Prestressed self-compacting concrete hollow dung leakage plate

Abstract

The invention discloses a prestressed self-compacting concrete hollow dung leakage plate, which comprises cross orthogonal longitudinal rib beams, transverse rib beams and strip-shaped dung leakage holes formed in parallel at equal intervals, wherein through trapezoidal bottom grooves are formed in the bottoms of the transverse rib beams; the upper ends of the trapezoidal bottom grooves are communicated with the dung leakage holes; the through hole parts of the dung leakage holes and the bottom groove are combined to form a dung leakage channel; and through round holes are formed in the longitudinal rib beams. The concrete of the longitudinal rib beams and the transverse rib beams in the prestressed self-compacting concrete hollow dung leakage plate adopts self-compacting concrete, the bottom grooves are formed in the bottom, and are manufactured by using a pipe extraction process without a bottom die. The prestressed self-compacting concrete hollow dung leakage plate has the advantages of light weight, good structural performance, simple process, low production cost and the like, and has a wide market application prospect.

Description

technical field [0001] The invention relates to a prefabricated concrete leaking manure board for large-scale pig farms, in particular to a prestressed self-compacting concrete hollow manure leaking board. Background technique [0002] With the continuous improvement of the environmental protection requirements of the breeding industry, prefabricated concrete slabs have been widely used in large-scale pig farms, but the commonly used prefabricated concrete slabs are ordinary concrete slabs produced by the vibration molding process. Plate, its equipment investment is expensive, the amount of steel bar is large, and the production cost is relatively high. Therefore, in order to reduce the production cost of concrete slabs and reduce the environmental protection investment costs of large-scale pig farms, it has become an urgent need in the market to develop a prefabricated slab with good structural performance and low production cost. Contents of the invention [0003] The o...
