DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to an operation for attaching a brick tile to an outer wall of a concrete building or the like.
The present invention relates to a resilient plate-like metal fitting driving tool used when fixing each brick tile to a mounting plate on a wall surface.

[0002]

2. Description of the Related Art Generally, a construction method of attaching a brick tile to an outer wall of a concrete building involves applying a mortar to a base surface of an outer wall and embedding a brick tile in the mortar.
There was a method of drying and fixing. Instead of this construction method, a metal mounting plate such as aluminum is stretched on the outer wall base surface, and a brick tile is fitted into a mounting groove formed on the mounting plate, and the brick tile is removed from the mounting plate. In order not to fall off, the elastic plate-like metal fitting which is curved in the shape of an arc is pushed into the gap formed between the upper surface of the brick tile and the mounting groove, and the elasticity of the elastic plate-like metal fitting causes the mounting plate to be bent. Construction methods for fixing brick tiles in mounting grooves have also been implemented.

According to the construction method using such a resilient plate-like metal fitting, the gap between the mounting groove and the brick tile is very narrow, whereas the top of the resilient plate-like metal fitting is higher than the gap.
In addition, since the elastic force is large, the work of deforming and pushing the elastic plate-like metal fitting into such a narrow gap into a flat plate shape against the elastic force requires considerable force and skill. Further, since about 70 such metal fittings are required per 1 m ² , the means of individually pushing them in manually has a disadvantage that the work efficiency is low, the construction period is lengthened, and the construction cost rises. In view of the above, conventionally, there has been proposed a tool capable of instantly driving a resilient plate-shaped metal fitting by using compressed air. As shown in FIG. 6, the driving tool 51 uses compressed air for moving the elastic plate-shaped metal fittings M, M... Back and forth with a tool body 52 and a driver 53 for driving each elastic plate-shaped metal fitting M. It comprises a driving mechanism 54 composed of a cylinder and a piston, and a fitting holder 55 for accommodating a large number of resilient plate-shaped fittings M on the upper part of the tool body 52. The tool main body 52 has a structure in which a curved resilient plate-shaped metal fitting M is extended in a flat plate shape and can be directly driven into a gap between a mounting groove and a brick tile.

[0004]

However, the above-mentioned conventional driving tool 51 requires a large-sized compressor which always sends out compressed air at the time of construction, so that the apparatus becomes large-scale, and the operation noise of the compressor during operation is reduced. There was a problem that it also caused noise. Further, since the driving mechanism 54 using the compressed air has a strong impact force,
There was also a problem in that if the elastic plate-shaped metal fitting was applied to the hand during work, serious injury was likely to occur.

On the other hand, a driving tool having a built-in driving machine such as a motor is also conceivable. However, the driving tool having a built-in driving machine becomes heavy, and an operator needs to move such a heavy driving tool toward a wall surface. Holding the device for a long time deteriorates the workability, complicates the structure of the driving tool, increases the number of parts, and requires maintenance and inspection.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and can securely and quickly fix each brick tile in an operation of attaching a brick tile to an outer wall of a concrete building with a simple structure. An object of the present invention is to provide a driving tool for a resilient plate-shaped metal fitting.

[0007]

In order to achieve the above object, a driving tool for a resilient plate metal fitting according to the present invention is formed with a tool main body and a lower portion of the tool main body so as to project downward. In a driving tool comprising a grip and a metal holder for accommodating a large number of resilient plate-shaped metal fittings at a front portion of the tool main body, a driver punching out the driver so that the tool main body slides in the front-rear direction. Form a passage
A fitting ejection passage is provided on an extension of the driver ejection passage, and a fitting supply passage is opened at an upper portion of the fitting ejection passage. The grip is capable of swinging a lower end of a link lever. In addition to the above, the driver is connected to the upper end of the link lever, and an elastic member is interposed so as to urge the link lever to the rear of the tool body. A supply passage formed at an upper portion of the metal fitting ejection passage so as to protrude upward, and holding a resilient plate-shaped metal fitting so as to communicate with the metal fitting supply passage of the metal fitting ejection passage. It is the gist.

According to the above construction, the resilient plate-shaped metal fitting supplied from the metal fitting holder and the metal fitting supply path into the driving path is used to drive the driver from the driver driving path by gripping the link lever of the grip. As a result, the metal is passed through the metal-ejecting passage and is ejected from the front end side opening.
When the resilient plate-shaped metal fitting passes through the metal fitting-out path, the rear end opening end of the metal fitting-out area on the driver launching path side supplies one bullet supplied into the driver launching path. While the sprung metal plate is formed in a size that can enter,
The front-side open end is formed to be lower than the height of the resilient plate-shaped metal fitting in the supply state and longer than the length of the resilient plate-shaped metal fitting, and the rear-side open end and the front-side open end are formed. The resilient plate-shaped metal fitting is pressed at its curved top by the inclined surface, and the entire body is forcibly compressed and stretched into a flat plate shape. It returns to the original bent state by the force.

As described above, according to the driving tool, since the resilient plate-shaped metal member is driven in a compressed state, it can be easily driven into a narrow gap. Therefore, when constructing a brick tile, align the tip side opening with the gap between the brick tile and the mounting groove, and use a driving tool to
A resilient plate-shaped metal fitting can be easily driven into this gap. The driven elastic plate-like metal fitting attempts to return to its original state in the groove by its elastic force, so that the brick tile can be securely fixed in the mounting groove of the mounting plate.
