Hidden dangers of hidden projects are invisible to the naked eye and cannot be discovered immediately. But they are like a time bomb and can be detonated at any time. In fact, as long as we have mastered the basic norms of construction and understand the details that are most easily overlooked during construction, we will be able to shut out hidden dangers during construction supervision. Q: Hydro-retrofitting - accidentally pulled out the terrible reinforcement wall <<<Links: How to Avoid Overbooking and Remedy Question: The renovation plan has passed and preparations have been made for renovation. The first is hydropower reform. As soon as the first day of construction can be completed, the workers will pull out large and small steel bars. As we all know, the steel bars in concrete houses are like the skeleton of the human body. The reinforcements are broken and the house is fractured. solution: 1, designers must do a full survey, can not rely solely on floor plan design. 2. Before construction, ask the construction house for the distribution map of hydropower and determine which walls cannot be removed. 3, non-bearing wall can not be barbaric construction, vigorously knocking on the wall will cause damage to other joints, should be removed by block cutting. 4. Seriously deal with the structural faults that are formed after the demolition. Otherwise, wall problems and wall problems may be caused in the future. 5. Immediately after the destruction of the steel bar, the construction shall be stopped. Consult relevant technical personnel to assess the impact of the destruction on the house and reasonably repair and modify it. Q: leaking toilet (bathroom) solution: 1, the waterproof coating must choose the high quality, the good has the high stretchability to be possible to avoid the phenomenon that the temperature changes the wall to crack. That is, it can maintain its own viscosity, and can be firmly combined with the ground floor to form a stable impermeable layer. 2, before doing waterproofing, the ground should be cleaned first, with waterproof coating on the ground evenly coated 2 - 3 times, can not have empty drums, blisters cracks. 3, after brushing waterproof should pay attention to protect the ground, to avoid damage caused by construction. 4. Do not arbitrarily move the original floor drain and riser position of the bathroom during the renovation, and avoid changing the other rooms to the bathroom without authorization. Slots and pipes are not allowed to be run on the floor of the bathroom. 5. The seams between the bathroom wall and the ground and the seam between the upper and lower water pipes and the ground, and the place around the riser are the most vulnerable to water leakage. The construction must be brushed in place. 6, the best use of wet floor tiles bathroom floor, paving must be used to suppress the floor tiles bricks. 7, before the overall waterproof, should be done in the bathroom for 48 hours closed water experiments to determine the embryonic embryo no leakage point. 8, after the destruction of the bathroom waterproof layer is only partial repair is not enough, the new waterproof layer can not be closed with the old waterproof layer, cracks between the leak or will lead to the best overall re-waterproof. Q: Ignore the pressure test Question: The decoration has just ended up leaking water pipes. The tiles have to be removed and re-maintained. Where are the problems? 1. When doing the pressure test, first connect the hot and cold water pipes with a hose to ensure that the cold and hot water are pressed at the same time; install a pressure suppressor to prevent the air in the pipe from falling out so that the entire circuit is full of water; 2. Close the water meter and the outside gate valve and press it until the working pressure is 1.5 times that of 30. No leakage occurs. The pressure gauge shows that the pressure drop is within 0.05 MP. 3. Prior to the construction of the waterway, it is necessary to design in advance the location of water-related electrical facilities, such as water purifiers, water heaters, toilets, and wash basins. 4, determine in advance the type of water heater to buy, to avoid repeated construction. Two tests before and after the transformation: Before the construction, a pressure test shall be conducted to check whether the quality of the original water pipe buried in the house is qualified. It is better to have the property personnel present during the test. After the construction of the waterway, the water pipe shall be pressured to test the bearing capacity of the pipeline. Q: There is noise on the phone and the old line is dropped Question: There are always noises on the phone, watching television images are blurred, and accidentally dropped when surfing the Internet. Where does this trouble come from? 1. Telephone lines, cable television lines and other weak points should be worn separately in circuit construction. 2. Between the weak points, the distance between weak and strong electricity is not less than 30--50CM. 3, the network cable can not be in series: the wiring is best to use the regular manufacturers of five types of shielded cable, do not use 8-core cable instead, poor quality cable will cause signal attenuation, reduce network speed. (Distribution of hubs is not required for the distribution network cable. Although the wiring is convenient, the signal loss will be greatly increased in the future.) Q: I want to change the new wire - how can the old line not pull out Question: Want to change the new wire, but how can the old line not squeeze? (There are too many traces in the same casing, they are entangled with each other, or they turn dead when they run, and there is a phenomenon that it is difficult to pull out. There is also a case where the casing itself is of poor quality and it is buried in the wall. This will happen too.) 1, each pipe can not be threaded within more than 4, the line can not be tangled parallel to the trend. When it comes to the line, use the distribution box and leave the access port if necessary. 2. The wire bushing should be of a good quality and hardness hard PVC hose, able to withstand the pressure generated in the wall or ground. 3, the wire is prohibited within the pipeline connector Q: The home appliance tripped after it was fully turned on Question: Staying in your new home, ask a large group of friends to play. You enthusiastically opened the air conditioner, refrigerator, and stereo in your home. Suddenly all the electrical appliances “strikes†and the meter trips. solution: 1. Large-scale electric appliances that use large amounts of electricity should leave power outlets alone. Frequent trips are harmful to televisions, computers, and air-conditioning appliances. Care should be taken to avoid them. 2. After the completion of the circuit construction, a 24-hour full-load operation test shall be performed. All electrical appliances shall be turned on and used after inspection. Large electric appliances such as refrigerators, microwave ovens, and water heaters have large input power, and they must be routed individually when they are rebuilt, and cannot be shared with other appliances. Otherwise it is easy to trip and power off when it is turned on at the same time. Charges to households are overloaded, and the capacity cannot meet the electrical requirements of so many electrical appliances at the same time. This can also lead to tripping accidents. Q: The floor drain does not deodorise Question: One of the most troubling problems in bathroom renovation is the toilet floor drain and anti-odor. Eating and watching TV in the living room can always smell a stench, which is caused by a problem with floor drains, an important part of the bathroom. solution: 1, the toilet must be installed anti-odor floor drain. Anti-odor floor drain seal and water seal two. Sealing: Rely on the attraction force of the magnet to suck the lid to achieve the effect of isolating the odor. Water seal: It has a water trap, which prevents the back of the sewer from returning due to the sealing effect of water. The sealing effect is better. 4, because the floor drain is to be embedded in the cement, should not be replaced, it is recommended to choose the full copper floor drain. Stainless steel to choose zinc is relatively thick to avoid rust. Do not use PVC for aging. 5, the washing machine into the water to use a dedicated washing machine floor drain, this floor drain rotation control, when not rotating can be closed. Do not use the water seal too deep in the washing machine, otherwise the water flow will be too quick and easy to overflow. Q: Double control switch is very important Question: Many people find that after the renovation, the house is getting bigger and bigger, and the more inconvenient it is to live. For example, the large bedroom only had a switch at the entrance, forgot to install double control, and it would be inconvenient to have to go to bed and turn off the lights. 1, in the family need to install the dual control switch where the following places; bedroom lights, preferably in the bed and the door separate control; long channel light source, at both ends of the channel to leave a control switch; step up and down Light source, stairway lighting to install double control switch at both ends of the step. Using a fluorescent switch can be easily used in a dark passage. 2, in the bathroom next to the best reserved telephone line. 3, to reserve the socket to consider the future of furniture furnishings, or most of the socket are behind the furniture can not be used, equal to do nothing. 4. With the development of science and technology, the role of the Internet in people's lives is increasingly important. When decorating home, it is best to keep a few nets at home, such as in restaurants, bedrooms, and study rooms. Internet access at any time to achieve home office. If you like to surf the internet on the sun-drenched terrace, you can also lead the cable to the terrace. 5. It is advisable to reserve a power socket in the balcony, corridor, stairs, and cloakroom. Home circuit design must take into account the ease of use of future life. Before the construction, it is necessary to repeatedly simulate the living conditions after the check-in and plan the functional requirements of each room one by one. Otherwise, it was really the beginning of the construction. It was rushed forward by the construction period. The circuit layout of all the houses was often decided in a matter of days or two. It was inevitable that there would be omissions and regrets. For example, when a phone ringing in a comfortable bathtub suddenly rings, and the bathroom is not installed, then the connection is not received or not, and the leisurely mood is swept away. The bright restaurant is comfortable but it is not eaten. Law watching TV and so on, similar problems are easily overlooked circuit layout problems.

