Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an anti-collision inspection device for exposed column foot anchor bolts and short column stirrups. Background Art

[0002] At present, the construction of exposed column foot anchor bolts is to tie the short column stirrups first, and then bury the anchor bolts when reaching the top of the short column. However, due to the deviation between the position of the short column stirrups and the theoretical position during the process of tying the short column stirrups, the theoretical positioning position of the anchor bolt and the actual position of the short column stirrups are prone to conflict. Since the position of the stirrups is fixed, the anchor bolts are often offset, resulting in a large deviation between the positioning of the anchor bolts and the position of the hole opening of the steel column foot plate. At this time, the short column has been cast, and the steel column foot plate needs to be returned to the factory for re-expansion, which delays the construction period to a certain extent and causes great economic losses. Utility Model Content

[0003] The purpose of the utility model is to provide an anti-collision inspection device for exposed column foot anchor bolts and short column stirrups, so as to solve the problem of interference between the theoretical positioning position of the anchor bolts and the actual position of the short column stirrups, reduce the number of subsequent rework of the footing plate, improve the connection efficiency of the short column and the steel column, and reduce the economic losses caused by rework.

[0004] To achieve the above purpose, the utility model is implemented through the following technical solutions:

[0009] Furthermore, the frame is provided with a plurality of grooves connected with the slide grooves, the slider is provided with balls in contact with the grooves, and a spring is provided between two of the balls.

[0010] Furthermore, the slider is symmetrically provided with wedge blocks, one side of the wedge blocks is provided with an arc groove in contact with the ball bearing, the spring is arranged between the two wedge blocks, the slider is threadedly connected with a screw, and the screw is provided with a conical surface in contact with the wedge blocks.

[0011] Furthermore, the frame is formed by welding eight flat steels alternately arranged up and down, and the slide groove is located between the upper and lower adjacent flat steels.

[0012] Furthermore, the flat steel located on the upper side is provided with scale lines.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. By sliding a slider on the frame, the corresponding pull rope is driven to move on the frame, and the intersection of the corresponding pull rope and the other pull ropes is changed to form an anchor placement area. The above steps are repeated to make each anchor placement area correspond to the theoretical position of anchor bolts with different outer diameters.

[0025] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that these equivalent forms also fall within the scope defined in this application.

[0026] An anti-collision inspection device for exposed column foot anchor bolts and short column stirrups, such as Figure 2 、 Figure 3 and Figure 4 As shown, it includes a frame 2 placed on a short column 1, and the short column 1 includes longitudinal reinforcement 3 and stirrups 4. The frame 2 is provided with a plurality of mutually perpendicular slide grooves 5, and a plurality of sliders 6 are slidably connected in the plurality of slide grooves 5. A pull rope 7 is provided between two corresponding sliders 6, and the intersection of two adjacent groups of the pull ropes 7 and the remaining pull ropes 7 forms an anchor placement area 8. By sliding the slider 6 on the frame 2, the corresponding pull rope 7 is driven to move on the frame 2, and the intersection of the corresponding pull rope 7 and the remaining pull rope 7 is changed to form an anchor placement area 8. Repeat the above steps to theoretically connect each anchor placement area 8 with the anchor bolts 22 of different outer diameters. The positions correspond to each other, which can meet the needs of different types of anchor bolts 22. There is no need to separately manufacture anti-collision inspection devices of different specifications, reducing the cost required for manufacturing anti-collision inspection devices; the frame 2 is placed on the base surface of the short column 1, and the area that will interfere with the anchor bolts 22 is clearly defined. In the subsequent construction process of the longitudinal reinforcement 3 and the stirrups 4, the anchor placement area 8 is avoided to avoid the longitudinal reinforcement 3 and the stirrups 4 after the construction is completed from interfering with the theoretical position of the anchor bolts 22. There is no need to move the position of the anchor bolts 22, thereby reducing the number of subsequent rework of the sole plate, improving the connection efficiency between the short column 1 and the steel column, and reducing the economic losses caused by rework.

[0027] Preferably, the pull rope 7 is an elastic rope, so that the pull rope 7 can be relatively deformed, which is convenient for subsequent movement of the slider 6, adjustment of the position of the slider 6, and thus change of the size and position of the anchor placement area 8 to meet the needs of different models of anchor bolts 22.

