Description

  The present invention relates to a seismic reinforcement method for brick wall surfaces of a brickwork building.

  Conventionally, a building with walls built from bricks is an excellent building such as the aesthetic appearance of the brick itself with its heavy and quaint colors and textures, as well as durability, fire resistance, heat insulation, sound insulation, etc. Has performance. In these brick building structures, the brick wall surface is configured by a wet construction method in which bricks are stacked using mortar. Such a brick wall surface uses a brick with through holes in the vertical direction to insert the vertical bars, and arranges multiple vertical bars installed at appropriate intervals from the concrete foundation. The above-mentioned vertical bars and the horizontal bars arranged horizontally for each predetermined number of stacks of bricks are arranged in a lattice shape inside the brick wall surface to improve strength and earthquake resistance.

  For example, in the case where the bars are arranged only with vertical bars inside the brick wall surface, there is a “special brick and masonry method” disclosed in JP-A-53-73826 (Patent Document 1). The present invention relates to a special brick that can be reliably constructed and can form a building having sufficient strength against disasters such as storms and earthquakes, and its masonry method. A vertical through-hole for bar arrangement that penetrates in the stacking direction is opened and formed, and the bricks are joined with a mortar or other solidifying material so that the vertical through-holes overlap with each other. Is it possible to fix the bricks and reinforcing bars by pouring the binding material into the vertical through holes, and connecting the bricks together using connecting materials such as wires? Or, even if it was possible, it was not possible to arrange the bars as expected, as a wall-type reinforcing bar structure. As a result, the problem that sufficient structural strength was not obtained was solved by making it possible to insert the bars extremely effectively. And In this case, vertical reinforcement by reinforcing bars and horizontal reinforcement by connecting materials are buried in the form of a lattice in the building / structure, so it is extremely resistant to disasters such as storms and earthquakes. Buildings and structures with structures could be formed. (Refer to page 2, line 2 to line 4, page 3, line 9 to line 17, page 9, line 2 to line 12 in the specification of Patent Document 1)

  The “Brick method of building outer wall” disclosed in Japanese Patent No. 3432495 (Patent Document 2) is a brick method of building outer wall, and by building a brick wall surface by providing a space layer outside the building frame, It relates to a brick method that can improve heat insulation and durability at the same time as exterior finishing.It is located on the outside lower part of the building frame, with a horizontal plane at a predetermined distance from the outer wall, and an outer wall and a horizontal plane. Formed on the horizontal surface are bricks with through-holes in the vertical direction and stacked one after another, and the bricks located above and below are buried in the through-holes with vertical fillers and filled with filler. Each time the bricks are stacked at a certain height, they are fixed to the outer wall of the building frame with triggers combined with vertical bars, and bricks with notches reaching through holes are used for the bricks stacked on top. By stacking insert from outside the notch in the longitudinal muscle, outside the building structures it is obtained by providing the air layer so as to construct a brick wall. (Refer to paragraph Nos. 0001 and 0005 in the specification of Patent Document 2.) By configuring in this way, the space layer exhibits a heat insulating effect on the building frame simultaneously with the exterior finishing with bricks. It can be a highly efficient building. Also, the brick through-holes are filled with fillers through the vertical bars, and the bricks are fixed to the outer wall of the building frame with a trigger whenever the bricks are stacked at a predetermined height. By fixing to the building frame, a certain distance and vertical can be obtained with high accuracy, and a brick wall with excellent strength can be constructed. (See paragraphs 0019 to 0020)

  It has been shown that the vertical bars that pass through the upper and lower bricks may be single ones or short vertical bars that are added using a sleeve. (Refer to paragraph 0013 and FIG. 2) In addition, when short partial streaks are used, in the lateral direction of the stacked bricks, the strength of the brick wall surface is set so that a part of the adjacent partial streaks wraps. It has been shown to maintain. (See paragraph number 0016 and FIG. 4)

