  By the way, there are several types of deformed steel bars used for reinforcing bars for concrete foundations, and the diameters of the deformed steel bars used for the horizontal bars 121 and the vertical bars 122 vary depending on the site. That is, even if the diameter of the horizontal stripe 121 is the same, the diameters of the vertical stripes 122 intersecting with the same are not necessarily the same. For this reason, in the above-mentioned conventional top edge assisting tools 110a and 110b, the horizontal bar attachment part 113 and the vertical bar attachment part 114 or the crossed reinforcing bar abutting part according to the number of combinations of the diameter of the horizontal bar 121 and the diameter of the vertical bar 122. 115 need to be prepared with sizes corresponding to the diameters of the horizontal stripes 121 and the vertical stripes 122, respectively. If the size of the vertical bar attachment part 114 or the crossed reinforcing bar contact part 115 is larger than the diameter of the vertical bar 122, the main body part 111 moves around the extending direction of the horizontal bar 121 to which the horizontal bar attachment part 113 is attached. As a result, the top level cannot be accurately managed.

  Therefore, in the present invention, in the top level control tool attached to the crossing portion of the bar arrangement in which the horizontal and vertical bars cross each other, even if the diameters of the vertical bars are different, they move around the extending direction of the horizontal bars. An object of the present invention is to provide a top level control tool that can prevent the occurrence of the problem.

  The top level control tool of the present invention is attached to the crossing of the bar arrangement that crosses the horizontal and vertical bars in a cross, and can adjust and hold the vertical position of the bar for level setting that serves as a mark of the top level A top end level management tool having a holding portion, wherein the lower bar is open and the horizontal bar is attached to the horizontal bar from above, and the horizontal bar extends to the upper and lower positions of the horizontal bar. A vertical bar presser portion having a first surface that is a first surface that moves away from the horizontal streak as it moves away from the direction and that contacts the vertical streak and presses the vertical streak toward the horizontal streak.

  According to the top end level management tool of the present invention, when the horizontal bar attaching portion is fitted and attached to the horizontal bar at the crossing portion of the bar arrangement from above and moved in the extending direction of the horizontal bar toward the vertical bar, Regardless of the diameter of the line, the first surface of the vertical bar presser abuts the vertical line and presses the vertical line to the horizontal line side. Thereby, the top end level management tool is prevented from moving around the extending direction of the horizontal stripes by the vertical bar presser portions that contact the vertical stripes at the upper position and the lower position of the horizontal stripe attachment section.

  Here, it is desirable that the vertical bar presser has a second surface that is connected to the first surface, approaches the horizontal bar as it goes away in the extending direction of the horizontal bar, and contacts the vertical bar. Thereby, in a state where the vertical bars are in contact with the first surface and the second surface of the vertical bar pressing portion, the top end level management tool is prevented from moving in the extending direction of the vertical bars.

  Moreover, it is desirable that the top level management tool of the present invention further includes a vertical muscle abutting portion that is in contact with the horizontal muscle side of the vertical muscle at a position further lower than the vertical muscle presser portion. As a result, when the horizontal bar attaching portion is fitted and attached to the horizontal bar at the crossing part of the bar arrangement from above and moved in the extending direction of the horizontal bar toward the vertical bar, the first surface of the vertical bar presser portion becomes vertical. Abuts against the muscle, presses the longitudinal muscle to the lateral muscle side, and supports the lateral muscle side of the longitudinal muscle by contacting the longitudinal muscle abutting portion. It becomes a state, and the top level control tool is more prevented from moving around the extending direction of the transverse muscle.

  Moreover, it is desirable that the vertical bar presser portions are provided on both sides in the direction in which the horizontal bars extend with respect to the horizontal bar attachment portion. As a result, when the horizontal bar attachment part is fitted and attached to the horizontal bar at the crossing part of the bar arrangement from above and moved to the vertical bar in the extending direction of the horizontal bar, it moves to either side of the horizontal bar extending direction. Even if it is made to do, the 1st surface of a vertical bar presser part will contact a vertical line, and will come to hold down a vertical line to the horizontal line side.

  Here, it is desirable that the vertical bar presser portions provided on both sides in the extending direction of the horizontal bar have different distances from the horizontal bar attached to the horizontal bar mounting part. Thereby, according to the diameter of a vertical line, it becomes possible to select any one of the vertical line presser parts from which the distance from the horizontal line attached to a horizontal line attachment part differs, respectively, and to hold down a vertical line.

