Open the lower hanging window inside.
In order to make the users of the collection easy to refer to, the compiler conducted a number of social surveys, and learned the structure and design standards of plastic profiles and stone fittings, and selected the gold parts of many door and window assembly factories in Shanghai. The assembly process was analyzed, but 6 series of window type opening methods were used to select components and other systems, and a lot of manpower and material resources were invested. For example, the casement window hinge has a flat hinged sliding hinge hinge opening screen hinge; the locking method has a linkage handle actuator, etc.; the sliding window locking method is divided into a lock buckle actuator; the gold piece of the inner hanging lower hanging window is more complicated. There are handle transmission lever steering angle locking block guide rod steering support, etc., used in detail, even flat, window sash lift slider and sliding window limit block and other small places are considered. There are also detailed nodes for the assembly of earthen parts for various doors.
In order to guide the juicers to select the gold parts reasonably, the compiler has put forward clear technical requirements for the materials used for the quality of the finished products. The assembly of the gold parts is also clearly defined. The gold fittings of the force must be lined with a metal galvanized lining of 5=2.5 mm thick in the inner cavity of the plastic profile. The process of lining the metal plate must be carried out before the welding assembly; the gold fittings are faced with the positioning dimensions of the main gold fittings. In the technical requirements, the applicable rules of the frame fan rule 10 and the gold fittings involved in the node are specified, which helps the door and window juice workers to make a reasonable choice for the window design gold fitting specifications from the perspective of the applicable safety parts of the gold fittings. This is of great benefit to the majority of door and window assembly companies, especially new ones.
For those who are involved in the design of the window, the 4 redundant plastic window sill fitting assembly node is a very good teaching material. It is a plastic window sill, and the armored seal greets Shanghai Kaijie Door & Window Co., Ltd. Gu Jixin 1 Plastic The basic requirements of the sealing treatment in the installation of the window frame are the same as the physical properties of the building of the door and window. The sealing treatment of the frame installation should consider the airtight watertight insulation and sound insulation of the door and window installation. These performance indicators should not be lower than the design specifications of the door and window products themselves. Due to the influence of the materials used for the sealing treatment and the conditions of the sizing, it is difficult for the sealing zone to reach and maintain the performance index of the above-mentioned children for a relatively long period of time. Therefore, it is necessary to have an effective shelf life for the sealing process.
2 structural design of the sealing area of ​​the sealing area, first of all, it should be considered that the outer frame opening can usually be divided into lap joints.
The lap joint and the groove joint have a long sealing width, especially between the lower frame and the hole opening, and the water shovel is added, so that the sealing effect is good, but the way of lap jointing, the upper frame and the opening of the hole should be noted. The sealing area is easily washed by the flowing water on the upper wall, and the expensive water flow must be blocked by the watertightness of the wooden body of the mountain door and window. Therefore, it is only suitable for buildings with awnings or deep concealing; The complexity of the structure has increased the workload of the seven constructions and is therefore not very common. The way of splicing is the most common, so the form of gap processing is studied and more representative.
The gap structure of the flat connection mode can be divided into a segment structure of a sealing tape with a heat insulating filling tape sealing band from the outside to the inside. The popular mode today is the use of broken glue for filling the inner and outer sealing foaming agent. Whether this is the best sealing treatment is worth pondering.
First of all, the silicone series sealant, even if it is neutral, does not have a maximum of 15. The expansion and contraction of several cold and heat changes, and the joints are cracked and develop rapidly. In particular, after the outside water enters the water, it may cause the outer seal to be completely destroyed by freezing and extinguishing the gas.
Secondly, the foaming agent is a kind of sealing material, and with! . It has good compatibility, but in the door and window engineering, it is difficult to achieve the sealing effect. This is because the profile is difficult to achieve in the construction of the seal. 0, the foaming agent should be fully effective under conditions such as suitable temperature and wet surface; 1.1; the foaming agent must also be fully foamed and filled into every corner of the filling area to have flexibility. Convenience and containment. These conditions can be realized in a local environment, and the nodes are rich and detailed. In each series, there is an intuitive node index, which makes it easy to find the node code and the page where it is located. number. This set is very useful for the position of assembly and assembly engineering and production management, so that the assembly quality of the gold fittings can be controlled during the component processing stage, for example, before the welding, the preset liner is milled. Assembly process holes, etc., interlocking to improve the quality of plastic doors and windows. Therefore, it is recommended that the relevant departments use this set as a training material for plastic door and window practitioners.
In recent years, plastic doors and windows have developed rapidly, and new profile gold fittings have been continuously introduced. The concentrated selection of European-style profiles, but the 77 series of sliding doors and windows widely used in the market is not selected, can not be considered a regret. In addition, the actual use of the Shanghai market is small, but the door and window design set has passed the identification of American plastic doors and windows, and its gold fittings assembly node still has no standard for reference.
Some of the new high-end nine-enterprise accessories, such as the flat-open window window regulator and the Gonggong hinged window, are also the door and window designers want to master. It is hoped that compilers will be able to compile this sequel at the appropriate time to meet the needs of the plastic door and window industry. Wang Weitai feed
