Description

Technical Field

[0001] This utility model relates to the field of building construction and is a deformation joint cover plate installation structure. Background Technology

[0002] Expansion joints are a general term encompassing expansion joints, settlement joints, and seismic joints. Buildings often deform under external forces, leading to cracking or even damage. Expansion joints are structural joints designed to address these issues. At expansion joint construction sites, to facilitate normal passage and use while fulfilling the functions of the expansion joint, a movable cover plate is usually installed. If sealing is required, a sealing structure is also necessary. Existing expansion joint cover plate structures, such as the utility model entitled "A Structure for Roof Leak-Proof Expansion Joint" published in Chinese patent literature (authorization announcement number CN210067084U, authorization announcement date February 14, 2020), disclose a three-in-one expansion joint structure suitable for expansion, settlement, and seismic resistance. Existing road expansion joint structures also adopt the above solution, but they have the following drawbacks: First, springs are prone to fatigue and deterioration after prolonged use. When the spring support force is insufficient, the cover plate is prone to jamming, loosening, or wobbling, causing the cover plate to lift and fail to return to its original position when vehicles pass by, posing a safety hazard. Second, the existing expansion joint cover structure has many components, gaps, and dead corners, making it extremely easy for dust, mud, and debris to accumulate, making cleaning difficult. Accumulated dirt can cause a sharp increase in the sliding resistance of the sliding rod, and may even cause abnormal noises during expansion and contraction. In severe cases, the cover plate may become stuck and, if forced to expand and contract, could tear the surrounding building structure. Third, maintenance costs are high. If it fails, the entire system needs to be disassembled and components replaced, which is a complex operation. Therefore, improvements to the existing expansion joint cover structure are needed. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a deformation joint cover plate installation structure that solves the technical problems of existing similar deformation joint cover plate installation structures being relatively complex, inconvenient to disassemble and maintain, having low reliability, and being prone to warping or jamming. This objective is achieved through the following technical solution.

[0004] An expansion joint cover plate installation structure is disclosed, comprising a cover plate and an installation assembly. The cover plate is fixed in a groove within the expansion joint via the installation assembly. The key structural feature is that the installation assembly includes angle steel and an L-shaped bracket. Grooves adapted to the angle steel are provided on both sides of the expansion joint. Anchor bars are integrated into the angle steel and pre-embedded in the structure within the grooves. The base plate of at least one angle steel extends horizontally into the expansion joint, forming a cover plate groove between the two angle steels. The cover plate includes at least one movable cover plate. At least one side of the bottom of the movable cover plate is fixed with an L-shaped bracket that engages with the angle steel base plate extending into the expansion joint. A vertical and horizontal clearance exists between the L-shaped bracket and the angle steel base plate after engagement, preventing the movable cover plate from easily detaching from the cover plate groove. This structure effectively prevents the cover plate from easily detaching from the cover plate groove using the L-shaped bracket and adapts to the expansion and contraction deformation at the expansion joint using the clearance. The structure is simple, easy to assemble and use, and highly efficient.

[0005] The angle steel on both sides of the expansion joint is symmetrically distributed, and each angle steel is divided into long and short sections. The base plate of the long angle steel extends into the expansion joint, while the base plate of the short angle steel does not extend into the expansion joint. The cover plate includes a fixed cover plate and a row of movable cover plates. The length of both the fixed and movable cover plates is less than or equal to the length of the short angle steel section. Each movable cover plate has an L-shaped bracket on both sides of its bottom. Each movable cover plate is inserted into the cover plate groove corresponding to the short angle steel section and slides in sequentially to engage with the base plate of the long angle steel section on both sides. The fixed cover plate is placed directly in the remaining cover plate grooves in the expansion joint, and the fixed cover plate provides resistance to the sliding direction of the remaining movable cover plates in the expansion joint. This structure is a specific implementation scheme. After the movable cover plates are slid in, they are limited by the fixed cover plates. The assembly and use are convenient and reliable, and if the movable cover plates are damaged, they can be easily replaced.

