Description

Flexible, foldable brick sheet and roller, and palletizing method of it.

Technical field

The present invention concerns a sheet of Flexible, foldable and roller bricks, manufactured in dry and Tensile resistant, suitable, for example, for the construction of architectural elements preferably of exposed brick, such as land coverings, floors, walls, roofs etc., and formation of ventilated walls.

Background of the invention

WO international patent application 2008139008 unveils a flexible brick sheet that it comprises a plurality of interwoven flexible rods forming a grid-shaped fabric, and a plurality of bricks provided with clamping configurations crimped with the minus some of said rods to retain said bricks in said grid. The rods are advantageously corrugated to immobilize the crossing points thereof in the grid. The bricks have clamping configurations, for example in channel shape, at its ends and during the manufacturing process are attached to the rods that form the fabric warp interspersed between the rods that form the plot, which they act as positioning rods to link the tissue and restrict the movements of the bricks in it. Optionally the grid includes armor rods arranged like warp rods in the spaces between bricks.

While this sheet of bricks in a fabric of rods has given an excellent result and is useful in many applications, however, has some limitations, for example, although the brick sheet can be rolled up in the form of a coil on a core for storage and transport, the existence of warp rods in the fabric of rods does not allow the brick sheet can be folded or folded, and this hinders its palletizing.

FR 2 744 471 describes an element prefabricated made with bricks with holes, stacked and placed in a breaker arrangement and with the holes aligned. Washers are sandwiched between the bricks aligned with the holes in the bricks to leave some separations corresponding to horizontal joints. Nail rebar bars are passed through the aligned holes of the bricks and washers and a sealing material is injected from the top of the architectural element to inside the aligned holes of the bricks and the washers, immersing the bars of armor. The holes of the bricks are formed perpendicular to their major faces since the prefabricated element is intended to work at compression.

This prefabricated element generally has the shape of a straight wall section, although it is also planned that it may have, for example, the shape of a section of curved wall or in angle, a pillar, a bench, etc. However, whatever its form, It has the disadvantage of being rigid due to the existence of sealant material adhered to the interior surfaces of the holes in the bricks and reinforcement bars, and by consequently it is not foldable or roll up and its dimensions are necessarily limited due to storage requirements, handling and transportation Another drawback of this element prefabricated is that due to its own constitution requires a disposition of the breaker bricks or a openwork arrangement, and does not support a grid layout. Further, the tensile strength of the prefabricated element in a direction perpendicular to the rebar bars is limited to the tensile strength of the bricks since these are the only binding elements in such direction. Given that the tensile strength of ceramic bricks is relatively low (for example compared to its resistance to compression), the prefabricated element must be handled with certain precautions to avoid breakage and its applications are significantly limited.

Exhibition of the invention

A first aspect of the present invention Contributes to solve the above and other inconveniences providing a flexible, foldable and roll-up brick sheet, comprising a plurality of bricks provided with about holes and arranged in adjacent rows with said holes mutually aligned, separating elements arranged to provide separation spaces between said rows of bricks, rods passed through the aligned holes of said bricks, and retaining means for retaining said rods inside the holes of the bricks. Rods They are sized to rotate and slide freely within the holes in the bricks and said retention means are configured to restrict a movement of the rods in a axial direction of the holes and to allow a free rotation of the rods at least inside the holes of the bricks belonging to alternate rows.

The previous composition responds to a simple realization in which the bricks themselves, which must be on the brick sheet in an arrangement to joint breaker, either compact or openwork, cooperate with the rods to form a chain that can have a width of several rows of bricks and an indefinite length. The mentioned separating elements may be formed in this case by some washers through whose holes are inserted the rods, or by protrusions formed on at least one of the faces of the bricks to make contact with another brick adjacent.

Another more complex embodiment of the sheet of bricks includes, in addition to the components described above in relationship with said simple embodiment, a plurality of links adjacent to one or more of the brick rows. Every one of said links has two holes through which two of the adjacent rods are inserted. The links and the bricks are arranged so that they cooperate with the rods to form a chain, where the links assume totally or in large tensile stresses in the longitudinal direction of the chain preserving at least partly the bricks of such efforts This composition with links allows to arrange the bricks in the brick sheet according to an arrangement in grid, in addition to breaker arrangements compact and a previously broken joint breaker mentioned for simple realization.

