[0020] The clamping mechanism 2 includes a first fixed block 201, a first sliding groove 202, a first bolt 203, a first sliding block 204, a second fixed block 205, a second sliding groove 206, a second sliding block 207, a first connecting block 208, a first fixed plate 209, a third fixed block 210, a third connecting block 211, a second fixed plate 212, a screw rod 213 and a handle 214.

During use, when it is necessary to position the steel bar during the process of making the concrete precast component, a set of clamping mechanisms 2 is taken as an example. A steel bar can be placed between the first connecting block 208 and the third connecting block 211, and then the handle 214 is manually rotated. The rotation of the handle 214 can drive the second sliding block 207 to move. At this time, the second sliding block 207 can slide in the second sliding groove 206 and move with the third connecting block 211 and the second fixing plate 2 12 cooperate with each other. When the first fixing plate 209 and the second fixing plate 212 clamp the steel bar between the first connecting block 208 and the third connecting block 211, stop turning the handle 214 to complete the fixation of one steel bar. Then, manually loosen the nuts of the two groups of first bolts 203, and then drive the second fixing block 205 to drive the first sliding block 204 to slide on the first fixing block 201, so as to adjust the distance between the two groups of second fixing blocks 205, thereby achieving the effect of adjusting the distance between the two steel bars. The clamping mechanism 2 can be continuously set to multiple groups for use in combination, so as to meet the steel bar positioning requirements of precast concrete components.

[0021] Furthermore, the first sliding block 204 is slidably connected to the first fixed block 201 through the first sliding groove 202 and the first bolt 203, and the screw rod 213 is bearing-connected to the second fixed block 205.

Through the arrangement of the screw rod 213 and the third fixing block 210, the steel bars can be fixed normally between the first fixing plate 209 and the second fixing plate 212, which is beneficial to the fixing of the steel bars of the precast concrete component by the clamping mechanism 2.

[0023] Furthermore, the connecting mechanism 6 includes a fourth fixing block 601, a third bolt 602, a positioning groove 603, a connecting rod 604, a first through hole 605, a fifth fixing block 606, a second through hole 607 and a fourth bolt 608. The surface of one end of the fourth connecting block 3 is fitted with the fourth fixing block 601, the surface inside the fourth fixing block 601 is threadedly connected with the third bolt 602, one end of the fourth fixing block 601 is provided with a positioning groove 603, one side of the fourth fixing block 601 is fixedly connected with the connecting rod 604, both sides of the connecting rod 604 are provided with a first through hole 605, the other side of the connecting rod 604 is fixedly connected with the fifth fixing block 606, both ends of the fifth fixing block 606 are provided with a second through hole 607, and the other side of the fifth fixing block 606 is fixedly connected with the fourth bolt 608. During use, when it is necessary to place When placing longitudinal reinforcement in the z-axis direction, assuming that the first group of fixed bases 1 are placed on the x-axis, the second bolt 4 of the first fixed base 1 is fixed to the fourth fixed block 601. At this time, the second bolt 4 of the second group of fixed bases 1 can be connected to the second through hole 607, and then the second bolt 4 is tightened to complete the fixation, and the operation of the clamping mechanism 2 is repeated to adjust or fix the longitudinal reinforcement in the z-axis direction. If it is necessary to place the reinforcement in the y-axis direction on this basis, the second bolt 4 of the third group of fixed bases 1 can be connected to the first through hole 605, and then the second bolt 4 is tightened to complete the fixation. The operation of the clamping mechanism 2 is repeated to adjust or fix the reinforcement in the y-axis direction. If the fixed base 1 in a certain direction needs to be extended, it is only necessary to connect the second bolt 4 of other groups of fixed bases 1 to the fifth connecting block 5 of the previous fixed base 1 to complete the extension.

[0024] Furthermore, the fourth connecting block 3 is slidably connected to the positioning groove 603, and the fourth connecting block 3 is threadedly connected to the third bolt 602. Through the setting of the fourth connecting block 3 and the positioning groove 603, the connecting mechanism 6 can be fixedly connected to the fixed base 1, and multiple groups of fixed bases 1 can be connected and coordinated with each other to adapt to different precast concrete component steel bars. Through the setting of the fourth connecting block 3 and the third bolt 602, the third bolt 602 can fix the connecting mechanism 6 and the fixed base 1, thereby improving the adaptability of the precast concrete component steel bar positioning structure.

Through the arrangement of the first through hole 605, the fifth fixing block 606 and the second bolt 4, multiple groups of fixed bases 1 can be connected to each other in all directions, which increases the connection methods between the connecting mechanism 6 and the fixed base 1 and improves the production efficiency of precast concrete components.

[0026] Working principle: During use, when it is necessary to position the steel bars during the process of making precast concrete components, a set of clamping mechanisms 2 is taken as an example. A steel bar can be placed between the first connecting block 208 and the third connecting block 211, and then the handle 214 is manually turned. The rotation of the handle 214 can drive the second sliding block 207 to move. At this time, the second sliding block 207 can slide in the second sliding groove 206 and cooperate with the third connecting block 211 and the second fixing plate 212. When the first fixing plate 209 and the second fixing plate 212 clamp the steel bar between the first connecting block 208 and the third connecting block 211, stop turning the handle 214 to complete the fixation of a steel bar, and then manually loosen the nuts of the two sets of first bolts 203, and then drive the second fixing block 205 to drive the first sliding block 204 to slide on the first fixing block 201, so as to adjust the distance between the two sets of second fixing blocks 205, thereby achieving the effect of adjusting the distance between the two steel bars. The clamping mechanism 2 can be set with multiple sets in succession. The two fixing blocks 601 and 602 are used together to meet the needs of steel bar positioning of precast concrete components. When the longitudinal bars in the z-axis direction need to be placed, assuming that the first group of fixed bases 1 are placed on the x-axis, the second bolts 4 of the first fixed base 1 are fixed to the fourth fixed block 601. At this time, the second bolts 4 of the second group of fixed bases 1 can be connected to the second through holes 607, and then the second bolts 4 are tightened to complete the fixation. The operation of the clamping mechanism 2 can be repeated to adjust or fix the longitudinal bars in the z-axis direction. If the steel bars in the y-axis direction need to be placed on this basis, the second bolts 4 of the third group of fixed bases 1 can be connected to the first through holes 605, and then the second bolts 4 are tightened to complete the fixation. The operation of the clamping mechanism 2 can be repeated to adjust or fix the steel bars in the y-axis direction. If the fixed base 1 in a certain direction needs to be extended, the second bolts 4 of the other groups of fixed bases 1 only need to be connected to the fifth connecting block 5 of the previous fixed base 1 to complete the extension. This steel bar positioning structure can quickly and effectively complete the fixed positioning of the steel bars and improve the stability of the steel bar fixation.
