Description

Small-size manual platform of vibrating

Technical Field

The invention relates to the field of concrete pouring, in particular to a small-sized manual vibrating table.

Background

Concrete is widely applied to the field of building construction due to its excellent characteristics, and is now a name for modern buildings. The quality of the concrete placement determines to a large extent the final quality of the building and the structures. According to the national mandatory standard, all structures related to concrete construction need to be synchronously manufactured with concrete test blocks for reflecting the construction quality of the concrete structure main body. In concrete pouring construction, a construction unit needs to keep the same-condition maintenance test block besides the standard concrete maintenance test block. The common concrete standard test block is a cube block of 150mm × 150mm × 150mm, and corresponding groups of three blocks are reserved according to the number of concretes poured and different areas used. Therefore, in the construction process of a complete concrete structure, the processing and manufacturing of the concrete test block are not only large in quantity, but also frequent in operation.

Because the concrete test block is in accordance with the quality standard of the concrete building, the concrete test block should be vibrated and maintained fully in the processing and manufacturing process. Because the test block is required to be manufactured and cured under the same conditions, the test block manufacturing place must be finished at the pouring place. In actual construction, a constructor often carries the test block box to carry out on-site manufacture, and the concrete is shoveled into the test block box by using a shovel and then is simply vibrated by using reinforcing steel bars. Because the size of test block is less, utilize the reinforcing bar to carry out artifical vibration and often lead to the not closely knit test block of processing preparation, and then appear unqualified phenomena such as honeycomb pitted surface in the maintenance process. Due to the unqualified processing and manufacturing of the test block, the subsequent test data can not truly reflect the overall quality of building pouring. At present, manual vibrating platforms are not available in the market, and only electric vibrating platforms with large weights are available. The electric vibrating platform comprises complex structures such as a motor, a base and a table board, and is few small, mostly a plurality of groups of test blocks and can be vibrated simultaneously, and the electric vibrating platform is very difficult to move on a construction site due to the overlarge weight.
