Description

[Detailed description of the invention] This invention relates to the attachment part of locking fittings such as temporary frames and scaffolding frames to the building body when constructing steel structures such as general houses, warehouses, gymnasiums, and factories. .

In steel-framed buildings, the main framework uses so-called channel steel, C-shaped steel, or channel steel, which has a groove-shaped cross section. They are attached by direct welding, and these connecting rods and nuts are used to support and fix temporary members such as scaffolding frames.

However, these welding methods have some inconveniences, such as the welded parts sometimes getting in the way in the next process and needing to be removed, and sometimes becoming an obstacle to exterior work. existed.

The present invention provides a member for fixing to a C-shaped steel such as a scaffolding frame, which is easier to install, easier to remove, and does not have a complicated structure compared to the conventional welding fixing method as described above. The purpose is to

The member to be attached to the shaped steel of the present invention is to tighten the member inserted into the channel of the C-shaped steel and a flat plate provided to close the opening of the flange with bolts, and sandwich the flange of the shaped steel between the two plates. At the same time, a long nut is welded horizontally to the outside of the flat plate, and a threaded portion is engaged with this nut to the end of the connecting member of the scaffolding frame to fix it.

Therefore, by using the fixing member of the present invention, when constructing buildings such as general houses or warehouses made of steel using shaped steel such as C-shaped steel, temporary frames or The scaffolding frame can now be installed extremely easily, and the installation work to the building's steel frame can be done without the need for workers with special skills such as welders.
Moreover, it can be removed and relocated if necessary.
It can be easily done without using any special tools, and the installed item takes advantage of the elasticity of the steel material.
It can be fixed securely.

It also has the advantage of being able to be dismantled using only tools such as spanners. Next, the present invention will be explained with reference to the drawings. A shaped steel 1 such as a C-shaped steel used for the frame of a building has flanges 2 formed on both sides facing an opening 3.
Then, using this opening 3, the flanges 2 on both sides
The inner member 6 and the outer member 10 of the fixture 5 are placed so as to be in contact with both side surfaces of the fixture 5, and both members 6 and 10 are tightened with bolts 15.

Then, using nuts 13 fixed to predetermined locations of the outer member 10 by welding or the like, the ends of the connecting members 4 that fix the scaffolding frame or the like are screwed.

The details of each component of the fixture 5 are as shown in FIGS. 2 and 3. The inner member 6 is formed from one flat plate as shown in FIG.
and leg portions 8 formed by bending on both sides thereof,
8', and is formed into a substantially trapezoidal shape when viewed from the side.

A female threaded hole 9 is provided in the center of the flat plate 7. This screw hole 9 engages with the male thread of the bolt 15 when fixing the above-mentioned fixture 5 with the bolt 15, and presses the leg portion 8 of the inner member 6 against the flange 2.

By this pressing, the legs 8 are opened laterally and pressed against the corner of the starting end of the flange 2, and are fixed in the state shown in FIG. 1.

As shown in FIG. 3, the outer member 10 is formed of a flat plate 11, and has a hole 12 with a diameter larger than the diameter of the bolt 15 in the center, and a connecting nut 13 at a predetermined position on the side surface of the welded part 14. It is fixed by.

Since the fixture 5 of the present invention has the above-mentioned configuration, the inner and outer members sandwich and fix the flange of the shaped steel, and by this fixation, the connecting member 4 of the scaffolding frame can be reliably supported to the shaped steel. , so that it can be fixed. Also, when inserting the inner member 6 into the space of the steel mold 1, the width of the inner member 6 is made narrower than the opening 3 of the steel mold 1, and the length of the member 6 is smaller than the width of the internal space of the steel mold 1. Since it is short, insert the member 6 through the opening 3, rotate it 90 degrees inside to set it in the state shown in the figure, place the outer member 10 on the outside of the flange 2, and tighten both bolts 15 to fix them. This results in the fixed state shown in FIG.

Further, the bending angle of the legs 8 of the inner member 6 is set as required, and the elasticity with which the legs 8 are expanded ensures that the fixture can be held securely.

What is shown in FIG. 4 is a second embodiment of the invention.

In this example, the inner member 16 is formed from two hook-shaped members 17, 17'. The hook-shaped members 17, 17' of the inner member 16 are connected to plates 18, 1 with elongated holes 20, 20' as shown in FIG.
8', and legs 19, 19' formed by bending at right angles from this end, the leg 19 being the leg 1.
It is formed to be shorter than plate 9' by the thickness of plate 18'. Furthermore, the elongated holes 20 and 20' are formed with a margin at the end so that the joint will not bend even when the elongated hole is extended to the maximum.
These elongated holes 20, 20' allow for easy fixation to C-shaped steels of different sizes.

Further, in the example shown in FIG. 4, the bolt 15 is installed with the head facing upward so that the threaded portion protrudes from the hole 21 of the outer member 10, and is tightened with a nut 15'. The work of inserting into the internal space of the shaped steel begins with step 2 shown in Figure 5.
The two hook-shaped members 17, 17' long holes 20, 20' and the hole 21 of the outer member 10 are loosely screwed together with nuts 15', and the bolts 15 with their heads facing upward are assembled as a set and inserted into the opening of the shaped steel. Insert hook-shaped members 17, 17';
Rotate 90° inside. Next, the long holes of the hook-shaped members 17 and 17' are adjusted to extend left and right, and the legs 19 and
19' is set so that it comes into contact with the flanges 2, 2,
By tightening and fixing with nut 15',
This results in the fixed state shown in FIG.

As mentioned above, the fixture of the present invention can be used without welding or drilling into the steel shape.
It can be used to easily fix scaffold frames, etc., and can also be reused after removing the fixtures, thereby reducing the installation cost of scaffold frames. For construction work, if shaped steel is used, the temporary frame can be easily fixed, and furthermore, this mounting member can be used alone to attach to the building frame.
For example, it can also be used to hang lighting fixtures and other equipment, and can be used not only as a fixture for construction work but also for a wide range of other purposes.
