The present invention relates to a seismic brick and a seismic wall using the same, and more specifically, having a coupling groove on the upper and lower surfaces of the brick, reinforcing the brick and the filler by a fiber reinforcement, and installing a seismic pad at each end of the stacked bricks And a wall that is reinforced against shear.

In the meantime, our country is considered as a safe area for earthquakes, so the impact of earthquakes on the design of structures has been designed and constructed without much consideration. However, the recent earthquake has occurred in Korea after the Japanese archipelago, and the earthquake resistance of the structure is rising due to the catastrophe caused by the earthquake in Southeast Asia. In addition, in our design standards, earthquake resistance is required for certain structures.

The wall according to the prior art has a smooth surface and comprises a brick composed of a rectangular parallelepiped. Stacking these bricks in zigzag-shaped stages, they are filled with cement mortar, etc., in order to join each brick.

Both ends of the wall thus joined are joined by an adhesive force of cement mortar to the column.

The conventional wall structure configured as described above may be formed by stacking bricks in one row, but most of the walls are stacked in two rows to form a wall. In the case of residential structures, a predetermined space is provided between the rows, and the insulation is formed therein.

In the conventional wall having such a configuration, each member is joined by cement mortar, and the joining surface of each member and cement mortar is a weak cross section for tensile force.

However, the prior art as described above has the following problems.

That is, since the bricks are supported only by the adhesive force of the concrete, the joint surface of the brick and the concrete had a weak point against the shear stress and the bending tensile stress.

In addition, when the walls are arranged in two rows, when the bending moment acts on the wall, the shear stress acts between the front row and the back row, and the concrete is a material vulnerable to the shear, so that the front row and the back row are easily separated. Therefore, when an earthquake occurs, horizontal and vertical vibrations are generated by seismic waves, and the wall according to the prior art is easily separated from each other by the horizontal vibration and the columns of the walls are easily separated by the vertical vibration. It was easy to be separated from the concrete, and there was a problem of being easily destroyed.

In the prior art, since the wall is coupled only by the pillar and the cement mortar, the side surface of the wall is easily separated from the pillar.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a structure of a seismic brick that can generate a structural engagement between the bricks and can be easily reinforced against tension.

Another object of the present invention is to provide a structure of a seismic wall that can effectively resist the shear stress caused by the step difference caused in the wall.

Another object of the present invention is to provide a structure of a seismic wall such that a structural engagement occurs between the wall and the pillar supporting the wall.

According to a feature of the present invention for achieving the object as described above, the brick of the present invention is formed with a groove on the upper and lower surfaces so that the filler penetrates the groove to form a structural engagement.

The groove is formed in a wide shape inside, it is formed long in the longitudinal or transverse direction.

On the other hand, the brick is compounded and cured, including the fiber reinforcement at the time of manufacture, the ends of the fiber reinforcement may be to come out of the seismic brick.

In addition, when looking at the wall installed using the above-described brick, the seismic brick is stacked in one row or two rows in a multi-stage, and the groove is formed on the upper and lower surfaces, and the stacked seismic brick is formed in the seismic brick It is formed by including a filler that penetrates into the groove and harden after filling the groove.

The seismic bricks are compounded and cured, including fiber reinforcement, during manufacture, and the ends of the fiber reinforcement come out of the seismic brick.

And, between each end of the piled up seismic brick, has a predetermined thickness, has a width corresponding to the width of the seismic brick, is formed in a length corresponding to the length of the wall, the space is formed in the form of a ladder The formed seismic pad is installed. On the other hand, when the seismic bricks are stacked in two stages, the width of the seismic pad is formed to correspond to the width of the wall.

The seismic pad is formed of a soft material, and one long seismic pad is formed to fold up between each end.

The seismic wall further includes a support column having a wall groove corresponding to the width of the seismic wall so that the side end of the wall can be fitted to the side end portion.

Such a seismic wall is a step (A1) to erect a column at the end where the wall is to be erected; Passing the remaining portion of the seismic pads through the pillar (A3), the step of installing the seismic brick on the seismic pads installed (A4), the step of placing the filler on the seismic bricks installed (A5), and (A3) By repeating the steps (A5) to the step (A6) to form a wall to the desired height.

