Description

Modular structure for the formation of submerged formwork. Object of the invention

The present invention, as expressed in the statement of this specification, refers to a modular structure for shaping submerged formwork, more specifically intended for the construction of concrete footings that act as the basis for bridge pilasters on river beds. , marine, alluvial, etc.

Thus, in certain circumstances the generation of a concrete shoe in areas of high water table, riverbeds, lakes, etc .; It requires complex and arduous formwork tasks to create concrete walls and drains from the interior area where said shoe will be generated.

In order to avoid these mentioned inconveniences that sometimes forces to change the development of the work and / or slow down its execution due to the problems of concreting in flooded areas, the modular structure of the invention has been developed. Background of the invention

At present, to carry out the formation of submerged formwork and more specifically the formation of concrete footings that act as a basis for bridge pilasters on river beds, sea, alluvial beds, as referred to in the previous section, in certain circumstances the generation of a concrete shoe in areas of high water table, riverbeds, lakes, etc., currently requires complex and arduous formwork to create concrete walls and drained from the interior area where the shoe will be generated. Description of the invention

In order to achieve the objectives and avoid the drawbacks mentioned in the previous sections, the invention proposes a modular structure for the formation of submerged formwork characterized in that it comprises double wall modules, with joining means between them to form a closed contour of side walls of any geometry that is required, so that the different double wall modules are joined by means of characteristic means.

Thus, the modular structure is composed of double wall pieces braced internally to withstand the pressure of the interior concrete filling and attachable to each other, to form a central space that will coincide with the concrete footing.

As previously described, the modules can generate any final geometry comprising connection means between the different adjacent modules.

The operation is simple because it consists of placing the closed structure on a pre-concreted base

or without concreting, in which case the inner wall of the modules will be slightly shorter than the outer one, that is, that the lower edge of said inner wall will be separated from the floor at a certain height corresponding to the thickness of the concrete base which will be generated later, to give continuity to the concrete mass.

Subsequently, the concrete mass is poured into the intermediate space delimited between the walls of the modules by filling the sides to form a closed perimeter wall, and the base in the event that the aforementioned pre-concreted bed does not exist.

In both cases, we managed to create a concrete structure as a drawer formed by side walls and bottom, open superior and tight, for the pouring and formation of the shoe, and covered laterally by the structure of the device in question that is lost.

Subsequently, we will proceed to extract the water and carry out the work of work in the interior, placement of ferralla, headless of piles, or any other activity such as the pile-up.

In order to facilitate a better understanding of this descriptive report and forming an integral part thereof, some figures are attached in which the object of the invention has been shown as an illustrative and non-limiting nature. Brief description of the drawings

Considering the numbering adopted in the fi gures, the modular structure for the formation of submerged formwork is determined from modules, straight 1 and angular 1 ', double-walled: exterior 2 and interior 3, with internal bracings 4 to withstand the pressure of the concrete mass that will be poured when appropriate in the intermediate gap 5 delimited between such walls2 and 3 of the modules, once the entire modular structure of closed contour is formed that delimits a central space 6 that will coincide with the shoe to be concreted in correspondence with the bottom of that central space 6.

Thus, the modular structure of closed contour can be placed in a first case on a concreted base7 and a second case on a lower surface 8 without concrete to give continuity to the corresponding concrete with the bottom of the central space 6. In this second case, the internal walls 3 of the modules 1 will be shorter, so that their lower edge will be located above that inner surface 8 without concrete.

Then, once the modular contour structure is assembled, the concrete mass is filled to fill the intermediate gap 5 delimited between the double walls 2 and 3 of the modules 1 and also the bottom bed of the central space 6 when it comes to the lower surface without concrete.

In both cases, we managed to create a concrete structure as a drawer formed by lateral walls and open bottom superiorly and tightly sealed, for the pouring formation of the shoe, and covered laterally by the modular structure of the invention that will be lost.

Subsequently, the water is extracted and the veneering work done with some piles 9, as mentioned in previous sections.

On the other hand, the different walls 2 and 3 of them

1-1 ’modules have a perpendicular end plates 10 that contact each other when adjacent 1-1’ modules are mounted including said perpendicular end plates 10 facing holes 11 to ensure their fixation by means of fasteners not shown in the fi gures. The fixation of the perpendicular end plates 10 is reinforced by small brackets 12.

To reinforce the connection between modules 1-1 ', pairs of upper supports 13 are provided provided with facing holes 14 through which threaded rods 15 are inserted where a nut 16 is interposed with an interposition of a washer 17.

In the lower part of the modules 1-1 ’, vertical screws 18 are provided, coupled with nuts 19 integral to the outer walls 2 of the modules 1-1’ to level and position the modules relatively high.

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 The invention relates to a modular structure for the formation of submerged formwork, especially for the construction of concrete footings, comprising double-wall modules with internal bracings inside which concrete is poured, joining means consisting of perpendicular plates with perforations. faced for the introduction of fasteners vertical screws coupled to the walls to level and position in height. Document D01 discloses a submerged formwork for the formation of a cubic block of concrete with a simple, modular wall, where the different modules have perpendicular plates perforated facing each other and crossed by screws (see figure 1). However, it is not a double wall module, nor does it have the means to level and position the different elements in height. Document D02 refers to a formwork for the manufacture of swimming pools. It is a double wall formwork, which includes bracing (4). The inner wall is elevated with respect to the outside, so that the concrete that is poured inside the formwork comes out from the bottom to form the floor of the pool. Document D03 discloses a double wall formwork for obtaining a "dry" area around a structural element submerged in water. As can be seen in the drawings, it has internal bracing elements (6). Documents D04 and D05 disclose devices intended for construction submerged by concrete. None of the documents comprise all the technical characteristics of the invention defined in claim 1 and therefore this and claims 2-4, dependent on the above are new (Art, 6 LP 11/1986). Similarly, it does not appear that one skilled in the art has reached the invention, as defined in claim 1, from the state of the art discussed above, therefore it is considered that the invention defined in claim 1 is new and implies inventive activity (Art.6 and Art.8). The same can be said of claims 2-4, depending on the previous one. State of the Art Report Page 4/4
