Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel frame building such as a building or a bridge, or a reinforcing bar assembly frame wound around the outside of the steel frame or the reinforcing bar forming the columns or beams of the reinforcing bar building.

[0002]

2. Description of the Related Art Conventionally, a reinforcing bar frame for assembling a reinforcing bar has a diameter of 10 mm or 13 mm with a different diameter (having a ring-shaped uneven surface) cut into appropriate sizes, and the cut rebars are supported by steel columns or beams. It was assembled vertically and horizontally around the skeleton and assembled into a skeleton surrounding the steel frame, and the intersections were bound by wires, strips, etc. to form a muscle frame.

[0003]

However, in this case, the field work is difficult and the strength is weak. In addition, the loop-shaped transverse bar surrounding the steel frame must be inserted in the steel frame before the steel frame is assembled, which is troublesome. The present invention eliminates such drawbacks, and a steel frame is preliminarily welded in a factory or the like by arc welding or spot welding to be assembled into a frame, and in some cases, a part of the frame can be horizontally folded as an axial bar. is there.

[Embodiment] A portion 1 for forming columns or beams such as steel frames and reinforcing bars
The four sides that surround the
Vertical stripes a₁, A₂... and horizontal stripe b₁, B₂・ ・
・ Each assembly is assembled by welding the intersections with the welding part 2.
A, B, C and D are constructed. Note that the assemblies A and C shown in FIG.
Vertical stripe a₁, A₂... a_nIs 5 and has vertical stripes a at both ends ₁，
a_nAnd the horizontal muscle horizontal muscle b₁, B₂End b of_YIs diagonal
Bend inward to create vertical stripes a at both ends₁, A_nWrapped around and melted
Contact. Vertical streaks a of the assemblies B and D₁, A₂... is three
There are no vertical streaks on both ends.

In each of these assemblies A, B, C and D, the end portions b _X of the transverse bars b ₁ , b ₂ ... Which extend laterally to the longitudinal direction of the steel frame 1 of the assemblies B and C are adjacent. Assembly A,
Vertical stripe a ₁ end and C, bent obliquely inwardly to engage a _n. The length of this end portion b _X is four times or more the diameter of the longitudinal stripe a ₁ and extends in the same oblique direction as the end portion b _Y , that is, is twisted, as shown in FIG. It should not interfere with the ends b _{Y of the} above-mentioned assemblies A and C. In this way, since the end portion b _X extends obliquely (twisted),
It does not interfere with the spot points when welding it to vertical stripe a _1, a _n. Further, the end portions b _{Y of the} lateral stripes b ₁ , b _2, ... That extend in the lateral direction of the adjacent assemblies A and C are also bent at a position adjacent to the end portion b _X. These ends b _X ,
Since a large number of b _Y are juxtaposed along the direction of the vertical stripes a ₁ and a _n , the end portions b _X and b _Y have long holes 5, 5 ...・ Mate.

As shown in FIGS. 6 (a) and 6 (b), when the end b _y and the end b _x vertically overlap each other, the long holes 5, 5, ...
Extend in the longitudinal direction of the long plate 4, but when the end b _Y and the end b _x overlap in the horizontal direction as shown in FIGS. 7A and 7B, the long holes 5, 5 ... It extends in the lateral direction of the plate 4.

Next, the assembly method of the present invention will be described. Place each assembly A, B, C, D on the side of the steel frame 1 surrounding it,
Ends b _X of the horizontal stripes b ₁ , b ₂ ... Of the assemblies B and C, ...
Is hooked on the vertical stripes a ₁ and a _n at the ends of the adjacent assemblies A and C, the muscle frame surrounding the steel frame 1 is assembled. Next, a mold (not shown) is assembled on the outer side of the assembled frame, and concrete is poured into the concrete frame 3 as shown by the dotted line in FIG.

When the present invention is applied to reinforced concrete having no steel frame, a reinforcing frame may be assembled on the outer side of the portion forming the bundle of reinforcing bars or other columns or beams instead of the steel frame.

FIG. 4 shows another embodiment of the present invention.
Two pairs of adjacent assemblies A, B in the above four assemblies A, B, C, D; transverse bar b of one assembly B, D of C, D
₁ and b ₂ ... Are connected so as to rotate with respect to the vertical stripes a ₁ at the ends of the other assemblies A and B. In this embodiment, since each pair of assemblies A, B; C, D are connected in a hinge shape, they can be folded in a flat shape, which is convenient for transportation and, when assembling the two assemblies, Since it is good, the connection work becomes easy.

In the above embodiment, two pairs of adjacent assemblies A, B in the above four assemblies A, B, C, D;
The lateral stripes b ₁ , b _2, ... Of C and D may be integrally formed into an L-shape. In this case, it cannot be folded in a flat shape, but since each pair is L-shaped, the assembly becomes easier.

FIG. 5 shows still another embodiment of the present invention, in which the horizontal stripes b ₁ and b _{2 of} the three adjacent assemblies A, B, C and D in the four assemblies A, B, C and D are adjacent to each other. ... are integrally formed in a U shape. In this case, the on-site assembly work is further facilitated, and the steel frame 1 and the like may be omitted.

As shown in FIG. 8, the ring 4a may be inserted in advance in the transverse line b ₁ and the ends b _X and b _Y may be locked to the ends b _X and b _Y by shifting the ring 4a. ..

As shown in FIG. 9, the hook 4b is fixed to the horizontal bar b ₁ , the end b _Y is inserted into the groove 6 of the hook 4b, and then the locking piece 7 is bent to lock the end b _Y. You may do it.

[0021]

As described above, according to the present invention, each assembly A, B,
C and D are arranged around a steel frame (or a bundle of muscles), and the end portions b _X of the horizontal bars b ₁ , b ₂ ... Of the assembly are simply hooked on the vertical bars of the end portions of the adjacent assembly. Therefore, on-site work is extremely easy, and work such as cutting and binding of reinforcing bars can be saved.Because each part is welded, it is stronger than the conventional bound frame and can save binding material. is there. Furthermore also folded at a position adjacent to the end b _X end b _Y of the adjacent assemblies A, horizontal stripes b ₁ extending transversely of the C, b ₂ ···, these end portions b _X, b _Since the long holes 5, 5 ... Of the long plate 4 are fitted in _Y , it is robust.
