Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for municipal road and bridge construction, specifically to a modular quick-dismantling temporary construction passage. Background Technology

[0002] During the construction of municipal roads and bridges, temporary access roads are necessary to ensure the passage of construction workers and the transport of small equipment. Currently, there are two main types of commonly used temporary access roads: one is the traditional wooden access road, constructed from planks and steel pipes, which suffers from weak load-bearing capacity, cumbersome assembly and disassembly, and high material consumption, especially susceptible to moisture damage in damp foundation pit environments; the other is the existing modular steel access road, which solves the problem of reuse, but generally suffers from a fixed structure, lack of folding functionality, large space requirements when stored, and non-adjustable leg height, making it difficult to adapt to uneven construction sites. Furthermore, the lateral expansion width of existing modular access roads is limited, mostly only allowing passage for a single person, and cannot accommodate the passage needs of small equipment (such as handcarts and small generators). These shortcomings result in insufficient adaptability to construction scenarios, transportation convenience, and utilization efficiency of existing temporary access roads. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a modular quick-disassembly temporary construction passage that can achieve the functional goals of "quick splicing, height adjustment, folding storage, and multi-scenario adaptation" in the existing temporary passage, which has insufficient load-bearing capacity, inconvenient disassembly and storage, poor terrain adaptability and limited expansion capability.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a modular quick-release temporary passage, including several modular units and foldable guardrails. The modular unit includes a rectangular steel frame, the top surface of which is fixedly covered with an anti-slip panel. Adjustable support legs are vertically welded to the four corners of the bottom of the rectangular steel frame. Connecting components are horizontally welded to the bottom of the four sides of the rectangular steel frame. When the modular unit is used as a side plate, a U-shaped bracket is welded to the side frame of the rectangular steel frame, and the foldable guardrail is fixedly installed in the U-shaped bracket.

[0005] Furthermore, the rectangular steel frame is welded from structural steel, and an anti-slip panel is fixed to the top surface of the rectangular steel frame with countersunk bolts. The anti-slip panel is made of patterned steel plate, and the diamond pattern on the surface of the patterned steel plate can improve the anti-slip performance and prevent construction workers from slipping.

[0006] Furthermore, the adjustable support leg consists of a fixed sleeve and a movable support rod. The top of the fixed sleeve is fully welded to the rectangular steel frame, and the movable support rod is inserted into the fixed sleeve and positioned by the locking bolts on the side wall of the fixed sleeve, adapting to different slopes or undulating construction grounds.

[0007] Furthermore, an anti-slip pad is welded to the bottom end of the movable support rod. The anti-slip pad is made of steel plate with serrated anti-slip texture processed on the bottom surface to increase friction with the ground and prevent the passage from slipping.

[0008] Furthermore, the connecting component adopts a "ear plate + plug rod" connection structure. Each modular unit has two sets of ear plates and plug rods arranged opposite each other on the side frame of the rectangular steel frame. The ear plates are horizontally welded to the lower part of the rectangular steel frame, and the plug rods are vertically welded to the lower part of the rectangular steel frame.

[0009] Furthermore, the ear plate is provided with a circular through hole, which is adapted to the diameter of the insertion rod.

[0010] Furthermore, the foldable guardrail includes an upper horizontal bar, a lower horizontal bar, and a vertical bar. The two ends of the vertical bar are connected to the upper and lower horizontal bars via hinged folding hinges, allowing the foldable guardrail to fold along the axis of the vertical bar. The lower ends of the lower horizontal bar are welded with cylindrical clips, which can be inserted into U-shaped brackets on the side of the rectangular steel frame for quick installation and disassembly.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. Convenient storage and small space occupation: With the foldable guardrail design, the volume of a single unit is reduced by 60% when stored compared to the unfolded state, solving the problem of inconvenient transportation of traditional modular channels.

[0012] 2. High adaptability and wide scene coverage: The adjustable outriggers are adaptable to terrain with a height range of 30-80cm. They can be assembled and expanded horizontally and vertically as needed. They can meet the narrow passage requirements of foundation pit operations and also carry small equipment (such as welding machines) to pass through the bridge beam installation site.

[0013] 3. Highly efficient installation and high reusability: Modular units and foldable guardrails are connected by plug-in method, which makes assembly fast; the whole structure is made of steel and has a long service life.

[0014] 4. Stable structure and high safety: The connecting components and anti-slip adjustable support legs ensure the stability of the passageway, and the foldable guardrails can effectively prevent people from falling, which complies with municipal construction safety regulations.
