High-temperature large-temperature-difference steel structure roof truss and construction method of pottery clay plate in lower inclined surface of roof truss

Abstract

The invention discloses a high-temperature large-temperature-difference steel structure roof truss and a construction method of a pottery clay plate in the lower inclined surface of the roof truss. The steel structure roof truss comprises I-steel of the steel structure roof truss, T-shaped aluminum keel, the pottery clay plate, hooks, an aluminum corner connector, a main galvanized steel square keel and a galvanized steel corner connector, a first bolt and a pad are arranged between the aluminum corner connector and the T-shaped aluminum keel, the aluminum corner connector is provided with a long round hole, and the first bolt penetrates the long round hole and the pad is additionally arranged so that the aluminum corner connector is fixed to the T-shaped aluminum keel. According to the high-temperature large-temperature-difference steel structure roof truss and the construction method of the pottery clay plate in the lower inclined surface of the roof truss, a connection method is changed, the long round hole is used, the first bolt and pad are used for connection, an expansion-contraction stress can be released under a large-temperature-difference heat motion, routine construction can be carried out normally under the high temperature condition, the safety risk is low, the technical difficulty is low, operation is simple, work time is saved, the cost is reduced, and the quality is ensured.

Description

technical field [0001] The invention relates to the technical field of civil structure construction, in particular to a high-temperature and large-temperature-difference steel structure roof truss and a construction method for its lower-slope clay plate. Background technique [0002] With the use of space by human beings, the development of construction technology and the transformation of design concepts, what people pursue is the perfection of the structure and the symbol of the architectural shape, the design of the integrity and aesthetics of the building appearance, and the building facade of a university project in Kuwait. The elevations toward the two ends (elevation difference 870mm) are inconsistent and the sloped clay panels under the steel structure roof truss are constructed. In addition, the temperature in this area is as high as 67°C, the surface temperature of the material is as high as 100°C, and the temperature difference (up to ±50°C). It is very difficult ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a high-temperature and large-temperature-difference steel structure roof truss and its lower slope clay slab construction method, which has the advantages of simple and safe operation, saving man-hours, reducing costs, and ensuring construction quality. Conventional construction cannot meet the problem of constructing the sloped clay slab under the steel structure roof truss under the condition of high temperature and large temperature difference
