Technical Specifications for Drop-In Anchors

There are numerous technical specifications that must be considered when using Concrete Drop-in Anchors. Considerations include diameter and material type, internal thread length, minimum edge distance and required hole size. The Concrete Drop-in Anchor is a great fastener option when working with flush mounting applications. The size of the Drop-in Anchor refers to the diameter of the standard UNC threaded rod or bolt to be used with this fastener. Once all these factors have been determined, you can find the expected holding values in the technical information below.

Length:

When setting the anchor flush with the base material: To determine the minimum bolt length required, add the internal thread length of the anchor, plus the thickness of the material to be fastened, plus the thickness of any washer to be used.

When setting the anchor deeper into the concrete:

Determine the minimum bolt length above and add the additional depth to the minimum anchor length.

Spacing:

The forces on a Drop-in Anchor are transferred to the material in which it is installed. If the anchors are installed too close together, it can cause an interaction of the forces, thus reducing their holding power. Minimum anchor spacing and minimum edge distances for the drop-in anchor are as follows: Anchor Diameter Spacing Between Anchors Minimum Edge Distance 1/4" 3-1/2" 1-3/4" 3/8" 5-11/16" 2-13/16" 1/2" 7" 3-1/2" 5/8" 8-5/16" 4-1/8" 3/4" 10-1/2" 5-1/4" When vibration or sudden impact is part of the load conditions, the spacing should be increased.

A safety factor of 4:1 or 25% is generally accepted as a safe working load. Reference should be made to applicable codes for the specific working ratio. Minimum embedment for satisfactory anchor performance is 4-1/2 bolt diameters. Deeper embedments will yield higher tension and shear capacity.

Permitted Development For Outbuildings

New rules regarding whether or not you can extend or add to your home without having to apply for planning permission for an outbuilding came into force on 1 October 2008. The New limits and conditions for what is allowed without the need for planning permission apply largely to the dimensions of the proposed addition, its position in relation to the house and its proximity to the boundaries of the property. Under the new regulations constructing an outbuilding that is not within designated land is considered permitted development, not requiring an application for planning permission, providing it meets the following limits and conditions: An outbuilding can not be constructed on land forward of a wall forming the principal elevation. Outbuildings and garages to be single storey with maximum eaves height of 2.5 metres and maximum overall height of four metres with a dual pitched roof or three metres for any other roof. Maximum height of 2.5 metres in the case of a building, enclosure or container within two metres of a boundary of the curtilage of the dwellinghouse.No verandas, balconies or raised platforms. No more than half the area of land around the "original house"* would be covered by additions or other buildings. In National Parks, the Broads, Areas of Outstanding Natural Beauty and World Heritage Sites the maximum area to be covered by buildings, enclosures, containers and pools more than 20 metres from house to be limited to 10 square metres. On designated land buildings, enclosures, containers and pools at the side of properties will require planning permission.

Within the curtilage of listed buildings any outbuilding will require planning permission.
