Abstract
A method of manufacturing paving and/or panelling modules which comprises the steps of: arranging a plurality of blocks or tesserae in a suitable template, according to a layout predefined by a locating grid of a module; cutting a piece of a layer of flexible material provided with through openings so that it matches the configuration of the module and is larger than the module; and securing through permanent securing means, the layer of flexible material to each one of the blocks or tesserae forming a module, so that they are held together by the layer with the possibility of changing their mutual inclination.
Description
- The present invention relates to a method and an apparatus for manufacturing paving and/or panelling modules.
- Paving by means of blocks or tesserae in a mosaic-like pattern is currently generally performed by manually laying a single block or tessera at a time on a sand or cement bed.
- The manner in which the individual blocks are arranged creates, as a whole, ornamental patterns which reproduce geometric shapes, e.g. an arc, a circle or a compound fan, which are repeated identically a number of times depending upon on the dimensions of the surface to be covered.
- The workers assigned to laying the blocks must then be expert in the trade, since carrying out these geometric shapes requires long working experience and a special skill in placing the individual blocks in order to obtain the best overall results, at a fair laying speed.
- A drawback of current block laying methods is therefore the fact that since they must be performed necessarily on site and by specialized personnel, they entail long production times and rather high labor costs.
- Another drawback of paving and/or panelling with current laying techniques is that any detachment of a single block and/or mosaic tessera leaves space for the adjacent elements to move and, in a relatively short time, detach, thereby compromising the integrity of the composition.
- The main object of the present invention is to provide a new method for paving and/or panelling by means of blocks or tesserae which does not necessarily involve the use of specialized labor, thereby significantly reducing its implementation costs.
- Another object of the present invention is to provide an apparatus for the mass-production of modules for street paving and/or panelling by means of which it is possible to cover larger surfaces in less time, while making the laying operation simpler and above all faster.
- Another object of the present invention is to allow mass production of a plurality of variously shaped modules which can be mutually assembled and are suitable for producing multiple ornamental patterns also for panelling sloping surfaces and vertical walls.
- Another object of the present invention is to provide modules which adapt themselves to the uneveness of the surface to be covered and ensure integrity of the finished work, thereby preventing detachment of single blocks, which would cause movement and gradual separation of adjacent blocks.
- Another object of the present invention is to provide modules which, once laid, are durable and ensure particularly extended resistance to mechanical stresses and atmospheric agents.
- Another object of the present invention is to provide a paving system which is permeable to, and capable of draining rainwater while preventing washing out of the sand from the bed.
- Another object of the present invention is to provide modules which can be easily lifted and carried by one operator.
- According to a first aspect of the present invention, there is provided a method for manufacturing paving and/or panelling modules which comprises the following operating steps:
- arranging a plurality of blocks or tesserae in a suitable template, according to a predetermined layout defined by a locating grid delimiting a module;
- cutting a piece of a layer of flexible material having through openings so as to match the configuration of said module and being of larger dimensions than said module;
- securing, by means of permanent securing means said layer of flexible material to each one of said blocks or tesserae forming said module, so that they are held together by said piece of flexible material with the possibility of changing their mutual inclination.
- Advantageously, said method, before rigidly coupling said layer to the bottom of said blocks, includes an operation of spraying and drying a primer onto the bottom of said blocks in order to promote adhesion of said coupling means.
- According to another aspect of the present invention there is provided an apparatus for performing the above method, which has a supporting frame, a plurality of workstations arranged sequentially and a conveyor which extends sequentially through said workstations, and is characterized in that it comprises at least one moving unit designed to be arranged on said conveyor to convey a module through each one of said workstations, and in that one of said workstations comprises a device for applying permanent coupling means, thereby coupling a piece of flexible material to the bottom of said module.
- Advantageously, said moving unit comprises a movable transfer tray which is designed to be arranged on said conveyor, a template supporting tray arranged to be located on said movable transfer tray, at least one reference template to be fitted on said template supporting tray and a locking cover which is designed to fix the or each reference template on said template supporting tray.
- According to another aspect of the present invention, there is provided at least one module for street paving and/or panelling which comprises at least one block or tessera, characterized in that it comprises a layer of flexible material which has through openings and permanent securing means for rigidly coupling said layer of flexible material to the or each block.
- Advantageously, said layer of flexible material provided with through openings comprises a meshed net.
- Conveniently, said module comprises two or more of said blocks or tesserae arranged according to a predetermined composition and held together by said net.

