In doing putty sanding, brick laying and door installation:
The project was also interspersed. In the main structure stage, exterior wall coating, doors and windows, railings, masonry, fine decoration and other operations are interspersed in advance to achieve flow construction:
At present, the exterior wall of the project is fully interspersed, and the interior decoration is under construction to deliver the model layer:
The interspersed construction is inseparable from the support of new process construction methods.
The Poly project applied
Poly develops aluminum mold five-piece set
– including
All cast-in-place exterior wall, aluminum mold, climbing frame, high-precision masonry, thin plastering five major processes.
1. The fully cast-in-place exterior wall realizes structural self-waterproofing, which can greatly reduce the leakage rate;
The exterior wall of the traditional craftsmanship part is made of masonry, and the masonry roof brick area and the window side are areas with high leakage. After using the fully cast-in-place exterior wall, according to the project’s test, the leakage rate of the exterior wall for 48 hours of continuous water exposure was very low:
2. The use of aluminum formwork improves the dimensional accuracy of the structure on the one hand, provides conditions for the exterior wall to be wipe-free, and reduces the risk of empty drum falling in the later stage of exterior wall plastering; On the other hand, the template can be reused, saving energy and reducing emissions. About 40% of the project’s aluminum formwork is reused, not brand new plates.
3. The use of climbing frame instead of traditional scaffolding, on the one hand, to create conditions for the interspersion of exterior walls and outdoor projects, improve the efficiency of project operation, fine decoration and outdoor projects can be inserted more than 3 months in advance;
4. High-precision masonry and thin plastering reduce the thickness of plastering to 5-8mm, and reduce the empty drum rate by more than 50%, which not only improves the safe and civilized image of on-site operation, saves energy and reduces emissions, but also greatly reduces the risk of cracking of empty drums in the later stage and ensures product quality.
At present, Poly Development has achieved 100% of the newly opened projects using aluminum mold five-piece sets.
In addition to the aluminum mold five-piece set, the project also applied a lot
Micro-innovative processes
For example, the concrete wall hydropower point is pre-embedded in place at one time. The hydropower points on the concrete wall, from the aluminum mold deepening and fully considered, the civil construction drawings are nested in hardcover drawings to ensure that they are accurately embedded in place at one time, avoiding late grooving, injury to structural safety and increasing the amount of work.
The openings of the exterior wall doors and windows are provided with grooves, and this “small height difference” formed on the inside and outside of the exterior doors and windows further reduces the hidden danger of leakage.
Finished water-stop section: solve the problem of traditional reserved pipe holes, and the hidden danger of leakage left by the root plugging after the installation of the riser. During the construction of the main structure of the building, the drainage riser waterstop section is pre-embedded, and then the riser is directly tightened with the waterstop joint lining when the riser is installed, reducing the risk of leakage between the pipe root and the coagulation:
The main structure of the project also adopts aluminum mold + climbing frame construction system.
The aluminum mold adopts pull tab + screw reinforcement system;
The beams and floor roof are installed as a whole:
Part of the exterior masonry was optimized during the aluminum mold design stage and realized
All-concrete façade structure
Some secondary structures at the door openings of the indoor rooms have also been optimized, using the form of lower hanging beams, and the main structure is poured at one time.
The hydropower pipeline adopts the form of embedded and grooved, and is formed at one time with the main body.
The embedded wire box adopts the fixed form of short steel bar and main steel bar welding, so that the embedded deviation of the wire box is small and the accuracy is high.
During the installation of the aluminum mold, the aluminum alloy sub-frame is fixed on the aluminum plate and the concrete is poured and formed at one time.
Masonry adopted
Fly ash sintered porous bricks
and
Autoclaved aerated concrete blocks
The combined form.
Fly ash sintered perforated bricks are used in watery spaces such as kitchens, bathrooms and exterior corridors:
The waterless space is built with autoclaved aerated concrete blocks:
Set up a “U” beam at the position of the electric box hole to avoid damaging the beam during the grooving process of the pipeline and affecting the overall quality of the masonry:
Hardcover
In terms of canopy ceiling, the ceiling restaurant adopts light steel keel combined with wooden keel (fireproof paint three times) skeleton plus a layer of flame retardant version and a layer of gypsum board surface, L-shaped cantilever lamp slot arrangement light strip and downlight, and the periphery is edged with bronze brushed stainless steel lines:
The corner of the light steel keel of the ceiling ceiling is provided with iron sheet knot to prevent cracking, the back side is partially reinforced with a flame retardant version with a length of not less than 200mm, the docking of the ceiling side plate ≥ 200 is connected by dovetail mortise, and the corner of the gypsum board is required to be made into an L-shaped shape to prevent cracking:
In terms of leakage prevention, all kitchen and bathroom rooms and balcony waterproof parts are inspected with the requirement of three times of closed water, namely: structural water closure, water closure after the completion of waterproof layer construction, and repeated inspection after the completion of the overall construction to ensure that leakage prevention is foolproof:
The waterproof of the kitchen and bathroom requires the wall rigid flexible waterproofing, the base layer is required to be cleaned in place before waterproof construction, the wall root is made R angle, the wall pipe and the wall yin and yang angle, the floor drain to do local waterproof strengthening treatment, the bathroom threshold stone to make the reverse bump protruding door hole 200mm, the shower room water barrier sills using water-stop steel plate (into the structural wall 1cm):

Among them, in terms of process acceptance, the system is divided into five stages of basement, main masonry, decoration and decoration, mechanical and electrical installation, and landscape engineering in the installation and construction cycle.
in order to
Acceptance of wall column reinforcement formwork in the main masonry construction stage
for example. First of all, after the on-site wall column steel bar construction is completed and the self-inspection is qualified, the constructor notifies the supervision engineer to come to the site for acceptance; After the supervisor arrives at the scene, use the APP to photograph the representative acceptance parts, enter the acceptance results, and then send a copy to the owner.
Using the APP process acceptance, on the one hand, let the management know the latest situation of the project in real time; On the other hand, massive acceptance data can be stored in the cloud, data can be traced, and the previous process acceptance data can still be queried in a targeted manner until delivery.
The project also uses the Mingyuan engineering quality inspection system, and the main structure adopts overall online control.
Pre-event control
That is, the construction of steel bars before concrete pouring, the size of the aluminum mold structure, the reinforcement details, the vertical flatness of the aluminum mold, the ceiling is extremely poor, etc., which are initiated and approved by the construction unit through the Mingyuan Engineering Quality Inspection APP, the supervision unit conducts full acceptance, and the construction unit conducts partial acceptance;
Control in the matter
That is, by monitoring the vertical flatness of the aluminum mold and the extreme difference of the roof plate during the concrete pouring process in real time, if there are unqualified points, the reinforcement treatment is carried out in time to ensure the quality of the concrete after forming;
Post-event control
That is, initiate the review meeting approval system on the Mingyuan Engineering Quality Inspection APP, find out the unqualified points, analyze the causes of the problem, and formulate corresponding improvement and strengthening measures;
