[0002] Autoclaved aerated concrete board is a new type of green and environmentally friendly building material with light weight, porous material and different amount of anti-corrosion steel mesh added according to the structural requirements. It is produced by high temperature, high pressure and steam curing to produce autoclaved aerated concrete board with porous crystals. Its density is smaller than that of general cementitious materials, and it has excellent fire resistance, fire prevention, sound insulation, heat insulation, thermal insulation and other unparalleled properties.

[0003] In combination with the above content, it should be explained that during the production and cutting of traditional steam-pressurized concrete slabs, due to the continuous gas transportation and cutting requirements, the steam-pressurized concrete slabs are easily affected by the transportation and start-up cutting vibrations, resulting in positional deviation, which in turn causes the subsequent steam-pressurized concrete slabs to be misaligned and the cutting sections to be uneven;

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1: This embodiment is used to solve the problem that during the production and cutting of traditional steam-pressurized concrete slabs, due to the need for continuous gas transportation and cutting, the steam-pressurized concrete slabs are easily affected by the vibration of transportation and starting cutting, resulting in position deviation, which in turn causes the subsequent steam-pressurized concrete slabs to be misaligned and the cutting section is uneven.

[0026] See also Figure 1 - Figure 6As shown, this embodiment is a gas cutting unit for processing autoclaved aerated concrete panels with a positioning structure, including a conveying frame 1, a heightening frame 2 is arranged at the bottom of both sides of the conveying frame 1, support columns 101 are symmetrically arranged on both sides of the conveying frame 1, a pneumatic cutting frame 3 is arranged at one end of the support column 101, and a side limit frame 4 is arranged at the other end of the support column 101, a pneumatic cutting tool 303 is arranged at the bottom of the pneumatic cutting frame 3, and a grid 6 is arranged below the pneumatic cutting tool 303, and multiple groups of longitudinal clamping mechanisms 5 are arranged on the inner wall of the top of the conveying frame 1. When in use, the autoclaved aerated concrete panel is pulled by the conveying roller 106 to move along the top of the support plate 105 and close to the grid 6, and the conveying roller 106 stops operating after one end of the autoclaved aerated concrete panel exceeds the grid 6 by a fixed distance;

[0027] A support plate 105 is provided on the inner bottom wall of the conveying frame 1, and a plurality of conveying rollers 106 are symmetrically provided on the side of the support plate 105, a cutting groove 102 is provided at one end of the support column 101, and a limiting groove 103 is provided at the other end of the support column 101, and sliding grooves 104 close to the limiting grooves 103 are symmetrically provided on the inner walls on both sides of the conveying frame 1;

The external air pump connects the pneumatic cutting tool 303 and the air suction inclined frame 601 through a pipeline. The pneumatic cutting tool 303 starts cutting the surface of the autoclaved aerated concrete board, and the air suction inclined frame 601 continuously sucks the air around and above the grid 6, causing the broken particles and dust particles generated by the cutting to fall onto the grid 6, thereby reducing the interference above the cutting area, which helps the operator to clearly observe the cutting processing status.

The metal frame 501 contacts the top of the autoclaved aerated concrete board through the soft pad 502 until the autoclaved aerated concrete board is squeezed and locked on the conveying roller 106 from top to bottom;
