Description

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

  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 screwed and fixed to embedded nuts 22 (shown in FIG. 10) 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 includes, for example, a lower heat insulation panel 30 as a fixed piece and an upper heat insulation panel 31 as a folded piece. The lower heat insulation panel 30 covers the lower region 10 a including the lower bolt 20 and the upper bolt 21 on the back surface of the outer wall panel 10, and the upper heat insulation panel 31 covers the upper region 10 b above the upper bolt 21.

  The lower heat insulation panel 30 is fixed to the back surface of the outer wall panel 10 with a tucker or the like. As shown in FIG. 2, the upper heat insulating panel 31 is connected by a connecting piece such as an adhesive tape on the back surface side (opposite side of the outer wall panel 10), and is folded back with respect to the lower heat insulating panel 30 around the linear connecting portion C. It is free. When the upper heat insulating panel 31 is folded, the upper region 10b on the back surface of the outer wall panel 10 is exposed, and when the upper heat insulating panel 31 is expanded and returned to the normal position, the upper region 10b is covered.

  The upper heat insulation panel 31 is located above the center of gravity of the composite panel 1 and includes the left and right ends of the heat insulation panel 11. In addition, since the heat insulation panel 11 is very light compared with the outer wall panel 10, the gravity center of the composite panel 1 is substantially equal to the gravity center of the outer wall panel 10, and is hardly influenced by the position and state of an upper heat insulation panel. With this configuration, when the upper heat insulation panel 31 is folded and the suspension belt is wound around the upper region 10 b of the outer wall panel 10 and lifted, the posture of the composite panel 1 is stabilized and contact between the suspension belt and the heat insulation panel 10 is avoided. .

  The lower heat insulation panel 30 is provided with through holes 32 and 33 through which the lower bolt 20 and the upper bolt 21 pass, respectively. The heat insulating panel 11 is held at a predetermined position 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.

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

  First, for example, a lower bolt 20 and an upper bolt 21 are attached to the outer wall panel 10 placed on the back surface of the outer wall panel 10 in an open space of a construction site or a loading platform of a transport truck. 11 is attached. At this time, the positions of the through holes 32 and 33 of the lower heat insulation panel 30 are aligned with the positions of the lower bolt 20 and the upper bolt 21, respectively, and only the lower heat insulation panel 30 is fixed to the back surface of the outer wall panel 10 with staples or the like. The upper heat insulation panel 31 can be folded back with respect to the lower heat insulation panel 30 with the connecting portion C as an axis. In addition, after completing a part or all of the process so far in a factory etc. beforehand, you may carry in to a construction site.

  Next, for example, as shown in FIG. 3, the upper heat insulating panel 31 is folded back to expose the upper region 10 b on the back surface of the outer wall panel 10.

  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 where the upper heat insulating panel 31 is folded and exposed. . Then, the composite panel 1 is lifted by hooking the ring-shaped end of the suspension belt 40 on the hook of the crane. At this time, since the winding position of the suspension belt 40 is located above the center of gravity of the composite panel 1, the posture of the composite panel 1 is stabilized.

  Next, the composite panel 1 is moved to a predetermined position of the shaft set A as shown in FIG. 5 and placed on the lower mounting portion 50 fixed to the lower flange of the lower beam. The lower mounting portion 50 supports the load of the composite panel 1 and also defines a horizontal piece 50a as a composite panel support portion that defines the height direction position and a vertical position that defines the thickness direction position of the lower end portion of the composite panel 1. And a piece 50b. The composite panel 1 is placed on and supported by the horizontal piece 50a. At this time, the upper part of the composite panel 1 maintains a state separated from the upper beam (the composite panel 1 is in an oblique state).

  Thereafter, the suspension belt 40 is removed as shown in FIG. 6 while the composite panel 1 is supported by other support means such as an operator. Then, the folded upper heat insulating panel 31 is rotated about the connecting portion C and returned to the normal position, and the upper region 10 b of the outer wall panel 10 is covered with the upper heat insulating panel 31.

  Thereafter, as shown in FIG. 7, the composite panel 1 is erected, and the heat insulating panel 1 is brought into contact with the vertical piece 50b of the lower mounting portion 50 of the shaft set A and the upper mounting portion 60 fixed to the lower flange of the upper beam. . The upper mounting portion 60 includes a vertical piece 60a that defines a position in the thickness direction on the upper side of the composite panel 1, for example. The heat insulation panel 11 contacts the vertical piece 60a. 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 the nut 73 is fitted 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 in the work of attaching the composite panel 1 to the shaft set A, the suspension belt 40 is wound around the exposed portion of the outer wall panel 10 formed by folding the upper heat insulating panel 31. be able to. Thereby, it can avoid that the suspension belt 40 contacts the heat insulation panel 11, and the crushing of the heat insulation panel 11 can be prevented.

