Description

Technical Field

[0001] This utility model is applied to the field of foundation pit construction, specifically relating to a foundation pit edge protection structure. Background Technology

[0002] Pit edge guardrails are used during pit construction to warn personnel in the construction area of ​​potential dangers, prevent construction workers or passersby from accidentally falling into the pit, reduce the risk of fall injuries and fatalities, and provide a solid barrier for personnel safety. Additionally, they have a primary function of preventing debris from sliding down the edge of the pit and injuring workers inside.

[0003] When constructing existing perimeter protection structures for foundation pits, it is necessary to bind and fix the reinforcing beams, horizontal pipes, short longitudinal pipes, and long longitudinal pipes at the nodes of the beams using wire before laying dense safety netting. Using this installation method, relying solely on the binding wires to connect the components (reinforcing beams, longitudinal pipes, and horizontal pipes) makes the wires prone to loosening and breakage, compromising the overall stability of the protective frame. Furthermore, the wire binding process requires cutting the wire, wrapping it around the rods, and twisting it for fixation. These actions must be repeated at each connection point, especially when there are many guardrail components and dense connection nodes. A significant amount of time is spent on binding each point individually. Additionally, inexperienced operators often make repeated adjustments, extending construction time and increasing human error. Moreover, different workers use different binding techniques and apply varying degrees of force, making it difficult to maintain consistent guardrail quality. If the position or angle of the guardrail needs adjustment after binding, untying and rebinding the wires adds further time. Utility Model Content

[0004] This application aims to address the problem that when steel pipe nodes are bound with wire during the construction of foundation pit edge protection structures, the nodes are prone to loosening and breakage, making it difficult to guarantee the overall stability of the protection frame. Therefore, this application provides a foundation pit edge protection structure.

[0005] The technical solution of this application is:

[0006] A foundation pit edge protection structure, comprising a longitudinal pipe support structure, a short longitudinal pipe, a long longitudinal pipe, and a reinforcing beam;

[0007] The longitudinal tube support structure is longitudinally inserted and connected to the short longitudinal tube and the long longitudinal tube respectively. The reinforcing beam is rotatably connected to the side of the long longitudinal tube near the top through an ear plate. The other end of the reinforcing beam is rotatably connected to the insert cylinder. The insert cylinder is inserted into the short longitudinal tube from top to bottom. The longitudinal tube support structure, the long longitudinal tube and the reinforcing beam form a triangular support frame structure.

[0008] The longitudinal tube support structure supports the bottom of the insert, and a foot tube is connected below the plane of the longitudinal tube support structure, and the foot tube is used to support the plane of the longitudinal tube support structure.

[0009] Furthermore, the plane of the longitudinal tube support structure is provided with short tube insertion holes for inserting short longitudinal tubes and long tube insertion holes for inserting long longitudinal tubes, and the diameters of the short tube insertion holes and the long tube insertion holes are the same.

[0010] Furthermore, positioning sleeves are connected to the bottom of the short tube insertion hole and the long tube insertion hole respectively, and a short longitudinal tube and a long longitudinal tube are inserted into the two positioning sleeves respectively.

[0011] Furthermore, a locking hole is transversely opened on the surface of the short longitudinal tube, and a bolt assembly is inserted into the locking hole, with the bolt assembly resting against the top of the insert.

[0012] Furthermore, the short longitudinal tube and the long longitudinal tube are steel pipe structures, and the short longitudinal tube and the long longitudinal tube are arranged in parallel.

[0013] Furthermore, a dense safety net is connected to the long longitudinal tube.

[0014] Furthermore, a toe wall is provided below the longitudinal tube support structure.

[0015] Compared with the prior art, this application has the following advantages:

[0016] During installation, the longitudinal tube support structure is placed in the installation area, and the foot tubes below the longitudinal tube support structure support it. The reinforcing beam on the long longitudinal tube is rotated so that the insert at the end of the reinforcing beam is aligned with the short longitudinal tube. The insert is then inserted into the short longitudinal tube. The long longitudinal tubes are then passed through the long tube insertion holes on the longitudinal tube support structure in sequence, and the bottom of the long longitudinal tubes is inserted into the ground. Following the above operations, the protective frame is installed sequentially at the edge of the pit. Finally, a dense safety net is placed between two adjacent long longitudinal tubes to complete the installation of the frame.

