Definitions

  • This invention relates to a partition-panel conceived for structuring the interior compartmentation of buildings although, in view of its special features, it may also be used for backing, as well as suspended or false ceilings. In these latter cases, it is reduced to only one of the two parts which, as we shall be seeing later, make up each panel.
  • interior partition walls dividing buildings on the inside and forming the different rooms and passageways are generally made by successively superimposing bricks, more or less light in weight, mainly of the type commonly know as hollow, laid one by one and joined together by a mortar or cement mix.
  • a very slow, laborious procedure is therefore necessary, requiring a certain skill from workers undertaking it so that the partition wall built has the correct qualities as desired.
  • the mortar or binding mix must be allowed to dry and set and further supplementary work must be performed afterwards for final finish, such as making chaces required for embedding electricity, water or any other type of utility conduit and, finally, the wall has to be plastered with layers of gypsum plaster on both sides, with which it is finished and ready for subsequent painting or decorating.
  • the partition-panel which fulfills the aforesaid requirements is the subject of this invention which, apart from comprising each and every one of the conditions mentioned is highly fire resistant (up to around 900°) and preferably made in vibrated lightweight concrete. Due to its well known properties, the latter is particularly suited to prefabricated building items.
  • the lightweight concrete subjected to this treatment includes the air which the mix has absorbed on its own plus that produced by air entraining agents which must be added to provide a spongy texture with the threefold purpose of lessening weight increasing heat/sound insulating properties and increasing its volume.
  • the air as mentioned tends to rise to the top of the mix, aided to this effect by the actual vibration itself.
  • the result is that whilst the bottom mix surface, in direct contact with the mould's surface, may look quite smooth and flat, the top surface has a rough appearance, with an infinity of tiny holes depending on the distribution of the components, according to weight and grading, and on the air bubbles tending to outcrop on this surface.
  • the top surface of the vibrated panel thus made disqualifies it for use as a partition-panel with a finish on both sides, apart from the fact that in normal vibration operations, neither is it possible to give the panel the internal through ducts we referred to earlier.
  • the solution presented by this patent consists in shaping the partition-panel by contraposing two half panels vibrated separately, checking they coincide when brought together and joining them correctly with cement-adhesive on the rough sides resulting from the vibration operations. In this ways they will bond together after the cement-adhesive's setting and a partition-panel will be obtained which, furthermore, will keep the typical rigidity of items bonded together, absorbing any possible deformation between them.
  • a framework-grill is laid on the mould's bottom.
  • Such grill is formed by a succession of long, narrow, half round members or parallel bars, with the curved surface immersed in the mix to be vibrated, thus making a corresponding succession of channels with an arch shaped cross section in the half-panel which run the whole length of the latter.
  • the half round bars of this framework are connected and assembled together to form the grill, by using a suitable number of flat cross strips. These strips are bent over at right angles at their ends which fit and adjust to the mould sides.
  • each half panel displays one flat, smooth face and a rear surface provided with a succession of longitudinal channels, arch shaped in cross section.
  • their respective channels On joining two of these half panels together back to back, their respective channels fully coincide, forming a succession of holes running through the partition-panel's whole length.
  • These channels are separated by what become the bonding ribs or areas whereby the two component parts will be bonded together into a solid, compact partition-panel.
  • one of their side edges where connection is to be made has a salient in the form of a fillet and the opposite one has a slot or recess.
  • These protuberances and recesses are trapezium shaped in cross section and are suitably sized for the salient fillets of one to penetrate the recesses of the next one, forming a groove and tongue joint.
  • This joint is improved and strengthened by the longitudinal outer channels of the panels connecting with the outside via respective slots, also longitudinal but rectangular in cross section, located in the actual edges themselves of the panel.
  • the slots in each panel facing those in the neighbouring one define a space connecting the aforementioned outer channels of both panels, enabling the ducts and communicating slot to be filled in with a cement, plaster or similar mix which, on setting, becomes a solid panel binder.
  • the two outer bars of the framework which shapes the longitudinal channels in the partition-panel have side protuberances, forming a body therewith, in the form of fillets, also longitudinal, flush with the flat side and with the same rectangular cross section, pointing toward the mould's sides.
  • the patent provides for a type of manufacture wherein the rectangular slots located in the partition-panel's edges are not completely continuous lengthwise, but occur only between regularly spaced lengths, to which effect the framework-grill's outer bars will also have rectangular protuberances spaced alternately and regularly thus forming such slots.
  • any kind of suitable, lightweight concrete can be used for making the panels we are describing.
  • the white cement type is preferable, since the panel turns out white in colour, plus, because if its good properties, a perlite aggregate to which an air entraining agent will be added to provide internal air bubbles to the effects of lessening weight and increasing insulation properties. Fibre glass or plastic reinforcement may also be added to give the panel greater bending strength in certain cases.
