Description

  The present invention relates to a mounting structure for mounting a concrete panel such as an ALC (lightweight cellular concrete) panel to a structural frame such as a building frame.

  2. Description of the Related Art Conventionally, concrete panels such as ALC panels have been widely used as roof materials, floor materials, outer wall materials, partition wall materials, etc. for buildings such as steel structures. In addition, this type of concrete-based panel is generally formed in a rectangular plate shape, and when it is attached to a structural enclosure such as a building enclosure, a construction method in which both ends in the panel longitudinal direction are attached to the structural enclosure is the mainstream. Furthermore, in order to follow the deformation and displacement of the structural frame due to an earthquake or the like, a locking construction method or a sliding construction method in which a locking function or a sliding function is given to the panel mounting portion is adopted.

  For example, when an ALC panel is used as an outer wall material or partition wall material, a book composed of a projection (male) and a recess (female) that fit together in the joint, particularly the long edge of the panel, in consideration of fire resistance Although the specification which provided the actual joint is common and it is not necessarily common, when using as a roofing material or a flooring, the panel which gave this actual joint may be employ | adopted.

  The actual joint in the ALC panel is designed to have a certain gap between the convex part and the concave part that should be engaged with each other so that processing errors due to the material of the panel and manufacturing reasons can be absorbed. Has been. In addition, since the ALC base material contains bubbles, it is relatively fragile, and if the corners are processed at right angles or acute angles, there is a risk of chipping during transportation or construction. The cross-sectional shape of the recess is formed in a trapezoid slightly larger than that.

  However, if a wall, roof, or floor surface is formed using a panel having the actual joint as described above and leans against the wall surface or jumps on the roof or floor surface, the convex portion of the real joint is formed. The gap between the recesses and the recesses may cause rattling or visually or sensory unstable panel misalignment. In particular, when the panel is used long, it is easy to bend and the joint is not sufficiently restrained in the out-of-plane direction. The panel may vibrate in the out-of-plane direction due to the vibration of the casing or the like, and there may be a rattling sound due to the collision of the actual joint.

  In response to the above-mentioned concerns, Patent Document 1 below proposes joining and fixing adjacent panels by filling the actual joint of the ALC panel with an adhesive and solidifying it. In particular, the document 1 proposes that an adhesive is interposed over the entire length in the longitudinal direction of the actual joint provided along the long side edge of the floor or roof panel.

JP 2004-115707 A

  However, in the case where the actual joint is filled with an adhesive as described above and the joint is solidified, the joint does not slide, so when the structural frame is deformed or displaced by vibration due to an earthquake or the like, for example, There is a risk that the load may be concentrated, or an excessive force may be applied to cause damage or breakage. In addition, because the joints do not slide, when the rocking construction method is adopted, for example, when the structural frame is deformed or displaced by vibration due to an earthquake etc., it is not possible to lock the panel by following it and prevent damage to the panel etc. There is a bug.

  The present invention has been proposed in view of the above-mentioned problems. When a wall or the like is formed using a concrete panel such as an AlC panel as described above, sliding at a joint portion of an adjacent panel is prevented. Therefore, it is possible to follow the movement of the structural body due to an earthquake or the like satisfactorily. For example, even when the locking construction method is employed, the locking operation of the panel is not impaired, and the eyes in the out-of-plane direction of the panel It is an object of the present invention to provide a concrete panel mounting structure that can satisfactorily prevent differences and rattling.

  In order to achieve the above object, the concrete panel mounting structure according to the present invention has the following configuration. That is, in a state where the substantially rectangular concrete panels are arranged in at least the width direction, the convex portion and the concave portion of the actual joint formed at the long side edge of the panel adjacent in the width direction are engaged, and the above A concrete panel mounting structure in which the end in the length direction of each panel is attached to the structural frame, and a gap is provided between the convex portion and the concave portion of the panel adjacent in the width direction. The present invention is characterized in that a cushioning material is interposed at a substantially central portion in the longitudinal direction of the panel.

