Description

Technical Field

[0001] This utility model relates to the field of masonry construction, specifically to a simple tool for grooving aerated concrete blocks. Background Technology

[0002] According to design drawings or specifications, the spacing should typically be ≤600mm, and at least one 6mm diameter rebar should be installed for every 120mm of wall thickness, as required by GB50203, "Code for Acceptance of Construction Quality of Masonry Structures". Common on-site practice involves directly placing the wall tie bars on the aerated concrete block or having workers use short rebar ends to draw lines and grooves on the block surface, making it difficult to control the grooving quality. Furthermore, the inconvenience of operation leads to significant labor intensity. A utility model with publication number CN217752110U provides a grooving tool for aerated concrete blocks. To facilitate the replacement of the grooving knife and positioning plate, a bolt-fixing method is further disclosed. However, in this method, bolt installation and removal are inconvenient, and moving parts are easily damaged. Utility Model Content

[0003] To address the shortcomings of current grooving tools for slotting aerated concrete blocks, such as inconvenience in use, this utility model provides a simple tool for slotting aerated concrete blocks.

[0004] A simple tool for slotting aerated concrete blocks includes a handle, mounting components, a slotting component, and a positioning component. Two mounting components are symmetrically arranged on two parallel sides of the same end of the handle, and the slotting component and the positioning component are respectively mounted thereon.

[0018] The following components are labeled in the diagram: handle 1, mounting component 2, nut 21, bearing plate 22, buffer plate 23, slotted part 3, slotted part mounting part 31, cutting part 32, positioning part 4, positioning part mounting part 41, contact part 42, baffle 43. Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1: Please also refer to Figure 1 and Figure 2 These are, respectively, a structural schematic diagram of the simple tool for slotting aerated concrete blocks provided by this utility model, and an exploded structural schematic diagram.

[0021] The simple tool for slotting aerated concrete blocks includes a handle 1, an installation component 2, a slotting component 3, and a positioning component 4.

[0022] The handle 1 is a square steel tube with one end covered with rubber (not shown in the attached figure) for easy gripping, and the other end has a mounting component 2 on each of the two opposite sides along the upper edge.

[0023] Mounting assembly 2 includes a nut 21 and a support plate 22. The support plate 22 is a long, rectangular steel plate arranged along the upper edges of opposite sides of the end of the handle 1 and welded to the handle 1. Three through holes are evenly spaced along the length of the support plate 22. The diameter of the through holes in the support plate 22 is larger than the circumscribed circle diameter of the nut 21. A nut 21 is placed at each of the three through holes in the support plate 22, and the nut 21 is also welded to the handle 1.

[0024] Furthermore, multiple rubber pads are attached to the support plate 22 as buffer plates 23. The buffer plates 23 are sandwiched between the slotted part 3 and the support plate 22, and between the positioning part 4 and the support plate 22, playing a role in buffering and shock absorption, and improving the comfort of using the tool.

[0025] Because the buffer plate 23 is prone to wear, it is installed using an adhesive method to facilitate replacement. This also allows for easy adjustment of the thickness to suit the user's operating habits.

[0026] The thickness of the bearing plate 22 is slightly greater than the thickness of the nut 21, thus creating a small height difference between them. This ensures that the slotted part 3 or the positioning part 4 will not come into contact with the nut 21 without the buffer plate 23, thereby ensuring the flatness and stability of the contact surface.

[0027] The slotted component 3 includes a slotted component mounting part 31 and a cutting part 32, which are integrated into one unit. The cutting part 32 is a semi-circular saw blade, widened on its flat side to form the slotted component mounting part 31. Three through holes are provided along the slotted component mounting part 31, corresponding to the positions of the three nuts 21 in the mounting assembly 2. By passing the fixing bolts sequentially through the washer and the through holes of the slotted component 3, and screwing them into the nuts 21, the slotted component 3 is fixed.

[0028] The positioning component 4 includes a positioning component mounting part 41 and a contact part 42. The two parts are parallel to each other and staggered. The overall length is equal to the length of the slotted component 3, and the width (i.e., the height of the view in the figure) is greater than the width of the slotted component 3. Three through holes are provided along the positioning component mounting part 41, and their positions correspond to the positions of the three nuts 21 in the mounting assembly 2. By passing the fixing bolts through the washer and the through holes of the positioning component 4 in sequence, and screwing them into the nuts 21, the slotted component 3 is fixed.

[0029] Furthermore, the through holes of the slotted part 3 and the positioning part 4 abut against the fixing bolts, which laterally limit the slotted part 3 and the positioning part 4, making the installation of the slotted part 3 and the positioning part 4 more stable.

[0030] The handle 1 also has through holes (not shown in the attached figure) at the positions of each nut 21, for the fixing bolts to pass through, so that it can accommodate bolts of various lengths.

[0031] In use, hold the rubber-coated end of the handle 1 with the slotted part 3 and the positioning part 4 facing downwards, and the inner side of the positioning part 4 abutting against the side wall of the aerated concrete block. Starting from the end of the aerated concrete block, apply pressure with one hand and pull with the other to carve a straight groove on the top of the aerated concrete block. By replacing different positioning parts 4, multiple parallel grooves can be carved on the aerated concrete block.

[0032] Example 2: Please refer to Figure 3 This is a structural schematic diagram of the simple tool for slotting aerated concrete blocks provided by this utility model. The difference from Embodiment 1 is:

[0033] The positioning component 4 includes a positioning component mounting part 41 and a contact part 42, which are parallel to each other and staggered. The overall length is equal to the length of the slotted component 3, and the width (i.e., the height from the perspective shown in the figure) is greater than the width of the slotted component 3. A baffle 43 is vertically provided on the inner side of the contact part 42, and the height of the baffle 43 is less than the height of the slotted component 3.

[0034] When in use, hold the rubber-coated end of the handle 1 with the slotted part 3 and the positioning part 4 facing downwards. The contact part 42 and the baffle 43 in the positioning part 4 abut against the side wall and top of the air block, respectively, thereby positioning from both the width and height directions, and simultaneously defining the position and depth of the slot.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
