A slab of concrete that automatically complements the incomplete corners of stairs

Abstract

The invention relates to the technical field of concrete stairs, and discloses a slab for automatically supplementing concrete with incomplete corners of the stairs, including an outer plate and a discharge device. A slide plate is movably installed on the bottom of the outer plate, a support rod is fixedly installed on the bottom end of the slide plate, a support spring is fixedly installed on the bottom end of the slide plate, an inner plate is movably installed on the bottom end of the support rod, and the inner plate A friction plate is fixedly installed inside, a scraper is fixedly installed on the top of the friction plate, and the discharge device is movably installed inside the outer plate, and the discharge device includes a storage pipe, an extrusion device and a discharge valve. The bottom end of the material pipe is fixedly installed with a through pipe, the extruding device is movably installed inside the material storage pipe, and the discharge valve is movably installed inside the through pipe. efficiency.

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
