Steel roof capable of preserving heat, resisting water and bearing person

Abstract

The invention provides a steel roof capable of preserving heat, resisting water and bearing persons, and relates to a novel building structure, belonging to the technical field of construction. An I-shaped secondary beam is fixed on a girder; a steel structure net rack is arranged at the lower part of the girder; a full welded steel roof boarding is arranged on the secondary beam; the surface of the steel roof boarding is provided with a cement ceramsite slope marking layer, a cement mortar screeding layer, a main waterproof layer, a polystyrene foam insulating layer, an outer waterproof layer, a fine stone cement layer, an adhesive layer and a decorating ground tile layer in sequence. The steel roof is characterized in that a folded expansion joint section is arranged on the steel roof. The steel roof provided by the invention can bear the roof dead load and the roof live load, and transmits the roof dead load and the roof live load to a wall column main body; because the steel roof boarding is provided with the folded expansion joint section, the steel plate can be manufactured in factories, are convenient for construction, and causes the steel roof boarding to have an expansion function of automatic absorption of expansion and contraction deformation; in addition, the expansion joint is not required to process additionally, an exhaust system and air bleeders on the roof are not required to install; and the roof can be further developed and utilized.

Description

technical field [0001] The invention relates to a novel building structure and belongs to the technical field of construction. Background technique [0002] In the engineering structure, the existing building roofs are divided into: reinforced concrete roof, steel structure roof and grid roof.

Reinforced concrete roof consists of steel bars and concrete to form a horizontal structural system. Disadvantages: 1. It does not conform to the development direction of energy conservation and environmental protection; 2. It increases the weight of the structure; the steel structure roof is made of steel structure and glass, pressed thin steel plate or other plates Constituting a horizontal structural system, the disadvantages: 1. Can’t get on people; 2. Poor thermal insulation; grid roof is a horizontal structural system composed of steel grid and ALC board, glass, pressed thin steel plate or other plates, insufficient Disadvantages: 1. Can't get on people; 2. Poor thermal insulation

The structure is composed of grid frame, steel bracket, section steel and 4mm thick steel plate. Since the steel plate is made of thick steel plate, no other support structure is needed, and it can bear the horizontal load of the roof itself. The area covering the entire roof is formed in this way. Although its waterproof effect is good, it does not have the expansion and contraction function of automatically absorbing thermal expansion and contraction. It can only be processed by making expansion joints on the upper surface.
