Aluminum plastic plate construction technology and process

1. Measure the construction stringing

1) According to the axis and elevation line of the main structure, the mounting position line of the supporting framework should be bounced onto the main structure accurately according to the design requirements.

2) Punch out all embedded parts and retest their size.

3) Distribution error should be controlled when measuring the wiring, not error accumulation.

4) The measurement of the construction stringing shall be carried out under the condition that the wind force is not greater than grade 4. Check the verticality of curtain wall and the position of column in time after the measurement.

aluminum wall panels


2. Install connectors and weld the connectors and embedded parts on the main structure. When the embedded iron parts are not embedded in the main structure, expansion bolts can be drilled into the main structure and fixed with the connecting iron parts.

3. Install the skeleton

1)According to the position of the spring line, fix the rustproof column on the connector with welding or bolt accurately. During installation, elevation and center line position should be checked at any time. For the frame columns of aluminum curtain wall with large area and high floor height, measuring instruments and wire drop must be used to measure and correct their positions, so as to ensure the vertical bar of the frame is straight and flat. Post installation elevation deviation should not be greater than 3㎜, before and after the axis deviation should not be greater than 2㎜, left and right deviation should not be greater than 3㎜; Elevation deviation between two columns should not be greater than 3㎜, namely pillar maximum elevation difference should not be greater than 5㎜, and the distance  deviation of the adjacent two root stand should not be greater than 2 mm.

2) Install the connectors and gaskets at both ends of the beam at the predetermined position of the column, and install them firmly with tight joints; The level deviation of the adjacent two beams shall not be greater than 1 mm. Same level elevation deviation: when a curtain wall width less than or equal to 35 m should not be greater than 5㎜; When a picture of a curtain wall width is greater than 35 m, it should not be greater than 7㎜.

4. Install aluminum sheet

The aluminum alloy plate finish is fixed on the section steel frame block by block by rivets or bolts according to the construction drawing. Board with board between seam is 10 ~ 15㎜, in order to adjust the installation error. When the metal plate is installed, the deviation of the top and bottom and the left and right sides should not be greater than 1.5㎜.

5.After cleaning the surface of the metal plate and frame with cleaning agent, immediately place the sealing strip or weatherproof rubber strip in the gap between aluminum plates, and then inject silicone weather-resistant sealant and other materials. The adhesive should be full and no gaps or bubbles are allowed.

6. Metal plate can be used to seal the end of the wall board and the keel for sealing treatment.

7.Processing deformation joint

processing deformation joint should satisfy the need of building expansion and settlement first, and also should achieve adornment effect at the same time. The shaped gold plate and neoprene belt system can be used.

aluminum wall panels


8.Clean the board surface clear adhesive paper on the board surface. Here are some of my three years of construction experience. The first thing to pay attention to is to adjust the size of the construction drawing according to the size of the site. If it is better that the drawing dimension deviation is not big, do not need to adjust, and just put the deviation on the final closing plate. If the deviation is big, you should divide again, as to add a divided or split, you should get a balance between the beauty and the utilization rate of embedded parts. 

First respect the cellular signal of architect. If the architect does not provide a detailed breakdown, then you should follow the architect's advice: you should decide the division of the building highlights the level division or the vertical division. The division should be close to the standard width of the board in order to improve the utilization. The processing size of aluminum plastic plate is limited by the aluminum skin. General manufacturers can only processing standard plate (the width of the board is 1220, and the length is free). If architect has a requirement to need large dimension cent case, that can order exceed wide board only (the domestic manufacturers who can produce are not many, and the price is very expensive).

The technology and the process of the Aluminum plastic plate construction

(1)According to the requirements of the design drawing, first draw a horizontal elevation on the wall and pop up the grid line. Nail wood wedge on the wall according to cent grid line. Wood wedge should make anticorrosive treatment,and the position of wood wedge should accord with the dimension that keel divides archives, horizontal and vertical space is 300mm commonly.

(2)Installation of base plate

1.Wooden keel moisture content should be less than 12% and it should be undertaken anticorrosive treatment first before the construction. The wooden keel that relies on a wall should be brushed anticorrosive oil completely 2 times, and then undertaken fire prevention treatment again. Use the fireproof coating to brush the wooden keel that does not rely on a wall or base course board for 2 times. Dry them before proceeding to the next step.

