Description

  The present invention relates to a level marker for allowing a concrete surface to be placed at a designed ceiling level.

  The surface position of the cast concrete or the leveling material poured onto it is called the “top level”, but this “top level” is the designed position, ie the height. There must be. In other words, in order to achieve the designed “top end level”, it is necessary to adjust the placement amount of the concrete. As shown in Patent Document 1, as a means for adjusting the placement amount. Is adopted.

In Patent Document 1, as shown in FIG. 7, “a holding portion that is continuously provided from a tongue piece is provided on a rack of a ratchet that is located at an interval through an end portion of a sliding piece. Then, a sliding piece located in a gap is connected to the rack of the ratchet via the end portion, and the tongue piece is connected to the tongue piece via the holding portion. In this "level clamping tool", the holding part is retractable, so even if the supporting material such as a reinforcing bar to which the "level clamping tool" is to be attached is large or small , It is something that can respond sufficiently.
Japanese Utility Model Publication No. 60-129453

  However, in the “level clamping device” of Patent Document 1, once the holding portion is contracted and the ratchet is once engaged with the rack, the engagement cannot be easily released, and the reinforcing bar or the like is not supported. It is considered that it cannot be easily removed from the material, and it is considered that the position adjustment of this “level clamping device” cannot be re-adjusted or reused. In particular, this type of “level member” indicating the top level is considered to have a fatal injury if “position adjustment for level indication” cannot be performed.

  Therefore, the present inventors can easily adjust the position of this kind of “level clamping device” or marker to a support material such as a reinforcing bar, and can also be reused. As a result of various investigations, the present invention has been completed.

  That is, an object of the present invention is to provide a level marker that can be easily attached and adjusted with respect to a support member such as a reinforcing bar and can be removed and reused with a simple configuration. . Another object of the present invention is to provide a level marker that can be easily adapted to different support material sizes.

In order to solve the above problems, first, the means taken by the invention according to claim 1 will be described with reference numerals used in the description of the best mode described below.
“A level marker 10 pointing to the top level 30 to be formed of concrete,
A base portion 11 disposed at a position corresponding to the top end level 30 or abutted against the disposed support member 20 and a pair of arm portions 12 integrated with the base portion 11 and sandwiching the support member 20 from both sides. And with
Level marker 10 characterized by being able to point to top level 30 when sandwiched between support members 20 by both arm portions 12 "
It is.

  That is, as shown in FIG. 1, the level marker 10 according to the present invention points to the top end level 30 to be formed of concrete and is arranged at a position corresponding to the top end level 30. The support member 20 is fitted and attached. In this case, the support member 20 may be a reinforcing bar incorporated in the formwork or may be another bar attached to the reinforcing bar.

  Therefore, as shown in FIGS. 2 to 6, the level marker 10 includes a base portion 11 that is in contact with the support member 20 and a pair of arms that are integrated with the base portion 11 and sandwich the support member 20 from both sides. 2, and as shown in FIG. 2, the support member 20 is fitted into both arm portions 12.

  This fitting operation is performed only by pressing the entire level marker 10 toward the support member 20 after the support member 20 is positioned in the slit formed between the both arm portions 12 of the level marker 10. Easy to do. When the level marker 10 is pressed, both arm portions 12 are opened to both sides according to the thickness of the support member 20 by the force, and the support member 20 completely enters both arm portions 12 so that the inner surface of the base portion 11 is This is because both arm portions 12 return to the original state when they come into contact with the support member 20 and sandwich the support member 20 from both sides.

  Of course, the support material 20 into which the level marker 10 should be fitted may be a vertical reinforcing bar, but if there is no such reinforcing bar, prepare another bar, What is necessary is just to arrange | position and use so that it may become perpendicular | vertical.

  Further, the level marker 10 has a lower end (in the case shown on the right side in FIG. 1) or an upper end (in the case shown on the left side in FIG. 1) such that the support material is pointed to the designed top level 30. Although the height position with respect to 20 must be determined, the level marker 10 fitted to the support member 20 or the bar member standing vertically is slid up and down to reach the designed top level 30. The combined position adjustment can be adjusted. This is because, in this level marker 10, each arm portion 12 is integrated with a certain degree of elasticity with respect to the base portion 11, and each arm portion 12 has a certain range with respect to the base portion 11. This is because it can be freely bent.

