Description

Изобретение относитс к строительству и касаетс усилени бетонных стен, панелей.The invention relates to the construction and relates to the reinforcement of concrete walls and panels.
Известен способ усилени поврежденных бетонных стен, зданий путем .инъекций в трещины эпоксидных смол, обеспечивающих структурное св зывание бетона 1.There is a known method of reinforcing damaged concrete walls and buildings by injecting epoxy resins into cracks that provide structural bonding of concrete 1.
Этот способ требует специального оборудовани и не оправдан по трудозатратам и трудоемкости.This method requires special equipment and is not justified by labor costs and labor intensity.
Известен способ усилени поврежденных трещинами стен путем установки с двух сторон стены металлических конструкций, свариваемых между собой арматурными сетками с последующим бетонированием поверхностей 21 .There is a method of reinforcing cracked walls by installing metal structures on both sides of the wall, welded together by reinforcing meshes and concreting the surfaces 21.
Этот способ св зан с большими трудозатратами и вл етс металлоемким .This method is labor intensive and metal consuming.
Цель изобретени - восстановление несущей способности бетонных элементов, поврежденных трещинами.The purpose of the invention is to restore the bearing capacity of concrete elements damaged by cracks.
Указанна цель достигаетс тем, чтоперпендикул рно трещинам прорезают пазы, глубиной не более 1/3 толщины элемента и на клеющих составах в них устанавливают металлические пластины, повтор ющие форму паза.This goal is achieved by cutting slots perpendicular to the cracks, with a depth of no more than 1/3 of the thickness of the element, and metal plates that repeat the shape of the groove are installed on the adhesive compositions.
На фиг. 1 показан фрагмент бетонной стены или панели, поврежденный трещиной; на фиг. 2 - узел Г на фиг.1;на фиг.3 - разрез А-А на фиг.2.FIG. 1 shows a fragment of a concrete wall or panel damaged by a crack; in fig. 2 - the node G in figure 1; figure 3 - section aa in figure 2.
В бетонной стенке 1, повреждеТ ной трещиной 2, режущим инструментом делают пазы (прорези) 3. Длина и глу10 бина паза или прорези определ етс расчетом в зависимости от нагрузки воспринимаемой стеной или панелью. 1азы заполн ют составом 4 (например, юлимерный раствор, эпоксидный клей) In the concrete wall 1, a damaged crack 2, the grooves (slots) 3 are made with a cutting tool. The length and depth of the bin groove or slot is determined by calculation depending on the load by the perceived wall or panel. 1az filled with composition 4 (for example, a gauge solution, an epoxy adhesive)

Количество металлических пластин опреде20 л етс расчетом в зависимости от этажности и конструктивной схемы здани ..15 and place metaplastic plates 5 in them, which repeat the shape of the groove. After installation and the plates, the slits are rubbed with cement mortar. The number of metal plates is determined by calculation depending on the height and structural design of the building.
Предложенный способ усилени позвол ет полностью использовать ранее The proposed method of amplification allows full use of the previously
25 отбракованные панели и дает значительный экономический эффект.25 rejected panels and gives a significant economic effect.
