Embodiment 1

[0035] Example 1: The steel skeleton light-duty composite panel used as a roof panel, the steel skeleton adopts the form of a truss, which can reduce cold bridges and reduce steel consumption, because the roof panel belongs to the horizontal direction of the board, and can withstand wind, snow, and other related roofs For the load on the upper surface, it is more advantageous to adopt a micro-arch structure. On the one hand, it can reduce the deflection of the plate under load, and on the other hand, it is beneficial to control the deflection of the rigid surface layer on the lower surface due to the compression of the roof plate under the load state of the plate. resulting in tension cracking.

[0036] The reason why the steel skeleton light-duty composite panel includes the truss skeleton system, the arrangement of the diagonal stays should adopt The method is because this method will form a 2-3% upward deflection during the welding and forming process, so that the overall ...

Embodiment 2

[0046] Example 2: The steel skeleton light-duty composite panel used as the wall panel, the steel skeleton adopts the form of truss, which can reduce the cold bridge and reduce the amount of steel used, because the roof panel is used in the vertical direction and mainly bears the wind and wind suction load. The load level is smaller than that of the roof panel, and considering the aesthetics of installation and use, the layout of the truss cables should adopt Way. This method does not cause deflection deformation during the welding forming process, and the plate is flat and beautiful. Then use the flat main truss to assemble into a steel skeleton grid. The grid size is generally 750-900mm×1200-1500mm, and the area of ​​each grid does not exceed 1.2㎡. And the vertical support spacing of each truss is in the range of 400-1200mm, and it must be ensured that the angle between the diagonal stays of the steel frame light composite panel and the vertical support of the truss shall ...

experiment example 1

[0058] Theoretical calculations show that the theoretical steel consumption of the steel frame light plate steel frame structure that meets the design requirements is 19.64kg / ㎡, which is a conclusion obtained by checking and calculating each tie bar of the truss, but the actual steel frame light plate has formed a three-dimensional space As for the overall force, it is determined through actual inspection that the steel frame with light plate and steel frame meets the same check load, the actual steel consumption is 10.23kg / ㎡, and the difference in steel consumption represents the mutual arrangement of the internal structure of the steel skeleton. Finally, the technical optimization effect brought by the three-dimensional space is formed.

[0059] Theoretical calculations show that the theoretical steel volume of the three-dimensional space modeling of the light-weight plate-steel frame structure with a steel frame that meets the design requirements is 12.93kg / ㎡. Through actual...

Abstract

The invention relates to a steel frame light composite board which comprises a truss frame system. When the steel frame light composite board is applied in the horizontal direction or in the vertical direction, the arrangement of diagonal draw steel bars can be found in specifications. According to the scheme, compared with the scheme adopting cement foamed light boards, the integral combining strength between internal filling cement foamed materials which serve as thermal insulation materials and a steel frame is not taken into consideration, only the stereo spatial strength of a steel structure formed by combined truss grids or combined structural steel grids is calculated and checked, the integral board strength is not controlled by the strength of foamed cement, and the board strength can be calculated and checked according to design and application requirements. The area of the structural steel section is increased, adjustment and control are conducted by increasing the steel amount per square meter, and various mechanical indexes of the board are met.

Description

technical field [0001] The invention belongs to the field of construction and relates to a steel frame light composite board. Background technique [0002] The light insulation boards widely used today are mainly colored steel sandwich panels and cement foam light boards. Colored steel sandwich panels have low strength, poor thermal insulation and steam insulation performance, poor durability, and no fire resistance. Cement foam light-duty panels use the strength of cement foam to completely bond with the internal steel skeleton to form an overall strength. The overall panel strength is controlled by the strength of foam cement. This type of panel is due to linear expansion of steel and cement materials. The different coefficients will lead to cracks between the steel frame and the foam core material under the alternating action of cold and heat, which will affect the strength of the overall board, and the foamed cement is also used as an insulation material in the board, b...
