Description

  The present invention relates to a method for attaching a composite panel having an outer wall panel and a heat insulating panel, and the composite panel.

  2. Description of the Related Art Conventionally, in a steel structure building using a steel member for a shaft such as a column beam, a heat insulating material is arranged along the rear surface of the outer wall panel.

  At this time, in order to prevent deterioration of the heat insulating property due to the thermal bridge, a heat insulating layer is entirely formed on the outer side of the frame including the part where the outer wall panel is close to the columns and beams constituting the frame. It is preferable to use a sticking heat insulation method.

  Generally, a heat insulating material is made of a fibrous material or a foamable material, and has a low compressive strength. Therefore, a construction method has been proposed in which a heat insulating material is filled in a metal frame such as steel so that a compressive force does not act on the heat insulating material (for example, Patent Documents 1 and 2).

  However, in the method of providing such a frame, there are problems that the frame forms a thermal bridge and that the use of the frame leads to an increase in cost.

  On the other hand, the present applicant has proposed a structure for attaching a heat insulating material to a shaft assembly that realizes an externally bonded heat insulating method without using a frame in Patent Document 3.

  In the construction of the mounting structure for the heat insulating material, the outer wall panel and the heat insulating panel are integrated in advance at a factory or the like to form a composite panel. At the construction site, a suspension belt is wrapped around the composite panel and lifted with a crane, A method of attaching to the shaft assembly is conceivable. Such a method of attaching in units of composite panels is effective in saving labor and uniform quality in field work. However, when this construction method is employed, when the composite panel is lifted, the side edge of the heat insulation panel may be crushed and crushed by the crane belt.

  This invention is made | formed in view of this point, and it aims at preventing the collapse of a heat insulation panel in the method of attaching a composite panel to a shaft assembly.

  In order to achieve the above object, the present invention is a method of attaching a composite panel having an outer wall panel and a heat insulating panel covering the back surface of the outer wall panel to a shaft set of a building, and is attached to the shaft set on the back surface of the outer wall panel. A suspension belt is attached to a portion of the outer wall panel where the lower heat insulation panel is not attached in a state where the lower heat insulation panel formed by dividing the heat insulation panel is attached to a lower region including a lower fixing portion for fixing. The outer wall panel is lifted and moved by the suspension belt, placed on the lower mounting portion of the shaft assembly, the suspension belt is removed, and the shaft assembly on the back surface of the outer wall panel is fixed to the shaft assembly. The heat insulation panel is divided and formed in an upper region including an upper fixing part for the lower heat insulation panel is not attached. And a step of attaching the upper insulating panel, and fixing the lower fixing portion and the upper fixed part of the outer wall panel to the lower attachment portion and the upper attachment portion of the framing, the.

  According to the present invention, when the outer wall panel is lifted, the suspension belt is not wound around the heat insulation panel, so that the heat insulation panel can be prevented from being crushed. Moreover, since the lower heat insulation panel is attached to the outer wall panel before lifting the outer wall panel, the work of attaching the composite panel to the shaft assembly is simplified.

  When the upper heat insulating panel is attached to the outer wall panel, the upper heat insulating panel may be positioned by inserting a through hole formed in the upper heat insulating panel into a bolt of the upper fixing portion of the outer wall panel. . In this case, the positioning operation of the heat insulation panel on the back surface of the outer wall panel becomes easy.

  The heat insulation panel is divided into the lower heat insulation panel, the upper heat insulation panel, and an intermediate heat insulation panel, and the intermediate heat insulation panel is attached to the outer wall panel after fixing the outer wall panel to the shaft assembly. You may do it. In such a case, the dimensions of the upper heat insulation panel and the lower heat insulation panel that are attached to the shaft assembly can be reduced, so that, for example, attachment work in an unstable place at a high place can be performed quickly.

