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

 INDUSTRIAL APPLICABILITY The present invention is used for connecting adjacent louvers, which is used when attaching a cosmetic louver to a portion where the concrete surface is exposed, such as the underside of an elevated bridge girder or the ceiling of a concrete structure. The present invention relates to a connection device.

[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. When attaching the above louvers, it is often the case that a plurality of louvers are attached in an elongated state by sequentially connecting them in the axial direction. Conventionally, as a connection method, a suitable louver is provided between the ends of the two louvers. A method of bridging a relay member and fixing the relay member and each louver with a screw is generally used. However, in the method of fixing the relay member and each louver with screws, it is necessary to form a plurality of screw holes in the relay member and the louver, and to screw the screws at the positions of the respective screw holes. However, since the work is complicated and requires a lot of labor and time, and the work is performed in a high place or a place where the scaffolding is poor, it is extremely dangerous. Also, it is troublesome to finely adjust the connection length of the louver, and it is necessary to re-open the screw hole.

 A main object of the present invention is to provide a louver connecting device that can easily and reliably connect the louvers to each other without screwing the cosmetic louver and the relay member together. Another object of the present invention is to provide a louver connection device in which the connection length can be easily adjusted.

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the connecting device of the present invention comprises a relay member that is fitted to the opposite ends of two louvers across both louvers, and the relay member is movable in the axial direction of the louvers. In addition, it is characterized in that the intermediate portion located between the louvers is provided with a locking means for locking the louvers and restricting the movement in the axial direction. According to a preferred specific configuration of the present invention, the louver and the relay member have groove-shaped cross-sectional shapes that are substantially similar to each other, and the relay member fits inside the louver and the relay member The locking means for locking the end edge of the louver is formed on at least one side wall of the. In the present invention, the locking means is a protrusion integrally formed by bulging or cutting up a part of the wall of the relay member, or a screw such as a screw separately attached to the wall of the relay member. It is preferable that the protrusions or locking pieces are configured to be locked to the edge of the louver. In the connecting device having the above configuration, both louvers are connected by fitting one half of the relay member to one cosmetic louver and fitting the other half of the relay member to the other cosmetic louver. . In this case, the two louvers and the relay member are not fixed to each other with screws, but since each louver is fixed to the louver support fittings attached to the structure with appropriate fixing fittings, they are axially fixed. Does not move carelessly, and even if the relay material tries to move to the left or right louver side, the locking means locks on the louver on the moving direction side and further movement is restricted. . Therefore, the fitting state between the relay member and both louvers is reliably maintained, and the connection between both louvers is not released. Further, when mounting the louver, one half of the relay member is fitted to the end of one louver previously fixed at a predetermined position, and the other louver is fitted to the other half of the relay member. Even if the work of fixing them together is performed, unless the distance between both louvers is increased too much, the movement of the relay member is restricted by the locking means, and both halves of them are always fitted to both louvers. Because it leans, the work can be carried out easily. Moreover, since it is not necessary to screw each louver and the relay member to each other, not only can the work be carried out quickly, but the adjustment of the connection length of both louvers can be done by simply moving the louver along the relay member. The work is simple because all that is required is to slide them to change their mating length.

[Embodiment of device]

 Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. FIGS. 1 and 2 show a case where a cosmetic louver connected by a connecting device of the present invention is attached to a structure. Reference numeral 10 is a louver support member, 11 is a makeup louver fixed to the support member 10, 12 is a fixed metal fitting for fixing the support member 10 and the louver 11, and 13 is an axial direction between the louvers 11 and 11. The connection device for connecting 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. Further, the louver 11 has a groove-shaped cross-sectional shape, and has an attachment groove 15 extending in the axial direction on the upper surface thereof, and the row of the louvers 11 connected by the connecting device 13 is the support member 10. A plurality of rows are attached to the lower surface of the substrate at a required interval in a direction orthogonal to the supporting member 10. As can be seen from FIG. 3, the connecting device 13 is composed of a relay member 14 that is fitted to the opposite ends of the two louvers 11, 11 while straddling the louvers 11, 11. Since the relay member 14 has a groove-shaped cross-sectional shape substantially similar to that of the louver 11, it is formed to be slightly smaller than the louver 11 and is moved to the end portion of the louver 11 to move in the axial direction. The louver 11 is configured so that it can be fitted into the louver 11 while suppressing rattling as much as possible. At the intermediate portion in the axial direction of the relay member 14, at a portion located between the louvers 11 and 11, locking means 16 for locking the louvers 11 and 11 to restrict relative movement in the axial direction. Is provided. The locking means 16 may have any structure, but in the example shown in FIGS. 1 to 3, the locking means 16 is composed of a locking piece 16a separately fixed to the side wall 14a of the relay member 14. A screw is shown as an example of the stop piece 16a. However, the locking piece 16a is not limited to such a screw. Further, as shown in the right half of FIG. 4, a part of the side wall 14a of the relay member 14 is deformed to bulge in a direction to be locked to the edge of the louver 11, and a left half of FIG. As shown in the section, the locking means 16 can be configured by a protrusion integrally formed on the relay member 14, such as a protrusion 16c formed by cutting and raising a part of the side wall 14a. The position at which the locking means 16 is formed may be the side wall 14a, the bottom wall 14b, or the upper wall 14c as long as it is at an intermediate position in the axial direction of the relay member 14. Can be provided at a plurality of positions. Further, when it is provided on the side wall 14a as shown in the figure, it can be provided on one or both side walls. Furthermore, the locking means 16 can be provided separately for each of the two louvers 11, 11. The fixing metal fitting 12 may have any structure as long as it can fix the louver 11 to the supporting member 10, and therefore, details thereof will not be mentioned here. In the connecting device having the above structure, one half of the relay member 14 is fitted to one of the cosmetic louvers 11, and the other half of the relay member 14 is fitted to the other cosmetic louver 11, thereby The louvers 11 and 11 are connected, and the louvers 11 and 11 are fixed to the support member 10 by fixing fittings 12, respectively. In this case, the two louvers 11 and 11 and the relay member 14 are not fixed to each other with screws, but since each louver 11 is fixed to the support member 10 by the fixing bracket 12, they are not fixed in the axial direction. It does not move easily and therefore these louvers 11, 11 do not detach from the relay member 14 and disconnect. Further, even if the relay member 14 tries to move to the left or right, the locking means 16 locks on the louver 11 in the moving direction and further movement is restricted, so that the relay member 14 and both louvers 11 are prevented. , 11 is reliably maintained. Further, when mounting the louvers 11 and 11, the other half of the relay member 14 is fitted with one half of the relay member 14 fitted to the end of one of the louvers 11 which is previously fixed at a predetermined position. Even when the other louver 11 is fitted and fixed to the louver 11, the movement of the relay member 14 is restricted by the locking means 16 unless the space between the both louvers is excessively widened, and both half portions thereof are restricted. Since it is always kept fitted to both louvers 11 and 11, the installation work is easy, and the work can be safely carried out even in high places or places with poor scaffolding. Moreover, since it is not necessary to screw each louver 11, 11 and the relay member 14 to each other, not only can the work be carried out quickly, but the adjustment of the connection length of both louvers 11, 11 is simply done by them. Since the louver 11 can be slid along the relay member 14 to change the fitting length, the work is simple. Although the relay member 14 is fitted into the louvers 11 and 11 in the above-described embodiment, the louvers 11 and 11 may be fitted into the relay member 14 on the contrary. Further, the shapes of the louver 11 and the relay member 14 are not limited to the groove shape in cross section, and may be any other shapes that fit with each other.

[Effect of device]

 As described above, according to the present invention, the relay member is formed by an extremely simple structure in which the locking means for locking these louvers is formed at the intermediate position of the relay members fitted to the two cosmetic louvers. The two louvers can be easily and surely connected without screwing the louver for makeup and the louver for makeup. Further, since the two louvers and the relay member are not screwed, the connection length of both louvers can be easily adjusted by moving them relatively by the required length.
