Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a frame for mounting electronic components and the like, and particularly to a structure for installing an electronic switching device frame on a floor.

Conventionally, when installing a frame for an exchanger on a floor, fixing holes are provided in the bottom of the frame, and bolts are passed through the fixing holes to fix the frame on the floor.

The structure of a conventional exchanger frame and the method of installing it on the floor will be explained with reference to FIGS. 1 to 3.

FIG. 1 is a perspective view of the frame structure, FIG. 2 is a partially enlarged view of the frame structure, and FIG. 3 is a structure for fixing the bottom surface of the frame frame to the floor surface.

Commonly used symbols in the figures indicate the same thing,
11 is a frame, 12 is a base plate, 13 is a back plate for supporting the unit shelf, 14 is a hole through which a bolt is passed to fix the frame to the floor,
15 is a bottom plate of the frame, 16 is a bolt, 17 is a horizontal level adjustment liner, and 18 is a floor.

When fixing the frame 11 shown in FIG. 3 on the floor 18,
First, the liner 17 and the base plate 12, whose horizontal levels have been adjusted in advance, are placed at the position on the floor 18 where they should be installed.

Next, place the frame 11 on the plywood so that the fixing bolt holes of the base plate 12 and the frame fixing holes 14 match, and roughly align the frame bottom 15 and the base plate so that the frame bottom 15 is horizontal. The horizontal level adjustment liner 17 between the frame frame 12 and the horizontal level adjustment liner 17 is adjusted again, and finally the bolt 16 is fixed to the floor surface 18 through the frame bottom surface 15, the liner 17, and the base plate 12.

In such a frame structure, as shown in FIGS. 2 and 3, firstly, the fixing holes 14 for fixing the frame are located inside the bottom surface 15 of the frame 11, so it is difficult to tighten the bolts 16. The work is difficult. Secondly, when the frame 11 is set vertically on the floor, it is necessary to remove the plywood under the frame and reinsert the level adjustment liner (board) 17 depending on the levelness of the floor. - Since each frame requires installation in two locations, it takes a considerable amount of time to install the frame when multiple rows are lined up, resulting in poor work efficiency.Additionally, there is not enough space to insert and tighten the bolts into the fixing holes on the bottom of the frame. Even after the equipment is mounted on the rack, this space must be provided within the equipment mounting area of the rack for holding, adding, removing, etc.
The following have drawbacks, such as poor mounting efficiency such as inability to accommodate devices.

The purpose of the present invention is to eliminate the above-mentioned drawbacks, to facilitate horizontal level adjustment by connecting two pieces of plywood for fixing the frame, and to enable horizontal leveling by installing the plywood in advance without adjusting the frame. Fixing holes for the frame are provided in the frame support plate connected to the frame so that it can be removed, and the fixing holes are eliminated from the inside of the frame to increase installation work efficiency and device mounting efficiency. The purpose is to provide a frame structure.

In order to achieve the above object, the present invention provides a frame having a U-shaped frame support plate extending perpendicularly to the frame on the bottom surface of the frame, and The plywood is constructed by connecting two U-shaped base plates that fit together by a connecting plate, and the plywood is fixed to the floor surface on which the frame is installed, and then the plywood and the frame support plate are attached to the frame. It is characterized by being connected outside the frame.

The frame structure of the present invention and its installation method are shown in Figures 4 to 6 below.
This will be explained in detail with reference to the embodiments shown in the figures.

FIG. 4 is a perspective view of the frame structure and plywood of the present invention, FIG. 5 is a partially enlarged view of the frame structure and plywood, and FIG. 6 is a partial sectional view of the frame installed on the floor.

Common symbols in the drawings indicate the same things, 41 is the frame, 42 is the U-shaped base plate, 43 is the unit shelf support back plate, 44 is the U-shaped frame support plate, 45 is the bottom of the frame, 421 is a plywood connecting plate, 423 is a frame fixing hole, 424 is a plywood fixing hole, 4
41 is a fixing hole, 46 is a bolt for fixing the plywood to the floor,
47 is a liner for horizontal level adjustment, 48 is a floor surface, 442
are the bolts that secure the frame to the base plate.

As shown in FIG. 6, the frame 41 and frame support plate 44 shown in FIG. 5 are constructed such that the frame support plate 44 is embedded in the bottom surface 45 of the frame in a direction perpendicular to the frame and bonded by welding or the like.

The frame support plate 44 protruding to the outside of the frame is provided with a fixing hole for fixing to the base plate 42.

On the other hand, the two base plates 42 are connected to the connecting plate 42 as shown in FIG.
1.

The base plate 42 has a fixing hole for installing the floor surface 48 and a fixing hole 441 for installing the frame support plate 44, and furthermore, the base plate 42 engages with the frame support plate 44 and has a fixing hole for installing the frame support plate 44. It also functions as a guide rail when installing.

Next, a method for installing the frame 41 having the above structure on the floor surface 48 will be explained.

First, the base plates 42 connected by the connecting plates 421 are placed on the floor surface 48 on which the frame 41 is installed, and a liner (board) 47 for level adjustment is laid so that the two base plates 42 are horizontal, and the liner (board) 47 is placed between the plywood boards. After leveling is completed, it is fixed to the floor using bolts 46.

Next, when the frame 41 is placed on the base plate 42 and the frame support plate 44' is correctly assembled to the base plate 42, the frame support plate 44 on the outside of the frame is fixed to the base plate 42 with bolts 442. The entire frame 41 is installed on the floor surface 48.

According to this configuration, devices can be mounted close to the bottom of the frame, as shown by the broken line B in FIG. 6, without requiring a space for tightening bolts within the frame.

The shape of the frame is not limited to this embodiment, and may be a frame provided with unit shelves or the like in advance.

As explained above, according to the present invention, the following effects can be obtained.

(1) Two pieces of plywood can be connected and the plywood can be installed horizontally on the floor in advance, separate from the frame.

(2) The frame is placed on top of the plywood that has been placed horizontally in advance, and the plywood can be connected to the support plate glued to the frame on the outside of the frame, increasing the efficiency of the work of fixing the frame.

(3) Since the base plate serves as a guide rail for the frame, the frame can be positioned simply by placing the frame on the fixed plywood.

(4) By providing frame fixing holes outside the frame, the device mounting area becomes wider and mounting efficiency improves.

(5) Since the frame support plate and the plywood extend perpendicularly to the frame, the stability of the frame relative to the floor is increased.
