Description

  The present invention uses fixed structures such as guardrails and gates installed on the roadside, and lights that illuminate the site in signs and signs with signs, signs, etc., especially at night road construction, The present invention relates to a column support device for easy fixing and installation.

  Conventionally, signs and signs with pillars are fixed to guardrails or utility poles by fastening the pillars, but it is not possible to fix lights for illuminating the site at night road construction etc. I have not been told. A normally used lighting device is an integrated generator, lamp, and support. However, this apparatus is very heavy because it has a built-in power generation engine and the struts supporting the lamps are strong, and has a certain area for installation and is expensive. Therefore, there is a drawback that a sufficient number cannot be carried to the construction site.

  Therefore, a method of reducing the weight of the lamp / post and separating the power source and supporting the post with a tripod has begun to be provided. According to this method, it is easy to carry in the lighting device to the construction site. However, since the tripod is expanded on site, there is a drawback that the area required for installation becomes larger than that of the above-mentioned projector. In addition, there is a disadvantage that the number of weights for stabilizing the tripod must be prepared for the number of tripods.

  As a method of installing a road sign or a signboard for a construction site using a guardrail conventionally, for example, Japanese Utility Model Laid-Open No. 3-76018 (Patent Document 1), Registered Utility Model No. 3065559 (Patent) Document 2). In the technique disclosed in Patent Document 1, the upper and lower sides of the guard rail are sandwiched between holding brackets, and the support pillars extending from the receiving frame body that fixes the display panel are fixed. In this method, a sign or the like can be fixed to an existing guard rail, but the fixing method is very complicated.

  That is, after the upper holding bracket extending from the support is locked to the upper end of the guard rail, the lower holding bracket is locked to the lower end of the guard rail. It is necessary to move the holding bracket to the lower end of the guard rail while rotating the bolt, and there is a problem that it is extremely difficult to operate the bolt in the nearby terrain or dark places such as at night. Note that this document does not even disclose the concept of fixing the light projection lamp to the guardrail for the purpose of fixing the construction site display board.

  The technique disclosed in Patent Document 2 discloses a holder for fixing a display board or a sign board for ensuring safety of road traffic to a guard rail, and two clamps are attached to a main body to which a sign is attached. After the legs are attached, the guard rail is sandwiched between the sandwiched legs, and the lower ends of both sandwiched legs are tightened with bolts to reduce the gap between the sandwiched legs, and are fixed to the guard rail.

Compared to the previous device, the method of attaching to the guardrail is slightly simpler, but after pinching the guardrail, it is necessary to fix the clamp legs with bolts below the guardrail. Has the disadvantage that its operation is difficult. Further, it is the same as the above-described device that only aims to fix a sign or the like. In this way, there is currently no way to fix a light for illuminating the site during night road construction or the like by using an existing guardrail or gate on the roadside.
Japanese Utility Model Publication No. 3-76018 Registered Utility Model No. 3065590

  The present invention uses fixed structures such as guardrails and gates installed on the roadside, and lights that illuminate the site in signs and signs with signs, signs, etc., especially at night road construction, It is intended to provide a column support device for easy and reliable installation.

  In order to solve the above-mentioned problems, the present invention adopts a first holding plate having a fixing means for fixing the support column and a second holding device having a clamping means having a clamping plate at the tip. A plate, an upper mounting plate that connects the upper ends of the two holding plates, and a detachable connecting member that connects the lower ends of the first holding plate and the second holding plate. And an existing structure is located in a downward U-shaped space created by the upper mounting plate, the first holding plate and the second holding plate are connected by a connecting member, and the structure is attached by tightening means. It is characterized in that it is clamped and fixed with the first clamping plate.

  The anti-tilt wings are extended to both ends in the short direction of the upper mounting plate, and the shape of the fastening plate is a disc shape or a long plate shape. .

  The structure to be fixed is a guardrail already installed on the roadside.

  The present invention fixes a device main body so as to sandwich an existing structure such as a guard rail installed on a roadside or a gate, and signs, signboards, etc., particularly night lighting through a column to the device main body. Therefore, it is not necessary to install a tripod or a dedicated pedestal on the ground, and it is possible to reliably install whatever the ground of the installation location is.

  Moreover, since the column support device is fixed not only by the guardrail but also by sandwiching a structure such as a gate between the holding plates, it can be fixed at any place. In addition, the support | pillar fixed to a support | pillar support apparatus is not restricted to the above-mentioned thing, If it is provided with a support | pillar, it can fix to a desired location easily and reliably regardless of the kind.

  A preferred embodiment of the present invention will be described in detail below with reference to the drawings. In addition, the lamp | ramp and support | pillar which are especially used for night illumination as an example are demonstrated as an example. FIG. 1 is a perspective view of a column support device of the present invention. (1) is a main body of the device, and a first holding plate (2) and a hinge (3) on the first holding plate (2). The upper mounting plate 4 is connected, and the second holding plate 5 is connected to one end of the upper mounting plate 4 at a right angle. A fixed cylinder (6) for inserting and fixing a lamp post, which will be described later, is attached to the outer surface of the first holding plate (2), and the inserted support post is fixed to the fixed cylinder (6). The fixing screw (7) is screwed. A hook for connecting the chain (12) is attached to the lower end of the first holding plate (2), and a chain (which can be connected to the hook) is attached to the lower end of the second holding plate (5). 12) is installed.

