Description

[Technical Field]

[0001] The present invention relates to an external seismic reinforcement device and a method for installing the external seismic reinforcement device. [Background technology]

[0002] The Building Standards Act was revised in 1981, and it has been reported that buildings constructed after the new Building Standards Act came into effect suffered relatively little damage in subsequent major earthquakes (such as the Hyogo Prefecture Southern Earthquake of 1995). However, there are still many buildings that were constructed before the new Building Standards Act came into effect and have poor earthquake resistance, and technologies related to earthquake reinforcement have been devised to improve the earthquake resistance of these buildings.

[0003] Conventionally, a known technology for earthquake-resistant reinforcement of buildings is disclosed, for example, in Patent Document 1. The external earthquake-resistant reinforcement device disclosed in Patent Document 1 (hereinafter referred to as "prior art") is composed of multiple (two) basic frames (see FIG. 4 of Patent Document 1). The length of the basic frame in the longitudinal direction is approximately half the length corresponding to the height from the foundation to the beams of the building. The basic frame is provided with diagonal braces (see FIG. 1 of Patent Document 1), and therefore has stronger earthquake resistance than larger frames. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Registration No. 3135115 Summary of the Invention [Problem to be solved by the invention]

[0005] However, when a basic frame with a robust structure as in the prior art is used, the rigidity is increased, so it was necessary to prevent this from affecting the framework of the building (foundation, beams, columns, etc.).

[0006] Furthermore, since conventional technology typically requires multiple basic frames, there is a need for further weight reductions to make it easier to transport multiple basic frames to the construction site for seismic reinforcement and to improve workability during construction.

[0007] Furthermore, because the height of columns in buildings constructed before the enforcement of the new Building Standards Act is slightly higher than the height of columns required by the new Act, conventional techniques manufactured in accordance with the new Act could have resulted in insufficient height, which could have affected the workability of construction work related to earthquake reinforcement.

[0008] The present invention has been made in consideration of the above-mentioned circumstances, and aims to provide an external earthquake-resistant reinforcement device that does not affect the framework of a building (foundation, beams, columns, etc.) and that improves workability when transporting and installing the basic frame compared to conventional technology, as well as a construction method for this external earthquake-resistant reinforcement device. [Means for solving the problem]

[0009] (1) The external earthquake-resistant reinforcement device of the present invention, which has been made to solve the above-mentioned problems, is a device that is attached to the outside of the wall of the building by connecting multiple basic frames, each of which has a frame body having a pair of vertical frames extending in the height direction of a column joined between the foundation and beam of the building, an upper frame connecting one end of each of the vertical frames, and a lower frame connecting the other end of each of the vertical frames, and a pair of diagonal braces arranged so as to cross each other inside the frame body, and is characterized in that the diagonal braces are formed so that one end side and the other end side in the longitudinal direction are thinner than approximately the middle part in the longitudinal direction.

[0010] According to the present invention having the feature (1) above, the diagonal braces are formed so that one and the other longitudinal ends are thinner than the respective longitudinal intermediate portions, resulting in a lower rigidity than the diagonal braces of the prior art. This prevents the diagonal braces from affecting the framework (foundation, beams, columns, etc.) of a wooden building, for example. Furthermore, according to the present invention, the diagonal braces are formed so that one and the other longitudinal ends are thinner than the respective longitudinal intermediate portions, resulting in a smaller size than the diagonal braces of the prior art. This allows the basic frame to be lighter than the prior art.

[0011] (2) Furthermore, in the external earthquake-resistant reinforcement device of the present invention, in the invention described above in (1), mounting portions for attaching the basic frame to the wall may be formed on the inside of each of the vertical frame, the upper frame, and the lower frame, and the mounting portions may be formed separately from each other.

[0012] According to the present invention having the feature (2) above, the mounting portions of the vertical frame, upper frame, and lower frame are formed separately from one another, which reduces the rigidity of the corresponding portions compared to the configuration in which the mounting portions are continuous, as in the prior art. This prevents any impact on the framework (foundation, beams, columns, etc.) of a wooden building, for example. Furthermore, according to the present invention, as described above, the mounting portions are formed separately from one another, which allows the basic frame to be lighter than the configuration in which the mounting portions are continuous, as in the prior art.

