Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, specifically a grooving tool for aerated concrete blocks. Background Technology
[0002] In authorized public building construction projects, aerated concrete blocks are widely used in the construction of non-load-bearing exterior walls, partition walls, and infill walls. The "Code for Construction of Masonry Structures" (GB50924-2014) requires that when autoclaved aerated concrete blocks are laid using the thin-layer mortar method, the connection between the blocks and tie bars should be achieved by pre-cutting grooves on the upper surface of the blocks at the corresponding positions. During construction, the reinforcement bars should be placed centered within the grooved mortar. The "Code for Acceptance of Construction Quality of Masonry Structures" (GB50203-2011) requires that for autoclaved aerated concrete block masonry constructed using the thin-layer mortar method, tie bars should be placed within grooves set on the upper surface of the blocks. Currently, the thin-layer mortar method is widely used in masonry construction, and the efficiency of groove cutting for tie bars directly affects the overall construction speed of the masonry.
[0003] While a variety of grooving tools for aerated concrete blocks are currently available on the market, they still have significant shortcomings in practical applications. Specifically, the size design of these tools often fails to accommodate various usage scenarios, greatly reducing their applicability. On the one hand, some grooving tools are bulky and heavy, making them extremely inconvenient for temporary or short-distance grooving, cumbersome to operate, and difficult to store and transport. On the other hand, while small tools are lightweight and portable, they struggle to ensure the depth and straightness of longer grooves, easily resulting in curved or uneven grooves, severely affecting construction quality and aesthetics. These limitations in size design make it difficult for existing grooving tools to meet diverse needs in practical applications, often requiring construction workers to select different tools for different grooving tasks, leading to poor applicability of grooving tools. Utility Model Content
[0004] The purpose of this utility model is to provide a grooving tool for aerated concrete blocks, which aims to solve the problem that existing grooving tools are difficult to meet diverse needs in practical applications, resulting in low applicability of grooving tools.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: the aerated concrete block grooving tool includes a clamping assembly clamped on the block wall, a mounting and dismantling housing provided on the clamping assembly, and a grooving component detachably connected to the mounting and dismantling housing.
[0006] The clamping assembly can be guided to move along the extension direction of the block wall;
[0007] The mounting and disassembly housing is sleeved on the clamping assembly, making the position of the mounting and disassembly housing relative to the clamping assembly adjustable in the left and right directions;
[0008] The mounting and disassembly housing includes two snap covers sleeved on the clamping assembly and arranged opposite each other, and two first nuts threadedly fitted on the clamping assembly with left and right intervals. The two snap covers are located between the two nuts. When the two first nuts are tightened, the two snap covers are engaged to form a clamping channel that is open from front to back and can clamp and fix the slotted part.
[0009] The slotting component is connected to the clamping assembly by installing and removing the housing, so that the slotting component moves along the extension direction of the block wall as the clamping assembly guides it to achieve slotting.
[0010] Preferably, the clamping assembly includes two clamping plates arranged opposite each other and extending in the front-back direction, two threaded rods arranged at a front-back interval and extending in the left-right direction that are detachably connected between the two clamping plates, and a second nut that is threadedly adapted to the threaded rods.
[0011] The clamping plate has two circular holes spaced apart front to back and open to the left and right, and the threaded rod is inserted into the circular holes;
[0012] The two ends of the threaded rod pass through round holes and are threaded to the second nut to clamp the two clamping plates on the left and right sides of the block wall.
[0013] Preferably, a hanging plate extending horizontally in the front-back direction is fixed on one side of the two clamping plates, and the hanging plate is perpendicular to the clamping plates.
[0014] When the clamping plate is held against the side wall of the block wall, the hanging plate can rest against the top of the block wall.
[0015] Preferably, each of the buckles has two through holes spaced apart front to back and open to the left and right, and the threaded rod is slidably inserted into the through holes of the buckle.
