Description

Scaffolding hanger device for scaffolding {CLAMPING APPARATUS FOR FOOTBOARD}

The present invention relates to a scaffolding scaffolding device for fixing a scaffolding scaffold to a scaffolding pipe. More specifically, the scaffolding scaffolding device is easy and quick to install and dismantle. As a locking means for maintaining the clamping release state of the clamp, the locking projection protruding from the clamp, the locking projection is inserted to guide the vertical sliding rotation of the locking projection to prevent the clamping of the scaffolding pipe is prevented from sliding downward. It relates to a scaffolding hanger device for a scaffold comprising a guide groove and a locking groove that is connected to the front or rear from the upper end of the guide groove to the engaging projection.

At the construction site of a large building, construction works are installed to enable workers to walk and sue, which is called scaffolding.

In the conventional scaffolding, a scaffolding scaffold is placed on a scaffolding pipe, which is a temporary construction temporarily installed on site, and fixed with iron wire or wire so that the scaffolding scaffold does not move.

However, in such a conventional scaffolding, the installation structure of the scaffold is usually made at a height higher than a certain height from the ground, so that the scaffold for fixing the scaffold is fixed by winding the wire or wire around the pipe in a situation where it is difficult to secure a space for work. The work was very dangerous and difficult.

Accordingly, the scaffolding hanger device for scaffolding is used to facilitate the installation of the scaffolding for scaffolding.

In the conventional scaffolding scaffolding device, as shown in FIG. 6 (hereinafter, reference numerals of FIG. 6 and FIG. 1 to FIG. 5 for explanation of the present invention are independent of each other), scaffolding for scaffolding Fixtures 23 provided on both sides of the 21 are fixed by welding, so that the fixtures 23 can be easily hooked up and detached from the scaffolding pipe 22.

The fastener 23 fixes the two pins 25 to the fixing piece 24 in which the arc-shaped locking portion 24a is formed inwardly so as to engage with the scaffolding pipe 22, thereby forming two clamps 26. The two guide slots 26a and 26b are engaged so that the clamp 26 is slidably rotated up and down, and the locking groove 26c is horizontally engaged at the lower end of the guide slot 26a positioned at the upper side of the guide slots 26a and 26b. It is configured to be able to maintain the state in which the clamp 26 is rotated.

In order to remove the scaffold scaffold 21 from the scaffold pipe 22, the fastener 23 pivots the clamp 26 upward to open the opening of the locking portion 24a for the scaffold dismantling operation. In one condition, the scaffold 21 must be lifted out.

By the way, for the stable fixing of the scaffolding scaffold, at least four fasteners 23 must be provided on both sides of the scaffolding scaffold,

When removing the scaffolding scaffolding, the clamps 26 of the respective fixtures 23 should be sequentially slid upwardly, and in the case of the conventional fixtures 23, the locks capable of maintaining the upward sliding pivoting state of the clamps 26 are fixed. Since the means is not provided, frequently during the clamping release operation of the fixture, the clamp of the clamped release fixture naturally falls, i.e., slides downward, by clamping the work, and thus the fixture is clamped again frequently. Separation of scaffolding for scaffolding and dismantling of scaffolding is very cumbersome.

In other words, unless the clamping of the plurality of scaffolding hanger devices provided on the scaffolding scaffold is performed at the same time, the unclamped fasteners are easily clamped again, so care must be taken when removing the scaffolding scaffold. This is annoying and time consuming.

As another prior art, there is a registered utility model No. 20-0450222 "work scaffold fixture",

The registration utility model, as shown in Figure 7 (hereinafter, Figure 7 for explaining the prior art and the reference numerals of Figures 1 to 5 for the description of the present invention are not related to each other), the opening (1) is The holding fixing piece 10 is formed, and the operation holding piece 30 is coupled to be rotatable in the fixing pins (20, 21), the vertical portion 42 and the horizontal portion on the upper portion of the operating holding piece (30) A rotating handle 40 made of 44 is provided, so that the rotating handle 40 is inserted into the holding groove formed in the upper portion of the holding fixing piece 10 so that the opening 1 is kept open. 30 has a configuration in which it is locked.