[0013] (3) Furthermore, in the external earthquake-resistant reinforcement device of the present invention described in (1) or (2) above, one of the diagonal braces may have one longitudinal end joined to one end of one of the vertical frames and the other longitudinal end joined to the other end of the other vertical frame, and one longitudinal end of the other diagonal brace may be joined to the other end of one of the vertical frames and the other longitudinal end of the other diagonal brace may be joined to one end of the other vertical frame.

[0014] According to the present invention having the feature (3) above, since the braces are joined only to the vertical frames, the rigidity of the corresponding parts is reduced compared to the prior art where the braces are joined to the parts where the vertical frames and the upper frame join, and where the vertical frames and the lower frame join, etc. Therefore, for example, the framework (foundation, beams, columns, etc.) of a wooden building is not affected.

[0015] (4) Furthermore, in the invention described in (1), (2) or (3) above, the external earthquake-resistant reinforcement device of the present invention may be provided with a connecting member that connects the basic frames together, and that can compensate for the difference between the height of the basic frames and the height from the base to the beam if the height of the basic frames when connected together does not reach the height from the base to the beam.

[0016] According to the present invention having the feature described in (4) above, by arranging connecting members between the basic frames, even if the height of the basic frames when connected to each other does not reach the height from the base to the beam, the difference between the height of the basic frame and the height from the base to the beam (the shortfall in the height of the basic frame) can be compensated for.

[0017] (5) The method for constructing an external seismic reinforcement device of the present invention is characterized by comprising the steps of: forming work holes in the wall of a building, which enable the deterioration status of the foundation, beams, and columns to be checked, and which enable reinforcing fittings to be attached to the joints between the foundation and the columns and the joints between the beams and the columns; attaching reinforcing fittings to the joints between the foundation and the columns and the joints between the beams and the columns; and attaching the external seismic reinforcement device described in (1), (2), (3), or (4) above to the wall.

[0018] According to the present invention having the feature (5) above, since work holes are opened in the walls of a building, it is easy to check the deterioration status of the foundation, beams, and columns, and to attach reinforcing metal fittings to the joints between the foundation and columns and the joints between the beams and columns. In addition, since the external seismic reinforcement device according to the invention described in (1), (2), (3), or (4) above is used, installation can be easily performed.

[0019] (6) Furthermore, in the construction method for an external earthquake-resistant reinforcement device of the present invention described in (5) above, after attaching the external earthquake-resistant reinforcement device to the wall, the method may further include the steps of attaching a finishing base material, a waterproof sheet, a finishing material, a drainage device, and side accessories to the external earthquake-resistant reinforcement device in that order, and applying a caulking treatment to the top and sides of the external earthquake-resistant reinforcement device.

[0020] According to the present invention having the above-mentioned feature (6), by sequentially attaching a finishing base material, a waterproof sheet, a finishing material, a water-repellent device, and a side device to the external earthquake-resistant reinforcement device, and further applying a caulking treatment to the top and sides of the external earthquake-resistant reinforcement device, it becomes possible to carry out earthquake-resistant reinforcement work while taking into consideration design and waterproofing. [Effects of the Invention]

[0021] According to the present invention, there is no effect on the framework of the building (foundation, beams, columns, etc.), and it has the effect of improving workability when transporting and installing the basic frame compared to conventional technology.

Note that the arrows in the figures indicate the up-down and left-right directions, respectively (the arrow directions are for illustrative purposes only).

[0025] In Fig. 1, reference numeral 1 denotes a basic frame in a first embodiment of an external seismic reinforcement device according to the present invention. The external seismic reinforcement device in this embodiment is attached and fixed to the outer surface of a wall 104 (see Fig. 8) of a building for the purpose of seismic reinforcement of the building, and includes a plurality of (two in this embodiment) basic frames 1 and a plurality of (two in this embodiment) connecting members 2 that connect the basic frames 1 together. Each component of the external seismic reinforcement device will be described below.

[0026] First, basic frame 1 will be described. As shown in Fig. 1(a), the basic frame 1 comprises a frame body 3 formed in a rectangular shape when viewed from the front, and a pair of diagonal braces 4 arranged so as to intersect each other inside the frame body 3. The frame body 3 has a pair of vertical frames 5, an upper frame 6 connecting one end (upper end in Fig. 1(a)) of each of the vertical frames 5 to each other, and a lower frame 7 connecting the other end (lower end in Fig. 1(a)) of each of the vertical frames 5 to each other.

