Description

Technical Field

[0001] This invention relates to the field of building technology, and more specifically to a steel-concrete composite module for buildings. Background Technology

[0002] Currently, the types of connection nodes applicable to lightweight steel-concrete composite modular structures are relatively limited. In modular structures containing L-shaped irregular columns, existing node technologies are particularly scarce, failing to meet the specific requirements of such irregularly shaped columns in terms of force transfer, structural coordination, and ease of construction. Furthermore, existing node designs often focus on connections between upper and lower module columns, commonly using insert-type connectors for vertical connection. However, the node area where four adjacent modules intersect on the same floor often lacks effective connections and overall reinforcement measures, resulting in weak stiffness and insufficient collaborative load-bearing capacity in this area, affecting the overall structural integrity and seismic performance.

[0003] On the other hand, traditional modular structural nodes often rely on extensive welding or require numerous high-strength bolts during on-site construction. This not only demands ample operating space but also increases the difficulty of on-site construction and raises quality control risks. Particularly in the central column area within the module, the narrow construction space further restricts worker operation, impacting construction efficiency and connection quality. Therefore, current technology lacks a column module connection structure that is structurally sound, easy to install, highly efficient, economical, and capable of balancing connections between upper and lower layers as well as overall collaborative work between modules on the same floor. This hinders the application and development of light steel-concrete composite modular systems in a wider range of scenarios. Summary of the Invention

[0004] Therefore, the present invention provides a steel-concrete composite module for buildings to solve the above-mentioned problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] According to a first aspect of the present invention, a steel-concrete composite module for a building includes an upper column module, a connecting module, a lower column module, and cast-in-place concrete. The upper column module contains an upper column filler, and the lower column module contains a lower column filler.

[0016] Furthermore, the upper half of the connecting pipe is provided with multiple sets of the stud assemblies, and the lower half of the connecting pipe is provided with multiple connecting hole assemblies. The multiple connecting hole assemblies are arranged sequentially along the length direction of the connecting pipe. Each connecting hole assembly includes four through holes.

[0043] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Example 1

[0045] like Figures 1 to 9 As shown, a steel-concrete composite module for a building in a first aspect embodiment of the present invention includes an upper column module 1, a connecting module 2, a lower column module 3, and cast-in-place concrete 6. The upper column module 1 and the lower column module 3 are both prefabricated modular components. The upper column module 1 is provided with an upper column filler 9, and the lower column module 3 is provided with a lower column filler 19. The bottom end of the upper column module 1 is connected to the top end of the lower column module 3. The connecting module 2 and the cast-in-place concrete 6 are both disposed between the upper column module 1 and the lower column module 3, and the main body of the connecting module 2 is located within the cast-in-place concrete 6.

[0046] The connecting module 2 is a key component for enhancing the connection between the upper and lower columns. The connecting module 2 includes an angle steel module 5 and a connecting assembly 7. The connecting assembly 7 includes a first connecting plate 15 and multiple connecting pipes 13. The first connecting plate 15 is horizontally positioned between the upper column module 1 and the lower column module 3, serving as a positioning and support base for the connecting pipes 13. The connecting pipes 13 are vertically positioned, with multiple connecting pipes 13 inserted into the first connecting plate 15. The top and bottom ends of the connecting pipes 13 extend above and below the first connecting plate 15, respectively, thus simultaneously embedding into the upper and lower prefabricated column modules. Multiple stud assemblies are provided on the connecting pipes 13, sequentially arranged along the length of the connecting pipe 13 on its outer side wall, forming multiple shear anchor points for enhanced shear resistance. Each stud assembly includes multiple studs 14, which are arranged in a ring along the axis of the connecting pipe 13. Specifically, as shown... Figure 7 and Figure 8 As shown, the connecting pipe 13 is a square pipe, and each stud assembly includes four studs 14. The four studs 14 are respectively arranged on the four sides of the connecting pipe 13. The connecting pipe 13 is mounted on the first connecting plate 15 using the studs 14. For ease of installation, the studs 14 of the lower half of the connecting pipe 13 can be detachably connected to the connecting pipe 13, for example, by threaded connection.

