Description

Technical Field

[0001] The utility model relates to the technical field of building wall construction, and particularly to a grooving tool applicable to ALC wall panels. Background Technique

[0002] ALC wall panels, also known as ALC (Autoclaved Lightweight Concrete) autoclaved aerated concrete wall panels, are a new type of building material produced using raw materials such as cement, sand, coal ash, gypsum, and lightweight aggregates. They have characteristics and advantages such as light weight, fire resistance, sound insulation, environmental friendliness, economy, and convenient construction. They have good heat insulation and sound absorption performance. Raw materials such as cement, sand, water, and coal ash are all treated under high temperature and high pressure, so that the ALC wall panels have certain fire resistance.

[0003] At present, new buildings in most cities are constructed using aluminum formwork, ALC wall panels, and indoor plaster-free processes. In order to enhance the connection between ALC wall panels and the main structure and reduce the risk of joint cracking between ALC wall panels and the main structure, reinforcement fittings are usually set at the ALC-concrete interface for connection. Since there is no indoor plastering, the reinforcement fittings are higher than the ALC wall surface, which is not conducive to later-stage fine decoration.

[0004] In view of the above deficiencies, we need to develop a grooving tool applicable to ALC wall panels to meet the usage requirements of the majority of users. Content of the Utility Model

[0005] In view of the problem that the existing ALC wall surface has reinforcement fittings higher than the ALC wall surface due to indoor plaster-free, which is not conducive to later-stage fine decoration, the technical solution adopted by the utility model to solve its technical problems is:

[0006] A grooving tool applicable to ALC wall panels, comprising a base assembly and a cutter assembly. The base assembly includes a base frame and a base limit member that are convenient to fit on the ALC wall panel. The cutter assembly includes a handle member and a cutter member fixedly connected to the handle member. The base limit member is fixedly connected to the side of the base frame away from the handle member. The handle member slides along the length direction of the base frame on the base frame and drives the cutter member to perform grooving processing on the ALC wall panel.

[0007] Further, a grooving stroke cavity that penetrates up and down is provided in the middle of the base frame, and the handle member moves in the grooving stroke cavity to limit the grooving range of the cutter member.

[0008] Further, the cutter assembly includes a grooving limit member for limiting the grooving direction. The grooving limit member is located between the handle member and the cutter member and is located in the grooving stroke cavity.

[0009] Further, the base limiting member is provided with a limiting structural surface perpendicular to the bottom plane of the base frame, and a height-limiting cushion block is arranged between the base limiting member and the base frame, and the thickness of the height-limiting cushion block is greater than the distance between the tip of the planing tool and the planing limiting member.

[0010] Further, the bottom of the base frame and the bottom of the planing limiting member are on the same plane.

[0011] Further, the base frame, the handle member and the planing limiting member are all formed by splicing hollow rectangular pipe fittings, the horizontal cross-section of the planing stroke cavity is rectangular, and the planing limiting member reciprocates linearly along the left and right side planes of the planing stroke cavity parallel to the planing direction.

[0012] Further, the top of the base frame is provided with a sliding plane for the handle member to contact, and the two sides of the handle member are provided with contact planes, and the contact planes are arranged parallel to the sliding plane.

[0013] Further, a first center line mark is provided in the middle of one side of the base frame close to the planing direction, and a second center line mark is provided in the middle of the side of the handle member away from the planing tool, and the first center line mark and the second center line mark are both on the same vertical plane and are both parallel to the planing direction.

[0014] Further, the bottom of the base frame is provided with a friction plane for contacting the surface of the ALC wall panel, the friction plane is parallel to the sliding plane, and the planing surface of the planing tool forms an included angle a with the friction plane, and the angle range of the included angle a is controlled between 5 degrees and 85 degrees.

[0015] Further, the length of the handle member is greater than the width of the base frame.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. The present utility model uses a grooving tool suitable for ALC wall panel construction to create a relatively shallow groove on the ALC wall panel, enabling the reinforcement member to be concealed within the ALC wall surface. After the construction is completed, it only needs to be repaired and leveled with anti-cracking mortar, ensuring the flatness of the wall surface. The overall structure of the grooving tool is simple, easy to produce and manufacture, and convenient for construction workers to use.

