Description

Technical Field

[0001] The utility model relates to the technical field of building floor slab production, in particular to a building floor slab prepared by using foam concrete. Background Art

[0002] Precast concrete panels that can be used for building floors, referred to as precast panels, were a common form of floor panels in early 20th century buildings and are also a common precast component in modern buildings. Precast concrete panels refer to concrete panels that are prefabricated and reinforced in a prefabrication yard or production plant, and then transported to the construction site for installation. They are produced in a factory manner, through mold forming, processing reinforcement and sufficient maintenance. They are made with the characteristics of high strength, stable quality, light weight and easy construction.

[0003] The precast concrete panels used in existing building floors are mixed with special foam boards and foam concrete. While reducing the weight of the floor, the closed-cell structure can reduce heat loss, maintain a relatively stable temperature inside the building, and reduce noise propagation to a certain extent. However, in the existing production process of precast concrete panels, due to the light weight of the foam boards themselves, the position of the foam boards is easily shifted during the pouring of concrete, destroying the overall production structure. If the foam boards are shifted or damaged, the insulation layer will be broken or have gaps, thereby reducing the insulation effect. At the same time, it will also destroy the continuity of the sound insulation layer, resulting in a decrease in the sound insulation effect. Utility Model Content
