[0001] This utility model relates to the field of auxiliary equipment technology for building construction, and in particular to an upper and lower passage suitable for arc-shaped structures. Background Technology

[0002] During the construction of arch bridges and other curved structures, construction workers need to perform assembly and welding operations on the steel arch frame, so it is necessary to build special access passages to meet the passage requirements.

[0003] Traditional construction access routes are mostly temporary structures, which cannot be well adapted to the special shape of curved structures. This results in problems such as structural instability and non-standard construction, leading to higher safety risks for construction workers during passage and making it difficult to ensure the safety of high-altitude operations. Utility Model Content

[0004] The purpose of this utility model is to provide an upper and lower passage suitable for arc-shaped structures, aiming to solve the technical problems in the existing technology that cannot well adapt to the special shape of arc-shaped structures, resulting in structural instability and non-standard construction, leading to high safety risks for construction personnel during passage, and making it difficult to ensure the safety of high-altitude operations.

[0005] To achieve the above objectives, this utility model employs an upper and lower passage suitable for arc-shaped structures, including a cantilevered steel pipe passage frame. The cantilevered steel pipe passage frame is composed of multiple passage structure units, and an arched centerline pedestrian passage frame is fixedly connected to both ends of the cantilevered steel pipe passage frame. It also includes a stabilizing support unit, which is connected between two passage structure units. Scaffold boards are laid on the bottom inner side of the passage structure unit. The passage structure unit includes an upright and a connecting fastener installed at the end of the upright. A longitudinal horizontal bar is fixedly installed at the other end of the connecting fastener, and an adjusting fastener is fixedly installed on the outer side of the longitudinal horizontal bar. A transverse horizontal bar is fixedly installed at the other end of the adjusting fastener.

[0006] The cantilevered steel pipe passage has a width of 110cm, and the pedestrian passage at the center line of the arch frame has a width of 136cm.

[0007] The adjusting fastener includes a mounting block, a fixing block, a first bolt, a second bolt, a frame, and a mounting frame. The fixing block and the mounting frame are hinged to the left end of the frame. The first bolt is rotatably connected to the right end of the frame and is detachably connected to the fixing block.

The second bolt is rotatably connected to the left front end of the mounting frame and is detachably connected to the mounting block.

[0008] It also includes guardrails and thick wooden boards. The guardrails are fixedly installed on the outside of the cantilevered steel pipe channel frame; the thick wooden boards are laid on the top of the cantilevered steel pipe channel frame.

[0009] It also includes a safety net, which is fixedly connected to the bottom of the channel structure unit.

[0010] Compared with the prior art, this utility model has the following advantages: 1. By combining the cantilevered steel pipe passage frame with the arched centerline pedestrian passage frame, and adding stable support units, the overall structural stability is effectively improved. This allows the structure to better adapt to the special shape of the arc structure and avoids the safety hazards caused by the instability of traditional construction passages.

[0011] 2. The combination of guardrails, thick wooden planks, and safety nets provides comprehensive safety protection for construction workers.

Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Please see Figures 1-4 , Figure 1 This is a schematic diagram of the overall structure of an upper and lower channel suitable for an arc-shaped structure according to this utility model. Figure 2 This is a structural schematic diagram of the upright and connecting fastener of this utility model. Figure 3 This is a structural schematic diagram of the cantilevered steel pipe passageway frame and guardrail of this utility model. Figure 4 This is a structural diagram of the frame and mounting frame of this utility model. This utility model provides an upper and lower passage suitable for arc-shaped structures, including a cantilevered steel pipe passage frame 101, a passage structure unit, an arched centerline pedestrian passage frame 102, a protective unit 103, a guardrail 104, a thick wooden board 105, and a safety net 106. The passage structure unit includes uprights 107, connecting fasteners 108, longitudinal horizontal bars 109, adjusting fasteners, and transverse horizontal bars 110. The adjusting fastener includes mounting blocks 111, fixing blocks 112, a first bolt 113, a second bolt 114, a frame 115, and a mounting frame 116. The aforementioned solution solves the problem that traditional construction passages are mostly temporary structures, which cannot well adapt to the special shape of arc-shaped structures, resulting in structural instability and non-standard construction, leading to high safety risks for construction personnel during passage, and making it difficult to ensure the safety of high-altitude operations.

[0019] This specific embodiment includes a cantilevered steel pipe passageway 101, which is composed of multiple passageway structural units. An arched pedestrian passageway 102 is fixedly connected to both ends of the cantilevered steel pipe passageway 101. It also includes a stabilizing support unit connected between two passageway structural units, with scaffold boards laid on the bottom inner side of each passageway structural unit. Each passageway structural unit includes an upright 107 and a connecting fastener 108 installed at the end of the upright 107. A longitudinal horizontal bar 109 is fixedly installed at the other end of the 08. An adjusting fastener is fixedly installed on the outer side of the longitudinal horizontal bar 109. A transverse horizontal bar 110 is fixedly installed at the other end of the adjusting fastener. There are multiple uprights 107, multiple longitudinal horizontal bars 109, multiple transverse horizontal bars 110, multiple connecting fasteners 108, and multiple adjusting fasteners. The multiple uprights 107 are interconnected through the longitudinal horizontal bars 109 and the transverse horizontal bars 110 to form a stable frame structure. The connecting fastener 108 plays a crucial connecting role, ensuring a firm and reliable connection between the various members. The design of the adjusting fastener allows the position and angle of the horizontal bar 110 to be adjusted according to actual needs. Through the stable connection between the cantilevered steel pipe channel frame 101 and the pedestrian channel frame 102 at the center line of the arch frame, and the stable support unit between the channel structure units, a stable and adaptable upper and lower channel system is constructed. The upright 107 serves as the basic support of the channel structure unit, and the connecting fastener 108 installed at its end ensures a firm connection with the longitudinal horizontal bar 109. The adjusting fastener design on the outside of the longitudinal horizontal bar 109 allows the position and angle of the horizontal bar 110 to be adjusted, enabling the upper and lower channel to better conform to the contour of the arc structure, meet the needs of different construction scenarios, prevent structural instability and non-standard erection, reduce safety risks for construction personnel during passage, and thus ensure the safety of high-altitude operations.