However, in the case of the registered utility model, since the rotating handle 40 is protruded to the upper portion of the operating holding piece 30, contact interference may occur when the operating holding piece 30 rotates,

The rotating handle 40 is composed of a vertical portion 42 protruding to the upper portion of the operation holding piece 30 and a horizontal portion 44 bent in the direction of the holding fixing piece 10 at the upper end of the vertical portion. As the thickness of the rotation knob 40 becomes thin, it is easily broken, and the stability is very weak, and the space between the scaffold and the pipe is narrow, so that the worker grips the horizontal portion 44 of the pivot knob 40 for use. Difficult to do,

Particularly, when the operating holding piece 30 is rotated upward, the front end of the operating holding piece 30 invades the area within the opening 1 so that the operating holding piece 30 hits the pipe and is automatically closed by using the same. When dismantling the scaffold, even when the operating holding piece 30 is rotated upward, the pipe is in contact with the horizontal portion 44 can not be inserted into the holding groove, there is a problem that can not maintain the clamping release state.

That is, the registration utility model may be advantageous for the installation work of the scaffolding, but the same problem as that of a conventional general scaffolding hanger occurs when the scaffold is dismantled.

Accordingly, the present invention has been made to solve the above problems, it is easy to install and dismantle the scaffolding scaffold, in particular, when dismantling the scaffolding scaffolding, the clamp of the hook device downward due to vibration or other impact As a locking means, a locking projection is formed to protrude from the clamp so as to prevent the sliding rotation from being clamped again, the locking projection is inserted into the fixing piece, and the guide groove guides the vertical sliding rotation, and from the upper end of the guide groove to the rear side.

In describing the scaffolding hanger device for scaffolding according to the present invention, a non-strict approximate direction reference is specified for convenience, referring to FIG. 2, in which gravity acts on the basis of the direction facing the fixing piece 11 of the front end portion. The direction is set downward, as shown in the direction shown up and down, left and right, and in the detailed description and claims of the invention related to the other drawings unless otherwise specified, the direction is specified and described according to this criterion.

Hereinafter will be described with reference to the accompanying scaffolding scaffolding device according to the present invention.

As shown in FIG. 1 and FIG. 5, the present invention relates to a scaffolding hanger device C for fixing a scaffolding scaffold F to a scaffolding pipe P,

1 and 4, a pair of scaffolding hangers C for right and left are respectively provided on the front and rear sides of the scaffolding scaffold F having a predetermined length in the front and rear and transverse directions, respectively. The number and arrangement of the scaffolding scaffolding device C may vary depending on the size of the scaffolding scaffolding F and the design structure of the scaffolding pipe P. FIG.

As shown in Figures 1 to 5, scaffolding scaffolding device (C) according to the present invention, the body 10 is largely coupled to the scaffolding scaffolding (F) to be engaged (locked) to the scaffolding pipe (P) ), And a clamp 20 for allowing the body 10 to be fixed to the scaffold pipe P and a locking means L for maintaining the unclamped state of the clamp 20.

1 to 3 is used to install the scaffolding scaffolding F in the scaffolding pipe P having a one-stage structure,

4 and 5 are used to install the scaffolding scaffolding F in a two-stage scaffolding pipe P. As shown in FIG.

First, a first embodiment of the present invention will be described with reference to FIGS. 1 to 3.

The body 10, so that the scaffolding scaffold (F) can be mounted on the scaffolding pipe (P),

The front end portion is provided with a fixed piece 11 which hangs on the scaffolding pipe P, and the rear end of the fixed piece 11 is provided with an engaging portion 12 connected to the scaffolding foot F. 11) and the coupling portion 12 may be bent to the 'b' shape or connected flat or '1' shape.

The coupling part 12 may be coupled to one side of the scaffolding scaffold (F) by a bolt coupling or welding method, and in the drawing, the bolt coupling hole 12a formed through the left and right sides of the coupling part 12. The form in which this is provided is shown.

The fixing piece 11 is an annular shape having a locking portion 11A having an open lower side, and the scaffolding pipe P is inserted or separated through the lower opening of the locking portion 11A, and in the drawing, a circular scaffolding. Although an arc-shaped locking portion 11A is shown as an example of the embodiment installed in the pipe P, in the case of a square scaffolding pipe, a square-shaped locking portion is also possible.

The lower opening width of the locking portion 11A is formed to correspond to the outer diameter of the scaffolding pipe P to be fitted, and the lower opening of the locking portion 11A is closed (partly closed) by the clamp 20. The width of the opening is narrowed (clamping), so that the scaffold pipe P and the locking portion 11A are not separated,

In the state where the lower opening of the locking portion 11A is opened by the clamp 20, the width of the lower opening is widened again (clamping release), so that the scaffolding pipe P and the locking portion 11A are separated and the scaffolding for scaffolding ( F) can be dismantled.

In addition, a pivoting protrusion 13 protrudes from one side (right side in [A] of FIG. 2) of the fixing piece 11, and the clamp 20 pivots up and down about the pivoting protrusion 13. Make it flip.

