  By the way, in the prior art, the plate-like body is disposed between the flanges of each column so that each side portion is received between the flanges of each column and overlaps with each other in a relatively long range. It was hung between both supports.

  However, there is a problem that it takes a lot of time and labor to lift and suspend the plate-like body. Further, there is a problem that the plate-like body cannot be disposed between the two columns unless a space for lifting the plate-like body can be secured above the two columns.

  An object of the present invention is to provide an attachment device that makes it possible to arrange the plate-like body between both struts without hanging from above the both struts.

An attachment device according to the present invention is an attachment device for attaching a plate-like body having a side portion received between both flanges of a column to a column having a pair of opposing flanges extending in the vertical direction and a web connected to both flanges. there are, said plate-like body extending portion from the side Ru extend toward the web of the posts when secured to at least one plate member fixable to the plate-like body, from said該伸length portion An extension portion extending toward one flange of the column and in contact with the one flange, at least one plate member having one surface in contact with the side portion of the plate-like body, and the plate member Fixing means for fixing the plate-like body to the support column.

It said fixing means, pressing means for pressing the sides of the plate-like member on the one hand of a flange of the other side of the flange is disposed between the flange and the plate member of the other side of the strut as a reaction force support It is. Said pressing means, said plate and a nut fixed to the other surface of the member, the shaft portion is screwed into the nut, the head upon attachment of the plate-like member to the struts toward the other side of the flange It is made up of bolts.

The plate member is formed by a bolt that penetrates a bolt hole that is a long hole having a planar shape elongated in a direction perpendicular to the web of the support column, and a nut screwed to the bolt. It is fixed to the body .

  According to the present invention, the plate-like body is disposed between a pair of struts with both sides thereof being received between both flanges of both struts, and each side portion of the plate-like body is disposed on the plate-like body. It is fixed to both flanges of each column by the fixing means via the fixed plate member. At this time, each plate member is integrated with the side portion of the plate-like body and extends toward the web of each column.

  In the present invention, the plate member can be fixed to the plate-like body, and the width dimension of the plate-like body is substantially different before and after fixing, that is, before fixing is small. It may have a width dimension and may have a large width dimension after fixing.

  When the plate-like body in a state of a small width dimension in which the plate member is not fixed is disposed between both pillars, one side of the plate-like body is first placed between both flanges of one pillar. And then propel it toward the web, the other side can now be guided between the flanges of the other strut. For this reason, the plate-like body can be disposed between the two support columns without depending on the conventional suspension work of the plate-like body from the upper position of the two support columns.

  In addition, when the plate member is fixed to the plate-like body and the width dimension of the plate-like body is substantially increased after the plate-like body is arranged between the two pillars, The overlapping length of each side part of the plate-like body, that is, the wrap length is increased. As a result, the plate-like body can be reliably prevented from coming out from between both flanges of each column.

  Furthermore, the fixing means for fixing the plate-like body to each column is composed of the pressing means, so that, for example, each bolt hole in which a bolt for fixing the plate-like body to each column is arranged. The plate-like body can be fixed to each of the columns without having to be formed on the column, and without causing the fixing means to protrude outside the space defined by both flanges of each column. For this reason, time and labor for forming a bolt hole in each support are not required. In addition, the plate-like body can be fixed to each column more economically. Furthermore, since the fixing means does not protrude outside the space between the two flanges of each column, there is little risk that passers-by will catch clothes, which is also preferable in terms of appearance.

  When the fixing means is composed of the pressing means, the plate member fixed to the plate-like body by providing the plate member with the extension portion in contact with one flange of each column. It can be pressed against one flange of the column by the pressing means. Thereby, it is possible to more reliably prevent the plate-like body from coming out from between both flanges of each column.

  Further, the bolt hole in which the bolt for fixing the plate member to the plate-like body is arranged is a long hole having an elongated planar shape in a direction perpendicular to the web of each column, The plate member can be moved in a direction perpendicular to the web of each column with respect to the plate-like body. Thereby, the position of the said plate member can be adjusted with respect to the said plate-shaped object, and the substantial width dimension of the said plate-shaped object can be adjusted according to the space | interval of both support | pillars.

