Description

Technical Field

[0001] This utility model belongs to the field of building facilities technology and relates to a steel column beam concrete structure building. Background Technology

[0002] Steel structures are widely used in the construction industry due to their light weight, convenient construction, and high strength. Steel structures mainly consist of steel beams and columns made of shaped steel, and these components are typically connected by bolts. For example, Chinese patent literature discloses a steel structure (authorization announcement number: CN209568542U) that achieves bolted connections between steel columns and beams by fixing column sleeves with connection ports on their sides to the steel columns. Chinese patent literature also discloses a C-shaped steel bolted connection structure (authorization announcement number: CN207268027U). This bolted connection structure uses C-shaped steel connectors with a cross-sectional dimension 1-2 mm larger than the C-shaped steel to be connected, installed at the connection node of the two C-shaped steel sections to be connected. Symmetrical through holes evenly distributed on both sides of the web of the C-shaped steel connector correspond to the connection holes on the webs of the two C-shaped steel sections to be connected, and the two C-shaped steel sections are connected as a single unit by bolts, thus achieving a bolted connection between two steel beams made of C-shaped steel.

[0003] The current connection methods for steel structures have the following shortcomings in use: In order to achieve bolted connections between steel columns and steel beams, or between steel beams, bolt holes need to be made at corresponding positions on the steel columns and steel beams, or between two steel beams. On the one hand, making holes will affect the structural bearing capacity; on the other hand, due to processing and assembly errors, the bolt holes between the steel columns and steel beams, or between two steel beams, may be misaligned, making assembly and construction difficult. In addition, the rigidity of the connection between the steel columns and steel beams, or between two steel beams, is poor, and they are prone to loosening when subjected to dynamic loads over a long period of time, affecting the stability of the steel structure. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a steel column-beam concrete structure building. The technical problem this invention aims to solve is how to improve the structural stability of steel column-beam concrete structures while simultaneously making assembly and construction more convenient.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A steel column-beam concrete structure is characterized by comprising main beams, secondary beams, at least two parallel main beams, at least two parallel secondary beams, several secondary beams, and several tubular columns. The main beams, secondary beams, main secondary beams, and secondary secondary beams are all C-shaped steel or rectangular steel pipe beams with their openings facing upwards. Each column has a U-shaped notch at its top. Both ends of the main beam are respectively inserted downwards into the U-shaped notches of the two columns. The secondary beams are perpendicular to the main beams, and both ends of the secondary beams are respectively hooked downwards onto the ends of the two main beams. The main secondary beams are perpendicular to the two main beams, and both ends of the main secondary beams are respectively attached to the two main beams. Both ends of the secondary secondary beams are respectively attached between the two main secondary beams or between the secondary beams and the main secondary beams. The upper surfaces of the main beams, secondary beams, main secondary beams, and secondary secondary beams are flush.

[0007] The ends of the two main beams and the two secondary beams of this steel column-beam concrete structure are interlocked to form a rectangular frame. Several primary and secondary beams and several secondary beams are also interlocked between the main and secondary beams. Specifically, the primary and secondary beams are vertically positioned between the two main beams, with their ends respectively attached to the two main beams. The two ends of the secondary beams are respectively attached to the two primary and secondary beams or to the primary and secondary beams. This interlocking arrangement of primary and secondary beams forms the internal support skeleton of the rectangular frame. Four columns support the four interlocking points of the main and secondary beams, creating a stable node structure. This structure can mitigate the slippage of the main and secondary beams during earthquake-induced column settlement, improving the structural stability of the steel column-beam concrete structure. Furthermore, the interlocking structure facilitates assembly, and the assembled main beams, secondary beams, primary and secondary beams, and secondary beams have flush upper surfaces, further facilitating subsequent construction work.

[0008] In the aforementioned steel column-beam concrete structure, each main beam has a downward-facing first slit along its upper edge, and both ends of the secondary beam are respectively embedded downward into the first slits of the two main beams. This facilitates the assembly and construction of the main and secondary beams.

[0009] In the aforementioned steel column-beam concrete structure, a first positioning notch is provided on the upper edge of the opposite sidewalls of both main beams. Both ends of the main and secondary beams have a first locking part, and the two first locking parts are respectively hooked into the first positioning notches of the two main beams. This facilitates the assembly and construction of the main and secondary beams.

