The invention provides a hollow concrete board with a sound insulation effect and a construction method of the hollow concrete board with the sound insulation effect and relates to the technical field of concrete components. The hollow concrete board with the sound insulation effect aims to solve the problem that part of a template is sealed in the existing hollow concrete board air layer and cannot be taken out and the sound insulation and noise reduction performance of the hollow floor is lowered. The hollow concrete board with the sound insulation effect comprises two baseboards which are arranged in parallel and at an interval and at least two horizontal beams which are arranged between the baseboards at intervals, wherein the upper baseboard is composed of a preset part and a post-pouring part which are arranged at an interval, two ends of the preset part are connected between the two horizontal beams, the post-pouring part is connected between the adjacent preset parts, and the post-pouring part and the preset part and the horizontal beams are connected into a whole. The construction method of the hollow concrete board comprises the following steps of preparing the preset part, pouring the lower baseboard and the horizontal beams, dismantling the template, arranging the preset part between the adjacent horizontal beams and closing a hollow cavity, pouring concrete in a groove formed between the adjacent preset parts and the horizontal beams and obtaining the hollow concrete board after the post-pouring part and the preset part are connected into a whole.