[0020] The cantilevered steel pipe passage has a width of 110cm, and the pedestrian passage at the center line of the arch frame has a width of 136cm.

[0021] Secondly, the fixing block 112 and the mounting frame 116 are hinged to the left end of the frame 115; the first bolt 113 is rotatably connected to the right end of the frame 115 and is detachably connected to the fixing block 112; the mounting block 111 is rotatably connected to the left rear end of the mounting frame 116; the second bolt 114 is rotatably connected to the left front end of the mounting frame 116 and is detachably connected to the mounting block 111. The front ends of the frame 115 and the fixing block 112 are provided with arc-shaped grooves, and the left sides of the mounting frame 116 and the mounting block 111 are provided with arc-shaped grooves. The bottom left side is hinged to the top left side of the frame 115, and the bottom rear end of the mounting block 111 is hinged to the top front end of the mounting block 111. The frame 115 and the fixing block 112 are mounted on the longitudinal horizontal bar 109 by the first bolt 113, and the mounting block 111 and the mounting frame 116 are mounted on the transverse horizontal bar 110 by the second bolt 114. The transverse horizontal bar 110 drives the mounting frame 116 to rotate on the frame 115, thereby adjusting the position angle between the transverse horizontal bar 110 and the longitudinal horizontal bar 109.

[0022] Meanwhile, the guardrail 104 is fixedly installed on the outside of the cantilevered steel pipe passage frame 101; the thick wooden plank 105 is laid on the top of the cantilevered steel pipe passage frame 101. There are multiple guardrails 104, each composed of multiple steel pipes, which are connected and fixed by fasteners. The guardrail 104 is equipped with a protective net and horizontal safety rope nets are laid at 10m intervals. There are multiple thick wooden planks 105, and wooden beams and wooden plank crossbeams are provided between the thick wooden planks 105 and the cantilevered steel pipe passage frame 101 to support the top of the thick wooden planks 105. The guardrail 104 forms a solid protective barrier on the outside of the cantilevered steel pipe passage frame 101, effectively preventing construction workers from falling from the edge of the passage and ensuring their personal safety. The thick wooden planks 105 provide a stable and comfortable walking surface for construction workers and can also reduce vibration and noise during construction to a certain extent, thereby improving construction safety.

[0023] Then, the safety net 106 is fixedly connected to the bottom of the channel structure unit. There are multiple safety nets 106, which are interconnected by connecting ropes to form an integrated safety protection system. The safety net 106 is made of high-strength, wear-resistant material and has good toughness and impact resistance. It can effectively support tools, materials and other items that may fall during construction, preventing them from injuring construction workers below and further improving the safety of the construction process.

[0024] Using the vertical passageway suitable for arc-shaped structures in this embodiment, construction workers can safely and conveniently pass through during the construction of arc-shaped structures such as arch bridges. Before assembly, construction workers first reach the approximate work area via the pedestrian walkway frame 102 along the center line of the arch frame. The pedestrian walkway frame 102 is 136cm wide, ensuring that multiple people can pass side by side, improving passage efficiency. Then, construction workers walk on the cantilevered steel pipe walkway frame 101 according to the specific work position. The cantilevered steel pipe walkway frame 101 is 110cm wide and is composed of multiple passageway structural units. The scaffolding boards laid at the bottom of the inner side of the passageway structural unit provide a stable foothold for construction workers. The uprights 107 in the passageway structural unit serve as basic supports and are firmly connected to the longitudinal horizontal bars 109 through the connecting fasteners 108 at the ends. The multiple uprights 107 are interconnected through the longitudinal horizontal bars 109 and the transverse horizontal bars 110, forming a stable frame structure. The adjustment of the outer side of the longitudinal horizontal bars 109... The fasteners play a crucial role. Construction workers can adjust the position and angle of the horizontal bar 110 using the fasteners according to actual needs, allowing the upper and lower passages to better conform to the contours of the arc structure and meet the needs of different construction scenarios. During walking, the guardrail 104 fixedly installed on the outside of the cantilevered steel pipe passage frame 101 forms a sturdy protective barrier for construction workers. The guardrail 104 is equipped with a protective net and horizontal safety rope nets laid at 10m intervals, effectively preventing construction workers from falling from the edge of the passage. The thick wooden plank 105 laid on top of the cantilevered steel pipe passage frame 101 provides a stable and comfortable walking surface for construction workers. The thick wooden plank 105 and the cantilevered steel pipe passage frame 101 are supported by wooden beams and wooden plank crossbeams, which can also reduce vibration and noise during construction to a certain extent. When tools, materials, or other items are accidentally dropped, the safety net 106 fixedly connected to the bottom of the passage structure unit can effectively catch them, preventing them from injuring construction workers below, further improving the safety of the construction process.

[0025] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
