Description

[Detailed Description of the Invention] The present invention relates to a foundation top leveling ruler that can easily and accurately level the foundation top.

When constructing a building, especially a factory-produced house, it is desirable to ensure that the top of the foundation is leveled. Then,
When leveling the top of the wooden formwork, nails are driven into the top of the formwork, and magnets are used to form the steel formwork. Since these are dot markings, it is difficult to do it accurately and beautifully unless you are an expert. Finishing is difficult, especially in the case of ribbed formwork, which requires labor.

The present invention is a foundation top leveling ruler that is fixed to the formwork and can guide the trowel in the horizontal direction to easily and accurately perform foundation top leveling work. and a soldering iron guide portion for guiding a soldering iron, the long body having an L-shaped cross section, the fixing portion having a long groove formed on the iron guiding portion side in parallel with the iron guiding portion. The present invention provides a base top leveling ruler in which through holes are provided at appropriate intervals in the long groove.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the basic top leveling ruler of the present invention shown in the drawings will be described below.

Figures 1 and 2 show an embodiment of the present invention, in which 2 is a plate-shaped fixing part, 3 is a plate-shaped soldering iron guide, and the base top leveling ruler of the present invention is shown. 1 is formed into an L-shaped cross section by a fixing part 2 and a soldering iron guide part 3, and a long groove 2' is formed in the fixing part 2 on the iron guiding part 3 side in parallel to the soldering iron guiding part 3. It is composed of a long body in which through holes 2'', 2'', . . . are formed at appropriate intervals. The long groove 2' is connected to the fixing part 2 by the fixing fitting 10 shown in FIG.
It is provided to be fixed to the inside of the steel formwork 20 shown in the figure, and has a size that allows a later-described clamping tip 11' of the fixture 10 to fit therein.
The through holes 2''2'', . . . are sized to form nail through holes when fixing the fixing portion 2 to the inside of the wooden formwork by nailing.

Fig. 6 shows a fixing fitting 10 used when fixing the foundation top leveling ruler 1 of the present invention to a steel formwork. A clamping arm 13 is a cylinder fixed to one clamping arm 11 and has a rotatable nut portion 14 at one end; 15 is the other clamping arm 11;
The fixing metal fitting 10 is a spacing adjustment member that is engaged with the cylindrical body 13, penetrates the cylinder body 13, and is screwed onto the nut portion 14.
By changing the degree of threading between the spacing adjusting member 15 and the nut portion 14, the spacing between the clamping tips 11', 11' of the lower ends of the clamping arms 11, 11 can be adjusted.

Therefore, when using the foundation top leveling ruler 1 having the above structure, as shown in FIG. The foundation top leveling ruler 1 is fixed at a predetermined height, and the upper surface of a foundation forming material (not shown) such as concrete poured between a pair of formworks 20 (one not shown) is placed on the trowel guide section. 3. Solder the iron 30 along the top.
All you have to do is move it, and if you do it like this,
Easy and accurate top leveling work can be performed. Note that the fixing fittings 10 can also be used for wooden formworks, and in order to fix the base top leveling ruler 1 to the formwork 20, whether made of steel or wood, the spacing adjustment material 15 and nuts are used as described above. Adjust the degree of screwing of part 14,
The pair of clamping tips 11', 11' allow the fixing part 2 to
The formwork 20 may be held between both sides. In this case, one clamping tip 11'
It is only necessary to fit the clamping member into an appropriate position in the long groove 2' of the fixing part 2, and to bring the other clamping tip part 11' into contact with the outside of the formwork 20.Although the fixing bracket 10 is not shown, there are usually a plurality of fixing brackets 10. Use one. Further, when the formwork 20 is particularly a wooden formwork, the foundation top leveling ruler 1 can also be fixed to the formwork 20 by nailing through the through holes 2'', 2'', .

In addition, FIGS. 3 and 4 show a base top leveling ruler 1 that is applied to a ribbed formwork in which vertically long concave portions and convex portions are alternately formed in the horizontal direction, unlike the formwork shown in FIG. The ruler 1 shown in the same figure has projecting plates 5, 5, . It is fixed at an angle that roughly bisects it. Therefore, if this ruler 1 is used, the veneer 5,
Since 5,... fit into the above-mentioned recesses, the foundation forming material does not protrude above the veneers 5, 5,... during the top leveling work, and the ribbed foundation has an approximately 45-degree chamfer on the upper edge. can be formed. In addition, the veneer 5,
5, . . . may be provided horizontally instead of diagonally as shown.

As mentioned above, the base top leveling ruler of the present invention can be fixed to steel formwork and wooden formwork, and according to the ruler of the present invention, it is possible for skilled workers to simply level the top of the trowel guide with a trowel. The top leveling work can be done easily and accurately without the need for the top leveling work, and the top leveling work can be done at the same time as the foundation forming material is poured, and there is no need to perform the top leveling work again, so the foundation leveling work can be done easily and accurately. It is possible to shorten the construction period from formation to house construction, and in particular, by using a foundation top leveling ruler with a veneer as in the example, the leveling work of the top of a ribbed foundation can be greatly improved. Practical effects can be achieved.
