Description

Leveling rod for concrete pouring {Leveling rod for concrete pouring}

The present invention relates to a level rod for pouring concrete.

In general, in order to construct a reinforced concrete building, the foundation, columns, and retaining wall concrete, which are the basics of the building, are first built, and the formwork is installed between the constructed framed concrete. Concrete slabs will be built.

At this time, for the stability of the building, it is very important to construct the concrete slab so that the pouring surface is flat in all areas. In particular, in the case of the MAT foundation, it is a structure supporting the entire building, and it is a part that greatly affects the safety of the whole building. Therefore, it is important to secure the covering thickness that affects the lifespan of the building, and to secure the strength suitable for the structural design.

If the concrete slab is not flat, precision construction is difficult in the finishing construction, which is a subsequent process, and in some cases, it is necessary to chip the concrete. In addition, in order to maintain the long life of the completed building, it is necessary to maintain the flatness of the concrete slab very precisely during construction.

In this way, in order to secure the flatness when pouring concrete, a level bar engraved with a mark scale may be used. This level bar can be fixed to the floor located below the concrete slab, and the level of concrete can be adjusted by detecting the height of the concrete being poured through the scale engraved on the level bar.

However, in the case of the conventional level bar, since it is fixed to the floor located below the concrete slab, there is a problem in that it is difficult to move and install it if installed incorrectly. In addition, once installed, it is difficult to adjust the height, and different types of level rods are required depending on the type of the bottom of the slab (for example, plywood formwork, aluminum foam, discarded concrete, iron plate deck), so the manufacturing cost is low. There is a problem that rises and the work efficiency decreases.

Hereinafter, with reference to the accompanying drawings, a detailed description of the level rod for pouring concrete according to a preferred embodiment is as follows. Here, the same reference numerals are used for the same components, and repeated descriptions and detailed descriptions of well-known functions and configurations that may unnecessarily obscure the gist of the invention will be omitted.

1 is a perspective view of a level rod for pouring concrete according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of the level rod for pouring concrete of FIG. 1 . And, FIG. 3 is a view showing a state in which the level bar for pouring concrete of FIG. 1 is connected to the first rebar and the second reinforcing bar, and FIG. 4 is a view showing an installation example of the level bar for pouring the concrete of FIG. 1 .

1 to 4, the level rod 100 for pouring concrete is provided to the reinforcing bars 10 and 20 to level the concrete (C) to be poured, the support member 110 and the body part ( 120 , and a leveling member 130 .

The support member 110 is for supporting the body part 120 to be described later in a direction perpendicular to the ground, and is disposed in a direction perpendicular to the first reinforcing bar 10 and the first reinforcing bar 10 disposed in one direction. It may be provided between the second reinforcing bars 20.

The first reinforcing bar 10 and the second reinforcing bar 20 on which the support member 110 is seated may be formed to have the same diameter or different diameters, and a plurality of joint members such as wires are provided in a crossed state ( W) can be interconnected. Accordingly, the first reinforcing bar 10 and the second reinforcing bar 20 may be arranged in a “井” shape that crosses each other, and an opening having a “口” shape may be formed therein.

As such, as the opening is formed between the first reinforcing bar 10 and the second reinforcing bar 20 , a portion of the support member 110 is positioned in the opening between the first reinforcing bar 10 and the second reinforcing bar 20 . can be connected That is, it is possible to connect the intersection of the first reinforcing bar 10 and the second reinforcing bar 20 through one support member 110, which is the first reinforcing bar 10 connected only with the joint member (W). And it is possible to increase the binding force of the second reinforcing bar 20 .

The body part 120 may be provided in a vertical direction to the support member 110 , and a scale may be displayed on the outer circumferential surface. For example, the body 120 may be formed in a cylindrical shape having a hollow 120a therein, and may be formed of a material having elasticity, such as silicone, rubber, or urethane.

The scale formed on the body part 120 is for numerically indicating the height at which the concrete (C) is poured. Through this scale, the operator senses the height of the surface of the concrete (C) and cuts off the high place and the height is lowered. By replenishing concrete (C) in the lower place, it is possible to match the horizontal level of the concrete (C) to be poured.

The leveling member 130 is provided on the upper portion of the body 120 and may include a level indicator 131 protruding from the outer circumferential surface so that the pouring height of the concrete C can be grasped from the outside. The leveling member 130 may be inserted into and coupled to the hollow 120a formed in the upper portion of the body 120 . For example, the leveling member 130 and the body portion 120 may be coupled to each other through various methods such as interference fitting, screw coupling, bonding coupling, and the like.

