Description

Technical Field

[0001] This application relates to the field of municipal building wall technology, and in particular to a self-insulating green block masonry structure for municipal walls based on construction waste. Background Technology

[0002] With the acceleration of urbanization, the amount of waste generated by the construction industry has increased dramatically. The indiscriminate dumping of large amounts of construction waste not only occupies land resources but also causes serious environmental pollution, which is inconsistent with the concept of green and environmentally friendly development. At the same time, in the construction of municipal walls, traditional wall blocks often have problems such as poor thermal insulation performance, insufficient structural stability, and low construction efficiency.

[0003] Currently, some masonry blocks made from construction waste are used in municipal walls. However, the existing block structures are relatively simple, mostly achieving basic wall construction functions through a single block body. Their self-insulating performance is insufficient to meet the energy-saving and insulation requirements of municipal walls. Typically, an additional insulation layer needs to be added after the wall is built. This not only increases construction steps and costs but may also lead to problems such as insulation layer detachment and wall cracking due to weak bonding between the insulation layer and the block body, affecting the overall service life and safety of the wall. Furthermore, the existing connection structure design between blocks is unreasonable, easily leading to misalignment and displacement during construction, reducing the structural stability and overall strength of the wall, making it difficult to meet the high standards of structural performance required for municipal walls.

[0004] Therefore, developing a municipal wall block masonry structure that can effectively utilize construction waste while possessing excellent self-insulating properties and reliable structural stability has become an urgent problem to be solved in the current municipal construction field.

[0023] See Figure 1-2 The aforementioned municipal wall self-insulating green block masonry structure based on construction waste includes green block unit 1, which is assembled vertically, horizontally, and vertically to form a municipal wall. Green block unit 1 includes: The block body 11 is made of recycled aggregate from construction waste, cement, fly ash and additives. Insulation cavities 12 are evenly opened in the block body 11 along its length. The insulation cavities 12 are filled with insulation material. Adjacent block bodies 11 are interlocked. Insulation reinforcement layers 17 are provided on both the front and rear sides of the block body 11.

The gaps between two adjacent green block units 1 arranged side by side are filled with sealant, and the gaps between two adjacent green block units 1 arranged vertically are filled with fireproof sealing strips.

[0024] Specifically, the thermal insulation reinforcement layer 17 is a vacuum insulation board or aerogel insulation felt, with a thickness of 5-15mm. The bonding layer is a polymer cement mortar bonding layer, with a thickness of 2-5mm. The protective layer 18 is a crack-resistant mortar protective layer, with a thickness of 3-8mm, and contains alkali-resistant glass fiber mesh, which effectively protects the thermal insulation reinforcement layer 17 and prevents it from being damaged during construction or use.

The recycled aggregate accounts for 40%-60% of the mass of the block body. Admixtures include water-reducing agents, air-entraining agents, and early-strength agents. The amount of water-reducing agent added is 0.5%-1.5% of the cement mass, and the amount of air-entraining agent added is 0.01%-1.5% of the cement mass. 0.03%, wherein the amount of the early strength agent added is 1%-3% of the cement mass.

[0025] In some embodiments, the top of the block body 11 is provided with parallel protruding ridges 13 along its length, and the bottom of the block body 11 is provided with grooves 14 that are adapted to the protruding ridges 13 along its length. Adjacent green block units 1 arranged vertically are engaged by the cooperation of the protruding ridges 13 and the grooves 14. Two first connecting blocks 15 are provided on the left side of the block body 11, and the two first connecting blocks 15 are arranged symmetrically. Two first connecting slots 16 that are adapted to the first connecting blocks 15 are provided on the right side of the block body 11. Adjacent green block units 1 arranged horizontally are engaged by the cooperation of the first connecting blocks 15 and the first connecting slots 16.

[0026] Specifically, adjacent green block units 1 are connected by the cooperation of the protruding ridge 13 and the groove 14, and the first connecting block 15 and the first connecting groove 16. This connection method can effectively improve the connection stability between adjacent block units 1, prevent misalignment and displacement during the construction process, and improve the overall structural strength and deformation resistance of the wall, ensuring that the wall has reliable structural stability and extending the service life of the wall.

[0027] See Figure 3 In some embodiments, the device also includes an adapter adjustment block 2, which is a strip structure. One side of the adapter adjustment block 2 is provided with a second connecting groove 19 that is adapted to the first connecting block 15, and the other side is provided with a second connecting block 110 that is adapted to the first connecting groove 16. The adapter adjustment block 2 is also provided with a heat insulation cavity 12. The front and rear sides of the adapter adjustment block 2 are provided with a heat insulation reinforcement layer 17 and a protective layer 18 of the same specifications as the front and rear sides of the block body 11.

[0028] Specifically, when the width of the municipal wall needs to be adjusted at the edge, the size can be adapted by splicing the adapter adjustment block 2 with the standard green block unit 1. The length of the adapter adjustment block 2 can be set to 1 / 2, 1 / 3 or 1 / 4 of the length of the standard green block unit 1 according to actual needs. In this embodiment, the length of the adapter adjustment block 2 is 1 / 2 of the length of the standard green block unit 1. The adapter adjustment block 2 also has an insulation cavity 12 inside. The front and rear sides of the adapter adjustment block 2 are provided with insulation reinforcement layer 17 and protective layer 18 of the same specifications as the front and rear sides of the block body 11, to ensure that the insulation performance and structural strength of the edge part are not lower than those of the main body of the wall.

[0029] See Figure 4 In some embodiments, the block body 11 is further provided with a layered waterproofing and drainage structure, which includes: Inner waterstop strip 111: The inner waterstop strip 111 is set at the joint of the protrusion 13 and groove 14 of the adjacent green block unit 1 above and below, and at the joint of the first connecting block 15 and first connecting groove 16 of the adjacent green block unit 1 on the left and right. The inner waterstop strip 111 is made of water-swellable rubber. Middle layer guide channel 112: The middle layer guide channel 112 is opened at the top of the block body 11 along the length direction of the block body 11, located between the two protruding ridges 13, and has a "V" shaped structure. The two ends of the middle layer guide channel 112 extend to the left and right side walls of the block body 11. Outer waterproof coating 113: The outer waterproof coating 113 is disposed on the side of the protective layer 18 away from the block body 11.

[0030] Specifically, the inner waterstop strip 111 is made of water-swellable rubber. When rainwater seeps into the gap, the inner waterstop strip 111 expands and seals the gap, preventing further water penetration. When rainwater seeps into the middle layer, it can be guided to the outside of the block through the middle layer guide channel 112, preventing water from remaining inside the block. The outer waterproof coating 113 is a polyurea waterproof coating with a thickness of 2-4mm. The surface of the coating has a textured surface to enhance the water diversion effect and improve the weather resistance and anti-aging properties of the wall surface.

[0031] The inner layer of water-swellable sealing strip, the middle layer of V-shaped drainage channel, and the outer layer of polyurea waterproof coating form a layered waterproof system that prevents rainwater penetration from three dimensions: "blocking, guiding, and preventing," achieving all-round sealing. This effectively solves the problems of traditional walls being prone to water seepage and insulation materials failing due to moisture, enabling the wall's waterproof rating to reach P6 or higher and extending its service life by 10-15 years.

[0032] In some embodiments, the cross-sections of the protruding ridge 13, the groove 14, the first connecting block 15, and the first connecting slot 16 are all trapezoidal structures.
