Description

Technical field

The present invention relates essentially to blocks that can be manually disassembled into at least two blocks that can be used to construct structures such as walls or the like.

State of the art

BACKGROUND OF THE INVENTION Bricks for the construction of mortar walls or similar structures are known. For example, PCT International Application No. PCT / CA 96/00348 (International Publication No. WO 96/38636, published December 5, 1996) describes wall building blocks that can be stacked and bonded without bonding material such as mortar. The block has an upper surface with a recessed element and a lower surface which has a notch element. Both elements are formed such that when similar blocks are stacked on top of each other, the lower surface of the block engages with the upper surface of a similar block below, while the upper surface of the block engages with the lower surface of the block above it.

As described in the aforementioned PCT application, blocks can be obtained by mechanically dividing a parent block having a pair of such blocks connected by their upper surfaces, the upper surfaces of which are defined by a split line extending from the upper groove to the lower groove. The disadvantage of the above-mentioned primary unit is that it is mechanically divided by pressing a dividing device having a blade or knife into one of these grooves, thus requiring proper pressure. The mechanical division of similar parent units requires cumbersome mechanisms that are expensive, require special care, and require multiple operators to whom they may be dangerous. Another disadvantage is that the blocks obtained in this way have the front outer surface inevitably having the appearance of a broken stone, which may not always be appropriate.

Other disassembled blocks are also known, which require the use of dividing tools, such as chisels or splitters, to divide into multiple blocks.

It is to be understood herein that the term "manually disassembled" means hand disassembled means, for example, as will be discussed later in the description.

It is to be understood that the expression "manual lever action" means that the members of the block may perform the function of a lever and may even increase the force applied. The block members, for example, may be rotated about a longitudinal axis passing through manually dismountable vertical cross-linking means which act as a pivot point. For example, the respective portion of each block element may be gripped either directly or indirectly, and the force applied to the block elements may also be applied inward, i.e. push corresponding parts of the block elements towards each other and outwards so that they are pushed against each other. The tension created in this way causes tension on the manually breakable means of vertical cross-linking, which overcomes their strength, i.e. the adhesive force at the fracture line and causes the fracture of the manually disassembling vertical cross-linking means and further separation of one block element from another. The parts of each block element to be grasped, for example, may be different, i.e. it is possible to grasp the upper part of the first block element and the lower part of the second block element when the respective parts are pushed towards each other or against each other.

As previously mentioned, manually disassembling vertical cross-linking means may, for example, consist of a manually breakable bridge member that links the block members at a distance from one another. Manual disassembling means of vertical cross-linking may, for example, consist of a manually disassembling coupling member. In this case, the manually disassembling connector can directly connect the members of the block, i.e. to talk to each other directly or to be right next to each other.

It is understood that the manually disassembling vertical cross-links are shaped to facilitate manual separation of the manually disassembled vertical cross-links while being strong or having sufficient adhesive strength to hold the block members together during transport and processing. when the user separates them.

The adhesion of manually disassembled vertical cross-links may vary depending on the material of which the manually disassembled unit is formed. The manually breakable block may be formed of concrete, clay, aggregate or other suitable material, such as a molding material, which may be broken. For example, a manually demolished block can be formed of a concrete mix consisting of 61% sand, 27% aggregate, 8% cement and 2% aggregate.

The grip of a manually disassembled unit is such that its parts do not collapse by breaking the manually disassembling means of vertical cross-linking. The manually disassembled unit may have a symmetrical shape with respect to the midpoint of the longitudinal vertical section of the manually disassembling coupling. In addition, the manually disassembled unit may also have other shapes, such as asymmetrical shapes.

It is to be understood herein that the expression "visible frontal area of the outer surface" refers to the surface of a block element that is typically seen when a structure, such as a wall or similar structure, is constructed using a plurality of such block elements.

It is to be understood herein that the expression "smooth surface" refers to a surface having a form-like appearance. The surface provided by the mold can be smooth, i.e. uniform in appearance, as opposed to the appearance of a broken stone.

The block members obtained in accordance with the present invention may have a visible front outer surface having a smooth surface portion of the front wall which partially or completely covers the front wall region of the block member. In some of the above cases, the smooth surface portion of the front wall obtained by disassembling the manually disassembled unit may have a portion of the rough surface of the front wall. In some cases, the smooth surface of the front wall may be divided by the rough surface of the front wall.

