The features with modules of the present invention render the structure durable, easy to maintain, hurricane- and earthquake-resistant, fireproof, termite-proof and able to withstand inclement weather, unbreakable and therefore not susceptible to cracking or splitting, all the aforesaid because all the walls are constituted from reinforced concrete, namely the walls thereof are structural walls.

Description

PRISMATIC CONSTRUCTIVE SYSTEM

Field of the Invention

[001] This invention relates to the field of construction. More particularly, it discloses a module of lightweight thermoplastic polymeric material, being modular for wall construction.

[002] The present invention describes a Prismatic Building System consisting of plug-in modules formed by building blocks made of thermoplastic material, preferably PVC, of the male-female type, internally filled with concrete or similar material.

The modules always fit vertically and horizontally in the work, composing walls with diverse geometries elaborated in the architecture for the later concreting. It is an industrialized process, organized in stages, comprising the following steps: injection of parts into molds to obtain the modules, fitting of the modules for wall mounting without the need for complementary services such as laying, plastering, plastering, plastering, etc. the internal concreting of the modules to make the building structurally rigid, with the internal filling of the modules being preferably made with self-compacting concrete.

[004] All building installations should be inserted internally into the modules through pre-existing vertical and horizontal ducts to be installed by construction professionals. [005] Modules can be produced in the desired color and textured for final application on site without the need for any final finish on the internal and external areas of the building.

[006] The module formulation is designed specifically for the application, with its ultraviolet protection as its main focus. Since PVC is an intrinsically self-extinguishing resin, it does not require flame retardant additives. Since PVC resin is totally non-toxic and inert, the choice of additives with these same characteristics allows the manufacture of various products, including: films, seals and laminates for packaging, toys and medical accessories such as hoses for serology and catheters. Mixing PVC resin with additives is known as PVC compound or vinyl compound, and depending on the substances added and their quantities, it is possible to shape PVC articles that look completely rigid (such as a drinking water pipe) or still as flexible and squishy as a garden hose. The polymer, derived from chlorine, contains a high content of chlorine - almost 60% by weight - which is why it has a low flammability index and a high flame extinction rate in the combustion process.

[007] Removed the source of the flame, the fire ceases immediately. Rigid PVC (such as profiled) formulations, in particular, are very resistant to ignition and flame propagation. Since vinyl is made up primarily of ethylene and chlorine, this gives vinyl two advantages: it is not as susceptible to price changes in the oil market and is not a good fuel like petroleum derivatives. Another advantage of PVC in a fire environment is that the polymer has less carbon in the chain, which means less carbon dioxide emission. The PVC structure resists impact, is not attacked by lime or cement and has high chemical resistance. Modules made of PVC blocks have other advantages such as thermal and acoustic comfort, other intrinsic properties of the resin, and reinforce the fact that they accelerate construction and reduce waste. It is possible to streamline the construction site and reduce construction material losses to almost zero. In addition, it is possible to build a building in the Prismatic Building System with the perspective of reducing the time by one third (1/3), considering the conventional construction.

[008] Modules made of PVC material are molded by plastic injection in a factory unit and transported to the site for its final use. Already at the construction site, the walls are assembled by the socket system, ready to receive concrete and the installations.

[009] Modular construction enables the construction of high quality, low cost solid structures.

[010] The modules are lightweight and stackable, substantially lowering the cost of transportation.

[01 1] The invention relates exclusively to construction, and its main objective is to make a work dynamic and easy to perform, allowing the walls to have various functions, among them the most essential is the ability to resist structural loads. of buildings.

[012] The invention is intended, inter alia, to improve the thermal properties of buildings by the presence of the module blanks, object of this invention. The heat that strikes a building is carried by the outer ducts to the highest point and vertically the heat through the spans from the exterior walls of buildings to their highest point, preventing the passage of heating to the indoor environments. All modules contain internal vertical ducts, which fit and align with the modules inserted below, so that when said duct is combined with the corresponding duct of a neighboring block, a single vertical cavity forms. This fitting combination forms the alignment of the pipelines for sewage and stormwater piping installations without the need to insert extra pipes.

[013] Construction with the modules is simple and a building can be erected without the need for skilled labor. Unskilled workers can easily adapt to prismatic construction with minimal supervision. Door and window openings are easily located due to the accuracy of the building system.

[014] Buildings will not require the steps common to conventional construction, such as laying, splintering, plastering, plastering, and fine lime, because as the finish requires, their walls will be ready to receive internal or external painting or to perform the placement of wallpaper internally, allowing for quick work on site.

