Problems solved by technology

[0002] Self-insulating blocks are widely used due to their advantages of fast masonry speed and fast production. The current self-insulating blocks achieve 65% energy-saving requirements by setting an insulation layer inside the block. However, due to the inner wall of the block There is still a thermal bridge between the inner part and the outer wall part, and the energy saving efficiency is still low

[0003] Chinese patent 201220399916.5 discloses a composite self-insulating block, the inner wall and the outer wall are respectively connected to the insulation layer through dovetail grooves, and at the same time, there is a built-in tie piece passing through the insulation layer between the inner wall and the outer wall In this way, the entire outer wall and the inner wall are completely separated by the insulation layer, and the insulation effect is good. When making this structure, firstly, the tie parts should be placed horizontally on the insulation layer, and the concrete should be vibrated and compacted to fix the insulation layer. Both sides of the layer, and meet the hardness requirements, but in the process of vibration and compaction, the tie piece will be subjected to downward force, and then the tie piece will press down on the insulation layer below it, because the insulation layer is an elastic material , so that the tie piece has an upward internal stress in the block, resulting in the fact that in the initial stage of block production, when the concrete has not condensed, there is basically no hardness, and the tie piece will bounce up the concrete above it, resulting in self-insulation The breakage of the block has a very high scrap rate. During the use process, the tie parts have internal stress and are easily damaged, resulting in increased costs. The above problems can be better overcome by the way of cast-in-place concrete, but because of the cast-in-place concrete Compared with the way of using vibration extrusion molding machine, it has larger defects;

[0004] 1. The production speed is slow: it is necessary to manually pour the flowable concrete into the block formwork box, wait for the blocks to condense naturally, and remove the formwork box. The production speed is slow and the cycle is long, which cannot meet the production needs;

[0005] 2. Low block strength: Since the cast-in-place concrete cannot be compacted, the density of the block is low, which causes the block to have its own defects. The block has low strength and poor freeze-thaw resistance, which makes it difficult to meet the requirements. Poor building security;

[0006] 3. High cost: the proportion of cement required for cast-in-place concrete is higher than that of vibratory extrusion molding machines, and cement is the most expensive raw material used, resulting in an increase in the cost of blocks

[0007] At the same time, the self-insulating block also has the following problems: the outer wall and the inner wall must be connected with the insulation layer through slots such as dovetail grooves, which causes complicated procedures when processing the block and the insulation layer, and improves the performance of the self-insulation block. Production cost; and when this self-insulating block builds a wall, ash layer connection is required between the blocks in the horizontal direction and between the blocks in the vertical direction, and there is no insulation layer between the ash layers, and the ash layer It constitutes a thermal bridge, resulting in a reduction in the insulation effect.
