Description

Technical Field

[0001] The utility model belongs to the technical field of modular steel frame buildings, in particular to a modular steel frame structure with combined columns. Background Art

[0002] Modular steel frame buildings, as an emerging form of building industrialization, have the advantages of high integration, fast construction speed, flexible space layout and low environmental pollution. They have received widespread attention and application in recent years.

[0003] However, modular steel frame structures are different from ordinary steel frame structures. The columns between adjacent modules are arranged in parallel, and the columns of each module steel frame work independently. Therefore, a larger column cross-section is required to obtain sufficient bearing capacity, resulting in a large amount of steel used in the overall structure and high cost.

[0004] Therefore, a modular steel frame structure with composite columns is proposed. Utility Model Content

[0005] In order to solve the above technical problems, the utility model proposes a modular steel frame structure with combined columns.

[0006] To achieve the above objectives, the present invention provides a modular steel frame structure with combined columns, comprising:

[0007] A plurality of unit steel frames, wherein the unit steel frames are composed of a plurality of H-shaped steel columns and steel beams, and adjacent H-shaped steel columns on the plurality of unit steel frames are spliced together to form a composite column;

[0008] A plurality of gusset plates are arranged in parallel outside the outer flanges of the two H-shaped steel columns adjacent to each other on the left and right sides of the composite column, and first bolts are respectively provided at both ends of the gusset plates corresponding to the two H-shaped steel columns adjacent to each other on the left and right sides, and the first bolts connect the gusset plates and the two H-shaped steel columns adjacent to each other on the left and right sides;

[0009] The flanges of two H-shaped steel columns adjacent to each other in the composite column are connected to each other by a plurality of second bolts arranged in parallel.

[0010] Preferably, mounting bolt holes are provided at both ends of the gusset plate; a plurality of outer flange bolt holes are provided on the outer flange of the H-shaped steel column corresponding to the mounting bolt holes, and the outer flange bolt holes and the mounting bolt holes are both large circular holes, and the first bolt passes through the mounting bolt holes and the outer flange bolt holes to connect the gusset plate and the H-shaped steel column.

[0011] Preferably, the width of the gusset plate is the sum of the widths of the outer flanges of the two adjacent H-shaped steel columns on the left and right.

[0012] Preferably, inner flange bolt holes are opened at the flanges of the two adjacent H-shaped steel columns in front and behind, where they contact each other. The inner flange bolt holes are large circular holes, and the second bolts pass through the corresponding two inner flange bolt holes to connect the two adjacent H-shaped steel columns in front and behind.

[0013] Preferably, the second bolt is clearance-fitted with the inner flange bolt hole.

[0014] Compared with the prior art, the present invention has the following advantages and technical effects:

[0015] The four H-shaped steel columns, each derived from four different unit steel frames, abut each other. The adjacent H-shaped columns on the left and right are connected and secured via several tie plates. One end of the tie plate is bolted to the left H-shaped column via a first bolt, and the other end is bolted to the right H-shaped column via another first bolt, thus connecting the two adjacent H-shaped columns. The front and rear adjacent H-shaped columns are connected via a second bolt at their contacting flanges, thus connecting the four independent H-shaped columns to form a composite column. The four H-shaped columns collectively provide the steel frame building with load-bearing capacity, significantly increasing the column's bearing capacity compared to four H-shaped columns acting individually. Therefore, for the same load-bearing capacity, the column's cross-sectional dimensions are reduced, saving steel and reducing manufacturing costs. Furthermore, the interconnection of the four independent H-shaped columns into a composite column significantly enhances the overall structure's seismic resistance. Furthermore, this modular steel frame structure is simple in construction, with easy-to-manufacture connectors. Bolted connections between the H-shaped columns facilitate on-site connection.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] Example 1

[0029] Reference Figures 1 to 5 As shown, this embodiment provides a modular steel frame structure with combined columns, comprising:

[0030] A plurality of unit steel frames, each unit steel frame being composed of a plurality of H-shaped steel columns 1 and steel beams, wherein adjacent H-shaped steel columns 1 on the plurality of unit steel frames are spliced together to form a composite column;

[0031] A plurality of gusset plates 5 are arranged in parallel outside the outer flanges of the two adjacent H-shaped steel columns 1 on the left and right of the composite column. First bolts 6 are provided at both ends of the gusset plates 5 corresponding to the two adjacent H-shaped steel columns 1 on the left and right. The first bolts 6 connect the gusset plates 5 with the two adjacent H-shaped steel columns 1 on the left and right.

