[0002] To ensure the safety of underground structures and the surrounding environment of the foundation pit, protective measures such as support and reinforcement are required for the sidewalls and surrounding area of ​​the pit. Prefabricated steel composite foundation pit support technology offers advantages such as convenient installation, recyclable materials, and more environmentally friendly use, making it a mainstream foundation pit support technology. A prefabricated steel composite foundation pit support system typically includes retaining piles surrounding the edge of the foundation pit, walers located inside the retaining piles, and several support beams positioned between the waler beams. Inside the foundation pit, the support beams are usually supported by columns and crossbeams.

Existing technology typically involves welding the crossbeams to the lower surface of the walers. However, in this existing technology, the welded connection between the crossbeams and walers is difficult to disassemble and reassemble, difficult to recycle, and the welding alters the structural strength and stress distribution of the walers; furthermore, adjusting the position of the crossbeams after welding to the walers is difficult. Therefore, the existing technology needs improvement. Summary of the Invention

[0020] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with this application; they are merely examples of apparatuses and methods consistent with some aspects of this application.

[0021] The following detailed description, with reference to the accompanying drawings, describes a sawtooth-type waler component for foundation pit protection according to this application. Unless otherwise specified, features in the following embodiments can be combined with each other.

[0022] Specific Implementation Example 1: Please refer to... Figures 1 to 3 As shown, this application provides a connection node structure for a lifting beam 30, used to connect a crossbeam 40 and a steel waler 20. The steel waler 20 is connected to retaining piles 80 via force transmission components 10, and the retaining piles 80 are distributed around the perimeter of the foundation pit. The steel waler 20 is a rigid elongated structure, and its length direction is perpendicular to the length direction of the retaining piles 80.

[0023] The force transmission component 10 is fixed to the retaining pile 80 and is made of steel. Optionally, the force transmission component 10 is welded to the retaining pile 80 to fix the two into a single unit. The welding position of the force transmission component 10 on the retaining pile 80 can be flexibly adjusted to accommodate different installation height requirements of the crossbeam 40. Optionally, the force transmission component 10 is embedded in a concrete beam, which is connected to the retaining pile 80, with the surface of the force transmission component 10 exposed on the surface of the concrete beam.

[0024] In an optional embodiment, the force transmission component 10 includes a welded component 11 and a mounting plate 12 fixed to the welded component 11. The mounting plate 12 is provided with spaced-apart fixing holes. One end of the welded component 11 is welded to the retaining pile 80, such that the mounting plate 12 and the retaining pile 80 are located at opposite ends of the welded component 11. The steel waler 20 is locked to the mounting plate 12 by fasteners 50. Optionally, the cross-section of the welded component 11 is configured as a cross-shaped structure, a U-shaped structure, or an H-shaped structure.

[0025] The steel waler 20 is detachably connected to the force transmission member 10 via fasteners 50, and the steel waler 20 is fixed to the force transmission member 10 so that the two are installed and fixedly connected as a whole. Each steel waler 20 connects to two or more force transmission members 10, realizing multi-point connection and high installation structural strength.

[0026] The lifting beam 30 is detachably connected to the steel waler 20 via fasteners 50. The lifting beam 30 is used to lift and connect the crossbeam 40. The lifting beam 30 is a rigid structural component, and its installation position can be adjusted by moving along the length of the steel waler 20, improving the ease of adjustment. The lifting beam 30 can be adjusted along the length of the steel waler 20 to meet different support requirements, making operation convenient. Furthermore, the crossbeam 40 extends from the lifting beam 30 to below the steel waler 20, improving the connection stability between the lifting beam 30 and the crossbeam 40. The crossbeam 40 extends below the steel waler 20 so that the crossbeam 40 and the steel waler 20 provide mutual leverage support, making the overall structure more stable.

[0027] In one embodiment, the steel waler 20 includes an H-beam 21, which has a first side plate 211 and a second side plate 212, a web connecting the first side plate 211 and the second side plate 212, and a reinforcing plate 22. The first side plate 211 and the second side plate 212 are parallel to each other, and the web is located at the middle of the first side plate 211 and the second side plate 212. The reinforcing plate 22 connects the first side plate 211, the web, and the second side plate 212 to form a three-sided reinforced structure.