  The “brickwork building” disclosed in Japanese Patent Application Laid-Open No. 2007-284773 (Patent Document 3) is a brickwork building in which an outer wall portion of a wooden building using bricks is improved, and a wall is formed in the wooden building. Including a wall structure material, a plurality of vertical bars erected on the foundation with an interval on the outside of the wall structure material, and a brick to which the bottom brick is fixed to the foundation and the vertical bars are inserted It consists of a planar brick body (brick wall surface) formed by stacking a large number of bricks, a plurality of bar clamps fixed to appropriate portions of the wall structure material, and a plurality of horizontal bars supported by the bar brackets. Is connected to the outside of the vertical bars, and when a force is applied in the horizontal direction due to shaking or vibration during an earthquake, the vertical bricks in the planar brick body are restrained by the horizontal bars, so that Restricted movement. The horizontal streaks are sandwiched between metal tabs fixed to the wall structure material, and the planar brick body and the wall structure material are integrated. For this reason, the movement of the horizontal stripe is transmitted to the wall structure material, and the planar brick body shakes in the same direction as the wall structure material. Therefore, since the entire building is supported for shaking and vibration during an earthquake, the bricks on the wall can be prevented from collapsing. Further, a ventilation layer having a certain gap is provided between the wall structure material and the planar brick body, the ventilation layer is communicated with an underfloor space provided between the foundation and the first floor, and the outside air is By being configured to circulate through the ventilation layer and the space under the floor, the wall structure material is always in a dry state, the wall structure material is prevented from decaying, and the planar brick body supported by the wall structure material is prevented from collapsing. It is possible to make a brick building with earthquake resistance. (See paragraphs 0014 to 0016)

  JP-A-53-73826   Japanese Patent No. 3432495   JP 2007-284773 A

  By the way, in the earthquake-resistant structure of a brick building, as described in the above-mentioned patent document, the vertical and horizontal bars arranged in a lattice shape inside the brick wall surface, and the hardware of the horizontal bars and the building frame are used. Although it has achieved earthquake resistance by connection, there is no mention of construction efficiency and earthquake resistance by the arrangement method of the vertical bars on the concrete foundation. In any case, there is only a general description to the extent that it is simply planted at a predetermined interval on a concrete foundation.

  In Patent Document 1 (Japanese Patent Laid-Open No. 53-73826), reinforcing bars are planted at a predetermined interval on a concrete foundation (see line 11 to line 14 on page 6), and bricks are passed through the reinforcing bars. It is described that the holes are inserted and arranged.

  In Patent Document 2 (Japanese Patent No. 3432495), there is no description about the arrangement state of the building frame (foundation part) and the vertical bars, but according to a general technique, the building frame (foundation part) is vertically arranged. It is understood that the muscles are planted at predetermined intervals.

  In Patent Document 3 (Japanese Patent Application Laid-Open No. 2007-284773), as described in paragraph number 0019 and FIG. 4 of the publication, the vertical bars are erected on a foundation made of concrete with an appropriate interval. It is described that the lower end portion of B is bent in an L shape to prevent detachment from the foundation, and is inserted through the hole of the brick from the upper end. As a result, it can be seen that all the vertical bars erected on the foundation at appropriate intervals are embedded in the foundation and erected.

  As described above, all the vertical bars are embedded and arranged at a predetermined interval at the same time as placing the foundation of the concrete. Since it is embedded in the foundation, it is desirable in terms of earthquake resistance. However, in this case, from the pitch including the joints of the bricks at the design stage, the distance between the vertical stripes on the concrete foundation is calculated and a drawing is created. The subtle deviation from the design drawing often occurs. In addition, since bricks are fired at high temperature, the finished dimensions are not necessarily the same, and it is practically extremely difficult to construct according to the drawings, but it is a problem in constructing the brick wall surface, The impact on costs is reflected in a significant way.

  In addition, the difference in the joint spacing between bricks and the individual differences in the dimensions of the bricks are piled up, resulting in a large displacement, and the vertical bars arranged at a predetermined interval are aligned with the positions of the brick through holes. The size of the brick through hole is increased or the brick is notched, and the size is forced to be adjusted.

  In addition, since the brick wall surface assembly using the conventional bar arrangement method repeats the work performed when the bricks are sequentially inserted from the upper end of the long vertical bars, the following problems are present.

  The problem is that it takes a lot of time and effort, and the construction period naturally increases and construction costs inevitably increase. There are concerns about accidents such as inadvertently dropping a brick from above, and there are issues in construction safety. Brick and reinforcement are fixed with mortar, but the surface of a general reinforcement material is a smooth surface with some unevenness, so the stress applied to the fixed part of the mortar and reinforcement in the event of an earthquake The problem is that the strength of the brick wall cannot be maintained due to peeling of the bar arrangement. Because the surface of general reinforcement is not rust-proofed, the mortar and reinforcement are naturally peeled off due to mortar moisture and corrosion due to aging, and the strength of the brick wall surface cannot be maintained. .