[015] The modular features of the present invention make the construction durable, easy to maintain, hurricane and earthquake resistant, fireproof, termite and weatherproof, unmistakable and therefore not cracked and cracked, all because All walls are made of reinforced concrete, ie their walls are structural.

State of the art [016] In conventional construction, for the lifting of the walls are used ceramic blocks, known as bricks, made in industrial form using burnt clay. According to the historical model form, rustic bricks are manufactured in industrial production by the automatic insertion of clay into molds.

[017] Also according to the foregoing, concrete blocks and their various geometries are also known for the construction of buildings. Walls constructed from concrete blocks can perform the functions of closing only the walls or also perform the structural function by eliminating columns and beams and reducing the use of reinforcement and formwork.

[018] Because of their construction, bricks require the use of kilns that demand a large amount of energy from burning coal for several days, producing a surplus of environmental pollution and consequently clearing the forests. The material of these blocks is brittle and in particular also has significant disadvantages in the presence of water or moisture. Concrete blocks are rectangular shaped masonry units and are mostly made up of two vertical chambers. One of the main difficulties in creating cement block walls is that measurements and adjustments must be made as the construction process is carried out.

[019] Bonding material should be laboriously applied between each new block and all adjacent blocks to avoid grout wastage.

[020] Conventional constructions require skilled labor in order to obtain a work with regular plumb and square walls. Therefore Conventional building processes are time consuming as well as subject to significant human error.

Summary of the Invention

[045] The object of the present invention is to describe a practical, fast and easy building system consisting of plug-in modules made of hollow modules of lightweight thermoplastic polymeric material for modular construction.

[046] The present invention furthermore aims to improve a modular system for civil construction in particular; cost-effective and resource-efficient production and the longevity of building blocks.

[047] Parts are adapted to be produced separately, ie the entire module, the half module and the corner module, using industrially made injection molding machines in manufacturing units.

[048] The prismatic building system can be produced from recycled thermoplastic polymeric material.

[049] When buildings receive the application of the prismatic building system, development is achieved by joining a plurality of thermoplastic modules, preferably made of PVC material, intertwined between them, providing for mutual attachment to the top and sides of the module, through two notches on its base and four notches on its ends, allowing the perfect connection between all modules.

Said lower and lateral fittings allow the longitudinal and vertical connections of the walls. The pieces are joined longitudinally by the notches of the external projections present at their arrow-shaped corners, which will align with the notches of the following pieces. Also, to allow vertical alignment, lower projections fit into the ducts of the parts below, allowing individual modules to be inserted one above the other in a simple and repetitive manner.

[051] After the modules are laid on site, all horizontal and vertical ducts interact, ie in prismatic buildings allow vertical installations to communicate with horizontal installations anywhere on the wall. Vertically will pass all possible pressurized or non-pressurized building installations. Horizontally, any installation other than sewers and rainwater, which runs without vertically, may pass through.

[052] These facilities are common to all buildings: electrical, communication such as telephone, intercom and logic, plumbing, sewage, rainwater, heating and cooling ducts, gas network, air conditioning, among others.

These prismatic modules may have incorporated many utilities far beyond those described herein, making the system an intelligent construction method by its diversity of options and possibilities.

Detailed Description of the Invention

[055] In the present invention the injected modules have the preferred dimensions of 20 cm wide x 20 cm long and 15 cm high. [056] The inner part of the modules is divided into at least two vertical ducts (Fig. 4 / D and Fig. 4 / F), prism-shaped, because of their angles to the outer face, which will serve as ducts. communication of building installations.

[057] In the center of the module there is a closed area (Fig. 4 / E), which accumulates three functions:

• Module rigidity;

• Communication on both sides of the walls;

• Duct connection (Figs. 6 / A, 7 / A and 8 / A) running the length of the wall horizontally.

[058] Prismatic modules are divided into three basic models: wall module (Figs. 1 to 5), corner modules (Figs. 10, 1 1 and 12) and door and window module, also called half-module. (Fig. 9). Its fittings are divided into two types:

[059] Vertical Plug-in System: This plug-in system is located at its base, male and female, which allows the modules to be vertically aligned and enables the vertical ducts of building installations. The locking pins are located diagonally equidistant at the bottom of the modules (Fig. 1 / A and Fig. 1 / F) for easy stacking purposes.

[060] Horizontal Fitting System: Fits are located on the four edges of the modules, also male and female, but the fits have the similarity of arrows with rounded corners. The ends of the modules have female-type fittings (Fig. 1 / C and Fig. 1 / H) and male-type fittings (Fig. 1 / B and Fig. 1 / E) enabling longitudinal interconnection between them. [061] These fittings allow locking and horizontal alignment, not allowing the walls to rupture longitudinally, when casting concrete, and the parts are independent of the direction of placement of the pieces, facilitating the execution of wall assembly.

