[Problems to be solved by the invention]
Therefore, the present invention provides an inexpensive top end display material that can be attached to the vertical stripes with a single touch, can be easily adjusted up and down along the vertical stripes, and can be used even when the horizontal stripes are fixed to the upper end. Is.
[0004]
[Means for Solving the Problems]
For this reason, this invention displays the top end level of concrete, such as a cloth foundation of a building, and forms the insertion part which can be inserted in the vertical bar of a reinforcement bar by bending a line object, such as a steel wire. while, be one obtained by the crest display unit capable of projecting an upper end above the vertical stripe, insertion portion, lateral stripes to be inserted is inserted from the top of the vertical stripe fixed at the upper end and the lower end Fold up, turn back down again, and turn up again to make each folded part into an elongated U-shaped loop body, facing each other so that the vertical bars can be sandwiched between the two loop bodies at the lower end It is the concrete top end display material of the made structure .
Alternatively, the spiral portion that can accommodate the vertical stripes may be an insertion portion that is bent, and the vertical stripes may be inserted into the spiral portion while the horizontal stripes are rotated horizontally from above the vertical stripes fixed at the upper end. . Furthermore, the upper end may be folded back, and the top end and other levels may be displayed at two places, the folded upper end and the folded tip.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, details of the present invention will be described with reference to illustrated embodiments. The embodiment shown in FIGS. 1 to 3 is formed by bending one steel wire, and the upper end of the straight portion 1 is folded back about 1 cm to form the top end display portion 2 and the lower end portion is a vertical bar. As the insertion portion 3 to the, it is continuously connected.
[0006]
The insertion portion 3 has a shape in which the lower end of the straight portion 1 is folded upward 3-4 cm, then folded downward, folded upward again, and the end portion is directed upward. Since the folded portion is semicircular, each of the folded portions becomes an elongated U-shaped looped folded portion. Therefore, the lower loop bodies 32 and 33 are continuously formed on both sides of the upper loop body 31.
[0007]
Further, the lower loop bodies 32 and 33 are arranged to face each other to form an opening at the bottom end, and the bottom ends of the loop bodies 32 and 33 are inclined slightly outward as shown in FIG. In addition to an insertion guide that widens the opening, the folded portion that is the upper end of the upper loop body 31 is slightly inclined outward to serve as a guide for upward movement. Further, as shown in FIG. 3, the narrow widths of the loop bodies 32 and 33 on both sides are made slightly narrower as it goes upward, and as shown in FIG. 2, the narrow width of the upper loop body 31 is made slightly narrower as it goes downward. Thus, the insertion portion 3 is elastically biased inward.
[0008]
As shown in FIG. 4, this example display material S configured as described above can be inserted into the vertical bars 5 by one-touch by inserting them into the vertical bars 5 of the fabric foundation reinforcement of the building from above. That is, by inserting the longitudinal bars 5 into the longitudinal bars 5 through the openings between the loop bodies 32 and 33 of the insertion part 3, both sides of the longitudinal bars 5 are supported by the loop bodies 32 and 33 as shown in FIG. Is supported and clamped by the upper loop body 31. In addition, since the insertion portion 3 spreads slightly outward by insertion into the longitudinal muscle 5, the longitudinal muscle 5 is strongly elastically held by its elastic restoring force.
[0009]
In addition, even when the horizontal bar 6 is welded to the vertical bar 5 as shown in FIG. 4, the position where the linear part 1 and the loop bodies 32, 33 on both sides do not contact the horizontal bar 6, that is, the loop body 31 at the upper position. If it is inserted in a state of being arranged on the side opposite to the horizontal stripe 6, it can be inserted into the vertical stripe 5 regardless of the horizontal stripe 6.
[0010]
After holding the vertical stripe 5, the display material S may be slid up and down along the vertical stripe 5 so that the top end display section 2 at the upper end is positioned at the measured height. This raising and lowering is smoothly performed without being caught by the deformed protrusion 51 of the vertical bar 5 because the folded portion at the tip of each loop body 31, 32, 33 faces outwards due to the flexible holding by the spring pressure. You can move. Also in this case, it can move up and down regardless of the presence of the horizontal stripes 6.
[0011]
Furthermore, since the top end display portion 2 at the upper end can be folded to display the two levels of the folded upper end 21 and the folded tip 22, for example, in the case of a concrete cloth foundation, the lower folded tip 22 is set as the top end level display for placing a live concrete. The upper folded upper end 21 may be constructed as a mortar finish level display.
[0012]
Note that the stop ring 4 may be locked to the upper end of the vertical bar 5 as shown in FIG. Further, when the horizontal stripe 6 is bound and fixed to the vertical stripe 5 with the string 7, the string 7 is obstructed and the display material S cannot be inserted from above, so that the insertion portion 3 is inclined as shown in FIG. If it is inserted into the vertical stripe 5 and then rotated upward, it can be inserted as shown in FIG.
[0013]
Next, another example display material K shown in FIG. 7 will be described. It is formed by bending one steel wire, and the upper end of the straight portion 1 is folded back about 1 cm to form the top end display portion 2, and the lower end portion is used as the insertion portion 30 to the vertical stripe 5. Is formed in a spiral shape that can be inserted and accommodated. Note that the opening of the spiral portion is slightly widened toward the lower end to facilitate insertion of the vertical stripe, and the opening is slightly narrowed so that the vertical stripe 5 can be elastically held above the spiral portion.
[0014]
In this example, the vertical streak 5 is accommodated and held by the spiral insertion portion 30 by being lowered from the top of the vertical streak 5 while being rotated horizontally. At this time, since the opening of the lower end spiral part is slightly wide, the vertical stripe 5 can be easily inserted, and since the opening is slightly narrow above the spiral part, the vertical stripe 5 can be elastically held. In addition, even if the horizontal muscle 6 is bound with a string or the like, it can be inserted into the longitudinal muscle 5 without any trouble. Further, the height adjustment may be performed by grasping the straight portion 1 and moving it up or down, or moving it up and down while rotating it.
[0015]
Although each embodiment has the above-described configuration, the present invention is not limited to this. For example, the material of the striatum is not limited, and it may be made of metal or plastic as long as it can provide springiness. Further, the shape of the top end display section at the upper end is also appropriate. Furthermore, the shape of the insertion part is also arbitrary, as long as it can hold the vertical stripes. In addition, you may use for the display of the top level of various concrete other than the top level of the cloth foundation of a building.
[0016]
【The invention's effect】
According to the first aspect of the present invention, it can be easily inserted into the longitudinal bar of the reinforcing bar simply by inserting from above, and can be attached even when the horizontal bar is arranged at the upper end of the vertical bar. According to the second aspect, even when the horizontal stripe is bound with a string or the like, it can be attached from above. In claim 3 , two levels such as a live concrete placement level and a finishing level can be displayed.
