Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically to a prefabricated composite slab structure with good stability. Background Technology

[0002] Precast composite slabs, also known as composite floor slabs, are assembled monolithic floor slabs made by stacking precast slabs and cast-in-place reinforced concrete layers. The cast-in-place concrete layer is the main component of the composite floor slab, and its thickness varies depending on the span of the floor slab, but it should at least be equal to the thickness of the precast thin slab.

[0003] Research revealed that precast composite slabs suffer from insufficient support strength during use. For example, precast composite slabs are assembled monolithic floor slabs composed of precast slabs and cast-in-place reinforced concrete layers. The composite slabs rely solely on the precast slabs and cast-in-place steel reinforcement for support, resulting in poor overall support strength. Furthermore, the thickness of the steel reinforcement inside the precast slabs is relatively small, which affects the stability of the support.

[0004] There is an urgent need for a more stable prefabricated composite slab structure to address the technical deficiencies mentioned above. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a precast composite slab structure with good stability, comprising a precast slab body, wherein prestressed steel bars and transverse perforated steel bars are respectively installed inside the precast slab body, a reinforcing plate is installed at the top of the precast slab body, a thermal insulation layer is installed at the top of the reinforcing plate, a sound insulation layer is installed at the top of the thermal insulation layer, a composite slab body is installed at the top of the sound insulation layer, a steel truss is fixedly connected to the top of the composite slab body, cast-in-place steel bars are installed between the steel trusses, a fixing plate is fixedly connected to the bottom of the precast slab body, a connecting column is fixedly connected to the bottom of the fixing plate, an embedded part is fixedly connected to the bottom of the connecting column, and a reinforcing component is installed inside the reinforcing plate;

[0007] The reinforcing component includes rectangular ribs with pre-reserved grooves inside. Supporting steel bars are installed at the top of the precast slab body, and casting blocks are poured on the outside of the supporting steel bars. Folded steel bars are installed between the rectangular ribs.

[0008] Preferably, a support block is fixedly connected between the precast slab body and the insulation layer.

[0009] Preferably, nine sets of the casting blocks are provided, and the casting blocks are embedded inside the reserved grooves.

[0010] Preferably, the bottom end of the sound insulation layer is fixedly connected to a limiting block, and the interior of the thermal insulation layer is provided with a limiting groove.

[0011] Furthermore, the limiting slot is U-shaped, and the limiting block is embedded inside the limiting slot.

[0012] Preferably, the sound insulation layer is made of nano-aluminum-magnesium damping sound insulation felt.

[0013] Preferably, barbed rods are fixedly connected to both sides of the connecting column, and two sets of reserved holes are provided inside the embedded part.

[0014] Preferably, the embedded part is provided in three sets, and the bottom end of the embedded part is fixedly connected to three sets of reinforcing steel bars.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the prefabricated composite slab structure with good stability not only realizes the function of enhancing the support strength and the function of enhancing the pre-embedded firmness, but also realizes the function of sound insulation and heat preservation.

[0016] (1) By setting up a reinforcing plate, a rectangular rib, a zigzag steel bar, a support block, a support steel bar and a casting block, the reinforcing plate is installed between the precast slab body and the composite slab body. The reinforcing plate can enhance the overall firmness of the composite slab body. The rectangular rib inside the reinforcing plate and the support steel bar form a firm support. The casting block outside the support steel bar can enhance the strength of the support. This structure realizes the function of facilitating the enhancement of the support strength.

[0017] (2) By setting up embedded parts, reinforcing bars, reserved holes, barbs, fixing plates and connecting columns, the embedded parts can be used to install the main body of the composite slab. During installation, the embedded parts need to be installed in the designated area for pouring. The reinforcing bars at the bottom of the embedded parts can be inserted into the interior of the installation area, which increases the area of ​​the connection and thus improves the stability of the installation. The connecting columns above the embedded parts are equipped with barbs, which can strengthen the stability of the horizontal installation. This structure realizes the function of facilitating the enhancement of the stability of the embedded parts.

[0018] (3) By setting up insulation layer, sound insulation layer, limiting block and limiting slot, the insulation layer can be installed on the precast slab body to insulate it. When the precast slab body is installed and used in the building, the insulation layer can enhance the overall insulation effect.

This structure enhances the sound insulation and heat insulation function of the composite slab. Attached Figure Description
