Definitions

  • the present invention relates to a method of manufacturing a wall element of masonry pieces as defined in the introduction of claim 1.
  • the present invention relates particularly to a method for manufacturing a wall element of bricks, blocks or the like masonry pieces by arranging mortar or the like binding material between essentially parallelepiped-shaped masonry pieces in order to form a monolithic structure wherein the element is assembled onto a bearing structure.
  • the present invention relates also to a structure assembled by masonry of bricks, blocks or the like essentially parallelepiped-shaped masonry pieces.
  • a brick or block wall is made on site so that a mason is brought bricks or blocks or the like masonry pieces and mortar to bind these together.
  • the mason arranges the mortar on at least one surface of the masonry piece and presses or knocks the loose piece to the already attached piece so that mortar remains in between the pieces and binds them together.
  • a scaffolding or the like stand is lifted so that the mason can get at the object of labour fairly easily.
  • Element structures where a masonry wall is assembled in industrial conditions are also familiar in structural engineering.
  • a masonry layer is affixed to the surface of a cast element for better looks and durability.
  • the masonry pieces are generally attached to said element when it is in an essentially horizontal position during the "masonry work".
  • This kind of structure will endure transportation and assembly, but as the properties and functions of the cast wall do not correspond to the masonry structure made on site, the actual masonry portion is usually just a matter of looks without any structural significance or other advantages of a masonry wall.
  • One object according to the present invention defined in this application is to provide a more effective masonry arrangement where a masonry structure is manufactured in industrial conditions.
  • Another object is to provide an arrangement where an element essentially corresponding to the masonry structure made on site can be transported and assembled at its destination safely and without the risk of breaking.
  • One further object is to provide a masonry structure arrangement where a quick assembly and erection of the building frame is attained, still utilizing structures corresponding to an ordinary masonry wall.
  • the method according to the present invention is characterized in that the lowermost structure of the element as such is arranged so that it integrally with other parts of the element constitutes a bearing structure of the element.
  • a characteristic feature of the structure according to the present invention is that its lowermost portion is arranged to constitute a strong integral portion of the element distributing the forces directed against it towards the upper portions of the element.
  • a wall element in accordance with the present invention disclosed in Figure 1 under reference 1 comprises a wall structure composed of separate masonry pieces 2, 2a, 2b, 2c constituting an integral monolithic structure.
  • the lowermost integral part of the structure is a separately formed supporting beam 3. Said beam distributes the forces directed to it especially during the handling process of the element towards the upper portions thereof.
  • a layer of mortar 4a has been used to attach the lowest actual masonry piece layer 2c to said supporting beam 3 distributing the supporting strength evenly to the element structure.
  • Said masonry pieces 2, 2a, 2b and 2c of the element have, in a way known per se in traditional masonry, been joined together with a layer of mortar 4 laid between the pieces.
  • the sectional projections 2, 3 and 4 disclose that the masonry structure as such has been favourably effected as a double structure with a layer of polyurethane or some other suitably rather hard insulation material 9 placed in between the masonry piece layers. Apart from having an insulating effect said layer 9 also acts to strengthen the structure at the same time.
  • Figure 1 discloses that a hoisting arrangement favourably is constructed so that lifting handles 5 have been brought down to the lowermost structure, suitably down to said supporting beam 3.
  • These lifting handles favourably consist of bars, cables or chains fixed temporarily or in a detachable way and their upper end favourably brought through a lifting boom 6 extending over the length of structure 1 to a lifting loop 7.
  • Figure 1 further discloses openings 8 made in the structure already in the masonry phase to provide windows, doors and the like.
  • Element 1 is suitably manufactured by applying the traditional masonry method where mortar is brought to the working site following the arrangement disclosed in Finnish patent application No. 19991075 so that mortar is induced to flow down to the object of work.
  • the element per se is favourably manufactured elsewhere than on the building site, i.e. suitably in industrial conditions and can be delivered to the site dry and in first-class shape.
  • the arrangement in accordance with the present invention considerably decreases the storing of goods on the work site.
  • Figure 2 discloses that a lowest masonry structure 1a in accordance with the present invention favourably is assembled on a footing 10 known per se and established as the lowermost structure of a building. Guiding pins 11 facilitating the alignment of the element have suitably been cast on said footing 10. Said guiding pins 11 facilitate the assembly of the lowermost structure onto said footing 10 and ensure a right alignment. A layer of assembly mortar 4a made for example on the work site is spread in between the footing 10 and the structure 1a to fix the structure 1a to said footing 10. In some cases corresponding alignment arrangements have been effected also to facilitate the mutual alignment of two overlapping elements 1, 1a (not shown).
  • a beam or a beam block 12 at the top of each element 1, 1a is suitably fitted to the upper edge of the structure.
  • Said beam or beam block 12 favourably comprises a structural casting 13 supporting e.g. a floor slab 14 or the roof structure of the building, which casting 13 is effected already at the plant.
  • the attachment of the slab 14 to the wall structure can be ensured, if necessary, with a grouting 13a.
  • one or several other structures 1 can be assembled on the lower element 1a.
  • Elements 1, 1a, disclosed in Figure 2 have been effected as a double structure with insulation material 9 fitted in between the parallel masonry pieces 2a and 2b.
  • the bearing beam structure 3a of the upper element 1 is also favourably effected as a double structure so that the beam 3a consists of two adjacent beam portions 3a' and 3a'' with insulation material 9 in between them in the same way as above.
  • adjacent beam portions 3 a' and 3 a'' have been joined together by stirrups 15 suitably made of stainless steel which stirrups 15 extend through the insulation material 9 and hold said portions 3a' and 3a'' of the bearing beam 3a in place.
  • the lowermost bearing beam 3, 3a per se is composed of masonry pieces, like favourably of lightweight aggregate concrete blocks or the like
  • a shoe 16 of e.g. profile steel extending all the way through the lower edge of the beam and suitably comprising portions 16a bent upward to increase bending rigidity, is favourably arranged to further strengthen the load-bearing capacity and rigidity of the beam 3, 3a or its portions 3a', 3a''.
  • a reinforcement 17 is placed between the layers of brick, block or the like masonry pieces as such, especially in the mortar layer 4, in a way known per se .
  • the bearing beam 3, 3a at least, is usually equipped with an additional reinforcement 17a.
  • the corresponding structure can also be applied in a case where the bearing lowermost beam 3, 3a is effected for example as concreting.
  • Figures 3 and 4 disclose how the masonry structures according to the present invention are favourably attached to each other in the corners of the building and, correspondingly, how a partitional wall or the like can be attached to the element according to the present invention.
  • protruding ribbed bar portions 18 have favourably been established on the edges of the structure.
  • adjacent elements can provisionally be joined to each other by welding together these ribbed bar portions 18 and/or by using an upright reinforcement structure as defined below.
  • the favourably protruding ribbed bar portions 18 consist of extensions 17 of the reinforcement of the wall, particularly favourably bent back to the mortar joint 4 between the masonry pieces 2 of each element to constitute the end of the protruding portion 18.
  • moulds 21, 21a can be kept ready at the work site, and when the mould 21, 21a has been assembled the upright cavities thus developed are filled on the work site e.g. by casting concrete or other hardening material into them. This is generally presented in the figure under reference number 23.
  • Figure 4 discloses how a partitional wall 1c suitably manufactured as an element according to the present invention can favourably be attached to the element in a way corresponding to a corner joint. Then a cavity 24 is favourably developed in the cross structure 1 already in the manufacturing phase and the attachment and cast can be effected in this cavity by following the above-presented principles.
