Definitions

• the present invention is related to a structure element called lento (lintel) which positioned above window and door frames. More ' particulary, as different from the piror art technique, the present invention is related to an isolated lento especialy for heat and sound in a sandwiched structure.
• lento In buildings, to mason a wall with bricks or structure elements to spaces which are left above doors and windows, some structure elements called lento are used to complete said spaces.
• the essential goal of using a lento is a secure substitution of wall which split the structure as iner and outer parts, having a continuation from a space of window or door.
• lentos which are needed to build a wall reliably without loading over window or door frame spaces are prepared in a wide variety.
• concrete lentos which constructed directly in its place filling the spaces of the frames. Namely, some concrete mortar is poured to a mould above a space which lentil is planned to include (door, window etc.), which is made of wood, metal or plastic and supported sufficiently from below.
• lento mould is made according to structural, achitectural and statical projects.
• the mould is arranged so that the lento has a width being the same as wall thickness and a length of 40 cm longer than that of the space which the lento is to be placed. Therefore the lento sits safely in the space above the door and window frame having a 20 cm projections in both sides to the wall sections near the space. It is obvious that realization of this method needs more time and workmanship costs.
• prefabricated lentos are included onto the structure.
• some concrete blocks of lentos which are prepared and detached from their mould in another place according to measurements taken from architectural and statical projects of the construction, are positioned so as to be a 20 cm inside of the sidewails in the place of application.
• the mould of the lento is not positioned in the place of application, additional poles and laths are not needed.
• existing some additional processes such as preparing moulds, placing metal rods, pouring concrete mortar, waiting stiffening of the mortar, watering, detaching the mould and then mounting it in application field are make this method disadvantageous.
• lento is constituted using special areated concretes. Having spaces inside, the aerated concretes are placed side by side to provide enough length. By this way, a long canal is formed. By pouring concrete mortar inside said canal, small units are combined and a mortar filled monolithic block is obtained.
• This block may be constituted as supported by poles and laths directly in a construction area or made in another place and then mounted onto the construction. Also in this method, making backfilling by pouring mortar into the spaces of aerated concrete units as combining them together is laborious and costly.
• CN101793463 patent document discloses a carrier steel plate similar to above mentioned patent.
• the invention having an H profile provides positioning to structure elements above door and window frame spaces. But it neither has an isolation property, nor exhibit enough practicality.
• An object of the present invention is to produce a lento structure element having self isolation to be used in spaces which are needed to mount doors and windows on walls during construction.
• the invention comprises an isolation region between outer sections which is obtained from stiffened mortar and an inner core which constitutes a durable section that is produced with the same process as outer sections and its all parts are as a whole in a monolithic form and inseperable
• Another object of the invention is to put forward an isolated lento production method. Accordingly, the method has following steps such as placing isolation panels which has spaces that enable to form lentos inside a mould, obtaining a raw block as pouring mortar between the panels and the lento spaces into the mould, detaching the raw block from the mould and cutting it with a specified intervals in a row such as mortar-isolation panel-lento- isolation panel-mortar and obtaining a self isolated lento structure element.
• Figure 1 shows a mould system being used to produce a heat and sound isolated lento of the invention.
• Figure 2 shows an isolated panel
• Figure 3 gives a perspective view for panels in the mould.
• Figure 4a and b depict a perspective view for upper section of the sandwich structure of the present invention.
• Lento (lintel) of the present invention is used for continuation of a wall above window and door frame spaces during construction and brings additional novelty for practical usage.
• the present invention is in the form of a sandwiched block.
• Outer sections (42) includes stiffened mortar
• inner section is a proper isolation material
• the core (middle) (41 ) of the isolation material also includes stiffened mortar.
• FIG 1 an empty mould (10) needed to produce the invention, projections (11) for fixing the isolation region as a panel (20) in to said mould (10), after mortar is poured into the mould (10) and dried enough, a mould detachment mechanism (13) for disuniting the sandwiched block from that mould and a base (12) being able to endure great forces and supporting the lower section of the mould are seen.
• the isolation panel (20) which is representing the panels to be positioned into the mould is seen.
• Said panel (20) has at least a canal (22) for fixing to the mould, corresponding to a projection above the mould wall (14).
