1. Doors: There are mainly two kinds of sliding doors and doors. (The so-called flat open, is hinged on the axis, rotating open). Open the door is divided into two kinds of internal and external doors.
2. Windows: In addition to sliding windows (including left and right sliding windows, up and down sliding windows) and flat windows (including inside and outside windows), there is a window that is suspended upwards. Different opening methods have different characteristics:
(1) Sliding window: The advantage is simple, beautiful, large window, large glass, open field of vision, high lighting rate, easy to clean glass, flexible to use, safe and reliable, long service life, open in a plane, take up less space , Easy to install screens, etc. At present, the most used is the sliding window. The disadvantage is that the two windows cannot be opened at the same time. At most, they can only be opened halfway. The ventilation is relatively poor; sometimes the sealing performance is also slightly poor.
(2) Casement window: The advantage is that the open area is large, ventilation is good, sealing is good, sound insulation, heat preservation, and impermeability are excellent. The open type wipe window is convenient; the open type open space does not occupy space. The disadvantage is that the window width is small and the field of vision is not open. Open the window to open to occupy a piece of space outside the wall, easy to damage when the wind blows; and open the window is to take up some of the interior space, the use of screens is not convenient, the use of screens, curtains, etc. is not convenient when you open the window , If the quality does not pass, it may also seep rain.
(3) Suspension type: This is an aluminum alloy, plastic steel window that appeared later. It is a new form developed on the basis of a casement window. There are two ways to open it, it can be open, but it can not be pushed open. When the casement window is closed, pushing out the upper part of the window can open a gap of about ten centimeters. That is, the window can be opened a little from above. The open part is suspended in the air and fixed to the window frame through hinges, etc. Suspension type. Its advantages are that it can be ventilated and it can be kept safe. Because of the hinges, the window can only open ten centimeters of seams, and it can't come in from the outside. It is especially suitable for use when nobody is in the house. Recently, this function has not only been limited to a flat open window, but also a sash window can be opened upright.
Pipeline renovation is a project that was otherwise encountered in home decoration. Gas pipelines must be approved by the gas management department for approval of construction. The main components of the gas pipelines are the water supply and drainage pipes and heating pipes.
When the water supply pipeline is reformed. Should be based on design requirements, pre-excavation through the pipe hole, pipe threading, pipe bracket embedded. When installing the water supply pipeline, it should be pre-installed, and after the inspection is correct, it should be connected and installed. The connection of the pipeline is generally a threaded connection method. Screw the pipe end with a pipe fitting with internal thread, and then connect it with other pipe sections. The specific method is: firstly twist the pipe joint at the thread direction with a slight twist, and then evenly apply white. After the lead oil or directly wound with tape, press the joint into the joint, screw it into 1/2 joint long, and then use the same method to process the interface in the second section of the pipeline, and screw it into the joint for another 1/2 of the length and screw it out. White lead oil and hemp must be cleaned in time. Heating pipe construction above.
The construction specifications for the pipeline renovation project are:
1. Through hole in the wall: According to the design requirements of the pipeline renovation, mark the center position of the hole through the wall on the wall, mark it on the wall with a reticle, and use the impact drill to punch the hole. The center line of the hole should be worn The center line of the wall pipe coincides and the hole should be straight.
2. Pipe threading: This is the key to guarantee the installation quality. To use a threading plate to thread the threaded thread on the inner wall of the nozzle, the force is required to be even when the thread is laid, and no twill or tangled thread can occur. The nozzle is tested as a tapered thread.
3. Connection: The tube should be cleaned before installation. The wall is clean and free of debris during the period. When installing, it is necessary to find out the position and direction of each water pipe joint to ensure that the water equipment is properly connected after installation. When the hot and cold water pipes are installed parallel to each other, the hot water pipes should be above the cold water pipes. When the waterway pipeline is reformed, the main valve for indoor water supply shall be closed, and no water shall be allowed to carry water. After the renovation, check the water to see if the interface is closed and there is no blockage. After the installation of the pipeline is completed, the pipeline shall be cleaned, painted with anticorrosive paint, and painted with silver paint.
What are the types of aluminum alloy doors and windows, plastic steel doors and windows?
Although the aluminum alloy doors and windows and plastic steel doors and windows are different in material, they are similar in structure and use. The types of aluminum alloy and steel doors and windows are mainly divided according to the opening method. There are mainly the following:
