Abstract

The paper reports on peculiar features pertaining to execution of construction works during reconstruction of buildings. Practical experience on replacement of load-bearing structures has been analyzed for illustrative purposes. Attention has been concentrated on peculiarities in respect of organizational and technological solutions resulting from installation of temporary reinforcement structures. This is due to the fact that it is necessary to ensure spatial rigidity and stability of adjacent and existing construction structures of the building. In other words, when certain construction structures are replaced for some period of time the adjacent structures are without any support that ensure position stability for individual structural elements and building as a whole. Such a situation may lead to deformation of structures or their failure. In this regard, works must be performed in accordance with work zones that ensure stability in the adjacent structures. The paper presents examples of practical solutions concerning replacement of load-bearing floor structures and outer portion of a bearing wall in one of the buildings under constraint conditions. In this context when replacing intermediate floor works have been carried to strengthen temporarily reinforced concrete columns. Spacer steel beams providing column stability from plane have been used for this purpose. While making partial dismantling of the wall a variant presupposing installation of temporary vertical bearing structure in the form of a portal has been used in the paper. The given structure has been bearing loads from floor slab up to completion of re-bricking of bearing wall portion and arrangement of other structures in accordance with design solutions. The presented organizational and technological solutions will be useful for builders and designers while making development of design and technological documentation for reconstruction of buildings.
