Description

Technical Field

[0001] The utility model relates to the technical field of construction, and particularly relates to a grooving tool for the part where the adhesive tape is pasted on an ALC strip board. Background Art

[0002] In the construction of ALC strip boards, in order to maintain the stability of the strip boards and prevent earthquake, construction columns must be set at key parts of the wall. However, due to the formwork sealing conditions at the positions of the construction columns, the formwork sealing quality at this place is affected by conditions. Generally, on-site construction operations take measures such as pasting adhesive tapes at the joints to prevent the leakage of concrete caused by the imperfect formwork sealing. However, taking this measure will cause new quality problems. Because the adhesive tape has a certain thickness, the increased thickness here will cause the overall flatness of the strip board wall not to meet the specification requirements. Content of the Utility Model

[0003] In order to solve the problem that the wall flatness does not meet the standard, the utility model provides a grooving tool for the part where the adhesive tape is pasted on an ALC strip board, which mainly includes a hand-held grip, a fixing plate, and a plurality of blades. Each blade is installed on both sides of the lower surface of the fixing plate through an adjusting component to form a groove. The distance between the blades can be adjusted through the adjusting component, so as to adjust the width dimension of the groove, so as to be flexibly applied according to the sizes of the strip board and the wall on site, and be applicable to grooving ALC walls with different thicknesses.

[0004] The above technical purpose of the utility model is achieved through the following technical solutions:

[0005] A grooving tool for the part where the adhesive tape is pasted on an ALC strip board includes a fixing plate, a hand-held grip located on the upper surface of the fixing plate, and a plurality of blades arranged on the lower surface of the fixing plate. Each blade is installed on both sides of the lower surface of the fixing plate through an adjusting component to form a groove, and the distance between the two blades on both sides is adjusted through the adjusting component to adjust the groove size.

[0006] As a further solution of the utility model, the adjusting component includes blade supports installed on both sides of the lower surface of the fixing plate, and the blades are located on the blade supports.

[0007] As a further solution of the utility model, the blades are embedded in the blade supports or integrally formed, and the blades are fixed on the fixing plate through the blade supports.

[0008] As a further solution of the utility model, a plurality of limiting holes are provided on the fixing plate for fixing the blade supports.

[0009] As a further solution of the utility model, screw holes are provided on the blade supports and are fixed on the fixing plate through screws, and the positions and quantities of the blades are adjusted through a plurality of limiting holes.

[0010] As a further solution of the present utility model, the blade is a pyramid blade, and the size of the scraping groove can be adjusted by changing the size.

[0011] As a further solution of the present utility model, grip struts are provided at both ends of the hand-held grip and are fixed to the fixing plate through the grip struts.

[0012] As a further solution of the present utility model, the two grip struts are symmetrically fixed to the side of the fixing plate, and the hand-held grip is located at the center of the fixing plate.

[0013] As a further solution of the present utility model, a plurality of the limiting holes are symmetrically distributed on the fixing plate with the hand-held grip as the center.

[0014] As a further solution of the present utility model, different skin-friendly materials can be used to wrap the hand-held grip to facilitate the user to exert force on the tool.

[0015] As a further solution of the present utility model, the connection mode between the grip strut and the fixing plate can also be adjusted, and welding or nut connection can be adopted.

[0016] As a further solution of the present utility model, the blade is a pyramid blade, and the depth of the blade edge is usually set at 3 mm. Since the thickness of the tape is 3 mm, if the thickness of the tape changes, the depth of the blade edge can also change accordingly.

[0017] As a further solution of the present utility model, the inner side of the blade strut is arc-shaped to reduce the friction when the tool moves on the wall.

[0018] Compared with the existing technology, the beneficial effects of the present utility model are as follows:

[0019] The present utility model provides a scraping groove tool for the tape sticking part of the ALC strip board, which can be used flexibly. The size of the scraping groove of the scraping groove tool can be adjusted according to the size of the ALC wall to be suitable for scraping grooves of ALC walls with different thicknesses.

[0020] Compared with the existing construction tools, it can avoid the problem of uneven wall surface caused by sticking double-sided tape at the construction column position of the ALC strip board to prevent concrete leakage. Since the flatness of the ALC strip board wall must be controlled within ±3 mm, if double-sided tape is directly stuck on the ALC strip board, due to the thickness of the double-sided tape being about 3 mm, the flatness here will not meet the standard and secondary grinding is required. This utility model can effectively avoid secondary grinding and improve the construction quality of the wall.

[0021] The present utility model has better economy and good quality effect in the construction environment and has great popularization value. Description of the Drawings

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model in combination with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the scope of protection of the present utility model.