[0025] The following will describe in detail the embodiments of the present utility model with reference to the accompanying drawings.

[0026] As Figures 1 to 6 shown, a grooving tool applicable to ALC wall panels includes a base assembly 1 and a cutter assembly 2. The base assembly 1 includes a base frame 11 and a base limiter 12 that are convenient for fitting on the ALC wall panel. The cutter assembly 2 includes a handle member 21 and a cutter member 22 fixedly connected to the handle member 21. The base limiter 12 is fixedly connected to a side of the base frame 11 away from the handle member 21. The handle member 21 slides on the base frame 11 along the length direction of the base frame 11 and drives the cutter member 22 to perform grooving processing on the ALC wall panel.

[0027] Specifically, in some embodiments, the grooving tool is a tool for grooving on the ALC wallboard. The base assembly 1 is an auxiliary positioning assembly for the grooving tool to approach and fit on the ALC wallboard. Both the base frame 11 and the base limiting member 12 are auxiliary positioning members for facilitating the grooving tool to fit on the ALC wallboard. One side of the outer corner of the ALC wallboard is fitted with the base frame 11, and the other side is fitted with the base limiting member 12. The base frame 11 and the base limiting member 12 are fixedly connected. The construction worker clamps the base frame 11 and the base limiting member 12 together at the outer corner of the ALC wallboard to determine the grooving position of the grooving tool. The cutter assembly 2 is a cutting tool for the grooving tool to groove on the ALC wallboard. The handle member 21 is a gripping part for the construction worker to hold and operate. The cutter member 22 is arranged on the side of the handle member 21 close to the ALC wallboard and on the side close to the cutting advancing direction. The tip of the cutter member 22 is arranged towards the cutting advancing direction. During use, the construction worker holds the handle member 21 and fits it on the side of the base frame 11 away from the ALC wallboard and pushes it along the length direction of the base frame 11. The handle member 21 drives the cutter member 22 to move synchronously, so that the cutter member 22 is pushed towards the ALC wallboard. The cutter member 22 contacts and cuts the surface of the ALC wallboard to achieve the effect of cutting construction.

[0028] As Figures 3 to 5 shown, a cutting stroke cavity 111 penetrating up and down is provided in the middle of the base frame 11. The handle member 21 moves in the cutting stroke cavity 111 to limit the cutting range of the cutter member 22.

[0029] Specifically, in some embodiments, the cutting stroke cavity 111 located in the middle of the base frame 11 is a cavity for restricting the movement space of the cutter assembly 2. During use, the construction worker holds the handle member 21 and passes the cutter member 22 through the cutting stroke cavity 111, and reciprocates back and forth along the cutting direction in the cutting stroke cavity 111 to achieve the effect of cutting construction. The cutting stroke cavity 111 can prevent the cutter member 22 from easily detaching from the base frame 11 during cutting construction, which is convenient for the construction worker to exert force for cutting.

[0030] As Figure 3 and Figure 5 shown, the cutter assembly 2 includes a cutting limit member 23 for restricting the cutting direction. The cutting limit member 23 is located between the handle member 21 and the cutter member 22 and is located in the cutting stroke cavity 111.

[0031] Specifically, in some embodiments, the planing limit member 23 is an auxiliary limit member for restricting the movement of the planer blade assembly 2 within the range of the planing stroke cavity 111. The planes on the left and right sides of the planing limit member 23 are parallel to each other. The planer blade member 22 is arranged on the side of the planing limit member 23 close to the ALC wall panel and on the side close to the planing forward direction. The cutting edge of the planer blade member 22 is arranged towards the planing forward direction. During use, the construction worker holds the handle member 21 and inserts the planing limit member 23 into the planing stroke cavity 111 and extends the planer blade member 22 to the other side of the base frame 11. The planing limit member 23 reciprocates back and forth along the planing direction within the range of the planing stroke cavity 111, so that the planer blade member 22 contacts and planes the surface of the ALC wall panel, achieving the effect of planing construction. The depth of planing the ALC wall panel depends on the distance that the planer blade member 22 extends out of the base frame 11, and this distance can be adjusted by controlling the external dimensions of the planing limit member 23 to adjust the depth of planing.