  According to the concrete panel mounting structure according to the present invention configured as described above, the concentrated load acting on the panel is effectively transmitted to the adjacent panel by the actual joint, so that there is no occurrence of a mistake or rattling. Further, since the joint is slidable, for example, a rocking construction method or the like can be adopted as a panel construction method. Furthermore, the construction structure of the concrete panel according to the present invention does not require the use of mortar or adhesive, so the construction is simple, does not pollute the site, and is easier and less expensive than using adhesives. There are effects such as being able to.

  Each concrete panel has its lengthwise end attached to the structural frame so that it can be locked, and the cushion material can slide relative to at least one of the adjacent panels without disturbing the locking operation. It is good to configure. For example, when an outer wall or partition wall is configured with an ALC panel, the rocking construction method generally has a higher deformation tracking performance than the slide construction method. Especially when a long panel is used, the slide construction method uses joint width and hardware for adjusting the expansion and contraction. Although it is necessary to design the size of the bolt hole to be loose, it is not always a realistic dimension to design the size so as to be sufficiently slidable, and there is a high demand for adopting the locking construction method.

  Moreover, although the material of the said cushion material is appropriate, for example, a ceramic fiber blanket or a rock wool blanket can be used. When such cushion materials are used, since they are non-combustible materials, there is an advantage that no harmful gas is generated even in the event of a fire and that environmental hygiene is preferable. Further, when using the cushion material as described above, the thickness is preferably about 6 to 13 mm, and the length, that is, the filling length between the convex portion and the concave portion is preferably 200 to 500 mm.

(A) is a BB enlarged transverse plan view in FIG. 1, (b) is an enlarged view of a part thereof. (A) And (b) is explanatory drawing which shows the structure of the joint part of the said embodiment.

  Hereinafter, a concrete panel mounting structure according to the present invention will be specifically described based on an embodiment shown in the drawings.

  The embodiment shown in FIGS. 1 and 2 is an application of the present invention to a wall panel mounting structure in the case where an ALC panel is used as a concrete panel to form a partition wall. Between the ceiling-side structural housing F1 such as a ceiling slab and the floor-side structural housing F2 such as a floor slab, the surface (front) rectangular ALC panel 1 is vertically long and lateral (width direction, A partition wall is formed by arranging a large number in the left-right direction in FIG.

  As shown in FIGS. 1 and 2, each panel 1 has upper and lower ends on the lower surface of the structural housing F1 on the ceiling side and the upper surface of the structural housing F2 on the floor side. Are respectively attached by means of mounting bolts 3 and an Inazuma plate 4 or the like. The base angles 2 are fixed to the anchor hardware 5a and 5b embedded in the structural bodies F1 and F2 by welding or the like, and the panels 1 are placed on the base angle 2 below the flat plate 6 via the flat plate 6. Is placed. In the figure, 7 is a fireproof joint material interposed between the upper end surface of each panel 1 and the base angle 2 on the ceiling side.

  Anchor insertion holes h are formed at both upper and lower ends of each panel 1, and each mounting bolt 3 is screwed into a female screw hole 8a of an anchor 8 inserted into each anchor insertion hole h. 3 is clamped and fixed between each head 1 and each panel 1, and an upright piece or a hanging piece (up and down) of the base angle 2 is placed between the respective inazuma plate 4 and each panel 1. It is a configuration with a piece of direction) in between.

  In addition, each said Inazuma plate 4 is fixed to the foundation | angular angle 2 by means, such as welding, and each said mounting bolt 3 is being fixed by the predetermined | prescribed tightening torque which can be rotated with respect to the anchor 8. FIG. With the above configuration, each panel 1 can be rocked in the panel surface direction (direction parallel to the surface in FIG. 1), whereby the structural housing is deformed or displaced by vibration due to an earthquake or the like. Even in such a case, it is possible to prevent the panel 1 from being damaged by an excessive force acting on each panel.