[0047] In this embodiment, it should be noted that, as Figure 4 As shown, the upper column module 1 includes four upper columns 8, each with an L-shaped cross-section. The four upper columns 8 together form a column structure with a cross-shaped cross-section. The upper column 8 is filled with an upper column filler 9, which is made of polystyrene particle concrete. While ensuring the strength of the component, it has the characteristics of low density, light weight, and excellent thermal insulation performance, meeting the requirements of building energy conservation. The bottom of each upper column 8 is provided with a first receiving cavity 10. The bottom and sides of the first receiving cavity 10 are open to accommodate the upper part of the connecting module 2 and to pour concrete.

[0048] like Figure 9As shown, the lower column module 3 includes multiple lower columns, each comprising a longitudinal column, a first transverse column, and a second transverse column. The longitudinal column is vertically positioned, while the first and second transverse columns are horizontally positioned. One end of the first transverse column and the top of the second transverse column are connected to the top of the longitudinal column, and the first and second transverse columns are perpendicular to each other. This design allows the lower column module 3 to not only serve as a vertical load-bearing column, but its transverse extension also facilitates connection with horizontal beams and other structural components of the building. The longitudinal column, the first transverse column, and the second transverse column are all equipped with lower column filler 19. The lower column filler 19 is made of polystyrene particle concrete, which has a low density and effectively ensures overall strength and thermal insulation performance. The top of the longitudinal column is equipped with a second receiving cavity 20, such as... Figure 9 As shown, the second receiving cavity 20 is located above the connection point of the first transverse column, the second transverse column and the longitudinal column. The top and sides of the second receiving cavity 20 are open. The first receiving cavity 10 and the second receiving cavity 20 are arranged corresponding to each other. After assembly, the first receiving cavity 10 and the second receiving cavity 20 are connected to each other to form the receiving cavity of the connecting component 7 and the cast-in-place concrete 6.

[0049] Specifically, such as Figure 9 As shown, the lower column module 3 is composed of two first lower columns 17 and two second lower columns 18 arranged in a mirror symmetrical manner. The first lower columns 17 and the second lower columns 18 have complementary shapes and together form a column structure with a cross-shaped cross section, which matches the cross-sectional shape of the upper column module 1.

[0050] Furthermore, such as Figure 7 and Figure 8 As shown, the first connecting plate 15 is cross-shaped and has multiple first connecting holes 16. The first connecting holes 16 are square holes and match the connecting tube 13 to ensure that the connecting tube 13 can be stably inserted and positioned.

[0051] like Figure 5 As shown, the angle steel module 5 includes multiple angle steel components, each including an upper angle steel plate 11 and a lower angle steel plate 12. The upper angle steel plate 11 is welded or fixed to the outer opening edge of the first receiving cavity 10 of the upper column module 1 by other means, while the lower angle steel plate 12 is fixed to the outer opening edge of the second receiving cavity 20 of the lower column module 3. A vertically upward pouring end pipe 4 is also welded to the top of the upper angle steel plate 11, which passes through the upper angle steel plate 11 and serves as the inlet for subsequent concrete pouring. The upper angle steel plate 11 and the inner wall of the first receiving cavity 10, and the lower angle steel plate 12 and the inner wall of the second receiving cavity 20 respectively form temporary pouring cavity templates.

[0052] The specific assembly steps for the entire module are as follows:

[0053] Step 1: First, hoist the lower column module 3 on site. Use lifting equipment to hoist the two first lower columns 17 and the two second lower columns 18 into place and assemble them into a complete lower column module 3 on site.

[0054] Step 2: Insert the lower end of the assembled connecting component 7 into the mounting cavity at the top of the lower column module 3.

[0055] Step 3: Hoist the upper column module 1 and insert the mounting cavity at the bottom of the upper column module 1 into the top of the connecting component 7.