  Further, the level setting bar has a spiral groove formed in the lower part, and the holding part has a C-shaped cross section having a vertical slit, and is fitted into the groove on the inside. It is desirable to have a protrusion. As a result, when the level setting bar is rotated in the holding part, the protrusion inside the holding part is inserted into the spiral groove at the lower part of the level setting bar, so that the level setting bar moves up and down. To do. In addition, since the holding part is formed in a C-shaped cross section having a vertical slit, the C-shaped cross section is appropriately expanded and contracted when the level setting bar is rotated, and the level setting bar is smoothly rotated. Can be made.

(1) The lower part is opened and the lateral bar attachment part is fitted and attached to the lateral bar from above, and the first part that is separated from the horizontal bar as the distance from the lateral bar extends to the upper and lower positions of the horizontal bar attachment part. According to the top level control tool having a vertical muscle presser portion having a first surface that is a surface and abuts against the vertical muscle and presses the vertical muscle to the lateral muscle side, the extension of the horizontal muscle is possible regardless of the diameter of the vertical muscle. It is prevented from moving around the present direction, and the top level can be managed with high accuracy.

(2) The vertical bar presser portion is connected to the first surface, and has a second surface that comes close to the horizontal bar and comes into contact with the vertical bar as it goes away in the extending direction of the horizontal bar. In the state where the vertical bars are in contact with the first surface and the second surface, the top end level control tool is not only prevented from moving around the extending direction of the horizontal bars, but is also prevented from moving in the extending direction of the horizontal bars. Therefore, it becomes possible to manage the top level more accurately.

(3) By providing a vertical muscle abutting portion that is in contact with the horizontal muscle side of the vertical muscle at a position further lower than the vertical muscle presser portion, the vertical muscle becomes a vertical muscle presser and a vertical muscle abutting portion. As a result, the top level management tool is more prevented from moving around the extending direction of the transverse muscle, and the top level can be managed with higher accuracy.

(4) Since the vertical bar presser portions are provided on both sides of the horizontal bar extending portion with respect to the horizontal bar mounting portion, the horizontal bar mounting portion is fitted to the horizontal bar at the crossing portion of the bar arrangement from above. Thus, it can be fixed by being attached and moved to either side of the extending direction of the horizontal stripe toward the vertical stripe.

(5) Since the vertical bar presser portions provided on both sides in the extending direction of the horizontal bar have different distances from the horizontal bar attached to the horizontal bar mounting part, the vertical bar on the side according to the diameter of the vertical bar It is possible to select the presser and press down the vertical stripe.

(6) The level setting bar has a spiral groove formed in the lower part, and the holding part is formed in a C-shaped section having a vertical slit, and is fitted into the groove inside. By having the projecting portion to be rotated, the level setting bar can be rotated to move the level setting bar up and down, and the top level mark can be easily finely adjusted.

  The top end level management tool body 2 and the level setting bar 3 are made of hard resin. As the hard resin, for example, PP (polypropylene), POM (polyacetal), ABS resin, PC (polycarbonate), PA6 (polyamide), or other industrial plastic resin can be used. It is also possible to use a combination of a plurality of hard resins having good slidability.

  The level setting bar 3 is formed in a round bar shape, and the upper end 30 is used as a mark of the top end level when the leveler is poured into the base top end. Further, a scale-like diameter-expanding portion 31 that extends from the level setting bar 3 to both sides is provided at a position that is lower than the upper end of the level setting bar 3 by a predetermined distance, for example, 10 mm. The upper surface of the enlarged diameter portion 31 serves as a mark for the upper end level of the concrete to be placed before flowing the leveler.

  A spiral groove 32 is formed below the level setting bar 3. The inner diameter of the groove portion 32 is formed to be the same as the outer diameter of the upper portion of the level setting bar 3, and the strength is prevented from decreasing. Moreover, the cross-sectional shape of the groove part 32 is formed in a rectangular wave shape, and prevents damage caused by an impact or sliding. The groove 32 has a single groove and a pitch of, for example, 3.0 to 3.5 mm.

