Description
Technical Field
The utility model belongs to the technical field of energy-saving building materials, and particularly relates to a self-heat-preservation concrete composite building block.
Background
The self-heat-insulating concrete composite building block is a building material integrating building enclosure structure and heat insulation, and has the advantages of light weight, high strength, heat insulation, sound absorption, sound resistance, simple construction, low cost and the like. The bridge-cut-off (sandwich structure) self-heat-insulation concrete block can greatly reduce the generation of a heat bridge, has a good heat-insulation effect and becomes the main stream of the market. At present, the self-heat-insulating concrete composite block generally adopts B-class materials such as EPS, XPS and the like as heat-insulating materials, but according to the specification of building design fireproof standard GB 50016-2014, when the B-class materials are adopted as heat-insulating layers, the building outer wall is provided with at least 50mm A-class material fireproof layers. In order to meet the standard requirements, the existing self-heat-preservation building blocks are generally provided with a concrete fireproof protection layer with the thickness of 30mm outside the class-B material.
In view of wall safety, the 30mm protective layer is mainly tied by a steel bar connecting piece or a connecting piece with a blocking heat bridge, and due to corrosion of steel bars and aging of plastic connecting pieces, the application life and durability of the protective layer are problematic, and the protective layer is used as a non-structural member with hidden quality hazards.
If the structure of the self-insulation concrete composite building block can be improved, the potential safety hazard caused by the outer protective layer is solved, and the self-insulation concrete composite building block can be better matched with other novel building materials for use, and has good development prospect.
Disclosure of Invention
In order to solve the defects in the prior art, the utility model provides a self-heat-preservation concrete composite building block.
The technical scheme of the utility model is realized as follows:
the self-heat-insulating concrete composite building block consists of a main building block, a class A fireproof heat-insulating layer and an anti-cracking protective layer. Wherein the A-level fireproof heat-insulating layer is positioned between the main building block and the anti-cracking protective layer.
Preferably, the main body block is any one of a hollow concrete block, a lightweight aggregate concrete block and a foam concrete block.
Preferably, the A-level fireproof heat-insulating layer (2) is any one of a cement-based pressed homogeneous plate, a thermosetting polystyrene foam heat-insulating plate and a foaming cement plate.
The block main body is connected with the A-level fireproof heat-insulating layer through a dovetail groove.
Further preferably, a connector is connected with the block body through the A-level fireproof heat-insulating layer.
As the A-level fireproof heat-insulating layer is adopted, the B-level heat-insulating material does not exist in the building block, and the problem that the B-level heat-insulating material is required to be provided with a 50mm protective layer according to building fireproof design specifications does not exist. The block main body and the A-level fireproof heat-insulating layer are connected by adopting a dovetail groove, so that the problem of falling possibly caused by bonding mortar is avoided. The drawknot piece further strengthens the connection firmness of the A-level fireproof heat-insulating layer and the building block main body. The anti-cracking mortar layer with the thickness of the anti-cracking protective layer being generally 3mm to 5mm plays a role in enhancing the impact resistance of the surface of the A-level fireproof heat-insulating layer.
Advantageous effects
The utility model omits the outer protective layer of the conventional sandwich structure self-heat-preservation concrete composite building block, and eliminates the potential safety hazard caused by the outer protective layer. Compared with the prior art, the novel plastic composite material has the advantages of simple structure, low material cost, and is all of class A materials. The structural form of the building block is similar to that of a heat-insulating dismantling-free template wall system, and the building block and the heat-insulating dismantling-free template wall system can be well matched.
