Description

  The present invention relates to a face material mounting structure.

  Generally, in the construction of medium- and high-rise buildings, an exterior curtain wall construction method in which a face material is attached to the outer surface of a structural frame is widely performed.

  One of the exterior curtain wall methods is a knockdown method. The knockdown method is a method of assembling a vertical structure, which is a long vertical member, and an invisible grid structure, which is a horizontal member, on the outer periphery of the structure body while installing the structure on the structure body at the construction site. Patent Document 1 discloses a knock-down curtain wall mounting structure as shown in FIG.

  12A is a perspective view of a main part of the curtain wall 100 mounting structure, and FIG. 12B is a cross-sectional view of the vertical joint. The curtain wall 100 fixes the vertical stand 101 along the vertical direction at a predetermined interval in the horizontal direction, and then spans the blinds 102 between the vertical portions 101 at a predetermined interval in the vertical direction. The vertical frame 103 is attached to the outdoor side surface to form an opening frame, and the side frame 104 is attached to the outdoor side surface of the vertical frame 103, and then the glass 105 is fitted into the fitting groove of the joint 102, and the glass side edge is attached to the side frame 104. It has the structure fixed by the pressing edge 106 attached to the.

  In such a vertical and invisible curtain wall mounting structure, the area formed by the upright and invisible is usually rectangular, but when an earthquake occurs, the interlayer displacement due to the distortion of the structural frame Due to the influence, the stance tilts diagonally, while the invisible eye keeps approximately horizontal, so it transforms into a parallelogram. That is, since the face material attached to such a curtain wall structure is also affected by the interlayer displacement, various face material attachment structures for reducing damage to the face material and preventing falling off are being studied.

  For example, if the face material is glass, install the glass in a curtain wall structure with vertical and invisible lines so that the glass does not interfere with the vertical and invisible lines when tilted due to the effect of interlayer displacement. , Method to examine by boucam type, Dot point glazing (DPG) method in which countersunk holes are made in four corners of glass, and bolts with a rotating mechanism are attached and fixed, sandwiching the edge part of glass from inside and outside A fixed metal point glazing (MPG) method has been proposed.

  Even when the face material is lightweight aerated concrete (ALC) cured with autoclave, extruded cement board, or stone, the face material mounting structure utilizing the unique properties of the face material has been established and standardized. .

  By the way, when the face material is an aluminum panel, the face material attachment structure is not standardized. Therefore, various face material attachment structures are used according to the building to be constructed. As a structure that is used relatively frequently, there is a structure in which an aluminum panel is directly fastened to a L-angle base or the like with a drill screw.

  Another structure for attaching an aluminum panel is the structure shown in FIG. FIG. 13A shows a face material mounting structure 110 that employs the sway method, which is known as a face material interlayer displacement tracking mechanism. The face material mounting structure 110 includes three vertices 111 and three invisible 112, and an aluminum panel 113 is installed between the vertices 111. The aluminum panel 113 is joined to the vertical 111 at the connection portion 114 and the connection portion 115.

  FIG. 13B shows a cross-sectional view of the connection portion AA ′. The aluminum panel 113 includes a plate body 113a and a vertical member 113b joined to the back side of the plate body 113a. The vertical member 113b is vertically joined to the back side of the plate body 113a along both sides in the vertical direction of the plate body 113a. When the two plate bodies 113a are provided side by side, the vertical members 113b on the adjacent side sides are positioned adjacent to each other. A supporting steel material 118 having a U-shaped cross section, which is composed of one web 118a and two flanges 118b, is installed so as to sandwich the two adjacent vertical members 113b. A gap is provided between the side surface of the vertical member 113 b and the inner side surface 118 d of the flange 118 b of the support steel material 118. The aluminum panel 113 and the support steel material 118 are joined by joining steel materials 116 and 117 such as L-angle. The support steel material 118 is joined to the vertical 111 by a steel material (not shown).

  FIG. 13C shows a cross-sectional view of the connection portion BB ′. In the connecting portion 115, a hole or notch 113c is formed in the vertical member 113b. A hole 118c is also opened at a position corresponding to the longitudinal member 113b of the flange 118b of the support steel material 118. A steel bar 119 is provided through these holes or notches 113 c and holes 118 c, and both ends of the steel bar 119 are joined to the flange 118 b of the support steel material 118. The supporting steel material 118 is joined to the vertical 111 by the joining steel material 120.

