Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a support fitting that receives and supports the bottom edge of a side panel of a concrete formwork.

[Prior art] When constructing concrete parts such as walls in a concrete building, a formwork is constructed on the concrete ground and concrete is poured into the formwork, but the surface of the concrete ground is not flat. As a result, the top heights of the side panels are often uneven. Therefore, in order to prevent this, conventionally, the height of the side panel has been adjusted by stacking and sandwiching several pieces of wood such as plywood between the bottom of the side panel and the ground.

[Problems that the invention aims to solve] According to such conventional technology, the height is adjusted by stacking several plywood boards, making it difficult to make fine adjustments.
Additionally, there was a problem of extremely poor work efficiency.

[Means for solving the problem] Therefore, in the present invention, a screw rod 3 is provided protruding from the upper surface of the substrate 2 fixed to the ground 1 such as concrete, and a nut 4 for height adjustment is attached to the screw rod 3. At the same time, an L-shaped receiving plate 5 is loosely fitted to the threaded rod 3, and the receiving plate 5 is placed on the upper surface of the nut 4, and the vertical piece 5a of the receiving plate 5 and the threaded rod 3 are In between, the bottom side 6a of the side panel 6 of the concrete formwork is exposed and supported.

[Operation] By rotating the nut 4 of the screw rod 3, the receiving plate 5 moves up and down while holding the side panel 6. Therefore, by adjusting the height of the receiving plate 5 according to the unevenness of the ground 1 such as concrete, the heights of the upper surfaces of the side panels 6 can be made the same.

[Example] The substrate 2 is a rectangular flat plate made of a metal material,
The screw rod 3 is provided so as to protrude from one side of the substrate 2. Two nail holes 7, 7 are drilled in the other side of the substrate 2, and concrete nails 8 are inserted into the nail holes 7 and nailed to the ground 1 to be fixed.
Further, a through hole 3a is bored in the head of the screw rod 3.

The receiving plate 5 is made of a band plate made of metal material and has an L-shaped side surface, and the screw rod 3 is attached to the horizontal piece 5b of the receiving plate 5.
A U-shaped notch 9 having a slightly larger diameter than the diameter of the U-shaped notch 9 is formed. The U-shaped notch 9 is loosely fitted into the screw rod 3, and is placed and held on the upper surface of the nut 4 of the screw rod 3. Further, the distance between the vertical piece 5a and the screw rod 3 is made approximately equal to the thickness of the side panel 6, while the length of the horizontal piece 5b is such that it does not overlap the nail hole 7 of the board 2 when attached to the screw rod 3. The size and shape make the work of nailing concrete nails 8 easier.

Note that the side panel 6 is a plywood board.

Then, the board 2 is fixed by nailing concrete nails 8 to a predetermined position on the ground 1. On this occasion,
In order to prevent concrete from flowing out from the lower surface gap of the side panel 6, an L-shaped sealing plate 10 is provided.
is sandwiched and fixed between the board 2 and the ground 1. Then, the bottom side 6a of the side panel 6 is sandwiched and supported between the vertical piece 5a of the receiving plate 5 and the screw rod 3, and the nut 4
The height of the side panel 6 is adjusted by rotating. The side panel 6 is sandwiched between the receiving plate 5 and the screw rod 3 and is temporarily fixed, but since there is a risk of it sliding laterally, the through hole 3a in the head of the screw rod 3 is
It is desirable to drive nails 11 into the side panel 6 and fix it.

In addition, the U-shaped notch 9 of the horizontal piece 5b of the receiving plate 5 is
The notch is made to remove the substrate 2 after concrete is poured into the formwork, and the concrete nail 8 is removed and the substrate 2 is struck with a hammer or the like in the direction of the opening of the U-shaped notch 9, and then slid sideways. It can be removed by

[Effect of the invention] As described above, according to the invention, the side panel 6
It is possible to adjust the height easily and with high precision, which has the effect of contributing to improving the finishing accuracy of the finished product and shortening the construction period.
