Technical Field

[0001] The utility model relates to a composite sandwich insulation wall of recycled antique bricks and aerated blocks, belonging to the field of building construction. Background Art

[0002] At present, urban renewal has entered a period of great development, and the requirements for energy conservation and environmental protection are becoming more and more prominent. For the exterior walls of buildings in the historical style area of ​​the city, they must not only meet the architectural style requirements of the historical style area, but also be energy-saving and environmentally friendly, and at the same time, they should have good structural safety performance. The traditional thermal insulation and decorative integrated wall is an exterior wall system that integrates the insulation layer and the decorative layer. The exterior wall finish is usually connected by adhesion using paint, tiles, stones, cultural stones, etc., which has poor durability and is easy to crack and fall off. Long-term use affects the thermal insulation performance, and there are problems in stability and safety. This type of wall cannot meet the needs of the exterior walls of buildings in the historical style area. For this reason, the antique decorative brick wall is used as the exterior wall, the aerated block brick wall is used as the inner page wall, and the rock board wool and air are sandwiched in the middle as the insulation layer. The composite is compounded through the connector and the composite wall is adopted to improve the integrity of the decorative layer and the structural insulation layer, while ensuring the thermal insulation performance of the wall. Utility Model Content

[0003] The utility model aims to solve the problem that the exterior facing is not firmly connected and is easy to age and fall off in the existing thermal insulation and decoration integrated exterior wall system, and solves the problem that the insulation layer is affected by the external environment and has a short lifespan. A composite sandwich insulation wall of recycled antique bricks and aerated blocks is provided.

[0004] The utility model adopts the following technical solutions:

[0005] The composite sandwich insulation wall of recycled antique bricks and aerated blocks provided by the utility model comprises an inner leaf wall of recycled antique bricks, an inner leaf wall of aerated blocks, and a rock wool insulation board;

[0006] The recycled antique brick inner leaf wall is arranged in parallel with the aerated block inner leaf wall, and a rock wool insulation board is provided on one side of the aerated block inner leaf wall facing the recycled antique brick inner leaf wall; an air layer is reserved between the rock wool insulation board and the recycled antique brick inner leaf wall.

[0007] The antique brick inner leaf wall is built with antique bricks of size 210*100*30mm. The thickness of brick joint mortar is greater than the diameter of the full-length steel bar. The specific I-shaped pattern is used for masonry. The antique brick wall is built with transverse full-length anchor bars in the brick mortar joints every 5 to 6 bricks (about 438 per meter). The transverse full-length steel bars are connected to the tie bars with higher strength. The tie bars extend out of the wall and are connected to the insulation layer and the base aerated block wall at the same time.

[0008] The inner aerated block wall is constructed with aerated blocks sized 600*200*200mm, and the mortar thickness of the brick joints is greater than the lengthwise steel bars inside the aerated block wall; for the antique brick wall, horizontal through-length anchor bars with a diameter are set in the aerated block mortar joints every 5 to 6 courses of bricks. Horizontal through-length tie bars are connected with tie bars of higher strength every 500mm. The tie bars extend out of the wall from the brick joints of the blocks and are connected to the insulation layer and the antique brick wall of the exterior finish at the same time.

[0009] In the composite sandwich insulation wall of recycled antique bricks and aerated blocks of the present utility model, the inner wall of recycled antique bricks is provided with lengthwise steel bars for the antique brick wall;

[0010] The inner aerated block wall is provided with lengthwise steel bars for the aerated block wall;

[0011] Between the lengthwise steel bars for the antique brick wall and the lengthwise steel bars for the aerated block wall are connected by Z-shaped steel bars. Connected to the lengthwise steel bars inside the antique brick wall and the lengthwise steel bars inside the aerated block wall, in order to increase the area of the welding points, Z-shaped tie bars are used. Z-shaped tie bars should select steel bars with higher flexural strength to ensure the stability of the wall after compounding. When using Z-shaped steel bars, the Z-shaped steel bars need to meet the requirements of appropriate bending.

