Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support member for a top plate, which is used when a top plate such as a gypsum board is attached to a ceiling when a building is constructed.

[0002]

2. Description of the Related Art When building a building, there is a step of attaching a top plate such as a gypsum board to the ceiling. For example, to attach a top plate to a beam or the like stretched over the ceiling, the following was done. That is, a builder who climbed on a stepladder lifted the top plate and pressed it against the crosspiece from below, and screwed in the screw while pressing it with his own head. With this method, it was very difficult to do. And, for example, a gypsum board is 10-20 tatami mats in size.
There is also Kg and it is heavy. For this reason, it is extremely difficult to keep it fixed at an accurate position, and the top plate tends to shift during the work. I often had to start over. My neck got tired.

Therefore, the following support tools such as a top plate have been developed. That is, two small-diameter pipes having a diameter slightly smaller than that of the pipe are inserted into the vertically-standing pipe from above and below, respectively. A screw-in type stopper is provided at the upper end of the pipe, and a support plate is attached to the upper end of the small diameter pipe above. The lower small diameter pipe is urged downward by a coil spring.

This product is used as follows. First, stand vertically at a predetermined position, loosen the screw of the stopper, push up the small-diameter pipe above until the total length becomes slightly higher than the predetermined height, and then screw in the stopper to fix it.
Then, after the top plate or the like is applied to a predetermined position such as the ceiling, the pipe is pushed down while the coil spring is compressed, and the support plate is applied under the top plate in a state where the total length is slightly shortened. When the pipe is released from the pipe, the length of the pipe extends slightly due to the force of the coil spring, and the top plate or the like is elastically supported.

[0005]

Although the conventional support such as a top plate is convenient, it has the following drawbacks. First,
Strong coil springs were used to firmly support heavy objects. Therefore, a strong force was required to push down the pipe. Over time, not only did the arm become tired, but the gripping hand sometimes trembled, causing the top plate, etc. to shift from its predetermined position. For this reason, the position may have to be corrected many times.

[0006] Further, the stopper is used after it is loosened once and the length of the stopper is roughly determined, and then the stopper is tightened, but if the overall length is too short, the coil spring may not work sufficiently and may fall down. . It was very dangerous. Further, the height of the ceiling or the like from the position where the lower end of the support such as the top plate hits is not always constant. For this reason, the strength of the coil spring is different each time, and if the coil spring is weak, it may also fall. The problem to be solved by the present invention is to provide a support member for a top plate or the like that can easily and reliably support the top plate or the like without requiring much labor.

[0007]

Although such a problem has been solved in the present invention, the support for a top plate or the like according to the present invention is as follows. That is, the pipe 1 and the lower pipe 18 that fits in the pipe 1 are prepared, and the lower pipe 18 is fitted to the vertically arranged pipe 1 from below. Then, a stopper 19 having a hole of a size that fits the smaller diameter pipe of the pipe 1 and the lower pipe 18 is prepared, and the smaller diameter pipe is passed through the hole of the stopper 19 to make the stopper 19 One end side of the stopper is attached to the larger diameter pipe so that the stopper 19 can be swung up and down. When pushing up the pipe 1, the stop function of the stopper 19 does not work, and when the pipe 1 is released, the stop function works. Furthermore,
The support body 5 is attached to one or both of the upper side of the pipe 1 and the lower side of the lower pipe 18, and one or both of the support bodies 5 are urged vertically by a spring 3.

Further, the following supporting member such as a top plate may be used. That is, the pipe 1 and the lower pipe 18 that fits in the pipe 1 are prepared, and the lower pipe 18 is fitted to the vertically arranged pipe 1 from below. Then, a stopper 19 having a hole of a size that fits the smaller diameter pipe of the pipe 1 and the lower pipe 18 is prepared, and the smaller diameter pipe is passed through the hole of the stopper 19 to make the stopper 19 One end side of the pipe is attached to the larger diameter pipe side so that the stopper 19 can be swung up and down, and when pushing up the pipe 1, the stop function of the stopper 19 does not work and the stop function is released when the pipe 1 is released. Is working. Further, the supporting body 5 is attached to one or both of the upper side of the pipe 1 and the lower side of the lower pipe 18, and one or both of the supporting bodies 5 is provided with a female screw or a male screw on the pipe 1 / upper pipe 18 and the female screw or The screw rod 34 is screwed into the male screw, and the support member 5 is attached to the tip of the screw rod 34.
Is provided. When the threaded rods 34 are screwed into both the upper portion of the pipe 1 and the lower portion of the lower pipe 18, it is desirable that both the threaded rods 34 have reverse threads. One or both of the upper and lower supports 5 may be biased vertically by the spring 3.