At this time, the seismic pads are installed in one or two rows depending on the purpose of the wall.

And the pillar may not be installed depending on the purpose of the wall. That is, the seismic wall according to the present invention may be constructed by the steps (A2) to (A3).

According to the present invention having the configuration as described above, the structural engagement is formed between each member constituting the wall structure, the tensile strength is increased, the seismic pad resists the tensile force and the resistance to shear stress is increased, The wall is stably supported by the structural engagement of the wall with the column.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of the seismic wall according to the present invention as described above will be described in detail.

Figure 1a is a perspective view showing a preferred embodiment of the seismic brick according to the present invention, Figure 1b is a cross-sectional view showing the various cross-sectional shape of the seismic brick according to the present invention, Figure 1c is another embodiment of the seismic brick according to the present invention Example is a perspective view, Figure 2 is a perspective view showing a seismic pad constituting a preferred embodiment of the present invention, Figure 3 is a side cross-sectional view showing a seismic wall is installed in two stages of the seismic brick of the present invention, Figure 4 is a perspective view showing a state in which the wall is coupled to the support pillar constituting the configuration of the present invention, Figure 5 is a perspective view showing a state in which two columns of the wall is coupled to the support pillar constituting the configuration of the present invention.

As shown in these figures, the brick according to the present invention (hereinafter referred to as "earthquake-resistant brick") is formed with a groove (hereinafter referred to as a 'coupled groove') on the upper and lower surfaces. The coupling groove 12 is formed as shown in the cross-sectional shape in Figure 1, the inner side is formed wide so that when the filler to be described later is filled and cured, it is formed so that separation by tension is not easy.

The coupling groove 12 may be formed as a plurality of independent grooves, but preferably is formed long in the longitudinal direction as shown in Figure 1a, or as shown in Figure 1c, a plurality is formed along the transverse direction It is also possible to form a lattice groove. The direction of the coupling groove 12 is determined by the load direction that the wall receives, and is preferably formed in a direction perpendicular to the neutral axis for bending of the wall section.

Meanwhile, the seismic brick 10 may be cured by adding a fiber reinforcement 14 during manufacture, and the fiber reinforcement 14 reinforces the seismic brick 10 itself and is mixed with the filler 30 to be described later. Curing serves to increase the bonding force of the filler 30 and the seismic brick 10. Thus, the end of the fiber reinforcement 14 is exposed to the outside of the seismic brick 10. The fiber reinforcement 14 may be made of a variety of materials, such as fiber, glass fiber is preferably used. Furthermore, since the seismic brick 10 can be made of concrete, the fiber reinforcement 14 is preferably made of an alkali resistant material so as not to be damaged by concrete having alkalinity.

The seismic brick 10 may be formed in various forms, but in consideration of workability, it is preferably formed in the shape of a rectangular parallelepiped.

Hereinafter, the structure of the earthquake-proof wall made by the above-mentioned earthquake-resistant brick is examined.

The seismic brick 10 is stacked in multiple stages to form the center of the seismic wall according to the present invention.

Between each end of the piled up seismic brick 10, a pad having a predetermined thickness and a through hole 22 formed therein (hereinafter referred to as a “seismic pad”) is installed, and the seismic pad 20 is formed of a wall. It is formed to have a width corresponding to the width. For example, when the seismic bricks 10 are stacked in one row, the seismic pads 20 are formed to have the same width as that of the seismic bricks 10, and when the seismic bricks 10 are stacked in two rows. The seismic bricks 10 are formed to have the same width as the two widths. In addition, when the seismic bricks 10 are stacked in two rows and a predetermined space is formed therebetween so that a heat insulating material is provided, the width of the seismic pad 20 is equal to the width of the two seismic bricks 10. Plus size. Of course, even if a predetermined space is formed between the two rows of seismic bricks 10 and the insulation material is provided, it is also possible to install the seismic pads 20 for each row for convenience of workability. On the other hand, the through hole 22 formed in the seismic pad 20 is continuously formed in the shape of a rectangle, the size of the seismic pad 20 is preferably formed so that only the edge portion remains. The seismic pad 20 is buried between the filler 30 to be described later is fixed as the filler 30 is cured.

