Description

Technical Field

[0001] This utility model relates to the field of steel column base positioning technology, specifically to a steel column base positioning and adjustment device. Background Technology

[0002] Originating in the 20th century, steel-structured housing has become a new architectural trend in the 21st century due to its unique advantages. Compared to traditional concrete and wood structures, steel, as the primary material, combines high strength with excellent seismic performance, allowing for the creation of large-span, open spaces. The lightweight nature of steel not only reduces foundation load but also accelerates construction and shortens the construction period. Furthermore, steel is recyclable, aligning with sustainable development principles, and its design allows for greater flexibility, adapting to the diverse needs of modern architecture.

[0003] Steel structure buildings require extremely high installation precision. Even slight deviations in the dimensions, alignment, or elevation of components can lead to uneven stress or deformation of the structure. The installation of the steel column bases is a critical challenge, as their positioning and fixing accuracy directly affects the building's stability. Inaccurate alignment can easily cause stress imbalances and structural tilting. Currently, the elevation is generally controlled by rotating the adjusting nuts at the bottom of the column base. However, this method is limited by the weight of the steel column and the insertion of the base, resulting in labor-intensive and time-consuming processes. While jacks can be used to support the steel column base plate for adjustment, in practical applications, the large size of the jacks makes them unsuitable for small adjustment gaps, necessitating adjustment of the elevation by rotating the adjusting nuts at the bottom of the column base. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] The following is combined with Figures 1 to 3 The following describes embodiments of the present invention.

[0027] According to an embodiment of the present invention, a steel column base positioning and adjustment device is provided, comprising:

[0028] Support member 1, which includes a support part 11 and a lifting part 12, the support part 11 and the lifting part 12 are connected; the support part 11 is adapted to be disposed on the lower side of the steel column base plate 41, and at least a portion of the steel column base plate 41 abuts against the support part 11; the lifting part 12 extends upward in the vertical direction by a predetermined distance and is located on one side of the steel column 4.

[0029] Adjusting component 2 is located on the lower side of the lifting part 12. Adjusting component 2 is adapted to lift the lifting part 12 under the action of driving force so as to realize the height adjustment of the steel column base plate 41 in the vertical direction.

[0030] It is easy to understand that the lifting part 12 is set higher than the support part 11 in the vertical direction, which can provide more operating space for the adjusting part 2. Even when the adjustment gap between the steel column base plate 41 and the foundation surface is small, the adjusting part 2 can be installed smoothly and the height can be adjusted, avoiding the problem of difficulty or inability to adjust due to insufficient space. At the same time, this structural design makes the support part 11 and the steel column base plate 41 have a larger contact area, enhancing the stability of the support. In addition, the protruding lifting part 12 facilitates the precise application of force by the adjusting part 2, improving the accuracy and efficiency of the height adjustment of the steel column base plate 41.

[0031] Before constructing the steel column bases, the foundation must be poured first. According to design requirements, accurately reserve the installation positions and positioning bolt holes for steel column 4, ensuring the flatness and levelness of the foundation meet specifications, providing stable support for the subsequent installation of steel column 4. The fabricated steel column bases at the bottom are then hoisted to the foundation and connected to it via column base bolts 51.

[0032] It should be noted that the steel column base plate 41 is generally a rectangular or circular steel plate. Its dimensions need to be determined based on the cross-sectional size of the steel column 4, load transfer requirements, and the bearing capacity of the foundation. It is usually slightly larger than the cross-section of the steel column 4 to increase the contact area with the foundation. The steel column base plate 41 can evenly transfer the upper loads borne by the steel column 4, such as vertical pressure, horizontal shear force, and bending moment, to the foundation, preventing excessive local stress and subsequent damage. Simultaneously, it can be fixed to the foundation via anchor bolts, ensuring the stability and positioning accuracy of the steel column 4 during installation, providing a reliable benchmark for subsequent steel structure installation.

[0033] Specifically, the steel column base plate 41 is made of steel plate with a thickness of not less than 15mm. After the steel column base plate 41 is installed, it is welded to the reinforcing steel in the foundation structure. The pre-embedded positioning parts are completed during the pouring of the foundation concrete. It should be noted that the top surface of the steel column base plate 41 should be on the same horizontal plane, and the elevation and planar position accuracy of the positioning parts must meet the requirements of the specifications.

