Description

Support metal construction in dysmorphism canopy

Technical Field

The utility model belongs to the technical field of steel structure inner supporting metal curtain walls, and particularly relates to a special-shaped canopy inner supporting metal structure.

Background

The traditional steel structure inner support of the metal curtain wall is mainly of a large-plane modeling structure, and is provided with special metal components, special locking strip plates and other matched parts, so that the line is simple, the structure is simple, and the construction operation is convenient. Although part of the appearance structure is complex, the structure can be uniformly adjusted through a stress beam of a main steel structure and the like, and the structure is inspected point by point in the construction process and uniformly controlled. When the engineering quantity is small, the problems of obvious structure quality, construction difficulty and the like can not occur. However, when the amount of work is relatively large, many technical difficulties and quality problems in the construction process are often exposed. Such as:

1. when the installation process of the modules of different planes of the curtain wall is controlled by the steel structure stressed main beam, construction technicians usually need to control various indexes such as the elevation size, the horizontal size, the inclination angle and the like of each main beam one by one in the construction process of each main beam, the requirement on the comprehensive service capacity of the constructors is high, and the personnel selection cost is increased.

2. When the size of the curtain wall with a complex profile structure is uniformly adjusted and checked through the steel structure stress main beam, the installation, fixation, operation and construction are very difficult, the workload of workers is increased remarkably, the labor time is prolonged, the construction period is prolonged, and the construction cost is obviously improved.

3. If the steel structure engineering by atress girder control when the great problem of local dimensional deviation appears, the conventional processing is mostly the cutting and welds again, and this method not only can cause the material waste serious, influences the curtain pleasing to the eye moreover.

For example, in a certain construction project, the canopy of engineering design adopts the form of steel construction encorbelmenting and outsourcing curtain wall for the special-shaped metal curtain wall that many specifications rectangle plane are connected with different angles, and this canopy atress system mainly uses the square steel of encorbelmenting as the owner, and overall structure encorbelments overall length is 5 meters, and the width is about 12 meters. The specification of the overhanging girder section bar is J200 × 150 × 8 hot galvanizing rectangular square steel, and the length dimension is 3.47 meters; the end modeling and the secondary beam and the brace rod at the upper space modeling part use hot galvanizing rectangular square steel with the specification of F50 x 3 as a main stress system. Because the lower main overhanging square steel single piece has larger dead weight and the end part is fixed in a welding mode, the installation worker needs to cooperatively operate and construct by a plurality of people, the difficulty is higher and the operation is inconvenient; and the main cantilever beam is a direct acting point of the bottom metal plate curtain wall, and important data such as the whole bottom horizontal elevation, the structure inclination angle and the like are controlled, so that all size data need to be checked in the construction process, the technical investment is increased, and the error probability is higher.