  As described above, in the connection portion 114, the aluminum panel 113 is fixed to the stand 111 so as not to move, and is configured to support the weight of the aluminum panel 113. On the other hand, in the connection portion 115, the aluminum panel 113 and the support steel material 118 are connected via the steel rod 119 by the distance of the gap between the side surface of the vertical member 113b and the inner side surface 118d of the flange 118b of the support steel material 118. It is possible to move relative to the left and right. By having such a configuration, even if the seismic force acts in the direction of the arrow in FIG. 13A and the vertical 111 is tilted, the aluminum panel 113 follows the movement of the vertical 111 at the connecting portion 114. The connecting portion 115 does not follow the movement of the vertical 111 and moves in the lateral direction relative to the vertical 111. This prevents the aluminum panel 113 from being affected by the interlayer displacement.

  Further, since the two adjacent aluminum panels 113 are joined together by one support steel material 118 on their adjacent sides, the number of the support steel materials 118 is reduced, and the steel material cost is reduced. It is possible.

JP 2001-311251 A

  As described above, when the face material is an aluminum panel, the face material attachment structure considering the influence of the interlayer displacement is not standardized. That is, for each building to be constructed, it is necessary to determine an appropriate surface material mounting structure according to the shape, structure, delivery date, etc. of the building. Cost increases.

  In the structure in which the aluminum panel is directly fastened to the ground with a drill screw, the aluminum panel is directly fixed to the ground steel material fixed to the structural frame. It becomes. Therefore, the face material is easily affected by the interlayer displacement, and the face material may be damaged during an earthquake. Or a joined part may be damaged and a face material may fall off.

  Further, in the method shown in FIG. 13, it is necessary to provide the connection portions 114 and 115 on adjacent sides of the two aluminum panels 113. That is, since the connecting portions 114 and 115 cannot be provided at any place on the aluminum panel 113, the shape and layout of the finished surface material are limited.

  In the method shown in FIG. 13, in order to increase the shape of the finished surface material and the degree of freedom of allocation, it is conceivable that the installation positions of the connecting portions 114 and 115 do not depend on the shape of the finished surface material. For example, by providing the connection portions 114 and 115 at arbitrary positions such as near the center of the aluminum panel 113, the shape of the finished surface material can be prevented from being limited to the position of the support steel material 118. However, as shown in FIGS. 13B and 13C, the two aluminum panels 113 cannot be supported simultaneously by one support steel material 118, and the support steel material 118 is provided for each of the connection portions 114 and 115. Since it must be installed, the usage amount of the support steel material 118 and the vertical body 111 is increased, thereby increasing the steel material cost.

  Further, in the method shown in FIG. 13, when an aluminum panel 113 having a shape that is curved in a direction perpendicular to the surface is to be installed, the supporting steel material 118 is made to correspond to the shape of the aluminum panel 113, and the web It is necessary to curve in a direction perpendicular to 118a. However, it is not easy to bend a steel material having a U-shaped cross section in a direction perpendicular to the web 118a. For this reason as well, the shape of the finished surface material is limited.

  The problem to be solved by the present invention is to provide a face material mounting structure in which the shape of the finished surface material and the degree of freedom of assignment are high, and the construction cost can be reduced.

The present invention employs the following means in order to solve the above problems. That is, the present invention provides a surface material that is installed in a structural housing and has a groove portion extending in a length direction on at least one side surface, and a surface material attached to the surface through a plurality of fasteners. The plurality of fasteners has a face material mounting structure that is attached to the invisible by a latching portion that engages with the groove and is movable relative to the invisible along the groove. provide.
According to the configuration as described above, it is possible to install the fastener at an arbitrary position in the unobtrusive groove and attach the face material to the fastener. In other words, the degree of freedom in selecting the installation position of the fastener is not constrained by the position of the member on which the square or the like is installed, so that the shape and allocation of the face material can be freely performed without increasing the steel material cost. The degree can be increased.
In addition, since the fastener is attached involuntarily by a latching portion that engages with the groove portion, and can move relative to the invisible along the groove portion, the involuntary or invisible is installed due to an earthquake. Even if an interlayer displacement occurs in the member being mounted, the face material attached to the fastener can move relative to the member or the member without the filler. Therefore, it is possible to reduce the influence of the interlayer displacement received by the face material, and to prevent the face material from being damaged and dropped off.
Further, as described above, the shape of the finished surface material and the degree of freedom of allocation are high, so that this structure can be adopted as a standard without depending on the shape of the building. Therefore, it is possible to reduce the time and man-hours required for the determination and design of the face material mounting structure and the construction examination, that is, the construction cost can be reduced.