[0032] The flanges of two adjacent H-shaped steel columns 1 in the composite column are connected to each other by a plurality of second bolts 7 arranged in parallel.

[0033] The four H-shaped steel columns 1, each derived from four different unit steel frames, are abutted against each other. Two adjacent H-shaped steel columns 1 on the left and right are connected and secured by several parallel tie plates 5. One end of the tie plate 5 is bolted to the left H-shaped steel column 1 via a first bolt 6, and the other end is bolted to the right H-shaped steel column 1 via another first bolt 6, thus connecting the two adjacent H-shaped steel columns 1 together. Two adjacent H-shaped steel columns 1 on the front and back are bolted together via second bolts 7 at their contacting flanges. This interconnects the four independent H-shaped steel columns 1, forming a composite column. The four H-shaped steel columns 1 collectively provide load-bearing capacity for the steel frame building, significantly increasing the column's load-bearing capacity compared to four H-shaped steel columns 1 acting individually. This reduces the cross-sectional dimensions of the columns, saving steel and lowering manufacturing costs while maintaining the same load-bearing capacity. Furthermore, the interconnection of the four independent H-shaped steel columns 1 into a composite column significantly enhances the overall structure's seismic resistance. Furthermore, this modular steel frame structure is simple in construction and easy to manufacture. The bolted connections between the H-shaped steel columns 1 facilitate on-site connection.

[0034] To further optimize the solution, mounting bolt holes 8 are provided at both ends of the gusset plate 5; a number of outer flange bolt holes are provided on the outer flange of the H-shaped steel column 1 corresponding to the mounting bolt holes 8, and the outer flange bolt holes and the mounting bolt holes 8 are both large circular holes. The first bolt 6 passes through the mounting bolt hole 8 and the outer flange bolt hole to connect the gusset plate 5 and the H-shaped steel column 1.

[0035] The large circular holes used for the mounting bolt holes 8 and the outer flange bolt holes are to compensate for manufacturing errors so as to enable smooth installation during on-site assembly.

[0036] According to a further optimization scheme, the width of the gusset plate 5 is the sum of the widths of the outer flanges of the two adjacent H-shaped steel columns 1 on the left and right.

[0037] The width of the gusset plate 5 is greater than the sum of the widths of the outer flanges of the two adjacent H-shaped steel columns 1 on the left and right, which can make the connection between the gusset plate 5 and the H-shaped steel column 1 by the first bolt 6 more stable and avoid bending and deformation of the edge of the gusset plate 5 under stress.

[0038] To further optimize the solution, inner flange bolt holes are opened at the flanges of the two adjacent H-shaped steel columns 1 that contact each other. The inner flange bolt holes are circular holes, and the second bolts 7 pass through the corresponding two inner flange bolt holes to connect the two adjacent H-shaped steel columns 1.

[0039] Because the two H-shaped steel flange plates cannot be moved as easily as the gusset plate 5, it is necessary to consider aligning multiple parallel inner flange bolt holes. Therefore, the inner flange bolt holes opened at the flanges where the two H-shaped steel columns 1 contact each other are large circular holes to facilitate the installation of the second bolt 7.

[0040] To further optimize the solution, the second bolt 7 is clearance-matched with the inner flange bolt hole.

[0041] The clearance fit between the second bolt 7 and the inner flange bolt hole is conducive to compensating for the error generated during drilling.

[0042] Example 2

[0043] Reference Figure 1 and Figure 6-8 As shown, the modular steel frame structure of the combined columns of this embodiment differs from that of embodiment 1 only in that this embodiment 2 is a combined column formed by combining two H-shaped steel columns 1, which is commonly found at the edge unit steel frame connection of modular steel frame buildings;

[0044] In this embodiment, both sides of the two H-shaped steel columns are connected by using the tie plates 5 and the first bolts 6 , and there are no inner flange bolt holes and second bolts 7 .
