Description

Technical Field

[0001] This utility model relates to the field of concrete curing technology, specifically to a windproof and heat-insulating curtain for concrete curing. Background Technology

[0002] The widespread application of cast-in-place concrete technology in the construction of large-volume underground structures in municipal engineering has exposed many prominent problems affecting project quality. In enclosed spaces such as deep-buried underground passages and integrated utility tunnels, the temperature imbalance caused by the heat of hydration after the pouring of large-volume concrete is particularly significant. Premature release of temperature stress can interfere with the normal process of cement hydration. More seriously, the network of temperature cracks provides channels for groundwater seepage, leading to the failure of the structure's self-waterproofing system.

[0003] Windproof and heat-insulating curtains are commonly used during concrete curing to ensure proper curing conditions. However, in confined spaces such as underground passages, the placement of these curtains often clashes significantly with construction flow. Traditional suspended curing curtains typically use welded angle steel frames to support multi-layered geotextile structures. This space encroachment directly obstructs worker access during construction. Furthermore, at critical points such as emergency evacuation routes and equipment hoisting openings, the curtain support system conflicts with the turning space of construction machinery, impacting construction quality. Utility Model Content

[0004] This invention aims to solve the problem that current windproof and heat-insulating curtains affect workers' access routes, thereby impacting construction progress.

[0005] This utility model provides a windproof and heat-insulating curtain for concrete curing, including a winch, a safety clamp, a curtain body, and a roller. The roller is set on the upper side of the concrete to be cured. The output shaft of the winch is connected to the roller by a transmission belt. The roller is fixedly equipped with a safety clamp, which is fixedly connected to the upper end of the curtain body. The width of the safety clamp and the curtain body is adapted to the width of the concrete to be cured.

[0006] As a preferred embodiment, the upper end of the curtain is wound around the outside of the roller and multiple bolts are used to fix the wound portion of the curtain.

[0007] As a preferred embodiment, the safety clamp includes a C-shaped sleeve and a clamp, wherein the C-shaped sleeve is fitted onto the outside of the roller, and the clamp is fixedly installed at the lower end of the C-shaped sleeve and clamps the upper end of the curtain.

[0008] As a preferred embodiment, the curtain comprises, from the outside to the inside, a protective layer, an insulation layer, and a contact layer.

[0009] As a preferred embodiment, the protective layer is a high-density polyethylene woven fabric or a PVC coated fabric.

[0010] As a preferred embodiment, the insulation layer is a closed-cell foam plastic or an aluminum foil reflective layer.
