It takes time and effort to attach the runner construction aid to the ceiling with screws. In addition, in the work of rotating the pressing plate to press against the runner, if the runner is to be temporarily fixed with the pressing plate, the load when rotating and pressing the pressing plate against the runner increases, making the work easier. undermined.

SUMMARY OF THE INVENTION The present invention has been made in view of the circumstances described above, and an object of the present invention is to facilitate the work of a worker who attaches a runner to a ceiling.

(1) The runner construction aid according to the present invention is attached to a rod-shaped construction member that is constructed on the floor and ceiling. The runner construction aid includes a temporary placement portion where the runner is temporarily placed, a main body attached to the installation member, and a support position rotatably held by the main body, with the leading end of the rotation facing the ceiling. a rotating element rotatable between a non-supporting position in which the tip of rotation faces away from the ceiling; and a slide member that is slidable between a retracted position on the rotation center side and a protruded position that protrudes outward from the retracted position; a force member;

A worker installs the installation members on the floor and the ceiling, temporarily places the runner on the temporary placement portion, and then inserts the cable wire through the through hole of the runner. After placing the runner at an appropriate installation position, the operator rotates the rotor from the non-supporting position to the supporting position. When the rotor is rotated, the tip of the slide member abuts against the runner and slides from the protruded position to the retracted position. The slide member in the retracted position presses the abutting runner against the ceiling due to the biasing force received from the biasing member. That is, the runner construction aid temporarily fixes the runner to the ceiling. A worker drives a screw into the runner temporarily fixed to the ceiling to attach the runner to the ceiling. Since the worker can temporarily fix the runner to the ceiling only by rotating the rotor, the worker can easily attach the runner to the ceiling.

(2) The rotating element may be provided at a position on the opposite side of the construction member with the main body interposed therebetween.

Since the rotator is provided on the opposite side of the construction member with the main body interposed therebetween, the construction member does not interfere with the rotation of the rotator by the operator.

(3) The rotating element may have a first supporting piece and a second supporting piece, which are provided at the tip of the rotation of the rotating element and are opposed to each other in the radial direction of rotation. . The first support piece and the second support piece each have an insertion hole through which a bolt is inserted. The bolt is fixed to the slide member. The bolt is fastened with a nut positioned between the first support piece and the second support piece. The biasing member is a coil spring through which the bolt is inserted, one end of which contacts the first support piece and the other end of which contacts the nut.

The contact of the nut with the second support piece restricts the slide member from sliding beyond the projecting position. Also, the bolt holds a biasing member that is inserted therethrough. That is, the bolt can restrict the slide member from sliding beyond the projecting position, and can hold the biasing member.

(4) The temporary placement portion may be provided on the rotating element, and may assume a posture capable of holding the runner when the rotating element is in the supporting position.

The temporary placement portion assumes a posture capable of holding the runner when the rotor is in the non-supporting position. That is, when the runner is temporarily placed on the temporary placement portion, the rotor is always at the non-supporting position. When the rotor is in the support position, the rotor interferes with placing the runner on the ceiling. No movers get in the way. That is, when the rotor is in the non-supporting position, the runner can be temporarily placed on the temporary placement portion, so that the worker can smoothly place the temporarily placed runner on the ceiling and temporarily fix it. be able to.

(5) A runner construction method according to the present invention includes a runner construction auxiliary tool attached to a rod-shaped construction member installed on a floor and a ceiling, wherein the runner is temporarily placed in a temporary placement portion, and the installation member. and a main body attached to the main body, which is rotatably held by the main body and is rotatable between a support position in which the tip of rotation faces the ceiling and a non-support position in which the tip of rotation faces away from the ceiling. It is held by a moving element and a rotating tip of the rotating element so as to be slidable along the radial direction of rotation from the center of rotation. A runner for attaching a runner to a ceiling using a runner installation aid comprising a slide member slidable between a protruding position and a biasing member for biasing the slide member toward the protruding position. construction method. The construction method of the runner includes a first step of constructing the construction member on the floor and the ceiling, a second step of attaching the runner construction aid to the construction member, placing the runner on a temporary placement portion, a third step of inserting a cable through a through-hole of the runner; a fourth step of rotating the rotor at the non-supporting position to the supporting position after the runner is positioned at the disposing position; and a fifth step of driving a screw into the runner.

The present invention can also be regarded as a runner construction method.

As shown in FIGS. 3, 4, and 5, the temporary placement plate 100 on which the runner 20 is temporarily placed has a rectangular plate shape extending obliquely upward when the rotor 80 is in the non-supporting position. . A lower end portion of the temporary placement plate 100 is fixed to a protruding tip portion of the holding plate 61 of the rotor holding portion 60 with a bolt 15 and a nut 16 . The temporary placement plate 100 extends obliquely upward from the tip of the projection of the holding plate 61 . The protruding tip of the temporary placement plate 100 is close to the main body plate 56 .

