Flat door


A side hung door is a door whose hinges are attached to the side of the door and open inward (left inside, right inside) or outward (left outside, right outside). It consists of door cover, hinge, door fan, lock and so on.


Single door opening and double door opening are terms in another classification system, and peace door opening is not contradictory.
Flat doors have single and double open flat doors.
A single door door is a single door panel with one side serving as a door shaft and the other side can be switched on and off, while a double door door has two panels, each with its own door shaft, opening in both directions.

The flat door is divided into one-way opening and two-way opening.
One-way opening means that the door can only be opened in one direction (only push in or pull out). Two-way opening means that the door can be opened in two directions (such as a spring door).
The flat door is relative to other opening ways to divide, because the door has mobile opening, upturning, rolling curtain lifting, vertical lifting, rotary and so on.
The market often refers to the aluminum alloy sanitary flat door as flat door.

Distinction of characteristics

Aluminum door profiles and glass styles are divided into north and south. In the north, thick aluminum and steady style are the main characteristics. The most representative is the lattice style, and the most characteristic of the lattice is Tange. In the south, various aluminum shapes and styles are the main characteristics. The most representative is the flower glass style. The more distinctive styles are lattice, ice carving, shallow carving, crystal shell and so on.

Flat door classification

Material classification
It can be divided into: solid wood doors, composite solid wood doors, molded doors, etc.
Solid wood door: thick texture, good sound insulation effect, giving people a warm and soft feeling, but easy to deformation.
Composite solid wood door: generally made of fir as the core, affixed with high-density board, and then coated with a layer of solid wood on the surface, strong and not easy to deformation.
Molded door: It is made of wooden fiber after high pressure machine, and the surface is easy to make a variety of concave and convex modeling.
Formal classification
It can be divided into: ordinary flat door, door in door, child and mother door and compound door.
Ordinary flat door: that is, a closed door opened by a single door.
The door in the door: it has the advantages of both the fence door and the flat door. The part of the outer door is the fence door, and there is a small door behind the fence door. Opening the small door can be used for the ventilation of the fence door, and closing the small door can be used as the flat door.
Child and mother door: generally used for the family door frame larger residential, that is, to ensure the convenience of access at ordinary times, but also to allow large furniture convenient to move in.
Compound door: also known as one frame two doors, the front door is a fence door, the back door is a closed flat door.

Hardware selection

Different ways of opening and closing doors used different hardware, common door hardware, sliding door hardware, folding door hardware and so on. Flat door is the most common form of opening and closing, widely used in a variety of different places. Because of the hinge side hardware form is much the same, so the key from the door locking aspect to discuss the choice of hardware with flat door.
A common form of door lock
Common locking devices include single-point door lock, multi-point door lock, door driver with safety lock hook, etc. In comparison, they each have their own advantages and disadvantages [1] :
1, single point door lock
The characteristics of single point door lock are: hand drive oblique tongue, key drive square tongue; In normal conditions only the oblique tongue acts as a lock. The square tongue can be stretched out by turning the key to play the role of security and anti-theft. The advantage of single point door lock is simple structure, easy to use; Disadvantages are also obvious, because it is a single point locking, resulting in poor sealing performance, but also can not prevent the door deformation.
2, multi-lock point door lock device
The common multi-lock point door lock device can be divided into two types according to its structure: linkage door lock and door driver.
The lock body part of the linkage door lock is similar to the single point door lock. It is equipped with a sliding rod at both ends of the lock body, and the sliding rod is connected with a connecting rod with a locking point. The door buckle and lock seat are installed on the frame, so as to achieve the effect of multi-point locking.
The door driver can be divided into two kinds: simple door driver and lock door driver. Simple door driver is used for indoor doors without anti-theft requirements, and can also be used for single-side anti-theft occasions, that is, only the handle is installed on one side. With lock door driver, a lock box equipped with a lock core is added on the basis of simple door driver. The end of the slide rod of the transmission is made into a rack form, and the corresponding steering Angle and connecting rod are matched to further increase the number of locking points and enhance its sealing performance; If it is used with the inclined tie rod, it can also realize the function of flat open suspension. Compared with the single point door lock, the advantages of the multi-lock point door lock device are very obvious: the multi-point lock has good sealing performance, but also can make the force of the door frame and the door fan more uniform, so as to effectively prevent the deformation of the door fan.
3. Door lock with locking hook
Door lock with locking hook is on the basis of multi-lock point door lock device, one or more lock points into the form of locking hook, so on the basis of multi-point locking, and greatly enhance the anti-theft performance.
Door lock selection
Different places have different requirements for the performance of the door, the appropriate door lock should be selected according to the actual situation. The state vigorously advocates energy conservation in buildings. The Fifth Plenary Session of the 16th Central Committee of the CPC adopted the proposal for the formulation of the 11th Five-Year Plan, with the top goal being to reduce energy consumption. Relevant departments are pushing to incorporate the system of energy conservation standards into national policies to improve the efficiency of the implementation of building energy conservation standards and implement the spirit of the 11th Five-Year Plan to develop energy efficient buildings.
Generally, the opening and closing frequency of indoor doors is higher, and the sealing performance is not high. Single point door lock with convenient operation can be selected.
Doors connected with the outside world (such as balcony doors, hotel or office corridor doors, etc.) should be selected as far as possible with good sealing performance of the multi-lock point door lock device, in order to improve the energy-saving effect of the building.
Some of the security requirements of the relatively high occasions can be used with a lock hook door lock.
