Cutting machine for tie-bar groove in aerated concrete block wall

Abstract

The invention provides a cutter of a steel tie bar groove of an aerated concrete block wall and belongs to a cutter. The cutter is characterized in that the cutter mainly comprises a rack, a motor, a belt transmission pair, circular steel gear pieces, a spindle, bearing supports, a block fixing bracket, tracks and a power switch case. The rack is formed mainly by assembling and welding landing legs, a bottom longitudinal beam, a bottom cross beam, a top longitudinal beam, a top cross beam and platform boards. The tracks are mounted on the front platform board and the rear platform board. The spindle is mounted at the middle sections of a front lower cross beam and a rear lower cross beam of the rack. The circular steel gear pieces are mounted at the middle section of the spindle in a sleeving manner at an interval front and rear, and are correspondingly positioned in a through space between the front platform board and the rear platform board. The motor and the belt transmission pair are mounted on the rack to drive the circular steel gear pieces. The block fixing bracket is mounted on the front track and the rear track in a sliding manner. Pressing boards and screwdown threaded rods are also mounted on the tracks. An aerated concrete block is mounted in the block fixing bracket and pushed and pulled back and forth, so that the aerated concrete block can be cut quickly and precisely. The efficiency is high, and the cost is low.

Description

technical field [0001] The invention belongs to a cutting machine, in particular to a cutting machine for aerated concrete block reinforcement grooves. Background technique [0002] Cracks in walls have always been a difficult problem to overcome in construction engineering. For preventing cracks in walls, the general measures to take are: set up long tie (joint) steel bars in the wall. At present, in construction projects, a large number of aerated concrete blocks are used for the masonry of the infill walls of the frame and shear wall structures, and the connection between the aerated concrete blocks and the frame structure is mainly connected by L-shaped angle iron pieces, but this L Shaped iron parts cannot penetrate along the wall, so the tie (connection) force between the wall and the frame column is small, and it is difficult to control the appearance of cracks in the wall; and if the tie (connection) force used in traditional brick wall masonry is used connection) s...

Problems solved by technology

At present, in construction projects, a large number of aerated concrete blocks are used for the masonry of the infill walls of the frame and shear wall structures, and the connection between the aerated concrete blocks and the frame structure is mainly connected by L-shaped angle iron pieces, but this L Shaped iron parts cannot penetrate along the wall, so the tie (connection) force between the wall and the frame column is small, and it is difficult to control the appearance of cracks in the wall; and if the tie (connection) force used in traditional brick wall masonry is used connection) steel bars, and because the thickness of the mortar joints used in the aerated concrete blocks is small, it is impossible to directly bury the tie (joint) steel bars; The diameter specification slots to bury tie (joint) steel bars in this slot

For grooving, currently the only tool available on the market is a hand-held small cutting machine, but this kind of cutting machine cannot cut grooving accurately, not only the lines of the cut notch are not straight, the depth of the notch is different, and the blocks are cut out. The notches of the joints are inconsistent, resulting in the failure of the tie (joint) steel bars to be buried smoothly, and the work efficiency is low, which cannot meet the construction requirements
