The member referred to may be regarded as a member conforming to these criteria.

First, as shown in Fig. 1A and Fig. 1B, which is a partial exploded cross-sectional view of the portion “L” of Fig. 1A, and in Fig. 2, which is an exploded perspective view associated with a pedestal, a first form of support assembly A according to the present invention ( An aspect is a pedestal 10, which serves as the main support and is arranged at a certain interval on the floor, in particular at each vertex of a rectangle having a certain size, and a stringer which connects the pedestal and the pedestal to the main. 30, and a panel 50 mounted on the head 17 of the pedestal 10 and the stringer 20.

As shown in FIG. 2, the pedestal 10 includes a base plate 10 contacting the ground 59, a lower support 13 integrally raised above the base plate, and provided with a female screw, and the lower support. The male screw is formed to be screwed to include an upper support 15 for performing a height adjustment function, and a head 17 arranged on the upper support and being one of the cores of the present invention.

The lower support 13 and the upper support 15 is coupled to the fixing nut (15A) on the exposed contact surface to prevent loosening after adjusting the length.

The head 17 is inserted and fixed to the upper end of the upper support 15 in the hollow 17a of the truncated inverted cone portion 17A,

The upper end of the cone portion 17A is formed with a circular central protrusion 17B (see FIG. 2) which forms a concentric circle with the hollow 17a by the support portion 17E which is relatively bent.

Four fastenings formed at the same height as the support portion 17E (and therefore bent relatively low compared to the central protrusion) and arranged crosswise around each other in a cross shape and bent relatively lower than the central protrusion. (17C),

And four coupling parts 17D arranged at the same height as the support part 17E and formed between the fastening part 17C and the fastening part,

The support portion 17E serves to connect the central protrusion 17B, the fastening portion 17C, and the coupling portion 17D to each other.

In the head 17, the key point is that each part is formed to have the same thickness, so that it is thin and material saving effect can be obtained, and the production cost can be lowered.

In addition, since the cone portion 17A, the central projection portion 17B, and the [fastening portion 17C + coupling portion 17D + support portion 17E] are not coplanar, they may serve as a kind of reinforcement. It is able to withstand the stress acting in the vertical direction even if it is made of thin plate, and

Due to the difference in height between the central protrusion 17B and the [fastening part 17C + coupling part 17D + support part 17E part], the stringer 30 or the reinforcing member 40A is attached to the fastening part 17C.

Alternatively, a reinforcement member stronger than the stringer 30 is introduced at a regular place in order to reinforce the entire access floor support assembly A. FIG.

In particular, the reinforcing member, as shown in Figure 1b, in consideration of the material cost problems and ease of processing and cutting, using a material having a stronger strength than the stringer 30, while using the same material as a conventional stringer To get stronger strength

A thicker material than the stringer 30 was used, and furthermore, a square tube 40A was adopted.

In order to maintain the smoothness of the head 17 when employing a thicker reinforcement tube 40A than the stringer 30 in this way

The fastening part 17C ', which is also formed with the fastening hole 17c', is formed to be bent lower than the fastening part 17C for the stringer 30 so that the reinforcement angle tube 40A is coupled through the corresponding fastening hole 41a. It is,

The reinforcement angle tube 40A and the fastening portion 17C 'are relatively longer than the bolt B1 for the stringer, so that the bolt B2 penetrating the reinforcement angle tube is each fastening hole 17c' (41a). It is fitted in and fastened.

The fastening portion 17C 'of the head 17 to which the reinforcement tube is connected may be provided with one or two or more of the four fastening portions as needed (in FIGS. 1B and 2, one fastening portion 17C' is provided. Thus there are three fastenings 17C for the stringer).

For example, as shown in FIG. 1C for a modified access floor support assembly with a major difference in that the reinforcement tube is provided at both fastening portions of the head as compared to the first form shown in FIG. Is a plan view and [I] is a schematic side cross-sectional view),

In the illustrated head 17 ', the reinforcing angle pipes 40A are respectively coupled to the corresponding fastening portions 17C' arranged at both symmetrical positions, and relatively short bolts B1 are screwed into the fastening holes 17c 'and 41a. Are combined.

Next, the present invention covers the cushion pad 20 on the head 17 of the pedestal 10 so as to implement functionality such as smoothing of the head of the pedestal, reinforcement of a buffer role, and ease of alignment of the panel. .

