Description

  The present invention is a formwork structure for forming a concrete wall of a concrete wall or other building that divides a side road and a roadway in a tunnel, and a decorative plate member such as a large and thin stone or tile is provided. The present invention also relates to a formwork structure that also serves as a plate and serves as a plate member for makeup that also completes the makeup of the wall at the same time as the concrete wall.

  There exists an example of patent document 1 in the formwork structure which also serves as a plate member for makeup | decoration. This is a wall construction method using a stone material that uses a stone material that also serves as a surface finish material as a mold on the front side when constructing a wall or a wall by placing concrete in a formwork after placing reinforcing bars It is.

  More specifically, a stone plate having a relatively thick skin, for example, a thickness of about 4 cm, is used on the front side, and a temporary form frame such as veneer plywood or an inexpensive thickness of about 2 cm is used on the back side. Stone panels. In both cases, dowel holes are opened in the upper and lower ends, and when a stone plate or stone panel is stacked up and down, the upper and lower dowel holes are filled with adhesive, and a common stainless steel rod is inserted to connect the upper and lower sides. . At this time, in order to maintain the distance between the stone plate on the front side and the stone panel on the back side, a common connecting metal plate is interposed between the corresponding upper and lower stone plates and the upper and lower stone panels.

  In the vicinity of both ends of the metal plate for connection, holes corresponding to the dowel holes of the stone plate and the stone panel are respectively opened, and the stainless steel rods pass through these holes, and the upper and lower portions thereof are the upper and lower stone plates, respectively. Or it can be inserted into a dowel hole in a stone panel. Further, another hole is also opened at a predetermined position near the inside of the connecting metal plate so that the anchor line raised from the foundation can be penetrated.

  The concrete is cast after building the formwork in the height direction or after completing the construction of the formwork between the stone plate that also serves as the formwork on the front side and the stone panel on the rear side thus constructed. . In addition, the temporary form frame which used the general veneer plywood etc. is used for the both ends of a fence or a wall, and after placing concrete as mentioned above, a cap stone is mounted. Dowel holes are opened in the lower part on both sides of the crust, and the dowel hole, the stone plate and the dowel hole at the upper end of the stone panel are filled with adhesive in the same manner as described above, and the metal plate is interposed between them. Above, the hole is penetrated, and the upper and lower portions of the stainless steel rod are inserted into the dowel holes of the stone plate and stone panel and the dowel holes of the lower portion of the capstone.

  After the concrete is hardened, if the temporary formwork such as veneer plywood at both ends is removed, the ridge or wall is completed.

  According to the wall construction method using the stone material of this patent document 1, construction is easy, and the obtained fence or wall is said to have sufficient seismic resistance because it contains reinforcing bars. Also, according to this construction method, the completion of the wall is completed at the same time as the completion of the wall, and at least the front side does not use a temporary form frame such as a veneer plywood, so that the removal work is unnecessary and the veneer plywood There is no loss due to consumption.

  However, according to the wall construction method using the stone material of Patent Document 1, the front stone plate and the rear stone plate are simply connected to each other with a stainless steel bar through a dowel hole, and the distance between the two is also connected. It is only held by a hardware plate. Therefore, when placing concrete in the meantime, there is a possibility that the stone plate and the stone panel may be damaged by the load of the concrete from the inside. In particular, since the upper and lower ends thereof are supported only by the stainless steel rod inserted into the dowel hole, there is a possibility that the load is concentrated on the portion of the dowel hole where the stainless steel rod comes into contact, and this portion may be damaged.

  Furthermore, even if there is no damage when placing concrete on the stone plate or stone plate, it is possible that the stone plate or stone plate and concrete will peel off due to earthquakes or other vibrations. In this case, the stone plate or stone plate is supported only by the stainless steel rod inserted into the dowel hole. When this happens, the stone plate and the stone panel are likely to be damaged around the dowel hole due to the subsequent movement due to vibration such as an earthquake or wind pressure, and the stone plate or the stone material due to the damage. There is also a risk of panel peeling.

  Related technologies other than the above-mentioned Patent Literature 1 include Patent Literatures 2 and 3 and the like. However, these are not technologies that use a stone for makeup also as a formwork, but concrete for buildings. The panel member for thermal insulation that is stretched on the outer surface of the wall is constructed so that it can be used as a formwork for constructing the concrete wall. The stone or the like is attached to the outside of the panel member through some means.