It is to be understood herein that the term "notch" refers to a line or groove on a surface that, when creating a discontinuous surface, localizes the fracture at the disassembly site and allows proper breaking along the fracture line by the notched notches.

The invention will now be described with reference to the drawings, which illustrate exemplary embodiments of the present invention.

Referring now to FIG. 2 and FIG. 3, which shows an example of a manually breakable unit according to the present invention. The manually disassembling unit 21 comprises a first block element 22, a second block element 23, and a manually disassembling vertical cross-linking means 24 connecting the first block element 22 and a second block element 23. This example shows that the manually disassembling vertical cross-link means 24 is a manually breakable bridge member 24 connecting the first and second block members. Since the first and second elements 22, 23 of the block are substantially similar, their elements are denoted by the same numbers.

Each of the first and second block members 22, 23 has a first flat lateral outer surface 25 and a second flat lateral outer surface 26, opposite the first flat lateral outer surface 25. Each of the first and second block elements 22, 23 has an upper outer surface 27 extending along a first flat lateral outer surface 25 to a second flat lateral outer surface 26. The upper outer surface 27 defines a flanged joint 28, a projection 29 and a first intermediate outer surface 30 which connects the flanged joint 28 with the projection 29. The lower outer surface 31, opposite to the upper outer surface 27, extending along the first flat lateral outer surface 25 to the second flat lateral outer surface 26.

The lower outer surface 31 defines a notch connection member 32, a support member 33, and a second intermediate outer surface 34 that connects the notch engagement member 32 and the support member 33.

The visible front outer surface area 35 extends along the first flat lateral outer surface 25 to the second flat lateral outer surface 26. The visible front outer surface area 35 connects the upper outer surface 27 with the projection element 29 and the lower outer surface 31 with the support element 33. The visible outer outer surface the region 35 includes the visible portion 36 of the smooth face of the front wall 36. The example 36 of the manually disassembled block 21 shown here includes the visible portion 36 of the smooth surface of the front wall substantially covering the entire region 35 of the front wall. the front wall region 35 has a smooth surface. The visible front outer surface region 35 is vertically offset and is located lower than the flange member 28 (as well as the visible rear outer surface region 37).

Each of the first and second block members 22, 23 also has a visible posterior exterior surface region 37. The visible posterior exterior surface region 37 extends along the first planar lateral exterior surface 25 to the second planar lateral exterior surface 26. an exterior surface 31 a notch joint 32 and an upper exterior surface 27 a recessed joint member 28. An example of a manually breakable block 21 shown here is formed such that the rear wall regions 37 face each other. Each area of the visible rear outer surface 37 includes a portion 38 of the smooth rear surface of the visible rear wall, which in this example is divided into two parts by a manually breakable bridge member 24, i.e.. upper and lower manually breakable bridge member 24.

The manually breakable bridge member 24 extends along the first flat lateral outer surface 25 to the second flat lateral outer surface 26.

In this way, the manually breakable bridge member 24 can, for example, be shorter or interrupted, i.e. of two or more spaced sections of the bridge member. As can be seen, the manually breakable bridge member 24 connects the visible regions 37 of the rear outer surfaces, i.e. a portion 37 of each visible posterior exterior surface region 37 is considered to be concealed by a manually breakable bridge member 24. The hidden portion becomes visible only when the bridge member 24 is broken as described below.

In the example shown here, the manually breakable bridge member 24 is disposed midway between the groove connector member 32, 23 of each block member and the recessed joint member 28. In addition, the manually breakable bridge member 24 may be positioned anywhere between the grooves of each member 22, 23 connecting member 32 and recessed member 28.

