Description

Modular shuttering element for building wall

In the building industry, the structure of walls using modular shuttering elements is well known. Conventionally, these elements comprise two panels connected by spacers or cross members, thereby successively forming two partition walls that can be laminated and cast a setting material such as concrete therebetween. The panel then acts as a shutter for clean concrete.

Thus, the modular element makes it possible to build walls without the use of formwork elements, such as concrete sheetings, which are often used to form concrete walls.

In addition, an arrangement can be made for the panel of the modular element that is sufficiently good in surface so that it does not need to cover the modular element, and can also lower the price.

It has been found from all the prior art that the walls formed using the modular shuttering element show systematically water and air protection defects due to the bridge effect inevitably created by spacers or cross members. This effect allows air and water to pass through the walls by closely adhering to the cross sections and sides of the spacers.

Inevitably, the cast concrete is reduced in all interior surfaces of the modular element, in particular in cross-sections and sides of the spacer. This reduction in concrete leaves an empty space between the concrete and the cross sections and sides of each spacer. This empty space is not able to continuously contact, thereby forming a bridge between panels by itself. In addition, people can see sunlight through walls formed of modular shuttering elements if they systematically close their eyes on each of the modular elements.

The present invention relates to a modular shuttering element for use in building walls.

1 is a perspective view of a standard modular shuttering element according to the present invention; And

Figure 2 is a laminated side view of two standard modular elements filled with concrete according to the present invention (concrete is shown only in the area for understanding the present invention).

It is an object of the present invention to provide a modular shuttering element that makes it possible to provide a wall that is completely impermeable to water and air.

This object, as well as other objects which will become more apparent from the following, is a modular shuttering element for forming a part of a wall which is filled with a material such as concrete and comprises two panels connected by at least one spacer or cross member. And a noble shape, the spacer having at least one deep groove extending over the entire width of the cross section and / or the total height of each side to form an air and water barrier in the material. At least a pair of grooves extending over.

According to another feature of the invention:

The groove is located above the middle and / or side of the cross section of the spacer,

The groove has a substantially rectangular cross section,

The upper surface of the spacer is concave so as to enter the strength member, such as the material and the iron reinforcing member,

Each panel comprises a longitudinal projection at the top of the panel and a longitudinal land at the top thereof, and at the bottom a longitudinal channel and a longitudinal bottom land arranged in an arrangement to secure each other,

When longitudinal protrusions, channels and lands are formed and fitted together, a clearance exists to avoid penetration of water by capillary action,

The longitudinal protrusions and the channel move from the outside in the inner direction of the element and comprise at least one flank, a horizontal flank and a vertical flank inclined with respect to the vertical;

Each panel comprises at least one passage extending between its top and bottom surfaces, whereby the permeable water is drained vertically,

Each panel extends over the entire length of its top and includes a groove connected to the passage to guide water that can penetrate the passage;

The surfaces of the panel designed to mate with adjacent members are shaped to mate with each other,

The side surface is formed so that the mat provides a gap to prevent water from penetrating by capillary action.

The invention also provides a wall composed of a modular shuttering element as described above and filled with a material such as concrete.

Thanks to this property, when a material such as concrete is poured into a wall formed of the modular element according to the invention, the latter is stored in grooves or rebates formed on the cross sections and sides of the spacer, thereby preventing the concrete from shrinking. Effective air and water barriers are formed.

Other features and advantages of the present invention will become more apparent from the description of the accompanying drawings.

In these figures, like reference numerals refer to parts or assemblies of parts that function the same or similar.

Referring now to FIG. 1, a standard modular shuttering element S according to the present invention can be seen, where “standard” is the “specific” modular shuttering element required to form angles, anchorages, door and window openings, and the like. As opposed to, it refers to a modular shuttering element that is placed on the general part of the wall.

Although not described, the invention clearly addresses certain modular shuttering elements.

The standard modular shuttering element S may be substantially parallelepiped shape or upside down. In other words, it is symmetric about an axis Z-Z 'penetrating its center of gravity, thereby designing this axis to be located vertically (see FIG. 1).

