Detailed Product Description: | Beijing professional to do the attic ride compartment (mezzanine) two-story indoor plus layer 68603923 professional undertake: Interior sashes, facade added layer, facade of housing thermocline ceilinged, casting slab production, villa renovation, housing renovation, concrete plus-story building separated layer. Our company is a regular cast-in-place concrete barrier enterprise, quality guaranteed. Situ compartment advantages: occupied storeys space is relatively small, better sound and heat insulation, without shaking sensation; equal 70 years of useful life and the main structure of the original house. Beijing professional attic making the attic install a Beijing steel structures attic making Beijing steel structures attic structures Beijing steel structure order attic install steel structures attic installation welding: before welding inspection → Preheat rust → assembly and welding pad and arc board → before welding welding → test (1) Check the bevel angle, blunt edge, gap, and the amount of the wrong mouth, groove and on both sides of the rust, oil, iron skin should be cleaned. (2) warm-up: before welding gas welding or specially roasted gun uniform heating of the groove and the base metal on both sides of each of the 100mm range, the measured temperature and surface temperature measurement, to prevent the temperature does not meet the requirements or partial surface oxidation, pre- heating temperature. (3) re-examine the preheat temperature, such as inadequate temperatures should be re-heated, to meet the requirements. (4) assembly and welding pad and arc plate, surface cleanliness requirements the same as the surface of the groove, pad and base metal snapping arc welding of plate and base metal should be firm. (5) welding: the first layer of weld bead should seal the junction of the the groove base metal pad, then by-channel layer tired solder to fill the groove, and each weld after welding must be cleared slag and spatter, weld defects should be promptly rubbed off and repair. (6) an interface must be continuous welding is finished, as a last resort midway stop welding should insulation slow cooling process, the regulations should be re-heated again before welding. (7) in case of rain, the snow should stop welding, the component weld around and above should have windshield, canopy, wind speed greater than 5m / s should stop welding. Ambient temperature is below zero, should be required to take the measures of preheat and post-heat construction. (8) carbon structural steel in the weld cooled to ambient temperature, low-alloy structural steel inspection of weld inspection should be carried out after the completion of 24h. Steel structure determination in the difference between the light steel and heavy steel structure of heavy steel and light steel structure does not have a uniform standard, many experienced designers or project managers often can not fully understand, but we can be considering some data and to be judged: A: plant Driving lifting weight: greater than or equal to 25 tons, can be considered as the heavy steel structure. B: The amount of steel per square meter: greater than or equal to 50KG/M2, can be considered the heavy steel structure. C: The main components of steel plate thickness: greater than or equal to 10MM, light steel less. There are some reference value: cost per square meter, the maximum component weight, maximum span, structure, eaves higher these in determining whether a plant for heavy steel or light steel to provide empirical data, of course, many buildings are light, heavy steel have. But we can be more sure of heavy steel: such as: petrochemical plant facilities, power plant plant, large span stadiums, exhibition centers, high-rise or high-rise steel structure. In fact the national normative and technical documents and no heavy steel one that might be called, for the difference between the light building steel structure, general steel structure for the "ordinary steel more appropriate. Because a very wide range of ordinary steel structure can contain a variety of steel structures, regardless of load size, even including many of the light steel structure, the light housing steel structure technical regulations just for its "light" and provides for more specific The content and scope only confined to the single-layer portal frame. Light steel is a vague term, generally in two ways. Existing steel structure design specification "(GBJ 17-88) in Chapter XI bar, small angle steel light steel structure, round and less than L45 * 4 and L56 * 36 * 4 light steel structure made of angle iron, lack of years in the steel used in the manufacture of small structures should not use reinforced concrete structure, the now basically little used, so basically tend to get rid of this revision of the design of steel structures. Can be seen, the points of light steel and heavy steel is not the structure itself, the severity, and the severity of the exposure cladding, structural design concept or welcome new and old customers advice cooperation · purpose: customer satisfaction dedication to quality projects, corporate earnings and the company mission: to return Social · goal: to master the state-of-the-art technology to provide first-class service and building a first-class project, create a first-class environment and corporate strategy: the special and fine; improve the comprehensive competitiveness, to attract high-end customers. ; related diversification. Business philosophy: at a competitive cost, fast and efficient for customers to provide quality services. The customer's smile is the best return, continuous improvement and development of the company's core competitiveness. · Values: lowering the cost and increasing efficiency and quality objectives: customer satisfaction rate of 100%, the year zero complaints informally engineering size, as long as necessary, we immediately went to the reasonable price!
