Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reinforcing metal fitting for strengthening the corners of an opening 1].

Conventionally, for example, the method of reinforcing an opening in an exterior wall involves arranging vertical, horizontal, and diagonal reinforcement around this opening to reinforce it, and then arranging welded wire mesh to prevent cracks. Met. However, since both the reinforcing reinforcing bars and the welded wire mesh are placed separately on site, reinforcing the openings takes time and effort, and there is still room for improvement in the reinforcing effect.

The present invention reduces the number of steps involved in on-site reinforcement, requires less time and effort in construction compared to conventional examples, and can be constructed with high precision.
Furthermore, we propose a reinforcing metal fitting for the corner of the opening that can enhance the reinforcing effect.

Embodiments of the present invention will be described below based on the drawings.

In FIGS. 1 to 4, the reinforcing plate 1 is formed in an L shape and is installed, for example, at a corner of an opening W'a provided in an outer wall W. L-shaped anchoring bars 2.2 are welded to the inner surfaces of the horizontal and vertical parts of the reinforcing plate 1, and these anchoring bars enhance the anchoring effect as well as reinforcing the reinforcing plate. Further, on each outer surface of the horizontal and vertical parts of the reinforcing plate 1, reinforcing anchor bars 3 and 404 of a predetermined length are bent into a U shape, for example. ff1 (is welded), and each anchor bar is arranged perpendicular to the horizontal and vertical parts where it is attached.The bar between the tips of both anchor bars 3 and 4 is placed first. The reinforcing metal fittings are connected by connecting bars 5 and formed into a triangular shape as a whole to strengthen the reinforcing metal fittings.In order to increase this reinforcing effect, a triangular-shaped welded wire mesh 6 is provided across both anchor bars 3 and 4. Therefore, the reinforcing plate 2, anchor bars 3.4, and welded wire mesh 6 were made into a unit.
It constitutes an article.

Next, the installation of this reinforcing metal fitting will be explained.

First, the reinforcing plate 1 of the reinforcing hook tool is installed at the corner of the opening Wa of the outer end W, and then anchor bars 3.4 are attached at multiple locations (for example, 4 locations A, B, C, and D in the drawing) in advance. (Vertical reinforcements 7 and horizontal reinforcements 8 are arranged around the part as shown in chain lines)
Connect it with a wire and fix the reinforcing metal fittings.

By attaching the reinforcing metal fittings to the corners of the opening Wa as described above, the drying shrinkage of the concrete is prevented by the reinforcing plate 1, further suppressed by the anchoring bars 2, and the tension in the vertical, horizontal and diagonal directions is prevented. The anchor bars 3.4 provide resistance, and the net 6 on the periphery provides resistance, and a composite and synergistic effect occurs due to the unitization. In this example, - and 4a are attached to the horizontal and vertical parts of the reinforcing plate 1, respectively. The ends of the anchor bars 3 and 4.3a and 4a are connected by connecting bars 5 and 5a, and a welded wire mesh 6 is stretched between the anchor bars 3 and 4.

A welded wire mesh 6a is stretched over the anchor reinforcements 3a and 4a, facing the welded wire mesh. The reinforcing metal fitting in this example is suitable when the outer wall W is thick, and as explained above, according to the present invention, it is a reinforcing plate.

It is possible to integrate the reinforcing anchor bar and the welded wire mesh and attach it to the corner of the opening, so it is easy to remove and install, saving time and effort. Since a composite and synergistic effect can be expected due to integration, the reinforcing effect can be enhanced compared to the conventional example.
