Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of building equipment, more specifically, relates to a type of steel column pre-buried anchor bolt installation auxiliary equipment and auxiliary installation method. BACKGROUND

[0002] In modern building structures, steel columns serve as one of the main load-bearing components, and their stability and safety are directly related to the reliability of the entire building. The fixation of steel columns usually relies on pre-buried anchor bolts installed in advance on the concrete foundation or ground. These anchor bolts, as important elements connecting the steel column and the foundation, not only bear the gravity load of the building, but also withstand external environmental actions such as wind and earthquakes. Therefore, the design and installation quality of steel column pre-buried anchor bolts are crucial to the safety of building structures. Pre-buried anchor bolts are usually composed of bolts and bases. During construction, the anchor bolts are pre-buried in the concrete so that the steel column can be fixed to the base in subsequent construction. The installation position, depth, and levelness of these anchor bolts directly determine the installation accuracy of the steel column. Therefore, in engineering practice, how to ensure the accurate installation of pre-buried anchor bolts and maintain their position stability during the curing process of concrete has become an important challenge in the construction process. With the continuous improvement of safety and construction quality requirements in modern architecture, the requirements for pre-buried anchor bolt installation technology are also becoming higher, which provides important background and technical driving force for the research of the present application.

[0003] The traditional method of installing steel column pre-buried anchor bolts usually includes the following steps: first, determine the position of the anchor bolts according to the design drawings, then connect multiple steel bars with these anchor bolts together to form a stable anchor bolt frame. Next, the entire frame is fixed on the base by pouring concrete. After the concrete solidifies, these anchor bolts become the foundation connecting pieces for the installation of steel columns. Through this method, anchor bolts can be pre-buried during construction to provide foundation support for subsequent steel column installation. However, in actual construction, this traditional method has some inherent shortcomings. During the curing and drying process of concrete, it often shrinks to some extent. Due to the unevenness of concrete shrinkage, the anchor bolts buried in it may experience slight displacement or deformation. Although this change may not be obvious on a single anchor bolt, when multiple anchor bolts work together, it can lead to a decrease in installation accuracy. This displacement or deformation often causes the hole position of the steel column to be unable to accurately align with the pre-buried anchor bolt during the subsequent connection of the steel column and the anchor bolt, thereby affecting the fixing effect of the steel column and even possibly causing structural safety hazards. In addition, due to the complex construction site environment and the uneven skill levels of operators, the traditional installation method has high technical requirements for construction personnel and is time-consuming and labor-intensive.

[0004] Aiming at the technical problems existing in the traditional steel column embedded anchor installation method, the application proposes a new type of auxiliary equipment and installation method, aiming to solve the problems of position deviation of embedded anchor and insufficient installation precision in traditional process. On the basis of in-depth analysis of existing technology, we found that the position change of anchor caused by concrete shrinkage is one of the main factors affecting the installation precision of steel column. Because the shrinkage of concrete is inevitable during the curing process, and this shrinkage is uneven, the anchor may move or deform during the curing process, and this subtle change will be amplified in the subsequent docking process of steel column and anchor, resulting in misalignment during installation. In addition, the traditional installation method lacks effective precision adjustment means, and after the anchor position changes slightly, the construction personnel often cannot remedy it through simple manual operation. This not only increases the installation difficulty, but also easily leads to rework, thereby affecting the construction progress and cost control. On the other hand, since the traditional method relies on the connection of multiple anchors and steel bars to maintain the integrity of the structure, in actual operation, this method has poor environmental adaptability on site, especially in complex terrain or irregular base, which easily leads to installation difficulties.

[0053] As Figures 1-12As shown, the embodiment of the present application provides a type of steel column pre-buried anchor installation auxiliary equipment, which realizes high-precision pre-buried anchor positioning and installation through a series of precise mechanical component combinations.

