1. Description of the Prior Art
Our research among patents revealed some systems that caught our attention: FR2544359 discloses a concrete block having a pair of upstanding channels surrounded by a large void.
CA2585790 discloses a pair of slabs interlocked by panels; male-female connexions are installed on top and bottom.
2. Objectives and Advantages
There is a need on the market of construction for a lightweight block, made of concrete, rock or wood material, assembled parallel, angularly, radial, T-shaped, shaft-shaped blocks of spaced apart components requiring a minimum of attachment. The blocks are insulated and use insulating substances, like mineral wool, fiber glass, air, or other substance with insulating properties, inserted in a space between each concrete block.
Our concept includes the following elements, lightweight parallel concrete, wood or rock blocks provided with means of attachment, such as:
folded pins directed on opposite angles and possibly connected two by two by thin metal crosses passing around pins which reinforce the ends during construction of walls. The rows are held by passing through metal rods which position any two blocks in a series to form a wall. Mortar or construction glue is used around the rods to strengthen them.
Means of an adhesive fibreglass wrapping the blocks partially or completely to maintain them attached. Furthermore, the fibreglass is attached on a top face of blocks by means of inside small channels filled with epoxy glue or filled with a wire of nylon or metal enclosing the fibreglass within the channels.
Means of attachment of blocks is to pour a strong glue on a surface of contact of blocks and to strongly stick them together.
Another means of attachment are crossed ties attaching blocks two by two, pressed in notches dug on upper or lower surfaces of the blocks, and on their sides.
The blocks are insulated by inserting an insulating substance or by a void space between each parallel block.
The present invention will be further understood from the following description with reference to the drawings wherein like numbers refer to like parts for easy identification.
An assembly 20 of at least two parts of blocks made of light weight, concrete or rock, parallel, angular, radius, T-shape, shaft-shape; namely a front part 24, a back part 22 and a center part 26 if a three part block. Between the parts, a void channel 28 or filled channel 30 with an insulating substance, like mineral wool. The channels provide a sound barrier and insulation. Different means of attachment can be used to maintain firmly two blocks together. Such means are: angular pins 34-34″, a reversed U pin 32, fiber blankets 49-50, adhesive construction glue, or means of crossed tie resisting to shear forces.
Angular pins 34, 34′, 34″, are installed in opposite directions of two parallelepiped to fix them together in the construction of a block.
An alternative disposition would be to use a reversed U pin 32 set perpendicularly between the parallel parts to maintain them parallel. The pins are ties angularly positioned from 5° to 175° degrees. The back part 22 is provided with an end groove 42 to receive metal strips 58 crossing from parallel part ends to strengthen the blocks. There is a central passage 48 for mortar surrounding a metal rod between an upper and a lower block. The upper face of the center part is pierced in the middle with an enlarged radius cup 46 to position the metal rods. The metal strips are used in assembling blocks in a wall.
Spaced parallel one to the other and having a filled channel 30 in between, the two parallelepiped are related by tie means orientated to maintain the parallelepiped directly facing each other.
Construction tie means may comprise a fibreglass blanket 49 comprising a knitting in three directions namely towards a left side, towards a right side and towards a transverse direction.
A third parallelepiped defines a central part 26 located between a front part 24 and a back part 22 all three separated by two filled channels.
Tie means may comprise two half blankets 50 each comprising a left orientated fibreglass tape 69, a right orientated fibreglass tape 70, an end fibreglass tape 71 and a transverse fibreglass tape 72. Tie means may comprise two pairs of angular pins 34 disposed to maintain the three parallelepiped at a parallel distance one from the other.
The construction block central part 26 may comprise a central passage 48 for passing a metal rod 54 with an enlarged radius 46 for receiving any second rod, the central part further comprising end grooves 42 passing a second block central part 26′. The central part (26) may be a structural strengthening part. Wire means 76 may comprise means for retaining a front surface from falling apart.
The construction block may also comprise rubber spacers 74 added to the fibreglass blanket in a transverse direction with spacers touching respective walls of the parallelepiped when subjected to a transverse blow. The construction block may have as filled channels 30 hot & cold insulation 78. The construction block can be wrapped in a fiberglass blanket held in place by an adhesive disposed over an external face of the parallelepiped and over a face matching a filled channel. A parallelepiped may comprise a grooved channel for holding tension wire means comprising a nylon wire, a steel wire to cover the blanket and keep it in place within the groove channel. An epoxy spread may be used above or below the blanket.
Another means of attachment are crossed ties 60 in a shape of a rectangle wherein opposite corners are joined by straight webs 63 for avoiding shifting when the blocks are subjected to oscillating during wind, storm, landslides or earthquake. Pegs 61,61′ are provided to mesh with critical positions in the blocks for stable junctions. The tips are be in a rectangular 61 or a circular 61′ shape.
With such attachments, the blocks are made with notches 21′ on upper or lower surfaces of the blocks, or and on their sides. The crossed tie are then pressed inside the notches 21′ of the block. The crossed ties are provided with means of lifting 59 to lift the assemblage of blocks with crossed ties. Many external features could be provided with the blocks, namely: colored, rock, marble and architectural design. Two blocks joined with a means of attachment could be of different material, such as a marble block joint with a rock block. Or a cement block joint with a wood block.
The crossed ties 60 can comprise a retainer hook 67 destined to hook on rubber rings to keep parallel back and front blocks together when erecting sound barrier walls.
The insulation may be a high density rigid board which uses adhesive on both sides and is glued against each part 22, 24, 26. The insulation may also be wrapped in a plastic film 84 which holds the insulating matter in a rigid state. The plastic film is also glued against the parts.
The construction block parallelepiped may be of cementitious material. Parallel blocks may be angled, curved, or crosslike.
It is to be clearly understood that the instant description with reference to the annexed drawings is made in an indicative manner and that the preferred embodiments described herein are meant in no way to limit further embodiments realizable within the scope of the invention.
