Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a steel structure column foot connection joint. Background Art

[0002] The connection joint of the steel column foot is a crucial part of the steel structure project. It ensures the stability and safety of the entire structure. First, according to the design drawings and project requirements, anchor bolts are embedded in the predetermined position. After the anchor bolts are embedded, concrete is poured to fix the anchor bolts. After the concrete reaches sufficient strength, the column foot plate is installed. The column foot plate is placed in the predetermined position and connected with the embedded anchor bolts. The steel beam is placed on the column foot plate and positioned according to the design requirements. The level and other tools are used to adjust the horizontality and verticality of the steel beam to ensure that the connection between it and the column foot plate is accurate and tight.

[0003] The patent with publication number CN216130352U discloses an exposed rigid column base, which is arranged on the foundation surface. The base is used to fix and install the vertically arranged steel column. The bottom of the base is provided with an anchor member embedded below the foundation surface; the anchor member includes a horizontal plate and at least two vertical screws vertically fixed on the horizontal plate, and the upper part of the vertical screw is detachably connected to the base; although the above device solves the problem of poor stability of the existing exposed rigid column base when subjected to axial force and torque.

[0004] However, the above technical solution still has the following problems:

[0005] The inability to correct the horizontal angle of the column base plate and the embedded layer, and the stiffening plate being fixed on the column base plate result in poor adaptability to the steel beam. It is difficult to make precise angle adjustments during the embedded stage. The embedded process usually occurs before concrete pouring. Once the concrete solidifies, the position of the column base plate and the embedded layer is basically fixed and can no longer be adjusted. If there is an angle deviation during embeddedness, it will make it difficult to ensure verticality during subsequent steel beam installation, thereby affecting the stability and bearing capacity of the entire steel structure. The fixed stiffening plate limits the flexibility of the column base plate, making it difficult to adapt to different installation conditions or changes in steel beam size. Due to the fixed position and size limitations of the stiffening plate, the rigid column base may not be able to fully adapt to steel beams of different sizes, shapes or installation positions. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a steel structure column base connection joint to at least solve one of the problems raised by the background technology, such as: improving the construction accuracy of the rigid column base during the pre-embedded stage, enhancing the stability of the steel structure and improving the construction flexibility.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel structure column base connection joint, including a column base plate, an external steel beam connected to the surface of the column base plate and an anchor bolt passing through the surface of the column base plate, a plurality of stiffening plates are provided on the surface of the column base plate, the stiffening plates and the column base plate can be detachably arranged, a gasket is sleeved on the outer side of the anchor bolt, one side surface of the gasket is fitted and connected to the bottom of the external steel beam, a circular opening is opened on the surface of the column base plate, a circular opening is passed through one end of the anchor bolt, and a column base bolt is sleeved.

[0008] Furthermore, a plurality of slide grooves are provided on the surface of the column foot bottom plate, and the bottom side of the stiffening plate is fitted and connected with the inner wall of the slide groove.

[0009] Furthermore, a thread line is provided on the outer side of the anchor bolt, and the inner ring of the gasket ring is threadedly connected to the thread line.

[0010] Further, the gasket surface and the anchor bolt are arranged vertically.

[0011] Furthermore, a scale groove is provided on the outer side of the anchor bolt.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model aims at the characteristics of the rigid column foot in the pre-embedded stage, so that the anchor bolts of the steel structure column foot connection joints have scale lines, gaskets maintain the levelness of the column foot bottom plate, the stiffening plates are welded to the steel beams at a later stage and have the function of guiding the stiffening plates, thereby ensuring that the column foot bottom plate reaches a high level and stability in the pre-embedded stage, reducing the adjustment work in the subsequent installation process and improving the overall construction accuracy. The column foot bottom plate can be kept level in the pre-embedded stage, which helps to reduce the risk of structural instability caused by installation errors. Construction personnel can flexibly adjust the position and size of the stiffening plates according to actual on-site conditions to adapt to steel beams of different sizes and shapes.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] like Figures 1 to 4 As shown, a connection joint of a steel structure column base includes a column base plate 1, an external steel beam 2 connected to the surface of the column base plate 1 and an anchor bolt 3 penetrating the surface of the column base plate 1, a plurality of stiffening plates 4 are provided on the surface of the column base plate 1, the stiffening plates 4 and the column base plate 1 can be detachably arranged, a gasket 5 is sleeved on the outer side of the anchor bolt 3, one side surface of the gasket 5 is fitted and connected to the bottom of the external steel beam 2, a circular opening 102 is opened on the surface of the column base plate 1, one end of the anchor bolt 3 is penetrated by the circular opening 102, and a column base bolt 6 is sleeved.