[0012] In the composite sandwich insulation wall of recycled antique bricks and aerated blocks of the present utility model, a special interface agent, a cement mortar leveling layer, and a special adhesive are arranged in sequence on the bonding surface between the inner aerated block wall and the [relevant part]. The rock wool insulation board is fixed on the bonding surface of the inner aerated block wall through a special adhesive; on one end surface of the rock wool insulation board facing the inner wall of recycled antique bricks, an anti-seepage and anti-leakage mortar layer is arranged, and the anti-seepage and anti-leakage mortar layer is in contact with the reserved air layer.

[0013] In the composite sandwich insulation wall of recycled antique bricks and aerated blocks of the present utility model, the rock wool insulation board is fixedly connected to the aerated block brick wall through disc anchor bolts; the disc bolts penetrate into the inside of the inner aerated block wall. The depth of anchoring into the base aerated block wall is not less than 30mm.

[0014] As a preferred solution, a post-embedded plate is arranged at the end position of the antique brick wall surface. A through-length supporting steel plate with a thickness of 10 and a width of 180mm is used. The steel plate is coated with epoxy selenium-rich paint for rust prevention treatment. Two M12 post-inserted undercut mechanical anchor bolts are placed every 500mm on the plate to play a connecting role.

[0015] As a preferred solution, after the aerated block wall is constructed, a special interface agent mainly made of vinyl acetate and ethylene is applied in one coat.

[0016] As a preferred solution, the surface smoothness of antique bricks and aerated concrete blocks is different, and the water absorption capacity of the blocks is different. Different mortar ratios are used for the inner and outer leaves of the composite wall. For the antique brick curtain wall on the outer wall, 32.5-grade ordinary portland cement and medium sand in mixed sand are used, where the ratio of machine-made sand to extra-fine sand is 3:7 and the powder content of machine-made sand is low. M10 cement mortar is used for masonry below elevation ±0.000, and M7.5 mixed mortar is used for masonry above ±0.000. The mortar mix ratio is by weight, and the metering accuracy is: ±2% for cement, and ±5% for sand and admixtures. Water the bricks one day before construction to keep the moisture content at 10% - 15%. Aerated concrete blocks have strong water absorption, and the mortar consistency is 60 - 80 mm. Moisten the bricks moderately 1 - 2 days in advance before construction, and control the moisture content at 30% - 40%.

[0017] As a preferred solution, a layer of alkali-resistant fiberglass mesh cloth is pressed into the polymer waterproof mortar to improve the abilities of heat preservation, waterproofing, crack resistance, sound insulation, etc.; the leveling layer on the inner side of the insulation layer is laid with dry-mixed ordinary waterproof cement mortar. Beneficial effects

[0018] The composite sandwich thermal insulation wall made of recycled antique bricks and aerated concrete blocks provided by the present utility model has a special polymer anti-seepage and leak-proof mortar and a special adhesive sandwiched between the antique bricks and the aerated concrete blocks, making up for the shortcoming of the rock wool board in the wet state and ensuring the bonding quality between the waterproof layer and the thermal insulation layer, and between the thermal insulation layer and the aerated concrete block wall. It solves the problem that the decorative surface layer of the traditional integrated thermal insulation and decoration external wall is easy to fall off, forms a more integral and stable external wall system, reduces the risk of the thermal insulation layer being exposed to the external environment, and increases the service life of the thermal insulation wall.

[0019] For the composite sandwich thermal insulation wall made of recycled antique bricks and aerated concrete blocks provided by the present utility model, the connection method forms a tie piece through steel bar welding. The steel bars are buried longitudinally in the brick joints of the antique brick wall and fixed by I-shaped steel bars in the aerated concrete block wall, making the connection more firm. On the basis of the adhesion of the interface agent and cement mortar, the thermal insulation layer and the aerated concrete block wall are fixed by disc bolts, making the composite wall more integral in structure.
