Description

Technical Field

[0001] This utility model relates to the field of building structure technology, and more particularly to a prefabricated frame module and an interleaved stacking structure system. Background Technology

[0002] Existing prefabricated concrete building structures are formed by assembling prefabricated components such as slabs, beams, columns, and connection nodes on-site and then casting them into a structural whole. However, their degree of prefabrication is not high, the on-site workload is large, and they cannot fully utilize the advantages of industrialized construction. Modular structures, as an advanced stage of prefabricated buildings, have the advantages of rapid construction and high integration. The modules in existing modular structures are mainly steel modules or concrete modules. Prefabricated frame modular structures formed by steel-reinforced concrete beam-column components combine the advantages of both steel and concrete structures, offering high load-bearing capacity and low cost. Module connection nodes are a key part determining the performance of modular structures; their load-bearing capacity and ease of construction directly affect the safety and application range of the entire building. However, current connection node technologies still have some structural problems and shortcomings, requiring further research and improvement. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Please see Figure 1 As shown, this utility model relates to a prefabricated frame module 1, which includes a rectangular frame 10 and connecting nodes 20. The connecting nodes 20 are connected to the eight vertices of the frame 10, and two adjacent frames 10 are connected by staggered stacking through the connecting nodes 20.

[0026] Combination Figure 2 As shown, the frame 10 includes a concrete frame 16 and a steel frame 11, with the steel frame 11 correspondingly embedded within the concrete frame 16. Figure 3 and Figure 4 As shown, the steel frame 11 includes precast columns 12, precast beams 13, and reinforcing bars 14. The precast columns 12 and precast beams 13 are vertically connected at connection nodes 20, and the reinforcing bars 14 are arranged in a grid pattern covering the outer surface of the precast columns 12 or precast beams 13. The grid-like reinforcing bars 14 can greatly improve the load-bearing capacity and deformation performance of the frame 10, effectively suppress the formation and development of cracks during loading, and ensure the safety and integrity of the structure.

[0027] The reinforcing bars 14 include longitudinal reinforcing bars 141 and stirrups 142. The longitudinal reinforcing bars 141 run in the same direction as the precast column 12 or precast beam 13, and multiple longitudinal reinforcing bars 141 are arranged around the outer perimeter of the precast column 12 or precast beam 13. The stirrups 142 are wrapped around the outside of the longitudinal reinforcing bars 141 and tighten the multiple longitudinal reinforcing bars 141 to the precast column 12 or precast beam 13. The multiple stirrups 142 are evenly arranged along the extension direction of the longitudinal reinforcing bars 141. By connecting the stirrups 142 with the reinforcing bars 14, the contact area and contact resistance with the post-cast concrete are effectively increased, thereby improving the shear strength and seismic performance of the frame 10.

[0028] The precast column 12 is composed of two cross-shaped I-beams. The precast beam 13 is also an I-beam. The stable I-beam structure of the precast column 12 and precast beam 13 increases the contact area between the steel frame 11 and the concrete frame 16, enhances the enclosure of the steel frame 11 by the concrete frame 16, thereby improving the structural strength of the steel frame 11. This allows for a smaller cross-sectional dimension of the steel frame 11 under the same load requirements, which helps reduce the amount of steel used in the frame 10 and improves the economic efficiency of the project.

[0029] The outer surface of the I-beam has a first stud 15 extending horizontally outward. The first stud 15 on the I-beam strengthens the synergy between the steel frame 11 and the post-cast concrete frame 16, further improving the overall performance of the precast frame module 1.

[0030] The connecting node 20 has a plug-in portion for vertical insertion, which consists of a C-shaped plug-in block 22 and a C-shaped plug-in cylinder 23. Specifically, the connecting node 20 includes a connecting plate 21, a C-shaped plug-in block 22, and a C-shaped plug-in cylinder 23, with the C-shaped plug-in block 22 and C-shaped plug-in cylinder 23 connected relative to each other on the connecting plate 21. Both ends of the precast column 12 are connected to the connecting plates 21 of the two connecting nodes 20, and both ends of the precast beam 13 are connected to the C-shaped plug-in cylinders 23 of the two connecting nodes 20, respectively. When the two connecting nodes 20 are plugged in, the C-shaped plug-in block 22 is inserted into the C-shaped plug-in cylinder 23 to form a grouting space, and the two precast frame modules 1 are connected by grouting.

[0031] The outer wall of the C-shaped plug block 22 extends horizontally outward with second studs 24, and multiple second studs 24 are arranged in multiple vertical columns. The inner wall of the C-shaped plug cylinder 23 extends horizontally inward with third studs 25, and multiple third studs 25 are arranged in multiple vertical columns. After the two connecting nodes 20 are plugged in, the second studs 24 and third studs 25 are arranged horizontally and alternately. Because the grouting space is equipped with second studs 24 and third studs 25, the reliability of the connection between the two connecting nodes 20 is improved.

[0032] Please see Figure 5As shown, this utility model relates to an interlaced stacking structure system, including multiple prefabricated frame modules 1, which are interlaced and stacked through connecting nodes 20 to form a multi-layer rectangular main structure.

[0033] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
