Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a light building machine double platform collaborative construction method. BACKGROUND

[0002] In the field of high-rise residential engineering construction, the collaborative efficiency of main structure construction and external facade decoration work, and the safety of high-altitude work are the core factors affecting the project duration, cost and construction quality. The traditional residential construction generally adopts the combination construction mode of floor type external frame / cantilever frame + high-altitude hanging basket, which has many technical defects that are difficult to overcome in practical application: The working procedure is seriously disconnected, and the duration is long: strictly following the one-way flow operation process of "main structure capping → external frame removal → hanging basket installation → external facade decoration", the main structure and external wall construction cannot be carried out in parallel, the single building construction cycle is long, and it is difficult to meet the efficient construction demand of large-scale residential projects; the safety hidden danger of high-altitude work is prominent: the external facade decoration adopts flexible hanging basket work, which is easy to sway and overturn under the influence of wind, and there are high-altitude falling, object striking and other major safety risks, and the protection system is weak, and the safety control is extremely difficult; the construction efficiency is low, and it is greatly affected by the environment: the working space of the hanging basket is small, the manual operation intensity is large, and the single working procedure operation efficiency is low; at the same time, the open-air work has no protection, and the construction cannot be carried out in bad weather such as rain, snow and strong wind, and the effective working time is seriously insufficient; the intelligentization and integration level is low: the traditional frame body only has basic protection and work functions, and has no integrated modules such as maintenance, material distribution, dust reduction and sunshade, and cannot realize factory-like and indoor working environment; the safety of the support system is poor: the building machine / frame support directly acts on the floor, there is no special backstop reinforcement structure, which is easy to cause floor cracking and frame settlement, and the stress safety of large-tonnage frame cannot be guaranteed; the cost investment is high: the external frame erection, removal and turnover material consumption are large, the hanging basket needs a large number of manual cooperation, the vertical transportation frequency is high, and the material loss and labor cost are high.

[0003] In order to solve the above industry pain points, it is urgent to develop a light building machine double platform work technology which can realize synchronous interpenetration of main body and external wall construction, safe and controllable high-altitude work, intelligent integration and stable support, so as to promote the transformation of residential construction to high efficiency, safety, intelligence and green. SUMMARY

[0004] The purpose of the present application is to solve the above problems, and provide a light building machine double platform collaborative construction method, which realizes synchronous interpenetration of main body and external wall construction, safe and controllable high-altitude work, intelligent integration and stable support.

[0005] In order to solve the above technical problems, the present application adopts the following technical scheme: a light building machine double platform collaborative construction method, comprising the following steps: S1. Construction preparation: According to the building structure requirements, complete the load-bearing capacity calculation and backfilling and fixing of the basement roof slab in the building support area. S2. Building construction machine assembly: A lightweight building construction machine is assembled at the target building site. The building construction machine is equipped with an upper working platform and a lower working platform. S3. Implement dual-platform vertical overlapping operations: The main structure construction and exterior wall base pretreatment are carried out simultaneously on the upper platform, and the exterior facade decoration construction is carried out simultaneously on the lower platform. S4. Lifting Construction: After the single-floor operation is completed, control the simultaneous lifting of the two platforms and repeat steps S3-S4 to carry out the overlapping construction operations. S5. Cleaning and finishing: After construction is completed, dismantle the building machine in sequence and clean up the site.

[0006] Furthermore, the bearing capacity verification in step S1 shall be performed in accordance with the current building structure load code, and the reaction force of the support column of the building machine shall be calculated. The backfilling reinforcement involves using structural columns for rigid backfilling of the south-side columns, while the remaining columns are backfilled using disc-lock scaffolding. The disc-lock scaffolding is erected according to preset spacing and step distance, and the top of the uprights is supported by top supports and pads.

[0007] Furthermore, the upper platform covers four continuous structural layers, vertically divided into an overhead operation layer, a rebar binding layer, a concrete pouring layer, and a curing and formwork removal layer. The current structural layer is being reinforced with steel bars, installed with formwork, and poured with concrete. Simultaneously, the lower multi-layer structural layers are being demolded, the base layer is being cleaned, bolt holes are being sealed, and waterproofing is being pre-treated.