  As shown in FIG. 3 (a), the actual joint 10 comprising a convex portion 11 and a concave portion 12 engaged with the long side edge surface on both sides in the width direction (left and right direction in FIG. 1) of each panel 1 is provided. Is provided, and a cushion material 15 is filled in a gap S formed between the convex portion 11 and the concave portion 12. Although the shape of the convex part 11 and the concave part 12 is appropriate, in the present embodiment, an ALC panel is used as the panel 1, and the base material is relatively fragile with bubbles as described above. As shown in (b), the angle θ1 of the corner on the tip side of the convex portion 11 is formed in a trapezoidal cross section, and the cross sectional shape of the concave portion 12 is also formed in a slightly larger trapezoid accordingly. ing.

  Further, the distances t1 and t2 between the convex portion 11 and the concave portion 12 shown in FIG. 4A are appropriate, but when the ALC panel as in this embodiment is used, What is necessary is just to form substantially the same as the space | interval dimension between the convex part 11 and the recessed part 12 formed in an ALC panel. Specifically, for example, the distance t1 between the top surface 11a of the convex portion 11 and the bottom surface 12a of the concave portion 12 shown in FIG. 4 (a), and between the side surface 11b of the convex portion 11 and the side surface 12b of the concave portion 12 are illustrated. What is necessary is just to design the space | interval dimension t2 to about 2-3 mm respectively. This is because the actual joint 10 of the ALC panel as described above is formed by cutting the autoclave-cured panel with a rotary blade. Depending on the degree of wear, etc., the depth of the concave portion 12 may often be shallower than the height of the convex portion 11, and in such a case, when the convex portion 11 and the concave portion 12 are fitted together, In addition, there is a risk that the long side edge surfaces of adjacent panels cannot be brought into contact with each other in a state where they are in close contact with each other, so that the fire resistance is deteriorated or the appearance is impaired.

  Although the height dimension of the said convex part 11 and the recessed part 12 is also appropriate, in the ALC panel like this embodiment, the height dimension d1 of the convex part 11 in FIG.4 (b) is about 7-10 mm. It is desirable to do. The reason for this is that the convex portion 11 of the ALC panel is generally formed by cutting the other long side edge, and in order to increase the height of the convex portion 11, a large width that allows for the cutting margin of the panel in advance. It is necessary to manufacture a panel having dimensions, and if the height of the convex portion 11 is too high, the amount of cutting of the panel increases, which is uneconomical. If the height of the convex portion 11 is too low, for example, This is because when a fire or the like occurs after laying the panel, there is a risk that fire, smoke, hot air, etc. may circulate from the joint.

  Further, the depth d2 of the concave portion 12 may be about 9 to 13 mm by adding the gap size t1 to the height dimension d1 of the convex portion 11. Further, the width dimension B1 of the convex part 11 and the width dimension B2 of the protruding part 13 on both sides of the concave part 12 are the above-mentioned so as not to be damaged when the convex part 11 or the concave part 12 is processed or when the panel is transported or constructed. It is desirable that the depth d2 and the height dimension d1 be about twice or more.

  Although the material of the cushion material 15 is appropriate, for example, a heat-resistant or flame-retardant fiber formed in a mat shape, specifically, a ceramic fiber blanket, a rock wool blanket, or the like can be used. The cross-sectional shape of the cushion material 15 is appropriate. For example, as shown in FIGS. 5 (a) and 5 (c), it is possible to use a material obtained by cutting a long strip into a predetermined length L.

  In addition, concrete panels such as ALC panels as described above generally have a length of about 3000 mm for wall materials and about 2000 mm for horizontal materials such as roofs and floor materials. In some cases, the length L of the cushion material 15, that is, the cushion material 15 into the gap S between the convex portion 11 and the concave portion 12 may be used. The filling length is preferably about 200 to 500 mm. The reason is that in order to make it difficult to cause local destruction of the installation position of the cushion material 15, it is preferable that the length is 200 mm or more, and considering the effect of the cushion material and ease of installation work, it is 500 mm or less. This is because it is appropriate to do.

