The invention aims to solve the defects in the prior art, and provides a prestressed self-compacting concrete hollow manure leaking plate to achieve the purpose of reducing the environment-friendly investment cost of a large-scale pig farm.
In order to achieve the purpose, the invention adopts the following technical scheme:
a prestressed self-compacting concrete hollow excrement-leaking plate comprises cross-shaped orthogonal longitudinal rib beams, transverse rib beams and strip-shaped excrement-leaking holes which are arranged in parallel at equal intervals; the bottom of the transverse rib beam is provided with a through trapezoidal bottom groove, the upper end of the trapezoidal bottom groove is communicated with a feces leaking hole, and the through hole part of the feces leaking hole is combined with the bottom groove to form a feces leaking channel;
the longitudinal rib beam is provided with through round holes to reduce the dead weight and facilitate demoulding and hoisting.
Specifically, the width of the upper part of the transverse section of the trapezoid bottom groove is smaller than that of the lower part of the transverse section of the trapezoid bottom groove, so that a horn mouth is formed.
Furthermore, the steel bars of the longitudinal rib beam are prestressed steel bars.
Furthermore, the longitudinal rib beam and the concrete of the longitudinal rib beam adopt self-compacting concrete.
Furthermore, male and female grooves for connection are arranged on two sides of the dung leaking plate.
The invention has the beneficial effects that:
1. because the longitudinal rib beam steel bar of the prefabricated concrete dropping leaking plate adopts the prestressed reinforcement, the rib beam concrete adopts the self-compacting concrete, and the longitudinal rib beam is provided with the through round hole, the prefabricated concrete dropping leaking plate has the advantages of light dead weight, good structural performance, simple process, low production cost and the like, and has wide market application prospect.
2. The transverse rib beam of the precast concrete dung leaking plate is provided with the trapezoidal bottom groove, so that a bottom die can be saved, the production cost is reduced, and meanwhile, the pipe drawing process is adopted during manufacturing, so that the precast concrete dung leaking plate is simple to manufacture and low in manufacturing cost.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1-3, a prestressed self-compacting concrete hollow manure leaking plate comprises cross-shaped orthogonal longitudinal rib beams 1, transverse rib beams 2 and strip-shaped manure leaking holes 3 which are arranged in parallel at equal intervals, wherein the manure leaking holes 3 in the embodiment are arranged in a 4 x 4 rectangular array, and the manure leaking holes 3 are used for discharging pig manure.
Further, the bottom of horizontal rib roof beam 2 sets up trapezoidal kerve 4 that link up, the width of the transverse section upper portion of trapezoidal kerve 4 is less than the lower part width, forms the horn mouth, 4 upper ends of trapezoidal kerve and hourglass excrement hole 3 intercommunication, the transverse section of hourglass excrement hole 3 in this embodiment is the rectangle, and 4 upper ends of trapezoidal kerve are the same with the width that leaks excrement hole 3 lower extreme, the through-hole part that leaks excrement hole 3 combines with kerve 4 to form one and goes up the wide excrement-leaking channel under the narrow, and reducible excrement and urine glues the condition in hourglass dropping board bottom.
Further, referring to fig. 4 and 5, a movable block 31 and a trapezoidal rod 41 are arranged in the mold box 8, the movable block 31 and the trapezoidal rod 41 can be separated, the shape of the movable block 31 is matched with that of the excrement leaking hole 3, and the shape of the trapezoidal rod 41 is matched with that of the trapezoidal bottom groove 4.
When the dropping board is manufactured, concrete is poured into the mold box 8, after the concrete is initially set, the trapezoidal rods 41 and the round hole pipes 5 are drawn out through a pipe drawing process, then the movable blocks 31 are knocked out from the bottom, finally the mold is dismantled, the remaining concrete blocks are the formed dropping board, the manufacturing process is simple, and the manufacturing cost is low.
Furthermore, the steel bars of the longitudinal rib beam 1 are prestressed steel bars 7, so that the bending resistance of the plate is improved, and the steel bars are saved.
