Novel sand lime brick with fire-resistant effect

Abstract

The invention discloses a novel sand lime brick with a fire-resistant effect. The novel sand lime brick comprises a main brick body, a second brick body and a third brick body, wherein the main brickbody is integrally of a flat cuboid structure; a first notch and a second notch are respectively reserved in positions, near the two sides, of the lower surface of the main brick body; the first notchand the second notch are in symmetrical distribution by using a perpendicular bisector of the main brick body in the length direction as the symmetry axis; two strip-shaped grooves penetrating through the two ends are formed in the front side of the main brick body; the front side of the main brick body is sequentially divided into three parts by the two strip-shaped grooves; through holes are formed in positions, near the two sides, of the groove bottom of the strip-shaped grooves; the distance between the two through holes in the same strip-shaped groove equals to the distance between the first notch and the second notch; and a pressure sensor is clamped and connected into one through hole. The novel sand lime brick has the advantages that the bonding capability between the surface of the sand lime brick and slurry is improved; the falling of possibly little surface slurry under the strong fire baking condition is further ensured; and the connection between fire-resistant bricks isprotected.

Description

technical field [0001] The invention relates to the technical field of refractory bricks, in particular to a novel lime-sand brick with refractory function. Background technique [0002] Traditional building bricks are cuboid bricks with six plane faces. The bricks are bonded together by cement mortar. The bonding force between bricks and cement mortar is low, and the friction between adjacent bricks is small. , the masonry effect is not ideal, and its bonding strength depends entirely on the strength of the bonding material; the wall built with bricks of this structure can bear the pressure in the vertical direction, but lacks the force in the horizontal direction. Sufficient strength; when the wall is used for a certain period of time, under the influence of environmental and climatic conditions, the bonding material will age, which will directly reduce the bonding strength of the wall and seriously endanger the safety of people's lives and property. The main problems of ...

Problems solved by technology

[0002] Traditional building bricks are cuboid bricks with six plane faces. The bricks are bonded together by cement mortar. The bonding force between bricks and cement mortar is low, and the friction between adjacent bricks is small. , the masonry effect is not ideal, and its bonding strength depends entirely on the strength of the bonding material; the wall built with bricks of this structure can bear the pressure in the vertical direction, but lacks the force in the horizontal direction. Sufficient strength; when the wall is used for a certain period of time, under the influence of environmental and climatic conditions, the bonding material will age, which will directly reduce the bonding strength of the wall and seriously endanger the safety of people's lives and property. The main problems of sand bricks include: first, unreasonable grading and unscientific ratio of sand and gravel particles in terms of raw materials; High temperature and high pressure curing, but the temperature, pressure and time control are not standardized, so that the quality of the brick body cannot meet the requirements for use, which brings serious hidden dangers to production safety