  The present invention according to another aspect is a composite panel that is attached to a building frame and includes an outer wall panel and a heat insulating panel that covers the back surface of the outer wall panel, and the heat insulating panel is at least on the back surface of the outer wall panel. Divided into a lower heat insulating panel covering a lower region including a lower fixing portion for fixing to the shaft set and an upper heat insulating panel covering an upper region including an upper fixing portion for fixing to the shaft set on the back surface of the outer wall panel. At least the upper heat insulating panel is detachable from the outer wall panel.

  According to the present invention, when the outer wall panel is lifted in the work of attaching the composite panel to the shaft assembly, the suspension belt can be wound around a portion where the back surface of the outer wall panel formed by removing the upper heat insulating panel is exposed. Therefore, the suspension belt does not have to be wound around the heat insulation panel when the outer wall panel is lifted, so that the heat insulation panel can be prevented from being crushed.

  The present invention according to another aspect is a composite panel that is attached to a building frame and includes an outer wall panel and a heat insulating panel that covers the back surface of the outer wall panel, the heat insulating panel at least on the back surface of the outer wall panel.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory diagram showing an outline of the configuration of the composite panel 1 according to the present embodiment. FIG. 1A is a front view of the composite panel 1, and FIG. 1B is a side view of the composite panel 1.

  The building in the present embodiment is a steel frame industrialized house having a flat module M of, for example, 305 mm. The composite panel 1 is attached so as to be connected to a plurality of frames composed of column beams of the building, and constitutes the wall surface of the building. The composite panel 1 includes an outer wall panel 10 and a heat insulating panel 11 that covers the entire back surface of the outer wall panel 10.

  The outer wall panel 10 is made of lightweight cellular concrete, for example. For example, the length of the outer wall panel 10 is substantially equal to the floor height (the dimension from the top of the lower beam to the top of the upper beam), and there are basically two types of width dimensions of M × 1 (305 mm) and M × 2 (610 mm).

  On the back surface of the outer wall panel 10, a lower bolt 20 as a lower fixing part for fixing to a building frame and an upper bolt 21 as an upper fixing part are attached. The lower bolt 20 and the upper bolt 21 are erected in a direction perpendicular to the back surface of the outer wall panel 10. The lower bolt 20 and the upper bolt 21 are fixed by being screwed into embedded nuts (not shown) embedded in the outer wall panel 10.

  The heat insulation panel 11 is obtained by pasting a polyester nonwoven fabric on both sides of, for example, a phenol resin foam (phenol foam). The overall width dimension and height dimension of the heat insulation panel 11 correspond to the width dimension and the height dimension of the outer wall panel 10 almost equally.

  The heat insulation panel 11 is divided into, for example, a lower heat insulation panel 30 and an upper heat insulation panel 31. The lower heat insulation panel 30 covers the lower region 10 a including the lower bolt 20 on the back surface of the outer wall panel 10, and the upper heat insulation panel 31 covers the upper region 10 b including the upper bolt 21 on the back surface of the outer wall panel 10.

  As shown in FIG. 2, the lower heat insulation panel 30 and the upper heat insulation panel 31 are provided with through holes 32 and 33 through which the lower bolt 20 and the upper bolt 21 pass, respectively. The lower heat insulation panel 30 and the upper heat insulation panel 31 are held at predetermined positions on the back surface of the outer wall panel 10 by fitting the through holes 32 and 33 into the lower bolt 20 and the upper bolt 21. In addition, a cylindrical spacer that is longer than the thickness of the heat insulating panel 11 and contacts the back surface of the outer wall panel 10 is provided between the through hole 32 and the lower bolt 20 or between the through hole 33 and the upper bolt 21. The pressure transmitted to the heat insulation panel 11 may be reduced. In addition, the lower bolt 20 and the upper bolt 21 may use special fixing bolts (torqueless bolts) that have a flange in the middle portion and are reversely threaded before and after the flange. The scissors may be screwed into contact with the back surface of the outer wall panel 10, and the heat insulating panels 30 and 31 and the backing plate 70 may be sandwiched between the scissors and a nut 71 described later.

