Description

Technical Field

[0001] This application relates to the field of roll material construction, and in particular to a PVC roll flooring adhesive structure. Background Technology

[0002] With the development of the building decoration industry, people's requirements for indoor floor decoration materials are increasing. PVC roll flooring, due to its advantages such as waterproofing, moisture resistance, slip resistance, easy cleaning, and rich colors, is widely used in commercial venues, public buildings, and home decoration.

[0003] Chinese utility model patent CN211037687U discloses a PVC roll flooring nested wall-mounting edge trim and its nested wall-mounting structure, including a main body, a clip head located at the top of the main body, and a top support located at the bottom of the main body; the upper part of the main body is a vertical plate, and the lower part is curved outward in an arc shape along the lower edge of the vertical plate to form a curved plate; the upper part of the vertical plate is bent inward in a rectangle to form an upper connecting groove, and the lower part is bent inward in a rectangle to form a lower connecting groove; connecting holes are spaced apart in the upper and lower connecting grooves along the length of the vertical plate; the longitudinal section of the clip head is generally S-shaped and placed horizontally, with its middle part connected to the top edge of the main body, the upper end bent upward along the top edge of the main body to form a clip head, and the lower end bent downward along the top edge of the main body to form a clip groove between it and the outer surface of the main body.

[0004] The aforementioned technologies have the following drawbacks: the top support is in line contact with the ground, resulting in unstable support, easy deformation, and consequently, cracking of the roll material. Utility Model Content

[0005] To improve the stability of the contact between the roll material and the wall or floor, this application provides a PVC roll flooring bonding structure.

[0006] The technical solution for the PVC roll flooring bonding structure provided in this application is as follows:

[0007] A PVC roll flooring adhesive structure includes a pad strip and a fixing component. The pad strip has a first contact surface, a second contact surface, and a third contact surface. The first contact surface contacts the wall, the second contact surface contacts the ground, and the third contact surface contacts the roll material. The fixing component is used to fix the pad strip.

[0008] By adopting the above technical solution, the first contact surface of the pad is attached to the wall, the second contact surface is attached to the ground, and the third contact surface is attached to the roll material. The pad is firmly installed in the corresponding position by the fixing component, so that the pad forms a stable support structure between the wall, the ground and the roll material. When subjected to pressure, the three contact surfaces of the pad disperse the pressure, changing the traditional line contact force distribution mode of the top support. The pressure is evenly transmitted in the form of surface contact, avoiding local stress concentration. When the ground or the roll material is subjected to external force, the pad remains stable by means of its own structure and the fixing effect of the fixing component, reducing deformation and thus reducing the risk of the roll material cracking due to unstable support.

[0009] Preferably, the third contact surface is arc-shaped.

[0010] By adopting the above technical solutions, the arc design can better fit the curved shape of the roll material, especially in corners and other areas, so that the pad strip and the roll material are in close contact, ensuring uniform force transmission between the two, and maintaining a smooth transition between the roll material and the wall or floor, avoiding local stress concentration due to poor contact, and reducing the risk of roll material cracking.

[0011] Preferably, the pad strip has an anti-slip layer at both the first contact surface and the second contact surface.

[0012] By adopting the above technical solution, an anti-slip layer is set on the first contact surface to increase the friction between the pad and the wall, preventing the pad from shifting horizontally due to external forces in the horizontal direction after installation. An anti-slip layer is set on the second contact surface to effectively prevent the pad from sliding on the ground. Especially when the ground is subjected to external forces such as friction and dragging, the relative position of the pad and the ground can remain unchanged, avoiding the impact of the pad sliding on the flatness and stability of the rolled material.

[0013] Preferably, the pad strip has an avoidance groove between the first contact surface and the second contact surface, and the avoidance groove has no contact with the wall or the ground.

[0014] By adopting the above technical solution, the angle between the wall and the ground during building construction is not an absolute right angle and there is a certain error. The clearance groove can adapt to this angle deviation and avoid the situation where it is difficult to fit during installation due to the rigid contact of the pad strip, so that the pad strip can better adapt to different building environments.

[0015] Preferably, the fixing component includes a card plate, a card slot, and an adhesive layer. The card plate is embedded in the wall surface, the card slot is disposed on the pad strip, the card slot is used to accommodate the card plate, and the adhesive layer is disposed between the card plate and the card slot.

[0016] By adopting the above technical solution, during the wall construction phase, the card plate is pre-embedded in the wall according to the design requirements. When installing the spacer strip, the groove on the spacer strip is aligned with the card plate pre-embedded in the wall, and then the spacer strip is moved closer to the wall, allowing the card plate to be gradually inserted into the groove. The shape and size of the groove are adapted to the card plate, providing a certain degree of constraint for the card plate. During the process of inserting the card plate into the groove, the pre-set adhesive layer between the card plate and the groove begins to function, ensuring a tight connection between the card plate and the groove.

[0017] Preferably, the end of the card plate has a rounded chamfer.

