Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a split and reconfigurable foundation pit safety structure. Background Technology

[0002] In municipal and building construction projects, the excavation of foundation pits or trenches is a fundamental and frequent operation. To prevent pit wall collapse and ensure the safety of construction workers, foundation pits must be supported; at the same time, to prevent personnel, vehicles, or debris from accidentally falling into the foundation pit, safety barriers must be installed around the pit. Currently, foundation pit support and safety barriers are two completely independent systems that are constructed separately.

[0003] This traditional separate operation mode has significant drawbacks, including poor stability and high safety risks. Because the temporary fencing posts are typically only secured by base counterweights or simply driven into the ground, the foundation is not solid. This makes them highly susceptible to tipping over due to wind, equipment collisions, or human leaning, not only failing to provide protection but also potentially falling into the pit and causing secondary accidents. Utility Model Content

[0004] Therefore, it is necessary to provide a split and reconfigurable foundation pit safety structure to address the problem that temporary fence posts are usually fixed only by base counterweights or simply driven into the ground, which makes them prone to tipping over under wind, equipment collisions, or human leaning.

[0005] A split and reconfigurable foundation pit safety structure includes: a lower installation mechanism and an upper installation mechanism. The lower installation mechanism includes a lower support column and an installation column disposed on the upper surface of the lower support column. The upper installation mechanism includes an upper support column and a retaining plate. A connecting mechanism, comprising a connecting block, an elastic sleeve, and a compression assembly for compressing the elastic sleeve, wherein the connecting block is fixedly disposed on the lower surface of the upper support column, the elastic sleeve is disposed inside the connecting block, and the surfaces of the upper support column and the elastic sleeve are provided with mounting grooves corresponding to the mounting column. A support mechanism, comprising a support base and support legs.

[0006] In one embodiment, the extrusion assembly includes an extension column, a connecting rod, and an operating module. Two sets of extension columns are provided. A locking groove is provided on one side of the elastic sleeve. The two sets of extension columns are fixedly disposed on one side of the elastic sleeve and disposed on both sides of the locking groove. The connecting rod is slidably disposed inside the two sets of extension columns.

[0007] In one embodiment, the outer arc surface of the connecting rod is provided with two sets of limiting nuts, and the two sets of limiting nuts are located on both sides of a set of extension columns.

[0008] In one embodiment, the operation module includes a protrusion, a turntable, and an operating lever. The turntable is rotatably mounted on one end of a connecting rod, the protrusion is fixedly mounted on the outer arc surface of the turntable, and the operating lever is located on the side of the turntable away from the connecting rod.

[0009] In one embodiment, the bump and the turntable are located outside another set of extension posts, and the bump contacts the outside of the set of extension posts.

[0010] In one embodiment, the upper surface of the connecting block is provided with a connecting groove corresponding to the extrusion component, and the elastic sleeve is disposed inside the connecting groove via an installation plate.

[0011] In one embodiment, a set of mounting grooves on the upper surface of the connecting block are connected to the connecting groove, and a set of mounting posts are disposed inside the mounting groove on the inner side of the elastic sleeve.

[0012] In one embodiment, the support leg is threaded to the lower surface of the support base, and the upper surface of the support base is provided with several other sets of mounting posts.

[0013] Beneficial effects 1. The above-mentioned foundation pit safety structure is achieved by setting a connecting block on the lower surface of the upper support column and setting an installation column on the upper surface of the lower support column. Installation grooves are opened on both the connecting block and the elastic sleeve. The installation column on the upper surface of the lower support column is inserted into the installation groove on the connecting block and the elastic sleeve. Then, the installation column is clamped by the compression component. In this way, the upper support column is set on the upper surface of the lower support column, thereby ensuring the firmness of the installation of the upper support column and the enclosure plate and preventing the upper support column and the enclosure plate from tilting or falling into the foundation pit.

[0014] 2. The aforementioned foundation pit safety structure involves inserting the mounting column on the upper surface of the support base into the connecting block on the lower surface of the upper support column, and locking the mounting column on the upper surface of the support base with the elastic sleeve driven by the compression component. This allows the upper support column to be placed at the edge of the foundation pit through the support mechanism, thus transforming it into a standard temporary enclosure for continued use in this project or other projects. This avoids idle resources and improves the turnover rate of components and overall economic benefits. Attached Figure Description

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined with Figures 1-5 This invention describes a split, reconfigurable foundation pit safety structure.

[0020] In one embodiment, a split-reconfigurable foundation pit safety structure includes: a lower installation mechanism 100 and an upper installation mechanism 300. The lower installation mechanism 100 includes a lower support column 101 and an installation column 102 disposed on the upper surface of the lower support column 101. The upper installation mechanism 300 includes an upper support column 301 and a baffle plate 302. A support mechanism 400 includes a support base 401 and support legs 402. The support legs 402 are threadedly connected to the lower surface of the support base 401, and several other sets of installation columns 102 are disposed on the upper surface of the support base 401. In this embodiment, a support plate is installed between the two sets of lower support columns 101 to ensure the stability of the lower support columns 101 during support. A retaining wall 302 and a kick plate are installed between the two sets of upper support columns 301 to further improve edge protection. The upper support columns 301 are connected to the support base 401 via a connecting mechanism 200, so that after the lower support columns 101 and upper support columns 301 are separated, the support base 401 is connected to the upper support columns 301. The support leg 402 is configured as a telescopic rod structure, and the connection point with the support base 401 is configured as an adjustable hinge, allowing the support base 401 to adapt to uneven ground. By adjusting the length and angle of the telescopic rod, the support base 401 can stably stand on the edge of the backfilled but not yet completed foundation pit.