Specifically, the cushion pad 20 cancels the fine height difference between the central protrusion 17B of the head 17 and the fastening portion 17C,

It serves to cover the gap of the head, the stringer, the reinforcement tube,

The unique cushioning of the material complements the role of reducing sound insulation and shock transmission.

The cushion pad 20 has a shape covering the support part 17E and the four coupling parts 17D of the head of the pedestal 10, 17.

In addition, a skirt 21 covering the side surfaces of the four engaging portions 17D of the head is extended,

A through hole 27 is formed to surround the outer circumferential surface of the central protrusion 17B of the head.

As can be seen in Figure 1b, the panel 50 is laminated in various ways depending on the purpose of antistatic, noise reduction, buffer, interior function,

Typically classified in the industry as wood panels and inorganic panels,

Traditionally, the panel 50 and the panel are opened due to the in-situ induction protrusion such as the partitioning protrusion 25 formed on the cushion pad 20 according to the present invention, instead of forming the inclined portion 51 vertically. It is not to be supported.

As described above, the access floor support assembly A consisting of the pedestal 10, the cushion pad 20, the stringer 30, the reinforcing member 40A, and the panel 50 is installed in an indoor space of a predetermined area, In the duct 55 and the electric tray 57 is arranged in place.

Next, Figs. 3A ([A] and [B] are cut in different directions (90 degrees apart) ([A] is a separate plan view of the head portion). A cross-sectional view of the access floor support assembly A is shown.

The main difference between the two forms is that the assembly A of FIG. 3A is a rectangular grooved member 40B in the reinforcing member, and the reinforcing member 40B is located below the head 17 of the pedestal 10. The upper support 15 is fixed by the nut 15B coupled to the lower part in the inserted state.

In addition to being thicker than the stringer 30, the rectangular tube groove member 40B has not only a simple rectangular tube groove shape but also has an extension portion 43 bent inward in the lower portion thereof to improve the reinforcement function.

In addition, in Figure 3a to prevent the interference between the rectangular groove-shaped reinforcing member (40B) and the stringer (30)

One of the differences from the assembly form of FIG. 1A is that a cutout 35 is formed at the contact end of the stringer with respect to the reinforcing member 40B.

In addition, although not shown in detail, the degree of formation of four fastening portions of the head 17 lower than that of the central protrusion 17B differs in uniformity.

FIG. 3B ([A] and [B] are cut in different directions (90 degrees apart) ([A] is a separate plan view of the head portion) from the assembly of the second type shown in FIG. A variant access floor support assembly (A) of the same concept but with a major difference in that the height of the head 117 of the pedestal 10 is higher and there is no joint for the cushion pad is shown.

Such a head may also be formed to be processed to have the same thickness as the conventional pedestal, rather than processing the iron ball.

3A and 3B, the cushion pads 20 and 120 covering the heads 17 and 117 of the pedestal 10 also correspond to the shape of the head (in FIG. 3B, reference numeral 125 denotes a partition protrusion). ).

Next, Fig. 4 ([A] and [B] are cut in different directions (difference of 90 degrees)) ([A] is a separate plan view of the head portion). 3A is shown in FIG. 3A in that the reinforcing member is a rectangular grooved member 40B, compared to the two models described above, and is mounted on the fastening portion 17C of the head 17 of the pedestal 10. It is similar in that it is combined.

However, the reinforcing member 40B is mounted on a part of the coupling part 17D together with the fastening part 17C,

Accordingly, the cushion pad 220 also has a form located between the two reinforcing members (40B).

As described above, the access floor support assembly according to the present invention has frequent entrances, such as stairs or doors adjacent to the door, and areas where other heavy objects will be placed, or regularly placed in place. And a conventional stringer connecting the pedestal with a pedestal having a head on which the panel is mounted together with the reinforcing member, and the stringer or the reinforcing member When mounted on the thin head of the pedestal and fastened, a cross-shaped four-shaped four-headed structure is formed to be relatively low due to the central protrusion so that the smoothness of the head is not broken by the stringer or the reinforcing member. To have a fastening, and furthermore the smoothness of the head of the pedestal By introducing cushion pads with functions such as reinforcement of cushioning, cushioning role, and ease of arrangement of panels, the prior art of Patent Registration No. 0230069 and Utility Model Registration No. 0147555 (related to FIGS. 11 to 14 in the patent publication) As shown in), each pedestal is used for panels covered by finishing materials such as real tiles, starting from a model that is still the most used or applied in the access floor industry, and simply switching the concept. The head and the head as a whole can be smoothly installed so that there is no problem.
