Opis:
The article presents issues connected with renovating multi-storey precast concrete buildings, resulting from the consequences of construction defects occurring over the course of the building process and use of the buildings, as well as design flaws and construction defects when insulating external partitions. Analyses and conclusions which stem from them cover issues of renovation in the light of: damage in the vertical and horizontal joints, damage to the connection of layers in three-layer load-bearing and curtain walls, the effect of the damage on the possibilities of carrying out functional modernization of residential units, the effect of the damage on the effectiveness of thermo-modernization - new problems related to faulty insulation.
W artykule przedstawiono zagadnienia remontowe w budynkach wielkopłytowych wynikające ze skutków wad budowlanych powstałych w czasie budowy i eksploatacji oraz wad projektowych i wykonawczych przy realizacji docieplenia przegród zewnętrznych. Analizy i wynikające z nich wnioski obejmują zagadnienia remontowe w świetle: uszkodzeń w złączach pionowych i poziomych, uszkodzeń połączenia warstw w ścianach trójwarstwowych nośnych i osłonowych, wpływu uszkodzeń na możliwości modernizacji funkcjonalnej lokali mieszkalnych, wpływu uszkodzeń na skuteczność termomodernizacji - nowe problemy w aspekcie źle wykonanego ocieplenia.

Opis:
Vector II slab was tested on a natural scale (a slab with a dimension of 6.30 × 6.30 m) and a strip 6.30 m long and 1.20 m wide. The Vector II slab is built by precast panel 60 cm wide, 4 cm thick and 14-20 cm thick concrete overtopping on the construction site. The main purpose of the slab tests on a natural scale was to observe the "faulting" effect and temporary deflections. During the tests, the displacements in the area of the panel joints in the middle of the slab span were recorded. The maximum difference in displacement between adjacent panels of the slab model was 0.16 mm, and the vertical displacement was 1.9 mm. The strip model had no cracks that could indicate a interface cracks between the precast element and the concrete overlay. After completion of the field tests, the load was left on the slab model to verify long-term effects.

Opis:
The over 40-years-old housing stock from the industrialized mass housing era is today functionally deficient and does not meet the current needs of residents. In particular, there are numerous architectural barriers, the systems are worn and obsolete, and the number of housing types is very limited. Examples of the modernization of multi-story residential buildings (the article presents those from Russia and Ukraine) confirm that this problem is universal, and a significant improvement of the building’s. Utility value can be achieved through a relatively small modification of the building fabric: precast concrete structures of the buildings prove to be flexible enough to accommodate deep changes. The authors present a concept of modernization of a building erected in a “large block” system, typical for the Polish housing of the 1970s in many cities. The case study concerns a particular building located in Lublin in one of the large housing estates – the concept of its modernization is compatible with the local spatial development plan, the proposed solutions are architecturally coherent and technically feasible.

Opis:
The architectural form of buildings is determined by many factors, one of the most important is construction technology. It remains in a close and inseparable relationship with architectural design. Contemporary technologies in construction are constantly subject to improvements, streamlining, changes aimed at increasing all kinds of efficiency (cost, thermal efficiency, labor input, etc.). One of today's widely discussed determinants of changes in the way buildings are designed and constructed is environmental issue. An awareness of environmental degradation and climate change and their consequences prompts the search for increasingly sustainable solutions. This paper summarizes the research on prefabricated solutions and their implementation, especially in single-family residential architecture. This article presents pre-design, design, and post-design experiences related to planning and realization of single-family houses with prefabricated wall technology made of light expanded clay concrete. The authors implemented comparative qualitative and quantitative research through case studies, the method also uses experiences from their own research by design practice. The advantages and disadvantages of prefabrication in the selected technology are presented. The authors attempt to answer the question of whether the individual architectural design approach is reflected in the relevant environmental considerations, including, first, those related to the mitigation of climate change and adaptation to its consequences, and to what extent the discussed technology fits into the assumptions of climate and environmentally responsible design.