[0032] As Figure 3 and Figure 5 shown, the base limit member 12 is provided with a limit structural surface 121 perpendicular to the bottom plane of the base frame 11. A height-limiting spacer 122 is provided between the base limit member 12 and the base frame 11, and the thickness of the height-limiting spacer 122 is greater than the distance between the cutting edge of the planer blade member 22 and the planing limit member 23.

[0033] Specifically, in some embodiments, it is relatively common to use a right-angle corner at the outer corner of the ALC wall panel. When the construction worker clamps the base frame 11 and the base limit member 12 together at the outer corner of the ALC wall panel, the included angle between the base frame 11 and the base limit member 12 is also a right angle to cooperate with the right-angle corner. Therefore, the base limit member 12 is provided with a limit structural surface 121 perpendicular to the bottom plane of the base frame 11 to facilitate the direct cooperation and use by the construction worker at the right-angle corner. Preferably, the base limit member 12 can be made of an angle iron 123 directly welded to the bottom plane of the base frame 11. One side plane of the angle iron 123 is perpendicular to the bottom plane of the base frame 11. The angle iron 123 is a common profile, which is convenient to process and easy to purchase, and its strength against deformation can also meet the requirements of planing use. A height-limiting spacer 122 for clearing the planer blade member 22 is also fixedly connected between the base limit member 12 and the base frame 11. The thickness of the height-limiting spacer 122 is greater than the distance that the planer blade member 22 extends out of the bottom plane of the base frame 11, so that the planer blade member 22 will not interfere and collide with the base limit member 12 during the use of the planer blade assembly 2, avoiding tool damage.

[0034] As Figure 5 and Figure 6 shown, the bottom of the base frame 11 and the bottom of the planing limit member 23 are in the same plane.

[0035] Specifically, in some embodiments, after the handle member 21 contacts the top of the base frame 11, the bottom of the planing limit member 23 is set to be in the same plane as the bottom of the base frame 11. At this time, the distance that the planing blade member 22 extends out of the bottom plane of the base frame 11 is equal to the distance that the planing blade member 22 is installed on the planing limit member 23, which is also equal to the planing depth. This is convenient for production personnel to calculate and manufacture during production, and also convenient for construction personnel to use.

[0036] As Figure 2 , Figure 3 and Figure 5 As shown, the base frame 11, the handle member 21, and the planing limit member 23 are all formed by splicing hollow rectangular pipe fittings. The horizontal cross-section of the planing stroke cavity 111 is rectangular, and the planing limit member 23 linearly reciprocates along the left and right side planes of the planing stroke cavity 111 parallel to the planing direction.

[0037] Specifically, in some embodiments, the rectangular pipe fittings can be segmented and cut from a steel square tube 3. The steel square tube 3 is a common profile, which is convenient to process and easy to purchase, and its strength against deformation can also meet the requirements of planing use. The steel square tube 3 has a hollow thin-wall design, which greatly reduces the overall weight of the grooving tool while ensuring the strength against deformation, enabling construction personnel to reduce the sense of load when using the grooving tool, reducing the gravity of natural gravity drop, and extending the effective duration of a single construction by construction personnel. The base frame 11 is formed by surrounding the outside of the planing stroke cavity 111 with multiple steel square tubes 3, and the horizontal cross-section of the planing stroke cavity 111 forms a rectangle, which is convenient for the planing stroke cavity 111 to limit the movement range of the planing tool assembly 2. Appropriately narrowing the distance between the left and right sides of the planing limit member 23 and the cavity wall of the planing stroke cavity 111 enables the planing limit member 23 to linearly reciprocate along the left and right side planes of the planing stroke cavity 111 parallel to the planing direction, thereby restricting the grooving profile to cut out an ideal shape and contour, which is convenient for construction personnel to use.

[0038] As Figure 2 and Figure 3 As shown, the top of the base frame 11 is provided with a sliding plane 112 for the handle member 21 to contact, and contact planes 211 are provided on both sides of the handle member 21. The contact planes 211 are arranged parallel to the sliding plane 112.