[0021] like Figure 1 , Figure 3 and Figure 5 As shown, the connecting mechanism 200 includes a connecting block 201, an elastic sleeve 203, and a pressing assembly for pressing the elastic sleeve 203. The connecting block 201 is fixedly disposed on the lower surface of the upper support column 301, and the elastic sleeve 203 is disposed inside the connecting block 201. The upper support column 301 and the elastic sleeve 203 have mounting grooves 202 corresponding to the mounting column 102 on their surfaces. The pressing assembly includes an extension column 205, a connecting rod 207, and an operating module. Two sets of extension columns 205 are provided. A locking groove is provided on one side of the elastic sleeve 203. The two sets of extension columns 205 are fixedly disposed on one side of the elastic sleeve 203 and are disposed on both sides of the locking groove. The connecting rod 207 is slidably disposed inside the two sets of extension columns 205. Two sets of limiting nuts are provided on the outer arc surface of the connecting rod 207, and the two sets of limiting nuts are located on both sides of one set of extension columns 205. In this embodiment, mounting posts 102 are provided on the upper surfaces of the lower support column 101 and the support base 401, and mounting grooves 202 corresponding to the mounting posts 102 are formed through the surfaces of the connecting block 201 and the elastic sleeve 203. By inserting the mounting posts 102 into the mounting grooves 202 on the surface of the connecting block 201, a set of mounting posts 102 are inserted into the mounting grooves 202 inside the elastic sleeve 203. Then, the operation module drives the two sets of extension posts 205 to move closer, thereby causing the elastic sleeve 203 to clamp the mounting posts 102 inside. The elastic sleeve 203 is provided with an anti-slip rubber layer, thereby ensuring the stability when the lower support column 101 or the support base 401 is connected to the upper support column 301. The positions of the connecting rod 207 and a set of extension posts 205 are relatively fixed by two sets of limit nuts. Then, the operation module drives the other set of extension posts 205 to move closer to the relatively fixed extension posts 205.

[0022] like Figure 3 , Figure 4 and Figure 5 As shown, the operating module includes a protrusion 208, a turntable 209, and an operating lever 210. The turntable 209 is rotatably mounted on one end of the connecting rod 207. The protrusion 208 is fixedly mounted on the outer arc surface of the turntable 209, and the operating lever 210 is located on the side of the turntable 209 away from the connecting rod 207. The protrusion 208 and the turntable 209 are located outside another set of extension posts 205, and the protrusion 208 contacts the outer side of the set of extension posts 205. The upper surface of the connecting block 201 is provided with a connecting groove 206 corresponding to the extrusion assembly. The elastic sleeve 203 is disposed inside the connecting groove 206 through the mounting plate 204. A set of mounting grooves 202 on the upper surface of the connecting block 201 is connected to the connecting groove 206, and a set of mounting posts 102 are disposed inside the mounting grooves 202 inside the elastic sleeve 203. In this embodiment, the elastic sleeve 203 is disposed inside the connecting groove 206 via the mounting plate 204, ensuring that the elastic sleeve 203 can be clamped slightly while maintaining the stability of the connection between the elastic sleeve 203 and the connecting block 201. An operating lever 210 is provided to facilitate the operator's rotation of the turntable 209. The turntable 209 synchronously rotates the protrusion 208, thereby pressing the extension column 205 through the protrusion 208. This causes the extension column 205 to move towards a relatively fixed set of extension columns 205. The approach of the two sets of extension columns 205 then causes the elastic sleeve 203 to clamp the internal mounting column 102. The protrusion 208 is designed as an arc-shaped block, ensuring that the elastic sleeve 203 can lock the mounting column 102 while preventing wear on the extension column 205 after prolonged use.

[0023] Working principle: By inserting the mounting post 102 on the upper surface of the lower support post 101 into the connecting block 201 below the upper support post 301, the upper support post 301 and the lower support post 101 are initially connected. Then, the operating lever 210 drives the turntable 209 to rotate. The turntable 209, through the pressing protrusion 208, drives the two sets of extension posts 205 to move closer together, thereby causing the elastic sleeve 203 to clamp the mounting post 102 inside, thus ensuring the connection between the lower support post 101 and the upper support post 301. Stability of the connection; when it is necessary to remove the lower support column 101, the operating lever 210 is rotated in the opposite direction to move the protrusion 208 away from the extension column 205. At this time, the upper support column 301 and the lower support column 101 can be quickly separated. Then, the mounting column 102 on the upper surface of the support base 401 is inserted into the connecting block 201. The upper support column 301 is then connected to the support base 401 through the connecting mechanism 200. Thus, the upper support column 301 is placed at the edge of the pit through the support mechanism 400.

[0024] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