The two holes of the links are separated by a certain distance according to the form and dimensions of the bricks to provide spaces of separation of a desired extension between the bricks of each row, and to allow folding or folding of the sheet of bricks by turning 90 degrees or more around any of the rods without the bricks interfering about to others. Here, the mentioned separator elements are formed by the links, which have, in at least some regions around the holes, a thickness sized to provide spacing spaces of a desired width between the rows of bricks. Obviously, some links can be replaced by washers of an equivalent thickness in one or more of the spaces of separation between the rows of bricks provided that remaining links and / or the bricks guarantee the benefits Functional and mechanical brick sheet.

Both in simple realization without links as in the complex embodiment with links, the said means of retention can be formed, for each rod, by a plug annular, preferably of an elastic material, such as a elastomer, disposed between an outer surface of the end of the rod and an inner surface of the brick hole or link hole. Said annular plug can be formed, for example, injecting a sufficient amount of silicone into liquid or pasty state inside the corresponding brick holes located on one or both side edges of The brick sheet. This annular plug has the advantage of allow the rod to be retained without protruding from the hole of the brick Alternatively, the retention means comprise, in at least one side edge of the brick sheet, an element of connection arranged in the longitudinal direction and joined by its ends to ends of two projecting adjacent rods of the bricks. This connection element can be fixed, by example by welding or adhesive, to the ends of the rods, or it can be integrally formed with the two adjacent rods, so that the two rods and the connecting element are obtained from a single piece of bent rod in the form of "OR". Another alternative way for retention means comprises, at least one side edge of the brick sheet, a stop fixed at one end of the protruding rod of the brick. Optionally, a link may be located adjacent to the outer face of the brick located on the side edge of the brick sheet, in which case said stop is fixed one end of the protruding link rod. Respectively in each In this case, the stop will be sized so as not to pass through the hole in the brick or link hole.

Throughout this description the term "brick" to refer generically to a essentially orthopedic body, made primarily of a ceramic material, a concrete material, or a stone material, although other materials are not discarded. In an example of usual embodiment of the present invention, the bricks of orthopedic shape have two opposite wide faces and two faces narrow opposite elongated in a longitudinal direction and others two opposite narrow faces elongated in a transverse direction, and the holes extend parallel to the direction transverse and have openings on both sides of said two faces narrow opposite elongated in the longitudinal direction. This means that in this embodiment the brick sheet has a relatively thin overall thickness, equivalent to the smallest dimension of the bricks, while these present in sight Your biggest faces. However, square-plan bricks, or of cubic configuration, or even elongated in the direction transversal, are also within the scope of the present invention.

The brick sheet preferably has a dimension in the longitudinal direction and one dimension in the cross direction, where the rows of bricks are arranged parallel to said longitudinal direction and the rods are arranged parallel to the transverse direction. Thanks to this arrangement, the brick sheet can be folded or zigzag folded around one or more of the rods to reduce the space occupied by it in the direction longitudinal, which is especially advantageous when the dimension longitudinal is significantly longer than the dimension transversal, without forgetting that it can also be rolled up in the form of coil over a core. It will be understood however that a sheet of square or even cross-sectional bricks longer than the longitudinal dimension is also within the Scope of the present invention.

According to a second aspect, the present invention provides a method of palletizing a brick sheet Flexible, foldable and roller. The method comprises first provide a sheet of bricks according to the simple embodiment of the first aspect of the present invention described above or a brick sheet according to the complex embodiment provided with links described above. Next the method comprises place a portion of the brick sheet on a pallet, and then fold or zigzag the brick sheet around one or more of the rods to form two or more sections of bricks overlaid on said pallet. A mode of carrying out the method of the invention comprises supporting vertically the brick sheet with a bottom edge of the same adjacent to a side edge of the pallet, and make a movements of vertical descent of the brick sheet in relationship with the pallet in combination with reciprocating movements horizontal of the brick sheet in relation to the pallet. The mentioned horizontal reciprocating movements will logically have a selected amplitude according to the dimensions of the pallet. For vertically support the brick sheet and make said vertical and horizontal reciprocating movements of the blade of bricks in relation to the pallet can be used for example a forklift, a crane, or other similar machine, although alternatively other means could be used to move the sheet of bricks, move the pallet, or move both in combination.

