Description
Technical field
The present invention relates to building strengthening technical fields, and in particular to a kind of stone masonry house foundation ruggedized construction and method.
Background technique
Widely using rock material as house foundation in the old-fashioned masonry structure building in China's Coastal Areas, and old-fashioned room
The rubble-mound foundation in room is mostly that rubble is mixed with ordinary mortar or other low intensive cementitious materials, due to its material is loose,
The extremely low feature of globality poor, shear resistance is affected by geology hydrological environment around, geology caused by the decline of underground water
Differential settlement may cause wall crazing.In addition, the use function change in house or house carry out lotus caused by add-story reconstruction
It carries and increases.When shearing resistance resistance to compression when rubble-mound foundation is not able to satisfy requirement, it is often necessary to carry out strengthening reconstruction to rubble-mound foundation.
Traditional strengthening reconstruction mode carries out the reinforcing on basis often through the mode that Hou Bu reinforced concrete fortifield village covers, this
Reforming mode not only excavation and filling heavy workload, and it is complex to construct.
Add that enclose set processed as patent of invention that domestic applications number are CN104674680A discloses a kind of stone foundation
Journey, including former stone structure wall are made of coagulation fortifield village set, stirrup, column angle siffener angle, ground beam, the rectangular slab of stone and concrete cushion,
It is characterized in that: original structure is brick foundation, presentation quality is poor, should increase a underpinning on cleaning original structure member base
Operational procedure, conventional method are that reinforced concrete fortifield village set is added in original basis, should be arranged by design requirement in coagulation fortifield village set
Stirrup and suspension column siffener angle, coagulation fortifield village set should be formed using the concrete cast-in-situ not less than C20.The invention is attached for basis
The soil excavated volume of part is larger, and operational procedure is complicated, and coagulation fortifield village set and the globality on basis are poor, after causing reinforcing
The not high problem of underlying reli-ability.
