DE10315729A1 - On-site casting facility for producing pre-cast concrete parts has actuator acting upwards and formwork chamber able to be removed from top - Google Patents

Abstract

The casting facility comprises formwork chambers (2, 2a, 2b, 2c, 2d, 2e) and an actuator for the removal of the formwork from the pre-cast concrete parts. The actuator acts upward to break the adhesion, and the formwork chamber can be removed from the top. This may apply to formwork with walls (3) on a base.

Description

Farther will be a preferred addition to the Battery rotary switching method designed. The state of the art this can be found in particular in the inventor's PCT application dated July 22, 2002. Here are the individual building blocks (assembly line, Chord, etc.) explained which in principle make up the economics of the process.

The Rotary formwork with rigid chambers presented there was for filigree Repetitive structures thought, especially high-bay warehouses where the rough side came to rest at the bottom and was installed that way.

Farther followed on January 20, 2003 also the displaceability of heights and Sides of the formwork and somtit a more versatile beam geometry.

In the above statements became a turning possibility of finished parts in the air complements the also the rough concrete side, possibly with protruding connecting irons (Semi-finished parts) to turn upwards.

With wide prefabricated parts, the savings due to the simultaneous turning (stripping) of several parts with just one hand movement are not as great as with many small parts. With such wide parts, preferably over 40 cm wide or over 0.5 m ³ volume and particularly preferably over 0.5 m wide or over 1 m ³ volume, an operating mode can be optionally or preferred that consists of the formwork not to rotate, but to push the concrete parts out of the formwork by means of particularly powerful actuators for stripping, preferably by hydraulics, to such an extent that a hoist can lift the beam without having to pull the high static friction and the adhesive forces to the formwork wall. In addition, the dead weight does not have a relieving effect, but rather a strain on the actuator. Special measures for occupational safety are preferred in hydraulics, for example, to prevent hydraulic oil from spurting out, even over longer strokes, under typically 1000 to 7000 m water column. Encapsulation of lines, counterbalance valves, flow restrictors, etc. are representative here.

The Repetitive structures are no longer just preferred, as I said filigree, but also preferably more solid. Because the savings through Turning the formwork only becomes large if there are as many parts in it be included if the parts are more "delicate". The savings will be less if one additional Turning back, be carried out especially with many delicate individual parts got to.

The As of January 20, 2003, the multifunction device already introduced will be added preferably supplemented with a lifting device. This lifting device then preferably lifts several reinforcement cages at the same time. Especially preferably from a prepared shelf in which the iron maker his baskets either pre-fabricated or pre-fabricated delivered and defined can deposit, so that the subsequent reinforcement installation automated or accelerated.

alternative and depending on the construction site, a positioning of the Formwork should be sufficiently close to a tower crane. The special one economic operation here consists of direct excavation. and Put it down or take it out directly. and assembly in one single operation. All kinds of hoists are possible the TDK sweeps over however with very large construction site areas Effective radii of typically 30 to 55 m. It is still particularly suitable because the usual ones Unfold the approach of the mobile cranes, e.g. for smaller assembly cycles, which typically do not fill a whole day and so start-up and shutdown expenses of truck cranes.

1 shows such a turning device purely by way of example in a preferred embodiment.

1

A general with 1 designated precast concrete, with typical dimensions of 7.50 m × 50 × 40 cm ^{2 here} , is through two reversible loops 2 caught.

This Loops are wrapped around the concrete part lying on squared timber on the floor.

The two synchronous rotating tomatoes 3 are now able to turn the part after lifting. Here, 180 angles of rotation of the FT are selected, so that the side that is wider and rough with concrete from the turn-lock method points upwards in the air.

The crane now swivels with the traverse and the FT to the final assembly site. This path is now accompanied by the FT's striker, who can even be the crane driver (crane radio). At the final assembly site, one or two people turn or guide the crossbar 5 on a spike / cup of the support. The slight inclination of the crossbeam during assembly means that only an entanglement can be threaded in and the opposite one after a slight settling. There is no need to climb ladders for mounting on the support, as is usually the case. The crane operator now lowers the traverse, typically over 0.5 m, so that the good ones hang limply. The Rotomat now moves the belts so far that the release and closing device on the belt into one, here preferably on the tra verse even stably attached actuator 6 , introduces. This actuator now releases the belt loop. The belts fall limply and safely release the finished part.

Without manual work on the traverse can now be the traverse of a new one Stop position fed become. There the straps on the floor are removed from the striker again closed. The actuator will preferably reestablish the connection.

The telescoping ability of the traverse should also be mentioned 5 in one or more places 7 to allow a better adaptation to the geometry, here the lengths. The gel batteries 8th are with a hydraulic unit 9 only shown as an example The rope 10 goes to the hoist.

By 22.7.02 and 20.1.2003 were inventor's rights at the DPMA and registered as a PCT and deepened in various additional applications. subsequent Registration is particularly preferred in combination and combination with these procedures.

In particular The "battery rotary formwork process" was developed for the production and assembly of rod-shaped prefabricated parts referred to from the "bottom formwork method" Expectations and characteristics apply independently of each other or in combination, for Manufacturing, products, structure and processes.

In the WEBRO013 concerning a "assembly spider" from January 20, 2003 an assembly device has already been described, which finished parts mounted semi-automatically, which are on the ground. A lot of things in detail mentioned was also valid for this assembly device.

Now is due to the Drebschalverfahren that after turning the wide side must be thrown down so that the concrete at all comes from the inclined formwork. This is not just the rule statically undesirable but also by the customers because of the visible beams Concrete roughness, the lack of spreadability or the requirement hard to rework (cosmetics), not welcome. Thus it results the need for the finished part to rise 180 degrees in the air rotate. This turning should be particularly preferred in one operation and done safely with assembly. Furthermore, the assembly should continue semi-automatic, at least simplified, i.e. ideally should be struck with one person and especially knocked off can be Reversible belts and their are already known as prior art Rotary motors, e.g. so-called rotomatics. It is now proposed Such a Rotomat not only for turning the concrete part to use, but also for automated final assembly. This was mostly not possible until now, since after assembly of the finished part, e.g. of a single field beam, the Loops between. are caught in the supports.

According to the invention proposed a device that is easy to solve Strap connection generally enables particularly preferably a loosening the belt after assembly and particularly preferably operated remotely, e.g. but radio or over one hanging on the cable Switch.

The Power source is during the assembly in turn, preferably regardless of a supply on Soil, e.g. by batteries, better not leaking gel batteries preferably in connection with electrical or electrohydraulic Drives, so that also longer Swiveling hoists is possible wirelessly.

In known form in turn serve hanging means for manual Attack prefers ropes to guide of the finished part, especially against twisting and usually overhead. Thorn / cup constructions or entanglements, like from prefabricated parts known typically serve as supports. Particularly preferred also in connection with a non-positive connection after discontinuation or a hardening Connection.
