Abstract
Description
Technical Field
[0001] The present disclosure relates to a fixing bar for a shear wall, a shear wall comprising the fixing bar, and a construction method thereof. Background Art
[0002] The process of making a shear wall includes providing two steel meshes, each consisting of a plurality of vertical steel bars and transverse steel bars, setting the two steel meshes at a distance from each other, connecting and fixing the two steel meshes with a plurality of fixing bars, and then pouring concrete to cover the two steel meshes.
[0003] Conventional anchor bars are long, straight steel bars with hooks at each end, which are fixed to the vertical bars of two meshes. Using this type of anchor bar structure to secure two opposing meshes requires a large number of bars to stably connect and secure the two meshes. For example, in a non-confined area without stirrups, anchor bars must be placed transversely at intervals four times the spacing between two adjacent vertical bars in the meshes. This results in a long construction time and consumes a large amount of steel material. Summary of the Invention
[0004] To solve the above problems, an embodiment of the present disclosure provides a fixing bar for a shear wall, wherein the shear wall includes a first steel mesh and a second steel mesh, wherein the first steel mesh and the second steel mesh are arranged relative to each other and spaced apart by a predetermined distance, and the fixing bar includes a first end, a second end, and two connecting portions; the first end is configured to surround and be fixed to two adjacent upright steel bars of the first steel mesh, the second end has two free ends, and the two free ends are configured to be respectively fixed to two adjacent upright steel bars of the second steel mesh; the two connecting portions respectively connect the first end and the second end.
[0005] Another embodiment of the present disclosure provides a method for fabricating a building structure, comprising: providing two precast columns spaced apart by a third predetermined distance, the two precast columns each including a plurality of tie rods extending toward each other; providing a first reinforcement mesh and a second reinforcement mesh between the two precast columns, the first reinforcement mesh and the second reinforcement mesh being disposed opposite each other and spaced apart by a predetermined distance; connecting outer sides of the first reinforcement mesh and the second reinforcement mesh to the plurality of tie rods of the two precast columns; and providing a plurality of fixing bars to fix the first reinforcement mesh and the second reinforcement mesh to each other. Each of the fixing bars is configured to simultaneously surround and connect two adjacent vertical bars of the first reinforcement mesh and two adjacent vertical bars of the second reinforcement mesh.

[0031] The following disclosure provides many different embodiments or examples for implementing the different features of the provided theme. The specific examples of the elements and arrangements will be described below to simplify this disclosure. Of course, these are merely examples and are not intended to be limiting. For example, in the following description, "a first component is formed above or on a second component" may include embodiments in which the first component and the second component are directly contacted, and may also include embodiments in which additional components may be formed between the first component and the second component so that the first component and the second component may not be directly contacted. In addition, this disclosure may repeat element symbols and / or letters in various examples. This repetition is intended to simplify and clarify and does not itself indicate the relationship between the various embodiments and / or configurations discussed.
[0032] Furthermore, for convenience of description, spatially relative terms (e.g., "below," "beneath," "below," "above," "upper," and the like) may be used herein to describe the relationship of one element or component to another element or component, as illustrated in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. The device may be otherwise oriented (rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein may be interpreted accordingly.
[0033] As used herein, terms such as "first," "second," and "third" describe various elements, components, regions, layers, and / or sections, and these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or section from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and "third" as used herein do not imply a sequence or order.
[0034] As used herein, the terms "substantially," "approximately," "substantially," and "about" are used to describe and explain small variations. When used in conjunction with an event or condition, the terms may relate to instances in which the event or condition occurred precisely as well as instances in which the event or condition occurred very approximately. For example, when used in conjunction with a numerical value, the terms may relate to a range of variation of less than or equal to ±10% of the numerical value, such as less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. For example, if the difference between two numerical values is less than or equal to ±10% of the average of the values (e.g., less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%), then the values may be considered to be "substantially" the same or equal. For example, "substantially" parallel can involve an angular variation of less than or equal to ±10° relative to 0°, such as less than or equal to ±5°, less than or equal to ±4°, less than or equal to ±3°, less than or equal to ±2°, less than or equal to ±1°, less than or equal to ±0.5°, less than or equal to ±0.1°, or less than or equal to ±0.05°. For example, "substantially" perpendicular can involve an angular variation of less than or equal to ±10° relative to 90°, such as less than or equal to ±5°, less than or equal to ±4°, less than or equal to ±3°, less than or equal to ±2°, less than or equal to ±1°, less than or equal to ±0.5°, less than or equal to ±0.1°, or less than or equal to ±0.05°.