[0039] Specifically, in some embodiments, the top of the base frame 11 adopts a sliding plane 112 that is horizontal and smooth with the horizontal plane. The sliding plane 112 is used to stably slide and contact between the base frame 11 and the handle member 21. Since the handle member 21 directly affects the cutting trajectory of the cutting tool member 22 during pushing and pulling for cutting, the sliding of the handle member 21 on the base frame 11 needs to be as stable and constant as possible. If the surface between the sliding contacts has uneven concave-convex structures or curved surfaces, it will directly affect the cutting trajectory, and the cutting trajectory will also have concave-convex undulations or twists. The two sides of the handle member 21 for contacting the top of the base frame 11 are provided with contact planes 211 that are cooperatively connected with the sliding plane 112. The contact planes 211 are located on the side of the handle member 21 close to the base frame 11 and are parallel to the sliding plane 112. During cutting, the construction worker holds the handle member 21 to bring the contact plane 211 close to and fit with the sliding plane 112. After the contact plane 211 and the sliding plane 112 are flatly fitted, the construction worker can push the handle member 21 to drive the cutting tool member 22 to cut the surface of the ALC wall panel. The handle member 21 slides along the length direction of the base frame 11 on the sliding plane 112 through the contact plane 211 to achieve a stable cutting trajectory, making the cut section smoother and flatter, improving the quality of the cut section, and facilitating the use of the construction worker.

[0040] As Figure 1 , Figure 3 and Figure 4 shown, a first center line mark 113 is provided in the middle of one side of the base frame 11 close to the cutting direction, and a second center line mark 212 is provided in the middle of the side of the handle member 21 away from the cutting tool member 22. The first center line mark 113 and the second center line mark 212 are both in the same vertical plane and are both parallel to the cutting direction.

[0041] Specifically, in some embodiments, construction workers often need to plane a preset area and position during actual planing. However, since the color of the ALC wallboard is generally monotonous during planing, it is easy for construction workers to have phenomena such as deviation in the planing direction, incomplete planing, over-planing, or wrong planing without a reference object. A first center line mark 113 is provided in the middle of one side of the base frame 11 facing the advancing direction of planing. The first center line mark 113 is a straight line mark, line, or engraving parallel to the planing direction. The first center line mark 113 is used for construction workers to align with the preset planing track direction, strengthening the construction workers' tracking of the planing track. A second center line mark 212 is provided in the middle of the side of the handle member 21 away from the planing tool member 22. The second center line mark 212 is a straight line mark, line, or engraving parallel to the first center line mark 113. Both the first center line mark 113 and the second center line mark 212 are in the same vertical plane parallel to the planing direction. The second center line mark 212 is used for construction workers to verify the planing track direction of the first center line mark 113. During planing, the construction worker places the first center line mark 113 at the end position of the preset planing track and places the second center line mark 212 at the starting position of the preset planing track, and pushes the handle member 21 to move the second center line mark 212 towards the direction of the first center line mark 113, driving the planing tool member 22 to plane the surface of the ALC wallboard, achieving precise control of the planing track direction, improving the quality of the planed section surface, and facilitating the use of construction workers.

[0042] As Figure 6 shown, a friction plane 114 for contacting the surface of the ALC wallboard is provided at the bottom of the base frame 11. The friction plane 114 is parallel to the sliding plane 112. The planing surface of the planing tool member 22 forms an angle a221 with the friction plane 114. The angle range of the angle a221 is controlled between 0 degrees and 90 degrees.

[0043] Specifically, in some embodiments, when the planing tool 22 planes the surface of the ALC wallboard, the planing angle and the planing depth directly affect the force required for planing and the quality after planing. The side of the bottom of the base frame 11 in contact with the ALC wallboard is a friction plane 114, and the friction plane 114 is parallel to the sliding plane 112, which is convenient for construction workers to control the planing trajectory, ensuring that the push and pull of the handle 21 directly planes a plane parallel to the surface of the ALC wallboard. The plane of the planing tool 22 facing the planing forward direction forms an angle a221 with the friction plane 114. When the angle of the angle a221 is too small, the planing depth is relatively shallow, and the planing stress on the blade body of the planing tool 22 is relatively concentrated, and the blade body is prone to deformation. When the angle of the angle a221 is too large, the planing stress on the tip of the planing tool 22 is relatively concentrated, and the tip is prone to breakage. When the angle range of the angle a221 is controlled between 5 degrees and 85 degrees, the planing stress can be better dispersed on the tip and the blade body, making the blade body not easily deformed and the tip not easily broken, and the chips planed out during planing can be better convoluted into an arc shape to avoid blocking the planing stroke cavity 111, which is convenient for construction workers to use.

