Description

Technical Field

[0001] This utility model relates to the field of equipment installation technology, and in particular to an installation and positioning device for foundation anchor bolts of large equipment. Background Technology

[0002] In the installation of large industrial equipment, the positioning accuracy of the anchor bolts in the equipment foundation directly affects the subsequent installation quality and operational stability of the equipment. In traditional equipment foundation construction processes, anchor bolts are fixed to the steel reinforcement cage of the equipment foundation by tying wire or welding. The overall integrity of the steel reinforcement cage restricts the displacement of the anchor bolts and prevents them from shaking during construction. This fixing method is suitable for small equipment foundations where the concrete volume and depth are small, so it does not affect the anchor bolts fixed to the steel reinforcement cage. However, in the construction of large equipment foundations, the concrete volume is large, usually reaching hundreds of cubic meters, and the pouring time is long. The lateral impact force generated by pumping concrete is large. Under the action of continuous dynamic load, the steel reinforcement is prone to displacement, causing the anchor bolts to move, which makes it impossible to accurately install large industrial equipment later. In addition, in order to ensure the stability of large equipment foundations, the pouring depth is deep, usually exceeding 50cm. During the pouring process, construction workers will stand above or around the foundation and use vibrators to ensure the compactness of the poured concrete and avoid defects such as honeycomb and pitting. However, the long-term standing of personnel will cause local stress concentration in the steel reinforcement cage, leading to wire breakage or weld cracking, which in turn causes the anchor bolts to move. This makes it impossible to guarantee the installation accuracy of the anchor bolts, which will have a great impact on the subsequent installation of equipment and may even lead to the redoing of the foundation. Furthermore, the existing technology only connects the anchor bolts to the steel reinforcement cage, which cannot guarantee the verticality accuracy of the anchor bolts for equipment foundations with deep pouring depth. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an installation and positioning device for anchor bolts of large equipment foundations. It is mainly used for positioning and installing anchor bolts of large equipment foundations to fix the position of the anchor bolts of large equipment foundations, avoid displacement during concrete pouring, and ensure the three-dimensional installation accuracy of the anchor bolts before and after concrete pouring, so as to facilitate the installation of large equipment.

[0004] This utility model discloses an installation and positioning device for anchor bolts of large equipment foundations, including an installation bracket set around the perimeter of the equipment foundation. The installation bracket includes concrete foundations set on the outer sides of the four corners of the equipment foundation. Each concrete foundation has a vertically installed steel column. A first connecting rod is provided between two adjacent steel columns along the length of the equipment foundation. A second connecting rod is provided below the first connecting rod along the width of the equipment foundation. A bracket for connecting each second connecting rod to the first connecting rod is provided. The bracket includes a first channel steel, a second channel steel, and a double-ended threaded rod. The first channel steel is parallel to the second connecting rod and is set above the first connecting rod. The second channel steel is parallel to the first connecting rod and is set below the second connecting rod. At least two parallel double-ended threaded rods pass through the first channel steel, the first connecting rod, the second connecting rod, and the second channel steel in sequence. One end of the double-ended threaded rod has a first bolt for fixing the first channel steel and the first connecting rod. The other end of the double-ended threaded rod has a second bolt for fixing the second channel steel and the second connecting rod. The second connecting rod has a positioning hole for the anchor bolt to pass through.

[0005] Furthermore, the bracket also includes a connecting steel plate, which is disposed between two adjacent first channel steels and fixedly connected to the first channel steels.

[0006] Furthermore, the bracket further includes a reinforcing column, which is arranged parallel to the double-ended screw and between two adjacent double-ended screws. One end of the reinforcing column abuts against the lower end of the first connecting rod, and the other end abuts against the upper end of the second connecting rod.

[0007] Furthermore, a reinforcing link is provided between the two parallel first links, and the two ends of the reinforcing link are fixedly connected to the first links.

[0008] As a preferred embodiment, at least two of the reinforcing rods are evenly distributed along the length of the connecting rod.

[0009] Furthermore, the steel column is also connected to a diagonal brace, one end of which is welded to the steel column and the other end is connected to a ground anchor set on the ground.

