Description

[Detailed description of the device] [Technical field to which the device belongs]

 The present invention relates to a mounting device for mounting a cosmetic louver on a portion of an elevated road where the concrete surface is exposed, such as the lower surface of a bridge girder or the ceiling of a concrete structure.

[Prior art]

 Conventionally, cosmetic parts such as the underside of bridge girders of elevated roads and the exposed concrete surfaces such as the ceiling of concrete structures have been improved by installing a cosmetic louver to cover them. There is. The conventional attachment of a cosmetic louver has been performed by the method shown in FIG. That is, the louver 2 is fixed to the louver support member 1 fixed to the structure with bolts and nuts. At this time, the rim 3a provided on the upper surface of the louver 2 in the axial direction has a narrow mounting groove 3a. A required number of bolts 4 are inserted from one end of the louver 2 so that the bolt heads 4a project from the mounting groove 3 with the bolt head 4a engaged in the mounting groove 3, and each bolt 4 is supported. The bolt 5 was inserted into the bolt insertion hole 1a and tightened with the nut 5. However, in the above-described conventional fixing method, since a large number of bolts 4 have to be sequentially inserted from the end of the louver into the mounting groove 3 formed in the long louver 2, the inserting work is not only troublesome. Instead, if the intermediate bolt 4 is damaged during the attachment to the support member 1 or the correspondence between the bolt 4 and the bolt insertion hole 1a is incorrect, only the intermediate bolt is replaced or increased or decreased. It was impossible, and I had to remove the louver 2 and start over. Moreover, since the bolts 4 inserted into the mounting grooves 3 freely move along the mounting grooves 3, it is very troublesome to associate a large number of bolts with the respective bolt insertion holes of the supporting member, and the workability of mounting is reduced. It had the drawback of being bad.

[Problems to be solved by the device]

 An object of the present invention is to easily set a fixing metal fitting for fixing a support member and a cosmetic louver from the outside through an attachment groove at an arbitrary position of the louver and easily attach the fixing member at an arbitrary position. An object of the present invention is to provide a mounting device which is excellent in workability of mounting the cosmetic louver. Another object of the present invention is to provide a cosmetic louver mounting device in which deformation of the louver does not easily occur during tightening.

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the attachment device of the present invention is to fix the louver support member fixed to the structure, the cosmetic louver attached to the support member, and the support member and the louver to each other. The louver has a mounting groove extending in the axial direction and locking edges bent toward the inner side of the louver at both groove edges of the mounting groove. Is a substantially U-shaped locking member that is disposed inside the louver such that the standing wall portions at both ends contact the louver while straddling the above-mentioned mounting groove and locking edge, and the locking member attached to the locking member. And a bolt protruding from the mounting groove to the outside of the louver, and a spacer fitted to the bolt and located between both locking edges for preventing deformation of the locking edge, and Remove the locking member, bolt and spacer. A temporary fastening means for temporarily fastening to the bar and a fastening nut screwed to the bolt for fastening and fixing the support member and the louver between the support member and the louver are provided. However, the member width of the locking member in the direction orthogonal to the direction connecting the compatible wall portions is narrower than the groove width of the mounting groove. According to a specific configuration aspect of the present invention, the temporary fixing means has a diameter larger than the groove width of the mounting groove, which is fitted to the bolt and can come into contact with the louver from outside the mounting groove. The plate includes a plate and a temporary fixing nut screwed to the bolt for tightening the temporary fixing plate. In this case, it is preferable that the temporary fixing plate has a disk shape and the diameter thereof is at least equal to the distance between the compatible wall portions of the locking member. In the present invention, it is desirable that the spacer has a cylindrical shape, and the outer diameter of the cylinder is slightly smaller than the groove width of the mounting groove. Further, in the present invention, the bolt insertion hole provided in the support member is preferable. However, in order to allow the temporary fixing nut to escape, it is desirable that the diameter is larger than that of the temporary fixing nut. In the mounting device having the above-mentioned configuration, the fixing member with the temporary fixing means sufficiently loosened is held with the locking member in a state in which the line connecting the compatible wall portions of the locking member is parallel to the mounting groove. After being inserted into the louver through the mounting groove, the locking member is rotated 90 degrees in the direction straddling the mounting groove to tighten the temporary fixing means to the required strength, so that the louver can be attached to the outside through the mounting groove at any position. Can be easily set and can be easily attached to any position. Further, even when the bolt and the locking member rotate and the compatible wall portion of the locking member strongly abuts the locking edge when the louver is fixed to the support member by tightening the fixing nut, Since a spacer is provided between the locking edges to support both locking edges, the locking edges do not deform in the direction in which the mounting groove narrows.

