ES2277549A1 - Concrete piece manufacturing method for producing concrete pieces with wooden appearance involves adding dyes of same color as wood to concrete before concrete is poured into mold - Google Patents

Abstract

A framework is disposed within a mold into which concrete is poured. The concrete is allowed to set until cured, and the resulting piece is removed. The mold is equipped with suitable reliefs to produce reliefs similar to wood on the concrete piece. Dyes of the same color as wood are added to concrete before the concrete is poured into the mold.

Description

Procedure for obtaining pieces of wood-like concrete

Object of the invention

The present invention relates to a procedure for obtaining concrete parts with wood look

Background of the invention

There are currently several elements construction and / or architectural made of wood, such like doors, windows, pergolas, beams, pillars, corners, sockets, balustrades, etc., especially in buildings of rustic type.

However, wood requires certain care,  especially if it is subject to weather conditions: example you have to sand it and varnish it or apply oils preservatives since otherwise it may end up rotting, and This even though these cares are carried out.

On the other hand the wood, although it has a acceptable mechanical resistance, is limited compared to other construction materials such as concrete or steel, so that you can't, for example, get big lights between braces or beams if it is not by exaggerated oversizing of the wooden building element (beam).

That's why the construction systems used currently they have abandoned the use of wood, and use structures with steel or concrete pillars that support slabs of concrete. If for example you want to make a decoration Rustic on one of these concrete slabs the application of hanging decorative beams in light materials and high price.

These inconveniences are corrected with the use of the method of the invention.

Description of the invention

The process of the invention serves as a Optimal way to get sturdy reinforced concrete parts that have the appearance of pieces of wood, which allows their Direct view utilization in rustic environments, gardens, etc. as much as decorative or even resistant pieces.

According to the invention the procedure it comprises the manufacture of a mold or formwork in which they place the relevant reinforcement and ready concrete is poured, that once set and if cured, is demoulded to obtain the piece.

The particularity that the invention proposes is that the incorporation into the mold or formwork of some reliefs that simulate the reliefs of the wood, such as streaks, stretch marks, knots, etc., reliefs that they will be integrated in the finished piece.

In addition, it is also planned to add in the preparation of concrete, and before pouring into the mold, about suitable color dyes that simulate that of the wood itself, of so that the piece in all its volume will have the color of the wood, and not only superficially, so in case of fractures or chipping will not show color difference, or the Natural gray color of concrete. Anyway either the invention would distort the fact of applying the dyes superficially to the piece once set.

Figure 2 shows a detail of the connection between the pieces of the pergola shown in figure 1.

Description of a practical embodiment of the invention

The process of the invention comprises the stages of:

- Make a concrete preparation of the appropriate characteristics, with the particularity that it is added a brown dye similar to that of the wood to simulate, which it will color the volume of the finished piece in its entirety.

- Prepare a mold or formwork based on parts that incorporate a relief that simulates streaks, knots, stretch marks and / or other reliefs of the wood placing inside, if precise, the necessary armor.

- Pour the concrete into the mold and leave set under proper curing conditions if required.

- Unmold.

- Optionally retouch.

The pieces so manufactured can mimic the appearance of constructive elements such as segments, balustrades, corners, baseboards, railings, doors or windows, capitals, column bases or any others, sizing properly the armor and providing in them the means of coupling with other parts.

For example, in the case of pergolas as shown in figure 1, porches 2 with pillars 3 are made and jácenas 4, interspersing capitals 5, and resting on the porches some joists 7, and where appropriate, some bends 8, being all these parts manufactured according to the invention.

As an example, they are intended as means coupling between pillars and jácena, as seen in figure 2, a round 6 that crosses the capital and is embedded both in the end of the beam as in the jacena, filling, not represented, epoxy resin.

The pillars are obviously anchored and / or cemented to the pavement, and the joists can rest on a plurality of these porches, or on a porch by one of their ends, with the corresponding overhang, and in an enclosure or facade, not represented, on the other.

Describe sufficiently the nature of the invention, as well as how to perform it in practice, should be noted that the provisions indicated above and represented in the attached drawings are susceptible to modifications of detail as long as they do not alter the principle fundamental.
