Abstract

PROBLEM TO BE SOLVED: To improve workability by fixing a hook to the respective outer end parts of an inner pipe and an outer pipe which are inserted to be elongated and contracted for locking the pipes to wale materials for assembling a batten from above. SOLUTION: A scaffold foundation metallic part comprises an inner pipe 1 having a hook 2 provided on one side end part, and an outer pipe 3 which is externally fitted to the outside of the pipe 1 to be elongated and contracted and has a hook 4 provided on one side end part. Subsequently, in the case of constructing an opening part of an elevator chamber, for example, a wall formwork is erected, and longitudinal and lateral battens are assembled by formwork clamps. Next, above the opening part, the hooks 2, 4 of the scaffold foundation metallic tool which is controlled to a required length by elongating and contracting the pipes 1, 3 are put on the lateral batten and constructed. Further, a scaffolding plate or the like is placed on the scaffold foundation metallic tool to be used as working scaffold and a fall preventive curing. Thus, construction can be accomplished simply without much labor, temporary material and mechanical equipment.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction in which an opening of an elevator room or an opening of a slab at a construction site is hung from above a horizontal flap material used for assembling a wall form or the like. The present invention relates to a scaffold foundation metal fitting that can be used as a work scaffold.

[0002]

2. Description of the Related Art Conventionally, when constructing an opening of an elevator room or a slab at a construction site of this kind, a means for assembling a wall formwork or the like on a horizontal fluttering material to be used as a foundation for a working scaffold has been proposed. , A method of building a scaffold from the lower floor was being implemented.

[0003]

In the above conventional method,
A large number of temporary materials (scaffolding assembly members, equipments) are required, which is economically disadvantageous, work efficiency is reduced, construction time is required, and safety is not sufficient.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to construct a foundation for a working scaffold by installing a wall formwork in an opening on a horizontal fluttering material. However, it is an object of the present invention to provide a practical scaffolding metal fitting for a construction opening, which can be implemented simply, reasonably, and safely, and can save a lot of temporary materials and equipment, and is economically advantageous. .

[0005] As means for this, hook metal fittings are fixed to the outer ends of the inner pipe and the outer pipe, which are extendably inserted, and which are engaged with the horizontal butter material for assembling a wall form or the like from above. It is characterized by becoming.

[0006] With the above structure, it is possible to easily and surely secure a work scaffold by erection on a horizontal fluttering material used for assembling a wall form or the like at the opening, and it is possible to reduce labor of temporary materials and equipment, and to secure safety. Thus, a working scaffold which is economically advantageous is constructed, and the above-mentioned object is solved and the above-mentioned object is achieved.

[0007]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view of a scaffolding base metal fitting for a construction opening according to an embodiment of the present invention. The reference numeral 1 shown in the figure denotes an inner pipe, which is provided with a hook fitting 2 having a substantially 7-shaped front face fixed to one end. Reference numeral 3 denotes an outer pipe which is inserted into the outer side of the inner pipe 1 so as to be extendable and contractable, and has a hook fitting 4 having a substantially 7-shaped front face fixed to one end.

In the drawing, 5.6 is the hook fittings 2 and 4.
The through-holes are formed on the same axis by penetrating the side plate, and are used to insert retaining pins, bolts and the like (not shown). Reference numeral 7 denotes a fixing bolt for fixing the inner pipe 1 and the outer pipe 3 at a required length.

A method for using a scaffolding base metal fitting for a construction opening according to an embodiment of the present invention will be described with reference to FIG. For example, when constructing the opening of the elevator room A, a wall formwork P and the like are built, and a vertical flutter material B and a horizontal flutter material C are assembled with a formwork fastening fitting G. further,
Above the opening, the hook fittings 2 and 4 fixed to the outer ends are adjusted from the upper side of the horizontal fluttering material C to the required length by the expansion and contraction of the inner pipe 1 and the outer pipe 3, respectively. Hang and erection.

[0010] Thereafter, if necessary, and in order to further improve safety, it is also possible to easily insert pins or bolts into through holes provided in the side plates of the hook fittings 2 and 4 on both sides and stop them. . A scaffold D or a plywood formwork or the like is placed on the scaffold base metal fittings assembled in this manner, whereby a work scaffold for concrete placing work around a wall or a pillar can be constructed. As well as a working scaffold, it is intended to prevent falling accidents by curing.

[0011]

As described above in detail, according to the scaffolding base metal fittings for the opening for construction of the present invention, a lot of labor, temporary materials and equipment are required, for example, assembling the scaffold from the lower floor as in the prior art. Instead, it is possible to construct a scaffolding base metal fitting for a practically useful construction opening, for example, it can be installed safely and economically with the simple work of hanging and erection from the horizontal fluttering material to assemble wall forms etc. Obtainable.