2.Before installation, check whether the flatness and verticality of the base wall are in line with the requirements. Meanwhile, check whether there is a gap between the base plate and the wall. The base plate must be nailed to each block.

(3) Quality requirements for wooden products

1. Flatness requirements: the basic level is required; Require the base line to be straight and square; Clean up the base. 2. Insert process of the veneering: the opposite side should be in the original plate edge; Straight around the corner. 3. After the requirements of smooth surface, the corner should be square, the lines should be clear and smooth.

(4) Installation of the surface layer of the plastic aluminum plate  1. Plastic aluminum plate features: economy - it can be ordered in batches according to customer requirements. With the progress of The Times, high-rise buildings bristling, the rise of personnel costs, people hope to save money in the long-term maintenance of the building, and aluminum plastic plate is in line with the needs of the outer decorative board. Durability -- aluminum plastic plate is made of aluminum material coated with durable fluorinated vinyl resin coating to maintain a beautiful appearance. It has durability, weather resistance, corrosion resistance, pollution resistance. Lightness - aluminum plastic plate uses lightweight aluminum and resin sandwich sheet, only six kilograms per square meter, because light and reduce the burden of handling, so that the installation operation is simple, and it can shorten the construction period. Flatness -- aluminum plastic plate has a high level of flatness required by exterior wall decoration. The use of flat aluminum layers and composite materials, through high-precision processing technology and strict quality control, makes it a warp-free decorative board. Modeling - aluminum plastic plate modeling, according to customer order requirements, in the range of manufacturing, the maximum limit of the design and modeling, can do bending processing, curve processing, notching processing and other complex processing, whether it is plane or curve surface can be stressed beautiful artisan design.

2. The installation of plastic aluminium plate: the condition that needs to have before acting the role of face plate installation and condole top paper face plasterboard installation are same. When installing, bump and scratch should be prohibited and the flatness should be consistent. The serious scratches and pollution on the surface of the plastic aluminum plate material: is  mainly because in the transportation and installation process, early tear off the surface protection film, and the surface is polluted by the glue and bump during the installation process.

The color difference of Aluminum plate : aluminum plate production and processing is carried out in batches, and each batch of paint ratio slightly changed, so it is easy to cause the existence of aluminum plate color difference. The color of aluminum plate must be checked whether the color of aluminum plate is consistent with the color of sealing sample before installation. At the same time you should check whether the aluminum plate surface quality is intact. Peripheral sealing: the peripheral sealing of plastic and aluminum plate installation is the part connected with other external mounting materials, which should be coordinated before installation. Otherwise, it is easy to cause uneven sealing adhesive seam or loose sealing.

1. Engineering measurement :(1) aluminum plate construction measurement shall be carried out according to the actual situation of the original matrix and the drawings. (2) according to the construction experience, the wind force is below grade 4, which is suitable for daily noon measurement and has a good effect. (3) according to the midpoint of the extended datum line, the deviation values of left and right positions of embedded parts are measured and recorded. (4) according to the elevation of each layer provided by the design drawing, the deviation of the embedded part elevation shall be measured and recorded. 2. After the aluminum plate is transported to each floor, the aluminum plate plate is discharged in a place that is not vulnerable to damage, so as to ensure that the aluminum plate plate is free from damage and pollution. 3. Aluminum plate installation should be carried out layer by layer upward. (1) carefully place each aluminum plate in the position to be installed, and then face the aluminum plate plate to the edge of the wall. (2) wipe the dust and dirt on the plate surface clean to avoid air leakage when acting on the suction cup and ensure the construction safety. (3) check the product quality of each aluminum plate plate to confirm whether its surface meets the requirements of the plate. (4) according to the design scheme, stainless steel bolts are used to connect the aluminum plate, and isolation plates are added. (5) insert two 8mm thick plates (or adjusted 9mm or 7mm thick plates) into the upper and lower ends of the vertical joint and close the mounting plate to ensure the vertical joint. (6) use 2m ruler to lean against the vertical surface, and pay attention to whether there are sundries on the vertical bar, and respectively correct its perpendicularity. (7) use a horizontal ruler against the horizontal material to check the horizontal condition. (8) clean around the plate, first use a clean dry brush to remove dust and impurities, and then use a blowing tool to repeatedly blow away the remaining dust. (9) dip a clean cotton wire into a solvent, such as methyl ethyl ketone or acetone or toluene, and scrub the plate and connect the four sides. (10) DC795 weathering adhesive shall be applied around the transverse material after the solvent volatilizes. The adhesive shall be applied without intermittent leakage and bubble, so as to ensure no possibility of water seepage. The appearance of the adhesive shall be noted, and the surface of aluminum plate shall not be contaminated. (11) after each unit plate is installed, the installation quality must be checked. (12) make installation self-inspection records.

