For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood based on specific circumstances.

[0039] Reference Attachment Figure 1-6, this embodiment provides a movable anchor bolt group and shear groove positioning device, which includes: a guide rail 1, a movable frame 2, a positioning plate 3 and a telescopic member 4, wherein the guide rail 1 is provided with two groups correspondingly, and is arranged according to the arrangement direction of the anchor bolt group, specifically: a plurality of anchor bolt groups are distributed along a straight line on the foundation cushion layer, and the extension direction of the guide rail 1 is the same as the extension direction of the straight line. The purpose is to complete the arrangement of a plurality of collinearly distributed anchor bolt groups by moving other components without disassembling the guide rail 1, so as to improve the construction efficiency and construction accuracy; the movable frame 2 can be movably arranged It is placed on the guide rail 1, which is a cubic grid structure with a vacant middle part to temporarily accommodate the anchor bolts 13; the positioning plate 3 is located on the top of the mobile frame 2, and is provided with anchor bolt holes 3.1 and shear slot holes 3.2 located between the two sets of guide rails 1. The anchor bolt holes 3.1 are used to temporarily suspend the anchor bolts 13, and the shear slot holes 3.2 are used to accurately position the shear slot template 14; the telescopic member 4 is located between the mobile frame 2 and the positioning plate 3, and its two ends are respectively connected to the mobile frame 2 and the positioning plate 3. It can adjust the distance between the positioning plate 3 and the mobile frame 2 by changing its own length, thereby raising and lowering the height of the positioning plate 3.

[0040] According to construction requirements, precisely positioned anchor bolt holes 3.1 and shear slots 3.2 are pre-opened on the positioning plate 3. Generally, the anchor bolt holes 3.1 are arranged in a ring around the shear slots 3.2. However, the distribution density of the anchor bolt holes 3.1 and the spacing between them and the shear slots 3.2 vary depending on construction requirements. Therefore, various types of positioning plates 3 can be pre-configured.

[0041] The operating principle of this positioning device is as follows: place the guide rail 1 on the foundation cushion, install the mobile frame 2 on the guide rail 1, and then install the telescopic member 4 and the positioning plate 3 in sequence; extend the telescopic member 4 so that the positioning plate 3 is in a high position, and after the top of the anchor bolt 13 passes through the anchor bolt hole 3.1, fix it with a matching nut; move the mobile frame 2 and the anchor bolt group to the target installation point, use a laser instrument and other equipment to detect the positioning accuracy of the anchor bolt group, after accurate positioning, fix the mobile frame 2, shorten the telescopic member 4, and gradually lower the positioning plate 3 to a low position, and the anchor bolt group then drops to the target installation point on the foundation cushion, and meets the support angle steel and fixed angle steel on the target installation point. The shear groove template 14 is connected and fixed with a positioning steel plate (a fixing component commonly used when pre-embedded anchor bolts); the shear groove template 14 is placed close to the inner wall of the shear groove hole 3.2, and the limiting steel (or limiting steel bar) is welded or tied to the anchor bolt 13 so that part of the limiting steel is surrounded by the outside of the shear groove template 14 and pressed against the shear groove template 14 to complete the positioning and placement of a group of anchor bolt groups and shear groove templates 14; the matching nuts on the positioning plate 3 used to temporarily fix the anchor bolts 13 are removed, the telescopic part 4 is extended until the positioning plate 3 is completely separated from the anchor bolts 13, and the movable frame 2 is moved a distance along the guide rail 1 to position and place the next group of anchor bolt groups and shear groove templates 14.

[0042] By adopting this positioning device, by prefabricating a positioning plate 3 that meets the construction requirements (specifically the accuracy of the anchor bolt hole 3.1 and the shear slot hole 3.2), the distribution accuracy of multiple anchor bolts in the anchor bolt group and the distribution accuracy of the shear slot in the center of the anchor bolt group are controlled, thereby improving the placement accuracy and placement efficiency; through the cooperation of the guide rail 1 and the movable frame 2, after the guide rail 1 is accurately placed, multiple groups of anchor bolts distributed along a straight line can be placed in batches, thereby improving the placement accuracy and placement efficiency.

