The lower half part of the cover slit brick 4 is embedded into the large brick layer 3 at the bottom of the pool, and the ramming layers are embedded into the upper part of the cover slit brick to the two sides, so that the cover slit brick 4 is in a stable structure, and the effect of separating glass liquid from the ramming material layer 2 of the cover slit brick 4 can be fully exerted.
As shown in fig. 1, the cover seam brick 4 can completely isolate the expansion seam between the ramming material layer 2 and the large brick layer 3 at the bottom of the pool, and as ramming materials are bulk materials made of various materials and easily fall into the expansion seam of the large brick layer 3 at the bottom of the pool, the risk that the free expansion of the bottom of the pool is affected by the ramming material layer 2 falling into the brick seam is avoided through the blocking of the cover seam brick 4; meanwhile, as the width of the upper end of the cover seam brick 4 is large, even if construction errors or expansion displacement exist, the position deviation of the expansion seam of the upper layer pavement beyond the cover seam brick 4 can be avoided, and the erosion of the ramming material layer 2 by glass liquid is avoided, so that the quality defects and potential safety hazards are eliminated.
The cross section of the joint brick 4 is of a T-shaped structure. The joint brick 4 is designed into a T shape, the material is the same as that of the paving brick layer 1, and the fused zirconia corundum brick is also selected. The T-shaped structure can strengthen the structural strength of the joint brick 4, and when the refractory material expands during the baking of the glass melting furnace, the brick bulge caused by expansion can be avoided.
The upper end of the large brick layer 3 at the bottom of the pool is provided with a mounting groove 5, the lower part of the joint brick 4 is arranged in the mounting groove 5, and the upper end of the joint brick 4 is arranged in the ramming mass layer 2. The mounting groove 5 can be used for mounting the lower structure of the cover slit brick 4, the lower part of the cover slit brick 4 is partially embedded into the large brick layer 3 at the bottom of the pool, the grooving width dimension of the large brick layer 3 at the bottom of the pool is larger than the width of the lower part of the cover slit brick 4, the depth of the cover slit brick 4 embedded into the large brick layer 3 at the bottom of the pool is equal to the grooving depth of the large brick layer 3 at the bottom of the pool, and the depth is generally 40-100 mm according to production requirements.
As shown in fig. 1, a gap 6 is arranged between two sides of the lower part of the joint brick 4 and the side end of the mounting groove 5. The gap 6 is used as an expansion joint of the large brick layer 3 at the position of the mounting groove 5, the gap 6 can be used for buffering expansion displacement generated when the brick body is heated, and the width of the gap 6 is larger than half of the expansion joint 7 of the large brick layer 3 at the bottom of the pool.
The ramming mass layer 2 presses the side ends of the cover-joint bricks 4, and the paving brick layer 1 and the large brick layer 3 at the bottom of the pool respectively press the upper end and the lower end of the cover-joint bricks 4. The upper end of the cover slit brick 4 is embedded into the ramming mass layer 2, the lower end of the cover slit brick is arranged in the mounting groove 5, the paving brick layer 1, the large pool bottom brick layer 3 and the ramming mass layer 2 compress tightly the cover slit brick 4, so that the cover slit brick 4 forms a stable mounting structure, and the isolation effect of the cover slit brick 4 is further enhanced.
As shown in fig. 1, the thickness of the upper end of the cover slit brick 4 is matched with the thickness of the ramming mass layer 2, and the thickness of the lower end of the cover slit brick 4 is matched with the depth of the mounting groove 5.
