Description

BUILDING METHOD AND ARRANGEMENT
TECHNICAL FIELD OF THE INVENTION
The invention relates to a building method and a building arrangement according to the preambles of the independent claims presented below. The invention relates particularly to a new way of implementing rapid and modular timber construction.
BACKGROUND OF THE INVENTION
Typically, it is slow and expensive to build durable houses of solid construction. Rapid building is normally intended for temporary use, of very light construction and does not necessarily withstand environmental conditions very well. Tent vil lages and container-type solutions cause severe waste problems when demol ished, and their sanitation is poor.
OBJECTS OF THE INVENTION
It is an object of the present invention to reduce or even completely eliminate the above-mentioned problems and disadvantages which are found in the prior art.
An object of the present invention is to provide an efficient, economical and ener gy-efficient way of implementing construction, for example timber construction.
An object of the present invention is to solve problems relating to housing shortage and rapid house building, for example, in areas affected with disasters or catastro- phes, or under difficult building conditions.
An object of the present invention is to utilize renewable construction material which is healthy, safe, and ecological.
The above presented disadvantages can be reduced or even completely elimi nated, and the above-defined objects can be attained with the present invention which is characterized in what will be defined in the characterizing parts of the independent claims presented further below.
Some embodiments according to the invention will be disclosed in the dependent claims presented further below. DESCRIPTION OF THE INVENTION
The building method according to the invention comprises at least the following steps: arranging elongated building elements, such as logs, in the form of a framework having e.g. a square or rectangular shape, on top of a construc tion base in connection with a work platform; arranging further elongated building elements on top of the framework, thereby building up a tubular construction; attaching the elongated building elements, placed on top of each other, firmly to each other; and continuing the attaching of elongated building elements until the tubular construction has a desired height.
The building method according to the invention is characterized in that the method comprises keeping the construction base first above the work platform; and
- moving the construction base down with respect to the work platform as the building work proceeds so that the distance of the top surface of the tubular construction from the work platform, i.e. the working height, is maintained between 0.5 and 2.0 m. The elongated building elements may be made of, for example, wood, plastic, a composite material, or metal, or a combination of these. Preferably, the elongated building elements are made of wood, for example logs. The elongated building elements may have a length of, for example, 2.5 to 4 m, or 3 to 3.5 m. Timber structures of different thicknesses can be used as the elongated building ele- ments, according to the conditions. The cross-sectional dimensions of the building element may be, for example, 48x98 mm. Or, if required by cold conditions, for example, the size of the building element, measured from the inside out, may be even larger, for example 48x148 mm.
The elongated building elements may be so long that one building element consti- tutes one side of the framework. The building may also be made of shorter ele ments which are attached to each other. The elongated building elements may comprise locating shapes, such as mating notches and protrusions, for example tongues and grooves. In the corners of the frameworks, it is possible to use any corner joint type of prior art, such as a dovetail joint, a feather joint, or a square joint. The elongated building elements may be attached to each other by dowel- ling, by using bolts, or by screwing, for example by screws and/or wooden dowels. Preferably, the building elements are attached by using screws and/or wooden dowels which may be installed at regular intervals or at irregular intervals between the building elements. Thus, glue is not necessarily needed at all. This secures rapid construction of good quality. In the corners of the frameworks, shorter screws or wooden dowels may be used. Techniques of joining building elements together are known as such and do not need to be described in more detail in this context.
The outer dimensions of the framework, that is, the outer dimensions of the cross- section of the finished tubular construction, in other words, the width and the height of the room to be made of it, may be, for example, 2.5 to 4 m or 3 to 3.5 m on each side. The length of the finished tubular construction, i.e. the height upon building, in other words, the length of the room to be made of it, may be, for exam ple, 5 to 9 m or 6 to 8 m. Other dimensions are feasible as well. The dimensions are determined according to the intended use.