[0027] As shown in Figure 8, the vertical frame 5 is a portion that extends in the height direction of a column 103 that is joined between a foundation 101 and a beam 102 of a building. As shown in Figure 1(b), a plurality of (five) screw holes 8 are formed through the vertical frame 5. The screw holes 8 are provided at predetermined intervals along the longitudinal direction of the vertical frame 5. The upper frame 6 and the lower frame 7 each have a plurality of (three) screw holes 8 and a plurality of (six) bolt holes 9 formed through them.

[0028] As shown in FIG. 1(a), a mounting portion 10 is formed on the inside of the vertical frame 5, and a mounting portion 11 is formed on the inside of each of the upper frame 6 and lower frame 7. The mounting portions 10, 11 are used to mount the basic frame 1 to a wall 104 of a building (see FIG. 8). As shown in FIG. 1(a), the mounting portions 10, 11 are formed separately from each other (so as not to be continuous with each other). Each of the mounting portions 10, 11 has a plurality (five) of lag screw holes 12 formed therethrough.

[0029] The diagonal brace 4 has a main body 13 that corresponds to approximately the middle of the diagonal brace 4 in the longitudinal direction, and one end 14 and the other end 15 in the longitudinal direction of the diagonal brace 4. As shown in FIG. 1(a), the one end 14 and the other end 15 are formed thinner than the main body 13.

[0030] In Figure 1(a), one of the diagonal braces 4 has one longitudinal end 14 joined to a plate 16 that continues to one end (the upper end in Figure 1(a)) of one of the vertical frames 5 (the vertical frame 5 on the left side of the paper in Figure 1(a)), and the other longitudinal end 15 of the diagonal brace 4 joined to a plate 16 that continues to the other end (the lower end in Figure 1(a)) of the other vertical frame 5 (the vertical frame 5 on the right side of the paper in Figure 1(a)). In addition, one longitudinal end 14 of the other diagonal brace 4 is joined to a plate 16 that continues to the other end (lower end in Figure 1(a)) of one vertical frame 5 (the vertical frame 5 on the left side of the paper in Figure 1(a)), and the other longitudinal end 15 of the diagonal brace 4 is joined to a plate 16 that continues to one end (upper end in Figure 1(a)) of the other vertical frame 5 (the vertical frame 5 on the right side of the paper in Figure 1(a)).

[0031] Next, the connecting member 2 will be described. The connecting member 2 shown in Fig. 2 connects the basic frames 1 together, and is a member that can compensate for the difference between the height of the basic frames 1 and the height from the base 101 to the beam 102 (shortfall in the height of the basic frames 1) when the height of the basic frames 1 when connected together does not reach the height from the base 101 to the beam 102. The connecting member 2 is formed in a box shape with an open front and having an upper wall 17, a lower wall 18, a pair of side walls 19, and a back wall 20. A plurality of (three) bolt holes 21 are formed through each of the upper wall 17 and the lower wall 18.

[0032] Next, a method for installing the external seismic reinforcement device according to this embodiment will be described. First, as shown in Fig. 3, a work hole 105 is opened and formed in a wall 104 of a building. The work hole 105 is formed so that a worker can check the deterioration state of the foundation 101, beams 102, columns 103, etc., and so that reinforcing metal fittings 106 (see Fig. 4) can be attached to the joints between the foundation 101 and columns 103 and the joints between the beams 102 and columns 103. In Fig. 3, reference numeral 100 indicates the foundation of the building. In Fig. 3, the imaginary line indicated by arrow A indicates the installation range of the external seismic reinforcement device according to this embodiment.

[0033] If, as a result of checking the deterioration state of the foundation 101, beams 102, columns 103, etc., it is found that the foundation 101, beams 102, and columns 103 have deteriorated and require reinforcement, as shown in Figure 4, reinforcing metal fittings 106 are attached to the joints between the foundation 101 and columns 103 and between the beams 102 and columns 103. Also, as shown in Figure 4, caulking grooves 107 are formed around the periphery of the installation range of the external seismic reinforcement device on the wall 104 (see the imaginary line indicated by arrow A in Figures 3 and 4).

