How do you connect two profiles together? What is the Advantages and the Disability of any Method
Here is a small and useful summary of all available technologies. We will refer to a number of standard and recognized methods: rig, screw and speech, anchor opens, nail steel, self-drilling screw.
Compare the methods: Check costs and times (experienced case)
To better understand the differences, let’s take an example of a link between a 4-mm-in-the-art profile with a 6 mm- thickness profile. We want a connection that has over 12 tons of fun.
| The method of connection | A time of work is approximate | approximate cost | Best and general rankings |
|---|---|---|---|
| and shook | 15-20 minutes of professional work (for 30 percent of the total length) | About 80 NIS (Fall raw materials for filling + library against corrosion) | ✓ Standard selection. |
| screw and speech | Almost half an hour to drill (with a magnetic drill bit when the holes are not ready) and the drawer in the Mandatory is required. | About 40 NIS (less professional + cost of the screws) | ✓ conservative alternative |
| anchor opens (STRUTBOLT) | About an hour (Send 4 holes in diameter 20 mm and install 4 anchors M12/18) | About 150 NIS (including the anchors, a very high cost) | ✗ Dear and slow (but uninformed) |
| A shot gun (a gun). | The fastest in terms of time. | About 50 NIS (about 25 shots of 2 NIS per ⁇ ) is conditioned in a tyrant gun with 7000 NIS | ✓ Very fast. |
| The self-drilling screws are clogged | A few minutes. | Only 2.5 NIS (about 10 screws with approximately 0.2 NIS per one) | ★Not a filter is valued because of the connection between the snoring screws and cheap products and the most effective and cheapest solution. |
Details of the available methods and technologies
1. 1. The method of fusion
This method is a physical action based on the contracting of one of the metallic bodies, usually adding additional metal as a filling material. The method is very classic, with the option of being the same as the suffering of the associated steel profiles.
Disadvantages of the method:
- In connection with two different materials or materials in different thickness: the fusion device and filling in accordance with the materials and thickness. It requires the worker to be very professional.
- There are materials that cannot be ripped off.
- Your service area loses its protection to the corrosion and requires complementary care (even if it is a nirosata).
- Visual control is partial. Testing the nature of the connection requires complex and expensive tests such as magnetic, ultra- Sony, radiography or with penetrating fluids.
- The final is not always aesthetic and will require a cleaning and snoring of the fusion snoring before making a color correction.
2. Method of screw and Coum
She is particularly good when the holes are ready. If there are no holes prepared in advance, use the magnetic drill bit to drill them on the site. The method is easy to implement and cover.
Disadvantages of the method:
- Requires access to both sides of the connection. And also a certain thickness for the head of the screw and the speech.
- A thick profile takes a long time.
- Finish with a prominent head of screw/A speech.
3. The anchor system was opened behind the profile (STRUTBOLT)
anchor female female who was opened by the closing of a male burger or a cone whose sleeve is open to the sages that oppose the anchor virus. When the holes are ready, the installation is very fast and easy, even when there is no access from the other side of the connection. The suffering is well defined and supervised for the execution is very easy, the possibility of heavy connection with a large thickness.
Disadvantages of the method:
- A thick profile takes a long time.
- The anchor cost is very high.
- Finished with a prominent head of screw.
4. The method of shooting
This is a method of connecting two profiles by special nailes that are shot with a slash gun or gas. The installation is very fast and easy and the suffering of the connection is well defined.
Disadvantages of the method:
- It requires buying a gas gun or high-cost sage, even the non-expensive or non-expensive masses, and not all types of applications, for each other thickness suitable for another nail and/or other gun.
- Absorient profiles require heavy and not easy devices to use and install in thin profiles, there is difficulty not to bend or hit because of the shot force.
5. The steel system is called Iscarriage.
This method is based on the self-drilling screws that produce the exclusion within the profiles, with or without pre-injury. The installation is very easy and does not require special equipment (except a fairly fast, standard screw) and enables quite accurate design of the connection will suffer, without the need for supervision.
Disadvantages of the method:
- Most of the steel Barghi in the land of imported from China and are of very low quality, without any written suffering. From there, the infidelity of planners in steel.
- Pre-cution is required with a total thickness of over 12 (up to 15 m) between two profiles.
- The barbaric diameter is limited (up to 6.3 m) and this means that their endurance is also limited (about 1300 kg per screw).
The bottom line in the test result
It is hard to understand how such a simple, easy, easy-to-control and cheap method can be found at the table of the designer’s options. (See the coded steel) method.
