Description

A self-insulating block for exterior walls

technical field

The utility model relates to the technical field of buildings, in particular to a self-insulating block used for an outer wall.

Background technique

my country's wall insulation materials started late and have few varieties, which cannot meet the requirements of green energy-saving buildings and sustainable social development. According to the development and demand of building insulation materials and the current situation of the domestic building insulation market, with the development of the economy, global resources are decreasing day by day, and energy has become more and more tense. my country's current energy consumption ranks second in the world. Building energy consumption accounts for 23% of my country's total energy consumption (about 350 million tons of standard coal), and the energy consumption per unit building area is more than three times that of developed countries. It is predicted that by 2020, my country's building energy consumption will reach 1.09 billion tons of standard coal, and at the same time, the urban air pollution index will reach 2-5 times the highest standard announced by the World Health Organization. So far, the existing buildings in cities and towns across the country are close to 20 billion m ² , and the accumulated energy-saving building area is only 1.05 billion m ² , accounting for only about 5%. Therefore, vigorously developing energy-saving housing can not only save energy and protect the environment, but also an important means to achieve the overall goal of national energy conservation and emission reduction, and can also bring many green, healthy and practical benefits to residents.

The state stipulates that before 2010, new buildings in cities above the provincial capital must meet the energy-saving requirement of 50%, and cities in severe cold regions must meet the energy-saving requirement of 65%. According to the relevant provisions of the recently promulgated "Code for Construction Quality Acceptance of Building Energy-saving Projects", since October 1, 2004, construction energy-saving projects that do not meet the specifications cannot pass the acceptance test.

Judging from the existing wall materials, the effect of thermal insulation and energy saving is not ideal. Materials such as cement, slag, and construction waste have a large heat transfer coefficient, and they need to be used as wall materials for thermal insulation. However, whether it is for internal insulation or There are many problems in external heat preservation, especially fire safety, which has many disadvantages, and it is difficult to meet the corresponding heat preservation requirements.

The blocks are piled up to form a wall. In the prior art, the blocks are generally solid, that is, the inner and outer layers are an integrated structure of the same material. In order to achieve the effect of heat preservation, after the wall is built, the wall The outside is bonded with an insulation layer, and then painted with a net, so that the interior can achieve the effect of heat preservation. Due to the need for multiple processes, it has the disadvantages of troublesome construction, high labor intensity, and high cost, especially the bonding insulation material is extremely difficult. It is easy to fall off and has the disadvantage of short service life. The self-insulation of walls is a research subject that has only begun to be paid attention to in recent years. In our country, both internal and external thermal insulation methods have been used, but both methods have disadvantages.

Utility model content

The purpose of the utility model is to solve the shortcomings in the prior art, and propose a self-insulation block for external walls.

In order to achieve the above object, the utility model adopts the following technical solutions:

A self-insulation block for external walls, comprising a rectangular shell, grooves are provided on two adjacent side walls of the rectangular shell, and grooves are provided on the other two adjacent sides of the rectangular shell. Tenons are provided on the wall, a cavity is provided in the housing, and a group of support plates are provided in the cavity, and the support plates divide the cavity into a group of independent sub-cavities, and each sub-cavity is Features a thermal insulation board.

Preferably, the length of the tenons is less than or equal to the depth of the tenon groove, and the width of the tenon is equal to the width of the tenon groove.

Preferably, when building a wall, the tenons and tenons on the two adjacent blocks are mortised and fitted.

Preferably, the insulation boards are arranged in parallel, and the insulation boards are perpendicular to the sides of the casing.

The utility model has the advantages that: the utility model provides a self-insulation block for external walls, which is convenient in construction, durable in use, good in heat preservation effect, durable in use, comprehensively utilizes solid waste, and turns waste into treasure , its social benefits, environmental protection benefits, and economic benefits are also huge. This block can be produced on a large scale and can fully meet market demand.
