Description

  The present invention relates to an outer wall panel mounting structure in which a side end portion of an outer wall panel is fixed in a concave groove formed on a side surface of a column frame made of steel.

  As a standing structure of outer walls and partition walls in multistory parking lots, factories, etc., the side wall of the outer wall panel is fitted into a recessed groove of H-shaped steel or grooved steel standing upright as a support frame and fixed with various members Such a structure is known (see, for example, Patent Document 1).

  FIG. 7A is a plan view showing a conventional outer wall panel mounting structure using H-shaped steel as a support frame, which is also disclosed in Patent Document 1. FIG.

  In this example, the outer wall panel 101 is fixed with an L-shaped angle 120. Specifically, two L-shaped angles 120 arranged in both concave grooves 111, 111 formed by a pair of flanges 112, 112 of the H-shaped steel 110 and the central abdomen 113 sandwich the central abdomen 113 of the H-shaped steel 110. By fastening with bolts 140 and nuts 141, a gap 111a is formed between the L-shaped angle 120 and the flange 112, and the outer wall panel 101 can be fitted and fixed in the gap 111a.

  According to this mounting structure, it is excellent in that there are few members to use, but it is necessary to open a bolt insertion hole 114 in the central abdomen 113 of the H-shaped steel 110 in advance in accordance with the thickness dimension of the outer wall panel 101 to be mounted. Since the construction takes time and each member has manufacturing tolerances, the outer wall panel 101 cannot be firmly fixed to the H-shaped steel 110 (becomes loosely fitted) and the width of the gap 111a is small. In some cases, the outer wall panel 101 cannot be press-fitted, and the width dimension of the gap 111 a or the width dimension of the side end portion 101 a of the outer wall panel 101 must be adjusted in the field.

  On the other hand, FIG. 7B shows a conventional outer wall panel mounting structure in which the outer wall panel 101 is fixed using the H-shaped fixture 130 and the L-shaped spring steel 135 in the concave groove 111 of the H-shaped steel 110. It is a top view.

  In this example, one flange 131 of the H-shaped fixture 130 is attached to the wall surface of the outer wall panel 101 with a screw, and between the other flange 131 of the H-type fixture 130 and the other flange 112 of the H-shaped steel 110. The L-shaped spring steel 135 is interposed between the two.

  According to this structure, since the L-shaped spring steel 135 is used, the outer wall panel 101 can be fixed to such an extent that it does not rattle. Of course, there is no fear that the outer wall panel 101 cannot be fitted into the concave groove 111.

However, in the mounting structure of FIG. 7B, the manufacturing tolerances of the three members of the H-shaped steel 110, the outer wall panel 101, and the H-shaped fixture 130 are combined, so depending on the combination, only the L-shaped spring steel 135 is used. These tolerances may not be absorbed. In particular, the tolerance between the flanges 112 and 112 of the H-shaped steel 110 is large, and the total value of the tolerance may be increased.

  Further, in this mounting structure, since the H-shaped fixing member 130 is screwed to the outer wall panel 101, there is a problem that a hole is opened in the outer wall panel 101, thereby causing deterioration earlier or worsening appearance.

JP 2000-129635 A

  The present invention provides an outer wall panel mounting structure that can absorb the manufacturing tolerance of each member when mounting the outer wall panel in the recessed groove of the support frame, and can fix the outer wall panel without wobbling, and can perform construction work quickly. It is to provide. It is another object of the present invention to eliminate the need for processing such as opening a bolt insertion hole in the steel plate and to prevent the outer wall panel from being damaged such as screw holes.

In order to achieve the above object, the outer wall panel mounting structure according to claim 1 is an outer wall panel in which a side end of the outer wall panel is fixed in a concave groove formed in a side surface of a column frame made of steel.

  According to the mounting structure of the outer wall panel according to claim 1, the outer wall panel is configured to be fixed by pressing the outer wall panel with a bolt body through a buffer plate that is elastically deformable in the thickness direction. The manufacturing tolerance of the support frame into which the bolt is inserted can be absorbed by the degree of screwing of the bolt body, and the buffer plate is interposed, so that the manufacturing tolerance can also be absorbed by its elastic force. Therefore, not only can the outer wall panel be attached, but it can be securely fixed to eliminate rattling after construction.