Arbitrary fasteners in the plurality of fasteners may be fixed so as to be immovable with respect to the eyes by a restraining member.
According to the above configuration, the fixed weight of the surface material attached to the fastener can be reliably supported by the fixed fastener. Therefore, the strength of the face material mounting structure can be increased.

The insignificant shape is a shape in which a cross-sectional contour shape is in a virtual rectangular shape, and a groove portion may be provided on a side surface opposite to the at least one side surface.
According to the above configuration, since fasteners can be installed on both the upper and lower sides of a single invisible, it is possible to improve the degree of freedom in design.

The said incoherence is installed between the verticals installed in the said structural frame, The said verticals may have the curved surface shape curved in the direction perpendicular | vertical with respect to the said face material.
According to the configuration as described above, in the present face material mounting structure, there is no restriction on the cross-sectional shape of the member extending in the vertical direction including the vertical, so that the vertical is easy to bend. It is possible to configure the upright to have a curved shape that curves in a direction perpendicular to the face material. In this case, it is possible for the face material to have a curved surface shape that is curved corresponding to the vertical, thereby further increasing the shape of the face material and the degree of freedom of the assignment.

If the fastener that is relatively movable with respect to the invisible and the fastener that is immovably fixed with respect to the invisible are fixed to the different face materials, the different face materials are relative to each other. Can be movable.
According to the above configuration, since the relative movement between the face materials is possible, the interlayer tracking performance of the face material can be further enhanced.

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to provide the face material attachment structure where the shape of a finishing surface material and the freedom degree of allocation are high.

  In a preferred mode, the construction cost can be reduced.

When the plurality of self-weight receiving fasteners 5 are fixed immovably, for example, when the same face material 7 is attached to these self-weight receiving fasteners 5, the plain 3 and the face material positioned between the self-weight receiving fasteners 5 When 7 is thermally stretched, due to the difference in thermal expansion coefficient between them, there is a possibility that stress is applied to the mesh 3 and the face material 7 to cause damage. Therefore, it is desirable that the other self-weight receiving fasteners 5 be in a state where they can be slightly moved during thermal expansion while being tightly installed by the seamless mounting bolts 21 and the seamless mounting nuts 22.

  FIG. 5 is a perspective view showing an installation state of the slide fastener 6 on the joint 3 in the face material mounting structure 1. The slide fastener 6 includes a main body 30, seamless mounting bolts / nuts 31, 32, and face material mounting bolts / nuts 33, 34.

  The main body 30 includes a bottom plate 30a and a side plate 30b, and the side plate 30b is joined to one side of the bottom plate 30a so as to be perpendicular to the bottom plate 30a. The main body 30 is a structural housing in which the bottom plate 30a straddles the upper first outer wall 3a and the upper second outer wall 3b and closes the upper groove portion 4a on the upper surface of the seamless 3, and the side plate 30b is seamless. It is arrange | positioned so that it may protrude on the further outer side of the surface on the opposite side. Two holes (not shown) are formed side by side in the direction in which the mesh 3 extends in a position corresponding to the upper groove portion 4a of the bottom plate 30a.

  The seamless mounting bolt 31 includes a head portion 31a and a male screw portion 31b. The seamless mounting bolt 31 is disposed so that the head portion 31a is positioned below and is stored in the upper groove portion 4a, and the male screw portion 31b faces upward and passes through the hole of the bottom plate 30a. The diameter of the head portion 31a is selected to be larger than the width of the opening of the upper groove portion 4a.

  A seamless mounting nut 32 is screwed to the male thread portion 31 b of the seamless mounting bolt 31. Since the head 31a of the seamless mounting bolt 31 has a diameter larger than the width of the opening of the upper groove 4a, there is no clearance between the head 31a of the seamless mounting bolt 31 and the seamless mounting nut 32. The upper first outer wall protrusion 3q of the upper first outer wall 3a of the eye 3 and the upper second outer wall protrusion 3r of the upper second outer wall 3b and the bottom plate 30a of the main body 30 are sandwiched. In the slide fastener 6, the seamless mounting bolt 31 and the seamless mounting nut 32 are joined moderately loosely. Further, the slide fastener 6 is not restrained by the restraining member from moving in the length direction of the intangible 3. In this manner, the slide fastener 6 is installed in the seamless 3 so as to be movable along the upper groove portion 4 a with respect to the seamless 3.

