Definitions

  • the present invention is applicable on building industry, consisting of a system of blocks for the construction of dividing walls.
  • Buildings represent a considerable part of the environmental impact at a global scale, a need therefore existing towards the development of products and solutions which are more environmentally friendly than those currently in use.
  • constructive solutions may be found based on new materials that privilege the use of raw-material in the manufacture thereof, thus promoting for example forest protection, and which are effective in terms of energy saving and simultaneously maintaining or even improving the current comfort standards of the user.
  • New products and construction methods may be conceived which promote a more effective power yield and a reduction of on-site building waste.
  • An example is based on the proposal of new geometries for dividing wall blocks, which represent an important percentage on the volume of building construction.
  • the first step in the assembly procedures of the wall consists in placing a guide which is laid onto the pavement with a section allowing a tongue and groove fitting with the first row of blocks.
  • the second step consists in placing square blocks on the lower corners of the wall. Subsequently, the L-shaped blocks will be placed which are combined with rectangular blocks (with framework function). The covering of the block can act as final finishing of the wall solution.
  • WO/2006/061450 claims a rectangular solid gypsum block for dividing wall construction and simultaneously the mould used for the production thereof.
  • the metal mould with a separator allows producing two blocks at the same time for manual or automatic withdrawal.
  • the block has trapezoidal tongue and groove fittings mainly on the horizontal joints. According to this document, the volume of the tongue fitting is smaller than the volume of the grove fitting. This difference cannot be excessive therefore avoiding a deviation from the guide fitting concept.
  • the bevelled trapezoidal edges aid the on-site placement of the block and, according to the description in said patent document, they avoid cracks caused by structural settlement due to construction weight. Since the block is not drilled, the placement of assemblies is therefore not foreseen.
  • CN 201176660 refers to a rectangular gypsum block with horizontal drilling. It further includes tongue and groove fitting to aid the connection on the horizontal joint.
  • the block is simplified by drillings which reduces raw-material use and translates into a final cost-effectiveness. In spite of the block having drills, the document does not indicate whether it is suitable for the settlement of any infrastructure. No reference is made to the use of mortar.
  • FR2219633 refers to a block that might be composed of any conventional material (such as gypsum or cement with fibber blend) and to the mould used for the manufacture thereof. It should be mentioned that the geometry and the fitting system of the block are very similar to those of the block disclosed in WO/2006/061450 .
  • the said block has discontinuous tongue and groove fittings with trapezoidal section on all edges of the border. Additionally to the groove fitting and so as to simplify the assembly, there are flanks with certain spacing in the tongue fittings. The bevelled trapezoidal edges simplify the on-site placement of the block.
  • the connection among blocks needs to be complemented by an adhesive material. The integration of infrastructures is not foreseen.
  • CN 201343815 refers to a gypsum monoblock for application in interior dividing walls.
  • the fitting among blocks is of the tongue and groove type, which may have different shapes, namely the shape of an arch, rectangle or trapeze. No use of mortar is mentioned to join the blocks together.
  • the block has vertical and horizontal drillings. These drillings are destined to provide a fast drying during the manufacture of the block and reduce the weight thereof.
  • ES 2170612 refers to a small gypsum panel, which may be compared to a masonry block, and is destined to the construction of non-structural walls.
  • the small panel consists of two rectangular boards with different thickness, which are joined by hardening elements (composed of flexible material) and white glue. This allows defining vertical cells, through which electrical systems may pass.
  • the constituent material of the panel is a mixture of gypsum, granulated cork, expanded polystyrene and fibreglass.
  • the thickness dissimilarity among the boards forming the double panel allows an optimal solution as far as acoustics is concerned.
  • This panel differs from that of the present invention in terms of the type of fitting among panels and particularly in terms of the inner geometry of the boards forming the double panel. In order to undertake the connection among panels the use of mortar is refrained.
  • BRMU8900518 refers to the manufacture of a pre-moulded cement block, using thick sand, cement, water and a catalyst.
  • This block is rectangular with vertical drilling and wherein two rectangular side boards stand out having a narrow thickness for fitting purposes.