[0044] As Figures 1 to 4 shown, the length of the handle 21 is greater than the width of the base frame 11.

[0045] Specifically, in some embodiments, long handle parts for construction workers to hold are respectively arranged on the left and right sides of the handle 21. The long handle parts on the left and right sides of the handle 21 respectively extend out of the horizontal cross-section range of the base frame 11. The distances from the left and right ends of the handle 21 to the center of the handle 21 are the length of the handle 21, and the distances from the left and right sides of the base frame 11 to the center of the base frame 11 are the width of the base frame 11. During use, construction workers can hold the long handle parts with their hands to operate the handle 21 to slide on the base frame 11 to drive the planing tool 22 to plane the surface of the ALC wallboard. The long handle parts can also be provided with criss-cross anti-slip patterns to make it more stable when the construction workers hold them by hand, avoiding slipping during the planing process.

[0046] As Figures 1 to 6 shown, the specific implementation manner of Embodiment 1 of the present invention is as follows:

[0047] The base frame 11 respectively uses a plurality of steel square tubes 3 with a cross-section of 30mm * 30mm as rectangular pipe fittings for main body splicing. The base limit member 12 uses an angle iron 123 with a cross-section of 50mm * 50mm and is fixedly connected to the base frame 11 through a gasket 122. The plurality of steel square tubes 3 are fixedly connected and enclosed to form a planing stroke cavity 111. The sliding plane 112 is parallel to the friction plane 114. The first center line mark 113 is arranged in the middle of the base frame 11 on the side close to the planing forward direction. The limit structure surface 121 is arranged on the side of the base limit member 12 close to the planing forward direction, completing the splicing and manufacturing of the base assembly 1;

[0048] Both the handle member 21 and the planing limit member 23 are made of a steel square tube 3 with a cross-section of 30mm * 30mm as the rectangular pipe fitting for the main body splicing. The handle member 21, the planing limit member 23 and the planing tool member 22 are fixedly connected in sequence from top to bottom. The tip of the planing tool member 22 faces away from the handle member 21. The planing surface of the planing tool member 22 forms an angle a221 with the friction plane 114 of the base frame 11 for contacting the ALC wallboard, thus completing the splicing and manufacturing of the planing tool assembly 2.

[0049] During use, the construction worker fits the base assembly 1 to the ALC wallboard. The friction plane 114 contacts and fits smoothly with the surface on one side of the corner of the ALC wallboard, and the limit structure plane 121 contacts and fits smoothly with the surface on the other side of the corner of the ALC wallboard, so that the base frame 11 and the base limit member 12 are clamped on the corner of the ALC wallboard to fix the planing position. The construction worker holds the handle member 21 and inserts the planing tool member 22 through the planing stroke cavity 111 via the planing limit member 23. The tip of the planing tool member 22 faces the planing forward direction. The contact plane 211 of the handle member 21 fits on the side of the base frame 11 away from the ALC wallboard, so that the handle member 21 can slide on the base frame 11. During planing, the construction worker pushes the handle member 21 to drive the planing tool member 22 to move along the length direction of the base frame 11 via the planing limit member 23. The handle member 21 drives the planing tool member 22 to move synchronously, so that the planing tool member 22 is pushed towards the ALC wallboard. The planing limit member 23 moves within the range of the planing stroke cavity 111. The planing tool member 22 contacts and planes the surface of the ALC wallboard to achieve the effect of planing construction. After planing, the position of the ALC wallboard after planing is repaired and leveled with anti-cracking mortar.

[0050] The above only uses the embodiment to further illustrate the technical content of the present invention to make it easier for readers to understand, but it does not mean that the implementation mode of the present invention is limited to this. Any technical extension or re-creation based on the present invention is protected by the present invention. The protection scope of the present invention is subject to the claims.
