Aluminum veneer construction technology, aluminum veneer construction plan

Aluminum plate curtain wall installation method:

1. Pay-off. According to the axis and elevation line on the main structure, the installation position line of the supporting skeleton is accurately bounced to the main structure according to the design requirements, so as to provide a basis for the installation of bone addition.

2. Install the connectors.

The connector is welded and fixed with the embedded parts on the main structure. When there is no embedded iron part buried on the main structure, the expansion bolt can be punched on the main structure to fix with the connecting iron.

3. Install the skeleton.

According to the position of the elastic line, the steel skeleton with anti-rust treatment is welded or bolted to the connector. The elevation and centerline position should be checked at all times during installation. For the skeleton vertical rod of the aluminum plate curtain wall of the outer wall with a large area and high floor height, it must be measured with a measuring instrument and a line pendant, and its position must be corrected to ensure that the skeleton vertical rod is straight and flat.

4. Install the aluminum plate.

Use rivets or bolts to fix the aluminum alloy plate veneer on the section steel skeleton block by piece. Leave a gap of 10 15mm between the plates in order to adjust the installation error.

5. Plate seam treatment.

The gaps between the aluminum plates are waterproofed by pressing with rubber strips or injected with elastic materials such as silicone sealant.

6. Expansion joint treatment.

The expansion joints of the aluminum panel curtain wall must meet the design requirements. The treatment of expansion joints generally uses neoprene molding tape with good elasticity to press into the seam edge anchor to connect and seal.

7. Curtain wall closing treatment.

Handle the curtain wall closure according to the design requirements. It is also possible to use the edge closing plate formed by the aluminum plate to cover all the square pipes and connecting fixtures at the edge of the wall, and the connectors installed by the wall panel can be used for anchoring and bolted to ensure the appearance.

8. Board surface cleaning.

Remove the adhesive paper and clean the board.

<> construction process of imitation wood grain aluminum veneer.

1. The method of leaving seams for imitation wood grain aluminum veneer is to leave a seam of the same size between the board and the board, and then fill it with foam strips and sealant, which can effectively avoid rainwater infiltration, and can also avoid the thermal expansion and contraction deformation of aluminum veneer. Process flow of aluminum veneer device: pay-off, connector of fixed skeleton, fixed skeleton, installation of aluminum veneer, closing structure disposal and inspection.

Second, the imitation wood grain aluminum veneer dense assembly device is a dense combination device between the board and the board, as long as a natural seam visually, mostly used in indoor walls and ceilings, the accuracy of the device is higher than that of the exterior wall device, so it is necessary to ensure the correctness of the aluminum veneer dense assembly device. Process flow of aluminum veneer device: pay-off, connector of fixed skeleton, fixed skeleton, installation of aluminum veneer, closing structure disposal and inspection.

3. The dry-hanging device of imitation wood grain aluminum veneer shall determine the device status of the aluminum veneer support skeleton according to the design drawings and the measured dimensions on site. Fitting to fix the skeleton. The position of the fixed skeleton and the device skeleton should be precise and the combination should be strong.

Aluminum veneer installation process:

1. Skeleton installation.

1) After the aluminum plate curtain wall completes the façade grid pay-off work, the rear anchorage is adopted at the edge of the structural beam at the support, that is, the backward cut anchor bolt of M10*110 is first driven into the galvanized steel bottom code. Then weld the enterprise code, connect the square pipe with the steel code through the stainless steel hexagonal head bolt of M10*110, and after the correction is completed, the sawed cross column is installed on the main column, and the cross material is installed on one side by fixed welding connection, and the other side is connected by movable support to ensure sufficient deformation. Finally, all welded steel components should be removed after welding slag, coated with anti-rust zinc-rich paint.

2) After the skeleton is installed, the concealed items will be installed according to the drawing, all screw holes and nail holes are drilled on site, and the installed screws must be squeezed with weather-resistant glue on the screw heads.

2. Aluminum plate customization.

1) After the skeleton is installed, the design technician will draw the aluminum plate processing drawing according to the actual size of the pay-off, determine its model, specification, quantity, and surface treatment requirements, and then the purchaser will contact the processing matters.

2) The manufacturer carries out shearing, punching, folding, drilling, nailing, welding angles, glue potting, and reinforcing rib forming according to the aluminum plate processing and forming drawing. Then after grinding, pre-treatment, drying, primer, topcoat, and covering, oil picking, cooling, and the processed aluminum plate is packed after passing the inspection, and then transported to the construction site for installation.