[0010] In the aforementioned steel column-beam concrete structure, both the secondary beam and the main and secondary beams have second positioning notches. Each end of the secondary beam has a second locking part. At least one secondary beam is located between two main and secondary beams, and its two second locking parts are respectively hooked into the second positioning notches of the two main and secondary beams. At least one secondary beam is located between the secondary beam and the main and secondary beams, and its two second locking parts are respectively hooked into the second positioning notches on the secondary beam and the main and secondary beams. This facilitates the assembly and construction of the secondary beams.

[0011] In the aforementioned steel-column-beam concrete structure, one end of the secondary beam extends beyond the outer side of one of the main beams and has a third latching part at the extended portion. This third latching part is attached to the top edge of the column, while the other end of the secondary beam is located inside another main beam. This creates a staggered interlocking structure between the main beam, secondary beam, and column, improving the stability of the connection. Furthermore, the fact that the other end of the secondary beam is inside another main beam allows the steel-column-beam concrete structure to be extended laterally outwards according to actual usage requirements.

[0012] In the aforementioned steel-column-beam concrete structure, one end of the main beam extends beyond the outer side of one of the secondary beams. The end of the main beam intersects with the end of the secondary beam, and the main beam has a fourth locking part at the part extending beyond the secondary beam. A second downward-facing slit is located on the column below the main beam, and the fourth locking part is hooked into the second slit. The other end of the main beam is located inside the other secondary beam. This further forms an interlocking structure between the main beam, secondary beam, and column, further improving the stability of the connection. The fact that the other end of the main beam is inside the other secondary beam allows the steel-column-beam concrete structure to continue to expand laterally outwards according to actual usage requirements.

[0013] In the aforementioned steel-column-beam concrete structure, both ends of the main beam and secondary beam have clearance holes on their bottom surfaces directly above the columns, and both sides of the secondary beam have clearance notches. These clearance holes connect the main beam and the columns, or the secondary beam and the columns, facilitating the formation of a unified structure when concrete is poured into the main beam, secondary beam, main secondary beams, secondary secondary beams, and columns, thereby further improving the structural stability of the steel-column-beam concrete structure.

[0014] In the aforementioned steel column-beam concrete structure, when the main beams, secondary beams, primary secondary beams, and secondary secondary beams are C-shaped steel, each of the main beams, secondary beams, primary secondary beams, and secondary secondary beams has several spaced reinforcing plates at its openings. These reinforcing plates enhance the structural strength of the C-shaped steel main beams, secondary beams, primary secondary beams, and secondary secondary beams, preventing deformation at the openings due to stress.

[0015] In the aforementioned steel-column-beam concrete structure, the edges of the U-shaped notches of the main beam and the column are welded and fixed, and the edges of the first cuts of the main beam and the secondary beam are welded and fixed. This further improves the stability of the connections between the main beam and the column, as well as between the secondary beam and the main beam, thereby enhancing the structural stability of the steel-column-beam concrete structure.

[0016] In the aforementioned steel-column-beam concrete structure, the first snap-fit ​​portion of the primary and secondary beams is welded and fixed to the edge of the first positioning notch of the primary beam. This further improves the stability of the connection between the primary and secondary beams and the primary beam, thereby enhancing the structural stability of the steel-column-beam concrete structure.

[0017] Compared with existing technologies, the advantages of this steel column-beam concrete structure are as follows: the ends of the two main beams and the two secondary beams of this steel column-beam concrete structure are interlocked to form a rectangular frame. At the same time, several main secondary beams and several secondary secondary beams are interlocked between the main beams and secondary beams to form the internal support skeleton of the rectangular frame. In addition, four columns support the four interlocking parts of the main beams and secondary beams, thus forming a stable node structure. In the event of earthquake column settlement, the displacement of the main beams and secondary beams can be reduced, thereby improving the structural stability of the steel column-beam concrete structure. At the same time, the interlocking structure makes assembly and construction more convenient. Attached Figure Description