The seismic pad 20 may be formed of various materials having ductility, but preferably, the fabric is formed by supplying fibers and filament yarns in the form of fabric or knit fabric in the direction of warp and weft yarns, respectively, and fabricating the fabric. It is made by coating the fabric by melting resins such as PVC, bitumen, coal tar, etc. with application solvents to give rigidity to the joint and to strengthen the bonding at the bonding point of light and weft. In addition, since concrete may be used as the filler 30 to bond the seismic pad 20, the seismic pad 20 is preferably made of an alkali resistant material so as not to be damaged by concrete having alkaline properties. .

The seismic pad 20 described above serves to resist the shear stress that the wall receives in the horizontal direction with the ground, and to use one seismic pad 20 in a manner of folding up, so that each end is pushed in the horizontal direction. It serves to prevent. In particular, when the wall is composed of a plurality of rows of the seismic brick 10, the seismic pad 20 serves to prevent each row of the seismic brick 10 is separated. That is, it acts as a reinforcing material to reinforce the shear stress generated in the mating surface of each row of seismic stones due to uneven settlement and bending moment.

Between the seismic brick 10 and the adjacent earthquake-resistant brick 10 is filled with a filler 30 to combine them. The filler 30 may be concrete, cement mortar, ascon, etc. The type of the filler 30 is determined according to the purpose of the seismic wall.

Since the filler 30 has fluidity before curing, the filler 30 penetrates the coupling groove 12 to fill the coupling groove 12, and is buried together with the distal end of the fiber reinforcing material 14. Wrap Thereafter, when the filler 30 is cured, structural coupling with the seismic brick 10 occurs by the coupling, and the fiber 30 is cured with the fiber reinforcement 14 embedded therein.

On the other hand, as shown in Figure 4, the side end of the wall is provided with a support pillar 40 formed with a longitudinal groove 42 (hereinafter referred to as a 'wall groove') in which the wall can be fitted. As shown in FIG. 4, the position of the wall groove 42 of the support pillar 40 is determined according to the wall to be installed. For example, when the wall is installed on both sides, a pillar having an I-type cross section is installed. When the wall is installed at right angles, a column in which the wall grooves 42 are formed at right angles is used, and in the case of the end of the wall, a pillar having a "c" shape is installed.

The wall groove 42 formed in the pillar generates a structural engagement with the side end of the wall, so that the entire wall firmly reinforced by the coupling groove 12, the fiber reinforcement 14, and the seismic pad 20 described above. It serves to prevent any passing.

The seismic wall according to the present invention having such a configuration is constructed in the following order.

6A to 6G are construction flowcharts showing the construction sequence of the present invention.

Hereinafter, the construction sequence of the seismic wall is divided into steps A1 to A6 to examine each step in detail.

First, the support pillar 40 for supporting the wall is erected at the side end position of the wall to be installed (A1). The support pillar 40 is installed in a form in which the wall groove 42 is formed along the longitudinal direction of the support pillar 40 so that the side end of the wall can be fitted. Preferably, a reinforced concrete column is used as the support pillar 40. When the reinforced concrete pillar is poured, the ground is dug to a predetermined depth in the place where the support pillar 40 is to be placed and the longitudinal reinforcement and the band reinforcement are reinforced. After assembling, pour concrete and mold to cure.

Next, as shown in Figure 6a, evenly ground the ground on which the wall is erected and pours the filler 30 in the position where the wall will be placed from the wall groove 42 of the one side to the other wall groove 42 (A2) . Concrete is preferably used as the filler 30.

6B, the seismic pads 20 are installed on the filler 30 placed on the foundation ground (A3). Since the width of the seismic pad 20 is made according to the width of the wall to be installed, it can be installed straight from the inside of the wall groove 42 on one side to the inside of the wall groove on the other side. At this time, the end of the seismic pad 20 is raised up along the wall groove 42 without cutting to fit the length, and is carried over the support pillar 40. This is because the seismic pad 20 is formed of a soft material as described above, and thus can be folded freely.