The pressing plate 20 is fixed on the square slide column 21 and its position is adjusted through the lead screw 22, the slide column is installed in the sliding sleeve 19, and the sliding sleeve is fixed on the square slide rod 6. The supporting structure is connected to the disc 1 through supporting bolts 26 to adjust the horizontal state of the equipment. The rotating ring 8 is rotated through the worm 18 to realize accurate adjustment of the position of the steel column pre-buried anchor 24, the limiting component ensures the stability of the rotating ring 8 during rotation, and finally the height and position of the anchor are accurately controlled through the cooperation of the pressing plate 20 and the sliding sleeve 19, so as to achieve the purpose of accurate installation. The equipment of the present application drives the rotating ring to rotate through the worm and the circular arc worm gear, the rotating ring drives the roller to move, since the gap on the shell is gradually filled by the rotating ring, the rotating ring drives the steel column pre-buried anchor to be pressed between the rotating ring and the shell through the roller, the rotating ring drives the lead screw to move through the circular arc rack and the circular ring gear, the lead screw drives the square slide column to move downward, the square slide column drives the pressing plate to move downward, and the pressing plate moves downward and abuts against the top end of the steel column pre-buried anchor. The device can limit the horizontal position and the length of the steel column pre-buried anchor, avoid the movement or deformation of the steel column pre-buried anchor caused by the shrinkage of concrete during the curing and drying process of concrete, ensure that the subsequent steel column pre-buried anchor can be correctly aligned with the hole position of the steel, and ensure the correct fixing of the subsequent steel.

[0054] Among them, the main body of the equipment is a disc 1, the upper surface of which is provided with a bubble level 2 for ensuring the horizontal state of the equipment during installation. The outer periphery of the disc 1 is provided with a ring groove, and four cylindrical blocks 3 are installed on the inner wall of the ring groove at equal intervals in the circumferential direction. Each cylindrical block 3 is fixedly provided with a sleeve 4, and the sleeve 4 slidably installs a square slide rod 6. One end of the square slide rod 6 is fixedly installed on a shell 7, and through this structural design, the equipment can flexibly adjust the position of the steel column pre-buried anchor to ensure that it is consistent with the design requirements. The equipment of the present application can adapt to different ground conditions of construction sites through the combination of the supporting structure and the bubble level, ensure that the equipment works in a horizontal state, and thus ensure the installation accuracy. In addition, the positioning holes of the cylindrical block and the disc are used in cooperation, so that the equipment has high stability during construction and is not easy to be displaced due to external force.

[0055] The inner part of the shell 7 is provided with a circular arc groove, and the inner wall of the circular arc groove is slidably installed with a rotating ring 8. The rotating ring 8 and the circular arc groove share a common center, which ensures the stability and accuracy of the rotating ring during rotation. The outer surface of the shell 7 is provided with a notch 11, and the outer surface of the rotating ring 8 is also provided with the same notch. A steel column pre-embedded anchor bolt 24 is arranged in the notch. By rotating the rotating ring 8, the position of the anchor bolt can be accurately adjusted to keep it at the horizontal position required by the design drawing.

[0056] In order to prevent unnecessary displacement of the rotating ring 8 during operation, a limiting component is arranged between the shell 7 and the rotating ring. The limiting component includes a limiting groove 10 opened on the upper and lower surfaces of the rotating ring, and the top wall and the bottom wall of the shell 7 are fixedly installed with limiting protrusions 9. The limiting protrusions 9 and the inner wall of the limiting groove 10 are in sliding fit, which ensures the stability of the rotating ring 8 during rotation, thereby ensuring the installation accuracy of the steel column pre-embedded anchor bolt 24.