  Further, since the level marker 10 can be freely slid and rotated with respect to the support member 20, when removing it, the level marker 10 slides in a direction in which it is easy to work, for example, a direction in which there is no obstacle to the tripping. Alternatively, the removal operation can be easily performed by rotating.

  In other words, the level marker 10 does not cause the holding portion to contract and cause the rack and the ratchet to be fixedly engaged unlike the conventional one shown in FIG. When the support member 20 is clamped by the above, if a force greater than the clamping force of both the arm portions 12 is applied, the support member 20 can freely slide in the axial direction and rotate in the radial direction. In other words, the level marker 10 can freely change the position pointed to by itself.

  The level marker 10 may be used under the top level 30 as shown on the left side of FIG. 1, that is, embedded in concrete, or as shown on the right side of FIG. The top level 30 may be removed later without being embedded in the concrete. For this reason, it goes without saying that the level marker 10 removed later without being embedded in concrete can be reused in other constructions.

  Therefore, the level marker 10 according to the first aspect can be easily attached to the support member 20 and adjusted in position, can be removed, and can be reused.

In order to solve the above problem, the means taken by the invention according to claim 2 is the level marker 10 according to claim 1,
“Making a plurality of sets of one pair of arm portions 12 integrated”
It is.

  That is, in the level marker 10 according to the second aspect, when the pair of arm portions 12 is made into one set, as shown in FIG. 3 and FIG. The arm portion 12 is integrated with the base portion 11.

  In such a case, the number of places where the level marker 10 is attached to the support member 20 is increased by the number of sets formed by the pair of arm portions 12, and the support member for the level marker 10 is increased. The attachment position with respect to 20 will increase, and the freedom degree of the attachment operation | work will increase. That is, when the operator wants to hold the level marker 10 with one hand and engage with the support member 20, the slit between the two arm portions 12 is directed toward the support member 20 by rotating it slightly in the hand. This simplifies the mounting workability.

  Therefore, the level marker 10 according to the second aspect exhibits the same function as that of the first aspect and is easy to attach to the support member 20.

Moreover, in order to solve the said subject, the means which the invention which concerns on Claim 3 took about the level marker 10 of the said Claim 2,
“The size of the pair of arm portions 12 constituting each group is different from that of the other groups.”
It is.

  In such a case, even if the size (diameter) of the support member 20 is changed, this can be easily handled. In general, the diameter of the reinforcing bar that is the support material 20 is standardized, and there are not so many kinds, and the arm portions 12 that constitute each set are freely bent within a certain range. Even if the size (diameter) of the support member 20 changes, the level marker 10 according to the present invention can sufficiently cope with it.

  Therefore, the level marker 10 according to the third aspect exhibits the same function as that of the second aspect, and can be easily adapted to the size (thickness) of the support member 20. It has become.

Furthermore, in order to solve the said subject, the means which invention based on Claim 4 took about the level marker 10 in any one of the said Claims 1-3,
“A mounting hole 13 parallel to the axial direction of the support member 20 is provided in the base 11 or the arm 12, and the auxiliary instruction member 14 is attached to the mounting hole 13 so that the position thereof can be adjusted.”
It is.

  That is, in the level marker 10, as shown in FIG. 5, when the level marker 10 is used by being embedded at a relatively deep position (compared to the case of the left side in FIG. 1), Since the position 30 cannot be indicated, the auxiliary indicating member 14 such as a screw or a nail is employed. In other words, as shown in FIG. 4, the level marker 10 according to claim 4 is provided with a mounting hole 13 parallel to the axial direction of the support member 20 in the base portion 11 or the arm portion 12, and this mounting. As shown in FIGS. 4A and 5, the auxiliary instruction member 14 is attached to the hole 13 so that the position thereof can be adjusted.

  As a method for attaching the auxiliary instruction member 14 to the attachment hole 13 so that the position thereof can be adjusted, the simplest method is to set the attachment hole 13 as a screw hole and use the auxiliary instruction member 14 as a screw. Thereby, the protrusion amount from the level marker 10 of the said auxiliary | assistant instruction | indication member 14 can be adjusted by screwing a screw forward or screwing back with respect to the level marker 10 once attached to the support material 20. FIG. If a leaf spring is inserted into the mounting hole 13, the auxiliary indicating member 14 can be freely positioned with respect to the mounting hole 13, so that the position of the auxiliary indicating member 14 with respect to the mounting hole 13 can be adjusted. become.