3.2 Hang straight, set square, find rules, spring line:According to the requirement of design drawing and geometrical dimension above all, the metope that inserts stick metal to act the role of a panel needs to be hanged straight, cover square, look for a regulation and actual measurement and spring line. The size and quantity of decorative wall panels need to be determined.

3.3 Connecting parts for fixing the skeleton: the horizontal and vertical bars of the skeleton are fixed with the structure through connecting parts, and between the connecting parts and the structure, they can be welded firmly with the embedded parts of the structure, or the expansion bolts can be played on the wall. Because the latter method is more flexible, has smaller size error, and is easy to ensure the accuracy of position, it is often used in actual construction. Bolt position needs to be drawn line, and open a hole according to the line.

3.4 Fixed skeleton: its structure is shown in FIG. 9-8 and FIG. 9-9. The skeleton should be anticorrosive in advance. Install frame position accurately and firmly. After installation, check the center line and surface elevation comprehensively. For the exterior wall of high-rise building, in order to ensure the installation precision of decorative panel, it is advisable to use theodolite to connect the horizontal and vertical bars. Deformation joints and settlement joints should be properly handled.

3.5 Metal veneer installation: the installation sequence of wall panels is from the top of each wall vertically to the bottom of the first row, starting from the bottom up. After installing the first row of the wall, install the second row. After installing 10 rows of wallboards, the suspension line should be checked once to eliminate errors in time. In order to ensure the appearance of the wall quality, bolt position must be accurate, and the use of single-side construction hook bolts fixed, so that the bolt position horizontal horizontal vertical. Fixed metal ACTS the role of the method of face plate, commonly used basically have two kinds. One is to screw the strip or square plate to the section steel or wood frame, this method has a better durability, more used in external walls. Another kind is to stick slatting on tailormade keel, this law is used at indoor more.

The gap between the board and the board is generally 10 ~ 20mm, multi-purpose rubber strip or sealing arrow elastic material processing. When the decoration panel is installed, pay attention to the easy to be contaminated parts should be covered with plastic film protection. Easy to be scratched, touched parts, should be set up safety railings protection.

5.3 take care not to collide with the metal trim panel when removing the shelf.

6.Quality problems that should be paid attention to:

6.1 leakage: the main function of the decorative panel is not to leak, which should be guaranteed. Want to act the role of a face plate to rise from every installation above all, must go according to normative regulation strictly serious construction, especially the each place that receives a mouth to construct must handle well, quality checks a branch to check to want seasonable reach the designated position.

6.2 gluing and caulking: this is closely related to leakage. If it is not done well, it will cause great problems. According to incomplete statistic, make glue, embed seam to cause leakage and rework, take glass curtain wall, metal ACTS the role of face plate and aluminium alloy door window installation project quantity to make an appointment with 30%, it is the big head of quality of project of 3 kinds of exterior decoration, should take glue seriously accordingly, embed seam this one working procedure.

6.3 uneven and non-straight lattice joints: the main reason is that the actual size of the structure construction is not checked in accordance with the drawing size carefully before construction, and it is also caused by not fine bullet line, not straight tension line and not frequent inspection of suspension line.

6.4 dirty walls: the main reasons are various. One is the operation technology, that is, the bottom-up installation method and technology directly bring some difficulty to the protection of finished products. The higher the level, the greater the difficulty.