[0034] It should be noted that the steel column base plate 41 is provided with positioning screw holes. After the steel column base plate 41 is processed and fabricated, it is welded to the bottom end of the steel structure column body using special welding equipment. During installation, the steel column base plate 41 is first initially connected to the column foot screw 51 on the foundation. Then, the elevation and verticality of the base plate are adjusted by the column foot positioning and adjustment device. Finally, high-strength grouting material is used for secondary grouting to ensure that the steel column base plate 41 is tightly integrated with the foundation, forming a stable overall structure, thereby ensuring the safety and reliability of the steel structure building.

[0035] Specifically, in this embodiment, the steel column base plate 41 is made of rectangular steel plate, and positioning screw holes are reserved at all four corners, which are symmetrically arranged on both sides of the longitudinal and transverse axes of the horizontal section of the steel column 4 body.

[0036] It should be noted that the column base bolt 51 is preferably made of a Class A or Class B fully threaded hexagonal head bolt, with a bolt length of 650mm-750mm and a bolt diameter of not less than 20mm. The top of the bolt is a hexagonal head nut, and the bottom of the bolt is equipped with a bent or welded 20mm*80mm*80mm steel plate, which is welded and ground flat with the bolt.

[0037] Specifically, the inner wall of the positioning screw hole adopts a threaded structure, and the inner diameter, thread and pitch of the screw hole are matched with the column base screw 51; the positioning screw hole adopts the same specifications and dimensions, and the inner diameter matches the positioning screw.

[0038] Specifically, the column base screw 51 is fitted with a backstop nut 52, a fastening nut 53, a nut washer 55 and an adjusting nut 54 in sequence from high to low along the vertical direction.

[0039] The adjusting nut 54 is located at the bottom and is used to support the base plate 41 of the steel column 4 during installation. After the column foot positioning and adjusting device is used to adjust it to the appropriate position, the adjusting nut 54 is rotated to achieve support.

[0040] The nut washer 55 is a steel plate with a certain thickness and area, placed above the steel column base plate 41. It increases the contact area between the fastening nut 53 and the steel column base plate 41, allowing the pressure applied by the fastening nut 53 to be transmitted more evenly to the steel column base plate 41, preventing deformation or damage to the steel column base plate 41 due to excessive local pressure. Simultaneously, the nut washer 55 also provides a certain buffering effect, reducing wear between the fastening nut 53 and the steel column base plate 41.

[0041] The fastening nut 53 is positioned above the nut washer 55. After the steel column 4 is installed and adjusted to the correct position, tightening the fastening nut 53 connects the column base bolt 51 to the steel column base plate 41, ensuring that the column base will not loosen due to external forces during use. The fastening nut 53 provides the main connection and fastening force, ensuring a reliable connection between the steel column 4 and the foundation, and is able to withstand various loads transmitted by the steel structure.

[0042] The anti-loosening nut 52 is located at the top and is used to prevent the fastening nut 53 from loosening due to external forces such as vibration and impact during long-term use. Through special structural design, such as using a double nut structure or having an anti-loosening device, the anti-loosening nut 52 can effectively prevent the nut from rotating, improving the safety and reliability of the column base connection.

[0043] The steel column base positioning and adjustment device provided in this embodiment divides the support member 1 into a support part 11 and a lifting part 12. The support part 11 abuts against the steel column base plate 41, and the adjustment member 2 is set on the lower side of the lifting part 12. Under the action of driving force, the support member 1 is lifted to realize the vertical height adjustment of the steel column base plate 41. This avoids the situation where the jack cannot be placed in a small gap due to its large size. At the same time, it eliminates the need to adjust the bottom nut of the column base under the weight of the steel column 4, reducing the difficulty of manual operation and improving the convenience and accuracy of the installation of the steel column base 4.

[0044] Furthermore, it extends toward the side away from the steel column 4 to form a placement space for the adjustment element 2.

