Description

Technical Field

[0001] This utility model belongs to the field of building floor slab technology, specifically an energy-saving and heat-insulating prefabricated building floor slab structure. Background Technology

[0002] Prefabricated buildings, with their advantages of fast construction speed, controllable quality, and factory production, are gradually becoming the mainstream in the construction industry. This has driven the widespread application of precast floor slabs and other structural modules to achieve factory-based, standardized, and industrialized construction. However, on-site splicing is often imprecise, easily leading to gaps, misalignments, and seams, affecting the integrity and durability of the floor slabs. With the global energy crisis and increasing environmental awareness, energy conservation and environmental protection have become important directions for the development of the construction industry. Building energy consumption accounts for a large proportion of energy consumption, prompting the construction industry to continuously explore efficient thermal insulation and energy-saving design solutions. Existing traditional structures are prone to thermal bridging, resulting in significant heat loss and affecting the overall energy efficiency of buildings.

[0003] Meanwhile, a cast-in-place sandwich insulated shear wall structure and prefabricated building with application number CN201721736405.7 includes a concrete wall and an insulation board. The insulation board is vertically embedded in the middle of the concrete wall. First steel meshes are vertically embedded on both sides of the insulation board in the concrete wall. Multiple supports are evenly distributed on the insulation board, and the two ends of the supports are connected to the first steel meshes on both sides. The insulation board has low requirements for waterproof, flame retardant and crack resistance performance. The insulation board is placed in the middle of the wall and is isolated from the outside. It has a long service life and requires no maintenance. It not only has the function of heat insulation, but also reduces the amount of concrete used in the wall, reduces the weight of the wall, and has good sound insulation effect.

[0004] However, the following problems were found in the implementation of the relevant technologies: they cannot achieve continuous heat preservation, which easily leads to thermal bridging, resulting in a large amount of heat loss and affecting the energy-saving effect of buildings, especially during winter heating and summer cooling.

[0005] Therefore, we propose an energy-saving and heat-insulating prefabricated building floor structure. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides an energy-saving and heat-insulating prefabricated building floor structure, which has the advantages of forming a continuous insulation layer, avoiding thermal bridges, effectively blocking heat conduction through the floor, walls or structural nodes, reducing energy consumption, and thus improving the building's energy efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving and heat-insulating prefabricated building floor slab structure, comprising a first spliced ​​floor slab, on which a second spliced ​​floor slab is installed, a first extended plate fixedly connected to the outer surface of the first spliced ​​floor slab, the first extended plate having positioning holes, a second extended plate fixedly connected to the outer surface of the second spliced ​​floor slab, a reinforcing positioning column fixedly connected to the lower surface of the second extended plate, the first and second spliced ​​floor slabs comprising an outer floor slab layer, an insulation cavity provided within the first and second spliced ​​floor slabs, a reinforced concrete layer provided between the insulation cavity and the outer floor slab layer, an upper insulation board fixedly connected to the upper surface of the first and second spliced ​​floor slabs, a lower insulation board fixedly connected to the lower surface of the first and second spliced ​​floor slabs, and a concrete pouring area provided between the first and second extended plates.

[0008] Preferably, the lower insulation board and the upper insulation board are made of extruded polystyrene board.

[0009] Preferably, the reinforcing positioning post is movably connected to the positioning hole, and the interior of the reinforcing positioning post is composed of several reinforcing steel bars arranged in a row.

[0010] Preferably, the second extended plate is movably connected to the first spliced ​​floor slab, and the first extended plate is movably connected to the second spliced ​​floor slab.

[0011] Preferably, a baffle is fixedly connected to the upper surface of the first extension plate, and the baffle is movably connected to the second extension plate.

[0012] Preferably, concrete is poured in the concrete pouring area, and the concrete is mixed with the reinforcing positioning column.

[0013] Preferably, the concrete is in close contact with the first extension plate and the second extension plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model forms a continuous insulation layer by combining a reinforced concrete layer, a lower insulation board, an upper insulation board, and an insulation cavity. This avoids thermal bridges, isolates the heat transfer path of thermal bridges, and the continuous high-efficiency insulation layer can effectively block heat conduction through the floor slab, walls, or structural nodes, reducing energy consumption during winter heating and summer cooling, thereby improving the energy efficiency of the building and ensuring the structural stability of the floor slab.

[0015] 2. This utility model uses a prefabricated splicing method to install floor slabs through the cooperation of a first splicing floor slab, a second splicing floor slab, two extended slabs, a concrete pouring area, positioning holes and reinforcing positioning columns. The floor slabs are prefabricated in the factory, and only assembly and a small amount of pouring are required on site, reducing the on-site pouring and curing process, significantly shortening the construction cycle, and using the positioning structure to ensure accurate splicing, improve the assembly speed, and shorten the overall construction period.
