[0038] The handcuff-type clamp according to the present invention and the shelf support to which the same is applied are,

[0039] It is applied to a scaffolding structure consisting of a plurality of vertical members (100) and horizontal members (200) connecting each vertical member (100).

[0040] A height setting fastener (2) having a tubular body (22) that is screw-coupled to a screw portion (110) formed on the outer surface of the vertical member (100), and a plurality of brackets (24) formed on the outer circumference of the tubular body (22);

[0041] A shelf material (4) that is horizontally arranged with a connecting part (42) formed at one end and coupled to the bracket (24) of the height setting fastener (2);

[0042] A support member (6) comprising a vertical support bar (62) vertically connected to one side of the shelf member (4) and arranged parallel to the vertical member (100), and an inclined bar (63) connecting the shelf member (4) and the vertical support bar (62); and

[0043] It includes a fastening member (7) that is connected at one end to the support member (6) and coupled to the outer surface of the vertical member (100).

[0045] The above support member (6) is composed of a horizontal support bar (64) that is attached to the middle and lower parts of the height setting fastener (2) respectively and is in close contact with the outer surface of the vertical member (100).

[0047] The above fastening member (7) is connected to the horizontal support bar (64), and

[0048] It is formed in a curved shape to correspond to the curvature of the outer surface of the above vertical member (100), and

[0049] First, a hinge shaft (718) is connected to each of the first and second clamping bodies (71, 72) that are respectively in close contact with both sides of the outer surface of the vertical member (100);

[0050] It is configured to include a fixing member (74) that is coupled through to the other end of the first and second clamping bodies (71, 72).

[0052] The first clamping body (71) is made of an arc-shaped metal plate, and a first hinge part (710) having a hinge hole (7102) is formed at one end, and a locking part (712) made of an upper plate (7121) and a base (7122) is formed at the other end in an L-shape.

[0053] An insertion slot (714) with both ends open is formed on the inner side of the catch (712). An end of the second clamping body (72) is inserted through the insertion slot (714).

[0054] And a first locking hole (715, 715') is formed in each of the top plate of the locking member (712) and the first clamping body (71).

[0055] A fixing member (74) is connected by passing through the first locking hole (715, 715') of the locking member (712).

[0057] A stopper (716) is formed on one side of the catch (712) on the upper surface of the first clamping body (71).

[0058] The stopper (716) is formed on the outer side of the first locking hole (715') at a predetermined distance.

[0059] Therefore, the stopper (716) catches the end of the second clamping body (72) that is coupled to the insertion slot (714) and blocks it from entering further, thereby allowing the proper coupling position to be maintained.

[0060] That is, the stopper (716) can restrict the hinge movement of the first clamping body (71) and the second clamping body (72). Although FIG. 3 shows the stopper (716) formed on the upper surface of the first clamping body (71), the stopper may also be formed on the lower surface of the second clamping body (72).

[0062] The second clamping body (72) is made of an arc-shaped metal plate, and a second hinge part (720) having a hinge hole (7201) is formed at one end, and a fastener (722) that is inserted into the fitting slot (714) is formed at the other end.

[0063] The above fastener (722) is formed with a second locking hole (7220).

[0065] The first hinge portion (710) of the first clamping body (71) is formed with a step downward, and the second hinge portion (720) of the second clamping body (72) is formed with a step upward.

[0067] A plurality of uneven grooves (717, 727) are formed in the circumferential direction on the inner surface of the first clamping body (71) or the second clamping body (72). By forming a plurality of uneven grooves (717, 727), the fixing force can be enhanced so that the protruding inner surface can be firmly fixed to the outer surface of the vertical member (100) by friction.

[0069] The first clamping body (71) and the second clamping body (72) are each rotated using the first hinge part (710) and the second hinge part (720) as hinge axes (718) to wrap around the outer surface of the vertical member (100), and then a fixing member (74) is connected by passing through the first locking hole (715) and the second locking hole (7220).

[0070] The first hinge portion (710) of the first clamping body (71) is formed with a step downward, and the second hinge portion (720) of the second clamping body (72) is formed with a step upward, so the first hinge portion (710) and the second hinge portion (720) overlap, and the first clamping body (71) and the second clamping body (72) can have substantially the same height (see FIG. 5).

