Abstract

The method involves using hydraulically movable telescopic supports which climb up with the storey levels and are set down through controls level at their ideal site. Several support parts can be connected together through overlapping joints. Independent claim describes screw threads in rear plate to take connecting screws. A steel sleeve can be driven into the plates in which a screw and nut can be turned.

Description

The The invention relates to methods and apparatus for improved floor construction according to the generic term of claim 1.

Even though Prefabrication currently this development is not without its importance Disadvantage. To mention are once the heavy transport with partial huge Components and the other the old building rhythm; Raise and only then install. And finally get the today's assembly buildings only by their core constructions theirs horizontal stability.

The subsequently presented invention has other starting points and therefore comes to other results. After simplified consideration exists a structure only from the columns and the floor ceilings. In contrast, according to this invention, the Support an additional Fulfill the task, they should raise the ceilings hydraulically to their nominal position.

The solution This object is inventively by the development of novel Supports possible. characteristics This idea is in the characterizing part of the main claim enumerated.

1 shows a longitudinal section through a hydraulic climbing column. Hereby, the principle of the invention will be presented. Tree-like like a fir the support grows upwards. Due to the overlap collisions, their cross-section becomes smaller and adapts to the load, which increases downwards.

2 shows a cross section through a stump stump. Here is the telescopic composition of the climbing column recognizable. It is like a column magazine, from which the individual pieces are lifted out from the outside to the inside. Above the stump is held together by a compound tongue. At the hub, the individual elements can automatically detach from it. Such stump stump would have to be factory pre-assembled.

3 shows an upper lap joint in the bolted joint. Here the screws are accessible from both sides. By intermediate stroke, the other can be tightened. Ties are only possible between the upper pair of supports on the inside during assembly. The mobility of the pendulum supports must be guaranteed.

4 shows two column plates with holes. The right has a screw thread on the inside, so a screw can be screwed in from the left and connect both support plates.

5 shows two column plates with holes. In it, a screw with internal screw thread can be hammered by hammer blow. By Stützenhub the water overlap shock is free, and now it is possible to screw the second screw from the other side in the first screw.

6 shows as before two columns plates with holes. In it, a connecting steel sleeve can be driven. And if the stroke is released by stroke, there is also the possibility here of pulling a screw from both sides.

7 shows a hydraulic climbing column. It consists of two half-piers with inwardly directed climbing socks. A half-support is movable and pen delt up and down. It is a pendulum support ( 1 ). The other is firmly anchored in the foundations and is a solid support ( 2 ). In between are two telescopically connected tooth jaws ( 3 ). In their round composite sleeves ( 4 ) are helical compression springs ( 5 ), which push them outwards onto the climbing socks of the supports. By two control screws ( 6 ) Both can be controlled. A sheet steel jacket ( 7 ) holds everything functionally together and also encloses the lower load yoke ( 8th ), for receiving ceiling beams ( 9 ). Above are still two nozzles ( 10 ) for connecting the support magazine ( 11 ). Accordingly, during the load stroke, the ceiling beams ( 9 ) and also the column magazine ( 11 ) lifted.

8th again shows enlarged the core of the invention. Shown are the tooth jaws ( 3 ) with their composite sleeves ( 4 ), which are put together and in which spiral compression springs ( 5 ) are inserted. Meaningful are also the two control screws ( 6 ), with them the entire construction process can be controlled.

9 shows the inside view of a tooth-jaw ( 3 ). Visible are the composite sleeves ( 4 ) and the tax screw ( 6 ).

10 shows a climbing column in mounting position. Both control screws are tightened.

11 shows a climbing column in lifting position. Both control screws ( 6 ) are gone.

12 shows a climbing column in parking position. The control screw on the fixed support is loosened and the other control screw is tightened on the pendulum support.

13 shows lift and extension of the climbing column. The pendulum support makes by the lifting cylinder ( 12 ) Up and down movements. It is advantageous that only low lifting force and small lifting height are necessary because only one blanket must be moved by control possibility.

At the Hubs are toothed by spring force climbing cams and toothed jaws. After stroke end, the pressure piston of the hydraulic goes down, however the bond with the solid support remains because of its tooth position is directed upward. As a result, ceiling and column magazine a stroke higher. A new hub can start.

When the floor level is reached, the hydraulics are switched off electronically and the next support is bolted to its lower one. From the accompanying magazine ( 11 ) one support after the other are pulled out. The column magazine stands on a load tongue ( 13 ), which, before the next stroke, is driven by a center screw ( 14 ) must be shortened.

The advantages of the invention.

To build is not only the installation of the material but also the hub for Installation site. It is a layering and has a similarity to a tree. Both have tipping safety through foundation or root system. And in both cases There is neither lifting crane nor scaffolding.

The column has a multiple function It not only raises the floor ceilings, but it is itself part of the finished structure. Overall, the invention has the following parts:

• 1. By adapted control option, the hydraulic stroke can be limited to a floor ceiling and push the building in the centimeter range with relatively little force upwards. Heavy lifting devices are therefore dispensable on the construction site.
• 2. It eliminates the transport and movement of large equipment and heavy components.
• 3. The raised first cover is working platform for assembly work on the column extension.
• 4. Due to the sliding weather tent, the construction site is free from the weather and also permits winter work.