The inner diameter of the holding part 10 is set to such a size that it can be held in contact with the outer periphery of the lower part where the groove part 32 of the level setting bar 3 is formed. In addition, the upper end portion on the inner side of the holding portion 10 has a protruding portion 10 b that fits into the groove portion 32 of the level setting bar 3. The level setting bar 3 can be rotated like a screw by inserting the protrusion 10b into the groove 32, and moves up and down 3.0 to 3.5 mm per rotation.

  The horizontal stripe attachment portion 11 has a substantially cylindrical shape extending in the horizontal direction and having a C-shaped cross section with an opening 11a formed below. The inner diameter of the horizontal bar attachment portion 11 has an inner diameter corresponding to the outer diameter of the horizontal bar R1. When the opening 11a of the horizontal bar attachment portion 11 is pressed against the horizontal bar R1 from above, the horizontal bar attachment unit 11 is elastically deformed to expand the opening 11a, and the horizontal bar R1 passes through the opening 11a. Thereafter, the horizontal bar attachment portion 11 is elastically restored, so that the horizontal bar R1 is fitted to the horizontal bar attachment portion 11.

  The first surface 12a of the vertical bar presser 12 is an inclined surface that moves away from the horizontal bar R1 as it moves away from the horizontal bar R1 in the extending direction X1 of the horizontal bar R1 at a position above and below the horizontal bar attachment unit 11. In the present embodiment, the angle θ formed by the first surface 12a and the extending direction X1 of the transverse stripe R1 is set to be an acute angle. Further, the vertical bar presser 12 in the upper position is moved by pushing with a finger in the extending direction X1 of the horizontal bar R1 toward the vertical bar R2 when the top end level management tool main body 2 is attached as described later. On the back side of the upper surface of the first surface 12a, a rib 12b for reinforcement is provided.

  By the way, although the horizontal stripe R1 and the vertical stripe R2 are fastened by the wire W at the intersection, the first surface 12a of the vertical stripe presser 12 is separated into an upper position and a lower position than the horizontal stripe attachment portion 11, respectively. Therefore, it does not interfere with this wire W.

  In order to use the top level management tool 1 having the above-described configuration, first, as shown in FIG. 3, the horizontal bar attachment portion 11 of the top level management tool body 2 is viewed from above with respect to the horizontal bar R1 at the intersection of the bar arrangements.

At this time, the first surface 12a always comes into contact with the vertical stripe R2 regardless of the diameter of the vertical stripe R2, and presses the vertical stripe R2 toward the horizontal stripe R1.

  Then, as shown in FIG. 4, the level setting bar 3 is attached to the holding portion 10. When the level setting bar 3 is rotated in the holding portion 10, the protrusion 10 b inside the holding portion 10 is fitted into the lower spiral groove portion 32 and moves up and down. Thereby, it is possible to easily finely adjust the mark at the top level. Further, since the holding portion 10 is formed in a C-shaped cross section having a vertical slit 10a, when the level setting bar 3 is rotated, the cross-sectional C shape is appropriately expanded and contracted, and the level setting bar 3 Can be rotated smoothly. In addition, it is also possible to attach and use the horizontal bar attaching part 11 at the crossing part of the bar arrangement in a state where the bar 3 for level setting is previously attached to the holding part 10 of the top end level management tool main body 2.

  As described above, the top end level management tool 1 attached to the crossing portion of the bar arrangement has the vertical muscle presser portion 12 that is in contact with the vertical muscle R2 at the upper position and the lower position of the horizontal bar attachment portion 11 and the Regardless of the diameter, it is prevented from moving around the extending direction X1 of the transverse muscle R1, so that the top level can be managed with high accuracy.

  Further, since the vertical bar presser 12 of the top level management tool main body 2 is provided on both sides in the extending direction X1 of the horizontal bar R1 with respect to the horizontal bar mounting part 11, the horizontal bar mounting part 11 is crossed by the bar arrangement. When the horizontal muscle R1 is fitted and attached from above and moved toward the longitudinal muscle R2 in the extending direction X1 of the lateral muscle R1, the longitudinal muscle may be moved to either side of the extending direction X1 of the transverse muscle R1. The first surface 12a of the presser portion 12 abuts on the vertical stripe R2, and the vertical stripe R2 can be pressed toward the horizontal stripe R1. Therefore, it is possible to use it by moving it in the direction in which it is easy to work according to the dominant hand of the worker. The vertical bar presser 12 may be provided only on one side in the extending direction X1 of the horizontal bar R.
