Abstract

PURPOSE:To make an opening easy by vertically providing a bearing leg to lay a large number of block bases forming a wiring space, and eliminating at least one block base to make the opening with an opening and closing lid. CONSTITUTION:A large number of block bases 2, to which a bearing leg 5 is vertically provided, are laid on a floor 1, and a wiring space 3 is formed between the bases 2 and the floor 1. An opening 6 is formed by eliminating at least one block base, and the opening 6 is blockaded with an opening and closing lid. By the method, maintenance and re-wiring can be easily made.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a raised floor used for forming the floor of a computer room or the like.

. [Prior Art] Raised floors generally have a block base with supporting legs above the floor surface. However, in the conventional model, the floor surface was covered only with a block base.

[Problem to be solved by the invention]

However, in such prior art, when changing the wiring connection, the floor panel located above the joint box must be removed using a special tool, and the position of the joint box is not above the block base. It was difficult to work because it could not be visually recognized.

The object of this invention is to be able to easily open a portion of the block base corresponding to a key point such as wiring maintenance or wiring change without using a special tool, and to easily open such a portion. The purpose is to provide a raised floor that can be checked.

[Means to solve the problem]

In the free access floor of the present invention, support legs are hung from a block base main body to form a block base, a large number of block bases are laid on the floor surface, and wiring is wired between the block base and the floor surface. In the free access floor where a space is formed, an opening is formed by removing at least one of the block bases, and this opening is closed with an opening/closing lid.

[Effect]

According to the configuration of the present invention, an opening is formed by removing at least one of the block bases, and this opening is closed with an opening/closing lid, so that maintenance and wiring changes can be performed by opening the opening/closing lid. It is possible to easily open the part of the block base corresponding to the point location such as.

Furthermore, such locations can be easily confirmed due to the presence of the opening/closing lid.

〔Example〕

An embodiment of a free access floor according to the present invention will be explained based on FIGS. 1 to 4. The raised floor has wiring space 3 between block base 2 and floor 1.
is formed.

As shown in FIG. 2, the block base 2 is formed by suspending support legs 5 from a block base main body 4. The parts of the block base 2 that are key points for wiring maintenance and wiring changes (for example, the joint box 7
An opening 6 is formed in a portion corresponding to the installation location), and this opening 6 is closed with an opening/closing M9. The opening 6 is formed by removing at least one of the block bases 2. 20 is a carpet arranged on the upper surface of the block base 2.

10 is an opening frame attached to the opening 6, and an outer flange 12 and an inner flange 13 for locking are formed on the upper and lower edges of the frame body 11. A fixing screw 14 is attached to opposing parts of the inner flange 13, and this fixing screw 1
A fixing metal fitting 15 is screwed onto the fixing screw 1.
A regulating body 16 is disposed on the side of 4 to prevent swinging of the fixing metal fitting 15. Therefore, when the fixing screw 14 is rotated,
The fixing fitting 15 moves up and down along the fixing screw 14. The opening frame IO is attached to the opening 6 by sandwiching the edge of the opening 6rIR between the outer collar 12 and the fixing metal fittings I5, as shown in FIG. The opening/closing lid 9 closes the opening 6 while being supported by the inner flange 13 of the opening frame 10. The opening/closing lid 9 covers the panel material 1.
The panel member 17 has hooks 19 on both sides of the panel member 17 for opening and closing.

Note that a marker may be provided on the upper surface of the opening/closing member 19, or a display element such as a neon lamp or LED connected to the floor wiring may be attached to facilitate confirmation of the energization state.

〔Effect of the invention〕

According to the free access floor of the present invention, it can be opened easily without using a special tool, and the location to be opened can be easily confirmed, improving work efficiency.