Or, in the above-mentioned configuration,
The lower pipe 18 has a small diameter that fits inside the pipe 1,
The lower pipe 18 is fitted from below into the vertically arranged pipe 1, and the lever 12 is attached so as to rotate up and down with respect to the pipe 1, and the lower end is positioned near the tip of the stopper 19 and the lever 12 is gripped. The rod 14 that sometimes moves downward may be provided along the pipe 1.

Alternatively, the pipe 1 and the lower pipe 18 that fits in the pipe 1 are prepared, the lower pipe 18 is fitted onto the vertically arranged pipe 1 from below, and between the pipe 1 and the lower pipe 18. Is provided with a stopper mechanism, a support body 5 biased upward by a spring 3 is provided above the pipe 1, and a lever 12 is attached so as to rotate up and down with respect to the pipe 1 to support the lever 12. An interlocking mechanism may be provided between the body 5 side and when the lever 12 is gripped, the support 5 side may be pulled down via the interlocking mechanism.

In the above, a round pipe or a square pipe can be used as the pipe. Further, in what is referred to as a "stopper mechanism", various types of manual type and automatic type such as a swinging type and a screwing type can be adopted. In the case of the automatic swing type in all claims, the stopper itself may swing by gravity,
It may be allowed to swing by a spring. The stopper may be made of a spring material and may be rocked by its own elasticity.
Further, the support tool such as the top plate shown above can be used upside down by devising a stopper mechanism or the like.

[0012]

The support for the top plate and the like according to claim 1 is used as follows. First, the pipe 1 is pushed up until the total length is slightly longer than the predetermined length, and when the hand is released, the stop function of the stopper 19 is activated. Then, the top plate or the like is applied to a predetermined position, and the lower end of the lower pipe 18 is positioned below the top plate.
Then, after shortening the spring 3 while shortening the spring 3, the whole body is erected and released. The support 5 is pushed by the spring 3 and moves up and down to elastically support the top plate and the like. To remove
After compressing the spring 3 and shortening the overall length, the entire body is slightly tilted and removed.

According to the second aspect of the present invention, the top plate or the like is placed at a predetermined position so that the support is set up at a predetermined position, and the pipe 1 is pushed up so that the upper end is brought into contact with the bottom face of the top plate or the like. Then, the pipe 1 and the like and the screw rod 34 are relatively rotated to extend the entire length and obtain a sufficient supporting force. When removing, do the reverse operation. In the third aspect, when the lever 12 is gripped, the rod 14 descends, and the lower end of the rod 14 pushes the tip of the stopper 19 to release the stop function. Claim 4
In the one described in (1), when the lever 12 is gripped, the spring 3
While pushing down, the upper support 5 is pulled down to shorten the total length. When the lever 12 is stopped after the lever 12 is held at a predetermined position by holding the lever 12, the upper support 5 is pushed upward by the spring 3 and elastically supports the top plate and the like.

[0014]

EXAMPLE 1 Example 1 will be described with reference to FIG. 1 indicates a slightly long pipe. A pin 2 is mounted horizontally above the pipe 1 and a spring 3 is fitted in the pipe 1 on the pin 2. An upper pipe 4 having a diameter slightly smaller than that of the pipe 1 is fitted from above the pipe 1. A disc-shaped support 5 is attached to the upper end of the upper pipe 4 so as to be swingable, and a rubber plate 6 is attached on the support 5.

The rear end of the rotating rod 7 is attached by a pin 8 in the middle of the pipe 1, and the rotating rod 7 is substantially horizontal. Then, the lower ends of the upper and lower rods 9 are attached to the tip of the rotating rod 7 with pins 10, and the upper ends of the upper and lower rods 9 are attached to the upper pipe 4 with pins 11. The upper end of the lever 12 is attached to the tip of the rotating rod 7. Lever 1 on the side of pipe 1
The guide 13 is attached in the vertical direction so as to be along the line 2, and the elongated rod 14 is fitted in the guide 13. The upper end of the rod 14 is located slightly below the rotating rod 7, and a male screw is cut around the lower end and the female screw rod 15 is screwed into the male screw.

A support rod 16 is attached to the lower end of the pipe 1 facing downward, and a pin 17 is attached near the lower end of the support rod 16. A lower pipe 18 having a diameter slightly smaller than that of the pipe 1 is fitted into the pipe 1 from below. Then, a stopper 19 having a hole having a diameter slightly larger than the outer diameter of the lower pipe 18 is prepared, and the stopper 19 is arranged on the outer periphery of the lower pipe 18 with the lower pipe 18 fitted in the hole. A slit 20 is formed on one end side of the stopper 19, and the stopper 17 is attached to the support rod 16 with the pin 17 of the support rod 16 fitted in the slit 20. A coil spring 21 is attached between the support rod 16 and the stopper 19 to urge the tip side of the stopper 19 upward. The lower end of the female screw rod 15 is located above the tip of the stopper 19. The support 5 is attached to the lower end of the lower pipe 18 so as to be able to swing.

