Description

Seismic anchor for fixing exterior bricks and construction method of earthquake-resistant anchor for fixing exterior bricks using the same}

The present invention relates to an anchor that binds the exterior bricks and the interior wall of a building to reinforce the exterior bricks and its construction method. In particular, a seismic anchor with enhanced seismic performance by forming cartridges that are simultaneously fixed to the exterior bricks and the interior wall, respectively, and a seismic anchor using the same. This relates to the construction method of earthquake-resistant anchors.

Many houses, schools, public facilities, religious facilities, military bases, factories, and other buildings have exterior walls made of exterior brick. These exterior bricks deteriorate over time as they are exposed to the environment for a long time, and the fixing hardware that connects the interior wall and the exterior bricks also oxidizes and rusts over a long period of time, gradually losing its holding power, even when exposed to weak external vibrations. In reality, many falling accidents occur due to brick collapse due to exterior bricks breaking away from the interior, and personal accidents due to brick collapse are also occurring.

The fastening hardware that connects the interior wall and exterior bricks is usually made of anchor bolts. However, the force with which the anchor bolt fastens the inner wall and the exterior brick is achieved by the expansion of the anchor inside the inner wall and the exterior brick. In this way, the state in which the rigid member is fixed within the stone can be damaged over a long period of time when exposed to various vibrations, rain, wind, or temperature differences. As they inevitably become loose, more fundamental measures are required to prevent the collapse of exterior bricks.

Moreover, while recent earthquakes on the Korean Peninsula are gradually becoming stronger and faster in frequency, the current exterior brick construction method does not have a basic earthquake-resistant design to prepare for earthquakes. Therefore, relying only on conventional stone anchors can lead to the collapse of the exterior bricks. It is impossible to make a fundamental comparison.

Registered Patent Publication No. 10-1162109 (Publication date: 2012. 07. 03)

Accordingly, the present invention binds the exterior bricks and the interior wall through a combination of resin and anchor, thereby fundamentally solving the phenomenon of anchors in the form of expansion of rigid members within conventional stone becoming loose over time, while providing greater fastening force. In addition, the installation of the anchor and the filling process of the resin are extremely simple, and the phenomenon of resin overflowing and dripping can be prevented, and an internal framework that can reinforce the filled resin can be formed together, thereby preventing earthquake vibration. The aim is to provide a seismic anchor for fixing exterior bricks that can be maintained firmly even in the event of a storm, and a method of constructing the same.

A seismic anchor for fixing exterior bricks according to the present invention for achieving this purpose includes an anchor rod inserted into a perforated hole that passes straight through the inner wall and the exterior brick, and the perforated hole installed at the tip of the anchor rod and formed in the inner wall. It includes an inner wall side anchor inserted into the inner wall side anchor, and an exterior brick side anchor installed between the rear end and the front end of the anchor rod and inserted into the perforated hole formed in the exterior brick, wherein the inner wall side anchor is rotated by the anchor rod. It is fixed to the inner wall, and the exterior brick-side anchor is configured to be fixed by curing the resin filled between the exterior brick-side anchor and the perforated hole.

At this time, a mesh frame tube having a plurality of discharge ports for discharging resin may be installed at the exterior brick side anchor, preferably along the longitudinal direction.

In this case, the cross-section of the mesh skeleton tube may preferably be circular.

Here, the mesh skeleton tube preferably has a plurality of skeleton frames formed at predetermined angles along the longitudinal direction, and a plurality of discharge ports are formed vertically and horizontally between the skeleton frames, so that the resin discharges and the skeleton inside the resin. All actions can be accomplished.

Additionally, a sealing injection member may be installed at the outer end of the mesh frame tube, preferably sealing the perforated hole and having an injection port through which the resin is injected into the perforated hole.

At this time, the sealing injection member preferably includes a coupling sleeve inserted into the perforated hole, a sealing plate for sealing the perforated hole, and an injection port protruding outward to inject the resin into the perforated hole, and the coupling sleeve and the injection port communicate with each other, and the coupling sleeve may be coupled to surround an end of the mesh skeleton tube.

Meanwhile, the method of constructing a seismic anchor according to the present invention using a seismic anchor for fixing exterior bricks as described above includes the steps of forming a perforated hole by drilling with a drill bit from the exposed surface of the exterior brick to a certain depth of the inner wall, and forming an anchor on the inner wall. Inserting the seismic anchor from the exterior brick side drilling hole to the inner wall side drilling hole so that it is disposed in the drilling hole formed in the inner wall, and rotating the anchor rod to insert the inner wall side anchor into the inner wall side drilling hole It includes a fixing step, a step of injecting resin into the anchor on the exterior brick side, and a step of curing the resin.

Here, the step of injecting the resin may preferably include injecting the resin into the mesh frame tube and filling the inside of the perforation hole with the resin through an outlet formed in the mesh frame tube.

In particular, the step of injecting the resin may further include sealing the perforation hole by coupling the sealing injection member to an end of the mesh framework tube before injecting the resin into the mesh framework tube.

