Description

[Detailed description of the invention] This invention relates to a joint width adjustment tool used to adjust the joint width in stone laying work such as attaching marble to the exterior walls of a building.

Conventionally, in stone pasting work such as pasting marble onto the outer wall of a building, stones are pasted at predetermined intervals and the gaps between the stones are filled with joint material using a joint trowel. In other words, the stones are connected by joints.

These joints are necessary to absorb distortions in the outer wall (framework) of the building and irregularities in stone dimensions. Conventionally, the joints were created by inserting pieces of wood or the like between the stones, or by using the worker's visual sense. The gap between the stones (joint width) is adjusted, and the gap is filled with joint material using a joint trowel.

For this reason, if the joint width differs depending on the degree of distortion of the building structure or the size of the stones, it is necessary to cut a piece of wood and insert it between the stones, which is a very troublesome process. This reduces the efficiency of stone laying work, and there are many errors due to the operator's visual perception, which may prevent the joint trowel from entering and fill the joint material neatly, resulting in poor joint finish. It ends up.

The present invention was developed in view of the above circumstances, and its purpose is to provide a joint width adjustment tool that can easily adjust the gap between stones to different widths and can be used repeatedly. That's true.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an overall perspective view, in which the lower surface 2 of the thin plate-like main body 1 is a flat surface, the upper surface 3 is stepped, and both side surfaces 4 are parallel to each other, and the lower surface 2 and the upper surface 3 are parallel to each other. The longitudinal end surfaces 5 and 6 are flat surfaces that are perpendicular to each surface.

The upper surface 3 includes a first parallel surface 7 ₁ parallel to the lower surface 2 and a first inclined surface 8 inclined with respect to the lower surface 2.
₁ , the second parallel surface ₇₂ , the second inclined surface ₈₂ , the third parallel surface ₇₃ , the third inclined surface ₈₃ , and the fourth parallel surface ₇₄ are successively formed in the longitudinal direction, and the lower surface 2 The distances L 1 , L 2 , L 3 , and L ₄ of the first, _second , third, and fourth parallel surfaces _{7 1} , 7 ₂ , _{7 3 ,} and 7 ₄ become shorter in sequence.

That is, upper and lower parallel surfaces having different heights are sequentially formed in the longitudinal direction of the thin plate-like main body 1.

As shown in FIG.
are in contact with each other, and any one of the parallel surfaces 7 ₂ (7 ₁ , 7
₃ , 7 ₄ ) to adjust the gap _t1 between the stones 10 and 11 by abutting the lower end surface 11a of the stone 11.

After this, the gap _t1 is filled with joint material using a joint iron.

In addition, when adjusting the gap between the stones 10 and 11, insert the lower surface 2 of the main body 1 and any one of the parallel surfaces 7 ₁ to 7 ₄ between the stones 10 and 11 to close the gap. Just adjust it.

As described above, the joint width can be adjusted to different joint widths using one joint width adjustment tool.

In addition, once the joint width is adjusted, it can be removed from between the stones 10 and 11 and reused, so it can be used repeatedly.

Furthermore, narrow grooves 9 are formed at positions near the end faces 5 of the first parallel surfaces ₇₁ of the lower surface 2 and the upper surface 3, respectively, to make the surfaces rough, so that they are easy to hold in the hand and do not slip when being inserted or removed.

In order to manufacture the joint width adjuster described above, it is sufficient to extrude a long material having the same cross-sectional shape as the main body 1, manufacture it by pultrusion molding, etc., and then cut the long material into a predetermined width.

The present invention is as described above, and with a single joint width adjustment tool, the gap between stones can be easily adjusted to different widths, and stone pasting work can be carried out efficiently, and it can be reused repeatedly. It is possible and economical.
