Protective device for road-crossing cast-in-place box girder construction and construction method thereof
The invention discloses a protective device for road-crossing cast-in-place box girder construction and a construction method thereof.The protective device comprises plywood, a plurality of pull rods and a plurality of I-shaped steel, the I-shaped steel is fixedly arranged on the bottom face of the plywood, and each I-shaped steel is provided with a first wing plate, a web and a second wing plate; the first wing plate and the second wing plate are oppositely arranged and connected through the web, the plywood is supported through the first wing plate and the second wing plate, the pull rod penetrates through the web and the plywood, the pull rod and the web are fixed through the first end of the pull rod, and the second end of the pull rod is fixed to the end face, facing the road surface, of the road-crossing cast-in-place box girder construction support. The plywood can reduce the dead weight of the structure and is convenient to process; in addition, the plywood is supported through the first wing plates and the second wing plates of the I-shaped steel, and the web plates of the I-shaped steel and the plywood are fastened through the pull rods to form a protection system, so that site materials for road-crossing cast-in-place box girder construction can be fully utilized, and the construction preparation time is shortened.
本发明公开了一种用于跨路现浇箱梁施工的防护装置及其施工方法，防护装置包括胶合板、若干拉杆和若干工字钢，各工字钢均固设于胶合板的底面，各工字钢均具有第一翼板、腹板和第二翼板，第一翼板与第二翼板相对设置且通过腹板连接，胶合板通过第一翼板和第二翼板承托，拉杆穿设于腹板和胶合板，拉杆与腹板之间通过拉杆的第一端部固定，拉杆的第二端部固定于用于跨路现浇箱梁施工支架朝向路面的端面。本发明采用胶合板能减轻结构自重且加工方便；此外，通过各工字钢的第一翼板和第二翼板承托胶合板，以及通过各拉杆将各工字钢的腹板与胶合板紧固，以形成防护体系，使得本发明能够充分利用跨路现浇箱梁施工的现场材料，以减少施工准备时间。
