Description

Technical Field

[0001] This invention belongs to the technical field of air conditioning scaffolding systems, specifically relating to an air conditioning scaffolding system and construction method suitable for MiC buildings. Background Technology

[0002] Air conditioner outdoor units are typically installed on air conditioner brackets. Traditionally, air conditioner brackets require drilling holes in the wall and securing them with expansion bolts or other fasteners. This method can easily damage the building structure. Currently, with the promotion of MiC (Multi-Instrument Construction) technology, MiC walls are increasingly being used. However, existing air conditioner brackets are not suitable for MiC walls. Firstly, lightweight MiC walls lack sufficient load-bearing capacity, making the brackets prone to falling. Secondly, integrated MiC walls require pre-drilled holes for wiring; installing the air conditioner bracket later requires drilling holes in the wall, which can damage these pre-drilled holes, making wiring difficult. Furthermore, drilling holes in the wall can compromise the overall aesthetics of the MiC wall. Currently, there is a need to develop an air conditioning scaffolding system suitable for MiC buildings to improve the reliability of the connection between the air conditioning scaffolding and the MiC building unit; there is also a need to invent a construction method for the air conditioning scaffolding system to guide people to first fabricate the pre-embedded components together with the MiC building unit, and then complete the fixing of the air conditioning scaffolding, so as to improve the reliability of the connection between the air conditioning scaffolding and the MiC building unit.

[0048] In one embodiment, the present invention provides an air conditioning frame system suitable for MiC buildings, which has the following advantages: (1) Deep integration of pre-embedded components with MiC building units (core advantage): ① Integrated design of MiC building units and pre-embedded components: The pre-embedded components are integrated into the structure of the MiC building unit, and are an integral part of the MiC building unit, rather than a later-installed accessory. This fundamentally avoids the problem that traditional post-installed air conditioning brackets can easily damage the integrity of the wall structure.

[0049] ② Ensuring structural continuity and safety: This invention uses adjustable steel reinforcement components to allow longitudinal steel reinforcement to overlap with the main steel reinforcement of MiC building units, ensuring the continuity of the steel reinforcement network and avoiding the problem of reduced local load-bearing capacity of the wall due to structural interference cutting the steel reinforcement, thereby improving the structural safety of MiC buildings.

[0050] (2) Components can be prefabricated in the factory (advantages in manufacturing and installation): ① Factory production: Pre-embedded components are precisely positioned, installed, and cast into MiC building units in the factory. The factory's operating environment is controllable, with complete processing equipment, and the processing quality of the components is stable and reliable, avoiding on-site construction errors and uncertainties (here, "on-site" refers to the final installation location of the MiC building unit, not the factory). ②Simplified on-site installation: The air conditioner bracket is connected to the reserved opening on the outer end plate by the first bolt (i.e., high-strength bolt). The installation process is simple and quick, without the need to drill holes in the wall on site. This greatly shortens the installation time of the air conditioner bracket, reduces the installation difficulty of the air conditioner bracket, and significantly improves the on-site installation efficiency, which is in line with the core concept of rapid hoisting and assembly of MiC building units.

[0051] ③ Eliminate complex high-altitude operations: For example, the integration of pre-embedded components and MiC building units has been successfully completed on the factory ground, so there is no need to drill installation holes in the wall at high altitudes later; on site, it is only necessary to connect the air conditioner bracket to the outer end plate with the first bolt and fix the air conditioner outdoor unit to the support frame of the air conditioner bracket, which greatly reduces the difficulty and risk of high-altitude operations.

[0052] (3) Structural safety and stability (advantages in load-bearing performance): ① Reliable anchorage of pre-embedded components: For example, the pre-embedded columns are connected to the crossbeams of the MiC box, and the pre-embedded columns and connectors are embedded in the concrete, and there are longitudinal steel bars connected to the main steel bars of the MiC building unit. The anchorage is very reliable. The load-bearing capacity and pull-out resistance of the pre-embedded components are far superior to the expansion bolts that rely on bonding force or small-scale expansion in the later stage. They are particularly suitable for use in lightweight MiC walls, solving the problem of insufficient load-bearing capacity of MiC walls when installing air conditioner brackets in the later stage.

