Abstract

The utility model discloses a special-shaped refractory brick with step folding surfaces, which comprises a brick body. A joint convex rib and a joint groove are respectively arranged on two opposite masonry planes of the brick body, two step surfaces are respectively disposed on the rest two opposite masonry planes of the brick body, the two step surfaces face towards opposite directions, the joint convex ribs are outwards projected semi-cylindrical convex strips, the joint grooves are inwards sunk semi-circular grooves, and the step surfaces are right angle type step surfaces. The special-shaped refractory brick with step folding surfaces has strong joint force, excellent heat preservation and thermal isolation properties, and is simple in structure and convenient in masonry.

Description

Heterotypic fire brick with step folding face

Technical field

The utility model relates to a kind of refratory insulating brick that is used for Thermal Equipment and Industrial Stoves, relates in particular to the improvement of refratory insulating brick appearance structure.

Background technology

Refratory insulating brick in extensive use in all kinds of Thermal Equipments and Industrial Stoves, existing refratory insulating brick is hexahedron structure mostly at right angles, the refratory insulating brick of this structure is when building by laying bricks or stones mutually, each surface of refratory insulating brick is the plane, thereby no matter be that opposite joint is built by laying bricks or stones or the fissure of displacement is built by laying bricks or stones, the brickwork joint between brick and the brick is vertical masonry joint.Therefore with the refractory wall at existing fire-resistant brick base, poor in conjunction with adhesive property, brickwork joint produce to expand or shrinks and very easily go out crackle in high temperature or cooling procedure, not only the radiation loss of stove is big, also is difficult to block thermal source and sews to exosmosis, and heat insulation and preservation effect is poor, be unfavorable for energy-saving heat preserving, but also, cause the stove can't operate as normal very easily because of frequent expansion with shrink the slippage cause laying bricks and drop, bring very big economic loss to enterprise.Promptly use such refractory brick to carry out building by laying bricks or stones of multilayer, to reach the purpose that increases its insulation and integral rigidity by increase stove wall thickness, but since wall layers with layer between bonding still be vertical masonry joint, can not fundamentally improve the globality of its heat preservation and insulation and stove.

The utility model content

At the above-mentioned deficiency of existing in prior technology, technical problem to be solved in the utility model provides a kind of heterotypic fire brick with step folding face that adhesion is strong, thermal and insulating performance is excellent of building by laying bricks or stones.

In order to solve the problems of the technologies described above, a kind of heterotypic fire brick with step folding face of the present utility model comprises the brick body, is respectively arranged with on the plane in two relative building by laying bricks or stones of described brick body and engages convex tendon and engagement grooves; The brick body in addition two relative building by laying bricks or stones be provided with step surface on the plane, this two step surface towards on the contrary.

After adopting said structure, owing to be respectively arranged with joint convex tendon and engagement grooves on the plane in two relative building by laying bricks or stones, when refractory brick is built by laying bricks or stones, this relative two is built joint convex tendon on the plane by laying bricks or stones and is meshing with each other with engagement grooves and is connected, thereby strengthened the adhesion between brick and the brick effectively, make the integral rigidity of kiln wall greatly improve, not being prone to lays bricks comes off long service life.This structure makes that also build vertical masonry joint by laying bricks or stones becomes and build the curve seam by laying bricks or stones simultaneously, and effectively the seepage that leaks of blocking heat source has desirable heat insulating effect.Again because at brick body two relative step surfaces that are provided with on the plane towards opposite of building by laying bricks or stones in addition, believing when building by laying bricks or stones that last this two relative step surface of laying bricks docks engagement mutually, it is the curve seam that the vertical masonry joint of original structure is become, thus bonding stability and heat insulating effect between the fragment of brick on the other direction of further having strengthened laying bricks.Adopt laying bricks of said structure, what body of wall had an enhancing on a plurality of directions builds adhesion and good heat preservation and insulation by laying bricks or stones, has not only made things convenient for the base of fragment of brick to build, and strengthens the rigidity and the stability of wall, and has superior thermal efficiency.The refractory brick of this structure also has makes simply advantage easy to use.

A kind of preferred implementation of the present utility model, described step surface are the perpendicular type step surface.This structure is convenient to make and build by laying bricks or stones.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the schematic diagram of the main TV structure of a kind of specific embodiment of the present utility model;

Fig. 2 is the right TV structure schematic diagram of structure shown in Figure 1;

Fig. 3 is the left TV structure schematic diagram of structure shown in Figure 1.

Among the figure, 1-brick body, 2-engages convex tendon, 3-engagement grooves, 4-step surface.

The specific embodiment

Roll in the heterotypic fire brick of face at Fig. 1, Fig. 2 and the step that has shown in Figure 3, forward and backward two relative building by laying bricks or stones at the brick body are respectively arranged with joint convex tendon 2 and engagement grooves 3 on the plane, this joint convex tendon 2 is the semi-cylindrical cord tissue of evagination, engagement grooves 3 is the semicircle shape groove of indent, the cross sectional shape that engages convex tendon 2 and engagement grooves 3 matches, so that closely mesh bonding when brick and brick are built by laying bricks or stones mutually.This cross sectional shape that engages convex tendon 2 and engagement grooves 3 can also be trapezoidal except that circle, other geometry such as triangle.

Two relative bricks in addition at brick body 1 are built the step surface 4 that is provided with perpendicular type on the plane, this step surface 4 towards opposite and measure-alike, so that when building by laying bricks or stones, mesh bondingly between laying bricks interlacedly, it is the broken line seam that connection seam between fragment of brick is become by the straight line seam.This step surface and joint convex tendon and engagement grooves exist equally, have greatly strengthened adhesion and fire resistant heat preserving performance between laying bricks.
