Abstract

This application describes a robust system consisting of a wide variety of planar plates, preferably made of polypropylene, which are reusable, interconnectable and interchangeable and can be used for building forms in the construction industry. The parts have equidistant side openings at half-height and a fastening element that are capable of significantly increasing the modularity of the system. In addition, said parts have ribs at right angles to one another so that the whole provides the necessary inertia without increasing the weight of the system. Angles on the sides help prevent concrete run-off, and openings called relief cavities facilitate the maintenance and cleaning of the parts.

Description

SYSTEM OF CONNECTORS AND REUSABLE MODULAR PLATES, FOR CONSTRUCTION OF SHAPES IN CIVIL CONSTRUCTION

FIELD OF ACTIVITY

[001] This utility model is aimed at the civil construction area, more specifically for the construction forms sector for buildings.

STATE OF THE TECHNIQUE

[002] The system of plastic plates, reusable for building forms in civil construction, due to its simplicity can generate benefits for both the large institutional builder and the small master builder or family man who, with difficulty, builds his own house, adding a valuable reduction in final construction costs, due to the savings resulting from the replacement of 80% of wood costs and labor costs linked to the various tasks typical of using wood, through the use of reusable plastic materials, which can be rented in construction materials warehouses and transported and assembled by the interested party, with significant savings in labor and logistics.

[003] Patent application BR 102017001259-0 describes a system of connectors and reusable flat plastic plates composed of just two plastic plates with preferred dimensions of 60x60x7 cm, said connectors being in cylindrical shape with through holes for said connectors. The present utility model can be described as a profound improvement of such an application, with a substantial increase in the complexity of the system and the creation of more boards, the said system expresses significant advances that can be summarized in view of the following characteristics: [004] The interconnection openings between the plates (1) are equidistant and located at the mid-height of the parts, so that new modular configurations are achieved.

[005] Furthermore, the pieces have small angles on their sides, in order to guarantee a superior seal, which helps to prevent concrete from flowing between the plates.

[006] The side openings have a relief cavity (6), which in this application has the advantage of being hollow so that maintenance and cleaning of the part are facilitated.

[007] Plates A, J and L have structures in the quadrants with French hands (7) that increase the flexural resistance of the plates and contribute to improving the finish of the molded slab.

[008] Plates B, C, D and E have specific space for housing a strut head of up to 10cm

[009] Plates D, E and L have holes (10) in predetermined positions that are used to pass anchor bars. These bars are responsible for distributing the effort used and reducing the deformation of the external locking element.

[0010] Plates E and F have a recess of around 18 mm that enable additional material support for situations in which the total size of the slab is not a multiple of the size of the parts of the construction system.

[0011] Plates G and F are completely new and have, in addition to their side openings, clamp-type structures (11) that serve to fix the plates.

[0012] Furthermore, the locking system had its levers reinforced and the shape of the end where the levers are positioned was changed to a hexagonal shape, both internally and externally, in order to allow the use of an auxiliary tool for removal. of the board connector.

[0013] The present utility model accumulates the following advantages: [0014] Reduction in the amount of wood on site: Generates savings as it reduces carpentry labor, reduces spending on material disposal, reduces costs by reducing the number of nails;

[0015] Other factors for cost reduction: Reduction in coating costs as the molded structure is more uniform, reduction in electricity expenditure as, due to the (white) and translucent color of the larger 60x60x7 plate, there is the possibility of reduction of lamps;

• Parts are lighter than metal or wooden plates;

• Enable more reuse;

• Material inert with water;

• Reduction in assembly and demolding time;

• Ergonomics and work safety when assembling and unmolding;

• Environmental preservation due to the reduction of up to 80% of wood in the construction of formwork;

• Greater organization of the construction site.

DESCRIPTION OF THE INVENTION

[0016] Unlike the previous technique, the construction system is composed of 12 (twelve) main components:

• PLATE A: with proportions of - 60x60x7;

• PLATE B: with proportions of - 60x15x7 without holes;

• PLATE C: with proportions of - 60x15x5.2 without holes;

• PLATE D: with proportions of - 60x15x7 with holes;

• PLATE E: with proportions of - 60x15x5.2 with holes;

• PLATE F: with proportions of - 60x5x5.2;

• PLATE G: with proportions of - 60x5x7;

• PLATE H: external corner

• PLATE I: inner corner • PLATE J: with proportions of - 120x60x7 without holes;

• PLATE L: with proportions of - 120x60x7 with holes.

• Plate Lock.

[0017] The plates can be briefly described as plastic parts, preferably manufactured in polypropylene, but it is possible to make them with other plastic materials. The choice for propylene is explained by the ease of finding it on the Brazilian market and the impact on the cost of the system, which is a crucial factor for the use of this type of product in civil construction, since one of the objectives is to allow the rationalization of resources and savings in construction, which allows a reduction in the total cost of the work and a more affordable price for the end consumer, thus fulfilling its social function.

[0018] The parts have openings on the sides (1) that allow interconnection between the plates using a fixing element (plate lock), as they are equidistant from each other (2) and are located at the mid-height of the parts, ( 3) the holes allow greater modularization when assembling the set.

[0019] The parts have ribs that are orthogonal to each other (4), with different heights so that together they provide the necessary inertia without making the parts too heavy, which would harm the ergonomics of the system.

[0020] They have angles (5) on their sides to guarantee the meeting at the top of the plate and excellent sealing to prevent concrete flow between said plates.

[0021] The openings on the sides have a relief cavity (6) that are hollow to facilitate the maintenance process, since, being hollow, the removal of dirt is facilitated.

[0022] Specific characteristics of each of the system components:

Plate A; L plate; J board: [0023] They have structures in the quadrants with French hands (7) that increase the flexural resistance of the plate and consequently improve the finish of the molded slab.

[0024] The structure is dimensioned with measures that allow the accommodation of a prop head of up to 16 cm x 16 cm (8) which facilitates the process of deformation and placement of remaining props, contributing to increasing the productivity of the work, a since the remaining struts can be positioned before deforming the system.

Plate B; plate C; plate D; E plate

[0025] They have enough space to accommodate a strut head measuring up to 10 cm x 10 cm (9), which facilitates the deformation process and the placement of remaining struts, contributing to increasing the productivity of the work, since the remaining struts can be positioned before deforming the system.

Plate D; E plate; L plate

[0026] They have holes (10) in predetermined positions that are used to pass anchor bars. They are used in the molding of beams and pillars. As the thrust in the execution of this type of structure is very high, it is common to use anchor bars to better distribute the effort and so that the external locking element does not deform excessively.

E plate; F plate

As the side openings are located at the mid-height of the pieces, it is possible to connect these pieces with the other components of the system with their smooth part facing downwards. Therefore, the piece has an 18 mm recess, which allows additional support that It can be made of wood, plastic or any other material found on site that is used when the total size of the slab is not a multiple of the size of the system plates. The ribbed structure of the part The bottom of the pieces had several points where wooden blocks could be housed to fix the complement using nails or screws.

G plate; F Plate

[0028] In addition to the side openings, for interconnection between the plates, the plates have “clamp” or “snap fit” structures (11) that serve to fix the plates.

H plate

[0029] L-shaped piece, can be used to shape the corners of pillars, bottoms of beams and external corners of walls. It was 60 cm long and molded 7x7 corners.

Plate I

[0030] L-shaped piece, can be used to shape slab-beam interface and internal corners of walls. It was 60 cm long, molded into a 23x8 corner.
