[0046] Embodiment 1

[0047] A grooving device applicable to masonry provided in this embodiment includes a planing base 1 and a planing cutter 2. Among them, the planing base 1 has a first surface 15, and the planing cutter 2 is installed on the planing base 1 and has a cutter head 21 protruding outward from the first surface 15.

[0048] The planing base 1 can also be called a planing head, and its overall shape can be a block; the first surface 15 is an outer side surface of the planing base 1. During operation, the planing base 1 can be placed on the masonry 4 [such as aerated block masonry], and the first surface 15 is in contact with the surface of the masonry 4; the first surface 15 is preferably a plane, so that the first surface 15 can closely adhere to the surface of the masonry 4 and slide relative to the surface of the masonry 4 under the action of a thrust force.

[0049] The planer tool 2 is installed on the planer base 1 and at least part of it protrudes from the first surface 15, and this protruding part can be called the tool head portion 21; when the first surface 15 abuts against the surface of the masonry body 4, the protruding tool head portion 21 can extend under the surface of the masonry body 4. At this time, by sliding the planer base 1 relative to the surface of the masonry body 4, a groove 41 can be planed out on the surface of the masonry body 4 by the tool head portion 21, and this groove 41 can be used to place the tie bars; the depth of the groove 41 is determined by the length that the tool head portion 21 extends out of the first surface 15, and the extending length of the tool head portion 21 is usually fixed during the planing process, so that the depth of the groove 41 can be kept consistent.

[0050] A grooving device applicable to masonry provided by the present utility model is provided with a planer base 1 and a planer tool 2, and the planer tool 2 has a tool head portion 21 protruding from the planer base 1. During operation, an operator can abut the first surface 15 of the planer base 1 against the surface of the masonry body 4 and push the planer base 1 to drive the planer tool 2 to move, so as to cut out a groove 41 on the masonry body 4 through the tool head portion 21 of the planer tool 2; compared with directly cutting using a blade, the present utility model can form the groove 41 in one-time through the tool head portion 21, with higher cutting efficiency, and can better control the depth of the groove 41, avoiding damage to the masonry body 4 caused by over-cutting or the groove 41 being unusable due to under-cutting.

[0051] During the above-mentioned planing process, the planer base 1 has the function of fixing the planer tool 2 and maintaining the accurate attitude of the tool head portion 21, and the masonry body 4 will also exert a resistance on the tool head portion 21 to hinder its movement. To overcome this resistance, on the one hand, the planer tool 2 itself needs to have a certain strength, and on the other hand, the connection between the planer tool 2 and the planer base 1 needs to have a certain strength. Therefore, preferably, the tool head portion 21 is arranged in the middle of the first surface 15, so that the planer base 1 can better fix the planer tool 2.

[0052] In one or several preferred embodiments, the width of the projection of the tool head portion 21 in the first direction decreases continuously or discontinuously in the direction away from the planer base 1.

[0053] The first direction can be the advancing direction of the planer base 1, and the advancing direction of the planer base 1 can also be called the planing direction; the present application also defines the width direction of the tool head portion 21, that is: the width direction of the tool head portion 21 is perpendicular to the first direction and parallel to the first surface 15.

[0054] The width of the projection of the tool head portion 21 in the first direction decreases continuously or discontinuously in the direction away from the planer base 1, that is, the upper part of the projection is wide and the lower part is narrow. When the planer base 1 moves in the first direction, a groove 41 with a wide upper part and a narrow lower part can be cut on the surface of the masonry body 4; it can be understood that the groove 41 cut by the tool head portion 21 also has the characteristic of a wide upper part and a narrow lower part. After the tie bars are placed, they can abut against the groove walls on both sides of the groove 41 at a certain depth position and be relatively stationary under the restraint of the groove walls, thereby reducing the dislocation of the tie bars caused by shaking and being beneficial to improving the project quality.

[0055] The edge of the projection of the cutter head 21 in the first direction can be a straight line, a curve, or a step. Preferably, the width of the projection of the cutter head 21 in the first direction decreases linearly in the direction away from the planing seat 1 until it decreases to zero; that is, the projection of the cutter head 21 in the first direction is an inverted triangle, and the cutter head 21 can cut a V-shaped groove on the masonry 4. The V-shaped groove has two planes at an angle, which can better clamp the tie rod.