Thereafter, as shown in FIG. 6C, the seismic brick 10 is placed on the seismic pad 20 provided at a predetermined interval (A4). Until this time, since the filler 30 is not cured, the seismic pads 20 are buried in the filler 30 by the weight of the seismic brick 10 and the coupling grooves formed on the lower surface of the seismic brick 10 ( 12) The filler 30 also penetrates inside. Preferably, for this purpose, it is also possible to press the seismic brick 10 with a predetermined force after installing the seismic brick 10.

Next, as shown in FIG. 6D, the filler 30 is poured between the seismic brick 10 and the adjacent seismic brick 10 and along the upper surface of the seismic brick 10 (A5). At this time, the filler 30 having fluidity soaks into the coupling groove 12 formed on the upper surface of the seismic brick 10.

6E and 6F, the seismic wall is constructed to the desired height by repeating the steps (A3) to (A4) (A6). The appearance of the completed seismic wall is as shown in FIG. 6G.

On the other hand, the seismic brick 10 can be installed in two rows differently, in this case, in the step (A1), the wall groove 42 of the support pillar is formed so that two rows of the seismic brick 10 enter. In addition, in step (A2), the seismic pad 20 is also formed to a width corresponding to the width of the two rows of the seismic brick 10.

Alternatively, in the seismic wall according to the present invention, a pillar having a general rectangular cross section in which the wall groove 42 is not formed may be used. In this case, the wall and the pillar may be supported by the attachment force of the filler 30, or may be further constructed by installing a separate fastener such as an anchor bolt to be supported by a separate fastener.

Hereinafter, the action of the seismic wall according to the present invention will be described in detail according to the type of vibration and load applied to the seismic wall.

When the seismic wall as described above occurs inequality settlement or a vibration is applied to the left and right of the wall, such as seismic waves, longitudinal shear stress is generated in the wall. At this time, since the seismic pad 20 is installed in the transverse direction, it resists the above shear stress. In this case, it serves as a shear reinforcing bar. In addition, even if the seismic brick 10 is installed in two rows serves as a shear reinforcing bar to prevent each row from being separated.

On the other hand, when the seismic wall receives a horizontal load and a bending stress is generated inside the wall, the dangerous cross section becomes a joining surface of the filler 30 and the brick, which is an attachment portion of the material. In the seismic wall according to the present invention, after the filler 30 is cured, structural engagement occurs between the filler 30 and the seismic brick 10, and the fiber reinforcement 14 is the filler 30 and the seismic brick. Because of the connection between (10), the tensile strength of the joint surface of the two materials is increased.

And even in the case of a rigidly manufactured wall, there is a risk that the whole wall is conductive when the column and the coupling force is weak, the seismic wall according to the present invention is supported by the structural engagement is inserted into the wall groove 42 at both ends. .

The rights of the present invention are not limited to the embodiments described above, but are defined by the claims, and those skilled in the art can make various modifications and adaptations within the scope of the claims. It is self-evident.

In the seismic wall according to the present invention as described in detail above, the following effects can be expected.

That is, there is a structural engagement between the seismic brick and the filler, and the fiber reinforcement is resistant to the tensile stress therebetween has a high bonding strength of the seismic brick and the filler. In particular, when the seismic wall is subjected to bending stress, there is an advantage that it can effectively resist the bending tensile stress generated inside.

And in the present invention, since the seismic pads are connected to each end, it serves as a shear reinforcement. In other words, if the seismic wall is inevitably settled, but the step is caused by the seismic wave, the shear stress is generated along the longitudinal section of the seismic wall. In this case, the seismic pad is tensioned, and the seismic pad resists shear stress and thus has an advantage of showing shear reinforcing effect.

In addition, the support pillar and the wall according to the present invention are coupled by structural engagement by wall grooves formed in the support pillar. Therefore, the bonding strength is superior to the conventional wall that is coupled only by the filler, there is an advantage that can prevent the entire wall is conducted.