The support such as the top plate described above is used as follows when the top plate is stretched, for example. For example, a builder who rides on a stepladder places the lower support 5 at a position directly below where he is going to stretch the top plate, and grips the lever 12. When the lever 12 rotates toward the pipe 1, the rotating rod 7 rotates downward about the pin 8 and the rotating rod 7 pulls down the upper and lower rods 9. The upper pipe 4 is pulled down while compressing the spring 3. On the other hand, when the rotating rod 7 further rotates downward, the upper end of the rod 14 is pushed down. When the lower end of the female screw rod 15 screwed into the lower end of the rod 14 pushes down the stopper 19 slightly, the stop function of the stopper 19 is released. Here, when the pipe 1 is pushed up, the portion such as the pipe 1 is pushed up with the lower pipe 18 left below. Then, the rubber plate 6 is pressed against the ceiling or the like at an appropriate position where the portion where the top plate is stretched is slightly removed, and the lever 12 is released. The coil spring 21 pulls up the stopper 19 so that the stop function works and the pipe 1 and the like are prevented from descending, and at the same time, the rubber plate 6 and the like are pushed up by the spring 3 and closely contact with the upper side, so that the whole is firmly self-supporting. Here, after the top plate is lifted and pressed at a predetermined position, the support member such as the top plate is again held and the lever 12 is grasped. When the rod 14 releases the stop function of the stopper 19, the pipe 1
Etc. are slightly lowered, and the upper rubber plate 6 is shaken around the center of the top plate about the lower support body 5. Then pipe 1
Etc. are pushed up and the rubber plate 6 is pressed against the lower surface of the top plate,
Stop gripping the lever 12. At the same time that the stopper 19 exerts a stopping function, the elastic force of the spring 3 also works to firmly support the top plate. Here, the same work of fixing the top plate by screwing in screws and fixing the next top plate is performed. In this way, the top plate is stretched one after another.

The structure of the first embodiment can be mechanically used upside down. The reason why the female screw rod 15 is screwed into the lower end of the rod 14 is to adjust the elasticity of the spring 3 when supporting the top plate and the like. For example,
If the female screw rod 15 has been moved downward, the lever 1
When 2 is gripped, the lower end of the female screw rod 15 releases the stopping function of the stopper 19 when the spring 3 is slightly compressed.
When the rubber plate 6 is pressed against the top plate or the like to be supported as it is, the elasticity of the spring 3 is weak. On the contrary, as the female screw rod 15 is raised, the elastic force at the time of supporting becomes stronger.

Second Embodiment A second embodiment will be described with reference to FIG. In the second embodiment, the stopper 19 is of a screw type. Then, the upper end of the lever 12 is attached to the pin 8 attached to the side portion of the pipe 1. A vertical slit 22 is formed in the pipe 1, and the head of a pin 23 attached to the upper pipe 4 is exposed through the slit 22. The pin 23 is located below the lever 12. As in the first embodiment, the spring 3 is fitted under the upper pipe 4, and the lower end of the spring 3 is received by the pin 2. A suction cup-shaped support 5 is attached to the upper end of the upper pipe 4 so as to be swingable.

The device of Example 2 is used as follows.
First, the stopper 19 is twisted and loosened, the lower pipe 18 is pulled out from the inside of the pipe 1, and the stopper 19 is screwed and fixed when the total length is set to be slightly longer than a predetermined length. Next, the lever 12 is gripped, and the upper pipe 4 and the like are pulled down via the pin 23 to stand in a predetermined position, and the grip of the lever 12 is released. The upper pipe 4 and the like are lifted by the force of the spring 3, and the upper support 5 pushes the lower surface of the top plate or the like to firmly support it. The device of the second embodiment can also be mechanically used upside down.

Third Embodiment A third embodiment will be described with reference to FIG. The third embodiment is basically the same as the first embodiment. However, a crank mechanism is used instead of the lever mechanism. The upper pipe 4 and the lower pipe 18 are fitted in the pipe 1 from above and below, respectively.
The upper pipe 4 is biased upward by a spring 3. The same stopper mechanism as that of the first embodiment is provided between the pipe 1 and the lower pipe 18. Then, the large diameter pipe 24 is fitted on the outer circumference of the pipe 1, and the lower end of the rod 25 is attached by the pin 26 on the side surface of the large diameter pipe 24. The upper end of the rod 25 is connected by a pin 28 to one end of another rod 27 arranged in a substantially horizontal direction. The middle of the rod 27 is attached to the pipe 1 by a pin 29, and the other end of the rod 27 is connected to the lower end of another rod 30 by a pin 31. The upper end of the rod 30 is connected to the upper pipe 4 by a pin 32.

