Description

ADJUSTABLE PAVING LAYER This invention relates to an adjustable paving layer. The method used in the laying of paving slabs is for a line to be set between the desired levels to be laid with paving, sand or other suitable material is spread on the base, using a trowel or similar flat piece of wood, the slab is then laid in position and bedded down with a tamper, the slab or paving may be lifted and relaid several times before the right level is achieved, with no assurance that the base is not hollow thus being liable to break when pressure is applied to the surface of slab or paving.
According to the present invention, there is provided an adjustable paving layer comprising a body in the form of a straight edge, an adjustable leveller to prepare base for paving, the body and adjustable leveller being adapted to allow controlled change of level, means for releasably securing adjustable leveller to body a right angle on adjustable leveller to accurately gauge paving thicknesses, means in the form of bedding depth adjusters to set for bedding depth and handles to control adjustable paving layer during levelling operation.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawing in which: Fig. No. 1 Shows exploded drawing of the paving layer with numbered parts Fig. No. 2 Shows slab being gauged for thickness using the right-angle on the leveller Fig. No. 3 Illustrates the paving layer being used to prepare base for paving Fig. No. 4 Displays paving layer in a controlled change of level in a upward incline A controlled change of level in a downward incline is attained by moving the leveller 23 cooperable with the body 16 until bottom edge of the body 16 is parallel with the stringline 22 Refering to drawing in Fig.No. 1 the adjustable paving layer comprises a body 16 in the form of a straight edge to which a adjustable leveller* is releasably secured by hand screws 14 co-operable with slots 19 in the body 16 and slots 20 in the leveller and a hole in a tapered metal plate 17.
The body being adapted co-operable with slots 19 in the body and slots 20 in the leveller } to pivot on the screwed centre pin 10 either in an upward incline or a downward incline. After a controlled change of level, the body 16 is realigned by placing the edge of the body against paving surface until a straight edge is attained the hand screws 10 are re-tightened.
To gauge the thickness of paving to be laid the edge of the slab is placed between the edge of the body 16 and rightangle 21 with the slab firmly held between the two surfaces of and the hand screws 14 are re-tightened the bedding depth is preset by screwing round flat headed screw 12 until tight into tapped hole in the edge of the body 16 the levelling operation is controlled by the handles 15 on the body. For a controlled change of level the bottom edge of the body 16 is moved until it is parallel with the string line 22.