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0025] A steel column-beam concrete structure building, referring to Figure 1-5 The system includes main and secondary beams 1, at least two parallel main beams 2, at least two parallel secondary beams 3, several secondary beams 4, and several tubular columns 5. The main beams 2, secondary beams 3, main and secondary beams 1, and secondary beams 4 are all C-shaped steel or rectangular steel pipe beams with their openings facing upwards. Each column 5 has a U-shaped notch 5a at its top. Both ends of each main beam 2 are respectively inserted downwards into the U-shaped notches 5a of two columns 5. The upper edge of each main beam 2 has a downward-facing first slit 2a. The secondary beams 3 are perpendicular to the main beams 2, and both ends of each secondary beam 3 are respectively inserted downwards into the first slits 2a of two main beams 2. The primary and secondary beams 1 are vertically arranged between two primary beams 2. The upper edges of the opposite sidewalls of the two primary beams 2 are provided with first positioning notches 2b. Both ends of the primary and secondary beams 1 are provided with first latching parts 1a, and the two first latching parts 1a are respectively attached to the first positioning notches 2b of the two primary beams 2. The secondary beam 3 or the primary and secondary beams 1 are provided with second positioning notches 6. Both ends of the secondary beam 4 are provided with second latching parts 4a, and the two second latching parts 4a are respectively attached to the second positioning notches 6 of the two primary and secondary beams 1 or the secondary beam 3 and the primary and secondary beams 1. The upper surfaces of the primary beams 2, secondary beams 3, primary and secondary beams 1 and secondary beams 4 are flush.

[0026] Reference Figure 2 Specifically, both ends of the main beam 2 and the secondary beam 3 have clearance holes 7 on their bottom surfaces directly above the column 5, and clearance notches 3b are provided on both side walls at both ends of the secondary beam 3.

[0027] Reference Figure 1 and Figure 2 More specifically, one end of the secondary beam 3 extends outward from the outside of one of the main beams 2 and has a third latching part 3a at the extended part. The third latching part 3a is attached to the top edge of the column 5. The other end of the secondary beam 3 is located inside the other main beam 2. One end of the main beam 2 extends outward from the outside of one of the secondary beams 3. The end of one of the main beams 2 and the end of the secondary beam 3 are arranged to cross each other. The main beam 2 has a fourth latching part 2c at the part extending outward from the secondary beam 3. The column 5 located below the main beam 2 has a downward-opening second slit 5b. The fourth latching part 2c is attached to the second slit 5b. The other end of the main beam 2 is located inside the other secondary beam 3.

[0028] The ends of the two main beams 2 and the two secondary beams 3 of this steel column-beam concrete structure are interlocked to form a rectangular frame. Furthermore, this steel column-beam concrete structure also includes several primary and secondary beams 1 and several secondary beams 4 interlaced between the main beams 2 and the secondary beams 3. Specifically, both ends of the primary and secondary beams 1 are interlocked with the side walls of the two main beams 2, and both ends of the secondary beams 4 are interlocked with the side walls of the two primary and secondary beams 1, or the secondary beams 3 are interlocked with the side walls of the primary and secondary beams 1, thus forming a rectangular frame through the interlaced arrangement of primary and secondary beams 1 and several secondary beams 4. The internal support frame of the structure, along with four columns 5 supporting the four interlocking points of the main beam 2 and the secondary beam 3, forms a stable node structure. This structure can mitigate the misalignment of the main beam and the secondary beam when the columns settle during an earthquake, thereby improving the structural stability of the steel column-beam concrete structure. At the same time, the interlocking structure makes assembly construction more convenient, and the upper surfaces of the assembled main beam 2, secondary beam 3, primary secondary beam 1, and secondary secondary beam 4 are flush (the width of the main beam 2, secondary beam 3, primary secondary beam 1, and secondary secondary beam 4 decreases sequentially along the vertical direction), which further facilitates subsequent construction operations.

[0029] In addition, to further improve the structural stability of the steel column-beam concrete structure, in this embodiment, when the main beam 2, secondary beam 3, main secondary beam 1, and secondary secondary beam 4 are C-shaped steel, each of the main beam 2, secondary beam 3, main secondary beam 1, and secondary secondary beam 4 has a number of spaced reinforcing plates 8 at its opening; preferably, the edges of the U-shaped notch 5a of the main beam 2 and the column 5 are welded and fixed, the edges of the first cut 2a of the secondary beam 3 and the main beam 2 are welded and fixed, the edges of the first snap-fit ​​part 1a of the main secondary beam 1 and the first positioning notch 2b of the main beam 2 are welded and fixed, and the edges of the second snap-fit ​​part 4a of the secondary secondary beam 4 and the edges of the second positioning notch 6 of the main secondary beam 1 or the secondary beam 3 are welded and fixed.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
