A kind of hanger brick
Technical field
The present invention relates to a kind of hanger brick.
Technical background
In various boilers, calcining kiln, top refractory brick generally adopts hanger brick to install, if Authorization Notice No. is disclose a kind of Novel multi-purpose boiler hanging brick for the Chinese invention of CN201575473U, including hanger brick body, described hanger brick body is provided with one or more than one annular groove.The hanger brick of this structure fixes adjacent hanger brick by annular groove, and annular groove has relatively thin cell wall, very easily damaged under long-time hot environment, thus causing dropping of hanger brick, and the even total collapse of top hanging brick.
Summary of the invention
The technical problem to be solved is just to provide a kind of hanger brick, and firm stable more after installation, the life-span is higher.
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that
A kind of hanger brick, including female brick and sub-brick, it is protruding that described female brick lower end is provided with extend to both sides respectively first, it is protruding that described first protruding head end is provided with upwardly extending second, described first protruding and the second projection and female brick side form draw-in groove, described sub-brick lower end is provided with the first projection, described first projection is respectively provided on two sides with the second projection, groove is formed between first projection and the second projection, sub-brick is arranged between female brick two pieces adjacent, in second protruding embedding groove, second projection embeds in draw-in groove, first projection is held between adjacent first projection of two female bricks, female brick and sub-brick are respectively equipped with the through hole that can be interconnected, described through hole is provided with fixing bar be connected with sub-brick by mother's brick.
Preferably, the upper end of described female brick is provided with T-slot.
Preferably, described fixing bar is made up of high-temperature alloy steel.
The invention have the benefit that
Sub-brick is fixed between two pieces of female bricks, draw-in groove is embedded by the second protruding embedding groove and the second projection, by firm with female brick clamping for sub-brick, normal refractory brick can be piled up above sub-brick, sub-brick is connected also by fixing bar with female brick, further enhances sub-brick and female brick weight capacity, after the hanger brick of the present invention is installed, not cracky and cause hanger brick to come off, its structure firm stable more.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described further:
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.
As shown in Figure 1, the present invention includes female brick 1 and sub-brick 2, described female brick lower end is provided with the first projection 101 extended respectively to both sides, described first protruding 101 head ends are provided with upwardly extending second projection 102, described first protruding 101 and second protruding 102 forms draw-in groove 103 with female brick side, described sub-brick lower end is provided with the first projection 201, described first projection is respectively provided on two sides with the second projection 202, groove 203 is formed between first projection and the second projection, sub-brick is arranged between female brick two pieces adjacent, in second protruding embedding groove, second projection embeds in draw-in groove, first projection is held between adjacent first projection of two female bricks, female brick and sub-brick are respectively equipped with the through hole 3 that can be interconnected, described through hole is provided with fixing bar be connected with sub-brick by mother's brick.The upper end of described female brick 1 is provided with T-slot 104.Described fixing bar is made up of high-temperature alloy steel.
The installation method of the present invention:
First, the T-slot of female brick is fixed on the prior mounted steel structure connecting member of furnace roof, then sub-brick is positioned between female brick two pieces adjacent, by in the second protruding embedding groove, the second projection embeds in draw-in groove, and the first projection is held between adjacent first projection of two female bricks, now, the through hole of female brick and sub-brick aligns, penetrates fixing bar in through-holes, is connected with sub-brick by mother's brick.
Sub-brick is fixed between two pieces of female bricks, draw-in groove is embedded by the second protruding embedding groove and the second projection, by firm with female brick clamping for sub-brick, normal refractory brick can be piled up above sub-brick, sub-brick is connected also by fixing bar with female brick, further enhances sub-brick and female brick weight capacity, after hanger brick is installed, not cracky and cause hanger brick to come off, its structure firm stable more.
Above preferred embodiment of the present invention is described, but is not to be construed as the restriction to claim.The present invention is not only limited to above example, and its concrete structure allows to change, and those skilled in the art can be variously modified according to the present invention and deform, and without departing from the spirit of the present invention, belongs to the scope that claims of the present invention are defined.