[0053] ② Overall stress optimization: The load is effectively transferred to the overall structure of the MiC wall through the outer end plate, connectors and embedded columns, which disperses the stress and effectively avoids structural damage caused by excessive local stress; among them, the first bolt (i.e. high-strength bolt) is more shear resistant (effectively avoiding shear failure of the bolt itself), ensuring the reliability of the connection between the air conditioner bracket and the outer end plate.

[0054] ③ Improve the wind and earthquake resistance of the air conditioner bracket: The overall design makes the air conditioner bracket system of the present invention (such as the pre-embedded components) part of the MiC building unit, and its wind and earthquake resistance is better than that of the traditional air conditioner bracket that is fixed to the wall by expansion bolts later.

[0055] (4) Ensuring the performance of MiC building units while protecting their aesthetics (integrity advantage): ① Ensure the thermal insulation performance of MiC walls: The embedded columns are equipped with a second installation cavity and tongue and groove, which can ensure that the insulation cotton does not shift during the concrete pouring process, avoid the insulation layer formed by the insulation cotton being damaged into thermal bridges, and ensure the thermal insulation performance of MiC walls.

[0056] ② Protects the aesthetics of the MiC wall exterior: Completely avoids drilling holes in the finished wall surface, ensuring the high precision of the MiC wall after successful prefabrication in the factory, and guaranteeing the integrity and aesthetics of the MiC wall.

[0057] ③ Smooth pipeline laying: The pre-embedded pipe sections are reserved during the production stage of MiC building units, which ensures that subsequent air conditioning refrigerant pipes, power lines and other pipelines can be laid smoothly inside the MiC walls. This avoids the problem of structural damage caused by later slotting and laying pipelines in the MiC walls, and reduces the difficulty of pipeline laying.

[0058] (5) Versatility and adaptability (application advantages): ① High adaptability: "The second crossbeam of the air conditioner bracket can be adjusted to connect with the longitudinal beam, and the air conditioner outdoor unit can be adjusted to connect with the second crossbeam." This design allows the device to flexibly adapt to the installation of air conditioner outdoor units of different sizes and models on the market, making it highly versatile.

[0059] (6) Durability and ease of maintenance (long-term advantage): ① Reduce corrosion risk: The air conditioner bracket is connected to the outer end plate by the first bolt (i.e., high-strength bolt), which avoids the risk of corrosion at the welding point.

[0060] ②Easy to maintain and replace: The air conditioner bracket is connected to the outer end plate by bolts, which facilitates the disassembly and assembly of the air conditioner bracket and the maintenance and replacement of the air conditioner bracket; the air conditioner is connected to the air conditioner bracket by bolts, which facilitates the disassembly and assembly of the air conditioner and the maintenance and replacement of the air conditioner.

[0061] (7) Significantly improved fire safety (safety advantage): ① Fire barrier: The fireproof and heat-insulating coating in the invention patent CN110862748B is applied to the air conditioner frame. In the event of a fire, it can effectively block high temperatures, delay the softening and failure time of the steel structure air conditioner frame, and greatly reduce the risk of the air conditioner unit falling due to high temperature deformation of the air conditioner frame, thus buying valuable time for personnel evacuation and fire rescue.

[0062] (8) In line with green building principles (environmental advantages): ① Reduce on-site pollution: The air conditioner bracket is connected to the outer end plate by bolts, which greatly reduces the noise, dust and exhaust gas generated by on-site welding.

[0063] ② Promote the development of the construction industry: The pre-embedded components are integrated with MiC building units, which is highly compatible with the standardized, industrialized, and prefabricated construction mode of MiC buildings, and is conducive to promoting the development of the construction industry.
