- Q: Where should I pay attention to the formwork?
- In the case of cast in place multi-storey houses and structures, the method of segmental formwork shall be adopted, and the upper formwork and its support shall be installed and shall meet the following requirements:The lower floor shall bear the load-bearing capacity of the upper layer or support with the support;The column of the upper bracket shall be used for the column of the lower layer bracket and the padding plate shall be laid;When the suspension formwork and truss formwork method are adopted, the supporting capacity and stiffness of the supporting structure must meet the requirements.
- Q: What is the name of the wire above the train?
- The catenary provides 25 thousand volt power frequency alternating current for the locomotive, according to the locomotive model difference, adopts the direct step-down, the frequency conversion power supply or the AC and DC conversion power supply, this is mainly for the speed regulation convenience.
- Q: Why do not different kinds or different sizes of slings and slings are used together?
- Choose proper slings and slings according to the specific conditions of the heavy loads; no heavy weights are allowed to be attached directly with the hooks, and no different kinds are allowed
- Q: What does the inspection of rigging involve?
- The crane used in atmospheric environment, preferably manganese phosphide coating, steel wire rope, heavy corrosive environment, preferred hot-dip galvanized double phosphating steel wire rope, priority wire rope in sea water. Please note that at the time of purchase, in the purchase invoice must indicate the name of wire rope, such as phosphate coated wire rope or 316 stainless steel wire rope, prevent illegal infringement of their legitimate rights and interests of enterprises, to counterfeit products in addition, patent products are generally in the rope on the outer packing is patent spraying mark, warranty book should be the main technical indicators, such as the phosphating film type and weight (film has an important influence on the weight of phosphating film size, wear resistance and corrosion resistance of the service life of the wire rope, for reference only)
- Q: What torture refers to the lever and the sling
- This is a torture peculiar to china. The knee joint has the smallest range in the major joints of the limbs, and the length of both ends of the thigh and leg is favorable to the prisoners. The lever principle is used to compel the victims with lesser intensity. Key points of anti joint using tiger stool:1, the victims in the sitting position (arms tied or tied into the penalty, the pulling force cross) it will aggravate the leg ligament, and supine position due to hip joint ligament relaxation, legs relaxed, will weaken the degree of pain;2, the leg is tied in the lap of the thigh, rather than the following parts. Because the function of the tiger stool is to pull the joints and ligaments of the victim's leg and to cause a dislocated knee, not to break the victim's leg. Because the broken leg, the fibula needs a lot of power, the pain time is short (the victim will soon fainted), do not meet the punishment, both to torture the victims and their own labor saving requirements.According to records, when the victim is on a tiger stool, he usually gets sweaty when he pad three bricks. When the five bricks are completely dislocated, the person will faint. The torturer usually each brick will be suspended for a while, the victims of the pain continued for a period of time after aggravated torture efforts. Women's ligaments are usually softer than men, so they suffer longer on tiger stools and tend to faint when they are added to six bricks, the longest of which is eight bricks.
- Q: What are the precautions for rigging in hoisting works?
- When lifting heavy objects, heavy is prohibited to stand.
- Q: How do you tie the wire rope?
- The price of phosphating coating wire rope is higher than that of smooth steel wire rope, but the unit use cost is lower than the smooth steel wire rope. The test data indicate that fatigue life of phosphating coating steel wire rope is 3-4 times of plain steel wire rope, wire rope life and fatigue life is proportional to, according to the current market price of roughly wire rope, manganese phosphating coating of steel wire rope although the price is higher than that of plain steel wire rope, and prolonging the service life of much higher than the rate of price increase so, the phosphating coating steel wire rope, the average daily cost of using only smooth steel wire rope 30-45%, longer service life, lower cost per use, stability and security in the process of using and more cost-effective products, light surface wire rope upgrade, for reference only
- Q: What are the installation steps for crane beams?
- The crane beam and track shall be corrected after the main component is fixed. Fix immediately after correction, in order of fixation, bolt first and then weld.
- Q: Why are the suspension bridges a main cable, even a n multi sling, not a bridge directly from the tower?
- The main weight of a bridge is not the car or train on it, but the road itself, that is, the road we see. Now let's analyze this:We analyze it with a pylon. The two sides of the pylon are symmetrical stay cables which connect the main beam of the pylon through the stay cables. Now suppose that only two towers on both sides of the cable, symmetrical each one of the two cables subjected to beam gravity, two symmetrical of the cable along the direction of the force, according to the stress analysis, the stress can be decomposed into a horizontal and vertical force to a downward force a vertical force; and the same on the right side of the force can be decomposed into the right level of a downward force; the two force is symmetrical, so the two level of the left and right horizontal force cancel each other out,
- Q: Does the pressing rope have any influence on the tension value of the wire rope?
- According to the current market price of the phosphating coating steel wire rope, phosphating coating steel wire rope daily use cost is just plain steel wire rope about thirty percent of phosphating coating steel wire rope is a substitute for plain steel wire rope upgrade, for reference only.
