Use a furniture coupler only in production. Traditional fasteners are not advised to use in this case. A special screed is characterized by special properties that allow you to hide fasteners and greatly facilitate the assembly of furniture in general.
In production, several types of furniture ties are used. Consider their features and application.
Eccentric screed
This type of fastening is used in the factory manufacture of furniture, because it involves a rather complicated process of drilling holes. Furniture eccentric screed consists of an eccentric and a stud. Each of these parts is inserted into different parts.
The main advantage of this fastener method is its stealth. It does not spoil the appearance of the furniture. In addition, this method of fastening allows you to repeatedly assemble and disassemble furniture. This information is relevant for people who are accustomed to frequent travel.
The eccentric furniture screed allows you to connect various parts from any angle.
Mounting Features
It is quite difficult to use this method independently in the manufacture of furniture. The holes are not only difficult to drill, but it is also impossible to carry out joint corrections during assembly of parts. The main difficulty in drilling is the manufacture of holes for an eccentric. This is a through hole that requires the use of a Forstner drill. For a standard eccentric, a drill with a diameter of 1.5 cm must be used.
To make a hole for an eccentric, it is necessary to correctly markup on the part. After the drill Forstner make holes for the eccentric. At the end of the part under the rod, make a hole with a drill with a diameter of 8 mm. The parts are interconnected and fixed by turning the eccentric 180 degrees clockwise.
The depth of the sample should be about 12 mm. And the thickness of the chipboard panel is 16 mm. Only 4 mm of non-drilled wall thickness remains. The difficulty in installing the furniture screed yourself is the risk of drilling through the part. To do this, when drilling holes for an eccentric, drill with depth limitation is used.
Confirmate
Confirmation furniture screed is the most common type. Popularity is due to ease of use. Compared with other types, with confirm, it is much easier and faster to assemble furniture. Especially if you have to independently prepare holes for fasteners. This fastener allows you to interconnect two parts at an angle of 90 degrees.
To reliably connect parts to each other, they need to drill 2 holes. In one part, the hole should be equal to the diameter of the confirm head. At the end of the second part, a second hole is made with a diameter corresponding to the thread of the part.
Often, for this procedure, it is necessary to use drills of 5 and 6 mm. In order not to replace accessories, you can purchase a combination drill in stores that allows you to drill various holes at the same time.
Confirmate is a universal type of furniture screed, which has its own application features and disadvantages.
Be sure to confirm with the dowel. This is a special wooden rod. Its length is up to 30 mm, and its diameter is 6 mm. The dowel acts as a guide, which does not allow the parts to move during tightening. This method of connection allows you to achieve high accuracy when connecting.
This method of screed allows you to disassemble and assemble the furniture several times. But remember that the material of the chipboard does not tolerate such manipulations. Often, after the first disassembly, the furniture screed does not hold parts well.
Confirmation must be carefully wrapped. It is better to perform this procedure manually or set the minimum speed on the screwdriver. Otherwise, the thread of the fastener will act as a drill, which will finally break the already prepared hole.
To "drown" the hat in the body of the part, use the key. Follow the steps carefully, slowly, because the thread may break. In some cases, additional galvanizing is necessary. Confirmate is a fastener that remains visible after use. Therefore, you must first purchase special stickers or caps that will securely hide the fastener cap.
Intersection Screed
This fastener consists of a nut and screw, which are able to pull together 2 sections of furniture. Often they are used in cabinets. In this case, up to 4 intersectional furniture screeds are used. Install them near the corners of the parts to be joined. Often furniture is made from chipboard. Depending on the thickness of the material, various sizes of fasteners are used.
For the manufacture of cabinets from a standard sheet of chipboard with a thickness of 26 mm, an intersectional furniture screed of 32 mm in size is used. If the cabinet is made of a thicker material, fasteners up to 50 mm are used.
Special types of screeds
Unique fasteners are often used to create exclusive furniture. Widespread among special types of screeds received fasteners for countertops. Its main purpose is to connect two halves of the dining table planes.
Two C-shaped and a hairpin are placed in the lower plane of the countertop. For this, a cylindrical recess is drilled in it. It is also necessary to mill the groove. At least 2 screeds will be needed on one table.
Furniture corners
This fastener does not guarantee a secure connection. Therefore, it is used for fastening parts on which a minimum load is assumed. Often these are decorative elements, for example, mezzanine shelves or the base of a sliding wardrobe.
Use both plastic and metal components. The first are more popular today. They have a more attractive appearance, are not inferior to their metal counterparts in strength and allow you to hide fasteners.
Furniture corners are fixed with self-tapping screws to two mating parts. The fixture is hidden by latching the cover.
Shelf holders
There are a large number of these fasteners. Conventionally, they can be divided into 2 groups:
Each of these groups can be divided into the following types:
- with fixation;
- without fixation.
Shelf holders for chipboard are used to secure shelves in the cabinet. Fixation is provided by an eccentric. It consists of the fastener itself and the stem.
The shelf holder is installed in the body of the shelf, and the screw in the cabinet wall. To do this, drill holes in the wall and in the cabinet shelf. Often these are standard sizes. Using a Forstner drill, holes are made in the shelf for the holder. The hole in the wall - with a drill on wood. Make sure that the shelf supports are located 2 cm from the front and rear ends of the shelf.
In the prepared holes set shelf holder with a rubber hammer. This will ensure its reliable fixation inside.
Fixing shelves are characterized by an eccentric mechanism that provides a solid connection between the cabinet wall and the shelf. In addition, they play the role of additional reinforcement of the structure, increase its rigidity.
Shelf supports for glass are fixed with screws 16 mm long to the cabinet wall. The distance from the fastener to the rear or front end is at least 5 cm.
Shelf supports for glass with fixation are equipped with a special screw that securely fixes the glass and prevents it from falling out. Fasteners without fixation are presented in the form of a corner or rod.
Conclusion
The above-described fastening and coupling hardware is the most common in the manufacture of modern furniture. To ensure reliable fixation, rigidity and strength of the finished product, it is necessary to correctly mark and strictly follow the assembly sequence.
