Description

FIELD OF THE INVENTION [0001] The present invention relates to a wall-to-wall inversion prevention system using a torsion material,

The present invention relates to a system for preventing out-of-plane conduction of a rough filled wall using a tensile material which can secure the stability and durability of a structure by preventing the out-of-plane conduction of the roughly filled wall in a simple detail without damaging the structure.

In the Raynimyo frame, a non-proof masonry wall is constructed between the upper and lower floors, which is relatively easy to construct.

However, in general, the joints between the structure and the masonry filler walls are vulnerable to lateral loads due to difficulty in precise construction. Therefore, when the out-of-plane direction load acts on the roughly filled wall standing vertically between the upper and lower floor layers due to earthquake load or the like, as shown in FIG. 1, the roughly filled wall 2 undergoes sudden brittle fracture It can cause collapse.

In order to prevent the above-mentioned out-of-plane conduction, conventionally, an angle is provided between the upper beam 1 and the rough fill wall 2 as shown in FIG. 2 (a), or a dowel bar is installed as shown in FIG. 2 Thereby permitting the relative movement between the upper structure and the masonry filling wall 2, and at the same time being able to resist the load in the out-of-plane direction.

However, in the conventional method as described above, since an angle or a dowel bar should be fixed to an existing structure by anchoring or perforating, damage to the existing structure is inevitable.

In addition, there is a method of removing existing masonry walls and installing steel bracing to improve the seismic performance of the masonry walls. However, this method has a problem in that the process is complicated, the construction period is long, and it is uneconomical.

In addition, there is a technique of a seismic strengthening method of a wall wall that can expect the improvement of the strength by the reinforcing effect and the restraining effect of the wire rope by restraining the existing masonry wall using the wire rope (Patent No. 10-1027393).

However, the above method also has a disadvantage in that construction is complicated. In addition, since the thickness of the roughly filled wall is thinner than the width of the beam, since the steel wire is provided on the side wall, the distance between the steel wire and the wall of the wall is too long.

In addition, when the tension is applied to the steel wire, there arises a problem that the beam and the slab are sagged, and a prestress can not be applied to the steel wall, so that the effect of increasing the rigidity of the steel wall can not be expected.

In order to solve the above problems, it is not necessary to dismantle an existing structure or to form an anchoring or perforation hole in a beam member or an artificial filling wall, Walled out-of-plane conduction preventing system using a tautable material.

The present invention is to provide a system for preventing out-of-plane transition of an artificial filling wall by using a tensile material capable of effectively preventing the out-of-plane conduction of the artificial filling wall by placing a tension member at the bottom of the beam.

SUMMARY OF THE INVENTION The present invention is directed to a system for preventing out-of-plane transition of a masonry-filled wall using a prestressing material that can increase the rigidity of the masonry-filled wall by introducing a prestress into the masonry-filled wall.

According to a preferred embodiment of the present invention, a plate member inserted between the beam and the artificial filling wall to prevent out-of-plane conduction of the artificial filling wall provided in the beam lower portion. A pair of angle members coupled to both sides of the upper surface of the plate member, the one leg being coupled to one side of the upper surface of the plate member and the other leg supporting the lower side of the plate; And a tension member provided at both sides of the rough filler wall, one end of which is fixed to the bottom slab and the other end of which is connected to a lower portion of the plate member; The present invention provides a system for preventing out-of-plane transition of a rough filled wall using a tensile material.

According to another preferred embodiment of the present invention, the tension member is provided with a turnbuckle for introducing the post tension to the tension member, respectively.

According to another preferred embodiment of the present invention, the plate member is formed with through holes at positions where the tension members are connected, and the tension members on both sides of the rough filler wall are connected to each other through the through holes. Provides a wall-to-wall outfall avoidance system.

According to another preferred embodiment of the present invention, there is provided a system for preventing out-of-plane transition of a rough filling wall using a tensile material, characterized in that a turnbuckle is provided on the tension material on one side of the rough fill wall.

According to another preferred embodiment of the present invention, a guide pipe for supporting a lower portion of a tensile material is provided inside the through-hole on the upper surface of the plate member.

According to another preferred embodiment of the present invention, an energy dissipating pad is provided between the other leg and the side surface of the angle member.

The present invention has the following effects.

First, by joining the plate member inserted between the beam and the masonry wall to the beam with the angle member, and by connecting the tension member to the floor slab and the plate member, It is possible to prevent conduction.

Particularly, since the tension material is provided on the side of the beam-side projecting wall rather than the beam-side wall, the distance between the tensioning material and the projective wall is close to each other.

Second, by introducing a prestress into the rough fill wall, it is possible to greatly increase the in-plane rigidity as well as the out-of-plane rigidity of the rough fill wall.

Third, since the construction details are simple, it is possible to improve the workability and shorten the construction time and reduce the construction cost.

Fourth, even if tension is applied to the tensional material, there is no problem of slipping or slipping.

Fifth, when the energy dissipating pad is provided between the other leg and the beam side of the angle member, the energy dissipating pad can absorb and dissipate the in-plane vibration of the rough filling wall.
