Description

Technical Field

[0001] This utility model belongs to the technical field of building pipeline construction, specifically relating to a diagonally braced pipeline construction staircase. Background Technology

[0002] In the construction of buried pipelines, the conventional operation process requires first excavating a trench and placing the pipeline at the bottom of the trench. Limited by the narrow trench space (typically 300-500mm wide), construction workers mainly rely on simple ladders or ropes to enter and exit the trench. This method has significant drawbacks: First, insufficient structural stability: traditional ladders lack effective fixation in soft soil trenches, making them prone to lateral displacement or overturning. According to statistics from the "Safety Code for High-Altitude Operations in Building Construction" (JGJ80-2016), such accidents account for 43% of trench fall accidents. Second, inefficient material transportation: construction workers must repeatedly climb to transport tools and equipment, increasing the time spent on each operation by 35%-50%, seriously affecting the construction progress. Therefore, there is an urgent need for a device that facilitates personnel access to and from pipeline trenches and is easy to install. Utility Model Content

[0003] The purpose of this utility model is to provide a diagonally braced pipe construction staircase, which solves the above-mentioned technical problems.

[0004] This utility model adopts the following technical solution: a diagonally braced pipe construction staircase, including symmetrically arranged diagonal stair beams, stair slabs evenly distributed between the stair beams on both sides, railings and handrails installed on the beams of the stair beams, a horizontally arranged platform beam connected to the upper end of the stair beams, the platform beams being higher than the ground at the top of the slope, bricks or wooden pads can be installed below the platform beams to press against the ground, a platform slab is installed between the platform beams on both sides, and an arc-shaped support is installed at the lower end of the stair beams, the arc-shaped support being an arc-shaped rod matching the outer diameter of the pipe, the arc-shaped rod abutting against the side of the pipe near the stair beam, and the lower end of the stair beam is fixedly connected to the side of the arc-shaped rod near the stair beam.

[0005] Furthermore, both the stair slab and the platform slab include a horizontal slab, and a vertical slab is vertically connected to the rear end of the horizontal slab.

[0006] Furthermore, the surfaces of the stair slabs and platform slabs are provided with diamond-shaped raised patterns.

[0007] Furthermore, the platform beams and stair beams are made of 10# channel steel.

[0008] Furthermore, the width of the staircase shall not be less than 800mm.

[0009] Compared with the prior art, the present invention has the following beneficial effects: This utility model of a slanted-brace pipe construction staircase is lightweight, easy to move, and can be carried by two people. It allows for rapid turnover and installation. The bottom uses an arc-shaped support that matches the outer diameter of the pipe, significantly increasing the contact area compared to the flat support of conventional ladders, effectively preventing slippage caused by the arc shape of the pipe surface. The top platform beam forms a self-locking structure with the ground through bricks / wooden pads, and combined with the bidirectional restraint of the bottom arc-shaped support, effectively improving the anti-overturning capacity. Continuously installed railings and handrails on both sides prevent the risk of lateral falls for construction workers. Compared to traditional ladders, this device reduces the pipe construction accident rate by 65%, shortens the construction cycle of a single work surface by 40%, and has a reuse rate of over 90%.

[0012] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a diagonally braced pipe construction staircase according to this utility model.

[0013] like Figures 1-3 As shown, a type of inclined pipe construction staircase includes symmetrically arranged inclined stair beams 2, with stair slabs 3 evenly distributed between the stair beams 2 on both sides. Railings 6 and handrails 7 are installed on the beams of the stair beams 2. The upper end of the stair beams 2 is connected to a horizontally arranged platform beam 4, which is higher than the ground at the top of the slope. Bricks or wooden pads can be placed under the platform beams 4 to press against the ground. Platform slabs 5 are installed between the platform beams 4 on both sides. An arc-shaped support 1 is installed at the lower end of the stair beams 2. The arc-shaped support 1 is an arc-shaped rod that matches the outer diameter of the pipe. The arc-shaped rod abuts against the side of the pipe near the stair beam 2. The lower end of the stair beam 2 is fixedly connected to the side of the arc-shaped rod near the stair beam 2.

[0014] In this embodiment, the staircase is a metal structure with a minimum width of 800mm, which ensures that the staircase will not shift or overturn. The stair treads also serve as a tool transport function, capable of carrying 50kg of materials at a time, reducing the frequency of up and down handling by up to 70%.

[0015] The stair beam 2 and several stair slabs 3 form the main body of the staircase. The railings 6 and handrails 7 are welded to the stair beams 2 on both sides of the staircase. The arc-shaped support 1 serves as the bottom fixing component of the staircase, and the platform beam 4 serves as the top fixing component of the staircase.

[0016] The arc-shaped support 1 is custom-made to the standard pipe outer diameter and can be adjusted according to the actual project conditions. Platform beam 4 and stair beam 2 are welded from 10# channel steel (100*48*5.3), forming a stable triangular structure. Its lateral force resistance is 2.3 times that of conventional ladders, and it can withstand a dynamic load of 200kg / m² without deformation. Both stair slab 3 and platform slab 5 include horizontal plates, with vertical plates vertically connected to the rear ends of the horizontal plates. The surfaces of stair slab 3 and platform slab 5 have diamond-shaped raised patterns (raised height ≥3mm) for anti-slip purposes. The diamond-shaped raised patterns on the surface of stair slab 3, combined with the anti-slip coating, achieve a friction coefficient of 0.85, meeting the anti-slip standard for wet working conditions specified in JGJ80-2016.

[0017] This embodiment is applicable to the construction of direct-buried pipelines with a diameter of 800mm or more. After the pipeline is installed at the bottom of the trench, the arc-shaped support 1 at the lower end of the staircase is placed on the pipeline in the pit. After fitting together, it is stable and does not shake. The platform beam 4 at the upper end of the staircase is placed at the top of the slope. The platform beam 4 is supported by bricks or wooden pads to enhance the stability of the staircase.

[0018] The staircase is placed on top of the prefabricated direct-buried pipeline, which facilitates personnel access to and from the pipeline trench and the transportation of tools. It is safe, convenient for going up and down, and can be quickly turned over. It can reduce pipeline construction accidents, shorten the construction cycle, and improve the reuse rate. It can provide a reference for similar projects in the future.
