Abstract

The invention discloses a method for cutting an aerated concrete building blocks and a dinking machine thereof. The invention comprises the steps that: A. a line is drawn on the aerated concrete building blocks; B. the marked aerated concrete building blocks are put into a reaction frame; C. an upper cutting point is put on the aerated concrete building blocks in the reaction frame; D. a jack is put on the cut; E. the jack is started to ensure that a piston for jack tightly goes against a reaction beam on the upper part of the reaction frame; F. the jack is started and the aerated concrete building blocks are sheared off; the reaction frame of the dinking machine is formed by welding two pieces of angle iron sheets with isosceles trapezoid by a connection reinforcing steel bar; the middle of the bottom of the reaction frame is welded with a lower cutting point armor plate stiffening rib welded with an lower cutting point armor plate; the steel insides of the upper base angle and the lower base angle of the angle iron sheets with the isosceles trapezoid of the reaction frame are respectively welded with two pairs of lead rails which slide on the upper cutting point; the armor plates of the upper cutting point are respectively sealed with an upper cutting point angle iron and two pairs of ear throughs which face the same direction. The method of the invention has the advantages of easy implementation, convenient usage, simple structure and light dead weight, and convenient move on site of the construction.

Description

technical field

[0001] The invention relates to the technical field of building construction machinery, more specifically to a method for cutting an aerated concrete block, and also to a cutting machine for an aerated concrete block. Background technique

[0002] Due to the advantages of light weight and porous insulation, aerated concrete blocks are currently widely used in filling walls of buildings. However, the length of filling walls is generally not an integer multiple of the size of aerated concrete blocks, and at the same time must meet the inability of masonry. There are code requirements for the existence of through joints, and the aerated concrete blocks need to be cut according to the size required for the infill wall.

[0003] At present, the steel plate saw is often used to saw off the aerated concrete block along the pre-marked cutting line at the construction site. Although it is neat and uniform, the work efficiency is low, and the steel plate saw is easy to...

Examples

Embodiment Construction

[0030] A method for cutting an air-entrained concrete block, the steps of which are:

[0031] 1. Draw (mark) a line on the aerated concrete block to be processed according to the required size as a cutting mark.

[0032] 2. Put the marked aerated concrete block into the reaction frame, so that the marking line on one side of the aerated concrete block is aligned with the lower edge of the knife.

[0033] 3. Then put the upper knife edge on the aerated concrete block in the reaction frame, make the ear groove of the upper knife edge fit into the guide rail on the reaction force frame, and align the knife edge with the marking line.

[0034] 4. Put a thin jack on the upper edge of the knife. According to the thickness of the processed aerated concrete block, use wooden boards of different thicknesses to adjust the gap between the upper part of the jack and the upper reaction beam of the reaction frame so that it is not greater than the stroke of the jack. 1 / 3, and make the jack...
