Description
DISPOSIÇÃO CONSTRUTIVA INTRODUZIDA EM FÔRMAS DE LAJES NERVURADASCONSTRUCTIVE PROVISION INTRODUCED IN NURVED SLAB FORMS
0 presente modelo de utilidade refere-se a uma disposição construtiva introduzida em fôrmas de lajes nervuradas, que utiliza um elemento estrutural, confeccionado em poliestireno expandido ou qualquer outro material com características equivalentes, adequado a esta finalidade, destinado à utilização em fôrmas perdidas para a execução de lajes nervuradas moldadas "in loco", o qual será capaz de propiciar a retenção do posicionamento das fôrmas, garantindo a estabilidade do conjunto, e proporcionando maior segurança para a execução da laje propriamente dita, além de reduzir o consumo de matéria prima e de mão de obra.The present utility model relates to a constructive arrangement introduced into ribbed slab formwork using a structural element made of expanded polystyrene or any other material having equivalent characteristics suitable for this purpose for use in formwork lost to execution of molded ribbed slabs "in loco", which will be able to provide retention of the positioning of the formwork, ensuring the stability of the assembly, and providing greater security for the execution of the slab itself, as well as reducing the consumption of raw material and of labor.
ANTECEDENTES DO MODELOBACKGROUND OF THE MODEL
0 emprego de lajes nervuradas em construção civil é bastante conhecido do estado da técnica, onde a conformação das nervuras é obtida pela utilização de elementos inertes, como, por exemplo, fôrmas de madeiras compostas por escoramentos de mesmo material ou metálico, sobre as quais são montadas peças de enchimento (fôrmas para lajes nervuradas) para que a laje adquira a geometria desejada, sendo que ditas fôrmas de enchimento, conhecidas popularmente de caixão perdido, são confeccionadas de diversos materiais tais como: cerâmico, madeira, blocos de concretos celulares EPS (Poliestireno Expandido). A armação das ferragens das lajes é feita manualmente através da montagem de malhas de aço, sendo que após essa etapa é feita a passagem de tubulações de elétricas e hidráulicas,e posteriormente é lançado o concreto. A cura do concreto ocorre em 28 dias, quando então é feito o descimbramento da la j e.The use of ribbed slabs in civil construction is well known in the state of the art, where rib conformation is obtained by the use of inert elements, such as wood formwork composed of shoring of the same material or metal, on which they are formed. Mounting pieces (ribbed slab formwork) are assembled so that the slab acquires the desired geometry, and said fill forms, popularly known as lost casket, are made of various materials such as: ceramic, wood, EPS cellular concrete blocks ( Expanded polystyrene). The reinforcement of the slab hardware is done manually by assembling steel mesh, and after this step is made the passage of electrical and hydraulic pipes, and later the concrete is cast. Concrete curing takes place within 28 days, when the slab is then broken up.
0 documento de Patente MU 8500775-7 ilustra um exemplo de fôrmas de lajes moldadas, onde é descrito o uso de um conjunto de lajotas de material plástico leve, preferencialmente poliestireno expandido, que irão compor as laj es com as viqas de concreto armado, formando um elemento base e um elemento de tampa, possuindo encaixes do tipo macho e fêmea em uma de suas laterais e tendo ainda entalhes na lateral oposta, para encaixe de vigotas de concreto armado, permitindo também que as tubulações (hidráulicas e elétricas) passem pelas lajotas com total facilidade, já que são construídas em material plástico que possibilita o corte.MU 8500775-7 illustrates an example of molded slab formwork, wherein the use of a set of lightweight plastic, preferably expanded polystyrene slabs, which will compose the slabs with the reinforced concrete slabs, is described. a base element and a lid element, having male and female fittings on one side and also having notches on the opposite side, for fitting reinforced concrete joists, also allowing the pipes (hydraulic and electrical) to pass through the tiles with total ease, since they are made of plastic material that allows cutting.
Nestes procedimentos, independente do material empregado, surgem diversos problemas, dentre os quais destaca-se a manutenção do posicionamento das peças de enchimento nas posições desejadas durante a concretagem, podendo ocorrer deslocamentos das referidas peças, provocando uma configuração errada da geometria traçada pelo engenheiro do calculo estrutural, como estrangulamento das nervuras de concreto armado das lajes. Este problema pode ocasionar comprometimento da resistência da estrutura, dentre outras patologias. A fixação das peças sobre a fôrma de madeira é feita, na prática, manualmente, amarrando com arames, através de pregos, utilização de espaçadores plásticos, sistemas de colagens, entre outros processos, que são demorados e despende custos adicionais commateriais, sem garantias que não ocorrerá o deslocamento das peças. Outra deficiência que se verifica na utilização dos materiais empregados para este fim, como os cerâmicos, blocos celulares e madeira, é a dificuldade na execução da passagem das tubulações elétricas e hidráulicas, que são feitas aumentando a mesa de concreto da laje, onerando o custo da obra; quando isso não é feito, a mesa de concreto da laje nervurada tem sua secção reduzida devido às passagens das ditas tubulações o que compromete a resistência da laje, provocando deformações excessivas ou até seu rompimento. Ademais, estes elementos de uma forma geral possuem alto peso próprio que dificulta o transporte nas obras verticalizadas, edifícios altos, demandando tempo e mão de obra no deslocamento destes elementos para os pavimentos superiores.In these procedures, regardless of the material used, several problems arise, among which the maintenance of the positioning of the filling parts in the desired positions during concreting is highlighted, and displacements of said parts may occur, causing a wrong configuration of the geometry drawn by the engineer. structural calculation, such as strangulation of the reinforced concrete ribs of the slabs. This problem may cause compromise of structure strength, among other pathologies. The fixation of the pieces on the wood formwork is practically done manually by tying with wires, through nails, use of plastic spacers, gluing systems, among other processes, which are time consuming and incur additional material costs, without guarantees that no displacement of parts will occur. Another deficiency in the use of materials used for this purpose, such as ceramics, cell blocks and wood, is the difficulty in performing the passage of electrical and hydraulic pipes, which are made by increasing the concrete slab table, burdening the cost. of the work; when this is not done, the ribbed slab concrete table has its section reduced due to the passage of said pipes which compromises the resistance of the slab, causing excessive deformation or even its rupture. In addition, these elements generally have a high weight of their own that makes it difficult to transport in vertical works, tall buildings, requiring time and labor to move these elements to the upper floors.
É, portanto, uma necessidade do estado da técnica proporcionar uma montagem de laje nervurada que seja segura e de fácil execução, que permita a instalação de tubulações e dutos sem a necessidade da quebra dos elementos que compõem as lajes, que causem dano estrutural ou estético à construção, que mantenham as posições das peças sem alterar a geometria da laje, e que possua características estruturais desej áveis, ou seja, resistência mecânica a esforços e cargas, de maneira a proporcionar um efeito funcional melhorado.It is therefore a necessity of the state of the art to provide a secure and easy-to-perform ribbed slab assembly that allows the installation of pipes and ducts without the need for breakage of the slab components causing structural or aesthetic damage. which maintain the positions of the parts without altering the slab geometry, and have desirable structural characteristics, ie mechanical resistance to stress and load, in order to provide an improved functional effect.