  Anti-tilt wings (8) are extended on both sides of the upper fixing plate (4) in the short direction. This is in contact with the upper end of the guard rail in the longitudinal direction of the guard rail, thereby preventing the tilt when the support device main body (1) receives a tilting force for some reason. A bolt (9) is screwed in the middle of the second holding plate (5), a handle (9a) is attached to the outer end, and a clamping plate ( 10) is attached and constitutes a tightening means. A protective member (11) is attached to the guardrail contact surface of the first holding plate (2), the upper mounting plate (4), the anti-tilt blade (8), and the clamping plate (10). Prevents guardrail scratches. The protective member (11) is preferably, for example, MC nylon, but is not particularly limited thereto.

  Next, the fixing method to a guardrail is demonstrated. As shown in FIG. 2, first, the chain (12) connecting the lower ends of the first holding plate (2) and the second holding plate (5) is removed to make it open and the second holding plate ( 5) The fastening bolt (9) screwed into 5) is moved outward, that is, toward the handle (9a). Next, the protective member (11) of the first holding plate (2) is brought into contact with the surface side of the guard rail, and the upper mounting plate (4) is attached to the upper end of the guard rail. Next, the second holding plate (5) is rotated toward the guard rail with the hinge (3) as a base point, and the first holding plate (2), the second holding plate (5), and the upper mounting plate (4) ) After the guardrail is positioned in the downwardly U-shaped space created by), the first holding plate (2) and the second holding plate (5) are connected by the chain (12) to surround the guardrail. And

  Next, the handle (9a) is rotated to screw the tightening bolt (9) toward the first holding plate (2), and the tightening plate (10) is advanced toward the guard rail. The guardrail (13) has a generally arcuate shape as shown in the figure, and has a convex portion (13a) at the center of the back surface. The clamping bolt (9) is screwed into a corresponding position of the second holding plate (5) when the device (1) is mounted on the guard rail.

  Further, by rotating the handle (9a), the guard rail is pressed and held between the first holding plate (2) and the fastening plate (10). At this time, the first holding plate (2) and the second holding plate (5) try to widen the distance between them, but since both the holding plates are connected by the chain (12) as described above, The gap between the two clamping plates does not spread, and the pressing force of the clamping bolt (9) is applied to the first clamping plate (2) via the projection (13a) and the front flat portion (13b) of the guard rail. Thereby, a support apparatus main body (1) can be firmly fixed to a guardrail. Further, since the anti-tilt blade (8) extending from the upper mounting plate (4) is in contact with the longitudinal direction of the guard rail at the top of the guard rail (13), when any external factor acts on the support device body (1). Since the anti-tilt wing (8) acts to depress the guardrail, it is possible to prevent the inclination of the apparatus body as a result.

  FIG. 3 shows a state in which the support device main body (1) is fixed to the guard rail (13) by the above-described method, and the lamp (15) and the column (14) are further attached. The support post (14) is inserted into the fixed cylinder (6) of the first holding plate (2) to a desired position, the fixing screw (7) is tightened, and the support post (14) is fixed to the support device body (1). Needless to say, the column that can be fixed to the fixed cylinder (6) is not limited to the column for lamp.

  Since the power supply for the lamp is not provided in the support device of the present invention, a generator (23) as shown in FIG. 6, for example, is arranged near the guard rail and connected by a cable (22). A commercial power source can be used without using a generator. In this way, since it is not necessary to install a device such as a generator directly under the lamp, the lamp can be lit even when construction is performed directly under or near the lamp.

  FIG. 4 shows another embodiment. The basic structure is the same as that of the first embodiment, but there is a difference in the shape of the fastening plate. In the present embodiment, the fastening plate (20) has a long plate shape as shown in the figure. As a result, it is possible to hold existing structures such as guardrails and gates in the entire gap between the first holding plate (2) and the fastening plate (20). For example, the support device main body (1) can be fixed to a guard pipe (21) composed of two pipes as shown in FIGS.

  It is preferable to use a universal joint for the connecting portion (9b) between the fastening bolt (9) and the fastening plate (20). This makes it possible to provide an angle between the first holding plate (2) and the clamping plate (20). Even if the guard pipe (21) is made of pipes with different upper and lower diameters as shown in the figure, The attached plate (20) comes into contact with the upper and lower pipes at an angle with respect to the bolt (9), and the pressing force of the fastening bolt is applied, so that the support device main body (1) can be securely fixed. .

  As described above, the column support device of the present invention can be easily and securely fixed by simply tightening the fastening bolt after holding the existing structure. In the description, an existing guard rail on the roadside is taken as an example, but it is also possible to use a gate or a wall, and the fixing procedure in this case is as described above.
