2. Description of the Related Art Conventionally, when supporting heavy-load concrete slabs, prefabricated balconies and slabs, scaffolding boards for passages, etc., at construction sites of construction, etc., a jack base is positioned with a few insertion pipes at the bottom end. Support a suitable number of pipe supports connected by support pins or support bolts so that the bracket is located at the uppermost end, or have a jack base at the lower end and a bracket at the upper end. It was supported by several frame braces between the frames and a frame support that erected a cloth frame. In addition, a connecting frame in which columns having fitting recesses or fitting protrusions are provided on both ends of the connecting rod, and a frame body in which two vertical single pipes fitted to this are connected by a horizontal member. Most of them were combined.

[0003]

[Problems to be solved by the invention] However, in the former case, since the heights of the plug-in pipe and the building frame are set in advance, one type of pipe support or frame support requires concrete slabs, prefabricated balconies or slabs, and corridors. Not only is it not possible to support all heights of scaffolding boards, etc., but it also requires accessory pins such as support pins and bolts.
I could not do quick assembly work. In the latter case, the operation of connecting with the stack is troublesome.

In view of the above-mentioned problems, the foundation frame supporting the jack base in the lower portion, concrete slabs, prefabricated balconies and slabs, scaffolding boards for passages, etc. are supported at any height in the middle. It is possible to quickly assemble a stacking body with different heights that are stacked alternately in a frame shape and an uppermost frame that supports a receiving metal fitting on the upper part, without requiring accessory parts such as support pins and support bolts. A stackable temporary support frame was devised, and the present invention proposes that the uppermost bracket and the lowermost jack of the stackable temporary support frame are placed in places where the normal foundation frame and the top frame cannot be used for some reason. (EN) An end supporter for a stacking type temporary frame that not only allows the base to be supported horizontally and simply but surely, but can also be very easily connected to the stacking body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

The end support 1 of the stacking type temporary supporting frame A of the present invention is, as shown in FIGS. 1 to 5, a stacking type temporary supporting frame A.
Of the uppermost bracket B and the lowermost jack base C, a connecting rod 3 is installed between a pair of supporting rods 2 of the same length as appropriate, and the supporting rod is point-symmetrical about the connecting rod 3. The joint 4 for connecting the stacked body D is provided only on one side of the end position of 2.

That is, as shown in FIG. 1, 20 mm to 50 mm
A pair of parallel pipes 2 having the same length and having a round shape are parallel to each other between one end portions (upper end portions in the drawing) of the pair, and are engaged with each other at both ends E. Locking claws F and locking pins G for locking. A square pipe-shaped connecting rod 3 with a stop hole 5 is erected by welding means or the like, and the other end (lower end in the figure) of one of the columns 2 is in the middle of the stacking type temporary support frame A. The tubular joint 4 for connecting the stacked body D is formed to be attached by welding means or the like.

Further, as shown in FIG. 2, the joint 4 has an inner diameter at the base end portion substantially the same as the outer diameter of the support column 2 and an inner diameter on the tip end side of the support column H of the stack D. The column H of the stacking body D is attached to the tip of the tubular joint body 6 that is slightly larger than the diameter.
A guide portion 7 for connecting and guiding is provided so as to be expanded in a trumpet shape toward the tip end, and a bulging portion 8 for reinforcement is provided at a substantially central portion of the joint body 6 in the vertical direction. A proper number of through holes 9 for water / air bleeding and confirmation of connection between the stanchions 2 and H are formed at appropriate intervals in the vicinity of the front end portion and the base end portion. According to this joint 4, not only can the pillar H of the stacked body D be easily inserted while being guided along the guide portion 7 and the end faces of the pillars 2 and H can be abutted to each other for reliable connection, but also each penetration Combined with the fact that water or air can escape from the hole 9 and the connection state of the columns 2 and H can be confirmed from the through hole 9 near the tip, the connection operation with the column H of the stack D is easier. It can also prevent the occurrence of rust etc.,
Further, the bulging portion 8 can remarkably increase the vertical reinforcement.

Next, the usage of the end support 1 of the present invention will be described. As shown in FIGS. 3 to 5, concrete slabs with heavy loads, prefabricated balconies and slabs, and passageways are used at construction sites of construction. When supporting a scaffolding board or the like, first, stacking bodies D having different heights in the middle of the stacking type temporary support frame A are alternately stacked in a frame shape, and the stacking bodies D facing each other at the lowest position are stacked. In the lower part of the column H, the upper part of the column 2 of the end support 1 of the present invention in which the joint 4 is directed upward is inserted from below through the mutual joints I and 4, and is connected to each end support. The jack base C is inserted into the lower part of the column 2 of 1 to support it horizontally.
