Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated building components, and more specifically to the technical field of a prefabricated grid roof panel and a grid assembly. Background Art

[0002] The existing grid structure roof panels are generally light sandwich panel roof panels or cast-in-place concrete roof panels; the light sandwich panel roof panels have poor durability and sound insulation effect and cannot bear weight; while the cast-in-place concrete roof panels are complex to construct, heavy and have a long construction period. The existing patents disclose the following technologies:

[0003] The patent with publication number CN205935350U and patent name "A prefabricated roof panel with steel trusses" discloses the following contents: a prefabricated roof panel with steel trusses; comprising a template and a plurality of steel trusses arranged side by side and installed on the template; nuts are arranged along the axial direction at the bottom of the steel trusses; mounting holes are arranged on the template, and the mounting holes are arranged corresponding to the nuts; the template is connected to the mounting holes corresponding to the nuts by bolts, and is fixed to the steel trusses by the nuts; by connecting the template to the bottom of the prefabricated steel trusses in a detachable manner, most of the floor slab steel bar binding operations are reduced, and the template has the advantage of being resistant to pressure, eliminating the template support operation, eliminating the risk of template collapse, speeding up the construction, and significantly reducing labor costs. After the construction of the floor deck is completed, the template can be removed and reused, saving construction costs.

[0004] The patent with publication number CN207194323U and patent name "A reinforced cement composite prefabricated thermal insulation roof panel with a steel wire grid" discloses the following content: A reinforced cement composite prefabricated thermal insulation roof panel with a steel wire grid, which is compositely formed by an upper fiber cement layer, a lower fiber cement layer, a middle thermal insulation layer composed of extruded polystyrene foam or rock wool for insulation, and a steel frame around it. A steel wire grid and angle steel stiffening ribs are also provided inside the roof panel; wherein the fiber cement layer panels are composed of alkali-resistant glass fiber mesh cloths on the upper and lower sides and a composite single board made of a mixture of low-alkali silicate cement, fly ash and ceramsite lightweight aggregate in the middle; the angle steel stiffening ribs are evenly spaced in one direction or two directions in the thermal insulation layer, and the four sides of the steel grid and the ends of the angle steel stiffening ribs are respectively welded to the inner side of the steel frame; the steel frame is a cold-bent thin-walled steel structure.

Since there will be a large three-dimensional spatial error between the actual spatial position of the node ball of the spatial grid structure and the positioning on the construction drawing, and the prefabricated roof panels are flat plates prefabricated according to the construction drawings, it is difficult to adjust the horizontal and vertical three-dimensional spatial errors of the prefabricated roof panels disclosed in the above patent during installation, so the prefabricated roof panels cannot be installed smoothly.
