The present invention relates to a support post for a floor structure formed by installing panels spaced apart from the floor during the installation work of a clean room, and more particularly, to a support post of an improved structure to increase the coupling stiffness between the screw rod and the support plate will be.

In general, when installing a clean room, the floor is formed by installing a floor panel spaced apart from the concrete floor so as not to be affected by vibration, etc., as shown schematically in FIGS. 1 to 3. The panel 3 is installed on the H beam 2 fixed to the upper end of the support post 1 installed at a predetermined interval.

As such, the support post 1 for installing the floor structure is composed of a support plate 5 fixed to the anchor bolt 4 on the concrete floor, and a screw rod 6 coupled to the support plate, and adjusting the fastening height at the screw rod. To allow the entire floor to be installed horizontally.

Four or two screw rods 6 are coupled to the backing plate 5 as shown in FIGS. 2 and 3 as necessary.

The coupling structure of the conventional support plate 5 and the screw rod 6 is formed in the upper surface of the support plate is formed with a locking jaw portion 7 is enlarged in diameter at the height of the bottom plate thickness from the bottom of the screw rod as shown in FIG. In the supported state, the protrusion 8 below the locking jaw 7 is welded to the hole 9 of the support plate.

However, the lower end of the screw rod and the welding work on the bottom surface of the base plate 6 in the flat state takes a long time, there is a problem that the work productivity is deteriorated, and a skilled worker for the welding work is required.

As a countermeasure for the coupling operation of the support plate and the screw rod by the conventional welding, as shown in FIGS. 5 and 6, the engaging portion of the support plate to which the screw rod is coupled is formed to protrude upward, and the protrusion of the lower side of the locking jaw of the screw rod ( 8) was allowed to engage with the support plate by punching the end of the protrusion from the bottom of the support plate to the periphery of the hole 9.

However, even in the coupling structure of the conventional support plate and the screw rod of this improved structure, the screw rod and the support plate are weak due to the weakening force of the punching between the screw rod and the support plate when tightening the nut in order to fix the angular pipe to the screw rod. As the coupling part of the plate is separated and the screw rod is rotated with respect to the support plate, the nut cannot be tightened frequently, which causes a problem in the bottom plate installation work.

The present invention is to solve the problem of the screw rod and the support plate coupling structure of the support post for installing the bottom plate in the conventional floor structure, the screw rod by the rotational force to tighten the nut in coupling the screw rod to the support plate by the punching process It is an object of the present invention to provide a support post for a floor structure of an improved structure in which a screw rod is firmly coupled to a support plate by having a structure that does not rotate relative to the support plate.

A support post for a floor structure according to the present invention for achieving the above object includes a support rod and a support plate, the support rod is a screw rod formed with a screw and a locking jaw portion having a larger diameter of the lower side thereof, and a lower side of the locking jaw portion A support post for a floor structure formed with a hole to project a protrusion formed at a lower end of a support rod to protrude and coupled to a support plate, wherein the support force is applied to a rotational force when tightening a nut to a screw rod of the support rod. At least one pair of grooves are formed at positions opposite to the inner walls of the holes of the support plate so that the projections at the bottom of the support plate are engaged with the grooves of the hole by a portion of the bottom of the support plate spread by the impact in the punching process by the punching process. .

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

7 is an exploded perspective view of the support post 10 of the improved structure according to the present invention. The support post 10 for a floor structure according to the present invention includes a support rod 11 and a support plate 20. The support rod 11 is a screw rod 12 having a screw and a locking jaw portion 13 having a larger diameter at the lower side thereof, and a protrusion 14 protruding downward from the bottom of the locking jaw portion, as in the conventional support rod, and coupled to the support plate. ) Is the same as the conventional support rod.

According to the present invention, the supporting plate 20 has holes 21 formed to fix at least two support rods, and the holes are formed at positions in which the grooves 23 are opposed to at least two places on the inner wall 22, FIG. 7. In the embodiment shown in and 8, two pairs of grooves 23 are formed at opposite positions, and are configured to engage the grooves when engaging the protrusions 14 at the lower ends of the supporting rods to the holes 21.

That is, by forming the groove 23 in the inner wall of the hole 21 formed in the support plate, the bottom surface of the support plate when fitting the projection of the lower end of the support rod 11 through the hole of the support plate 20 as shown in FIG. By hitting the protrusion 14 at the lower end of the supporting rod 11 protruding from the punching process, the protrusion 14 is spread laterally and is engaged with the periphery of the hole at the bottom of the support plate.

At this time, the spreading portion of the protrusion 14 at the lower end of the supporting rod spreading around the hole by the punching process is also inserted into the groove 23 formed in the inner wall of the hole 21, so that the supporting rod is rotated not only in the axial direction but also in the rotational direction with respect to the supporting plate. In addition, when the nut is fastened to the screw rod to fix the angle pipes for the bottom panel support to the screw rod of the support rod, the support rod is not rotated with respect to the hole and is firmly coupled.

According to the present invention, in the support post for supporting the bottom structure, a plurality of grooves are formed in the inner wall of the hole of the support plate in the structure for coupling the support bar to the support plate, and the protrusions at the bottom of the support bar are inserted into the holes of the support plate by a punching process. Part of the protrusion that is spread by punching when combined with the insert into the groove is firmly engaged, there is an advantage that can improve the work efficiency by automating the manufacturing process compared to the case of manufacturing by conventional welding, and also in the present invention Accordingly, in the punching process, the spreading portion of the protrusion 14 is inserted into the recess 23 formed in the inner wall of the hole 21 so that the supporting rod has sufficient supporting force in the rotational direction as well as the axial direction with respect to the support plate. Compared with the assembly structure, there is a very solid advantage.