3. After the experience of the aluminum plate hanging aluminum plate process is qualified, the control line is installed on the steel keel. Then, after the processed aluminum plate is moved to the designated position according to the model, it is connected with the skeleton with self-drilling and self-tapping screws, and after being adjusted and leveled with the upper and lower left and right, it enters the next process.

4. Before gluing and gluing, xylene should be used to clean the surface of the glue road material, and wipe it dry with a clean white cloth before volatilization, and then fill in the foaming rubber strip of appropriate size (the rubber strip should be filled in and no longer deformed), and after pasting the masking paper along the glue road, the sealant is filled. The glue seam should be kept full and not reused, and then the glue path should be hung flat with a special small hanging knife, and finally the masking paper should be carefully torn off, taking care not to pollute the surface of the aluminum plate.

The processing of aluminum veneer has the following processes:

Aluminum veneer processing process:

1.Design and draw the part diagram of its sheet metal parts, also known as three views. Its function is to express the structure of its sheet metal parts in the form of drawings.

2.Draw a diagram. That is, a part with a complex structure is turned into a flat part.

3.There are many ways to cut materials, mainly in the following ways:

1) Shearing machine cutting. It is the length and width of the shape cut out by using a shearing machine. If there is punching and corner cutting, then turn the punch to combine the mold punching and corner cutting.

The thickness of the aluminum veneer that can be processed by our company's shearing machine is steel plate. The length is less than 4 meters, and 3 to 4 people need to operate when the raw material is sheared, and the board surface is raised flat and hands are grasped by grasping the plate. ）

2) Punch cutting. It is to use a punch press to punch and shape the flat part structure after the part on the plate in one or more steps. It has the advantage of short man-hours, high efficiency, and reduced processing costs, and is often used in mass production.

CNC punch in the mold with the cooperation can punch out some special shape of the hollow effect, our company used CNC punch HP-2500 can process the width of 1530 within the width of the aluminum plate.

3) CNC engraving machine cutting. When the CNC engraving machine is unloaded, the first thing to do is to write the CNC machining program. It is to use programming software to write the drawn diagram into a program that can be recognized by CNC machining machines.

Let it follow these procedures step by step on an aluminum plate, and punch out the structural shape of the flat part. When processing, we should pay attention to how to typeset more reasonably and save materials. Our company's CNC engraving machine can process aluminum plates with a range of 2m*.

3.Punching. It is to use a punch press to punch out the corresponding hole position on the aluminum plate according to the drawing, so that the corner code can be installed during assembly. When processing, pay attention to whether the hole spacing and hole margin are correct.

Sheet metal engineering: metal plate, shearing, scribing, opening angle, bending, arc rolling, argon arc welding, grinding, assembly, polishing, quality inspection, qualified.

Spraying engineering: pendant, acid degreasing, washing, alkali etching, washing, polishing, washing, chrome, washing, pure washing, drying, spraying primer, leveling, spraying topcoat, leveling, spraying varnish, baking, quality inspection, qualified.

2) Use a soft cloth soaked in water-diluted detergent to gently wipe the board surface (3) Then rinse the board surface with plenty of water to wash away the stolen goods.

Hyperbolic aluminum veneer is one of the most complex processes in decorative metal curtain wall materials, and it is the highest difficulty in the aluminum veneer processing industry.

1. Adopt appropriate technology according to different curvature and plate shape.

2. Make templates according to drawings.

3. First, use a four-roller rounding machine in the X direction to make a round according to the single curved plate process, and then use local 4 and part point welding in the Y direction to bend the plate surface to the required radian.

5. The preliminarily formed workpiece is inspected according to the template, and the local place is corrected for the second time.

6. Welding is carried out on the installation side around the perimeter.

7. For special hyperbolic plates, open die hydroforming or drawing molding can be adopted.

Hyperboloid aluminum veneer technology is perfect, and a variety of special-shaped plates can be made according to customer needs.

Twisted aluminum square tubes.

1. Install the corners according to the same horizontal height.

2. There are different skeletons according to different requirements, such as: L50*50*5mm angle steel fixing, embedded aluminum pendant fixing, etc., according to different products have different fixing methods.

3. The hanging parts pre-installed on the gusset keel, together with the gusset keel, are closely attached to the light steel keel in a vertical direction under the light steel keel, and the spacing of the gusset keel is determined according to the size of the plate type, and must be adjusted to the level after all installations.

4. Buckle the gusset plate on the keel in order, press down the inverted lock piece after each buckle is completed, and connect the keel with the connector when connecting.

5. Gloves must be worn when installing the board surface, if you accidentally leave fingerprints or stains, you can use dish soap to clean and wipe dry.
