Description

The invention relates to a method and a module system for building purposes as set forth in the preambles of independent claims directed thereto.

When assembling e.g. brick structures, the question is basically about using a module system, the bricks being assembled for a wall structure in one or more vertical planes by laying the same side by side with and on top of each other and by plastering the same to each other with mortar. The wall structure obtained thereby is both massive and load-bearing, such that no support is needed with various bracing members as the bricks have been laid in the wall structure in a staggered manner, i.e. with so-called offset lap joints halfway on top of each other.

A problem with the use of bricks, especially in so-called temporary or hasty construction projects, is the considerable weight of bricks and mortars, generating logistical problems especially in challenging projects such as in developing countries or catastrophic conditions, in addition to which the erection of such structures requires abundantly both manual work and water. Therefore, in practice, the use of water in demanding projects generally calls for special arrangements which are at least difficult to carry out. It is further necessary in relation to brick wall structures that other features possibly needed in a wall structure, such as heat or sound insulation, HVAC technology, internal/external cladding or the like, be implemented with superimposed extra structures separately mountable on the brick wall.

On the other hand, the module system principle is also known from e.g. LEGO or DUPLO bricks used as toy accessories, which are based on basic blocks of equal size made of plastic and attached to each other with a form locking joint present on the top and bottom surfaces thereof and implemented with a projection-recess principle.

Since the discussed blocks are only coupled to each other over the top and bottom surfaces thereof, it is necessary for sufficient stability that the structures to be assembled thereof shall be put together in the above-explained manner, with a so-called staggered brick pattern. However, constructions based on such blocks are not, even in larger sizes, applicable as such to actual building purposes because this would additionally necessitate fastening the blocks to each other by adhesive bonding, which is why the erection of wall structures, or e.g. whole buildings, would become disproportionately slow and expensive.

U.S. Pat. No. 8,671,640 further relates to a module system used for building purposes, which includes a plurality of basic components of equal size for assembling one or more wall structures in vertical plane by placing the same side by side and top of each other in connection with each other. The discussed module system comprises substantially thin-walled basic components, which are open at the lengthwise opposite ends thereof and provided with an open internal space, and which are connectible to each other side by side and on top of each other with coupling elements connectible with a form locking joint to lengthwise coupling arrangements included in each external side thereof. The discussed solution is based on a locking pin-hole arrangement bonding basic components to each other in a lengthwise direction thereof by means of coupling elements, both the mounting and, if necessary, the dismounting of which at an assembly site, or particularly on a construction site, is unduly laborious and slow.

It is an objective of the present method and module system developed for building purposes to provide a decisive improvement regarding the foregoing problems and to thereby raise substantially the prior art. In view of attaining this objective, the method and the module system of the invention are principally characterized by what is presented in the characterizing clauses of the independent claims directed thereto.

One of the most noteworthy benefits gained by a method and module system of the invention is the simplicity of the mounting of and components included in wall structures to be assembled with the module system, enabling on the one hand an extremely simple execution of logistical arrangements required by particularly demanding projects, on the one hand by virtue of the light masses of components included in the module system and, on the other hand, the assembly being carried out without tools and liquid media. Since the wall structure, consisting of the module system, includes hollow internal spaces extending continuously in superjacent basic components in a vertical direction of the wall structure, it is possible to fill the wall structure at least partially by supplying the internal spaces of the superjacent basic elements, by way of respective coupling holes included in an intermediate piece, with a filler material such as sand, an insulation material such as polyurethane, a runny binding material such as concrete, and/or the like, in addition to which the wall structure is capable of being provided with HVAC and/or sprinkler technology etc. by using intra-wall structure conduit and wire installations.

