Description

[0001] The present invention relates to a height indication mechanism for a concrete pouring apparatus,

More particularly, the present invention relates to a height indicator for pouring concrete, which can accurately estimate the thickness of concrete when pouring concrete during construction of a slab, will be.

When the concrete structure is constructed, a mold is installed in the bottom slab, and reinforcing bars are installed. After that, concrete mortar is poured and cured to build the floor of the building.

When building a slab, its thickness can be determined according to the design criteria of the building. The factory will be designed to be thicker and the slab thickness will be designed to be relatively thin for residential apartments. The contractor will have to adjust the thickness of the slab according to the site design criteria.

A height indicator is needed to make the height more precise and accurate, and to make it easy for the operator to use.

As related related art, Korean Patent Application No. 10-2006-0081394 is available. A recessed portion having a bottom surface and a side surface opened to allow the reinforcing bars to be inserted in the lower side so as to be able to pass sideways is formed, and a hook portion having elasticity is formed on the lower side of the recessed portion, and one or more A display device comprising a display body including a main body provided with a groove, a screw shaft capable of receiving a tip at a groove of the main body, and a handle having a reference display portion whose one end is extended laterally, Lt; / RTI > Therefore, it is possible to easily install the pouring height indicator in order to keep the concrete pouring surface constant due to the concrete pouring irrespective of the straight reinforced concrete structure or the crosshole reinforcing structure.

However, this structure is complicated and the product should be buried in the concrete mortar after pouring, so it should be used only once. So we have to suffer economic losses. Also, there is a problem that the setting time is prolonged because the setting operation is not easy during the height setting process.

Korean Patent Application No. 10-2009-0055549 discloses a reference device for indicating a height of a concrete pouring structure. The reference device includes a cylindrical reinforcing bar coupling portion having a lower side opened in the longitudinal direction so as to be fixed to a reinforcing bar, And a rotation preventing portion provided in the longitudinal direction so as to be supported under the upper reinforcing bar at the upper portion of the reinforcing bar coupling portion so as to prevent the reinforcing bar coupling portion from being rotated by the striking member, To provide a reference standard. The present prior art provides a concrete placement height reference device which facilitates the work of fitting a reinforcing bar joint portion into a reinforcing bar while reducing the possibility of breakage even if a worker treads over the portion where the concrete is laid, This is not related to the purpose of making fine adjustments.

According to the above construction, a height indicating mechanism for pouring concrete is provided so that the height of the concrete mortar can be quickly and constantly adjusted when the concrete mortar is installed to install the slab at the time of construction.

More specifically, at least the leveling rod and the leveling rod mounting means can be pulled up after concrete pouring and reused.

In addition, since the indicator can be moved up and down along the level bar, the height of the indicator can be easily adjusted finely, and a height indication mechanism for concrete pouring can be provided which is simple in structure and free from by-products in use.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings attached hereto. First, one embodiment of the present invention will be described with reference to Figs. Other drawings are to be quoted where necessary.

The height indication mechanism for pouring concrete according to the present invention includes a level rod 30 of a straight line type and a level rod mounting means for installing the level rod 30 so as to be perpendicular to the floor surface 1. [ The indicator bar 33 is provided on the level bar 30 so as to be conspicuous. The level bar 30 is shaped like a wire, and the indicator hole 33 is provided with an intermediate fitting groove so that it can be inserted into the level bar 30. The operator can hold the indicator 33 and move the indicator 30 in the vertical direction K along the level bar 30. [

At this time, it is preferable that the level bar 30 is made of a steel wire or a plastic material so as to maintain rigidity without being easily bent.

The indicator (33) is made of synthetic resin in the form of a disc, for example, such as yellow or white, which is well visible in contrast to concrete (M). The indicator 33 may be painted with fluorescent paint to improve nighttime discrimination power. The height H between the display unit 33 and the bottom surface 1 is a criterion for placing the concrete M therein.

The indicator fixing means is means for fixing the indicator 33 to a specific position of the straight portion 31 of the level bar 30. According to the present embodiment, the display unit fixing means can be the stoppers 34 and 35 that can elastically cover the level bar 30.

The stoppers 34 and 35 are made of a ring-shaped elastic material and positioned at the upper and lower portions of the display 33 so that the display 33 can not flow beyond the stoppers 34 and 35. Of course, the stoppers 34 and 35 can easily move in the direction of the arrow K 'along the level bar 30. [ However, the stoppers 34 and 35 do not flow down or flow by themselves or by a small force due to the frictional force depending on the material characteristics. When the stoppers 34 and 35 are brought into close contact with the upper and lower surfaces of the display 33, the display 33 is fixed in place.

According to the embodiment of the present invention, the lower end portion of the level bar 30 is formed as a spring 32. The spring 32 is in the form of a tension coil spring. This ensures that the level bar 30 is restored to its original position by elasticity without being broken even when it is hit from the side. The center of the spring 32 is provided with a hole through which a screw or the like can be inserted and fixed. By using this hole, the level bar 30 can be erected.

On the other hand, the upper end of the level bar 30 may be provided with a ring 36 having a "C" shape or an "O" shape. This is to make it easy to insert the level bar 30 by inserting a hand or a tool when the concrete rod is poured out as shown in FIG. There is also a risk of injury if the pointed object is upside down on the floor, but the collar (36) also prevents this danger. The operator can easily pull out the level bar 30 by inserting a finger or a reinforcing bar into the loop, and the removed level bar 30 is reused.

Hereinafter, the level rod mounting means according to the embodiment of the present invention will be described. The level bar mounting means according to the present embodiment includes a magnet mounting portion 20 fixedly installed at the lower end of the level bar 30 at right angles.

The magnet mounting portion 20 is fixed to the bottom surface or bottom surface of the metal by magnetic force so that the leveling rod 30 is attached to the bottom plate 10 made of metal. The bottom plate 10 may be provided with a nail hole 12 through which the nail 11 can be inserted.

At this time, the bottom plate 10 may be made of magnetic material having magnetic force as well as metal. In the case where the bottom plate 10 is made of a magnetic material as described above, there is an effect that the level bar 30 can be easily installed regardless of where the bottom plate 10 is installed.

If the formwork is made of concrete, it will be possible to install it directly without any additional parts. However, in the case of being made of wood or the like, it is possible to fix the metal plate 10 first, and then install a concrete height-indicating mechanism thereon.
