The aluminum mold unit generally takes about 45 days from structural optimization to aluminum mold transportation to the site.
The chief engineer of the project tracks the design content and progress in time, and organizes joint review, which is reviewed by the chief engineer of the branch company.
The work flow of aluminum formwork implementation should be arranged compactly, and communicate with the construction unit, design unit and aluminum alloy formwork subcontractor in time.
Structural optimization 3.1 in order to meet the requirements of no plastering, the external wall structure should be designed as a full cast-in-place concrete wall to avoid masonry.
General requirements 1.1 the scope of application of aluminum alloy formwork is particularly applicable to concrete structure buildings with standard floors of more than 25 floors and external walls designed for internal insulation, and the floor height should be less than 3.3m.
The aluminum mold unit shall rectify and adjust in time according to the acceptance opinions.
The aluminum formwork processing has high requirements for the accuracy of the reserved position of the I-beam, and the construction is difficult, which affects the construction period.
Once changed, it will have a great impact on the construction period and cost.
The general contractor shall reasonably plan the stacking site to avoid material loss.
Attached with the inspection and acceptance form, the project department shall organize the relevant personnel of the construction unit, the supervision unit, the design unit, the technical center of the group company, the engineering management center and the branch company to conduct acceptance on site.
After the re inspection is qualified, all parties shall sign for confirmation and retain the relevant acceptance image data.
The material mobilization shall be organized for acceptance according to the list.
2.4.1 special terms requiring contract interpretation 1) scope of contracting; 2) construction period; 3) clarify the model of aluminum alloy, the date when the aluminum alloy formwork enters the construction site and the product quality; 4) clarify the delivery time of drawing joint review, deepen the design and production cycle; 5) clarify the support and reinforcement system in the quotation; 6) clarify the range, quantity, specification and model of auxiliary materials, such as the number of release agent, embedded parts and split screw casing; 7) promised reuse times; Provide professional guidance of the manufacturer and workers’ disclosure and training; 8) modification cost of aluminum formwork after change; Recycling and treatment of aluminum alloy formwork after use; 9) phased capital payment proportion; 10) Raw material quality standard and acceptance; 11) Pre assembly quality standard and acceptance; 12) Site installation quality standards and acceptance; 13) The quality standard of finished concrete shall be indicated to ensure that it can be handed over to the coating unit for acceptance; 14) Scope and duration of warranty for aluminum alloy formwork; 15) Definition of auxiliary labor, such as mortar plugging, hole plugging, wrong platform repair, measurement and setting out, etc.
2.2 joint review of construction drawings the construction unit, the design unit, the general contractor and the aluminum alloy formwork subcontractor shall jointly review the drawings, and make corresponding image data and records.
The project department shall provide a warehouse for placement of auxiliary materials and accessories to prevent material loss.
2.8 the aluminum mold unit that transports to the site shall number the aluminum mold that has passed the trial assembly acceptance, pack it according to the on-site installation sequence, and timely deliver it to the project department in combination with the project schedule and deployment.
2.4 the contract shall be signed in accordance with the company’s model subcontract for aluminum alloy formwork, and the corresponding special terms shall be supplemented.
Therefore, it is not recommended to use section steel cantilever steel pipe external scaffold.
Except for partial distribution nails, other components (diagonal braces and embedded parts, vertical back ribs, upright rods, feeding ports, and tension screws) shall be assembled in full accordance with the requirements of the site implementation.
2.7 trial assembly and acceptance the aluminum mold unit shall conduct trial assembly of the aluminum mold in the factory according to the ratio of 1:1.
2.5 mold matching design and review aluminum alloy formwork subcontractors are responsible for professional design and reasonable mold matching.
Inspect the factories and projects under construction of aluminum alloy formwork manufacturers.
climbing frame), which can effectively reduce the structural holes, organize the alternate construction of various processes (the construction of external wall doors and windows, railings, putty, etc.
The project department shall plan the access route and formwork stacking site in advance.
Some work should be inserted in advance or carried out synchronously as far as possible.
2.
The structure, architectural design and building delivery standards cannot be modified or adjusted after being determined by all units.
(cooperate with the climbing frame to realize the reverse construction of the outer wall) 3.2 the walls of the elevator shaft and staircase should be designed as a full shear wall structure..
