Description

  The present invention relates to a panel fixture used when a panel such as a sound absorbing panel is attached to a support frame framed by pipes.

  In general, in building construction sites and road construction sites, in order to reduce noise, a support frame that is framed with pipes such as scaffolding frames is set up around the site, and a panel such as a sound absorbing panel is attached to the support frame to fence And measures to prevent noise surrounding the site with the fence.

  When a panel such as the above-described sound absorbing panel is attached to a support frame that is framed by a pipe, if it is configured to be screwed using bolts and nuts, it takes much time to install and remove the panel.

  In order to eliminate such inconveniences, in Patent Document 1, the installation pipe can be clamped by pressing the installation pipe, and the installation pipe can be released by operating the release lever. A panel fixture is proposed, and the panel fixture is used to attach and remove the panel.

  Here, in the panel fixture described in Patent Document 1, an arcuate pipe fitting recess is provided on the front side of the bracket attached to the panel, and is supported by the bracket between the holding position and the release position. A swingable jaw member is provided with a concave holding surface, a first leg that closes the recess in the holding position, and a second leg that faces the tip in the recess in the release position, and biases the jaw member Selectively biased toward the holding position or the release position by means, and the jaw member is released by swinging the stopper supported by the bracket and swingable between the locked position and the unlocked position to the locked position. It locks in position.

  In the above panel fixture, when the stopper is in the locked position and the jaw member is in the holding position, when the fitting pipe is fitted into the recessed portion of the bracket and the bracket is pushed in, the jaw member swings to the holding position. Thus, the first leg closes the recess of the bracket, and the pipe is sandwiched between the recess of the bracket and the first leg, and the panel can be easily attached to the pipe.

  By the way, in the said conventional panel fixture, since the direction of the recessed part for pipe fitting provided in the bracket is determined by attaching the bracket of a panel fixture to a panel, a horizontal installation pipe and a vertical orientation are determined. There is a disadvantage that the panel can be attached only to one of the installation pipes.

  An object of the present invention is to provide a panel fixture that allows a panel to be easily attached to an erected pipe in an arbitrary direction.

  In order to solve the above-mentioned problems, the present invention comprises a base member attached to one side of a panel and a pipe clamp that is superimposed on the surface of the base member and is relatively rotatably connected. A clamp is rotatably connected to the base member, and has a bracket having an arcuate pipe fitting recess in the front side portion that can receive a construction pipe for supporting a panel, a front arm portion, and a rear arm portion. An arc-shaped pipe receiving recess is provided between the pair of front and rear arm portions, and an arcuate pipe receiving recess is provided to allow the installation pipe to be received, and the front arm portion closes the opening of the pipe fitting recess of the bracket, The holding position for holding the installed pipe at the periphery, the front arm portion opens the opening of the pipe fitting recess, and the tip of the rear arm portion is the pipe fitting recess A clamp member that is swingably connected to a bracket so as to be able to swing between a release position facing inward, and a dead point that causes switching of the biasing direction during the swinging of the clamp member. A configuration including spring biasing means for selectively switching and biasing the member toward the release position or the clamping position is adopted.

  In the panel fixture which consists of said structure, a base member is attached and used for the single side | surface of a panel. When attaching the panel to the support frame framed by the pipe, the clamp member is set to the release position, and the bracket is fitted to the outer periphery of the installation pipe so that the installation pipe is fitted into the pipe fitting recess of the bracket. The bracket is pushed toward the installation pipe from a state in which the front end of the rear arm of the member is in contact with the outer periphery of the installation pipe. As a result, the tip of the rear arm of the clamp member is pushed by the installation pipe, the clamp member swings toward the clamping position, and the front arm is installed by the inner periphery of the pipe fitting recess of the bracket. The pipe is clamped and the pipe clamp is attached.

  Here, since the pipe clamp which clamps a construction pipe is rotatably connected with respect to the base member fixed to a panel, the bracket which has a pipe fitting recessed part rotates the bracket with respect to a base member. The direction of the pipe fitting recess can be adjusted.

  Therefore, by adjusting the orientation of the pipe fitting recess according to the orientation of the installation pipe, the installation pipe can be securely held between the bracket and the clamp member, and the panel can be securely attached to the installation pipe of any orientation. Can be installed.

  In addition, the installation pipe can be clamped by the pipe clamp by a simple operation of pushing the bracket toward the installation pipe from the state in which the installation pipe is fitted in the pipe fitting recess of the bracket. it can.

  In the panel fixture according to the present invention, as a spring biasing means, a spring biasing means with a lock function having a lock function for preventing the clamp member from swinging toward the release position at the clamping position of the clamp member. It is possible to oscillate around the oscillation axis of the clamp member or its vicinity, and unlock the spring urging means with the lock function when the oscillation end is oscillated by pushing down. By providing an operation lever that swings the clamp member to the release position against the elasticity of the spring biasing means, the lock function is activated in a state where the pipe clamp holds the installation pipe, and the clamp member is moved to the release position. Therefore, it is possible to obtain a very safe panel mounting state.

  Then, when the pipe clamp clamps the erected pipe, if the swing side end of the operating lever is pushed in, the lock of the spring biasing means with the lock function is released, and the clamp member resists the elasticity of the spring biasing means. Then, it swings toward the release position to release the holding pipe. Since the tip of the rear arm presses the erected pipe in the middle of the release, the pipe clamp can be easily removed from the erected pipe.

  Here, as a spring urging means with a lock function, a guide hole formed in the bracket, a linear long hole formed in the clamp member and extending long toward the swinging central axis of the clamp member, and the linear shape A guide pin that is inserted into the communicating portion of the long hole and the guide hole and is pushed down by the downward swing of the operation lever, and a notch that engages with the guide pin are provided at the front end, and the bracket at the rear end. A pressing element formed with a long hole guided by a fixing pin provided at the lower part and an elastic member that urges the pressing element toward the guide pin, and the guide hole is the center of oscillation of the clamp member. It is possible to employ a configuration in which a notch portion into which a guide pin can be fitted is provided at one end portion of the upper side of the arc-shaped long hole centered on the shaft.

  In the spring urging means with a lock function having the above-described configuration, when the notch is an arc extending along the upper side of the arc-shaped elongated hole and the length between both ends is equal to or larger than the outer diameter of the guide pin, the clamping position Since the clamp member biased by the guide pin can be swung within a range in which the guide pin contacts both ends of the arc-shaped notch, the pipe clamp can be attached to several types of pipes having different outer diameters. be able to.

  In the panel fixture according to the present invention, the base member is framed by a pipe by making the position of the base member adjustable along a guide groove provided in the panel and fixing the base member at an adjusted position by a fastening means. Panels can be attached to various support frames.

  In the panel fixture according to the present invention, as described above, the pipe clamp for clamping and releasing the installation pipe is rotatably connected to the base member fixed to the panel, so that the installation pipe is oriented vertically. Regardless of orientation, sideways, or diagonal orientation, the pipe can be rotated and the orientation of the pipe fitting recess formed on the bracket can be adjusted so that the installation pipe can be securely clamped. The panel can be securely attached to the installation pipe.

  In addition, the installation pipe can be clamped by the pipe clamp by a simple operation of pushing the bracket into the installation pipe from the state in which the installation pipe is fitted in the pipe fitting recess of the bracket forming the pipe clamp. Can be installed easily.
