Description

Technical Field

[0001] This application relates to the field of building construction, specifically to a cutting control device for autoclaved aerated concrete blocks. Background Technology

[0002] With the acceleration of industrialization in the construction industry and the continuous upgrading of engineering quality control standards, aerated concrete masonry, as the core material for non-load-bearing interior partition walls in prefabricated buildings, directly affects structural stability and construction acceptance rates due to its masonry forming accuracy. For the cutting of aerated concrete blocks in irregularly shaped structural parts such as non-right-angle corner walls, existing technologies have significant drawbacks: traditional handheld cutting devices rely on operator experience for angle adjustment, resulting in angle deviation rates as high as ±5° or more and cut surface flatness exceeding tolerance by ≥3mm. This leads to a reduced block suitability rate, increased material loss due to secondary finishing operations, and the generation of large amounts of construction solid waste, severely hindering the achievement of green construction goals. Utility Model Content

The cutting table includes a table body and cutting blades disposed on the table body. The control device includes a push-pull table body disposed on the table body and a block angle controller disposed on the push-pull table body. The block angle controller includes a main support beam laid flat on the push-pull table body and perpendicular to the cutting blades, and an L-shaped block support hinged to the main support beam at a right angle. The L-shaped block support includes a long side plate support and an end side plate support that are perpendicular to each other. The slot of the L-shaped block support faces the cutting blades. An adjustable auxiliary support rod is provided between the middle of the long side plate support and the main support beam. The long side plate support is also provided with an arc ruler for measuring the angle between the long side plate support and the main support beam. One end of the adjustable auxiliary support rod is hinged to the long side plate support, and the other end is fixed at different positions on the main support beam to achieve multi-angle support in the long side plate support.

[0005] Furthermore, the main support beam is provided with an arc indicator plate.

[0006] Furthermore, the push-pull tabletop includes a plate and a cutting slit disposed within the plate, with cutting blades extending upward from the cutting slit.

[0008] Furthermore, the cutting seam is set along the length of the push-pull table surface and perpendicular to the main support beam.

[0009] Furthermore, the push-pull table surface is provided with a support plate for positioning the main support beam.

[0010] Furthermore, the top surface and / or side surface of the table body are provided with limiting grooves, and the push-pull table surface is provided with guide rods.

[0018] Example 1 A control device for cutting autoclaved aerated concrete blocks, such as Figure 1 and 2 As shown, the cutting table is placed on the cutting table, which includes a table body and a cutting blade 1 on the table body. The control device includes a sliding table 2 on the table body and a block angle controller 3 on the sliding table 2. The block angle controller 3 includes a main support beam 31 that is laid flat on the sliding table 2 and is perpendicular to the cutting blade 1, and an L-shaped block support 32 that is hinged to the main support beam 31 at a right angle. The L-shaped block support 32 includes a long side plate support and an end plate support that are perpendicular to each other. The slot of the L-shaped block support 32 faces the cutting blade 1. An adjustable auxiliary support rod 33 is provided between the middle of the long side plate support and the main support beam 31. The long side plate support is also provided with an arc ruler 34 for measuring the angle between the long side plate support and the main support beam 31. One end of the adjustable auxiliary support rod 33 is hinged to the long side plate support, and the other end is fixed at different positions on the main support beam 31 to achieve multi-angle support in the long side plate support. The main support beam 31 is made of square steel tube, and the square steel tube is provided with a strip-shaped through hole 36. The end of the adjustable auxiliary support rod 33 is fixed to the strip-shaped through hole by a wing nut 37.

[0019] The main support beam 31 is provided with an arc indicator plate 35. The push-pull table 2 includes a plate 21 and a cutting slit 22 provided in the plate 21. The cutting blade 1 protrudes upward from the cutting slit 22. The push-pull table 2 includes two stainless steel plates arranged at a certain distance. The gap between the two stainless steel plates is the cutting slit 22. The two stainless steel plates are connected by a protective cover 24. The cutting slit 22 is arranged along the length of the push-pull table 2 and perpendicular to the main support beam 31. The push-pull table 2 is provided with a support plate 23 for positioning the main support beam 31. The top surface and / or side surface of the table body is provided with a limiting groove. The push-pull table 2 is provided with a guide rod. The end of the guide rod is limited in the limiting groove and moves back and forth in a straight line along the limiting groove. The adjustable auxiliary support rod 33 is made of iron sheet.

[0020] Protective cover 24 is mainly used to connect the stainless steel plates on both sides, and mainly includes two models: One type is an inverted U-shaped structure, in which the two side plates of the inverted U-shaped structure are bolted to the two stainless steel plates on both sides and fixed on the side away from the operator; A device includes two side plates and an arc-shaped plate connecting the two side plates, with the arc-shaped plate facing the cutting blade for operator protection.

[0021] Method for cutting blocks using this device: S1 Adjusting the Designated Angle: By loosening the adjustable auxiliary support rod, according to the cutting angle requirements, the sliding motion of the adjustable auxiliary support rod in the strip-shaped through hole drives the arc ruler to rotate, and the reading pointer indicates the design angle on the arc indicator plate 35; the main support beam 31 is made of square steel tube, and the square steel tube has a strip-shaped through hole, and the end of the adjustable auxiliary support rod 33 is fixed to the strip-shaped through hole by the wing nut 37; S2 Angle Fixing: When the angle indicated by the arc indicator on the arc ruler line is consistent with the design angle, rotate the wing nut to fix the adjustable auxiliary support rod to achieve angle fixing; S3 straightedge marking: Mark lines by placing aerated blocks on L-shaped block supports and marking lines according to the ruler.

[0022] S4 Cutting: Push the handle 5 to push the push-pull table 2 forward. Pushing and pulling the table 2 drives the block angle controller 3 through the support plate, which in turn drives the block 4 to move forward. The cutting blade cuts according to the scribing line to obtain the aerated concrete block with the required angle. The cutting process can be assisted by manually pressing the block.

[0023] Example 2 The block angle controller 3 is a modular angle steel structure frame, specifically consisting of a main support (Q235B), a slide rail adjustable angle frame (adjustable auxiliary support rod), and a high-precision angle calibration mechanism. The radian ruler (graduation value 0.5°) is hinged to the frame by stainless steel rivets to form a continuously adjustable measurement reference surface from 0° to 90°. The dynamic locking system adopts a slide rail-ratchet interlocking mechanism, which realizes continuous adjustment and rapid positioning of the cutting angle through a wing nut.

[0024] A 50*50*5 square steel beam, pre-drilled and slotted, serves as the base frame support beam 1 of the device. A 50*4 angle steel beam serves as a rotatable scale. The two are connected by a wing nut and a rotating shaft 3 bolt to form the support system of the device. A riveted arc ruler is installed on the scale as the device's protractor. An iron plate, riveted and fixed at the bottom of the base frame support beam adjacent to the protractor, serves as the reading pointer. The two together form the angle measurement system of the device. An iron plate is used as a locking plate. One end of the iron plate is bolted to the corner frame support beam with a wing nut, and the other end is bolted to the pre-slotted grooved corner frame of the square steel base frame support beam. The two together form the corner frame locking system of the device.
