Abstract
Abstract For roofing construction, a heat-insulation and water-proofing brick bond of the type comprising a plurality of rectangular heat-insulation bricks longitudinally and latitudinally aligned and firmly connected together by at least a binding member. The binding member is shaped like a channel bar, having two opposite leg portions extending from a flat top portion for fastening in corresponding grooves formed on the top edge at the four sides of the rectangular heat-insulation bricks, permitting the flat top portion to fit flush with the topmost edge of the rectangular heat-insulation bricks, so that the gap between each two rectangular heat-insulation bricks is covered against permeation of water.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
174 words
A heat-insulation and water-proofing brick bond comprising: a) a plurality of rectangular bricks longitudinally and latitudinally aligned; b) at least one binding member connecting the bricks together; c) each brick including a rectangular outer shell defined by a top surface and a cavity formed therein, the outer shell being provided with four elongate grooves extending along four sides of the top surface, each groove being partly defined by a projecting strip having a top edge disposed below the top surface of the outer shell; d) an inner heat insulation layer disposed in each cavity and an outer sealing layer sealing the inner layer; e) the binding member being in the configuration of a channel bar defined by a flat top portion and a pair of opposed leg portions extending from the flat top portion; and f) the leg portions of the binding member being engaged within adjacent elongate grooves of adjacent bricks to dispose the flat top portion of the binding member in a flush disposition with the top surfaces of the adjacent bricks.
Claim 2
Dependent Claim
174 words
A heat-insulation and water-proofing brick bond comprising: a) a plurality of rectangular bricks longitudinally and latitudinally aligned; b) at least one binding member connecting the bricks together; c) each brick including a rectangular outer shell defined by a top surface and a cavity formed therein, the outer shell being provided with four elongate grooves extending along four sides of the top surface, each groove being partly defined by a projecting strip having a top edge disposed below the top surface of the outer shell; d) an inner heat insulation layer disposed in each cavity and an outer sealing layer sealing the inner layer; e) the binding member being in the configuration of a channel bar defined by a flat top portion and a pair of opposed leg portions extending from the flat top portion; and f) the leg portions of the binding member being engaged within adjacent elongate grooves of adjacent bricks to dispose the flat top portion of the binding member in a flush disposition with the top surfaces of the adjacent bricks.
Claim 3
Dependent Claim
16 words
The brick bond of claim 1 wherein the outer shell is formed of reinforced plastic material.
Claim 4
Dependent Claim
19 words
The brick bond of claim 1 wherein the inner heat-insulation layer is formed of high density foamed plastic material.
Claim 5
Dependent Claim
15 words
The brick bond of claim 1 wherein the outer sealing layer is formed of concrete.
Claim 6
Dependent Claim
16 words
The brick bond of claim 1 wherein the binding member is formed of reinforced plastic material.
Claim 7
Dependent Claim
103 words
The brick bond of claim 1 wherein: a) a plurality of elongate grooves of adjacent bricks are aligned in the longitudinal direction and a plurality of elongate grooves of adjacent bricks are aligned in the latitudinal direction; b) a plurality of binding members engaged within the grooves aligned in the longitudinal direction, with each longitudinally aligned binding member being continuous along the longitudinal extent of the brick bond; and c) a plurality of binding members engaged within the grooves aligned in the latitudinal direction, with each latitudinally aligned binding member being of a length corresponding substantially to the length of a single brick.
Claim 8
Dependent Claim
22 words
The bond of claim 5 further including sealing material disposed between the binding members aligned in both the longitudinal and latitudinal directions.