[0017] This invention eliminates the need for tools during installation. By interlacing and rotating short longitudinal tubes, long longitudinal tubes, reinforcing beams, and longitudinal tube support structures, the components can be quickly installed. Compared to the cumbersome operation of binding with wire, this significantly reduces the installation time of the protective frame.

[0018] This invention replaces the traditional method of binding with iron wire, which is prone to loosening and breakage, significantly improving structural stability and protective reliability. Furthermore, this structural component has a standardized installation process, ensuring good consistency in protective installation across different locations; whereas wire binding relies on worker experience, making it difficult to maintain consistent installation quality. This structure facilitates batch, standardized construction. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0027] Specific implementation method one: Combining Figure 1 — Figure 6 This embodiment describes a foundation pit edge protection structure, which includes a longitudinal pipe support structure 1, a short longitudinal pipe 2, a long longitudinal pipe 3, and a reinforcing beam 4.

[0028] The longitudinal tube support structure is longitudinally inserted and connected to the short longitudinal tube and the long longitudinal tube respectively. The reinforcing beam is rotatably connected to the side of the long longitudinal tube near the top through the ear plate 5. The other end of the reinforcing beam is rotatably connected to the insert 6. The insert is inserted into the short longitudinal tube from top to bottom. The longitudinal tube support structure, the long longitudinal tube and the reinforcing beam form a triangular support frame structure.

[0029] The longitudinal tube support structure supports the bottom of the insert, and a foot tube 7 is connected to the lower part of the plane of the longitudinal tube support structure, and the foot tube is used to support the plane of the longitudinal tube support structure.

[0030] The foot tube 7 is a round tube with the same diameter as the short longitudinal tube 2 and the long longitudinal tube 3. The top end of the foot tube 7 is vertically connected to the bottom surface of the longitudinal tube support structure 1 by welding. The foot tube 7 can support the longitudinal tube support structure 1 and keep the longitudinal tube support structure 1 at a suitable height.

[0031] Specific Implementation Method Two: Combining Figure 1 — Figure 6 This embodiment describes a foundation pit edge protection structure. The longitudinal pipe support structure has short pipe insertion holes 8 for inserting short longitudinal pipes and long pipe insertion holes 9 for inserting long longitudinal pipes on its plane, and the short pipe insertion holes and long pipe insertion holes have the same diameter.

[0032] The longitudinal tube support structure is a rectangular steel plate structure, and the short tube insertion hole 8 and the long tube insertion hole 9 are symmetrically arranged. The diameter of the short tube insertion hole and the long tube insertion hole is slightly larger than the outer diameter of the short longitudinal tube 2 and the long longitudinal tube 3, so that the short longitudinal tube 2 and the long longitudinal tube 3 pass through the longitudinal tube support structure 1 respectively, making the short longitudinal tube 2 and the long longitudinal tube 3 perpendicular to the longitudinal tube support structure 1.

[0033] Specific implementation method three: Combining Figure 1 — Figure 6 This embodiment describes a foundation pit edge protection structure, wherein positioning sleeves 10 are respectively connected below the short pipe insertion hole and the long pipe insertion hole, and a short longitudinal pipe and a long longitudinal pipe are respectively inserted into the two positioning sleeves.

[0034] The positioning sleeve 10 is a metal sleeve structure, and the top end of the positioning sleeve 10 is fixed below the insertion hole of the longitudinal tube support structure 1 by welding. The center of the positioning sleeve 10 is on the same vertical line as the center of the short tube insertion hole 8 and the long tube insertion hole 9 of the long longitudinal tube. By setting the positioning sleeve 10 below the longitudinal tube support structure 1, the area of ​​the short longitudinal tube 2 and the long longitudinal tube 3 can be increased, thereby improving the stability of the short longitudinal tube 2 and the long longitudinal tube 3 on the longitudinal tube support structure 1.