Figure 1 As shown, the fixing rib 1 of the present disclosure comprises a first end 11, a second end 12, and two connecting portions 13 connecting the first and second ends 11 and 12, respectively. The first end 11, the second end 12, and the connecting portions 13 are integrally formed. The first end 11 is generally in an inverted U-shape and has two bent sections 111 on either side. The second end 12 has two free ends, each of which has a hook 121. In some embodiments of the present disclosure, the distance between the two bent sections 111 of the first end 11 is approximately equal to the distance between the two hooks 121 of the second end 12. In the above-described embodiments of the present disclosure, one end of each connecting portion 13 is connected to the bent section 111 of the first end 11, and the other end is connected to the hook 121 of the second end 12. The distance between the two connecting portions 13 gradually decreases as it moves from the first end 11 toward the second end 12, and the two hooks of the second end 12 are bent toward each other and toward the outside of the fixing rib 1.
[0036] See also Figures 2A to 2K , which are a series of schematic diagrams of a construction method for manufacturing shear walls 100, 100' using the fixing bars 1 according to the embodiment of the present disclosure.
[0037] like Figure 2A In the embodiment shown, the present construction method provides a plurality of precast columns 31, 32, 33 on the building base. The precast columns 31, 32, 33 are spaced apart by a predetermined distance.

A plurality of vertical steel bars 37 are provided on the building base between the precast columns 31, 32, 33 to connect and secure the bottom sides of the steel meshes 10 and 20 (see FIG. 1 ). Figure 2C and Figure 2D ).

The extension bars 311, 321, and 331 may be threaded bars or ordinary bars with one end threaded.
[0039] like Figure 2CAs shown, steel meshes 10 and 20 are disposed between precast columns 31 and 32, with mesh 10 and mesh 20 spaced a predetermined distance apart. Mesh 10 has two sides connected to the extended bars 311 and 321 of precast column 31 and 32, respectively, while mesh 20 has two sides connected to the other set of extended bars 311 and 321 of precast column 31 and 32, respectively. Furthermore, meshes 10' and 20' are disposed between precast columns 32 and 33, with mesh 10' and mesh 20' spaced a predetermined distance apart. Mesh 10' has two sides connected to the extended bars 321 and 331 of precast column 32 and 33, respectively, while mesh 20' has two sides connected to the other set of extended bars 321 and 331 of precast column 32 and 33, respectively.
[0040] like Figure 2D As shown, the construction method of this embodiment combines one or more Figure 1 The fixing rib 1 shown is disposed between the steel meshes 10 and 20, and the steel meshes 10 and 20 are connected and fixed to each other via the fixing rib 1. Figure 1 The fixing ribs 1 shown are disposed between the steel meshes 10 ′ and 20 ′, and the steel meshes 10 ′ and 20 ′ are connected and fixed to each other via the fixing ribs 1 .
[0041] Figure 2E It is from Figure 2D The schematic diagram of the X1 direction is shown in FIG. Figure 2E As shown, a steel mesh 10 and a steel mesh 20 face each other and are spaced a predetermined distance H apart. The steel mesh 10 has a plurality of spaced vertical steel bars 101, with a distance s1 between adjacent vertical steel bars 101. The steel mesh 20 has a plurality of spaced vertical steel bars 201, with a distance s2 between adjacent vertical steel bars 201. In some embodiments of the present disclosure, s1 is substantially equal to s2.
