What are the methods of edging and grinding?

The purpose of "collection" is to make up for the deficiency in decoration construction through various ways and means, so as to enhance the effect of decoration. Whether the decoration construction of a project is meticulous or not depends to a great extent on how to deal with the problem of edge closing. So what should I do to keep my mouth shut? Let's have a look. Common closing methods

First, blanking and necking methods

The hemming method is the most basic and commonly used method in decoration hemming. This method can be used for sealing between different decorative materials and different structures, that is, covering one of two adjacent materials or components on the other to achieve the purpose of sealing. There are several processing methods for edge pressing and necking:

1. Veneers that are easy to process or handle cover those that are difficult to process. Choose the decorative surface that is easy to process or handle on the construction site as the covering decorative surface. The covering material is treated to make the construction joints more compact and save labor. When the closing material is not suitable for processing and the closing seam is difficult to be dense, it is necessary to use caulking glue to treat the closing seam.

2. A cover that will not move may move. In the decoration construction, the decorative surface often needs to leave a certain expansion space due to deformation to avoid the decorative surface from bursting or cracking. These parts are closed by the blank holder method, leaving a certain expansion space for the facing that may be deformed at the lower level. Deformation of converging seams can be avoided.

3. Cover the facing that needs to be closed with special decorative components, which is the most common sealing method. Such as ceiling lines, decorative lines, air conditioning outlets, etc. Covered with decorative parts to cover the veneer to be closed, which simplifies the treatment of the veneer at the closed position, greatly reduces the labor cost and improves the work efficiency. When decorative thread is used for necking, there will be quality problems such as hollowing and falling off due to the small contact surface between decorative thread and facing and deformation. Therefore, in addition to the use of adhesive fixation, we should also try to use screws, nails and other reinforcement. Such as screws, nails, etc. Because the decorative surface can not be used for reinforcement, we should find ways to increase the contact area between decorative lines and decorative surfaces. Or fixed with a blind tenon.

Second, the joint sealing method

The seam sealing method is to leave a gap with a certain width between adjacent materials or components for sealing. This convergence method has two situations:

1. Hard materials are closed. Hard materials, especially when the volume is large, it is difficult to keep the joints tight if they are closed with dense seams. Therefore, materials with hard texture and large specifications, such as stone and glass, are usually sealed with seams. When the material specification is small, the use of caulking can make the facing look neat and beautiful, but it will increase the labor of construction. Whether to leave a seam is generally determined by the designer's design requirements and style. If the material specification error is large, the seam can be left appropriately to avoid error accumulation. The size of the convergent joint is determined according to the size of the material, and the joint shall be marked with cement slurry after the construction is completed.

2. There is also a kind of joint which is determined by the architect's design style. Mainly used to separate different components or separate different building parts. In fact, this kind of sewing is to use various sewing methods to make a certain width of sewing or parting to achieve the purpose of sewing. This necking is not only a necking construction technology, but also a design style.

Third, the method of touching the receiving port

Contact method is widely used in the closing of wood veneer materials, and its practice is usually to plan the contact edges of wood components into oblique angles at a certain angle and then overlap each other. The wood bark receiving port generally appears in the position where a large area of wood bark overlaps with the wood bark of the external corner. It should be noted that the joints are generally fixed with adhesives such as glue, so the strength is not high; However, wood is easy to deform with the change of temperature and humidity, and warping and hollowing deformation are easy to occur at the collision position. When warping and empty drum deformation occur, glue can be injected into the empty drum with a syringe, and then flattened and fixed firmly.

Fourth, tenon joint method

The tenon method is generally used for sealing thick veneer or solid wood materials, which has certain strength. It is not only a closing method, but also a wood structure connection method. Generally, it is only used in parts with special requirements, such as splicing boards.

How to choose the closing mode?

1, the style of decoration design is subject to the overall design style of the building, and the style of decoration design also determines the ending way of decoration. Therefore, the method of finishing decoration should be consistent with the overall style of the building. For example, modernist style buildings often have pure geometric modeling, clear and powerful lines, simple and bright colors, solemn and generous modeling, and no unnecessary fancy decoration. Leaving seams and closing them is the main choice. More tenons should be used for antique solid wood decoration.