Now, it has been found that buildings can be constructed by making tubular con structions by a method based on a simple framework structure. The tubular con struction can even be made by the single material method. In principle, the tubular construction is made of elongated building elements in the same way as a conven tional log building, layer by layer. The method of building according to the inven tion is very rapid and easy. The tubular constructions are built up in an ergonomic way in the upright position, whereby the work environment is efficient and safe. The construction base according to the invention, movable in the vertical direction, keeps the working height between 0.5 and 2.0 m, whereby it is possible to avoid the use of scaffolds and thereby to increase safety at work.
When the height of the framework is increased, a tubular construction is formed. After it has reached a desired height, the construction is turned to the horizontal direction. The sides of the framework then constitute the floor, the ceiling, and the side walls of a room. The end wall can be implemented, for example, as a window element or in the form of a plate structure made of, for example, solid wood. The tubular construction can be fitted with, for example, intermediate walls, sanitary installations, or fixtures. The tubular constructions may be built up at a factory or, for example, from a large cargo ship. The finished tubular constructions may be carried by trucks to the erection site where they are assembled to form a house, typically by using a crane. The building may comprise several storeys and be equipped with a lift or a staircase.
The method according to the invention may also be used for building other than tubular constructions, for example, for building almost any type of houses, such as wooden houses, on top of similar construction bases which are movable down.
In a method according to an embodiment of the invention, at least one lower sto rey is arranged below the work platform, and after the tubular construction has reached a desired height, the construction base and the tubular construction on top of it are moved down to the lower storey, and the tubular construction is moved off the construction base to the lower storey. The production becomes more efficient when the building materials are brought to the upper storey and the finished construction is removed from the lower storey.
The method according to the invention may also be used in case the construction base does not descend to a very low level. For example, the lower storey is not necessarily needed if a suitable space or cavity is provided under the construction base, its depth being sufficient for the downwards movement of the construction base according to the invention. Such a cavity may be, for example, the bottom cavity of an old lift shaft.
In a method according to an embodiment of the invention, the construction base and the tubular construction on top of it are moved to the height level of the work platform, and the tubular construction is moved off the construction base to the work platform. In this case, the lower storey is not necessarily needed, because the tubular construction can be removed via the work platform.
In a method according to an embodiment of the invention, after the tubular con struction has been removed from the construction base, the tubular construction is mounted in the horizontal direction so that the tubular construction constitutes the ceiling, floor, and two walls connecting the ceiling and the floor, of a building to be built, or a room in it. The tubular construction may be mounted in the horizontal direction, for example by means of a lifting apparatus and slings.
In a method according to an embodiment of the invention, the ends of the tubular constructions are closed by an element comprising a door and/or a window. Thus, the tubular construction and the elements constitute a room of a building. In a method according to an embodiment of the invention, one or more horizontally placed tubular constructions are used to construct a building whose structural frame is formed by the tubular constructions. Any other bearing structures are not necessarily needed. Thus, the tubular constructions constitute rooms in the building to be built. Several tubular constructions placed horizontally may be mounted next to and/or on top of each other to make up one larger building, whereby the tubular constructions constitute rooms in the building. The tubular constructions are like building blocks of which it is easy to design a desired building complex.
The invention also relates to a building arrangement. The building arrangement according to the invention comprises:
- a work platform, and
- a construction base provided in connection with the work platform, on top of which construction base it is possible to arrange elongated building elements, such as logs, to form a framework, and to build a tubular construction with an increasing height.
The building arrangement according to the invention is characterized in that the building arrangement comprises:
- a lift platform below the work platform, and
- first means arranged between the construction base and the lift platform, for moving the construction base with respect to the lift platform in the height direction so that distance of the top surface of the tubular construction from the work platform, i.e. the working height, is maintained between 0.5 and 2.0 m.
