Description

Technical Field

[0001] The utility model relates to the technical field of construction accessories, in particular to a vertical steel bar fixing device. Background Art

[0002] In research on process measures for ensuring the qualified rate of concrete cover, the stable fixation of vertical reinforcement plays multiple roles, all of which are directly related to the overall performance, safety, and durability of the concrete structure. During the construction of the concrete cover, the vertical reinforcement primarily serves to resist tension. Its stable fixation ensures that when subjected to external tension, the reinforcement and concrete work together to resist the tension, thereby enhancing the overall tensile strength of the structure. The stable fixation of the vertical reinforcement reduces adjustments and repairs during construction. Every step in the construction process is directly related to the final quality of the concrete cover. Uniformity during mixing, density during pouring, and subsequent maintenance measures are all key links in ensuring the strength and density of the cover.

[0003] When arranging vertical steel bars, they are usually composed of four groups of roots to form a steel cage, which is convenient for subsequent concrete pouring. When arranging the four vertical steel bars, they are wrapped around and tied on the vertical steel bars to fix the vertical steel bars. At some nodes, transverse steel bars are added to tie them together with the vertical steel bars, and the vertical steel bars are directly tied to the transverse steel bars. When fixing the existing vertical steel bars, bent steel bars and steel wires are used for combination and fixation, which requires multiple points of fixation. The operation is cumbersome, and the operational stability still needs to be improved.

[0004] In view of the above problems, a vertical steel bar fixing device is proposed. Utility Model Content

[0029] See also Figure 1-Figure 3 In this embodiment, a vertical steel bar fixing device includes a positioning cylinder 10, a first fixing rod 20 and a second fixing rod 30;

[0030] One side of the positioning cylinder 10 is provided with an opening, and both ends of the positioning cylinder 10 near the opening are connected to extension plates 11, and fixing members are connected to the extension plates 11 for adjusting the two groups of extension plates 11 to move closer or farther away;

[0031] The first fixing rod 20 and the second fixing rod 30 are staggered. The first fixing rod 20 is provided with a plurality of first fixing grooves 22, and the second fixing rod 30 is provided with a plurality of second fixing grooves 31.

[0032] In this embodiment, the opening of the positioning tube 10 can be aligned with the vertical steel bar, and the positioning tube 10 can be clamped on the vertical steel bar. According to the fixing situation, if the vertical steel bar needs to be fixed at the target node, the two sets of extension plates 11 can be adjusted to be close together through the fixing piece, so that the positioning tube 10 is fixed on the vertical steel bar, and then the positioning tube 10 on the other vertical steel bar is clamped, so that the first fixing rod 20 and the second fixing rod 30 are staggered. Figure 1 As shown, the contact portion of the first fixing rod 20 and the second fixing rod 30 can be adjusted according to the distance between the two groups of vertical steel bars. After the positioning cylinder 10 is fixed, the first fixing rod 20 and the second fixing rod 30 can be tied together and fixed, which is convenient for operation and use and is conducive to the fixation of the vertical steel bars.

[0033] When the transverse reinforcement is overlapped on the vertical reinforcement for fixing, a set of positioning cylinders 10 can be fixed to bind the transverse reinforcement with the first fixing rod 20 or the second fixing rod 30 to achieve the connection and fixation of the transverse reinforcement and the vertical reinforcement.

[0034] In another embodiment, the fixing member includes a hexagonal head 14 and a screw 13 fixedly connected to the hexagonal head 14, wherein one group of the extension plates 11 is provided with a through hole rotatably engaged with the screw 13, and another group of the extension plates 11 is connected to a threaded tube 12, and the threaded tube 12 is threadedly engaged with the screw 13;

[0035] The hexagonal head is rotated to drive the screw 13 to rotate in the threaded tube 12, and the distance between the two groups of extension plates 11 can be adjusted, so that the positioning cylinder 10 can clamp the steel bar.

[0036] In another embodiment, a hexagonal groove is provided on the side of the hexagonal head 14 away from the screw 13; the hexagonal head 14 can be rotated using a tool, and the setting of the hexagonal groove makes it convenient to use the inner hexagon to rotate the hexagonal head 14, thereby improving the applicability of the device.

[0037] In another embodiment, a plurality of clamping grooves 21 are provided on a side of the first fixing rod 20 away from the first fixing groove 22 , and the fixing wires 40 are clamped in the clamping grooves 21 ;

[0038] After the first fixing rod 20 and the second fixing rod 30 are docked, the fixing wire 40 can be used to connect the first fixing rod 20 and the second fixing rod 30 . The clamping groove 21 can play a limiting role, facilitating the stable connection of the fixing wire 40 .

[0039] like Figure 3 As shown, in another embodiment, the inner wall of the positioning tube 10 is fixedly connected to an anti-slip pad 15; the provision of the anti-slip pad 15 can improve the stability of the connection between the positioning tube 10 and the steel bar.

[0040] like Figure 1As shown, in another embodiment, four groups of positioning cylinders 10 are provided; in actual use, the four groups of positioning cylinders 10 can be fixed on corresponding steel bars respectively, and then the first fixing rod 2 and the second fixing rod 30 are connected.

[0041] In another embodiment, the angle between the first fixing rod 20 and the second fixing rod 30 connected to the positioning cylinder 10 is 80 to 95 degrees; the angle between the first fixing rod 20 and the second fixing rod 30 will change due to the size of the opening of the positioning cylinder 10; after the opening of the positioning cylinder 10 is fixed, the positions of the first fixing rod 20 and the second fixing rod 30 can be fixed.

[0042] The working principle of the present invention is as follows: the opening of the positioning cylinder 10 can be aligned with the vertical steel bar, and the positioning cylinder 10 can be clamped on the vertical steel bar. According to the fixing situation, if the vertical steel bar needs to be fixed at the target node, the hexagonal head is rotated to drive the screw 13 to rotate in the threaded tube 12, and the distance between the two sets of extension plates 11 can be adjusted, so that the positioning cylinder 10 clamps the steel bar, and then the positioning cylinder 10 is clamped on another vertical steel bar, so that the first fixing rod 20 and the second fixing rod 30 are staggered. Figure 1 As shown, according to the distance between the two groups of vertical steel bars, the contact portion of the first fixing rod 20 and the second fixing rod 30 can be adjusted. After the positioning cylinder 10 is fixed, the first fixing rod 20 and the second fixing rod 30 can be connected using the fixing wire 40. The clamping groove 21 can play a limiting role, facilitating the stable connection of the fixing wire 40. After that, the fixing wire 40 is wound and can be wound around the first fixing groove 22 and the second fixing groove 31, which is convenient for operation and use and is conducive to the fixation of the vertical steel bars.

[0043] When the transverse reinforcement is overlapped on the vertical reinforcement for fixing, a set of positioning cylinders 10 can be fixed to bind the transverse reinforcement with the first fixing rod 20 or the second fixing rod 30 to achieve the connection and fixation of the transverse reinforcement and the vertical reinforcement.

[0044] During the construction of the concrete protective layer, the stable fixation of the vertical steel bars is conducive to the pouring of concrete. At the same time, the quality of the raw materials of the concrete should be strictly controlled. The uniformity during the mixing process, the density during pouring, the stability of the structure and the subsequent maintenance measures are all key links to ensure the strength and density of the protective layer.