The earthquake-resistant anchor for fixing exterior bricks and its construction method according to the present invention binds the exterior bricks and the interior wall through a combination of resin and anchor, thereby preventing the fundamental phenomenon in which anchors in the form of expansion of rigid members within conventional stone become loose over time. While solving this problem, greater fastening force can be provided, and while the installation of the anchor and the filling process of the resin are extremely simple, the phenomenon of resin overflowing and dripping can be prevented, and the filled resin can be reinforced.

The specific structural or functional descriptions presented in the embodiments of the present invention are merely illustrative for the purpose of explaining the embodiments according to the concept of the present invention, and the embodiments according to the concept of the present invention may be implemented in various forms. In addition, it should not be construed as being limited to the embodiments described in this specification, and should be understood to include all changes, equivalents, and substitutes included in the spirit and technical scope of the present invention.

Hereinafter, the present invention will be described in detail with reference to the attached drawings.

As shown in FIG. 1, the earthquake-resistant anchor for fixing exterior bricks according to the present invention includes an anchor rod 10, an inner wall side anchor 20, and an exterior brick side anchor 30.

Exterior brick (OB) corresponds to the exterior finishing material of a building, and is constructed at regular intervals against the interior wall (IW) of the building, which shares the design load of the building, to form the exterior surface of the building. Therefore, in order to install a seismic anchor for fixing exterior bricks, a process of forming a perforated hole by drilling a hole through the exterior brick (OB) and the interior wall (IW) in a straight line is first performed.

The anchor rod 10 is a member inserted into the perforated hole as shown in Figure 6a, and as shown in Figures 1 and 6b, the inner wall side anchor 20, which will be described later, is inserted into the inner wall (IW). is installed, and the exterior brick side anchor 30 is installed at the portion located on the exterior brick OB.

The inner wall side anchor 20 may include any known type of anchor as long as it expands and is fixed inside the stone when the anchor rod 10 is rotated. Therefore, the specific form of the inner wall side anchor 20 is not necessarily limited to the form shown in FIGS. 1 and 6B.

For reference, the inner wall side anchor 20 shown in FIGS. 1 and 6B is composed of an expansion tube 21, an insertion member 22, and an anti-slip nut 23, and when the anchor rod 10 is rotated, the insertion member ( 22) is inserted into the expansion tube 21 and expands the expansion tube 21, so that the expansion tube 21 digs into the inner wall (IW) and the inner wall side anchor 20 is fixed inside the inner wall.

In this case, a fastening end 11 in a polygonal shape, such as a square or hexagon, may be formed at the end of the anchor rod 10 on the exterior brick OB side, as shown in FIG. 6A, to enable easy coupling of tools. The inner wall side anchor 20 is coupled to the tip of the anchor rod 10 and is therefore located inside the inner wall IW.

As shown in FIGS. 1 and 6B, the exterior brick side anchor 30 is installed between the rear end and the front end of the anchor rod 10 and is inserted into the perforated hole formed in the exterior brick OB.

At this time, unlike the interior wall side anchor 20, the exterior brick side anchor 30 is fixed by curing a resin (E) such as epoxy filled between the exterior brick side anchor 30 and the perforated hole. Therefore, a means for injecting a resin such as epoxy, which will be described later, may be provided, and the resin injection means increases the strength and durability of the structure by interacting with the concrete inside the concrete after the resin has hardened. The bonding strength between the exterior brick-side anchor 30 and the exterior brick (OB) can be significantly increased, showing superior durability compared to anchors that expand and mechanically connect inside a typical stone.

In addition, the fastening force can be maintained for a long time even when exposed to harsh environments such as long-term vibration, seasonal temperature differences, and moisture, and unlike ordinary anchors where the fastening force is weakened due to crumbling of the joint due to earthquake vibration, a strong fastening force can be maintained. This can contribute to the seismic performance of the structure.

In particular, as shown in FIGS. 1 and 2, the earthquake-resistant anchor for fixing exterior bricks according to the present invention includes a mesh skeleton tube 31 in which a plurality of discharge holes 311 for discharging resin are formed along the longitudinal direction of the exterior brick side anchor 30. ) can be installed.

Resin (E), such as epoxy, is a liquid close to a gel state before hardening, so due to its fluidity, when it is used for purposes such as filling gaps for waterproofing purposes, it flows in and out of the construction object, forming a gap that should be airtightly filled. Problems may arise where the filling cannot be filled completely, and considerable skill may be required to concentrate filling in the necessary areas, but even in this case, in most cases, the construction area tends to flow out little by little, making it difficult to achieve a clean finish.

In this way, firstly, the area to be filled with resin (E) such as epoxy must be filled watertightly and densely, and secondly, the phenomenon of flowing down to both sides of the construction area must be prevented. .

So that these conflicting requests can be resolved simultaneously, in the seismic anchor for fixing exterior bricks according to the present invention, the mesh skeleton tube 31 having a plurality of resin discharge outlets 311 along the longitudinal direction of the body is formed, and the anchor rod 10 ) is coupled to the anchor rod (10) in a form containing, and at this time, when the resin (E) is inserted into one end of the mesh skeleton tube (31), the resin (E) is attached to the anchor rod (10) along the mesh skeleton tube (31). is injected in the longitudinal direction.

