The dowel for the foam block is often used to attach structural elements to it, as well as in the field of pipelines, electrical equipment, consoles with the help of wood screws. This product is made of plastic or a certain type of metal, while the mount for installation is formed of steel. A feature of this device is a special thread, due to which it is easy to screw the screws into porous surfaces.
Design
This part consists of two main parts:
- Non-working part, not participating in consolidation.
- A spacer element that changes size when a joint is formed.
Product Feature
The expansion bolt shield for the foam block eliminates the possibility of accidental unscrewing from the surface. The device itself, designed for installation, is made as a nozzle made of plastic for such a construction tool as a drill.
The expansion bolt shield for the foam block has unique characteristics, while maintaining operating properties in the temperature range from - 40 to +70 ° C. The device includes the presence of special ribs, in turn, crashing into the foam concrete and firmly holding the part.
Product Dimensions and Use
The expansion bolt shield for foam concrete blocks is excellent for products from various types of cellular concrete, as well as for hollow bricks. A characteristic feature of such a device is a spacer elongated part. The dimensions of this product are classified depending on the diameter of the screw and its own, as well as on the hole for the dowel. For convenience, the dowels are divided according to different letter categories. For example, for gas and foam concrete it is best to use types S, T, K.
Production Materials
This product is manufactured in three concepts: 2 categories for aerated concrete, metal and nylon.
The metal dowel (steel) is made of galvanized steel, which is resistant to corrosion. It is widely used in fixing gas pipes, blocks with voids and, of course, foam concrete. While screwing in the screw, the structure extends the limits of the hole and is secured with a ribbed surface.
The expansion bolt shield for foam concrete block - installation
These devices have gained immense popularity due to the ease of installation. To do this, a hole is drilled corresponding to the dimensions indicated by the manufacturer, and is cleaned qualitatively. Then, using a special nozzle, the dowel is inserted into the base until it stops. The element to be mounted is qualitatively attached using a metric screw.
Total
Currently, prices for such dowels are acceptable. On the market, these devices are quite often found of varying cost and quality. Therefore, everyone can choose the necessary dowel for the foam block individually. These products have gained immense popularity in the field of construction, repeatedly demonstrating their resistance to various loads.
