Description

FIELD OF THE INVENTION

The invention relates to a method for manufacturing and assembling on a construction site using a tower crane and power supply devices and using a platform that serves as formwork, formwork skin for a floor ceiling and/or for inserting a supporting wall.

It also relates to a device for carrying out such a method.

The publication DE 196 44 848 A1 is generic and provides the characteristics that make up the generic term.

When assessing the state of technology in construction and everything that does not belong to this area, one must especially emphasize the considerable superiority in mechanical engineering from the point of view of technical solutions and modern means of their implementation. It is not a coincidence that e.g. B. Means of transport, limited only two centuries ago to horses and sailing ships, today produce amazing results on and underground. There is no comparison in the thousands of years of construction history.

Radio-controlled tower cranes are currently used and monolithic construction is achieved by setting up numerous formworks, with the shell structures being manufactured in the project location (on the construction site).

The development and logistics of these formworks, scaffolding, assembly- and tolerance-friendly devices are carried out in companies specifically designed for this purpose, some of which are large and are known and active not only in Germany, but worldwide.

The DE 2 256 262 A describes a method and device for producing multiple floor slabs with only one formwork arrangement.

The AT 21 30 36 B describes a formwork for solid ceilings, beams, supports and the like, which can be assembled from a few flexible elements.

CRITICISM OF THE STATE OF TECHNOLOGY

Both in construction literature and in preparation for work on construction objects, there is a division of functions between different specialists, but the decisive and binding role is played by the commissioned architect, whose competence is limited outside of specific construction problems and construction planning. Therefore, conceptual decisions should only be made with the help of qualified building physicists in the broader sense (plus structural engineers, plus high-tech specialists).

The outdated function of a tower crane only as a load transfer reduces the time it takes to utilize its performance and should be significantly expanded.

Attaching and unhooking hooks for structures as well as opening and closing concrete bunkers on the construction site for immediate assembly or joining only with human participation and often with scaffolding intended only for this purpose seem long outdated. Simple devices (e.g. controlled closures or protectors) have long been used - but not in construction.

The electrical supply of systems and the operating resources for the construction process do not reach the construction site, which is usually constantly changing, because assigned and secured feed points (interfaces) that are important for the protective function are necessary as power distributors, backup power generators, isolating transformers and flexible cables to protect against damage when being driven over or torn off must be laid protected. This excludes similar electrical, electronic and other controls, regulations and sometimes several hand-held power tools used in mechanical engineering.

The complicated formwork work is the most important factor in concrete construction, especially since it accounts for around a third of the shell construction costs and two thirds of the labor effort. When it comes to double-shell load-bearing walls and floor slabs, conventional construction methods fail at all except for factory-made construction.

The aim is to create a manufacturing and assembly platform for the construction site that will eliminate the above-mentioned deficiencies.

OBJECT OF THE INVENTION

It is the object of the invention to create special construction platforms for the production and assembly of floor ceilings, load-bearing walls and intermediate joining devices. They carry out several functions on the construction site, e.g. B. It serves as a reusable adjustable formwork with expanded possibilities for assembly for different width, thickness and internal openings, structure, adjustment in project position, control, etc. This platform with built-in devices can have a special place for storage on the construction site and find supplies (at least it is possible in a vertical position).

SOLUTION OF THE TASK

The task is solved according to the features of claim 1.

An advantage of this platform according to the invention is that
the maximum live load on the floor slab prescribed by building standards is greater than the total mass per unit area for the aluminum alloy platform and the load-bearing wall,
that the period for safely dismantling the platform should be as limited as possible and that it can be used multiple times within the working day if possible,
that the modular system is primarily based on maximum dimensions of approx. L = 6 m for the floor ceiling and supporting wall,
and that the storage and maintenance of this construction platform can take place on the construction site.

1. a) Herstellung und Montage von Geschossdecken,
2. b) Herstellung von monolithischen Kreuzungen zwischen Tragwänden und Geschossdecken,
3. c) Herstellung und Montage von Tragwänden.

The shell construction of buildings consists of the following stages on each floor:

1. a) Manufacture and assembly of floor ceilings,
2. b) creation of monolithic intersections between load-bearing walls and floor ceilings,
3. c) Manufacture and assembly of load-bearing walls.