  A sliding material 35 is joined to the lower surface of the bottom plate 30 a of the main body 30 in order to smooth the relative movement between the mesh 3 and the sliding fastener 6. The sliding material 35 may be a stainless plate having a thickness of about 1 mm, for example, or may be polytetrafluoroethylene.

  A hole (not shown) is formed in the side plate 30b of the main body 30. The face material 7 is installed so as to be in contact with the outer surface of the side plate 30b, and is fixed by face material mounting bolts and nuts 33 and 34.

  As shown in FIG. 2, a seamless mounting member 8 is fixed on the inner outer walls 3 c and 3 d of the seamless 3, that is, on the structural housing side of the seamless 3. The seamless mounting member 8 includes a bottom plate 8a and a side plate 8b, and the side plate 8b is joined to one side of the bottom plate 8a so as to be perpendicular to the bottom plate 8a.

  A hole (not shown) is formed in the bottom plate 8a of the seamless mounting member 8. The bolt and nut 10 are used to connect the inner side of the seamless 3 through the hole in the same manner as the weight receiving fastener 5 described above. The first outer wall 3c and the inner second outer wall 3d are fixed tightly.

  The side plate 8b of the seamless mounting member 8 is fixed to the vertical 2 as shown in FIG.

  In contrast to the structure as shown in FIG. 2 constituted by the vertical 2, the seamless 3, the weight receiving fastener 5 and the slide fastener 6, the face material 7 is shown in FIG. To be attached. That is, in each blank 3, a slide fastener 6 that can move relative to the blank 3 and a self-weight receiving fastener 5 that is fixed so as not to move relative to the blank 3 are different from each other. These different face materials 7 are attached so as to be movable relative to each other.

  The face material 7 used in the present embodiment has a substantially square shape as shown in FIG. 1 and is attached so that one diagonal line of the face material 7 is parallel to the vertical direction. FIG. 6 is an enlarged view of a portion D-E in FIG. Here, attention is paid to the face material 7 a attached to the seamless 3 v shown in FIG. 6 via two weight receiving fasteners 5. The face material 7a is attached to the upper seamless 3w and the lower seamless 3x via the slide fastener 6.

  In FIG. 6, the face materials 7b, 7c, 7d, and 7e respectively located on the upper right, upper left, lower left, and lower right of the face material 7a have the same shape as the face material 7a, and are the same as the face material 7a. Arranged in the direction. Each of the side faces of the face material 7a and any of the side faces of the face materials 7b, 7c, 7d, and 7e are adjacent to each other with a certain interval between them. 7b, 7c, 7d, and 7e are provided side by side.

  The above joint is desirably about h / 100 or more, where h is the distance between the upper and lower joints 3. For example, when h is 1 m, the joint is desirably about 10 mm or more.

  The face materials 7b, 7c, 7d, and 7e are seamless with the slide members 6b, 6c, 6d, and 6e, respectively, with respect to the seamless 3v to which the face material 7a is attached via the weight receiving fastener 5. It is attached to be movable with respect to 3v. Further, the face materials 7b and 7c are respectively attached to the seamless 3w located on the first stage of the seamless 3v, and the face materials 7d and 7e are provided on the seamless 3x located one stage below the seamless 3v. Is attached through. In addition, the attachment method of the fasteners 5 and 6 and the face material 7 with respect to the one piece 3 is not restricted to this, It goes without saying that other various attachment methods can be considered unless it deviates from the meaning of the present invention. .

  Next, the operation and effect of the face material mounting structure 1 will be described.

  When an earthquake occurs and a lateral seismic force acts on the structural frame, the vertical 2 tilts obliquely due to the influence of the interlayer displacement accompanying the distortion of the structural frame. Accordingly, the eyes 3 located at different heights move relative to each other in the length direction of the eyes 3. Here, for example, let us consider a case where the invisible 3v shown in FIG. 6 moves relative to the invisible 3x, and the invisible 3w moves relative to the invisible 3v and the invisible 3x in the right direction. Even in the case of relative movement in the left direction, the same explanation can be made as follows.

  Since the face material 7a is tightly attached to the invisible 3v via the weight receiving fastener 5, the right side of the invisible 3v with respect to the invisible 3x moves in the right direction together with the invisible 3v. Try to move to. Here, the face material 7a is attached to the intangible 3x along the groove portion 4 via a slide fastener 6 that is movable relative to the invisible 3x. Therefore, the face material 7a can be moved relative to the invisible 3x, and thereby, it is possible to cope with the influence of the interlayer displacement acting on the face material 7a.

