Floor expansion joint structure used in complex use environments and construction method thereof

Abstract

The invention relates to a floor expansion joint structure used in complex use environments. The floor expansion joint structure used in the complex use environments includes floors, an expansion joint, a floor edge sealing steel structure, an expansion joint waterproof structure and an expansion joint force transferring structure. The floor edge sealing steel structure includes closed angle steeland an edge sealing light-gauge steel section, the top of the edge sealing light-gauge steel section supports the bottom end of the closed angle steel, and the top of the edge sealing light-gauge steel section and the bottom end of the closed angle steel are fixedly connected; and the outer side face of the edge sealing light-gauge steel section is flush with the side end faces of the floors at the corresponding positions, and the bottom side face of the edge sealing light-gauge steel section is flush with the lower side faces of the floors. The expansion joint is filled with the expansion joint waterproof structure, and the expansion joint force transferring structure comprises a force transferring steel plate and a force transferring steel plate sleeve. According to the floor expansionjoint structure used in the complex use environments, the floor edge sealing steel structure is designed at the expansion joint of the floors and used as the formwork when concrete is poured on the floors, the convenience and quality of concrete pouring are ensured, and plate joints are prevented from being damaged due to collision; and according to the arrangement of the expansion joint waterproof structure and the expansion joint force transferring structure, the requirements of the deformation, load bearing and durability of the expansion joint in the complex use environments can be met.

Description

technical field [0001] The invention relates to the field of floor expansion joints in industrial building structure design, in particular to an expansion joint structure used in extreme environments and a construction method thereof. Background technique [0002] In the construction floor of industrial plants or laboratories, it is generally required to set up floor expansion joints to prevent concrete shrinkage and temperature changes from causing cracks. For indoor floors, only shrinkage joints are generally provided, including flat joints, tongue and groove joints and false joints. For outdoor floors, expansion joints are required to adapt to deformation caused by temperature changes. For indoor special test plants in complex and extreme environments, the floor is the carrier of various experiments. It is directly exposed to experimental environments including high and low temperature, rain and snow. The drastic changes in cold and hot temperatures will cause deformation...
