Description

Technical Field

[0001] The present invention relates to the technical field of building blocks, and more specifically, to a hollow heat-insulating block wall and a construction method thereof. Background Art

[0002] In recent years, the rapid growth of building energy consumption in China has increasingly imposed pressure on energy and the environment. According to statistics, building energy consumption in China accounts for one-third of the total national energy consumption, and the heating and cooling energy consumption of buildings accounts for about 60% of the building energy consumption. Therefore, improving the heat insulation effect of the wall structure is the key to building energy conservation. The hollow heat-insulating block is the most widely popularized heat-insulating material in China at present, with the lowest construction and cost. The hollow heat-insulating block can be widely prepared from various solid wastes such as construction waste, desulfurized gypsum from power plants, fly ash, quartz tailings and tailings slag, and its manufacturing process is more low-carbon and environmentally friendly compared with organic heat-insulating materials. Therefore, improving the heat insulation effect of the hollow heat-insulating block and further promoting its application are of great significance for China's energy conservation and emission reduction work.

[0003] Improving the heat insulation effect of the wall structure is mainly promoted from two aspects: materials and structure. In terms of materials, using aerated concrete in the prior art to manufacture hollow blocks can achieve good heat insulation and fire prevention effects. In terms of structure, due to the lack of effective development for wall node parts such as structural beams, structural columns, secondary structural beams, and construction columns, the application of hollow heat-insulating blocks in the prior art is mostly limited to the mixed use of blocks and secondary structures, resulting in a decrease in the overall heat insulation of the wall and obvious local heat bridges. At present, there are few reported cases of applying hollow heat-insulating blocks to the above-mentioned wall node parts. Due to the existence of steel bars and concrete heat bridges arranged between layers at these node parts, their heat transfer coefficients are significantly greater than those of the main body of the exterior wall, becoming a weak link in the heat insulation of building walls. Although there are construction methods in the prior art to improve the heat insulation performance by pasting heat-insulating materials such as rock wool and polystyrene boards on structural beams and structural columns, due to the different materials (different thermal expansion coefficients) of these heat-insulating materials and the block materials used as the main body of the exterior wall, combined with factors such as the quality instability caused by cross-operation of the construction team (especially joint treatment), there is a risk that the heat insulation layers at the structural beam and structural column parts are prone to hollowing, cracking, water seepage and finally falling off.

[0004] Therefore, how to study a hollow heat-insulating block wall that can cover node parts such as structural beams, structural columns, secondary structural beams, and construction columns and thus improve the overall heat insulation effect of the exterior wall has become a technical problem that needs to be solved urgently by those skilled in the art. In view of this, the present invention is specifically proposed. Summary of the Invention

The U-shaped groove openings of the two third auxiliary blocks (41) at the left rear side and the right side and the inner wall of the third variant three auxiliary block (44) at the left front side are connected to form an "L" cavity. The "mouth" cavity of the odd courses of the corner wall construction column and the "L" cavity of the even courses of the corner wall construction column are connected to form the vertically penetrating pore passage. In the T-shaped wall construction column: The odd courses of the T-shaped wall construction column include one of the third auxiliary blocks (41). The left end face, the right end face, and the front end face of the third auxiliary block (41) are respectively connected to three of the main blocks (11). The U-shaped groove opening of the third auxiliary block (41) faces left or right, and the U-shaped groove opening of the third auxiliary block (41) and the main block (11) adjacent to it horizontally form a "mouth" cavity. The even courses of the T-shaped wall construction column include one of the first variant third auxiliary blocks (42) located at the left rear side, one of the second variant third auxiliary blocks (43) located at the right rear side, and one of the third auxiliary blocks (41) located at the front side. The left end face of the first variant third auxiliary block (42) at the left rear side, the right end face of the second variant third auxiliary block (43) at the right rear side, and the front end face of the third auxiliary block (41) at the front side are respectively connected to three of the main blocks (11). The U-shaped groove openings of the first variant third auxiliary block (42) at the left rear side, the second variant third auxiliary block (43) at the right rear side, and the third auxiliary block (41) at the front side are connected to form a "T" cavity. The "mouth" cavity of the odd courses of the T-shaped wall construction column and the "T" cavity of the even courses of the T-shaped wall construction column are connected to form the vertically penetrating pore passage. In the cross-wall structural column: the odd courses of the cross-wall structural column include an auxiliary block three (41) located on the front side and an auxiliary block three (41) located on the rear side. The front end face of the auxiliary block three (41) on the front side and the rear end face of the auxiliary block three (41) on the rear side are respectively connected to the two main blocks (11). The U-shaped groove openings of the two auxiliary blocks three (41) on the front side and the rear side communicate to form an "I"-shaped cavity; the even courses of the cross-wall structural column include an auxiliary block three (41) located on the left side and an auxiliary block three (41) located on the right side. The left end face of the auxiliary block three (41) on the left side and the right end face of the auxiliary block three (41) on the right side are respectively connected to the two main blocks (11). The U-shaped groove openings of the two auxiliary blocks three (41) on the left side and the right side communicate to form a "one"-shaped cavity; the "I"-shaped cavity of the odd courses of the cross-wall structural column and the "one"-shaped cavity of the even courses of the cross-wall structural column communicate to form the vertical through-hole passage.