• the canal (22) and the projection (11 ) are formed in a manner that they pass without spaces each other's respective projections to canals with a light friction.
• Said canal (22) and projection may have a cross section of the form square, rectangle, semi circle etc.
• Said projections and canals are reciprocally changed their place. That means, canals in place of projections on the mould (10) and projections in place of canals on isolation panel (20).
• the important thing here is placing the isolation panels (20) inside the mould and limiting the mortar in liquid form against forces injecting with high pressure from above the mould.
• the isolation panel (20) may have various compressed granules and also preferably have polystren and polypropilen.
• the isolation material as a single big element having a rectangular prism form, is cut with a proper cutting apparatus while providing a desired zigzag profile (23). Because of polypropilen and polystren are thermoplastic materials, they can be formed in a desired cross section as cutting with a heated wire.
• the isolation panels (20) in figure 3 are located in an empty mould (10) for preparing to mortar pouring process. Said canals (22) of the panels (20) are fixed so as to pass and lock onto the projections (1 1 ) on inner walls the mould (14) and it is provided that while pouring mortar into the spaces (31 ) between panels, the position of the panels are protected.
• Prepared mortar is poured to spaces between panels (31 ) and the core spaces (21 ) together or in an order and a sandwiched block structure is obtained.
• some amount of mortar is filled the micro spaces on the isolation panels (20) because of the force resulting from the mass of the mortar and when it got solid, a monolithic whole is provided that the mortar and the isolation panels cannot be splitted.
• the mortar is dried enough and the isolation panel (20) forms a monolithic whole, by a mould detachment mechanism (13), walls (14) of the mould are detached and the sandwiched block having the completed preparation process is moved to a place to ready for another process.
• the monolithic sandwiched block (40) is splitted into slices via cutting by a multiple cutting apparatus preferably first longitudional and then transverse.
• a multiple cutting apparatus preferably first longitudional and then transverse.
• Size of the slices may be arranged according to certain standarts or desired special dimensions by requests. Because of the cutters length, some wastages or some size differences can be obtained and even though these are in millimetric, some differences may occur between the produced lentos.
• a calibration process is applied by a proper apparatus to overcome this differences or to obtain the lirito having the most desired size and dimensions.
• a calibration apparatus having a rotating disc applies abrasion over the surface of the material to eliminate the differences. If necessary during construction, some small projections and recesses are formed over contact surfaces of the isolated lento (40) of the present invention, to a complete integration of the lento to the application surface.
• the isolated lento (40) is seen as monolithic with the application surface and it is getting a flush type appearance.
• FIG 4a an upper view and in figure 4b a perspective view of the lento (40) of the present invention is given.
• the outer layers of said lento (40) are solidified or stiffened mortar.
• the inner layer is preferably an isolation panel (20) formed from a polymer material such as polystren having inner small or micro spaces. Side surfaces of said isolation panel (20) have a zigzag form (23) to cling the layers together. Said zigzag (23) passing or clinging is preferably formed to hold the layers together but the same function can be obtained with anohter form.
• the core (41) of the panel (20) has a solidified mortar which is the same as the outer layers (42) with a rectangular cross section.
• the sandwiched block structure of the present inveniton may have various height, width and length and also can be used as a brick different from its applications.
• the present invention has a core space (21 ) to nest a more durable material like on the outer layers (42) than the isolation panel (21).
• Said core cross section may have in the form of circular, elliptic, rectangular etc.
• the core (41) may have a long continuous rectanbular cross section without interruption.
• the most important feature of the present invention is having a durable or strength material of said core (41) so that the endurance to outer forces and strength of the sandwiched structure is increased. Therefore the present invention (40) can be produced much longer than the known normal bricks or similar products and can be used as a lento above the window and the door frame spaces.
• the present invention provides that nesting a core (41) having a material being harder and denser than inner section of the isolation panel (20) makes possible to include connecting means such as screw, nail etc.without need any intermediate means such as dowel. Therefore the spaces above the door and window frames, the mountage is achieved easily.
• Disadvantages in prior art about the lentil application is overcomed with the present invention (40). So the only thing to do is placing prepared self isolated lentils (40) of the present invention to desired places. Therefore some losses such as workmanship, time etc. are compensated and heat and sound isolation is done practically by eliminating the post isolation processes of prior art technique.
