[0001] The utility model relates to the technical field of steel bridge decks, in particular to a steel bridge deck convenient for connection. Background Technique

[0002] A steel trestle bridge is a special type of bridge with fast construction and good seismic performance, and can be widely applied to the construction of various roads,

[0003] railways, etc. The steel trestle bridge is mainly composed of a bridge deck, Bailey trusses, support beams, support columns, etc., and has the characteristics of light

[0004] weight, convenient construction, good seismic and wind resistance performance, and no sound vibration transmission. The deck needs to be connected to the support structure, so installation holes are arranged on the deck to connect with the support structure, so that the bearing capacity received on the deck is transmitted to the support structure,

Detailed implementation manner

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1 to 5 , the present invention provides a steel bridge panel that is convenient for connection, including two panels 1. A connecting plate 2 is connected between the two panels 1. The panels 1 and the connecting plate 2 are made of high-strength steel materials, having good compressive resistance and not being easily bent and deformed. When the two panels 1 are butted, the relative sliding between the panel 1 and the connecting plate 2 is enabled to realize the distance control between the two panels 1, which can be flexibly adjusted according to actual installation requirements and has strong applicability. The connecting plate 2 is connected with a positioning mechanism for synchronously positioning the two panels 1. The positioning mechanism includes four positioning rods 6, two cross plates 7, and a stud 8. The two ends of the cross plate 7 are connected to the positioning rods 6. The stud 8 is used to drive the two cross plates 7 to approach or move away from each other. Positioning grooves 5 matching the ends of the positioning rods 6 are provided at both ends of the panel 1. The stud 8 is connected with a driving mechanism for driving the rotation of the stud 8.

[0026] When the two panels 1 are connected, by rotating the rotating head 4 to drive the rotation of the stud 8, the two cross plates 7 are moved away from each other. The cross plates 7 synchronously drive the two positioning rods 6 to move until the ends of the positioning rods 6 are connected to the corresponding positioning grooves 5, and then the rotation of the rotating head 4 is stopped, thereby realizing the fixed connection between the panel 1 and the connecting plate 2, improving the stability of the connection between the two panels 1, and the operation is simple and convenient.

[0027] The positioning mechanism further includes two sliding blocks 10. The sliding blocks 10 are used for guiding the cross plates 7. Two sliding grooves 9 are provided inside the connecting plate 2. The sliding blocks 10 are slidably connected to the corresponding sliding grooves 9, and the sliding blocks 10 are fixedly connected to the cross plates 7. When the cross plates 7 move, the sliding blocks 10 slide in the corresponding sliding grooves 9, playing a good guiding role for the cross plates 7 and improving the stability of the movement of the cross plates 7.

[0028] The stud 8 is threadedly connected to the two cross plates 7, and the end of the stud 8 is rotatably connected to the connecting plate 2, improving the stability of the rotation of the stud 8.

[0029] Both ends of the cross plate 7 are slidably connected to the connecting plate 2, and the internal thread directions of the two cross plates 7 are opposite, enabling the two cross plates 7 to approach or move away from each other. When the two cross plates 7 move away from each other, the positioning rod 6 is connected to the positioning groove 5 to realize the docking of the two panels 1; when the two cross plates 7 approach each other, the positioning rod 6 is separated from the positioning groove 5 to realize the synchronous loosening of the two panels 1.

[0030] Both ends of the panel 1 are provided with connection grooves 3 that match the connecting plate 2. The connection grooves 3 provide a good guiding purpose for the panel 1 and improve the stability of the movement of the panel 1. The connection grooves 3 communicate with the positioning grooves 5. A plurality of positioning grooves 5 are provided in a single connection groove 3, and the spacing between adjacent positioning grooves 5 is equal.

[0031] The driving mechanism includes a rotating head 4, a guiding groove 12, a guiding block 13, and a spring 14. The end of the stud 8 is connected to the guiding block 13. The guiding block 13 is slidably connected to the guiding groove 12. The guiding groove 12 is provided in the rotating head 4. The spring 14 is used to drive the rotating head 4 to move in the direction close to the connecting plate 2. When rotating the rotating head 4, first pull the rotating head 4 to separate it from the locking groove 11 to realize the loosening of the rotating head 4. At this time, the guiding block 13 slides in the guiding groove 12, and the spring 14 is in a stretched state. Then, rotating the rotating head 4 can drive the guiding block 13 to rotate, and the guiding block 13 synchronously drives the stud 8 to rotate; when stopping rotating the rotating head 4, directly release the rotating head 4, and the stretched spring 14 drives the rotating head 4 to return to its position, so that the rotating head 4 is connected to the locking groove 11 to realize the positioning of the rotating head 4, avoiding loosening of the rotating head 4 caused by external vibration and affecting the stability of the connection between the two panels 1, which is safe and reliable.

[0032] The cross-sections of the guiding block 13 and the guiding groove 12 are square structures, and the rotation of the rotating head 4 can synchronously drive the rotation of the guiding block 13.

[0033] The side of the connecting plate 2 is provided with a locking groove 11 that matches the rotating head 4. The cross-section of the locking groove 11 is a regular polygon structure. When the rotating head 4 is connected to the locking groove 11, the locking and positioning of the rotating head 4 are realized.

[0034] The spring 14 is located in the guiding groove 12, and both ends of the spring 14 are connected to the guiding block 13 and the rotating head 4.

[0035] Working principle: When two panels 1 are connected, first adjust the distance between the two panels 1 to meet the actual installation requirements. Then rotate the rotating head 4 to drive the guide block 13 to rotate. The guide block 13 drives the stud 8 to rotate synchronously, so that the two cross plates 7 move away from each other. The cross plates 7 drive the two positioning rods 6 to move synchronously, so that the ends of the positioning rods 6 are connected to the corresponding positioning grooves 5, realizing the docking of the panel 1 and the connecting plate 2, improving the stability of the connection between the two panels 1. Finally, loosen the rotating head 4, and the stretched spring 14 drives the rotating head 4 to return to its original position, so that the rotating head 4 is connected to the locking groove 11, realizing the positioning and fixing of the rotating head 4, avoiding loosening of the rotating head 4 caused by external vibration and affecting the stability of the connection between the two panels 1, and the use is safe and reliable. When the two panels 1 need to be separated, rotate the rotating head 4 to drive the stud 8 to rotate back, so that the two cross plates 7 approach each other. The cross plates 7 drive the positioning rods 6 to move back, so that the positioning rods 6 are separated from the positioning grooves 5, realizing the loosening of the panel 1 and facilitating the separation.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
