DETAILED DESCRIPTION

[0026] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0027] The following combination Figures 1 to 5 The utility model is described in detail.

[0028] A device for accurately positioning the main reinforcement of a cylindrical steel cage comprises a main body 1, a tooth block 101 being provided on the side wall of the main body 1, a plurality of positioning grooves 2 being provided on the side wall of the main body 1, a limiting component being provided in the middle of the positioning groove 2, fitting grooves 201 being provided on both sides of the opening of the positioning groove 2, and deflection grooves 202 being provided on both sides of the bottom of the positioning groove 2, the limiting component swinging along the axis, and the two ends of the limiting component cooperating with the fitting groove 201 and the deflection groove 202, the main body 1 being composed of several mutually spliced combinations, the depth of the positioning groove 2 being greater than the diameter of the main reinforcement 4 of the steel cage, and the positioning groove 2 being an opening passing through the side wall of the main body 1 from top to bottom.

[0029] First, the main reinforcement 4 of the steel cage is embedded in the positioning groove 2 so that the main body 1 can be connected to the main reinforcement 4 of the steel cage. Then, several segmented main bodies 1 are connected to the main reinforcement 4 of the steel cage to form a ring to replace the original reinforcing stirrups. The position of the positioning groove 2 is used to complete the limited positioning of the main reinforcement 4 of the steel cage so that it will not be displaced or deformed. Because the depth of the positioning groove 2 is larger than the diameter of the main reinforcement 4 of the steel cage, the space for pouring concrete will flow out, thereby forming a protective layer for the main reinforcement 4 of the steel cage.

[0030] Then the tooth blocks 101 provided on the side walls of the main body 1 will contact the cast formwork, and the tooth blocks 101 will reduce the contact surface with the formwork, allowing the concrete to penetrate into the gaps between the tooth blocks 101, thereby reducing the exposure of the main body 1. The main body 1 will drive the reinforcing stirrups to complete a more precise spacing positioning of the main reinforcement 4 of the steel cage, while also reducing the possibility of exposure.

[0031] At the same time, when the main reinforcement 4 of the steel cage is embedded in the positioning groove 2, because the limiting plate 3 is connected in the positioning groove 2 in a "V" shape, when the main reinforcement 4 of the steel cage is pushed in, it will abut against the two sides of the limiting plate 3. During the force application process, the limiting plate 3 will swing along the hinge axis 301 to separate the bottom so that the main reinforcement 4 of the steel cage can be pushed in. When the main reinforcement 4 of the steel cage is completely pushed into the positioning groove 2, the bottom part of the limiting plate 3 will deflect to the deflection groove 202 for cooperation, and at the same time, the main reinforcement 4 of the steel cage will contact the abutment block 302 to increase its cooperation with the limiting plate 3.

[0032] The top of the fitting block 303 and the fitting block 304 will gradually close together when the limiting plate 3 is gradually separated, so that the fitting block 304 will fit into the fitting groove 3031. When the fitting block 304 fits into the fitting groove 3031, the limiting blocks 3041 connected on both sides will be squeezed onto the squeezing protrusion 3032 through the squeezing inclined surface 3042 on one side, thereby forcing the limiting block 3041 to shrink into the groove, so that the fitting block 304 can be smoothly fitted into the fitting groove 3031. When it moves to the position of the limiting groove 3033, the limiting block 3041 will be reset due to the elasticity of the spring and embedded in the limiting groove 3033. At the same time, because the side of the limiting block 3041 away from the extrusion inclined surface 3042 is a plane, it will directly abut against the side of the extrusion protrusion 3032 away from the arc, so that the engaging block 304 cannot be separated, and the deflection angle of the limiting plate 3 cannot be changed, thereby limiting the main reinforcement 4 of the steel cage, so that the main reinforcement 4 of the steel cage will not be displaced outward along the positioning groove 2, resulting in inaccurate positioning.

[0033] Then there will be gaps to allow concrete to penetrate and complete the protective layer on the main reinforcement 4 of the steel cage.

[0034] Furthermore, the limiting component includes a limiting plate 3, a hinge shaft 301, a stopper 302, a fitting block 303 and a mosaic block 304. The limiting plate 3 is connected to both sides of the inner wall of the positioning groove 2. The hinge shaft 301 is arranged on the side where the limiting plate 3 fits the inner wall of the positioning groove 2. The stopper 302 is arranged at the bottom of the limiting plate 3, the fitting block 303 is arranged at the top of the limiting plate 3, and the mosaic block 304 is arranged at the top of the limiting plate 3. The limiting plate 3 is connected to both sides of the inner wall of the positioning groove 2 through the hinge shaft 301 on one side. Both sides of the inner wall of the positioning groove 2 are provided with protrusions that are hinged to the hinge shaft 301. The stopper 302 is arranged on the side opposite to the bottom of the limiting plate 3. The two stoppers 302 are staggered. The fitting block 303 and the mosaic block 304 are respectively arranged on the opposite sides of the two limiting plates 3. The fitting block 303 also includes There are a fitting groove 3031, an extrusion protrusion 3032 and a limiting groove 3033. The fitting groove 3031 is arranged on one side of the fitting block 303, the extrusion protrusion 3032 is arranged on both sides of the opening of the fitting groove 3031, and the limiting groove 3033 is arranged on both sides of the middle part of the fitting groove 3031. The extrusion protrusion 3032 is a direction protrusion on both sides of the opening of the fitting groove 3031, and the outward end of the extrusion protrusion 3032 is an arc-shaped arrangement. The fitting groove 3031 cooperates with the fitting block 304. The fitting block 304 also includes a limiting block 3041 and an extrusion inclined surface 3042. The limiting block 3041 is connected to the square blocks in the grooves at both ends of the fitting block 304 by a spring. The extrusion inclined surface 3042 is the inclined surface of the limiting block 3041 facing the side of the fitting groove 3031, and the limiting block 3041 cooperates with the limiting groove 3033.

