Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a mounting member for attaching a lattice frame, particularly a louver frame of a steel staircase, to a steel column.

[Prior art]

As shown in FIGS. 1 and 2, in an external steel staircase, unit louver frames 1 are provided in multiple stages on both sides thereof. This unit louver frame 1 is attached to a steel column 2 as a vertical support member.
Conventionally, an angle member 3 as shown in FIG. 3 is used. In the column side flange 3A of this angle member 3, a horizontally long long bolt hole 4 is bored, and in the frame body side flange 3B, a longitudinally long bolt hole 5 is bored, and the column side flange 3A A frame side flange 3B is attached to the inner surface of the steel column flange, and is attached to the inner surface of the vertical frame 1B of the frame body, and is fixed with bolts 6, 7 and nuts 8, 9.

In such a configuration, when installing, the angle member 3 is temporarily attached to the steel column 2.
Here, it is necessary to ensure a construction error l of 10 mm or more.

Temporarily attach the louver frame 1. At this time, temporarily tighten bolt 7 loosely.

Using the previously attached lower louver frame, adjust the position of the louver frame with canvas material and temporarily fix it.

Fully tighten bolts 6 and 7 to fix. However, such conventional mounting members using angle members have the following problems.

Installation work is complicated.

There are dangers involved in the work, such as dropping the canvas material.

If the steel frame is distorted inward (in the direction of the arrow in Figure 4), the edge of the angle material will come into contact with the web of the steel column.

A total of two workers are required, one on the inside and one on the outside.

[Purpose of invention]

This idea was devised in view of the above-mentioned problems, and its purpose was to be able to omit canvas work and to be able to perform work from the inside.
To provide a mounting member that can safely and easily attach a louver frame to a steel column.

[Structure of the idea]

The mounting members of the lattice frame according to this invention include a vertical substrate attached to a vertical support member such as a steel column, an upper unit lattice frame and a lower unit lattice frame that protrude from the vertical substrate toward the unit lattice frame. It is equipped with a spacing plate that can be positioned between the bodies, and a fastening member that is attached to the spacing plate and projects toward the upper and lower unit lattice frames.

〔Example〕

This invention will be explained below based on an illustrated embodiment. As shown in FIGS. 5 and 6, the mounting member according to this invention is disposed between the upper louver frame 10 and the lower louver frame 11, and is attached to the inner surface of the flange of the steel column 2. Vertical substrate 12
and a spacing plate having a U-shaped cross section that protrudes from the side of the central portion of the vertical substrate 12 toward the louver frame, is located between the upper frame 10 and the lower frame 11, and is capable of maintaining the louver frame spacing. 13, and a screw as a fastening member that is attached through the protruding plates 13A, 13A of the spacer plate 13 and protrudes toward the lower frame 10A of the upper frame 10 and the upper frame 11A of the lower frame 11. A rod 14 is provided.

Such a substrate 12 and holding plate 13 can be easily obtained by, for example, bending protruding plates 13A, 13A from a single plate. moreover,
As shown in FIG. 7, the threaded rod 14 is attached to the protruding plate 13A.
The holding plate 13 is attached by a nut 15 from the inner surface, thereby preventing deformation of the holding plate 13.

Vertical substrate 12 has longitudinally long long bolt holes 16 drilled in its upper and lower sides, and is attached to the inner surface of the web of steel column 2 with bolts 17 and nuts 18 so that its position can be freely adjusted.

Further, the lower frame 10A and the upper frame 11A are provided with horizontally long long bolt holes 19, and the threaded rods 14 are inserted through the bolt holes 19 and fixed with nuts 20.

In the above configuration, installation is performed in the following steps.

(i) Temporarily attach the mounting member to the upper frame of the louver frame 10.

(ii) The louver frame 10 is hung onto the previously attached lower louver frame 11 and connected to the mounting member temporarily attached to the lower louver frame 11.

(iii) Fix the vertical board 12 of the lower mounting member to the steel column 2.

(iv) Adjust the horizontal position of the louver frame 10.

(v) The louver frames 10 and 11 and the retaining plate 13 are fixed by fully tightening them.

The louver frame is installed in multiple stages by repeating the above steps, but the levelness of the louver frame is
Adjust the appropriate number of steps using the furler.

Although the example of an external steel staircase has been described above, it goes without saying that the present invention can be effectively applied not only to staircases and louver frames, but also to cases where frames are attached to vertical support members in multiple stages.

[Effect of idea]

Since the mounting member according to this invention has the above-described configuration, it has the following effects.

(i) Canvas work can be omitted by the spacing plate.

(ii) Since the construction error is determined by the long holes in the louver frame, the edge of the vertical board does not hit the web of the steel column as in the past.

(iii) Work from within.

(iv) Horizontal and vertical adjustment is easy.

(v) From the above, installation work can be carried out safely and easily.