[0056] In one or more preferred embodiments, a mounting groove 11 is provided on the planing seat 1, and the planing blade 2 partially extends into the mounting groove 11; and the length of the planing blade 2 protruding from the first surface 15 is adjustable.

[0057] The mounting groove 11 is used to mount the planer 2 . The planer 2 may include a mounting portion in addition to the cutter head 21 . The mounting portion may be fixed to the groove wall of the mounting groove 11 , thereby fixing the planer 2 .

[0058] The length of the planer 2 protruding from the first surface 15 is adjustable. When in use, the size of the planed groove 41 can be adjusted by changing the length of the planer 2 protruding from the first surface 15 to meet various planing needs. It can be understood that for the planer 2, the blade head 21 is the part that protrudes from the first surface 15, and its specific range varies according to the protruding length of the planer 2.

[0059] Preferably, the planer 2 includes a first planing flake and a second planing flake connected to each other, and the first planing flake and the second planing flake are inclined to each other to form a V-shaped groove facing the first direction.

[0060] The first flake and the second flake can be integrally formed or welded together. The first flake and the second flake are preferably sheet-like structures, such as blades. The V-shaped groove formed by splicing the first flake and the second flake faces the first direction, so that the two sides of the V-shaped groove opening, that is, the two sides of the cutter head 21 in the width direction protrude forward, and the two sides can be called cutting edges. When cutting, the cutting edges can be used as blades to first split the masonry 4, and then the blade of the cutter head 21 further separates the masonry 4. In this way, the planing resistance is greatly reduced, and a relatively regular groove 41 edge can be obtained.

[0061] In addition, the V-shaped groove can also be used for chip removal, and the waste chips from planing can be stored in the V-shaped groove and then discharged along the extension direction of the V-shaped groove. To this end, it is further preferred that the mounting groove 11 has a fixing surface 12 inside, the planer 2 is fixedly mounted on the fixing surface 12, and the V-shaped groove of the planer 2 is spaced from the side wall of the mounting groove 11.

[0062] By leaving a spacing space between the V-groove of the planer 2 and the side wall of the mounting groove 11, the waste chips collected by the V-groove can be discharged from the spacing space, preventing the waste chips from accumulating in the cut groove 41 to hinder the movement of the cutter head 21 or to expand and damage the groove 41.

[0063] In one or several preferred embodiments, a tool seat 22 is provided on the planer 2, and a fixed slide groove adapted to the tool seat 22 is provided in the mounting groove 11, and the tool seat 22 can move along the fixed slide groove to change the length of the planer 2 extending out of the first surface 15; it also includes a locking member 23, which can lock the tool seat 22 in the fixed slide groove.

[0064] A tool holder 22 can be set on the back of the planer 2 and slidably installed on the fixed slide groove. The sliding direction of the fixed slide groove allows the planer 2 to move toward or away from the first surface 15, thereby changing the length of the planer 2 extending from the first surface 15.

[0065] Preferably, the locking member 23 is a screw; a threaded hole can be set on the fixed slide groove, and a number of corresponding mounting holes can be set on the planer 2 and the tool holder 22, and the screw passes through the mounting hole and then engages with the threaded hole, thereby locking the tool holder 22 to the fixed slide groove; the number of mounting holes can be multiple along the sliding direction, so that screws can be passed through different mounting holes to form different lengths of the tool head 21.

[0066] Further preferably, the number of the threaded holes is two, and the tool holder 22 is fixed to the fixed slide groove by two screws to reduce the shaking of the planer 2 in the fixed slide groove.

[0067] In one or more preferred embodiments, the cutter head 21 is inclined toward the first direction.

[0068] The cutter head 21 is inclined toward the first direction, that is, the free end of the cutter head 21 extends toward the first direction. During operation, the free end can first split the masonry 4, thereby reducing the planing resistance; the cutting of the free end can also make the bottom of the groove 41 cut regularly.

[0069] In one or more preferred embodiments, the planing seat 1 has a first gripping portion 13 and a second gripping portion 14, and the first gripping portion 13 and the second gripping portion 14 are arranged on both sides of the first direction.