  As shown in FIGS. 1 and 2, a plate-like body 14 is disposed between a pair of struts 10 and 12 that are spaced apart from each other, and the plate-like body is fixed to each of the struts 10 and 12 by an attachment device 16. ing.

  Each support | pillar 10 and 12 consists of H-section steel. One strut 10 has a pair of opposing flanges 18 and 20 extending in the vertical direction and a web 22 connected to both flanges, and the other strut 12 has a pair of opposing flanges 24 and 26 extending in the vertical direction and A web 28 is connected to both flanges. The plate-like body 14 is received between the flanges of the support columns 10 and 12 at the side portions 30 and 32 thereof.

  As shown in FIG. 3, the plate-like body 14 connects the front plate 34 made of a sound absorbing material, the back plate 38 that forms an air layer 36 between the front plate, the front plate 34, and the back plate 38. Side plate 40. The front plate 34 is in contact with one flange 24 of the column 12 at the side portion 32 of the plate-like body 14. The side plate 40 has an end portion 42 in contact with the back plate 38, and a nut 44 is fixed to the end portion by welding, and a bolt hole 46 facing the nut is provided. The back plate 38 is provided with bolt holes 48 facing the bolt holes 46.

  The attachment device 16 includes a plate member 50 that can be fixed to the plate-like body 14, and fixing means 52 that fixes the plate-like body 14 to the column 12 via the plate member.

  Bolt holes 54 are provided in the plate member 50. The plate member 50 is fixed to the plate-like body 14 by screwing bolts 54, bolt holes 48, and bolts 56 passing through the bolt holes 46 into the nuts 44. The bolt hole 54 of the plate member 50 is a long hole having an elongated planar shape in a direction perpendicular to the web 28 of the column 12. Thereby, the plate member 50 can be moved in a direction perpendicular to the web 28 of the support column 12 with respect to the plate-like body 14, and the position of the plate member 50 can be adjusted with respect to the plate-like body 14.

  In the illustrated state in which the plate member 50 is fixed to the plate-like body 14, the plate member 50 is a main body 58 that faces the back plate 38 of the plate-like body 14, and an extending portion 60 that extends from the main body. An extension 60 extending from the side 32 of the body 14 toward the web 28 of the post 12. The main body 58 of the plate member 50 is in contact with the back plate 38 of the plate member 14, and the extending portion 60 of the plate member 50 protrudes from the back plate 38 of the plate member 14 toward the web 28 of the support column 12. The bolt hole 54 of the plate member 50 is provided in the main body 58, and the plate member 50 is fixed to the plate-like body 14 by the main body 58. The plate member 50 may further include an extension 62 that extends from the extension 60 and contacts one flange 24 of the column 12.

  The fixing means 52 is disposed between the plate member 50 and the other flange 26 of the support column 12, and the other flange 26 is used as a reaction force support, and the side portion 32 of the plate-like body 14 is provided via the plate member 50 as one flange. It consists of pressing means that presses against 24. The pressing means includes a plurality of bolts 64 (see FIG. 1) arranged at intervals in the vertical direction, and nuts 66 screwed to the bolts. Each bolt 64 extends from the plate member 50 toward the other flange 26 of the column 12. The nut 66 is fixed to the main body 58 or the extended portion 60 of the plate member 50 by welding, and the head portion 68 of each bolt 64 is directed to the other flange 26 of the column 12.

  The length by which the bolt 64 protrudes from the nut 66 can be changed by rotating the bolt 64. The bolt 64 protrudes until the head 68 comes into contact with the other flange 26 of the support column 12, so that the side portion 32 of the plate structure 14 is supported through the plate member 50 fixed to the plate structure 14. 12 can be pressed against one of the flanges 24. Thereby, the plate-like body 14 can be fixed to the column 12. At this time, the bolt 64 receives a reaction force from the other flange 26 of the column 12. Further, by loosening the bolt 64, the fixation of the plate-like body 14 to the column 12 can be released. A nut 70 for preventing the bolt from loosening can be screwed onto the bolt 64 adjacent to the nut 66.

