Description

35

The invention relates to a plant for the production of precast concrete parts according to the clock process under Use of successive production stations with production tables, which are arranged in a ring and at least partially by means of a process bar roof are covered, with a tower crane arranged in the center of the ring, whose boom sweeps over the production tables, with outside the Annularly arranged bearings for the precast concrete parts and with a concreting machine and a Concrete mixer.

Such a system can be found in DE-AS 13 01 751. In this known system, the concrete mixer is arranged directly next to the tower crane. This means that the concrete bucket must be transported inside the column and from there along the boom of the tower crane. The tower crane is thus is a special crane.

For the removal of the finished concrete parts , a second tower crane is required, which can be moved on rails between the production tables and the bearings. In the area of the production tables, the booms of the two tower cranes overlap.

Concreting takes place outdoors. Only the other work can be carried out under movable working roofs be performed. Part of this work is done before concreting and part after it is poured of the concrete is carried out into formwork, the working roofs have to be moved back and forth. To the Inside the ring, access for transport vehicles to the concrete mixer must be provided.

The invention is based on the object of designing a system of the type mentioned at the outset in such a way that all work on the production tables can be carried out under a roof and the tower crane essentially carries out all transport work

This object is achieved with the features specified in the characterizing part of claim 1. Advantageous refinements of the invention can be found in the subclaims.

It is possible to use the segment-like section of the roof, which fiber-spans all the production tables the boom of the tower crane to transport concrete from the concrete mixer to the concreting machine, which is then fed from the concreting machine to the individual production tables. Finished concrete parts are taken from the boom of the tower crane Production tables transported to the warehouse Thus, the main transport work is carried out by the tower crane. All work on the production tables is carried out under a roof

An exemplary embodiment is explained in more detail below with reference to the drawing

F i g. 1 is a schematic plan view of the installation;

2 shows a section through the system, seen in the direction of arrow B in FIG. 1; and

F i g. 3 shows a further section through the system, seen in the direction of arrow A in FIG. 1.

The entire task is divided into several concentric circles or rings. In the center is the tower crane T. Its jib reaches the entire arrangement shown. The tower crane T takes over - apart from the still to be described gantry crane-like concrete machine - all transport tasks, especially in the radial direction.

In a first ring around the tower crane Γ, partitions 1 are arranged for prefabricated parts that are to be built into the precast concrete parts. Depending on requirements, the partition walls can extend over a larger or smaller part of the circumference.

In a second ring further away from the center there are partition walls 2 for structural steel mesh that is to be inserted into the precast concrete parts. Additional rings for storing parts to be installed can be provided as required.

Another ring with the actual production tables 3 follows. At tables 3 can open or concealed channels 12 may be provided. This can be done through them and through the annular channel 13 during manufacture Waste water from exposed aggregate concrete slabs can be diverted to the washing pit 4.

The ring of the tables 3 is spread over by the concreting machine 11, which is designed in the manner of a portal crane. she is can be moved on the crane runway rail 5.

A storage bin ring for stacking the finished products is located concentrically around the ring of the tables 3. Wall elements are set vertically in a rotating rake 7; Ceiling panels 8 are optional also stacked horizontally. The finished products are then available further radially outward Container 9 or loaded onto pallets. At the outermost edge of the circular manufacturing facility is located the concrete mixer 10.

A roof 15 is provided to protect against the effects of the weather. So that the whole work area from Tower crane Γ can be reached, the roof 15, which is provided with a segment-like cutout, twist. The segment-like section is shown in FIG. 1 indicated by dashed lines. Outside of operating hours, it is placed under a fixed roof part (not shown) screwed in. This fixed roof part is located

located directly across from the cement mixer 10. It is so large that it completely covers the movable, segment-like cutout in the roof 15

Because the area under the fixed roof part is not accessible to the tower crane T, the Washing pit 4 arranged. Among other things, it serves to clean all devices, especially the pouring machine, after work is finished.

The roofed-over space is closed to the outside by the wall 6 and the Tunv Drehkran Γ by the wall 16.

During operation, the workforce goes in a circle from table 3 to table 3. The parts to be installed become radial brought to the outside and mounted on the respectively processed table 3 The concreting machine 10 and the seg- is ment-like section of the roof are carried along accordingly

The bound precast concrete parts are lifted from the tables and further out: brought to their stacking places and loaded from there.

In the schematic Figure 2, the concreting machine is just above a manufacturing table 3, in the schematic FIG. 3 above the washing pit 4.