The building arrangement according to the invention may be placed on at least two planes, for example two storeys. The work platform is on the upper plane, such as the upper storey. A construction base is provided in connection with the work platform, for placing elongated building elements on it. The lift platform below the work platform may be, for example, on the lower storey, or between the work platform and the lower storey. The lift platform may be, for example, supported by a cable of a winch fastened to the work platform. The first means is intended for moving the construction base with respect to the lift platform in the height direction. The first means may comprise, for example, a scissor hoist or another hoist suitable for lifting and/or lowering. The hoist may be arranged between the construction base and the lift platform, for example so that the lower part of the hoist is on top of the lift platform, and the upper part is fastened to the construction base. The hoist may comprise a support, on which the construction base may be arranged. The first means may be controlled by control devices, for example from the work platform. The first means may also be remote controllable. Control devices are prior art known as such, and they will not be described in more detail in this context.
The building arrangement according to an embodiment of the invention comprises second means arranged between the work platform and the lift platform, for moving the lift platform with respect to the work platform in the height direction so that the distance of the top surface of the tubular construction from the work platform, that is, the working height, is maintained between 0.5 and 2.0 m. The second means may comprise a lift for moving the lift platform in the height direction. When the lift platform is moved with respect to the work platform in the height direction, the construction base is moved at the same time, and the working height is maintained in the desired range. The second means may be controlled by control devices, for example from the work platform. The second means may also be remote controllable. Control devices are prior art known as such, and they will not be described in more detail in this context.
The building arrangement according to an embodiment of the invention comprises a lower storey below the work platform, to which storey the construction base can be transferred for removing the tubular construction from the construction base. The production becomes more efficient when the building materials are brought to the upper storey and the finished construction is removed from the lower storey.
In the building arrangement according to an embodiment of the invention, the first means comprises a scissor hoist. The scissor hoist may be arranged on top of the lift platform. The construction base may be mounted on the upper part of the scis sor hoist or, if the upper part of the scissor hoist comprises a support, on this sup port. The scissor hoist requires little space, and it can be firmly mounted on the lift platform. The scissor hoist moves the construction base safely and evenly.
In a building arrangement according to an embodiment of the invention, the sec ond means comprises a winch connected to the work platform, the end of the winch cable being fastened to the lift platform. The winch comprises an electric motor. Preferably, the building arrangement comprises two or more winches. The end of the winch cable may be fastened to the lift platform in a detachable or stationary manner. The lift platform to be moved by the winch is simple, takes little space, and is easy to control and adjust.
The greatest advantages of the invention are cost efficiency, rapidity and the pos sibility to use renewable material, such as wood.
Strong constructions are produced by the building method according to the inven tion, applying elongated building elements. For example, a wooden building made by the method according to the invention is readily more resistant to earthquakes than many stone constructions.
Building the tubular constructions is simple and safe production line work. Unskilled labour may thus be used in the building work. Consequently, it is possi ble to provide work for local people almost anywhere, for example in a disaster area. The building according to the invention may be done manually. However, because the steps of the method are very simple, the manufacture of the tubular construction is relatively easy to automate or robotize in part or in whole.
Not many special tools, or none at all, are needed for the building work, and the building arrangement can be easily fitted in, for example, a factory, for starting the building production. The building materials can be transported as very cost effi cient cargo. There is hardly any extra air in the cargo, but the timber bundles, pos sible glass elements and bundles of solid wood boards can be tightly packed.
One advantage of the invention is that the foundation of the building can be easily made, for example, as a transferable concrete foundation.
One advantage is the ease in forming the foundation. On the building site, i.e. the lot of land, it is possible, for example, to provide merely a levelled-out gravel bed and the necessary connections for municipal engineering, such as water, drain and electric connections.
One advantage of the invention is that because the tubular constructions are very strong and relatively light in weight, it is relatively easy to move the building to a new location. The embodiment examples and advantages mentioned in this text relate, where applicable, to both the building method and the building arrangement according to the invention, even if this is not always specifically mentioned.

