Description

Technical Field

[0001] The invention relates to a box-type frame structure and a prefabricated module, belonging to the technical field of assembled buildings. Background Art

[0002] Existing box-type prefabricated building modules are usually steel structures, but problems such as fire prevention and corrosion resistance of steel structure modules have not been well solved.

[0003] Modular buildings have a higher assembly rate than traditional prefabricated buildings, and are more conducive to the factoryization and industrialization of buildings. They are an important direction for the development of concrete-converted buildings. The patent document with publication number CN110984363A discloses a non-metallic (concrete) building module and its construction method, which introduces the stacking construction (connection) method of the building modules. High-performance concrete prefabricated integral modules solve the problems encountered by steel structure modules. At the same time, the durability, overall rigidity, and comfort of the modules are more advantageous. How to manufacture box-type non-metallic prefabricated modules and how to ensure the stability and safety of prefabricated modules are technical problems that need to be solved in the development of box-type non-metallic prefabricated modules.

[0004] In order to solve the weakness of low tensile strength of concrete, traditional prefabricated concrete components are provided with criss-cross steel frames (also called steel cages) inside the prefabricated components. However, the traditional steel frame form, on the one hand, uses a large amount of steel bars, which is not conducive to reducing the production cost and weight of the prefabricated modules; on the other hand, the steel frame makes the prefabricated modules have a large elastic deformation of the panel surface when subjected to external forces, and the end structure strength is insufficient, which is not conducive to the long-term stability of the prefabricated modules. Summary of the invention

[0005] In order to prepare safe and reliable prefabricated modules, the present invention provides a box-type frame structure and a prefabricated module, and the specific technical scheme is as follows.

[0006] A box-type frame structure, characterized in that it comprises an upper frame, a lower frame and columns, the upper frame and the lower frame are both rectangular, the upper frame and the lower frame each comprise two longitudinal beams and two transverse beams, and the two ends of each longitudinal beam are respectively fixedly connected to the ends of the two transverse beams;

[0007] The four corners of the upper frame and the four corners of the lower frame are connected by the columns, the upper ends of the columns are connected to the ends of the crossbeams of the upper frame, and the lower ends of the columns are connected to the ends of the crossbeams of the lower frame;

[0008] The upper frame and the lower frame both include a plurality of intermediate beams, the extension direction of the intermediate beams is parallel to the extension direction of the longitudinal beams, the two ends of the intermediate beams of the upper frame are respectively fixedly connected to the two cross beams of the upper frame, and the two ends of the intermediate beams of the lower frame are respectively fixedly connected to the two cross beams of the lower frame;

[0009] A plurality of intermediate columns are arranged between the cross beam of the upper frame and the corresponding cross beam of the lower frame, the extension direction of the intermediate columns is parallel to the extension direction of the columns, the upper ends of the intermediate columns are fixedly connected to the cross beam of the upper frame, and the lower ends of the intermediate columns are fixedly connected to the cross beam of the lower frame.

[0010] By adopting the above technical solution, the skeleton of the box-type prefabricated module adopts a frame structure. The frame structure has strong integrity and good stability, and can provide long-term reliability support for the prefabricated module. Compared with the steel cage skeleton, the frame structure is superior in structural strength. The production efficiency of the frame structure will also be higher, which is more conducive to realizing automated production.

[0011] Furthermore, the longitudinal beam and the middle beam are both plate structures, and the plate surface of the plate structure is perpendicular to the extension direction of the cross beam. The longitudinal beam and the middle beam adopt plate structures, which, on the one hand, is conducive to improving the rigidity of the longitudinal beam and the middle beam in the vertical plane and preventing the top plate and the bottom plate of the prefabricated module from undergoing large deformation; on the other hand, it is conducive to reducing the overall weight of the longitudinal beam and the middle beam and saving material consumption. Preferably, the thickness of the two ends of the longitudinal beam and the middle beam is greater than the thickness of the middle part. That is, the two ends of the longitudinal beam and the middle beam are subjected to a haunch (thickening) treatment, which is conducive to improving the connection strength of the longitudinal beam, the middle beam and the cross beam, and is greatly helpful to improving the end (edge) structural strength of the prefabricated module. The end of the prefabricated module is the main component that bears the load, and the lifting of the front end of the end structure makes it possible to build a higher (more floors) modular building.

[0012] Furthermore, the middle column adopts a plate structure, and the plate surface of the plate structure is perpendicular to the extension direction of the cross beam. The middle column adopts a plate structure, which is conducive to reducing the overall weight of the middle column and saving material consumption. Preferably, the thickness of the two ends of the middle column is greater than the thickness of the middle part.

[0013] Furthermore, the middle beam is provided with a plurality of through holes along its extension direction. The provision of these through holes is beneficial to reducing the weight of the middle beam on the one hand, and on the other hand, when preparing the prefabricated module, it is helpful to fully combine the non-metallic material (concrete or ultra-high performance concrete) with the middle beam, thereby improving the integrity of the prefabricated module.

[0014] Furthermore, the middle column is provided with a plurality of through holes along its extension direction.

[0015] Furthermore, connecting steel bars are fixedly provided at both ends of the cross beam of the upper frame, and the upper ends of the connecting steel bars are higher than the upper surface of the cross beam of the upper frame.

[0016] Furthermore, both ends of the crossbeam of the lower frame are fixedly provided with embedded sleeves, the opening of the embedded sleeves faces downward, and the embedded sleeves and the connecting steel bars are on the same straight line in the vertical direction. By providing the connecting steel bars and the embedded sleeves, the connecting steel bars can be inserted into the embedded sleeves when the upper and lower prefabricated modules are stacked, so as to facilitate quick connection.

[0017] Furthermore, the upper frame and the lower frame are both made of metal materials. The longitudinal beams, cross beams, columns and other components are fixedly connected together by welding to ensure the stability and reliability of the frame structure.

[0018] It is anticipated that the same inventive concept, the present invention also relates to a prefabricated module, the prefabricated module includes the above-mentioned box-type frame structure, the box-type frame structure is located inside the prefabricated module, the prefabricated module includes a bottom plate, a first side plate, a top plate and a second side plate connected in sequence, the upper frame is located inside the top plate, the lower frame is located inside the bottom plate, a part of the columns are located inside the first side plate, and another part of the columns are located inside the second side plate.

[0019] The box-type frame structure of the present invention can ensure the overall structural strength of the prefabricated modules, prevent the top plate and the bottom plate of the prefabricated modules from undergoing large deformation, and is beneficial to improving the end strength of the prefabricated modules, making it convenient to build modular buildings with higher floors. At the same time, the box-type frame structure of the present application is beneficial to improving the production efficiency of the prefabricated modules and is convenient for realizing automated production.
