Description

Technical Field [0001] The present invention relates to a reinforced structural system for securing seismic performance by reinforcing the existing masonry wall,

BACKGROUND OF THE INVENTION 1.

More particularly, the present invention relates to a technique for supporting and reinforcing a masonry wall to act as an earthquake-

In accordance with Article 14 of the Earthquake Disaster Preparedness Act, seismic retrofitting of existing buildings in Korea is being promoted. The current method is to stabilize the facilities through reinforcement of the main structural parts and prevent the collapse of the earthquake.

However, investigating the causes of casualties in the event of an earthquake, it can be seen that the secondary damage (60%) due to the destruction of non-structural members is larger than the direct damage (40%) due to the collapse of the building. Therefore, if the seismic performance of the main structural members is improved and the non-structural members are reinforced simultaneously, substantial seismic strengthening is possible.

The partition walls of existing buildings made of reinforced concrete structure are piled up with bricks, which are embedded in a four-way concrete structure. Due to the nature of coarse masonry walls, shear forces due to lateral forces are very weak. Particularly, the part where the brick is abutted to the upper concrete beam is the part where the brick is laid without the adhesive mortar or the empty space is the most, and the cause of the damage may be caused by collapse when the earthquake occurs.

Therefore, it is urgent to develop a reinforcement method. However, seismic retrofitting is currently being carried out only on reinforcement of main structural parts to prevent building collapse.

Conventionally, the seismic strengthening method for the non-major structural part has a method of increasing the cross section of the existing masonry wall, but it is difficult to complete the construction during the short vacation period due to the difficulty in the progressive strength and complex construction, There is a problem that it is difficult.

In FIGS. 1 to 4 and 7, shaded portions indicate that a reinforcing film 300 described later is formed. 1 to 4, the unshaded portion is for explaining a portion located inside the reinforcement film 300 for the purpose of clear understanding of the invention, and means that the reinforcement film 300 is not formed no.

FIG. 1 is a front view of a masonry wall of an anti-seismic steel structure according to an embodiment of the present invention, and FIG. 2 is a front view of an anti-masonry steel structure in which an opening of the masonry wall is connected to a frame according to another embodiment of the present invention.

The anti-seizure steel structure 10 according to an embodiment of the present invention may include the masonry wall 100, the panel member 200, and the reinforcement film 300.

Before describing the embodiments of the present invention, the frames 1 and 2 used in this specification will be described. The frames 1 and 2 may be constructions constituting a space formed by the columns 1 and the beams 2. In the drawings of this specification, a rectangular shape is shown, but the present invention is not limited thereto.

The columns 1 and beams 2 may be constructions of concrete. Specifically, the columns 1 and beams 2 described below can be ceilings and columns in a concrete structure, and are not limited to the shapes shown in the drawings. Therefore, the frames 1 and 2 do not necessarily have a rectangular shape, but may be formed in various shapes.

The masonry wall 100 may be formed of a stone or glass fiber block.

When it is made of stone, it can take the form of various types of bricks, such as general brick, cement brick, hole brick and cavity brick. The listed types are only one example, so that various types of bricks can be used without being limited to the listed types.

Mortar can be used to bond the bricks when the masonry wall 100 is formed of a masonry. Mortar is made by mixing cement and sand with water. It can be classified into various kinds of mortar depending on the type of fixing material, but it is not limited to a specific kind of mortar.

The glass fiber block may be a block of glass fibers extruded by recycling the waste. Unlike ordinary bricks, glass fiber blocks can be easily assembled and can be easily constructed. In the case where the roughwall 100 is formed of a glass fiber block, only a portion in contact with a frame described later can be bonded to the frame by mortar.

The panel member 200 may be a member padded to the frames 1, 2. The panel member 200 may include glass fiber reinforced plastic (GFRP) or may include an iron plate. GFRP panels are characterized by similar thermal expansion coefficients to concrete. Further, when a GFRP panel is used, mutual integrity can be ensured between the reinforced structure and the adhesive. In addition, the tensile strength and the bending strength of the structure to be reinforced can be increased, and the stability of the structure to be reinforced can be secured.

