Gridding information monitoring method for load transmission and deformation of wood beam and wood column

Abstract

The invention discloses a gridding information monitoring method adopted by the deformation of structural beams and column members generated in the load changing and transmitting process in the replacement and transformation process of loaded wood beams and wood columns of an old building with a masonry-timber structure. The gridding information monitoring method comprises the following steps: (1) simulating and analyzing the whole construction process and central key work procedures in advance by applying construction simulation technology; (2) vertically monitoring the stress of the beams and the columns, the displacement of the beams and the columns, the axial force of the columns, outer walls, indoor independent foundation settlement and cracks of the outer walls so as to form an organic whole, and changing dotted monitoring into gridding monitoring; and (3) comparing and linking in real time by utilizing the information data obtained through gridding monitoring and the results obtained by a mathematical model through construction simulation so as to form gridding information monitoring technology. According to the method, the deformation of a construction member between an upper structure and an adjacent space achieves the optimum point of a member controlled deformation value established by an architectural mechanical model, i.e., the point without saltation, vibration and cracks.

Description

technical field [0001] The invention relates to a construction technology of a building, in particular to a structure repair technology of an old historical building and an overall replacement technology of beams, columns and plates under the condition of using loads. During the renovation and repair process of its multi-storey brick and wood structure building, while retaining the upper floors, roofs and exterior walls that need to be used normally, the wooden floors, wooden beams, and wooden columns of the lower floors are underpinned as a whole. In order to ensure the safety of the entire building during the renovation and underpinning construction, the underpinning load transfer and deformation adopt the grid information monitoring method. Background technique [0002] Historic buildings generally refer to temples, temples, halls, buildings, pagodas, palaces, mausoleums, etc. left over from history with a long history, or some characteristic buildings where celebrities l...
