Q: What is the effect of concrete pouring on the construction quality?: Our usual way is to fight the fuse.

Q: Will the embedded stove why use stainless steel corrugated hose connection?: The construction of the scaffolding of this project is subject to the requirements of the relevant sections of the latest JGJ130-2011 "Safety Code for Construction Fastener Steel Scaffolding" To design and calculation, the preparation of special safety construction program, after the implementation of the approval. The preparation of the steel pipe should be selected first vertical and horizontal spacing and horizontal bar step, only these are determined in order to calculate the amount of steel pipe.

Q: How to optimize the construction management to improve the quality of construction projects: I suggest you look at Google, there will be a lot, I hope you can find a satisfactory, I wish you a happy life!

Q: I am sorry to see your answer on Google, can I also pass a copy of my construction and decoration project?: The difference between a flexible pipe and a rigid pipe is that the flexible pipe causes a change in the temperature of the working fluid due to the fluid or medium in the pipe or the temperature of the working environment, resulting in expansion and expansion of the pipe, causing some changes in the pipe itself, Within the scope of the pipeline itself will not cause damage. Such as plastic pipes, metal pipes. Rigid, such as concrete pipes, such as flues, exhaust shafts. Gas and heat is definitely a metal tube.

Q: On the classification of car repair, the best details Thank you Such as sheet metal workers, car circuits, etc. Thank you: There are also special materials such as bamboo, so rare, no longer introduced

Q: How to effectively deepen the construction process management to improve the quality of construction projects: Steel is good, it is best stainless steel, aluminum alloy for a long time easy to deformation, organizational structure is very bad!

Q: What is the difference between a rigid pipe and a flexible pipe, what kind of pipe is rigid, what is flexible: Tower crane is used to lift objects up and down the lifting of the object is not clear the length of the arm of the tower crane!

Q: Is the clamp type flexible connector connected to the pipe to the rubber pad?: Construction safety inspection standards (JGJ59-2011) a total of 19 inspection items, they are 1. Safety Management 2. Civilized construction. Fastener steel scaffold 4. Door steel scaffold 5. Bowl button steel pipe scaffolding 6. Socket type plate fastener type steel scaffolding 7. Full house scaffolding 8. Suspended scaffolding 9. Attachment lift scaffolding 10. High operating basket 11. Foundation Pit Engineering. Template holder 13. High work 14. Construction electricity 15. Ingredients Red Chrysanthemum Chrysanthemum Chrysanthemum. Construction lift 17. Tower crane 18. Lifting hoisting. Construction tools hope to help you.

Q: Is the flexible sleeve of the broken wall used as a second retest?: The national standard is 18kg. Color steel sandwich panel is a common product in the current building materials, do not chu chu dumpling seal festival over the extinguished Long can only be a good flame retardant and environmentally friendly and efficient. Caigang sandwich board has two layers of metal panels and the middle of the polymer core insulation from the suppression. With the installation is simple, light and efficient light and efficient features. And the filling system used to close the molecular structure of the closed, you can put an end to the condensation of water vapor.

Q: Maintenance Skills of Leakage of Fire Pipe Clamp Joint: When connecting, first thread the bottom of the connector, and then screw the tapping screw into the threaded bottom hole of the connected part. As the tapping screw thread surface has a high hardness (≥ 45HRC), can be connected to the threaded bottom hole in the internal thread, thus forming a connection.