The pivoting protrusion 13 has a head portion formed wider than the width of the sliding groove 21 of the clamp 20 to prevent the clamp 20 from being separated, and the pivoting protrusion 13 is welded to the fixing piece 11. It is coupled to or fixed to the other side is coupled in a rivet (13a) method.

The clamp 20 pivots up and down the pivoting protrusion 13 by an axis to allow the body 10 to be clamped to the outer circumferential surface of the scaffolding pipe P or the body 10 to the scaffolding pipe P. To be released by clamping at

In more detail, the body 10 is clamped to the scaffolding pipe P by sliding downwardly to close the opening of the locking portion 11A, or upwardly sliding to open the opening of the locking portion 11A. Thus, the body 10 is released from the scaffolding pipe (P).

The clamp 20 has a sliding groove 21 formed to penetrate both sides in a form corresponding to the sliding rotation path, and the rotation protrusion 13 is fitted into the sliding groove 21.

The locking means (L), so that the clamping release state, that is, the upward sliding rotation state of the clamp 20 is maintained,

A locking protrusion 22 protruding from the other side of the clamp 20 (the left side in [A] of FIG. 2),

A guide groove 14 provided at the fixing piece 11 to guide the up and down sliding rotation of the locking protrusion 22 by the locking protrusion 22 inserted therein;

It includes a locking groove (14a) is connected to the rear from the upper end of the guide groove (14) for the engaging projection 22 is walked.

The locking projection 22 is formed on the other side of the clamp 20 in contact with one side of the fixing piece 11,

When the clamp 20 pivots upward to open the lower opening of the engaging portion 11A, the clamp 20 pivots upward along the guide groove 14,

In the open state (in the clamping release state) of the engaging portion 11A, the pivoting projection 13 is turned to the rear side on the axis and supported by the locking groove 14a.

Therefore, in order to install and dismantle the scaffold scaffolding F, in the state where the clamp 20 is un-clamped, the locking protrusion 22 is fitted into the locking groove 14a, so that the clamp 20 slides downward due to its own weight. Since the rotation is limited, the installation and dismantling of the scaffold scaffold (F) can be easily and quickly performed.

In particular, when the engaging projection 22 of the clamp 20 is caught in the locking groove 14a, as in the present invention,

As the opening of the clamp 20 is maintained at all times, unless an operator intentionally rotates the clamp 20 forward to remove the locking projection 22 from the locking groove 14a.

Even if one worker releases the plurality of scaffold hangers C sequentially, the clamp 20 can be prevented from being clamped again due to vibration or shock generated during the work, and thus the scaffolding scaffold F Dismantling work is convenient.

In particular, as the present invention, when the clamp 20 is flipped to the rear side after the upward sliding rotation, since the clamp 20 does not invade the region of the catching portion 11A, the clamp 20 is the scaffold pipe P Can be prevented from being clamped again.

That is, as can be seen in Figs. 6 and 7, in the conventional scaffolding scaffolding device, when the clamp is slid upwardly, the upper end of the clamp invades into the engaging region, so that contact with the scaffolding pipe occurs. When the clamp is opened with the scaffold installed, the clamp returns to its original position due to contact with the scaffolding pipe.

As shown in FIG. 3, the present invention can solve the above problems because the clamp 20 does not invade the locking portion 11A while the clamp 20 is flipped to the rear side.

Further, in order to fix the scaffolding scaffolding F to the scaffolding pipe P, the catching protrusion 22 is removed from the locking groove 14a, and the catching protrusion 22 is in the state where the clamp 20 is slid downward. ) Is supported at the lower end of the guide groove 14, the fixing of the scaffolding scaffold (F) is maintained firmly,

In this case, due to the sliding pivot structure of the clamp 20, even if the pressure acts so that the scaffold scaffold F is lifted unless the operator artificially slides the clamp 20 upward counterclockwise, the locking projection ( Since the 22 presses the lower end of the guide groove 14, that is, the fixing piece 11 downward, the closed state of the clamp 20 is maintained, so that the separation of the scaffold scaffold F is prevented.

As shown in FIGS. 1 to 3, the locking groove 14a has an inner lower surface formed to be inclined downward from the front end to the rear end.

That is, the locking groove 14a is bent from the upper end of the guide groove 14 to the rear lower side.

Therefore, when the locking projection 22 is caught by the locking groove 14a, the locked state is maintained as long as the worker does not lift the clamp 20 out to the front side, thereby preventing the unintended return of the clamp 20. have.