[0042] Re-attend Figure 2E , several such as Figure 1The fixed bars 1 shown are arranged in an array and connect the steel mesh 10 and the steel mesh 20; the fixed bars 1 are connected to two adjacent upright bars 101 of the steel mesh 10 and two adjacent upright bars 201 of the steel mesh 20, so as to connect the steel mesh 10 and the steel mesh 20. The first end 11 of the fixed bar 1, which is roughly in the shape of an inverted U, is configured to surround the outer edges of the two adjacent upright bars 101 of the steel mesh 10, and the two bent sections 111 of the first end 11 respectively roughly surround or hook the two adjacent upright bars 101 of the steel mesh 10. In addition, the two hooks 121 of the second end 12 of the fixed bar 1 respectively roughly surround or hook the two adjacent upright bars 201 of the steel mesh 20, and the two connecting portions 13 of the fixed bar 1 extend from the outside of the two adjacent upright bars 101 of the first steel mesh 10 to the inside of the two adjacent upright bars 201 of the second steel mesh 20. As shown Figure 2D As shown, the extending direction of the connection portion 13 of the fixing bar 1 and the extending direction of the steel mesh 10 and / or the steel mesh 20 form a non-right angle with each other.
[0043] like Figure 2E As shown, in this embodiment, two adjacent fixing bars 1 are arranged in the same direction and connect the steel meshes 10 and 20 in the same manner. For example, both are connected to two adjacent upright steel bars 101 of the steel mesh 10 with their first ends 11, and are connected to two adjacent upright steel bars 201 of the steel mesh 20 with their second ends 12.
[0044] In addition, adjacent fixing bars 1 are arranged at a distance D1 from each other; in some embodiments of the present disclosure, the distance between two adjacent fixing bars 1 is approximately equal to eight times the distance between two adjacent upright steel bars 101 of the steel mesh 10 or approximately equal to eight times the distance between two adjacent upright steel bars 201 of the steel mesh 20, that is, D1 is approximately equal to 8 times s1 or approximately equal to 8 times s2.
[0045] Furthermore, the plurality of fixing ribs 1 are as follows Figure 2E The horizontal arrangement shown can also be arranged along the extension direction of the vertical steel bars 101 of the first steel mesh 10 and the vertical steel bars 201 of the second steel mesh 20 (not shown). In some embodiments of the present disclosure, Figure 2E The fixed bar 1 shown in FIG. 1 may be provided with another identical or similar fixed bar at another predetermined distance below the vertical bars 101 of the first reinforcement mesh 10 and the vertical bars 201 of the second reinforcement mesh 20 in the extending direction. Figure 1In the illustrated embodiment, the fixing bar 1 (not shown) has a substantially inverted U-shaped first end portion disposed so as to surround two adjacent upright bars 101 of the reinforcement mesh 10, while the two hooks at the second end portion of the fixing bar 1 (not shown) respectively surround or hook two adjacent upright bars 201 of the reinforcement mesh 20. In other words, the fixing bars disposed above and below each other are disposed in the same direction and connect the reinforcement meshes 10 and 20 in the same manner.
[0046] like Figure 2F As shown, precast beam 301 is positioned above steel meshes 10 and 20 and extends between the tops of precast columns 31 and 32. Below precast beam 301, rebar 3011 is provided for connection to rebar meshes 10 and 20, and a 5-centimeter gap is maintained between the bottom surface of precast beam 301 and rebar meshes 10 and 20 (not shown). Furthermore, precast beam 302 is positioned above rebar meshes 10' and 20' and extends between the tops of precast columns 32 and 33. Below precast beam 302, rebar 3021 is provided for connection to rebar meshes 10' and 20', and a 5-centimeter gap is maintained between the bottom surface of precast beam 302 and rebar meshes 10' and 20' (not shown). In some embodiments of the present disclosure, precast beams 301 and 302 may be precast beams or semi-precast beams.
[0047] like Figure 2G 、 2H As shown, the construction method of this embodiment provides templates 41, 42, 41', and 42'; the templates 41 and 42 are configured to accommodate the steel meshes 10 and 20 therein, in other words, the steel meshes 10 and 20 are located between the templates 41 and 42; the templates 41' and 42' are configured to accommodate the steel meshes 10' and 20' therein, in other words, the steel meshes 10' and 20' are located between the templates 41' and 42'.