[0028] The H-beam 21 has parallel first side plates 211 and second side plates 212, each with through mounting holes 23 for mounting fasteners 50. The first side plate 211 of the H-beam 21 is attached to the force transmission member 10 and locked to it by fasteners 50. The lifting beam 30 is connected to the second side plate 212 of the H-beam 21. The first side plate 211 is attached to the mounting plate of the force transmission member 10 and fixedly connected by fasteners 50. Optionally, the mounting holes 23 and the fixing holes are locked by the fasteners 50, facilitating installation. The fasteners 50 are configured as high-strength bolt assemblies.

[0029] Furthermore, the mounting holes 23 are arranged in multiple sets at intervals along the length of the second side plate 212. The lifting beam 30 is selected to be connected and fixed to one of the multiple sets of mounting holes 23 along the length of the second side plate 212. The positions of the mounting holes 23 are adapted to the installation position of the lifting beam 30 to facilitate flexible adjustment of the installation position of the lifting beam 30.

[0030] In one embodiment, the steel waler 20 includes two walers, adjacent to each other, connected by fasteners 50. The lifting beam 30 is connected to one of the steel walers 20, and the other steel waler 20 is connected to the force transmission member 10. Two steel walers 20 are provided and connected to each other to adjust the structural strength. Having two steel walers 20 not only improves the connection strength but also allows for adjustment of the installation position of the crossbeam 40. Optionally, adjacent steel walers 20 are locked together by fasteners 50 for easy assembly and adjustment.

[0031] Please refer to Figures 1 to 3 As shown, the lifting beam 30 is used to connect the crossbeam 40. The lifting beam 30 includes a steel section 31 and a bottom sealing plate 32 fixed to one end face of the steel section 31. The steel section 31 has two flanges, namely a first flange 311 and a second flange 312. The bottom sealing plate 32 is connected to one end of the two flanges 311 and 312. The two flanges 311 and 312 and the bottom sealing plate 32 form a U-shaped structure. One of the two flanges 311 and 312 is connected to the steel waler 20 by a fastener 50, thereby connecting the lifting beam 30 to the steel waler 20. The bottom sealing plate 32 has spaced-apart lifting holes 34, through which the fasteners 50 pass and connect to the crossbeam 40. Further, the lifting beam 30 also includes a top sealing plate 33 fixed to the other end face of the steel section 31, and the top sealing plate 33 is flush with the surface of the steel waler 20. The top sealing plate 33 and the bottom sealing plate 32 are arranged opposite to each other. The top sealing plate 33 is also provided with lifting holes. The lifting holes on the top sealing plate 33 and the lifting holes 34 on the bottom sealing plate 32 are arranged one-to-one. In this way, when installing the lifting beam 30, there is no need to distinguish between the top and bottom, which improves the convenience of assembly.

[0032] The steel section 31 has high structural strength and dimensional stability, and the bottom sealing plate 32 is fixed to the steel section 31. The steel section 31 is configured in an H-shape, meaning it also includes a web connecting the two flange plates 311 and 312, the top sealing plate, and the bottom sealing plate. The lifting beam 30 also includes reinforcing ribs that intersect perpendicularly with the web and connect the top sealing plate 33 and the bottom sealing plate 32, thus improving the structural strength of the lifting beam 30. The side of the steel section 31 is attached to the second side plate 212 of the steel waler 20 and connected by fasteners 50. The bottom sealing plate 32 is located at the bottom of the steel section 31 and is perpendicular to the second side plate 212 to facilitate adjustment of the installation angle of the crossbeam 40.

[0033] To improve the stability of the connection node structure of the lifting beam 30, the connection node structure further includes a corbel member. The corbel member includes a horizontal angle steel 60 fixedly connected to the retaining pile 80 and a diagonal bracing angle steel 70 connected to the horizontal angle steel 60. The diagonal bracing angle steel 70 is inclinedly connected between the retaining pile 80 and the horizontal angle steel 60. The steel waler 20 is erected on the horizontal angle steel 60. The horizontal angle steel 60 extends from the retaining pile 80 towards the steel waler 20 to support the steel waler 20, and subsequently supports the crossbeam 40 and the structure connected to the crossbeam 40. The diagonal bracing angle steel 70 and the horizontal angle steel 60 form a triangular support structure, resulting in good structural stability.
