Description

Technical Field

[0001] The invention relates to the technical field of threshold structures, and in particular to a steel hoistway clean freight elevator threshold structure and a construction method thereof. Background Art

[0002] The steel beam at the threshold of the traditional steel structure elevator shaft is often flush with the side beam of the concrete structure. Due to the construction position deviation of the concrete beam and steel structure and the installation process requirements of the elevator threshold, there will be a gap of less than 50mm between the steel beam at the threshold and the elevator threshold and the structural beam. In order to meet the freight and clean and beautiful requirements of the clean freight elevator threshold, the gaps around the steel beams need to be repaired to ensure their force and appearance. For the gaps around the steel beams, one of the traditional treatment methods is to lay steel plates on the gaps and steel beams. However, too thick steel plates will cause the ground where the steel plates are laid to bulge and meet the clean ground flatness requirements (2mm / 2m), and too thin steel plates cannot withstand freight loads.

[0003] Another way to deal with it is to lower the steel beam and lay a steel plate or pour a concrete sill on the steel beam and the gap. If a steel plate is laid above the gap, the steel plate and the concrete beam may not be completely connected and flush. If a concrete sill is poured, the steel shaft and the concrete structure are hinged, while the steel beam and the concrete structure at the concrete sill are rigidly connected, which can easily lead to cracks in the sill. In addition, this method has the problem of difficulty in supporting the formwork at the sill, and the exposed concrete surface in the clean area (the bottom and sides of the sill) needs to be painted with epoxy paint, which makes the construction extremely inconvenient. Therefore, it is particularly important to set up a clean freight elevator sill structure that can ensure force, beauty and cleanliness requirements. Summary of the invention