The upper portion of the level display unit 131 is exposed to the outside after the concrete (C) is poured to indicate the location where the level rod 100 for concrete pouring is installed. Accordingly, when the concrete (C) to be poured is located at the lower part of the level display unit 131, sweep the concrete (C) through the pusher and position it up to the height of the level display unit 131, and the level of the concrete (C) is large because the amount of concrete (C) is large. When the display unit 131 is buried in the concrete (C), it is possible to keep the level by scraping the concrete (C) with a pusher up to the height of the level display unit 131 .

If the level of the concrete C is maintained in this way, a plastering operation is performed. Since the leveling member 130 is interfered with by the plastering blade during the plastering operation, the leveling member 130 can be removed before the plastering operation. For example, the leveling member 130 may be detachably formed from the body 120 to be separated, or the leveling member 130 exposed to the upper portion of the concrete C may be cut and removed. If the leveling member 130 is detachably formed from the body portion 120, the concrete C is positioned up to the height of the level indicator 131, and the leveling member 130 is poured around as the separation is made. The existing concrete C fills the upper portion of the body 120 .

A plurality of level display units 131 formed on the leveling member 130 may be provided. As described above, as a plurality of level display units 131 are provided, it may be possible to adjust the height of the concrete C to be poured. In addition, the diameter of the level indicator 131 positioned at the lower portion may be larger than the diameter of the level indicator 131 positioned at the upper part. That is, the plurality of level display units 131 may be formed to gradually increase in diameter from the upper side to the lower side. This is to prevent the blade of the cutter from interfering with the level display unit 131 located thereon when the leveling member 130 is formed to cut.

Meanwhile, the outer circumferential surface of the level display unit 131 may be formed as an inclined surface whose diameter decreases from the upper side to the lower side. In other words, the outer peripheral surface of the level indicator 131 may be formed in a tapered shape. As such, as the outer circumferential surface of the level display unit 131 is formed to be inclined, when pushing to level the level, the pushing bar can move smoothly along the inclined surface.

According to the present invention, the support member 110 may include a base part 111 , a first fixing part 112 , a second fixing part 113 , and a horizontal holding part 114 .

The base portion 111 may be provided in a flat plate shape at a portion where the first reinforcing bar 10 and the second reinforcing bar 20 intersect, and in the center, a through hole 111a through which a lower portion of the body 120 passes. ) can be formed. For example, the base part 111 may be formed in a triangular plate shape, more specifically, a plate shape having a right-angled triangular structure, and the first side A1 and the second side A2 excluding the hypotenuse are each The first fixing part 112 and the second fixing part 113 may be connected to the horizontal maintaining part 114 extending from one side.

In this way, as the base portion 111 is formed in a triangular plate shape, it is possible to reduce the weight of the support member 110 to reduce the weight of the support member 110 compared to the rectangular plate shape, and to reduce the waste of unnecessary materials to reduce the manufacturing cost. be able to

The first fixing part 112 may be formed to extend from one side of the base part 111 to surround a portion of the upper side of the first reinforcing bar 10 . For example, the first fixing part 112 may extend upwardly from the first side A1 of the base part 111, and the extended shape may be formed in a shape in which a hollow cylinder is bisected in the longitudinal direction. can

The second fixing part 113 may be disposed to be spaced apart from the base part 111 to surround a portion of the upper side of the second reinforcing bar 20 . For example, the second fixing part 113 may be connected to the second side A2 through the horizontal holding part 114 , and the extended shape may be formed in a shape in which a hollow cylinder is bisected in the longitudinal direction. .

On the other hand, assuming that the center line of the first fixing part 112 is O1 and the center line of the second fixing part 114 is O2, the center line O1 of the first fixing part 112 is the first reinforcing bar 10 . It may be formed to coincide with the central island of the first reinforcing bar 10 when coupled to, and the center line O2 of the second fixing part 114 is the second reinforcing bar 20 when coupled to the second reinforcing bar 20 . It may be formed to coincide with the central island of (see FIG. 4). In addition, the first fixing part 112 and the second fixing part 113 are formed such that the first central line O1 and the second central line O2 intersect at 90 degrees when viewed from above, so that the first fixing part 112 and the first fixing part 112 are formed to cross each other. It may be formed to have an included angle of 90 degrees between the second fixing parts 113 . That is, the first fixing part 112 and the second fixing part 113 may be arranged in a 'L' shape.

The first fixing part 112 and the second fixing part 113 are elastically deformed and may be detachably attached to the first reinforcing bar 10 and the second reinforcing bar 20 , respectively. To this end, the first fixing part 112 and the second fixing part 113 are a metal material having a high modulus of elasticity, for example, tungsten, aluminum, nickel, copper, or a metal including at least one of them. It may be formed of an alloy material. In addition, the thickness of the first fixing part 112 and the second fixing part 113 may be formed to have a size of 0.3 mm to 1.0 mm to facilitate elastic deformation while having a certain strength.

