Description

[Detailed description of the invention] The present invention has a structure in which the mounting bracket that connects the scaffold to the concrete structure can be extended or shortened at will and fixed in that state, so that the scaffold can be maintained at a desired distance from the structure and always firmly and firmly. This relates to improvements to mounting brackets that can be supported, and its purpose is to make installation, removal, and handling in high places extremely easy, and to prevent cement mortar, etc. from adhering to mounting screws and locking screws. This prevents the

An embodiment of the mounting bracket of the present invention will be described below with reference to the accompanying drawings.

Reference numeral 1 denotes a wall portion of the structure, and an insert 4 having an anchor reinforcing bar 2 and a flange 3 is embedded in this wall portion.

A mounting screw 5 is screwed into the female screw hole of the insert 4.

This mounting screw 5 has a screw 6 at one end and a spherical protrusion 7 at the other end.
have.

A through hole 8 is provided in the protrusion 7 in a direction perpendicular to the axial direction of the screw 6, and the through hole 8 has an hourglass shape in which the hole diameter increases from the center diameter toward the openings at both ends, as shown in the figure. There is.

One end of the locking tube 9 is fitted onto the mounting screw 5 and the protrusion 7, and the locking tube 9 is removably and rotatably pivoted to the mounting screw 5 using a U-shaped bolt 10. There is.

The above U-shaped bolt 10 connects one short rod 11 to the locking tube 9.
through hole 13, through hole 8 of mounting screw 5, through hole 14 of locking pipe 9
and insert the other long rod 12 into the through holes 15 and 16 of the locking tube 9.
The nut 17 is screwed into the screw groove at the end of the long rod, and the locking tube 9 is rotatably attached to the mounting screw rod 5.

Further, a female screw 18 is fixed to the other end of the locking tube 9, and a locking screw 19 is screwed into this female screw.

A stopper 20 is provided at the tip of the locking screw rod 19, and a clamp 2 is provided at the base end to grip the temporary scaffolding frame rod 24.
1 is rotatably provided.

In addition, in the figure, 22 is a rotating handle, and 23 is a locking screw 19.
The temporary frame rod 24 is gripped by tightening the bolts 25 of the clamp 21.

The mounting bracket according to the present invention has the above-described structure, and the mounting screw 5 is separate from the locking pipe 9 into which the locking screw 19 is screwed, and is detachable and rotatable using a U-shaped bolt 10. This allows the locking tube 9 to be pivoted.

First, the threaded part 6 of the mounting screw 5 is screwed into the insert 4 buried in the wall 1 of the structure, and the spherical protrusion 7 of the mounting screw 5 is screwed into the insert 4 buried in the wall 1 of the structure.
A locking tube 9 having a separate clamp 21 and a locking screw 19 screwed therein is fitted into the locking tube 9, and is rotatably connected by a U-shaped bolt 10.

Conventional mounting brackets have an integral screw for attaching to the proximal end of the locking pipe, which is screwed together with the locking screw.
When screwing a mounting screw into an insert on a wall in a high place, the entire mounting bracket must be rotated and screwed together, making it difficult to install a heavy mounting bracket in a high place.

However, with the mounting bracket of the present invention, only the light mounting screw 5 is screwed onto the insert 4 in advance, and then one end of the locking tube 9 is externally fitted onto the spherical protrusion 7 of the mounting screw 5. Since the locking pipe is pivotally attached to the mounting screw by the letter-shaped bolt 10, the mounting is easy and there is no need to hold the entire mounting bracket and turn it as in the conventional case.

In addition, in the present invention, the through hole 8 of the spherical protrusion 7 is not a straight hole, but the diameter of the hole is increased from the center to the openings at both ends, and the short rod 11 cannot be simply inserted into the hole and connected by tightening. The locking tube 9 can be connected at any left or right angle.

Furthermore, in the mounting bracket of the present invention, one end of the locking pipe 9 is fitted onto the mounting screw 5, and the outer pipe 23 is provided on the locking screw 19, so that the mounting bracket can be connected between the insert of the structure and the temporary frame rod. During construction, cement mortar does not adhere to the mounting screw 5 or the joint between the mounting screw 5 and the locking pipe 9, or the locking screw 19 protruding from the locking pipe, and the subsequent locking screw Since there is no problem in screwing the female screw 18, it has the effect of facilitating disassembly and reuse.

Conventional mounting brackets do not have an outer tube to protect the mounting screws and locking screws, so cement mortar adheres to the mounting screws, and unless this is removed, the screws cannot be screwed together. However, the present invention improves this point as well.