[0056] Step 4: Install angle steel module 5. Install the upper angle steel plate 11 and the lower angle steel plate 12 to the outer openings of the first receiving cavity 10 and the second receiving cavity 20 respectively, and reliably fix them to the upper and lower column modules by welding or other methods to form a closed casting cavity side template.

[0057] Step 5: Pour cast-in-place concrete 6 into the cavity formed by the angle steel module and the upper and lower column housings through the pouring end pipe 4 on the upper angle steel plate 11. The concrete fills the space around the connecting pipe 13, covers all the studs, and connects the upper and lower column modules into one unit through the wet joint. After the concrete reaches the design strength and is cured, a stable column module node connection is formed.

[0058] The technical effects achieved in this embodiment are as follows: Through the coordinated work of the connecting module 2 (especially the connecting pipe 13 with multiple rows of studs) and the cast-in-place concrete 6, a rigid connection node with high strength and good ductility is formed between the upper and lower precast column modules, effectively transmitting axial force, bending moment, and shear force, and significantly improving the integrity and seismic shear resistance of the modular column. The polystyrene particle concrete filling inside the upper and lower column modules ensures structural strength while giving the column good thermal insulation performance, realizing integrated structural insulation. The entire system adopts a construction method that combines modular prefabrication, on-site dry assembly, and partial wet work (node ​​pouring), which greatly reduces the amount of wet work such as on-site formwork, rebar tying, and overall concrete pouring. The construction is simple and quick, the installation efficiency is high, and the project quality is easy to control, which is in line with the development direction of building industrialization.

[0059] Example 2

[0060] like Figures 10 to 17 As shown, another steel-concrete composite module for buildings provided in this embodiment, compared with embodiment 1, has a core improvement in the construction of the connecting pipe 13 in the connecting module 2 and its additional connection method with the lower column module 3, which aims to achieve higher connection strength and structural integrity. The building column module includes an upper column module 1, a connecting module 2, a lower column module 3 and cast-in-place concrete 6. The upper column module 1 is provided with an upper column filler 9, and the lower column module 3 is provided with a lower column filler 19. The bottom end of the upper column module 1 is connected to the top end of the lower column module 3.

[0061] Both the connecting module 2 and the cast-in-place concrete 6 are located between the upper column module 1 and the lower column module 3, and the main body of the connecting module 2 is located inside the cast-in-place concrete 6.

[0062] like Figure 15 and Figure 16 As shown, unlike Embodiment 1, the connecting pipe 13 in this embodiment adopts a differentiated design in different regions: on the outer wall of its upper half (the part inserted into the upper column module 1), multiple sets of stud assemblies are arranged at intervals along the length direction, each set including four studs 14 arranged in a ring to enhance the anchoring with the concrete of the upper column node area; on the pipe wall of its lower half (the part inserted into the lower column module 3), multiple sets of connecting hole assemblies are opened at intervals along the length direction, each set of connecting hole assemblies including four through holes 22 distributed in a ring array, these through holes 22 completely penetrate the pipe wall of the connecting pipe 13.

[0063] In this embodiment, it should be noted that, as Figure 13 As shown, the upper column module 1 is constructed in the same way as in embodiment 1, consisting of four L-shaped upper columns 8 arranged to form a cross-shaped cross section, filled with polystyrene particle concrete, and a first receiving cavity 10 at the bottom.

[0064] like Figure 17 As shown, the basic structure of the lower column module 3 is similar to that of Embodiment 1. Specifically, the column module 3 is assembled from two first lower columns 17 and two second lower columns 18 to form a cross-shaped cross-section column, which is filled with polystyrene particle concrete. The key difference is that in this embodiment, the position of the second receiving cavity 20 at the top of the longitudinal column is set deeper, directly inside the T-shaped node where the first transverse column, the second transverse column, and the longitudinal column intersect. This design makes the connection of the node area more core and concentrated, and the top and sides of the second receiving cavity 20 are also open.

[0065] Furthermore, such as Figure 15 and Figure 16 As shown, the main structure of the first connecting plate 15 and the angle steel module 5 is basically the same as that in Embodiment 1. Specifically, the first connecting plate 15 is cross-shaped, and the first connecting plate 15 is provided with a plurality of first connecting holes 16. The first connecting holes 16 are square holes, and the first connecting holes 16 are matched with the connecting pipe 13.