[0048] Figure 2I It is from Figure 2H Schematic diagram of observation in the X2 direction as shown. Figure 2H As shown, the steel meshes 10 and 20 extend between the precast columns 31 and 32 respectively, and their two sides are connected to the extended steel bars 311 of the precast column 31 and the extended steel bars 321 of the precast column 32 respectively; Figure 2D The steel meshes 10 and 20 are connected in the manner described. Figure 2I As shown, the templates 41 and 42 are configured to accommodate the steel meshes 10 and 20 between the templates 41 and 42. Furthermore, a plurality of pull tabs 45 are provided to connect the templates 41 and 42. The connecting pull tabs 45 are configured to pass through the templates 41 and 42 and have their two ends fixed to the templates 41 and 42, thereby tightening the templates 41 and 42.
[0049] like Figure 2J As shown, the template 41 has grouting holes 411 and 413 near the top and the template 42 has grouting holes 421 and grouting holes 423 near the top. Concrete 50 is poured between the templates 41 and 42 and between the templates 41' and 42' (not shown); Figure 2J As shown in the example, concrete 50 is injected between formworks 41 and 42 through grouting holes 421 in formwork 42. When concrete 50 reaches near the tops of formworks 41 and 42, air and a small amount of excess concrete 50 are discharged through the grouting holes 411, 413, and 423. When a small amount of concrete 50 is discharged from the grouting holes 411, 413, and 423, the air has been removed and the concrete pouring operation can be stopped. Furthermore, after the concrete 50 reaches an initial set state, micro-expansion mortar (not shown) can be poured within a spacing of approximately 5 cm between the bottom of precast beam 301 and the steel meshes 10 and 20, and between the bottom of precast beam 302 and the steel meshes 10' and 20'. Figure 2K The shear wall 100 and the shear wall 100 ′ are shown after the concrete 50 is solidified and the formwork 41 , 42 and the formwork 41 ′, 42 ′ are removed.
[0050] See Figures 3A to 3J , which are a series of schematic diagrams of a construction method for manufacturing shear walls 200, 200' using the fixing bars 1 according to the embodiment of the present disclosure.
[0051] like Figure 3A In the embodiment shown, the present construction method provides a plurality of precast columns 34, 35, 36 on the building base. The precast columns 34, 35, 36 are spaced apart by a predetermined distance. In some embodiments of the present disclosure, the distance between the precast columns 34 and 35 is greater than, equal to, or less than the distance between the precast columns 35 and 36. A plurality of vertical steel bars 38 are provided on the building base between the precast columns 34, 35, 36 to connect and secure the bottom sides of the steel meshes 10 and 20 (see FIG. Figure 3C and Figure 3D ).
[0052] See also Figure 3B Each of the precast columns 34, 36, 36 is provided with a plurality of tie rods 39' along its height and width directions. Nut heads 391' are provided on both sides of each tie rod 39 for connecting the steel bars. A plurality of extension steel bars 341 are connected to the nut heads of the corresponding tie rods 39' as extensions to connect to both sides of the steel mesh 60 and the steel mesh 70 (see FIG. Figure 3C and Figure 3DIn certain embodiments of the present disclosure, at least one of the plurality of extension bars 341 on both sides of precast column 34 extends generally toward precast column 35, at least one of the plurality of extension bars 351 on both sides of precast column 35 extends generally toward precast column 34, at least one of the plurality of extension bars 351 on both sides of precast column 35 extends generally toward precast column 36, and at least one of the plurality of extension bars 361 on both sides of precast column 36 extends generally toward precast column 35. Extension bars 341, 351, and 361 may be threaded bars or ordinary bars with one end threaded.
[0053] like Figure 3C As shown, steel meshes 60 and 70 are disposed between precast columns 34 and 35, with steel mesh 60 and steel mesh 70 spaced a predetermined distance apart. Steel mesh 60 has two sides connected to the extended steel bars 341 of precast column 34 and the extended steel bars 351 of precast column 35, respectively. Steel mesh 70 has two sides connected to the other set of extended steel bars 341 of precast column 34 and the other set of extended steel bars 351 of precast column 35, respectively. Furthermore, steel meshes 60' and 70' are disposed between precast columns 35 and 36, with steel mesh 60' and steel mesh 70' spaced a predetermined distance apart. Steel mesh 60' has two sides connected to the extended steel bars 351 of precast column 35 and the extended steel bars 361 of precast column 36, respectively. Steel mesh 70' has two sides connected to the other set of extended steel bars 351 of precast column 35 and the other set of extended steel bars 361 of precast column 36, respectively.