[0045] In a straightforward manner, the support component 1 extends towards the side furthest from the steel column 4 to form a space for the adjustment component 2. Because the adjustment component 2 (like a jack) is relatively large, this extension design effectively avoids the problem of insufficient space preventing its installation, ensuring that the adjustment component 2 can be smoothly placed and function during the positioning and adjustment of the steel column 4. Simultaneously, the specially formed placement space makes the relative positions of the adjustment component 2, support component 1, and steel column 4 more stable, allowing for precise force application during adjustment and preventing adjustment deviations caused by the displacement of the adjustment component 2. This improves the accuracy and efficiency of adjusting the height of the steel column 4's base plate, reduces construction risks due to inconvenient installation, and ensures safe and orderly construction.

[0046] Furthermore, a buffer layer is provided on the contact surface between the support part 11 and the steel column base plate 41.

[0047] It is easy to understand that a buffer layer is provided on the contact surface between the support part 11 and the steel column base plate 41, which can effectively reduce the rigid contact pressure between the support part 11 and the steel column base plate 41, avoid wear and scratches during installation or under stress, and protect the surface integrity of the steel column base plate 41; and enhance the friction between the support part 11 and the steel column base plate 41, making the support more stable and preventing the steel column 4 from shifting during adjustment.

[0048] Specifically, the buffer layer can be made of elastic materials such as rubber or sponge. The buffer material of appropriate size is cut according to the contact area between the support part 11 and the steel column base plate 41.

[0049] Furthermore, the support member 1 is a Z-shaped support member, with the side arm of the Z-shaped support member at the high position being the lifting part 12 and the side arm at the low position being the support part 11.

[0050] In a straightforward manner, the Z-shaped support is used, with the higher side arm designated as the lifting section 12 and the lower side arm designated as the support section 11. The Z-shaped support effectively utilizes space, providing sufficient installation and operation space for the adjusting component 2 within the limited vertical space, thus solving the problem of small-gap adjustment. At the same time, the Z-shaped structure naturally creates a height difference, clearly defining the functional divisions between the lifting section 12 and the support section 11, facilitating the application of force by the adjusting component 2. Furthermore, the support section 11 can fit against the steel column base plate 41 with a larger area, ensuring support stability. The lifting section 12 can precisely transmit the adjustment force, achieving efficient and accurate adjustment of the height of the steel column base plate 41.

[0051] Specifically, the Z-shaped support can be made of steel plate with a thickness of not less than 20mm, and the straight section of the lifting part 12 should not be less than 150mm. In addition, the support can also be U-shaped, as long as it can facilitate the placement of the adjusting part 2.

[0052] Furthermore, the support part 11 and the lifting part 12 are connected by a connecting arm 13, and the connecting arm 13 is provided with a plurality of positioning holes 14 in the vertical direction;

[0053] It also includes a clamping member 3, which is disposed on the upper side of the support part 11. One end of the clamping member 3 is connected to the positioning hole 14 through the connector 15, and the other end is attached to the steel column base plate 41.

[0054] It is easy to understand that the support part 11 and the lifting part 12 are connected by a connecting arm 13 with a positioning hole 14, and a clamping part 3 is provided in conjunction. By adjusting the connection position of the clamping part 3 with different positioning holes 14, the thickness of the steel column base plate 41 of different specifications can be flexibly adapted, enhancing the versatility of the device. One end of the clamping part 3 is fixed to the positioning hole 14, and the other end overlaps the steel column base plate 41. It can effectively limit the steel column 4 during the adjustment of the height of the steel column base plate 41, prevent the steel column 4 from displacing in the horizontal direction, ensure the accuracy of the positioning adjustment of the steel column 4, and also provide additional fixed support for the steel column 4, improving the overall structural stability.

[0055] Specifically, the connector 15 can be a combination of bolts and nuts. In a specific configuration, a through hole is made at one end of the clamping member 3, and the bolt is passed through the through hole of the clamping member 3 and the positioning hole 14 on the connecting arm 13. Then, a nut is screwed onto the other end of the bolt for fixation. Tightening the nut securely connects the clamping member 3 to the connecting arm 13. Alternatively, a pin can be used as the connector 15. The pin is inserted into the clamping member 3 and the positioning hole 14, and the pin's limiting action allows for quick connection and disassembly of the clamping member 3 and the connecting arm 13, facilitating adjustment of the clamping member 3's position according to actual needs. The support part 11, the connecting arm 13, and the lifting part 12 are integrally formed, or fixed by welding or fasteners; no specific restrictions are placed here.