  Since the face materials 7d and 7e are tightly attached to the seamless 3x via the weight receiving fasteners 5, the face material 7a moves relative to the seamless 3x and at the same time with respect to the face materials 7d and 7e. However, they move in the same way. Since the relative movement direction is the right direction, the face material 7a moves so as to approach the face material 7e located at the lower right. Here, since joints with a constant interval are provided between the face material 7a and the face material 7e, even if relative movement of the face material 7a with respect to the face material 7e occurs, the face material 7a and the face material 7e does not touch.

  Further, since the face material 7a is attached to the intangible 3w via the slide fastener 6, when the relative movement of the invisible 3w with respect to the invisible 3v in the right direction occurs, the invisible 3w It is possible to perform relative movement with respect to the material 7a, and therefore it is possible to cope with the influence of the interlayer displacement acting on the face material 7a.

  Since the face materials 7b and 7c are tightly attached to the seamless 3w via the self-weight receiving fastener 5, the face materials 7b and 7c move relative to the face material 7a together with the seamless 3w. Since the direction of relative movement is the right direction, the face material 7c located at the upper left of the face material 7a moves so as to approach the face material 7a. Here, since joints with a constant interval are provided between the face material 7a and the face material 7c, even if relative movement of the face material 7c with respect to the face material 7a occurs, the face material 7a and the face material 7c does not touch.

  In this way, the slide fastener 6 is attached to the intangible 3 by the latching portion that engages with the groove portion 4, that is, the invisible attachment bolt 31, and moves relative to the invisible 3 along the groove portion 4. Therefore, even if an interlayer displacement occurs in the invisible 3 or the vertical 2 due to the earthquake, the face material 7 attached to the slide fastener 6 moves relative to the vertical 2 or the invisible 3. It is possible. Therefore, it is possible to reduce the influence of the interlayer displacement that the face material 7 receives, and to prevent the face material 7 from being damaged and dropped off.

  In addition to the above, different face materials 7 are attached to the self-weight receiving fastener 5 and the slide fastener 6 joined to the one piece 3 so that relative movement between the face materials 7 is possible. Therefore, the interlayer tracking performance of the face material 7 can be further enhanced. Since joints are provided between the face materials 7, the interlayer tracking performance is not impaired by the interference between the face materials 7.

  Further, the self weight receiving fastener 5 and the slide fastener 6 are installed at arbitrary positions of the groove portion 4 on the mesh 3 and the face material 7 is attached to the self weight receiving fastener 5 and the slide fastener 6. In addition, since the degree of freedom in selecting the installation position of the self-weight receiving fastener 5 and the sliding fastener 6 is not restricted by the position of the vertical 2, the shape of the face material 7 can be increased without increasing the steel material cost. The degree of freedom of assignment can be increased.

  Since the one piece 3 has the groove 4 on each side surface, the weight receiving fastener 5, the slide fastener 6, and the face material 7 can be arbitrarily installed on all sides of the piece 3. Therefore, the degree of freedom in design can be improved.

  In the present embodiment, the main bodies 20 and 30 of the self-weight receiving fastener 5 and the slide fastener 6 have an L-shape formed by joining two rectangular steel plates. If the fastener 6 has a configuration that can be attached to the seamless 3 by the seamless mounting bolts 21, 31, or a similar engagement or fitting shape, the main bodies 20, 30 are, for example, U-shaped. Any other shape and size such as I-shape may be used. That is, the fasteners 5 and 6 having various shapes can be joined to the seamless 3 and building materials having various specifications can be attached depending on the design of the fasteners 5 and 6.

  As described above, the shape of the face material 7 and the degree of freedom of the allocation are high, and the fasteners 5 and 6 can be attached to all the side surfaces of the seamless 3. Since it is possible to attach building materials with specifications, this structure can be adopted as a standard without depending on the shape of the building. Therefore, it is possible to reduce the time and man-hours required for the determination and design of the face material mounting structure and the construction examination, that is, the construction cost can be reduced.

  The self-weight receiving fastener 5 is fastened to the groove 3 of the seamless 3 by a seamless mounting bolt 21 and a seamless mounting nut 22. As a result, the weight of the face material 7 attached to the weight receiving fastener 5 can be reliably supported.

  As shown in FIG. 4 (b), the locking portion 20d of the self-weight receiving fastener 5 and the locking portion 3u of the upper outer walls 3a, 3b of the seamless 3 are fitted, so that the locking portion 20d It is possible to resist external forces such as seismic force, wind load, and gravity acting in a direction perpendicular to the direction in which the concave and convex ridges extend.

