Introduction MAINEPORT LTD manufacture a standard range of anchor bolt assemblies for industrial and civil engineering applications. This catalogue will enable you to specify, select, purchase and install the bolting you require for your application. We also supply special bolting arrangements manufactured to customers’ requirements and any combination of length and projection for standard units, in 10mm increments.

Product Application Guide The Type ‘F’ anchor bolt (Fig. 1) is designed for the fixing of structures, equipment and skidmounted units to reinforced concrete floors. The sleeve and anchor plate assembly is cast into the floor and access is required from above and below to fit the bolt after installation of the plant item. The Type ‘S’ anchor bolt (Fig. 2) is suited for fixing heavy structures and equipment such as vessels, chimneys, and large machines to concrete foundations. The whole assembly is cast in with the concrete reinforcement and consideration must be given to the location and stability of the bolting during the casting process (see installation Guidance Notes). The Type ‘SC’ anchor bolt (Fig 2a) incorporates a protective cap with Type ‘S’ assembly. The cap’s purpose is to prevent concrete from setting around the bolt lies below the top of concrete level. This design protects the bolt thread from damage and facilitates equipment installation or erection of the structure. After installation the bolt is pulled upwards through it’s mating hole, using a 10mm stud bar and the M10 tapped hole in the top of the bolt. This solution is more economic than other designs which incorporate extension studs, couplings and keep bolt s. The Type ‘J’ anchor bolt (Fig. 3) is suitable for lighter equipment applications and is cast into concrete with a ‘pocket’ to allow minor adjustment. This design is an economic alternative to proprietary expanding sleeve-type bolts which are installed after casting the concrete.

Design Guidance Notes The interface between a concrete floor or foundation and the structure supported is an important design consideration which brings together civil, structural and mechanical engineering disciplines. There may also be a contractual interface and therefore it is essential that the design considerations are co-ordinated in a systematic manner, for example in accordance with BS 5750 Part 1. The following areas must be considered: •

• •

•

Accessibility, dimensional tolerance and movement to enable the requirements to be achieved in practice. (See construction Guidance Notes). Static and dynamic loadings imposed by the structure supported, transferred to the foundation. Bedding-in, packing, grouting and filling of voids between various elements of the composite structure. Protection from adverse service conditions during the design life.

The economy of the design in terms of meeting performance criteria is of course an overall important consideration: MAINEPORT LTD anchor bolts will form an integral part of the most economic design solution.

Bolt Diameter The bolt diameter is normally determined from the loadings imposed by the structure supported. Reference should be made to recognised standards e.g. BS 5950 for further information and guidance.

Bolt Length The embedded length of the sleeve and the anchor bolt is normally determined by the properties of the concrete into which it is cast, and the bolt loading. The MAINEPORT LTD standard anchor bolts are designed to transmit the full tensile load specified in BS 4190 (Gr 4.6) in accordance with BS 5950, assuming a grade C30 concrete to BS 8110.

Corrosion Positive means of minimising corrosion should be specified, and corrosion allowances not relied upon to achieve the design life. Bolt sleeves and pockets should be filled with a suitable inert material, and sealed to prevent moisture ingress.

6


Packing Packing shim and location details should be specified if they form part of the permanent design solution.

Grouting Grouting details should be specified on the construction drawing. Adequate access for bedding and filling of materials should be provided.

Installation Guidance Notes MAINEPORT LTD Anchor bolts over 24mm dia. are provided with M10 tapped holes to facilitate lifting into position with a lifting eye. Bolts must be accurately positioned to the specified tolerances for line, level and plumb. We strongly recommend the use of a template supplied by the equipment manufacturer where anchor bolts are in a close matrix or pitch circle configuration. Substantial temporary timber or steel structures may be required to support the assemblies, and consideration must be given to preventing movement during the pouring of concrete. The assembly may be wired to the reinforcement cage or shuttering bolts to hold it steady, or welded struts may be positioned to hold the bolts rigid. A final check on positioning should be carried out prior to the pouring operation. Sleeves and cast pockets should be cleaned out, and bolts checked for freedom of movement where applicable, prior to placement of the equipment or structure to be supported.
