Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hanging scaffold fixing metal fitting used in a construction site.

[0002]

[Prior Art]

 At construction sites, steel beams such as H-shaped steel and I-shaped steel are assembled, the reinforcing bars are wound around the steel beams, and the surroundings are solidified with concrete to form so-called beams. However, the suspended scaffolding is used for the purpose of the work and the following work.

Conventionally, a mounting piece for fixing the hanging scaffold is welded to the lower end surface of the steel frame beam on the hanging scaffold, and the hanging portion of the hanging scaffold is fixed to the through hole provided in the mounting piece. However, since this welding is troublesome, it is possible to attach or detach the flange of the steel beam by the attachment piece and the clamp portion, which has a bolt and nut slidably mounted on the attachment piece. In addition, the clamp part is slidably mounted on the mounting piece, the bolt is inserted into the through hole provided in the mounting piece and the clamp part, and the flange of the steel beam is clamped between the clamp parts by the movement of the clamp. Alternatively, there is a structure in which a hanging portion is provided so as to cross, a grip portion is provided at the tip of the hanging portion to fix the hanging portion to the flange of the steel frame beam, and a clip is locked at the crossing portion.

[0004]

[Problems to be solved by the device]

 However, there is no problem when mounting on steel beams, but when removing the suspension scaffold and removing the fixing bracket, in the case of the above configuration, in the former two cases, the clamp part is slid and mounted. When it is removed from the peas, it cannot be removed because it hits the reinforcing bars that connect the reinforcing bars that have already been installed around the steel beam.

Further, even in the case of the structure in which the suspension parts are crossed, the upper part having the grip part must be expanded, but it cannot be removed because it cannot be expanded because it hits the node or the connecting reinforcing bar. It had to be cut off or left attached to the metal fittings, which could cause problems with strength and economic loss.

Further, in the conventional hanging scaffold fixing bracket, a fixing bracket having a width corresponding to the width of the flange of the steel beam is required. For this reason, it was necessary to prepare many types of fixing fittings, which imposes a heavy financial burden and makes inventory management troublesome.

[0007]

[Means for solving problems]

 Therefore, in the present invention, the fixing metal fittings can be removed without being disturbed by the presence of the reinforcing bars and connecting reinforcing bars, and can be used according to the width of each type of flange. It is an idea to propose a hanging scaffolding metal fitting with great practical effects such as preparing only a small number, economical advantage, and easy inventory management. An appropriate number of through holes are drilled in the mounting base. At the same time, the two slide plates that have through holes corresponding to the through holes are fixed to the desired position of the mounting base with bolts that insert the through holes, while side plates are provided on the outer sides of both slide plates. The characteristic feature is that a hook-shaped plate is fastened to the side plate with a bolt which is inserted into both insertion holes, and a fastening fixing portion is provided on the hook-shaped plate-shaped portion.

The side plate 8 is formed to be higher than the slide plate 3 , and a through hole 10 is formed in the side plate 8. The through hole 11 formed in the side plate 5 is inserted with a bolt 12 and tightened with a nut 13. It seems to polymerize. Reference numeral 14 is a bolt, and a nut 15 and a through hole 16 provided in the hook-shaped plate 9 are screwed through to form a tightening and fixing portion 17 . In the figure, 18 is a scaffold, 19 is a suspended portion, 20 is a reinforcing bar, 21 is a connecting reinforcing bar, and 22 is concrete. The through holes 2 provided in the mounting base 1 and the through holes 4 provided in the slide plate 3 may be separate through holes, or one or both of them may be formed as lateral long holes.

Next, the use thereof will be described. The slide plates 3 and 3 are superposed on the mounting base 1 , and the positions are slid to attach the width formed by the mounting base 1 and the slide plates 3 and 3. The width of the flange 26 is made substantially the same. Therefore, select the through holes 2, 2, ..., through holes 4, 4, ... of both the mounting base 1 and the slide plates 3 , 3 , and insert the bolts 23, 23, ... into the nuts 24, 24, .... Tighten. The mounting base 1 provided with the slide plates 3 and 3 thus formed is brought to the lower surface of the flange 26 of the steel beam 25 . Then, against the locking plate 7, 7 from both sides of the flange 26, the side plate 5 of the sliding plate 3 combined side plate 8 of the retaining plate 7, through-holes 11 of both the bolts 12, nuts 13 are inserted in the 10 Then, the flange 26 is clamped between the side plates 8 and 8.

Next, by screwing the bolt 14 into the nut 15, the top plate 6 or the flange 26 is vertically fixed between the mounting base 1 and the slide plates 3 and 3 when the top plate 6 is not provided. . Of the through holes 2, 2, ..., through holes 4, 4, ... of the mounting base 1 and the slide plates 3 , 3 , the through holes 2, 2 and the through holes 4, 4 in which the bolts 23 are not inserted are appropriately selected. The suspension parts 19 and 19 are fixed by the process, and the scaffold 18 is suspended and fixed to the flange 26.

[0012] In removal of the scaffold 18, the hanging portion mounting base 1 a scaffold 18 by 19, 19 and the slide plate 3, 3 from removal, followed by removing the bolts 12, 12, mounting base 1 and the slide plate 3, 3 Remove. This removal is performed without moving to the left or right, only by moving it downward, and without hitting the connecting rebar 21.
