In the wooden keel, what is the main keel and what is the secondary keel?

The main keel is a longitudinal member of the bow and stern posts at the base of the hull** in relation to the side keels on both sides of the keel. It mainly bears the longitudinal bending moment of the hull, and when making a ship model, it is necessary to choose rectangular cross-section pine strips with straight wood grain and no knots. Secondary keel uses:

Hanging gypsum board, can also be used as a cross-brace keel.

The keel is the most important load-bearing structure in a boat, motorboat or boat. It is located at the bottom of the ship. On the top of the keel there was a cross-rib reinforcement.

In the bow and stern, the keel went around the bow post. The keel is usually the first part of the hull to be built. The laying of the keel is the most important event in the shipbuilding process.

Main keel: The main keel refers to the keel that is mainly load-bearing on the load-bearing ceiling. The main function of the main keel is to bear the main gravity of the ceiling and provide a stress surface for the erection of the auxiliary keel.

Auxiliary keel: Auxiliary keel refers to the keel that distributes the load on the load-bearing of the ceiling. The main function of the auxiliary keel is to disperse the load-bearing surface of the ceiling and provide the stressed surface for the laying of gypsum board.

Regardless of the horizontal and vertical direction, as long as the whole root is the main keel, and the cut is secondary.

In the ceiling keel, the main keel is C-shaped, the auxiliary keel is U-shaped, the thickness of the main keel is lower than the foot of the auxiliary keel, and the side height is lower than that of the auxiliary keel.

There are three kinds of keels in the decoration ceiling:

Edge keel: a kind of ceiling keel used for fixing and horizontal positioning around the ceiling and making manholes.

Main keel: The keel in the ceiling that carries the weight of the ceiling.

Auxiliary keel: used to hang gypsum board, can also be called cross brace keel.

Most of the light steel keel is used in the ceiling, the light steel keel, the surface is treated with hot zinc, and it is not rusty and deformed for a long time.

First, the role of the keel

Keel is a material used to support modeling and fix structures, and is the skeleton and substrate of home decoration, which is very commonly used.

Second, the classification of keels

There are many types of keels, according to the different materials of production, can be divided into wooden keel (there are many models, used to support the outside decorative board, play the role of a bracket), light steel keel (light steel keel is a very popular decoration material in the past few years, it can be used for ceilings, partition walls, strong fire performance, with light steel keel can make a variety of beautiful shapes), aluminum alloy keel, steel keel, etc.

Wooden keel 1 wooden keel 2

Light steel keel 1 light steel keel 2

Light steel keel 3 is divided according to the use part, and can be divided into ceiling keel, vertical wall keel, paving keel and hanging keel etc.

According to the different decoration construction technology, there are load-bearing and non-load-bearing keels (i.e., the keel of the master and the keel of the non-man).

Coupled with the different specifications and shapes of each keel, the types of keels can be described as very different and dazzling. As far as the light steel keel is concerned, according to its model, specification and use, there are T-row, C-shaped, U-shaped keel, etc.

There are several kinds of keels, the general decoration is more light steel keel and wooden keel (also called wood square is generally used more than 300 * 300mm) is the ceiling used to do the base, light steel keel is used for the kitchen bathroom aluminum buckle ceiling is more (**generally between 15-20 is better), wooden keel is used to make modeling ceiling (** is generally about 30 according to the bundle).

Keel is a construction term, and the keel in a building is actually a building material used to support the shape and fix the structure.

The main role of the keel in the building is to play a structural support role in the structure where it is located, maintain the original shape, and play a very important role in meeting the stability of the slag core required by the building materials. Because it plays a supporting role, you should try to choose a stronger material. There is no way to save on the budget in this regard.

Types of keels:

1. Wooden keel: Wooden keel is actually a material that is more commonly used in the decoration process, with multiple models, mainly used in a decorative board that can support the outside, so as to play the role of a support. Wooden keels are widely used in the production of suspended ceilings, partition walls, and solid wood floor skeletons, and are mainly made of pine, basswood, fir and other woods.

2. Light steel keel: The so-called light steel keel is a kind of construction metal skeleton made of relatively high-quality continuous hot-dip galvanized strip as its raw material and then rolled by cold bending process.

3. Aluminum alloy keel: Aluminum alloy keel is an improvement on the iron paint keel. Because aluminum will not rust and decolorize after oxidation treatment, the original iron sheet paint keel will cause rust, yellowing and paint loss due to oxidation for a long time.

4. Ceiling keel: Ceiling is a keel building material used for ceiling modeling.

5. Vertical wall keel: The façade of the vertical wall keel is the keel next to the wall, which is the keel of the vertical digging wall.

6. Paving keel: The so-called paving keel is also a keel fixed on the ground.

7. Suspension keel: The hanging keel is actually a keel material used to connect objects.

1. [Keel]: It is a longitudinal member connecting the bow column and the stern column at the base of the hull, which is located at the bottom of the ship. On the top of the keel there was a cross-rib reinforcement.

In the bow and stern, the keel went around the bow post. The keel is usually the first part of the hull to be built.

2. [Keel Structure]: The keel structure of ancient Chinese ships is a major improvement in the shipbuilding industry, which has a profound impact on the development of ship structures in the world.

At the bow and stern of the ship, the dragon potato slaps its bones around the bow post. The keel is usually the first part of the hull to be built.