[0034] The caulking groove 107 is formed with a predetermined width and depth (for example, a width of 8 mm or more and 10 mm or less, and a depth of 10 mm or more and 12 mm or less). The caulking groove 107 formed along the beam 102 (base 101) is formed at a predetermined distance (for example, 30 mm) from the upper end of the installation range of the external seismic reinforcement device (see the imaginary line indicated by arrow A in Figure 5(a)). At the point where the caulking groove 107 formed along the beam 102 illustrated in Figure 5(a) intersects with the caulking groove 107 formed along the column 103, an extension portion 108 is formed by extending the caulking groove 107 by a predetermined length (for example, 30 mm). At the point where the caulking groove 107 formed along the column 103 intersects with the installation range of the external seismic reinforcement device (see the imaginary line indicated by arrow A in FIG. 5(b)), an extension portion 108 is formed by extending the caulking groove 107 by a predetermined length (for example, 30 mm). Note that the above numerical values ​​are merely examples.

[0035] Thereafter, the basic frame 1 is attached to the underside of the installation range of the external seismic reinforcement device (see the imaginary line indicated by arrow A in Figure 6) and fixed in place with lag screws 22. The lag screws 22 are inserted through the lag screw holes 12 (see Figure 1(a)) of the vertical frame 5 and the lower frame 7, and fastened to the base 101 and the column 103.

[0036] After that, the connecting member 2 is attached to the upper frame 6 of the fixed basic frame 1. Specifically, the bolt holes 9 of the upper frame 6 are aligned with the bolt holes 21 of the lower wall 18 of the connecting member 2, and the bolts 28 inserted into the bolt holes 9, 21 are fastened with nuts 29. After that, the basic frame 1 is attached above the installation range of the external seismic reinforcement device (see the imaginary line indicated by arrow A in FIG. 7). As shown in FIG. 8, specifically, the bolt holes 9 of the lower frame 7 are aligned with the bolt holes 21 of the upper wall 17 of the connecting member 2, and the bolts 28 inserted into the bolt holes 9, 21 are fastened with nuts 29. After that, the basic frame 1 is fixed with lag screws 22. The lag screws 22 are inserted into the lag screw holes 12 (see FIG. 1(a)) of the vertical frame 5 and the upper frame 6, and fastened to the beams 102 and columns 103.

[0037] After that, finishing base material 23 (see Figure 9), waterproof sheet 24, and finishing material 25 (see Figure 10) are attached to the basic frame 1 in that order. Furthermore, as shown in Figure 11, a water-repellent attachment 26 is attached to the top end of the external seismic reinforcement device, and side attachments 27 are attached to both sides of the external seismic reinforcement device. After inserting a portion of each of water-repellent attachment 26 and side attachments 27 into caulking grooves 107, they are fixed in place with screws. After that, the areas where caulking grooves 107 are formed and the heads of the screws are caulked. This completes the installation of the external seismic reinforcement device.

[0038] In the external seismic reinforcement device according to the present embodiment described above, the diagonal braces 4 are formed so that their longitudinal ends 14 and 15 are thinner than the longitudinal main body portions 13, resulting in lower rigidity than the diagonal braces of the prior art. This prevents the diagonal braces 4 from affecting the framework (such as the foundation 101, beams 102, and columns 103) of a wooden building, for example. Furthermore, in the external seismic reinforcement device according to the present embodiment, the diagonal braces 4 are formed so that their longitudinal ends 14 and 15 are thinner than the longitudinal main body portions 13, resulting in a smaller size than the diagonal braces of the prior art. This allows the basic frame 1 to be lighter than the prior art.

[0039] Furthermore, with the external seismic reinforcement device according to this embodiment, the mounting portions 10, 11 of the vertical frame 5, the upper frame 6, and the lower frame 7 are formed separately from each other, which reduces the rigidity of these portions compared to the configuration in which the mounting portions 10, 11 are continuous, as in the prior art. This prevents any effect on the framework (such as the foundation 101, beams 102, and columns 103) of a wooden building, for example. Furthermore, with the external seismic reinforcement device according to this embodiment, the mounting portions 10, 11 are formed separately from each other, as described above, which allows the basic frame 1 to be made lighter than the configuration in which the mounting portions are continuous, as in the prior art.