  In Patent Document 2, it is shown that short vertical stripes are added by using a sleeve, but since it is press-fitting or caulking using a crimping tool, it is merely a simple fixing method. There is a problem that the strength is inferior.

  In view of the above-described problems, the present invention aims to provide a method for seismic reinforcement of a brick wall surface of a brick masonry building that achieves improvement in construction efficiency and construction safety and is excellent in earthquake resistance and durability. And

  In the concrete foundation, a plurality of vertical bars erected at a predetermined interval are inserted into a plurality of vertical holes penetrating in the vertical direction of the brick, and the horizontal bars are arranged for each appropriate number of stacking stages of bricks. In the brick wall surface arrangement method for a brick building, in which the horizontal bars are connected to the building frame using attachment hardware, the corner portion of the foundation has a short full-length bolt anchor with a lower end bent in an L shape. It is configured to be able to extend further upward by connecting a short full length screw bolt vertical thread using a connecting nut and embedding the line, and on the upper surface of the straight line part other than the corner part of the foundation An anchor nut placed at a predetermined interval, and the anchor nut is erected by screwing the short length of all screw bolt vertical bars, and the short length of the screw bolt vertical bars using the connecting nut. Screwing Is further solved by the extended configured to be capable of upward by sintering.

  In addition, the screwed and connected positions of the all screw bolt vertical bars standing on the foundation at predetermined intervals are alternately shifted so as not to coincide with the adjacent all screw bolt vertical bars. Is solved.

  In addition, horizontal stripes connected with the building frame and mounting hardware are arranged on the upper surface of the bricks assembled under the window frame opened in the brick wall surface, and further protruded from the upper surface of the bricks assembled under the window frame A threaded portion provided in the vertical direction of the T-type nut is screwed and connected to the tip of the vertical thread of all the screw bolts, and a horizontal line is inserted through a through-hole provided in the horizontal direction of the T-type nut. Then, the horizontal streak inserted through the T-type nut and the through hole is covered with a concave portion on the bottom side of the brick under the window from above and fixed by filling with mortar.

  Furthermore, the all-threaded bolt longitudinal bar, the all-threaded bolt anchor longitudinal bar, the transverse bar, the connecting nut, the T-nut, the anchor nut, the mounting hardware, or a plurality of or all of them combined It is solved by applying hot dip galvanization.

  In claim 1, a plurality of vertical bars erected on a concrete foundation at predetermined intervals are inserted into a plurality of vertical holes penetrating in the vertical direction of the brick, and for each appropriate number of stacking steps of bricks. In the brick wall surface layout method for a brick building, in which horizontal bars are arranged and the horizontal bars are connected to the building frame using mounting hardware, the lower end portion of the corner portion of the foundation is bent in an L shape. The short vertical screw bolt anchor vertical stripes are embedded and set up, and the short full screw bolt vertical stripes are screwed together using a connecting nut so that they can be extended further upward. On the upper surface of the straight portion, there are provided anchor nuts that are driven at a predetermined interval, and the anchor nuts are vertically installed by screwing the short vertical threaded vertical bars, and using the connecting nuts, The whole Further, since the extended configured to be capable of upward by screwing connecting Jiboruto longitudinal muscle were achieved the following effects.

  In the corner portion of the foundation, a short full screw bolt anchor vertical stripe whose lower end is bent in an L-shape is embedded, and the short full screw bolt vertical stripe is screwed and connected using a connection nut. In addition to being able to extend further upward, all screw bolts are erected at the corners of the foundation, which are particularly affected by shaking during earthquakes, coupled with the fact that the thread of the all-screw bolt anchor vertical bar and the concrete are firmly fixed. Improved pull-out strength of anchor vertical bars.

  An anchor nut driven at a predetermined interval is provided on the upper surface of the straight portion other than the corner portion of the foundation. The anchor nut is erected by screwing a short length of all screw bolt vertical bars, and a connecting nut is provided. Because it is configured to be able to extend further upward by screwing and connecting all the short bolt vertical bars, anchor nuts are placed on the upper surface of the foundation according to the state of brick laying on the upper surface of the straight portion of the foundation It is possible to stand up by screwing all the vertical threads of the bolts, and it is easy to cope with the difference caused by individual differences in the finished dimensions of the bricks and the difference in the subtle spacing of the joints between the bricks. Realized the improvement.