As the basic components making up the wall structure are by all sides and ends thereof in mechanical coupling with adjacent or superjacent basic elements, there will be obtained a very solid structure, in addition to which it is further possible that the wall structure assembled from basic components and end blocks with connection pieces be bonded together by means of binding elements extending in a vertical direction of the wall structure through the internal spaces thereof and respective coupling holes included in the end blocks, such as by means of steel bars capable of being twisted to a specific torsion or in a similar manner.

From the standpoint of costs, the components included in a module system of the invention provide a possibility of being manufactured in a quite affordable manner and with optimal fabrication material consumption, e.g. by means of an extruder from a plastic-based material such as e.g. polypropylene. On the other hand, the invention has major significance also from the standpoint of environmental protection as it provides a possibility of reducing significantly the waste to be disposed at a landfill site by fabricating the components included in a module system e.g. from a synthetic and/or bio-based recycled material, a reusable plastic-based material, and/or e.g. a biodegradable material which, in practice, can be synthetic or organic.

The invention relates first of all to a method for building purposes by using a module system, said module system including a plurality of mutually equal-sized basic components, which are assembled for a wall structure in one or more vertical planes by installing the same in connection with each other side by side and on top of each other. The wall structure is put together from substantially thin-walled t basic components 1, which are open at ends P thereof opposite in a lengthwise direction s and have an open internal space 1a, and which are coupled to each other side by side and on top of each other with connection pieces 2 capable of being connected with a first form locking joint L1 to lengthwise s coupling arrangements 1b present on each external side U thereof. The basic components 1 are coupled to each other, in a principle apparent e.g. from FIGS. 5a and 6, with an end block 3 interconnecting the basic components by the opposite ends P thereof and having, referring especially to FIGS. 3a-3c, one, or referring to FIGS. 4a-4c, each of its opposite external surfaces V provided with a form locking surface L2 attaching to the end faces of two or more basic components, and each of its sides with a groove 1b′ corresponding in shape to the first form locking joint L1.

In a further preferred embodiment for a method of the invention, the basic components 1 to be installed in the wall structure on top of each other are coupled to each other by mounting a connection piece 2 as shown e.g. in FIGS. 2a-2d, on a principle appearing e.g. from FIG. 5c, by its first end 2a on a top edge of the coupling arrangement 1b, such as a lengthwise s sliding groove, present on the external side U of an underlying basic component, whereby the connection piece, by reason of a stop 2b included therein, protrudes by its second end 2c above the end block 3 to be placed upon a top edge of the underlying basic component, after which the basic component to be mounted above the discussed basic component is set in position by its bottom edge by pressing its coupling arrangement 1b upon the second end 2c of the connection piece.

In a further preferred embodiment for a method of the invention, the wall structure assembled from the basic components 1 and the end blocks 3 with the connection pieces 2 is bonded together in a vertical direction h, on a principle appearing especially from FIGS. 7 and 8a, 8c, with binding elements 4 passing through the internal spaces 1a thereof and respective coupling holes 3a included in the end blocks, such as with steel bars capable of being twisted to a specific torsion or in a similar manner. The above-discussed principle is particularly evident from FIGS. 8a-8c, according to which the steel bars connected with threading to a wall structure supporting frame are twisted to a desired torsion with a nut B at the top edge thereof.

In a further preferred embodiment for a method of the invention, the wall structure assembled from the basic components 1 and the end blocks 3 with the connection pieces 2 is filled at least partially by supplying the internal spaces 1a of the superjacent basic elements, by way of the respective coupling holes 3a included in the end blocks 3, with a filler material such as sand, an insulation material such as polyurethane, a runny binding material such as concrete, and/or the like, and/or is provided with internally installed HVAC technology or the like. The above operations are capable of being easily performed on-site without needing special equipment base or machine power. FIG. 6 shows from various directions a wall section assembled as described above.