[0028] As Figures 1 to 3 shown, a grooving tool for the tape - pasting part of an ALC slab of the present utility model includes a fixed plate 5, a hand - held grip 3, and more than four blades 7. The hand - held grip 3 is arranged on the upper surface of the fixed plate 5 through a grip support 2. Each blade 7 is fixed on both sides of the lower surface of the fixed plate 5 through an adjustment assembly, and the position and blade spacing of the two - side blades 7 are adjusted through the adjustment assembly, thereby changing the grooving size. The adjustment assembly includes blade supports 4 installed on both sides of the lower surface of the fixed plate 5, and the blade 7 is located on the blade support 4.

[0029] The fixed plate 5 is provided with a plurality of limiting holes 6 for fixing the blade 7 to be applicable to grooving ALC walls with different thicknesses. Specifically, the blade support 4 is provided with screw holes and is fixed on the limiting holes 6 of the fixed plate 5 through screws, and the position and number of the blades 7 are adjusted through the plurality of limiting holes 6.

[0030] As Figure 2As shown, the limiting holes 6 of this embodiment are symmetrically distributed on both sides of the edge of the fixing plate 5. The distance between the limiting holes on both sides can be set according to the size of the ALC strip board. At the same time, the size of the blade 7 on the blade support 4 needs to be considered, etc.

[0031] In this embodiment, eight limiting holes 6 are provided on the fixing plate 5. The eight limiting holes 6 are symmetrically distributed on the fixing plate 5 with the hand-held grip 3 as the center, as Figure 2 shown.

[0032] The common thicknesses of ALC strip boards are 100 and 200 mm. The distance between the limiting holes 6 is determined according to the inner spacing of 100 mm or 200 mm of the blade support 4. If strip boards of different sizes appear, the limiting holes 6 can also be further improved.

[0033] The inner right angle of the blade support 4 is processed into an arc to reduce the friction when the utility model moves on the wall. A detachable screw 1 is provided in the middle of the blade support 4. The blade 7 can be embedded on the blade support 4 or integrally formed.

[0034] As a preference, the blade 7 adopts a pyramid blade, and the size of the scraping groove can be adjusted by changing the size to meet the installation of the tape. Generally, the size of the pyramid blade usually has a cutting edge depth set at 3 mm because the tape thickness is 3 mm. If the tape thickness changes, the cutting edge depth can also change accordingly.

[0035] The hand-held grip 3 can be wrapped with different skin-friendly materials to facilitate the user to exert force on the tool. The material of the hand-held grip 3 in this embodiment is made of cylindrical hollow stainless steel. The fixing plate 5 is also made of stainless steel, such as made of galvanized steel plate, and the four corners are polished. The two ends of the hand-held grip 3 are fixed with the grip supports 2, and are fixed on the fixing plate 5 through the grip supports 2. The length of the hand-held grip 3 is approximately equal to the width of the fixing plate 5. The two grip supports 2 are fixed on both sides of the fixing plate 5, and the hand-held grip 3 is located at the center of the fixing plate 5, which is convenient for the user to hold the scraping groove tool of the utility model and make it exert force along the expected track.

[0036] The connection mode between the two grip supports 2 and the fixing plate 5 can be welding or an adjustable connection mode, such as nut connection.

[0037] The utility model is mainly used for scraping grooves at the tape-pasting parts when constructing columns by casting ALC slats, so as to solve the problem that the concrete protrudes from the wall surface due to tape pasting. The utility model can effectively control the flatness at the junction of the two, providing good technical conditions for the plaster-free process of ALC slats. The steps for installing a scraping groove tool for the tape-pasting parts of ALC slats are as follows:

[0038] First, according to the thickness of the ALC slats at the construction site, adjust the detachable fixing screw 1 as shown in the figure, move the blade support 4 to the required limit hole 6, and then fix the detachable fixing screw 1 to the blade support 4.

[0039] After completing the above steps, the construction worker holds the hand grip 3 and adjusts the hand grip 3 to be parallel to the vertical surface of the ALC slat.

[0040] Then place the scraping groove tool above the side of the ALC slat, and then press the lower surface of the fixing plate 5 and the blade 7 tightly against the side of the ALC partition wall. Push the hand grip 3 to make the scraping groove tool slide up and down to complete the required operation process. After completing the above operations, paste the tape at the corresponding position, and then install the formwork to carry out concrete pouring.

[0041] For those skilled in the art, it is obvious that this application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of this application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of this application is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in this application. Any reference signs in the claims should not be regarded as limiting the claimed rights involved.
