force from acting on the sound insulating plate, the above-mentioned cable body, the support column, and their connecting members, and to set the strength of each member to the minimum necessary level. As a result, the range of materials can be expanded, and it is possible to construct an appearance with a rich aesthetic rather than a rugged design. For example, it is possible to use a light-weight material that is generally considered to have low strength. As a result, it is possible to smoothly perform the mounting operation of the sound insulating plate and improve the working efficiency.
Furthermore, by making the frame body smart, it is possible to increase the opening area of the frame body. For example, when a translucent plate is used as a thin plate, it becomes easier to secure a field of view.
[0008]
According to the characteristic configuration of the present invention according to claim 2, the separation allowing means is constituted by a notch in which a penetrating portion formed in the horizontal frame portion is opened along the separation direction. It is possible to form a sound insulating plate that achieves the above-described effects, and it is possible to prevent an increase in cost.