[0021] like Figure 1 As shown, a steel structure column foot connection joint in the utility model is similar to the existing exposed rigid column foot structure, such as the exposed rigid column foot disclosed in the patent publication number CN216130352U. The main improvement of the utility model is to reduce the operation difficulty of construction personnel and improve the quality and efficiency of steel structure engineering. Figures 1 to 4 As shown, when a steel structure column foot connection joint in the utility model is used, the anchor bolt 3 passes through the circular opening 102 of the column foot bottom plate 1 and is tightly connected to the foundation concrete, ensuring the firmness between the column foot bottom plate 1 and the foundation concrete. The gasket 5 is placed on the outside of the anchor bolt 3 as a supporting and adjusting device, and is tightly fitted with the bottom of the column foot bottom plate 1, so that when the column foot bottom plate 1 is installed on the foundation concrete, a stable supporting surface can be provided to ensure that the column foot bottom plate 1 can maintain a horizontal state. The detachable setting of the stiffening plate 4 and the column foot bottom plate 1 is pre- The stiffening plates 4 are placed in advance during the embedding stage, and are welded and fixed after the external steel beams 2 are installed in place. This not only improves the construction efficiency, but also allows the position and number of the stiffening plates 4 to be flexibly adjusted according to actual needs to adapt to different engineering conditions. The installation of the column foot bolts 6 further enhances the firmness of the connection and prevents the column foot from loosening or shifting during the force-bearing process. This type of steel structure column foot connection joint improves the stability, reliability, construction convenience and flexibility of the connection during the pre-embedded stage, providing a solid foundation for the subsequent steel structure installation.

[0022] like Figures 1 to 3 As shown, a plurality of slide grooves 101 are provided on the surface of the column foot bottom plate 1, and the bottom side of the stiffening plate 4 is fitted and connected with the inner wall of the slide groove 101.

[0023] Specifically, the design of setting the slide groove 101 provides a precise positioning and installation path for the stiffening plate 4. The fit connection between the bottom side of the stiffening plate 4 and the inner wall of the slide groove 101 ensures that the position of the stiffening plate 4 on the column foot base plate 1 is accurate, which helps to avoid position deviation during the installation process and improves the installation accuracy and efficiency. The stiffening plate 4, as an important component for enhancing structural rigidity, is closely connected to the column foot base plate 1 through the slide groove 101, which can effectively disperse and transfer the load and enhance the bearing capacity of the entire column foot.

[0024] like Figure 4 As shown, a thread line 7 is provided on the outer side of the anchor bolt 3, and the inner ring of the washer 5 is threadedly connected to the thread line 7.

[0025] Specifically, the setting of the threaded wire 7 makes the connection between the anchor bolt 3 and the gasket 5 tighter and stronger. When the threaded wire 7 on the inner ring of the gasket 5 and the outer side of the anchor bolt 3 are screwed together, a mechanical locking effect is formed between them, thereby enhancing the stability and bearing capacity of the connection. When the steel structure is subjected to external force, the threaded connection can effectively resist tension and torque, and maintain the tightness and stability of the connection.

[0026] like Figure 4 As shown, the surface of the gasket 5 and the anchor bolt 3 are arranged vertically.

[0027] Specifically, the vertical setting of the gasket 5 and the anchor 3 makes it easy for construction workers to check and adjust. Construction workers can intuitively observe the relative positions of the gasket 5 and the anchor 3. If they find that they are not vertical or there is a deviation, they can make adjustments in time to ensure that the horizontality of the column foot plate 1 meets the design requirements.

[0028] like Figure 4 As shown, a scale groove 8 is provided on the outer side of the anchor bolt 3 .

[0029] Specifically, the setting of the scale groove 8 provides construction personnel with an accurate positioning and measurement basis. By observing and measuring the position and depth of the scale groove 8, construction personnel can accurately determine the buried position and depth of the anchor bolt 3, thereby ensuring that the connection between the column base plate 1 and the foundation concrete meets the design requirements. This helps to improve the accuracy and reliability of the installation and avoid installation deviations or loose connections.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