Detailed description of some embodiments

First, with reference to Figs. 1 a 3 and to Figs. 4 to 6 describe two simple embodiments of a 10 flexible, foldable and roll-up brick sheet 10 present invention In both simple embodiments, the one mentioned brick sheet 10 comprises a plurality of bricks 1 generally equal to each other arranged in adjacent rows parallel to a longitudinal direction. Each of the bricks 1 (Figs. 3 and 6) have the shape of a body essentially in the form of elongated orthohedron in said longitudinal direction, and has two opposite wide faces 31 and two opposite narrow faces 32 elongated in the longitudinal direction and two opposite narrow faces 33 elongated in a transverse direction. Each brick 1 comprises a pair of through holes 1 extending parallel to said cross direction from one to the other of said two narrow faces opposite 32 elongated in the longitudinal direction. The bricks they can have other holes, holes or openings in addition to the mentioned holes 1a.

In the brick sheet 10 shown in the Figs. 1 and 2, the rows of bricks 1 are arranged with the 1 bricks in a breaker arrangement compact, while in the brick sheet 10 shown in the Figs. 4 and 5, the rows of bricks 1 are arranged with the 1 bricks in an openwork breaker arrangement, that differs from the disposition to breaker compact by leaving a considerable gap wide between the opposite narrow faces 33 elongated in the cross direction of adjacent bricks 1 of the same row. These spaces of separation between bricks of the same row are determined by the distance between holes 1 to in relation to the total length of the bricks 1, being such distance between holes 1a longer in arrangement a openwork breaker that in the disposition to compact breaker for the same length of brick 1. In both arrangements the respective holes 1a of the bricks 1 of the adjacent rows are mutually aligned, and through these aligned holes 1a of the bricks 1 are passed some rods 2. Some are provided retention means for retaining said rods 2 within the holes 1a of the bricks 1 and separating elements for provide separation spaces between the rows of bricks 1, which will be described in detail below.

The rods 2 and the holes 1a of the bricks 1 are sized so that the rods 2 can turn and slide freely inside the holes 1a, and the mentioned retention means are configured to restrict the movements of the rods 2 in the transverse direction, is that is, in the axial direction of the holes 1a, and to allow a free rotation of the rods 2 at least within the holes 1a of the bricks 1 belonging to alternate rows, so that the bricks 2 cooperate with rods 2 to form a chain flexible with a width corresponding to a number of rows of bricks 1 and a length only limited by the possibilities of brick blade handling. This chain constitutes the sheet of bricks 10, which can be folded or folded around one or more of the rods 2 to adapt to different shapes, surfaces, contours and configurations. Various media examples retention will be described in detail below in relation to Figs. 17, 20, 21 and 22.

Since the brick sheet 10 is elongated in the longitudinal direction, that is, it has a dimension in the longitudinal direction significantly longer than a dimension in the transverse direction, and since the rows of bricks 1 are arranged parallel to the direction longitudinal and that the rods 2 are arranged parallel to the transverse direction, the flexibility of the sheet of bricks 10 can be used to reduce the space occupied by it in the longitudinal direction to facilitate its handling and storage. For example, the brick sheet 10 can be folded in zigzag by turning 90 degrees or more around several of the rods 2, or it can be rolled around a nucleus. To facilitate folding, the bricks 1 may include chamfers 34 between one of the opposite wide faces 31 elongated in the longitudinal direction and the two narrow faces opposite 33 elongated in the transverse direction.

