Description

[Detailed description of the invention] The present invention provides a hanging device that can be used by attaching to an I-beam beam at a construction site, for example, to hang a scaffolding support from the I-beam. This is what we provide.

Hereinafter, one embodiment of the present invention will be described based on the attached illustrative figures. 1 is a main body, 2 and 3 are U-shaped clamps. The main body 1 is made up of two strip-shaped side plates 4a and 4b that are arranged in parallel with an appropriate spacing and are fixed and integrated with each other at both ends.
Mounting holes 5 for hanging are provided in a and 4b so as to face each other at appropriate intervals in the length direction.
a, 5b, 6a to 6d, 7a, and 7b are provided. The U-shaped clamps 2 and 3 have the same structure and are arranged to face each other, and each screws through a U-shaped member 8 and a through screw hole 9 on the upper side 8a of this U-shaped member 8. A pressing disc spring 11 is rotatably coupled to the lower end of the clamping screw 10, and a rotation operating portion 12 (bolt head shape as shown in FIG. 1 or The ring shape shown in FIG. 4 or any other shape may be used. The U-shaped clamps 2 and 3 are moved upwardly in the longitudinal direction of the main body 1 by means of vertical fixing screws 13 and 14 that extend between the side plates 4a and 4b of the main body 1 so as to be movable in the longitudinal direction. It is fixedly installed. The fixing screws 13 and 14 pass upward through slide washers 15 and 16 attached to the lower sides of the main body side plates 4a and 4b, and their upper end threads are attached to the U-shaped members 8 of the U-shaped clamps 2 and 3. Lower side 8 in
It is screwed into a through screw hole 17 provided in b.
18 is a through screw hole provided on the vertical side 8c of the U-shaped member 8. As shown in FIG.
The upper and lower sides 8a, 8b and the vertical side 8c of
Each of the fixing screws 13, 14 has a hat-shaped cross section with the recess facing inside, so that the upper end threaded portion of the fixing screws 13, 14 does not protrude from the inner recess of the lower side 8b even in the screwed and fastened state. It can be a state.

Note that the side plates 4a and 4b of the main body 1 can be fixed to each other not only at both ends but also at the center position in the longitudinal direction by using other suitable connecting members.

To explain one usage example of the hanging device configured as above, both U-shaped clamps 2 and 3 are connected to a distance wider than the width of the lower flange 20 of the I-beam I-shaped steel 19, and the fixing screws 13 14 is loosened and moved in the length direction of the main body 1. Then, U-shaped clamps 2 and 3 are placed on both the left and right sides of the I-type steel lower flange 20.
The main body 1 is attached to the I-type steel lower flange 2 in order to
0, and move both U-shaped clamps 2 and 3 inward, respectively, to fit the left and right side edges 20a and 20b of the I-beam lower flange 20 into the respective U-shaped members 8. Make it fit. In this state, screw in the fixing screws 13 and 14 to fix the U-shaped clamps 2 and 3 to the main body 1, and then tighten the U-shaped clamps 2 and 3.
The left and right edges 20a of the I-shaped steel lower flange 20 are inserted between the pressing disc spring 11 at the lower end and the lower side 8b of the U-shaped member by screwing in the clamping screws 10, respectively.
Clamp 20b.

By the above-mentioned mounting operation, the main body 1 can be mounted symmetrically below the lower flange 20 of the I-shaped steel 19. As shown in FIG.
When suspending the main body 1, the upper end plate 22a of the hanging attachment 22 protruding upward from the center of the support 21 is attached to the side plates 4 of the main body 1.
a, 4b, and fix the main body 1 and the plate 22a by means of bolts and nuts 23 passed through the mounting holes 5a, 5b on the main body 1 side, for example, to fix the main body 1 to the plate 22a. The support 21 can be suspended. In addition, any temporary material to be hung can be hung using any of the hanging holes 5a to 7b of the main body 1.

The hanging device for temporary construction work of the present invention, as in the above embodiment, has a hanging main body which is made up of both side plates arranged in parallel at an appropriate distance and integrally connected to each other at least at both ends, and a hanging device attached to the upper side of this main body. a pair of opposing U-shaped clamps, the U-shaped clamps being fixed in the longitudinal direction of the main body by a fixing screw passing upwardly between both side plates of the main body so as to be movable in the longitudinal direction. It consists of a U-shaped member that is movably and fixedly attached, and a clamping screw that threads through the upper side of this U-shaped member and clamps and fixes the lower side edges of the I-shaped steel between it and the lower side. Therefore, by changing the interval between the pair of U-shaped clamps, the main body can be made safe and strong by using the pair of U-shaped clamps on the lower flange of the I-beam beam regardless of the width of the lower flange. The main body thus attached can be used to safely suspend necessary temporary suspension materials, such as suspension scaffold supports, from the I-beam beam. Moreover, the pair of U-shaped clamps are
Since the general-purpose U-shaped clamp used alone or in combination with a pipe clamp can be used, it can be manufactured at a very low cost.