DETAILED DESCRIPTION OF THE DRAWING
For the sake of clarity, corresponding parts are indicated by the same reference numerals in the different figures and embodiments.
Figures 1 to 5 show a part of a building arrangement according to an embodiment of the invention. The building arrangement may be accommodated in, for example, a factory. The factory may comprise two storeys, of which the upper storey com prises a work platform 2. In connection with the work platform, a construction base 3 is provided for placing elongated building elements 1 , such as logs, on it. Figure 2 shows four wooden logs 1 placed on the construction base 3. The logs 1 are arranged in the shape of a square and fastened at the corners to form a frame- work 4. When more logs 1 are fastened on top of the framework 4, a tubular con struction 5 with an increasing height is built up on the construction base.
The building arrangement comprises a lift platform 22 below the work platform 2, as well as a scissor lift 23 arranged between the construction base 3 and the lift platform 22, for moving the construction base 3 with respect to the lift platform 22 in the height direction. The scissor lift 23 is arranged on top of the lift platform 22. The building arrangement further comprises second means arranged between the work platform 2 and the lift platform 22, for moving the lift platform 22 with respect to the work platform 2 in the height direction. The second means comprises a winch 24 which is connected to the work platform 2 and comprises an electric motor, the end of the winch cable 25 being fastened to the lift platform 22. The winch may thus be used for adjusting the height of the lift platform 22 with respect to the work platform 2. By means of the scissor lift 23 and the winch 24, the construction base 3 and the lift platform 22 are moved so that the distance of the top surface 6 of the tubular construction 5 from the work platform 2, i.e. the working height 7, is maintained between 0.5 and 2.0 m.
Figure 1 shows how the construction base 3 is first held above the work platform 2 by lifting the construction base 3 by means of the scissor lift 23 up through an opening 27 formed in the work platform 2. As the tubular construction 5 being formed on the construction base 3 increases in height, the construction base 3 is moved down as shown in Figs. 3 to 5. At first, the construction base 3 is lowered down to the lift platform 22. Then, the whole construction base 3 is gradually lowered below the work platform 2, towards the lower storey 8. In the example of the figures, the construction base 3 can be lowered almost down to the floor of the lower storey 8. As shown in Fig. 5, the finished tubular construction 5 is moved onto a wheeled base 21 which is waiting on the floor of the lower storey 8 and is used for conveying the finished tubular construction 5 further in the process.
It would be quite possible to lift the finished tubular construction 5 completely back to the upper storey, that is, to the work platform 2, and further in the process there.
After the tubular construction 5 has reached a desired height, it is transferred, for example, to a construction site 9 for a multi-storey building 10 as shown in Fig. 6. Flere, the tubular construction 5 is mounted horizontally so that it constitutes a room 11 in the building to be built. For example, the tubular construction of Fig. 2 is equipped with markings indicating which sides 1 constitute the ceiling 12, the floor 13, and the two walls 14 connecting the ceiling and the floor, in the room placed in the horizontal position. The structures of the first storey are mounted on top of a basement (not shown). The next storeys are formed by laying down tubu lar constructions to be supported by the preceding storeys. The structural frame of the building 10 can even be formed entirely of the tubular constructions 5. Figure 6 and Fig. 7 show how the ends of the tubular construction may be closed by an element 16 comprising a door and/or a window 17. The sides 1 of the tubu lar construction 5, i.e. the ceiling 12, the floor 13 and the walls 14 of the room, may be readily dimensioned to withstand a few openings. Thus, passages are formed between rooms adjacent to or on top of each other, such as corridors 18, door openings 19, staircases 20, or lift shafts (not shown).
It is obvious to a person skilled in the art that the invention is not limited merely to the above-described examples, but the invention may vary within the scope of the claims presented below. The dependent claims present some possible embodi ments of the invention, and they are, as such, not to be considered to restrict the protective scope of the invention.