  Moreover, since it is not necessary to process a bolt insertion hole etc. in a shape steel, a quick and efficient construction is realizable. Furthermore, since it is the structure which does not use a screw for fixing an outer wall panel, there is no possibility that a crack, such as a hole by a screw stop, will be attached to an outer wall panel, and it can prevent that an outer wall panel deteriorates by it. Moreover, since the surface is not damaged, the appearance of the surface of the outer wall panel is not deteriorated and can be reused.

In addition, since the fixing tool is formed of a folded piece having a press-fitting gap, the fixing tool can be easily mounted and fixed to the side wall of the concave groove, and a quick construction can be realized. Further, since the bolt screw hole is formed in the vicinity of the folded base portion of the folded piece, the outer wall panel can be securely fixed only by screwing and screwing the bolt body.

Furthermore, the vicinity of the turn-up base of the turn-up piece that constitutes the fixture has a structure that is bent stepwise on the outer wall panel side, so the bolt head is on the outside of the side wall of the support frame when the bolt body is attached. Protruding can be prevented.

According to the outer wall panel mounting structure of the second aspect , since the buffer plate has a configuration in which the side end of the plate material is folded back, the buffer plate can be easily manufactured, and the construction cost can be kept low.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  The outer wall panel mounting structure of the present invention is for fixing and fixing an outer wall panel in a concave groove formed on a side surface of a column frame made of steel. For this purpose, a buffer plate, a fixture and a bolt body are used. .

In the following, two types of embodiments (reference examples and examples) in which the structure and shape of the fixture are different will be described. In these embodiments, H-shaped steel is used as the support frame. However, it may be any steel that has a groove formed on any side surface, and may be, for example, groove steel.

  In addition, as the outer wall panel, a material in which the core material is made of foamed resin and the outer shell is formed of a metal plate such as an aluminum plate is preferably used, but other materials such as a cement plate may be used.

FIG. 1 is an exploded perspective view showing a mounting structure of an outer wall panel according to a first embodiment (reference example) of the present invention, and shows a state before mounting of the outer wall panel. FIG. 2 is a perspective view showing the outer wall panel after being mounted according to the embodiment. FIG. 3A is a plan view showing a mounting and fixing state of the outer wall panel, and FIGS. 3B and 3C are plan views of a buffer plate and a fixture used for mounting and fixing the outer wall panel.

  The H-shaped steel 10 used as a support frame is composed of a pair of flanges 12 and 12 and a central abdomen 13, and is formed in an H shape in a plan view. In each of them, a concave groove 11 is formed having a bottom portion formed by the central abdomen 13 and a side wall formed by both flanges 12 and 12.

  The outer wall panel 1 is arranged in an upright state so that the side end portion 1 a is brought into contact with the inner surface of the side wall formed by one flange 12 of the concave groove 11. Alternatively, the plurality of outer wall panels 1 may be actually joined at the upper and lower ends and stacked to stand in the recessed groove 11.

  On the other hand, the fixture 30 for fixing the outer wall panel 1 with the bolt body 40 is fitted and fixed to the flange 12 forming the other side wall of the concave groove 11.

  The fixture 30 is made of a metal folded piece having a first piece 31 and a second piece 32 having a press-fitting gap 33a for the flange 12, and the first piece 31 has a flat plate shape. The second piece 32 is bent at several points, and the gap between the second piece 32 and the first piece 31 is the narrowest at the center, and is widened at the tip and the vicinity of the folded base 35a.

  The gap interval at the center is smaller than the thickness dimension of the flange 12, and the fixing tool 30 can be press-fitted to the flange 12 and cannot be easily removed. Further, the distal end portion of the second piece 32 constitutes a guide piece 33b formed so that the gap opening is widened, so that the second piece 32 can be easily attached to the flange 12.

  A bolt hole 35b is formed in the vicinity of the folded base portion 35a of the first piece 31 and the second piece 32, and at least one of them is a bolt screwing hole 35c. In the illustrated example, the bolt hole 35b of the first piece 31 is a bolt screw hole 35c, but the reverse may be possible. Further, if the first piece 31 and the second piece 32 are processed so as to be in parallel with each other in the vicinity of the folded base portion 35a, any of the bolt holes 35b and 35b may be constituted by a bolt screw hole 35c. In consideration of formation errors, it is desirable that one bolt hole 35b be a slightly larger bolt insertion hole without a thread groove as in the present embodiment.

  Thus, the fixture 30 is functionally pressed by the bolt body 40 against the fitting portion 33 that is fitted to the side wall of the concave groove 11 by the press-fitting gap 33 a and the folded elastic piece 22 of the buffer plate 20. It is the structure provided with the bolt stop part 35 for doing.