Further, the locking groove 14a is formed such that the upper and lower widths between the inner upper surface and the inner lower surface become wider from the front end to the rear end.

That is, the overall shape of the locking groove 14a is formed to have a pseudo inverted triangle shape.

Therefore, as described above, when the locking projection 22 does not easily come out of the locking groove 14a, when the locking projection 22 hangs on the locking groove 14a or is removed from the locking groove 14a, the locking projection 22 ) Is not in contact with the fixing piece 11, it is convenient to use.

In addition, due to the inclined structure and shape of the locking groove 14a, the locking protrusion 22 is always positioned in the guide groove 14, unless an operator intentionally locks the locking protrusion 22 to the locking groove 14a. So that

For the installation of scaffolding scaffolding (F), if the scaffolding scaffolding device (C) is mounted on the scaffolding pipe (P),

When the scaffold pipe P is fitted to the engaging portion 11A, the lower end of the clamp 20 is hit, and the clamp 20 is automatically lifted and opened due to this pressure, and then the clamp 20 is opened by its own weight. It is closed while falling again, and installation of the scaffolding scaffold F becomes easy.

That is, when installing the scaffolding scaffold F to the scaffolding pipe P, after opening of the clamp 20 only by the coupling structure of the rotation protrusion 13 and the sliding groove 21, without using the locking means L, To allow automatic closing,

Only when the scaffold scaffolding F is dismantled from the scaffolding pipe P, it is more convenient to hold the locking projection 22 to the locking groove 14a so that the clamp 20 is kept open.

Subsequently, the clamp 20 protrudes on one side of the clamp 20, that is, on the opposite side on which the engaging protrusion 22 is formed, so that an operator can grip and slide the clamp 20. Is formed.

The reason why the clamp 20 is provided with the gripping protrusion 23 is that, as shown in FIG. 1, the space between the scaffolding pipe P and the scaffolding scaffold F is narrow, so that the operator can move the clamp 20. This is because it is difficult (especially for upward sliding rotation).

In particular, in the case of the present invention, it is necessary to hook the locking protrusion 22 to the locking groove 14a or lift it out of the locking groove 14a.

Unlike the conventional fixture, since the sliding groove 21 of the present invention is provided in a simple form corresponding to the sliding rotation path of the clamp 20, the angle adjustment of the clamp 20 should be preceded.

However, in a state in which the body 10 connected to the scaffold scaffold F is mounted on the scaffold pipe P, the space for moving the clamp 20 becomes narrow, so that the worker grips the clamp 20 directly with only a finger. It may be inconvenient to move, so that this problem can be solved through the gripping protrusions (23).

Next, a second embodiment of the present invention will be described with reference to FIGS. 4 and 5.

In the second embodiment of the present invention, the body 10 of the above configuration is connected in a pair of vertically symmetrical form, the clamp 20 and the locking means (L) is provided in the lower body (10) It is used to install the scaffold scaffolding F in the two-stage scaffolding pipe P. As shown in FIG.

That is, in addition to the configuration of the first embodiment, the upper body 10A, which is not provided with the clamp 20 and the locking means L, is vertically connected with the connecting portion 15 so as to be symmetrical with the lower body 10,

Scaffolding scaffolding device (C) is installed in such a way as to be sandwiched between scaffold pipes (P) arranged in two rows.

Therefore, if the scaffolding hanger device C for the scaffold is installed in the lower scaffolding pipe P, then another scaffolding pipe P is inserted into the engaging portion 11A of the upper body 10A and installed thereon.

The upper scaffolding pipe P is held while pressing the scaffolding hanger C for the lower side, thereby preventing the scaffolding scaffolding F from moving in the longitudinal direction of the scaffolding pipe P and installing it more safely. And use.

At this time, in the second embodiment, the scaffold scaffolding F is connected to the engaging portion 12 of the upper body 10A, and the scaffolding hanger C for the scaffolding is connected to the engaging portion 12 of the lower body 10. The frame for strengthening the bearing capacity is connected.

In the drawings, the connecting portion 15 is illustrated as being provided at the front end of each of the fixing pieces 11 of the upper and lower bodies 10A and 10, but the position and shape of the connecting portion 15 are not limited. That is, without the connecting portion 15, the upper, lower body (10A) 10 can be variously modified, such as directly connected.

In the above description of the present invention with reference to the accompanying drawings, scaffolding scaffolding device having a specific shape and structure was described mainly, but the present invention can be variously modified, changed and replaced by those skilled in the art, such modifications, changes and Substitutions should be construed as falling within the protection scope of the present invention.