Across the pond, you will find the Deutsches Institute fur Normung (DIN) flange specification, consisting of a variety of European styles which have been unified into one code for the purpose of commonality. Designation as a DIN Flange by the German Institute of Standardization assures the user of design quality the way an ASME flange would here in America. Although much less common than ANSI/ASME steel flanges in the United States, many of our international customers request flanges to these specifications for a variety of applications such as imported steel vessels, cargo ships, and other infrastructure which may consist of metric pipes/valves and European designed equipment.
The subset flanges under the DIN standard consist of the same style of flanges in the United States, including the most commonly used slip on flanges, weld neck, flanges, and blind flanges. Adapter flanges can be custom made to end user requirements for the mating of American flanges to international ones, however we find it is a much more common and easy solution to provide DIN flanges to mate to existing equipment.
The most common metric type flanges fall under the following categories:
DIN 2501 through 2503 for flat ring flanges
DIN 2512 through 2519 for alternate face flanges
DIN 2627 through 2633 for weld neck flanges
DIN 2641 through 2642 for lap joint flanges
DIN 2565 through 2569 for threaded/companion flanges
DIN 2527 for blind flanges

Question: The beautiful bathroom is finally done, but the first time you come downstairs to find a door, your home's dirty water leaked to my roof! Not only was it a waste of time wasting experience, but at the same time neighbors became tense. (Leakage reasons: 1 The quality of waterproof material is poor 2 There is no drainage slope left on the toilet floor 3 The waterproof layer is destroyed in the later period of construction.)
Reminder: waterproof must be done, you can sprinkle a layer of sand after finishing, after the tiling will be a good point, if you do not do a good job of waterproofing, then in the future if there is a leak, you have to knock out the tiles to repair more trouble.

solution:
3, the kitchen and toilet where water is often used to use waterproof sockets, to avoid short circuit power after pouring water. The kitchen switch is best installed on the open side wall outside the room.
4. Keep the pipeline in the kitchen away from gas stoves and other heat sources.
5. Frequent power failures require professionals to check whether the outlet is in poor contact or not. If there is a shortage of capacitance in the power box, increase the capacity if necessary.
TIPS:
2, try to select the depth of the water storage tank, water seal height of 5CM to the best effect of floor drain odor.
3, water seal floor drain water stored once the water can not play a deodorant effect, so in the dry season to use more water spills.