  Since all the threaded bolt vertical bars are short, they are assembled while inserting the vertical holes of the bricks at the upper end of all threaded bolts that can be easily reached at the time of construction. At the approaching stage, it is extremely safe and highly efficient to repeat the construction of the brick wall surface by repeating the construction of connecting and extending the lower end of the next full thread bolt vertical bar with a connecting nut and stacking the bricks further. Realized to build up.

  In addition, the short full-length bolt vertical bars provide the desired strength as a single vertical bar inside the brick wall, and the mortar as the fixing material filled in the vertical holes of the bricks is firmly fixed to the threads. By doing so, peeling of both was prevented, and it was realized to constitute a strong brick wall surface excellent in earthquake resistance.

  In addition, short full-length bolt bolts should be cut to any size depending on the height of the brick wall surface and the window frame installed in the middle of stacking, or connected by screwing the connecting nuts. As a result, no material was wasted and construction efficiency was improved.

  In addition, short full-length bolt bolts are delivered to the construction site not by long body trucks for loading long objects as in the past, but by small vehicles such as short body trucks and one-box vans. It is possible to carry out the vehicle in a narrow road and easy to handle, so that it can be handled very safely. Improvements have also been realized.

  According to a second aspect of the present invention, the positions of the threaded bolt vertical bars that are erected on the foundation at predetermined intervals are alternately connected so that they do not coincide with the adjacent threaded vertical bars. Because the load due to the shaking at the connecting position of the connecting nuts of all the screw bolt vertical bars in the event of an earthquake is distributed over the entire surface of the brick wall, the brick wall surface with more stable strength can be obtained. Made it possible to provide.

  In Claim 3, the horizontal stripe connected with the building frame and the attachment hardware is arrange | positioned on the upper surface of the brick assembled under the window frame opened to the brick wall surface, and also the brick assembled under the window frame is arranged. A threaded portion provided in the vertical direction of the T-type nut is screwed and connected to the tip of the vertical thread of the entire threaded bolt protruding from the upper surface, and a horizontal line is inserted into the through-hole provided in the horizontal direction of the T-type nut. The horizontal bars inserted through the T-nuts and the through-holes are covered with the bottom-side recesses of the bricks under the window from above and fixed by filling with mortar. Unlike the case where the vertical bars protruding on the upper surface of the bricks are not cut, the horizontal bars are connected to the building frame by the mounting hardware at the lower part of the window frame of the building frame, and the T-nuts are arranged. Fill the horizontal lines with mortar and bricks under the window. By the brick wall of the window frame lower part while being rigidly coupled to the building structures, and realize improvement of vibration resistance.

In claim 4, the all-thread bolt vertical bar, the all-screw bolt anchor vertical bar, the horizontal bar, the connecting nut, the T-type nut, the anchor nut, the mounting hardware, or a plurality of combinations thereof, Or, all have been hot dip galvanized to prevent cracking of bricks and joint mortars caused by expansion caused by rust and corrosion generated in the bar interior, and meet the high durability of brick masonry buildings The durability of the vertical bars is realized, and it is possible to make the brick wall surface extremely excellent in earthquake resistance and durability comprehensively.

  A first embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a front view of a brick building, and FIG. 2 is a view showing a bar arrangement state inside the brick wall surface (1) of FIG. In the present invention, the brick wall seismic reinforcement method is applied to a conventional wooden construction method.

  3 is a longitudinal cross-sectional view of the brick wall surface, FIG. 4 is an enlarged view of a portion A in FIG. 3, and FIG. 5 is an enlarged cross-sectional view along the line BB in FIG.

  First, the structure of the brick wall surface (1) and the building frame which consists of a wooden conventional construction method of the brick building constructed in this way is demonstrated using FIG. 3 thru | or FIG.

As shown in FIGS. 3 to 5, a building frame made of a conventional wooden construction method is formed as a structure inside the brick wall surface (1) of the brick building. The building frame includes a base (6a) connected to a rising portion of a concrete foundation (5), and a column (6b) and an intermediary column (6c) provided at predetermined intervals above the foundation (6a). In addition, the interior material (7a) made of gypsum board or the like is affixed to the indoor side of the stud (6c), and moisture on the wall is actively discharged outdoors to prevent condensation in the wall. A wall is formed by attaching a moisture-permeable waterproof sheet (7b). And on the outdoor side of this wall body, a brick wall surface (1) is comprised via a ventilation layer (8), and it is comprised as a brick masonry building.

