Abstract
Сущность изобретени : способ усилени многопустотных плит перекрыти осуществл ют следующим образом: через отверстие в нижней полке плиты 1 в пустоту 3 ввод т арматурный стержень 2. Длину отверсти определ ют, исход из гибкости арматуры . Дл анкеровки стержн 2 и обеспечени защитного сло бетона по его длине устанавливаютс шайбы 2, наружным диаметром, превышающим диаметр стержн 2 на 5 мм. Шаг шайбгфинимаетс не менее 300 мм дл фиксации рабочего положени стержн 2 и контрол качества бетонировани по длине пустоты 3 пробивают р д отверстий 5 с шагом не более 800 мм. В каждое отверстие 5 ввод т анкерный стержень 7 гнутой формы, охватывающий арматурный стержень 2. Нижн пр молинейна часть анкера имеет резьбу. Установку стержн 2 в рабочее положение осуществл ют путем захвата его анкером 7 и закреплением анкера на поверхности нижней части плиты с помощью пластины 8 и гайки. Мелкозернистый бетон подают под давлением через отверстие 6. образованное в полу. После набора прочности бетоном анкера со стороны потолка обрезают. 3 ил. ёSUMMARY OF THE INVENTION: a method for reinforcing multi-hollow floor slabs is carried out as follows: a reinforcing bar 2 is inserted through a hole in the lower flange of a plate 1 into a void 3. The length of the hole is determined based on the flexibility of the reinforcement. To anchor the rod 2 and provide a protective layer of concrete along its length, washers 2 are installed with an outer diameter exceeding the diameter of the rod 2 by 5 mm. The puck pitch is taken at least 300 mm to fix the working position of the rod 2 and to control the quality of concreting along the length of the void 3 punch a number of holes 5 with a pitch of not more than 800 mm. A bent-shaped anchor rod 7 is inserted into each hole 5, embracing the reinforcing bar 2. The lower straight part of the anchor is threaded. The installation of the rod 2 in the working position is carried out by capturing it with the anchor 7 and fixing the anchor on the surface of the lower part of the plate using the plate 8 and a nut. Fine concrete is supplied under pressure through a hole 6. formed in the floor. After curing with concrete, the anchors are cut off from the ceiling. 3 ill. ё
