[0025] The present invention will be further illustrated below in conjunction with specific embodiments.
[0026] Example 1
[0027] The utility model relates to a slot-type light brick, the main body of which is a rectangular parallelepiped. The main body of the brick is cut to obtain bricks of two shapes.
[0028] Attached Figure 1 , 2As shown, a rectangular brick body 1 is cut and removed from a set of width edges on the lower surface to obtain a first brick having a set of concave right-angle steps 2 on the set of width edges on the lower surface.
[0029] Attached Figure 3 , 4 As shown, a rectangular brick body 1 is cut and removed from a set of width edges on the upper surface to obtain a second brick having a set of convex right-angle steps 3 on a set of width edges on the lower surface.
[0030] The maximum length, width and height of the first brick and the second brick are the same, that is, length A1 = A2, width B1 = B2, height C1 = C2. The width W of the inner concave right-angle step 2 and the outer convex right-angle step 3 are the same, W = 15-18 mm, and the height H is the same, H = 20-23 mm.
[0031] Attached Figure 5 As shown, the first bricks and the second bricks are laid alternately, the inner concave right-angle step 2 is engaged with the outer convex right-angle step 3, and the surfaces of the first bricks are flush with the second bricks.
[0032] It can be seen that the maximum length, width and height dimensions of the first brick and the second brick ensure that both are standard bricks, and can form a regular arrangement when paving. The sizes of the concave right-angle steps and the convex right-angle steps match. After being locked, the two bricks fit well together, and the upper and lower surfaces of the two bricks are flush. The ground reference requirements are the same before paving, and the road surface is flat after paving.
[0033] A method for manufacturing the above-mentioned slot-type lightweight brick comprises the following steps:
[0034] Raw material processing: sand and gypsum are sent to the ball mill through electromagnetic vibrating feeder and belt conveyor, and a certain amount of water is added to mix and grind. The ground slurry is pumped to the slurry tank for storage; lime and cement are sent to the powder storage bin for storage through screw conveyor and bucket elevator; aluminum powder is transported from the aluminum powder warehouse to the production workshop, lifted to the second floor of the batching building by electric hoist, poured into the mixer, and water is added in a certain amount to stir it into an aluminum powder suspension.
[0035] Batching, mixing and pouring of aerated blocks: the materials are sent to the automatic metering scale for cumulative metering in turn. There is a screw conveyor under the scale to evenly add the materials into the pouring mixer. If there is waste slurry, it can be added at this time and then stirred. The process requirements (about 40°C) should be met before pouring. If the temperature is not enough, steam can be used to heat the slurry metering tank. Aluminum powder suspension is added 0.5 to 1 minute before pouring the material, and then added to the mold for pouring.
[0036] Initial curing and cutting of aerated blocks: After pouring, the mold is pushed into the initial curing room by a conveyor chain for gasification and initial condensation. The room temperature is 50-70℃, and the initial curing time is 1.5-2 hours. After initial curing, the mold frame and the green body are hoisted together by a negative pressure hoist to the cutting table with the kettle bottom plate placed in advance. After removing the mold frame, the cutting machine cuts the green body to obtain an inner concave right-angle step or an outer convex right-angle step. After the mold frame is hoisted away, it is manually cleaned and degreased, and then hoisted to the mold car for the next pouring. The cut green body and the kettle bottom plate are hoisted to the kettle car by a crane and stacked in two layers. There are four supports between the layers, and several bottom machines are grouped together along the kettle car. The green body corner waste generated during cutting is sent to the waste slurry mixer next to the cutting machine through a screw conveyor, and water is added to make waste slurry for use when mixing.
[0037] Autoclave and finished products of aerated blocks: After the green bodies are assembled on the parking line in front of the autoclave, the aerated concrete is opened and the door of the autoclave to be taken out is first pulled out of the autoclave with a winch. Then the autoclave car to be autoclaved is pulled into the autoclave for curing with a winch. The finished product is taken out.
[0038] Example 2
[0039] It is basically the same as Example 1, except that Figure 6 , 7 As shown, the upper surface of the first brick is provided with a concave right-angle step 2 which is the same as that on the lower surface. Figure 8 , 9 As shown, the upper surface of the second brick is provided with a convex right-angle step 3 which is the same as that on the lower surface. Fig.10 As shown, the first bricks and the second bricks are laid alternately, and on the upper surface, the inner concave right-angle step 2 is engaged with the outer convex right-angle step 3, and on the lower surface, the inner concave right-angle step 2 is engaged with the outer convex right-angle step 3, and the surfaces of the first bricks and the second bricks are flush.
[0040] The slot-type lightweight bricks of the present application have splicing properties in structure. After alternate laying, the compressive strength can be measured to be A5.0 level, that is, the average value of the compressive strength is not less than 5MPa and the minimum value is not less than 4.2MPa. The stacking structure is stable and long-lasting, and the dry density can be B06 level, that is, the average dry density is not higher than 650kg / m 3 , sound insulation, fire prevention, light weight and good thermal insulation effect.
