Description

[Detailed description of the invention] This invention relates to a device for effectively, accurately and reliably assembling reinforcing bars and formwork for walls and columns when constructing large structures. .

Conventionally, large structures (e.g. wall thickness 300mm to 1500mm,
When constructing a building (approximately 6 meters high), the reinforcing bars used are of large diameter and the formwork is made of large panels, which requires a lot of labor and expense to assemble the reinforcing bars and formwork.

In addition, for the construction, as shown in Figure 6, scaffold frames A and A are assembled on both the inside and outside of the wall, etc., and a single connecting material B- such as reinforcing bar is erected between the scaffold frames A and A. This is used to support and assemble the head of the reinforcing bar C of the wall, etc.

Furthermore, a formwork P is assembled on the outside thereof. After the concrete is poured and cured, the surrounding concrete is scooped and cut to treat the binder B, and the mortar is repaired.

For this reason, it not only requires a lot of labor for post-processing, but also has drawbacks such as impairing the quality of the building and being uneconomical and unreasonable.

This idea was created in view of the above-mentioned conventional problems, and its purpose was to streamline the assembly of reinforcing bars and formwork for walls or columns of large structures, and maintain the spacing between reinforcing bars and formwork. and easy to fix,
It is an object of the present invention to provide an apparatus for assembling reinforcing bars and formwork for large structures, which has excellent effects such as high accuracy.

In order to achieve the above object, this invention provides female threaded portions at both ends, and provides the female threaded portion at least one end of the female threaded portion to be movable forward and backward along the horizontal axis.
A connecting rod whose both ends are adjustable between walls or column forms and configured to support reinforcing bars;
It consists of a wall connecting fitting provided with a telescoping rod that is telescopically connected along the axis of the support rod, which has a male threaded portion at one end so as to be removably screwed into the female threaded portions at both ends of the connecting rod. It is characterized by

Hereinafter, embodiments of this invention will be described in detail based on the drawings.

FIG. 1 is a partially cutaway front view of an embodiment of a connecting rod 1 according to this invention, and FIG. 2 is a partially cutaway front view of an embodiment of a wall connecting fitting 9.

The connecting rod 1 has a male threaded shaft 3 protruding from one end of a deformed steel bar 2 of an appropriate thickness, and a female threaded portion 4 is integrally provided along the axis of the other end. Locking nut 5 and adjustment female screw part 6
are screwed together so that they can move forward and backward.

Reference numerals 7 and 8 refer to formwork receiving pieces fitted to the mouth ends of the adjusting female threaded part 6 at one end and the female threaded part 4 at the other end, which are molded from synthetic resin or the like and have a through hole in the center of the tip leading to the female threaded hole. 7a and 8a are provided respectively.

The wall connecting fitting 9 is connected to the female threaded portion 4 of the connecting rod 1.
and to be removably screwed into the adjustment female screw part 6,
A male threaded portion 10 is fixed to one end of a pipe body of an appropriate length, and a support rod 12 is provided with connection holes 11 at equal intervals from the outer periphery in a direction orthogonal to the axis, and is loosely inserted along the outer periphery of the support rod 12. The pipe body has a connecting hole 13 near one end that matches the connecting hole 11- of the support rod 12, and a telescopic rod 15 with a stopper 14 integrally provided at the other end.
and 13 to pass through the fixing bolt 16 and nut 1.
7, which are extendably connected.

The assembly device of one embodiment with the above structure has a third
As shown in Figures and Figure 4, (a) Assemble the scaffolding frame A with the desired spacing inside and outside the wall to be constructed.

(b) Wall connecting fittings 9 are attached to one (right side) scaffolding frame A,
9 with clamp fitting C.

C. Pass the formwork P1 on one side through the male threaded part 10 at the tip of the wall connecting fittings 9, 9, and connect the connecting rod 1,
Attach by screwing together the female threaded parts 4, 4 of 1.

(d) Female threaded part 6 for adjustment at the other end of the connecting rods 1, 1;
6 through the opposite formwork P2 (left side)
Screw in the wall connecting fittings 9, 9, and attach the ends to the scaffolding frame A1 on the opposite side from the clamping fitting C to connect.

E Horizontal strip B1 of the wall on one side above the connecting rods 1 and 1,
B1 is fixed and the vertical stripes B2- are further assembled at a predetermined pitch.

F. Along this vertical strip B2-, other horizontal strips B1- are also assembled at a predetermined pitch.

G. Assemble the horizontal reinforcements B1'- and B2'- on the opposite side of the wall in the same manner as described above.

H. Undo the wall joints 9, 9- that connect scaffolding frames A and A1 on both sides.

(i) The spacing between the formworks is adjusted by the adjusting female screw parts 6, 6 and fixed by the locking nuts 5, 5, and the predetermined positions of the wall reinforcing bars are connected to the connecting rods 1, 1 to make them strong.

Note that the procedure for assembling the reinforcing bars and formwork is not limited to the above-mentioned method as long as it can improve the efficiency and accuracy of reinforcement work and formwork assembly work.

In addition, concrete is poured into the formwork, and after curing, the wall connecting fittings 9- on both sides are removed, and the formworks P1 and P
2 was dismantled, and the through holes 7a, 7a, 8a, 8a of the formwork receivers 7, 7, 8, 8 were exposed on the concrete surface.
and caulking inside the female threads 4, 4, 6, 6, or a synthetic resin cap (not shown).
You can fill it up and finish it easily.

FIG. 5 is a partial sectional view showing another embodiment of the connecting rod 21 according to this invention, in which male threaded shafts 23, 23 are symmetrically provided at both ends of the steel bar 22, and the male threaded shafts 23, 23 of this On the other hand, the locking nut 25,2
5 and adjusting female screw portions 26, 26 are screwed together so as to be freely retractable.

Even in this case, the same effects as in the previous embodiment can be achieved.

Furthermore, the structure of the wall connecting fittings is not limited to the previous embodiment, and may be any other structure that utilizes a pipe to which a scaffolding board can be easily attached on the shaft of the fitting.

According to the device for assembling reinforcing bars and formwork for large structures of this invention as described above, it is possible to easily, precisely, and reliably maintain and fix the spacing between reinforcing bars in walls or columns, and between formworks, etc., for large structures. It has a remarkable effect on improving quality when constructing things.

In addition, post-treatment of the joints after concrete pouring and curing is simple and easy, and has great practical effects.