[0070] like Figure 1 As shown, the first gripping portion 13 and the second gripping portion 14 can be used by the operator to grip and push the planing seat 1 to move; the first gripping portion 13 and the second gripping portion 14 are not limited to extended handles, rollers, etc.; the first gripping portion 13 and the second gripping portion 14 are preferably symmetrically arranged.

[0071] Example 2

[0072] This embodiment provides a grooving device suitable for masonry, such as Figure 1-2As shown in the figure, it includes a planing base 1 and a planing tool 2, where: the planing base 1 is a rectangular block, the bottom surface of the planing base 1 is the first surface 15, and the planing base 1 is provided with a mounting groove 11 that penetrates from top to bottom and has a V-shaped cross-section, and the axis of the mounting groove 11 is inclined.

[0073] The planing tool 2 is fixedly installed in the mounting groove 11, and a part of the planing tool 2 extends out of the first surface 15; the planing tool 2 includes a connected first planing blade and a second planing blade, the first planing blade and the second planing blade are inclined to each other to form a V-shaped groove facing the first direction, the V-shaped groove is inclined upward, the first direction is parallel to the first surface 15, and the shape of the V-shaped groove matches that of the mounting groove 11; in the mounting groove 11, the inclined upper side of the planing tool 2 is spaced from the other side wall of the mounting groove 11.

[0074] Specifically, the lower parts of the first planing blade and the second planing blade are triangular, and the vertex of the triangle is located on the splicing line of the two, so that the projection of the lower part of the planing tool 2 in the first direction is an inverted triangle.

[0075] The planing base 1 is further provided with a cylindrical first holding part 13 and a second holding part 14, and the first holding part 13 and the second holding part 14 protrude from the planing base 1.

[0076] Embodiment 3

[0077] A grooving device applicable to masonry provided in this embodiment is different from that in Embodiment 1 or 2 in that the grooving device further includes a guiding mechanism, and the guiding mechanism includes a slider 36, a guiding plate 3 and a first clamping plate 32. The guiding plate 3 is fixedly connected to the first clamping plate 32. The guiding plate 3 is provided with a linear guide rail 31. The first clamping plate 32 has a first abutting surface 33 perpendicular to the guide rail 31, and the first abutting surface 33 is located on the lower side of the guiding plate 3; the slider 36 can move along the guide rail 31, and the planing base 1 is connected to the slider 36 through a connecting piece 37.

[0078] As Figure 3-4 shown in the figure, one end of the guiding plate 3 can be lapped on the first clamping plate 32 and fixedly connected to the first clamping plate 32. The guiding plate 3 has a guide rail 31 for the slider 36 to move. One side of the first clamping plate 32 close to the guide rail 31 is set as the first abutting surface 33; during operation, the guiding plate 3 can be lapped on the masonry 4 and the first clamping plate 32 is located outside the end of the masonry 4, so that the first abutting surface 33 abuts against the end face of the masonry 4, thereby determining the position of the guiding plate 3 through the first clamping plate 32; at this time, the operator can support the guiding plate 3 with one hand and push the planing base 1 to move with the other hand.

[0079] Since in most usage scenarios, a groove 41 perpendicular to its end face needs to be opened on the masonry 4, therefore, the first abutting surface 33 can be set perpendicular to the guide rail 31; if there are other usage needs, the first abutting surface 33 can also be inclined to a certain angle of the guide rail 31 according to the needs.

[0080] In one or several preferred embodiments, the guiding mechanism further includes a second clamping plate 34, which is detachably connected to the guiding plate 3. The second clamping plate 34 has a second abutting surface 35 perpendicular to the guide rail 31, and the second abutting surface 35 is opposite to and spaced from the first abutting surface 33.

[0081] The second clamping plate 34 can be arranged in a similar manner to the first clamping plate 32. The difference lies in that the second clamping plate 34 is detachably connected to the guiding plate 3, so that the distance between it and the first clamping plate 32 is adjustable; a second abutting surface 35 is provided on the second clamping plate 34, and the second abutting surface 35 is opposite to the first abutting surface 33. The masonry 4 can be placed between the first abutting surface 33 and the second abutting surface 35 and clamped by the two. At this time, the operator no longer needs to support the guiding plate 3.

[0082] Preferably, the second clamping plate 34 can slide along the guide rail 31 and has a locking mechanism to lock it at a certain position on the guide rail 31.