Referring now to FIG. 4, this figure shows an example of a manually disassembled unit 21 illustrated in FIG. 3, an enlarged view of the manually breakable bridge member 24. As can be seen, the manually breakable bridge member 24 has a first notched notch 39a disposed between the manually breakable bridge member 24 and a visible rear wall smooth surface portion 38 adjacent to the recess 28 of the first unit member 22. a first notch 39a between the manually breakable bridge member 24 and the smooth wall portion 38 of the rear wall adjacent the notch joint 32 of the first block member 22. The first and second notched portions 39a, 39b form a pair of opposite notched indentations defining the first breaking line. a third notch 39c disposed between the manually breakable bridge member 24 and the visible rear wall smooth surface portion 38 adjacent to the second block member 23's flush connection member. 28. A fourth notch 39d disposed opposite a third notch 39c between the manually breakable bridge member 24 and the visible rear wall smooth surface portion 38 adjacent the second block member 23's notch connection member 32. The third and fourth notched portions 39c, 39d form a second pair. the indentations 39a, 39b, 39c, 39d extending along the first flat lateral outer surface 25 to the second flat lateral outer surface 26, that is, in the example shown here, the dotted line and letter B in the drawing. along the manually breakable bridge member 24. Although the example shown here is provided with notched notches 39a, 39b, 39c, 39d, the manually disassembled unit 21 may alternatively not have such notched notches.

Now we turn to Figs. 4A, this figure shows the manually breakable bridge member 24 shown in FIG. 4, magnified view. As previously mentioned, the manually breakable bridge member 24 is configured to be manually broken and at the same time strong or bonding enough to hold the first and second block members 22, 23 together during transport and processing of the manually breakable block. 21st

As mentioned earlier, the grip of the manually breakable bridge member 24 may vary depending on the material of which the manually breakable block is formed. Thus, the manually breakable bridge member 24 will have dimensions that will vary with the material used and the material composition. For example, in the case of a manually breakable block formed by a concrete mix consisting of 61% sand, 27% aggregate, 8% cement and 2% aggregates, the dimensions of the manually breakable bridge element 24 may be as below. These dimensions are given with respect to the manually breakable member 24 extending from one flat lateral outer surface to another as shown in the drawing. The dimensions of the manually breakable bridge member may vary if the manually broken bridge member 24 is shorter or interruptible as previously mentioned. It is important to note that these dimensions are given with reference to the example of block 21 having a height of 150 mm marked by an arrow in Fig. P. 3, block element thickness 65 mm, marked by an arrow Q, and 230 mm long, measured between the first and second planar lateral outer surfaces 25.26, The dimensions are given for this example only.

We now return to FIG. 4A, the manually breakable bridge member 24 has a length 5, indicated by an arrow L, which can vary by about 55 mm. The length L can be, for example, 8 mm. The manually breakable bridge member 24 has a thickness; which is measured at the breaking line between the upper surface and the lower surface.

In this example, the manually disassembled unit 21 has two such break lines as shown by the arrows Ta and Tb. The thickness at one of the fracture lines may vary from 4 mm to 25 mm, and preferably 6 mm. The thickness at the first fracture line Ta and the thickness at the second fracture line Tb may be similar as shown here. Further, the thickness at the first fracture line Ta and the thickness at the second fracture line Tb may differ so that the manually breakable bridge member 24 may be manually disassembled at one of the fracture lines; the manually breakable bridge member 24 may be disassembled at the rest of the break line by a handpiece such as a hammer.

The thickness of the manually breakable bridge member 24 between the two break lines, as indicated by the arrow Te, is greater than the thickness of the manually breakable bridge member 24 at the break line if there is more than one break line, or at the break line which is thicker in the case of two fracture lines that differ in thickness. For example, the thickness Te may be 1.4 times greater than Ta or Tb. In this example, for example, the thickness Te may be 12 mm.

The manually breakable bridge member 24 may be of any shape that would allow it to be manually broken. For example, the manually breakable bridge member 24 may have the shape defined by line D. The manually breakable bridge member 24 may also be of the shape defined by the dotted lines E or F.

We now return to FIG. 3, an example of a manually disassembled block shown here may be disassembled in this manner. The first and second block members 22, 23 may be grasped (by hand), for example behind the respective support member 33. The block members 22, 23 may be grasped directly or indirectly. The manual lever action may be applied by pressing the block members 22, 23 directly through the support members 33 toward each other as shown by the arrows 13A. In this case, the block members 22, 23 may operate by leverage and may even increase the applied force. The manual action of the lever raises tension, for example in the notched notch 39a, which overcomes the gripping force of the manually breakable coupling means 24 at the first fracture line. The elements of the block are rotated about a longitudinal axis of the manually disassembling coupling means, which represents the pivot point. The separation of the manually breakable coupling means 24 along the fracture line from the first notch 39a to the second notch 39b occurs by further separating the first block member 22 from the second block member 23 as shown in FIG. 3A.

