Description

A leveling device for carrying out the ground}

The present invention relates to a horizontal holding device used in the floor construction, in particular to improve the workability for horizontal maintenance at the time of floor construction by simple and precise use of the position adjustment and the height of the rail even when the rail is installed It relates to a flooring leveling device that can be easily adjusted.

In general, when the construction of the building is to make the floor flat, such as the floor or room floor of the building, when the floor construction as described above is to proceed to the level of the floor, in this case, the height of the floor Leveling device is used to maintain the overall level by adjusting the.

That is, the leveling device supports the floor together with a plurality of supporting structures in the interior of the floor while being immersed in cement or concrete supplied to the floor while horizontally adjusting the height of the floor while the floor is placed on the floor. It is a device that can be done.

Here, the conventional structure of the leveling device, as shown in Figures 1 and 2, is provided with a body frame 101 made of a triangular bar shape to have a predetermined length, the upper and lower direction on the outside of the body frame 101 A plurality of installation holes 102 are formed therethrough, and are installed perpendicular to the body frame 101 in a state where the reinforcement 103 is inserted and fixed in the installation hole 102, while the body frame 101 is Height-adjusting screws 104 are respectively installed on the left and right sides.

That is, the leveling device 105 may be a high or low body frame 101 by the rotation of the height adjustment screw 104 to the height of the floor when the floor construction, a plurality of reinforcing bars through the installation hole 102 By fixing the 103 is to be able to perform the role of a support structure to give durability to the floor.

However, the leveling device 105 is inconvenient in use because it adjusts the height by using the height adjusting screw 104, the body frame 101 accommodated on the inside of the floor by cement or concrete continuously Since it is installed to cut the cement or concrete inside the floor has the disadvantage of lowering the durability of the entire floor, it is difficult to install the reinforcement 103 in the leveling device 105, making it difficult to work during the overall floor construction There were various problems such as.

Accordingly, the present invention has been devised to solve the above problems, and by improving the workability for horizontal maintenance during floor construction by simple and precise positioning, it is possible to reduce the construction cost due to the improvement of construction properties.
