Abstract
The present invention relates to a tie rod fixing device for fixing the tie rod for fixing to maintain the spacing of the formwork.
There is a problem in that it is very difficult and inconvenient to fix the tie rod installed between the formwork when constructing the formwork in order to solve the problem, in order to solve this, the base 10 having a screw shaft 11 on one side, The fixing plate 17 which is coupled to the inner side of the base 10 and is formed at the front for penetrating the front end of the tie rod 30 is formed therein and fixing the penetrated tie rod 30 at the inner side of the spring ( A fixed box 12 rotatably coupled to receive an elastic force by 16), a support plate 22 coupled to the screw shaft 11, and a support plate 22 to be screwed and fixed to a horizontal or vertical member A tie rod fixing device for a formwork is provided that includes a support means 20 provided with a hook shaft 25.
Therefore, according to the present invention, the fixing operation of the tie rod is very convenient and easy to shorten the air and reduce the cost, it is possible to reduce the effort, such as to accurately match the length of the tie rod to the wall length.

The present invention relates to a tie rod fixing device for formwork, more specifically, a tie rod fixing device for fixing a tie rod installed to fix the formwork is installed at a predetermined interval when constructing concrete walls, etc. It is about.
In general, in order to cure concrete such as a wall having a predetermined thickness, as shown in FIG. 1, formwork (1) (2) is installed on both sides at intervals of the thickness of the concrete wall (W), and the formwork ( 1) (2) is maintained at a constant interval by the tie rod (3) installed across the transverse direction.
The tie rod (3) has an insertion hole (3a) for inserting and fixing the fixing pin (4) from the outside of the formwork (2) on one side, the horizontal and vertical members installed on the outside of the formwork (1) on the other side After penetrating (5) and (6), it is fixed by a wedge-shaped fixing member (7), and a tool inserting portion (3b) into which a tool is inserted is formed at the tip.
And the inside of the formwork (1) is a cone member (3c) of concrete material is coupled to the appropriate position of the tie rod (3) to support the formwork (1) from the inside.
Therefore, the tie rods 3 are installed in the transverse direction in the formwork (1) (2), which are vertically set to face each other at predetermined intervals, and the tie rods (3) are supported to support the formwork (1). In the state in which the
At this time, the mixed concrete is put into both the molds (1) and (2), and if cured after a certain time, the molds (1) and (2) are dismantled and then rotated by inserting the tool into the tool insertion part (3b). By cutting a part of (3), that is, a part of the tie rod 3 to which the
However, such a conventional technique is very difficult to precisely position the formwork and the cone member when installing the tie rod during installation, and if the position is not correct according to the wall thickness when installing the cone member, the material cost is increased. Problems such as air delay and air delay were inherent.
In addition, when the nut is coupled to both ends as a means for fixing the tie rod, the cost is increased by the time required for the installation and dismantling of the formwork, and problems such as the nut is relaxed by vibration or other external pressure are inherent. .
The present invention has been invented to solve the problems of the prior art as described above, the object of the present invention is to make the combination of formwork and tie rods very convenient and easy to shorten the air and reduce the cost, It is an object of the present invention to provide a tie rod fixing device for formwork that can be easily manufactured according to the wall thickness.
Forming tie rod fixing device according to the present invention for achieving the object as described above, the base having a screw shaft on one side, and a through hole for penetrating the front end of the tie rod is coupled to the inner side of the base is formed in the front And a fixing box rotatably coupled to the inner side to fix the penetrated tie rod so as to receive elastic force by a spring, a support plate coupled to the screw shaft, and a hook coupled to the support plate and fixed to a horizontal or vertical member. A formwork tie rod fixing device is provided that includes a support means provided with a shaft.
Therefore, according to the present invention, the fixing operation of the tie rod is very convenient and easy to shorten the air and reduce the cost, it is possible to reduce the effort, such as to accurately match the length of the tie rod to the wall length.
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Figure 2 is a perspective view showing a formwork tie rod fixing device according to the present invention, Figure 3 is a partial cross-sectional view of the formwork tie rod fixing device according to the present invention.
The tie rod fixing device according to the present invention is installed on one side of the formwork provided at predetermined intervals, and is preferably installed on a horizontal or vertical member installed on the outside of the formwork.
