An assembled rectangular flat roof and its manufacturing method

Abstract

The invention discloses an assembly type rectangular plane roof and a manufacturing method of the assembly type rectangular plane roof. Profile steel is adopted in a factory to be manufactured to be shearing keys and open-frame beams in advance, the shearing keys and the open-frame beams are manufactured to be assembly units A, assembly units B and assembly units C in a welding mode, wherein each assembly unit C is of a cross-shaped structure, each assembly unit B is of a #-shaped structure with a square grid, each assembly unit A is of an intersection structure with two square grids and with two transverse grid lines intersected with three longitudinal grid lines, then according to the regulated size of the narrow and long rectangular plane roof needing to be manufactured, the assembly units A and / or the assembly units B and / or the assembly units C are assembled on the scene to be combined into a spatial prismatic open-frame steel grid structure with integral assembling, and after a waterproof roof is paved on the spatial prismatic open-frame steel grid structure with integral assembling or lighting glass is installed on the spatial prismatic open-frame steel grid structure with integral assembling, the assembly type rectangular plane roof can be manufactured. The assembly type rectangular plane roof has the advantages of being simple in structure, low in manufacturing cost, small in steel using amount, high in structural strength, beautiful in shape and the like.

Description

technical field [0001] The invention relates to an assembled rectangular flat roof and a manufacturing method thereof, and belongs to the technical field of manufacturing narrow and long rectangular flat roofs or ceilings. Background technique [0002] With the rapid development of economic construction, the national road construction and hotel construction projects are increasing day by day. There are more and more projects using steel structures for the rectangular flat roofs of expressway toll stations all over the country and the ceilings at the entrances of large hotels. Due to functional requirements, the plane forms are all narrow and long rectangular planes, that is, the ratio of the front width to the depth is often greater than 2. For a long time, steel frame structures and square pyramidal steel grid structure systems have been used, and these structural systems have not been developed and improved. At the same time, it also leads to the same architectural shape. ...

AI Technical Summary

Problems solved by technology

In addition, since the existing rectangular planar roof is a narrow and long rectangular plan, the use of the above structure not only does not fully utilize the spatial three-dimensional mechanical effect of the roof (or ceiling), but also has the disadvantages of complex structure, difficult construction, and large amount of steel. problems, and the existing steel structures of these rectangular flat roofs are generally manufactured by on-site welding, which not only increases the workload of on-site construction, but also requires a long construction period. quality is not guaranteed

In addition, after the steel structure of the existing rectangular flat roof structure is fabricated, in addition to the waterproof roof, a suspended ceiling must also be fabricated, which not only increases the cost, but also has an unsatisfactory use effect

Therefore, the existing rectangular planar roof structure still cannot meet the needs of use