The panel member 200 may be attached to the outer and inner surfaces of the frames 1 and 2 and may be formed to cover the rim of the masonry wall 100. [ The panel member 200 may be fixed through a wedge anchor or the like to attach the panel member 200 to the frames 1 and 2, and then epoxy may be injected and attached.

The panel member 200 may be formed in the form of a plate having a predetermined thickness and may be formed to be wider than the width of the column 1 and the beam 2 to cover the rim of the masonry wall 100. The panel member 200 may be attached to the edge of the masonry wall 100 through a separate sealing material (not shown). At this time, the sealing material can be formed by mixing the base material and the curing agent in a ratio of 1: 1. However, the ratio of the curing agent and the curing agent to be mixed may be varied depending on the concrete embodiment.

An opening 110 may be formed in the coarse wall 100 so that a window can be disposed. At this time, the opening 110 may be formed in a rectangular shape in the masonry wall 100. However, the present invention is not limited thereto, and the shape of the window may be changed according to the embodiment, and thus the shape of the opening may be changed. Hereinafter, for the sake of clear understanding of the invention, the opening 110 will be described with reference to a rectangular shape.

The opening 110 formed in the coarse wall 100 may be formed in a "? &Quot; shape or a "? &Quot; shape. That is, the rim of the opening 110 may be entirely formed of the masonry wall 100, or one side of the rim may be formed of the beam 2.

The panel member 200 attached to the rim of the opening 110 will be described later.

The reinforcing film 300 may be formed of a polymer compound. Specifically a reaction product with a polyether and an isocyanate. The reinforcing membrane 300 includes a panel member 200 positioned on the outer and inner sides of the frames 1 and 2 through spraying and a panel member 200 positioned around the opening 110 when the opening 110 is formed. And the entire masonry wall 100, as shown in Fig. When applied through a spray, it can be cured within a few seconds to several tens of seconds to form an elastic coating film. The elastic coating film formed at this time may be the reinforcing film 300. Preferably, the polymeric compound forming the reinforcing membrane 300 may be a polyurea. The polyurea can have excellent physical properties such as tensile strength, tear strength, elongation, abrasion resistance and adhesion.

The reinforcing membrane 300 may serve to help the panel members 200, the masonry wall 100, and the frames 1 and 2 to move integrally. The panel member 200, the masonry wall 100 and the frames 1 and 2 can be integrally moved in the event of an earthquake or the like, so that the applied forces can be dispersed to each other. This makes it possible to effectively share the applied stress.

When the reinforcing film 300 is formed, the integrated structure of the masonry wall 100 and the frames 1 and 2 is enhanced, so that the maximum strength can be enhanced. In addition, an effect of preventing stress from being conducted in the out-of-plane direction of the coarse wall body 100 can be produced.

Unlike the panel member 200 and the reinforcement members 410 and 420 described later, the reinforcement film 300 may be formed on both the outer and inner surfaces. The panel member 200 and the reinforcing members 410 and 420 may be formed only on one of the outer and inner sides according to the cost reduction or specific embodiments. However, the reinforcing film 300 may be formed on both the outer and inner surfaces The impact resistance can be improved. If the reinforcing film 300 is applied only on the end face, even if a force is applied to the place where the reinforcing film 300 is formed, the destruction can occur at a place where the reinforcing film 300 is not formed.

FIG. 3 is a front view of a masonry wall of an anti-seismic steel structure including a reinforcing member according to another embodiment of the present invention, and FIG. 4 is a cross- It is the front view of the masonry wall.

The reinforcement steel structure 10 'according to another embodiment of the present invention may further include reinforcing members 410 and 420.

The reinforcing members 410 and 420 may be members arranged at predetermined intervals on the outer side surface and the inner side surface of the masonry wall 100. [ The shape of the reinforcing members 410 and 420 may be similar to that of a reinforcing bar, but may be formed of glass fiber reinforced plastic (GFRP). When the reinforcing members 410 and 420 are formed of GFRP, they are light in weight and excellent in properties such as durability, impact resistance and abrasion resistance. In addition, there is an advantage that it is not rusted, the thermal conductivity is low, and the processing is easy.

The reinforcement members 410 and 420 may include a vertical reinforcement member 410 arranged in a vertical direction and a horizontal reinforcement member 420 arranged horizontally. The ends of the vertical reinforcement member 410 and the horizontal reinforcement member 420 may be attached to the panel member 200 as a sealing material. This makes it possible for the reinforcing members 410 and 420, the panel member 200, the masonry wall 100 and the frame to behave integrally in the event of an earthquake or the like.

