Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, specifically to a steel frame suitable for complex operating conditions of a station without affecting station operations. Background Technology

[0002] Against the backdrop of urban renewal, the challenge lies in the need for renovation and construction that does not affect the building's functionality, special functions, and safety requirements.

[0003] Some facilities used for facade construction (such as suspended scaffold structures) often require a sturdy and reliable support point for fixation during use. When the main building structure cannot find a suitable support point due to insufficient wall thickness or other reasons, such construction facilities cannot be used. In addition, during facade construction, the complex and narrow space makes it inconvenient to install construction equipment, and for facades with high traffic such as stations, it can affect pedestrian passage and even pose safety hazards. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a steel frame suitable for complex operating conditions of a station. This is achieved by combining multiple single steel frame units with connecting beams, laying platform plates on the connecting beams to form a construction platform, and creating a pedestrian walkway below the steel frame. Construction above does not affect pedestrian traffic below.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A steel frame suitable for complex operating conditions of a station without affecting its operation, the steel frame comprising at least two single steel frame units, the at least two single steel frame units being fixedly connected by a plurality of connecting beams, the plurality of connecting beams being divided into several layers in the height direction of the single steel frame units, platform plates being laid on the connecting beams located on the same layer, the platform plate located at the top layer protruding beyond the single steel frame unit in the width direction of the single steel frame unit, an outward cantilever beam being provided at the bottom of the platform plate located at the top layer, one end of the outward cantilever beam being fixedly connected to the single steel frame unit, the other end of the outward cantilever beam protruding beyond the single steel frame unit in the width direction of the single steel frame unit, and diagonal bracing being provided between the outward cantilever beam and the single steel frame unit.

[0007] The platform slab located at the top layer forms a top platform, and at least a portion of the outer periphery of the top platform is provided with protective railings.

[0008] Step ladders or straight ladders are installed between the platform slabs of adjacent layers.

[0016] Figure 3 This is a schematic diagram of the steel frame used in the construction of the station facade. Detailed Implementation

[0017] The features and other related features of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments, so as to facilitate the understanding of those skilled in the art:

[0018] like Figure 1-3 As shown in the figure, the markings represent: single steel frame unit 1, steel frame column 11, crossbeam 12, cantilever beam 13, diagonal brace 14, corbel 15, connecting beam 2, platform slab 3, guardrail 4, stair tread 5, roadbed box 6, station 7, and crane 8.

[0019] Example: Figure 1-3As shown, this embodiment relates to a steel frame suitable for complex operating conditions that do not affect station operations. It is suitable for use during the renovation of elevated station facades or other facade construction. The steel frame is erected outside the station, completely enclosing the renovation area. A pedestrian walkway is provided below, and a construction platform is provided above. Specifically, the steel frame includes at least two single steel frame units 1, spaced apart. Adjacent single steel frame units 1 are fixedly connected by several connecting beams 2. These connecting beams 2 are divided into several layers along the height direction of the single steel frame unit 1, meaning they connect at different heights. Platform plates 3 are laid on the connecting beams 2 at the same layer. For example, there are two connecting beams 2 at the same layer, arranged parallel to each other. Thus, construction platforms are constructed at different heights of the steel frame using platform plates 3 and connecting beams 2, facilitating construction work at different facade heights.

[0020] In this embodiment, the top platform slab 3 protrudes beyond the width of the single steel frame unit 1, meaning the width of the top platform slab 3 is greater than the width of the single steel frame unit 1, thus partially protruding beyond it. An outward-projecting beam 13 is provided at the bottom of the top platform slab 3. One end of the outward-projecting beam 13 is fixedly connected to the single steel frame unit 1, while the other end protrudes beyond it in the width direction, supporting the platform slab 3. Furthermore, a diagonal brace 14 is provided between the outward-projecting beam 13 and the single steel frame unit 1 to further strengthen the support for the top platform slab 3. Thus, a top platform is formed at the top of the steel frame, facilitating construction work on top of the steel frame.

[0021] Therefore, in this embodiment, multiple single steel frame units 1 are combined using connecting beams 2, and platform plates 3 are laid on the connecting beams 2 to form a construction platform. A pedestrian passage is formed below the steel frame, and the construction above does not affect the passage of pedestrians below.

[0022] In some embodiments, optionally, the platform slab 3 located at the top layer is formed as a top platform, and at least a portion of the outer periphery of the top platform is provided with guardrails 4. Specifically, guardrails 4 are provided on all sides of the top platform except the side closest to the facade to be constructed. By providing guardrails 4, construction workers can be prevented from falling from heights, ensuring construction safety.

[0023] Optionally, a staircase 5 or a straight ladder can be installed between the platform slabs 3 of adjacent floors. In this way, different floors can be connected vertically by the staircase 5 or the straight ladder, making it convenient for construction personnel to reach different construction heights.

[0024] In this embodiment, a fall protection safety net is wrapped around the bottom platform slab 3. Optionally, the fall protection safety net is a fine-mesh safety net, which can effectively prevent falling debris during construction, thereby ensuring pedestrian safety.

[0025] In some embodiments, the steel frame is erected and fixed on the roadbed box 6. Erecting the steel frame on the roadbed box 6 can effectively protect the road surface and prevent the steel frame from damaging the road surface.

[0026] In other embodiments, a corbel 15 is provided on the side of the single steel frame unit 1 closest to the construction surface, and a post-installed embedded part is provided on the construction surface. The single steel frame unit 1 is fixedly connected to the post-installed embedded part through the corbel 15. The corbel 15 on the single steel frame unit 1 is fixedly connected to the post-installed embedded part on the facade, thereby fixing the entire steel frame. At the same time, an external cantilever beam 13 is provided on the top of the steel frame to provide construction space and stacking space for high-altitude construction under special working conditions.

[0027] In this embodiment, the single steel frame unit 1 includes two steel frame columns 11 and several crossbeams 12 connecting the two steel frame columns 11. The several crossbeams 12 are connected at different height positions of the steel frame columns 11, providing a stable connection and lateral fixation effect.

[0028] like Figure 3 As shown, taking the renovation of the exterior facade of an elevated station as an example, the steel frame in this utility model is erected on both sides of the exterior of station 7, enclosing the entire renovation area. A pedestrian walkway is set below, and a construction platform is set above, so that construction above does not affect pedestrian passage below. Specifically, one of the above-mentioned steel frames is installed on each of the two exterior facades of station 7. For the exterior facade height, platform plates 3 are erected at different heights of the steel frame to form construction platforms, and the construction platforms at different heights can be connected vertically by stairs 5. The platform plates 3 erected on the top of the steel frame extend into the roof of station 7 to form a top platform. On the one hand, this is adapted to the station's structure, allowing construction workers to easily approach the roof of station 7 for construction. On the other hand, construction materials can be hoisted and stacked onto the top platform by a crane 8, avoiding accumulation at the bottom of the steel frame and affecting pedestrian passage.

[0029] In summary, the advantages of this utility model are: simple structure, easy assembly and disassembly, applicable to the construction of various building facades, by combining multiple single steel frame units with connecting beams, and laying platform plates on the connecting beams to form a construction platform, a pedestrian passage is formed under the steel frame, and the construction above does not affect the passage of pedestrians below.
