Abstract

The invention relates to a masonry block with high thermal performances using wood waste, said masonry block being used in the field of civil engineering in order to carry out structural and non-structural inner or outer walls. The claimed block has vertical hollow spaces (2) which can be filled with reinforced concrete with dispersed short fibers or longitudinal bars, and, due the way of bonding the walls and overlapping the vertical hollow spaces (2) in prefabricated blocks, uprights made of reinforced concrete evenly distributed along the length of the wall are obtained, they also having some vertical slits (3) on the longitudinal outer faces in front of the central rib or the axis of symmetry of the brick, to facilitate the splitting of the block, and some grooves (4) on the short side, for easily performing the joints between blocks along the length of the wall, thus satisfying the thermal performance requirements necessary to carry out outer walls and, at the same time, allowing the introduction of a thermal insulating layer (5) in the vertical hollow spaces.

Description

PRIN VALORIFICAREA DEȘEULUI LEMNOSBY RECOVERY OF WOOD WASTE

Invenția se referă la un bloc prefabricat de zidărie cu performanțe termice superioare prin valorificarea deșeului lemnos, utilizat în domeniul ingineriei civile, la realizarea pereților structurali și nestructurali, interiori sau exteriori.The invention relates to a prefabricated masonry block with superior thermal performance by capitalizing on wood waste, used in the field of civil engineering, for the construction of structural and non-structural walls, interior or exterior.

Deșeul lemnos se toacă obținându-se așchii din lemn cu dimensiuni mici care se mineralizează și se saturează cu apă după care se imersează în laptele de ciment. Se toarnă în matrițe și se decofrează obținându-se blocuri prefabricate evidențiate în figurile 1 și 2.The wood waste is chopped to obtain small wood chips that are mineralized and saturated with water and then immersed in cement milk. It is poured into molds and stripped to obtain prefabricated blocks highlighted in figures 1 and 2.

Particularitatea acestui bloc cu agregate ușoare provenite din deșeu lemnos, constă în existența unor goluri verticale, în care se poate turna beton armat cu bare lungi, continue sau cu armătură scurtă, dispersă, beton cel puțin clasa C12/15. Se obțin astfel montanți din beton armat, distribuiți uniform pe lungimea peretelui eliminând prezența stâlpișorilor de la intersecții sau colțuri din pereții structurali ai zidăriei confinate. în cazul blocurilor utilizate la realizarea pereților exteriori, în golurile verticale, spre partea exterioară, se va introduce și un strat termoizolator care va elimina/diminua punțile termice din elementele de anvelopa ale clădirii. Dimensiunile blocului prefabricat folosit la realizarea pereților exteriori vor păstra raportul laturilor £//=2, iar înălțimea blocului va fi de 250 de mm, grosimea nervurii exterioare este t, cea interioară de 2t, în golurile verticale, spre exterior va fi introdus un strat de termoizolație, dimensionat conform zonei climatice, iar în restul golului se va turna beton rezultând un stâlpișor cu secțiunea transversală dreptunghiulară.The peculiarity of this block with light aggregates from wood waste, consists in the existence of vertical gaps, in which it is possible to pour reinforced concrete with long, continuous bars or with short, dispersed reinforcement, concrete at least class C12 / 15. Thus, reinforced concrete uprights are obtained, evenly distributed along the length of the wall, eliminating the presence of pillars at intersections or corners in the structural walls of the confined masonry. in the case of the blocks used to make the exterior walls, in the vertical gaps, towards the exterior, a thermal insulation layer will be introduced which will eliminate / diminish the thermal bridges from the envelope elements of the building. The dimensions of the prefabricated block used to make the exterior walls will keep the ratio of the sides £ // = 2, and the height of the block will be 250 mm, the thickness of the outer rib is t, the inner 2t, in the vertical gaps, to the outside a layer will be inserted of thermal insulation, dimensioned according to the climatic zone, and in the rest of the hollow concrete will be poured resulting in a pillar with a rectangular cross section.

Avantajele pe care le oferă aceste blocuri prefabricate se referă la următoarele aspecte:The advantages offered by these prefabricated blocks refer to the following aspects:

Nu mai este necesară realizarea stâlpișorilor din structurile cu zidărie confinată, deoarece montanții din beton armat obținuți în dreptul golurilor verticale sunt distribuiți uniform pe lungimea peretelui din zidărie și participă la preluarea eforturilor în structură;It is no longer necessary to make pillars in structures with confined masonry, because the reinforced concrete uprights obtained near the vertical gaps are evenly distributed along the length of the masonry wall and participate in taking over the efforts in the structure;

Clasa de beton și diametrul sau caracteristicile barelor lungi sau a fibrelor scurte pot fi modificate în funcție de zonarea seismică și numărul de niveluri ale clădirii;The class of concrete and the diameter or characteristics of long bars or short fibers can be changed depending on the seismic zoning and the number of levels of the building;

Nu mai este necesară realizarea termoizolației suplimentare la exterior în anumite zone climatice;It is no longer necessary to make additional thermal insulation outside in certain climatic zones;

Timpul de execuție se reduce, datorită dimensiunilor mari ale blocurilor prefabricate* de manipulare data de greutatea redusă a blocurilor. / intei a 2018 00629Execution time is reduced due to the large dimensions of the prefabricated handling blocks * due to the low weight of the blocks. / inte a 2018 00629

Blocurile prefabricate vor avea caneluri (figurile 1, 2) astfel încât așezarea produselor pentru realizarea pereților în plan și pe verticală să rezulte cu abateri cât mai mici;The prefabricated blocks will have grooves (figures 1, 2) so that the placement of the products for making the walls in the plane and vertically will result with deviations as small as possible;

Blocurile prefabricate sunt concepute, astfel încât zidăria să fie execută prin țesere iar suprapunerea golurilor (figurile 3 și 4) să permită continuitatea montanților din beton armat pe verticală.The prefabricated blocks are designed so that the masonry is executed by weaving and the overlap of the gaps (figures 3 and 4) allows the continuity of the vertical reinforced concrete uprights.

Blocul prefabricat (1) cu goluri verticale (2), de formă paralelipipedică are următoarele particularități:The prefabricated block (1) with vertical gaps (2), of parallelepiped shape has the following particularities:

nervurile exterioare au grosimea egală cu t iar cea interioară de 2i;the outer ribs have a thickness equal to t and the inner one 2i;

golurile verticale se suprapun prin țeserea blocurilor prefabricate permițând obținerea unor montanți din beton armat cu fibre scurte, disperse sau cu bare longitudinale lungi, continue pe înălțimea peretelui.the vertical gaps are superimposed by weaving the prefabricated blocks allowing to obtain reinforced concrete uprights with short, dispersed fibers or with long longitudinal bars, continuous on the wall height.

pe lungimea peretelui, blocurile prefabricate se vor îmbina în sistem lambă și uluc, fiind realizate caneluri cu grosimea t/2 și lățimea egală cu 1/3;along the length of the wall, the prefabricated blocks will be joined in a tongue and groove system, being made grooves with thickness t / 2 and width equal to 1/3;

în dreptul nervurii centrale, pe fețele exterioare longitudinale, în dreptul axei de simetrie, sunt realizate șlițuri verticale care ajută la decuparea blocurilor prefabricate necesare obținerii unor elemente particulare.In the right of the central rib, on the longitudinal outer faces, in the right of the axis of symmetry, vertical slits are made which help to cut the prefabricated blocks necessary to obtain particular elements.