[0035] At the same time, when the main reinforcement 4 of the steel cage is embedded in the positioning groove 2, because the limiting plate 3 is connected in the positioning groove 2 in a "V" shape, when the main reinforcement 4 of the steel cage is pushed in, it will abut against the two sides of the limiting plate 3. During the force application process, the limiting plate 3 will swing along the hinge axis 301 to separate the bottom so that the main reinforcement 4 of the steel cage can be pushed in. When the main reinforcement 4 of the steel cage is completely pushed into the positioning groove 2, the bottom part of the limiting plate 3 will deflect to the deflection groove 202 for cooperation, and at the same time, the main reinforcement 4 of the steel cage will contact the abutment block 302 to increase its cooperation with the limiting plate 3.

[0036] The top of the fitting block 303 and the fitting block 304 will gradually close together when the limiting plate 3 is gradually separated, so that the fitting block 304 will fit into the fitting groove 3031. When the fitting block 304 fits into the fitting groove 3031, the limiting blocks 3041 connected on both sides will be squeezed onto the squeezing protrusion 3032 through the squeezing inclined surface 3042 on one side, thereby forcing the limiting block 3041 to shrink into the groove, so that the fitting block 304 can be smoothly fitted into the fitting groove 3031. When it moves to the position of the limiting groove 3033, the limiting block 3041 will be reset due to the elasticity of the spring and embedded in the limiting groove 3033. At the same time, because the side of the limiting block 3041 away from the extrusion inclined surface 3042 is a plane, it will directly abut against the side of the extrusion protrusion 3032 away from the arc, so that the engaging block 304 cannot be separated, and the deflection angle of the limiting plate 3 cannot be changed, thereby limiting the main reinforcement 4 of the steel cage, so that the main reinforcement 4 of the steel cage will not be displaced outward along the positioning groove 2, resulting in inaccurate positioning.

[0037] Then there will be gaps to allow concrete to penetrate and complete the protective layer on the main reinforcement 4 of the steel cage.

[0038] The following is a specific implementation process of the present invention. First, the main reinforcement bar 4 of the steel cage is embedded in the positioning groove 2 so that the main body 1 can be connected to the main reinforcement bar 4 of the steel cage. Then, the segmented main bodies 1 are connected to the main reinforcement bar 4 of the steel cage to form a ring, replacing the original reinforcing stirrups. The position of the positioning groove 2 is used to complete the limited positioning of the main reinforcement bar 4 of the steel cage so that it will not be displaced or deformed. Because the depth of the positioning groove 2 is larger than the diameter of the main reinforcement bar 4 of the steel cage, the space for pouring concrete will flow out, thereby forming a protective layer for the main reinforcement bar 4 of the steel cage. Then, the tooth block 101 set on the side wall of the main body 1 will contact the pouring template, and the tooth block 101 set on the side wall of the main body 1 will contact the pouring template. The tooth blocks 101 are used to reduce the contact surface with the template, allowing concrete to penetrate into the gaps between the tooth blocks 101, thereby reducing the exposure of the main body 1. The main body 1 is used to drive the reinforcing stirrups to complete a more accurate spacing positioning of the main reinforcement cage 4, while also reducing the possibility of exposure. At the same time, when the main reinforcement cage 4 is embedded in the positioning groove 2, because the limiting plate 3 is connected to the positioning groove 2 in a "V" shape, when the main reinforcement cage 4 is pushed in, it will abut against both sides of the limiting plate 3. In the process of applying force, the limiting plate 3 will swing along the hinge axis 301 to separate the bottom, so that the main reinforcement cage 4 can be pushed in. After the main reinforcement 4 of the reinforcement cage is completely pushed into the positioning groove 2, the bottom part of the limiting plate 3 will deflect to the deflection groove 202 for cooperation. At the same time, the main reinforcement 4 of the reinforcement cage will contact the stop block 302 to increase its cooperation with the limiting plate 3. Then, when the limiting plate 3 is gradually separated below, the top of the fitting block 303 and the embedding block 304 will gradually close together, so that the embedding block 304 will be embedded in the embedding groove 3031. When the embedding block 304 is embedded in the embedding groove 3031, the limiting blocks 3041 connected on both sides will be squeezed onto the extrusion protrusion 3032 through the extrusion inclined surface 3042 on one side, thereby forcing the limiting block 3041 to The locking plate 3031 is locked and the locking plate 3032 is unlocked, so the locking plate 3032 is unlocked.

[0039] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