  • the fittings are of the tongue and groove type having a rectangular section on the horizontal and vertical joints and which refrain from the use of plaster and mortar for settlement purposes, the use of glue being one possibility for the joining thereof.
  • the vertical drillings give way to wires, cables and piping the grooving of the wall not being needed for the passage thereof. However, this drilling type does not allow the integration of assemblies in the horizontal direction.
  • the objective of the present invention is to describe a block for the construction of dividing walls comprising two half-parts having the same geometry, each half-part having a core (2) of variable thickness consisting of alternate concave and convex curvilinear shapes (3), bevelled tongue and groove fittings (7, 8) and circular drillings for the passage of infrastructures and an outer rectangular part having constant thickness.
  • the joining of the two half-parts may be carried out by applying gypsum mortar and/or polymeric mortar on the border of the inner part (4) which consists of a continuous edge, the final block being thus formed with vertical and horizontal drilling.
  • the tongue and groove fittings (7, 8) have a trapezoidal shape the outlying points being rounded.
  • the tongue and groove fittings (7, 8) which are arranged on the vertical edge are continuous and the fittings on the horizontal edge are discontinuous.
  • the contact surfaces between the blocks at the level of the vertical and horizontal joints comprise pre-drillings for the passage of infrastructures.
  • the block for the construction of dividing walls comprises polymeric pieces for the interconnection of both half-parts.
  • an insulation is applied between the two half-parts of the block.
  • the block for the construction of dividing walls can be manufactured from gypsum composite material, black granulated cork and cloth fibbers or light concrete (with expanded clay or another light material, including black granulated cork).
  • the block for the construction of dividing walls may consist of composite material from the combination of materials considered as by-products from tire recycling industry, from cork industry and from thermal power stations.
  • the block for the construction of dividing walls may be designed with an L shape, without fittings or core (2) consisting of concave and convex shapes (3).
  • the block for the construction of dividing walls has a joint between the L-shaped block and a block of conventional shape, which is carried out by means of a metal sheet with a "groove" fitting (8) having drillings on one end, on the surface contacting the structural element so as to undertake a joining by screws.
  • the present invention consists of a block with innovative shape and geometry for dividing walls, without structural function, and adaptable to walls with resistive function.
  • the walls can be used for new construction or as a solution for rehabilitation purposes, thus being possible to manufacture the block with gypsum composite material, black granulated cork and cloth fibbers.
  • the block might also be manufactured with other materials, such as light concrete (with expanded clay or another light material, including black granulated cork), as long as being compatible with a weight allowing an easy on-site handling and with strengths associated to the non-structural functions thereof. Notwithstanding the material used, the developed solution shall always be based on the sustainability of the final solution.
  • the geometry of the constructive system of walls is based on the following objectives: (1) obtaining of a light block leading to a higher work yield; (2) simplifying the construction technology so as to produce the wall mainly as the simple assembly of fitting pieces; (3) simplifying the incorporation of the systems (electrical, communication, water supply), which generally implies the opening of holes, so as to reduce material waste (4) and improving the acoustic performance among contiguous buildings.
  • the proposed invention can be used in association with other constructive systems of structural masonry as long as focusing on the location of systems within non resistive dividing walls. Even though in this specific case of non-structural walls hole opening does not represent structural implications, it has clear influence in material waste, thus being considered as a non-rational solution for accommodating electrical systems.
  • a rectangular block is herein presented having two half-parts ( Figure 1a and Figure 1b ), which are joined by mortar or preferably a resilient material and form the final block with vertical and horizontal drilling, so as to give way to phase construction and efficient integration of infrastructures. Integration is herein understood as the forecast of the space required for infrastructure placement, causing as few material waste as possible upon installation.
  • the dimensions adopted for each half-part of the block were dependent on the maximum reasonable weight for the appropriate on-site handling and so as to obtain an appropriate working productivity thus leading to a cost-effective solution.
  • the block was proposed with a 600mm width, 300mm height and a total thickness of 140mm (connection of two half-parts with 70mm).