[0035] Specific implementation method four: Combination Figure 1 — Figure 6 This embodiment describes a foundation pit edge protection structure, wherein a locking hole is laterally opened on the surface of the short longitudinal tube, and a bolt assembly 11 is inserted into the locking hole, with the bolt assembly resting against the top of the insert.

[0036] After the short longitudinal tube passes through the insertion hole of the longitudinal tube support structure 1, the insertion sleeve 6 fitted on the short longitudinal tube 2 is positioned above the longitudinal tube support structure 1. When the bolt assembly 11 is inserted into the locking hole of the short longitudinal tube 2, it limits the insertion sleeve 6 and prevents the insertion sleeve 6 from falling off the short longitudinal tube 2.

[0037] Specific Implementation Method Five: Combining Figure 1 — Figure 6 This embodiment describes a foundation pit edge protection structure, wherein the short longitudinal pipe and the long longitudinal pipe are steel pipe structures, and the short longitudinal pipe and the long longitudinal pipe are arranged in parallel.

[0038] The short longitudinal pipe 2 and the long longitudinal pipe 3 have different lengths. The bottom of the short longitudinal pipe 2 and the long longitudinal pipe 3 are inserted into the ground to a depth of 0.5m, so that the short longitudinal pipe 2 and the long longitudinal pipe 3 are parallel to each other, thereby completing the installation of the main structure of the pit edge protection structure. The distance between the short longitudinal pipe 2 and the long longitudinal pipe 3 is the same as the distance between the two short pipe insertion holes 8 and the long pipe insertion holes 9 on the longitudinal pipe support structure 1.

[0039] Specific Implementation Method Six: Combination Figure 1 — Figure 6 This embodiment describes a foundation pit edge protection structure, in which a dense safety net 12 is connected to the long longitudinal pipe. A toe wall 13 is provided below the longitudinal pipe support structure.

[0040] Specific implementation method seven: Combination Figure 1 — Figure 6 This embodiment describes a foundation pit edge protection structure. During installation, a longitudinal pipe support structure 1 is placed in the installation area. The foot pipes 7 below the longitudinal pipe support structure 1 support it, ensuring the height of the longitudinal pipe support structure 1 from the ground is equal to the length of the foot pipe 7, thus maintaining a distance between the longitudinal pipe support structure 1 and the ground. A short longitudinal pipe 2 is inserted through a short pipe insertion hole 8 on the longitudinal pipe support structure 1, with the short longitudinal pipe 2 inserted to a depth of approximately 0.5m into the ground. A long longitudinal pipe 3 is then passed through a long pipe insertion hole 9 on the longitudinal pipe support structure 1. During this process, a reinforcing beam 4 on the long longitudinal pipe 3 can rotate on the long longitudinal pipe 3 via a pin. The other end of the reinforcing beam 4... The insert 6 on the long longitudinal pipe 3 rotates via a pin. During the mixing process, the pin rotates the reinforcing beam 4 and the insert 6 on the reinforcing beam 4, making the insert 6 and the short longitudinal pipe 2 in the same vertical line. When the long longitudinal pipe 3 is inserted vertically downward into the long pipe insertion hole 9, the insert 6 on the reinforcing beam 4 is inserted into the short longitudinal pipe 2, making the long longitudinal pipe 3 inserted to a depth of 0.5m into the ground. The bolt assembly 11 is inserted into the locking hole in the short longitudinal pipe 2 to prevent the insert 6 from falling off the short longitudinal pipe 2. Following the same operation, the protective frame is installed sequentially at the edge of the pit. Finally, the dense safety net is placed between two adjacent long longitudinal pipes 3. The installation of the short longitudinal pipe 2, long longitudinal pipe 3 and reinforcing beam 4 can be completed quickly without the aid of tools, improving the installation efficiency.

Although this application has disclosed the preferred embodiment as above, it is not intended to limit this application. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of this application.
