Embodiment 1
[0047] A stone masonry house foundation reinforcement structure, including a wall 1 and a stone foundation 2, the stone foundation 2 is set in the soil on the ground, the wall 1 is vertically fixed on the top surface of the stone foundation 2, and also includes Anchor rod 3, tie reinforcement 4, foundation beam 5 and exposed reinforcement 6;
[0048] A plurality of anchor rods 3 are vertically arranged in the soil on both sides of the stone foundation 2 and are perpendicular to the horizontal plane;
[0049] The tie bars 4 include wall reinforcement bars 41 and foundation reinforcement bars 42, the wall reinforcement bars 41 are horizontally installed in the lower part of the wall body 1, the foundation reinforcement bars 42 are horizontally installed in the top of the stone foundation 2, and the wall reinforcement bars 42 are horizontally installed in the upper part of the stone foundation 2. The body reinforcing bar 41 and the foundation reinforcing bar 42 correspond one to ...

The invention relates to the technical field of house reinforcing, in particular to a reinforcing structure for a stone masonry house foundation. The stone masonry house foundation comprises a wall body and a stone foundation body, and further comprises anchor rods, steel tie bars, foundation beams and exposed steel bars. According to the reinforcing structure for the stone masonry house foundation, the soil body excavation amount in the construction process is small, and even no large excavation equipment is needed; through the anchor rods driven into grooves in the two sides of the stone foundation body, the bearing capacity of the foundation body is greatly improved, and the force bearing area of the stone foundation body is increased; a force transferring path is dispersed through arrangement of the foundation beams, the total contact area between the reinforced stone foundation body and a subgrade is increased, the foundation beams and the stone foundation body bear force jointly,and the pressure borne by the stone foundation body from the wall is greatly reduced; and the foundation beams on the two sides are connected into a whole through connection of the steel tie bars, the integrity of the stone foundation body and the foundation beams is enhanced, and the situation that the loose stone foundation body deforms due to bearing overlarge stress is avoided.
Description
technical field [0001] The invention relates to the technical field of house reinforcement, in particular to a stone masonry house foundation reinforcement structure and method. Background technique [0002] Stone materials are widely used as the foundation of old masonry structures in coastal areas of my country, and the rubble foundations of old houses are mostly made of rubble mixed with ordinary mortar or other low-strength cementitious materials. The characteristics of poor performance and extremely low shear resistance are greatly affected by the surrounding geological and hydrological environment, and the uneven geological settlement caused by the decline of groundwater may lead to cracking of the wall. In addition, the change of the use function of the house or the increase of the load caused by the addition of floors to the house. When the shear and compression resistance of the rubble foundation cannot meet the requirements of use, it is often necessary to reinforc...
