Description
Technical Field
[0001] This disclosure relates to the field of column reinforcement positioning technology, and in particular to a reusable column reinforcement anti-displacement device. Background Technology
[0002] Most independent foundations lack top reinforcement, making it difficult to secure the column reinforcement during foundation construction. Currently, the common method is to use steel pipes or rebars as diagonal braces, with one end supporting the column reinforcement and the other end supporting the bottom reinforcement of the foundation. However, this existing technology has the following drawbacks: 1. Poor forming quality: The diagonal bracing steel pipes or rebars are tied with wire, which is easily damaged during foundation concrete pouring, causing the bracing steel pipes or rebars to fail and leading to column reinforcement misalignment. 2. Inability to be reused: Since one end of the diagonal bracing steel pipe or rebar is supported on the bottom reinforcement of the foundation, the lower half of the pipe or rebar is embedded in the concrete during foundation concrete pouring, requiring subsequent cutting and making it unusable. 3. Increased labor costs: The diagonal bracing steel pipes or rebars need to be cut manually, and column reinforcement misalignment also requires handling, increasing labor costs. Therefore, it is necessary to optimize and improve existing column reinforcement anti-misalignment fixing devices to address the aforementioned shortcomings of the existing technology. Utility Model Content
[0003] To overcome the shortcomings of existing technology, this utility model proposes a reusable column reinforcement anti-displacement device, which can achieve anti-displacement fixing of column reinforcement and can be reused.
[0004] The specific technical solution of this utility model is a reusable anti-displacement device for column reinforcement, comprising multiple fixing components and multiple adjustable diagonal braces. The fixing components are strip steel plates with multiple elongated slots along their extension direction. The multiple fixing components are fixed by bolts and first nuts passing through the elongated slots and connected to form a closed fixing frame. The fixing frame is tightly surrounded around the tied column reinforcement. Each of the four sides of the fixing frame is provided with an adjustable diagonal brace. The upper end of the adjustable diagonal brace is connected to the fixing component, and the lower end of the adjustable diagonal brace is connected to a positioning connector pre-set around the tied column reinforcement. By adjusting the tension or loosening of the adjustable diagonal braces connected around the fixing frame, the verticality of the column reinforcement can be adjusted.
[0005] As a preferred embodiment, the adjustable diagonal brace includes a hollow straight tube, a first connecting rod and a second connecting rod sleeved at both ends of the hollow straight tube. The first connecting rod and the second connecting rod are telescopically adjustable with the hollow straight tube. The front ends of the first connecting rod and the second connecting rod are bent in the opposite direction to the hollow straight tube, so that when the first connecting rod is connected to the fixing member and the second connecting rod is connected to the positioning connecting member, the hollow straight tube is diagonally supported.
[0006] Furthermore, the outer walls of the first connecting rod and the second connecting rod between the rear end and the front end bend are respectively provided with a first external thread and a second external thread. The first external thread and the second external thread have opposite thread directions. The hollow straight tube is provided with a second nut that is connected to the first external thread and the second thread respectively. When the hollow straight tube is rotated clockwise in the circumferential direction, the first connecting rod and the second connecting rod are rotated into the hollow straight tube in opposite directions to achieve tightening. When the hollow straight tube is rotated counterclockwise in the circumferential direction, the first connecting rod and the second connecting rod are rotated out of the hollow straight tube in opposite directions to achieve loosening.
[0007] Furthermore, the positioning connector consists of four supporting steel bars arranged in the east-west-north-south directions around the corresponding tied column reinforcement. The lower ends of the four supporting steel bars are fixedly welded to the bottom reinforcement of the independent foundation, and the upper ends of the four supporting steel bars face upwards.
[0008] Preferably, the positioning connector consists of four supporting steel bars arranged in the east-west-north-south directions around the corresponding tied column reinforcement bars. The lower ends of the four supporting steel bars are fixed to the outer perimeter of the independent foundation, and the upper ends of the four supporting steel bars face upwards.
[0009] Furthermore, both the first connecting rod and the second connecting rod have through holes at their front ends, extending through the top and bottom. The first connecting rod is connected to the elongated slot of the fixing member through the through hole and is fixed by bolts and a first nut. The through hole of the second connecting rod is connected to the positioning connecting member.
[0010] Furthermore, a screw handle is welded to the middle of the outer wall of the hollow straight tube. The screw handle consists of two U-shaped steel bars symmetrically welded to the outer wall of the hollow straight tube, which is used to circumferentially screw the hollow straight tube.
[0011] The beneficial effects of this utility model are as follows: The anti-displacement device for column reinforcement in independent foundations designed in this scheme uses multiple fixing components that can be spliced together through long slots to form a fixed frame of different closed diameters, used to securely surround the tied column reinforcement. An adjustable diagonal brace is connected to each of the four sides of the fixed frame formed by the fixing components. The lower end of the adjustable diagonal brace is connected to a positioning connector pre-installed around the tied column reinforcement. By adjusting the tension or loosening of the adjustable diagonal braces connected around the fixed frame, the verticality of the column reinforcement can be adjusted until the verticality and positioning dimensions are within the allowable error range, thereby achieving the purpose of preventing displacement and fixing the column reinforcement, which helps ensure the forming quality of the column reinforcement in independent foundations. After the concrete pouring of the independent foundation is completed, the fixing components and adjustable diagonal braces can be removed using bolts and a first nut, allowing for reuse of the fixing components and adjustable diagonal braces, saving a significant amount of steel reinforcement material. Furthermore, the assembly and disassembly of this device are simple and require no professional guidance. Attached Figure Description

[0021] Please refer to Figures 1 to 4 This is a specific embodiment of a reusable anti-displacement device for column reinforcement disclosed in this solution. In this embodiment, the anti-displacement device for column reinforcement includes four fixing members 20 and four adjustable diagonal braces 30. The fixing members 20 are strip steel plates with multiple long slots 201 along the extension direction of the strip steel plates. The multiple fixing members 20 are fixed by bolts 01 and first nuts 02 passing through the long slots 201 and are connected to form a closed fixing frame. The fixing frame is tightly surrounded around the tied column reinforcement 10. Each of the four sides of the fixing frame is provided with an adjustable diagonal brace 30. The upper end of the adjustable diagonal brace 30 is connected to the fixing member 20, and the lower end of the adjustable diagonal brace 30 is connected to the positioning connectors preset around the tied column reinforcement 10. By adjusting the tension or loosening of the adjustable diagonal braces 30 connected around the fixing frame, the verticality of the column reinforcement 10 can be adjusted. Specifically, the fastener 20 is made of a steel plate with a thickness of 5-10mm and a width of 100mm. The length is determined according to the size of the column. For example, the cross-sectional size of the square column in this embodiment is at least 200mm larger. The long slot 201 in this embodiment has a size of 150×20mm.
