Technical Field

[0001] This invention relates to the technical field of formwork support systems for cast-in-place structures in building construction, and in particular to a cantilevered outdoor corridor support unloading device and construction method. Background Technology

[0002] With the development of urban construction in China, in order to meet fire protection requirements, outdoor space is being developed and utilized without occupying indoor building area to ensure fire protection requirements are met.

[0003] Most fire-fighting corridors are designed with reinforced concrete structures, characterized by their large size, large span, high ground clearance, and lack of proximity to the main structure. These corridors require formwork and pouring to ensure their usability, appearance, and quality. To guarantee the quality of structural construction, the formwork support system must be highly safe. During construction, the traditional method of unloading the upper steel wire ropes of the cantilevered I-beams has revealed many challenges. Summary of the Invention

[0005] In a first aspect, the present invention provides a cantilevered outdoor corridor support unloading device, including a cantilever beam assembly, an anchoring assembly, and an unloading and support assembly. The cantilever beam assembly is provided with a connecting ear plate at its end. The anchoring assembly includes pre-embedded anchors and adjustable anchors. The unloading and support assembly includes a tie rod and a brace.

[0006] Preferably, one end of the diagonal brace is connected to the bottom of the cantilever beam assembly, and the other end is connected to the main building structure or ground foundation through an adjusting sleeve.

[0007] Preferably, guardrails and anti-slip mats are also included.

[0008] Preferably, the cantilever beam assembly is made of Q235 ordinary carbon structural steel, and the main cantilever beam is made of 16# I-beam.

Embed the pre-embedded anchors into the main structure of the building and connect the cantilever beam components through adjustable anchors. S2. Adjust the length of the diagonal brace using the adjusting sleeve of the unloading and support components to ensure that the cantilever beam assembly is in a horizontal and stable state. S3. After installing the protective components, the cantilever operation can proceed. S4. When disassembling, reverse the operation of each connecting part for easy reuse.

[0011] In summary, the present invention has at least one of the following beneficial technical effects: Structural stability: Through the cooperation of main and auxiliary cantilever beams, as well as the synergistic effect of anchoring and support adjustment components, a stable stress system is constructed, which effectively disperses the load, reduces the risk of structural deformation, improves construction safety, is not easily deformed, is resistant to high temperatures, and is not easily affected by humid weather and corrosion; Reasonable stress distribution: The I-shaped cross-section cantilever beam and adjustable anchorage and support structure make the load transfer path clear, conform to the mechanical principles, reduce stress concentration, and extend the service life of the device. Easy to install and disassemble: The components are connected in a detachable and adjustable manner, which makes construction and operation simple, saves labor and time costs, facilitates the reuse of equipment, extends the service life of materials, and effectively reduces long-term operating costs; Highly adaptable: The anchoring position and diagonal brace length can be adjusted according to different building structures, cantilever length and height requirements, making it suitable for various building construction scenarios.

[0015] The following combination Figures 1-2 The present invention will be described in further detail below.

[0016] This invention discloses a cantilevered outdoor corridor support unloading device and construction method. The device includes a cantilever beam assembly 1, an anchoring assembly 2, and an unloading and support assembly 3.

[0017] Cantilever beam assembly 1: Made of Q235 ordinary carbon structural steel, the main cantilever beam is made of 16# I-beam, the lower diagonal brace and diagonal tie rod are connected at a certain angle (as shown in the figure, the angle relationship can be precisely defined according to the actual marking), the main triangular frame is divided into multiple triangular structures to increase stability and form a stable force-bearing structure. The end of the main cantilever beam is equipped with connecting ear plates to ensure welding quality and surface anti-corrosion treatment.

[0018] Anchoring component 2: includes pre-embedded anchors and adjustable anchors. The pre-embedded anchors are pre-embedded in the main building structure. One end of the adjustable anchor is adapted to the pre-embedded anchor, and the other end is detachably connected to the connecting ear plate of the cantilever beam component 1 through bolts. The anchoring position and angle can be adjusted according to construction needs. It is equipped with matching bolts and nuts and is rust-proofed.

[0019] Unloading and support component 3: It consists of a lower diagonal brace and a diagonal tie rod. One end of the diagonal brace is connected to the bottom of the cantilever beam component 1, and the other end is connected to the main building structure or ground foundation through an adjusting sleeve. The adjusting sleeve can be rotated to adjust the length of the diagonal brace to adapt to different cantilever height and angle requirements and ensure the force balance of the cantilever device.

[0020] We can also process guardrails (materials such as steel pipes) and anti-slip mats (using rubber or metal plates with good anti-slip properties and pressing anti-slip textures), and standardize the guardrail connectors.

[0021] The construction method of the cantilevered outdoor corridor support unloading device according to an embodiment of the present invention includes the following steps: S1. Embed the pre-embedded anchors into the main structure of the building and connect the cantilever beam assembly 1 through adjustable anchors. S2. Adjust the length of the diagonal brace using the adjusting sleeve of the support adjustment component to make the cantilever beam assembly 1 horizontal and stable. S3. After the protective components are installed, cantilever operations can be carried out, such as scaffolding erection and material stacking. S4. When disassembling, reverse the operation of each connecting part for easy reuse.

[0022] This invention has the following advantages: 1. Structural stability: Through the cooperation of main and auxiliary cantilever beams, as well as the synergistic effect of anchoring and support adjustment components, a stable stress system is constructed, which effectively disperses the load, reduces the risk of structural deformation, improves construction safety, and is not easily deformed, resistant to high temperatures, and not easily affected by humid weather and corrosion.

[0023] 2. Reasonable stress distribution: The I-shaped cross-section cantilever beam and adjustable anchoring and support structure make the load transfer path clear, conform to the mechanical principles, reduce stress concentration, and extend the service life of the device.

[0024] 3. Easy to install and disassemble: The components are connected in a detachable and adjustable manner, which makes construction and operation simple, saves labor and time costs, facilitates the reuse of equipment, extends the service life of materials, and effectively reduces long-term operating costs.