[0008] Furthermore, the lower platform is a segmented, independently operating structure, divided into construction sections along the horizontal direction, allowing multiple shifts to work simultaneously in an assembly line, sequentially completing plastering and leveling, insulation laying, waterproofing construction, primer application, and topcoat application.

[0009] Furthermore, the dual platforms adopt electro-hydraulic direct drive synchronous lifting, and the lifting process is monitored in real time by sensors for platform height difference, tilt angle and load data; When the monitored data exceeds the preset safety threshold, it will automatically correct the deviation; if it exceeds the warning threshold, it will apply emergency braking and sound and light alarms.

[0010] Furthermore, both platforms are equipped with dual anti-fall interlocking control logic: in normal lifting and lowering conditions, the motor brake self-locks; in abnormal conditions, the mechanical anti-fall mechanism is triggered, and the two mechanisms work together to lock the platform.

[0011] Furthermore, the building construction machine integrates spray curing, intelligent fabric laying, canopy shading, and dust suppression modules, with corresponding modules activated during the main body pouring, curing, and outdoor operation stages. The main construction of the upper platform and the decoration construction of the lower platform are controlled independently and carried out simultaneously.

[0012] Furthermore, in step S4, a meteorological safety check is performed before the jacking operation, and jacking is prohibited by interlocking under adverse weather conditions; After the jacking is in place, the braking device is locked, and the next process can only proceed after the joint acceptance inspection is passed. Each overlapping process must undergo a closed-loop acceptance process, and the finishing work can only be handed over after the basic acceptance is qualified.

[0013] Furthermore, the building construction machine and the construction elevator are deployed in a shared rail manner, and the two operate in coordination according to a preset logic to achieve efficient linkage of personnel, materials and platform operations.

[0014] Furthermore, in step S5, the building machine adopts a segmented dismantling method, first going up the platform and then down, first the auxiliary systems and then the core structure. The dismantling process is fully enclosed and under surveillance, and throwing components from high altitudes is prohibited.

[0015] The beneficial effects of this invention are reflected in: The invention proposes a dual-platform collaborative construction method for lightweight building construction machines, which can shorten the overall construction period of a single building, reduce labor costs, reduce material waste, completely eliminate safety hazards of high-altitude operations, and significantly improve the consistency of construction quality. The device is lightweight and modular in design, easy to assemble and disassemble, and highly adaptable, fully meeting the lean construction needs of modern residential projects for high efficiency, safety, intelligence, and greenness.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figs. 1-2 This invention discloses a construction method for a lightweight building construction machine with dual platforms working collaboratively. It is applicable to mid-rise and high-rise residential projects (including commercial housing, resettlement housing, and affordable housing) with 10 floors or more. By independently controlling the upper and lower platforms of the lightweight building construction machine, synchronously lifting, and vertically interleaving operations, the construction of the main structure and the exterior decoration can be carried out in parallel. This completely solves the technical problems of traditional construction procedures being disconnected, the construction period being lengthy, the high risk of high-altitude operations, the low level of intelligence, and the unsafe support.

[0019] Specifically, the following steps are included: S1. Construction preparation: According to the building structure requirements, complete the load-bearing capacity calculation and backfilling and fixing of the basement roof slab in the building support area. S2. Building construction machine assembly: A lightweight building construction machine is assembled at the target building site. The building construction machine is equipped with an upper working platform and a lower working platform. S3. Implement dual-platform vertical overlapping operations: The main structure construction and exterior wall base pretreatment are carried out simultaneously on the upper platform, and the exterior facade decoration construction is carried out simultaneously on the lower platform. S4. Lifting Construction: After the single-floor operation is completed, control the simultaneous lifting of the two platforms and repeat steps S3-S4 to carry out the overlapping construction operations. S5. Cleaning and finishing: After construction is completed, dismantle the building machine in sequence and clean up the site.