In the simple embodiment shown in Figs. one to 3, each brick 1 comprises protrusions 7 formed in their opposite narrow faces 32 elongated in the longitudinal direction. These projections 7 are positioned to make contact with one of opposite narrow faces 32 elongated in the direction longitudinal another brick 1 of an adjacent row. So, the projections 7 act as the aforementioned separator elements for provide adequate separation spaces between the rows of bricks 1.

In the other simple embodiment shown in the Figs. 4 to 6, the separating elements are formed by washers 6, of a thickness corresponding to the separation space desired, arranged between the rows of bricks 1. Each washer 6 has a hole aligned with the holes 1a of the bricks 1 adjacent, and the rods 2 are inserted through the holes 1a of the bricks 1 and the holes of the washers 6.

It will be understood that alternatively you can form a sheet of bricks 10 with a configuration to compact seal breaker as shown in Fig. 1 using as separating elements washers 6 as shown in Fig. 4 instead of the protrusions 7 in the bricks 1, e conversely a brick sheet 10 can be formed with a openwork breaker configuration as shown in Fig. 4 using as projecting separating elements 7 in the bricks 1 as shown in Fig. 1 instead of washers 6.

With reference now to Figs. 7 to 10, at Figs. 11 to 14, and to Figs. 15 and 16 three embodiments are described complex of flexible, foldable and flexible brick sheet 10 of the present invention. The brick sheets 10 of complex embodiments are analogous to brick sheets 10 of the simple embodiments described above except that brick sheets 10 of the complex embodiments include in addition to the bricks 1, the rods 2, the separating elements (in this case optional) and the retention means, a plurality of links 3 adjacent to one or more of the rows of bricks 1. Each link (see Figs. 10 and 14) has two holes 3a to through which two of the rods 2 are inserted adjacent, so that links 3 and bricks 1 cooperate with the rods to form the chain that constitutes the sheet of bricks. The links 3 can be located between each two rows of bricks 1 and have a suitable thickness to act as the separation elements between the rows of bricks, or they can be willing to leave vacancies that can be filled by example, by 6 washers analogous to those described in relation to Figs. 4 and 5 to act as separation elements in combination with links 3.

In the complex embodiment shown in Figs. 7 and 8, the rows of bricks 1 are placed with the bricks 1 in a compact breaker arrangement, using bricks like the one shown in Fig. 9, which are analogous to that described above in relation to Fig. 3 but without the projections 7, in combination with links 3 as shown in Fig. 10, which have the two holes 3a located at the same distance as holes 1a of brick 1 shown in the Fig. 9.

In the brick sheet 10 shown in the Figs. 11 and 12, the rows of bricks 1 are placed with the 1 bricks in an openwork breaker arrangement, using bricks similar to those described above in in relation to Fig. 6, in which the holes 1a are more separated from each other than in brick 1 shown in Fig. 9, although both bricks have the same external configuration, in combination with links 3 as shown in Fig. 14, the which have the two holes 3a located at the same distance as the holes 1a of the brick 1 shown in Fig. 6.

The incorporation of links 3 allows additionally place the rows of bricks 1 with the bricks 1 in a grid arrangement like that of the complex embodiment shown in Figs. 15 and 16, which cannot be achieved with simple realizations. To form this brick sheet 10 with a grid arrangement bricks 1 such as the shown in Fig. 9 in combination with links 3 such as shown in Fig. 10. Here, in some sections only the links 3 cooperate with rods 2 to form the chain flexible that constitutes the brick sheet 10. Note that using the same bricks 1 of Fig. 9, the same links 3 of Fig. 10 and the same rods 2 can both form the brick sheet 10 with the arrangement to compact seal breaker of Figs. 7 and 8 as the brick sheet 10 with the grid arrangement of Figs. 15 and 16 only by varying the placement of the bricks 1.

Alternatively, to form the sheets of bricks 10 according to any one of the two embodiments simple ones shown in Figs. 1 to 3 and 4 to 6 or of the three complex embodiments shown in Figs. 7 to 10, in Figs. 11 to 14 and in Figs. 15 and 16 bricks can also be used 1 as shown in Fig. 13, which include a first pair of holes 1a located in positions suitable for the disposition to compact breaker and for grid arrangement and a second pair of holes 1b located in positions suitable for the provision to open-joint breaker, which allows to obtain sheets of bricks of different arrangements with a single type of brick 1 only choosing the right pair of holes 1a or 1b For each case.

