Description

A kind of refractory brick dome structure of locking structure

technical field:

The utility model relates to the fireproof construction field of industrial furnace, particularly relates to a kind of refractory brick dome structure of locking structure.

background technology:

Industrial Stoves and Thermal Equipment are normally built by laying bricks or stones form by being had fire-resistant and fragment of brick that is heat-insulating property, and its top common structure is domeshape and flat-top shape, wherein domeshape structure because of its structure simple, easy to implement and aborning have application more.Existing vault construction is made up of (key brick is also referred to as dome brick) skew block and key brick two parts, it is overall structure brick that skew block has sloping bearing surface, it is directly built by laying bricks or stones on kiln body and Thermal Equipment both sides body of wall as the supporting to key brick, key brick builds up bridge arch shape by polylith is brick, and the two ends of its arch are supported on skew block sloping bearing surface respectively.There are though this Thermal Equipment of dome-shaped top surface and Industrial Stoves can realize the heat treatment of product and fire, but because skew block is overall structure brick, it directly builds by laying bricks or stones on wall body brick face, external force is not had to carry out anti-skidding restriction to it in the horizontal direction, it has trend of moving pushed outwards under the horizontal component effect of arch top, in addition expansion can be produced because of heat in key brick in hot conditions, this just exacerbates the extruding of key brick to skew block, horizontal thrust suffered by skew block is greatly increased, when this horizontal thrust is greater than the intrinsic static friction force of skew block, the sideslip along wall body brick face will be there is and cause vault sinking to ftracture in skew block, heat so not only in kiln and Thermal Equipment can scatter and disappear in a large number, thermal losses is caused to become large thermal efficiency step-down, and when skew block sideslip displacement is excessive, also can produce key brick to drop, also can there is vault time serious to subside, serious affect the service life of kiln and normally carrying out of production.Therefore obviously there is structural defect in this integrally-built skew block, do not have opposing horizontal thrust and stop it to produce the ability of breakking away.In addition, the bricklaying surface of traditional key brick is smoothly, and workman needs to install template in building process, wastes time and energy.

utility model content:

The purpose of this utility model is exactly to solve existing issue, and a kind of refractory brick dome structure of locking structure is provided, whole refractory brick dome structure is made to have coupling mechanism force, good airproof performance, more sturdy and durable, and workman when building by laying bricks or stones and remove all without the need to installing template, construct simple and convenient, reduce workload.

Technology solution of the present utility model is as follows:

A kind of refractory brick dome structure of locking structure, include the skew block being positioned at two ends, dome brick has been built by laying bricks or stones between the skew block at described two ends, described dome brick masonry forms the arch raised up, face of bonding between described skew block and dome brick and the face of bonding between dome brick and dome brick are step surface, step surface projection section on described skew block is positioned at the below in the face of bonding, and the corresponding face of bonding of described dome brick two is parallel to each other.

As preferably, brick plate has been built by laying bricks or stones below described skew block, the length of described brick plate is longer than skew block length and brick plate one end extends to below dome brick, described brick plate is positioned at below dome brick and has built reinforcing brick by laying bricks or stones, described reinforcing brick side is built by laying bricks or stones with skew block and is connected, and its end face and bottom surface are built by laying bricks or stones with dome brick and brick plate respectively and be connected.

As preferably, the height h of described step surface projection section is 1/15 ~ 1/10 of the whole height H of dome brick.

As preferably, the thickness of described reinforcing brick masonry is B, and the thickness of described dome brick is b, wherein b < B < 2b.

As preferably, described dome structure mid portion is moldable.

The beneficial effects of the utility model are:

Face of bonding between the skew block of the utility model structure and dome brick and the face of bonding between dome brick and dome brick are step surface, whole refractory brick dome structure is made to have coupling mechanism force, good airproof performance, more sturdy and durable, and workman when building by laying bricks or stones and remove all without the need to installing template, only need rely on step surface, construct simple and convenient, reduce workload.

accompanying drawing illustrates:

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model dome brick structure schematic diagram.

In accompanying drawing: 1, skew block; 2, dome brick; 3, step surface; 4, brick plate; 5, brick is reinforced; 6, moldable.

detailed description of the invention:

As shown in Figure 1-2, a kind of refractory brick dome structure of locking structure, include the skew block 1 being positioned at two ends, dome brick 2 has been built by laying bricks or stones between the skew block 1 at described two ends, the arch being formed and raise up built by laying bricks or stones by described dome brick 2, face of bonding between described skew block 1 and dome brick 2 and the face of bonding between dome brick 2 and dome brick 2 are step surface 3, and step surface 3 projection section on described skew block 2 is positioned at the below in the face of bonding, and the corresponding face of bonding of described dome brick 2 two is parallel to each other.

Particularly, brick plate 4 has been built by laying bricks or stones below described skew block 1, the length of described brick plate 4 is longer than skew block 1 length and brick plate 4 one end extends to below dome brick 2, described brick plate 4 is positioned at below dome brick 2 and has built reinforcing brick 5 by laying bricks or stones, described reinforcing brick 5 side is built by laying bricks or stones with skew block 1 and is connected, its end face and bottom surface are built by laying bricks or stones with dome brick 2 and brick plate 4 respectively and are connected, and this reinforcing brick 5 of increase makes whole dome structure more firm, and physical life is longer.

Particularly, the height h of described step surface 3 projection section is 1/15 ~ 1/10 of the whole height H of dome brick 2, if projection section height h is too low, then mutual coupling mechanism force can be affected, and affects firmness after coupling mechanism force diminishes, if projection section height h is too high, then have during the structure of radian and be connected inappropriate building some by laying bricks or stones, cause to build by laying bricks or stones and be difficult to hold, and once radian is slightly large, also can affect coupling mechanism force and support force.

Particularly, the thickness that described reinforcing brick 5 is built by laying bricks or stones is B, the thickness of described dome brick 2 is b, wherein b < B < 2b, if the thickness that reinforcing brick 5 is built by laying bricks or stones is that B is excessive, then can affect the free space of heating furnace, also easily non-uniform temperature is caused, if the thickness that reinforcing brick 5 is built by laying bricks or stones is that B is too small, then support force is inadequate, DeGrain.

Particularly, described dome structure mid portion is moldable 6, conveniently builds connection by laying bricks or stones to two faces that dome brick 2 is not fitted.

The foregoing is only preferred embodiment of the present utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all should belong to the scope of the utility model protection.
