Description

Technical Field

[0001] This utility model relates to the field of adhesive strip technology, and in particular to an adhesive strip structure for floor expansion joints. Background Technology

[0002] In building structures, the installation of expansion joints is crucial for mitigating structural stress caused by factors such as temperature changes, settlement, or earthquakes. Traditional expansion joint treatments often use simple rubber strips or rigid filling materials, which have significant drawbacks: rubber materials easily lose elasticity due to long-term compression and deformation, leading to seal failure; rigid materials lack buffering capacity and are difficult to adapt to multi-directional displacement; and fixing methods often rely on adhesives or simple clips, which are prone to loosening under vibration.

[0003] Therefore, there is an urgent need for an integrated expansion joint treatment solution that has good cushioning, is easy to install, and can be reliably fixed. Utility Model Content

[0004] The present invention aims to at least partially solve one of the problems existing in the existing related technologies. To this end, the present invention proposes a floor expansion joint adhesive strip structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A floor expansion joint rubber strip structure includes an expansion joint formed between two walls, and a rubber strip body is provided between the expansion joint. The rubber strip body includes a fixing part and a buffer expansion part connected between the two fixing parts. The fixing part is fixed to the upper end of the wall, and the buffer expansion part is provided in the expansion joint.

[0007] In some embodiments, the buffer telescopic portion includes a side buffer portion and an intermediate buffer portion disposed between the two side buffer portions, and a buffer notch is provided between the lower parts of the two side buffer portions and the intermediate buffer portion. A plurality of first buffer cavities are provided in both the side buffer portion and the intermediate buffer portion.

[0008] In some embodiments, a plurality of second buffer cavities are laterally spaced within the fixing portion.

[0009] In some embodiments, a plurality of V-shaped notches are spaced laterally at the upper end of the fixing part, and the plurality of V-shaped notches and a plurality of second buffer cavities are arranged sequentially at intervals.

[0010] In some embodiments, an aluminum alloy base is provided on the wall, and the fixing part is fixed to the aluminum alloy base by screws.

[0011] In some embodiments, the aluminum alloy base includes a base plate fixed to the upper end of the wall by bolts, a support plate is provided at one end of the base plate and located in the expansion joint, a horizontal plate is provided at the lower end of the support plate, a side buffer is provided at the upper end of the horizontal plate, and one end of the support plate abuts against one side of the side buffer.

[0012] In some embodiments, a limiting plate is provided at one end of the base plate away from the support plate, and the outer end of the fixing part abuts against the inner side of the limiting plate.

[0013] In some embodiments, an aluminum alloy pressure strip is provided in the fixing part, and the screw passes through the aluminum alloy pressure strip and is threadedly connected to the base plate.

[0014] In some embodiments, a waterstop is also provided in the expansion joint, and the waterstop is located below the buffer expansion joint.

[0015] In some embodiments, connecting vertical plates are provided at both ends of the waterstop, and a connecting horizontal plate is provided at the upper end of the connecting vertical plates, the connecting horizontal plate being pressed against the lower side of the aluminum alloy base.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] By setting up the fixed part and the buffer expansion part, the fixed part focuses on anchoring force, while the buffer end is dedicated to deformation absorption. This can effectively buffer the damage caused by thermal expansion and contraction between buildings, and also effectively prevent the rubber strip from falling off the expansion joint, significantly extending the service life of the rubber strip. In addition, the fixed part and the buffer expansion part adopt a prefabricated integrated molding process, and on-site installation can be completed simply by anchoring the two fixed parts to the wall with screws. Attached Figure Description

[0018] Fig. 1 This is a schematic diagram of the structure of the rubber strip body after installation.

[0019] Fig. 2 This is an exploded structural diagram of the present invention. Detailed Implementation

[0020] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0021] like Figs. 1-2The floor expansion joint rubber strip structure shown includes an expansion joint 2 formed between two walls 1, and a rubber strip body 3 is provided between the expansion joint 2. The rubber strip body 3 includes a fixing part 4 and a buffer expansion part 5 connected between the two fixing parts 4. The fixing part 4 is fixed to the upper end of the wall 1, and the buffer expansion part 5 is provided in the expansion joint 2.

[0022] According to the above structure, the fixed part 4 and the buffer expansion part 5 are set so that the fixed part 4 focuses on anchoring force and the buffer end is dedicated to deformation absorption. This can effectively buffer the damage caused by thermal expansion and contraction between buildings, and also effectively prevent the rubber strip from falling off the expansion joint, significantly extending the service life of the rubber strip. In addition, the fixed part 4 and the buffer expansion part 5 adopt a prefabricated integrated molding process. On-site installation can be completed by simply anchoring the two fixed parts to the wall 1 with screws.

