Description

Technical Field

[0001] This utility model relates to the field of bridge deck hoisting technology, and in particular to a slot-type bridge deck fixing device. Background Technology

[0002] In the field of bridge construction and maintenance, the connection and fixation between the bridge deck and the distribution beams is a core element in ensuring the load-bearing capacity and traffic safety of the bridge structure. Especially in modern intelligent transportation bridges integrating intelligent cabin systems, the stability of this connection structure directly affects the reliable operation of the intelligent cabin's functions. As a core unit of the intelligent transportation system, the intelligent cabin often integrates modules such as load monitoring, vibration sensing, and data transmission. It relies on the long-term stability of the main bridge structure to achieve accurate collection and analysis of real-time stress on the bridge deck and changes in traffic loads, providing a reliable basis for bridge safety early warning.

[0003] However, the existing connection methods between bridge decks and distribution beams generally suffer from key problems such as insufficient pre-positioning accuracy and weak resistance to vibration and loosening, which increases the frequency and cost of later maintenance. Utility Model Content

[0004] This invention provides a slot-type bridge deck fixing device, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A slot-type bridge deck fixing device includes: The distribution beam has a slot on one side; The bridge deck has a locking block on one side, which is embedded in a slot to allocate the pre-position of the beam and the bridge deck. Rubber sheet, installed between the distribution beam and the bridge deck; Connection mechanism, used to connect the distribution beam to the bridge deck; The anti-loosening mechanism is installed on the connecting mechanism.

[0006] Furthermore, the connecting mechanism includes: At least two threaded rods are provided at equal intervals along the length of the distribution beam. The threaded rods pass through the through holes of the rubber plate and the bridge deck respectively, and are threadedly connected to the pre-set threaded holes on the distribution beam. The nut is used to connect with the threaded rod and is also used to connect the bridge deck.

[0007] Furthermore, the anti-loosening mechanism includes: Anti-loosening washers are installed between the bridge deck and the nut. The anti-loosening washers are double-layered elastic metal washers with reverse serrated patterns on the contact surfaces of the double-layered elastic metal washers. The anti-loosening pin is installed in the pin hole opened radially on the threaded rod, with both ends of the anti-loosening pin passing through the pin hole.

[0008] Furthermore, an anti-slip pad is provided between the anti-loosening washer and the bridge deck, and the anti-slip pad has a textured surface on the side facing the anti-loosening washer.

[0009] Furthermore, the rubber plate has a protrusion on the side facing the slot, which is embedded in the slot and fits tightly against the bottom of the slot.

[0010] Furthermore, the card block and the card slot are interference fit, the outer wall of the card block and the inner wall of the card slot are tightly fitted, and the top of the card block is provided with a guide slope.

[0011] Furthermore, at least two card slots are equally spaced along the length of the distribution beam, and each card slot is symmetrically arranged about the center line of the distribution beam. Each card slot is adapted to a card block.

[0012] Furthermore, the card slot has a U-shaped structure, and the inner wall of the card slot is provided with anti-slip texture, which extends along the length of the card slot.

[0013] The following technical effects can be achieved through the technical solution of this utility model: The bridge deck's locking blocks embed into the slots of the distribution beam, enabling rapid pre-positioning of the distribution beam and bridge deck. This assists in aligning the mounting holes of the connecting mechanism, improving the assembly efficiency of hoisting and fixing. The rubber plate placed between the distribution beam and bridge deck utilizes the elastic deformation of rubber to buffer vibration loads during hoisting and subsequent use, reducing rigid impacts between the distribution beam and bridge deck and protecting the structural integrity of both. The connecting mechanism, in conjunction with the pre-positioning structure, connects the distribution beam and bridge deck, ensuring that the vertical and horizontal loads borne by the bridge deck are effectively transferred to the distribution beam, avoiding connection failures caused by localized stress concentration. The anti-loosening mechanism installed on the connecting mechanism solves the problem of loosening of the threaded pair of the connecting mechanism under vibration, ensuring the connection stability of the device for long-term use and reducing subsequent maintenance costs.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0018] This application provides a slot-type bridge deck fixing device, including: Distribution beam 1 has a slot on one side; The bridge deck 2 has a locking block 3 on one side, which is embedded in a slot to allocate the pre-position of the beam 1 and the bridge deck 2. Rubber sheet 4 is installed between distribution beam 1 and bridge deck 2; Connection mechanism 5 is used to connect the distribution beam 1 and the bridge deck 2; Anti-loosening mechanism 6 is installed on connecting mechanism 5; Through the technical solution of this utility model, the locking block 3 of the bridge deck 2 is embedded into the locking groove of the distribution beam 1, realizing the rapid pre-positioning of the distribution beam 1 and the bridge deck 2, assisting in aligning the installation holes of the connecting mechanism 5, and improving the assembly efficiency of hoisting and fixing. The rubber plate 4 set between the distribution beam 1 and the bridge deck 2 uses the elastic deformation of rubber to buffer the vibration load during hoisting and subsequent use, reducing the rigid impact between the distribution beam 1 and the bridge deck 2, and protecting the structural integrity of both. The connecting mechanism 5, in conjunction with the pre-positioning structure, connects the distribution beam 1 and the bridge deck 2, ensuring that the vertical and horizontal loads borne by the bridge deck 2 are effectively transferred to the distribution beam 1, avoiding connection failure caused by local stress concentration. The anti-loosening mechanism 6 installed on the connecting mechanism 5 solves the problem of loosening of the threaded pair of the connecting mechanism 5 under vibration environment, ensuring the connection stability of the device for long-term use, and reducing the later maintenance cost.