  • the weight is an important characteristic in terms of ergonomics and it may compromise the working productivity, which means that a clear tendency towards weight reduction of on-site handling material has been observed. Since wall construction is carried out on a segmented basis, by the in-phase laying of each half-part of the block, resulting on a wall, the reasonable weight to be handled by the worker is of 8kg. These dimensions can be varied depending on the material used and on a 150mm metrics, thus giving way to the obtaining of blocks from 450mmx300mmx140mm up to 600mmx600mmx140mm.
  • Each half-part of the block consists of an association of two parts with different shapes: an outer rectangular part with constant thickness ( Figure 1a ) and an inner part of variable thickness consisting of concave and convex curvilinear shapes (3) whose objective is to define the vertical and horizontal drilling for infrastructure accommodation ( Figure 1b ).
  • the concave parts (3) are also destined to reinforce the connection among the two half-parts and to provide the block with a monolithic behaviour. Further to the concave disks, the connection between the two half-parts of the block is carried out on the border of the inner part (4) consisting of a continuous edge ( Figure 1b ).
  • the joining between the two half-parts should be carried out with gypsum mortar used for the settlement of the blocks or, alternatively, with a polymeric mortar guaranteeing the appropriate compressive strength of both the block and the block masonry.
  • Supplementary pieces may also be used (see Figure 2 ) which simplify the connection among panels during the construction of the wall, thus contributing to wall stabilization during the construction thereof.
  • the block has along its border bevelled tongue and groove fittings (7, 8), which are continuous on the vertical joint and discontinuous on the horizontal joint.
  • the horizontal discontinuity is based on the intention of infrastructure passage. This type of fitting is destined to simplify the on-site placement of the blocks, thus increasing the efficiency of the constructive process.
  • the constructive process of the present invention comprises three phases, namely: (1) placement and laying the first face (half-part of the block) up to a height considered viable for the placement of the systems.
  • the laying is carried out with a settling material, which may be a mortar or a gypsum adhesive applied onto the horizontal joints and it is further possible to place supplementary pieces with the geometry indicated in Figure 2 , so as to simplify wall stabilization during the construction of the 2 nd wall face.
  • a dry joint is proposed for the vertical joints, benefiting from the continuous tongue and groove fittings;
  • the block has rectangular shape and is constituted by two half-parts (with similar shape and geometry) ( Figure 1a and Figure 1b ) and which are joined to form the final block with vertical and horizontal drilling ( Figure 2 ), so as to make the phase construction and the efficient integration of the infrastructures possible.
  • the inner face presents a geometry consisting of a 20mm-thick border ( Figure 1b ) and a core (2) consisting of a set of waved concave and convex surfaces (3) alternating according to a 150mm grid ( Figure 1b ).
  • the dimension of the said grid was defined based on the usual diameters of the electrical and hydraulic systems and it is destined to make the appropriate placement thereof possible.
  • the said border (4) was defined from the definition of the geometry and dimensions of the core (2) of the inner part of the block.
  • the geometry formed by convex surfaces (3) in the inner face of each half-part of the block thus forms channels for infrastructure installation, with modular and flexible design, allowing the modification of layouts and piping overlapping, when required.
  • the shape and geometry of the concave and convex surfaces (3) on the inner part of the block is determined by the diameter, curve radius and layout of the infrastructures meant for integration.
  • the block further comprises a play so as to, in case of piping layout interception, the overlapping of the pipes is made possible.
  • the continuous border (4) aims at the joining of the two half-parts of the block guaranteeing the monolithic operation of the block and assuring the laying stability among blocks, whereas the core (2) allows soothing the piece, in a process similar to drilling.
  • connection of the two half-parts of the block may be carried out by further applying gypsum mortar or a polymeric mortar (acting as resilient element) onto the concave parts (disk shape) so as to guarantee the stability of the block and walls in terms of its own weight and in terms of possible vertical loads transmitted by the flagstones.
  • joint polymeric pieces may be applied between both half-parts having the shape shown in Figure 2 so as to reinforce the connection and simplify the phase constructive process, thus ensuring a greater stability during the construction of the second wall panel.