[0028] Preferably, Figure 5 and Figure 6 As shown, the slider 6 on one side is provided with a through hole for the pull rope 7 to pass through, and the slider 6 is provided with a plurality of elastic blocks 9 and a locking block 10 threadedly connected. The end of the elastic block 9 is provided with a first inclined surface 11, and one side of the locking block 10 is provided with a second inclined surface 12 in contact with the first inclined surface 11. One side of the elastic block 9 is in contact with the pull rope 7. After adjusting the position of the slider 6, the friction between the slider 6 and the frame 2 is increased by tightening the pull rope 7, and the slider 6 is fixed to the frame 2. Then, the locking block 10 is rotated on the slider 6, and the second inclined surface 12 of the locking block 10 is in contact with the first inclined surface 11 on the elastic block 9. After the first inclined surface 11 contacts, the component force generated drives the elastic block 9 to deform until the elastic block 9 contacts the pull rope 7. The friction force generated after the contact limits the movement of the pull rope 7 relative to the elastic block 9, thereby achieving the fixation of the anti-collision inspection device, avoiding the external force from accidentally driving the slider 6 to move, affecting the size and position of the anchor placement area 8, and avoiding the longitudinal reinforcement 3 and stirrups 4 after the construction is completed from interfering with the theoretical position of the anchor bolt 22. There is no need to move the position of the anchor bolt 22, thereby reducing the number of subsequent rework of the sole plate, improving the connection efficiency of the short column 1 and the steel column, and reducing the economic losses caused by rework.

[0029] Preferably, Figure 6 As shown, the end of the slider 6 is provided with a friction portion 13 in contact with the frame 2, which increases the friction between the slider 6 and the frame 2, avoids the external force from inadvertently changing the position of the slider 6, affecting the size and position of the anchor placement area 8, and avoids the longitudinal reinforcement 3 and stirrups 4 after the construction is completed from interfering with the theoretical position of the anchor bolt 22. There is no need to move the position of the anchor bolt 22, thereby reducing the number of subsequent rework of the sole plate, improving the connection efficiency of the short column 1 and the steel column, and reducing the economic losses caused by rework.

[0030] Preferably, Figure 7 As shown, the frame 2 is provided with a plurality of grooves 14 connected with the slide groove 5, and the slider 6 is provided with a ball 15 in contact with the groove 14, and a spring 16 is provided between the two balls 15. When the position of the slider 6 needs to be adjusted, a force greater than the rebound force of the spring 16 after compression is applied to push the slider 6 to slide on the frame 2. The side of the ball 15 contacts the through-hole, and the component force generated pushes the ball 15 to move inward, so that the slider 6 slides on the frame 2 until the ball 15 moves to the next groove 14. The rebound force generated by the compression of the spring 16 drives the ball 15 to reset and enter the next groove 14. Repeat the above steps to adjust the position of the slider 6, thereby changing the size and position of the anchor placement area 8 to meet the needs of different models of anchor bolts 22.

[0031] Preferably, Figure 7As shown, the slider 6 is symmetrically provided with a wedge block 17, one side of the wedge block 17 is provided with an arc groove 18 in contact with the ball 15, the spring 16 is provided between the two wedge blocks 17, the slider 6 is threadedly connected with a screw 19, and the screw 19 is provided with a conical surface 20 in contact with the wedge block 17. After adjusting the position of the slider 6, the screw 19 is rotated on the slider 6 to move the screw 19 on the slider 6 until the conical surface 20 provided at the end of the screw 19 contacts the wedge block 17. The force generated drives the two wedge blocks 17 to move inward at the same time, and at the same time, The arc groove 18 provided at the end of the wedge block 17 contacts the ball 15, and the resistance generated limits the movement of the ball 15 inward. The resistance generated by the contact between the ball 15 and the groove 14 limits the movement of the slider 6 relative to the frame 2, thereby preventing external forces from inadvertently changing the position of the slider 6 and affecting the size and position of the anchor placement area 8, and avoiding interference between the longitudinal reinforcement 3 and the stirrups 4 after construction is completed and the theoretical position of the anchor bolt 22. There is no need to move the position of the anchor bolt 22, thereby reducing the number of subsequent rework of the sole plate, improving the connection efficiency between the short column 1 and the steel column, and reducing the economic losses caused by rework.

[0032] Preferably, Figure 2 and Figure 4 As shown, the frame 2 is welded by eight flat steels alternately arranged up and down, and the slide 5 is located between the upper and lower adjacent flat steels. The frame 2 can be welded by using the scraps left at the site, further reducing the cost required for manufacturing the frame 2.

