Description

{Masonry structures using triaxis holder unit for seismic reinforcement and construction method of the same}

The present invention relates to a stucco brick structure for seismic reinforcement and a construction method therefor, in particular, a horizontal release iron wire disposed at a horizontal joint at a certain height and a vertical release iron wire passing through a brick hole of a stucco brick are combined with a three-axis holder unit and newly established. It relates to a stucco structure using a three-axis holder unit so that the seismic reinforcement of the stucco structure is made, and the seismic reinforcement is also made at the top of the opening of the stucco structure.

Generally, a stucco structure forms a masonry wall made by stacking bricks, concrete blocks, etc. on the outside of a wall (inner wall). In order to have a seismic resistance, the bonding force between the inner and outer walls is very important. Due to the compositional characteristics of the masonry, which is constructed by stacking bricks one by one, there is no way to secure the integrity such as a rim beam, so it is very vulnerable to lateral loads, resulting in conduction and collapse. The fall of the masonry walls (deformation out of the surface) is the most fatal phenomenon that occurs in the masonry structures due to earthquakes. It is a deformation that is difficult to resist as a masonry wall that is vulnerable to bending stress (tensile force) by causing the force to fall over the wall by acting in a vertical direction rather than in the wall direction, leading to rapid collapse of the entire structure. Therefore, it is necessary to consider from the planning of the masonry structure to prevent fall and collapse.

As a background technology of the present invention, as Korean Registered Patent Registration No. 10-1371098 (Patent Document 1), a masonry wall reinforcement structure has been proposed. This is to increase the bonding strength of the masonry wall, which is composed of an inner wall, an insulating material, and an outer wall by simple construction using a fixed member and a release iron wire, thereby increasing the life and rigidity of the masonry wall. However, the background art has a longer installation process due to the work of fixing the fixing member to the wall, the assembling of the vertical release iron wire having the primary and secondary cross-connections to the fixing member, and the fixing member is complicated, resulting in workability. Falls. In addition, since the vertical release iron wire has a primary and secondary cross connection, there is a problem in that the bending stiffness decreases.

After stacking stucco 14, install 3-axis holder unit 20

First, as shown in FIG. 5A, the stucco bricks 14 are stacked on the outside of the wall 12, and between the stuccos 14 and 14 placed on the same horizontal surface at regular intervals along the periphery each time a predetermined height is reached. The three-axis holder unit 20 is installed upward.

The three-axis holder unit 20 is a horizontal holder (21) placed in the horizontal direction (X direction), as shown in Figure 4, a pair of vertical holders (22) joined in the vertical direction (Z direction) to the horizontal holder 21 , 22a), which is joined to the horizontal holder 21 in a right angle direction (Y direction) and is composed of a fix holder 23 installed between a pair of vertical holders 22 and 22a.

The horizontal holder 21, the pair of vertical holders 22 and 22a and the fix holder 23 have the same helical structure in the hollow section. For example, the horizontal holder 21 has six spiral grooves 211 on its inner circumferential surface.

As such, the horizontal holder 21, the pair of vertical holders 22, 22a, and the fix holder 23 have the same six helical groove structures, and thus, a pair with the horizontal release iron wire 31 inserted into the horizontal holder 21. Vertical release iron wire 32 is inserted into any one of the vertical holder (22,22a) has a cross-section of any one of the two-sided, three-sided, six-sided cross-section and spirally coupled.

In this embodiment, the horizontal holder 21 and the pair of vertical holders 22 and 22a have a length smaller than the diameter of the brick hole 14a, and the fix holder 23 has a length larger than the diameter of the brick hole 14a. Although installed, the 3-axis holder unit 20 is not limited to this length.

On the other hand, the fix 33 inserted into the fix holder 23 has a substantially triangular cross section as shown in (a) and (b) of FIG. 10, or a wing every 180 degrees as shown in (c). 331) and may be helical structures each twisted in a spiral. As such, the fix 33 is installed with a twisted helical structure, and is penetrated without damage when passing through an insulating material (not shown) installed between the wall 12 and the stucco structure 100, so that clean construction is possible.

Installation of vertical release wire (32)

Then, as shown in FIG. 5, the vertical release iron wire 32 is inserted into any one of the pair of vertical holders 22 and 22a on the 3-axis holder unit 20 side, and the bricks 14a of the stacked brick 14 are stacked. Position. The vertical release iron wire 32 has a triangular cross section and is spirally twisted as shown in FIG. 10(d).

As such, the vertical release iron wire 32 is located in the brick hole 14a of the stacked stucco 14 and is synthesized through the stucco 14 and mortar. Therefore, the laminated stucco bricks 14 are bound to each other via the vertical release iron wire 32 to exhibit the integrity behavior with the wall 12 to resist earthquake resistance.

Installation of horizontal release iron wire (31)

Then, as shown in FIG. 6, the horizontal release iron wire 31 is rotated and inserted into the horizontal holder 21 on the 3-axis holder unit 20 side.

At this time, the horizontal release iron wire 31 has the same structure as the horizontal holder 21, but may be arranged to be connected to the same straight line through a horizontal joint holder 41 having a longer length. That is, the horizontal release iron wire 31 has a triangular cross section and is spirally twisted as shown in FIG. 10(d). Therefore, by connecting the entire circumference of the stucco structure 100 with a horizontal release wire 31, the stucco structure 100 is connected to the wall 12 through a fix 33, which will be described later, to secure the integrated behavior during the earthquake. can do.

