Description

Technical Field

[0001] This utility model relates to the field of construction, and more specifically, to a composite thermal insulation block. Background Technology

[0002] Composite insulation blocks are a new type of building wall material that integrates load-bearing and insulation functions. They are widely used in the field of building energy conservation. By combining insulation materials with traditional blocks, they improve the insulation performance of wall structures and meet the requirements of modern buildings for energy conservation and environmental protection. Insulation materials generally include polystyrene foam (EPS), rock wool, polyurethane, etc.

[0003] Sandwich composite insulation blocks are one of the most common types of composite insulation blocks we see every day. The inner and outer layers are made of concrete, with insulation material sandwiched in between. The insulation blocks are stacked in a triangular pattern to form an insulation wall. During the stacking process, the blocks need to be cut. However, compared to ordinary aerated concrete blocks, composite insulation blocks are more difficult to cut. The difficulty lies in the fact that the insulation material in the middle layer usually has high toughness or elasticity. In particular, the organic insulation components in it will "stick" to the cutting tool, resulting in increased cutting resistance. Unlike concrete layers, which, although hard, are brittle and easy for the tool to cut into and break the material, the resistance is relatively small.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a composite thermal insulation block.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a composite thermal insulation block, comprising a brick body, the brick body comprising an inner layer, an outer layer and a thermal insulation layer, the thermal insulation layer being sandwiched between the inner layer and the outer layer, the thermal insulation layer being composed of a plurality of thermal insulation blocks, gaps existing between adjacent thermal insulation blocks, an injection groove being provided at the edge of the thermal insulation block, an injection strip being formed in the injection groove connecting the inner layer and the outer layer, and a dividing groove being provided on the injection strip above the gap.

[0007] The present invention is further configured such that: each of the insulation blocks has a locking wing on both sides, the cross-section of the locking wing is an isosceles trapezoid, the width of the locking wing is smaller as it gets closer to the insulation block, and the inner and outer layers each have a locking groove for embedding the locking wing on their opposite sides.

[0008] The present invention is further configured such that: the dividing groove includes a middle groove, and the distance from the middle groove to both sides of the brick body is equal.

[0009] The present invention is further configured such that the depth of the intermediate groove is greater than the depth of the other dividing grooves.

[0010] The present invention is further configured such that: a feedback hole is provided on each of the inner and outer layers facing away from each other, the feedback hole is located directly below the dividing groove, and the distance from the feedback hole to one side of the brick is equal to the thickness of the grouting strip.

[0011] The present invention is further configured such that the insulation layer is made of PU material.

[0012] In summary, this utility model has the following beneficial effects:

[0013] When people need to cut bricks, they place the cutting tool into the dividing groove and then cut downwards. The cutting tool will cut the grouting strip and directly enter the gap between two adjacent insulation blocks, so that it is not easily affected by the insulation layer during the cutting process. In the end, it is still the inner and outer concrete layers that are cut, which makes it easier for people to cut the insulation blocks. The setting of the grouting strip provides concrete space for the dividing groove, making the structure of the dividing groove more stable, and at the same time increasing the connection strength between two adjacent insulation blocks.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Composite insulation blocks, such as Figure 1 and Figure 2As shown, the brick body includes an inner layer 1, an outer layer 2, and an insulation layer. The insulation layer is sandwiched between the inner layer 1 and the outer layer 2. The insulation layer is composed of several insulation blocks 3, with gaps between adjacent insulation blocks 3. A grouting groove 4 is formed at the edge of each insulation block 3, and a grouting strip 9 connecting the inner layer 1 and the outer layer 2 is formed within the grouting groove 4. A dividing groove 8 is provided on the grouting strip 9 above the gaps. When it is necessary to cut the brick body, a cutting tool is placed into the dividing groove 8, and then cut downwards. The cutting tool will cut through the grouting strip 9 and directly enter the gap between two adjacent insulation blocks 3. This design minimizes the impact of the insulation layer during the cutting process. The overall cutting involves the inner layer 1 and the outer layer 2 of concrete, making it easier for people to cut the insulation blocks. The grouting grooves 4 on two adjacent insulation blocks 3 are spliced ​​together to form a groove. After the insulation layer is clamped and fixed between the inner layer 1 and the outer layer 2, concrete material is added into the groove formed by splicing the two grouting grooves 4. The concrete solidifies to form a grouting strip 9. The grouting strip 9 is designed to provide concrete space for the dividing groove 8, making the structure of the dividing groove 8 more stable and increasing the connection strength between two adjacent insulation blocks 3.

[0019] like Figure 1 and Figure 2 As shown, each insulation block 3 has a locking wing 5 on both sides. The cross-section of the locking wing 5 is an isosceles trapezoid. The width of the locking wing 5 is smaller as it gets closer to the insulation block 3. The inner layer 1 and the outer layer 2 have slots for embedding the locking wing 5 on their opposite sides. When assembling the brick, people insert the two locking wings 5 ​​of the insulation block 3 into the inner layer 1 and the outer layer 2 respectively, and then use adhesive to bond them together. The setting of the locking wing 5 increases the connection strength between the insulation block 3 and the brick as a whole. The dividing groove 8 includes a middle groove 6. The distance from the middle groove 6 to both sides of the brick is equal. The middle groove 6 is one of the dividing grooves 8. Since the middle position is the commonly used cutting position of the brick, most cutting is done in the middle. Therefore, the depth of the middle groove 6 is greater than the depth of other dividing grooves 8, making the position of the middle groove 6 easier to distinguish and easier to cut than other grooves.

[0020] like Figure 2 As shown, feedback holes 7 are provided on the opposite sides of the inner layer 1 and the outer layer 2. The feedback holes 7 are located directly below the dividing groove 8. The distance from the feedback hole 7 to one side of the brick is equal to the thickness of the grouting strip 9. When cutting with a cutting tool, the tool can cut to the position of the feedback hole 7, indicating that the cutting tool has completely cut the grouting strip 9. At this time, the tool can choose to cut the inner layer 1 and the outer layer 2 separately, which is less strenuous than cutting the brick at the same time and is suitable for people with less strength. The setting of the feedback hole 7 provides a certain amount of feedback, indicating that the grouting strip 9 has been cut. The insulation layer is made of PU material, which is polyurethane foam. It has the characteristic of low thermal conductivity, thus ensuring the overall insulation effect of the insulation layer.

[0021] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
