Description

Anti-seismic insulation blocks

technical field

The utility model relates to the field of construction, in particular to provide an anti-seismic and thermal insulation block with low comprehensive cost, simple and fast construction and excellent comprehensive performance.

Background technique

The traditional brick-concrete building structure in my country generally uses solid clay bricks as the wall, and the frame structure uses lightweight aerated concrete blocks as the filling wall. Because making solid clay bricks will waste a lot of land resources, the national conditions of our country are that there are many people and little land. Land is a non-renewable and scarce resource. Now the country has banned the use of solid clay bricks, allowing the use of hollow clay bricks and aerated concrete blocks. Due to the thin ribs of hollow clay bricks and the poor strength of aerated concrete, the nail holding power is weak. The insulation layer made on the wall made of this material has great potential safety hazards, and durability has always been a bottleneck that plagues its development.

Utility model content

The utility model aims at providing a high-quality, energy-saving and low-cost anti-seismic heat-insulation block aiming at the deficiencies in the above-mentioned background technology.

The technical scheme that the utility model solves its technical problem adopts is:

Earthquake-resistant thermal insulation blocks do not use clay, sand, and stones as aggregates, but use renewable resources such as sintered ceramsite, fly ash, construction waste, chemical and paper industry sedimentation sludge, river sludge, slag, and coal gangue. It has I-shaped side ribs, a groove for placing steel bars on the grouting surface, an insulation cavity in the middle that can be filled with polyurethane hard foam insulation material, an air cavity around the insulation cavity, and a pourable cavity between the air cavity and the air cavity. Three rows of small hollow blocks with upper and lower through holes in the core column cavity of the cementitious material. The weight of the same volume is much lower than that of solid clay bricks, and its frost resistance, impermeability, flexural resistance, and compressive strength are much higher than that of solid clay bricks. The hydrophobic autoclaved three-row hollow through-hole lightweight anti-seismic thermal insulation block meets the national standard.

Building houses with this kind of anti-seismic thermal insulation block not only greatly reduces the amount of clay, sand, cement and other materials, but also reduces the workload and ensures the quality. Because this anti-seismic thermal insulation block also has an air cavity in addition to the thermal insulation cavity, the waterproof, thermal insulation and sound insulation effects are very good. If decoration is required, the interior and exterior walls can be directly constructed without plastering and leveling; since the outer surface of the wall base and the insulation layer are separated by the air cavity of the block, no matter what material is used for the exterior wall decoration No heat collecting effect will occur on the finish. All kinds of pipelines do not need to be embedded, and can be laid directly by using the air cavity. The wall built with anti-seismic and thermal insulation blocks belongs to the assembled integral shear wall structure, and each block has a vertical reinforced concrete core column and horizontal transverse tension steel bars inside, and the reinforced concrete of the wall accounts for 10-30% of the total wall. Its characteristic is that the steel bars in the core column and the groove cover the entire wall, the density of the reinforcement is high, there is no distinction between the tension area and the compression area, and the wall strength is far greater than that of the house with concrete at the inner and outer corners. The walls of the earthquake-resistant structural columns, the overall strength of the building is also greater than the traditional frame structure. The traditional ordinary reinforced concrete structure has more than enough tensile strength and insufficient bending resistance. The wall made of anti-seismic insulation blocks bears all the tensile force, and the bending resistance is borne by the tensile force of its corresponding steel bar. Due to the tensile force of the steel bar The strength is far greater than its flexural strength, so the wall only needs to be equipped with thin steel bars for tensile strength, which greatly saves the amount of thick steel bars; second, the dense reinforcement blocks the radiation of electromagnetic waves like a shielding net, reducing the The harm of electromagnetic waves to the human body; the third is that the floor is integrated with the wall by integral pouring. During the earthquake, the wall is under the bending force under the earthquake level. Since the floor and the wall are a whole, the whole structure has good extensibility and Integrity, compared with the traditional shear wall, the wall has a lower elastic modulus and is more flexible. It has a good energy dissipation capacity to absorb seismic waves in strong earthquakes, and has a large earthquake resistance margin. The joint action of anti-seismic insulation blocks and steel bars can achieve The highest values of compressive, tensile, bending, and shearing resistance meet the structural shockproof level of "not damaged by small earthquakes, repairable by moderate earthquakes, and not collapsed by large earthquakes", so it has very excellent seismic performance. Due to the high cost of the shear wall structure, it is generally only used as a foundation in the basement of high-rise buildings below ± 0, high-rise buildings above ± 0 adopt frame structures, and general buildings adopt brick-concrete structures. Due to the uneven settlement of the building foundation in the traditional building structure, the tension zone and compression zone of the beam and column will change and the wall will crack. Walls and floor slabs will not crack even if the foundation of the house settles unevenly, so the general brick-concrete structure does not need to design concrete seismic structural columns and ring beams, thereby avoiding the design problems of small wall stacks between structural columns and reducing the size of the wall. out-of-plane bending moment. Using this method to build a house saves time, labor, labor and materials, has good effect and high strength, and is easily accepted by the society. Although high-density polyester polyurethane rigid foam and polymer cementitious materials are expensive, most of the construction is mechanized, with a high degree of automation, less labor and no waste of raw materials, so the total construction cost is far lower than traditional shear wall structures and The frame structure will not exceed the total budget for the design and construction of ordinary brick-concrete structure thermal insulation houses, and the construction is simple, beautiful in appearance, high in quality and low in price, and durable; it is a combination of thermal insulation, waterproof, fireproof, sound insulation, bonding, earthquake resistance, and flood resistance. Water resistance, freeze-thaw resistance, fission resistance, aging resistance, wind resistance, radiation resistance, safety performance, and overall performance are all excellent and no later maintenance is required. The anti-seismic thermal insulation block is not only suitable for building load-bearing walls of low-rise buildings, but also suitable for building filling walls of high-rise buildings. It is especially suitable for earthquake and flood disaster area reconstruction.
