Description

Technical Field

[0001] The invention relates to the technical field of construction, and in particular to a modular assembled steel structure composite column and an assembly system. Background Art

[0002] Modular prefabricated steel structure buildings use single modules as the basic construction units. The processing and manufacturing, including the processing and manufacturing of load-bearing components, enclosing components, etc. and decoration and decoration, are completed in the factory. The unit modules are then transported to the construction site, hoisted and spliced ​​together to complete the construction of the entire building.

[0003] For modular prefabricated steel structure buildings, modular units generally use steel pipe columns, and the splicing between modules mainly relies on the beam-column node connection at the corners; when a module needs to be spliced ​​with a horizontally adjacent module, the adjacent module steel pipe columns are close to each other, but are independent of each other when subjected to force, which will cause a waste of column materials, and the space occupied by multiple columns together is too large. If the connected module columns of horizontally adjacent modules are formed into composite columns, it can not only save steel column materials, but also reduce the space occupied by multiple module columns together, thereby increasing the indoor area of ​​the building. Therefore, we propose a modular prefabricated steel structure composite column and assembly system. Summary of the invention

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0032] Example 1

[0033] Reference Figure 1 to Figure 7 , which is the first embodiment of the present invention, and this embodiment provides a modular assembled steel structure composite column, a steel pipe column 100, which is composed of a plurality of steel frames 101, and the steel frames 101 are arranged in an L-shape or a U-shape, and a accommodating space M is formed inside the steel pipe column 100; and, a stirrup cage 200 is arranged inside the accommodating space M.

[0034] like Figure 2 As shown, the steel frame 101 is set in an L shape; Figure 3 As shown, the steel frame 101 is configured in a U shape.

[0035] When a plurality of steel frames 101 are assembled into a steel pipe column 100, a receiving space M is formed on the steel pipe column 100; wherein the steel pipe column 100 can be Figure 4 As shown, it is composed of two U-shaped steel frames 101, or the steel pipe column 100 can be as Figure 5 As shown, it is composed of four L-shaped steel frames 101, or the steel pipe column 100 can be composed of Figure 6 As shown, it is composed of two L-shaped steel frames 101 and one U-shaped steel frame 101 to facilitate transportation and assembly.

[0036] Preferably, a steel bar tie rod 102 is connected between two adjacent sides of the inner wall of the steel frame 101; and a plurality of steel bar tie rods 102 are arranged at equal intervals along the height direction of the accommodating space M.

[0037] It is additionally noted that the steel bar tie rod 102 on the L-shaped steel frame 101 is arranged as follows: Figure 2 As shown, the L-shaped steel frame 101 can be surrounded into a triangle by the steel bar tie rod 102; the steel bar tie rod 102 on the U-shaped steel frame 101 is arranged as follows Figure 3 As shown, two steel bar tie rods 102 are arranged on the U-shaped steel frame 101 .

[0038] Preferably, when a plurality of steel frames 101 are combined into a steel pipe column 100 , four steel bar tension rods 102 are provided on a single cross section of the steel pipe column 100 and form an activity space N.

[0039] like Figures 4 to 6As shown, after the steel pipe column 100 is assembled, four steel bar tie rods 102 are provided in a single cross-sectional direction of the steel pipe column 100 , and an activity space N is enclosed by the four steel bar tie rods 102 .

[0040] Preferably, the stirrup cage 200 can pass through the activity space N.

[0041] When the stirrup cage 200 is placed in a position concentric with the frame formed by the four steel pipe columns 100 and is placed in parallel with each other in a one-to-one correspondence, the size of the movable space N needs to be set so that the stirrup cage 200 can pass freely.

[0042] When a module needs to be spliced ​​with a horizontally adjacent module, such as Figure 1 As shown, adjacent module steel pipe columns are close to each other, but are independent of each other when subjected to force, resulting in a waste of column materials, and a plurality of columns together occupy too much space; therefore, the combined column designed by the present invention can not only save steel column materials, but also reduce the space occupied by a plurality of module columns together, thereby increasing the indoor area of ​​the building, compared with the prior art.