- In the accompanying drawings, identical or similar parts or components have been designated by the same reference numerals. Initially with reference to FIGS.1 to 8, reference numeral 1 indicates a generic module, the method for producing a module 1 requiring an
apparatus 2 comprising aframe 3 which supports anuninterrupted conveyor 4 arranged to move a series ofmovable units 5. - Each
movable unit 5 comprises a movable transfer tray 6, shown in FIG. 2, which is designed to slide alongguides 7 of theconveyor 4 and to support atemplate supporting tray 8, as shown in FIG. 3. - The movable transfer tray6 can be constituted by a
square platform 9 which has two straight and parallel raisedguides 11 on itsupper surface 10 and a vertical locatingpin 12 at each one of its four corners. - Each locating
pin 12 has a rack-shaped side orfront 13 and is orientated so that its rack-shaped side is directed toward the rack-shaped front of the pin located in the adjacent corner and on the same side with respect to theguides 11. - The
template supporting tray 8, shown in FIG. 3, has on itslower surface 14 two straight andparallel grooves 15 which are designed to slide, in use, along theguides 11 of the transfer tray 6. - The
template supporting plate 8 also has, at its upper surface, aperipheral rim 16 which delimits a recessedinner surface 17. - A
reference template 18, e.g. shaped as shown in FIG. 8, is arranged, in use, on the recessedsurface 17. - The
reference template 18, which can be made of aluminum, steel or plastics, has an external supportingframe 19, which is common to all kinds of template, and alocating grid 20 which instead varies according to the shape to be given to the module 1. - In the specific case shown in FIG. 8, the locating
grid 20 has a series ofribs 21 which reproduce the shape of a left module 22, shown in FIG. 7, of a composition shaped like acontrasting arc 60, shown in FIG. 6, thereby delimitingspaces 23 within which the blocks ortesserae 24, shown in FIG. 1, are to be arranged. - FIG. 4 illustrates a locking
cover 25 which is constituted by anouter border 26 delimiting acentral opening 27 which is smaller than the recessedsurface 17 of thetemplate supporting tray 8. - The
outer border 26 has, at its four corners,wider regions 28 at which there are provided throughopenings 29 arranged to act as female elements in coupling with the locating pins 12 when the lockingcover 25 is superimposed, in use, on the transfer tray 6. - On each
shoulder border 26 there is alocking device 32 of the type shown in FIG. 5, which is constituted by a pair ofrods 33 and 34 which are aligned and fitted on a respective shoulder by means ofbrackets 35 and free to perform small straight strokes lengthwise. - The
rods 33 and 34 are connected, at their ends, by aspring 36 which has a central supportingcylinder 37 which is designed to keep them at a predefined distance. - In order to use the
locking device 32 it is necessary to move therods 33 and 34 mutually closer, thus overcoming the urge of thespring 36 and, once the lockingcover 25 has been placed on thetemplate supporting tray 8, release them so that the outward ends 38 of the two wedge-shapedrods 33 and 34 interact with the rack-shapedfront 13 of the respectivefacing locating pins 12, thereby preventing any upward movement of thecover 25. - As shown in FIG. 1, a
movable unit 5 is prepared in theworkstation 40 of theapparatus 2 and is initially constituted only by the transfer tray 6 and thetemplate supporting tray 8. - An
operator 41 can thus arrange on the template supporting tray 8 areference template 18 which is suitable for providing a module such as the module 22 of FIG. 7. - The
same operator 41 can deposit theblocks 24, available incontainers 42 located in the vicinity of theworkstation 40, inside thegrid 20, by placing them with their bottom upward and trying to completely fill thespaces 23 delimited by theribs 21 that constitute thegrid 20. - After
blocks 24 have been placed on thetemplate 18, theoperator 41 can also be given the task of cleaning the bottom of theblocks 24 of any impurities that might be present. For cleaning theblocks 24 it is possible to use a rotating brush with steel bristles 43, which is located near theworkstation 40 within reach of theoperator 41. - Alternatively, the same cleaning operation can be performed by subjecting the
blocks 24 to a jet of water under pressure; in this case it is necessary to perform a subsequent drying step, e.g. by employing jets of hot air; this solution is not shown in FIG. 1. - While the
movable unit 5 is still located in theworkstation 40, aprimer 44 is advantageously sprayed onto it; said primer includes for example a petroleum resin and/or rosin applied in a solvent phase and is designed to increase bonding of an adhesive material on the bottom of theblocks 24. This operation, too, can be performed manually by theoperator 41 or by a suitable primer dispensing device (not shown in FIG. 1). - The
operator 41 then places on thetemplate 18, and therefore on theblocks 24 arranged therein, a piece of net 45 cut beforehand so as to have the same configuration as that of the module being produced and larger dimensions than said module, so as to protrude from its contour to a predetermined extent. - In order to complete the preparation of the
