Abstract

Industrialized building system and construction procedure # Industrialized building execution system of one or more plants formed by prefabricated reinforced or prestressed concrete panels whose assembly is materialized by bolted joints without the need for welding or special mortars.

Description

Industrialized building system and construction procedure.

OBJECT OF THE INVENTION

The present invention relates to a prefabricated system for the execution of buildings of one or more plants based on vertical and horizontal prefabricated reinforced or prestressed concrete panels, with the vertical panels forming the facades and partition walls and the horizontal ones which They form the floor or roof of the buildings. The assembly of the different panels with each other is carried out by means of a novel screw connection system, without any other connection in the vertical plane of the joints such as welds or mortars commonly used in this type of buildings.

This new system aims to significantly reduce the costs of execution of traditional reinforced concrete structures, considerably improving the completion times and providing greater safety on site.

Likewise, the inconvenience of the costly and complex that is the execution of the different prefabricated panel joints of other systems that currently exist in the market is solved, allowing with this novel invention to provide the structure with a great rigidity.

The object of the invention is also a building construction procedure

The present invention is included within the construction sector and more specifically in the execution of building structures such as housing, schools, nurseries, etc.

BACKGROUND OF THE INVENTION

There are currently two systems for the execution of concrete structures: on the one hand there would be the concrete structures executed “in situ” and on the other hand the prefabricated structures.

The structures executed “in situ” are currently the most widespread form for executions in buildings and is based on using reinforced and prestressed concrete walls and slabs as resistant elements, subsequently concreting the entire assembly with the corresponding upper slab or compression layer. This procedure of execution is very laborious, since it requires a total or partial formwork in work and a lot of labor for the placement of all the resistant elements and formwork. With this system a good structural functioning is achieved, but it is extremely slow and causes numerous occupational accidents.

Prefabricated structures considerably reduce execution times and improve occupational safety. They have the disadvantage that the unions of the different prefabricated elements that form it are very expensive and laborious. These types of joints are usually executed by steel plates welded between panels or by concrete or fresh mortar.

The applicant is aware of the existence of other prefabricated systems for the execution of buildings such as the patent with publication number WO 2007/069877, which consists in the prefabrication of a complete plant including facades, compartments and floor slabs in one piece. This solution has the disadvantage of having to mobilize and manipulate very high weights, making the final product more expensive due to transport and lifting means.

The patent with publication number ES 2057993 consists of the execution of prefabricated structures based on supporting panels whose joints are made by means of welded metal plates between the different panels, requiring specialized labor and large amounts of steel, making the final product more expensive.

The present invention presents a prefabricated solution for executing buildings with one or more plants based on vertical and horizontal prefabricated reinforced or prestressed concrete panels, with the vertical panels forming the facades and partition walls and the horizontal ones forming the floor. or roof of buildings. The assembly of the different panels with each other is carried out by means of a new screw connection system, without any other connection in the vertical plane of the joints. In order for said joint to be efficient and sufficiently rigid, the panels have a recess in the horizontal surface of the upper corners where an L or T-shaped steel plate is hidden that is screwed vertically joining two

or three panels at a time.

Likewise, the panels that form the floor or roof are fixed by means of joints screwed to the vertical panels that form the exterior and interior walls of the building, giving the whole building a great structural rigidity.

ES 2 388 632 Al

It is also very important to mention that the panels do not need to be propped up, except the first one, at the time of execution, since before the crane has released the panel, it is already screwed to the previously assembled panel, thereby reducing the deadlines of assembly and the costs of auxiliary materials and labor.

DESCRIPTION OF THE INVENTION

The industrialized building execution system for one or more plants object of this invention is formed by vertical and horizontal prefabricated reinforced or prestressed concrete panels, with the vertical panels forming the façades and partition walls and the horizontal ones forming the floor or roof of buildings.