  • the contact surfaces among the blocks at the level of the vertical and horizontal joints consist of tongue and groove fittings (7, 8) (t/g) and pre-drillings for infrastructure passage (6).
  • tongue and groove fittings aims at simplifying the assembly of the wall with an increase on the alignment rigour of the blocks, as well as reducing the amount of settling mortar. It is admissible that in some situations no bounding material is required at least on the vertical joints, the joining between blocks being therefore mainly carried out by means of the fitting effect.
  • the fittings on the horizontal edge are discontinuous along the block width so as to promote a more precise laying, which is essential to guarantee the vertical alignment of the space for the infrastructures (see Figure 1a and Figure 4a ).
  • the geometry of the tongue and groove fittings (7, 8) of the horizontal joint consists of a shape with trapezoidal section with rounded tops ( Figure 1 , Figure 4b and Figure 5 ).
  • the t/g fittings (7, 8) are 13 mm in height, 80 mm in length and have a thickness of 20 mm on its base rising up to 15 mm on the top. These dimensions were defined based on the geometric proportions of each half-part of the block, in order to provide an appropriate laying of the blocks, simplify the removing from the mould of the block and avoid right-angled edges so as to eliminate or reduce possible damages during the transportation of the blocks.
  • the vertical edges similarly present tongue and groove fittings (7, 8) and pre-drillings (6). However, unlike the horizontal edges, the t/g fittings (7, 8) of the vertical edges are continuous along the height of the block, acting as guides and as stabilizers in the assembly of the wall.
  • the trapezoidal shape and geometry of the t/g fittings (7, 8) of the vertical edges is similar to that of the fittings of the horizontal edges and the length is similar to the height of the block ( Figure 4a ).
  • the block may consist of composite material resulting from the combination of materials considered as by-products of tire recycling industry (cloth fibbers), cork industry (black granulated cork) and thermal power stations (gypsum from the desulphurisation ), for use in the construction of dividing walls.
  • the composite material will result from the combination of different percentages of gypsum (FGD) or conventional construction gypsum, black granulated cork and cloth fibbers, so as to allow obtaining an appropriate material for use in blocks for non structural purposes. If composite gypsum-based material is used, the block may be the result of a moulding process or a combined process of pressing and moulding.
  • the block will be moulded integral with the composite material.
  • the block results from blending a pressed gypsum plate with a thickness between 12 and 15 mm to a moulded composite material core (10) forming the inner shape consisting of an association of concave and convex shapes (3) as previously described ( Figure 6 ).
  • the external surface is expected to be completely flat and therefore provides a nearly final finishing.
  • the surface may be finished with a covering gypsum mortar.
  • the mixed block with pressed plate (9) and moulded nucleus (10) has an uniaxial compressive strength interval from 1,5 to 2,5 MPa, while the moulded block has a strength interval from 1,3 to 1,7 at 14 days.
  • the blocks After being removed from the mould, the blocks may be cured under room temperature conditions or under drying kiln at a temperature between 30° and 40°.
  • the constructive process intended as a simple process, is in close relationship to the preliminary objective of an efficient application of infrastructures. Therefore, the installation of a slot-rail is requested as a guide for wall implantation, and the laying of half of the wall (laying of one half of the block) benefiting from the fitting solution and the use of a settling mortar for the horizontal joints, up to the level wherein infrastructure installation is adequate.
  • the second wall panel is laid and joined to the first panel already laid by means of mortar on the border (4) and on the concave area by means of the supplementary piece shown in Figure 2 .
  • the remaining height of the wall can be formed by the simultaneous laying and connection of both half-parts of the block.
  • the wall solution may have different applications.
  • the new wall solution is based on the application of the block consisting of two half-parts, thus forming a total wall thickness of 140mm, in the case of dividing walls. Between both block halves, an insulation may be applied so as to allow a better acoustic and/or thermal performance.
  • the solution for wall rehabilitation is based on the application of mainly one half-part of the block placed with its inner face against the wall intended for rehabilitation. The thickness of this solution is of 70mm, also allowing the integration of infrastructures.
