Description

  The present invention relates to a method for installing a decorative panel on a reinforced soil wall slope. More specifically, the present invention relates to a method for installing a decorative panel on a reinforced soil wall slope using a mesh wall material.

  In the embankment formation method, a construction method is known in which a slope is formed by stacking metal molds that are substantially L-shaped when viewed from the side at the slope position and stacked in contact with each other in the vertical direction. A planar reinforcing material such as geotextile is used in combination with a frame (for example, Patent Document 1). As the L-shaped formwork, an L-shaped formwork is used in which a steel wire mesh is stretched on the formwork, and the L-shaped formwork is stacked in multiple stages while rolling the embankment surface to form a slope. This method is also used for the construction of vertical slopes and steep slopes. Since the embankment material constructed by such a construction method has an embankment material exposed on the surface, it is required to deal with it when emphasizing the landscape.

As a method of constructing the retaining wall provided to stabilize the slope of the embankment, when embedding, horizontal reinforcing materials embedded in the embankment are connected to each other with steel connecting materials, which are sequentially stacked and reinforced in the vertical direction. A construction method for constructing a soil retaining wall is known, but the wall of the reinforced soil retaining wall is made of a block material due to earth pressure. Therefore, the block material is first installed, the planar reinforcing material is connected to the block material at a distance from the block material, and the substantially L-shaped formwork is installed on the planar reinforcing material laid in the horizontal direction. A method of constructing a reinforced earth retaining wall by repeating the process of embanking and filling a granular drainage material between a block material and a formwork has been proposed (Patent Document 2).
In this construction method, the exterior is covered with block material, so there is an effect of maintaining the scenery for the time being, but in order to stack heavy block material, construction with heavy equipment such as cranes is necessary and at the same time, this heavy block material does not fall off It is necessary to firmly connect the surface reinforcing material to the block material, and there is concern about blockage of the block material due to consolidation settlement of the embankment material or earthquakes, but it is easy even if the block material is deteriorated or damaged It cannot be replaced.

  In addition, using a frame with a reinforcing sheet fixed to one end to form the embankment slope, drainage material is thrown into the frame side end, and then a plurality of layers formed by depositing the embankment material are constructed. A method has been proposed in which a mold frame is attached to the slope surface side of the slope surface via a stretchable spacer rod, and a retaining wall is constructed on the side surface of the embankment by placing concrete between the mold frame and the frame (Patent Document 3). ). This method ensures the drainage of the embankment, but there is concern about deformation and damage of the concrete retaining wall due to consolidation settlement of the embankment material, earthquakes, etc., but it is not easy to repair the retaining wall.

It can be seen that the rod-shaped member 3 that gives resistance is designed so that a portion far in the direction of the normal surface faces vertically upward.

  The decorative panel mounting member of the present invention is provided with long holes that are long in the vertical direction so as to be joined to the plurality of rod-shaped connecting members. The decorative panel mounting member is composed of a member provided with a long hole in the vertical direction to be joined to the rod-shaped connecting member, and a member for mounting the decorative panel. The member to be joined to the rod-shaped connecting member is parallel to the direction of the rod-shaped connecting member, and the member to which the decorative panel is attached is parallel to the decorative panel to be normally attached. Therefore, the decorative panel attaching member is L-shaped or T-shaped in sectional view. It is preferable that

Since the decorative panel mounting member and the rod-shaped connecting member are joined using both long holes, it is possible to adjust up, down, left and right, so changes due to subsidence during construction and deformation such as subsidence after construction is completed Therefore, the influence on the decorative panel to be installed can be reduced.
Although there is no restriction | limiting in particular in the joining method of a decorative panel attachment member and a rod-shaped connection member, The screwing by a volt | bolt, a nut, etc. can be mentioned as a simple example.

  It is preferable that the decorative panel mounting member is set so as to be joined to a predetermined number of bar-shaped connecting members when the bar-shaped connecting members are embedded corresponding to the respective wall surface materials. The predetermined number is about 2 to 4, preferably 2. For example, if the structure is separated in the height direction by being joined to a two-stage rod-shaped connecting member, the influence on the panel can be reduced even when deformation such as subsidence occurs after the completion of construction.