[0043] refer to Figure 2 The mobile frame 2 in this embodiment includes vertical supports 2.1, transverse supports 2.2 and diagonal supports 2.3. There are 4 vertical supports 2.1, two of which are arranged side by side in each guide rail 1. The bottom is connected to the guide rail 1 through a walking wheel 5, and the walking wheel 5 is movably arranged in the guide rail 1. In order to facilitate the fixation of the mobile frame 2, the walking wheel 5 can be optionally equipped with a self-locking function; the transverse support 2.2 is located between adjacent vertical supports 2.1, and the two ends are respectively connected to the adjacent vertical supports 2.1, thereby forming a cubic grid structure; the diagonal support 2.3 is also located between adjacent vertical supports 2.1, and every two diagonal supports 2.3 are crossed in an X shape, and the two sides are respectively connected to the adjacent vertical supports 2.1, so as to improve the stability of the mobile frame 2. After one set of anchor bolts is installed, the mobile frame 2 needs to be moved along the guide rail 1. To prevent the diagonal braces 2.3 from interfering with the installed anchor bolts, which would prevent the mobile frame 2 from being able to move, diagonal braces 2.3 can be installed only on the side of the mobile frame 2 parallel to the guide rail 1. Additional diagonal braces 2.3 can also be installed on the remaining side surfaces of the mobile frame 2 that are close to the positive direction of movement. The positive direction of movement specifically refers to: when multiple sets of anchor bolts are distributed along a straight line, the anchor bolts are generally installed sequentially from one end of the straight line to the other end, and the side where the anchor bolts are not yet installed is the positive direction of movement (the same applies to the installation of the cross braces 2.2). Of course, since the cross braces 2.2 have a simple structure and are easy to install and remove, if the cross braces 2.2 are connected to the vertical braces 2.1 using fasteners, cross braces 2.2 can be installed on all four sides of the mobile frame 2. When the position of the mobile frame 2 on the guide rail 1 needs to be changed, the cross brace 2.2 on the obstructed side can be removed.

[0044] The vertical support 2.1, horizontal support 2.2 and diagonal support 2.3 can all be made of steel pipe structure, especially the vertical support 2.1, so as to facilitate the installation of the telescopic member 4 selected in this embodiment. Figure 3The telescopic part 4 in the embodiment includes a vertical screw 4.1 and a T-shaped screw sleeve 4.2. The bottom end of the vertical screw 4.1 is slidably arranged in the vertical support 2.1. The T-shaped screw sleeve 4.2 is sleeved on the vertical screw 4.1 and at least partially abuts against the outside of the vertical support 2.1. That is, the bottom edge of the T-shaped screw sleeve 4.2 can abut against the top of the vertical support 2.1, or a segment with a smaller outer diameter can be inserted into the vertical support 2.1 and a segment with a larger outer diameter can abut against the top of the vertical support 2.1. The position of the T-shaped screw sleeve 4.2 is fixed but rotatable. When the T-shaped screw sleeve is rotated, the vertical screw 4.1 can be telescopically extended in and out of the vertical support 2.1, thereby changing the height of the positioning plate 3.

[0045] To improve the stability of the positioning plate 3, the top of the vertical screw 4.1 is provided with a mounting plate 6. The extension direction of the mounting plate 6 is perpendicular to the guide rail 1. The bottom surface of the mounting plate 6 is arranged on the top of the vertical screw 4.1 and is welded and fixed to the top end of the vertical screw 4.1. Of course, the mounting plate 6 can also be directly replaced by a channel steel. The channel steel is buckled on the top end of the vertical screw 4.1. The middle part of the channel steel serves as the mounting plate 6. The two ends of the channel steel can be further improved in stability outside the vertical screw 4.1. Figure 4 A straight slot 6.1 is arranged on the mounting plate 6. The straight slot 6.1 extends in a direction perpendicular to the guide rail 1. High-strength bolts 7 for connecting the positioning plate 3 are arranged in the straight slot 6.1.

[0046] Before the anchor bolt group is lowered, the position of the anchor bolt group needs to be accurately checked. If the assembly accuracy of some components in the positioning device is poor and the mounting plate 6 and the positioning plate 3 are connected in a one-to-one manner through common circular holes, the final installation accuracy of the anchor bolt group cannot be guaranteed. However, the straight slot 6.1 arranged above can solve this problem. During the lowering of the anchor bolt group, the positioning plate 3 can be moved along the straight slot 6.1. After the position of the anchor bolt group is finely adjusted, the high-strength bolts 7 are used for fixation, so as to ensure accurate installation.

