Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a soundproof wall which is erected on an elevated road, a road shoulder, a side road, or the like.

<Prior Art> On elevated roads and railroads, the noise generated when the vehicle is running has been polluted, and it is widely practiced to install a predetermined soundproof wall on the shoulders or side roads to prevent noise. ing.

Various means have been used to erect the soundproof wall. For example, there is a method of placing concrete between the predetermined assembled mold plates.

However, in this case, the reinforcing bars must be knitted in advance between the template plates, which requires a cost and a construction period, and further has a problem that the weight is increased.

Further, there is also one in which H-shaped steels are erected at appropriate intervals and a pair of plate members are fitted between the H-shaped steels.

However, also in this case, it takes a lot of time to set up the H-shaped steel, and there remains a problem in the strength of the plate materials against wind and rain, and although the space between the plate materials becomes almost airtight, rainwater may enter and accumulate. , There was an inconvenience.

<Problems to be solved by the invention> In this type of soundproof wall, it is first required to surely shield noise, but in order to reduce the load on the road surface or bridge girder, it is necessary to reduce it as much as possible. It is required to be lightweight, and it must have durability against wind and rain, and must have rust resistance against sea breeze.

<Means for Solving the Problem> The present invention has been devised to solve the above-mentioned problems and meet the requirements, and includes a first wall plate member and a second wall plate member each having a plurality of vertical partition parts formed on one surface. In the state in which the wall material is composed of the wall board material and both wall board materials are joined so as to overlap with each other, the partition parts of the wall board materials collide with each other and the upper and lower ends are opened inside the wall material in the vertical direction. A plurality of spaces are formed, the upper and lower ends and side surfaces of the space portions located on the left and right side edges of the wall material are open, and when the wall materials are installed upright from the road surface in parallel, the side edges of the adjacent wall materials are Each space part continuously forms a vertical empty part,
This is a soundproof wall that is erected by arranging an anchor streak upright from the road surface in the empty space and supplying a filling material to the empty space to cure it.

<Operation> Since the present invention has the above-described configuration, the first wall plate material and the second wall plate material are simply joined so as to be polymerized to form the wall material,
With the wall materials standing upright from the road surface and arranged in parallel, insert an anchor bar that stands upright from the road surface from below into the empty part of the side edge of the adjacent wall material, and supply the filling material to this empty part. It can be installed simply by curing.

In this case, the filler hardened in the void portion not only serves as a pillar for connecting the adjacent wall materials, but also has an effect of connecting the wall material and the road surface by the anchor streak.

The wall member is composed of the first wall plate member and the second wall plate member, and a plurality of vertical space portions are formed, so that this space portion functions to absorb noise.

Further, since the filler is supplied to the connecting portion of the adjacent wall materials, noise and rainwater will not leak to the outside through the connection gap.

Furthermore, since the partition parts of the first wall plate member and the second wall plate member are in abutment with each other, the wall member has sufficient strength against wind and rain.

<Example> Hereinafter, the present invention will be described with reference to the drawings of an example.

The wall material 1 in the present invention is composed of a flat plate-shaped first wall plate material 2 and a second wall plate material 3 made of a concrete material.

On one side of the first wall plate member 2 or the second wall plate member 3,
A plurality of vertical partition parts 4 are formed, and both wall plate materials 2,
In a state in which the wall material 1 is formed by superposing 3 to be superposed, the partition portions 4 of the wall plate materials 2 and 3 collide with each other, and the upper and lower end portions are opened inside the wall material 1 in the vertical direction. A plurality of space portions 6 are configured.

In the embodiment shown in FIGS. 1 to 4, a plurality of partition portions 4 are formed in a rib shape in the vertical direction and are formed so as not to be located at the left and right side ends of the wall plate members 2 and 3, and as a result, the wall member 1 is formed. Space portions 6 are formed at the left and right side ends of the space portion 6.

The space portions 6 located at the left and right side ends of the wall material 1 have their upper and lower ends and side surfaces open, and when the wall materials 1 are installed upright from the road surface 12 in parallel, the side walls of adjacent wall materials 1 are The space portions 6 at the ends are continuous to form a void portion 7 in the vertical direction.

Then, the anchor streak 11 that stands upright from the road surface 12 in this empty portion 7
Is inserted from below, and a filling material 8 such as a concrete material is supplied to this empty portion 7.

Since the wall material 1 is made of a concrete material,
It is extremely compatible with the filler 8 such as concrete material, and when the filler 8 is cured and hardened, it can be firmly integrated.

The anchor streak 11 is substantially L-shaped, the lower part thereof is embedded in the road surface 12 in advance, and the protruding installation intervals of the upper part of the anchor streak 11 are formed at the side ends of the adjacent wall materials 1. Alignment is easily achieved by corresponding to 7.

The road surface 12 is an elevated type supported by a bridge girder 13.

If necessary, the upper end opening of the wall member 1 may be covered with a cover plate 9 to prevent rainwater from entering, and the drain holes 5 may be formed in the lower portions of the wall plate members 2 and 3.

Furthermore, a plate-shaped shield plate 10 formed of a concrete material may be provided at the lower end of the space 6 of the wall material 1. The shielding plate 10 is for filling the gap between the lower end of the wall material 1 and the road surface 12, and prevents noise and rainwater from leaking to the outside.

Next, FIG. 5 shows another embodiment of the wall member 1, in which the wall plate members 2 and 3 are formed into a corrugated plate shape, and the mountain portions of the wall plate members 2 and 3 facing each other are close to each other. Is defined as a vertical partition portion 4, and these mountain portions are fixed to each other by a fastener such as a bolt.

Although the present invention has been described with reference to the embodiments of the drawings, the present invention is not limited to the above-described embodiments and can be carried out in any manner without changing the configuration described in the claims.

<Effects of the Invention> In short, according to the present invention, a wall material is simply formed by superposing a pair of wall plate materials so as to overlap each other, and the wall materials are installed upright from the road surface in parallel at a predetermined position. It can be installed simply by inserting the anchor bar from below and supplying the filling material, so construction at the site is extremely easy, and the construction cost and construction period are also small.

Further, the filling material serves as a strong pillar that surely connects the adjacent wall materials, and also achieves the connection between the wall material and the road surface by the anchor streak.

And since the wall material can absorb noise in the space and is lightweight because it is hollow, there is no demand for increasing the strength of the road surface or bridge girder more than necessary, and the filler material prevents the wall material from adjoining walls. Prevents noise and rainwater from leaking to the outside from the gaps between the connecting parts of the material, and furthermore, since the partition parts of the first wall plate material and the second wall plate material are abutted against each other, the wall material is abutted against each other. Also, the strength against wind and rain becomes sufficient, the constituent materials are simple, and the mass production is possible at low cost, which is of high practical value.
