Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building block technology and relates to a grooved device for tie bars of adjustable width aerated concrete blocks. Background Technology
[0002] Tie bars are primarily used to resist tensile forces in concrete structures, increasing the structure's tensile load-bearing capacity. Concrete is relatively fragile under stress, but the addition of tie bars significantly enhances the structure's tensile strength. The use of tie bars improves the ductility of the concrete structure, making it more resilient and deformable under external loads, thus better adapting to changes in the structure's stress state. Furthermore, tie bars can slow down the cracking rate of concrete, improving crack resistance. The slotted design of the tie bars ensures a stronger connection between the tie bar and the concrete, thereby improving the structure's load-bearing capacity and seismic performance.
[0003] Chinese patent CN222223103U discloses an adjustable-width aerated concrete block tie bar grooving device: an anti-slip handle is vertically fixed to an intermediate sleeve by welding, an assist handle is welded to the top of the intermediate sleeve, the assist handle is inclined towards the anti-slip handle, an adjusting beam one is assembled on the left side of the intermediate sleeve, and an adjusting beam two is assembled on the right side of the intermediate sleeve. The adjusting beam one, the adjusting beam two, and the intermediate sleeve constitute an adjustable-width beam, a limiting card one is welded vertically downward on the side of the adjusting beam one, a grooving tool one is welded vertically downward on the middle position of the adjusting beam one, a limiting card two is welded vertically downward on the side of the adjusting beam two, and a grooving tool two is welded vertically downward on the middle position of the adjusting beam two.
[0004] The existing adjustable width aerated concrete block tie bar grooving device has the following problems: since the fixed limit card and the grooving tool are welded to the adjusting beam, the fixed limit card and the grooving tool cannot be replaced once they are deformed. Moreover, the fixed limit card is too large in width to be used for grooving non-linear bricks such as arcs. Utility Model Content
[0005] To address the aforementioned problems in the existing technology, this application provides an adjustable-width aerated concrete block tie bar slotting device.
[0006] The technical solution of this utility model is as follows:
[0007] A grooving device for adjustable-width aerated concrete block tie bars includes an angle steel body connected with an anti-slip handle. The right side of the angle steel body is provided with a limiting steel bar 1 and a grooving tool 1, the length of the limiting steel bar 1 being greater than the length of the grooving tool 1. The left side of the angle steel body is provided with a limiting steel bar 2 and a grooving tool 2, the length of the limiting steel bar 2 being greater than the length of the grooving tool 2. An elongated slot is opened on the upper surface of the angle steel body. Fasteners pass through the elongated slot to fix the limiting steel bar 1, the grooving tool 1, the limiting steel bar 2, and the grooving tool 2 to the angle steel body.
[0008] As a preferred embodiment of the present invention: the fastener includes fixing bolt one, fixing bolt two, fixing bolt three and fixing bolt four. Fixing bolt one is assembled on the top of limiting steel bar one, fixing bolt two is assembled on the top of grooving tool one, fixing bolt three is assembled on the top of grooving tool two, and fixing bolt four is assembled on the top of limiting steel bar two.
[0009] In a preferred embodiment of this utility model, the top of the angle steel body is connected to the power handle via a hinge device.
[0010] As a preferred embodiment of this utility model: the anti-slip handle is bent and engraved with anti-slip texture.
[0011] As a preferred embodiment of this utility model: a closed end plate 1 is connected to the right end of the angle steel body, and a closed end plate 2 is connected to the left end of the angle steel body.
[0012] The beneficial effects of this utility model are:
[0013] This utility model discloses an adjustable-width aerated concrete block tie bar grooving device. Because fasteners pass through long slots to fix the first limiting rebar, the first grooving tool, the second limiting rebar, and the second grooving tool to the angle steel body, the position of the grooving tool and the limiting rebar can be flexibly adjusted after loosening the fasteners, thus flexibly adapting to aerated concrete blocks of various thicknesses. If the fixing limiting card and the grooving tool are deformed, the fasteners can be loosened for quick replacement. The first and second limiting rebars on both sides of the angle steel body have reduced width dimensions, which can be applied to grooving of non-linear bricks such as arcs, thus improving applicability.

Detailed Implementation
[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0017] like Figure 1 As shown, an adjustable-width aerated concrete block tie bar grooving device includes an angle steel body 1 connected with an anti-slip handle 2. The right side of the angle steel body 1 is provided with a limiting steel bar 4 and a grooving tool 3, the length of the limiting steel bar 4 being greater than the length of the grooving tool 3. The left side of the angle steel body 1 is provided with a limiting steel bar 2 14 and a grooving tool 2 15, the length of the limiting steel bar 2 14 being greater than the length of the grooving tool 2 15. The upper surface of the angle steel body 1 is provided with a long slot 8. Fasteners pass through the long slot 8 to fix the limiting steel bar 4, the grooving tool 3, the limiting steel bar 2 14, and the grooving tool 2 15 to the angle steel body 1.
[0018] The fasteners include fixing bolt 6, fixing bolt 7, fixing bolt 11, and fixing bolt 12. Fixing bolt 6 is mounted on the top of the limiting reinforcing bar 4, fixing bolt 7 is mounted on the top of the grooving tool 3, fixing bolt 11 is mounted on the top of the grooving tool 2 15, and fixing bolt 12 is mounted on the top of the limiting reinforcing bar 2 14.
[0019] The top of the angle steel body 1 is connected to the power handle 9 via a hinge device 10, which allows the operator to flexibly control the direction of the power handle and make it easier to exert force; the anti-slip handle 1 is bent and engraved with anti-slip texture, which can improve grip stability; the right end of the angle steel body 1 is connected to a closed end plate 1 5, and the left end of the angle steel body 1 is connected to a closed end plate 2 13.
[0020] When operating the device, the operator first adjusts the positions of the limiting steel bar 14, the grooving tool 13, the limiting steel bar 24, and the grooving tool 25 according to the width of the aerated concrete block. Then, the device is placed on the aerated concrete block to be grooved. The limiting steel bars 14 and 24 on both sides clamp the sides of the aerated concrete block to control the grooving direction. One hand holds the anti-slip handle 1 and moves back and forth along the direction of the aerated concrete block, while the other hand holds the assist handle 9 to cooperate in the force. The grooving work of two tie bar grooves can be completed in one operation. Once the fixing limiting card and the grooving tool are deformed, the fixing bolts 16, 27, 31, and 41 can be loosened for quick replacement.