The horizontal maintaining part 114 is for maintaining the horizontality of the base part 111 , and may connect between the second fixing part 113 and the base part 111 . That is, since the second reinforcing bar 20 is located above the first reinforcing bar 10 , the first fixing part 112 and the second fixing part 113 are respectively the first and second reinforcing bars 10 and 20 ), there is a step difference between the first fixing part 112 and the second fixing part 113 so that the base part 111 may be inclined. ) by providing the horizontal holding part 114 between the base part 111 will be able to maintain the horizontal.

Specifically, the horizontal maintaining part 114 may extend upwardly from the second side A2 of the base part 111 to connect between the second fixing part 113 and the base part 111 .

Referring to FIG. 4 , the length L of the horizontal holding part 114 may be expressed as a height difference between the first center line O1 and the second center line O2 (the direction in which the body part 120 extends). In addition, the length (L) of the horizontal holding part 114 may be formed to be larger than the radius (R2) of the second reinforcing bar (20). For example, the length (L) of the horizontal holding unit 114 is the sum of the length of the radius (R1) of the first reinforcing bar 10 and the radius (R2) of the second reinforcing bar 20 (L = R1 + R2) can be provided as

This is that when the first fixing part 113 is formed in a hemispherical cross section, if the length of the horizontal holding part 114 is smaller than the radius of the second reinforcing bar 20, the horizontal holding part 114 is the first reinforcing bar ( This is because the first fixing part 112 may be inclined in the direction in which the first reinforcing bar 10 is located because it cannot cover the step difference between 10) and the second reinforcing bar 20 . And, when the first fixing part 113 is formed in a hemispherical cross section, the length of the horizontal holding part 114 is the radius R1 of the first reinforcing bar 10 and the radius R2 of the second reinforcing bar 20 . ) is greater than the sum of the lengths (L = R1 + R2), the length of the horizontal holding part 114 becomes greater than the step difference between the first reinforcing bar 10 and the second reinforcing bar 20, so the second fixing part 113 is lifted from the second reinforcing bar 20 so that the second fixing part 113 may be inclined in the direction in which the second reinforcing bar 20 is located.

As described above, the level rod 100 for pouring concrete is a first reinforcing bar 10 and a second reinforcing bar ( 20), the binding force of the first reinforcing bar 10 and the second reinforcing bar 20, which were only connected by the joint member W, can be increased. Accordingly, even if the joint member W is loosened or broken during the pouring operation, the first reinforcing bar 10 and the second reinforcing bar 20 may be firmly bound by the supporting member 110 .

In addition, as the level bar 100 for pouring concrete is stably fixed to the first reinforcing bar 10 and the second reinforcing bar 20 , even if the pouring hose of the concrete C rubs the level bar 100 , the level bar (100) can be prevented from being separated from the reinforcing bars, work efficiency can be increased.

In addition, since the level bar 100 for pouring concrete is not fixed to the lower floor of the concrete slab as in the prior art, but is fixed to the first reinforcing bar 10 and the second reinforcing bar 20, regardless of the type of the lower floor of the concrete slab It has the advantage of being able to install.

In addition, since the first fixing part 112 and the second fixing part 113 of the support member 110 are detachably formed from the first reinforcing bar 10 and the second reinforcing bar 20, respectively, the level bar 100 ) has the advantage of being easy to move and install when installed incorrectly.

The height adjustment part 121 may be formed to protrude downward of the body part 120 , and a screw thread may be formed on an outer circumferential surface of the body part 120 . In addition, the height adjustment part 121 may be inserted into the through hole 111a of the base part 111 . At this time, the diameter of the through hole 111a is formed to be larger than the diameter of the height adjusting part 121 and smaller than the diameter of the body part 120 , so that the lower end of the body part 120 is supported by the base part 111 . can be formed as much as possible.

The nut part 122 may be coupled to the thread of the height adjusting part 121 passing through the through hole 111a in the lower part of the base part 111 . Accordingly, when the height adjusting unit 121 or the nut unit 122 is rotated, the length of the body unit 120 can be increased or decreased, so that the pouring height of the concrete C can be increased or decreased as desired.

For example, when the nut part 122 is fixed to the lower surface of the base part 111, the length of the body part 120 can be increased or decreased by rotating the height adjustment part 121, and the nut part 122 is When not fixed to the base portion 111, by interposing a height adjustment plate having a certain thickness between the base portion 111 and the nut portion 122, and then coupling the height adjustment portion 121 and the nut portion 122 to each other The length of the body part 120 may be increased or decreased.