The invention is explained in more detail below using exemplary embodiments which are shown in the drawings.

• 1 in Teilfiguren A, B, C, D, E, F den Aufbau von Geschossdecken; und
• 2 in Teilfiguren A, B, C, D, E weitere Einzelheiten der erfindungsgemäßen Anordnung und Verfahrensweise.

It shows:

• 1 in partial figures A, B, C, D, E, F the structure of floor slabs; and
• 2 in partial figures A, B, C, D, E further details of the arrangement and procedure according to the invention.

The compaction of fresh concrete is achieved using external vibrators for thin layers 1 and intersections 37, 39, see the 1 and 2 .

The construction platforms and their storage and maintenance arrangement on the construction site are also described first.

There are two types of platforms, one for floors, which are essentially in 1 is explained, and a second one for supporting walls, including the 2 was made.

The construction platforms for floor slabs, which are manufactured on mechanical engineering systems with increased precision for the edge elements, consist of frameworks of individual stainless profiles 8, 17, mainly made of aluminum alloys, mounted on supporting walls 13 and supports 14, which supporting structure with upper sheet 9 serves as a formwork skin when concreting, please refer 1 .

Lost U-profiles 7 are used with regular crossbars 46 ( 1 , 2B, C ) for side formwork walls when producing a floor slab as well as a corresponding intersection made of reinforced heavy concrete 37, 39 and screwing additions 40 for external intersections 39.

The light platform for floor slabs is supported with three to four supports 14 in each direction, see 1a . This enables production across the entire area. Regular sunk hook loops 15, 16 on the one hand, which were previously attached to the steel profile 3, 5, 7 or to the reinforcement 36 ( 2 B) were welded on, and a support on the other hand ensures quick and safe removal of formwork, transport and storage for freshly manufactured structures.

For assembly in the project location, either the platform with built-in devices is used before separation from the structure, or special light traverses 20 are installed between at least two hooks 19, 20 in each direction ( 1f) arranged, which can fall on upper construction surfaces.

A platform for supporting walls is subjected to less mechanical stress due to the presence of a floor slab from below on the one hand and, on the other hand, due to the way it is assembled. That's why it only contains stiffeners 25, 27, 29 to prevent impermissible shape changes. The platform for the supporting wall has sunk loop anchors 32 made of thick reinforcement within the structure and openings 28 ( 2a) for radio, computer or electrically controlled shutter 31 ( 2 B) from 32 to the lifting loop 35. Connected devices and sensors are used for adjustment in the exact project position and for control during assembly.

The ring 42 for lifting with the tower crane and rope hangers 41 are constantly on the platform ( 2d ) and are also connected to the guide roller 45 with the gripper closure 44.

The platforms are stored in a vertical position in a trench approximately 0.8 m wide at the edge of the construction site and are operated there (cleaning, maintenance, etc.). The storage area contains two rows of multiple pillars for support and guidance when moving the tower crane onto trench barriers and ladders or small elevators for operation.

The advantage is the constant length L with a variable width (or height for the supporting wall) B and the height of the ceiling H. The latter is achieved by sufficient height of the formwork sides. The basis for economical construction should be the agreement regarding the main module L for building cells with an orientation towards better patterns. Diversity for internal planning must be developed within this concept; the same applies to private houses.

Power supply to the tower crane

Electrical supply is essential for all types of controls and operating equipment, preferably without batteries.

The expansion of functions of the tower crane is based on the unhindered propagation of radio waves from the operating cabin (at least from movable cranes) and the possibilities of protected distribution of electrical power supply on the work site. To do this, you need a console (cantilever) that rotates independently around common, existing shafts, on which electrical cables connected to the network are unwound from a reel and moved to the workstation below. There it is connected to construction power distributors (AV cabinets). When it comes to short-term power, this cable can be moved from existing crane booms down to the platform, connected and transported together to the work site.

1. a) Genauigkeit von gefertigten Geschossdecken und Tragwänden.

High-quality and quick assembly of shell constructions is based on

1. a) Accuracy of manufactured floor slabs and load-bearing walls.

