Description

Technical Field

[0001] This utility model belongs to the field of prefabricated buildings, and in particular relates to an integrated prefabricated composite slab and composite slab system that integrates sound insulation and heat preservation. Background Technology

[0002] In residential construction, there are specific requirements for the sound insulation and thermal insulation performance of floor slabs. To achieve this goal, the following three methods are commonly used:

[0003] Firstly, after the concrete floor slab is poured, an insulation material such as extruded polystyrene board is added to the building surface layer. On top of this insulation material, a layer of fine aggregate concrete is laid as a protective layer. However, cracking of the fine aggregate concrete layer is a common quality problem. Because the insulation and soundproofing materials are inherently weak layers, they have different material properties compared to concrete. These differences include differences in compressive strength and vertical deformation between the insulation and soundproofing materials and concrete, the adhesion between the insulation and soundproofing materials and the fine aggregate concrete, and insufficient aging time and inconsistent shrinkage of the insulation and soundproofing materials. These factors make both the insulation and soundproofing layers and the fine aggregate concrete layer prone to quality problems.

[0004] II. Precast composite slabs are commonly used precast components in the construction field. They are mainly composed of solid concrete slabs of a certain thickness and steel trusses on top. During construction, the composite slabs are installed, the upper layer of steel bars is laid on site, and concrete is poured to form a complete concrete floor slab. Casting floor slabs using composite slabs is a mature and widespread technology. However, it only serves a load-bearing function and contributes very little to sound insulation and heat preservation. It needs to be combined with the additional laying of sound insulation and heat preservation materials as described in the first technology to achieve the desired sound insulation and heat preservation effect for the building floors.

[0005] III. Precast composite hollow core slabs are a special type of floor slab. When the overall thickness of the floor slab is relatively thick, generally greater than 180mm, weight-reducing blocks can be laid on the top of the composite slab, with upper-layer steel reinforcement laid on top of the weight-reducing blocks, and then a layer of cast-in-place concrete is poured to form a relatively thick concrete floor slab. The weight-reducing blocks mainly serve to reduce weight. While the weight-reducing blocks objectively provide some sound insulation and thermal insulation, the solid concrete ribs between the weight-reducing blocks and the numerous solid sections at the joints of the composite slabs can create sound and thermal bridges. Furthermore, in technique III, the weight-reducing blocks need to be laid on-site, and due to differences in material properties, the possibility of cracking, as seen in technique I, may exist. These reasons limit the application of technique III and make it unsuitable for residential use.

[0006] Therefore, this utility model came into being.

[0007] It should be noted that the information disclosed in the background section of this utility model is intended only to enhance the understanding of the general background of this utility model, and should not be regarded as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0008] One objective of this utility model is to propose an integrated prefabricated composite panel that combines sound insulation and heat preservation.

[0009] The second objective of this utility model is to propose an integrated prefabricated composite panel system that combines sound insulation and thermal insulation.

[0010] To achieve one of the above objectives, this utility model first provides an integrated prefabricated composite panel that combines sound insulation and thermal insulation, comprising:

[0011] The prefabricated part includes a prefabricated base plate and connectors, wherein the connectors are disposed on the prefabricated base plate;

[0012] A thermal insulation and sound insulation layer, which is continuously formed on the precast base plate;

[0013] A laminated layer, wherein the laminated layer is formed on the thermal insulation and sound insulation layer;

[0014] The connector extends through the thermal insulation and soundproofing layer. The bottom of the connector is connected to the precast base plate, and the top extends into the composite layer. A first protective layer is formed between the top of the connector and the top surface of the composite layer, and a second protective layer is formed between the bottom of the connector and the bottom surface of the precast base plate.

[0015] Preferably, the side of the precast base plate extends outside the thermal insulation and sound insulation layer, forming an overlap groove with the thermal insulation and sound insulation layer; the overlap grooves of adjacent composite plates are joined together to form an overlap groove, and an overlap rib is provided in the overlap groove.

[0016] Preferably, the precast base plate has structural ribs that extend outward into the lap joint to form a bolted joint.

[0017] Preferably, the bolted portion overlaps with the lapped bar at least partially to form an effective lap.

[0018] Preferably, the lapped bar is a ring bar, and the top of the ring bar is located in the overlapping layer.

[0019] Preferably, the sides of the precast base plate are chamfered, and the chamfers between the precast base plates of adjacent composite slabs form a joint, with the joint facing downwards from the precast base plate.

[0020] Preferably, the connector is a connecting steel bar, a truss, or a composite rib; the composite rib includes a truss and a concrete rib, the concrete rib being formed at the top of the truss and embedded in the composite layer.

[0021] Preferably, the steel reinforcement of the truss is coated with a heat-insulating coating.

[0022] To achieve the above two objectives, this utility model also provides an integrated prefabricated composite slab system that combines sound insulation and thermal insulation, comprising at least two prefabricated composite slabs laid side by side, characterized in that adjacent prefabricated base slabs are laid side by side, and thermal insulation concrete is poured into the overlapping groove.

[0023] Preferably, there are multiple overlapping grooves, spaced along the side edge of the precast base plate.

[0024] Preferably, at least one of the composite slabs has a bottom slab structural reinforcement extending into the main building structure to form a support node.

[0025] The technical effects achieved by the above-mentioned technical solution of this utility model are derived from one or more of the following combinations:

[0026] By placing the thermal insulation layer in the middle of the composite slab, a sandwich structure is formed, creating a complete and continuous thermal and sound insulation layer inside the composite slab. This can effectively prevent cracking of the floor surface caused by laying the thermal insulation layer on site.

[0027] By merging the structural floor slab with the thermal insulation and sound insulation layer and the fine stone protective layer in the building surface layer, and replacing the original fine stone protective layer in the surface layer with the composite layer cast on site, the total floor thickness can be reduced, material costs can be saved, on-site procedures can be reduced, and material consumption can be reduced.

[0028] The prefabricated thermal and sound insulation materials are integrated into the production of composite panels, which can avoid on-site operations, reduce on-site processes, and ensure higher quality.

[0029] The thermal insulation layer is continuously arranged in the connection area and support node area, which reduces the existence of thermal bridges and acoustic bridges.

[0030] The problem of coordinated stress between the upper and lower layers (precast base plate and composite layer) is solved by using connectors, and the thermal insulation layer is continuously formed at the connector and joint positions, reducing the existence of thermal bridges and sound bridges.

[0031] Overlap grooves are provided between adjacent slabs, and a stable connection is formed through the effective overlap of bolted parts and lap bars. Attached Figure Description