[0023] By designing the rubber strip body 3 as a combination of a fixing part 4 and a buffer expansion part 5, it not only achieves stable fixation to the wall 1, but also effectively absorbs the expansion and contraction deformation of the floor caused by factors such as temperature and load through the buffer expansion part 5, avoiding the tearing of the rubber strip or damage to the wall due to stress concentration, and significantly improving the adaptability and durability of the expansion joint.

[0024] Furthermore, the buffer telescopic part 5 includes side buffer parts 21 spaced apart and an intermediate buffer part 22 disposed between the two side buffer parts 21. A buffer notch 23 is provided between the lower parts of the two side buffer parts 21 and the intermediate buffer part 22. The buffer notch 23 provides deformation space, allowing the rubber strip to freely expand and contract in the horizontal and vertical directions. Multiple first buffer cavities 24 are provided in both the side buffer parts 21 and the intermediate buffer part 22. The first buffer cavities 24 can disperse stress, enhance elasticity, reduce fatigue damage of the rubber strip, and extend its service life.

[0025] Thus, through the layered design of the side buffer section 21 and the middle buffer section 22, combined with the lower buffer notch 21 and the internal first buffer cavity 24, a multi-level buffer mechanism is formed.

[0026] Furthermore, a plurality of second buffer cavities 31 are laterally spaced within the fixing part 4, and a plurality of V-shaped notches 41 are laterally spaced at the upper end of the fixing part 4. The plurality of V-shaped notches 41 and the plurality of second buffer cavities 31 are arranged sequentially at intervals. The provision of second buffer cavities 31 within the fixing part 4 reduces the overall weight of the fixing part 4 and gives it a certain degree of elasticity, avoiding stress concentration at the fixing part due to slight displacement of the wall, and improving the cooperative deformation capability of the adhesive strip and the wall.

[0027] In this utility model, an aluminum alloy base 51 is provided on the wall 1. The aluminum alloy base 51 is corrosion resistant, has high strength, and ensures long-term stability.

[0028] The fixing part 4 is fixed to the aluminum alloy base 51 by screws 61. The screws 61 facilitate installation and subsequent maintenance, while ensuring that the rubber strip is tightly attached to the wall to prevent it from falling off.

[0029] Furthermore, the aluminum alloy base 51 includes a base plate 53 fixed to the upper end of the wall 1 by bolts 52. A support plate 54 is provided at one end of the base plate 53 and located within the expansion joint 2. A horizontal plate 55 is provided at the lower end of the support plate 54. The side buffer part 21 is provided at the upper end of the horizontal plate 55, and one end of the support plate 54 abuts against one side of the side buffer part 21, thereby providing stable support for the side buffer part 21 and ensuring the sealing and structural stability of the expansion joint 2.

[0030] Furthermore, a limiting plate 71 is provided at one end of the base plate 53 away from the support plate 54. The outer end of the fixing part 4 abuts against the inner side of the limiting plate 71. The setting of the limiting plate 71 restricts the displacement of the outer end of the fixing part 4, preventing the rubber strip from sliding laterally due to external loads or vibrations, further enhancing the fixing effect and ensuring that the rubber strip is always in the designed position.

[0031] Furthermore, an aluminum alloy pressure strip 81 is provided in the fixing part 4. After the screw 61 passes through the aluminum alloy pressure strip 81, it is threadedly connected to the base plate 53. The aluminum alloy pressure strip 81 disperses the tightening pressure of the screw 61, avoids local pressure damage to the rubber strip, and at the same time improves the connection reliability and prevents loosening.

[0032] In this invention, a waterstop 91 is also provided inside the expansion joint 2. The waterstop 91 is located below the buffer expansion part 5. The waterstop 91 effectively prevents water from seeping into the expansion joint and avoids structural corrosion. Moreover, the cross-section of the waterstop 91 is arc-shaped, which can take into account both expansion and waterproofing requirements.

[0033] Furthermore, connecting vertical plates 92 are provided at both ends of the waterstop 91, and connecting horizontal plates 93 are provided at the upper end of the connecting vertical plates 92. The connecting horizontal plates 93 are pressed against the lower side of the aluminum alloy base 51; thereby facilitating the coordinated installation of the waterstop 91 and the rubber strip and ensuring the long-term effectiveness of the waterproof system.
