Hollow building block

Abstract

The invention discloses a hollow building block. The large hollow building block having a thin thickness is preformed through a step of using broken stones, cobbles, gangues, sands, waste concrete blocks, brick dregs, and various decoration stone leftovers as aggregates, a step of adding certain proportions of cement and fly ash, and a step of mechanically stirring. When a wall is built, a method comprising a step of firstly putting hollow building blocks and secondly pouring a motor is adopted to form a seamless solid wall body, so the strength, the sound insulation and the heat insulation of the wall body are increased; and prime ribs comprising fine moso bamboos, bamboo chips, rattans, wickers and the like can be added into the wall body to form a prime rib wall body, so the tensile strength of the wall body is increased, and the shock resistance of a house is improved.

Description

technical field [0001] The invention relates to a load-bearing wall masonry material for brick-concrete structures. Materials such as gravel, sand, cement, and fly ash are used to make hollow blocks with thin walls. The thin-walled hollow blocks are referred to as Hollow blocks. According to the special structure of the hollow blocks, a new method for wall construction is provided. Background technique [0002] The phrase "Qin bricks and Han tiles" shows that bricks were used to build houses in the Qin Dynasty, and the Great Wall was built with bricks. Today, more than 2,000 years later, we also use bricks to build houses. For a long time, except for some changes in the size of the brick, its shape has not changed, and the brick is a solid rectangle. The standard dimensions of modern bricks are: length 240mm, width 115mm, thickness 53mm. There is no essential change in the construction method of the wall. It is all "spread the mortar first and then put the bricks". grout...

Problems solved by technology

But bricks also have many deficiencies: ①The raw material of bricks is clay. In order to get the soil, a large amount of farmland will be destroyed. In order to protect the cultivated land, the country has taken various measures to limit the production of clay bricks, but with little effect

② During masonry, the mortar cannot completely fill the gaps between bricks. In order to ensure the compactness of the wall, Article 6.2.2 of the National [Code for Acceptance of Construction Quality of Masonry Works] stipulates: "The fullness of the horizontal mortar joints of masonry According to the calculation of the net area, the fullness of the vertical ash joints must not be less than 80%. In actual operation, the fullness of the horizontal ash joints can reach 80%, and it is difficult to reach 60% of the vertical ash joints %, so that there will be many gaps in the wall, which will reduce the load-bearing capacity and thermal insulation performance of the wall