In Figs. 20, 21 and 22 several are shown alternative examples for said retention means. In the example of Fig. 20, the retention means comprise, in al minus a side edge of the brick sheet 10, an annular plug 4 disposed between an inner surface of the hole 1a of the brick 1 and an outer surface of the end of the rod 2. The ring plug 4 is preferably made of an elastic material, such as an elastomer, which grasps frictionally on surfaces of rod 2 and hole 1a of brick 1, and more preferably from a silicone applied by injection in a state liquid or pasty inside hole 1a in the presence of the rod 2. Ring plug 4 provides rod retention enough for a majority of applications and has the advantage of retain the rod 2 inside the hole 1a of the brick 1 without the rod 2 protrudes laterally from the brick 1, as it is shown in Fig. 20. The ring plug 4 hinders the free rotation of rod 2 with respect to brick 1, but this is not inconvenient if only 4 ring plugs are installed in 1 row bricks alternate, or in bricks of the extreme rows if in the sheet of bricks 10 there is an odd number of rows, or in bricks of the extreme rows if other types are installed at opposite ends of retention means.

In the examples shown in Figs. 21 and 22, the retaining means comprise, at least one side edge of the brick sheet 10, a stop 5 fixed at one end of the rod 2. This stop 5 is larger than the holes 1a of the brick 1, of so that it cannot pass through the corresponding hole 1a and retains the movement in an axial direction of the rod 2 without preventing its free rotation with respect to the brick 1. In the example of Fig. 21, the stop 5a is provided by a washer 35 provided with a hole through which an protruding end of the rod 2 is passed, and said washer 35 is fixed to the rod 2 by an adhesive or weld 36. In the example of Fig. 22, the stop 5a is provided by a retaining washer 37 provided with a hole through which a protruding end of the rod 2 and flexible pins 38 extending into the hole and elastically pressing against the outer surface of the rod 2 is passed. retainer 37 can be installed under pressure without the need for adhesive or solder and provides sufficient retention for a majority of applications.
tion

A piece of rod is shown in Fig. 17 U-shaped bent 39 that defines a pair of rods 2 parallels connected at their ends by a connection element 2a of adequate length at the distance between the two holes 1a or 1b of the bricks 1. Thus the two parallel rods 2 can be used as two of the adjacent rods 2 in the sheet of bricks 10 and the connecting element 2a acts as the means of retention to retain the two rods 2 against movements in an axial direction with respect to one or two bricks 1 on one edge side of the brick sheet 10. In addition, the element of connection 2a, which is arranged in the longitudinal direction, acts as a separating element when this side edge of the brick sheet 10 is placed adjacent to a side edge opposite of another sheet of bricks 10 from which the ends of the corresponding rods 2 do not protrude, for example because they are retained by annular caps 4 as described above in relation to Fig. 20. The rod piece U-shaped bent 39 is applicable to the sheet of bricks 10 according to any one of the simple embodiments or complexes of the present invention.

It will be understood that alternately the two rods 2 and the connecting element 2a can be separate parts joined, for example by adhesive or welding, instead of a single piece of bent rod "U" 39. In Figs. 7, 11 and 15 links 3 are shown adjacent to bricks 1 in one of the side edges of the brick sheet 1. These links exteriors may be attached to protruding ends of the rods 2, for example by adhesive or welding, or by means of ring caps analogous to those described above in relation to Fig. 20 arranged between an outer surface of the rod 2 and an inner surface of the hole 3a of the link 3, so that the outer links 3 act as connecting elements and as retaining means on this side edge of the sheet of bricks 10. In any case the connection elements 2a will be arranged in the longitudinal direction of the brick sheet 10 and joined by its ends to ends of two of the rods 2 adjacent.

