Foam block is a modern building material with a porous structure. The correct choice of fasteners for it will not only ensure the rational use of funds, but also make it possible to perform work with high quality in a short period of time.
Features and purpose
For the production of foam blocks, sand, water, cement and a foaming agent are used. The choice of fastening for this building material is influenced not only by the individual characteristics of cellular blocks, but also by the type of finishing work planned on the working surface of foam blocks. Particular attention must be paid to the load that will come on the wall from hinged furniture or different types of equipment.
When choosing foam concrete as the main building material, it is necessary to take into account its properties, technical characteristics and features . This type of product has a porous structure with low density, light weight, and a high level of hygroscopicity. The selected fasteners should be suitable for the type of work surface and the type of work planned.
Consumables not only fix the hinged interior items, but also strengthen the working structure and increase the percentage of possible load.
The fixing parts for this type of building material consist of a screw, a ring, a half-ring, a rim and an empty sleeve with a spacer. The teeth on the surface of the part are a reliable obstacle for scrolling the part during installation.
The length of the parts is from 3 to 5 cm, and the diameter is from 4 to 10 cm.
On the shelves of hardware stores, you can purchase fasteners prepackaged in special packages, or purchase individually. The number of units of parts in one package ranges from 50 to 1 thousand pieces.
Fasteners for foam blocks are of several types and are divided depending on their purpose and the following factors:
- scope - for interior and exterior finishing works;
- production material - metal and plastic;
- installation method - screwing in, hammering and installation by a chemical method.
Views
On the shelves of hardware stores Several types of fasteners are available for purchase:
- dowel;
- dowel nail;
- simple anchor;
- chemical anchor;
- screw M4;
- self-tapping screws;
- anchor bolt.
The dowel is the most demanded type of fastening material. The main feature is the creation of internal support when expanding inside the work surface.
Such a fastening element does not damage the cellular structure of the blocks.
Construction department consultants can offer dowels made of plastic or metal. Before buying, you must consider the type of finishing work. The assembly of consumables is carried out using a screwdriver, the regulator of which must be set to low speed.
Dowel nail is a fastening material used when working with dense blocks for walls . Feature - fast and reliable fixation of structures made of wood, metal and aluminum to the aerated concrete work surface. Dowel nails have a unique ribbed surface, which makes it possible to increase the level of fixation and distribute the load within the block. This feature of the details allows for facade work and the manufacture of suspended ceilings.
A simple anchor is a fastening element consisting of a spacer or a plastic dowel. Conventional anchors cannot be used for aerated concrete due to the porous structure of the building material.
Chemical anchor is an innovative type of fastening that has universal application.
The adhesive composition of a chemical anchor consists of several components:
- cement mortar;
- organic resin.
Fastening material advantages:
- high level of strength and reliability;
- resistance to low temperatures and atmospheric fluctuations;
- long period of operation;
- environmental Safety;
- ease of installation;
- universal application.
The disadvantages include the high price range
Screw M4 - an iron fastener with a spreading element made of metal. This mount can be used not only for foam concrete blocks, but also for a work surface made of dense aerated concrete.
Self-tapping screws for wood are simple and inexpensive fixing parts that allow you to fix objects with light weight.
For more secure fixation, you can drive a wooden dowel into the drilled hole.
Anchor bolt - an iron rod with a special thread and a locking device . It is used to perform work of increased complexity.
Particular attention should be paid to high-quality German products of the Fischer trademark. Fasteners from this manufacturer are made on innovative equipment from modern metal and plastic. Fischer is the first manufacturer of consumables for this type of work. German fasteners are universal parts with a wide range of applications, including for foam block 10x60 cm, and foam concrete 6x52 cm.
Criterias of choice
The correct choice and the ability to correctly apply fasteners will not only help to quickly and reliably complete the planned work, but also make it possible to rationally use the money set aside for repairs.
Features of the choice of fasteners:
- plastic dowels - fixing parts used to attach lightweight interior items;
- dowel nails are a consumable intended for through fastening of building materials both indoors and outdoors;
- metric screw - mount for installing windows, doors and technical equipment;
- metal anchor - a fastener for hanging furniture and equipment that are heavy;
- foundation bolt - a fastener used for work with a high level of stress and complexity;
- chemical anchor is a versatile consumable material with a wide range of applications.
When choosing an attachment, the planned load must be taken into account. The longer the size of the dowel, the greater the load it can withstand.
The most popular are metal parts made in Poland, Switzerland, Finland and France. Plastic and metal fasteners from Russian manufacturers are in high demand and have an affordable price and high quality.
When purchasing this type of product, you need to know the parameters that make up the price. These include:
- material;
- the size;
- manufacturer;
- availability of special packaging.
How to fix?
To fasten the waterproofing plates to the working surface made of foam blocks, use long facade dowel nails with a wide head. Plastic dowels - a spacer base with persistent collars. The collars not only secure the fasteners firmly, but also prevent them from falling out.
The installation of such a fastener consists of several stages:
- wall markings;
- drilling a hole corresponding to the length and width of the dowel, without taking into account the dimensions of the thread;
- cleaning the resulting cavity from construction debris;
- dowel installation;
- screwing in the screw to the desired length.
Installation of plastic fasteners takes a short period of time and does not require special equipment.
Screw-in consumables are a common fastener material. There is a special thread on the surface of metal or plastic dowels, with the help of which the dowel is fixed. Installation of this product does not require special skills and professional equipment and takes place by screwing the fastener into the prepared hole. The material and diameter of the dowel depends on its functional load.
Hammer-in dowels have large teeth that widen in the drilled cavity of the working base. Driving in fasteners should only be done with a rubber hammer.
A chemical anchor is the most reliable anchorage that can withstand a high level of stress.
The installation of such a device consists of several stages:
- drilling a hole in the form of a cylinder with a tapered cut;
- cleaning the hole from dust and building chips;
- installation of a cylindrical sleeve;
- filling the cavity with a special solution;
- mounting threaded studs.
It is forbidden to continue performing the following installation work until the construction adhesive has completely hardened.
The advice and recommendations of experienced builders will help to correctly hammer, as well as to correctly fasten interior items and equipment to the working surface of foam blocks.
Foam blocks are a lightweight building material, consisting of 80% of empty pores . Using conventional nails and anchors on a porous surface will not allow the attachment to be securely anchored and will lead to cracks in the work surface. Correctly selected consumable fasteners will not only ensure a secure attachment of the attachment, but will also increase the strength and reliability of the entire structure. Consultants of specialized building stores will help you make the right choice and purchase the necessary fixing elements that correspond to the planned work.
