[0030] Reference Figures 1-5The utility model discloses a first embodiment, a kind of refractory brick of combined masonry, it includes brick main body 10, the first recess 31, the second recess 32 and positioning strip 40 are provided on the brick main body 10, seat 20, seat 20 is arranged at the front end of brick main body 10, first positioning block 21 is provided at the front side of seat 20, the first recess 31 is arranged at the rear end of brick main body 10, the depth of first recess 31 is less than the thickness of first positioning block 21, the second recess 32 is arranged at the rear end of brick main body 10, the rear end of brick main body 10 is provided with the notch 321 that intercommunicates the side wall of first recess 31 and the side wall of second recess 32, positioning strip 40 is arranged in second recess 32, and positioning strip 40 is located the outside of notch 321, the front end of positioning strip 40 is fixedly connected with the inner surface of second recess 32, and the upper and lower sides and the left and right sides of positioning strip 40 are spaced apart from the inner surface of second recess 32. Wherein, brick main body 10, seat 20, first positioning block 21 and positioning strip 40 are integrally formed fixed connection structure, when producing, by mould pressing into brick blank, and the refractory brick structure described above is formed after firing of brick blank.
[0031] As the above structure, when carrying out straight wall masonry, two refractory bricks are combined and spliced, the first positioning block 21 on one of the brick main body 10 is inserted into the first recess 31 of the other brick main body 10, and the first positioning block 21 can be attached to the side wall of the first recess 31 and the side wall of the first positioning block 21 respectively. Based on the structure, two adjacent refractory bricks can be combined and positioned, to ensure that the orientation angle of the refractory bricks is consistent, so that the wall masonry is straight. Since the depth of the first recess 31 is less than the thickness of the first positioning block 21, a certain gap can be left between the end faces of the brick main body 10 for filling refractory mortar, so that the refractory mortar between the refractory bricks has a suitable thickness and good consistency, to ensure the masonry quality. When carrying out arc structure masonry, the positioning strip 40 is removed, so that the first positioning block 21 can rotate in the first recess 31, so that the two refractory bricks can be placed at a certain angle when combined and spliced. Since the first positioning block 21 abuts against the inner wall of the first recess 31, a certain gap can still be left between the end faces of the brick main body 10 for filling refractory mortar, the intervals between the brick main bodies 10 are consistent, so that the refractory mortar between the refractory bricks has a suitable thickness and good consistency, to ensure the masonry quality.
[0032] Wherein, since the positioning strip 40 is only fixedly connected with the inner side wall of the first groove 31 at its front end, and the upper and lower sides and the left and right sides of the positioning strip 40 are spaced apart from the inner surface of the groove, it is convenient to cut off the positioning strip 40 with a cutting machine or knock off the positioning strip 40 directly with a brick knife during on-site construction. The on-site processing of the refractory bricks is convenient, and can be used for accurate masonry of flat walls, and can also be used for masonry of arc structures after simple processing, and can ensure that the refractory bricks are filled with refractory mortar with appropriate thickness and good consistency. In addition, the protrusions and depressions of the brick body 10 are all arranged in the front-rear direction, and the molding of the end of the green brick does not need to provide a lateral core-pulling structure on the mold, so the structure of the mold can be simplified.
[0033] Specifically, in the embodiment, the first positioning block 21 includes a first positioning section 211 with a rectangular cross section and a second positioning section 212 with a semicircular cross section, the second positioning section 212 is located on the front side of the first positioning section 211, and the second positioning section 212 has the same width as the first positioning section 211, so that the side wall of the first positioning section 211 is tangent to the side wall of the second positioning section 212, and the depth of the first groove 31 is greater than the thickness of the second positioning section 212. The first groove 31 has straight side walls and arc side walls arranged in front and back, the straight side walls and the arc side walls are tangent, the depth of the gap 321 is D1, the depth of the first groove 31 is D2, the width of the straight side wall is D3, and the thickness of the first positioning block is D4, D3
[0034] As the above structure, when the refractory bricks are combined and spliced, part of the first positioning section 211 can be inserted into the first groove 31 and abut against the first positioning block 21, limiting the rotation between the refractory bricks, and ensuring the azimuth angle consistency when the refractory bricks are masonry flat walls. After the positioning strip 40 is removed, the first positioning block 21 can be rotated relative to the first groove 31 to adjust the angle between the refractory bricks, and when rotating, the axis of the second positioning section 212 is always collinear with the axis of the arc side wall, ensuring that the spacing of the brick body 10 is consistent when masonry arc structure.
[0035] In the embodiment, the upper end of the first groove 31 extends to the top surface of the brick body 10, so that the refractory bricks can be combined and spliced in an up-down moving manner, which is suitable for the case that the refractory bricks have insufficient transverse space when the edge is masonry.
[0036] In the embodiment, the height of the gap 321, the second groove 32 and the seat 20 is the same. Through this structure, when the first positioning block 21 rotates, the seat 20 can be rotated to extend into the second groove 32, which can increase the range of the placement angle between the refractory bricks, and also can limit the longitudinal movement between the refractory bricks, and increase the positioning effect.
[0037] In the embodiment, the second groove 32 extends to the side surface of the brick body 10 on the side opposite to the first groove 31. Through the structure, the refractory mortar can be supplemented during the masonry, and the mold forming of the green brick is facilitated.
[0038] In the above embodiment, the width of the positioning strip 40 is W, and 8≤W≤12mm, which ensures the strength and facilitates the removal.
[0039] With reference to Figures 6-7 Compared with the first embodiment, in the second embodiment, the positioning strip 40 is not arranged, the second positioning block 22 is arranged on the front side of the seat body 20, the front end of the second positioning block 22 has a third positioning section 221 with a semicircular cross section, and the third groove 33 is arranged at the rear end of the seat body 20, and the third groove 33 is matched with the third positioning section 221, that is, the cross section of the third groove 33 is semicircular.
[0040] When the straight wall is masonry, for the combination of two refractory bricks, the first positioning block 21 on one brick body 10 is inserted into the first groove 31 of the other brick body 10, and the third positioning section 221 is inserted into the third groove 33, so as to ensure the straight arrangement of the refractory bricks. When the arc structure is masonry, for the combination of two refractory bricks, the first positioning strip 40 is rotated relative to the first groove 31, at this time, the two refractory bricks have a certain angle, and the third positioning section 221 is separated from the third groove 33, through the abutting of the first positioning block 21 and the first groove 31, the spacing between the two refractory brick bodies 10 is consistent, and the consistency of the refractory mortar between the two refractory bricks is ensured.
[0041] In the embodiment, the upper end of the first groove 31 extends to the top surface of the brick body 10, so that the refractory bricks can be combined and spliced in the up-down moving mode.
[0042] In the embodiment, the positioning strip 40 is not arranged, and the refractory bricks can be directly used for the masonry of the arc structure, without the need for additional processing, so that the masonry of the refractory bricks is more convenient.
[0043] In addition, for the refractory bricks of the above embodiments, when the arc structure is masonry, there is generally a limiting piece or a mark line with an arc shape on the outside, and the refractory bricks are placed along the limiting piece / mark line, so as to ensure the accurate angle position of the refractory bricks, and the gap between the brick bodies 10 of the adjacent refractory bricks is controlled through the abutting of the first positioning block 21 and the inner wall of the first groove 31.
[0044] The embodiments of the utility model are described in detail above combined with the drawings, but the utility model is not limited to the above embodiments, and various changes can be made within the knowledge range of ordinary skilled persons in the technical field without departing from the purpose of the utility model.