On the other hand, the invention relates also to a module system for applying the above-discussed method, said system comprising a plurality of mutually equal-sized basic components for assembling one or more wall structures in vertical plane by installing the same in connection with each other side by side and top of each other. The module system comprises, referring particularly e.g. to FIGS. 1a-1c, substantially thin-walled t basic components 1 which are open at ends thereof opposite in a lengthwise direction s and have an open internal space 1a, and which are capable of being coupled to each other, on a principle appearing e.g. from FIGS. 5a-5c and 6, side by side and on top of each other with connection pieces 2, one preferred example of which is depicted in FIGS. 2a-2d and which are capable of being connected with a first form locking joint L1 to lengthwise s coupling arrangements 1b included in each external side U thereof. The module system further includes end blocks 3, preferably of a type presented e.g. in FIGS. 3a-3c and 4a-4c, for coupling the basic components 1 to each other by opposite ends P thereof with a form locking surface L2, which is present on one (FIGS. 3a-3c) or each opposite external surface V (FIGS. 4a-4c) of the end blocks and which attaches to the end faces of two or more basic components, whereby each side of the end blocks is provided with a groove 1b′ corresponding to the first form locking joint L1. It is natural that, with respect to the side thereof opposite to the form locking surface, the topmost and/or bottommost end blocks 3 of the wall structure can be completely flat and/or without holes.

In a further preferred embodiment for a module system of the invention, referring particularly to FIGS. 2a2d, the connection piece 2 has a first end 2a, a stop 2b, and a second end 2c for coupling to each other the basic components 1, installable on top of each other in the wall structure, by mounting the connection piece's first end 2a, as presented especially in FIGS. 5a and 5b, on a top edge of the coupling arrangement 1b, such as a lengthwise s sliding groove, present on an external side U of the underlying basic component, for installing the connection piece so as to protrude by its second end 2c above an end block 3 to be placed on top of the underlying basic component's top edge, and for setting the basic component to be mounted above the underlying basic component in position by a bottom edge thereof by pressing its coupling arrangement 1b upon the connection piece's second part 2c. In this context, in a further preferred embodiment, the connection piece 2 has a length M of its stop 2b matching a thickness T of the end block 3.

In a further preferred embodiment for a module system of the invention, its basic components 1, extending in the lengthwise direction s thereof with a constant cross-section, its connection pieces 2 and/or end blocks 3 are made from a light metal, plastic, plastic- or bio-composite, ceramic material and/or an organic material.

With regard to practical logistics arrangements, the size of connection pieces is preferably such that the basic components have a cross-sectional dimension of 100 mm×100 mm and a height of 200 mm. Respectively, the end blocks 3 are preferably in practice constructed, as shown e.g. in FIGS. 3a-3c, for the coupling of six basic elements, i.e. so as to measure 600 mm. In view of various practical needs, it is possible that the cross-sectional dimensions of basic elements and the length of basic elements be varied as most appropriate for a given application.

It is obvious that the invention is not limited to the above-described or -explained embodiments but can be varied within the basic inventive concept in a multitude of ways, depending e.g. on the fabrication materials of components used in the invention at a given time. Accordingly, it is first of all evident that the components included in the module system are capable of being manufactured from a most diverse range of materials by making use of a manufacturing technique most appropriate for each application, e.g. from partially dissimilar materials, such as e.g. from plastic by injection molding or casting, from metal by casting or milling, from wood or stone by milling, etc. It is also possible to utilize the invention e.g. with a module system in which the structures of one or more connection pieces and end blocks are implemented with a single integrated connection piece or end block. On the other hand, it is also possible in the invention to utilize connection pieces without a stop, which enables adjacent basic components to be coupled by the mid-sections of the external sides. In addition, the internal space of basic components included in the module system can in terms of its cross-section be substantially other than round and/or it may comprise an internal space filling uniformly the basic component's outer circumference, such that the walls interconnecting the same and those parts that make up so-called coupling grooves are provided with holes. The components for a module system of the invention are further capable of being fabricated e.g. from a pulp material, such as paper, board pulp, coated with an appropriate material as necessary, or from some other organic material.
