Structure, especially bridge superstructure

The invention relates to a supporting structure, in particular a bridge superstructure, with a hollow box cross-section, in which a cross member is arranged in the pillar area, which allows vertical forces to be applied for a short period of time Initiate lifting and lowering of the structure within the box girder.

Structures with box girder cross-section are known, in which the introduction of the forces on the underside of the supporting structure, with a clearance between the pillars and the superstructure corresponding to the press units must be present. In modern bridge construction, bridge bearings with such a small height are predominantly used used that such an arrangement of presses is not possible. To the. This deficiency will be circumvented Recesses for the press units are provided in the area of the support bench. With low pillar heights it is also possible to arrange the presses on auxiliary supports. .

The known designs have the disadvantage that a high level of additional set-up work is required is required to enable the presses to be installed, removed and attached safely, which is particularly disadvantageous with high pillars! for installing and removing the heavy press units special load handling devices are required on each pillar, which - according to the! of the work must be implemented.

In the known structures affect the inevitably required for setting up the presses Press niches or, alternatively, base arrangements in the area of the bearings create a closed picture of the building.

The purpose of the invention is to find a structural form of the structure in which, while maintaining the continuous execution of the pillar up to the superstructure, a lifting of the supporting structure, which on Storage with low height rests, becomes possible by pressing.

The invention is based on the object of providing an arrangement through the structural design of the supporting structure from eating to lifting the superstructure without heavy armor and constant use of hoists to Moving the presses, taking into account the maintenance of the closed shape of the structure enable.

According to the invention the object is achieved in that the section of the hollow box structure in the pier area, in which a cross member is arranged, is constructed so that through recesses in the closed base plate of the hollow box and by opposing arrangement of consoles on the cross member the installation of the presses within the bridge cross-section is possible, with the necessary presses directly or in the middle of the spacers on the pillar rest and the compressive forces that occur are absorbed by the consoles and transferred into the structure. It must be taken into account that the stresses that occur in the pillar due to the press forces must be absorbed are;

When using the solution according to the invention, ea Corrections possible after completion of the building in the height of the superstructure as well as a replacement

of bearings, preferably rubber pot bearings, by placing the seizures in the superstructure,

Furthermore, it is not necessary to set up heavy equipment, especially on the pillar. The assembly of the presses does not require a great deal of time. When installing the presses, the work process within the closed box girder cross-section from a fixed, built-up work level can be carried out, whereby any danger to workers against falls is excluded. In addition, there will be closed lines within the transition from the pillars to the superstructure guaranteed and the overall impression of the building improved. The invention will be explained in more detail below using an exemplary embodiment. In the drawing demonstrate:

Fig. 1: the cross section of a bridge superstructure, Fig. 2: the section A-A according to Fig. 1,

Fig. 3: the section B-B according to Fig. 1. In the box girder 1 in the area of the pillar 2 is a Cross member 3 arranged. In the closed base plate 4 of the hollow box 1 are above the pillar 2 Recesses 5 and arranged on the cross member 3 brackets, which in the existing space 7 the Allow installation of press units. There is a direct introduction of pressure into pillar 2 as well as (

over the consoles 6 in the box girder. The press installation process is carried out within the closed Hollow girder cross-section carried out, the presses with the help of an assembly trolley and can be expanded and implemented through the openings 8 in the cross member from one pillar to the other.