[0066] The angle steel module 5 includes multiple angle steel components, each including an upper angle steel plate 11 and a lower angle steel plate 12. The upper angle steel plate 11 is provided with a casting end pipe 4, which is located at the top of the upper angle steel plate 11 and penetrates through the upper angle steel plate 11. Each first receiving cavity 10 is provided with an upper angle steel plate 11, and each second receiving cavity 20 is provided with a lower angle steel plate 12. The upper angle steel plate 11 and the lower angle steel plate 12 form casting cavities with the first receiving cavity 10 and the second receiving cavity 20, respectively.

[0067] like Figure 15 and Figure 16 As shown, another key difference in this embodiment is that the connecting assembly 7 also includes bolts 21 and a second connecting plate 23, and there are multiple bolts 21 and multiple connecting plates 23; the lower corner steel plate 12 is provided with a third connecting hole, and the bolts 21, the third connecting hole and the through hole 22 are matched with each other; the second connecting plate 23 is L-shaped, and the second connecting plate 23 is horizontally arranged in the second receiving cavity 20, and the second connecting plate 23 is provided with multiple second connecting holes 24, and the second connecting holes 24 are matched with the connecting pipe 13;

[0068] During installation, the lower half of the connecting pipe 13 passes through the second connecting hole 24 of the second connecting plate 23. Then, the bolt 21 is inserted horizontally, passing sequentially through the third connecting hole of the lower corner steel plate 12 on one side, the corresponding through hole 22 on the lower column component and its internal connecting pipe 13 on that side, and the corresponding through hole 22 on the adjacent lower column component and its internal connecting pipe 13 on the other side. Finally, it exits from the lower corner steel plate 12 on the other side and is tightened. In this way, the bolt 21 acts like a "lateral reinforcing rib," tightly connecting and locking the two adjacent lower columns, the internal connecting pipe 13, and the externally wrapped lower corner steel plate 12 together, forming a highly integrated rigid node area. This greatly improves the node's shear and torsional resistance in the horizontal direction.

[0069] The assembly method of the entire module is as follows:

[0070] Step 1: First, hoist the lower column module 3 on site, assemble the lower column module 3 using two first lower columns 17 and two second lower columns 18, and pre-weld and fix the second connecting plate 23 in the designed position inside the second receiving cavity 20.

[0071] Step 2: Insert the lower end of the assembled connecting component 7 into the mounting cavity at the top of the lower column module 3, so that the connecting pipe 13 passes through the second connecting plate 23.

[0072] Step 3: Hoist the upper column module 1 and fit the mounting cavity at the bottom of the upper column module 1 onto the top of the connecting component 7.

[0073] Step 4: Install angle steel module 5. The upper angle steel plate 11 and the lower angle steel plate 12 can be fixed by welding.

[0074] Step 5: Install bolts 21, using bolts 21 to pass through the two adjacent lower columns, the internal connecting pipe 13 and the external lower angle steel plate 12, and tighten them to connect them into a whole;

[0075] Step 6: Pour concrete using the pouring end pipe 4. Once the concrete has solidified and cured, the installation of the entire module is complete.

[0076] The technical effects achieved in this embodiment are as follows: Three key improvements further enhance structural performance: First, the lower half of the connecting pipe 13 is equipped with a through hole 22 and mates with bolts 21, providing a robust mechanical horizontal connection and significantly enhancing the shear and pull-out resistance of the node. Second, the second receiving cavity 20 is located inside the T-shaped node of the lower column, further strengthening the core area of ​​the node. Finally, the added second connecting plate 23 further enhances the positioning and support of the connecting pipe 13 within the lower column. These measures work together to make the connection of the entire column module more rigid, with higher safety redundancy and better overall structural integrity, making it particularly suitable for building components with higher node performance requirements or bearing greater loads; simultaneously, the advantages of modular and prefabricated construction are maintained.

[0077] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.

Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.
