[Embodiment 1-2] The present invention relates to a hinged seismic reinforcing frame, and in Embodiment 1-1, the seismic reinforcing beam is fastened to the opening with an anchor bolt; includes.

[Embodiment 1-3] The present invention relates to a hinged seismic reinforcing frame, and in Embodiment 1-1, a filling material is filled between the seismic reinforcing beam and the opening.

[Example 1-4] The present invention relates to a hinge-type earthquake-resistant reinforcing frame, and in Examples 1-3, the filler is epoxy.

[Example 1-5] The present invention relates to a hinged earthquake-resistant frame, and in Examples 1-3, the filler is mortar.

[Example 1-6] The present invention relates to a hinged seismic reinforcing frame, and in Examples 1-5, the filler is an ultra-fast mortar.

[Example 1-7] The present invention relates to a hinge-type earthquake-resistant reinforcing frame, and in Examples 1-5, the filler is non-shrinkage mortar.

The present invention (Examples 1-1 to 1-7) embodies the installation configuration of a hinged earthquake-resistant reinforcing frame.

After an earthquake, the degree of deformation and destruction of the structure (S, Structure) appears differently depending on the intensity of the earthquake, the type and age of the building, and the method of seismic reinforcement and damping method used.

In particular, the deformation of earthquake-resistant reinforcing members according to various reinforcement methods appears in various ways, such as elasticity, friction surface slip, plasticity, and shear failure.

If plastic and shear deformation beyond the elastic range occurs in the seismic reinforcing member, it cannot be restored to its original state even after an earthquake. The most commonly used method is to install structural materials such as wire ropes in the diagonal direction at the corner where the column and beam of the deformed building meet, correct the posture by tensioning, and reinforce the corner with reinforcing materials such as section steel.

However, due to various doors, windows, walls, etc. in buildings, it is not easy to install structural materials directly without partial or total disassembly.

Therefore, in order to install structural materials, it is necessary to install scaffolding inside and outside the building at the installation location or to remove walls and windows using aerial equipment, etc., so repair and reinforcement require a lot of time and money.

In the case of existing technologies, various types of reinforcing materials are installed during seismic reinforcement, and there is no problem with the seismic force within the stress range of the member, but the seismic force outside the stress range of the reinforcing member causes buckling of the reinforcing member, destruction of the welded joint, and deformation of the damper. etc., and repair is essential, and external physical force is required as a member of its own means to add resilience for correcting the posture of a distorted building. There is a disadvantage in that space openness is reduced by structural materials or reinforcing materials installed diagonally.

As another technology, when a damper using the viscosity of an elastic body and a fluid is used in the form of a brace, the role of the damper is to reduce the shock by mitigating the cycle of vibration, and this is also its own to add restoring force for correcting the posture of a distorted building. Since external physical force is required as a means member, it takes a lot of time and money to partially dismantle and additionally reinforce the building for this, and there are disadvantages in that space openness is reduced by the damper installed diagonally.

As described above, in most existing technologies, deformation outside the stress range of seismic reinforcing members generated in unexpectedly weak parts of the building structure or earthquakes exceeding the design standard caused plastic and shear deformation exceeding the elastic range in the building. There is a disadvantage that it is not possible to correct the posture of the building or perform rapid repair/reinforcement only with its own structure by the pre-installed seismic reinforcement method.

Therefore, in this proposal, in order to solve the problems of the existing technologies, a hinge part connected with a hinge fixing screw is placed at the corner where four earthquake-resistant reinforcing beams integrated with the pillars, beams, and slabs of the building meet. It is changed by angular displacement, and restoring force is provided on both sides of the hinge fixing screw in the longitudinal direction, so that restoring force can be easily added using pressurizing devices such as hydraulic cylinders with its own structure without additional reinforcement and installation of structural materials for adding external physical force. By providing a connecting plate at both ends of the hinge fixing screw, the angular displacement of the hinge part is changed into the slip and deformation of the friction surface of the planned member to prevent deformation of the main reinforcing member and absorb earthquake shock, related to seismic reinforcement and damping Focusing on the main functions in the hinge part, the inner and outer wall finishing materials of the hinge part are equipped with inspection holes to quickly check the state of the building and installed earthquake-resistant reinforcing members without dismantling the building after an earthquake, and to easily restore and repair and reinforce the deformation. as having been

The earthquake-resistant reinforcing beam can be integrated with the structure by forming a plurality of anchor holes in an opening where one side of the flange (or web) side is a ramen structure, that is, an installation surface of a pillar, beam, slab, etc. of a building, and fastening with an anchor bolt or the like. there is.

In addition, the seismic reinforcing beam may be filled with a filler for filling the space between the existing structure and the seismic reinforcing beam to improve integrity with the existing structure according to the nature of the structure, such as an RC structure or a steel frame structure. Specifically, the filler It may be an epoxy material.

In addition, when the structure is a reinforced concrete structure, that is, RC (Reinforcement Concrete) structure, it is possible to secure the continuity of coupling with the earthquake-resistant reinforcing beam by filling the mortar.

More preferably, the mortar can secure workability by applying ultra-fast-hardening mortar, and reduce cracking due to drying shrinkage of the concrete material as a filler by applying non-shrinkage mortar.

To this end, a fastening plate is welded to a side surface of the restoring pressing plate, and the connecting plate is bound to the fastening plate so that the adjacent earthquake-resistant reinforcing beams can be mutually rigid.

Therefore, the connection plate provided in the hinge plate area converts the large deformation amount of horizontal displacement due to the lateral force during an earthquake into a small amount of deformation of the angular displacement, thereby preventing the destruction of the main reinforcing member and simplifying the maintenance of the earthquake-resistant reinforcing frame. It is possible to promote economic improvement by replacing only the

In addition, the connecting plate serves to prevent brittle fracture of the structure and induce ductile behavior by performing a damping function as a hysteretic metallic damper.

In order to connect the connecting plate to the fastening plate, a connecting plate attachment hole may be formed in the fastening plate and the connecting plate may be fixed with a fixing bolt.

To this end, a hole corresponding to the fastening hole may be formed in the connecting plate. In consideration of the hole position change due to rotation of the hinge plate, the hole applied to the connecting plate may be formed as a slit-shaped fixed slit hole.

The fixed slit hole may be specifically formed in a radial shape drawing a concentric circle based on the hinge center of the hinge plate.

One or more deformable slit holes may be formed in the connection plate to induce deformation.

When a load is applied to the seismic reinforcing frame due to an external force such as an earthquake, the load is concentrated on the connecting plate installed at the hinge plate connection part. That is the role of the deformable slit hole.

The deformable slit hole may be specifically formed by configuring a plurality of slit holes in the connecting plate.

Like the deformable slit hole, the stress concentration region of the connecting plate may be formed in various ways. Specifically, the shape of the position where the deformation is to be induced, such as forming the end of the connecting plate with a recessed shape or forming a curved central portion of the connecting plate. can be limited.

The connection plate may be formed in plurality at a symmetrical position about the hinge of the hinge plate.

The connecting plate may increase the tensile strength of the connecting plate while maintaining relatively good workability compared to a general steel plate by applying a high-strength steel plate, and may promote ductility behavior by applying a steel plate having an increased yield point.