  FIG. 6 is a view showing a bar arrangement state to a concrete foundation (5), and FIG. 7 is a plan view thereof. The applicant paid attention to the fact that the stress due to the shaking of the earthquake has a particularly strong influence on the corner portion in plan view of the concrete foundation (5) of the brick building. The present embodiment is characterized in that, in particular, a method of arranging vertical bars standing from the upper surface of the foundation (5), and the vertical bars are all screw bolt vertical bars (2a) and screwed and connected by a connecting nut (2b). Is. That is, the concrete portion (5) in a plan view has different corner portions (four locations in the case of a square shape in plan view) and the arrangement method of all screw bolt vertical bars (2a) other than the corner portions, By making the vertical bars short screw bolts, the brick wall surface (1) is further improved in earthquake resistance, construction efficiency and construction safety. In addition, although the corner part is shown in the drawing as the protruding corner part, the corner is also included in the definition of the corner part. This will be described in detail below.

  As shown in FIG. 6 and FIG. 7, the concrete foundation (5) is formed with the total length of the vertical bars (2d) of the corners of the corner portion of the concrete foundation (5) and the adjacent three vertical bars as the total thread bolt anchor longitudinal bars (2d). At the same time, it is embedded and fixed. The vertical thread (2d) of all screw bolt anchors is firmly fixed to the concrete foundation (5) at the same time as its lower end is bent in an L shape and has a thread on the surface. Realized to improve the pull-out strength due to shaking.

  In addition, anchor nuts (2c) are placed at predetermined intervals on the upper surface of the straight portions other than the corner portions of the concrete foundation (5), and all the screw bolt vertical bars (2a) are screwed into the vertical portions. Set up. As a result, anchor nuts can be placed on the top surface of the foundation in accordance with the laying status of the bricks, and all the threaded bolt vertical bars can be screwed upright, so individual differences in the finished dimensions of the bricks and the joints between the bricks The construction efficiency was improved by easily dealing with deviations caused by subtle differences in spacing.

  Further, the short full thread bolt vertical bar (2a), which is an important element of the features of the present embodiment, is configured by screwing and connecting using a connecting nut (2b). As a known example in which short vertical bars are connected by connecting short vertical bars, Patent Document 2 shows that the short vertical bars are extended using a sleeve, but in this embodiment, the vertical bars are all short screw bolts. By using the vertical bars, various problems including improvement of earthquake resistance were solved. The all screw bolt means a bolt whose entire length in the longitudinal direction is a screw. In addition, the short length is not particularly limited in length, but it may be a length that can solve the problem in the case of construction with a single through-long vertical line, and then the builder works up. The length should be within a length that can be easily reached when stretched (approximately within 180 cm).

  Inside the brick wall surface (1), all screw bolt vertical bars (2a), all screw bolt anchor vertical bars (2d), and horizontal bars (3) are arranged in a lattice pattern. The all screw bolt vertical bars (2a) and the all screw bolt anchor vertical bars (2d) are erected from a predetermined position of the foundation (5), and are screwed together by the connecting nut (2b). By connecting and extending upward, it is finally configured with a desired strength as a single long through vertical line.

  In this way, the vertical bars are the short total screw bolt vertical bars (2a) and the total screw bolt anchor vertical bars (2d), so that the brick (1a) is the total screw bolt vertical bars (2a) and the total screw bolt anchor vertical bars (2d). ) Through the vertical holes (1b) of the bricks (1a) sequentially from the top end of the bricks (1a), and the stacked bricks (1a) are placed on the top ends of the total screw bolt vertical bars (2a) or the total screw bolt anchor vertical bars (2d). When reaching or approaching, the connecting nut (2b) is screwed and connected to the lower end of the next all-threaded bolt vertical bar (2a), and the work of further stacking bricks (1a) is repeated. The strength of the brick wall surface (1) is improved by making sure that the reinforcement (2a) and the full thread bolt anchor vertical reinforcement (2d) can be obtained as a single vertical stripe inside the brick wall surface (1). It was realized. In addition, because it is short, there is an upper end of all the threaded bolt vertical bars (2a) at a height that can be reached sufficiently, so that it is possible to stack bricks easily and safely in a short time, thus improving construction efficiency.