Subsequently, the horizontal release wire 31 may be additionally coated with silicone (S2) on the back surface of the horizontal release wire 31 and then filled with a non-shrinking mortar (M) to finish. Here, silicon (S2) serves as a shock absorber in the event of an earthquake.

Installation of fix (33)

Then, as shown in FIG. 7, the fix 33 is inserted into the fix holder 23 on the side of the 3-axis holder unit 20 by rotational coupling, and then inserted into the wall 12 side. The installation of the fix 33 may use an electric drill. As such, when the front end of the fix 33 is rotated through the wall 12, the rear end maintains a helical engagement state with the fix holder 23, so that the fix holder 23 is not likely to be detached from the fix 33.

Thereafter, the operation of filling the silicon S1 between the gap between the fix holder 23 and the fix 33 may be performed. Silicon (S1) performs shock absorption during the arrival of an earthquake between the gap between the fix holder 23 and the fix 33.

According to the construction method as described above, the 3-axis holder unit 20 is installed for each predetermined stacking height of the stucco brick 14, and the vertical release wire 32 and the horizontal release iron wire 31 are installed in the 3-axis holder unit 20. After inserting and joining, finally, the fixation 33 is more firmly connected to the fixation 33 by integrating the fixation 33 into the wall 12 through the three-axis holder unit 20, thereby being integrally connected to the fixation wall 33. By doing so, the earthquake-resisting wall 12 and the stucco structure 100 perform an integral action, thereby preventing the stucco structure 100 from falling, breaking, and collapsing.

At this time, the three-axis holder unit 20 can be realized by uniformly seismic reinforcement of the overall stucco structure 100 by being installed in a grid arrangement in the stucco structure 100 as shown in FIGS. 8 and 9.

On the other hand, in the present method, as shown in FIG. 9, the additional step of installing the fix 33 in the center of the lattice area of the stucco brick structure 100 and driving it into the wall 12 side is additionally performed, thereby seismicizing the stucco structure 100. The reinforcement can be further increased.

On the other hand, in order to reinforce the top of the opening 101 of the stucco structure 100 in the present invention, as shown in FIGS. 11 to 13, inserted into the stucco 14 arranged side by side at the top of the opening 101 Release reinforcing bar (51) for opening reinforcement, and vertical joint release bar (52), which is located at the vertical joint between stucco bricks (14 and 14) at regular intervals and spans the opening reinforcing bar (51), It is configured to further include a reinforcing bar tightening nut 53 that is inserted into the vertical joint reinforcing bar 52 to fix the reinforcing bar 51 for reinforcing the opening to the stucco 14.

Here, the opening 101 may be an open area where windows or doors are installed. The vertical joint reinforcing bar 52 has a structure in which a triangular cross-section is substantially twisted as shown in FIG. 10(d).

In order to have such a structure, in this construction method, the stucco brick 14 is arranged side by side so that the center axis direction of the brick hole 14a is horizontal at the top of the opening 101 of the stucco structure 100 as shown in FIGS. 11 and 12, After inserting the reinforcing bar reinforcement 51 for opening reinforcement into the brick hole 14a of each stucco brick 14, the vertical joint release reinforcing bar 52 is positioned at a vertical joint between the stucco bricks 14 and 14 at a predetermined interval. Let the lower hook (521) of the lower part of the release reinforcement 51 for reinforcing the opening as shown in FIG.

Thereafter, the release joint reinforcing bar 53 is fixed to the stucco brick 14 by rotationally tightening the release reinforcing bar tightening nut 53 to the vertical joint reinforcing bar 52.

Here, as shown in Figure 14, the reinforcing bar tightening nut 53 is a plate-shaped triangular hole 531 and a triangular hole 531 penetrating with a triangular shape in the thickness direction so that the vertical joint reinforcing bar 52 is inserted in the center. A wedge groove 532 for preventing reverse rotation is formed on at least one side.

Therefore, after rotationally tightening the release bar tightening nut 53, it is possible to prevent the release of the release bar tightening nut 53 by forcibly inserting the wedge 55 into the wedge groove 532 for preventing reverse rotation.

After the rotational tightening of the release reinforcing bar tightening nut 53 as described above, as shown in FIGS. 12A and 12B, the cross holder unit 60 and the horizontal release wire 31 may be further installed. That is, after performing the rotational tightening of the release bar tightening nut 53, insert the vertical holder 61 of the cross holder unit 60 into the vertical joint release bar 52, and the horizontal holder of the cross holder unit 60 62) may have a step of inserting the horizontal release wire 31. Here, the cross holder unit 60 has a structure in which the vertical holder 61 and the horizontal holder 62 are cross-shaped with each other and joined by mutual welding as shown in FIG. 12A.

As described above, the horizontal release iron wire 31 is installed on the side of the stucco brick 14 disposed at the upper end of the opening 101 through the cross holder unit 60 to further enhance the reinforcement.

Thus, during the masonry of the stucco 14, the release reinforcement 51 for reinforcing the opening is inserted into the stucco 14 disposed at the top of the opening 101 to the upper end of the opening 101 to the vertical joint release reinforcement 52. It is firmly bound. In addition, the upper portion of the opening 101 is coupled to the vertical joint release bar 52 and the horizontal release wire 31 through the three-axis holder unit 20 to effectively resist earthquake resistance.