[0016] Each of the two buckles has a locking block and a locking groove fixed on its opposite side. When the two buckles are fastened together, the locking block can engage in the locking groove so that the two buckles are fixedly connected relative to each other.
[0017] Preferably, the slotted component includes a handle section, a plurality of protruding teeth fixed at one end of the handle section at intervals along the front-back direction, and a wrench component fixed at the other end of the handle section.
[0018] The handle section is placed into the clamping channel formed by the two snap-fit caps. The protruding teeth are set perpendicular to the block wall. Pushing the clamping assembly allows the protruding teeth to groove the block wall.
[0019] Preferably, a through hexagonal hole is fixed on the side of the handle section near the protruding teeth to allow the bolt to be tightened.
[0020] The beneficial effects are: 1. This device can be adjusted according to the grooving requirements. When grooving on a long block wall, it can be used in conjunction with the clamping components, the mounting and disassembling housing and the grooving parts. When used temporarily or when grooving on a short block wall, the operator can use the grooving parts by hand to groove, which improves the applicability of this device.
[0021] 2. When grooving long block walls, the clamping assembly can be securely held onto the block wall first. Next, the grooving component is accurately positioned and fixed within the mounting housing. As the clamping assembly moves, the grooving component will smoothly move along the block wall, achieving straight grooving. This design not only ensures the accuracy of the grooving process but also significantly reduces the operator's workload, making construction more efficient and convenient.
[0022] 3. After the slotting tool is removed from the mounting housing, the operator can easily hold it and perform slotting operations on shorter block walls. This design not only facilitates temporary use but also efficiently handles the slotting needs of shorter block walls, making the construction process more flexible and convenient. Whether for minor repairs or temporary construction, the handheld slotting tool provides operators with great convenience and flexibility. Attached Figure Description

[0028] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0029] In this embodiment, an aerated concrete block grooving tool is mainly used to groove the grooving part 3 on a longer block wall 4 by using the clamping component 1 and the installation and removal housing 2, or to groove the shorter block wall 4 by hand, so as to realize the adjustment according to the actual needs of the block wall 4 and improve the applicability of the grooving tool.
[0030] In this embodiment, the aerated concrete block grooving tool includes a clamping component 1 clamped on the block wall 4, a mounting and dismounting housing 2 provided on the clamping component 1, and a grooving component 3 detachably connected to the mounting and dismounting housing 2. The grooving component 3 can be installed on the clamping component 1 through the mounting and dismounting housing 2 so that when the clamping component 1 moves, the grooving component 3 can be moved along the extension direction of the block wall 4 through the mounting and dismounting housing 2, or the operator can hold the grooving component 3 to perform grooving.
[0031] like Figures 1-3 As shown, the slotted part 3 can be installed on the clamping assembly 1 by installing and removing the housing 2, or the slotted part 3 can be removed from the housing 2 and the slotting operation can be performed by hand.
[0032] Specifically, the mounting and disassembly housing 2 is sleeved on the clamping assembly 1, making the left and right position of the mounting and disassembly housing 2 relative to the clamping assembly 1 adjustable. The mounting and disassembly housing 2 includes two snap covers 201 sleeved on the clamping assembly 1 and arranged opposite to each other, and two first nuts 202 threadedly sleeved on the clamping assembly 1 with left and right intervals. The two snap covers 201 are located between the two nuts 202. When the two first nuts 202 move in opposite directions, the two snap covers 201 can be opened. Then, the slotted part 3 is placed between the two snap covers 201. Then, when the two first nuts 202 are tightened in opposite directions, the two snap covers 201 are engaged to form a clamping channel that is open from front to back and clamps and fixes the slotted part 3, so that the slotted part 3 is clamped and fixed in the clamping channel. This allows the slotted part 3 to be connected to the clamping assembly 1 through the mounting and disassembly housing 2, so that the slotted part 3 can be guided and moved along the extension direction of the block wall 4 by the clamping assembly 1 to achieve slotting.