[Embodiment of device]

 Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. In FIGS. 1 to 3, 10 is a louver support member, 11 is a cosmetic louver fixed to the support member 10, and 12 is a makeup louver. A fixing fitting for fixing the support member 10 and the louver 11 is shown. The support member 10 is made of a material having a U-shaped cross section, and the exposed concrete surface of the underside of the bridge girder of an elevated road or the ceiling of a concrete structure is covered with the louver 11. It is attached by a suitable means at a position suitable for. The cross-sectional shape of the support member 10 is not limited to this, and it goes without saying that it may have another cross-sectional shape to which the louver 11 can be attached. The louver 11 has a groove-shaped cross section, has an attachment groove 15 extending in the axial direction on its upper surface, and is bent toward the inside of the louver 11 at both groove edges of the attachment groove 15. A plurality of louvers 11 having locking edges 15a, 15a are attached to the lower surface of the support member 10 in a direction orthogonal to the support member 10 with a required space. Further, the fixing fitting 12 has a locking member 17 that contacts and locks the louver 11 inside the louver 11. The locking member 17 is a substantially U-shaped member having a pair of standing wall portions 17a, 17a rising upwards at both ends, and is provided inside the louver 11 with the mounting groove 15 and the locking member. The upper ends of the compatible wall portions 17a, 17a are arranged so as to abut the lower surface of the upper wall of the louver 11 while straddling the edges 15a, 15a. Further, the locking member 17 is formed such that the member width A in the direction orthogonal to the direction connecting the compatible wall portions 17a, 17a is narrower than the groove width B of the mounting groove 15 (see FIG. 4). Thus, when the fixing metal fitting 12 is set on the louver 11, the locking member 17 is oriented in a direction different by 90 degrees from the case of FIG. 2, that is, the compatible wall portions 17a and 17a are connected as shown by the solid line in FIG. The locking member 17 can be inserted into and removed from the louver 11 at an arbitrary position of the attachment groove 15 by orienting the line in parallel with the attachment groove 15. A bolt 18 projecting from the mounting groove 15 toward the outside of the louver 11 is fixed at a substantially central position of the locking member 17 by means such as welding, and the bolt 18 has locking edges 15a, 15a. A spacer 19 for preventing deformation is fitted. The spacer 19 has a cylindrical shape, has an outer diameter slightly smaller than the groove width B of the mounting groove 15, and has a height substantially equal to the height of the standing wall portion 17a of the locking member 17, By being located between both the locking edges 15a, 15a, when the fixing nut 20 is screwed and tightened, the locking member 17 rotates and the compatible walls 17a, 17a become the locking edges 15a, 15a. Even when they come into strong contact, the locking edges 15a, 15a are prevented from being deformed in the direction in which they approach each other. The bolt 18 is also provided with a temporary fastening means 22 for temporarily fastening the fixing member 12 to the louver 11, and the support member 10 and the louver 11 between the locking member 17 and the fastening member 22. The fixing nut 20 and the washer 23 for fixing each other are attached. The temporary fixing means 22 is a disk-shaped temporary fixing plate 25 having a diameter larger than the groove width B of the mounting groove 15 so that the louver 11 can be contacted from outside the mounting groove 15, and the temporary fixing plate 22. It is composed of a temporary fixing nut 26 for tightening the rate 25 from the outside. By tightening the temporary fixing nut 26 with a required force, the fixing metal fitting 12 is fixed at an arbitrary position along the mounting groove 15. I'm supposed to get it. In this case, if the position of the fixing bracket 12 is fixed, the temporary fixing nut 26 may be tightened to some extent, but if the position of the fixing bracket 12 is not yet determined, the temporary