Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a wire mounting piece for steel frame erection.

"Prior art" When constructing a steel structure, as shown in Fig. 2, a wire 2 is diagonally attached to the head and legs of the steel column 1 and wound around with a turnbuckle 3 or the like. 1 is being erected, and at that time, the wire 2 is wound directly around the steel column 1.

"Problems to be solved by the device" However, the direct winding of the above wire 2 around the steel column 1 must be performed under the condition that the foot is unstable at a high place, especially in the case of the head, It is often difficult depending on the shape and size of the steel column 1, and it may be difficult to make a work plan due to variations in the required time depending on the skill of the builder, or by holding the knot of the wire 2 on the line of action of force. Without this, the steel column 1 may be rolled up and twisted.

The present invention has been made in view of such problems of the conventional technology, and the purpose thereof is to attach the head and legs in advance during pre-construction of the steel frame, and An attempt is to provide a steel-framed dedicated wire mounting piece that has a wire fastening part on the line of action and can easily and reliably fix the wire end on the line of action of force even under conditions of unremovable scaffolding. It is a thing.

[Means for Solving the Problems] In order to achieve the above object, the steel-frame-installed dedicated wire mounting piece of the present invention has a loop-shaped arm for wire insertion upright on the surface of the plate that abuts the steel column surface. At the same time, a bolt having a screw engraved on at least both ends thereof is welded to the central portion between both legs of the arm in a manner orthogonal to the loop surface, and a nut fixed to a channel for sandwiching a steel column is attached to both ends of the bolt. That is what I did.

"Action" By properly rotating the nut, the channel can be made to substantially match the width of the steel column to be clamped.

After this adjustment, the steel columns of the channel are clamped. At this time, the back surface of the plate is pressed against the steel pillar surface.

As a result, a loop-shaped arm suitable for inserting and fixing the wire end on the line of action of the force on the surface of the steel column is erected and configured, and the wire end can be easily fixed even under poor scaffolding conditions. .

Therefore, if the overhead piece is attached in advance when constructing the steel column, the work of binding the wire can be performed accurately and quickly.
Further, since the piece is detachable, it can be diverted after the construction is completed.

[Example] An example will be described with reference to the drawings.

In FIGS. 1A to 1C, a loop-shaped arm 5 is erected by welding on the surface of the plate 4 where the back surface contacts the surface of the steel frame column 1.

Therefore, if the plate 4 is integrally fixed to the center of the surface of the steel frame column 1, the arm 5 serves as a stop portion that allows the wire to be easily inserted and fixed on the line of action of force. Is.

The structure that achieves the above-described fixation is as follows.

That is, a bolt 6 having a screw 6a engraved at least at both ends is welded 7 at a central portion between the legs of the arm 5 on the surface of the plate 4 in a manner orthogonal to the loop surface, and the steel pillar 1 is attached to both ends of the bolt 6. (It is assumed that the flange is clamped because the portion of the illustrated embodiment is H-shaped steel) and the fixed nut 9 is attached.

Then, as shown in FIG. 7B, the channel 8 is displaced by the rotation of the nut 9, and the channel 8 can be set at a position suitable for holding the steel column 1.

Reference numeral 10 in the figure denotes a bolt for fastening the channel 8. By operating the bolt 10, the proposed piece can be attached to and detached from the steel column 1.

Therefore, when the main body piece is attached in advance when the steel frame pillar is erected, normal wire tension can be promptly performed without being influenced by the skill of the singer.

"Effects of the Invention" Since the present invention is configured as described above, it has the following effects.

In order to secure the steel frame erection accuracy, the procedure of erection is included in the erection plan, and the jig (main item) is prepared in advance to ensure reliable and efficient work. , Target accuracy can be expected.