movable unit 5, the lockingcover 25 is arranged on thetemplate supporting tray 8, by inserting thepins 12 of the transfer tray 6 inside the throughopenings 29 of thecover 25. In this manner, theframe 26 of the lockingcover 25 locks thetemplate 18 on thetemplate supporting tray 8 owing to the twolocking devices 32. - Once the preparation of the
movable unit 5 has been completed, theoperator 41 arranges it on theinitial station 46 of theconveyor 4, which by being controlled by acontrol unit 47 transfers it sequentially through a series of workstations according to a predefined production cycle. - Preferably, the
conveyor 4, controlled by acontrol unit 47, causes a given module 1 being produced to pass through a dryingdevice 48 provided with hot air jets, not shown in FIG. 1, so as to ensure full drying of theprimer 44 and heating of the material to the temperature suitable for the subsequent glueing step. - Once the drying step is terminated, the
control unit 47 sends a control signal for the advancement of themovable unit 5 to theworkstation 49. Once themovable unit 5 has reached theworkstation 49, adevice 50 for applying permanent securing means is energized in order to rigidly secure the net 45 to the bottom of theblocks 24. - Preferably, a
dispenser 50 of an adhesive material is used which is equipped with a metering device (not shown) and is mounted on suitablemechanical arms - In this manner, adhesive material, which can be for example of the hot-melt type including EVA (Ethyl Vinyl Acetate) and synthetic resins or synthetic adhesives, is deposited at preset points upon control of the
control unit 47 and are usually distributed so as to secure the net 45 at itsnodes 54 to the bottom of theblocks 24. - Advantageously, a step is provided for drying the freshly deposited adhesive material; in this case, the module1 being produced is forwarded to another drying
device 56 e.g. provided with a series of hot air jets (not shown). - The production cycle at this points provides for the advancement of the
movable unit 5 to theworkstation 57, where anoperator 58 has the task of checking the quality of the finished product and, should the module 1 meet predefined characteristics, transferring it to aconveyor belt 59 which discharges into a store. - Transfer of the finished module1 from the
workstation 57 to theconveyor 59 can be performed manually by theoperator 58, who can overturn it in order to prepare it for the subsequent step of packaging or storage. - As shown in FIG. 7 and in FIGS.9 to 23, a generic module 1 can be composed of blocks or
tesserae 24 made of porphyry, granite or other stone-like or artificial materials. - In the specific case of module22 in FIG. 7, which illustrates the left module of a composition shaped like a
contrasting arc 60 shown in FIG. 6, it will be noted that theblocks 61 that are designed to occupy, in use, positions at the center of thecomposition 60 are larger than thelateral ones 62. - Moreover, module22 of FIG. 7 and modules shown in FIGS. 9 to 14 have a step-shaped
side 63 which is designed to delimit, in use, one of the two lateral edges of thecontrasting arc composition 60; two adjacent modules which belong to twonearby arcs 60 are thus coupled by arranging the corresponding lateral edges 63 side by side, thereby penetrating each other so as to ensure a self-locking effect in addition to uniformity of the finished work. - So far as the module22 of FIG. 7 and to those of FIGS. 9 to 13 are concerned, the lateral saw-
tooth edge 64 which is opposite to the step-shapededge 63 is constituted by an alternation ofrecesses 65 andprotrusions 67 which is studied so as to allow to combine them by interlocking in pairs, i.e., the left module 22 with theright one 68, the leftinitial module 69 with theright one 68, the rightinitial module 70 with the left one 22, the leftfinal module 71 with theright one 68, and the rightfinal module 72 with the left one 22. Thelateral module 95 of FIG. 14 instead has a straightlateral edge 96 which is opposite to the step-shaped one 63, since it acts as an element for defining the border of the surface to be covered. - If the composition is circular, like the
composition 73 shown in FIG. 15, themodule 74 of FIG. 16 is a single one and represents a quarter of a circle. Themodule 74 is constituted by a sequence of concentric circular arcs 75 formed byblocks 24 whose dimensions decrease towards the center of the circle. There is also anangular module 76 and two lateral modules, aleft one 78 and aright one 79, as shown respectively in FIGS. 17, 18 and 19. - The composition shaped like a
compound fan 80 of FIG. 20 is composed of two lateral modules, aleft one 81 as in FIG. 21 and aright one 82 as in FIG. 22, and acentral module 83 of FIG. 23. - The standard
central module 83 shown in FIG. 23 can in turn be constituted by two modules which represent, respectively, its left half 84, shown in FIG. 24, and its right half 85, shown in FIG. 25. - A second embodiment of the fan-shaped
composition 80 is constituted only by two modules, aleft one 86 and aright one 87, shown respectively in FIGS. 26 and 27, each of which already includes the left half 84 and the right half 85 of thecentral module 83, respectively. - The left and right final
prefabricated modules lateral closure modules composition 80. - The method and the apparatus for producing prefabricated modules for paving and/or panelling are susceptible of numerous modifications and variations within the scope of the protection defined by the content of the appended claims.