[0057] The transmission structure of the device is composed of a worm 18 and a circular arc worm gear 14. The worm 18 penetrates through the outer surface of the shell 7 and is engaged with the circular arc worm gear 14 through the first opening 12. The circular arc worm gear 14 is fixedly installed on the outer periphery of the rotating ring 8. By rotating the worm 18, the operator can drive the rotating ring 8 to rotate, thereby realizing accurate positioning of the steel column pre-embedded anchor bolt 24. The two ends of the worm 18 penetrate through the outer surface of the support block 17 and are provided with hexagonal holes, which are convenient for operation with standard tools. The precise engagement of the worm 18 and the circular arc worm gear 14 ensures the transmission efficiency and positioning accuracy of the device, and improves the simplicity and controllability of the operation. Through the precise transmission design of the worm and the circular arc worm gear, the device realizes fine adjustment and accurate control of the position of the steel column pre-embedded anchor bolt. Through the cooperation of the limiting component and the pressing plate, the device can ensure that the position of the anchor bolt does not deviate or deform during the concrete pouring and curing process, thereby ensuring the perfect butt joint of the anchor bolt and the steel column hole, significantly improving the installation accuracy, significantly improving the construction efficiency, and reducing the complexity and error of human operation.

[0058] In the construction process, in order to ensure the height and position accuracy of the steel column pre-embedded anchor bolt 24, a sliding sleeve 19 is installed on the square slide rod 6. The square slide rod 6 is slidably installed in the sliding sleeve 19, and the top end of the slide rod is fixedly installed with a pressing plate 20. The pressing plate 20 is in contact with the top end of the anchor bolt 24 through its lower surface, and applies necessary pressure during the concrete pouring and curing process to prevent the anchor bolt from being displaced due to concrete shrinkage or external force. In order to accurately control the movement of the pressing plate 20, a lead screw 22 is also installed on the upper surface of the square slide rod 6. The lead screw 22 is arranged inside the sliding sleeve 19 and connected with the square slide rod 21 through threads, and the top is engaged with the circular arc rack 15 of the rotating ring 8 through a circular ring gear 23. By moving the lead screw 22, the position and height of the pressing plate 20 can be accurately adjusted to ensure that the installation depth of the steel column pre-embedded anchor bolt 24 meets the design requirements.

[0059] The overall stability of the device is ensured by the support structure. The bottom outer periphery of the disc 1 is equidistantly distributed with four support rods 25, the ends of which are installed with support bolts 26, the bottom ends of which are connected with support plates 27. The support bolts 26 are adjusted in height by threaded connection, so that the device can adapt to different construction site conditions, while ensuring that the device always remains stable during operation.

[0060] In addition, in order to further fix the position of the square slide rod 6, the upper surface of the sleeve 4 is provided with an internal hexagonal compression bolt 5. The internal hexagonal compression bolt 5 is threadedly connected with the sleeve 4, and the bottom end of the bolt abuts against the outer surface of the square slide rod 6. By rotating the internal hexagonal compression bolt 5, the square slide rod 6 can be locked in place, avoiding accidental movement of the slide rod during operation. This design ensures the stability of the device during operation, especially in the case of frequent position adjustment, it can maintain high-precision anchor positioning.

[0061] In actual operation, the installation and adjustment process of the device is completed through various positioning components. The upper surface of the cylindrical block 3 is provided with a plurality of equidistantly arranged first positioning holes 29, and the upper surface of the disc 1 is provided with four second positioning holes 30. By inserting the T-shaped pin 28, the parts of the device can be quickly and accurately fixed at the predetermined position, ensuring the stability and accuracy of the entire device. This design simplifies the installation and disassembly process of the device, improving the construction efficiency.

[0062] As shown in Figure 13 In another embodiment of the present application, a method for auxiliary installation of pre-buried anchors based on shaped steel columns is provided. This method ensures high precision and stability of the pre-buried anchors during installation through a step-by-step operation process, avoiding the displacement or deformation of the anchors due to human error or external forces during construction. The specific operation steps are as follows.

[0063] Step 1: Initial installation and horizontal calibration of the device

[0064] First, place the disc 1 of the device on the predetermined construction site. When placing the device, ensure that the approximate position of the disc meets the requirements of the construction drawings. Use the bubble level 2 provided with the device to calibrate the device horizontally. Adjust the support bolts 26 at the bottom of the disc 1 so that the bubble level shows that the device has reached a completely horizontal state. At this time, the support rods 25 of the device should be evenly distributed, and the support plates 27 should be firmly in contact with the ground to ensure the overall stability of the device. After horizontal calibration, the operator should check again whether the support bolts and support plates are firm to ensure that the device will not sway or shift due to uneven ground or external forces during subsequent operations.

