Description

DESCRIPTION
BUILDING SYSTEM WITH SINGLE ELEMENTS WITHOUT FORMWORK
FIELD OF ART
The invention refers to the field of fixed construction techniques and more specifically to the field of construction methods. More specifically, it refers to the field of building tools and systems and their use, to the handling of building materials at the place of construction, and even more specifically, it refers to a building system with single elements without the use of formwork.
BACKGROUND OF THE INVENTION
The formworkless building system with single elements disclosed in the present invention has not been disclosed in the prior art.
Building methods used worldwide include a range of styles and materials. There are therefore conventional constructions using concrete, stone houses, mixed constructions, metal buildings, but also prefabricated buildings made of concrete or with metal elements, among others. Conventional construction using concrete is the most familiar way of construction compared to the most modem ways of building construction, such as mixed constructions, metal buildings and prefabricated buildings, because it is the most tested and is considered the safest way of construction in Greece. Despite this, it presents a number of disadvantages since it requires a longer delivery time, compared to other types of construction, it is a more expensive way of construction compared to other methods, it has less design flexibility, it presents difficulties and high costs in repairing damages, while quality control is also more difficult.
On the other hand, the rest of construction types present different disadvantages, which make them still unprofitable and deficient compared to the conventional technique, as a result of which they have not prevailed widely. Thus, metal buildings, being made of structural elements without heat capacity, cool down as soon as heating is turned off. In addition, the maintenance of the metal frame, whether it concerns painting or tightening of screws, cannot be done in the future without removing the cement board. It is not always necessary, but especially in the case of paints, there is no guarantee that a proper pre-treatment has always been done. In addition, there is reduced fire safety, reduced sound insulation, as well as limited renovation possibilities. Similar issues exist in prefabricated building structures, which prevent their widespread use for housing needs.
It is therefore an object of the present invention to advantageously address the aforementioned disadvantages and shortcomings of the prior art by proposing a building system with single elements without formwork, which will take advantage of both the construction quality of a reinforced concrete building and the possibilities of alternative constructions in terms of speed of construction.
It is a further object of the present invention to provide a formworkless construction system with single elements using expanded polystyrene, extruded polystyrene, rockwool elements, replacing conventional masonry. It is a further object of the present invention to provide a construction system with single elements having a cross-sectional channel for filling with rebar and concrete.
Advantages of the invention are the reduction of the time of construction and completion of the building, the ease of placing the parts, as well as the zero maintenance required. In addition, the system is fire resistant and has a long service life.
A further advantage of the invention is the energy efficiency, the waterproofing and the thermal sound insulation provided, due to the insulating materials that are basic elements of the construction. In addition, precisely because of the properties of the materials used, the system exhibits high seismic resistance.
Another advantage provided by the construction system with single elements is that it allows easy access to other construction technicians, such as plumbers and electricians, so that they can in turn install their own systems.
Additional important elements of the present invention are that during the installation and application of the system, the concrete does not crack and above all the rebar of the columns of the building do not rust.
In addition, the external coatings of the structural surfaces can be made of fire-resistant materials, as well as various structural and decorative materials of any kind and geometric shape, such as coloured coatings, etc. Similarly, the internal surfaces of the system can be coated with any structural, refractory and decorative material, regardless of its type or geometric shape. An advantage of the present invention is also the fact that the speed of completion makes it ideal for constructions, such as hotel units, while it becomes possible to build in inaccessible areas, where access to materials is difficult. In addition, the specific construction methodology can be used from the foundations of the construction to the masonry, but also in the construction of swimming pools, providing flexibility to the user.
Another advantage of the invention is that it contributes to the protection of the environment, since not using formwork helps to reduce tree cutting, creating energy ecological buildings.
These and other objects, features and advantages of the invention will become apparent in the following detailed description.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention will become apparent to those skilled in the art by reference to the accompanying drawings in which it is shown in an illustrative, non-limiting manner.
Figure 1 is a perspective view of the top side of a structural element without form work, so that the parts that make it up are visible.
Figure 2 is a plan view of the corresponding structural element of Figure 1.
Figures 3 (a) - (i) show variations of the construction system with single structural elements without formwork and which are used depending on the respective installation and implementation. DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
Referring now to the accompanying drawings, we will describe exemplary embodiments of the formworkless construction system with single elements.
The main structural element (1), Fig. 1, consists of a single insulating material, preferably expanded polystyrene. Alternatively, extruded polystyrene or even rock wool can be used as a material. Its shape can be rectangular with corner ends, either semicircular, Fig. 3 (f), or T-shaped, Fig. 3(b), or any other desired and suitable shape. The structural element (1) has walls (2) of insulating material, which create a channel (3). Inside the channel (3), Fig. 2, there are level steps (4) for placing and filling with rebar and concrete. The steps (4) can have any shape, following the shape of the main structural element (1). Thus a step (4) can be formed at an acute angle, Fig. 3(d) or at an obtuse angle, Fig. 3(g) of the main structural element (1). In each comer of the main structural element (1) a hole (5) can be formed, which is aligned with the corresponding hole (5) of the upper or lower structural element (1) for filling the columns with reinforced concrete. As it becomes obvious, the dimension of the main structural element (1) allows it to be doubled, in order to increase its height according to the needs of each construction. The structural elements (1) are connected to each other by any suitable means, such as oriented strand boards, also known as OSB, or aluminum beams or any other suitable means. OSB is a type of laminated wood product, which is composed of long and wide pieces of wood, to which thermosetting adhesive is added, and after lamination, they are pressed in a hot press to be welded. The specific wooden boards act as connectors and contribute to the structural elements (1) becoming one body with each other and remaining in place. Aluminum beams or any other kind of beams will have a similar function.
The application of the construction method with the specific building system includes the placement of the structural elements (1), after the cleaning concrete, following the outline of the floor plan, in order to give the final outline of the building. The bars are placed inside the channel (3) and on the steps (4). After the first layer is placed, the OSB joints are placed. On top of the first layer of structural elements (1), the following structural elements (1) are placed, giving the necessary shape and height to the construction. When the desired height of the structure is reached, according to the figures, concrete is injected both into the channels (3) and the holes (5), until it reaches the top.
It should be noted at this point that the description of the invention was made with reference to indicative implementation examples to which it is not limited. Consequently, any change or modification regarding the shape, dimensions, morphology, materials used and construction and assembly components, as long as they do not constitute a new inventive step and do not contribute to the technical development of what is already known, are considered included in the purposes and aspirations of the present invention.
