Concrete composite heat-preserving building block
The invention discloses a concrete composite heat-preserving building block. The concrete composite heat-preserving building block consists of a building block and heat preserving blocks. The building block is provided with two longitudinal elongated grooves penetrating through the upper plane and the lower plane, each elongated groove is provided with the heat-preserving block in an insertion manner to form a heat-preserving insulation structure. Two sides of each elongated groove are respectively provided with vertical blind grooves which are arranged in parallel and start from the bottom surface, each row of blind grooves are arranged in a segmenting manner, and the blind grooves which are arranged in parallel at intervals in the building block form a sound-proof structure. Two end surfaces in the length direction of the building block are respectively provided with vertical open slots corresponding to the positions of the blind grooves, and the open slots which are arranged in a staggering manner on the same end surface form a double waterproof structure. The heat-preserving insulation structure is integrated with the sound-proof structure, and a waterproof structure on a joint seam is additionally arranged, so that the heat-preserving effect and the sound-proof effect are good, the weight is also greatly reduced, and the concrete composite heat-preserving building block is a novel wall material for substituting a solid clay brick at present. 1. A concrete composite heat-insulation building block, which is composed of a rectangular block (1) and the plate-shaped insulation block (2); ; characterized in that the building block (1) is provided with two longitudinal inebriant (1.3), two vertical and parallel inebriant of (1.3) through the block (1) upper and lower plane, each of the defect only (1.3) is inserted into the insulation block (2) to form an insulating structure; inebriant in (1.3) sets are respectively parallel to two sides of the vertical groove in the bottom surface (1.2), each row of trough (1.2) arranged; block (1) of the parallel, spaced blind in (1.2) sound insulation structure a; block (1) two end surfaces in the length direction of the corresponding trough (1.2) is provided with a vertical open slot position (1.1), and with one end face of the slot on the staggered arrangement (1.1) a double waterproof structure. 2. Concrete composite heat-insulation building block according to Claim 1, characterized in that the insulation block (2) is a 15 mm -25 mm thick EPS board. 3. Concrete composite heat-insulation building block according to Claim 1, characterized in that the stated inebriant (1.3) and the trough (1.2) in the conical cavity.