[0018] By adopting the above technical solution, the rounded chamfer makes the end of the card plate smoother. When inserting the card plate into the slot, it can reduce the friction and resistance between the card plate and the slot, avoid problems such as jamming and difficulty in insertion caused by the sharp end of the card plate, reduce the installation difficulty, and improve the construction efficiency.

[0019] Preferably, a positioning rod is connected to one side of the pad, and a positioning groove for accommodating the positioning rod is connected to the other side of the pad.

[0020] By adopting the above technical solution, during installation, the pad with the positioning rod is brought close to the pad with the positioning groove, the positioning rod is aligned with the positioning groove and inserted into it, thereby initially connecting the two adjacent pads together, determining the relative position between the pads, ensuring the neatness and accuracy of the pad laying. After the positioning rod is inserted into the positioning groove, the two form a tight fit, restricting the relative movement of adjacent pads in the horizontal direction, and enhancing the stability of the overall pad structure.

[0021] Preferably, the positioning rod is provided with a plurality of anti-detachment elastic blocks, and the inner wall of the positioning groove is provided with a plurality of anti-detachment elastic grooves for accommodating the anti-detachment elastic blocks.

[0022] By adopting the above technical solution, after the anti-detachment elastic block is inserted into the anti-detachment elastic groove, a mechanical locking structure is formed. The cooperation of multiple anti-detachment elastic blocks and anti-detachment elastic grooves constrains the positioning rod from multiple directions, restricting the positioning rod from being pulled out of the positioning groove. When adjacent pads are subjected to outward pulling force or other external forces that attempt to separate the pads, the anti-detachment elastic block and the side wall of the anti-detachment elastic groove abut against each other, and the resulting resistance can effectively resist the external force and prevent the positioning rod from detaching from the positioning groove, thereby ensuring that adjacent pads always remain firmly connected.

[0023] In summary, this application includes the following beneficial technical effects: compared with the traditional line contact of the top support, the surface contact method of the pad strip greatly increases the contact area with the wall, floor and roll material, effectively disperses pressure, and makes the support more stable.

Detailed Implementation

[0028] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0029] This utility model provides a PVC roll flooring adhesive structure, the structure of which is as follows: Figure 1 - Figure 2 As shown, it includes a pad strip 1 and a fixing component 2. The pad strip 1 is provided with a first contact surface 11, a second contact surface 12 and a third contact surface 13. The first contact surface 11 contacts the wall surface 3, the second contact surface 12 contacts the ground surface 4, and the third contact surface 13 contacts the roll material 5. The fixing component 2 is used to fix the pad strip 1.

[0030] In use, the first contact surface 11 of the pad 1 is attached to the wall surface 3, the second contact surface 12 is attached to the ground surface 4, and the third contact surface 13 is attached to the roll material 5. The pad 1 is firmly installed in the corresponding position by the fixing component 2, so that the pad 1 forms a stable support structure between the wall surface 3, the ground surface 4 and the roll material 5. When subjected to pressure, the three contact surfaces of the pad 1 disperse the pressure, changing the traditional line contact force distribution mode of the top support. The pressure is evenly transmitted in the form of surface contact, avoiding local stress concentration. When the ground surface 4 or the roll material 5 is subjected to external force, the pad 1 remains stable by its own structure and the fixing effect of the fixing component 2, reducing deformation and thus reducing the risk of the roll material 5 cracking due to unstable support.

[0031] In this invention, compared with the traditional line contact of the top support, the surface contact method of the pad strip 1 greatly increases the contact area with the wall 3, the ground 4 and the roll material 5, effectively dispersing pressure and making the support more stable.

[0032] To ensure a smooth transition between the roll material 5 and the floor 4, padding strip 1, and wall 3, please refer to... Figure 1 In a preferred embodiment, the third contact surface 13 is arc-shaped.

[0033] When in use, the arc design can better fit the curved shape of the roll material 5, especially in corners and other areas, so that the pad strip 1 and the roll material 5 are in close contact, ensuring uniform force transmission between the two, and maintaining a smooth transition between the roll material 5 and the wall surface 3 and the floor 4, avoiding local stress concentration due to poor contact, and reducing the risk of cracking of the roll material 5.

[0034] To increase the friction between pad 1 and the ground 4 and wall 3, please refer to... Figure 1 In a preferred embodiment, the pad strip 1 is provided with anti-slip layers 14 at both the first contact surface 11 and the second contact surface 12, and the anti-slip layers 14 are arrayed anti-slip grooves.

[0035] During use, an anti-slip layer 14 is provided on the first contact surface 11 to increase the friction between the pad 1 and the wall 3, preventing the pad 1 from shifting horizontally due to external forces in the horizontal direction after installation. An anti-slip layer 14 is provided on the second contact surface 12 to effectively prevent the pad 1 from sliding on the ground 4. Especially when the ground 4 is subjected to external forces such as friction and dragging, the relative position of the pad 1 and the ground 4 can remain unchanged, avoiding the impact of the sliding of the pad 1 on the flatness and stability of the roll material 5.

