The inventive reinforced concrete wall construction system simplifies the technique currently used since it involves a shorter construction time and requires less manpower and machinery. In addition, it is possible to apply the weight of the concrete at the site of the building, thereby enabling light parts to be handled during construction.

Description

MODULAR CONSTRUCTION SYSTEM FOR THE CONSTRUCTION OF REINFORCED CONCRETE WALLS, USING PERDIBLE LIGHT CONCRETE CIMBRA

DESCRIPTION

TECHNICAL FIELD OF THE INVENTION

The present invention relates to a modular construction system for the construction of reinforced concrete walls based on a series of modules, parts and lost formwork of lightweight concrete and methods for installing them, for the creation of reinforced concrete walls .

This system includes modules, pieces or lost formwork to be integrated as part of the reinforced concrete wall, and modules or parts that will be used in the construction process of the wall but will not be part of it.

The reinforced concrete walls resulting from this construction system will be used to be part of a building or structure, since these will be built on the site of the building.

The construction of reinforced concrete walls through this system simplifies the current technique used, requiring less construction time, labor and machinery. It also takes advantage of the possibility of applying the weight of the concrete in the place of construction allowing to handle light pieces during construction.

BACKGROUND OF THE INVENTION

In the international construction standards a reinforced concrete wall is considered when the following characteristics are met: A) Contains reinforcing elements with high tensile strength such as steel. B) It consists of concrete with high compressive strength. The current construction systems that make use of concrete walls are the following:

I. Precast concrete wall: It consists of a prefabricated concrete wall in its entirety that will be transported to the building site and will be added to the construction using specific anchoring techniques for the wall technology. These anchoring systems allow the wall to be joined with the structural element (s) of the building.

II. Cast concrete wall at the place of construction with formwork:

It consists of establishing a mold or formwork of a non-adherent material to the concrete, with which the necessary pre-assembled reinforcement elements will be covered. Subsequently the mold is cast (filled) with concrete. After the concrete has hardened, the molds are removed (unwrapped), leaving the reinforced concrete wall in the building.

III. Cast concrete wall at the building site with fixed molds:

The necessary pre-assembled reinforcement elements are coated with molds that will remain after the concrete is cast (emptied) into said molds. The molds simultaneously form the faces of the wall.

These molds are available in horizontal or vertical versions for installation and only use synthetic materials such as polystyrene and PVC among others. If the synthetic material of the mold is not necessary or required for the appearance of the wall, a coating should be applied to it, using special adhesives for synthetic materials. The molds are generally of a reduced size since they have to withstand the pressure of the fluid concrete that will be cast inside.

IV. Launched concrete wall:

This wall consists of a wire structure that generally covers polystyrene plates. To this wire structure is applied externally a concrete layer that should be adhered to the structure mentioned above on both sides of the wall.

These four ways to build reinforced concrete walls are the only ones currently in existence, from which a great number of techniques and technologies used in the construction of these walls can be seen. The technologies with greater relevance in the development of this patent are those described and legitimate property of their authors as described and protected by the following patents: Patents

THE BEST WAY OR METHOD KNOWN TO EXECUTE

THE INVENTION

For the construction of Reinforced Concrete Walls using the Formwork Modules

Loss of Lightweight concrete from this patent is required to apply the following Construction Methods: A. Installation of the "Base Formwork" to the Support Surface

B. Horizontal Union of lightweight concrete beams

C. Vertical Union of lightweight concrete beams

D. Installation of Reinforcements within the Base Formwork E. 90 ° Union between Lightweight Concrete Beams

F. Cross union between lightweight concrete beams

G. Installation of the "Formwork Cover" of light concrete H. Die cutting of the Lightweight concrete formwork

I. Casting of the Light Concrete Wall-Formwork J. Removal of Dies and Finishing

The description of the necessary procedures in each of the methods

A. Installation of the lightweight concrete formwork Base to the Support Surface

When installing a Lightweight Concrete Base Base to the Support Surface (foundation), the Fixing Squares must be marked and placed in the correct position where they can be adjusted with the selected Frame Posts. The placement of the fixing brackets involves inserting and adjusting the anchor bolts in the foundation concrete as the first step. The "Formwork is placed

Base "on the Support Surface coinciding with the Posts of the Frame with the Fixing Squares and fasten them with the Fixing Screws with Vertical Post.

