Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a pulling hammer, and more particularly to a pulling hammer used at the time of building a wooden building.

[Conventional technology]

A device shown in FIG. 10 is conventionally known as this type of device.

1 is a body of a pulling hammer, 2 is a rod-shaped body of the body 1, 3
Is a hammer attached to the tip portion 2a of the rod-shaped body 2, 4 is a steady rest fixed to the tip portion 2a, 5 is a hand-holding portion at the lower portion of the rod-shaped body 2, and 6 is slidable on the frame rod-shaped body 2. The fitted tubular body 7 is a latch fixed to the tubular body 6, and the tubular body 6 is hung by hooking the latch 7 on a girder 8 or the like. Reference numeral 9 is a ring provided on the outer wall of the tubular body 6, and the steady rest 4 is passed through the ring 9.

When the rod-shaped body 2 to which the hammer 3 is attached is lowered by the hand-held portion 5 during use, the steady rest 4 is guided by the ring 9 and the rod-shaped body 2 slides downward in the tubular body 6. 10 is a foundation made of concrete, 11 is a foundation placed on this foundation 10, 11a is a foundation hole provided in this foundation 11, 12 is a pillar, 12a and 12b are provided above and below the pillar 12, respectively It is a tenon. 8a is a girder hole provided in the girder 8. The tenon 12a of the pillar 12 is in the girder hole 8a, and the pillar is in the base hole 11a.
Insert 12 tenons 12b respectively.

In use, for example, first move the rod-shaped body 2 upward by hand, hook the latch 7 on the girder 8 and release the rod-shaped body 2 from the hand as shown in FIG. The pull hammer is suspended by contacting the beam 8.

When working, hold the hand holding part 5 and raise the pulling hammer upward,
Next, the rod-shaped body 2 is released downward, and the hammer 3 is dropped downward, thereby giving an impact to the girder 8.

The driving work is performed by repeating the above work. In the pulling hammer of this example, since the latch 7 is provided, even a considerably heavy pulling hammer can be easily hooked on the girder 8 by hand, and the rod-shaped body 2 can be guided along the steady rest 4 by Since it slides inside 9, the pulling hammer 3 is simply pulled downward, and the action of gravity acting on the pulling hammer 3 is added, so that the work can be easily performed by a simple operation.

[Problems to be solved by the device]

However, in the case of the conventional pulling hammer, a) during work, the rod-shaped body 2 with the heavy hammer 3 attached to the tip 2a is lifted by hand, and the tenon 12a of the column 12 is inserted into the girder hole 8a.
When inserting the hammer, it is difficult to set the hammer 3 at a position where it can be effectively driven, and if the hammer 3 is reset again, there is a problem that the neck portion is easily squeezed.

B) On the pillar 12, mount the unillustrated girder on the second floor so that the girder can be lifted up by a crane when connecting, so that the girder will be in a position that facilitates the driving work.
However, there was a problem that it took a lot of skill to set it, and it was difficult to do it easily in a short time.

C) Furthermore, in the work of connecting the girders to each other, it is required to set the overlapping part almost horizontally and to complete it within a limited time when the ridge is built, but this is difficult to carry out. There was an occasion.

The present invention has been made to solve such a problem, and a hammer attached to the tip of a rod-shaped body has a prying and non-slip protrusion projecting on the top, and a guide and a rope on the side. An object of the present invention is to provide a pulling hammer that can be properly and easily and safely completed in a short time by slackening it so that the rod can be added to and removed from the rod-shaped body to attach and detach the rod.

[Means for Solving the Problems]

For this reason, in the pulling hammer of the present invention, the hammer attached to the tip of the rod-shaped body is provided with a prying and anti-slip projection at the upper part, and a guide portion and a rope loosening are provided on the side portion, and the rod-shaped body has It is configured so that the next addition bar can be attached and detached.

[Action]

In the above structure, the hammer is provided with a prying and anti-slip protrusion so that the object can be plucked at a position where it can be easily driven and can be held without slipping. , Easy to set the work object, and work so that the driving from below can be performed correctly.

Furthermore, by adding the rod to the rod-shaped body so that the rod can be attached and detached, it is possible to work with the tenon at the high place such as the second floor in a position where it is easy to drive the tenon into the equal tenon of the pillar. The part is set almost horizontally, and work is done so that the driving work can be done safely and easily within the limited time when it is on the upper ridge.
