Description

Technical Field

[0001] This utility model belongs to the technical field of expansion joint cover plates, specifically relating to an internal snap-on anti-loosening expansion joint cover plate for floors. The cover plate achieves installation and anti-loosening functions through a self-locking connection between the upper cover plate and the lower internal snap-on plate. Background Technology

[0002] In existing technologies for building floor expansion joint covers, some use self-tapping screws to anchor the upper cover to the lower structure, while others use fasteners to connect the upper and lower covers. However, in actual use, due to the effects of climatic expansion and contraction, these expansion joint covers may experience problems such as arching deformation, loosening of cover bolts, and cover movement or detachment. Furthermore, the installed covers are difficult to repair and disassemble, and their firmness and durability are not ideal, requiring frequent maintenance, which increases maintenance costs and workload. Summary of the Invention

[0003] To effectively overcome the problems of arching deformation, loose screws, and detachment caused by climatic expansion and contraction of existing floor expansion joint covers, and to solve the inconvenience of maintenance and disassembly, this utility model provides an internal snap-on anti-loosening expansion joint cover for floors. This cover has a simple and convenient installation process, a self-locking anti-loosening function, is easy to maintain and disassemble after installation, and has horizontal and longitudinal / lateral mobility. It meets the requirements of durability, weather resistance, and robustness, while significantly improving the installation efficiency of expansion joint covers.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: the upper cover plate of the expansion joint and the lower inner clamping plate are mutually self-locking connected, and the inner clamping plate is installed on the floor by means of expansion screws and the floor slab structure on both sides of the expansion joint.

[0005] Furthermore, the expansion joint cover is integrally formed from the cover flange, retaining strip, anti-slip groove, upper cover panel, and cover purlin. The surface of the upper cover panel is provided with concave arc anti-slip groove to increase friction and prevent pedestrians from slipping; the bottom of the cover is provided with cover purlin to enhance the structural strength of the cover.

[0006] Furthermore, the inner card plate is integrally formed from an inner card base plate, an inner card strip, and bolt holes.

[0007] Furthermore, the expansion bolts are anchored to the floor slab structure on both sides of the expansion joint by drilling.

[0008] Furthermore, the expansion joint cover plate is self-lockingly connected to the inner clamping plate installed below via its locking strips, achieving an anti-loosening function. Additionally, the two locking strips can move relative to each other longitudinally, facilitating expansion and contraction adjustments due to temperature changes. The upper and lower locking strips are also detachable for easy maintenance.

[0009] Furthermore, the inner base plate has an elliptical bolt hole in the middle, which allows the expansion bolt to move horizontally relative to the floor structure within the bolt hole of the inner base plate, thereby realizing the function of an expansion joint and effectively coping with the expansion and contraction deformation of the floor caused by temperature changes.

[0010] Furthermore, the upper and lower plates of the floor expansion joint cover do not require adhesive bonding or screw connection. The expansion joint cover is detachable, making the installation process convenient and quick, and enabling the installation of the floor expansion joint cover to be completed rapidly.

[0011] The beneficial effects of this utility model are as follows: the installation process of the internal snap-on anti-loosening expansion joint cover plate is simple, the internal snap-on structure has a reliable anti-loosening function, and it is convenient for maintenance and disassembly, while also speeding up the installation of the expansion joint cover plate. In addition, the cover plate has a simple structure, low cost, and can effectively cope with the effects of climatic expansion and contraction, thus improving the performance and service life of the floor expansion joint cover plate.

For example, "connection" can be a self-locking connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0023] In this application, unless otherwise expressly specified and limited, the first feature being "on" or "below" the second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0024] like Figure 1 As shown, the floor and ground inner clip anti-loosening expansion joint cover of this utility model is installed on the floor and ground (4) by means of expansion screws (3) and the floor structure (5). The expansion joint cover (1) and the inner clip (2) are self-clamped.

[0025] like Figure 2 , 4As shown, the expansion joint cover of this utility model includes a cover flange (101), a retaining strip (102), an anti-slip groove (103), an upper cover panel (104), and a cover purlin (105). The concave anti-slip groove (103) on the surface of the upper cover panel (104) can effectively increase friction and prevent pedestrians from slipping; the cover purlin (105) at the bottom of the cover can enhance the structural strength of the cover. The cover retaining strip (102) is self-lockingly connected to the lower inner retaining plate (2), and the cover flange (101) overlaps with the floor (4) to ensure the stability of the cover installation.

[0026] like Figure 3 , 5 As shown, the inner clamping plate of this utility model includes an inner clamping base plate (201), an inner clamping strip (202), and bolt holes (203). An elliptical bolt hole (203) is opened in the middle of the inner clamping base plate (201), and the inner clamping strip (202) of the inner clamping plate is mutually self-clamped with the clamping strip (102) of the expansion joint cover plate.

[0027] like Figure 1 , 3 As shown, the expansion bolts (3) are anchored to the floor structure (5) on both sides of the expansion joint (6) by drilling, and the inner clamping plate (2) is firmly anchored to the floor structure (5) by the expansion bolts (3).

[0028] like Figure 1 , 4 As shown in Figure 5, the locking strip (102) of the expansion joint cover plate has an inward arc-shaped locking platform, and the locking strip (202) of the inner locking plate has an outward arc-shaped locking platform. The locking strip (102) of the cover plate and the inner locking strip (202) of the inner locking plate are mutually self-locking connected through the arc-shaped locking platforms to achieve the anti-loosening function. In addition, the two locking strips can move relative to each other in the longitudinal direction to adapt to the expansion and contraction of the floor. The elliptical bolt hole (203) in the middle of the inner locking base plate (201) allows the expansion bolt (3) to move horizontally relative to the bolt hole (203) of the inner locking plate along with the floor structure (5), thereby meeting the needs of the expansion joint to move forward, backward, left, and right.

[0029] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing, those skilled in the art should understand that modifications can still be made to the foregoing technical solutions, or equivalent substitutions can be made to some or all of the technical features.
