Automatic material distributing and vibrating system for concrete bridge deck slab and control method thereof

Abstract

The invention discloses an automatic material distributing and vibrating system for a concrete bridge deck slab and a control method thereof. The automatic material distributing and vibrating system comprises a track, a material distributing machine, an array type vibrating machine, a flat plate vibrating and leveling machine, a rolling film laminating machine and a control system, wherein the material distributing machine comprises a walking frame moving along the track and a material distributing hopper mounted below the walking frame; the material distributing hopper moves along a frame cross beam; the frame cross beam is parallel to the short edge of a mold; the array type vibrating machine comprises a first walking cart moving along the track and an array device mounted below a crossbeam of the first walking cart; a plurality of rows of vibrating rods are arranged below the array device in the advancing direction of the array device; the first row of vibrating rods are special dovetail joint vibrating rods arranged at intervals according to the designed dovetail joint positions; and the other rows of vibrating rods are arranged in a full-section mode and correspond to steel bar meshes. The requirement of coarse aggregate reactive powder concrete for distribution uniformity can be met, and the influence of environment changes on the bridge deck slab is reduced.

Description

technical field [0001] The invention belongs to the field of bridges, and in particular relates to an automatic material distributing and vibrating system for a concrete bridge deck and a control method thereof. Background technique [0002] At present, coarse aggregate reactive powder concrete is a new generation of cement-based material, which is characterized by high compressive strength, high tensile strength, high elastic modulus, and tensile strain hardening. It can effectively reduce the self-weight of structures when used in bridge decks, and at the same time It has high compressive strength and shear strength, which improves the durability of structures. However, the use of coarse aggregate reactive powder concrete requires high technical indicators and extremely high requirements for the distribution uniformity of steel fibers and aggregates. Traditional manual vibration or attached vibration has a greater impact on the distribution of aggregates and steel fibers; ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide an automatic concrete bridge deck distribution and vibration system to solve the problem that the pouring technology in the prior art cannot meet the requirements of steel fiber and aggregate distribution uniformity, the pouring process takes a long time, and the vibration, leveling, covering, etc. Membrane curing cannot be achieved quickly, making the bridge deck vulnerable to environmental changes
