[0001] This utility model relates to the field of foundation pit engineering technology, and in particular to a ring beam suspension structure. Background Technology

[0002] In urban renewal construction, foundation pit construction often faces challenges due to the complexity of the surrounding environment. Traditional servo-supported concrete construction requires the installation of columns under the inner ring beam, which not only increases construction costs but also occupies valuable construction space. Summary of the Invention

[0003] The purpose of this utility model is to address the shortcomings of the prior art by providing a ring beam suspension structure. This structure involves setting connecting ribs inside the inner ring beam and hooking the entire structure onto the support pier through these ribs. Furthermore, it uses suspension bars to effectively suspend the outer ring beam to the ground wall, providing the necessary vertical lifting and support force for the inner ring beam and avoiding the need for a column under the inner ring beam.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A ring beam suspension structure is provided for fixing an inner ring beam, an outer ring beam is provided on the outer side of the inner ring beam, and a diaphragm wall is provided on the outer side of the outer ring beam. The structure is characterized by including an inner and outer ring beam connecting structure and a diaphragm wall suspension structure.

[0014] Figure 3 This is a detailed view of the connecting structure of the connecting rib in this utility model. Detailed Implementation

[0015] The features of this utility model and other related features will be further described in detail below with reference to the accompanying drawings and embodiments, so as to facilitate the understanding of those skilled in the art:

[0016] like Figure 1-3 As shown in the figure, each of the markings represents: connecting rib 1, embedded steel plate 2, support 3, inner ring beam 4, embedded steel plate 5, diaphragm wall 6, outer ring beam 7, support 8, hanger 10, upper rib plate 11, and lower rib plate 12.

[0017] Example: Figures 1 to 3 As shown, the ring beam suspension structure in this embodiment is used to solve the problem of fixing the inner ring beam 4, especially to fix the inner ring beam 4 without setting up columns and ensure its structural strength and stability. In this embodiment, a support 8 is provided on the inner side of the inner ring beam 4, an outer ring beam 7 is provided on the outer side, and a diaphragm wall 6 is provided on the outer side of the outer ring beam 7.

[0018] The suspension structure of the inner ring beam 4 in this embodiment includes two parts. One part is the connection between the inner ring beam 4 and the outer ring beam 7 to connect the inner and outer ring beams to form an integral structure. The other part is the suspension connection structure that connects the inner ring beam 4 and the outer ring beam 7 to the underground continuous wall 6 to form an integral structure.

[0019] Specifically, a support 3 is provided on the inner side of the outer ring beam 7, adjacent to the inner ring beam 4, and the support 3 is cast integrally with the outer ring beam 7. In some cases, a groove may be provided on the upper surface of the support 3 for placing the upper rib plate 11 of the connecting rib 1.

[0020] A connecting rib 1 is embedded on the side of the inner ring beam 4 adjacent to the outer ring beam 7. The connecting rib 1 has an L-shaped structure, which includes an upper rib plate 11 and a lower rib plate 12. The lower rib plate 12 is embedded in the inner ring beam 4 simultaneously with the pouring of the inner ring beam 4. The upper rib plate 11 extends out of the top surface of the inner ring beam 4 and extends towards the outer ring beam 7. A pre-embedded steel plate 2 is provided on the surface of the support 3. The upper rib plate 11 is placed at the pre-embedded steel plate 2, which maintains the overall suspension of the inner ring beam 4 and the support.

[0021] In this embodiment, a pre-embedded steel plate 5 is provided on the side of the support 3 adjacent to the connecting rib 1, and a pre-embedded steel plate 5 is also provided on the corresponding side of the connecting rib 1. The pre-embedded steel plates 5 on both sides are connected to further improve the connection strength and stability between the support 3 and the connecting rib 1.

[0022] Hanging bars 10 are installed at the outer ring beam 7 and the inner ring beam 4, respectively. The other end of each hanging bar 10 is welded to the exposed steel reinforcement of the diaphragm wall 6 to form an integral structure. The hanging bars effectively suspend the inner ring beam 4 and the outer ring beam 7 to the diaphragm wall 6, ensuring the structural performance of both. In this embodiment, the portion of the hanging bar 10 inside the inner ring beam 4 or the outer ring beam 7 is a bent structure to improve the suspension effect.

[0023] In this embodiment, the material of the connecting rib 1 can be steel or precast concrete. Depending on the type of connecting rib 1, there are two construction methods, as detailed below:

[0024] When connecting rib 1 is a steel connecting rib, the main steps include the following:

[0025] 1) Locate and construct the underground continuous wall 6, set up formwork and construct the inner ring beam 4, outer ring beam 7, pier 3, and support 8.

[0026] 2) Set up embedded steel plates 2 and 5, connecting ribs 1 and lifting bars 10. Among them, the embedded steel plate 2 is set on the upper side of the pier 3, the lower rib plate 12 of the connecting rib 1 is embedded in the inner ring beam 4, the upper rib plate 11 of the connecting rib 1 is welded to the embedded steel plate 2 on the upper surface of the pier, and the lower end of the lifting bar 10 is anchored in the outer ring beam 7; pour concrete to form the inner ring beam 4, outer ring beam 7, support 8, pier 3 and other concrete beam and slab structures.

[0027] 3) Weld the upper end of the suspension rod 10 to the exposed steel reinforcement of the underground continuous wall 6 to apply tension to the outer ring beam 7.

[0028] 4) After the concrete beam-slab support structure is finally formed, the inner ring beam 4 and the support 8 are firmly connected to the pier 3 through the connecting rib 1. At the same time, using the hanger 10, the inner ring beam 4, the outer ring beam 7, and the support 8 are effectively suspended and fixed to the underground continuous wall 6, thereby achieving stable suspension of the entire ring beam structure. This design not only enhances the stability of the structure but also improves the overall load-bearing capacity.

[0029] When connecting rib 1 is a precast concrete connecting rib, the main steps include the following:

[0030] 1) Locate and construct the underground continuous wall 6, set up formwork and construct the inner ring beam 4, outer ring beam 7, pier 3, and support 8.

[0031] 2) When setting up the formwork for pier 3, a certain number of groove sections are reserved. Precast concrete connecting ribs 1 are placed in the groove sections, and concrete is poured to fill the gap between the upper rib 11 of the connecting rib and the groove section, and the upper rib 11 is bonded to pier 3. The lower rib 12 of the connecting rib is embedded in the inner ring beam 4;

[0032] 3) Install hanger bars 10. The lower rib plate 12 of the connecting rib 1 is embedded in the inner ring beam 8, and the lower end of the hanger bar 10 is anchored in the outer ring beam 7; pour concrete to form a concrete beam and slab structure including the inner ring beam 4, the outer ring beam 7, the support 8, and the pier 3.

[0033] 4) Weld the upper end of the suspension rod 10 to the exposed steel reinforcement of the underground continuous wall 6 to apply tension to the outer ring beam 7.

[0034] In this embodiment, the number of connecting ribs 1 should be dynamically calculated and designed based on the cross-sectional width of the pier 3 and the vertical load limit value borne by the supporting structure, so as to achieve the optimal reinforcement effect of the structure.

[0035] Although the above embodiments have described the concept and embodiments of the present invention in detail with reference to the accompanying drawings, those skilled in the art will recognize that various improvements and modifications can still be made to the present invention without departing from the scope of the claims, and therefore will not be elaborated here.
