Description

An inorganic composite self-insulating sintered shale hollow block/brick

technical field

The utility model relates to a building brick, in particular to an inorganic composite self-insulating sintered shale hollow block/brick.

Background technique

Hollow brick is the main wall material commonly used in the construction industry. Due to its advantages of light weight and low consumption of raw materials, it has become the first product recommended by the national construction department. The porosity of hollow bricks is generally 15%-45%. Compared with solid bricks, hollow bricks can save a lot of land, soil and fuel for burning bricks, reduce transportation weight; reduce labor intensity during brick making and masonry, speed up construction progress; reduce building weight, increase building layers, and reduce construction costs . Advantages of hollow bricks: light weight, high strength, heat preservation, sound insulation and noise reduction performance. Environmentally friendly and pollution-free, it is an ideal filling material for frame structure buildings.

With the implementation of energy saving and environmental protection projects, the thermal insulation performance of the existing hollow bricks is far from meeting the national energy saving and emission reduction requirements. In order to solve the problem of the insulation performance of hollow bricks, those skilled in the art have been making active efforts. For example, Chinese patents have disclosed a number of related patented technologies. However, its energy-saving efficiency is not ideal, the thermal conductivity can only reach about 0.28, and the contradiction between porosity and strength cannot be effectively resolved. There are also whole hollow bricks that are directly made of thermal insulation material, but this makes the cost of the bricks increase and the practicability decreases.

As a new type of building material, foam concrete has good thermal insulation and heat insulation effects. It is also widely used in the current frame structure buildings, mainly for pouring or pouring load-bearing walls. However, in order to save costs, non-load-bearing walls are generally made of bricks, which reduces the heat preservation and insulation effects of the entire house, thereby reducing the energy-saving effect of the house.

Utility model content

In view of the above-mentioned deficiencies in the prior art, the purpose of this utility model is to provide an inorganic composite self-insulating sintered shale hollow block/brick, which can effectively solve the problems of poor heat preservation and energy-saving effects of the existing hollow bricks, and at the same time improve its strength.

In order to achieve the above purpose, the technical solution adopted by the utility model is as follows: an inorganic composite self-insulating sintered shale hollow block/brick, including a load-bearing base and holes; its feature is that the load-bearing base is a sintered shale hollow brick , pouring foam concrete into the hole. Further, the cross section of the hole is rectangular, circular or elliptical.

Compared with the prior art, the utility model has the advantages that the foamed concrete is preferably poured into the holes, and a large number of closed small pores in the foamed concrete improve the thermal performance of the hollow brick, and the strength is higher than that of the same type of hollow brick without foamed concrete, At the same time, it solves the problem of grout leakage when traditional hollow brick walls are built. The utility model has the advantages of simple structure and good heat preservation effect, and its thermal conductivity can reach about 0.23 at the lowest according to the test, which is much better than other brick bodies of the same type.

Description of drawings

Fig. 1 is a schematic cross-sectional view of Embodiment 1 of the present utility model.

Detailed ways

The utility model will be further described below in conjunction with accompanying drawings and embodiments.

Embodiment: Referring to Fig. 1, an inorganic composite self-insulating sintered shale hollow block/brick includes a load-bearing base 1 and a hole 2; the hole 2 is poured with foam concrete. The load-bearing matrix is a sintered shale hollow brick. Foam concrete can be conventional foam concrete.

Further, the insulation effect of the foamed concrete is more obvious by adopting the following formula, using cement, slag, fly ash and foaming agent as raw materials, and its formula is shown in the table below. The porosity is 50-55%, which can better improve the heat preservation effect of bricks. The preferred formula of foam concrete is as follows:

Among them, other fillers include vitrified microbeads, expanded perlite, polystyrene particles or/and lightweight ceramsite, etc.

The foamed concrete 2 is filled into the hole by pouring or pouring, the forming is simpler and more convenient, and the stability between the brick body and the foamed concrete can be ensured, and the strength of the brick body can be increased.

In the utility model, the pouring process of the foamed concrete is mechanical pouring. After the hollow brick comes out of the roasting kiln, it is cooled to below 60°C, the concrete is poured, and the surface is closed by machine.

In addition, according to different needs, the cross section of the hole is rectangular, circular or elliptical.
