Disclosure of Invention
The utility model aims to solve the problems that the site construction process of the cast-in-situ strip concrete foundation is complicated, the cast-in-situ strip concrete foundation cannot be reused, and the resource waste and the environmental pollution are easily caused.
The utility model provides the following technical scheme: the prefabricated spliced strip-shaped foundation is a straight strip-shaped member formed by internal reinforcement and concrete pouring, and the section of the strip-shaped foundation is rectangular; the bottom surface of the strip-shaped foundation is provided with cutting edge feet which are used for penetrating into soil to fix the strip-shaped foundation, and the top surface of the strip-shaped foundation is provided with embedded steel plates and hanging rings; the strip-shaped foundations are internally provided with preformed holes which penetrate through the body in the width direction, and the strip-shaped foundations are connected into a whole through finish rolling thread lacing wires penetrating through the preformed holes.
The internal reinforcement comprises stirrups which are arranged at intervals along the length of the stirrups in the section of the strip-shaped foundation, the stirrups are connected together in series through longitudinal ribs which are arranged on the top surface and the bottom surface, and the ends of the longitudinal ribs on the top surface and the bottom surface are bent in opposite directions.
One end of the blade foot is a screw rod, the other end of the blade foot is a cone with wide upper part and narrow lower part, and the screw rod is screwed with a reserved screw hole in the strip-shaped foundation.
Compared with the prior art, the utility model has the advantages that:
the prefabricated spliced strip foundation provided by the utility model can be prefabricated in a factory, is convenient for quality control, is quick and convenient to install on site, is energy-saving and environment-friendly, and can be reused; the problems that the bridge support strip-shaped foundation is high in construction difficulty, high in cost investment and low in construction speed and needs to be broken after construction is completed are successfully solved, in addition, the assembled concrete strip-shaped foundation can be reused, and the bridge support strip-shaped foundation belongs to an assembled component, so that the purposes of economy and practicability can be achieved.