  The fixing tool 30 is firmly fixed to the H-shaped steel 10 by hitting the folded portion with, for example, a hammer or the like so that the second piece 32 is elastically deformed and spread over the flange 12. Note that FIG. 3A shows the fitting state of the fixing tool 30, and shows the return state (not fitted state) of the second piece 32 by a two-dot chain line.

  Further, the buffer plate 20 is disposed so as to be in contact with the surface of the outer wall panel 1 disposed on one side wall side in the concave groove 11.

  The buffer plate 20 is formed by folding back side edges of a plate material made of metal or the like, and the main body piece 21 and the folded elastic piece 22 are spread in an acute angle so as to be elastically deformable in the thickness direction. It has become. The opening angle is determined by the length of the bolt body 40 and the like. Further, an anti-slip piece 23 that is further bent outward is formed at the tip of the folded elastic piece 22.

  As described above, when each member is placed in or attached to the concave groove 11 of the H-shaped steel 10, the bolt body 40 is inserted into the bolt screwing hole 35c of the fixture 30 and is screwed, thereby leading the tip of the bolt body 40. Is pressed so that the folded elastic piece 22 of the buffer plate 20 is elastically deformed, so that the outer wall panel 1 is fixed in a non-moving state. In addition, it is desirable that the fixture 30 is attached to a plurality of locations at a predetermined interval with respect to the overall height.

  Further, in the illustrated example, a nut 41 is screwed to the bolt body 40 outside the second piece 32 of the fixture 30, and the bolt base 40 and the nut 41 are used to tighten the turn-up base portion vicinity 35 a of the fixture 30. I have to. This prevents the screw body 40 from loosening.

  According to such an outer wall panel mounting structure, the outer wall panel 1 is pressed and fixed by the bolt body 40 via the buffer plate 20, so that the outer wall panel 1 and the H-shaped steel 10 into which the outer wall panel 1 is fitted. Can be absorbed by the elastic force of the buffer plate 20. As a result, the outer wall panel 1 will not rattle after construction due to wind, vibration, or the like. Since the elastic urging force of the buffer plate 20 is always applied after the construction, loosening of the bolt body 40 can be prevented.

  Moreover, since it is not the structure which bolts with respect to the H-shape steel 10, it is not necessary to process a shape steel, an operation | work effort can be saved and work efficiency can be raised.

  Furthermore, since it is the structure which does not use a screw for fixation of the outer wall panel 1, there is no possibility of a damage | wound, such as a hole by screwing, and it can prevent the deterioration of the outer wall panel 1 from advancing. Moreover, since the surface is not damaged, the outer wall panel 1 can be reused.

  Furthermore, since the buffer plate 20 is arranged on the surface of the outer wall panel 1, the surface of the outer wall panel 1 is not directly pressed by the tip of the bolt body 40, so that the panel surface may be partially recessed. Absent. Thus, since it is the structure which interposes the buffer plate 20, it is not necessary to make the surface of the outer wall panel 1 hard, and what made the surface a little soft as an outer wall panel can be used.

  Since the surface of the buffer plate 20 is pressed by the bolt body 40, it is desirable to use a hard material, but at least the buffer plate is formed of a metal plate and the back side is made of elastically deformable rubber. Can also be used.

  Further, since the anti-slip piece 23 is formed at the tip of the folded elastic piece 22 of the buffer plate 20 over the entire height, even if the tip of the bolt body 40 is displaced toward the bottom of the concave groove 11, the anti-slip piece 23 is caught. Although it does not come off, an anti-slip portion such as fine irregularities may be provided on the outer surface of the folded elastic piece 22 of the buffer plate 20 in order to prevent further displacement.

Next, a second embodiment (example) of the present invention will be described.

  FIG. 4 is an exploded perspective view showing the mounting structure of the outer wall panel according to the second embodiment of the present invention, and is a diagram showing the state before mounting the outer wall panel. FIG. 5 is a perspective view showing the outer wall panel after being mounted according to the embodiment. FIG. 6A is a plan view showing a mounting and fixing state of the outer wall panel, and FIGS. 6B and 6C are plan views of a buffer plate and a fixture used for mounting and fixing the outer wall panel.

  The outer wall panel mounting structure of the present embodiment is to fix the same outer wall panel 1 as in the first embodiment by using the H-shaped steel 10, the buffer plate 20, the fixture 30, and the bolt body 40.