In general, the two holes 3a of the links 3 are separated by a certain distance according to the shape and dimensions of the bricks 1 to provide some separation spaces of a desired extension between the bricks 1 of each row. These separation spaces must allow a bending or folding the brick sheet 10 by a turn of 90 degrees or more around any of the rods 2. In Some applications may be convenient for one or both holes 3a of each link 3 be elongated holes in the direction longitudinal link 3 to allow some play in the positions of the rods and the bricks.

In Fig. 18 a link 3 is shown according to a alternative configuration including a single elongated opening that It encompasses the two holes 3a. This link 3 of Fig. 18 can be formed, for example, by a piece of rod conveniently bent and with the ends joined, for example by adhesive or welding 40.

A link 3 according to another is shown in Fig. 19 alternative configuration intended to act additionally as separator element to provide separation spaces relatively wide For this, link 3 comprises a body elongated with two holes 3a separated by a required distance and thickened regions 41 around holes 3a. These Thickened regions 41 have a thickness dimensioned to provide separation spaces of a desired width between the rows of bricks 1, while a portion of connection 42 between said thickened regions 41 has only the thickness required to ensure tensile strength required

In any of the simple embodiments and complexes of the present invention, the bricks 1 can be of a variety of materials, although a ceramic material is preferred, a concrete material, or a stone material. The rods 2 can be of relatively rigid materials, such as steel or other metal alloys, or plastic or synthetic materials optionally reinforced with fibers, or of relatively materials flexible, such as steel cables, nylon cables and the like. The material for links 3 and washers 6 separators, when there are, it will preferably be a metallic material, such as steel or aluminum, or a plastic or synthetic material. For applications in which rods 2 and links 3 are exposed to the weather it is preferred that the material of the rods and links are corrosion resistant, as per example stainless steel, galvanized steel, painted steel, aluminum, or a plastic or synthetic material.

Referring now to Fig. 23, a palletizing method of a flexible brick sheet 10, folding and rolling, according to any one of the embodiments simple and complex of the present invention described above. The method comprises placing a section of said brick sheet 10 on a pallet 8 and fold or zigzag the brick sheet 10 around one or more of the rods 2 to form two or more sections of brick sheet 10 superimposed on said pallet 8. For this, the brick sheet 10 can be supported vertically by lifting means such as, for example, a forklift, a crane, or the like, and said means of lift can be maneuvered first to place an edge bottom of the brick sheet 10 adjacent to a side edge of pallet 8, and then to make a downward movement vertical of the brick sheet 10 in relation to the pallet 8 in combination with horizontal reciprocating movements of the sheet of bricks 10 in relation to pallet 8 of an amplitude selected according to the dimensions of pallet 8 to depositing a first section of said brick sheet 10 on the pallet 8 and successive sections folded in zigzag superimposed on First.

In the example shown in Fig. 23, for fastening the brick sheet 10 to the lifting means is used a loading bar 43 connected to the lifting means (no shown), and hooks 44 attached on one side to said bar of load 43 and hooked by the other to a last rod 2 of the brick sheet 10. In the illustrated example, the sheet of Bricks 10 comprises links 3, and a group of links 3 ends protrude from the end of the brick sheet 10 to support an auxiliary rod 2 that can be installed through the holes 3a free of the final links 3 to effect the handling operations of brick sheet 10 and removal when It is no longer necessary.

Figs. 24, 25 and 26 show sheets of bricks 10 according to different embodiments of the first aspect of the present invention zigzag bent in four overlapping sections and placed on respective pallets 8 according to the method of palletizing the second aspect of the present invention. The blade of bricks of Fig. 24 has the bricks 1 arranged in grid, the brick sheet 10 of Fig. 25 has the bricks 1 arranged to compact breaker, and the brick sheet 10 of Fig. 26 has the bricks 1 ready to break-joint, as has been previously described. 10 palletized brick sheets can be stored in an orderly manner occupying a space relatively small and can be handled comfortably by A forklift.

A person skilled in the art will come up with modifications and variations from the embodiment example shown and described without departing from the scope of the present invention as defined in the appended claims.
