いのが実情である。For example, according to the earthquake surveys conducted so far,
It has been reported that in a reinforced concrete building, the structure with earthquake-resistant walls is superior to the structure with only columns and beams in terms of seismic performance and is less damaged by the earthquake. However, it has been pointed out from the results of experiments on some earthquake-resistant wall structures that shear failure of the wall plates and side columns of the earthquake-resistant walls may cause a sharp decrease in yield strength and lead to brittle fracture. .. Regarding the exfoliation and collapse of concrete, which is a factor of such brittle fracture, the fact is that studies on means for preventing this have not been made so much.

とを目的としている。As for the conventional seismic wall consisting of a wall body using a large amount of reinforcing bars, in the case of a wall plate having a large found area, the wall reinforcing bars are arranged and solid concrete is poured. In addition, it took a lot of time to brush off the formwork, and there was a big problem in workability. The present invention has been made in view of such a background, and an object thereof is to provide a new earthquake-resistant wall structure which is excellent in workability as well as an effect of preventing brittle fracture.

Increasing the spacing between partition walls does not hinder the filling of concrete as in the case of increasing the amount of wall reinforcement, so it is easy to reduce the wall plate thickness and increase the steel material ratio. 2> Corrugated steel plates on both surfaces share the shearing force with the filled concrete plate, and due to the joint resistance action with the vertical bulkhead integrated with this, the horizontal expansion and out-of-plane in-plane of the filled concrete plate <3> The vertical partition wall strongly suppresses vertical expansion and contraction in the plane of the filled concrete plate due to the joint resistance action of the corrugated steel plate attached to both vertical edges. 4> 1, 2 and 3 show that concrete with a thin plate thickness has a pressure field due to cable-stayed cracks when the interlaminar deformation angle of the floor where the earthquake-resistant wall is located is still small during an earthquake. To form , The increase of the restraining force as a reaction force from the reinforcement and formwork cannot be expected due to the yielding of the steel plate, and the shear force is increased until horizontal sliding failure occurs, that is, until the interlayer deformation angle of the floor becomes considerably large. The strain plate absorbs the strain energy while enduring the increase of the steel plate, and after the steel plate yields, the steel plate absorbs the larger strain energy. By acting as a high-performance laminated damper that is effective and shows almost no deterioration phenomenon, the shear strength per unit thickness of the wallboard is greater than that of the conventional type earthquake-resistant wall in which the concrete wallboard is reinforced with reinforcing bars. In addition, the toughness up to shear fracture and the absorption of strain energy both increased dramatically, and the interlaminar deformation angle of the tough wallless ramen portion was tracked until the end. As kill shear wall, it is possible to enhance the earthquake resistance of the walled rigid frame structure.

It can be installed at the site without much labor by being produced in the factory or grounded and hanging the troughs of the opposite corrugations easily. Water-tightness is good because it is made of steel plate, and since wall reinforcements that tend to be an obstacle during pouring are not placed in the formwork, it is suitable for pouring solid and good quality concrete. 3. Since the formwork doubles as a reinforcing material, the material can be used efficiently, and it also has excellent features such as labor saving because there is no need to remove the formwork.

FIG. 1 is a partial structural perspective view and a sectional view showing an embodiment of the present invention.
For example, as shown in FIG. 1, in the earthquake-resistant wall structure of the present invention, the side columns of the earthquake-resistant wall (1) are reinforced by the bellows steel pipe (2), and moreover, it becomes a factor of brittle fracture of the earthquake-resistant wall. For the purpose of preventing the concrete from peeling and collapsing out of the plane, the vertical arrangement was made so that the peaks and the troughs of which the busbars were oriented horizontally faced each other at a prescribed interval. Two corrugated steel plates (3) of the same shape are integrated with a vertical partition wall (5) of a strip-shaped steel plate provided in several places between them, and the concrete is filled in the wall body reinforcing material / wall body formwork. As a wall plate, a new earthquake-resistant wall structure with excellent brittle fracture prevention effect and labor-saving effect that does not require bar arrangement and demolding is used.
