Embodiment Construction
[0009] Such as figure 1 , figure 2 As shown, the concrete sandwich brick folded slab foundation provided by the present invention comprises a prefabricated concrete slab 1, a brick masonry 2, a cast-in-place concrete slab 3, a foundation beam 4, a steel bar bearing body 5, a sandstone cushion 6, and concrete sandwich bricks The lower part of the folded slab foundation is a prefabricated concrete slab 1, the thickness of the precast concrete slab 1 is 12 to 18 cm, the angle between the horizontal section and the oblique section of the folded slab foundation is 20 to 35 degrees, and the horizontal projection length of the oblique section of the folded slab foundation is equal to The length of the horizontal section is the same, and the brick masonry 2 is set on the precast concrete slab 1. The thickness of the brick masonry 2 is determined according to the brick modulus, which can be 12cm, 24cm, 29cm, 36cm, 48cm. Ding or three shun and one ding. A cast-in-place concrete slab ...

The invention discloses a concrete brick-sandwiched folded plate foundation. The concrete brick-sandwiched folded plate foundation is characterized in that a precast concrete plate is arranged at the lower part of the concrete brick-sandwiched folded plate foundation; a brick masonry is arranged on the precast concrete plate; a cast-in-place concrete plate is arranged on the brick masonry; a foundation beam is arranged at the crossed ridge part of two adjacent folded plates; each foundation beam and the cast-in-place concrete plate are formed by integral pouring. Steel bar force bearing bodies are arranged below the precast concrete plate in a horizontal section of the concrete brick-sandwiched folded plate foundation, a sand-gravel cushion layer is arranged on each steel bar force bearing body, each steel bar force bearing body is formed by welding three to six steel bars, the first section of each steel bar force bearing body is sharpened, and each steel bar force bearing body enters a hard soil layer. The steel bar force bearing bodies at the left and right edges of the folded plate foundation serve as electro-osmosis poles.
Description
technical field [0001] The invention relates to a concrete sandwich brick folded plate foundation, which is suitable for the field of civil engineering foundation foundation. Background technique [0002] The folded plate foundation is a new type of foundation. The folded plate foundation can convert a large amount of bending moment and shear force of the plate into axial force. However, if the folded plate is too thin, the foundation stiffness will be too low and the differential settlement will be large, and if the folded plate is too thick, it will be uneconomical. In addition, the low bearing capacity of the folded plate foundation is also an important aspect that limits its application. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a folded slab foundation for concrete with bricks, which has a relatively large thickness and relatively low manufacturing cost. [0004] For this reason, the concrete sandwich brick ...
