Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a floor concrete level adjuster.

[0002]

[Prior art]

 Conventionally, in the construction of a reinforced concrete building, it has been necessary to finish the slab surface at a predetermined position to a horizontal surface when placing concrete.

[0005] Before casting, reinforcing bars are arranged on the upper surface of the floor formwork, and measured at a key point such as an extension column or a wall bar with a level device or the like, and a mark or slab is formed. A concrete mass of a predetermined height was placed on the surface, or a jig of a predetermined height was fixed with nails and protruded.

[0004] However, at the time of placing concrete, an operator sometimes hardens the concrete or accidentally kicks out a jig having a predetermined height.

[0005]

[Problems to be solved by the invention]

[Embodiment of the invention]

 One embodiment of the present invention will be described with reference to the accompanying drawings. It comprises a main body (1) for driving a floor form (X) and a level display plate (2) capable of recognizing and adjusting a level surface. In the level adjuster, the main body (1) is provided with a horizontal holding portion (1a) having an expanding wing at a tip portion, and an insertion nail (1b) is provided at the center of the holding portion. 1) A locking arm (3) is provided near the center in the length direction for locking to the reinforcing bar, and a male screw (1c) is provided at an end of the main body (1). A folding groove (1d) is provided at the end of the main body, and the level display plate (2) comprises a cylindrical portion (2a) and a flange portion (2b), and the inner wall of the cylindrical portion has A female screw to be screwed with a male screw at the upper end of the main body (1) is provided, and a cuttable first arm portion is provided on the flange portion (2b). 2c) and a second arm (2d), a display part (2e) protruding upward on the first arm (2c), and a rotating hole (2f) on the second arm (2d). It is composed of a floor concrete level adjuster characterized by the installation of a floor.

Further, the main body (1) is characterized in that a plurality of recesses (2g) are provided in the axial direction on the entire circumference, and are formed in a cylindrical shape for reinforcement in the middle.

Next, the method of using the present invention will be described with reference to the drawings. Before the concrete is cast into the floor frame material (X), the insertion nail (1b) of the main body (1) is driven and the locking arm (1) is engaged. In 3), a level display plate (2) is screwed to the main body (1) and fixed to one of the horizontally intersecting reinforcing bars assembled in the floor form material (X). The height of the first arm (2c) is adjusted so that the display part (2e) protruding upward is erected, and the position is cautioned and called.

[0010] In addition, the display portion (2e) protruding above the first arm portion (2c) is pinched, and the level display plate (2) is rotated to adjust the display portion to a predetermined height. A rotary hole (2f) is provided in the two-arm part (2d), and the tip of a writing instrument such as a pencil or a ballpoint pen is inserted into the rotary hole (2f) and rotated to set the level display plate (2) to a predetermined position. It is adjusted to the height position.

[0011] Further, the display portion (2e) of the level display plate (2) is erected, concrete is cast, and after fixing, the level display plate (2) and the main body (1) are left as they are. The second arm portion (2d) is removed from the level display plate (2) by holding the display portion (2e).

[0012]

[Effect of the invention]

 According to the present invention, the main body (1) is provided with a horizontal holding portion (1a) having an expanded wing at a tip portion, and an insertion nail (1b) provided at the center of the holding portion. The nail (1b) is not driven into the floor formwork (X) for a certain length or more, the depth of the driving is constant, and the horizontal holding part (1a) having the expanding wings is used to secure the nail. The body (1) can be driven perpendicularly to the floor form material (X) and can be maintained vertically. Further, the body (1) can be connected to the assembling rebar near the center in the longitudinal direction. A lock arm (3) is provided, which can be fixed firmly even before installation of concrete, and a male screw (1c) is provided at the end of the main body (1). A folding groove (1d) is provided at the end of the main body (1), and the main body (1) is inserted from the folding groove (1d). You can adjust the length of the body by folding.

[0013] Furthermore, a female screw provided on the cylindrical portion (2a) of the level display plate (2) and a male screw at an end portion of the main body are screwed together, and the second arm of the level display plate (2) is screwed. Finely adjust the level display plate (2) to a predetermined height easily by inserting the tip of a writing instrument such as a pencil or ballpoint pen into the rotating hole (2f) of the section (2d) and rotating it. It has extremely beneficial effects such as accurate leveling.
