Об’єктом обстеження є збудована у 1912 р. будівля по вул. Уласа Самчука, 11, у м. Львові. На час обстеження будівля з 2014 року не експлуатується. При обстеженні дахових елементів виявлені дефекти, що можуть спричинити втрату несучої здатності нижчележачих конструктивних елементів. Решта конструкцій знаходиться в задовільному стані. На підставі технічного стану конструкцій, обстежуваний громадський будинок необхідно віднести до категорії технічного стану «3» – непридатний до нормальної експлуатації. Виявлені дефекти слід усунути при капітальному ремонті. При виконанні наведених рекомендацій та дотриманні положень про безпечну та надійну експлуатацію будівель та споруд подальша експлуатація будівлі загалом буде безпечною.

RESULTS OF TECHNICAL INSPECTION OF PUBLIC BUILDING ON ULAS SAMCHUK STREET IN LVIV

English abstract

The object of the inspection is a building on Ulas Samchuk street, 11, in Lviv – a former Felicia Boberska school for girls, built in 1912. The building with load-bearing longitudinal and transverse walls, rectangular in plan with dimensions of 30.6 x 14.05 m, with a basement and attic. On axis 1, the building is adjacent to the existing building № 3 of Lviv University of Trade and Economics. At the time of the inspection, the building has not been operated since 2014. Foundations – tape, floors above the basement – brick arches on metal beams, and concrete. Above the rest of the floors the floor is made of metal beams. The wooden covering is made in the form of a frame system with beds, racks, beams with struts made of beams and a system of rafters, the roof is made of metal sheets. The condition of load-bearing structures was determined on the basis оf the results of a detailed visual inspection and fixation of existing deformations and damage. The foundations of the building are strip, lined with brickwork of clinker bricks of pre-war firing with widening, on lime-sand mortar. Defects that would affect the bearing capacity were not detected. According to the calculation [4], the bearing capacity of the foundations is provided with a margin, even without taking into account the compaction of the soil during the long operation of the building. The technical condition of the foundations is satisfactory, they do not need repair and strengthening. During the inspection of the walls it was found that during the operation of the building there were repeated damages to the heating and sewerage system, as evidenced by traces of soaking on the walls and ceiling. accelerated wear of the walls. Destruction of balcony slabs and corrosion of metal beams along the G axis and along the 1 axis were detected. The condition of the brick load-bearing walls is classified as "2" – satisfactory, the technical condition of the balconies is classified as "3" – unsuitable for normal operation. Examination of the floor revealed no defects that would affect the load-bearing capacity. According to the calculations [4], the mezzanine and attic floors are suitable for normal further operation and perception of standard temporary loads – 2 kN/m2 (200 kgf/m2). The condition of the floor is classified as satisfactory. Wooden roof structures have suffered defects in the form of rot and soaking, the fastening of the rafters without compliance with the technology of work. The condition of wooden roof structures is unsatisfactory – the operation of structures is possible only if it is overhauled. Based on the technical condition of the structures, the inspected public building should be classified as technical condition "3" – unsuitable for normal operation.