The façade and compartmentalisation panels have a recess in the horizontal surface of the upper corners where an L or T-shaped steel plate is hidden that is screwed vertically joining two

or three vertical panels at the same time, regardless of any other connection in the vertical plane of the joints such as welds or mortars.

Subsequently, the horizontal panels that form the floor or roof of the building that have through holes are placed along the edge in the area of the support on the vertical panels, where a plate is joined vertically that joins two consecutive horizontal panels together with the vertical panels on which they rest.

These horizontal panels are wider at the bottom than at the top, forming a longitudinal cavity that is subsequently filled with concrete or mortar poured on site that gives the whole a great resistance against horizontal solicitations such as those derived from wind action .

Finally and as an option, you can pour a layer of concrete on site over the entire horizontal surface.

The object of the invention is also a process of construction of industrialized buildings consisting of:

-

joining together at least two vertical façade panels and compartmentalisation by means of L-shaped or T-shaped steel plates -location of the horizontal panels that constitute the building's floor or roof panels -screwed vertical of the, at least one plate that joins two consecutive horizontal panels together with the vertical panels where they are supported. -formation of a longitudinal cavity between each two consecutive horizontal panels as these horizontal panels are wider in the lower part than in the upper part -filled with concrete or mortar of the longitudinal cavities formed between each two horizontal panels

 2. Statement motivated according to articles 29.6 and 29.7 of the Regulations for the execution of Law 11/1986, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement Document D01 (references in parentheses correspond to this document) discloses (see summary; column 5, line 1 column 6, line 63; figures 1,2, 6-11) a building system formed by reinforced concrete panels (see summary and figure 1) of facade (12,14,16) and compartmentalization (48, 50,52,54) and horizontal panels such as floor and roof (17-20), in which the facade and compartmentalization panels present (see Figures 7-10), on the horizontal surfaces of the upper corners, an L-shaped plate (68 in figures 10) or T (96 in figure 7, 112 in figure 9) joining at least two panels at once (14 and 50 in figure 7; 48 and 12 in figure 9; 12'and 16 in figure 10). The difference of this document with the first claim of the application is that the vertical panel does not have a recess where the plate is hidden but the recess is in the upper horizontal panel in the place of support on the vertical. It would be obvious to the person skilled in the art, in view of document D02 (see figure 1 and page 3, lines 22 to 33), that the recess for the plate may be in the vertical panel, whereby claim 1 does not I would have inventive activity. As in claim 2 of the application, document D01 (see figure 7) contains horizontal roof panels (18,20) with through holes (144,146) in the support area on the vertical panels (14,16,50) where a plate (156) is fixed by joining two consecutive horizontal panels (18,20) together with the vertical panels (14,16,50) on which they are supported. As in claim 3 of the application, the plates (96) of facade panels, and the plates (156) of the horizontal panels are joined by screws (90,92,94). As in claim 4 of the application the horizontal panels (17,18) (see figure 6 and column 6, lines 55-59) are wider at the bottom than at the top, forming a longitudinal cavity (191) that is subsequently filled with concrete or mortar (192) poured on site. As in claim 5, there is no other connecting element in the vertical joints between panels. As in claim 6, it would be obvious to the person skilled in the art, as an option, to lay a layer of concrete poured on site on horizontal panels, even if it is not contained in this document. Claim 7 would comprise all of the foregoing and would also be disclosed in this document D01. Document D03 contains (see figures 3-6 and column 1, line 46 to column 2, line 24) a joint (30) between vertical concrete panels (12,13) by a T-shaped plate (37) placed in recesses (32) on the horizontal surface of the upper corners as in claim 1 of the application, there being no other connecting element in the vertical joints of the panels, as in claim 5 of the application. In view of the above documents, the object of claims 1 and 5 of the application would be included in the state of the art and would therefore not be new (Art. 6.1 LP 11/1986). Claims 2-4 and 5-7 would be evident to the person skilled in the art, and therefore would not have inventive activity (Art. 8 LP 11/1986). State of the Art Report Page 4/4