Alternatively, (hand) force can be used to press the elements of the blocks outward, i.e. in the direction of the arrows 13B so that they are pushed away from each other. The resulting pressure would cause tension in the second notch 39b and result in the separation of the manually breakable bridge member from the second notch 39b along the first break line to the first notch 39a and subsequent separation of the block elements from one another. The gripping parts for each element of the block may be different, i.e. may be the upper part of the first block element and the lower part of the second block element, such that the respective parts are either pushed against or pushed against each other.

We now return to FIG. 3A, the separation of the manually breakable bridge element 24 exposes the rough surface portion 40 on the manually breakable bridge element 24 and the rear wall rough surface portion 41 on the first block element 22 where the manually breakable bridge element 24 was connected. if the bridge element is broken or a part thereof remains attached to one of the block elements, they may be shot down, for example, by a hammer. For example, the user may drop the manually breakable bridge member 24 by striking it in the direction of arrow 14A, causing the manually breakable bridge member 24 to break along the second break line and remove the manually breakable bridge member 24 or its portion from the second block member 23. , as shown in Figs. 3B. Other suitable means are also used which separate the manually disassembling coupling means 24 or parts thereof which are attached to one of the members of the block.

Separation of the manually disassembled unit 21 may result in elements of the type of unit described in the aforementioned PCT International Application, the entire contents of which are incorporated herein by reference.

Now we go to Figs. 5, this figure shows another example of a manually breakable unit 21 according to the present invention having a shape different from that illustrated in FIG. In the example shown in block 2, the manually breakable bridge member 24b is disposed adjacent to the flange member 28 of each block member 22,23 28. The smooth surface portion 38 of each of the rear wall regions 37 is not divided by the manually breakable bridge member 24b. The first and third indentations 39a ', 39c' are disposed between the respective block members 22, 23 manually breakable bridge member 24b and the flange connection 28, while the second and fourth indentations 39b ', 39d' are disposed between the respective block members 22, 23 manually breaking the smooth surface portion of the bridge member 24b and the rear wall

36.

FIG. Fig. 6 shows another example of a manually breakable block 21 according to the present invention, the shape of which differs from the example illustrated above in that the manually breakable bridge element 24c is disposed adjacent to the groove connection element 32 of each block element 22, 23. In the example of block 5, the rear wall surface portion 38 of each rear wall region 37 is not divided by a manually breakable bridge member 24c. The first and third indentations 39a ', 39c' are disposed between respective block members 22, 23 of a manually breakable bridge element 24c and a rear wall smooth surface portion 38, while the second and fourth indentations 39b ', 39d' are disposed between respective block elements 22 , 23 manually breakable bridge member 24c and groove connector member 32.

FIG. 6, an example of a manually disassembled unit 21 can be disassembled in this manner. The first and second block members 22, 23 are gripped (by hand), e.g. Manual lifting action of the lever causes tension, for example, in the first notch 39a, which overcomes the adhesive force at the first break line and causes the manually breakable bridge member 24c to separate along the first break line from the first notch 39a "to the second notch 39b" separating the first block element 22 from the second block element 23 as shown in Figs. 7. A similar result may be obtained by gripping the respective flanged members 28 of each block member 22, 23 and sliding the block members 22, 23 behind their flanged members 28 against each other as shown in Fig. 16B. 6 in the direction indicated.

Now we go to Figs. 7, the separation of the manually breakable bridge element 24c reveals a rough surface portion 40 'on the manually breakable bridge element 24c and the rear wall rough surface portion 41' on the first block element 22 where the manually breakable bridge element 24c is connected. The manually breakable bridge member 24c can then be removed by dropping it as previously described in FIGS. In terms of 3A.

Referring now to FIG. 8, this figure shows the block elements 22, 23 obtained by breaking FIG. 3 shows an example of a manually breakable unit 21. As mentioned, the elements of the block 22,23 after the separation are essentially the same. The orientation of the first block element 22 is turned sideways so that its second flat lateral outer surface 26 now faces the leaf plane. As can be seen, the first block element 22 is disposed above the second block element 23 when stacked. The front wall smooth surface 36 covers the entire front wall region 35 of each block element 22, 23, while their respective rear wall region 37 includes a smooth surface portion 38 divided by a rough surface portion 41.

FIG. 9 and FIG. 10 shows another example of a block according to the present invention.