This modular shuttering element comprises two panels 1, 1 ′ connected together by spacers or cross members 2, 2 ′.

According to one basic feature of the invention, each spacer is at least one deep groove or rebate 3, 3 'and / or the entirety of each one of its sides extending over the entire width of its cross-section midsection. At least a pair of grooves or rebates 4a, 4b, 4a ', 4b' extending over height. However, without limited characteristics, these grooves or rebates 3, 3 ', 4a, 4b, 4a', 4b 'have a rectangular cross section as shown in FIG.

The other sides of the spacer will be hollow 5, 5 ', which can be rounded or have a different shape as shown.

Each panel 1, 1 ′ comprises, in its upper part, longitudinal projections 8a, 8a ′ and upper longitudinal lands 9a, 9a ′, at its lower part, longitudinal channels 8b, 8b ′ and mating with each other. The lower lands 9b and 9b 'which form an arrangement are included.

Each longitudinal protrusion moving inward from the outside of the modular shuttering element includes edges 10a, 10a ', horizontal flanks 11a, 11a', and vertical flanks 12a, 12a 'that are inclined relative to the vertical line.

The inclined flanks 10a, 10a 'are preferably made at an angle of about 30 ° with the vertical line.

The longitudinal protrusions 8a, 8a ′ engage the outer surfaces of panels 1, 1 ′ via any chamfer 15, 15 ′ formed in the upper horizontal end of the modular shuttering element.

Optional chamfers 15, 15 'are preferably made at about 45 degrees with respect to the vertical line.

Each longitudinal channel 8b, 8b 'moving the modular shuttering element from the outside into the interior comprises flanks 10b, 10b', horizontal flanks 11d, 11d ', and vertical flanks 12b, 12b' inclined with respect to the vertical line.

These longitudinal channels engage the outer surfaces of panels 1 and 1 'via horizontal flanks 16 and 16' which lie in the same plane as the lower longitudinal lands 9b and 9b '.

The upper and lower portions of panels 1, 1 'are preferably placed so that the upper longitudinal lands 9a, 9a' and the lower longitudinal lands 9b, 9b 'of the elements lie opposite each other when the two modular shuttering elements are stacked on each other, While the longitudinal projections 8a, 8a 'and channels 8b, 8b' are separated by gap J and the preferred gap is at least 2 mm (see Figure 2).

Panels 1, 1 ′ comprise grooves 17, 17 ′ on the lines of the vertical flanks of longitudinal protrusions 8a, 8a ′ extending over the entire length of the top of the panel, respectively.

The cumulative transverse extension El and the adjacent grooves 17, 17 'of the longitudinal protrusions 8a, 8a' are substantially the same as the transverse extensions of the longitudinal channels 8b, 8b '.

In addition, each panel 1, 1 ′ comprises at least one passage 18, 18 ′ extending between the top and bottom surfaces of the panel and connecting with the grooves 17, 17 ′.

The sides 20, 20 'of the modular shuttering element S, which are designed to coincide with the adjacent modular shuttering elements, also preferably have a paired shape.

Like the top and bottom of the panel, when one of the two modular elements is fitted into the other, certain parts 21a, 21b of these sides are adjacent to each other adjacent to each other, while the other parts 22a, 22b of these sides are at least 2 mm long. It is preferably formed to be separated by a gap (not shown).

The aforementioned modular elements can be made by vibration molding using all kinds of everyday materials used in the construction field. It is desirable to use waterproof concrete that meets architectural grades (ie, meets certain beauty standards such as color, texture, etc.).

Practical tools and advantages of the modular shuttering element according to the invention will be apparent from the above description.

In the following, it will be described in more detail with respect to Figure 2 of the accompanying drawings.

The first step, to provide a wall, consists of placing the first row R1 of the modular shuttering element over a completely horizontal ground obtained, for example including a concrete platform (not shown).

The modular shuttering elements fit together into one another using mating shapes on the sides.

Standard modular shuttering elements are for straight line sections, left or right hand angled modular shuttering elements are for corners, and frame end and half frame stage modular shutters Ring elements are used for door and window openings.

