Description

  The present invention relates to an attachment device for attaching a soundproof panel, which is installed in a construction site to prevent leakage of construction noise to the outside, on the outer periphery of a temporary scaffold.

  In a temporary scaffold constructed at a construction site, a soundproof panel is provided to prevent work noise from leaking to the outside.

  FIG. 20 shows a state in which the soundproof panel 10 and the foot board 3 are disposed on the temporary scaffold 1. The soundproof panel 10 is a structure in which a plurality of pieces are continuously attached to the support column 2 by a clamp coupled to the support frame 2 made of a single pipe or the like, and the outside of the temporary scaffold is surrounded by the soundproof panel 10. It is.

  As shown in FIG. 21, the soundproof panel 10 is obtained by covering the periphery of a panel material 11 made of a sound absorbing material, a sound absorbing plate, a sound insulating plate or the like with a metal frame 12, and both end portions of upper and lower edge frames of the metal frame 12. Each is provided with a through hole 12a for inserting a pin.

  22 and 23 show a state in which the soundproof panel 10 is attached to the temporary scaffolding column 2 using the clamp 20. The clamp 20 includes a pipe clamp 24 having a known structure including a base member 21, a pressing member 22, and a tightening bolt nut 23, and a pair of L-shaped mounting pins 25 and 25 fixed to the base member 21 of the clamp 24. Each L-shaped mounting pin 25 is formed in an L shape with a horizontal portion 25a and a vertical portion 25b, and the base end portion of the horizontal portion 25a projects perpendicularly to the bottom surface of the base portion of the base member 21. It is installed. The soundproof panel 10 is attached to the temporary scaffolding strut 2 by inserting the vertical portion 25b from below into the through hole 12a of the metal frame 12 disposed in the peripheral portion of the soundproof panel 10.

Japanese Patent Laying-Open No. 2015-78569

  As shown in FIG. 24, the foot board 3 is a rectangular plate-like body, and locking portions 3a having arc-shaped concave portions for locking to the temporary scaffolding columns 2 are provided at both ends thereof. As for the length B in the longitudinal direction of the general-purpose product of the tread plate 3, one having an inch size and one having a metric size are in circulation. Specifically, as the approximate dimensions, those having a longitudinal length B of 1829 mm and 1800 mm coexist.

  As shown in FIG. 20, the footboard 3 is locked to the temporary scaffolding column 2a disposed in the horizontal direction, but is disposed in the horizontal direction with respect to the temporary scaffolding column 2 disposed in the vertical direction. As a result, the distance A between the temporary scaffolding struts 2 and 2 arranged in the vertical direction is also defined by the dimension B of the tread board 3. Then, the dimensions of the soundproof panel 10 are also defined by the dimensions of the tread plate 3, and for example, a length of 1829 mm and a length of 1800 mm must be aligned, resulting in a complicated and uneconomic situation. .

  Moreover, since the soundproof panels adjacent in the vertical direction and the soundproof panels adjacent in the horizontal direction are fixed with the same clamp as described above, for example, the soundproof panel 10 disposed in the lower stage in FIG. 20 is damaged. For example, when it is necessary to replace the soundproof panel 10, it is necessary to remove the soundproof panel 10 in the upper stage. In a construction site, it is possible that the soundproof panel is frequently damaged as a result of work, and removing and attaching a large number of soundproof panels each time significantly impairs work efficiency.

  The present invention aims to solve the above-mentioned problems. Specifically, the present invention can be applied to any footboard of inch size or metric size, and when the soundproof panel is damaged, it is damaged. An object of the present invention is to provide a soundproof panel mounting device that can be attached by removing only the soundproof panel.

  The configuration of the present invention that achieves the above object is as follows.

  (1) The invention according to claim 1 is a pair of a plate-like body, a step portion provided in a direction perpendicular to the plate-like body, and a tip extending in a direction perpendicular to the step portion and having a bent tip. A rail member provided with a locking portion and a hole provided in the direction perpendicular to the plate-like body, and both sides of the plate body are bent to further bend the edges and from the center positions on both sides of the plate body. A hole was formed in the plate body by shifting, and a locking member provided with a bolt in the hole and a clamp provided with a hole through which a tightening member was inserted in the side wall.

  (2) The invention described in claim 2 is the soundproof panel mounting device according to claim 1, further comprising a cylindrical body through which the fastening member is inserted.

  It will be outlined with reference to the drawings how the present invention configured as described above works to solve the problems. In addition, the soundproof panel attachment member concerning this invention is applied to the conventional temporary scaffold 1 assembled with the support | pillar 2 for temporary scaffolds as shown in FIG.

  FIG. 1 shows a state in which the rail member 10 is attached to the clamp 20. The rail member 10 is fixed to the clamp 20 fixed to the scaffolding column 2 using the tightening member 50.

  2 and 3 show a state in which the soundproof panel 30 is attached to the rail member 10 fixed to the scaffolding column 2 in this way. At this time, depending on whether the soundproof panel 30 is attached on the stepped portion 12 as shown in FIG. 3 or attached on the plate-like body 11 as shown in FIG. Therefore, it is possible to attach the same length of the soundproof panel 30 to any footboard of inch size or metric size.

  That is, if the soundproof panel 30 is mounted on the stepped portion 12 as shown in FIG. 5, the soundproof panel 30 can be mounted near the center position of the rail member 10 (indicated by the virtual line C2). When the flow is metric and short, for example, 1800 mm, the soundproof panel 30 can be attached between the adjacent rail members 10, 10, that is, between the adjacent scaffolding columns.

  On the other hand, if the soundproof panel 30 is attached on the plate-like body 11 as shown in FIG. 4, the soundproof panel 30 is attached farther than the case shown in FIG. 5 from the center position of the rail member 10 (indicated by the virtual line C1). As a result, when the flow of the tread is an inch and long, for example, 1829 mm, it is possible to attach the soundproof panel 30 between the adjacent rail members 10, that is, between the adjacent scaffolding columns. It becomes.

  In this way, according to the present invention, it is possible to deal with any footboard of inch size or metric size.

  6 and 7 show a state in which the soundproof panel 30 is attached to the rail member 10 using the locking member 40. FIG. The locking member 40 is locked to the locking portion 13 constituting the rail member 10, and the frame body 31 of the soundproof panel 30 is attached to the rail member 10 by the bolt 42 inserted into the hole portion of the locking member 40. The soundproof panel 30 is fixed by pressing.

  As described above, according to the present invention, the soundproof panels positioned on the top and bottom or the left and right are not fixed with the same clamp as in the conventional example. Therefore, as long as the locking member 40 is removed regardless of the mounting position, Only one sheet can be removed or attached.

  In the second aspect of the present invention, as shown in FIG. 1, the fastening member 22 constituting the clamp 20 is inserted into the cylindrical body 50. This is because the cylindrical member 50 is interposed to secure the distance between the clamp 20 and the rail member 10, thereby facilitating the attachment and removal of the locking member 40, and hence the soundproof panel 30. It is.
