AI Technical Summary
Modular buildings have insufficient fire resistance at the joints of wall panels. Existing technologies often use sealing materials that are prone to failure or have complex structures, which can lead to the easy spread of flames and low construction efficiency.
It adopts a combination structure of rigid surface layer, filling layer, end cap, protrusion, groove and fireproof strip. The filling layer uses flame retardant material, and the groove is equipped with fireproof strip to release flame retardant gas through micropores. The rigid surface layer is fireproof gypsum board, and the end cap is fixed to the surface layer with fireproof adhesive, which simplifies the splicing structure.
It achieves high fire resistance, reduces production and construction costs, simplifies the installation process, and meets the needs of rapid construction of modular buildings.

Abstract
Claims
1. A fire rated wall panel splice construction for modular buildings, characterized by, It includes two hard surface layers arranged opposite each other, with a filling layer between the hard surface layers; The filling layer has a left end cap at the left end and a right end cap at the right end. The left end cap has a protrusion on the left side and the right end cap has a groove on the right side that matches the protrusion. The groove has multiple strip-shaped notches inside, and a fireproof strip is installed in each strip-shaped notch. The fireproof strip is a hollow square plate, and the interior of the fireproof strip is filled with aluminum hydroxide or a mixture containing aluminum hydroxide. The fireproof strip has micropores, which are directly opposite the joint between the groove and the protrusion.
2. A fire resistant wall panel assembly for modular construction according to claim 1, wherein, The filling layer is made of one or a mixture of flame-retardant foam, rock wool, or expanded vermiculite.
3. A fire resistant wall panel assembly for modular construction according to claim 1, wherein, The left end cap is fixedly connected to the hard surface layer and the filling layer with fire-retardant adhesive; the right end cap is fixedly connected to the hard surface layer and the filling layer with fire-retardant adhesive.
4. A fire resistant wall panel assembly for modular construction according to claim 1, wherein, The rigid surface layer is made of one of the following materials: fireproof gypsum board, metal composite fireproof board, or fiber-reinforced cement board, and the thickness of the rigid surface layer is 5-15mm.
5. A fire resistant wall panel assembly for modular construction according to claim 1, wherein, The strip-shaped notches are evenly distributed along the length of the groove, and each individual gap has at least one strip-shaped notch.
6. A fire resistant wall panel assembly for modular construction according to claim 1, wherein, The end of the protrusion is provided with a guide arc, and the entrance of the groove is provided with an inlet arc that matches the guide arc.
