Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a stirrup bar, and more particularly to a stirrup bar that can be easily attached so as to bundle around the main bar arranged along the ground. .

(Prior art) As a construction method to protect the slope, multiple main bars are arranged vertically and horizontally along the ground of the slope, and concrete is sprayed along this to construct a lattice structure on the slope. There is a construction method that prevents the slope from collapsing. The periphery of the plurality of main muscles a is to be bundled by stirrup muscles b as shown in FIG.

(Problems to be solved by the present invention) The stirrup muscle b is formed in a U shape, and its open end is bent in a hook shape to be hooked on the lower main bar, but the lower main bar is the ground. It was very close to the mountain and it was extremely difficult to hook them. Especially when using a prefabricated formwork unit c in which a weir board and this spacer are integrated in advance, first place the prefabricated formwork unit c on the ground, arrange the main reinforcement a, and then attach the stirrup reinforcement b. It was impossible to put the stirrup streak b in the narrow space and hook it.

The present invention has been made in order to solve the above problems, and an object thereof is to provide a stirrup streak having extremely good workability.

(Means for Solving the Problems) The stirrup muscle according to the present invention is formed in a U shape by the upper muscle portion and the left and right side muscle portions, and is perpendicular to the side muscle portion from each lower end of the left and right side muscle portions. In addition, the lower streak portions are formed in the same direction so as to be substantially parallel to each other. At this time, the inferior muscle portions may be formed so that the width thereof gradually becomes narrower toward the tip.

Further, the inferior streak portion may be formed at right angles to the lateral streak portion and in opposite directions so that the extension lines thereof are parallel to each other. At this time, both lower muscle portions may have lines parallel to them intersecting the upper muscle portions at an acute angle.

The lower muscle portion of the stirrup muscle may be tied to the main muscle near the natural ground.

(Action) Attach the stirrup muscle so that it covers the main muscle. By making the widths of both inferior muscles narrower toward the tip, the inferior muscles can be hooked below the main muscles. Since the lower reinforcement is not hook-shaped, the work is easy even if the main reinforcement is close to the natural ground or the space between the dam plate and the main reinforcement is small.

As a result of a shear test and a single adhesion test, this lower bar processed parallel to the main bar is effective as there is no difference in the shear strength from the hook protruding inward as in the past. It has been confirmed.

(Embodiment) The present invention will be described below based on an embodiment shown in the drawings.

In the figure, A is a stirrup muscle according to the present invention, which is formed in a U-shape by an upper muscle portion 1 and left and right muscle portions 2 and 2 extending in parallel from the left and right sides of the upper muscle portion 1. A lower streak section 3.3 is formed at each lower end of the left right streak section 2.2. The inferior muscle part 3.3 is at a right angle to the lateral muscle part 2.2,
Moreover, they project in the same direction so as to be substantially parallel to each other.
(FIG. 1) FIG. 2 shows a case where the width between the lower streaks 3 is gradually reduced.

Also, the lower muscular portion 3.3 is perpendicular to the lateral muscular portion 2.2,
Further, the extension lines may be formed in opposite directions so that they are parallel to each other. (FIG. 5) A case where the stirrup muscle A as described above is used for constructing a structure for slope reinforcement will be described. In FIG. 2, reference numeral 4 is a main bar, and the main bar 4 is covered with the side bar portions 2, 2 of the stirrup bar A so as to bundle the circumference of the main bar 4 toward the ground. At this time, the inferior muscle part 3.3
Is almost parallel along the main line 4, 4 closer to the ground. The lower streak portion 3/3 is hooked on the lower side of the main streak portion 4/4. With this, a plurality of main bars 4 can be integrated.

The lower bar portions 2.2 may be bound to the main bars 4.4, or may be integrated with the main bars 4.4 by welding.

Reference numeral 5.5 is a weir plate, and a net material such as expanded metal can be used.

(Effect of the device) The stirrup muscle according to the present invention has the above-described configuration, and since the lower muscle portion is processed in parallel with the main muscle, a hook-shaped hooking portion protruding inward as in the past is used. Since it does not have it, even if the main bar and the ground are extremely close to each other or the gap between the main bar and the dam plate is small, the mounting becomes extremely easy.
