Structural performance test of precast components and performance test of heat transfer coefficient of sandwich thermal insulation external wall panel.

“the first brother” of Chinese real estate, Vanke has put forward the new word “housing industrialization”.

Connecting pieces: every 10000 pieces is an acceptance batch.

The detailed design of precast wall includes: detailed design: the detailed design of precast laminated plate includes the design of flue duct opening, lifting point embedment, electric box embedment and plate edge groove.

Housing industrialization refers to the use of modern industrial means and modern industrial organizations to achieve the standardization of buildings through the integration of technical means and systematic integration of various production factors at all stages of housing industrialization.

Grouting sleeve (in production): 500 joints are one acceptance batch 3.5.

Construction planning: according to the characteristics of precast structure, the project has carried out detailed planning for the site layout, tower crane anchorage, external ladder installation, accessories and tools, component storage and other items before construction.

Establishment of industrialization implementation team and company: establishment of housing industrialization project research team, mainly planning the construction technology, quality and production plan of industrialized housing.

The main planning content of the construction unit: “tower crane type selection, component storage, reinforcement positioning, tool design, support system, component installation process” and other pre-industrial planning work to ensure the implementation of the latter.

Responsibilities of the tool and accessory construction unit: entrust the on-site supervision unit to produce the first piece of components for acceptance of the first section of component installation.

Reinforcement and cement: mobilization retest (GB50204) 3.2.

Zhang Haisong…

If it is impossible to avoid mixing different kinds of fulcrums, the fulcrums shall be in the same position at the lower layer.
.

The maximum number of vertically stacked components in each group is 5; There are two fulcrums and the lifting points are not in the same position; Each board is padded with four fulcrums; Four fulcrums are also provided for the six lifting points; Note: avoid stacking different types together, which may cause cracks in the laminated plate due to different positions of fulcrums.

The anchor steel plate is reserved at the cast-in-place node at the west anchor point, and the east anchor point is set in the room.

The cast-in-place node embedded steel beam is used for anchoring.

The component template drawing, reinforcement drawing, water and electricity civil engineering reserved and embedded drawing, etc.

3 process inspection 3.4.

Site layout: the site roads meet the requirements of large component vehicles for transportation.

Amount of cast-in-place concrete 63.46m ³。 The second part: the preliminary planning of the project, the preliminary planning of housing industrialization, mainly includes [the planning of the preliminary preparation stage] and [the planning of the use stage].

Rubber Recess Former

Insulation board: one inspection lot per 5000 square meters, one retest per batch 3.3.

required by the review design shall be purchased, and inspection and management of mobilization materials, reinforcement sleeve connection joints, concrete strength, etc.

16) 1.

The practice of housing industrialization has helped Vanke further consolidate its position as a leader in the industry.

Materials such as reinforcement, insulation board, grouting sleeve, etc.

Part III: Mid-term implementation of component mobilization and inspection: when the component is mobilized, the foreman of the project building number shall organize the materials, quality, actual measurement and technology to jointly carry out the joint acceptance of the component appearance, quality, size and other items, including 12 civil engineering acceptance items and 5 water and electricity acceptance items.

In order to coordinate with the construction, the installation of the external ladder takes advantage of the features of simple lines and accurate installation dimensions of the precast housing.

The tower crane adopts the method of non-cast-in-place node anchoring.

shall be signed and confirmed by the static design unit.

Take the precast component produced by Vanke as an example, its length and width error shall not exceed 2mm, and the surface flatness deviation shall be less than 0.1%.

In order to save the site and reduce the cost of storage rack, the project has designed the overall precast wall plug-in frame to place the precast wall in a centralized manner before the precast wall enters the site.

Concrete: 100m per work shift ³、 One set of test blocks shall be reserved.

This precast component is cast in the factory at one time and is not easy to crack.

Responsibilities of the component factory: (BJF No.

The performance of tower crane shall meet the layout requirements of component unloading area and storage area.

Allocation of professional teams: according to the construction process, the project will be equipped with professional construction teams, and carry out professional training for lifting, grouting and other types of work to ensure that they are employed with certificates.

Grouting sleeve (before use): grouting material and sleeve are from the same manufacturer.

Part I: Residential Vanke Industrialized Residence Introduction Jinyu Huafu Fully Assembled Industrialized High-rise Residence Project, with a total height of about 80 meters and 27 floors, is the highest fully assembled residence built in the country at present.

Deepening design: Before the construction of precast residential building, the project will deepen the design of components from the perspective of production, construction and other parties involved in the construction.

Component production process: conduct concealed acceptance for thread processing, joint connection, number of connectors, etc.

After the installation of the outer elevator car, the distance from the balcony to the south is only 250mm, and the double-row platform frame is completely removed.

What we want to share today is the whole process of planning and construction of the “Residential Vanke Jinyu Huafu Industrialized High-rise Residence”, hoping to provide reference and inspiration to the peers.

The project has two floors underground and 27 floors above the ground, with a total construction area of 11838 ㎡, a total height of 79.85 m, a single floor area of 395.05 ㎡, a floor height of 2.9 m, two stairs and four households, and the trapezoidal building is a scissors ladder.

The production plan of precast components shall be prepared, and the technical quality assurance measures shall be defined, and shall be implemented after being approved by the person in charge of the enterprise.

The tower crane anchors the wall of 2 # precast residential building as precast components.
