(54) СПОСОБ ИЗГОТОВЛЕНИЯ ПЛИТЫ ПОКРЫТИЯ(54) METHOD OF MANUFACTURING A PLATE PLATE

II

Изобретение относитс к строительству и может быть использовано дл устройства кровельных покрытий повышенной степени заводской готовности из ко.мплексных панелей .The invention relates to the construction and can be used for the device of roofing of a high degree of prefabrication from complete panels.

Известен способ устройства плиты кровельного покрыти , заключающийс в изготовлении кровельного основани , например, из бетонных или теплоизол ционных панелей и нанесени гидроизол ционного сло из наплавл емого рубероида 1.A known method of arranging a roofing slab involves the manufacture of a roof base, for example, from concrete or heat insulating panels and applying a waterproofing layer of weldable roofing material 1.

Недостатком этого способа вл етс пожароопасность и снижение долговечности наплавленного сло , деструктируемого в результате применени горелок дл его расплавлени . Этот способ вл етс трудоемким и малопроизводительным.The disadvantage of this method is the fire hazard and reduction of the durability of the deposited layer, degraded by the use of burners to melt it. This method is laborious and inefficient.

Наиболее близким по технической сущности к предлагаемому изобретению вл етс способ изготовлени плиты покрыти , включающий изготовление бетонного основани и укладку на него гидроизол ционного сло из наплавл емого рубероида с предварительной обработкой последнего растворителем и последующую его прикатку 2.The closest to the technical essence of the present invention is a method of manufacturing a coating plate, including the manufacture of a concrete base and the laying on it of a waterproofing layer from the deposited roofing material with preliminary treatment of the latter with a solvent and its subsequent rolling 2.

Недостатком этого способа вл етс мала производительность труда в силу слабой степени механизации кровельных работ, трудоемкость , снижение долговечности из-за образовани пузырей.The disadvantage of this method is low labor productivity due to the low degree of mechanization of roofing, labor-intensiveness, reduced durability due to the formation of bubbles.

Цель изобретени - повышение производительности труда и качества покрыти .The purpose of the invention is to increase labor productivity and quality of the coating.

Указанна цель достигаетс тем, что согласно способу изготовлени плиты покрыти , включающему изготовление бетонного основани и укладку на него гидроизол ционного сло из наплавл емого рубероида с предва10 рительной обработкой последнего растворителем и последующую его прикатку, гидроизол ционный слой нанос т на свежеотформованное бетонное основание, после чего производ т термообработку плиты, затем произ5 вод т прикатку.This goal is achieved by the fact that, according to the method for producing a coating plate, including the manufacture of a concrete base and laying a waterproofing layer on it from a build-up roofing material with a preliminary treatment of the latter with a solvent and its subsequent rolling, the waterproofing layer is applied onto a freshly formed concrete base, after which heat treatment the slab, then produce a rolling.

Способ осуществл етс следующим образом .The method is carried out as follows.

Панели кровельного основани изготавливают формованием известным способом, т. е. заполн ют форму бетонной смесью, Roof base panels are made by molding in a known manner, i.e., the mold is filled with concrete,

20 they are tamped down, and before submission of the form into the steaming chamber, the primer wetted by a solvent is placed on the surface of the newly formed product. At the end of the usual steaming cycle, the surface of the waterproofing material is rolled. Fresh concrete mix is placed in the form, vibrated for 45 s, the deposited roofing material of the brand RM-420-1.0 or PM-500-2.0 is moistened with white spirit or technical kerosene, or lighting kerosene, or diesel fuel and wetted side laid on the surface of the concrete mix. The form is placed in a steam chamber, after being removed from which the surface of the ruberoid is rolled by a roller, providing a pressure of 0.05 MPa. 12 hours after stitching, special chips (epoxy resin with cement) are glued onto the ruberoid, the ruberoid is cut around the punch to the concrete base and the ruberoid is removed from the concrete base to determine adhesion. As a result of the tests performed, it was established that samples without rolling did not have adhesion to concrete; All samples with a rolling by the proposed method are destroyed by a layer of cardboard; samples with double rolling (the second rolling is carried out 10 minutes after the first) have no advantages over samples with single rolling. All used solvents and grades of deposited roofing material give the same effect. The use of the proposed method of roofing device provides, in comparison with the known, an increase in labor productivity, quality and durability of the coating, reduction in the labor intensity of the work as a whole, and elimination of the base priming. The economic efficiency according to preliminary calculations is 230 p. on 1000 m roof in single-layer calculus. The invention The method of manufacturing a coating plate, including the manufacture of a concrete base and laying on it of a waterproofing layer of weldable ruberoid with preliminary treatment of the latter with a solvent and its subsequent rolling, characterized in that, in order to increase the productivity of labor and quality of the coating, the waterproofing layer causes tons of newly formed concrete base, after which the slabs are heat-treated, then rolled.
