Abstract

PURPOSE:To obtain a level support which can be fixed easily to the structural steel at a construction site. CONSTITUTION:A supporting frame 1 is provided, on one side thereof, with powerful magnet body 4 for generating magnetic force or interrupting generation thereof from a magnetic face 3 based on the function of an operational switch 2 and, on the other side thereof, with a rod 7 moving rotationally in the horizontal direction through a shaft part 6 having a knob part 5 for rotating or stopping the rotation of the rod 7.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spirit level support suitable for mounting a spirit level for measuring the height of a floor or the like at a construction site such as steel frame construction.

[0002]

2. Description of the Related Art It is known that a wooden frame has been conventionally assembled to attach a spirit level at a construction site such as steel frame construction.

[0003]

However, there is a risk that the wooden frame cannot be assembled easily and easily, and that it requires skill to perform the assembly at a low cost and quickly.

The present invention solves the above-mentioned problems, and an object of the present invention is to provide a convenient level support that can be easily attached to a steel frame at a construction site.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention is to perform generation and non-generation of magnetic force on a magnetic surface 3 on one side of a support frame 1 based on opening / closing of an operation switch 2. Is provided with a strong magnet body 4 that can be moved, and on the other hand, a rotation rod 7 that is horizontally rotated via a shaft portion 6 having an operation knob portion 5 that can perform stop and rotation operations, Further, a level mounting plate 9 is attached to the tip of the rotating rod 7.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIGS. 1 to 7 show a first embodiment in which one side of a support frame 1 is made magnetic by opening and closing an operation switch 2. Strong magnets 4 and 4 capable of generating and not generating the magnetic force of the surface 3 are provided on the upper and lower sides, and on the other hand, a shaft portion 6 having an operation knob portion 5 capable of performing stop and rotation operations. A rotary rod 7 that pivots in the horizontal direction is provided through the rotary lever 7, and the tip end of the rotary rod 7 is pivoted in the horizontal direction via an operation knob shaft portion 8 that can be stopped and rotated. At the same time, a level mounting plate 9 having a mounting shaft 11 capable of screwing the level 10 into the mounting screw 12 of the level 10 is mounted, and the rotary rod 7 is connected to the shaft portion 6 downward. The lower tilt reinforcing rod 13 provided is attached, and further, as shown in FIGS. 6 and 7, the surface of the steel frame 14 It is intended to attach the magnetic surface 3,3.

8 to 11 show the second embodiment, in which the magnetic force of the magnetic surface 3 is generated or not generated on one side of the support frame 1 based on the opening and closing of the operation switch 2. On the other hand, there are provided strong magnet bodies 4 and 4 capable of moving, and on the other hand, a turning rod which moves in a horizontal direction through a shaft portion 6 having an operation knob portion 5 capable of performing stop and rotation operations. 7 is provided, and further, at the tip of the rotating rod 7, is horizontally rotated through an operation knob shaft portion 8 capable of performing stop and rotation operations, and is screwed into a mounting screw 12 of a level 10. Level 1
A level mounting plate 9 having a mounting shaft 11 to which 0 can be mounted is mounted, and an upper inclined reinforcing rod 15 connected to the shaft portion 6 is mounted on the rotating rod 7 upward, and further shown in FIG. As described above, the magnetic surfaces 3 are attached to the surface of the steel frame 14.

When it is close to the floor surface 16, it is possible to lower the mounting position of the level by using the one shown in the second embodiment as shown in FIG. Fifteen is an obstacle.

[0009]

The present invention is constructed as described above, and one of the support frames 1 is a strong magnet body capable of generating or not generating the magnetic force of the magnetic surface 3 based on the opening / closing of the operation switch 2. 4 is provided, and on the other hand, there is provided a rotating rod 7 which is pivotally moved in the horizontal direction through a shaft portion 6 having an operation knob portion 5 capable of performing stop and rotation operations, and further, a rotating rod 7 Since the electronic level mounting plate 9 is attached to the tip of the above, when attaching the electronic level 10, the magnetic surface 3 is magnetically attached to the steel frame 14 as shown in FIGS. 6, 7, and 11. .

By the way, since the operation switch 2 is provided on the strong magnet body 4 so that the magnetic force can be generated or not generated, the magnet body 4 can be easily attached and detached from the steel frame 14.

Further, although the level 10 can be mounted on the leveling plate 9 to carry out the measurement, a complicated means such as a wooden frame is not required to mount the leveling 10. A person who does not need a person, etc. can easily use the level 10
Can be attached.

Further, the rotary rod 7 having the level mounting plate 9 attached thereto is leveled through a shaft portion 6 having an operation knob portion 5 capable of stopping and rotating the support frame body 1. Since the level 10 is pivotally moved in the direction, the level 10 can be easily moved in the horizontal direction and the survey can be easily performed.

Further, the structure is simple, the manufacture is easy, and it can be provided at a low cost, and has various industrial effects.