[0065] Step 2: Precise positioning and fixing of the device

[0066] After the initial installation of the device is completed, according to the anchor bolt position required by the construction drawing, adjust the cylindrical block 3 on the disc 1 to the correct position. The operator matches the first positioning hole 29 on the cylindrical block 3 with the second positioning hole 30 on the disc 1, inserts the T-shaped bolt 28, and firmly fixes the cylindrical block 3 on the outer periphery of the disc 1. Next, adjust the square slide rod 6 in the sleeve 4, and ensure the flexibility of the device by adjusting the position of the square slide rod and fixing it with the shell 7. Rotate the inner hexagonal compression bolt 5 to lock the position of the square slide rod 6 to prevent position movement during subsequent construction.

[0067] Step 3: Initial positioning of the embedded anchor bolt

[0068] After the initial position of the device is fixed, place the steel column embedded anchor bolt 24 in the gap 11 of the rotating ring 8. At this time, the initial position of the anchor bolt should generally meet the design requirements, but it does not need to be completely accurate, because the subsequent steps of the device will further adjust the position of the anchor bolt. Rotate the worm 18 to drive the rotation of the circular worm gear 14, thereby driving the rotation of the rotating ring 8. Adjust the position of the steel column embedded anchor bolt 24 to be consistent with the design requirement horizontal position by rotating the rotating ring 8. During the adjustment process, the operator should constantly check the position of the anchor bolt to ensure its accuracy on the horizontal plane.

[0069] Step 4: Fine adjustment of the anchor bolt position

[0070] After the initial positioning of the embedded anchor bolt 24 is completed, further fine adjustment of the position of the anchor bolt is carried out using the combination structure of the sliding sleeve 19 and the square slide column 21. Adjust the pressure plate 20 to be in close contact with the top end of the steel column embedded anchor bolt 24 by adjusting the lead screw 22 to apply appropriate pressure. During the adjustment process, the rotating ring 8 drives the lead screw 22 to move through the circular arc rack 15 and the circular ring gear 23, and the position of the pressure plate 20 is fine adjusted to ensure that the height and horizontal position of the anchor bolt completely meet the design requirements. The pressure adjustment of the pressure plate 20 is very critical, and when the pressure is applied, it should ensure enough force to fix the anchor bolt, but it should not be too large to cause deformation or damage to the anchor bolt. The operator should flexibly adjust the size of the applied pressure according to the specific situation of the construction site.

[0071] Step 5: Final fixing of the anchor bolt and device inspection

[0072] After ensuring that the position and height of the anchor bolt 24 fully meet the design requirements, the operator should again check the fixing of each part of the device, especially whether the locking of the square slide bar 6, the worm 18, the sliding sleeve 19, and the pressing plate 20 is stable, to ensure that the device will not be displaced during the concrete pouring process. At this time, the operator can proceed with the concrete pouring work. During the concrete pouring process, the device will continue to maintain the position of the anchor bolt, ensuring that it does not displace or deform during the concrete curing period.

[0073] Step 6: Device disassembly and construction completion

[0074] After the concrete has fully cured, the operator can begin disassembling the device. First, loosen the inner hexagonal compression bolt 5 to unlock the fixing of the square slide bar 6, then sequentially disassemble the T-shaped latch 28 and remove the cylindrical block 3 and the anchor bolt installed thereon. During the device disassembly process, care should be taken to avoid any impact or vibration on the already cured concrete and anchor bolt, so as not to affect the final installation quality. All device components should be disassembled in order and properly stored for subsequent reuse.

[0075] Step 7: Installation of subsequent steel column

[0076] After the device is disassembled, the steel column pre-buried anchor bolt 24 should remain in the accurate predetermined position and height, and the operator can proceed with the subsequent steel column installation work.