  As described above, the self weight receiving fastener 5 and the seamless 3 can increase the strength of the face material mounting structure.

  Further, the uneven shape of the engaging portion 3u of the seamless 3 is so that the contact area with the sliding material 35 installed on the bottom surface of the main body 30 of the sliding fastener 6 in contact with the upper surface shown in FIG. 5 is reduced. Works. Accordingly, the frictional force acting between the seamless 3 and the slide fastener 6 can be reduced, and the slide fastener 6 can be moved smoothly, thereby further improving the interlayer tracking performance of the face material 7. It becomes possible.

  Next, the 1st modification of the face material attachment structure 1 shown as the said embodiment is demonstrated using FIG. The difference between the first modification and the face material mounting structure 1 is that the cross-sectional shape of the eye is different.

  FIG. 7 is a cross-sectional view of the eyeless 40 in the first modification. The intangible 40 does not have a groove corresponding to the lower groove 4c of the insignificant 3 shown in FIG. 3. Instead, the lower surface of the invisible 40 has a width equivalent to the width of the invisible 40. It is comprised by the one lower outer wall 40a which has. More specifically, in the intangible 40, the inner inner wall 3j and the outer inner wall 31 in the unmesh 3 do not have the inner inner wall lower projecting portion 3n and the outer inner wall lower projecting portion 3o, respectively. The lower ends of the inner walls 31 are connected and terminated on the upper surface of the lower outer wall 40a. Further, the seamless 40 does not have the lower first outer wall 3e and the lower second outer wall 3f connected to the inner inner wall lower protruding portion 3n, the outer inner wall lower protruding portion 3o.

  The inner side second outer wall 3d and the outer first outer wall 3g are respectively connected to the lower outer wall 40a at the ends of the lower outer wall 40a in the direction of the structural casing, that is, the inner side and the outer side opposite to the inner side. They are joined so as to be vertical.

  With the above configuration, the eyeless 40 has a shape in which the cross-sectional contour shape is in the virtual rectangular shape, like the eyeless 3. That is, the upper first outer wall 3a and the upper second outer wall 3b are on the upper surface, the inner first outer wall 3c and the inner second outer wall 3d are on the inner surface on the structure housing side, the lower outer wall 40a is on the lower surface, and the outer first outer wall. When it is considered that 3g and the outer second outer wall 3h correspond to outer surfaces opposite to the structural housing, each outer wall of the intangible 40 is formed by a top surface, an inner surface, an outer surface, and a lower surface. It has a shape along.

  The inner groove portion 4b of the seamless 40 is formed by the respective surfaces of the inner inner wall 3j on the bottom surface and the upper second outer wall 3b and the lower outer wall 40a on the side surfaces. Further, the outer groove portion 4d of the seamless 40 is formed by the respective surfaces of the outer inner wall 3l at the bottom surface and the upper first outer wall 3a and the lower outer wall 40a at the side surfaces.

  In the face material mounting structure 1 shown in FIG. 1, the same effect as that of the above embodiment can be obtained even if the seamless 40 is used instead of the seamless 3. The seamless 40 does not have the lower groove 4c of the seamless 3 and the fasteners 5 and 6 cannot be installed on the lower surface of the seamless. For example, the fastener installed in the other grooves 4a, 4b, and 4d. By deforming the shapes of 5 and 6 so that the side plates 20b and 30b on which the face material 7 is installed shown in FIGS. It is possible to attach the positioned face material 7 to the mesh 40. Alternatively, in a state where the intangible 40 shown in FIG. 7 is rotated 90 ° clockwise on the paper surface, that is, not on the lower side but on the outer side opposite to the structural housing, the groove portion is not positioned, You may arrange. In any case, since the fasteners 5 and 6 having various shapes can be joined to the seamless 40, the effect of the above embodiment is impaired when the number of the groove portions 4 is reduced from the seamless 3. I can't.

  Next, the 2nd modification of the face material attachment structure 1 shown as the said embodiment is demonstrated using FIG. The difference between the second modified example and the face material mounting structure 1 is that the cross-sectional shape of the mesh 50 is different.

  The intangible 50 does not have the inner groove portion 4b and the outer groove portion 4d that the intangible 3 shown in FIG. 3 has. The outer wall of the mesh 50 includes an upper first outer wall 50a and an upper second outer wall 50b positioned on the upper side, an inner outer wall 50c positioned on the inner side of the face material mounting structure facing the structure housing, and a lower first positioned on the lower side. One outer wall 50d, a lower second outer wall 50e, and an outer outer wall 50f located on the outer side of the face material mounting structure on the side opposite to the structural housing are provided. The inner wall includes a main inner wall 50g, an inner inner wall 50h, and an outer inner wall 50i.