[0022] As a preferred embodiment, the adjustable diagonal brace 30 includes a hollow straight tube 301, a first connecting rod 302 and a second connecting rod 303 sleeved at both ends of the hollow straight tube 301. The first connecting rod 302 and the second connecting rod 303 are telescopically adjustable with the hollow straight tube 301. The front ends of the first connecting rod 302 and the second connecting rod 303 are bent in the opposite direction to the hollow straight tube 301, so that when the first connecting rod 302 is connected to the fixing member 20 and the second connecting rod 303 is connected to the positioning connecting member, the hollow straight tube 301 is diagonally supported.
[0023] Furthermore, the outer walls of the first connecting rod 302 and the second connecting rod 303 between their rear ends and the front bends are respectively provided with a first external thread and a second external thread. The first external thread and the second external thread have opposite thread directions. The hollow straight tube 301 is provided with a second nut 304 that is connected to the first external thread and the second external thread respectively. When the hollow straight tube 301 is rotated clockwise in the circumferential direction, the first connecting rod 302 and the second connecting rod 303 are rotated into the hollow straight tube 301 in opposite directions to achieve tightening. When the hollow straight tube 301 is rotated counterclockwise in the circumferential direction, the first connecting rod 302 and the second connecting rod 303 are rotated out of the hollow straight tube 301 in opposite directions to achieve loosening. Specifically, the hollow straight tube 301 is made of Ф48x3.2mm steel pipe, and two second nuts 304 are provided at each end of the steel pipe. A notch can be cut at the corresponding position of the steel pipe to fit the second nut 304, and then the second nut 304 is fixed in the steel pipe by welding.
[0024] Please refer to Figure 1 , Figure 2 The positioning connector consists of four supporting steel bars 40 arranged in the east-west, north-south directions around the corresponding tied column reinforcement 10. The lower ends of the four supporting steel bars 40 are fixedly welded to the bottom reinforcement of the independent foundation 100, and the upper ends of the four supporting steel bars 40 face upwards. By setting the four supporting steel bars 40 on the base of the independent foundation 100, the supporting steel bars 40 cannot be removed when the fixing component 20 and the adjustable diagonal brace 30 are subsequently dismantled, and the supporting steel bars 40 cannot be reused. However, given the available external space... The lower ends of the four supporting steel bars 40 can be fixed to the outer area of the independent foundation 100, so that the supporting steel bars 40 can be removed and reused when the fixing parts 20 and the adjustable diagonal braces 30 are removed later.
[0025] As a structure in which the first connecting rod 302 and the second connecting rod 303 respectively connect the fixing member 20 and the supporting steel bar 40, the front end of the first connecting rod 302 and the second connecting rod 303 are provided with through holes 305 that penetrate the upper and lower surfaces. The first connecting rod 302 is connected to the long slot hole 201 of the fixing member 20 through the through hole 305 and is fixed by setting bolts 01 and first nuts 02. The through hole 305 of the second connecting rod 303 is sleeved on the supporting steel bar 40.
[0026] Preferably, a screw handle 306 is welded to the middle of the outer wall of the hollow straight tube 301. The screw handle 306 is made of two U-shaped steel bars symmetrically welded to the outer wall of the hollow straight tube 301, and is used to circumferentially screw the hollow straight tube 301.
[0027] In this embodiment, the four fixing members 20 form a rectangular closed fixing frame to tightly frame the outer perimeter of the column reinforcement 10 inside the cast square column of the independent foundation 100. Then, the long slot 201 at the middle position of the four fixing members 20 is locked to the through hole 305 of the first connecting rod 302 of the adjustable diagonal brace 30 by bolts 01 and first nuts 02. The through hole 305 of the second connecting rod 303 of the adjustable diagonal brace 30 is sleeved on the supporting steel bar 40. By tightening or loosening each adjustable diagonal brace 30, the verticality of the column reinforcement 10 can be adjusted until the verticality and positioning dimensions of the column reinforcement 10 are within the allowable error range, thereby achieving the purpose of preventing the column reinforcement 10 from deviating and fixing it. After the concrete pouring of the independent foundation 100 is completed, the fixing component 20 and the adjustable diagonal brace 30 can be removed by bolt 01 and first nut 02, so that the fixing component 20 and the adjustable diagonal brace 30 can be reused, which can save a lot of steel reinforcement materials.
[0028] The parts not described in detail in this technical solution specification are obvious to those skilled in the art and can be supplemented and improved based on existing technical knowledge. At the same time, those skilled in the art should understand that the above embodiments are merely preferred embodiments of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