[0033] Each cover 201 has two through holes spaced apart front to back and open to the left and right. The clamping component 1 is slidably inserted into the through holes of the cover 201. A locking block and a locking groove are fixed on opposite sides of the two covers 201 respectively. In this embodiment, the structure and principle of the locking block and the locking groove are existing technologies and will not be described in detail here. When the two covers 201 are fastened together, the locking block can be engaged in the locking groove so that the two covers 201 are relatively fixedly connected. Through the setting of the locking block and the locking groove, the two covers 201 can be more stable when connected.
[0034] like Figures 1-3 As shown, the clamping component 1 can clamp onto the block wall 4, so that the grooving component 3 can groove along the extension direction of the block wall 4 to ensure that the groove is straight.
[0035] Specifically, the clamping assembly 1 is guideable and movable along the extension direction of the block wall 4; the clamping assembly 1 includes two clamping plates 101 arranged opposite each other and extending in the front-back direction, two threaded rods 102 arranged spaced apart in the front-back direction and extending in the left-right direction detachably connected between the two clamping plates 101, and second nuts 103 threadedly adapted to the threaded rods 102. By rotating the two second nuts 103, the two clamping plates 101 are moved in opposite directions to clamp the two clamping plates 101. On the outer side of the block wall 4, the clamping plate 101 has two round holes that are spaced apart front and back and open to the left and right. The threaded rod 102 is inserted into the round holes. The two ends of the threaded rod 102 pass through the round holes and are threadedly connected to the second nut 103 to clamp the two clamping plates 101 on the left and right sides of the block wall 4. When the clamping plate 101 moves along the extension direction of the block wall 4, it can drive the slotting part 3 to move along the block wall 4 by installing and removing the housing 2, so that the long block wall 4 can be slotted.
[0036] A hanging plate 5 is fixed on one side of the two clamping plates 101, extending horizontally in the front-back direction. The hanging plate 5 and the clamping plates 101 are perpendicular to each other. When the clamping plates 101 are clamped and abutted against the side wall of the block wall 4, the hanging plate 5 can abut against the top of the block wall 4. The hanging plate 5 and the clamping plates 101 can play an auxiliary support role for the block wall 4.
[0037] like Figure 4 As shown, after the slotted part 3 is removed from the housing 2, the operator can manually slot it by holding the handle section 301.
[0038] Specifically, the slotting component 3 includes a handle section 301, several protruding teeth 302 fixed at one end of the handle section 301 at intervals along the front-back direction, and a wrench component 303 fixed at the other end of the handle section 301. The wrench component 303 enables the nut to be turned. The handle section 301 is placed into the clamping channel formed by the two snap covers 201. The protruding teeth 302 are set perpendicular to the block wall 4. Pushing the clamping component 1 enables the protruding teeth 302 to slot the block wall 4.
[0039] In this embodiment, the operator can also hold the handle section 301 and use the protruding teeth 302 to make grooves on the block wall 4.
[0040] A through hexagonal hole 6 is fixed on the side of the handle section 301 near the protruding tooth 302. The hexagonal hole 6 is fitted onto the corresponding nut so that the nut can be screwed on. In this embodiment, the hexagonal hole 6 is a nut of a conventional scaffolding coupler model.
[0041] Working principle: For a long block wall 4, the handle section 301 can be placed into the clamping channel formed by the two snap covers 201. The protrusion 302 is set perpendicular to the block wall 4. Then, by rotating the two second nuts 103, the two clamping plates 101 are moved in opposite directions to clamp the two clamping plates 101 on the outside of the block wall 4. Pushing the clamping assembly 1 allows the protrusion 302 to slot the block wall 4.
[0042] For shorter block walls 4, when the two first nuts 202 are moved in opposite directions, the two covers 201 are opened, and the slotted piece 3 located between the two covers 201 is taken out. Then the operator holds the handle section 301 and uses the teeth 302 to slot the block wall 4.
[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