  An inner inner wall 50h and an outer inner wall 50i are joined to both ends of the horizontally located main inner wall 50g so as to be perpendicular to the main inner wall 50g.

  The upper first outer wall 50a is joined to the upper end of the outer inner wall 50i so as to be perpendicular to the outer inner wall 50i. The upper first outer wall 50a protrudes from the joint position with the outer inner wall 50i toward the structural housing, thereby forming an upper first outer wall protrusion 50j. An outer outer wall 50f is joined to an end of the upper first outer wall 50a opposite to the upper first outer wall protrusion 50j so as to be perpendicular to the upper first outer wall 50a.

  The upper second outer wall 50b is joined to the upper end of the inner inner wall 50h so as to be perpendicular to the inner inner wall 50h. The upper second outer wall 50b protrudes from the joint position with the inner inner wall 50h to the opposite side of the structural housing, thereby forming the upper second outer wall protrusion 50k. An inner outer wall 50c is joined to an end of the upper second outer wall 50b opposite to the upper second outer wall protrusion 50k so as to be perpendicular to the upper second outer wall 50b.

  The lower first outer wall 50d is joined to the lower end of the inner inner wall 50h so as to be perpendicular to the inner inner wall 50h. The lower first outer wall 50d protrudes from the joint position with the inner inner wall 50h to the opposite side of the structural housing, thereby forming a lower first outer wall protruding portion 50l. An inner outer wall 50c is joined to an end of the lower first outer wall 50d opposite to the lower first outer wall protrusion 50l so as to be perpendicular to the lower first outer wall 50d.

  The lower second outer wall 50e is joined to the lower end of the outer inner wall 50i so as to be perpendicular to the outer inner wall 50i. The lower second outer wall 50e protrudes from the joint position with the outer inner wall 50i toward the structural housing, thereby forming a lower second outer wall protrusion 50m. An outer outer wall 50f is joined to an end of the lower second outer wall 50e opposite to the lower second outer wall protrusion 50m so as to be perpendicular to the lower second outer wall 50e.

  With the above configuration, the eyeless 3 has a shape in which the cross-sectional contour shape is in the virtual rectangular shape. That is, the upper first outer wall 50a and the upper second outer wall 50b are on the upper surface, the inner outer wall 50c is on the inner surface on the structure housing side, the lower first outer wall 50d and the lower second outer wall 50e are on the lower surface, and the outer outer wall 50f. Is considered to correspond to the outer surface on the opposite side of the structural housing, each outer wall of the intangible 50 is formed by an upper surface, an inner surface, an outer surface, and a lower surface, and has a shape along a rectangular contour shape. Yes.

  The invisible member 50 has an upper groove 51a on the upper surface. The upper groove 51a is formed by the respective surfaces of the main inner wall 50g on the bottom surface and the inner inner wall 50h and the outer inner wall 50i on the side surfaces. The upper groove 51a communicates with the outside through an opening located on the upper surface of the mesh 50. From both ends of the opening, an upper first outer wall protrusion 50j and an upper second outer wall protrusion 50k protrude toward the opening, and the opening is narrower than the internal space of the upper groove 51a. Yes.

  The invisible member 50 has a lower groove 51b on the lower surface. The lower groove 51b is formed by the respective surfaces of the main inner wall 50g on the bottom surface and the inner inner wall 50h and the outer inner wall 50i on the side surfaces. The lower groove 51b communicates with the outside through an opening located on the lower surface of the mesh 50. From both ends of the opening, a lower first outer wall protrusion 50l and a lower second outer wall protrusion 50m protrude toward the opening, and the opening is narrower than the inner space of the lower groove 51b. It has become.

  Each opening part of the upper side groove part 51a and the lower side groove part 51b is comprised so that it may have a comparable magnitude | size. The size of the opening is determined by the specifications of the fastener to be attached.

  Concave ridges extending in the length direction of the intangible 3 are formed on a part of each outer surface of each outer wall corresponding to the side surface having the groove 51. This concave ridge acts as the locking portion 50n when the self-weight receiving fastener 5 is installed.

  In the face material mounting structure 1 shown in FIG. 1, the same effect as that of the above embodiment can be obtained even if the seamless 50 is used instead of the seamless 3. As described in the first modification, since it is possible to join the fasteners 5 and 6 having various shapes to the seamless 50, the number of the groove portions 50 is smaller than that of the seamless 3, so that The effects of the embodiment are not impaired.

