The present invention relates to a post head structure for assembling floor panels, such as a clean room, for installing a floor panel at a predetermined distance from a building floor by a post, such as the floor of a clean room. A post head for fixing a pad for a bottom panel of an improved structure to facilitate assembly and disassembly operations and to be easily manufactured by molding.

In general, a clean room for semiconductor manufacturing or a laboratory floor requiring a high degree of precision is spaced a predetermined distance from a building floor to form a space between the building floor and the clean room floor, and a semiconductor manufacturing device or an experiment installed on the floor. Equipment such as cables, water supply pipes, etc. required for the equipment can be installed in the space between the floor and the building floor.

As shown in FIG. 1, the floor of such a clean room is fixed to a plurality of posts 1 at predetermined intervals on a building floor, and a pad 3 is disposed on a post head 2 on the top of the post. By arranging corner portions of a plurality of, usually four, bottom panels 4 disposed adjacent thereto.

To this end, a plate-shaped post head 2 is mounted on the top of the post, and a pad 3 is formed and fixed on the post head, which is usually formed of aluminum and formed with four guide protrusions on the surface, and each protrusion is placed on the pad. Corners of the bottom panel 4 adjacent to the plane between them are arranged. At this time, the pad is usually fixed on the post head by means of an adhesive, and the bottom panel assembly position on the post head may actually deviate slightly from the center of the post head due to an error that may occur in operation, in which case the bottom panel assembly The pad is placed on the post head to an appropriate position and fixed with an adhesive, and then the rubber pad 6 is placed on the rubber pad to absorb the vibration of the bottom panel and the bottom panel 4 is assembled on the rubber pad.

However, in the case of a clean room where semiconductor production and assembly lines are installed, the equipment of the existing production line should be replaced according to the change of the production model. In this case, the line of support for the changed load and the space below the floor of the clean room should be replaced. In some cases, such as wiring, drainage, and ventilation related equipment, it is necessary to dismantle the clean room floor to replace or reinstall the post (1) and floor panel (4) in order to be suitable for the load support of the equipment installed thereon. Can be.

As such, when the bottom panel 4 is disassembled and reassembled on the post head 2 to replace or change the clean room floor, the position of the pad 3 fixed on the existing post head is replaced by the bottom panel 4 to be reinstalled. In almost all cases, the position of the pads should be adjusted according to the assembly of the bottom panel (4) on the post head (2) due to errors that may occur during the installation work. Therefore, the pad 3 fixed with the adhesive on the post head 2 as in the prior art is forcibly disassembled using a tool and reassembled as appropriate for the position of the bottom panel to be reinstalled.

However, conventionally, when the pad is adhesively fixed on the post head, it takes a long time to disassemble the pad, and in the process of forcibly disassembling the pad from the post head using a tool, the pad is damaged and cannot be reused. Therefore, there was a problem of additional burden of material cost.

In addition, when the fixing hole is formed at the center of the upper surface of the post head and the pad is fixed with the bolt, disassembly and assembly of the bottom panel pad can be easily performed. Since it cannot be uniformly disposed with respect to the center of the post head, there is a disadvantage in that pads can not be appropriately disposed and fixed according to corner portions of the bottom panel to be assembled on the post head.

As a remedy for this, the applicant of the present application discloses a pad fixing hole 14 on the upper surface of the post head 10 as shown in FIGS. 2 and 3 in the pad fixing structure for the clean room bottom panel of Korean Patent Application No. 2005-0094556. ) To form the branching holes 15 in various directions, and temporarily tighten the nut 21 extending laterally to be inserted into the branching hole at the lower end of the fixing bolt 20 passing through the pad 3, and then split the nut. Inserted through the mechanism 15, the pad was adjusted to a position to be fixed, and then the fastening was completed to fix the pad to the required position (see FIG. 3). Reference numeral 18 denotes a rubber pad for preventing slipping when the bottom panel is installed on the pad 3.

However, such a structure is to assemble the plate-like member which pre-processed the fixing bolt hole 14 and the branch holes 15 by welding or the like to the post head. It is suitable for a frame composed of H beams, if installed, and in the case of a clean room in which devices of relatively small weight are installed, smaller post heads are required, and such post heads are more efficient to manufacture by casting. . However, in this case, the head is fastened and fixed by means of stud bolts on the posts by casting, and therefore, in these post heads, bolt fastening holes and branch holes for fixing pads cannot be formed during post head molding, so they must be formed in a separate process. There was a problem.

Accordingly, an object of the present invention is to improve the structure of the post head for fixing the pad for the conventional clean room floor panel assembly, so that the post head for supporting the bottom panel of the clean room with a lighter load can be assembled to the post and cast molding It is to provide a post head having a clean room bottom panel pad fixing structure that can be easily manufactured by.

The post head having a pad fixing structure for a clean room bottom panel of the present invention for achieving the above object is formed with a hole formed on the inner side of the upper screw from the lower end to the upper center so as to be fastened to the stud bolt of the post. The side wall is formed with a groove formed with a jaw, and the fixing member formed with a hole for inserting a nut to fix the pad and fixed to the jaw and a branching hole is formed, and the sides of the post head are connected to adjacent posts. It is characterized in that the support for the square pipe coupling for protruding formed.
