Steel canopy is also commonplace in reality. Steel canopy is laminated with glass and other materials. It is formed in a firm frame of steel structure. It is bright, beautiful, and high in strength. It is widely used in office buildings, residential areas, shopping malls and underground areas. Entrances and exits such as garages. What are the advantages of steel canopy? The steel canopy changed the physical characteristics of the original glass and other materials. It has high requirements for construction and installation and requires a complete construction program. Let's take a look at how the steel canopy construction plan is done.
Steel canopy advantage
1. Seismic resistance: Most of the ground floor houses or villas are slope roofs. This type of roofing mechanism uses triangular roof trusses made of cold-formed steel structural parts. Light-weight steel members form after the sealing of structural plates and gypsum boards. A very strong "plate rib structure system", this type of structural system is very effective in seismic and horizontal load resistance.
2. Wind resistance: The weight of steel section structural buildings is relatively light, the strength is relatively high, and the overall steel is good. It can withstand winds of 60-70 meters per second and play a better protection role.
3, insulation: The main use of thermal insulation materials, has a good thermal insulation function.
4. Comfort: The steel structure adopts a high-efficiency energy-saving system and has excellent respiratory function, so that the air humidity in the house can be adjusted, and the roof has a good ventilation effect.
Steel canopy construction plan
1, processing preparation and cutting
According to the layout of the construction drawings, the amount of welding shrinkage and machining allowance shall be reserved when setting out and numbering materials, and the model shall be set according to the layout. Steel rectification: steel must be rectified before cutting. The rectified deviation should not exceed the allowable deviation specified in the specification to ensure the quality of the material. The hot-worked steel is first hot-worked, and then the hole is cooled after it is cooled. Steel plate embedded parts and other parts cutting drilling and spraying anti-corrosion paint treatment.
2. Measure and take off line: Measure the centerline of the elevation of the embedded parts according to the benchmark line of the civil construction elevation and check the elevation deviation and left and right deviation of the embedded parts. Organize the results and determine the adjustment and disposal plan for the embedded parts. Along the outer edge of the floor, pop the ink line to set the top mark of the embedded part.
3, embedded parts installation and processing: positioning embedded parts installation location, drilling installation. It is required that the embedded parts be accurately positioned and firmly embedded. The elevation deviation is not more than 9mm, and the left and right displacement is not more than 20mm.
4. Suspension arm installation and welding: The installation of the suspension arm adopts welding. It is necessary to inspect the welding node and adjust the design slope of the suspension arm so that it can be welded accurately. After the edge of a suspended arm is correct, install an additional suspension arm on the other side and position it to the correct spot. Then use the two suspension arms as a reference to pull out the highest and lowest elevation lines of the suspension arm and weld the remaining suspension arms one by one. Welding seamless steel tubes. When the profile steel needs to be long, weld the tip and straighten it. When using steel joints, in order to make the joint steel and the steel plate embedded parts close, the corner should be shoveled according to design requirements. Butt welds shall be welded on both ends of the weld, with the same material and shape as the weldment, and cut and flattened after welding.
5, calibration test: After the installation of the suspension arm first check the quality of the site connection. The installation quality of the suspension arm mainly checks the non-perpendicularity of the vertical surface of the suspension arm; the pressure is applied to the side of the vertical surface of the suspension arm; and the suspension arm slopes. Ensure that the suspension arm meets the design stress conditions and overall stability requirements.
6. Connect the cable: Position the rod reference line and elevation line, install embedded parts and weld the railing as required.
7, stainless steel glass claw mounting welding: according to the design of the size of the vertical and horizontal lines and design elevations, clamped with fixtures, positioning welding, assembly is completed, welding glass claw base.
8, anti-rust paint treatment: slag and splatter should be removed, stainless steel parts sprayed white paint multiple times anti-rust paint treatment. Coatings and film thickness shall comply with the design requirements or the provisions of the construction specification. The paint on the inside of the limb steel must not leak.
9, laminated glass processing and installation: According to the design requirements combined with the actual measurement size to determine the glass size, as well as the horizontal and vertical position, manufacturers processing production. Install stainless steel glass claws, adjust the glass after temporary fixing, adjust the standard horizontal, vertical, flat surface. The deviation must not exceed the specified deviation.
10, adjustment test: point glass for the overall adjustment test, adjust the standard horizontal, vertical, flat surface. The deviation must not exceed the specified deviation.
11, up and down plastic: fully clean the gap between the glass, there should be no water, grease, paint, rust, cement mortar, dust and so on. Clean the adhesive surface thoroughly and dry it. To adjust the depth of the seam, avoid three-sided adhesive. Stick protective tape on both sides of the seam to protect the glass from contamination. Up and down the sealant at the same time, after the injection of glue will smooth the surface of the glue, remove the excess glue. After filling, remove the protective paper and wipe the glass with solvent if necessary. Do not contaminate or scratch the adhesive until it has completely hardened.
12, repair test: partial repair test.
13. Glass cleaning: Make sure that all parts have no problem and then perform overall cleaning of glass dust. If necessary, wipe the glass with solvent and wait for acceptance.