  Since the H-shaped steel 10 used as the support frame is the same as that of the first embodiment, its structure is denoted by the same reference numerals and description thereof is omitted.

  As in the first embodiment, the outer wall panel 1 is disposed in an upright state by being attached to one side wall (flange 12) in a concave groove 11 formed on a side surface of the H-shaped steel 10.

  Further, the buffer plate 20 is the same as that of the first embodiment, but in the present embodiment, as shown in FIG. 6A, the bolt body 40 is screwed in an oblique direction from the outside to the inside of the groove 11. Since the configuration is fixed, the opening angle between the main body piece 21 and the folded elastic piece 22 is adjusted so that it is slightly opened in consideration of the screwing angle of the bolt body 40.

  On the other hand, the fixture 30 is the same as that of the first embodiment in that it is fitted and fixed to the flange 12 that forms the other side wall of the concave groove 11, but the shape thereof is different from that of the first embodiment. Different.

  In other words, the fixture 30 is formed of a metal folded piece having a first piece 31 and a second piece 32 having a press-fitting gap 33a with respect to the flange 12, and functionally, a concave groove is formed by the press-fitting gap 33a. 11 is provided with a fitting portion 33 that is fitted on the side wall of the eleventh side, and a bolting portion 35 that is pressed against the folded elastic piece 22 of the buffer plate 20 by the bolt body 40.

  In the fitting portion 33, the first piece 31 and the second piece 32 are both formed in a substantially flat plate shape, and the press-fitting gap 33a between the first piece 31 and the second piece 32 is the narrowest at the center. Is formed.

  The press-fitting gap 33a in the central portion is smaller than the thickness dimension of the flange 12, and the fixing tool 30 can be press-fitted to the flange 12 and cannot be easily removed. Further, the distal end portion of the second piece 32 constitutes a guide piece 33b formed so that the gap opening is widened, so that the second piece 32 can be easily attached to the flange 12.

  Further, the bolting portion 35 is bent at a substantially right angle in the direction of the outer wall panel 1 from the end portion on the folding side of the fitting portion 33, and further bent in a direction away from the groove 11. As shown in FIG. In the bolting portion 35, a slight gap on the return molding is formed between the first piece 31 and the second piece 32, but it is desirable to overlap in a close contact state in order to make it stronger.

  Further, a bolt hole 35b is formed in the first piece 31 and the second piece 32 in the vicinity of the folded base portion 35a of the bolt fastening portion 35, and at least one of them is a bolt screwing hole 35c. In the illustrated example, the bolt hole 35b of the first piece 31 is a bolt screw hole 35c, but the reverse may be possible. In addition, any of the bolt holes 35b and 35b may be constituted by a bolt screw hole 35c, but it is desirable that one of the bolt holes 35b and 35b is a slightly larger bolt insertion hole in which no thread groove is cut in consideration of formation errors. .

  Thus, the fixing tool 30 is press-fitted to the flange 12 so that the second piece 32 is elastically deformed and spreads, and is firmly fixed to the H-shaped steel 10. Note that FIG. 6A shows the fitting state of the fixing tool 30, and the return state of the second piece 32 is shown by a two-dot chain line.

  When the bolt body 40 is screwed into the bolt screwing hole 35c of the fixture 30 with each member placed in or attached to the concave groove 11 of the H-shaped steel 10 as described above, the tip of the bolt body 40 is buffered. The folded elastic piece 22 of the plate 20 is pressed so as to be elastically deformed, and by doing so, the outer wall panel 1 is fixed so as not to move. In addition, it is desirable that the fixture 30 is attached to a plurality of locations at a predetermined interval with respect to the overall height.

  In the illustrated example, a nut 41 is screwed to the bolt body 40 outside the second piece 32 of the fixture 30. This prevents the screw body 40 from loosening.

  Thus, also in this embodiment, since it is the structure which presses and fixes the outer wall panel 1 with the volt | bolt body 40 using the buffer plate 20 and the fitting type fixing tool 30 similarly to 1st Embodiment, it is 1st implementation. The same effect as the form is produced.

  Moreover, in this embodiment, since the fixing tool 30 is the shape which distribute | arranges the bolt stop part 35 (bolt hole 35b) of the return | turnback base part vicinity 35a to the position close | similar to the outer wall panel 1, when a bolt body 40 is attached, bolt head Can be prevented from projecting outside the side wall of the H-shaped steel 10, and a person can be prevented from being caught.