  The composite panel 1 composed of the outer wall panel 10 and the heat insulation panel 11 configured as described above is attached to the building frame in the vertical and horizontal directions.

  Next, a method for attaching the composite panel 1 to the shaft assembly will be described.

  First, for example, as shown in FIG. 3, lower bolts 20 and upper bolts 21 are placed on the lower region 10a of the outer wall panel 10 placed with the back side up on, for example, an open space of a construction site or a loading platform of a transport truck. Further, the lower heat insulation panel 31 is attached to the back surface of the outer wall panel 10. In a factory or the like, all or a part of the lower bolt 20, the upper bolt 21, and the lower heat insulation panel 30 may be attached to the outer wall panel 10 in advance, or the upper wall insulation panel 31 and the upper heat insulation panel 31 may be attached. The upper heat insulating panel 31 may be removed at the site.

  Subsequently, as shown in FIG. 4, a crane suspension belt (sling belt made of synthetic fiber such as nylon) 40 is wound around the upper region 10b of the outer wall panel 10 to which the upper heat insulating panel 31 is not attached. Thereafter, the outer wall panel 10 is lifted by hooking the ring-shaped end portion of the suspension belt 40 on the hook of the crane. Then, the outer wall panel 10 is moved to a predetermined position as shown in FIG. 5, and the lower mounting portion 50 (supporting the load of the outer wall panel 1 and defining the height direction position is fixed to the upper flange of the lower beam. It is placed and supported on a horizontal piece (outer wall panel support) 50a of a horizontal piece 50a and a vertical piece 50b that defines the thickness direction position of the lower end of the outer wall panel 10. At this time, the upper part of the outer wall panel 10 maintains a state separated from the upper beam (an oblique state).

  Thereafter, the suspension belt 40 is removed as shown in FIG. 6 while the outer wall panel 10 is supported by other support means such as an operator. Then, the upper heat insulating panel 31 is attached to the upper region 10 b of the outer wall panel 10. At this time, the through hole 33 of the upper heat insulation panel 31 is fitted into the upper bolt 21 to position the upper heat insulation panel 31.

  Thereafter, as shown in FIG. 7, the outer wall panel 10 to which the heat insulation panel 11 (the lower heat insulation panel 30 and the upper heat insulation panel 31) is attached is erected, and the vertical piece 50 b of the lower attachment portion 50 of the shaft assembly A is below the upper beam. The heat insulating panel 11 is brought into contact with the vertical piece 60a of the upper mounting portion 60 (having the vertical piece 60a that defines the thickness direction position on the upper side of the composite panel 1) fixed to the flange. Next, with the vertical piece 50b sandwiched, the backing plate 70 is inserted into the lower bolt 20, and the nut 71 is screwed into the lower bolt 20 from the outside and tightened. Further, the backing plate 72 is inserted into the upper bolt 21 with the vertical piece 60a being sandwiched, and a nut 73 is screwed into the upper bolt 21 from the outside and tightened. In this way, the composite panel 1 is fixed to the shaft set A.

  As shown in FIG. 8, a plurality of composite panels 1 are sequentially attached to the shaft set A to form a wall surface of the building.

  According to the above embodiment, when the outer wall panel 10 is lifted and transported to the shaft assembly A, the suspension belt 40 is wound around the upper region 10b without the upper heat insulation panel 31 on the back surface of the outer wall panel 10, so that the heat insulation is performed. The panel 11 is prevented from being crushed. In addition, since the lower heat insulation panel 30 is attached to the outer wall panel 10 before being transported to the shaft assembly A, the mounting work in an unstable state at a high place is reduced, and the composite panel 1 is attached to the shaft assembly A. Installation work can be performed safely and promptly.

  Further, when the upper heat insulating panel 31 is attached to the outer wall panel 10, the upper heat insulating panel 31 is positioned by inserting the through hole 33 of the upper heat insulating panel 31 into the upper bolt 21 of the outer wall panel 10. For this reason, positioning of the upper heat insulation panel 31 in the back surface of the outer wall panel 10 can be performed easily.