If the first row R1 of the modular shuttering elements is installed, the second layer R2 of the modular shuttering elements can be placed in a vertical stack, that is to say at a horizontal offset between the two rows, or deviated from each other ie It may be arranged to be horizontally offset by adjacent rows up to half the length of one modular shuttering element.

The derivation and precise positioning of the modular shuttering elements of the second row described above is ensured by the longitudinal channels 8b, 8b 'interacting with the longitudinal projections 8a, 8a' of the modular shuttering elements of the first row R1. .

The vertical loads are only transmitted between the lands 9a, 9a 'in the upper longitudinal direction and the lands 9b, 9b' in the lower longitudinal direction due to the aforementioned geometrical features. Under the above-mentioned conditions, the above-mentioned lands must be completely flat (see below) to avoid the risk of cracks forming in the preliminary stage before the concrete is poured and the walls of the general shape (see below).

To erect walls, the fitting and laminating operations are repeated as necessary.

During the above operation, horizontal strength members such as metal reinforcing bars 30 are placed in the channels formed by the upper concave surface 5 of the spacer or cross member 2 at regular horizontal intervals.

Stacking the above-described rows of modular shuttering elements in a straight line or at an angle includes the effect of causing their spacers to align vertically. In this way, vertical strength members such as metal reinforcing members (not shown) may be disposed at regular vertical intervals between the panels.

When the wall has reached a certain height, a material such as concrete 40 is poured between the panels to completely fill the space between panels 1, 1 'and thereby constitute the wall structure.

In particular, concrete 40 fills the recess formed by the top surfaces of spacers 2 and 2 ', and the grooves 3, 3', 4a, 4b, 4a ', 4b' formed in the cross-section and side of the spacer, thereby paralleling the wall surface. Form a seam 41 that extends smoothly.

The seam 41 described above solves the problems of air-tightness and water-tightness of the prior art modular shuttering elements. That is, the seam forms a sealing barrier that prevents air and water from penetrating by capillary action on the cross-sections and sides of the spacers 2, 2 ', whereby it is effectively retained despite the slump or shrinkage of the concrete 40. This eliminates the bridge effect of the prior art.

In addition, the amount of water that can reach the seams described above is greatly reduced by the geometry of the top, bottom and side portions of panels 1, 1 'and the channels 17, 17' and passages 18, 18 'formed in the panel.

Indeed, the engagement of longitudinal projections 8a, 8a 'and channels 8b, 8b' on one side in pairs and the side parts in pairs on the other is a dynamic penetration of water, ie wind This results in the formation of a mechanical barrier that prevents penetration by the movement of water, such as rain on the wall.

In addition, the gap between the longitudinal projections 8a, 8a 'and channels 8b, 8b' provides a separation area between the modular shuttering elements where water hardly enters by capillary action. These physical barriers are formed, so to speak, to prevent the ingress of water. Passages 18, 18 ′ formed in the vertically aligned panels 1, 1 ′ allow for recovery of water that has only reached channels 17, 17 ′ formed in the upper portion of the panel, which leads to the bottom of the wall.

Similarly, the gap between the sides 20, 20 'of the modular shuttering element acts to prevent the penetration of water by capillary action.

In addition, the modular shuttering element of the present invention is formed to be at least visible from the outside. Therefore, the above-mentioned factor which contributed to aesthetic quality is the first.

An optional horizontal chamfer 15 'can highlight adjacent lines between the modular shuttering elements and thus create a visual shape of the constructed wall.

Concrete that satisfies the architectural grade can be used to form the exterior of the wall according to the architectural requirements of the site in which the consumer wishes to build.

Apparently, the present invention is not limited to the above-described embodiments, and the above-described embodiments are provided as non-limiting examples.

As mentioned above, for example, the bottom surface of the spacer of the modular shuttering element of the present invention may comprise a plurality of grooves.

For example, the modular shuttering elements of the present invention may be used to erect curved walls.

In addition, the wall composed of the modular shuttering element according to the invention can be filled with a material having thermal and / or acoustical insulation properties, such as lightweight concrete, ie concrete including synthetic aggregates.
