[0002] In construction, the foundation pit support structure is a key factor in ensuring construction safety and stability. The design and construction of the support structure are particularly crucial in challenging environments, such as deep foundation pits or soft soil. Currently, steel sheet piles are widely used as a common temporary support structure for foundation pits, offering strong pullout resistance, load-bearing capacity, and ease of construction. Steel sheet piles are typically installed around the foundation pit, using their supporting properties to prevent soil collapse. To ensure overall stability and strength, existing steel sheet piles are welded to the sidewalls of the foundation pit. Crossbeams are placed on top of the supports, and a support structure similar to a circular tube, the same length as the foundation pit, is used to support the crossbeams.

DETAILED DESCRIPTION

[0037] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] In this document, the term "and / or" simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0039] like Figures 1 to 9As shown, the anti-collapse support structure of the building has multiple pile bodies 1 respectively arranged on the side walls on both sides of the foundation pit, and the number is reasonably increased according to the length of the foundation pit, and the multiple pile bodies 1 are arranged in two groups to support both sides of the foundation pit. The support adjustment component 3 is arranged on the pile body 1, and the support adjustment component 3 is used to carry the crossbeam 8. Connectors 10 are provided on both sides of the crossbeam 8. The connectors 10 are used to connect two adjacent crossbeams 8. The connectors 10 can be structures such as rivets, and are not specifically limited. The adjustment mechanism 4 is connected to the first support rod 5 and the second support rod 6. The relative extension distance of the first support rod 5 and the second support rod 6 is controlled by the adjustment mechanism 4 to ensure that the crossbeam 8 can be supported under foundation pits of different sizes, and there is no need to change the length of the crossbeam 8 by welding or cutting.

[0040] In actual use, the relative extension distance of the first support rod 5 and the second support rod 6 is changed by adjusting the mechanism 4, which can be adjusted according to the width of the construction pit. The user does not need to change the distance of the beam 8 by welding extension or cutting shortening. Compared with the traditional welding method, it is convenient for users to operate and saves construction time.

[0041] In this embodiment, external threads 401 are machined on the second support rod 6, while internal threads 403 are machined within the cavity 404 of the straight tube 402. The second support rod 6 is threadedly connected to the straight tube 402 via the external threads 401 and internal threads 403. The user can rotate the second support rod 6 to change the extension distance of the second support rod 6 relative to the straight tube 402, thereby controlling the relative position between the first support rod 5 and the second support rod 6 and allowing the second support rod 6 to be attached to one crossbeam 8. The first support rod 5 passes through the straight tube 402 and can slide relative to the straight tube 402 within the cavity 404, allowing the first support rod 5 to be attached to another crossbeam 8. This method allows the first support rod 5, the second support rod 6, and the adjustment mechanism 4 to support two crossbeams 8, thereby ensuring the stability of multiple pile bodies 1.

[0042] In actual use, the user can pull the first support rod 5 to fit it onto the crossbeam 8 on one side, and at the same time rotate the second support rod 6 on the other side to fine-tune the extension distance of the first support rod 5 and the second support rod 6. Compared with the traditional welding method, the self-adjusting method facilitates the adjustment of the relative extension length of the second support rod 6 and the first support rod 5 during the construction process, saving labor costs.

[0043] In this embodiment, the adjustment mechanism 4 further includes a plurality of slots 405 and a lever 406. Specifically, the plurality of slots 405 are machined on the exterior of the cylinder 402 and are evenly spaced on the cylinder 402. The lever 406 is connected to the first support rod 5 and can engage with the slots 405. When the lever 406 is engaged in the slots 405, relative movement between the first support rod 5 and the cylinder 402 is prevented, ensuring that the first support rod 5 remains stationary during construction, thereby maintaining support for the crossbeam 8. The lever 406 can be manually moved by the operator so that it enters the corresponding slot 405, thereby locking the position of the first support rod 5.

[0044] In actual use, after the user pulls out the first support rod 5 to the appropriate distance, they can rotate the lever 406. During this rotation, the lever 406 snaps into the corresponding slot 405 for fixation, allowing the first support rod 5 to be positioned. Simultaneously, the second support rod 6 can be rotated for fine-tuning, allowing the first and second support rods 5 and 6 to support the two crossbeams 8. Simultaneously, the pressure exerted on the two groups of piles 1 is directed toward the foundation pit, which also causes the lever 406 on the first support rod 5 to press against the inner side of the slot 405, preventing the lever 406 from separating from the slot 405. This simplifies the positioning process of the first support rod 5 and provides stable support during construction. Furthermore, the snap-fit ​​connection between the slot 405 and the lever 406 makes operation easier, allowing on-site construction workers to easily adjust and secure the first support rod 5, improving work efficiency and safety.