[0036] To ensure a tighter fit between the pad 1 and the ground 4 and wall 3, please refer to... Figure 1 In a preferred embodiment, a clearance groove 15 is provided on the pad strip 1 between the first contact surface 11 and the second contact surface 12, and the clearance groove 15 has no contact with the wall surface 3 or the ground surface 4.

[0037] During use, the angle between the wall 3 and the ground 4 is not an absolute right angle during construction and there is a certain error. The relief groove 15 can adapt to this angle deviation and avoid the situation that is difficult to fit during installation due to the rigid contact of the pad strip 1, so that the pad strip 1 can better adapt to different building environments.

[0038] To secure the spacer strip 1 to the wall surface 3, please refer to... Figure 1 In a preferred embodiment, the fixing component 2 includes a card plate 21, a card slot 22 and an adhesive layer 23. The card plate 21 is embedded in the wall surface 3, the card slot 22 is provided on the pad strip 1 and is used to accommodate the card plate 21. The adhesive layer 23 is provided between the card plate 21 and the card slot 22.

[0039] During use, in the construction phase of wall surface 3, the card plate 21 is pre-embedded in the wall according to the design requirements. When installing the spacer strip 1, the slot 22 on the spacer strip 1 is aligned with the card plate 21 pre-embedded in wall surface 3. Then, the spacer strip 1 is moved closer to wall surface 3, so that the card plate 21 is gradually inserted into the slot 22. The shape and size of the slot 22 are adapted to the card plate 21, which can provide a certain constraint for the card plate 21. During the process of inserting the card plate 21 into the slot 22, the pre-set adhesive layer 23 between the card plate 21 and the slot 22 begins to function, making the card plate 21 and the slot 22 tightly connected together.

[0040] To make it easier for the card plate 21 to slide into the slot 22 on the pad strip 1, please refer to... Figure 1 In a preferred embodiment, the end of the card plate 21 is provided with a rounded chamfer.

[0041] When in use, the rounded chamfer makes the end of the card plate 21 smoother. When inserting the card plate 21 into the card slot 22, it can reduce the friction and resistance between the card plate 21 and the card slot 22, avoid problems such as jamming and difficulty in insertion caused by the sharp end of the card plate 21, reduce the difficulty of installation, and improve the construction efficiency.

[0042] To improve the overall integrity between multiple spacer strips 1, please refer to Figure 2 In a preferred embodiment, a positioning rod 6 is connected to one side of the pad 1, and a positioning groove 61 for accommodating the positioning rod 6 is connected to the other side of the pad 1.

[0043] During use and installation, the pad 1 with the positioning rod 6 is brought close to the pad 1 with the positioning groove 61. The positioning rod 6 is aligned with the positioning groove 61 and inserted into it, thereby initially connecting the two adjacent pads 1 together, determining the relative position between the pads 1, and ensuring the neatness and accuracy of the pads 1. After the positioning rod 6 is inserted into the positioning groove 61, the two form a tight fit, restricting the relative movement of adjacent pads 1 in the horizontal direction and enhancing the stability of the overall structure of the pads 1.

[0044] To reduce the possibility of the positioning rod 6 coming out of the positioning groove 61, please refer to... Figure 2 In a preferred embodiment, the positioning rod 6 is provided with a plurality of anti-detachment elastic blocks 7, and the inner wall of the positioning groove 61 is provided with a plurality of anti-detachment elastic grooves 71 for accommodating the anti-detachment elastic blocks 7.

[0045] In use, after the anti-detachment elastic block 7 is inserted into the anti-detachment elastic groove 71, a mechanical locking structure is formed. The cooperation of multiple anti-detachment elastic blocks 7 and anti-detachment elastic groove 71 constrains the positioning rod 6 from multiple directions, preventing the positioning rod 6 from being pulled out of the positioning groove 61. When the adjacent pad 1 is subjected to an outward pulling force or other external force that attempts to separate the pad 1, the anti-detachment elastic block 7 and the side wall of the anti-detachment elastic groove 71 abut against each other, and the resulting resistance can effectively resist the external force and prevent the positioning rod 6 from disengaging from the positioning groove 61, thereby ensuring that the adjacent pad 1 always maintains a stable connection.

[0046] The implementation principle of the PVC roll flooring adhesive structure in this application embodiment is as follows: the first contact surface 11 of the pad strip 1 is attached to the wall surface 3, the second contact surface 12 is attached to the ground surface 4, and the third contact surface 13 is attached to the roll material 5. The pad strip 1 is firmly installed in the corresponding position by the fixing component 2, so that the pad strip 1 forms a stable support structure between the wall surface 3, the ground surface 4 and the roll material 5. When subjected to pressure, the three contact surfaces of the pad strip 1 disperse the pressure, changing the traditional line contact force distribution mode of the top support. The pressure is evenly transmitted in the form of surface contact, avoiding local stress concentration. When the ground surface 4 or the roll material 5 is subjected to external force, the pad strip 1 remains stable by its own structure and the fixing effect of the fixing component 2, reducing deformation, thereby reducing the risk of the roll material 5 cracking due to unstable support.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
