H-shaped steel beam side concrete formwork structure

Technical Field

The utility model relates to a H shaped steel roof beam side concrete form structure, but wide application in the position department that the concrete protection girder steel need be pour in the girder steel outside.

Background

In steel structure construction, the protection of steel members generally includes corrosion prevention, fire prevention, and exterior decoration of buildings. Wherein, the corrosion prevention is finished in the processing and manufacturing links by adopting a paint spraying mode; fire prevention adopts a mode of spraying fire-proof paint, and the method of building external decoration has various forms and is finished on a construction site. The steel beam at the outer wall needs sound insulation and waterproof protection in addition to corrosion protection, fireproof protection and decoration.

At present, a common protection method in a steel structure building is related to a building form, and after fireproof paint is sprayed on a public building, the public building is treated in a mode of an external curtain wall decoration panel. This approach works well overall, but takes up a large amount of building space.

In steel structure houses, particularly common-grade houses, the problems of the cladding of steel beams and the coating of an outer wall facade and materials which are not common are solved continuously. If the fire-proof coating is still used for coating, the durability, the caking property and the like of the coating material limit the selection of the existing materials, and bring difficulty to engineering application.

Casting concrete on the outside of the steel beam is a relatively reliable solution. The concrete-steel composite wall is characterized in that the concrete-steel composite wall is made into a cement-based integral wall body by combining the relative relation of the concrete of the outer wall, the floor slab and the steel beam, so that the steel beam can be effectively protected, and meanwhile, a foundation wall can be provided for a subsequent external heat insulation method.

Because the distance between the outer side line of the building outer wall and the flange side line of the steel beam is smaller and is not larger than 50m in general, the pouring construction convenience of the concrete on the beam side and the forming quality of the concrete have certain problems, and the implementation of projects is troublesome.

The utility model has the advantages that:

1. the structure is simple and complete. The mode that the funnel was set up at the interval is adopted, on traditional wooden template basis, does not increase other special material and technology, only sets up inclined template and two triangle templates, simple structure.

2. The construction is convenient and fast. Traditional carpenters can set up the inclined formwork according to the determining deviation when constructing roof beam side form board and roof beam die block board, construction convenience.

3. The beam side concrete has good forming quality. Due to the existence of the spacing funnel, the pouring of the concrete is easier, and the forming quality of the beam side concrete is easy to control.
