Description

Prefabricated beam and slab construction device and method

Technical Field

The present invention belongs to the technical field of bridge construction, and more specifically, particularly relates to a prefabricated beam and slab construction device and method.

Background Art

In bridge construction, the beams and slabs used in bridge construction are usually pre-prepared in advance to facilitate assembly during bridge construction and increase the speed of bridge construction. After the prefabrication of the beams and slabs, they need to be sprayed and cured to improve the appearance quality of the prefabricated beams and slabs. At the same time, it can avoid cracking and deformation of the prefabricated beams and slabs, and also avoid quality problems such as color difference and hollowing on the surface of the prefabricated beams and slabs.

The precast beam and slab spray curing device currently in use has the following problems: 1. Curing nozzles are usually set on both sides of the precast beam and slab, resulting in uneven curing on the top of the precast beam and slab; 2. Curing nozzles are generally fixedly installed and can only perform curing on the precast beam and slab once; 3. The lack of a shielding structure leads to serious water loss after the precast beam and slab is cured, which increases the number of curing times for the precast beam and slab.
