Description

Technical Field

[0001] This utility model relates to the field of granite slab paving technology, specifically to a granite slab paving joint clamping tool. Background Technology

[0002] Currently, natural stone slabs such as granite are widely used in floor paving due to their advantages such as hardness, natural color, and durability. During construction, in order to ensure that the gaps between the slabs are uniform, aesthetically pleasing, and meet the requirements of thermal expansion and contraction, special gap-sealing tools are needed for positioning and laying.

[0003] In current construction, ordinary plastic "cross-shaped" joint clamps are commonly used. These clamps have a cross-shaped structure and are inserted into the cross joints of four adjacent boards to control the width of both longitudinal and transverse gaps. However, in practice, in addition to cross-shaped gaps, there are also straight gaps between boards, which these "cross-shaped" joint clamps cannot correct. Furthermore, when laying boards, it is also necessary to control the flatness of adjacent boards, that is, to control the height difference between adjacent boards. However, these joint clamps are difficult to calibrate and check for height differences. In delicate construction that requires simultaneous gap positioning and height calibration, other types of leveling devices must be used, which increases the number of steps, affects construction efficiency, and makes the construction tools numerous and inconvenient to manage.

[0022] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] like Figures 1-3 The invention relates to a granite slab paving joint clamping tool, which includes a central support plate 1, a straight plate 2, and a cross plate 3. The straight plate 2 is fixedly installed on the upper surface of the central support plate 1, and the cross plate 3 is fixedly installed on the lower surface of the central support plate 1. The central support plate 1, the straight plate 2, and the cross plate 3 are all connected and fixed by adhesive. The central support plate 1 and the straight plate 2 are both cuboid structures, and the cross plate 3 has a cross-shaped cross section. This structural design facilitates the correction and positioning of the gaps between the slabs.

[0024] The aforementioned granite slab paving joint clamping tool, by fixing the straight plate 2 on the upper surface of the intermediate support plate 1 and the cross plate 3 on the lower surface of the intermediate support plate 1, allows for the positioning and paving of straight joint structures using the straight plate 2, while the cross plate 3 can be used to position and pave cross joints and T-joints. This enables the paving of different joint clamping slabs, ensuring uniform joint width and aesthetically pleasing lines. Furthermore, the intermediate support plate 1 can be used directly to check and calibrate the height of adjacent jointing slabs, eliminating the need for other tools, reducing steps, and ensuring construction efficiency.

[0025] like Figure 2As shown, in this embodiment, the length of the intermediate support plate 1 is 20mm; the width of the intermediate support plate 1 is 20mm; the thickness of the intermediate support plate 1 is 3mm; the intermediate support plate 1 is the main support structure of the entire gap-sealing tool. The straight plate 2 and the cross plate 3 are both glued and fixed to the intermediate support plate 1. Therefore, while positioning and laying the gaps between the boards, the height of adjacent boards can be checked and calibrated by utilizing the cuboid structure of the intermediate support plate 1. The operation is simple and the work efficiency is high. The length, width and thickness parameters of the intermediate support plate 1 can be adjusted according to the actual positioning and usage requirements.

[0026] like Figure 2 As shown, in this embodiment, the length of the straight board 2 is 10mm; the height of the straight board 2 is 5mm; and the width of the straight board 2 is 1mm. The straight board 2 is mainly used to position the straight joint structure of adjacent boards. The traditional cross structure cannot be applied to the straight joint structure due to structural reasons. However, the straight board 2 can be used to position the straight joint structure, which is compatible with the laying of narrow board structures, increasing the practicality and functionality of the joint clamping tool. In addition, the width of the straight board 2 can be adjusted according to the required gap width between the boards. It can generally be 2mm, 3mm, 5mm or 10mm, or other widths.

[0027] like Figure 3 As shown, in this embodiment, the length of the cross plate 3 is 20mm; the width of the cross plate 3 is 20mm; the height of the cross plate 3 is 5mm; the thickness of the cross plate 3 can be adjusted according to the required gap width between the boards, generally 1mm, 2mm, 3mm, 5mm or 10mm, or other widths. The cross plate 3 is mainly used to position cross joints and T-joint structures. On the basis that the joint clamping tool already has the ability to position and install straight joint structures, the addition of cross joint and T-joint structures greatly increases the practicality and flexibility of the joint clamping tool. Moreover, the straight plate 2 and the cross plate 3 are located on the two sides of the middle support plate 1 respectively, and the two do not interfere with each other. When using, the conversion can be achieved simply by flipping the joint clamping tool.

[0028] like Figures 1-3As shown, in this embodiment, firstly, according to the gap width requirements during the panel installation process, a gap-clamping tool of corresponding thickness is selected. For panel installation with a straight gap structure, the straight plate 2 is manually inserted into the corresponding gap, and the contact between the panel and the straight plate 2 is adjusted to meet the gap width requirements. The flatness of adjacent panels is checked using the intermediate support plate 1. For panel installation with a T-shaped gap structure, any one of the cross plates 3 is inserted into the corresponding gap, and then the other plate is used to hold the adjacent panel, thus achieving the positioning installation of the T-shaped gap structure. Then, the contact between the panel and the cross plate 3 is adjusted to meet the gap width requirements, and the flatness of adjacent panels is checked using the intermediate support plate 1. For panel installation with a cross-shaped gap structure, the cross plate 3 is inserted into the corresponding gap, and the contact between the panel and the cross plate 3 is adjusted to meet the gap width requirements. The flatness of adjacent panels is checked using the intermediate support plate 1. The intermediate support plate 1, the straight plate 2, and the cross plate 3 are all made of acrylic. Acrylic has high structural strength and is not easily damaged, allowing the joint clamping tool to be reused multiple times. However, the existing "cross-shaped" joint clamps are disposable plastic products made of ordinary plastic. Their structural strength is limited, and when installing heavy granite slabs with sharp edges, they are easily broken or deformed due to the pressure, collision, or knocking of the slabs, making them unusable, increasing construction costs and material waste. At the same time, broken plastic fragments may remain in the gaps, affecting the subsequent grouting quality. Moreover, when subjected to the pressure of heavy slabs above, the existing joint clamps are prone to bending or displacement, making it difficult to ensure that the width of all gaps remains consistent. This often leads to uneven width and crooked lines in the final slab joints, seriously affecting the overall appearance. Therefore, by changing the thickness of the intermediate support plate 1, the straight plate 2, and the cross plate 3, the structure of the joint clamping tool is made more stable, improving the paving effect.

[0029] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