[0054] like Figure 3D As shown, one or more Figure 1 The fixing bar 1 shown is arranged between the steel meshes 60 and 70 and connects the steel meshes 60 and 70. Figure 1 The fixing bar 1 shown is disposed between the steel meshes 60 ′ and 70 ′ and connects the steel meshes 60 ′ and 70 ′.
[0055] Figure 3E It is from Figure 3D Schematic diagram of observation in the Y1 direction as shown. Figure 3D As shown, steel mesh 60 and steel mesh 70 face each other and are spaced apart. Steel mesh 60 has a plurality of spaced-apart vertical steel bars 601, with a distance s3 between adjacent vertical steel bars 601. Steel mesh 70 has a plurality of spaced-apart vertical steel bars 701, with a distance s4 between adjacent vertical steel bars 701. In some embodiments of the present disclosure, s3 is substantially equal to s4.
[0056] Re-attend Figure 3E , several such as Figure 1 The fixed bars 1 shown are arranged and arranged to connect the steel mesh 60 and the steel mesh 70; Figure 1 The fixed bars 1 on the left and right sides shown are used to connect two adjacent upright bars 601 of the steel mesh 60 and two adjacent upright bars 701 of the steel mesh 70, thereby connecting the steel mesh 60 and the steel mesh 70. The first end portion 11 of the fixed bar 1, which is roughly in the shape of an inverted U, is configured to surround the outer edges of the two adjacent upright bars 601 of the steel mesh 60, and the two bent sections 611 of the first end portion 11 respectively roughly surround or hook the two adjacent upright bars 601 of the steel mesh 60. In addition, the two hooks 121 of the second end portion 12 of the fixed bar 1 respectively roughly surround or hook the two adjacent upright bars 701 of the steel mesh 70. In this way, the two connecting portions 13 of the fixed bar 1 extend from the outer sides of the two adjacent upright bars 601 of the first steel mesh 60 to the inner sides of the two adjacent upright bars 701 of the second steel mesh 70. Furthermore, as Figure 3E As shown, the extending direction of the connection portion 13 of the fixing bar 1 and the extending direction of the steel mesh 60 and / or the steel mesh 70 are at a non-right angle to each other.
[0057] like Figure 3E As shown, the central fixing rib 1 of the adjacent left and right fixing ribs 1 also connects two adjacent upright steel bars 601 of the steel mesh 60 and two adjacent upright steel bars 701 of the steel mesh 70, but they are arranged in opposite directions; the central fixing rib 1 surrounds the outer edges of the two adjacent upright steel bars 701 of the steel mesh 70 with a first end portion 11 that is roughly U-shaped, and the two bent sections 111 of the first end portion 11 roughly surround or hook the two adjacent upright steel bars 701 of the steel mesh 70, and the two hooks 121 of the second end portion 12 roughly surround or hook the two adjacent upright steel bars 601 of the steel mesh 60. In this way, the two connecting portions 13 of the fixing rib 1 extend from the outside of the two adjacent upright steel bars 701 of the second steel mesh 70 to the inside of the two adjacent upright steel bars 601 of the first steel mesh 60, respectively. In addition, as Figure 3E As shown, the extending direction of the connecting portion 13 of the fixing bar 1 is at a non-perpendicular angle to the extending direction of the reinforcement mesh 60 or the reinforcement mesh 70. In other words, two adjacent fixing bars 1 are connected to the reinforcement meshes 60 and 70 in different orientations. For example, if a fixing bar 1 is connected to two adjacent upright bars 601 of the reinforcement mesh 60 at its first end 11 and to two adjacent upright bars 701 of the reinforcement mesh 70 at its second end 12, then the adjacent fixing bar 1 is connected to two adjacent upright bars 701 of the reinforcement mesh 70 at its first end 11 and to two adjacent upright bars 601 of the reinforcement mesh 60 at its second end 12.