The platforms consist of rolled profiles and sheets that are shaped and assembled in a unique, precise manner. Your moving elements 21 ( 1e) , 34 ( 2a) are placed so close to each other and fixed in a finite position on the storage location that the tolerances as metallurgical products are maintained. To do this, there must be a low pressure of less than with large heights of fresh concrete on boundary bars (21 1 ; 25 , 27 , 28 , 2 ) contribute so that not only their shape is noticeably changed, but also the middle layer also consists of standard profiles, tiny layers of separating oil and constant checking by built-in measuring sensors to achieve agreement in the position of the platform and construction, which leads to precise adjustment before their separation, which enables the use of the above-mentioned devices and sensors.

b) Computer-controlled assembly in a finite position through numerical display of measuring sensors and guide pins installed in the tower crane on edge profiles 7.

It is worth determining the exact horizontal position of the crane boom when rotating without a load in order to then determine a suspension height without geodetic devices. Easily calculable corrections through elastic deformations of the crane boom and ropes depending on the load and the lever arm are not necessary because, with the same assembly operation, a display for the upper floor differs from the one below exactly to the bisecting position of rolled-up ropes. The trolley position on the crane boom and the rotation angle for the final position of each assembled element on a floor as well as the above-mentioned hook height should be saved in order to immediately achieve important approximations to correct information on the following floors. Only practice and perfection of tower cranes can discern the tolerances between real and predicted specifications.

c) Process-dependent binary sequence controls for closures when attaching and detaching platforms or separate structures and digital controls for adjustment to the project position during assembly.

Depending on the operating resources available during construction, mechanical, electrical, pneumatic, hydraulic and electronic controls with appropriate components and sensors can be used.

1. 1) Die mit Seilgehängen auf zwei Schleifen aufgehängte Tafel hat zwei gradlinige und eine drehende Freiheitsgrade in horizontaler Fläche, die durch Führungsstift 30 oder Führungsstifte 30 auf der Decke einerseits und entsprechender Vertiefung in der Tafel andererseits beseitigt werden kann, 2) die genaue Höhe bestimmt durch bestätigte Messung der gesamten Tafelhöhe für ein mehrschichtiges Teil und für Randprofilhöhe 7 der Geschoßdecke der numerischen Anzeige, die bei Kranbewegungen erreicht wird. Außerdem werden die Anzeigepositionen von Luftblasen auf Wasserwaagen in beiden Richtungen und Vertikalmesser benutzt, um nach Bearbeitung im Mikrocomputer zu entscheiden, ob die montierbare Konstruktion ein Mörtelbett braucht. Jedenfalls ist es sehr klein und kann mit Steuersignalen entsprechend dieser Anzeige, z. B. mit Hilfe kleiner pneumatischer Hebel unter der Plattform mit nachfolgendem Mörtelspritzen erzielt werden.

The installation of load-bearing wall panels in the project location is also based on the following requirements:

1. 1) The panel, suspended on two loops with rope hangers, has two straight and one rotating degrees of freedom in the horizontal surface, which can be eliminated by guide pin 30 or guide pins 30 on the ceiling on the one hand and a corresponding recess in the panel on the other hand, 2) the exact height is determined by confirmed measurement of the total panel height for a multi-layer part and for edge profile height 7 of the floor of the numerical display, which is achieved during crane movements. In addition, the indicating positions of air bubbles on spirit levels in both directions and vertical gauges are used to decide, after processing in the microcomputer, whether the mountable structure needs a mortar bed. In any case, it is very small and can be used with control signals according to this display, e.g. B. can be achieved with the help of small pneumatic levers under the platform with subsequent mortar spraying.

This means that remote monitoring, electrical supply and control of construction processes can be carried out from the cabin, and the storage point for the platforms can be operated.

More intelligence and modernity and the associated performance on the construction site mean a highly trained operator of the tower crane with perfection and operation at the storage point for the platform, instead of having too few qualified workers.

6. 6. The use of computers on the construction site and controlled shutters require rational (economical) construction work.