[0040] Furthermore, with the external seismic reinforcement device according to this embodiment, the braces 4 are joined only to the vertical frames 5, and therefore the rigidity of these portions is smaller than in the prior art, where the braces are joined to the points where the vertical frames 5 and the upper frame 6 are connected, and to the points where the vertical frames 5 and the lower frame 7 are connected. This means that, for example, the framework (foundation 101, beams 102, columns 103, etc.) of a wooden building is not affected.

[0041] Furthermore, according to the external earthquake-resistant reinforcement device of this embodiment, by placing connecting members 2 between the basic frames 1, even if the height of the basic frames 1 when connected to each other does not reach the height from the base 101 to the beam 102, the difference between the height of the basic frame 1 and the height from the base 101 to the beam 102 (the shortfall in the height of the basic frame 1) can be compensated for.

[0042] Furthermore, according to the construction method of the external seismic reinforcement device according to this embodiment described above, the work holes 105 are opened and formed in the walls 104 of the building, which makes it easy to check the deterioration status of the foundation 101, beams 102, and columns 103, and to attach the reinforcing metal fittings 106 to the joints between the foundation 101 and columns 103 and the joints between the beams 102 and columns 103. Furthermore, the use of the external seismic reinforcement device according to this embodiment makes installation easy.

[0043] Furthermore, according to the construction method of the external earthquake-resistant reinforcement device of this embodiment described above, the finishing base material 23, waterproof sheet 24, finishing material 25, water-repellent element 26 and side element 27 are sequentially attached to the external earthquake-resistant reinforcement device, and further, by applying caulking to the top and sides of the external earthquake-resistant reinforcement device, construction related to earthquake-resistant reinforcement can be carried out while taking into consideration design and waterproofing.

[0044] Next, the effects of this embodiment will be described. As explained above with reference to Figures 1 to 11, this embodiment has the advantage of not affecting the framework of the building (foundation 101, beams 102, columns 103, etc.), and also improving workability when transporting and installing the basic frame 1 compared to conventional technology. <Embodiment 2>

[0045] The external seismic reinforcement device according to the present invention may use the following embodiment 2 in addition to embodiment 1. Hereinafter, embodiment 2 will be described with reference to Figs. Fig. 12 is a perspective view showing a second embodiment of an external seismic reinforcement device according to the present invention, and Fig. 13 is a perspective view showing a connecting member in Fig. 12. Note that the same components as those in the first embodiment are given the same reference numerals and detailed explanations will be omitted.

[0046] 12 and 13, reference numeral 32 denotes a connecting member in embodiment 2 of the external seismic reinforcement device according to the present invention. The connecting member 32 in this embodiment has the same configuration as the connecting member 2 in embodiment 1 (see FIG. 2), except that its height is higher than that of the connecting member 2 in embodiment 1. The connecting member 32 is used, for example, in cases where the difference between the height of the basic frame 1 and the height from the base 101 to the beam 102 (shortfall in the height of the basic frame 1) cannot be compensated for by the connecting member 2 in embodiment 1.

[0047] Next, the effects of this embodiment will be described. As described above with reference to FIGS. 12 and 13, this embodiment provides the same effects as the first embodiment. <Embodiment 3>

[0048] The external seismic reinforcement device according to the present invention may use the following embodiment 3 in addition to embodiment 1 and embodiment 2. Hereinafter, embodiment 3 will be described with reference to FIG. 14 is a perspective view showing a third embodiment of an external seismic reinforcement device according to the present invention. The same components as those in the first embodiment are given the same reference numerals and detailed descriptions thereof will be omitted.

[0049] 14, the external seismic reinforcement device according to the present invention may be configured to directly connect the basic frames 1 to each other without using the connecting member 2 in embodiment 1 or the connecting member 32 in embodiment 2. This embodiment is used, for example, when there is no height shortfall between the height of the basic frame 1 and the height from the base 101 to the beam 102.

[0050] Next, the effects of this embodiment will be described. As described above with reference to FIG. 14, according to this embodiment, the same effects as those of the first embodiment can be achieved.

[0051] In addition, it goes without saying that the present invention can be modified in various ways without departing from the spirit and scope of the present invention. [Explanation of symbols]