At this time, the resin (E) injected into the mesh frame tube 31 along the longitudinal direction of the anchor rod 10 is discharged to the outside of the mesh frame tube 31 through the outlet 311, so that the resin (E) is discharged to the outside of the mesh frame tube 31 through the outlet 311 before the perforated hole is filled. The leakage of the resin (E) is prevented, and the speed at which the resin (E) fills the perforated hole is controlled, allowing the resin (E) to fill the inner space of the perforated hole without any gaps.

In addition, the cross-section of the mesh skeleton tube 31 is formed in a circular shape, so that the resin (E) can be discharged evenly from the inside of the mesh skeleton tube 31 to the perforated holes in all directions, so that one part is filled first, so that the mesh skeleton tube 31 ) can be prevented from being pushed to one side.

In addition, as shown in FIG. 2, the mesh skeleton tube 31 has a plurality of skeleton frames 312 formed at certain angles along the length direction, and a plurality of discharge ports 311 are formed vertically and horizontally between the skeleton frames 312. Thus, both the discharge function of the resin (E) and the skeletal function inside the resin (E) can be achieved.

In other words, in the mesh skeleton tube 31, when the resin (E) solidifies due to the skeleton frame 312, the reinforcing bars are embedded in the concrete, dramatically improving the tensile strength of the concrete, and the resin (E) is exposed to the surrounding temperature and humidity. It can maintain solidity even if there are changes or surrounding vibrations.

Here, looking at the inner end of the mesh skeleton tube 31, as shown in FIG. 2, a blocking plate 313 is formed at the limit where the resin (E) is injected, so that the resin (E) is excessively filled and the exterior brick (OB) is formed. It can be prevented from being pushed out into the space between the inner wall (IW) and the inner wall (IW). This has the effect of reducing the waste of resin (E), neatly finishing construction, and speeding up the resin (E) injection process.

And at the outer end of the mesh skeleton tube 31, as shown in FIGS. 1 to 3, a sealing injection member 32 is formed with an injection port 323 through which the resin (E) is injected into the hole and seals the hole. ) can be installed.

More specifically, as shown in FIG. 4, the sealing injection member 32 includes a coupling sleeve 321 inserted into the perforated hole side, a sealing plate 322 that seals the perforated hole, and an external injection material to inject resin into the perforated hole. The injection holes 323 protruding are formed sequentially.

Here, the coupling sleeve 321 and the injection port 323 communicate with each other, and the coupling sleeve 321 is coupled to surround the end of the mesh skeleton tube 31. That is, the end of the mesh skeleton tube 31 is inserted into the coupling sleeve 321 and is coupled to the mesh skeleton tube 31.

In this way, the sealing injection member 32 has a coupling sleeve 321 and an injection port 323 formed on both sides with the sealing plate 322 in between, and the injection port 323 and the coupling sleeve 321 are in communication with each other, and the mesh The skeleton tube 31 is inserted into the coupling sleeve 321, so that the resin (E) injected into the mesh skeleton tube 31 through the injection port 323, as shown in FIG. 5, is inserted into the mesh skeleton tube 31. ) is first supplied to the tip side where the blocking plate 313 is formed, and is the last to reach the area where the resin overflows to the entrance of the perforated hole formed on the exposed surface of the exterior brick (OB), and the resin (E) filled up to the entrance of the perforated hole is It is prevented from flowing out due to the sealing plate 322.

As a result, the resin (E) injected into the perforated hole through the inlet 323 fills the perforated hole tightly without any waste, but does not overflow into the exterior brick (OB), enabling clean finishing construction, thanks to the inlet 323. The resin injection nozzle (N) provided in the means for injecting the resin (E) can be accurately coupled to the perforated hole to inject the resin (E) without fear of spilling to the surroundings.

Hereinafter, a method of constructing a seismic anchor according to the present invention using the above-described seismic anchor for fixing exterior bricks will be described. Most of the specific details about the seismic anchor construction method are included in the description of the seismic anchor for fixing exterior bricks described above, so overlapping descriptions will be omitted.

The method of constructing a seismic anchor according to the present invention includes the steps of forming a drill hole by drilling with a drill bit from the exposed surface of the exterior brick (OB) to a certain depth of the inner wall (IW), as shown in FIGS. 6A to 6C, and forming a hole in the inner wall (IW). A step of inserting the seismic anchor 10 from the drill hole on the exterior brick (OB) side to the drill hole on the inner wall (IW) side so that the side anchor 10 is disposed in the drill hole formed on the inner wall (IW), and anchor rod 10 ) to anchor the inner wall side anchor 20 inside the drilled hole on the inner wall (IW) side, injecting resin (E) into the exterior brick side anchor 30, and curing the resin (E). Includes steps.

Here, the step of injecting the resin (E) is the step of injecting the resin (E) into the mesh skeleton tube 31 and filling the inside of the perforated hole with the resin (E) through the outlet 311 formed in the mesh skeleton tube 31. It can be done with