  • other types of chemical admixtures can be used in the mix, with different objectives that may be required like, for example, water repellent admixtures, since normal air entraining agents have a physical-mechanical action independent of the chemical reaction we want to add.
  • each lightweight concrete component will depend on the characteristics of strength, weight, insulation, etc. required to be given to the partition-panel. As an example, and with no limitation as to scope, we would hereafter describe a typical compound made of lightweight concrete containing perlite.
  • a normal process will be used, first pouring the water into a cement mixer, then the air entraining agent and cement, following with the perlite aggregate little by little. The mix is made for about 1-1/2 (one and a half) minutes until a hard plastic appearance is obtained. The result is then poured quickly into the mould to prevent possible segregation.
  • the moulding process is as follows:
  • the partition-panel consists of two parts bonded together. Therefore, moulding is carried out separately for each half panel. In this process, what is to be the visible face of the half-panel is formed on the smooth bottom of the mould.
  • the mix is poured into the mould and is spread through­out it. Vibration then begins and lasts for a time which depends on the strength, frequency of vibration and amount of mix. As a guiding example, 125 kg, centrifugal force low frequency vibrating could be used for a 2.60 ⁇ 0.60 ⁇ 0.04 half-panel, with a vibration time of some 70 seconds. So vibration may be performed by an easy combination of the strength-frequency-time magnitudes. This operation must be carried out in order to achieve not the total concrete compaction by extracting all the air bubbles possible, but simply for the latter to rise sufficiently from the bottom of the mould, i.e. from what is to be the visible face of the panel.
  • the device for performing the process basically comprises an absolutely smooth bottomed, tray type mould, preferably made in formica with a bottom stiffening structure and with their respective perimeter enclosing frames.
  • One of the latter's sides facing the lateral edges of the panel has a longitudinally protruding fillet with a trapezium shaped cross section and the other side will have a longitudinal recess with the same cross section.
  • the dimensions involved will be as required to form the aforementioned collateral tongue and groove elements between the different panels.
  • these tray moulds Prior to concrete pouring, these tray moulds are set up in a suitable manner on a conventional vibrating table which transmits the vibrations for a suitable time.
  • the bar framework constituting the mould accessory for making the channels required in the top face of the half-panel being formed has already been fitted to the sides of the aforesaid tray.
  • this framework is secured onto the sides by means of the bent over square ends of the cross strips embracing it.
  • This channel shaping framework is removed at the end of the vibrating process when the channels are sufficiently well formed and before the panel's fi­nal setting, noticeably facilitating this setting.
  • the mix can be poured onto the tray mould before placing the channel forming framework or the latter can be posi­tioned on the tray and pouring can be made through the spaces existing between the bars, with which the due concrete half-panel thickening finish is facilitated.
  • FIG. 1 shows us that the partition-panel (1) is formed by joining the half-panels (2) and (3), along the ribs or bonding areas (4) which determine the compaction of the unit.
  • Each half-panel has a succession of channels (5) along its inside which, when placed opposite each other, form a succession of longitudinal through ducts (6) of which the outer ones (7) are in contact with the outside edge of the panel through the channels or re­cesses (8) provided to facilitate bonding between panels by means of a fill mix or mortar (9) occupying the slots (8) and the longitudinal outer through ducts (7) in each half-panel.
  • This figure likewise shows us the longitudinal recesses (10) and protuberances (11) with trapezium shaped cross sections on both side edges of each half-panel. These form the tongue and groove type assembly between two adjacent panels.
  • Figure 2 shows us the setting mould where the basic, flat, totally smooth tray (12) which will preform the visible face of the half-panel can be seen, as well as the special arrangement of the sides (13) where a pro­truding fillet (14) with trapezium shaped cross section can be seen on one side and a longitudinal recess (14 ⁇ ) with the same cross section on the other. These form the tongue and groove elements for joining panels.
  • the special arrangement of the framework (15) made up of a series of half round bars, connected and held together by cross strips (16) which are bent over at their ends forming a square (17) for securing the framework (15) onto the mould's sides (13).
  • Prolongations in the fashion of fillets (18) with a rectangular cross section can also be seen in this figure. As stated earlier, these can be continuous, as seen in the drawing, or be intermittent stretches which, issuing from the lateral bars of the framework (15) and making a single body therewith, form the channels or slots (8) in the lateral edges of the partition-panels.
  • figure 3 shows the panel making device in a highly schematic way in partial perspective.
  • the device mounted on a vibrating table (19) fitted with a vibrator (20) suitably located in an appropriate position, the device transmits vibrations to the tray mould (12) fitted with a bottom stiffening structure (21) where the tongue and groove fillet (14) can be seen on one of its sides (13).
  • the positioning of the framework (15) which forms the channels made in the rear of the half-panels can just be made out too.
  • the table (19) has conventional means of articulation facilitating the formwork's striking and removal of the panel from the mould.
