Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to the field of lattice column base technology, specifically an adjustable lattice column base. Background Technology

[0002] Building construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of structures, or the process of turning the lines on design drawings into a physical object at a designated location. It includes foundation construction, main structure construction, roofing construction, and decoration construction.

[0003] In steel structure construction, the performance of the lattice column base is crucial to the overall quality of the steel structure building. Currently, in steel structure construction, traditional lattice column bases are all used to support the structure on a horizontal support surface and are not adjustable, thus presenting significant drawbacks:

[0004] First, during construction, the geological conditions at the construction site are often highly uncertain. The foundation may be uneven, the soil may be loose and uneven, etc. This makes it difficult for the existing lattice column base to ensure that the lattice column can be installed vertically and stably on such a complex foundation, thus affecting the initial installation accuracy and stability of the entire steel structure.

[0005] Secondly, during the temporary support of lattice columns, the lack of effective adjustment methods makes it difficult for construction workers to precisely adjust the lattice columns to a completely vertical state. This is especially true in the construction of large steel structure stadiums and long-span trusses, where the requirements for the verticality of the lattice columns are extremely high. Even a slight deviation in verticality can lead to difficulties in subsequent steel structure installation and affect the stress performance and stability of the entire structure.

[0006] Therefore, existing lattice column bases cannot adequately cope with the complexity of foundation conditions and the high requirements for construction precision during steel structure construction, and there is an urgent need for a new type of lattice column base that can effectively solve these problems.

[0047] The lower pad 13 can be a steel plate, the material of which can be the same as that of the supporting base plate 1, and the thickness can be 40mm to 60mm.

[0048] The number of connecting plates 5 can be determined as needed. The term "multiple plates" refers to two or more plates. In a specific embodiment of this utility model, the number of connecting plates 5 is four, and the four connecting plates 5 are distributed at the four corners of a rectangle.

[0049] The connecting plate 5 can have any suitable shape; please refer to [link / reference].

[0053] The thickness of the supporting base plate 1 can be determined as needed. In a specific embodiment of this utility model, the thickness of the supporting base plate 1 is 25mm.

[0054] The supporting base plate 1 serves as the basic support of this utility model and is laid on the foundation 16. Its area is determined by the force distribution of this utility model, and generally each side is 200mm to 500mm longer than the lower pad plate 13. The supporting base plate 1 can evenly distribute the load transmitted from the lattice column 17 and prevent excessive local pressure on the foundation 16.

[0055] The bubble level 4 should be positioned so that it is easy to observe and can accurately reflect the levelness of the support platform 3, thereby determining the verticality of the lattice column 17. Preferably, the accuracy of the bubble level 4 can be 0.5-1 mm / m per grid.

[0056] In use, after placing this utility model on the foundation 16, first observe the level bubble 4 to determine the levelness of the support platform 3. If the level bubble 4 indicates that the support platform 3 is not level, adjust the lifting device 2 according to the following steps: For cases where the support platform 3 is locally low, start the corresponding lifting device 2 and slowly control the support platform 3 to rise, with each rise controlled within the range of 5mm to 10mm, while closely observing the changes in the level bubble 4. According to the indication of the level bubble 4, adjust the lifting amount of the lifting device 2 in sequence, repeatedly adjusting until the level bubble 4 indicates that the support platform 3 is level; Set (e.g., weld) the column 18 of the lattice column 17 onto the connecting plate 5. After the lattice column 17 is installed, adjust the verticality: Observe the level bubble 4 to determine the levelness of the support platform 3. If the level bubble 4 indicates that the support platform 3 is not level, adjust the lifting device 2 according to the above steps until the level bubble 4 indicates that the support platform 3 is level and the verticality of the lattice column 17 meets the design requirements.

[0057] During long-term use, the status of the level bubble 4 should be observed regularly. If the level bubble 4 shows a change in the levelness of the support platform 3, it may indicate that the foundation 16 has experienced slight settlement or that the external load has caused a change in the verticality of the lattice column 17. The lifting device 2 can be used for secondary adjustment to ensure that the lattice column 17 remains vertical.

[0058] Therefore, this utility model uses a bubble level for real-time monitoring of the support platform's levelness and a lifting device to precisely adjust the verticality of the lattice column. This effectively ensures the vertical installation and structural stability of the lattice column during the construction and long-term use of large steel structure buildings such as steel structure stadiums and large-span trusses. It ensures that the lattice column adapts to complex foundation conditions, meets high-precision installation requirements, and solves the shortcomings of existing lattice column bases in terms of foundation adaptability, verticality adjustment accuracy, and long-term stability. This ensures the structural safety and stability of large steel structure buildings during construction and use.

[0059] This utility model is simple to operate, does not require manual disassembly of the work platform to cross obstacles, is flexible, precise and efficient, improves construction safety, and greatly saves labor and time costs.

[0060] In summary, the adjustable lattice column base of this utility model can be adjusted according to the flatness of the foundation and can also be adjusted for levelness, thus adapting to complex foundation conditions and meeting high-precision installation requirements. It has an ingenious design, simple structure, easy manufacturing, and low manufacturing cost, making it suitable for large-scale promotion and application.

[0061] Therefore, it is evident that the objective of this utility model has been fully and effectively achieved. The function and structural principles of this utility model have been demonstrated and explained in the embodiments.
