Description

Clamping device and construction equipment

Technical Field

The utility model relates to the technical field of building construction, in particular to a clamping device and construction equipment.

Background

In the building construction process, with the improvement of the building technology level, the building structure tends to be more complicated, so that the back sills with different specifications are required to be manufactured.

In the prior art, when the back ridge is manufactured, a sickle (i.e. step by step) is usually arranged on the outer side of the die to strengthen the die. And then pouring concrete in the mould to manufacture and form the reverse ridge. Currently, the final inverted ridge is generally a rectangular inverted ridge.

However, because the sickle card that circulates on the market at present is smaller in size, when the counter-bank that the specification is great needs to be made, the sickle card can only consolidate the upper half of mould. At this time, the lower half of the die is expanded, resulting in inconsistent dimensions of the upper half and the lower half of the final inverted ridge, and unsatisfactory quality of the inverted ridge.