Both Screws: Anchoring and fixing will be kept slightly loose to allow a precise adjustment of the lightweight concrete formwork to give it its characteristics of inclination, direction and final position. Once the "Base Formwork" of lightweight concrete is properly adjusted, the Fixing Square Screws will be tightened to keep the "Base Formwork" of lightweight concrete Fixed in the required place and position.

B. Horizontal Union of lightweight concrete beams

To install horizontally adjacent lightweight concrete beams, both beams must be fixed to their Support Surface correctly, which will allow the

Adjacent posts of both Cimbras are joined. Ensure the union and Correct any deviation to maintain an alignment using the required Horizontal Mounting Nuts and Bolts.

C. Vertical Union of Lightweight Concrete Slabs In the vertical Cimbras junction it is required that the Lower Formwork include the

Bottom Square of the Vertical Connector adjusted against the Top Angles of the Frame of the Lower "Base Formwork" before said formwork is cast. Once the Bottom Reinforced Concrete Wall has been cast, the Vertical Connection Screws of the Vertical Connector protrude from said wall, which in turn serves to install the upper "Base Formwork" when its Lower Angles of the Frame are pressed against the Upper Angles of the Lower Wall when using the Upper Vertical Connection Square and the Nuts for the Vertical Connection Screws. The "Top Base" must be properly aligned before tightening the nuts that must hold it firmly in the desired position.

D. Installation of Reinforcements within the "Base Formwork"

For the installation of Vertical Reinforcements (rods) within the "Base Formwork", these reinforcements must already come from the lower element, that is, from any type of foundation known to the state of the art; and with the characteristics that for reinforced concrete constructions are already known. The "Base Formwork" shall be placed on said reinforcements so that they remain within the Frame of the "Base Formwork". If it is necessary to continue these Vertical Reinforcements, the specific mechanisms of continuation of Vertical Reinforcements (overlap) should be used as appropriate. These Vertical Reinforcements must exceed the total height of the Lightweight Wall-Mountable Perforated Wall in case a superior joint with another element is required, such as any type of slab known by the state of the art or to continue with the wall.

For the installation of the Horizontal Reinforcements, said reinforcements should be introduced through the Rack Posts of the horizontal "Base Beams" horizontally. If it is necessary to continue these Horizontal Reinforcements, use the specific mechanisms for the type of Horizontal Reinforcements used. E. 90 ° joint between lightweight concrete beams

For the joining of Formwork at an angle of 90 °, it is necessary to follow the following procedures: The "Base Formwork" will be installed on the support surface as indicated in this patent, taking into account the following consideration: Lightweight Concrete Formwork pre-installed in the "Base Slabs" must be placed with the outer face outside of the 90 ° of the Union between Cimbras, in addition the Union Reinforcements must be introduced at 90 ° before installing the second "Base Cimbra" to the support surface. At the end of installing the horizontal reinforcements in each "Base Formwork", the Union Reinforcements should be fixed at 90 ° between the horizontal reinforcements of each Formwork and hugging the vertical reinforcement of the Union at 90 °.

The lightweight concrete cover forms will be installed first those that will rest on the Vertical Support Tabs and fixed to the Frame; to then be pressed with the missing Cover Formwork that will be fixed to its own frame, thus conforming the respective "Lost Concrete Wall-Formwork".

F. T-union between Cimbras

Similar to the Union at 90 ° the Union will be installed in T. Following the procedures of Union at 90 ° between Cimbras with the difference that the Reinforcement

Internal horizontal of the continuous wall of the T will be a single element and the 90 ° Union Reinforcement must be fixed in an intermediate part of it.