[0047] Reference Figure 5 To improve the connection stability of the moving frame 2 and the anchor bolt and prevent the anchor bolt from loosening due to shaking when the moving frame 2 is finely adjusted, the anchor bolt support plate 8 is further arranged. The anchor bolt support plate 8 extends in a direction perpendicular to the guide rail 1 and is slidably arranged on a set of opposite cross supports 2.2. The bottom of the anchor bolt support plate 8 is provided with a rib plate 9. The rib plate 9 is provided with locking members 10 connected to the cross supports 2.2. The anchor bolt support plate 8 can slide on the cross supports 2.2 in the extension direction of the guide rail 1 to align the anchor bolts in the anchor bolt group. Then, the locking members 10 are used for fixation, so as to provide stable support for the anchor bolts. It should be noted that the anchor bolt support plate 8 should be slid away or removed during the process of lowering and installing the anchor bolt group.

[0048] The locking member 10 includes a push rod 10.1, a rotary handle 10.2, and an abutment plate 10.3. The push rod 10.1 is provided on the rib 9 and is threadedly connected to the rib 9. The rotary handle 10.2 and the abutment plate 10.3 are respectively located at the two ends of the push rod 10.1. The abutment plate 10.3 is close to the cross brace 2.2, and its shape is adapted to the shape of the cross brace 2.2. For example, if the cross brace 2.2 is a round steel tube, the abutment plate 10.3 can be an arc-shaped plate. If the cross brace 2.2 is a square steel tube, the abutment plate 10.3 can be a straight plate or a C-shaped plate. When the rotary handle 10.2 is rotated to move the abutment plate 10.3 away from the cross brace 2.2, the anchor bolt support plate 8 is loosened and can slide. When the rotary handle 10.2 is rotated in the opposite direction to make the abutment plate 10.3 press against the cross brace 2.2, the anchor bolt support plate 8 is locked and cannot slide.

[0049] In addition, a slide groove 11 extending in the same direction as the guide rail 1 can be opened on the top surface of the cross brace 2.2, and a slider 12 is provided at the bottom of the anchor bolt support plate 8. The slider 12 is slid into the slide groove 11 to further improve the connection stability between the cross brace 2.2 and the anchor bolt support plate 8.

[0050] The method for accurately placing the anchor bolt group and the shear groove template 14 using the positioning device includes the following steps:

[0051] (1) Place the guide rail 1 on the foundation cushion, install the mobile frame 2 on the guide rail 1, and then install the telescopic member 4, positioning plate 3 and anchor bolt support plate 8 in sequence;

[0052] (2) Extend the telescopic member 4 so that the positioning plate 3 is in the highest position. Pass the top of the anchor bolt 13 through the anchor bolt hole 3.1 and secure it with the matching nut. Move the anchor bolt support plate 8 to the bottom of the anchor bolt 13 and lock it with the locking member 10.

[0053] (3) Move the mobile frame 2 and the anchor bolt group to the target installation point, use a laser instrument or other equipment to detect the accuracy of the anchor bolt group, and after accurate positioning, fix the mobile frame 2 and remove the anchor bolt support plate 8; shorten the telescopic member 4 to gradually lower the positioning plate 3 to a low position, and then lower the anchor bolt group to the target installation point on the foundation cushion layer, and connect and fix it with the support angle steel, positioning steel plate (a commonly used fixing component when pre-embedded anchor bolts) and other components on the target installation point;

[0054] (4) Place the shear groove template 14 close to the inner wall of the shear groove hole 3.2, weld or tie the limiting steel (or limiting steel bar) on the anchor bolt 13, refer to Figure 6 , so that part of the limiting steel is arranged on the outside of the shear groove template 14 and is tightly pressed against the shear groove template 14, and the positioning and placement of a set of anchor bolts and the shear groove template 14 can be completed;

[0055] (5) dismounting the matched nut for temporarily fixing the anchor bolt on the positioning plate 3, extending the telescopic piece 4 to completely separate the positioning plate 3 from the anchor bolt 13, moving the movable frame 2 along the guide rail 1 by a distance, and positioning and arranging the next group of anchor bolt groups and the shear groove formwork 14.

[0056] Compared with the prior art, the utility model has the beneficial effects that: by prefabricating the positioning plate 3 (specifically referring to the precision of the anchor bolt hole 3.1 and the shear groove hole 3.2) meeting the construction requirements, the distribution precision of multiple anchor bolts in the anchor bolt group and the distribution precision of the shear groove in the center of the anchor bolt group are controlled, and the arrangement precision and arrangement efficiency are improved; by the cooperation of the guide rail 1 and the movable frame 2, after accurately arranging the guide rail 1, multiple groups of anchor bolt groups distributed along a straight line can be arranged in batches, and the arrangement precision and arrangement efficiency are improved.
