Abstract
Description
[Technical Field]
[0001] This invention relates to a building reinforcement device, and more particularly to a shear wall device installed in a building. [Previous Technology]
[0002] In recent years, Taiwan has been facing the problem of aging housing. Furthermore, Taiwan is located in an earthquake zone, and older buildings inevitably face concerns about damage and collapse due to earthquakes, leading to safety issues. Constructing new buildings is time-consuming, labor-intensive, and increases carbon emissions; therefore, reinforcing existing buildings to extend their lifespan is an inevitable trend. Adding shear walls to buildings is a common construction method that can improve the structural rigidity of the building.
[0003] Currently known shear wall devices are typically constructed of reinforced concrete (RC). Reinforced concrete construction requires the extensive embedding of reinforcing bars before using concrete as the main structural element of the wall. Reinforced concrete shear walls require wet construction methods, resulting in high labor and time costs. Furthermore, concrete is a high-carbon-emission, difficult-to-recycle, and environmentally unfriendly material. Moreover, the high self-weight of concrete walls can negatively impact the structural strength of buildings. Therefore, there is still room for improvement in currently known shear wall systems. [Summary of the Invention]
[0004] Therefore, the object of the present invention is to provide a shear wall device that can overcome at least one disadvantage of the prior art.
[0005] Therefore, the shear wall device of the present invention is suitable for fixing to a building and includes a steel frame unit, a side plate unit, and a first positioning unit.
[0006] The steel frame unit includes a bottom beam and a top beam fixed to the building, and a plurality of vertically extending and horizontally spaced columns arranged between the bottom beam and the top beam. The side panel unit includes at least one plate disposed on the steel frame unit. The at least one plate is at least 30 mm thick and is made of wood. The first positioning unit is used to fix the side panel unit to the steel frame unit and includes a plurality of first positioning members fixedly inserted through the side panel unit and the steel frame unit.
[0007] The advantages of this invention are: by combining the steel frame unit and the side plate unit with steel and wood, the complementary characteristics are achieved. Wood can prevent the local buckling problem of steel, and steel can solve the problems of complex construction and stress concentration at the joint of wood. Compared with known reinforced concrete shear wall devices, it has the advantages of being lightweight, recyclable and easy to construct.
Implementation Method
[0008] Before the present invention is described in detail, it should be noted that similar elements are represented by the same numbers in the following description.
[0009] Referring to Figures 1, 2 and 3, a first embodiment of the shear wall device of the present invention is applicable to a building 1 and includes a steel frame unit 2 for fixing to the building 1, a side plate unit 3 disposed on the steel frame unit 2, and a first positioning unit 4 disposed on the side plate unit 3 and the steel frame unit 2.
[0010] The steel frame unit 2 includes a bottom beam 21 and a top beam 22, which are vertically parallel and spaced apart and suitable for fixing to the building 1; several vertically extending and horizontally spaced column assemblies 23, which are arranged between the bottom beam 21 and the top beam 22; and several steel frame positioning members 24 for fixing the column assemblies 23 to the bottom beam 21 and the top beam 22. The bottom beam 21 and the top beam 22 are U-shaped steels with openings facing each other. The steel frame positioning members 24 pass through the bottom beam 21 and the column assemblies 23, or the top beam 22 and the column assemblies 23.
[0011] In this embodiment, each column group 23 (as shown in Figure 2) has two columns 231 fixed at their upper and lower ends to the top beam 22 and the bottom beam 21 respectively, and the columns 231 of each column group 23 are C-shaped steels with opposite openings and arranged in a front-to-back manner. In other embodiments, each column group 23 may also have only one column 231, that is, a C-shaped steel is provided on the side adjacent to the side plate unit 3.
[0012] The side panel unit 3 includes several vertically extending and horizontally abutting plates 31 arranged on the steel frame unit 2. Each plate 31 has its left and right sides respectively disposed on two adjacent column groups 23. These plates 31 are made of engineered wood with a thickness of at least 30 mm, sufficient to achieve reinforced support and fire resistance. In this embodiment, the side panel unit 3 is disposed on the same side of the steel frame unit 2, but in other embodiments, the side panel unit 3 can also be disposed on two opposite sides of the steel frame unit 2 to increase strength and aesthetics. In this embodiment, the thickness of these plates 31 is preferably 50 mm of engineered Japanese cedar. A greater thickness of these plates 31 provides better support, but also increases the required space and cost; therefore, plates 31 of appropriate thickness can be selected according to actual needs.
[0013] The first positioning unit 4 includes several first positioning members 41 fixedly inserted through the side plate unit 3 and the steel frame unit 2, and used to fix the side plate unit 3 to the steel frame unit 2. Each of the first positioning members 41 may be inserted through one of the plates 31 and one of the columns 231, the top beam 22 or the bottom beam 21. The first positioning members 41 may be, but are not limited to, self-drilling screws.
[0014] Referring to Figures 1, 3, and 4, during installation, an installation location can be selected in the building 1. This location can be between structural beams and columns of the building 1, or on a wall; the implementation is not limited to this. The bottom beam 21 and the top beam 22 are then fixed to the building 1. The bottom beam 21 and the top beam 22 can be fixed to the building 1 using, but is not limited to, expansion bolts or chemical anchors. Next, the columns 231 are grouped in pairs to form column groups 23. These column groups 23 are then arranged at intervals between the bottom beam 21 and the top beam 22, and the column groups 23 are fixed to the bottom beam 21 and the top beam 22 using steel frame positioning members 24. In this embodiment, the steel frame positioning members 24 are screws and have a protrusion 241.
[0015] Next, four grooves 312 are drilled at the four corner positions 311 of each plate 31. Each groove 312 can accommodate the protrusion 241 at the corresponding position when the plate 31 is installed to the steel frame unit 2. Finally, the plates 31 are fixed to the bottom beam 21, the top beam 22, and the column assembly 23 around their perimeter using the first positioning members 41 to complete the installation of the shear wall device of the present invention.
[0016] After installation, painting or coating can be done as needed, but no further treatment is required, as the panels 31 themselves have a beautiful and durable appearance, which can save costs and reduce carbon emissions.
[0017] In this embodiment, the left and right width of the plate 31 is 50 cm. Therefore, when setting the column group 23, the width of the plate 31 can be matched so that the left and right sides of each plate 31 can be fixed. The length of the plate 31 and the column 231 can be pre-cut to the same height as the installation position to facilitate direct installation on site.
[0018] Referring to Figures 5 and 6, another embodiment of the first embodiment differs in that the shear wall device further includes a second positioning unit 5 disposed between the side plate unit 3 and the steel frame unit 2. The second positioning unit 5 includes several second positioning members 51 disposed in each of the column groups 23. These second positioning members 51 are used to fix the side plate unit 3 to the steel frame unit 2. These second positioning members 51 are adhesive, which can strengthen the connection between the side plate unit 3 and the steel frame unit 2.
[0019] Referring to Figure 7, a second embodiment of the shear wall device of the present invention differs from the first embodiment in that: the side plate unit 3 includes only one plate 31, which can completely cover the steel frame unit 2.
[0020] In summary, the shear wall device of the present invention utilizes the complementary characteristics of the steel frame unit 2 and the side plate unit 3 through the combination of steel and wood. The wood can prevent the local buckling problem of steel, and the steel can solve the problems of complex construction and stress concentration at the joint of wood. Compared with the known reinforced concrete shear wall devices, it has the advantages of being lightweight, recyclable and easy to construct, and thus can indeed achieve the purpose of the present invention.
