detailed info for honeycomb panel
Construction for editing
1, personnel preparation: installation of 2 workers, porters 2 people, welders 1.
2 tools: electric hammer, the hammer 1, 1, activities, fixed wrench the 2, 2 meters on foot 1 to 1 square, plumb bob, 2, wire brush 1, drill 2, vigorously clamp 2, "+" word screwdriver 2 to 1, glue gun the ash, 1 knives, tape 1, red and blue pencil 2, 1 sets of electric welding machine, level 1.
Construction on the line
1, structural column verticality is positive, the keel in the installation position axis plumb line, record the data for each square measurement point, the average amplification, 10 mm.
2, the axis position with red and blue pencil on the floor well logo, with a square 90 degrees extension lead zoned out, the relative position of the axis, a positive error above keel.
Upright installation
1, link angle with anti-corrosion glue plus side gaskets, spring washers, plus fixed on bolt and keel twist.
2, the keel is docking identifies the location, temporary fixed spot welding machine.
3, on foot by 2 metres vertical error correction keel ± 2 mm, to three-dimensional adjustment so far.
4, check the diameter, on line method is compared with the.
5, full welding machine and embedded parts contact position, requirements for welding of high 6-8 mm, smooth lines, there are bubbles and inclusions are not allowed.
6 to two times, rust, antirust paint coating.
The beam installation
1, according to the construction drawings marked position grid beam axis.
2, the angle according to the mark bit welded.
3, the beam is arranged on the two codes, fine-tuning to import and upright surface.
4, a positive level and import position.
5, full welding.
6, two times to rust antirust paint coating.
Hanging board
The horizontal and vertical axis and the principle of identification upright beam center, adjust the curved plate according to the design of glue, the entire unit pillar package finished, then as a whole is positive, ensure lower lattice, vertical and flatness error in 2 mm, all the screws up.
Glue clean
1, the aluminum honeycomb plate protective film flanging part apart, according to 90 degree angle edge paste textured paper. Masking paper in the "+" glue joints shall be folded into 90 degree angle, the entire plate masking a place, force swinger, avoid textured paper crease.
2, packing foam round beech, requirements compacting straight.
3, glue in a straight line, from top to bottom, from left to right, once after.
4, scraping by injecting principles should also be one in the end, in the "+" word interface Guala speed slightly slower.
5 remove textured paper, into outward inclined 45 DEG pull, tear the paper into the trash, avoid the pollution of the environment.
6, weather resistant glue dry, off the protective film is torn, with a dry cloth to be surrounded by dust.
Workmanship details
Compared with the single aluminum plate: a honeycomb aluminum Max board can do 1500mm * 4500mm, because the board itself as a composite material, aluminum honeycomb interior provides guarantee for the board itself bear its own body weight, make the plate itself does not need to add any reinforcement. While the ordinary single aluminum plate in the width is greater than 1m or greater than 2m in length must join the stiffeners in plate behind. Stiffener welding in the plate on the back, because the stiffener and plate itself is the coefficient of thermal expansion is not the same, the thermal change several times, the front plate can appear uneven phenomenon. And this phenomenon is usually in the project after the completion of a half to one year began to appear.
Single aluminum plate belongs to a single product, process is relatively simple, powerful modeling ability, but the accuracy is poor; honeycomb panel for composite products, processing capacity and speed is weak, but the precision is guaranteed.
A honeycomb aluminum is the cover system, a rubber joint exposed and hidden glue two systems are available, the system fully consider the impact on the surface of the heat expansion and cold contraction, four directions can be freely telescopic board, effectively avoids the temperature stress on the surface roughness effect.
Single plate only glue joint exposure system, and the installation is installed code fixed keel, no suitable space release temperature stress, leading to surface prone to warping.
Honeycomb panel for composite sheet material, has the advantages of light weight, high strength, good flatness, surface, easy installation, easy maintenance, environmental protection is good, can be reused, excellent performance of anti heat expansion and cold contraction.
Aluminum single plate is a common non composite plate, compared with the honeycomb board, do not have the advantage, but in contrast, the cost of 3MM thick aluminum single plate usually takes 15 ~ 20% lower than that of 25MM honeycomb panel. Because of the weight and molding, building use less 4MM thick aluminum plate, and the cost and the thickness of aluminum honeycomb panel product veneer differ only in about 5%.
Edit 4 Technology
Roll forming technology
In the process of making panel and the backboard, need to board edge folding, folding machine which is used in traditional technology, because disposable fast folding, will be formed on the metal internal stress, and can form micro damage to inner metal, affect the service life of the metal. While the rolling forming technology is the use of ten roller, gradually will board edge folding to a preset angle, gradually forming the internal stress release, and the metal itself damage down to the minimum.
Continuous pre coating technique
In the aluminum roll forming can be attached to the top of the color of the coating technology, coating adhesion, good durability, uniform color, the same batch of products without any color.