  Of course, when this auxiliary indicating member 14 is adopted, as shown in FIG. 5, the head indicates the top end level 30, and a mortar, leveling material, etc. are used in accordance with the position of the head. Needless to say, it should be poured.

  Therefore, the level marker 10 according to the fourth aspect exhibits the same function as that of the first to third aspects, and moves the auxiliary instruction member 14 forward and backward with respect to the mounting hole 13 to thereby indicate the top level 30 to be indicated. This makes it easy to adjust the position.

As described above, in the present invention,
“A level marker 10 pointing to the top level 30 to be formed of concrete,
A base portion 11 disposed at a position corresponding to the top end level 30 or abutted against the disposed support member 20 and a pair of arm portions 12 integrated with the base portion 11 and sandwiching the support member 20 from both sides. And with
When the support member 20 is held between the arms 12, the top level 30 can be indicated. "
There is a main feature in the structure, and by this, the level marker 10 that can be easily attached and adjusted to the support member 20 such as a reinforcing bar, can be removed, and can be reused is provided with a simple structure. It can be done.

  Next, the invention according to each claim configured as described above will be described with respect to the level marker 10 which is the best mode shown in the drawings. In FIG. 1, the level marker 10 according to the best mode is actually used. The state is shown. As shown in FIGS. 2 to 6, the level marker 10 has a base portion 11 and an arm portion 12 and is integrally formed using, for example, a synthetic resin material.

  As shown in FIG. 2, the inner surface of the base 11 has an arc shape, and can be brought into contact with the surface of the support member 20 with a “surface”. A pair of arm portions 12 are integrated with the base portion 11, and as shown in FIG. 3, the inner surface of the arm portion 12 and the inner surface of the base portion 11 are circular shapes that are cross-sectional shapes of the support member 20. An arc surface close to can be formed.

  In addition, guide surfaces 12a are integrated with the tip portions of the arm portions 12, and these guide surfaces 12a expand both arm portions 12 when the level marker 10 is pressed against the support member 20. Thus, it is guided on the surface of the support member 20. Then, as shown in FIG. 2 or FIG. 3A, slits are formed by the tips of these guide surfaces 12a, and positioning when contacting the support member 20 due to the presence of the slits. Can be done. In other words, if the slits formed by both guide surfaces 12a are aligned with the surface of the support member 20, the level marker 10 can be aligned at a position where the level marker 10 can be reliably fitted into the support member 20. It is.

  Further, the level marker 10 of the best mode is colored with a bright color such as red or yellow, and the top level 30 can be indicated by the presence of the level marker 10. It is.

  Further, with respect to the level marker 10, as shown in FIG. 3 (a) or FIG. 6 (a) and (b), the base 11 Are integrated. Thereby, the number of slits between the arm portions 12 is increased so that a plurality of attachment positions with respect to one support member 20 are provided.

  As for the level marker 10, as clearly shown in FIG. 6B, the size of the pair of arm portions 12 constituting each group is different from that of the other groups. It is as. Thereby, even when the thickness of the support member 20 is different, the level marker 10 can be easily attached to the support member 20.

  As shown in FIG. 4, the level marker 10 may be formed such that a thick portion 11a is formed in the base portion 11 and a mounting hole 13 is provided in the thick portion 11a. . That is, in the level marker 10 provided with the mounting hole 13, as shown in FIG. 5, when the level marker 10 is embedded and used in a relatively deep position, the level marker 10 itself indicates the position of the top level 30. Therefore, an auxiliary indicating member 14 such as a screw or a nail is employed, and the auxiliary indicating member 14 is attached to the mounting hole 13 so as to be able to advance and retract.

  In other words, the level marker 10 having the mounting hole 13 and the auxiliary instruction member 14 is formed by screwing the screw forward or backward with respect to the level marker 10 once attached to the support member 20. The amount of protrusion from the 14 level markers 10 can be adjusted. Of course, if a leaf spring is inserted into the mounting hole 13, the auxiliary instruction member 14 can be freely positioned with respect to the mounting hole 13, and no screw portion is formed in the mounting hole 13 or the auxiliary instruction member 14. In addition, the position of the auxiliary indicating member 14 can be adjusted with respect to the mounting hole 13.

  Of course, when this auxiliary indicating member 14 is adopted, as shown in FIG. 5, its head indicates the top level 30, and the mortar, leveling material, etc., according to the position of this head. It goes without saying that you can pour in