[0020] In step S1, the specific procedure is to perform a load-bearing capacity calculation on the basement roof slab of the building construction machine support area according to the "Code for Design of Building Structures" GB50009 and the "Standard for Design of Steel Structures" GB50017 before construction. In one embodiment, the total weight of the lightweight building construction machine is about 500t, and a total of 17 support columns are arranged. Among them, the maximum support reaction force of column #6 is 70t (including safety margin), and the support reaction force of the remaining columns is 60t (including safety margin). Only after the calculation is qualified can the backfill reinforcement construction be carried out. The reinforcement of the roof adopts a differentiated rigid support process. The five columns on the south side are rigidly reinforced with 300mm×300mm reinforced concrete structural columns. The remaining column area uses φ48.3mm disc-lock scaffolding for reinforcement. The longitudinal and transverse spacing of the disc-lock scaffolding uprights is 600mm, the horizontal bar step distance is 1500mm, and the ground level bar is ≤550mm above the ground. U-shaped supports are installed at the top of the uprights, and 40mm×80mm wooden pads are laid to ensure uniform stress distribution and stable reliability of the support system. Support positioning is completed after acceptance. Simultaneously, technical, equipment, and site preparations are completed. A specialized construction plan is prepared and technical briefings are conducted. The building machine's support system, power system, lifting system, and safety system are inspected and repaired. A W6017 tower crane and an 80t truck crane are used for hoisting operations. Material storage areas, equipment assembly areas, and safety warning areas are designated. The positioning and installation of embedded parts are completed.

[0021] After completing the support positioning and construction preparation in step S1, step S2 is carried out. The lightweight building construction machine is assembled using ground splicing and segmented hoisting methods. The installation sequence strictly follows: installing the base → installing the upper platform bracket → installing the standard section → installing the lower platform drive → installing the upper platform drive → installing the steel platform → installing the auxiliary functional modules. The assembled lightweight building construction machine features a double-layer structure with an upper and lower working platform. The upper working platform is the working layer for the main structure and exterior wall pretreatment, while the lower working platform is the dedicated working layer for exterior facade decoration. Both platforms adopt a modular and lightweight design, relying on the same support and lifting system for coordinated operation. The overall structure is highly rigid, lightweight, and easy to assemble and disassemble.

[0022] Step S3 involves the following steps: After the building construction machine is assembled and debugged, a dual-platform vertical overlapping operation is implemented. This step is the core construction method, adopting a parallel vertical operation mode for the main structure and exterior wall decoration, and a dual-platform synchronous operation mode, completely breaking the traditional serial process of "constructing the exterior wall after the main structure is capped". The upper platform covers four continuous structural layers with a total height of 13.45m (7 external scaffolding steps). Vertically, it is divided into four functional zones: the elevated operation layer, the rebar binding layer, the concrete pouring layer, and the curing and formwork removal layer. At the current benchmark structural layer (N layer), rebar support, formwork installation, and concrete pouring are carried out simultaneously. The intelligent concrete placing machine integrated into the building construction machine is used to complete the efficient concrete placement, reducing the pump disassembly and assembly time. At the lower multi-layer structural layers (N-1, N-2, N-3 layers), formwork removal, wall base cleaning, bolt hole sealing, and waterproof pretreatment are carried out simultaneously, achieving seamless connection between the main structure and the exterior wall base treatment. After concrete pouring, an integrated spray curing module is activated for fully automated moisturizing curing, eliminating the need for manual watering and improving curing quality and efficiency. The lower platform is a segmented, independently operating structure, divided into multiple construction sections along the building's horizontal direction. Multiple shifts work simultaneously in a continuous flow. After the upper platform's exterior wall base passes inspection, plastering, insulation board installation, waterproofing, and primer application are carried out sequentially on the lower platform. During the platform's descent and demolition phase, the stone-like paint topcoat and detailed opening repairs are completed simultaneously. The lower platform is protected by a fully enclosed rigid enclosure. A dust suppression module is activated concurrently during operations, eliminating dust pollution and the risk of falling objects, completely replacing traditional suspended platform work. The upper platform's main structure construction and the lower platform's exterior decoration use independent control logic, allowing for separate adjustments to the work rhythm without interference, enabling simultaneous and vertically integrated progress of main structure construction and decoration work.