[0006] The base plate of the angle steel on one side of the expansion joint extends into the expansion joint, while the angle steel on the other side is divided into a long section and a short section. The base plate of the long section extends into the expansion joint, while the base plate of the short section does not. The cover plate includes a fixed cover plate and a row of movable cover plates. The length of both the fixed and movable cover plates is less than or equal to the length of the short section of the angle steel. Each movable cover plate has an L-shaped bracket on both sides of its bottom. Each movable cover plate is inserted into the cover plate groove corresponding to the short section of the angle steel and slides in sequentially to engage with the base plates of the angle steel on both sides. The fixed cover plate is placed directly in the remaining cover plate grooves within the expansion joint, and the fixed cover plate provides resistance to the sliding direction of the remaining movable cover plates in the expansion joint. This structure is a specific implementation scheme, which also allows the movable cover plates to be slid in and then limited by the fixed cover plates. It is convenient, efficient, and reliable to assemble, disassemble, and use. Furthermore, the fixed cover plate, through the L-shaped bracket and the angle steel base plate, provides even higher reliability in limiting the movement.

[0007] The angle steels on both sides of the expansion joint are symmetrically distributed, and the base plates of both angle steels extend into the expansion joint. The base plates extending into the expansion joint have evenly spaced openings along their length to accommodate the L-shaped brackets. The cover plate includes a fixed cover plate and at least one movable cover plate. The bottom sides of the movable cover plate have L-shaped brackets corresponding to the openings on the base plates of the angle steels on both sides. When the movable cover plate is placed into the cover plate slot, the hooks of the L-shaped brackets pass through the corresponding openings and enter below the base plates of the angle steels. When the movable cover plate is pushed to slide into place along the length of the expansion joint, the L-shaped brackets on both sides of the movable cover plate and the base plates of the angle steels on both sides form a mating fit. The remaining cover plate slots in the expansion joint directly accommodate the fixed cover plate, which provides resistance and limits the sliding direction of the remaining movable cover plates in the expansion joint. This structure, as a specific implementation scheme, effectively reduces the number of movable cover plates required, making installation more convenient and efficient when the expansion joint is long.

[0008] The fixed cover plate and the movable cover plate are each fixed with a magnetic block on one and / or both sides of their bottom, and are fixed to the corresponding angle steel base plate by magnetic attraction. Through this structure, the magnetic attraction between the cover plate and the angle steel improves the reliability of the connection between the cover plate and the angle steel. The cover plate is not easy to tilt, and even if the cover plate tilts, it can be quickly attracted and reset, making it more reliable and stable in use.

[0009] One side of the angle steel base plate extends into the expansion joint, while the other side does not. One bottom side of the cover plate has an L-shaped bracket that engages with the angle steel base plate extending into the expansion joint, and the other bottom side has a magnetic block that attracts and fixes to the other angle steel base plate. This structure, as a specific implementation, allows the cover plate to be limited on one side by the L-shaped bracket and fixed to the angle steel on the other side by magnetic attraction, making installation convenient and use reliable.

[0010] One side of the expansion joint's angle steel base plate extends into the expansion joint, while the other side's angle steel base plate does not extend into the expansion joint and has a connecting hole. One side of the cover plate has an L-shaped bracket at its bottom that fits into the angle steel base plate extending into the expansion joint. The other side of the cover plate has bolt holes aligned with the connecting hole. The cover plate is connected and fixed to the angle steel base plate and the structure using anchor bolts. This structure is a specific implementation scheme; one end of the cover plate is fixed with anchor bolts, resulting in high stability.

[0011] The bottom of the expansion joint is provided with a drainage channel frame that forms a fixed connection with the structures below the angle steel on both sides. This structure enables the drainage of accumulated water at the expansion joint.

[0012] This utility model has a simple overall structure, is easy to disassemble and maintain, saves time and effort, and has strong structural stability. The cover plate is not easily deformed or warped, making it safe, reliable, and long-lasting. It is suitable for use as a cover plate installation structure for various expansion joints, or as an improvement on similar expansion joint cover plate installation structures.

[0022] The present invention will now be further described with reference to the accompanying drawings.

[0023] like Figure 1 As shown, the expansion joint cover plate installation structure includes a cover plate 1 and an installation assembly. The cover plate is fixed in the groove where the expansion joint 301 is located by the installation assembly. The installation assembly includes an angle steel 2 and an L-shaped angle bracket 101. Grooves adapted to the angle steel are provided on both sides of the expansion joint. Anchor bars 201 are integrated into the angle steel and the structure 3 is fixed in the groove by pre-embedding the anchor bars.