[062] After all the walls are assembled and their predefined height, the structure is locked vertically with the aid of fasteners or fastening strips, determining the perfect alignment and plumb of the building before its concreting. The efficiency of the work will be determined by placing these wall fasteners close to the floor.

[063] During the assembly of the modules, the vertical and horizontal rebar will be placed, which establishes the double reinforcement in the central area of the modules and will define the reinforced structure of the building.

[064] After mounting the prismatic modules, placing the double steel reinforcement (rebar) and distributing the ducts horizontally, ie along the walls, each floor is then concreted.

[065] Modular construction enables the rational use of concrete, allowing the creation of structural conditions for the building, as well as enabling the full communication of installations by existing ducts or ducts inserted horizontally into the modules, thus making a viable and economical system of construction.

[066] According to the functional aspects of intercommunication of building installations, they are divided into:

VERTICAL FACILITIES: [067] Pressurized installations: These are pressurized installations: hydraulic network, GN / LPG network, fire system, among others. These installations will use existing prismatic module ducts to pass specific pipelines.

[068] Non-pressurized installations: non-pressurized installations using gravity for their displacement: sewage and rainwater, and other installations such as the electrical and communications system (tv, internet, telephone and intercom). These networks will directly use the prismatic module ducts, ie without the addition of any other type of piping.

[069] For individual pressurized or non-pressurized installations, building ducts will be used exclusively within each apartment from the building plumbs.

HORIZONTAL INSTALLATIONS:

[070] Perpendicular installation: The perpendicular or lateral horizontal installation, already present in the module, is located in the central hub (Fig. 4 / E), allowing communication from both sides of the walls. Because this cube is closed in its upper part, not allowing the entrance of concrete inside, which makes communicable both ducts of the same block, consequently both sides of the walls.

[071] Longitudinal installation: allows horizontal communication within the walls in the longitudinal direction, that is, in their extension. For this to happen, ducts must be inserted connecting module by module. In your By design, this is an installation that requires the placement of internal pipes to allow full integration and communication within the walls.

[072] All construction works are subject to the possibility that their steel reinforcement could be affected by pollution from cities, industrial areas and beach seas. This occurrence causes the armatures to oxidize causing partial ruin of the metallic structure of the buildings, requiring recovery with high cost. In the prismatic system, the buildings are protected from pollution and weather, because their entire structure is surrounded by the thermoplastic polymeric material of the modules, isolating the concrete and its reinforcement from the external environment.

[073] Buildings, after the end of their useful life, allow the thermoplastic polymeric material to be reused, that is, to allow its recycling, since the material does not pose a risk to health or the environment.

Multifunction Prismatic Building System

[074] The System, object of the present invention, consists basically of a multifunction building module, to be used in civil construction for various applications, described below:

[075] Constructive physical model - serve as a model for any type of building architecture, barracks, schools, factories, among others, with the use of concrete, whose cure will be definitive, or temporary, with the use of sand inside; [076] Facility ducts - module prisms have the function of internal ducts of basic building installations such as: sewage, rainwater, electrical, LPG, communications, etc;

[077] Ventilation and air conditioning - Internal ducts may be used as a route for forced ventilation or air conditioning;

[078] Vacuum Mail - Internal ducts can be used as vacuum mail for transporting documents, magazines, among others, using vacuum;

[080] Air Filtration - Internal ducts may be fitted with a filter system and insufflation pump to filter indoor environments by filtered air insufflation that will allow the air to be cleaned and polluted before being injected into the rooms.

[081] Indoor lighting - ducts can be turned into lighting areas by extracting their sides, by attaching translucent plates and LED strips to provide room illumination;

[082] Exterior lighting - the exterior walls of modules can also receive LED strips and translucent plates, presenting a decorative external effect to buildings;

[083] Thermal comfort - due to its characteristic of vertical communication, it is possible to reduce the internal heating of buildings from the solar rays, keeping the upper and lower ducts of the outer walls open, allowing the natural wind to pass through; Other constructive applications

[085] Military Camp - use the SCP to build a military camp, where temporary buildings can be erected and dismantled as quickly as possible using compacted sand inside;

[086] Soil and Moisture Containment - Because the modules are made of lightweight, therefore waterproof, thermoplastic polymeric material, they can be used for subsurface containment without any other waterproofing method normally used in construction;

[087] Various formats - The fact that prismatic modules are manufactured by injecting thermoplastic material allows for numerous variations of module models to fulfill a wide range of functions, as long as they preserve the system of lower fittings and their ends. Different formats may incorporate different technologies to meet the needs of the residents of the buildings.
