Abstract

A concrete structure consisting of at least two juxtaposed prefabricated concrete wall elements (1) should be formed so wide that even during the joining a positive connection takes place, which makes it unnecessary to further hold the individual precast concrete wall elements until final bonding. For this purpose, it is proposed that the precast concrete wall element (1) has on at least one of its sides joined to another precast concrete wall element (1 ') a first area with a projection (2) and that a second area of the side has a recess (3). for receiving the projection (2 ') of the first region of a second precast concrete wall element (1') has and that the precast concrete wall elements (1, 1 ', 1n) in the height of the respective regions are joined together offset.

Description

The invention relates to a concrete structure consisting of at least two juxtaposed precast concrete wall elements.

Such concrete structures can be made of precast concrete wall elements composed protective walls, but also walls of containers, buildings or towers.

The EP 2 239 398 A1 For example, discloses a tower made of such precast concrete wall elements. Here, the precast concrete wall elements are joined together in climbing construction. The joining itself, however, is still problematic because the individual loose elements must be kept until a connection has been established with the already existing precast concrete wall elements.

The invention has the object of providing a concrete construction in such a way that even when joining a positive connection takes place, which makes it unnecessary to further hold the individual precast concrete wall elements until the final connection of the same.

To solve this problem, it is proposed that the precast concrete wall element on at least one of its assembled with another prefabricated concrete wall element sides has a first region with a lug and that a second region of the side of a recess for receiving the approach of the first region of a second precast concrete Has wall element and that the precast concrete wall elements at the level of the respective areas are offset from each other.

The projections of a precast concrete wall element fit together in a complementary manner with the recesses of a second precast concrete wall element. If several prefabricated concrete wall elements are already joined together, another element can be inserted into the vertically offset joint between the elements. The newly used precast concrete wall element is placed on a horizontal side of a lower precast concrete wall element and leaned against the reaching into the gap approaches the already existing ready-mixed concrete wall elements.

In addition, there is the possibility that the approaches of the newly inserted precast concrete wall element are supported with their lower edges on the upper horizontal sides of the already existing precast concrete wall elements. The newly used ready-mixed concrete wall element is relatively stable by the supports in the vertical and horizontal directions, so that regularly only a tilt protection is necessary. As a result, the newly used precast concrete wall element can be connected to one another without further joining and connection.

It is advantageous that the approach of one of the wall surfaces of the precast concrete wall element starting substantially half the thickness to a maximum of the thickness of the precast concrete wall element and that the recess is provided in the region of the same wall surface and in depth substantially half the thickness to a maximum of the thickness of the precast concrete wall element corresponds.

By this measure it is achieved that several precast concrete wall elements can be joined together, without causing a jump in the thickness of the concrete structure in the seam areas.

It is expedient that the projection and the recess each correspond substantially to half the height of the precast concrete wall elements. As a result, the assembly of the precast concrete wall elements to a concrete structure is particularly easy and quick to accomplish.

Although gaps may still remain in the area where the precast concrete wall elements are placed on a foundation, or in the upper end of a concrete structure, it makes sense to close them. For this purpose, it is proposed that second prefabricated concrete wall elements are provided which essentially have the height of the recesses and which are provided with a shoulder over their height, and that third prefabricated concrete wall elements are provided which essentially have the height of the projections and which are provided with recesses over their height.

With these usually half the height of the precast concrete wall elements can be readily the gaps that would arise in a construction of the precast concrete wall elements on a foundation, and also at the upper end z. B. a tower, close.

To form concrete walls made of straight walls, it makes sense to make the lugs in a plane with the outer surfaces of the precast concrete wall elements. However, if polygonal concrete structures are to be created, it makes sense that the lugs protrude at an angle from the precast concrete wall elements. The angle is freely selectable, but usually results in the number of planned corner to close a container, a building or a tower from all sides It is significant that the joined precast concrete wall elements at least in the area Overlap of approach and recess are positively connected to each other, Here can be adhesive, but also think mechanical connections, the adhesive between approach and recess z. B. can be selected in the form of fresh concrete. But it is also possible to connect by screw or other mechanical connection means the precast concrete wall elements with each other.

An even better introduction and takeover of forces in different directions is achieved when the lugs are provided in their, the recesses facing area, with springs and / or grooves and the recesses delimiting areas of the precast concrete wall elements, complementary grooves and / or springs exhibit.

The invention will be explained in more detail with reference to a drawing, in which:

1 a precast concrete wall element,

2 a section of a tower created in climbing construction, z. B. a wind turbine, and

3 a section through two assembled prefabricated concrete wall elements shown in sections.

1 shows a precast concrete wall element 1 which is in the area of its upper half with lugs 2 . 2 ' are equipped. The approaches are here z. B. arranged at an angle of 45 °, so that an octagonal construction would result in total. Other angles are of course conceivable, the angles being smaller, the smaller the number of planned corners, becoming larger. The larger the number of planned corners of the concrete structure, the smaller the corresponding angles.

In the lower part of the precast concrete wall element 1 has this recesses 3 . 3 ' on. Should several prefabricated concrete wall elements 1 z. B. be assembled into a tower, so would an approach 2 a precast concrete wall element 1 a recess 3 ' pre-set a second precast concrete wall element.

2 shows the assembly of several precast concrete wall elements, wherein it can be seen that in the lower region of the tower section second precast concrete wall elements 4 are provided while not shown approaches, for. B. in the recess 3 . 3 ' adjacent precast concrete wall elements 1 fit.

3 shows a section of two joined prefabricated concrete wall elements 1' where both precast concrete wall elements 1' are shown in section. Here it can be seen that in the approach 2 '' feathers 5 are provided, which in Nute 6 , the recess 3 '' engage limiting wall parts.