fixing nut 26 By loosely tightening, the position of the fixing metal fitting 12 can be easily adjusted by moving the fixing metal fitting 12 along the mounting groove 15. The temporary fixing plate 25 and the temporary fixing nut 26 are preferably formed as thin as possible within a range in which required strength can be obtained. In fixing the louver 11 to the support member 10 in the embodiment having the above-described structure, the necessary number of fixing fittings 12 are set on the louver 11. In this case, the fixing metal fittings 12 with the temporary fixing nuts 26 loosened are sequentially mounted from the end of the louver 11 toward the direction in which the locking member 17 straddles the mounting groove 15 (direction in FIG. 2). Although it may be inserted into the louver 11, the fixing metal fitting 12 can be set on the louver 11 at an arbitrary position of the mounting groove 15 by mounting as shown in FIG. That is, as shown by the solid line in FIG. 4, the fixing metal fitting 12 in which the temporary fixing nut 26 is sufficiently loosened is placed in a direction in which the line connecting the upright wall portions 17a, 17a of the locking member 17 is parallel to the mounting groove 15. The locking member 17 is inserted into the louver 11 through the mounting groove 15 in the state where the locking member 17 is turned toward, and then the bolt 18 is rotated 90 degrees, so that the locking member 17 is moved as shown by a chain line in FIG. Face the mounting groove 15 and tighten the temporary fixing nut 26 to the required strength. As a result, the fixing member 12 is fixed to the louver 11 by the locking member 17 and the temporary fixing plate 25. In this case, it is desirable to remove the washer 23 and the fixing nut 20. When removing the fixing bracket 12 attached to the louver 11, by performing the reverse operation to the above-mentioned mounting, it can be easily removed at that position. Next, the louver 11 is brought into contact with the lower surface of the support member 10, and the bolts 18 of each fixing tool 12 are respectively inserted into the bolt insertion holes 28 of the support member 10, and the bolts 18 are inserted through the washers 23. The louver 11 is fixed to the support member 10 by screwing and tightening the fixing nut 20. At this time, in order to prevent the temporary fixing nut 26 from hitting the supporting member 10, the bolt inserting hole 28 of the supporting member 10 has a larger diameter than the temporary fixing nut 26, and the large diameter bolt inserting hole 28 Therefore, it is desirable to allow the temporary fixing nut 26 to escape. The temporary fixing nut 26 is formed to be thinner than the thickness of the supporting member 10 so that the temporary fixing nut 26 does not come into contact with the washer 23. Further, when the fixing nut 20 is tightened, even if the bolt 18 and the locking member 17 rotate and the compatible wall portions 17a, 17a of the locking member 17 strongly contact the locking edges 15a, 15a. Since there is a spacer 19 between the locking edges 15a, 15a to support both locking edges 15a, 15a, the locking edges 15a, 15a are deformed in the direction in which the mounting groove 15 narrows. There is no such thing. Further, it is desirable that the diameter of the temporary fixing plate 25 is at least the same as the distance between the compatible wall portions 17a, 17a of the locking member 17, so that the distance between the support member 10 and the louver 2 is reduced. Even if the temporary fixing plate 25 is interposed, the portion of the louver 2 corresponding to the temporary fixing plate 25 will not be dented by tightening.

[Effect of device]

 As described above, according to the present invention, the fixing bracket can be easily set from the outside through the mounting groove to an arbitrary position of the louver, and can be easily fixed to a desired position by the temporary fixing means. The workability of installing the louver is very good. Further, since the fixing metal fitting is provided with a spacer located between the locking edges of the louver to support the locking edges, the locking edges are abutted against each other when the fixing nut is tightened. It is possible to reliably prevent the deformation.