[0010] Furthermore, the first connecting rod is also provided with a lifting beam for fixing the steel embedded part. The lower end of the lifting beam is provided with an angle steel, and two through holes are opened on the angle steel. A vertically arranged adjusting screw is inserted into each through hole. The bottom end of the adjusting screw is welded to the top of the steel embedded part. A lower wing plate is also connected between the lower ends of two adjacent adjusting screws. The bottom of the lower wing plate is welded to the steel embedded part.

[0011] The beneficial effects of this utility model are: it utilizes an installation bracket that does not contact the poured concrete to provide the installation and fixing points for the anchor bolts, ensuring that the anchor bolts do not contact the reinforcing steel bars of the equipment foundation; and it achieves three-dimensional precise positioning of the anchor bolts by using a first connecting rod arranged along the length of the equipment foundation, a second connecting rod arranged along the width of the equipment foundation, and a bracket for connecting the first and second connecting rods; and the anchor bolts will not shift due to the impact of the concrete during pouring, ensuring the precise positioning and installation of the anchor bolts for the installation of large equipment.

Detailed Implementation

[0020] The present invention will be further described below.

[0021] This utility model provides an installation and positioning device for anchor bolts of large equipment foundations, mainly used for positioning and installing anchor bolts of large equipment foundations. It includes an installation bracket 2 arranged around the perimeter of the equipment foundation 1. The installation bracket 2 includes concrete foundations 21 arranged on the outer sides of the four corners of the equipment foundation 1. Each concrete foundation 21 has a vertically mounted steel column 22. A first connecting rod 31 is arranged along the length of the equipment foundation 1 between two adjacent steel columns 22. A second connecting rod 32 is arranged along the width of the equipment foundation 1 below the first connecting rod 31. A bracket 4 for connection is provided between each second connecting rod 32 and the first connecting rod 31. The bracket 4 includes a first channel steel 41. The second channel steel 42 and the double-ended lead screw 43; the first channel steel 41 is parallel to the second connecting rod 32 and is positioned above the first connecting rod 31, and the second channel steel 42 is parallel to the first connecting rod 31 and is positioned below the second connecting rod 32. At least two parallel double-ended lead screws 43 pass through the first channel steel 41, the first connecting rod 31, the second connecting rod 32, and the second channel steel 42 in sequence. One end of the double-ended lead screw 43 is provided with a first bolt 431 for fixing the first channel steel 41 and the first connecting rod 31, and the other end of the double-ended lead screw 43 is provided with a second bolt 432 for fixing the second channel steel 42 and the second connecting rod 32. The second connecting rod 32 is provided with a positioning hole 321 for the anchor bolt 5 to pass through.

