Description

The key brick of high attachment structure

Technical field

It the utility model is related to a kind of refractory material, more particularly to a kind of industrial furnace arch with high bonding strength used Dome brick structure.

Background technology

Arch kiln top is kiln roof construction common in industrial furnace, and it is generally built into middle high both sides by some refractory brick Low arch, then be supported on by skew block on stove wall, this arch kiln top built with common refractory brick often due to Significantly expanded with heat and contract with cold caused by the significantly change of temperature in the stove course of work and form the change of planform, kiln is withstood on In the case of expanded by heating, often can because vault by squeeze and caused by vault increase, form between the refractory brick of vault connection contact Situation can be deteriorated, and easily cause the damage on kiln top.In order to change this situation, some manufacturer productions trapezoidal kiln top in section Brick, this ceiling brick need to determine the width of the top and bottom of trapezoid cross section ceiling brick according to the accurate measurement of built stove vault Degree, to be improved to kiln top attachment structure, although this is better than the refractory brick using effect of common cuboid, its Versatility is deteriorated, and special ceiling brick size is determined for each stove, and manufacturing cost is high, and later maintenance is changed and also is difficult to match somebody with somebody To the ceiling brick of same size size.

Utility model content

For the above-mentioned deficiency present in prior art, technical problem to be solved in the utility model is to provide a kind of height The key brick of attachment structure, it is ensured that the stabilization of attachment structure, and there is higher versatility between each other.

In order to solve the above-mentioned technical problem, the key brick of a kind of high attachment structure of the present utility model, including key brick sheet Body, the key brick body includes left surface and right flank, upper side and downside and front and rear end, in left surface and right side Connection tongue-and-groove is respectively arranged with face, connection boss is provided with below front end, connection step groove is provided with below rear end, even It is pluggable in connection step groove to connect boss.

In said structure, because the key brick body includes left surface and right flank, upper side and downside and preceding End and rear end, are connected tongue-and-groove, then this key brick is in substantially hexahedron structure, is being encircleed in left surface with being respectively arranged with right flank When dome brick is built into stove baking top, adjacent two key brick can be by set on left surface and right flank on stove width Socket connection tenon strengthens the attachment structure at the top of stove between each key brick in the connection tongue-and-groove put, and is produced because of temperature change When expanding with heat and contract with cold and causing arch deformation, annexation between each key brick can be by connecting the connection of institute's grafting in tongue-and-groove Tenon keeps relative stability, and by the joint tongue of institute's grafting in connection tongue-and-groove can also obstruct adjacent two key brick between stitch Gap, ensure the sealing between outside at the top of stove, improve the stove thermal efficiency.It is again convex due to being provided with connection below front end Platform, connection step groove is provided with below rear end, connection boss is pluggable in connection step groove, then is built using this key brick During stove vault, can mutually it be overlapped by set connection boss with being connected step groove on stove length direction.So, no Attachment structure stabilization, good airproof performance can be kept only on stove width and on stove length direction, meanwhile, this arch Dome brick need not determine relative dimensions according to stove vault accurate measurement, be adapted to the stove arch of various different specification sizes Top size builds requirement, and structure is versatile.

A kind of preferred embodiment of the present utility model, the left surface are each perpendicular to the upper side with right flank Side.It is versatile using the embodiment, key brick compound with regular structure.

Another preferred embodiment of the present utility model, the left surface and connection tongue-and-groove chi set on right flank Very little identical and with downside distance is equal.Using the embodiment, it is identical to ensure that this key brick can use when building vault Joint tongue, make key brick that there is interchangeability.

Another preferred embodiment of the present utility model, the connection boss are corresponding with the height for connecting step groove. Using the embodiment, it is ensured that connection boss can be overlapped mutually with being connected step groove.

The utility model further preferred embodiment, the connection boss is with being connected the height of step groove equal to described Connect the distance between tongue-and-groove and downside.Using the embodiment, it is easy to manufacture.

Another further preferred embodiment of the utility model, each outer end being provided with the front end of connection boss Surface is vertical with left surface, right flank, upper side and downside；Each outer end table being provided with the rear end of connection step groove Face is vertical with left surface, right flank, upper side and downside.It using the embodiment, can be easy to manufacture, and be easy to use During overlap joint between front and rear adjacent two key brick.
