Flat plate for automatically complementing concrete at incomplete corners of stairs

Abstract

The invention relates to the technical field of concrete stairs, and discloses a flat plate for automatically complementing concrete at incomplete corners of stairs. The flat plate comprises outer plate bodies and a discharging device; supports are fixedly mounted on the outer sides of the outer plate bodies, grips are fixedly mounted at the top ends of the supports, sliding plates are movably mounted at the bottoms of the outer plate bodies, supporting rods are fixedly mounted at the bottom ends of the sliding plates, supporting springs are fixedly mounted at the bottom ends of the sliding plates, inner plate bodies are movably mounted at the bottom ends of the supporting rods, friction plates are fixedly mounted in the inner plate bodies, and scraping plates are fixedly mounted at the top ends of the friction plates; and the discharging device is movably mounted in the outer plate bodies, the discharging device comprises a storage pipe, an extrusion device and a discharging valve, athrough pipe is fixedly mounted at the bottom end of the storage pipe, the extrusion device is movably mounted in the storage pipe, and the discharging valve is movably mounted in the through pipe. When the flat plate is used for repairing, the concrete can be automatically complemented, so that the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of concrete stairs, in particular to a slab of concrete that automatically complements the incomplete corners of stairs. Background technique [0002] Reinforced concrete slab stairs are a kind of structural form of cast-in-place integral stairs. Because the stair section and the rest platform are cast as a whole, it is called integral staircase. The reinforced concrete slab staircase is that the entire stair section is a slab with steps placed obliquely on the upper and lower platform beams. Since the outer corners of concrete stairs are usually at right angles, and the concrete is brittle and fragile, the stair feet are prone to damage during use, and timely repairs are required to prevent accidents. The traditional repair method is to fill the concrete first. , and then use a wiper to smooth it, and then repeat the above operations to solidify the concrete at the gap. This method is time-consuming and i...

Problems solved by technology

Since the outer corners of concrete stairs are usually at right angles, and the concrete is brittle and fragile, the stair feet are prone to damage during use, and timely repairs are required to prevent accidents. The traditional repair method is to fill the concrete first. , and then use the wiper to smooth it, and then repeat the above operations to solidify the concrete at the gap. This method is time-consuming and inefficient, and it takes a long time to repair multiple damages.

[0003] Aiming at the deficiencies of the prior art, the present invention provides a slab for automatically filling in concrete at the incomplete corners of stairs, which has the advantage of automatically filling in concrete and solves the problem of time-consuming repairing