[0022] The installation and positioning device for the foundation anchor bolts of this large equipment includes a mounting bracket 2, such as... Figure 1 , Figure 2 As shown, the mounting bracket 2 includes concrete foundations 21 located on the outer sides of the four corners of the equipment foundation 1, avoiding the main structure of the equipment foundation 1 to prevent interference with subsequent construction of the equipment foundation 1. The concrete foundations 21 are 600mm × 600mm × 400mm in size and are cast using C20 cement. Each concrete foundation 21 is vertically supported by a steel column 22, the base of which is fixed to the top surface of the concrete foundation 21 by expansion bolts 211. Figures 1-5As shown, a first connecting rod 31 is provided between two adjacent steel columns 22, arranged along the length of the equipment foundation 1. Each first connecting rod 31 is fixed to the steel column 22 with 16 M16*50 mounting bolts. Below the first connecting rod 31, a second connecting rod 32 is provided through a bracket 4, arranged along the width of the equipment foundation 1. The first connecting rod 31 arranged along the length of the equipment foundation 1 and the second connecting rod 32 arranged along the width of the equipment foundation 1 form an orthogonal positioning system above the equipment foundation 1. The setting position of the second connecting rod 32 is set according to the installation point of the anchor bolt 5 to ensure the positioning and installation of the anchor bolt 5. The aforementioned first connecting rod 31 and second connecting rod 32 can be made of existing steel The beam facilitates connection and saves costs. A bracket 4 connects the first link 31 and the second link 32, creating a gap between them. This allows the upper end of the anchor bolt 5 to pass through the second link 32 for fixation, achieving three-dimensional positioning of the anchor bolt 5. The first link 31 determines the installation point of the anchor bolt 5 along the length of the equipment foundation 1, and the second link 32 determines the installation point of the anchor bolt 5 along the width of the equipment foundation 1. A double-ended threaded rod 43 then fixes the second link 32 below the first link 31, ensuring horizontal installation of the second link 32 and preventing tilting. Tilts in the second link 32 would cause the anchor bolt 5 to tilt or shift, affecting subsequent installation. Precision; A first channel steel 41 is provided above the first connecting rod 31 for positioning and installation of the double-ended bolt. The two-point positioning installation of the first channel steel 41 and the first connecting rod 31 fixes the installation position of the upper end of the double-ended bolt and reduces friction between the double-ended bolt and the first connecting rod 31, preventing connection instability during use; A second channel steel 42 is provided below the second connecting rod 32 for positioning and installation of the double-ended bolt. The two-point positioning installation of the second channel steel 42 and the second connecting rod 32 fixes the installation position of the lower end of the double-ended bolt and reduces friction between the double-ended bolt and the second connecting rod 32, preventing connection instability during use; A positioning hole 321 is provided on the second connecting rod 32 for the anchor bolt 5 to pass through. The opening of the positioning hole 321... The spacing of the anchor bolts 5 can be set to ensure the accuracy of the installation points of the anchor bolts 5. The upper end of the anchor bolt 5 passes through the positioning hole 321 and is vertically set on the second connecting rod 32 by the connecting bolt 54. The mounting bracket 2, which does not contact the poured concrete, provides the installation fixing point of the anchor bolt 5, so that the anchor bolt 5 does not contact the steel reinforcement of the equipment foundation 1. The anchor bolt 5 is also fitted with a rubber sleeve 51 to increase the bonding force between the bolt and the concrete. The three-dimensional precise positioning of the anchor bolt 5 is achieved by using the first connecting rod 31 arranged along the length direction of the equipment foundation 1, the second connecting rod 32 arranged along the width direction of the equipment foundation 1, and the bracket 4 used to connect the first connecting rod 31 and the second connecting rod 32.Furthermore, the anchor bolts 5 will not shift due to the impact of the concrete during pouring, ensuring precise positioning and installation of the anchor bolts 5 for the installation of large equipment.

[0023] To ensure the stability of the double-ended screw 43 during construction, such as Figures 3-5 As shown, the bracket 4 also includes a connecting steel plate 44, which is disposed between two adjacent first channel steels 41 and fixedly connected to the first channel steels 41. By setting the connecting steel plate 44 between adjacent first channel steels 41, the adjacent first channel steels 41 form an integral structure, so that the two double-ended threaded rods 43 that pass through the first channel steel 41, the first connecting rod 31, and the second connecting rod 32 in sequence form a stable frame structure with the first channel steel 41, which is not prone to deformation. This ensures that the position of the bracket 4 installed on the first connecting rod 31 does not change during use, thereby fixing the installation point of the anchor bolts 5 connected to the bracket 4, ensuring the installation accuracy of the anchor bolts 5, and avoiding large positioning errors caused by the anchor bolts 5 shifting during subsequent concrete pouring. To ensure the connection stability between the first connecting rod 31 and the second connecting rod 32, as well as the stability of the bracket 4 during use, such as Figure 3 , Figure 4 As shown, the bracket 4 also includes a reinforcing column 45, which is parallel to the double-ended screw rod 43 and positioned between two adjacent double-ended screw rods 43. One end of the reinforcing column 45 abuts against the lower end of the first connecting rod 31, and the other end abuts against the upper end of the second connecting rod 32. The reinforcing column 45, which abuts against the first connecting rod 31 and the second connecting rod 32, ensures that the second connecting rod 32 will not shift during use, thereby ensuring the stability of the anchor bolt 5 connected to the second connecting rod 32 and ensuring the perpendicularity of the anchor bolt 5 connected to the second connecting rod 32. This ensures that the anchor bolt 5 remains stable even when subjected to the impact force of concrete during concrete pouring, thus ensuring the installation accuracy of the anchor bolt 5.