[0045] In this embodiment, the inner side of the arc-shaped support plate 7 is in contact with the outer wall surface of the first support rod 5 or the second support rod 6 to support the first support rod 5 or the second support rod 6 .

[0046] In actual use, the two arc-shaped support plates 7 can support the first support rod 5 or the second support rod 6. At the same time, the two arc-shaped support plates 7 do not affect the normal rotation of the first support rod 5 and the second support rod 6. The diameter of the arc-shaped support plate 7 is larger than the first support rod 5 and the second support rod 6, which makes it convenient for the user to place the first support rod 5 or the second support rod 6 inside the arc-shaped support plate 7 for positioning.

[0047] In this embodiment, bracket 301 is fitted against pile body 1 and is threadedly connected to screw 304. Screw 304 is rotatably connected to bracket 303. Rotating screw 304 causes bracket 303 to move synchronously, thereby adjusting the height of bracket 303. A stop plate 306 is fixedly connected to bracket 303 and passes through bracket 301, enabling up and down movement within the inner hole of bracket 301.

[0048] In actual use, since each pile body 1 is inserted into the ground at a different height, the user can rotate the screw 304, which in turn drives the bracket 303 to rotate and move it up and down. However, under the limit of the limit plate 306, the bracket 303 can only move up and down. The user can adjust the height of multiple brackets 303 in sequence so that the top surfaces of multiple brackets 303 are relatively flat, avoiding excessive tilt angles when placing the crossbeam 8 on multiple brackets 303, which may affect the support effect of multiple pile bodies 1.

[0049] In this embodiment, a handwheel 305 is connected to the screw 304. The user can rotate the handwheel 305 to drive the screw 304 to rotate, thereby adjusting the position of the bracket 303. The handwheel 305 makes it easier for the user to rotate the screw 304. The reinforcing rib 302 is connected to the bracket 301. The reinforcing rib serves to reinforce the bracket 301, improving its strength and stability and preventing deformation due to excessive load during adjustment.

[0050] In actual use, the reinforcing ribs 302 disperse the pressure on the bracket 301 by increasing the bearing area of ​​the bracket 301, thereby improving the stability and pressure resistance of the overall structure and ensuring that the bracket 301 can remain stable when the load changes.

[0051] In this embodiment, the positioning mechanism 9 includes a limiting member 901 and multiple groups of positioning blocks 902, wherein the limiting member 901 passes through the bracket 303 and can slide up and down relative to the bracket 303. The inner side of the limiting member 901 is in contact with the pile body 1, wherein the limiting member 901 is U-shaped and can only slide in the vertical direction when passing through the bracket 303. At the same time, after the bracket 301 is installed, the inner side of the limiting member 901 is in contact with the pile body 1, and the positioning blocks 902 are in contact with the positioning grooves 104 on the pile body 1. The positioning blocks 902 are embedded in the positioning grooves 104, so that the positioning blocks 902 can only move in a direction away from the pile body 1. However, at this time, the inner side of the limiting member 901 is in contact with the pile body 1, which restricts the positioning blocks 902 from moving in a direction away from the pile body 1, thereby achieving the positioning of the bracket 301.

[0052] In actual use, the user can first pull up the limiting member 901 and snap the positioning block 902 on the bracket 301 into the positioning groove 104, so that the positioning block 902 can only move in the direction away from the pile body 1. Then the user can release the limiting member 901, so that the inner side of the limiting member 901 is in contact with the pile body 1, and the top of the pile body 1 is in contact with the inner upper side of the limiting member 901, limiting the positioning block 902 on the bracket 301 from moving in the direction away from the positioning groove 104. This ensures the stability of the bracket 301 and facilitates user operation.

[0053] In this embodiment, the pile body 1 further includes a steel plate 101, a raised portion 102, a recessed portion 105, and two bent portions 103 to enhance the strength and stability of the pile body 1. The raised portion 102 is provided on the surface of the steel plate 101. The recessed portion 105 is provided on the surface of the steel plate 101 and is opposite to the raised portion 102.

[0054] In actual use, the raised portion 102 and the recessed portion 105 provide additional contact area and higher friction, thereby improving the pile body 1's ability to resist lateral displacement. This helps the pile body 1 maintain stability during construction and prevents displacement or deformation due to uneven force. The two bent portions 103 are used to splice multiple pile bodies 1 together by plugging them in from top to bottom.

[0055] The above specific embodiments do not limit the scope of protection of this utility model. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may be made based on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model shall be included within the scope of protection of this utility model.