  In the above embodiment, although the heat insulation panel 11 was divided | segmented into two, you may divide | segment into three. In such a case, for example, as shown in FIG. 9, the heat insulation panel 11 is divided into a lower heat insulation panel 30, an upper heat insulation panel 31, and an intermediate heat insulation panel 80. The intermediate heat insulation panel 80 can be freely attached to the intermediate region 10c where the bolts 20 and 21 on the back surface of the outer wall panel 10 are not provided. In addition, the height dimension of the lower heat insulation panel 30 and the upper heat insulation panel 31 is small by the amount of the intermediate heat insulation panel 80.

  In the attaching operation of the composite panel 1 in such a case, first, as shown in FIG. 10, the lower heat insulating panel 30 is attached to the outer wall panel 10 to which the lower bolt 20 and the upper bolt 21 are attached as in the above embodiment.

  Next, as shown in FIG. 11, the suspension belt 40 for a crane is wound around the upper region 10b or the intermediate region 10c where the upper heat insulation panel 31 and the intermediate heat insulation panel 80 of the outer wall panel 10 are not attached. Thereafter, as in the above embodiment, the end portion of the suspension belt 40 is hooked on the hook of the crane, the outer wall panel 10 is lifted, moved to a predetermined position, and placed and supported on the horizontal piece 50a of the lower attachment portion 50.

  Thereafter, the suspension belt 40 is removed as shown in FIG. 12 in a state where the outer wall panel 10 is supported by other support means such as an operator as in the above embodiment, and the upper heat insulating panel is placed in the upper region 10b of the outer wall panel 10. 31 is attached.

  Next, as shown in FIG. 13, the outer wall panel 10 to which the lower heat insulating panel 30 and the upper heat insulating panel 31 are attached is erected, and the outer wall panel 10 and the upper heat insulating panel 30 and the upper heat insulating panel 30 and the upper heat insulating panel 31 are It fixes through the heat insulation panel 31. Then, the composite panel 1 is attached to the shaft set A by fitting the intermediate heat insulation panel 80 into the intermediate region 10c of the outer wall panel 10 as shown in FIG.

  As shown in FIG. 15, a plurality of composite panels 1 are sequentially attached to the shaft set A to form a wall surface of the building.

  According to the present embodiment, by dividing the heat insulation panel 11 into three, the height dimension of the lower heat insulation panel 30 and the upper heat insulation panel 31 can be reduced, and the shaft A in an unstable place can be obtained. The lower heat insulation panel 30 and the upper heat insulation panel 31 can be attached safely and promptly.

  Further, the intermediate heat insulation panel 80 can be easily attached and detached because there is no fixed portion such as the bolts 20 and 21, so that the heat insulation panel 11 can be easily replaced, for example. In addition, when the composite panels 1 are arranged as shown in FIG. 16, the intermediate heat insulation panel 80 can be passed over the adjacent composite panels 1, for example, by using the intermediate heat insulation panel 80 having a large size. It becomes possible to improve.

  In the present embodiment, the intermediate heat insulation panel 80 may be further divided into a plurality of pieces, and the whole heat insulation panel 11 may be divided into four or more.

  The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to such examples. It is obvious for those skilled in the art that various modifications or modifications can be conceived within the scope of the idea described in the claims, and these naturally belong to the technical scope of the present invention. It is understood.

  For example, in the above embodiment, other means may be used as the fixing means between the outer wall panel 10 and the attachment portions 50 and 60 of the shaft set A. Moreover, in the above embodiment, although the lower heat insulation panel 30 and the upper heat insulation panel 31 were detachable with respect to the outer wall panel 10, at least the upper heat insulation panel 31 should just be detachable.

  The present invention is useful in preventing the thermal insulation panel from being crushed when the composite panel is attached to the shaft assembly.