[0033] Preferably, Figure 2 and Figure 4 As shown, the flat steel on the upper side is provided with scale lines 21, which facilitates measuring the distance moved by the slider 6 on the frame 2 and improves the detection accuracy of the anti-collision inspection device.

[0034] Example 1

[0035] The utility model provides an anti-collision inspection device for exposed column foot anchor bolts and short column stirrups, such as Figure 2 、 Figure 3 and Figure 4 As shown, by sliding the slider 6 on the frame 2, the corresponding pull rope 7 is driven to move on the frame 2, and the intersection of the corresponding pull rope 7 and the other pull ropes 7 is changed to form an anchor placement area 8. The above steps are repeated to make each anchor placement area 8 correspond to the theoretical position of the anchor bolts 22 with different outer diameters. This can meet the needs of different models of anchor bolts 22, and there is no need to separately manufacture anti-collision inspection devices of different specifications, thereby reducing the cost required for manufacturing the anti-collision inspection device.

[0036] Then place the frame 2 on the foundation surface of the short column 1, and clearly identify the area that will interfere with the anchor bolts 22. During the subsequent construction of the longitudinal reinforcement 3 and the stirrups 4, avoid the anchor placement area 8 to prevent the longitudinal reinforcement 3 and the stirrups 4 from interfering with the theoretical position of the anchor bolts 22 after the construction is completed. There is no need to move the position of the anchor bolts 22, thereby reducing the number of subsequent rework of the sole plate, improving the connection efficiency between the short column 1 and the steel column, and reducing the economic losses caused by rework.

[0037] Example 2

[0038] Based on Example 1, Figure 5 and Figure 6 As shown, after adjusting the position of the slider 6, the pull rope 7 is tightened so that the friction part 13 provided on the slider 6 contacts the frame 2, increasing the friction force between the slider 6 and the frame 2, and fixing the slider 6 on the frame 2. Then, the locking block 10 is rotated on the slider 6, and the second inclined surface 12 of the locking block 10 contacts the first inclined surface 11 provided on the elastic block 9, and the component force generated drives the elastic block 9 to deform until the elastic block 9 contacts the pull rope 7. The friction force generated after the contact limits the movement of the pull rope 7 relative to the elastic block 9, thereby achieving the fixation of the anti-collision inspection device, avoiding the external force from accidentally driving the slider 6 to move, affecting the size and position of the anchor bolt placement area 8, and avoiding the longitudinal reinforcement 3 and stirrups 4 after the construction is completed from interfering with the theoretical position of the anchor bolt 22. There is no need to move the position of the anchor bolt 22, thereby reducing the number of subsequent rework of the foot plate, improving the connection efficiency of the short column 1 and the steel column, and reducing the economic loss caused by rework.

[0039] Example 3

[0040] Based on Example 1, Figure 7 As shown, when the position of the slider 6 needs to be adjusted, a force greater than the rebound force of the compressed spring 16 is applied to push the slider 6 to slide on the frame 2. The side of the ball 15 contacts the through hole, and the component force generated pushes the ball 15 to move inward, so that the slider 6 slides on the frame 2 until the ball 15 moves to the next groove 14. The rebound force generated by the compression of the spring 16 drives the ball 15 to return to the next groove 14. Repeat the above steps to adjust the position of the slider 6, thereby changing the size and position of the anchor placement area 8 to meet the needs of different types of anchor bolts 22.

[0041] After adjusting the position of the slider 6, the screw 19 is rotated on the slider 6 to make the screw 19 move on the slider 6 until the conical surface 20 provided at the end of the screw 19 contacts the wedge block 17. The force generated drives the two wedge blocks 17 to move inward at the same time. At the same time, the arc groove 18 provided at the end of the wedge block 17 contacts the ball 15, and the resistance generated limits the movement of the ball 15 inward. The resistance generated after the ball 15 contacts the groove 14 limits the movement of the slider 6 relative to the frame 2, avoiding the external force from inadvertently changing the position of the slider 6, affecting the size and position of the anchor bolt placement area 8, and avoiding the longitudinal reinforcement 3 and stirrups 4 after the construction is completed from interfering with the theoretical position of the anchor bolt 22. There is no need to move the position of the anchor bolt 22, thereby reducing the number of subsequent rework of the foot plate, improving the connection efficiency of the short column 1 and the steel column, and reducing the economic loss caused by rework.
