Is there a predecessor in curtain wall?

Columns and beams and other visible rods should be hung up and sprayed or put into the oxidation pool when the surface treatment is carried out in the profile factory, and a small hole needs to be punched at both ends of the profile in order to hook it, and in the blanking process, in order to avoid this small hole being seen after the installation is completed, part of the profile at the end will be cut off when cutting the material, which is the reason for subtracting 50mm. As for the ferrule plate pressure plate you said to reduce 100mm, this is because the processing length of these parts is relatively small, some are about ten centimeters in length, in the process of processing, if you use a single-head saw or double-head saw large machinery to cut, the processed base metal in the final shorter time is not able to cut the machine, that is to say, the last 100mm 150mm machinery can not continue to cut processing, it is useless.

There are profile blanking requirements for exterior finishing, the south is generally reduced by 50mm, and the north is reduced by 100mm, which is related to the process of the profile factory, the main reason is that there are hoisting holes at both ends of the profile when spraying, so this size should be reduced. The ferrule, the supporting plate and the pressure plate can be reduced without a ruler, because it is invisible from the outside and there is no finishing requirement, but in general, it is also reduced by 50mm; Unless there is oblique blanking, the material gap should be left 25mm instead of 5mm. Hope it helps!

The curtain wall also contains a lot of materials, such as: aluminum profile, to determine the length, cross-section, glass panel, to determine the length and width of the size, aluminum veneer, stone size processing drawing, etc., there are many materials are to be out of the corresponding processing drawing, statistical quantity, these must be ordered in advance to ensure the construction progress.

According to the square meter area of the money, fine blanking: out of the bill of lading, out of the processing drawing, out of the blanking details of 20 yuan per square meter.

Ordinary blanking: out of the bill of lading, out of the length of the blanking details of 5 yuan per square meter.

Seeing if your relationship is good or not, I will do it for others for three yuan.

The installation of 12mm glass on the curtain wall is generally about 150 **, and other materials are counted separately.

Negotiate a mutually acceptable **.

Hello, I produce aluminum alloy doors and windows, curtain wall profiles, with our materials can assist in remembering the support, blanking.

If you want to cut the material, find the ultimate cutting software, trustworthy software! The trust of more than 3,000 domestic manufacturers!

We used to use encyclopedia to calculate, and the results were similar to the software developed by the company itself, basically the same!

Find a cable to optimize that.

There is a special curtain wall automatic blanking program, and the following is a demonstration of this program:

It seems a bit complicated, can you make it simpler, for example?

It seems that there is not, because there are too many manufacturers of profiles, and the varieties are varied, and the size of the material may be different if the hardware accessories are not the same, so as long as you master the calculation method (such as the amount of lap joints, etc.).

There is a software called Jin Changfeng, which can be used to calculate the cutting optimization scheme of materials, but it is also very complicated with many specifications, and it is very expensive.

The hand-held one adds 4 mm, but it is not strict, mainly the manual one is always less than 3 mm by eye, and the automatic 2, 3, and 4 position welding will be standard 6 mm. Set the window hole size is 1000 1000, then the blanking size is 1000-40 + 6 (4) = 966 (964), where 40 is the reserved window hole stucco layer. As for the size of the inner sash, the size of the swing door and window, the size of the corner balcony, the size of the splicing window, etc.

The cutting formula of aluminum alloy doors and windows varies according to the manufacturer, the profiles used, and the large samples of doors and windows. Take the sliding window as an example: the calculation of the cutting size is based on the method of first the outer frame and then the inner fan, such as (up) sliding length = total width - frame (thickness) x 2 + lap size with the frame.

If you have no experience, you can measure the hollow and determine the length of the light hook, the length of the upper and lower parts (two openings) = (the length of the slide + the thickness of 1 light enterprise) 2 - the size of the tenon. Before processing aluminum alloy doors and windows, it is necessary to figure out the structure of doors and windows and the function of the profiles used.
