Abstract

A prefabricated reinforced brick panel has a plurality of bricks arranged in a spaced-apart array with mortar between the bricks. The array comprises a number of superimposed rows of bricks. The bricks in each row are staggered relative to the bricks in each adjacent row of bricks. Each brick has a number of vertical through holes extending between a top and a bottom of the brick. These through holes are aligned in the array and vertical reinforcing bars are inserted into aligned holes and extend between a top and a bottom of the panel. Two offset vertical reinforcing bars pass through each brick. Transverse reinforcing bars are mounted in the mortar between rows of bricks. <Figure 1>

Detailed Description of the Preferred Embodiments Referring to the drawings and initially to Figs. 1 to 6 thereof, there is illustrated a cladding panel according to the invention, indicated generally by the reference numeral 1. The cladding panel 1 comprises a plurality of bricks 2 stacked in a number of rows 3. Vertical reinforcing bars 4 extend through the bricks 2 between a top 5 and a bottom 6 of the panel 1. Mortar 7 is provided between the bricks 2. Transverse reinforcing bars 12 are embedded in the mortar 7 between each row 3 of the bricks 2.

Referring to Fig.10, the bricks 2 are conventional building bricks with a number of spaced- apart through holes 8 extending between a top face 9 and a bottom face 10 of each brick 2. Each brick 2 has a length L of 215mm, a width W of 105mm and a depth D of 65mm. Each hole 8 has a diameter of 20mm. As can be seen in the drawings, two rows of five spaced-apart holes 8 are provided. The vertical reinforcing bars 4 extend through the bricks 2 in each row of bricks between the top 5 and bottom 6 of the cladding panel 1, as can best be seen in Fig. 3.

It will be noted that all of the bricks 2 in the cladding panel 1 are engaged by the vertical reinforcing bars 4. Each full brick 2 is engaged by two of the vertical reinforcing bars 4. One of said two vertical reinforcing bars 4 engages in one of the -7holes 8 in the front row of holes in the brick 2 and the other vertical reinforcing bar 4 engages in one of the holes 8 in the rear row of vertical holes 8 in the brick 2. Thus, effectively, a front row of spaced-apart vertical reinforcing bars 4 is provided, together with a rear row of spaced-apart vertical reinforcing bars 4 extending through the panel 1. Also, the two vertical reinforcing bars 4 which engage each brick 2 are offset being spaced-apart at opposite sides of a central longitudinal axis X of the brick 2 and are also laterally offset in each brick 2 engaging longitudinally spaced-apart holes 8 in the brick 2 as best seen in Fig 5.

As shown in Figs.1 and 4 the bricks 2 in each row 3 of bricks 2 are offset from the next adjacent row 3 of bricks 2 in similar fashion to a conventional brick wall construction.

As best seen in Fig. 5, pairs of transverse reinforcing bars 12 are mounted between each row 3 of bricks 2 and extend between opposite ends 16, 17 of the wall panel 1, being embedded in the mortar 7. Such pairs of transverse reinforcing bars 12 may be provided between some or all of the rows 3 of bricks 2, as required.

Although not shown in the drawings, tie elements may be mounted on a rear face of the cladding panel 1 or embedded in the cladding panel 1 and projecting outwardly of the rear face of the cladding panel 1 for connection to a support structure on a building for mounting the cladding panel 1 on a building structure.

Referring now to Fig. 7, another prefabricated reinforced masonry panel according to a second embodiment of the invention is shown and indicated generally by the reference numeral 20. Parts similar to those described previously are assigned the same reference numerals. In this case, a number of openings 21 are provided in the wall panel 20 for reception of windows.

Referring now to Fig. 8, another prefabricated reinforced masonry panel is shown and indicated generally by the reference numeral 30. Parts similar to those described previously are assigned the same reference numerals. In this case, a pair of spacedapart brick panels 1 are provided between which is sandwiched an intermediate layer 31. Said intermediate layer 31 may comprise insulation or alternatively it could comprise a reinforced concrete layer. 7G7I5 -8Referring to Fig. 9, there is shown another prefabricated reinforced masonry panel assembly, indicated generally by the reference numeral 40. Parts similar to those described previously are assigned the same reference numerals. In this case, the masonry panel 40 comprises an outer brick panel 1, an intermediate insulation panel 41 and an inner panel 42 of reinforced concrete material. The outer brick panel 1 and inner reinforced concrete panel 42 are tied together in any suitable fashion and the insulation material 41 mounted therebetween. Upright T-section posts 45 are associated with the panels 40. A laterally extending tongue 46 on the post 45 engages in an associated groove 47 formed at each end of the masonry panel 40. Thus, a masonry panel 40 can be mounted between a pair of the pillars 45 in constructing and supporting a wall formed of the panels 40.

Referring now in particular to Figs. 11 to 16, a method for manufacturing the prefabricated reinforced brick panels 1 will be described. A plurality of bricks 2 are laid face down on a horizontal support surface 50 of a panel forming bed 51 in a spaced-apart array leaving gaps 52 between the bricks 2 for reception of the mortar 7. Said array comprises a number of juxtaposed rows of bricks 2, the bricks 2 in each row of bricks being staggered relative to the bricks in each adjacent row of bricks 2. The through holes 8 in the bricks are overlapped in adjacent rows of bricks 2 when forming the array on the bed 51. Rubber spacer strips 53 are mounted in the gaps 52 between the bricks 2 on the bed 51 and seal between the bricks 2 and the bed 51. A number of spaced-apart outer vertical reinforcing bars 54 are inserted through the overlapping holes 8 in the bricks 2 between a top row of the bricks 2 and a bottom row of the bricks 2 in said array of bricks on the bed 51 (Fig. 12). Next, a first transverse reinforcing bar 12 is laid across the outer reinforcing bars 54 (Fig. 13) along at least one of the gaps 52 between the rows of bricks 2. Then a number of inner vertical reinforcing bars 56 are inserted through the holes 8 in the bricks 2 to extend between the top row of bricks 2 and the bottom row of bricks 2 in the array of bricks mounted on the bed 51 (Fig. 14). A second transverse reinforcing bar 12 is mounted on top of the inner reinforcing bars 56 (Fig. 15) in the gaps 52 between the rows of bricks 2. A liquid mortar is prepared from a mixture of fine sand, cement and water. The liquid mortar is poured into the gaps 52 filling the gaps 52 and the holes 8 in the bricks 2. The mortar 7 is allowed to set and then the prefabricated reinforced ¢10 707 95 -9masonry panel 1 is removed from the bed 51.

In use, a number of the cladding panels 1 are mounted on an exterior of a building structure to provide a brick wall fagade on the building structure. Any suitable mounting means may be provided for mounting the panels 1 and such mounting of cladding panels on support structures is well known in the art.

The invention is not limited to the embodiments hereinbefore described which may be varied in both construction and detail within the scope of the appended claims.