[0023] Step S4 is as follows: After all single-floor operations are completed and accepted, the electro-hydraulic direct-drive synchronous jacking system is activated to control the simultaneous jacking of the two platforms to the designated position on the next floor. A standard floor height of 3m can be jacked in as little as 5 minutes, demonstrating high efficiency and stable operation. During the jacking process, displacement sensors, tilt sensors, and load sensors monitor the platform's operating status in real time. When the height difference between columns is ≤5mm, the system automatically corrects the deviation. When the height difference between columns is >30mm, the platform tilt angle is >0.5°, or the load exceeds 1.1 times the rated load, the system immediately applies emergency braking and issues an audible and visual alarm. All monitoring data is uploaded to the cloud in real time for remote monitoring and early warning. A meteorological safety check is performed before jacking operations. In wind speeds ≥6, rainy or snowy weather, or foggy weather, the system interlocks to prohibit jacking operations, ensuring jacking safety. Once the platform is in place, the braking device must be locked immediately. Only after the joint acceptance by the construction unit, the development unit, and the supervision unit can the next round of overlapping construction work begin. All overlapping procedures must be subject to a closed-loop acceptance process. The lower platform can only be handed over for decoration after the exterior wall base has been accepted. The platform can only be lifted after the finished decoration has been accepted. During the construction of a single building, the double-platform overlapping operation → synchronous lifting process is executed cyclically until the main structure and exterior decoration are completed.

[0024] Both platforms are equipped with dual anti-fall interlocking control logic, achieving zero risk in high-altitude operations. Under normal lifting conditions, the motor-operated brake self-locking mechanism activates in real time to prevent the platform from slipping or sliding. In abnormal conditions such as power outages, gas outages, overloads, or equipment malfunctions, the rack and pinion mechanical anti-fall mechanism is immediately triggered, locking the platform in conjunction with the motor-operated brake self-locking mechanism, thus eliminating the risk of platform falls and overturning at the source. Both platforms employ fully enclosed rigid protection on their working surfaces, completely replacing flexible suspended platforms and increasing the safety factor for high-altitude operations by over 90%.

[0025] The building construction machine integrates four major functional modules: spray curing, intelligent material placement, canopy shading, and dust suppression. These modules are activated according to the construction stage. The intelligent material placement module is activated during the main concrete pouring stage to achieve precise concrete placement. The spray curing module is activated during the concrete curing stage for fully automatic moisturizing and curing. The canopy shading and dust suppression modules are activated during outdoor open-air operations to create an indoor and factory-like working environment, extend the effective working time, and reduce the impact of severe weather.

[0026] The building construction machine and the construction elevator are deployed in a shared rail manner. The two operate in coordination according to a preset logic. The construction elevator is responsible for the vertical and efficient transportation of workers and construction materials, while the two platforms are responsible for the main structure and exterior wall construction operations. The two work together to reduce the frequency of vertical transportation, improve the overall construction efficiency, and achieve seamless connection between personnel, materials and platform operations.

[0027] Finally, in step S5, after the main structure and exterior decoration are completed, dismantling is carried out in sections according to the principle of upper platform first, lower platform second, and auxiliary systems first, core structure third. First, auxiliary functional modules such as sprinklers, sunshades, and fabric are dismantled; then the upper platform steel platform and hanging structure are dismantled; subsequently, the lower platform and drive system are dismantled; finally, the supporting columns, standard sections, and base are dismantled. An 80t truck crane is used for hoisting operations during the dismantling process. A fully enclosed warning area is set up at the construction site, with dedicated personnel monitoring the work. Throwing components from heights is strictly prohibited. Dismantled parts are categorized, cleaned, and transported in a standardized manner. After construction is completed, the construction site is thoroughly cleaned, the site is restored to its original state, and as-built documentation is compiled, completing the entire construction process.

[0028] The construction method described in this embodiment shortens the overall construction period of a single building by 12% to 15%, reduces labor costs by 50%, reduces material waste by 30%, completely eliminates safety hazards of high-altitude operations, significantly improves the consistency of construction quality, and features a lightweight and modular design that is easy to assemble and disassemble and highly adaptable, fully meeting the lean construction needs of modern residential projects for high efficiency, safety, intelligence, and greenness.

If the specific posture changes, the directional indicators will also change accordingly.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