Temporary placement plate 100 has notch 101 into which side plate 22 or side plate 23 of runner 20 is fitted. The notch 101 is recessed obliquely downward from the upper end face of the temporary placement plate 100 when the rotor 80 is in the non-supporting position. The temporary placement plate 100 is an example of a temporary placement portion. When the rotor 80 is at the supporting position, the notch 101 faces obliquely downward, so the runner 20 cannot be temporarily placed on the temporary placement plate 100 when the rotor 80 is at the supporting position.

Next, the operation of attaching the runner 20 to the ceiling 11 by the operator will be described. A worker constructs a plurality of construction members 30 between the ceiling 11 and the floor 14 . The step of installing the installation member 30 by the worker is an example of the first step.

Next, the worker fixes the runner construction aid 40 to each construction member 30 . More specifically, after placing the rod-shaped portion 34 of the installation member 30 between the contact member 51 and the pressing plate 54 of the runner construction aid 40, the worker turns the blade screw 55 to move the runner construction aid. 40 is fixed to the installation member 30 . The step of attaching the runner construction aid 40 to the construction member 30 by the worker is an example of the second step.

Next, when the rotating element 80 is at the supporting position, the operator rotates the rotating element 80 to the non-supporting position. Then, the operator fits the side plate 22 or the side plate 23 of the runner 20 into the notch 101 of each temporary placement plate 100 of the plurality of runner construction aids 40, and temporarily places the runners 20 on the plurality of runner construction aids 40. do. The runner 20 is temporarily placed on the runner construction aid 40 by supporting the runner construction aid 40 at both ends in the longitudinal direction, for example. The worker passes the power cable extending from the ceiling 11 through the insertion hole 24 of the temporarily placed runner 20 . The step of temporarily placing the runner 20 on the temporary placement plate 100 and passing the power cable through the insertion hole 24 by the worker is an example of the third step.

Next, the worker removes the runner 20 temporarily placed on the runner construction aid 40 from the runner construction aid 40, presses the top plate 21 of the runner 20 against the ceiling 11, and moves the runner 20 to an appropriate mounting position. Deploy. For example, the worker arranges the runners 20 according to ink lines drawn on the ceiling. Alternatively, the operator may place the runner 20 at the mounting position by bringing the runner 20 into contact with a positioning member such as a regulating plate fixed to the ceiling.

Next, the worker rotates the rotor 80 in the non-supporting position to the supporting position in each runner construction aid 40 . When the rotating element 80 is rotated to the supporting position, the fourth piece 98 of the slide member 82 abuts against the top plate 21 of the runner 20, and the slide member 82 is slid and retracted from the projecting position. The slide member 82 that has slid contracts the pair of coil springs 83 . The compressed coil spring 83 presses the runner 20 against the ceiling 11 through the slide member 82 by its elastic force. The runner 20 is temporarily fixed by, for example, pressing both ends in the longitudinal direction against the ceiling 11 by the slide members 82 of the runner construction aids 40 . The temporarily fixed runner 20 is positioned by coming into contact with the positioning member described above. The step of temporarily fixing the runner 20 by rotating the rotor 80 to the support position by the operator is an example of the fourth step.

A worker drives a screw into the runner 20 temporarily fixed to the ceiling 11 to fix the runner 20 to the ceiling 11.例文帳に追加The step of fixing the runner 20 to the ceiling 11 by driving a screw into the runner 20 is an example of the fifth step.

[Action and effect of the embodiment]
In this embodiment, the worker can temporarily place the runner 20 on the runner construction aid 40 and pass the power cable through the insertion hole 24 of the runner 20 . Further, the worker rotates the rotor 80 of the runner construction aid 40 to the supporting position to temporarily fix the runner 20 to the ceiling 11 and drive a screw into the runner 20 to fix the runner 20 to the ceiling 11. . Therefore, the runner construction aid 40 can facilitate the worker's task of attaching the runner 20 to the ceiling 11 .

The rotating element 80 is located on the opposite side of the rod-shaped portion 34 of the bridging member 30 with the body plate 56 interposed therebetween. Therefore, when the worker rotates the rotor 80 in the work of fixing the runner 20 to the ceiling 11, the installation member 30 does not interfere.

Further, in this embodiment, the bolts 44 and 45 can hold the coil spring 83 and hold the slide member 82 slidably along the extending direction 18 . Also, the second nut 47 fastened to the bolts 44 and 45 prevents the slide member 82 from sliding beyond the projecting position. That is, it is possible to hold the coil spring 83, hold the slide member 82, and regulate the slide with a simple configuration of bolts and nuts.

The temporary placement plate 100 is fixed to the rotating plate 84 of the rotating element 80, and assumes a posture in which the runner 20 can be temporarily placed when the rotating element 80 is in the non-supporting position. That is, when the runner 20 is temporarily placed on the temporary placing plate 100, the rotor 80 is always in the non-supporting position. When the rotator 80 is in the support position, the rotator 80 becomes an obstacle to disposing the runner 20 on the ceiling 11 . The rotator 80 does not get in the way when arranging it in. That is, when the rotator 80 is in the non-supporting position, the runner 20 can be temporarily placed on the temporary placing plate 100, so that the worker can place the temporarily placed runner 20 on the ceiling 11 and temporarily fix it. Work can be done smoothly.
