(57) [Abstract] [Purpose] A concrete crown end that can be easily adjusted by rotating the joint 2C so that the supporting height of the field edge material can be easily adjusted according to the desired thickness of the concrete 4. It is intended to provide a ruler. [Structure] The supporting leg 2 is composed of a supporting leg 2 and a field edge member 3, and the supporting leg 2 has a right screw rod 2B planted in the center of the upper surface of a flat rectangular base 2A having nail holes 2A1 at its four corners, and a screw on the right screw rod 2B. It is composed of a combined joint 2C, a left screw rod 2D screwed to the joint 2C, and an upward U-shaped field edge member receiver 2E fixed to the upper end of the left screw rod 2D. Is configured to be fitted into the field edge member receiver 2E from above.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a concrete crown leveling ruler having a novel structure.

[0002]

[Prior Art]

 Conventionally, this kind of thing is as follows. 1) Reinforcing bars are planted, and tape for marking is wound around them to make points. 2) Use a pier. 3) Use radar level.

[0003]

[Problems to be solved by the device]

 The conventional techniques described above have the following problems. 1) With the method of winding the tape to the point, the tape is hidden by the concrete that is placed, and the desired height cannot be known. 2) The support height cannot be adjusted by the method of using the pier. 3) An error is likely to occur in the method using the radar level.

The present application has been made in view of such problems of the conventional technology, and an object of the present application is to provide a device capable of solving the above problems.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is as follows. That is, the one of the present application is composed of a support leg 2 and a field edge member 3. The support leg 2 has a right-handed screw rod 2B planted in the center of the upper surface of a flat rectangular base 2A having nail holes 2A1 at four corners, and this right-handed screw. Consists of a joint 2C screwed to the rod 2B, a left screw rod 2D screwed to the joint 2C, and an upward U-shaped field edge member receiver 2E fixed to the upper end of the left screw rod 2D. The field edge material 3 fitted into the field edge material receiver 2E from the upper surface is a concrete top end ruler composed of an upward U-shaped template material 3A. In this case, the edge material 3 can be made into a square shape.

[0006]

【Example】

 Examples will be described with reference to the drawings. Reference numeral 1 is a concrete top edge ruler of the present invention, which is composed of a supporting leg 2 and a field edge material 3. The supporting leg 2 is a right-handed screw rod 2B planted in the center of the upper surface of a flat rectangular base 2A having nail holes 2A1 at the four corners, a joint 2C screwed to the right-hand screw rod 2B, and screwed to the joint 2C. It is composed of a left-handed threaded rod 2D and an upward U-shaped field edge member receiver 2E fixed to the upper end of the left-handed threaded rod 2D.

The field material 3 is composed of an upward U-shaped mold member 3A and a connecting portion 3B. The mold member 3A is composed of a bottom portion 3A2 having a reinforcing ridge 3A1 and left and right side walls 3A3 which are erected upright on both edges of the bottom portion. The connecting portion 3B is composed of a mold material having substantially the same cross section as the mold material 3A. 3B1 is a stopper. This field material 3 is a known material. Further, the field material 3 may be a square-shaped field material 3C. Then, the field edge material is fitted from the upper surface to the field edge material receiver 2E of the concrete top end leveling ruler 1 arranged in a straight line.

The operation will be described. 1) Rotate the joint 2C to adjust the height of the field edge receiver 2E according to the desired thickness of the concrete 4. 2) The base 2A is fixed with nails using the nail holes 2A1. 3) Set the intervals between the concrete top and bottom rulers within a 1500 mm pitch. 4) Set the edge materials in the vertical direction and bind them together with the binding wires. 5) Fix the height to 10-0 with level and water thread. 6) After this, concrete 4 is poured. In the figure, 5 is a reinforcing bar.

[0009]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. 1) Since the joint 2C can be expanded and contracted by the rotation, it is possible to easily adjust the support height of the field edge material according to the desired thickness of the concrete 4. 2) It can also be used for inclined surfaces, especially for water gradients. 3) It is possible to reduce costs because there is little slippage, repair, and dents in concrete. 4) Even an amateur can easily install it. 5) It is also possible to prevent cracking of the slab.