DESCRIPTION OF EXAMPLES

1. Construction

The construction of a floor slab consists of U-profiles 7, which serve as permanent formwork to separate it from the load-bearing wall, and three inner layers. The middle layer can be used in three variants - as a trapezoidal profile 3 with trapezoidal rigid foam panels 4 ( 1b) , or as steel cassette profiles 5 with insulating inserts 16 ( 1d ), or as rigid foam board 6 ( 1c ). Outer layers 1, 2 are made of lightweight concrete with reinforcement mesh. The edges of reinforcement 11 are anchored in the load-bearing wall ( 1 ). A similar composition is also favorable for light load-bearing walls that meet static and insulation requirements, with the outer wall also having a bitumen layer (38, 2 ) as moisture protection. All layers are firmly bonded together by the adhesive forces of concrete and bitumen.

2. Floor ceiling, production and assembly.

The platform for the floor ceiling is a supporting structure (truss made of aluminum profiles 8, 17), covered from above with a sheet 9 as a formwork skin. Opened from above, the formwork forms its side through supplied U-profiles 7, lost during assembly, which are fastened together with projections of the reinforcement 11 for the lower plate 1 to form boundary profiles 17 of the platform, using screws 10 ( 1b) . The U-profiles contain stiffening crossbars to which suspension loops 16 are welded.

Variable dimensions of the width B are achieved by moving separating angles 21 along transverse profiles 7 with fixation by bolts 23 through a tab 22 ( 1a) .

After smearing sheet 9 and the inner parts of the U-profile webs with separating oil and screwing them together, the formwork is prepared for concreting. The production has the following stages: concreting of the first layer of concrete, laying using construction, laying of upper reinforcement mesh and finished concreting.

Freshly manufactured construction with a distance between lifting loops 15, 16 approx. 1.5 to 2 m, is unscrewed from the platform and placed in the project position on supporting walls and on 4 to 9 mounting supports 14 ( 1A) hung up.

3. Monolithic intersection

Edge profiles 7 of the floor slab and upper surface of the underlying load-bearing wall 13 naturally form a formwork for these parts with a small height addition only for the protective layer of the reinforcement 11 ( 2 B , Section AA). For the outer wall, a screwed extension 40 is used for profile 7 ( 2c ).

4. Supporting wall, manufacturing and assembly.

The side walls of a platform for external load-bearing walls consists of 4 angles: two constant traverses 26 (welded to the formwork skin 9) with built-in approx. 3m long dimension lines (scale bars) 33 and slots 34 for a variable distance between bolts when positioning a movable one Angle 27 and removed angle 25 ( 2a) .

Here the platform for an outer wall is shown, with separating elements 24 for openings being inserted together with reinforcement for layer 1 and thus fixing it.

After smearing the inner surfaces of the platform and assembling it on the storage site, the hook loops with anchor rods 32 are placed therein through openings 28 and a lower reinforcement ( 2a, b ).

The platform for supporting walls is moved by the tower crane onto already manufactured floor slabs and placed at its edge. Its longitudinal dimension L approximately exceeds a similar platform for the floor ceiling, light distance between transverse supporting walls ( 1 ). Then the multi-layer load-bearing wall is produced in sequence.

The lower side wall 25 is removed during assembly shortly after production, the span crane is connected to the lifting loop 35 and also to the construction loop 32 using controlled locks and carefully rotated in the vertical project position, moved upwards and onto monolithic intersections (37 for inner wall, 2 , view AA) or 39 (outer wall, 2c , after screwing on attachment 40).

The adjustment in the project situation is based on the tools mentioned above. However, concrete implementation (with or without a mortar bed under the load-bearing wall) depends on the relationships between the real tolerances from practical experience and normal requirements. In 2 Two pairs of anchors 32 are shown, but this number can be increased to distribute the load more evenly.

A ring 42 for attaching tower crane hooks with 2 - 4 rope hangers 41 is placed on the storage area for lifting by hooks 43 to form loops 35 ( 2 B , 2d ) prepared and then until you return to this point after final assembly is always at the top of the platform of part 27. In 2d An alternative variant is shown, where the gripper closure 44 controlled by the tower crane 45 is attached to the shaft between guide rollers instead of a hook. The separate position for both halves is achieved by a spring. In the case of control signals, they unite and remain in this position, for example. B. by locking members or by frictional forces.

By means of crookedly positioned springs 46, a purely mechanical closure can be created under load, which is released (opened) again after the load is released ( 2e) . After the load-bearing wall has been fixed in the project position, the closure 31 is opened and the platform is separated from the structure.