As the vertical reinforcement member 410 and the horizontal reinforcement member 420 are arranged, a pattern of a lattice pattern may be formed on the masonry wall 100. At this time, the fixing member 450 connecting the vertical reinforcing member 410 and the horizontal reinforcing member 420 may be connected to enhance mutual integrity. The fixing member 450 will be described later.

5 is a view showing a fixing member connecting the vertical reinforcing member and the horizontal reinforcing member.

The fixing member 450 may include a fixing cap 451 and a fixing bolt 452.

The fixing member 450 may be formed at the intersection of the vertical reinforcement member 410 and the horizontal reinforcement member 420.

The fixed cap 451 may be formed with a groove (not shown) into which the vertical reinforcing member 410 and the horizontal reinforcing member 420 can be inserted. The vertical reinforcement member 410 and the horizontal reinforcement member 420 can be prevented from being shaken when a force is applied by being inserted into the groove.

The fixing cap 451 may have a predetermined width, and a fixing bolt 452 passing through the fixing cap 451 may be fastened and coupled. The fixing bolt 452 can penetrate the masonry wall 100. The fixing member 450 on the outer and inner surfaces of the masonry wall 100 can be connected through the fixing bolts 452. [

However, the fixing bolt 452 does not necessarily penetrate through the masonry wall 100. According to a specific embodiment, the fixing bolt 452 may be formed to be inserted into the masonry wall 100. As the fixing bolts 452 are tightened, the fixing force acting on the vertical reinforcing member 410 and the horizontal reinforcing member 420 can be strengthened and the reinforcing members 410 and 420 can be made close to the mural wall 100 . As a result, the integrity of the reinforcing members 410, 420 and the masonry wall 100 can be improved.

6 is a cross-sectional view taken along line I-I 'of FIG.

A panel member 200 attached to the outer and inner surfaces of the frames 1 and 2 is attached to the frame members 1 and 2 after the panel members 200 are attached to the frame members 1 and 2, 210, respectively. The mutual integral can be improved by fixing the panel member 200 attached to the outer side surface and the inner side surface of the frame 1, 2 through the through-wall member 100 through the penetrating member 210.

Also. The panel member 200 may be formed to surround the masonry wall 100 in a " C " shape along the periphery of the opening 110. [ The panel member 200 formed on the outer side surface and the inner side surface of the masonry wall body 100 can be connected through the penetrating member 210. [ When the opening 110 is formed, stress concentration may occur on the side of the opening 110. Thus, by attaching the panel member 200, the damage due to stress concentration can be reduced. For example, when an earthquake occurs or a force is applied to the side of the masonry wall 100, it is possible to prevent cracks that may occur from around the window.

7 is a view showing an anti-seismic steel structure having a partially reinforced membrane according to another embodiment of the present invention.

The reinforcement film 300 can be applied to the outer side surface and the entire inner side surface of the masonry wall 100 and the frames 1, 2. However, it can be partially formed in a specific use. Cracks may be generated first in the portion where the column 1 and the beam 2 meet and in the portion where the column 1 and the bottom (not shown) are connected when a force is applied to the frame 1 or 2 side.

In order to effectively form the reinforcement film 300 by a practical constraint such as a financial reason, a construction problem, or a construction time limit, it may be preferable to form the reinforcement film 300 first on the corner portion as described above.

At this time, the reinforcing film 300 may be formed to include the rim portion of the masonry wall 100, rather than being formed on the pillar 1 and the beam 2. However, the rim portion where the reinforcing membrane 300 is formed may be a corner portion of the portion connected to the frames 1 and 2, not the entire rim portion of the masonry wall 100.

In the case of an emergency such as an earthquake, if the reinforcing film is formed only in the corner portion since the corner portion is first cracked or broken, a great effect can be obtained while minimizing the reinforcing film 300. It may be efficient to partially form the reinforcing film 300 in the presence of the practical limitations described above.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, . Therefore, the scope of the present invention should not be limited to the above-described embodiments, but should be determined by equivalents to the appended claims, as well as the appended claims.
