With the continuous improvement of people's living standards, environmental protection and energy saving have increasingly become the consensus of everyone. At present, the technology of using fly ash, waste slag and other industrial wastes to prepare hollow blocks has been relatively mature. In order to save energy while utilizing waste, and improve the thermal insulation, heat insulation, and sound insulation functions of buildings, people have adopted many technical measures for hollow blocks to improve the thermal insulation, heat insulation, and sound insulation functions of blocks. However, in these technical measures, either the thermal insulation and sound insulation effects of the blocks are improved, but the structure is more complicated and the production cost is high; Relatively poor.

Utility model content

The purpose of the utility model is to overcome the disadvantages of the prior art and provide a concrete composite self-insulation block with simple structure, good thermal insulation, heat insulation and sound insulation effects, good load-bearing performance and low production cost.

The purpose of this utility model is achieved through the following technical solutions: concrete composite self-insulating block, which includes a light aggregate concrete block body, and the upper surface of the light aggregate concrete block body is provided with three rows extending along the vertical direction. Through holes, among the three rows of through holes, the middle through hole row in the middle part is evenly distributed with two parallel through holes, and the edge through hole rows located on both sides of the middle through hole row are each provided with a through hole, The left side wall of the light aggregate concrete block body is provided with two vertically extending through grooves, and the right side wall of the light aggregate concrete block body is also provided with two grooves symmetrically arranged on the left side wall. The through groove, the through hole and the through groove are filled with foamed concrete.

The two through grooves set on the left side wall are respectively located in the same plane as the through holes of the two edge through hole rows, and the width of the through grooves is the same as the width of the through holes; the two grooves set on the right side wall The through grooves are respectively located in the same plane as the through holes of the two edge through hole rows, and the width of the through grooves is the same as that of the through holes.

The distance between the through hole and the adjacent through hole, the through groove or the outer surface of the light aggregate concrete block body and the distance between the through groove and the outer surface of the adjacent light aggregate concrete block body are equal.

The utility model has the following advantages: the utility model adopts a relatively simple structure, which not only makes the supporting blocks have better thermal insulation, heat insulation and sound insulation effects, but also has better load-bearing performance, and the production cost is lower. The wall body built by adopting the utility model does not need to add heat preservation, heat insulation and sound insulation measures, which not only saves energy but also reduces costs for users. The technical effect produced by the utility model is remarkable. After inspection, all the technical indicators of the utility model meet the national standards for building blocks, and the product quality meets the indicators of "Small Hollow Blocks for Light Aggregate Concrete" (GB/T15229-2011) And "Adiabatic Steady State Heat Transfer Properties Determination Calibration and Protected Hot Box Method" (GB/T13475-2008).

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described, and the protection scope of the utility model is not limited to the following:

As shown in Figure 1, the concrete composite self-insulating block includes a light aggregate concrete block body 1, and the upper surface of the light aggregate concrete block body 1 is provided with three rows of through holes 2 extending vertically, Among the three rows of through holes 2, the middle through hole row 3 in the middle is evenly distributed with two parallel through holes 2, and the edge through hole rows 4 on both sides of the middle through hole row 3 are each provided with a through hole. Hole 2, the left side wall 5 of the light aggregate concrete block body 1 is provided with two vertically extending through grooves 6, and the right side wall 7 of the light aggregate concrete block body 1 is also provided with two The through grooves 6 on the side wall 5 are symmetrically arranged, and the through holes 2 and the through grooves 6 are filled with foamed concrete 8 . The right side wall 7 and the left side wall 5 are symmetrically provided with through grooves 6, which is convenient for two adjacent concrete composite self-insulating blocks to form a complete pouring hole when choosing any side, thus simplifying the concrete composite during masonry. The splicing operation of self-insulating blocks and the pouring holes formed by splicing the through grooves 6 also block the thermal bridge between the inner and outer layers of the wall, greatly improving the heat insulation effect of the wall.

The two through-slots 6 provided on the left side wall 5 are respectively located in the same plane as the through-holes 2 of the two edge through-hole rows 4, and the length from front to back is the width of the through-hole 2 or the through-slot 6 , and the width of the through groove 6 is the same as the width of the through hole 2; the two through grooves 6 provided on the right side wall 7 are respectively located in the same plane as the through holes 2 of the two edge through hole rows 4, and the through groove 6 has the same width as the through hole 2. This structure reduces the complexity of the mold structure for processing blocks and facilitates the processing of the molds; meanwhile, it also increases the pouring volume of the foamed concrete 8 to the greatest extent. In this embodiment, the length and width of the concrete composite self-insulating blocks are equal Both are 240mm, and the height is 190mm. The through hole 2 of the middle through hole row 3 is 90mm long and 60mm wide. The through hole 2 of the edge through hole row 4 is 90mm long and 50mm wide. The width of the through groove 6 is 50mm. Groove depth 45mm,

The distance between the through hole 2 and the adjacent through hole 2, the through groove 6 or the outer surface of the light aggregate concrete block body 1, and the distance between the through groove 6 and the outer surface of the adjacent light aggregate concrete block body 1 In this embodiment, the interval size is 20 mm. This structure improves the symmetry and uniformity of the overall block structure, and improves the stability and load-bearing performance of the masonry wall structure. the
