The invention belongs to the field of building structure engineering, and relates to a gap caulking device and a caulking method.
Gaps are common in traditional and modern building structures. The gaps in traditional building structures mainly refers to the gaps between the tenon and mortise joints. Most of the traditional buildings are based on the wooden structure frame, and the wooden components are connected by mortise and tenon joints. The designed and processed tenon must be smaller than the size of the mortise to form the gap between the tenon and mortise joints in order to facilitate installation in place, especially the gap will be larger when the beam and column size are larger. In addition, the biological characteristics of wood itself make it inevitably susceptible to insects and environmental corrosion. Moreover, the gap between the tenon and the mortise will continue to expand due to the natural shrinkage of wood. There are also some gaps that need to be dealt with in modern building structures due to construction requirements, disrepair for long years and other reasons, such as ash gaps caused by the falling off of mortar in masonry structures, the gaps between column feet of prefabricated or steel structure buildings and ground, and gaps between beam-column joints and other gaps between components.
A part of the gaps have negative effects on the seismic resistance of the structure, on the one hand, they can relax the mutual constraint between the components, on the other hand, they are disadvantageous to the bearing capacity and stability of the structure or components. The traditional method of gap repair is wedge filling, but the wedge has a single function and is easy to lose, which is disadvantageous to the tolerance and earthquake resistance of the building structure.
