Description

The invention relates to a method for producing plate-shaped Structures made of prefabricated components lying next to one another, which are secured by transverse prestressing are pressed together so that they touch on flexible contact surfaces, after which the joints between the components are filled.

It is already known to interconnect prefabricated concrete parts in the way to connect to a structure that between the concrete parts when laying initially The joint spaces that have been kept free are filled with grout and, after it has hardened, a Preload z. B. is applied by means of tendons. The disadvantage here is that the structure can only be loaded after the grout has hardened. Another disadvantage is that any movement of the individual concrete parts with each other must be avoided in order to adversely affect the grout until it has taken place To avoid hardening and the application of the bias.

These disadvantages are admittedly when applying contact joints that on the most varied and well-known types are produced with great effort can be avoided, but it is necessary here to use the precast concrete elements must be laid very precisely during assembly in order to meet the support conditions that arise cannot be changed by clamping if intermediate storage is avoided shall be. Otherwise, especially z. B. for large areas and from many parts composite structures are assembled on a special assembly frame and then settling on final storage is required.

The object of the invention is, in a method for producing plate-shaped structures made of prefabricated parts to avoid the disadvantages mentioned. On the one hand, the requirements on the accuracy of the contact surfaces should not be too high and on the other hand an immediate, at least partial resilience of the structure can be achieved after prestressing.

The problem is solved with a method of type described in that the components with intermediate layers of elastic Material must be laid that enclose the joint space.

The elastic intermediate layers make the advantage of a substantial one Easier production of the precast concrete parts compared to when using pure Contact joints achieved because tolerances in the joint plane are easily bridged can. Furthermore, any intermediate storage of the finished parts can be dispensed with, as the elastic intermediate layers as long as the remaining joint space is not covered with grout is filled, allow deformations and thus the support conditions of the individual Finished parts that have been displaced in their final position are not changed.

Further refinements of the subject matter of the invention are the subject matter of the subclaims.

The method according to the invention is explained with reference to the drawing. It shows F i g. 1 shows a cross-section through a solid structure composed of prefabricated parts, FIG. 2 shows a section along line 11-II in FIG. 1, Fig. 3 shows a cross section through a supporting structure made of steel and precast concrete parts, FIG. 4 a connection between two prefabricated steel parts. Prefabricated components 1, which according to the embodiment of FIG. 1 z. B. are made of concrete are made with as plane-parallel joint surfaces as possible in the area in which the elastic intermediate layers 2 are installed. The boundary surfaces in the rest of the joint area are designed so that the resulting joint space 4 is so large that the grouting material can be easily introduced. The joint boundary surfaces 5 are also profiled in this area. The components 1 have recesses 6 for inserting tendons 7. When assembling the elastic intermediate layers 2 are each applied to a joint surface, for. B. glued. A seal between the joint space 4 and the recess 6 is also achieved by an elastic intermediate layer 13 surrounding the recesses 6. Then, the next finished part is attached, etc. After the biasing of the Spannglieder7 the power flow runs between the finished parts through the intermediate layers 2 and 13. Various thicknesses of the intermediate layers 2 and 13 of the power flow can be controlled by the intermediate layers. 2 The ends of the prefabricated parts are sealed with sealing strips 11. The joint spaces 4 are then pressed out via a press-in channel 10. Reliable backfilling is ensured by a vent 12 at the joint ends.

With the re-tensioning of the tendons 7, a partial overpressure is achieved of the potting in the joint space 4 allows.

When assembling a structure made of steel and precast concrete parts and steel parts with each other is proceeded analogously to the above.
