It should be understood that various equivalents and variations may exist.

Hereinafter, the present invention will be described in more detail with reference to the attached FIGS. 1 to 5 showing an embodiment of the present invention.

As shown in Figures 1 and 2, the form support post according to the present invention has a support part (1a) for ground support at the bottom, a cylindrical shape perpendicular to the support part, and a male thread part (1b) on the outer circumference. A lower pipe (1) is formed, and a female threaded portion (2a) is formed on the inner diameter to be fastened to the male threaded portion of the lower pipe (1), and a hollow shaft portion (2b) and a support ledge (2c) are formed around the upper outer circumference. A support member (2) with a plurality of lever parts (2d) protruding from the lower outer circumference, and a lower end inserted into and supported by the shaft part (2b) of the support member (2) coupled to the lower pipe (1), In the form support post (10) consisting of an upper pipe (3) provided with a support portion (3a) for supporting the form,

A support member (4) for seating and coupling to the support member (2) is coupled to the lower inner diameter of the upper pipe (3).

As shown in the attached FIG. 3, the support member 4 is cylindrical and has a support 2c of the support member 2 at its lower end so as to be seated and coupled to the support 2c of the support member 2. It has a flange portion (4a) in close contact with the flange portion (4a), and a shaft insertion portion (4b) that is inserted into the lower inner diameter of the upper pipe (3) is formed in the center of the flange portion (4a).

The support member 4 of this shape is coupled and supported with the shaft portion 2b of the support member 2, and the upper part of the flange portion 4a includes a seating groove for seating the lower end of the upper pipe 3. 4c) is formed, and a screw fastening hole (4d) is formed on the seating groove (4c), and this screw fastening hole (4d) is fastened to the lower end of the upper pipe (3) as a fastening screw (S). .

The outer diameter of the support 2c of the support member 2 is inclined so that the upper part is narrow and the lower part is wide. This means that the outer diameter of the flange portion 4a of the support member 4, which is seated on the support member 2c, is formed to have a larger diameter than the upper diameter of the support member 2c of the support member 2. This is to have a step that facilitates separation of the support member 2 from the upper pipe 3.

Meanwhile, the upper pipe 3 is an aluminum steel pipe, and in its outer longitudinal direction, protrusions 3b and angled recesses 3c are formed alternately by a rolling method, and a support is provided at the bottom of the protrusions 3b. A screw fastening groove (3b-1) is formed for coupling with the member (4).

The concave portion 3c of the upper pipe 3 is angled in the upper pipe 3, and its shape along with the protrusion 3b is erected vertically to increase rigidity against bending as it is used to support the form. It was done.

The operation according to the use of the form support post of the present invention configured as described above is described as follows.

As is well known, the post 10 used to support the form is supported at multiple points on the lower part of the form for forming the slab of the building to support the load resulting from the formation of the structure. The post according to the present invention is largely composed of the lower pipe ( It is divided into 1) and upper pipe (3), so it can be transported to the site where the post is to be installed, and the form can be supported with a simple combination.

The height of the upper pipe (3) from the lower pipe (1) is adjusted by turning the lever portion (2d) of the support member (2) to adjust the position of the support member (2) from the external thread portion (1a) of the lower pipe (1). By setting, the height of the upper pipe is adjusted upward as shown in FIG. 5.

The upper pipe (3) has a support member (4) coupled to its lower end, and the bottom of the support member (4) is coupled to the shaft portion in a manner that it is seated on the support ledge (2c) of the support member (2). It is in a vertical state.

That is, the support member (4) is fastened with a fastening screw (S) to the threaded hole (4d) on the flange portion (4a) side at the same time as the insertion shaft portion (4b) is coupled to the lower inner diameter of the upper pipe (3), Furthermore, the lower end of the upper pipe (3) is guided and inserted into the seating groove (4c) of the flange portion (4a), so that it is seated on the upper portion of the support 2c of the support member (2) and is attached to the shaft portion (2b). It is possible to support the upper pipe (3) with the inner diameter of the insertion shaft portion (4b) being guided.

By combining the support member 4, the lower end of the upper pipe 3 is seated on the support 2c of the support member 2 as described above, so that the posts 10 supporting the form are connected to the lower pipe 1. The upper pipe (3) can be supported by standing straight and vertical.

The upper pipe (3) in the supported state as described above has a shape that minimizes bending deformation due to vertical load by forming angled recesses (3c) and protrusions (3b) on its outer shape, and is made of a relatively light aluminum steel pipe to help the operator. It is easy to handle and transport and install on site.

When the upper pipe (3) is separated from the support member (2), the outer diameter of the flange portion (4a) of the support member (4) coupled to the lower end of the upper pipe (3) is the upper end of the support member (2c). It is formed with a diameter larger than the diameter, and when spaced apart from the formwork, the upper pipe ( 3) can be easily separated.

On the other hand, the support member 4 coupled to the upper pipe 3 may occur in the process of individually separating the upper pipe from the support member and collecting each material during the demolition process after installation of the post 10 and completion of construction of the slab layer. Damage to the upper pipe can be prevented in that it can compensate for possible distortion of the lower end of the upper pipe.

Preventing damage to the upper pipe (3) by the support member (4) as described above can be said to be a very important aspect in the future use of the post (10).

For example, if the form is supported in a state where it cannot be precisely erected perpendicular to the support member (2) due to damage to the lower end of the upper pipe (3), the damaged lower part of the upper pipe will fall short of the rated load, causing the post to buckle. The occurrence of this phenomenon can cause a major accident, and as described above, the support member (4) serves not only to connect the support member (2) to the upper pipe in an upright position, but also to prevent deformation of the lower end of the upper pipe. Perform.
