What is an anchor or anchoring of slabs slabs. Anchor is a special fastener made of brass, steel or other metal, necessary for fixing building elements and floor slabs. They are used for construction of both large and small buildings.
Anchoring - fixing floor slabs to outer walls and to each other. Anchoring floor slabs is designed to increase the service life, strengthening the strength and stability of the building.
Cons - large diameter connecting holes.
Pros - great reliability and ease of installation. Cons - overestimated requirements for the accuracy of the dimensions of the gaps.
Anchors for special applications:
There are many mounting options, it all depends on the material used. Anchoring of slabs to the walls of a brick house is carried out with steel elements in the form of G, stepping back 3 meters from each other. Be sure to concrete the metal at the end of the fastening work.
This will protect against corrosion.
If it is necessary to leave a channel for wiring, it is allowed to support the plates on adjacent panels. Here you need curved rods of class A-P from 12 mm. Composite anchors must be welded together. When fixing hollow-core slabs to block bricks made of silicate or foam, a steel anchor MKT with an internal thread is required.
In the process of bonding plates, it is necessary to take into account the recommendations described below.
Plates are laid in one plane. When laying blocks, leave space to the outer edge for mandatory insulation. Proceed to anchoring after completing the installation of the milestones. The panels should be connected by welding or by bundling the reinforcement protruding from them, as well as using an armored belt.
(option for slabs without lugs).
Avoid damaging the reinforcement when drilling holes in the plates. Do not use defective materials. Suspend work during precipitation.
Anchoring can be started immediately after installation of all parts.
It is advisable to prepare a plan before starting work. The anchor must be bent into a loop and hook the plate loop. After the maximum tension, the anchor can be welded to the slab hinges. Further, all the joints between the slabs should be immediately laid with cement mortar to avoid the ingress of debris, water and snow. If water does get in, you will have to drill holes from the bottom of the slabs and thus let the water drain.
What can cause fastener failure:
According to SNiP II-22-81 anchoring of slabs to different structures elements of buildings must be made in a certain order: Stone walls of the structure and supports are mounted with floor anchors, with a cross-sectional area of more than 0.5 cm2. The maximum allowed gap between slab anchors, with wall support is not more than 6 m.
Calculation of anchor elements is extremely necessary - in case of asymmetric change in the thickness of the supporting walls on which the slabs are laid, and also when the distance from the anchor to the anchor is more than 6 m. Typically, anchor ties are made of metal reinforcement with a diameter of 10 mm or more, and the anchoring length is more than 500 mm.
