Mr. Huang of the city has recently purchased a new home and wants to renovate after the fall. Recently, he went to a number of interior design companies to find out, and some companies said that the design fee was waived, while others insisted on design fees. Mr. Huang felt quite confused about this. Home improvement companies proposed to provide customers with free designs and become an industry practice day by day. Then, what is the secret behind this "free design"? Insiders pointed out that some home improvement companies verbally agreed to waive the design fee, and the final decoration costs will not necessarily be reduced. They often use material rebates and additional procedures. Other ways to "rise" the project budget.
The income of some company designers is based on 2% to 3% of the output value of the designer's home improvement projects. In order to increase revenue, the designer will undoubtedly receive more orders, and therefore, rigorous construction is inevitable. For example, many companies provide free designs, and the so-called design proposals issued by their designers simply indicate the placement of furniture and other elements. There is not much design content at all.
In addition, "free design" is really free of charge? Industry sources said that because the traditional design fees are linked to the value of home improvement projects, therefore, many "design" has not been done according to the actual needs of customers, many superfluous The elements were then created, which increased material and labor costs. The "free" design fee was made up from here. In addition, there are also ways to make up for the design fee: the designer requires the consumer to purchase the building materials from the designated building materials store, and takes the rebates from it; in the budget list, the material units used are ambiguous; in the budget list, the actual usage of the main and auxiliary materials is not listed. The list of national standards for construction losses, etc., all add to the cost and expense.

Associated Standard Gb/t [1] . 1-2009 technical requirements for cold rolled cylindrical helical springs-part 1: Tension Springs; GB/T2087-2001 cylindrical helical spring dimensions and parameters: Gb/t 2008-1997, etc. . Design parameters specify material diameter (d) , outer diameter (D) , total length (Ho) , number of working rings (N) , location and shape of earrings, the load (P 1P 2... ... P I) and the corresponding value (H 1h 2... Hj) such as (figure 2) should be marked with Po if there is initial tension such as (figure 2) : features many different terminal devices or [Hooks"are used to ensure the tension source of the tension spring. A tension spring works in opposition to a Compression Spring. Compression Springs Act in the opposite direction when pressed, and tension springs act in the opposite direction when stretched or pulled apart. When the ends of the tension spring are pulled apart, the spring tries to pull them back together. Like compression springs, tension springs also absorb and store energy. But unlike compression springs, most tension springs are usually under a certain amount of tension, even without any load. This initial tension determines how tightly the tension spring is wound without any load. Application of medical respiratory equipment, motion control, medical mobile equipment, hand tools, home care equipment, shock absorption, pump springs, mechanical and electronic protection hardware, fluid control valves, mechanical aerospace components, actuators, switching equipment. Tension Springs, also known as helical tension springs, are generally of equal pitch and usually have a circular cross-section. They can be used in many situations, such as Production Assembly, Experiment, R & D, Maintenance and so on. The tension spring occupies an important position in the global market, widely used in national defense, marine, computer, electronics, automobile, mold, medicine, biochemistry, aerospace, railway, nuclear power, wind power, thermal power, engineering machinery, mining machinery, construction machinery, elevators and other fields.
