How to do a good job in the design of stone closing?

ONE. What is closing

Closing is the decorative treatment of the joints of the same material or different materials in decoration construction. It is the place that best reflects the beauty of details in decoration design. The reason why many classic cases are intriguing has a lot to do with the exquisite processing of closing details. A designer who doesn’t know how to close the mouth is like a doctor who doesn’t know how to bandage. Not only will the wound be exposed, but the corners will be damaged, and it will also affect the appearance.

TWO. The role of closure

The function of the closure: the decoration closure is to make up for the deficiencies of the decoration and increase the decorative effect through the process of treatment of the edges, corners, and connecting parts of the decorative surface. On the one hand, it refers to the splicing seam of the closing part of the facing and the treatment of the closing seam, covering it with facing materials to avoid the exposure of the base material and affecting the decoration effect; Decorate the transitional parts to enhance the effect of the decoration.

THREE. Closing method

Generally speaking, the methods of closing the decoration mainly include edge pressing, seam retention, butt joint, mortise joint, etc. These methods should be selected according to the design style, decoration grade, material properties, and component forms.

1. Edge closing method

The edge-pressing closing method is the most basic and common method for decoration closing. This method can be used for closing between different facing materials and between different structures. It is to use one of two adjacent materials or components to cover the other. On a material or member to achieve the purpose of closure. There are several ways to deal with edge closing:

a. finish that is easy to process or handle covers a finish that is difficult to process. Choose a cover finish that is easy to machine or handle on the construction site. Covering materials are processed to make the construction joints tighter and save labor. When the closing material is not suitable for processing and the closing seam is difficult to dense, it is necessary to use caulking glue to treat the closing seam. When the plastered wall and the steel door are closed, the steel door frame is used to press the plaster to close the joint, because the steel door frame is easier to form and more beautiful. If the plastered surface is used to cover the steel door frame, on the one hand, the plastered surface is difficult to form and the construction is difficult; on the other hand, the plastered layer is also difficult to attach to the steel veneer surface.

Therefore, pressing the plaster layer with a steel door frame is the best construction method. However, when closing the steel door frame and the stone wall, the texture of the two materials is relatively hard. If the closing joints of the two must be strictly consistent, the construction is time-consuming and labor-intensive, and it is extremely difficult; therefore, we use caulking Glue is used to deal with the closing seam, which can greatly reduce the difficulty of construction, and the same time, it can also make the facing have a certain degree of shrinkage.

b. Covers that do not shift may shift. In decoration construction, the decorative surface often needs to leave a certain expansion space due to deformation, so as to avoid the decorative surface from being squeezed or cracked. These parts are closed by the edge pressing method, leaving a certain expansion and contraction space for the lower layer of possible deformation of the veneer. It can avoid deformation of the closing seam.

c. Use special decorative components to cover the finish that needs to be closed, which is the most common way to close. For example, ceiling lines, decorative lines, air-conditioning outlets, etc., are closed with decorative components to cover the finishes that need to be closed, which simplifies the processing of the finishes at the close position, greatly reduces labor costs and improves work efficiency. When the decorative line is used to close the mouth, due to the small contact surface between the decorative line and the decorative surface, there are quality problems such as hollowing and falling off due to deformation and other reasons. Therefore, in addition to using adhesives for fixing, screws and nails should be used as much as possible for reinforcement. If you cannot use screws, nails, etc. for reinforcement due to the requirements of the finish, you should try to increase the contact area between the finish line and the finish. Or use dowels for fixing.

2. Seam closing method

The seam closing method is to leave a gap of a certain width between adjacent materials or components for closing. There are two cases of this closing method:

a.Close up the material with a hard texture. For hard materials, especially when they are large in size, it is difficult to keep the seams tight if they are closed with tight seams. Therefore, for materials with a hard texture and large specifications, such as stone and glass, the sealing method is usually closed with seams. When the size of the material is small, the use of seam closing can make the finish look neat and beautiful, but it will increase the labor of construction. If the material specification error is large, appropriate seams can be left to avoid a cumulative error. The size of the closing seam is determined according to the size of the material, and after the construction is completed, the joints are treated with cement paste, etc.

b. There is another kind of seam closure determined by the architect’s design style, which is mainly used to separate different components or separate different building parts. This kind of seam closing is actually a combination of various closing methods to make a certain width of a closing seam or dividing seam to achieve the purpose of closing. This opening is not only a closing construction process but also a design style.

3. Collision interface method

The collision method is widely used in the closure of wood veneer materials or stone walls. The method is usually to plane the colliding edges of wooden components into a bevel at a certain angle and then overlap each other. Wooden veneer bumps and sockets generally appear at overlapping positions such as large-area wood veneer and external corner wood veneer. It should be noted that because the joints are generally fixed with glue and other adhesives, the strength is not high; wood is prone to deformation with changes in temperature and humidity, and warping and hollowing deformation is prone to occur at the position of the joints. When warping and hollowing deformation occurs, glue can be injected into the hollowed part with a syringe, and then flattened and fixed firmly.

4. Mortise and tenon receiving method

The mortise and tenon method is generally used in the closure of thicker wood veneer or solid wood materials. It has a certain strength. It is not only a method of closure but also a method of wood construction connection. Generally, it is only used in parts with special requirements, such as the splicing of wood boards.

5. Decorative strip closing method

This is currently the most popular closing method, which is suitable for the widest range of scenarios, the most beautiful, and can meet various closing needs. Whether it is the ground, or the wall, or between the ground and the wall, or even the top surface and the wall material closing treatment, it can be used. a. The ground; b. The color of the edge trim on the wall is no longer single and even has a certain degree of decoration and functionality. c. Wall and floor When laying bathroom wall and floor tiles, we usually adopt the method of “wall pressing the floor”, because the gap is small, beautiful, and waterproof. The edge strip not only has these advantages but also instantly improves the sense of space quality.

The closed bricks of the inner corner and the outer corner are usually combined at a 45° angle when the inner corner and the outer corner are closed. This is not only easy to collapse and crack, but also has certain safety hazards. The rounded metal edge trim not only enhances the decorative effect but also eliminates these problems. Special-shaped edge closures use rubber and light metals to be soft and easy to shape so that this type of edge closure can perfectly adapt to various curved edge closures.