  Also, the short full screw bolt vertical stripe (2a) and the full screw bolt anchor vertical stripe (2d) are cut into arbitrary dimensions according to the height of the brick wall surface (1) and the situation of the window frame arranged in the middle of stacking. Then, the connecting nut (2b) is screwed and joined from there, and the material is not wasted, thereby reducing the cost and improving the construction efficiency.

  Further, since the vertical hole (1b) of the brick (1a) through which the total screw bolt vertical bar (2a) and the total screw bolt anchor vertical bar (2d) are inserted is filled with mortar as a fixing material, the total screw bolt vertical bar ( 2a) Threads of all threaded bolt anchor vertical bars (2d) and mortar (9) are firmly fixed to prevent separation of both, and it is possible to constitute a strong brick wall surface with excellent earthquake resistance It was.

  In addition, since all the screw bolt vertical bars (2a) and all screw bolt anchor vertical bars (2d) are short, delivery to the construction site is not a long body truck for loading long objects as in the past, It can be delivered by small vehicles such as short body trucks and one-box vans, and when loaded, it does not stick out in the longitudinal direction of the vehicle like a long reinforcing bar, and it can be handled even in narrow roads. Since it is easy to carry out, extremely safe delivery is possible, and cargo handling is improved.

  Next, the horizontal stripe (3) will be described. As described above, on the brick wall surface (1), all screw bolt vertical bars (2a) and all screw bolt anchor vertical bars (2d) are arranged, and the horizontal bars (3) are appropriately provided for each number of steps (in FIG. 2 and FIG. 6). In this case, the bars are arranged every 5 steps) and connected to the building frame by the mounting hardware (4). At this time, since the horizontal bars (3) are arranged so as to be located in front (outside of the room) of the vertical bars (2a), the brick wall surface (1) suppresses the collapse to the outside due to the shaking of the earthquake. Configured as follows.

  8 and 9 are explanatory views of the mounting hardware (4) described above. FIG. 8A is a front view, FIG. 8B is a left side view, and FIG. 8C is a plan view showing a holding state of the horizontal stripe (3). FIG. 9 is a detailed explanatory view of the mounting hardware (4), and shows that two mounting hardwares are connected at the end portions and bent and overlapped. The mounting hardware (4) holds the mounting portion (4b) having a screw hole (4a) for mounting on the building frame, the stay portion (4c) for arranging the horizontal bar at a position separated from the building frame, and the horizontal bar. It is comprised from the holding | maintenance part (4d) for. The mounting hardware (4) configured as described above is fitted in the horizontal line (3) disposed on the brick (1a) in an open state as shown in FIG. 9, and is indicated by an arrow in FIG. 8 (B). As described above, the horizontal stripe (3) is configured to be held movably in the front-rear direction.

  As described above, the brick wall surface (1) fixed to the building frame by the mounting hardware (4) is held so that the horizontal bars (3) are movable in the front-rear direction by the holding portion (4d) of the mounting hardware (4). Therefore, the shaking of the building frame during the earthquake is absorbed and relaxed by the holding portion (4d), and the seismic strength of the brick wall surface (1) is improved. Moreover, since the horizontal bar (3) is arranged so as to be located in front (outside of the room) of the vertical thread bar (2a), the brick wall (1) is prevented from collapsing outward and has excellent earthquake resistance. Realized.

  In FIGS. 2 and 6, the horizontal stripes (3) are arranged on the brick (1a) at intervals of five stages. It suffices to arrange them at intervals. For example, in the vicinity of the roof where the influence of shaking is greatest in the event of an earthquake, the horizontal stripes (3) may be arranged at fine intervals such as every two steps or every three steps, and the intervals may be made rougher as going downward. is there.

  The ventilation layer (8) raises the moisture in the wall discharged from the moisture permeable waterproof sheet (7b) of the building frame by convection generated in the ventilation layer (8), and is not shown but is provided under the eaves. The durability of the building is improved by discharging from the exit and preventing the generation and decay of the building. Furthermore, by opening a part of the vertical joint of the brick (1a) in the foundation part of the brick wall surface (1) without filling with mortar, the outside air introduction into the ventilation layer (8) is promoted, The effect of preventing moisture further and making it easier for water droplets such as rain entering the brick wall surface (1) to escape to the outside occur.

