Installation: Drill pilot hole throughout the façade content and to the backup content to the specified embedment depth + one" employing suitable drill little bit(s) from the chart beneath. Drill should be in rotation-only method when drilling into delicate masonry or into hollow backing material.
Position blue conclusion from the Heli-Tie™ fastener while in the installation Instrument and insert the tie to the pilot hole.
With all different jobs wall ties need to carry out and all of the related polices for his or her use, it’s no wonder the dilemma ‘which wall tie do I take advantage of?
Ancon ties STF6 and TIM6 make it possible for for 24mm of frame shrinkage and they are appropriate for most timber framed buildings as many as 4 storey’s superior. The Ancon TFMT7 is specially made to allow for for better motion of approximately 65mm and therefore suited to bigger properties.
This could end in a wall tie on every single program of blockwork within 225mm of openings. Spacing may perhaps even so be calm if the joint provides a deboned tie spanning it.
Monumental historic properties dot town landscape and all far too typically, the toll in the a long time is visible on their own brick or stone façade. The restoration of those outer walls represents a common obstacle, in addition to a important expenditure. The façade may perhaps involve repairs for numerous types of[…]
While using here the SDS-furthermore rotohammer in hammer method, travel the tie until the suggestion on the set up tool enters the exterior floor with the masonry and countersinks the tie below the surface. Patch the opening while in the façade which has a matching masonry hanger.
When putting in, a slight quality should be applied to let humidity to cross the cavity towards the outer leaf. The drip Element of the tie really should position downwards and positioned near the centre of the open up cavity.
This element overcomes issues of safety and simplicity of use that may be encountered by before programs that use cumbersome, expensive and unreliable telescopic read more tools.
It might be tricky to recognize particularly when a wall tie has failed along with the extent of your failure but the most common signal is standard horizontal cracks showing up during the outer wall.
These type of techniques safe cavity walls to overhead buildings, even though accommodating vertical movement and so are applied in conjunction with one way sliding ties or two way sliding ties.
Commonly, ties are placed in the 450mm vertical, 900mm horizontal staggered spacing sample. Closer centres are occasionally adopted for bigger cavity or intensely loaded walls exactly where the declared resistance on the tie is in comparison to the lateral load to find out the tie density (Eurocode six).
When changing cavity ties using a remedial tying method it is important to Keep in mind that the substitution wall ties need to carry out a similar features as These demanded from ties Utilized in the properties development. They should:
With electric power-actuated fasteners, use exam fastenings to determine the lowest electric power amount which will insert check here the fastener to the correct depth and situation without the need of damaging the concrete masonry.