[0043] Example 2

[0044] Reference Figures 1 to 8 , Fig.10 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs in that the stirrup cage 200 is welded by a plurality of stirrups 201 and longitudinal structural steel bars 202 that are arranged in parallel and at equal distances, and the number and spacing of the stirrups 201 are the same as those of the steel bar tie rods 102.

[0045] Stirrup cage 200 Figure 7 As shown, preferably four longitudinal structural steel bars 202 are provided, and a plurality of stirrups 201 are welded together through the four longitudinal structural steel bars 202 to form a stirrup cage 200 .

[0046] Preferably, after the stirrup cage 200 passes through the movable space N, the steel bar tie rods 102 and the stirrups 201 are arranged one by one in an up-and-down staggered manner with a distance close to 0.

[0047] It should be noted that if Figure 8 As shown, the number and spacing of stirrups 201 are the same as the number and spacing of the steel bar tie rods 102 on the steel section, except that they need to be slightly staggered in space, and after the stirrup cage 200 is rotated, each stirrup 201 can be placed on the steel bar tie rod 102 at the corresponding position.

[0048] Preferably, by rotating the stirrup cage 200 , the stirrups 201 and the steel bar tie rods 102 can intersect to form an installation area Q.

[0049] When the stirrup cage 200 rotates, an installation area Q is formed. The installation area Q preferably has four. The installation area Q is as follows: Figure 6 The corners of the stirrups 201 may intersect with the steel bar tie rod 102, and form a space into which the longitudinal force-bearing steel bars 300 may be inserted, that is, the installation area Q.

[0050] Preferably, the longitudinal stress-bearing steel bars 300 are inserted into the installation area Q.

[0051] Preferably, cement-based material is poured into the accommodating space M to connect the stirrups 201, the steel bar tie rods 102 and the longitudinal force-bearing steel bars 300 to each other.

[0052] The main steel components of the composite column include an L-shaped steel frame 101 or a U-shaped steel frame 101, a steel bar tie rod 102, a stirrup cage 200 and longitudinal stress-bearing steel bars 300, and finally cement-based materials are poured into the internal space formed by the steel section.

[0053] Furthermore, compared with the previous scheme, which is a single section, the bending inertia moment of this scheme is linearly superimposed. After forming an integral section, the bending inertia moment needs to be recalculated and is greater than the linear superposition. On this basis, the column can be made thinner, and the column end bending moment formed by resisting the lateral force can be made smaller because the combined section can achieve the same effect as multiple single sections; thereby, the adjacent independently stressed steel pipe columns of the relevant construction unit modules are replaced and transformed to form a combined column that bears common stress, which can achieve the purpose of reducing the use of steel, reducing the space occupied by columns and improving the structure's resistance to lateral forces.

[0054] In summary, the modular assembled unit steel column composed of the L-shaped or U-shaped steel frame 101 and the steel bar tie rod 102 can save a lot of steel compared to the square steel tube column with the same cross-section; and a plurality of modular unit columns form a composite column, which has a higher stress-bearing performance under the same cross-sectional size, and a smaller cross-section can be used under the same stress-bearing performance requirements, further saving a lot of steel; the internal hoop cage 200 and the steel bar tie rod 102 are connected by the longitudinal stress-bearing steel bars 300 and the poured cement-based material, ensuring that the composite column has excellent stress-bearing performance, making the composite column more suitable for high-rise modular assembled steel structure buildings.

[0055] Example 3

[0056] Reference Figures 1 to 10 , which is the third embodiment of the present invention, is based on the previous embodiment, but differs in that this embodiment proposes an assembly system.

[0057] Specifically, the steel pipe column 100 is composed of two U-shaped steel frames 101 or four L-shaped steel frames 101 or one U-shaped steel frame and two L-shaped steel frames 101. The stirrup cage 200 is placed inside the steel pipe column 100 and rotated, and the longitudinal stress-bearing steel bars 300 are inserted and poured with cement to form a composite column.

[0058] In summary, by combining the steel frame 101 to form the steel pipe column 100, the stirrup cage 200 is passed through the interior of the steel pipe 100 and then selected, so that the stirrups 201 are placed one-to-one on the steel bar tie rod 102, the longitudinal stress-bearing steel bars 300 are inserted, and cement is poured in for connection to form a combined column. The overall assembly method is simple and convenient.
