Placing Device Building System and Method of Constructing a Multi-Storey Building

Abstract

A placing device (1) for placing building elements (2) in constructing a multi-storey building comprises a lifting means (4) for lifting a prefabricated building element (2), a moving means (7) for moving the placing device (1) into and out of a lower storey of the multi-storey building, the lower storey being arranged under an upper storey, a rotary means (8) for rotating the building element (2) about a normal to a floor plane of the lower storey, a vertical adjustment means (20) for vertically adjusting the building element (2), and a control means (14) for controlling the placing device (1) for placing the building element (2) according to a predetermined pattern. A building system and a method of constructing a multi-storey building are also disclosed.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a placing device for placing building elements in constructing a multi-storey building. The invention also relates to a building system for constructing a multi-storey building. The invention further relates to a method of constructing a multi-storey building, in which an upper storey is constructed and raised before a lower storey is constructed under the raised upper storey.TECHNICAL BACKGROUND[0002]Multi-storey buildings are traditionally constructed from the bottom to the top, and one of the first steps is usually to perform the foundation work. The foundation can, for example, be a slab on the ground or a basement foundation, on which the first storey (i.e. the ground floor) of the multi-storey building is constructed. Then, on top of the first storey, a second storey is built which is supported by structural concrete elements belonging to the first storey.[0003]Concrete elements are subsequently placed or cast on the...

Benefits of technology

"The present invention provides a device and system for efficiently and safely constructing multi-storey buildings. The device includes a lifting means for lifting prefabricated building elements, a moving means for moving the building element into a lower storey, a rotating means for rotating the building element, a vertical adjustment means for vertically adjusting the building element, and a control means for controlling the placing device according to a predetermined pattern. The system includes the placing device and at least two lifting devices for lifting the building element when placed according to the predetermined pattern. The invention also includes a method for constructing a multi-storey building by lifting, moving, and placing the building element in the lower storey. The invention allows for the efficient and safe construction of multi-storey buildings with reduced manual labor input and better manufacturing tolerances."

Problems solved by technology

Scaffolding and other security details are often mounted at the outside of the building, which is time-consuming and expensive but necessary to obtain a safe working environment.

A general problem of prior-art building methods is that it is often relatively time-consuming and thus expensive to construct a multi-storey building.

Furthermore, much nonproductive work is performed in the form of scaffold erecting, material handling, crane lifting and also rework due to erroneously performed working operations.

This increases the labour costs and also constitutes a source of risk for the erectors.

Another problem is that both the building and the building workers are exposed to weather, which in turn results in a number of problems.

Prior-art building methods also suffer from drawbacks such as the danger of people or objects falling from a high place, which may cause both material damage and personal injury to workers who either fall or are hit by falling objects.

A further drawback of prior-art methods of constructing multi-storey buildings is the increased risk of accidents involved in working with cranes.

Another problem of prior-art building methods is that perishable materials cannot be mounted until the building is covered and initial moisture dried out.

This leads to long construction times and high costs.

One drawback of these “reverse” building methods is that they use in-situ concrete, which demands a great deal of work on the work site.

In addition, casting concrete in situ requires much equipment, for instance, in the form of pumps and forms.

There is also a risk of casting errors leading to rework.

Another problem of casting in situ is that the concrete must dry, which increases the construction time.

Prefabricated building elements cannot be used, since the “reverse” building process makes it impossible for cranes to lift building elements into the storey which is currently being constructed as it is hidden under the storeys that are already built.