[0024] like Figures 1-4The illustration shows Example 1. The angle steel 2 on both sides of the expansion joint 301 is configured such that the base plate of one side extends into the expansion joint, while the other side is divided into a long section 204 and a short section 203. The base plate of the long section 201 extends into the expansion joint, while the base plate of the short section does not. Alternatively, the angle steels on both sides are symmetrically distributed, each divided into a long section and a short section, with the base plate of the long section extending into the expansion joint and the base plate of the short section not extending into the expansion joint. A cover plate groove is formed between the two angle steels to install the cover plate 1, and the groove spacing is greater than the width of the cover plate. The cover plate includes a fixed cover plate 103 or a row of movable cover plates 102. The length of both the fixed and movable cover plates is less than or equal to the length of the short section of angle steel. Both sides of the bottom of the movable cover plate are welded with L-shaped brackets 101 that engage with the ends of the angle steel base plate 201 extending into the expansion joint. After engagement, the movable cover plate is vertically and horizontally limited relative to the angle steel base plate; that is, after the L-shaped brackets engage with the ends of the angle steel base plate, there are vertical and horizontal movement gaps that restrict the movable cover plate from disengaging from the cover plate groove. The bottom of the fixed cover plate is configured with an L-shaped bracket welded on one side to engage with the base plate of one side of the angle steel, and a magnetic block on the other side to attract and fix the base plate of the other side of the angle steel. This fixed cover plate is placed directly in the remaining cover plate groove within the expansion joint, and the fixed cover plate counteracts the sliding direction of the remaining movable cover plates in the expansion joint.

[0025] like Figure 5 , Figure 6 The following is an example of Embodiment 2. In this embodiment, the base plates 201 of the angle steels 2 on both sides of the expansion joint 301 extend into the expansion joint, and the base plates of the angle steels extending into the expansion joint are evenly spaced along the length direction with openings 205 for L-shaped brackets 101 to pass through. The cover plate includes a fixed cover plate 103 and a movable cover plate 102. The bottom sides of the movable cover plate are provided with L-shaped brackets 101 corresponding to the openings at the base plates of the angle steels on both sides; when the movable cover plate is placed into the cover plate groove, the hooks of the L-shaped brackets pass through the corresponding openings and enter below the base plates of the angle steels; when the movable cover plate is pushed to slide into place along the length direction of the expansion joint, the L-shaped brackets on both sides of the movable cover plate and the base plates of the angle steels form the same interlocking fit as in Embodiment 1. The bottom sides of the fixed cover plate are provided with magnetic blocks that are attracted and fixed to the corresponding base plates of the angle steels. The fixed cover plate bracket is placed in the remaining cover plate groove in the expansion joint, and the fixed cover plate provides a restraining limit to the sliding direction of the movable cover plate in the expansion joint.

[0026] In the above embodiments one and two, both sides of the fixed cover plate 103 and the movable cover plate 102 are provided with magnetic blocks 5 that are attracted and fixed to the bottom plate 201 of the corresponding side angle steel 2, thereby improving the firmness and reliability of the connection.

[0027] like Figure 7The following is an example of embodiment three. The angle steel 2 base plate 201 on one side of the above-mentioned expansion joint 301 extends into the expansion joint, while the angle steel base plate on the other side does not extend into the expansion joint; an L-shaped corner bracket 101 is provided on one side of the bottom of the cover plate to fit into the angle steel base plate on the side extending into the expansion joint, and a magnetic block 5 is fixedly provided on the bottom of the other side to attract and fix the other angle steel base plate.

[0028] like Figure 8 The following is an example of embodiment four. The angle steel 2 base plate 201 on one side of the aforementioned expansion joint 301 extends into the expansion joint, while the other side of the angle steel base plate has a connecting hole 206. The cover plate has an L-shaped bracket 101 on only one side of its bottom, and bolt holes aligned with the connecting hole on the other side. The cover plate is installed as follows: First, one side of the L-shaped bracket is inserted into the expansion joint and fitted into the end of the corresponding angle steel base plate. The cover plate is then adjusted so that the bolt holes on the other side align with the connecting holes of the corresponding angle steel base plate. Finally, anchor bolts 6 are passed through the bolt holes and connecting holes and then connected and fixed to the structure 3 on the side where the angle steel is located, thus completing the installation of the cover plate.

[0029] In the above embodiment, the bottom of the expansion joint 301 is provided with a flow guide frame 4 that forms a fixed structure with the structure 3 below the angle steel 2 on both sides, so as to facilitate the drainage of accumulated water.

[0030] The above description is intended to illustrate the technical means of this utility model and is not intended to limit the technical scope of this utility model. Any obvious improvements or substitutions made to this utility model by those skilled in the art based on existing common knowledge also fall within the protection scope of the claims of this utility model.
