Description

Technical Field

[0001] This utility model belongs to the technical field of road construction equipment, and in particular relates to a jointing tool for stone pavement. Background Technology

[0002] In order to enhance aesthetics and durability, modern gardens, scenic areas, and street surfaces use blocks of stone for paving. The stones are cut to form regular edges and corners. During paving, the stones are spliced ​​together to form the road surface. To prevent the stones from shifting, gaps are left between them to be filled with concrete mortar.

[0003] The jointing technique for stone pavements mainly involves pressing the mortar between the stones to create joints. After the mortar fills the gaps, before it fully dries and hardens, a jointing tool is used to press the mortar at the joint opening, forming an arc-shaped groove. This process removes excess mortar, resulting in a tighter bond between the mortar and the stones, a neat appearance, and improved drainage. Currently, the gaps between stones in existing stone pavements vary, typically between 5-15mm. Jointing strips used for jointing cannot perfectly accommodate these gaps. Existing detachable jointing strips use a plug-in installation method. These strips have different sized pressing and fixing parts, with the fixing part fitting into the mounting groove. During installation, the fixing part requires external force to press against the mounting groove, requiring a certain amount of force. This makes the detachable installation of the strip inconvenient and unstable. Utility Model Content

[0004] The purpose of this utility model is to provide a tool for grouting stone pavements, which solves the problems of slow operation and poor forming quality caused by manual grouting of large horizontal and vertical joints.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A stone pavement grouting tool includes a first iron plate and a second iron plate, which are spliced ​​together to form a whole iron plate. An adhesive strip is detachably installed between the first iron plate and the second iron plate on both sides. The projection of the bottom of the adhesive strip in the length direction is an arc shape. A clamping groove is formed on the mating side of the first iron plate and the second iron plate for clamping and fixing the rubber strip; The front of the iron plate is flat, and a handle is installed on the back.

[0006] Furthermore, the first iron plate is bent at 90° on one side of the clamping groove to form a first folding plate, the second iron plate is bent at 90° on one side of the clamping groove to form a second folding plate, the end of the first folding plate is bent at 90° to form a third folding plate, the handle is fixed to the third folding plate, and a clamping groove is formed between the first folding plate and the second folding plate.

[0007] Furthermore, the first folding plate is vertically fixed with a positioning rod, and the second folding plate has a positioning hole for the positioning rod to pass through. The free end of the positioning rod is threaded and is tightened and fixed by a nut. The adhesive strip has a groove for the positioning rod to pass through. The first and second folding plates have anti-slip textures on one side of the corresponding clamping groove. The front and rear sides of the adhesive strip are both arc-shaped surfaces, and an expansion joint is formed on the upper side of the adhesive strip.

[0008] Furthermore, the handle is L-shaped, with a vertical section connecting to the third folding plate and a horizontal section for gripping, and a wooden handle fixed to the horizontal section.

[0009] This invention offers the following advantages: During use, the adhesive strip can be replaced according to the size of the gaps in the road surface stones. A suitable thickness of adhesive strip is selected, and it is clamped and fixed by the first and second iron plates on both sides. After mortar is poured into the stone gaps, the iron plates press into the gaps and move along the length of the gaps. The protruding arc-shaped part of the adhesive strip corresponds to the stone gaps, compressing the gaps to form a groove with an arc-shaped bottom between the stones. Excess mortar is scraped off by the end of the iron plate. The plate mainly serves to press, support, position, and smooth out excess mortar. It can form a concave joint in one step and includes a compaction and finishing function. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] like Figures 1-3As shown: A stone pavement grouting tool includes a first iron plate 1 and a second iron plate 2, which are used to splice each other to form an integral iron plate. A rubber strip 3 is detachably installed between the first iron plate 1 and the second iron plate 2 on both sides. The projection of the bottom of the rubber strip 3 in the corresponding length direction is an arc shape. The first iron plate 1 and the second iron plate 2 form a clamping groove on their mating side, which is used to clamp and fix the rubber strip 3. The front of the iron plate is flat, and the back is fitted with a handle 4.

[0017] The resulting iron plate is rectangular in shape, formed by splicing the first and second iron plates on both sides. The splicing seam is located at the center line along the length direction, forming a clamping groove. The clamping groove is a long strip-shaped groove used to clamp and fix the adhesive strip. The adhesive strip is strip-shaped with flat sides for easy clamping and fixing, and has a protruding arc surface at the bottom, forming a strip-shaped protrusion on the flat side of the iron plate. The cross-sectional thickness of the adhesive strip varies from 3 to 20 mm.

[0018] During use, the rubber strip can be replaced according to the size of the gaps in the road stones. Selecting the appropriate thickness, it is clamped and fixed by the first and second iron plates on both sides. After mortar is poured into the stone gaps, the iron plates are pressed into the gaps and moved along the length of the gaps. The protruding curved part of the rubber strip corresponds to the stone gaps, compressing the gaps to form a groove with an arc-shaped bottom between the stones. Excess mortar is scraped off by the end of the iron plate. The plate mainly serves to press, support, position, and smooth out excess mortar. It can form concave joints in one step and includes a compaction and finishing function.

[0019] like Figure 1 As shown: The first iron plate 1 is bent at a 90° angle to one side of the clamping groove to form a first folded plate 11; the second iron plate 2 is bent at a 90° angle to one side of the clamping groove to form a second folded plate 22; the end of the first folded plate 11 is bent at a 90° angle to form a third folded plate 13; the handle 4 is fixed to the third folded plate 13; a clamping groove is formed between the first folded plate 11 and the second folded plate 22. The first iron plate has two 90° bends on the corresponding side to form a groove for accommodating the adhesive strip; the second folded plate can slide and adjust within the groove to adjust the width of the clamping groove. The bent portion of the first plate forms a distinct ridge structure on the back side of the iron plate.

[0020] The first folding plate 11 is vertically fixed with a positioning rod 14. The second folding plate 22 has a positioning hole 21 for the positioning rod 14 to pass through. The free end of the positioning rod 14 is threaded and is tightened and fixed by a nut 23. The adhesive strip 3 has a groove 31 for the positioning rod 14 to pass through. The positioning rod is distributed on both sides. By cooperating with the positioning hole and screwing in the nut, the size of the clamping groove is adjusted. The adhesive strip is fixed by compression, which is more convenient than the traditional plug-and-play installation. The first folding plate 11 and the second folding plate 22 have anti-slip texture on one side of the clamping groove. This improves the stability of the clamping adhesive strip and makes it less likely to loosen. The front and rear sides of the adhesive strip 3 are both arc-shaped surfaces, and an expansion joint 32 is opened on the upper side of the adhesive strip 3. The arc-shaped surfaces on the front and rear sides and the bottom arc-shaped surface of the adhesive strip have arc transitions at the corresponding corner positions, which can push excess mortar to both sides when the adhesive strip is pressed and pushed in. The expansion joint has a sandwich structure, which is used for clamping and compressing deformation. Depending on the size of the stone gap, the rubber strip can be appropriately squeezed to fit the concave joint. For example, for a 5mm concave joint, if an 8mm wide rubber strip has been installed, the clamping groove can be appropriately reduced to deform and compress the rubber strip to 5mm, so that the rubber strip does not need to be replaced frequently.

[0021] like Figure 1 As shown: the handle 4 is L-shaped, the section connecting to the third folding plate 13 is a vertical section, the grip section is a horizontal section, and a wooden handle is fixed to the horizontal section.

[0022] These embodiments are selected and specifically described in this specification in order to better explain the principles and practical applications of this utility model, so that those skilled in the art can better understand and utilize this utility model.