[0071] Meanwhile, the fastening member according to another embodiment is formed in a curved shape to match the curvature of the outer surface of the vertical member (100) as shown in FIG. 6, and is composed of first and second clamping bodies (71, 72) that are respectively attached to both sides of the outer surface of the vertical member (100) with a hinge shaft (718) connected to one end, and a horizontal support bar (64) is formed on the side of the second clamping body (72) and is formed in the lateral direction of the catch (712).

[0072] As shown in FIG. 6, a fixing member (74) is coupled facing the hinge axis (718), and a horizontal support bar (64) is formed at a position close to the hinge axis (718).

[0073] Therefore, the catch (712) is formed at an oblique position on the side of the horizontal support bar (64), so that it does not interfere with other horizontal members (200) or vertical members (100).

[0075] Meanwhile, the above shelf material (4) is made of a tubular body of a predetermined length, and is joined by hooks (52) on both sides of the footrest (5).

[0076] Referring to FIGS. 1 and 2, the shelf member (4) has a ball joint receiving portion (44) formed in a trumpet shape so that a ball joint (102') formed at the end of another vertical member (100') is joined thereto.

[0077] And the connecting part (42) formed at the other end of the shelf material (4) has an opening formed on one side into which the bracket (24) of the height setting fastener (2) is fitted, and cut grooves (4221) formed on both sides, and includes supporting pieces (422) formed symmetrically on the upper and lower sides.

[0078] The above-mentioned support members (422) have pin coupling holes (4222) formed through them, and the structure includes a fixing member (424) that is fitted into the pin coupling holes (4222) on both sides and is coupled through to the bracket (24).

[0079] Therefore, after the bracket (24) is fitted into the opening of the joint part (42), the fixing member (424) is fitted and fixed.

[0080] Here, an additional portion (246) may be formed on the outer surface of the bracket (24).

[0081] The additional part (246) is inserted into the interior of the joint part (42) and serves to maintain an appropriate gap so that the through hole (240) of the bracket (24) and the pin joint hole (4222) of the support piece (422) can be aligned.

[0083] Meanwhile, it is configured to include a receiving portion (150) formed on the outer surface of the vertical member (100) and having a receiving hole (152) formed inside, and a distance setting portion (8) that adjusts the horizontal level of the shelf member (4) by adjusting the distance between the vertical member (100) and the receiving portion (150).

[0084] A receiving portion (150) is welded to the outer surface of a vertical member (100) or a longitudinal rail groove (130) is formed on the outer surface of a vertical member (100) so that it can be moved up and down, and the receiving portion (150) can be connected to the rail groove (130) and moved up and down.

[0085] A fixing means is included to temporarily fix the receiving portion (150).

[0086] The fixing means comprises a plurality of fixing grooves (132) formed longitudinally on the inner surface of the rail groove (130), a ball (154) protruding from one outer surface of the receiving portion (150) in correspondence with the fixing means, and a spring (155) embedded in the outer surface of the receiving portion (150) to elastically support the ball (154).

[0088] The above distance setting part (8) is formed at the end of the horizontal support bar (64) with a predetermined length and includes a fitting piece (82) that is inserted into the receiving slot (152) and has a rack gear (822) formed on its outer surface, and a fixing member (1522) that is formed on the inner surface of the receiving slot (152) and is fitted and coupled to the rack gear (822). The fixing member (1522) is coupled to an embedded groove formed on the inner surface of the receiving slot (152) and is coupled to a spring (1524) inserted into the embedded groove to have elastic force.

[0090] Therefore, when the horizontal support bar (64) is pulled, the fitting piece (82) is pulled out of the receiving slot (152), so the inclined bar (63) and shelf material (4) move together in one direction and the angle can be adjusted upward.

[0091] Conversely, if the horizontal support bar (64) is pushed so that the fitting piece (82) is inserted into the receiving slot (152), the inclined bar (63) and shelf material (4) move together in the other direction, and the angle can be adjusted downward.

[0092] By using this distance setting part (8), the horizontal state of the shelf material (4) can be adjusted by adjusting the spacing, allowing the worker or equipment to be stably placed.

[0094] Although embodiments of the present invention have been described in more detail with reference to the attached drawings, the present invention is not necessarily limited to these embodiments and may be modified in various ways within the scope of the technical spirit of the present invention. Accordingly, the embodiments disclosed in the present invention are intended to explain, not limit, the technical spirit of the present invention, and the scope of the technical spirit of the present invention is not limited by these embodiments. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. The scope of protection of the present invention shall be interpreted by the claims below, and all technical spirits within an equivalent scope shall be interpreted as being included within the scope of rights of the present invention.