  The fixing means 52 for fixing the plate-like body 14 to the column 12 is composed of the pressing means. For example, a bolt hole in which a bolt for fixing the plate-like body 14 to the column 12 is arranged in the column 12. The plate-like body 14 can be fixed to the column 12 without the need to form it and without causing the fixing means 52 to protrude outside the space defined by the two flanges 24 and 26 of the column 12. For this reason, the time and labor for forming a bolt hole in the support | pillar 12 are not required. Further, the plate-like body 14 can be fixed to the support column 12 more economically. Furthermore, since the fixing means 52 is not projected out of the space between both the flanges 24 and 26 of the support column 12, there is little risk that a passerby will catch clothes, and the appearance is also preferable.

  The width dimension of the plate-like body 14 can be substantially changed before and after the plate member 50 is fixed to the plate-like body 14. That is, the plate-like body 14 before fixing the plate member 50 to the plate-like body 14 has a small width dimension, and the plate-like body 14 after fixation has a large width dimension.

  When the plate-like body 14 to which the plate member 50 is not fixed is disposed between the two pillars 10, 12, first, one side portion 30 of the plate-like body 14 is placed on the two flanges 18, 20 of the one pillar 10. After being guided in between and further pushed toward the web 22, the other side 32 can now be guided between the flanges 24, 26 of the other strut 12. For this reason, it is possible to arrange the plate-like body 14 between the both struts 10 and 12 without depending on the conventional suspension work of the plate-like body from the upper position of the both struts.

  In addition, after the plate-like body 14 is disposed between both the struts 10, 12, the plate member 50 is fixed to the plate-like body to substantially increase the width dimension of the plate-like body 14. , 12 can increase the overlap length, that is, the wrap length, of the side portions 30 and 32 of the plate-like body 14 with respect to the two flanges. Thereby, even when the plate-like body 14 receives an external force due to an earthquake, a wind or the like and moves relative to both flanges of the respective pillars 10 and 12 in the width direction of the plate-like body 14, It is possible to reliably prevent the plate-like body 14 from coming out from between both flanges.

  Further, since the plate member 50 is in contact with the one flange 24 of the column 12 at the extension 62, the plate member 50 fixed to the plate-like body 14 is pressed against the one flange 24 of the column 12 by the fixing means 52. be able to. Thereby, it is possible to more reliably prevent the plate-like body 14 from coming out from between both flanges of the respective columns 10 and 12.

  In addition, since the position of the plate member 50 can be adjusted with respect to the plate-like body 14, the substantial width dimension of the plate-like body 14 can be adjusted according to the distance between both the columns 10 and 12.

  Each support | pillar 10 and 12 may replace with the example of illustration consisting of H-section steel, and may consist of channel steel, a steel plate, etc. FIG.

  The plate-like body 14 may be formed by dividing the upper and lower parts into two or more.

  The plate member 50 replaces the illustrated example having the main body 58 fixed to the back plate 38 of the plate-like body 14 and the extending portion 60 extending from the main body toward the web 28 of the support column 12. It may have another shape such as a main body fixed to the side plate 40 and an extending portion extending from the main body toward the web 28 of the support column 12.

  The fixing means 52 is replaced with the bolt which penetrates the extending part 60 of the plate member 50 and the one flange 24 of the column 12 and the screw between them and the outside between the flanges 24 and 26 instead of the illustrated example comprising the pressing means. The nut may be in contact with one flange 24.

  Further, in the illustrated example, the plate-like body 14 is fixed to the support columns 10 and 12 by the fixing means 52 via the one plate member 50 at each side portion thereof. 14 can be fixed to each of the columns 10 and 12 by the fixing means 52 via two or more plate members arranged at intervals in the vertical direction at each side portion. In this case, the fixing means 52 can be composed of the bolts arranged on the plate members and the nuts screwed to the bolts and fixed to the plate members.
