The Status of Hardware Accessories in the Doors and Windows of the System-WJW Aluminum Supplier Aluminum Industry

1 What are the hardware accessories of the system doors and windows?

In the usual consciousness, doors and windows are just door and window accessories. Although there is also "hardware accessories is the heart of the system doors and windows", it has not actually paid attention to it.

The hardware of the doors and windows can be divided into the opening and closing part, bearing component, control components, and auxiliary components. Through the system matching and integration, it serves each subsystem of the doors and windows systems.

We also need systematic support and after -sales service. We cannot simply say that it is a hardware product, and we cannot give up individual hardware components, but talk about the concept of "doors and windows hardware systems".

To establish the concept of the system, formulate corresponding plans for various hardware products, and in the framework of large doors and windows systems, profiles, glass, tape, processing technology, and even the changes in door and window opening methods, the hardware of the doors and windows must be changed accordingly. Sales for doors and windows.

2. How does the load affect the choice of doors and windows hardware accessories?

Temperature effect parameters, variable load parameters, accident load parameters, permanent load parameters, wind load high change coefficient parameters, peak terrain correction coefficient parameters ("correction coefficient" items provided by industrial encyclopedia) have increased and adjusted. And many improvements and improvements have been made on the content and methods of wind computing. The basic snow pressure and basic wind pressure in some cities have been adjusted, and the new national basic snow and basic wind pressure diagrams are drawn. This provides a more detailed theoretical basis for our calculations.

3. The impact of the environment on the wind pressure of doors and windows?

In different regions and different environments, the wind pressure requirements of the system doors and windows are different. According to the comprehensive calculation of various parameters, the location and quantity of the lock point should be determined to ensure the required performance requirements. Generally speaking, the more locking the point, the stronger the wind resistance of the doors and windows.

At the same time, we must also consider the configuration of the lock point. Only in the case of reasonable selection of the number and layout of the lock point can the multi -point lock play the most effective role. Under the premise of ensuring door and window performance, optimize doors and windows layout, reduce hardware use costs, and determine the best configuration solution.

4. How to calculate the lock formula?

The calculation of the locking point is more complicated. Here is a simplified formula for calculating the lock points:

N-locks; w-fan width; H-fan height; WK-standard wind pressure; safety factor-2.5 times, then nW H 2.5 WK/0.8 ()

After determining the number of locking points, you must choose the appropriate hardware category according to the cross -section shape of the system doors and windows. Different hardware categories, the shape of the lock point, and the usage are different. Usually, the open window is turned off or sliding support as the lock point.

5. How to choose the hardware of aluminum alloy doors and windows?

(1) First of all, consider the wind pressure, gas tightness and stability of the doors and windows:

(2) Select hardware manufacturers with quality assurance and reasonable hardware attachments from the size, vertical and horizontal ratio of the doors and windows and window frames, the shape of the profile cross -section, and the opening of the window;

6. What is the system?

He said: "This system is composed of some interoperability and affected things. It can also be said that the system is a whole composed of the relevant part. For comprehensive analysis of the constituent unit and the final composition, it is not a system's point of view. It is not a system's point of view, refers to a unit, or only pays attention to the macro as a whole. The system is an organic whole composed of different elements. The system and the system elements are relative. It can be a system, and there is a overall and part -time relationship between them.

7. To make a set of doors and windows, first determine the contour of the doors and windows, or is it a first -order hardware accessories?

When considering the hardware selection of the door and window system, the door and window system must be comprehensive research and understanding, especially the design and selection of the doors and windows systems.

It can be said that there is no good contour as the cornerstone, and what hardware cannot be done in the end, and should be considered and selected comprehensive on the outline and hardware. Do not pay attention to the choice of contour before choosing the hardware. The outline cannot find the matching hardware.

Most real estate developers now consider the combination of configuration and hardware, and then weigh them. The choice of accessories should be taken into account the universality and reasonableness of accessories, as well as the technology and material quality of accessories production.

8. How to adjust the closure of doors and windows?

step 1:

The closing part of the door can only be installed on the side of the upper part of the door fan near the side of the hinge. There is a speed adjustment screw on the valve body, facing the hinge, otherwise the door guard cannot open normally. Destruction, the body will be fixed on the door with four screws, and then inserting the lever into the upper end of the gear shaft. The other end will be installed with a lid and a fastener screw.

Step 2:

Install the connecting rod and fix the connecting rod on the door frame with two screws. Handheld connecting rods and door frames are right angles. Remove the lock -tight nut, adjust the connecting rod to match the length, gently move the leverage, so that the lever sales are inserted into the holes at the end of the connector, and check whether the link rod is in a right angle with the door frame. Put it on the cushion and fix it with a semicircular screw. Lock the nut and install it.

9. The structure and principle of embedded doors closed.

(1) Structure: The embedded door top spring consists of a hydraulic buffer spring installed on the door fan, a slider and connecting rod installed on the door frame. Because the embedded door closure device is installed in the slot of the door fan and the door frame, the appearance of the door when the door is closed is not affected, and it is suitable for the door of high -end hotel rooms.

(2) Principles: The hydraulic buffer spring gives a recovery torque to the connecting rod, so that the connecting rod is rotated in the direction of away from the hinge, which drives the slider to keep the slider away from the hinge at the same time, thereby achieving the purpose of closing the door. There is a temporary lock card in the front of the slide. When the door is opened to the right corner, the slider moves to the side of the hinge, locks the card in the tongue groove in the front of the slider, so that the door is temporarily locked in this position.
