DETAILED DESCRIPTION

[0026] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Combine the following Figures 1 to 5 The present invention 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 is provided on the side wall of the main body 1, a plurality of positioning grooves 2 are provided on the side wall of the main body 1, a limiting component is provided in the middle of the positioning groove 2, fitting grooves 201 are provided on both sides of the opening of the positioning groove 2, deflection grooves 202 are provided on both sides of the bottom of the positioning groove 2, the limiting component swings along the axis, and the two ends of the limiting component cooperate with the fitting groove 201 and the deflection groove 202. The main body 1 is composed of a plurality of mutually spliced ​​combinations, the depth of the positioning groove 2 is greater than the diameter of the main reinforcement 4 of the steel cage, and the positioning groove 2 is an opening that passes 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 into the positioning groove 2 so that the main body 1 can be connected to the main reinforcement 4 of the steel cage, and 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 main reinforcement 4 of the steel cage is positioned to prevent displacement and deformation. Because the depth of the positioning groove 2 is larger than the diameter of the main reinforcement 4 of the steel cage, the concrete will flow out of the space for pouring, thereby forming a protective layer for the main reinforcement 4 of the steel cage.

[0030] Then the tooth block 101 arranged on the side wall of the main body 1 will contact the cast formwork, and the tooth block 101 will reduce the contact area with the formwork, allowing the concrete to penetrate into the gap 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 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 will be 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] Then, when the lower part of the limiting plate 3 is gradually separated, the tops of the fitting block 303 and the embedding block 304 are gradually closed together, so that the embedding block 304 is 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 are squeezed onto the extrusion protrusion 3032 through the extrusion inclined surface 3042 on one side, thereby forcing the limiting block 3041 to shrink into the groove, so that the embedding block 304 can be smoothly embedded in the embedding groove 3031, and then when the moving plate 3 is moved, the locking plate 3041 is locked. 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 move 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 for the main reinforcement 4 of the steel cage.

[0034] Furthermore, the limiting component includes a limiting plate 3, a hinge axis 301, a stopper 302, a fitting block 303 and an interlocking block 304. The limiting plate 3 is connected to both sides of the inner wall of the positioning groove 2. The hinge axis 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. The interlocking 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 a hinge axis 301 on one side. Both sides of the inner wall of the positioning groove 2 are provided with protrusions that are hinged with the hinge axis 301. The stopper 302 is arranged on the side opposite to the bottom of the limiting plate 3. The two stoppers 302 are arranged in a staggered manner. The fitting block 303 and the interlocking block 304 are respectively arranged on the opposite sides of the two limiting plates 3. The fitting block 303 also includes There are an engaging groove 3031, an extrusion protrusion 3032 and a limiting groove 3033. The engaging 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 engaging groove 3031, and the limiting groove 3033 is arranged on both sides of the middle part of the engaging groove 3031. The extrusion protrusion 3032 is a direction protrusion on both sides of the opening of the engaging groove 3031, and the outward end of the extrusion protrusion 3032 is arranged in an arc shape. The engaging groove 3031 cooperates with the engaging block 304. The engaging block 304 also includes a limiting block 3041 and an extrusion inclined surface 3042. The limiting block 3041 is connected to the square block in the grooves at both ends of the engaging block 304 through a spring. The extrusion inclined surface 3042 is an inclined surface of the limiting block 3041 facing the side of the engaging 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 will be 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] Then, when the lower part of the limiting plate 3 is gradually separated, the tops of the fitting block 303 and the embedding block 304 are gradually closed together, so that the embedding block 304 is 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 are squeezed onto the extrusion protrusion 3032 through the extrusion inclined surface 3042 on one side, thereby forcing the limiting block 3041 to shrink into the groove, so that the embedding block 304 can be smoothly embedded in the embedding groove 3031, and then when the moving plate 3 is moved, the locking plate 3041 is locked. 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 move 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 for the main reinforcement 4 of the steel cage.

[0038] The following is a specific implementation process of the present invention. First, the main reinforcement 4 of the steel cage is embedded into the positioning groove 2 so that the main body 1 can be connected to the main reinforcement 4 of the steel cage. Then, the segmented main bodies 1 are connected to the main reinforcement 4 of the steel cage to form a ring of the main body 1 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 and 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. Then, the tooth block 101 set on the side wall of the main body 1 will contact the casting template, and through The tooth block 101 is used to reduce the contact surface with the template, so that the concrete can penetrate into the gap between the tooth blocks 101, thereby reducing the exposure of the main body 1, and driving the reinforcing stirrups through the main body 1 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 cage is completely pushed into the positioning groove 2, the bottom part of the limiting plate 3 will be deflected into the deflection groove 202 for cooperation, and at the same time, the main reinforcement 4 of the steel cage will contact the stop block 302 to increase its cooperation with the limiting plate 3, and then when the limiting plate 3 is gradually separated below, the tops 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, and 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 retracted into the groove to allow the engaging block 304 to be smoothly engaged with the engaging groove 3031. Then, 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 engaged with 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.