The device of Example 3 is used as follows.
The top plate or the like is applied to a predetermined position, the lower end of the lower pipe 18 is placed at a predetermined position and is vertically erected, and the large diameter pipe 24 is pushed up. Even after the support 5 hits the lower surface of the top plate or the like, it is further pushed up. The large diameter pipe 24 is connected to the rod 2 via the rod 25.
One end of 7 is pushed up, and the other end of rod 27 is pulled down.
The rod 30 is pulled down, and the upper pipe 4 and the like are pulled down while compressing the spring 3. Release the spring when the spring 3 has sufficient elasticity. The pipe 1 and the like are prevented from descending by the stopper 19, and the support body 5 pushes and supports the lower surface of the top plate or the like by the force of the spring 3.

Fourth Embodiment A fourth embodiment will be described with reference to FIG. The stopper mechanism used in the first embodiment does not use the coil spring 21. When pushing up the pipe 1, the stop function of the stopper 19 does not work, and at the moment when pushing up is stopped, the stop function works to prevent the pipe 1 from falling. When pulling down the pipe 1, the tip of the stopper 19 is slightly pushed down to release the stop function. Then, a nut 33 is fitted and attached inside the upper end of the pipe 1. The screw rod 34 is passed through the center of the suction cup-shaped support 5 from above, and the screw rod 3
The lower end of 4 is screwed into the nut 33. A spring bearing 35 is provided in the middle of the screw rod 34, and the spring 3 is fitted between the support 5 and the spring bearing 35. The nut 33 is also fitted inside the lower end of the lower pipe 18, and the screw rod 34 is screwed into the nut 33 from below. The upper and lower screw rods 34, 34 are reverse threads. The rubber support 5 is attached to the lower end of the lower screw rod 34.

The device of Example 4 is used as follows. The pipe 1 is pushed up in a predetermined position, the spring 3 is compressed and the upper support 5 is pressed against the top plate or the like, and then the hand is released. Stopper 19 when pushing up the pipe 1
Since the stop function does not work, the pipe 1 can be pushed up freely, and when the hand is released, the stop function works to prevent the pipe 1 and the like from falling. Then, at this time, if it is in a state where it can be sufficiently supported by the force of the spring 3, it is supported as it is. If the bearing capacity is not sufficient, pipe 1 / lower pipe 18
Turn to make the upper and lower screw rods 34, 34 project little by little, so that they are firmly supported. When removing it, it is sufficient to push down the upper end of the stopper 19 a little. The stop function is released and the pipe 1 and the like descend. The device of the fourth embodiment can also be mechanically used upside down.
Further, the mechanism for urging the support body 5 with the spring 3 can be provided not at the upper portion but at the lower portion, or both at the upper and lower portions.

Fifth Embodiment A fifth embodiment will be described with reference to FIG. The lower pipe 18 is fitted from below the pipe 1, and the support rod 1 is provided below the pipe 1.
The stopper 19 is attached at 6. A nut 33 is fitted inside the upper end of the pipe 1. Although a separate threaded rod 34 is prepared, male threads, which are reverse threads, are formed in the upper portion and the lower portion of the threaded rod 34, respectively. Further, the upper pipe 4 is attached below the upper support body 5, and the nut 33 is fitted inside the lower end of the upper pipe 4. The nut 33 has a reverse thread to the nut 33 of the pipe 1. And

Then, turn the screw rod 34 to rotate the upper pipe 4 and the pipe 1.
Widen the space between and to support the top plate firmly. Also in the fifth embodiment, springs may be incorporated in the upper support 5 or the lower support 5, or both upper and lower springs may be incorporated.

[0026]

In the support for the top plate and the like according to claim 1, an automatic stopper mechanism is adopted. The work of pushing up the pipe 1 and the like is easy, and the entire length can be easily made a predetermined length. Also, while compressing the spring 3, the pipe 1
An elastic support force can be obtained by pushing up and releasing the hands. Therefore, the operation is really simple. The second aspect also has the advantage of the automatic stopper mechanism. Further, there is an advantage that a sufficient supporting force can be obtained only by relatively rotating the pipe 1 and the screw rod 34. According to claim 3,
The stop function of the stopper 19 can be released by grasping the lever 12. Therefore, it is excellent in workability. According to the fourth aspect of the present invention, the lever 1 is used to compress the spring 3.
All you have to do is hold two. Similarly, workability is good.