  Next, the 3rd modification of the face material attachment structure 1 shown as the said embodiment is demonstrated using FIG. The difference between the third modification and the face material mounting structure 1 is that the cross-sectional shape of the intangible 60 is different.

  The blank 60 shown in FIG. 9 has a cross-sectional shape close to the blank 50 shown in FIG. 8 as a second modification. That is, the difference between the seamless pattern 50 and the seamless pattern 60 is that the seamless pattern 60 does not have the inner outer wall 50c and the outer outer wall 50f of the seamless pattern 50. Therefore, the seamless 60 has groove portions 51 a and 51 b at the same position as the seamless 50.

  In the face material mounting structure 1 shown in FIG. 1, the above-described implementation can be performed in the same manner as the case of the feature 50 in the second modified example, even if the feature 60 having the above configuration is used instead of the feature 3. Needless to say, the same effect as that of the embodiment can be obtained.

  Next, the 4th modification of the face material attachment structure 1 shown as the said embodiment is demonstrated using FIG.

  In the fourth modified example, unlike the face material mounting structure 1, the stand 70 has a curved shape that curves in a direction perpendicular to the face material 72.

  In the face material mounting structure 1 in the embodiment shown in FIG. 1, there is no restriction on the cross-sectional shape of the member extending in the vertical direction including the vertical 2, so that the vertical 2 is formed into a cross-sectional shape that is easy to bend. The vertical 2 can be configured to have a curved shape that curves in a direction perpendicular to the face material 7. In this case, in the fourth modified example, the stand 70 has a curved curved surface shape corresponding to the face material 72, thereby further increasing the shape of the face material 72 and the degree of freedom of allocation. Can be increased.

  It goes without saying that the fourth modification has the same effect as that of the above embodiment.

  Next, the 5th modification of the face material attachment structure 1 shown as the said embodiment is demonstrated using FIG.

  In the fifth modified example, unlike the face material mounting structure 1 shown in FIG. 1, the intangible 80 is directly installed on the structural housing 81 without using a vertical.

  The invisible 80 has a shape close to the invisible 40 shown as the first modification shown in FIG. The difference between the invisible 80 and the invisible 40 is that, in the cross-sectional shape of the invisible 80, both ends of the outer wall 80a corresponding to the lower outer wall 40a of the invisible 40 are the inner second outer wall 3d and the outer first outer wall 3g. It extends beyond and forms the rib 80b.

  The intangible 80 is installed with the outer wall 80a vertical so that the outer wall 80a contacts the vertical wall surface of the structural housing 81. The intangible 80 is fixed to the structural housing 81 by a bolt 82 that passes through a hole (not shown) formed in the rib 80b.

  In the fifth modification, since the invisible 80 can be installed without using a vertical, the degree of freedom in selecting the installation position of the invisible 80 is improved, and thereby the shape and layout of the face material are improved. The degree of freedom can be further increased. Moreover, since it is not necessary to use a vertical, the steel material cost can be further reduced.

  It goes without saying that the fifth modified example has the same effect as the above embodiment.

  In addition, in said embodiment and modification, the face material used may be glass, ALC, an extrusion-molded cement board, a stone, etc. other than an aluminum panel. Moreover, what is attached invisible is not limited to the face material, and for example, a decoration having a three-dimensional shape may be attached.

  In the above embodiment, the fasteners 5 and 6 are joined to the seamless upper groove 4a and the lower groove 4c, but may be attached to the inner groove 4b or the outer groove 4d. As described above, since the fasteners 5 and 6 having various shapes can be attached to the intangible 3, the attachment positions of the fasteners 5 and 6 can be arbitrarily changed.

  Further, in the above-described embodiments and modifications, the faceless mounting nut, the nut of the restraining member, and the surface material for the self-weight receiving fastener and the sliding fastener are used when the self-weight receiving fastener and the sliding fastener are attached invisible. Each nut of the face material attaching nut used when attaching the nut may be a loosening prevention specification.

  Moreover, you may use said embodiment and a modification in combination with each other. For example, in the fourth modification, the intangible 40 shown in FIG. 7 may be used as the first modification.

  The preferred embodiments of the present invention have been described in detail above. However, those skilled in the art will understand that various modifications and equivalent embodiments are possible from this. .

  Therefore, the scope of rights of the present invention is not limited to this, and various modifications and improvements of those skilled in the art using the basic concept of the present invention described in the claims are also included in the present invention.
