Abstract

The present invention relates to a concrete placing height reference, in particular, it is composed of the reinforcing bar and the display unit, and formed by connecting to each other by forming a female screw and a male screw in the reinforcing bar and the display bar, such a reference bar when the concrete There was a drawback that the male screw portion formed on the display portion was broken relatively easily. Accordingly, the present invention provides a concrete placing height reference by forming a male screw portion formed on the display portion with an iron spring and combining the placing height display plate with the upper portion of the iron spring, thereby providing a concrete placing height reference with less fear of breakage.

Description

Concrete placing leveler {Concrete placing leveler}

The present invention relates to a concrete placing height reference, and more particularly, to a concrete placing height reference consisting of a reinforcing bar portion and a display portion and by forming a female screw portion and a male screw portion, respectively.

      Standards for horizontal casting of concrete are commonly known. By the way, this invention relates especially to the improvement of the invention of the pre-patent patent of patent 8834141, the patent 746617, and the patent 794618.

      The reference machine of the above invention is composed of a rebar coupling part and a display part, and a female thread part and a male thread part are formed in the rebar coupling part and the display part, respectively. After adjusting the height of the display unit, the reference unit is connected to the reinforcing bar, and the concrete is configured to pour to the upper end of the display unit.

  By the way, in the case of concrete pouring work, the worker walks on the reinforcing steel bars and even carries a heavy wagon, so that the screw part formed on the display portion of the reference machine is relatively easily broken.

Accordingly, the present invention aims to solve the problem of providing a standard that is not damaged even when walking on a reinforced rebar or even carrying a wagon.

In order to solve the above problems, consisting of a reinforcing bar portion and the display portion, and formed by the female screw portion and the male screw portion, respectively, the reinforcing bar portion and the display portion, the present invention is to form a male screw portion to be formed in the display portion made of steel spring and steel spring Provides a concrete placing height reference by combining the placing height display board with the upper part of the height standard.

Furthermore, the present invention provides a height reference that is easy to remove the display part after pouring concrete, and to facilitate the operation of connecting the screw portion of the display part to the reinforcing bar.

The present invention has the effect that the male screw portion formed in the display portion is made of an iron spring so that there is no fear that the male screw portion of the display portion will be damaged at all.

In addition, the present invention is very easy to remove the display portion after pouring concrete, the effect of being able to easily turn the male screw portion of the display even when turning the male screw portion of the display portion to adjust the height of the display portion installed in the reinforcing bar portion There is.

Consists of the reinforcing bar (1) and the display section (2), and to form the female screw section 11 and the male screw section on the rebar coupling section (1) and the display section (2), respectively, to screw the female screw section 11 and the male screw section WHEREIN: This invention provides the reference | standard set which consists of the steel spring 21 with the external thread part provided in the display part 2. As shown in FIG.

In order to be able to easily couple the pouring height display plate 22 to the spring 21, the pouring height display panel 22 indicating the concrete pouring height is coupled to the male threaded portion that is the spring 21. In order to facilitate the removal of the pouring height display panel 22 after the pouring of the present invention, the present invention is provided by installing two outward elastic bars 31 and 32 opposed to the bottom of the pouring height display panel 22. Provide a baseline. Each outward elastic bar (31, 32) is preferably provided with a convex jaw (4) outwardly at the lower end so that the convex jaw (4) is fitted into the inner recess of the spring 21 to maintain the position. .

In order to couple the spring 21 to the female threaded portion 11 of the reinforcing bar 1 and to adjust the installation height of the placing height display panel 22, the spring 21 should be rotated. Provided is a reference that allows for easy rotation. That is, in the present invention, when the outward elastic bars 31 and 32 coupled to the spring 21 are coupled to the spring 21, the outward elastic bars 31 and 32 are relatively inclined in the inner and outer directions of the spring 21. Although easy, the outward elastic bar (31, 32) is provided with a reference base that is provided with a companion rotary coupling structure to make the spring 21 also rotates together.

An embodiment of such a combined rotational coupling structure is shown in FIGS. 2 and 3. That is, in the accompanying rotary coupling structure, the upper end of the spring 21 is bent to form the locking jaw 5, so that the locking jaw 5 is inserted into the space between the two outward elastic bars 31 and 32, and thus the outward elastic bar. When the 31 and 32 rotate, the spring 21 may be configured to rotate. In addition, the upper inlet portion of the spring 21 may be formed in an elongated shape such as an elliptical shape and have a cross section of the outward elastic bars 31 and 32. By forming an elongated shape, the outward elastic bars 31 and 32 are inserted into the upper inlet of the spring 21 so that the outward elastic bars 31 and 32 and the spring 21 are rotated together. have.

The present invention further goes beyond this, and provides the invention using the invention of the present inventors patent application No. 10-2008-0030775 to the present invention as described above. In other words, the above-described invention is formed by forming the opening 6 in the longitudinal direction in the female screw portion of the reinforcing bar portion, and provides a reference group formed by forming the opening 6 in the female screw portion of the present invention as described above. do.

In addition, the present invention further provides a reference device provided with a locking device for suppressing the opening of the opening 6 above. In addition, the present invention provides a reference to the locking device to form a locking jaw strap 61 in one wing of the opening 6 and the locking groove 62 in the other wing as shown in the accompanying drawings.

1 is a perspective view of a concrete placing height reference of the present invention.

Figure 2 is a perspective view and a plan view showing a spring of the display unit of the present invention.

Figure 3 is an explanatory view showing an embodiment of a combined rotation coupling structure of the display unit of the present invention.