  Further, the lower bolt 20 and the upper bolt 21 are provided on the back surface of the outer wall panel 10, and the upper heat insulating panel 31 that can be folded back is located above the upper bolt 21, that is, in the region without the fixing portion of the composite panel 1. The upper heat insulation panel 31 can be easily folded and unfolded without interfering with the lower bolt 20 and the upper bolt 21. Further, since the radius of rotation of the upper heat insulation panel 31 when the upper heat insulation panel 31 is rotated about the connecting portion C is reduced, for example, the suspension belt 40 as shown in FIG. It is possible to reduce the inclination angle of the outer wall panel 10 necessary for returning to the position, and to reduce the burden on the means for supporting the outer wall panel 10, thereby improving the safety of work.

  In the above embodiment, the composite panel 1 may be provided with a crush prevention member that prevents the thermal insulation panel 11 attached to the shaft set A from being crushed. In such a case, for example, as shown in FIG. 9, the crush prevention members 80 and 90 are preferably provided at the fixing portion P of the bolt at the center of the composite panel 1 and at both ends B sandwiching the fixing portion P.

  For example, as shown in FIG. 10, the crush prevention member 80 in the upper fixing portion P is formed in a cylindrical shape, for example, and is fitted into the through hole 33. The crush prevention member 80 is slightly longer than the thickness of the heat insulating panel 11, and one end is in contact with the outer wall panel 10 and the other end is in contact with the backing plate 72. Similarly, the crush prevention member 80 in the lower fixing portion P is fitted into the through hole 32, and the other end is in contact with the backing plate 70.

  Moreover, as shown in FIG. 9, both ends B are located in the vicinity of the tips of the vertical pieces 50b and 60a, and a part thereof is hidden by the vertical pieces 50b and 60a. As shown in FIG. 11, a through hole 91 is formed in the heat insulation panel 11 at both ends B. The crush prevention member 90 is formed in a cylindrical shape, for example, and is fitted into the through hole 91. The crush prevention member 90 is longer than the thickness of the heat insulating panel 11, one end is in contact with the outer wall panel 10, and the other end is in contact with the vertical piece 50 b (not shown) or the vertical piece 60 a. Further, a collar portion 90a is provided at an end portion of the crush prevention member 90 on the outer wall panel 10 side.

  The crush preventing members 80 and 90 are made of a hard synthetic resin such as vinyl chloride. The material of the crush preventing members 80 and 90 is not limited to a hard synthetic resin as long as the material has strength and durability and is difficult to become a thermal bridge.

  For example, when an irregular and biased external force is applied to the outer wall panel 10 due to strong wind or the like, the outer wall panel 10 tries to move back and forth with the fixing portion P as a fulcrum. According to the present embodiment, the external force acting on the outer wall panel 10 at this time is applied to the backing plates 70 and 72 and the vertical pieces 50b and 60a via the crush prevention members 80 and 90, and does not act on the heat insulating panel 11. . As a result, no compressive force is applied to the heat insulation panel 11, and the heat insulation panel 11 can be prevented from being crushed.

  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. For example, the upper bolt 21 and the lower bolt 20 use special fixing bolts (torqueless bolts) that have a flange in the middle and reverse the way of cutting the screw before and after the flange. The heat insulating panel 11 and the backing plates 70 and 72 may be sandwiched between the hooks and the nuts 71 and 73 so as to come into contact with the back surface of the steel plate 10. Alternatively, the crush prevention member 80 may be omitted, and a torqueless bolt may be screwed into a position where the flange contacts the back surface of the heat insulation panel 11, and the backing plates 70 and 72 may be sandwiched between the flange and nuts 71 and 73. Further, in the above embodiment, the lower bolt 20 and the upper bolt 21 are provided on the back surface of the outer wall panel 10, and the folded piece of the heat insulation panel 11 is located above the upper bolt 21. The present invention can also be applied to the case of the lower part.

  Further, the positions and number of the folded pieces and the connecting pieces (rotating shafts) are not limited to the above embodiment. For example, as shown in FIG. 12, the heat insulating panel 11 may be divided into three in the vertical direction, the intermediate heat insulating panel 100 may be a folded piece, and the connecting portion C may be provided on the lower side (between the lower heat insulating panel). Further, as shown in FIGS. 13A and 13B, the portion near the upper end may be divided into three in the horizontal direction, and the heat insulating panels 110 at both ends may be folded pieces, and a connecting portion C may be provided on the lower side or side thereof. .

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