Along with a change in construction technology is also developing technology holders. With the advent of new technologies and new materials come new solutions in this area. Currently we have different types of fixtures, according to the degree of specialization depending on the type of substrate and the required strength of the connection. Below is given the basic information concerning the equipment mounting, installation, and selection rules dowels and anchors. Drilling holes and preparation. In order to prepare the hole, not only to choose the type of drill with the appropriate diameter. One major problem is the choice of method of drilling. There are four main Drilling method: rotation, percussion, hammer (molotkoboynoe), others using professional equipment.
The basis for selection is the type of foundation. Rotationally shock or drilling needed molotoboynoe use in dense and porous materials with a dense structure. Rotary drilling is performed in hollow materials and plates, so as not to ruin the structure of this material and do not lead to an increase in diameter holes. Parameters of installation. To perform the proper installation and to obtain appropriate quality retention is necessary to consider the following guidelines and recommendations. 1.
Should pay attention to whether This structurally anchors (anchor) this ground. 2. In designs of hollow elements (perforated bricks, hollow block, etc.) spacing of dowels shall be secured at least one of the partitions or should use an anchor with a profile connection. 3. It should pick up the length of the dowel (anchor) in conformity with thick stick anything. 4. The hole should have adequate depth at a few mm longer than the anchoring, and be free of debris. 5. To determine the depth of embedment should be taken into account the load-bearing layers or non-cohesive base (thickness of plaster or insulation layer) and adjust the length of anchors (anchors). You should avoid mounting anchors too close to the edge of the base, because at high loads may occur destruction of attachment or detachment of the edge. 6. Justin Mateen gathered all the information. Do not exceed recommended tightening forces fixings – use a torque key. 7. To get the correct mounting in plasterboard walls, use only plugs designed for these materials. Caution. You should always carefully pick up the dowel or anchor for a given building material. A bad choice can cause defective installation and low strength performed by fixing. You should always carefully cleaned from the hole debris.