2. The structure and function of decorative surface are also very important to the choice of sealing method. Different structures and functions of decorative surfaces have different requirements for sealing strength and beauty. In the frequently stressed parts, the requirements for closing strength are higher, and in the eye-catching parts, the requirements for the aesthetics and coordination of the facing are higher than those in the secondary parts. For example, the same solid wood veneer can be sealed by 45-degree joint or blank holder on the wall, while the wooden floor adopts tenon joint.

3. The difficulty of construction is also a factor that determines the ending method. On the premise of meeting the design requirements, the closure scheme with low construction difficulty and high efficiency is the best scheme. Generally speaking, the efficiency of blank holder closing is the highest, followed by leaving seam; It is difficult to reach the receiving port; Due to time-consuming and laborious, tenon joints are rarely used in decoration construction except for special requirements.

4. In actual design and construction, it should be applied flexibly according to the requirements of design effect and construction cost control. At the same closing position, different closing methods may achieve the same closing effect, and the same closing method may also produce different decorative effects due to different details. The choice of closure mode is generally determined by the designer's style and intention, the structure and function of the facing, the difficulty of construction and the nature of the material. These methods should be selected according to the design style, decoration grade, material nature and component form. Similarly, an overly complicated ending method will directly affect the cost of the project. As long as the design effect is achieved, the cost should be reduced by a simpler closure method.

At the same time, it needs to be pointed out again that the real necking should be the necking formed by the designer's inevitable transformation of decorative materials in order to meet the design effect. Therefore, in principle, how to choose the convergent scheme should be the responsibility of the designer.

Closed construction technology

Construction of wood closed line

A, the process scope of wood convergent line

1, convergence between different construction faces;

2, convergent between different decorative materials;

3, all kinds of lamps and equipment convergent;

4, furniture and decorative body convergent.

Second, the materials used in the necking process.

Besides wood thread, stainless steel thread, aluminum alloy thread and plastic thread are also acceptable.

Third, the preparation before surgery

1. Select the line and eliminate the twisted, scarred and decayed parts. The color and thickness of the lines are uniform, the metal lines are free from damage and scratches, and the size and shape meet the requirements.

2. Check whether the convergent base surface is firm.

Fourth, the technical points

1, the lines shall be fixed with glue as far as possible, and nails shall be added with a nail gun if necessary, and the position of the nails shall be on the back of the groove or sight.

2. When installing metal wires such as stainless steel and titanium plate, they should be lined with wood lining and fixed with all-purpose glue. After the construction is completed, the plastic film protective layer on the surface of the metal line should be torn off.

3. When cutting titanium wire, you can't use a grinding wheel cutter to prevent discoloration after heating.

4, wood line for arc convergent, if the arc radius is small, can be in the wood line inside saw a row of fine groove, groove depth is about two-fifths of the wood line, after the trial installation, add glue nail fixed, finally finishing to make it flat, smooth, smooth.

Five, different positions convergent process

1, ceiling wall and cylindrical convergent

There are several types of (1) interior angle convergence:

A. close the solid corner line;

B. diagonal closing;

C. eight-character ending;

D. gradually close down.

(2) There are three kinds of convergent angles: plane, vertical edge and convergent angle.

2, wood furniture convergent process:

(1) All intuitive doors should be sealed, drawers should be sealed, and doors should be sealed on all sides.

(2) Edge sealing materials: wood strips, plastic strips (tapes), metal strips and sawdust.

(3) Close the process

A. Solid wood sealing strips are generally fixed with nail glue;

B plastic sealing strips are usually fixed by caulking and gluing;

C, fixing the metal sealing strip with screws and glue;

D. veneer is fixed with all-purpose glue.

3, transition convergent (refers to the plane convergent two different materials butt convergent) can use wood line or metal line convergent, wood line fixed with nail glue, metal line must be done first wood lining, and then stick the metal line on the wood lining.