[0024] To enhance the stability of the first link 31 and ensure that it does not tilt or bend during use, such as... Figure 2 As shown, a reinforcing link 311 is also provided between the two parallel first links 31, and the two ends of the reinforcing link 311 are fixedly connected to the first links 31. By providing a reinforcing link 311 between the two parallel first links 31, a spatial truss structure is formed between the first links 31, the reinforcing link 311 and the steel column 22 to ensure the stability of the first links 31, so that the first links 31 will not deform or displace during use. Furthermore, to ensure the connection stability between adjacent first links 31, at least two reinforcing links 311 are evenly distributed along the length direction of the connecting rod. The addition of reinforcing links 311 ensures that the stability between the first links 31 is strengthened.

[0025] To ensure the stability of steel column 22, such as Figure 1 As shown, the steel column 22 is also connected to a diagonal brace 23. A transverse steel pipe 221 is welded to the side of the steel column 22. One end of the diagonal brace 23 is connected to the transverse steel pipe 221, and the other end is connected to a ground anchor 24 set on the ground. A short steel pipe is welded to the outside of each steel column 22 as a transverse steel pipe 221, and a ground anchor 24 is driven into the ground in advance. Then, the two ends of the diagonal brace 23 are connected to the transverse steel pipe 221 and the ground anchor 24 respectively using steel pipe joints. The verticality of the steel column 22 is adjusted by adjusting the length of the diagonal brace 23. At the same time, the diagonal brace 23, the ground and the steel column 22 form a triangular stable system to ensure the stability of the steel column 22 and prevent it from shifting.

[0026] As a preferred method, the installation and positioning device for the foundation anchor bolts of this large equipment can also be used to fix the steel embedded parts 7, such as... Figure 6 , Figure 7 As shown, the first connecting rod 31 is also provided with a lifting beam 6 for fixing the steel embedded part 7. The lower end of the lifting beam 6 is provided with an angle steel 61. The angle steel 61 has two through holes 62. Each through hole 62 is provided with a vertically arranged adjusting screw 71. The bottom end of the adjusting screw 71 is welded to the top of the steel embedded part 7. A lower wing plate 63 is also connected between the lower ends of two adjacent adjusting screws 71. The bottom of the lower wing plate 63 is welded to the steel embedded part 7. Angle steel 61 is used to fix steel embedded part 7. Two adjusting screws 71 are welded to the top of steel embedded part 7. During welding, the verticality of adjusting screws 71 is ensured so that when adjusting screws 71 are passed through through hole 62, the verticality of steel embedded part 7 connected to adjusting screws 71 can be guaranteed. By welding lifting beam 6 to the top of first connecting rod 31, angle steel 61 to the bottom of lifting beam 6, adjusting screws 71 to the top of steel embedded part 7, and adjusting screws 71 passing through through hole 62 opened on angle steel 61, steel embedded part 7 can be vertically set by adjusting screws 71. In order to facilitate the calibration of the verticality of adjusting screws 71 connected to angle steel 61, a lower flange 63 is also connected between the lower ends of two adjacent adjusting screws 71, and steel embedded part 7 is welded to lower flange 63. During the measurement and layout, the installation axis of the adjusting screw 71 is aligned with the first connecting rod 31 and the lifting beam 6. After the short channel steel 65 is accurately positioned, it is welded and fixed. Then, two through holes 62 adapted to the adjusting screw 71 are opened on the angle steel 61 set at the lower end of the lifting beam 6. The adjusting screw 71 passes through the through holes 62 and connects with the lifting beam 6. The steel embedded part 7 is then welded and fixed to the lower flange 63 set between the adjusting screws 71, thereby ensuring the installation and positioning of the steel embedded part 7.
