2 product features are generally standard The thickness of the standard plate is 100-300mm, the width is 600mm, and the height is adjusted according to the actual floor height of the building.

04 no transverse slotting: ALC plate has steel wire mesh or reinforcement mesh inside.

Considering safety, durability and integrity, transverse slotting is strictly prohibited.

To sum up, the current comprehensive cost is on the high side.

05 good fire resistance: ALC board is an inorganic non combustible material with good fire resistance, and there is no harmful gas overflow under high temperature and open fire.

On site dimension review of construction process → detailed design by BIM → mobilization of ALC plate → plate transportation to each floor → pipe clamp installation at the upper end of plate → plate in place installation → adjustment → fixed pipe clamp → plate joint repair → joint repair → cleaning → acceptance.

The buildings of each hospital are built according to their own needs and have their own uniqueness.

The maximum height is 6500mm.

ALC general plate is installed horizontally and vertically, and its notch is divided into Tu notch and C-type notch.

Combined with the situation after use, the proposed measures are put forward, that is, to control the design deviation and reduce the hidden danger of installation; Reasonably arrange the construction period and prepare the planning in advance; Standardize the design modulus and improve the application scope; Increase the promotion and application and reduce the use cost; Use BIM Technology to improve assembly effect.

They should be industrial technical workers who have received professional training.

06 no reduction of decorative layer: ALC light partition board realizes the assembly of traditional on-site wall building.

There are few factories and fewer high-quality manufacturers.

The application of precast technology in hospital construction the precast assembly rate of hospital buildings shall be specified in the planning conditions and land transfer conditions, and the total proportion of internal partition board, precast stair board and precast composite beam floor slab of the main structure in a single building will also have corresponding requirements.

In recent years, with the continuous improvement of environmental protection requirements, the precision and quality requirements of precast processing, and the improvement of site transfer construction management and technology, Shi Yuedong and Nantong First People’s Hospital have gradually increased their application in public buildings through the wide application of BIM and other information technology.

Combined with the practical application of ALC light partition wall and decorative integrated steel partition wall in our hospital, this paper introduces the basic situation of materials, construction technology, advantages and disadvantages and scope of application.

03 good thermal insulation: thermal conductivity λ= 0.16w / (m.k), heat storage coefficient s = 2.75w / (m.k).

Therefore, general hospital precast buildings are mainly applied locally in the standard floor of hospital wards and some standard consulting rooms.

In order to achieve the final design effect, the decorative layer still needs to be implemented..

As an enclosure material, especially as a reinforced plate, it is enough to meet the strength requirements for bending resistance, crack resistance, deformation and joints of wallboard under various service conditions.

There are deviations in the on-site installation of constructors, which is difficult for the supervision unit to supervise and manage, affecting the overall safety and durability.

In the later stage, cracks are easy to occur due to the influence of settlement, temperature and other changes, affecting the aesthetics, integrity and use function of wallboards.

The buildings of each hospital are built according to their own needs and have their own uniqueness.

Hospital buildings have their own particularity, such as wide layout, many departments, complex functions and many special requirements for medical technology.

Hospital buildings have their own particularity, such as wide layout, many departments, complex functions and many special requirements for medical technology.

The conventional thickness of the indoor standard ward is 200mm, the thickness is 600mm, and the maximum height is 6500mm; The consulting room adopts ALC plate with thickness of 100mm, thickness of 600mm and maximum height of 4000mm.

4 advantages: light weight, high strength, multiple environmental protection, thermal insulation, sound insulation, respiratory humidity regulation, fire prevention, rapid construction and so on.

03 imperfect installation specifications: at present, the installation specifications are all industrial specifications and lack of national unified specifications.

Application of ALC lightweight partition materials in hospital buildings 1 basic situation autoclaved lightweight aerated concrete (ALC) plate refers to a high-performance homogeneous porous silicate plate made of cement, quartz sand and lime as main raw materials, added with foaming agent and cured by high-pressure steam.

ALC light partition board is a new environmental protection material encouraged to be used and promoted at present.

5 shortcomings 01 corners are easy to be damaged: they are easy to be damaged during transportation, loading and unloading and installation.

Hospitals generally use c-notch vertical installation, and only use horizontal installation above door and window openings.

The installation and construction personnel are different from ordinary bricklayers.

(a5.0 and B06 are selected for the project) 02 high strength: cube compressive strength ≥ 5.0mpa, and the bonding force between reinforcement and ALC material after special rust prevention is > 1.0MPa.

06 good durability: ALC board is an inorganic silicate material with no aging and good durability.

02 cracks are easy to occur at the joints: if no special repair agent is used for the connection between plates and the connection between plates and other structures, the construction quality is not in place and the supervision is not in place.

04 good sound insulation: ALC board has greater quality advantages than other lightweight materials, especially its mesostructure is composed of a large number of uniform and unconnected micro pores, which has excellent energy consumption of absorbing and consuming sound waves, so it has good sound insulation.

3.

According to the specification requirements, there must be corresponding protective layer on the outside, and the thickness of the plate itself is relatively thin.

05 the comprehensive unit price is on the high side: ALC light partition board is also a new wallboard material.

Therefore, general hospital precast buildings are mainly applied locally in the standard floor of hospital wards and some standard consulting rooms.

Reinforcement mesh treated with anti rust and anti-corrosion technology is set inside the plate, which can meet different structural design requirements.

01 light unit weight: the absolute dry unit weight shall not be greater than 625kg / m ³， It can effectively reduce the dead weight of the building, and also reduce the size and amount of structural members.