[0019] During use, the connecting mechanism 5 includes: At least two threaded rods 51 are provided at equal intervals along the length of the distribution beam 1. The threaded rods 51 pass through the through holes of the rubber plate 4 and the bridge deck 2 respectively, and are threadedly connected to the threaded holes on the distribution beam 1. Nut 52 is connected to threaded rod 51 and is connected to bridge plate 2; Through the technical solution of this utility model, at least two threaded rods 51 are equally spaced along the length of the distribution beam 1 to avoid damage to the structure of the distribution beam 1 or the bridge deck 2 due to local load concentration. At the same time, the setting of multiple sets of threaded rods 51 can enhance the overall rigidity of the connection between the distribution beam 1 and the bridge deck 2, and ensure the structural stability after hoisting and fixing. The threaded rods 51 are threaded to ensure that the rubber plate 4 is tightly clamped between the distribution beam 1 and the bridge deck 2, ensuring the effective function of the rubber plate 4 in buffering vibration loads. The threaded engagement can also initially fix the relative positions of the three. The nut 52 is connected to the threaded rod 51 and to the bridge deck 2. By tightening the nut 52, an axial clamping force is formed on the bridge deck 2, making the bridge deck 2, the rubber plate 4 and the distribution beam 1 fit more tightly. The detachability of the threaded connection facilitates the replacement and maintenance of the rubber plate 4, the threaded rod 51 or the nut 52 in the future without damaging the main structure of the distribution beam 1 and the bridge deck 2, thus reducing maintenance costs.

[0020] In the above embodiments, the anti-loosening mechanism 6 includes: Anti-loosening washer 61 is provided between bridge plate 2 and nut 52. Anti-loosening washer 61 is a double-layered elastic metal washer. The contact surface of the double-layered elastic metal washer is provided with reverse serrated texture. The anti-loosening pin 62 is provided in the pin hole opened radially in the threaded rod 51, and both ends of the anti-loosening pin 62 pass through the pin hole; An anti-slip pad 8 is provided between the anti-loosening washer 61 and the bridge deck 2. The anti-slip pad 8 has a textured surface on the side facing the anti-loosening washer 61. Through the technical solution of this utility model, the double-layered elastic metal washer with reverse serrated texture on the contact surface continuously provides axial clamping force to the nut 52 by utilizing the elastic deformation of the double-layered metal, avoiding the attenuation of clamping force due to vibration during long-term use. The reverse serrated texture generates reverse friction force during vibration, effectively counteracting the loosening tendency of the nut 52 relative to the threaded rod 51. The anti-loosening pin 62 passes through the radial pin hole of the threaded rod 51 and extends out at both ends, directly restricting the axial rotation of the threaded rod 51 by mechanical locking, preventing relative rotation between the threaded rod 51 and the threaded hole of the distribution beam 1 and the nut 52 under vibration environment, avoiding the risk of the threaded pair of the connecting mechanism 5 disengaging. The concave and convex texture of the anti-slip washer 8 facing the anti-loosening washer 61 increases the contact friction with the anti-loosening washer 61, providing a stable support base for the anti-loosening washer 61 and preventing the anti-loosening washer 61 from sliding relative to the bridge deck 2.

[0021] During use, the rubber plate 4 has a protrusion 7 on the side facing the slot, and the protrusion 7 is embedded in the slot and fits tightly with the bottom of the slot; The technical solution of this utility model uses the protrusion 7 and the slot to position the rubber plate 4, and with the pre-positioning effect of the card block 3 of the bridge deck 2 embedded in the slot, the relative positions of the distribution beam 1, rubber plate 4 and bridge deck 2 are improved during assembly.

[0022] In the above embodiment, the card block 3 and the card slot are interference fit, the outer wall of the card block 3 is tightly fitted with the inner wall of the card slot, and the top of the card block 3 is provided with a guide slope. Through the technical solution of this utility model, the guide slope guides the card block 3 to smoothly embed into the card slot of the distribution beam 1 during the assembly of the bridge deck 2 and the distribution beam 1, reducing the difficulty of the operation of aligning the two during the hoisting process. The interference fit between the card block 3 and the card slot eliminates the assembly gap between the card block 3 and the card slot, preventing the bridge deck 2 from shifting relative to the distribution beam 1 and enhancing the stability of the structure.

[0023] As a preferred embodiment of the above embodiment, at least two card slots are provided at equal intervals along the length direction of the distribution beam 1, and each card slot is symmetrically arranged about the center line of the distribution beam 1. Each card slot is correspondingly fitted with a card block 3. The technical solution of this utility model achieves multi-point pre-positioning of the bridge deck 2 and the distribution beam 1 through the cooperation of multiple sets of slots and blocks 3, avoiding local stress concentration of the bridge deck 2 caused by single-point pre-positioning. Each slot is symmetrically arranged about the center line of the distribution beam 1, so that the force on both sides of the distribution beam 1 is balanced, preventing the distribution beam 1 from undergoing lateral bending deformation due to asymmetrical force on the pre-positioning structure, and ensuring the structural integrity of the distribution beam 1.

[0024] During use, the card slot has a U-shaped structure, and the inner wall of the card slot is provided with anti-slip texture, which extends along the length of the card slot. Through the technical solution of this utility model, the slot is designed with a U-shaped structure to facilitate the quick insertion of the card block 3 and the protrusion 7 during hoisting and assembly, reducing the difficulty of aligning the card block 3, the protrusion 7 and the slot. The anti-slip texture extended along the length direction on the inner side wall of the slot increases the contact friction between the inner wall of the slot and the outer wall of the card block 3 and the outer wall of the protrusion 7. Combined with the interference fit between the card block 3 and the slot, it effectively suppresses the sliding of the card block 3 and the protrusion 7 in the slot along the length direction or radial direction, and improves the stability of the fit.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
