Description

[Detailed Description of the Invention] Γ Industrial Application Field The present invention relates to a concrete form holder that holds a concrete form during concrete pouring work.

Γ Problems to be solved by conventional techniques and ideas In order to hold the concrete formwork during concrete pouring work, in the past, one end of a large number of square timbers was generally nailed to the concrete formwork.
The other end was fixed to the ground next to the concrete formwork.

However, in such conventional methods, there are problems in that it is not only difficult to accurately set and hold the concrete formwork in a predetermined position, but also that it takes a great deal of time and effort to attach and remove the square timbers. Ta.

In order to solve such problems, this invention
The present invention provides a new concrete form holder.

Γ Means for Solving the Problem The concrete formwork holder of the present invention has adjustable spacing between each vertical part of the substantially shaped frame body, and a formwork holding piece is attached to each vertical part in a height-adjustable manner. It is installed. That is, the horizontal part 2a of another substantially-shaped member 2 is slidably fitted into the hollow horizontal part 1a of the substantially-shaped member 1, and the screw 3 is inserted to penetrate the horizontal part 1a from the inside out.
allows both the horizontal parts 1a and 2a to be fixed to each other, and the vertical part 1b of the substantially-shaped member 1
As an example, square-shaped formwork holding pieces 4 and 5 are attached to the vertical part 2b of the substantially-shaped member 2 so as to be adjustable in height, and each formwork holding piece 4 and 5 is attached with screws 6 and 7. It can be fixed to each vertical part 1b, 2b, respectively. The screw 3 is a chisel screw, for example, and is screwed into an internal thread 8 provided on the horizontal part 1a of the substantially-shaped member 1, so that the tip can come into contact with the horizontal part 2a of the substantially-shaped member 2 (Fig. 2). ). When attaching each formwork holding piece 4, 5 to the vertical parts 1b, 2b, each formwork holding piece 4, 5 is attached as an example.
are fixed to support frames 9 and 10, and the support frames are slidably fitted into the respective vertical portions 1b and 2b. Further, the screws 6 and 7 are, for example, chimney screws that penetrate one side wall of each of the support frames 9 and 10 in the horizontal direction. That is, each of the two-way screws is provided in the support frames 9, 10 and screwed into the female screws 11, 12 so that the tips of the two-way screws can come into contact with the vertical portions 1b, 2b (FIG. 3). Reference numeral 13 denotes one or more nail holes drilled in the formwork holding pieces 4, 5 (Fig. 3), so that the formwork holding pieces 4, 5 can be fixed to the concrete formwork with nails as necessary. (Figure 4). Reference numeral 14 denotes leg plates provided at the lower ends of the vertical parts 1b and 2b in order to provide independence to the concrete form holder. The leg plate 14 may be detachable from the vertical lower end.

Γ Effect When using the concrete form holder of the present invention, the concrete forms 21 and 22 are laid down at predetermined positions on the leveled concrete 20, and each vertical part 1
The concrete form holder, whose spacing between b and 2b has been adjusted according to the concrete form, is leveled at a predetermined interval and made to stand on its own at a predetermined position on the concrete 20, and the concrete formworks 21 and 22 are raised, and each vertical section is The formwork holding pieces 4, 5 of 1b, 2b may be fixed to the respective vertical portions 1b, 2b with screws 6, 7 while in contact with the upper ends of the concrete formworks 21, 22. In such cases, concrete formwork 21, 22
is fixed in a predetermined state. In this state, concrete 23 is poured between the concrete forms 21 and 22 (Fig. 4).

When removing the concrete formwork 21, 22, loosen the screws 3, 6, 7 and remove the vertical parts 1b, 2.
The formwork holding pieces 4 and 5 of b are attached to the concrete formwork 21,
22 and open the concrete form holder outward.

Γ Effect of the invention According to the invention, concrete formwork can be accurately set and held at a predetermined position. Also,
The concrete form holder of the present invention can be attached to and removed from the concrete form very easily and in a short time, and can be installed and removed even by unskilled persons including women. Furthermore, the concrete form holder of the present invention can be used for various concrete forms because the distance between the vertical parts and the height of each form holding piece can be freely adjusted.
