Description

  The present invention relates to an SC wall panel inner conduit mounting method and an SC wall panel inner conduit mounting structure in which a conduit embedded in an SC structure wall is passed through and fixed to an SC steel plate.

  In recent years, for example, an SC (steel concrete) structure has been increasingly applied in place of an RC (steel reinforced concrete) structure for a wall structure of a power plant building or the like. The SC wall is configured by installing a plurality of steel plates provided with studs in such a manner that the surfaces on the stud side face each other, and placing concrete between the steel plates.

  When attaching a conduit to such an SC wall, conventionally, a duct is disposed along the inner surface of a steel plate constituting the SC wall (hereinafter referred to as “SC wall panel”), and a metal made through the duct is inserted. There is known a construction method in which a flexible conduit is connected to the tip of the conduit, the flexible conduit is passed through a through hole formed in the SC wall panel, and led to the opening on the panel outer surface side (for example, Patent Document 1).

  In addition, the connection box element of the conduit is attached to the unit panel divided into a plurality, and the connection box is completed by combining the connection box elements when connecting the unit panel, and the conduit is led out to the outside by the connection box. The construction method to perform is also known (for example, refer patent document 2).

  By the way, if it is set as the structure which penetrates the metal conduit inserted in SC wall directly to SC wall panel, it will become a comparatively simple conduit structure. In this case, the SC wall panels are opposed to each other and connected by a tie bar, and a conduit is disposed between the opposing SC wall panels, avoiding the tie bars and studs, and the conduit is inserted into a through hole formed in the SC wall panel. Then, the SC wall panel is fixed in a sandwiched manner by screwing a nut into a screw formed at the tip of the conduit. In this case, conventionally, the hole for inserting the conduit formed in the SC wall panel has been substantially the same diameter as the conduit.

In general, the assembly of the SC wall panel is performed at a processing site. At the time of this assembly, the surface of the SC wall panel is marked according to the arrangement and diameter of the conduit tube, and a predetermined drilling process is performed. The diameter and arrangement of the holes to be formed are set to the diameter and arrangement corresponding to the conduit. When the conduit is an offset conduit such as a Z shape, holes for inserting the conduit are formed in the SC wall panel with an offset dimension corresponding to the offset amount of the offset conduit, and the offset conduit is formed in these holes. Is inserted and fixed by nut tightening or the like.

A wide hole forming step for forming a wide hole having a larger diameter than that, a plate positioning step for positioning a plate that closes the wide hole hole at each wide hole position of each SC wall panel, and the outer diameter of the conduit on the plate A conduit insertion hole forming step for forming a conduit insertion hole of substantially the same diameter, a conduit insertion step for inserting the conduit through the conduit insertion hole, and a plate for fixing the plate to each SC wall panel An SC wall panel conduit mounting method comprising a fixing step and a conduit fixing step of fixing the conduit to the plate. In the mounting method of the conduits in the SC wall panel for mounting the offset conduits penetrating between the opposing SC wall panels, the offset conduits are set at the respective SC wall panels, and the offset conduits are set at the positions. A wide hole forming step for forming a wide hole having a diameter larger than the outer diameter of the plate, a plate positioning step for positioning a plate closing the wide hole at each wide hole position of each SC wall panel, and the offset electric wire on the plate A conduit insertion hole forming step for forming a conduit insertion hole having a diameter approximately equal to the outer diameter of the tube, a conduit insertion step for inserting the offset conduit tube into the conduit insertion hole, and the plate for each SC wall. An SC wall panel comprising: a plate fixing step for fixing to a panel; and a conduit fixing step for fixing the offset conduit to the plate. Mounting method of the inner conduit. The plate for closing the wide hole is for position adjustment having a misalignment absorption margin having an area capable of closing the wide hole even when the conduit insertion hole is shifted to any position within the range of the wide hole. 3. The method for mounting a conduit according to claim 1 or 2, wherein the large plate is used. An offset conduit mounting structure in an SC wall panel for attaching an offset conduit passing therethrough between opposing SC wall panels, each SC wall panel having a wide opening having a diameter larger than the outer diameter of the offset conduit Is formed in an arrangement corresponding to the offset amount of the offset conduit, and each SC wall panel is fixed with a plate that closes each of the wide-mouth holes, and each plate has an outer periphery of the offset conduit. A mounting structure for an offset conduit in an SC wall panel, wherein a conduit insertion hole having a diameter substantially equal to the diameter is formed, and the offset conduit is inserted and fixed in the conduit insertion hole.