G. Cross Union between Cimbras For the union in Cruz de las Cimbras, it will be installed similarly to the Union a

90 ° in two of the unions with the difference that is not required of the Union Reinforcement at 90 ° since both Horizontal Reinforcements are continuous and only intersect at the intersection point of both walls.

H. Installation of the Formwork Lightweight concrete cover Before the installation of the Lightweight Concrete Cover, it should be checked that the following elements are complete: Reinforcements, Installations inside the wall such as Plumbing, Electricity, Heating, among others.

The Lightweight Concrete Cover Form to be installed must completely coincide with the "Base Form" Frame, which will be fixed. You may or may not use the

Horizontal Base Support Tabs of the "Base Formwork" to make the alignment of the Lightweight Concrete Cap with the Frame easier. Once the Lightweight Concrete Cap Form is properly aligned, it must be fixed to the

Frame using a fixing mechanism such as screws, nails, rivets or any other that apply.

Stamping of the Cimbras

Die cutting of lightweight concrete formwork should be done before casting the wall. To do this, each of the lightweight concrete formwork on the wall (Base Formwork and Cover Form) must be drilled at the same height in order to introduce the Moflo

Recoverable within the Wall-Loss of Lightweight Concrete. The coated part of the Recoverable Bow must be on the inside of the wall and protrude the part of the Bun with thread. The Dies should be fixed horizontally on the Lightweight Wall-Mounted Lost Formwork on both sides, using the Bows as a guide and support. The Nuts for the Bows will have to adjust to the Dies against the Wall-Loss of Light Concrete.

Cutting of the Formwork for Wall in Colindancia

As a special case in the walls of Colindancia where there is no space to be able to install the Dies and Fix them with the Nuts for the Bows, the following should be done: The "Base Formwork" must be perforated with the Recoverable Bows installed with the Nuts for Die Colindancia screwed before the installation of the "Cmbra Base" itself. Before assembling the Lightweight Concrete Lost Wall. The Top Form must have the necessary perforations so that the Bows can cross it. Once the Wall-Mounted Lightweight Concrete Formwork is assembled, the Colindancia Dies must be glided horizontally, securing the Nuts inside their cavity. Colindancia die previously installed. Once the die has been placed, the Recoverable Bun must be turned until the Colindancia Nut for Nut can be adjusted to the Colindancia Die against the wall. The die on the inner side of the wall can be installed as mentioned above.

J. Casting of the Wall-Loss of Lightweight Concrete

The prepared concrete will be poured between both Lightweight concrete slabs ("Base Slab" and Top Slab) filling the cavity formed within the Light Concrete Slab Wall, thereby drowning the horizontal and vertical internal reinforcements (rods) as well as the posts of the Frame one by one. If required, use of known techniques should be made so that the concrete flows easily filling each cavity completely as is the use of vibrators or more fluid concrete.

The concrete that will be poured into the Lightweight Concrete Wall-Losing Wall can have different characteristics that it will inherit from the built wall such as: traditional concrete, high strength concrete, light concrete, concrete with thermal insulation, concrete with acoustic insulation, among others .

K. Removal of Dies and Finishing Once the wall has been cast, it is necessary to wait for the concrete to solidify sufficiently (set). With solid concrete, it is safe to remove the Dies by removing the Nuts for Dies (or by turning the Bows in reverse to release the Nuts for Colindancia Die and simultaneously the Colindancia Die).

When the wall is free of Dies, the Bows must be removed. The Coverings for Removable Bows will remain inside the wall.

To finish the wall, the joints of the lightweight concrete formwork, which now form the wall, must be repaired (filled) on both sides. In the same way, all the holes of the Bows and those obtained thanks to the fastening mechanisms of the Lightweight Lost Beads against the frame (screws, nails, rivets, ...) must be repaired.