  Further, the width W of the cushion material 15 is equal to or more than the dimension obtained by adding the width dimension a of the bottom surface 12a of the recess 12 and the width dimensions b · b of both side surfaces 12b and 12b as shown in FIG. It is only necessary to form the cushion material 15 to be slightly smaller, and when the gap S between the convex portion 11 and the concave portion 12 is filled at least as shown in FIGS. What is necessary is just not to protrude from the clearance gap S.

  Further, the free thickness t of the cushion material 15 in FIG. 5 (a) is such that when the gap S is filled, the side surfaces 11b and 11b of the convex portion 11 and the side surfaces 12b and 12b of the concave portion 12 are The adjacent panel may be compressed and fixed to the extent that it does not easily shift in the thickness direction by the cushioning material interposed between them, and the panel 1 is attached so that it can be locked as in the above embodiment. In such a case, it is necessary to allow the locking operation satisfactorily and to fully exhibit the locking function without hindering the locking operation. For this purpose, for example, when a ceramic fiber blanket or a rock wool blanket is used as the cushion material 15 and the gap S of the actual joint 10 is set to 2 to 3 mm as described above, the cushion against the cushion material 15 is used. The thickness t of the material 15 is suitably about 6 to 13 mm. If it is thinner than that, it will not be possible to fill the gap S of the actual joint 10 with a necessary and sufficient density, and if it is thicker than that, it will be difficult to compress it manually or prevent smooth locking operation. This is because there is a risk of such.

  The cushion material 15 may be interposed at least between the side surfaces 11b and 11b of the convex portion 11 and the side surfaces 12b and 12b of the concave portion 12, and the top surface 11a of the convex portion 11 and the concave portion 12 Although not necessarily interposed between the bottom surface 12a, the entire gap S between the convex portion 11 and the concave portion 12 including the space between the top surface 11a and the bottom surface 12a is shown in FIGS. When the belt-like cushion material 15 as shown is interposed, there is an advantage that it can be easily mounted in the gap S.

  Further, the mounting method and fixing means of the cushion material 15 in the gap S are appropriate. For example, as shown in FIG. 5, it is efficient to attach the cushion material 15 at a position where it can be visually confirmed before standing up. And it can attach to an appropriate position accurately. In that case, the cushion material 15 may be mounted on either side of the convex portion 11 and the concave portion 12, but as shown in FIG. . As a fixing method, when the cushion material 15 is pushed into the recess 12 in a slightly compressed state, the cushion material 15 can be held in the recess 12 by its elastic restoring force. If it is temporarily fixed with a fixing tool 16 such as a tucker as shown in the figure or an adhesive (not shown) of a spray paste, it does not have to fall off during construction.

  In the above embodiment, the mounting structure of the concrete panel according to the present invention is applied to the mounting structure of the ALC panel constituting the partition wall. However, the roof or floor is not limited to the partition wall but as a wall panel such as an outer wall or limited to the wall panel. The present invention can also be applied to the case where the concrete panel is attached to a structural frame such as a building frame as a horizontal panel such as a material. Further, the concrete panel is not limited to the ALC panel, but can be applied to various types of concrete panels attached to the structural frame, and the same effect as described above can be obtained.

  As described above, according to the concrete-based panel mounting structure of the present invention, the concentrated load acting on the panel is effectively transmitted to the adjacent panel by the actual joint, so there is no occurrence of misunderstanding or rattling, and the joint Since it is slidable, for example, a locking construction method or the like can be adopted as a panel construction method. Furthermore, the concrete panel mounting structure according to the present invention does not require the use of a mortar, an adhesive, or the like for mounting the panel to the structural frame. Moreover, it is cheaper than adhesives. In addition, when ceramic fiber blanket or rock wool blanket is used as the cushioning material, because they are non-combustible materials, there are no harmful gas generation even in the event of a fire, and advantages such as favorable environmental hygiene And can be used effectively industrially.