  A second embodiment will be described with reference to FIG. A feature of the second embodiment is that a connecting nut (2b) of all threaded bolt vertical bars (2a) and all threaded bolt anchor vertical bars (2d) erected on the foundation (5) at a predetermined interval. The positions of the threaded joints are alternately shifted so as not to coincide with each other in the horizontal direction of all screw bolt vertical bars adjacent in the lateral direction.

  For example, when the length of one full thread bolt vertical bar (2a) and the total thread bolt anchor vertical bar (2d) is 100 cm, the connecting nut (2b) is also arranged every 100 cm. In this case, the threaded connection positions of the adjacent thread bolt vertical bars (2a) at the connection nut (2b) are shifted in the horizontal direction up or down by 50 cm, which is a half length, and are alternately arranged. As a result, it is possible to disperse the load on the threaded connection portion of the connection nut (2b) due to the shaking of the earthquake over the entire surface of the brick wall surface (1), and more stably maintain the seismic strength of the brick wall surface (1). It became possible to do.

  A third embodiment will be described with reference to FIGS. FIG. 10 is an enlarged view of the window frame portion on the second floor in FIG. 2, and FIG. 11 is a diagram showing in detail the headboard (6d) of the window frame and the bar arrangement located below it. 12 is an enlarged view of a portion A in FIG. 11, and FIG. 13 is an enlarged sectional view taken along line BB in FIG.

  The feature of the third embodiment is that the strength of the opening portion of the brick wall surface (1) such as the window frame or the window is improved by using the T-shaped nut (21). Generally, the vertical streaks of the brick (1a) stacked immediately below the headboard (6d) under the window frame are in a state where the upper end portion is slightly protruded from the brick immediately below the headboard (6d). In particular, the ends of the adjacent vertical bars are not fixed to each other. For this reason, the individual bricks (1a) connected in the left-right direction directly below the headboard (6d) are simply fixed by the mortar (9) and do not necessarily satisfy the earthquake resistance.

Therefore, as shown in FIG. 10 to FIG.
On the upper surface of the brick (1a) connected directly below the coping (6d) under the window frame, a horizontal bar (3) connected to the building frame and the mounting hardware (4) is arranged, and further assembled under the window frame. The threaded portion (21a) provided in the vertical direction of the T-shaped nut (21) is screwed and connected to the front end of the vertical threaded bar (2a) protruding from the upper surface of the stacked brick (1a). A horizontal streak (3) is inserted through a through hole (21b) provided in the horizontal direction of the T-shaped nut (21), and is inserted into the T-shaped nut (21) and the through-hole (21b). Since the horizontal stripe (3) is covered with the bottom side concave portion of the brick under the window (11a) from above and filled with the mortar (9), the horizontal stripe (3) is attached to the fitting ( 4) Connected to the building frame by means of the horizontal bars (3) arranged on the T-shaped nut (21) By a window under the brick (11a) and fixed by filling the mortar (9), brick walls of the window frame lower portion (1) together with the firmly connected to the building structures, and realize improvement of vibration resistance.

  In FIGS. 10 to 13, the T-shaped nut (21) is applied to the brick (11 a) just below the headboard (6 d) below the window frame, but it can be effectively applied to the upper part of the window frame. Is possible.

  A fourth embodiment will be described. The feature of this embodiment is that the entire threaded bolt vertical bar (2a), the total threaded bolt anchor vertical bar (2d), the horizontal bar (3), the connecting nut (2b), the T-shaped nut (21), the anchor nut ( 2c), any of the mounting hardware (4), or a plurality or all of them combined, are hot dip galvanized.

  This prevents cracks in the brick (1a) and joint mortar (9) caused by expansion due to rust and corrosion that tends to occur in the bar wall (1), and is highly durable for brick masonry buildings. It is possible to provide a method of seismic reinforcement for brick wall surfaces of brick buildings, which realizes durability of reinforcement according to the characteristics and comprehensively has excellent earthquake resistance and durability.

  In hot-dip galvanizing, unlike coating and electroplating, zinc and iron are strongly bonded by an alloy layer formed between zinc and iron, so plating does not peel off over many years. . In hot dip galvanizing, a zinc oxide film is provided on the surface by immersing the steel material in molten zinc, which prevents the generation of rust with a stable property that prevents the passage of air and water.
