Description

The present invention relates to exterior wall mounting method, in particular, it relates to an outer wall installation method using the wall panels to be installed on the outer periphery of the plant equipment.

  Generally, outer walls such as a soundproof wall, a landscape wall, a tide wall, and a windbreak wall are installed on the outer periphery of a plant facility such as a boiler of a thermal power plant. For example, in Patent Document 1, an outer wall plate A is attached to the ground steel frame (trunk edge) fixed between a pair of ground steel frames (spacers) on the ground to form one block, and the outer wall plate B is attached to the boiler building. A method for installing an outer wall of a boiler building or the like is disclosed in which the blocks are installed with an interval of sheets and the outer wall plate B is fixed to the interval from the inside and assembled.

Further, Patent Document 1 discloses a stud formed of light groove steel (LC steel), a trunk edge fixed between the studs, an overhang trunk edge welded to the outside of the stud, and a trunk edge. A fixed substantially wave-shaped outer wall plate A and a wall panel (block) composed of the outer wall plate A are disclosed.

  However, in the wall panel described in Patent Document 1 described above, the barrel edge fixed between the studs and the overhanging barrel edge welded to the outside of the studs are configured by separate members, and thus fixed to the studs. There are many places and welding places, and the production is troublesome.

  Moreover, since the stud is only composed of a pair of base steel frames, it is weak in strength and it is difficult to increase the size of the wall panel. In particular, when installing a wall panel on the outer periphery of a high-rise building such as plant equipment (for example, 50 to 70 m above the ground), a large amount of wall panel is required if the vertical length (height) of the wall panel is short. The installation work is troublesome.

  Moreover, in the wall panel described in Patent Document 1 described above, since the outer wall plate B is fixed from the inside, how to support the outer wall plate B when the outer wall plate B is fixed becomes a problem. Further, since the hook bolt for fixing the outer wall plate B is inserted from the back side of the folded portion of the outer wall plate B, the fixing operation of the outer wall plate B is troublesome.

The present invention has been made in view of the above-described problems, and an object thereof is to provide an outer wall installation method using a wall panel that is easy to manufacture and install.

According to the present invention, there is provided an outer wall installation method for surrounding an outer periphery of a plant facility, a frame configured by assembling a light groove steel into a rectangle, and an outer wall member disposed so as to cover the frame. A wall panel having a longitudinal length of the frame body set on the basis of the large beam floor of the plant equipment so as to be adjacent to each other on the outer periphery of the plant equipment, and a gap between outer wall members of the wall panel A connecting member or a sealing member having the same structure as that of the outer wall member is fixed from the outside of the wall panel to surround the outer periphery of the plant equipment.

In the invention according to the outside wall installation method described above, the longitudinal length of the frame is set to, for example, 7～15M. In addition, the light groove steel has a main body width H of 400 mm, a folding width A of 75 mm, and a plate thickness t of 6 mm. Further, the light groove steel is preferably press-molded so that the folding angle does not exceed 90 °.

  The outer wall member is preferably a folded plate, an ALC plate, or a GRC plate. For the folded plate, for example, a fluororesin coated steel plate, a polyester coated steel plate, an acrylic coated steel plate or the like is used.

Also, it has a trunk edge composed of a plurality of lip channel steels that are crossed across the surface of the frame body, and the length of the trunk edge is set longer than the lateral width of the frame body and the outer wall member. The outer wall member may be fixed to the trunk edge.

  Furthermore, you may have the suspension piece provided with the supporting member which is detachably arrange | positioned at the both ends of the said frame, and supports the said wall panel so that lamination | stacking is possible.

  According to the above-described wall panel and outer wall installation method according to the present invention, since the longitudinal length of the frame is set with reference to the large beam floor of the plant equipment, the installation work and connection of the wall panel from the inside of the large beam floor Work can be done easily. Moreover, the vertical length of the wall panel can be configured to be about 7 to 15 m, can be made larger than the conventional wall panel, and is installed on the outer periphery of a high-rise building such as a plant facility. However, the required number of sheets can be reduced. Further, since the strength of the wall panel can be maintained by the frame body, it is only necessary to fix the trunk edge to the surface of the frame body, and the wall panel can be easily manufactured.

Further, by adopting LC-400 × 75 × 6 members for the steel material constituting the frame, it is possible to effectively reduce the weight of the frame while maintaining the required strength. In addition, by managing the folding angle of the LC steel (light groove steel) , it is possible to maintain an appropriate strength when the frame is configured.

  In addition, by adopting folded plates, ALC plates, and GRC plates as outer wall members, the outer wall members are excellent in soundproofing, soundproofing, windproofing, aesthetics, etc. according to the type of plant equipment and the performance required for the outer wall. Can be arbitrarily selected and used.

  Moreover, by connecting the suspension piece provided with the support member to the frame, the wall panels can be easily laminated without contacting the outer wall members of the wall panels, and the storage efficiency can be improved. Moreover, a wall panel can be easily lifted by connecting a wire etc. to a suspension piece. Furthermore, by making the suspension piece detachable, the wall panel can be removed when installed on the outer periphery of the plant equipment, and the suspension piece can be reused.

As shown in FIG. 2 (A), the frame 2 has a configuration in which a light groove steel 21 (LC steel) is assembled in a substantially rectangular shape, and a reinforcing member 22 is arranged in the middle by welding or the like to form a substantially ladder. It is formed in a shape. Further, the frame 2 has a vertically long shape as shown in the drawing because the longitudinal length L is set based on the large beam floor of the plant facility. The longitudinal length L and the lateral width W of the frame body 2 are appropriately changed depending on the size of the plant equipment. In general, the longitudinal length L is set to about 7 to 15 m, and the lateral width W is 1 to 1. It is set to about 3m. Further, when assembling the light groove steel 21 (LC type steel material) , it may be joined to each other by welding, bolts or the like using an L-shaped angle material 23 or the like, or the light groove shape steel 21 (LC type steel material). Steel materials) may be welded directly. For example, an L-shaped steel material is used as the reinforcing material 22, but a steel material such as a C-type, LC-type, square-type, or round-type may be used.

The trunk edge 3 is a base member for fixing the outer wall member 4. Here, FIG. 3 is a diagram showing a state in which the trunk edge is connected to the frame, (A) is a front view, and (B) is a longitudinal sectional view. As shown in FIG. 3 (A), the trunk edge 3 is composed of a plurality of lip groove steels 31 (C-type steel materials) that are horizontally and horizontally connected to the surface of the frame body 2.