[0056] Furthermore, a buffer layer is provided on the contact surface between the clamping member 3 and the steel column base plate 41.

[0057] It is easy to understand that a buffer layer is provided on the contact surface between the clamping member 3 and the steel column base plate 41, which can effectively reduce the rigid contact pressure between the clamping member 3 and the steel column base plate 41, avoid wear and scratches during installation or under stress, and protect the surface integrity of the steel column base plate 41; and enhance the friction between the clamping member 3 and the steel column base plate 41, making the support more stable and preventing the steel column 4 from shifting during adjustment.

[0058] Specifically, the buffer layer can be made of elastic materials such as rubber or sponge. The buffer material of appropriate size is cut according to the contact area between the clamping part 3 and the steel column base plate 41.

[0059] Furthermore, the positioning holes 14 are arranged in a linear array along the vertical direction, and the spacing between adjacent positioning holes 14 is 0.2-0.5 times the thickness of the steel column base plate 41.

[0060] It is easy to understand that the positioning holes 14 are arranged in a linear array along the vertical direction with an adjacent spacing of 0.2-0.5 times the thickness of the steel column base plate 41, allowing the device to flexibly adapt to steel column base plates 41 of different thicknesses. The linear array arrangement allows the clamping element 3 to be adjusted in multiple positions, ensuring that a suitable positioning hole 14 can be found for connection regardless of the thickness range of the steel column base plate 41, enhancing the device's versatility. Setting the spacing to 0.2-0.5 times the thickness avoids both excessively large spacing that would prevent precise adaptation to some thicknesses of the steel column base plate 41 and excessively small spacing that would complicate the processing of the positioning holes 14 and increase costs, thus achieving a balance between adaptability and economy.

[0061] Furthermore, the adjusting component 2 is a jack, and the piston rod end of the jack is detachably connected to the lifting part 12.

[0062] In a straightforward manner, the adjusting component 2 employs a jack with its piston rod end detachably connected to the lifting section 12. This utilizes the jack's lifting force to adjust the height of the steel column base plate 41, meeting the high-precision requirements of steel structure installation. Furthermore, the detachable connection allows for easy disassembly of the jack after adjustment, facilitating reuse in different construction scenarios and improving equipment utilization. It also reduces space occupation during transportation and storage, lowering transportation costs and storage difficulties. Additionally, it allows for rapid replacement and repair in case of jack malfunction, ensuring the smooth operation of the steel column 4's base positioning adjustment. The adjusting component 2 can also be a telescopic rod, etc.

[0063] Furthermore, the lifting part 12 is recessed on the side near the adjusting member 2 to form a guide hole, and the end of the piston rod is slidably inserted into the guide hole.

[0064] In a straightforward manner, the guide hole guides the sliding of the piston rod, ensuring that the piston rod always moves vertically upward during the lifting process, thus preventing deviation that could lead to dispersed or uneven lifting force. This improves the accuracy and stability of the height adjustment of the steel column base plate 41. The guide hole's limiting function effectively prevents the piston rod from swaying during the lifting process, enhancing the reliability of the connection between the jack and the lifting part 12, reducing equipment wear caused by swaying, and ensuring the safe execution of the positioning and adjustment work.

[0065] In an optional embodiment, if the support part 11 is directly supported by a jack, a buffer structure needs to be provided between the jack and the support part 11 to achieve flexible contact. Preferably, the buffer structure can be a 50mm-80mm square wooden block.

[0066] It should be noted that the outer perimeter of the steel structure is provided with studs 42. The studs 42 are welded to the perimeter of the steel column using specialized welding equipment. By setting studs 42 on the steel beam, the concrete floor slab and the steel beam are connected as a whole, so that the floor slab can work together with the steel beam when bearing pressure, thereby improving the load-bearing capacity and spatial performance of the structure.

[0067] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
