Description

Technical Field

[0001] The present application relates to the technical field of prefabricated assembly of beams and slabs, and in particular to a prefabricated assembly reinforcement connector for beams and slabs. Background Art

[0002] In modern bridge construction and existing bridge reinforcement and renovation projects, prefabricated beam-slab assembly technology is widely used due to its advantages such as high efficiency and controlled quality. With the continuous increase in traffic volume and the increase in service life, higher requirements are placed on the safety and durability of bridge structures. Traditional beam-slab connection methods have gradually exposed some problems during long-term use. For example, when using ordinary wet joint connections, although the integrity of the structure can be guaranteed to a certain extent, the quality of the interface between the new and old concrete cannot be fully guaranteed. Under the action of repeated vehicle loads, cracks are prone to expand and the stiffness of the connection parts is reduced. At the same time, in the reinforcement projects of some old bridges, the original connection method may not be able to meet the new load requirements.

[0003] The existing precast beam hydraulic integral self-propelled formwork device includes a pedestal and modular side formworks arranged on both sides of the pedestal. The modular side formworks are respectively provided with external supports, and the lower ends of the external supports are provided with horizontal cranes. Tracks are respectively provided on both sides of the pedestal, and the horizontal cranes are respectively provided on the tracks. The horizontal cranes are provided with horizontal hydraulic cylinders and vertical hydraulic cylinders, and the horizontal hydraulic cylinders are hinged to the horizontal cranes. The lower end of the modular side formwork is provided with a bottom longitudinal beam, and the upper end is provided with an upper longitudinal beam. The inner walls of the external supports are respectively provided with slides, one end of the upper longitudinal beam is provided in the slide, and the other end is connected to the modular side formwork. The hydraulic rod of the horizontal hydraulic cylinder is hinged to the bottom longitudinal beam, and the hydraulic rod of the vertical hydraulic cylinder is connected to the upper longitudinal beam.

[0004] However, some existing connection devices and reinforcement measures often have problems such as complex installation, high cost, and limited adaptability. Moreover, the existing devices cannot be quickly positioned and installed during assembly and require constant adjustment to fix them, which is inefficient and affects the construction progress, so there is room for improvement.

[0028] The following is combined with Figure 1-4 This application is described in further detail.

[0029] The embodiment of the present application discloses a beam-slab prefabricated assembly reinforcement connector. Figure 1 A beam-slab prefabricated assembly reinforcement connector includes a main beam-slab body 1, a secondary beam-slab body 2 and a connecting mechanism 3. The inner wall connection between the main beam-slab body 1 and the secondary beam-slab body 2 is provided with a connecting mechanism 3 for connection and fixation.

[0030] Reference Figure 1 and Figure 2 The connection mechanism 3 includes a front connector 31, a rear connector 32, and a connection plate 33. The inner side of the front connector 31 is threadedly fixed to the front bottom ends of the main beam body 1 and the auxiliary beam body 2, respectively. The inner side of the rear connector 32 is threadedly fixed to the rear bottom ends of the main beam body 1 and the auxiliary beam body 2, respectively. The front connector 31 and the rear connector 32 are welded together with six sets of connection plates 33. The front connector 31 and the rear connector 32 have the same structure and are installed as mirror images.

[0031] Six groups of connecting plates 33 are fixed to the rear side of the front connecting member 31 and welded to the front end of the rear connecting member 32. Two groups of cross plates 34 are welded to the bottom ends of the six groups of connecting plates 33. Through this design, the connecting plates 33 and the two groups of cross plates on the bottom side can be better used to support the main beam plate body 1 and the auxiliary beam plate body 2, thereby improving the stability of the connection between the main beam plate body 1 and the auxiliary beam plate body 2.

[0032] Reference Figure 3 The front connecting member 31 includes two groups of clamping members 311 and a rack plate 314. The front outer walls of the two groups of clamping members 311 are respectively fixed with a locking box 312 and a driving box 313. The right end of the locking box 312 is provided with two groups of rack plates 314 which are inserted to the left and extend to the outside of the left end of the driving box 313.

[0033] Two groups of front connecting members 31 and rear connecting members 32 with the same structure limit the connection between the main beam plate body 1 and the auxiliary beam plate body 2, which is convenient for positioning and connection. The front connecting members 31 and the rear connecting members 32 are provided with six groups of connecting plates 33 and two groups of cross plates 34 for connection and fixation, which can improve the connection stability and increase the service life. The driving box 313 and the locking box 312 can be connected. This design structure is simple and easy to connect, and the positioning is simple without the need for multiple adjustments.

[0034] Reference Figure 3 The clamping member 311 includes a base plate 3111 and a rotating plate 3114. A square groove 3112 is provided at the front end of the base plate 3111. Fixed columns 3113 are fixed on both sides of the inner wall of the square groove 3112. The bottom end of the rotating plate 3114 is inserted into the fixed columns 3113. Two groups of extension plates 3115 are fixed on both sides of the base plate 3111. Extension plates 3115 are fixed on both sides of the top of the rotating plate 3114. Bolts 3116 are inserted into the central threads of the six groups of extension plates 3115.

[0035] This design allows the main beam plate body and the auxiliary beam plate body to be wrapped and fixed, facilitating subsequent positioning and connection, saving time and improving stability.

[0036] Reference Figure 4 The locking box 312 has two sets of upper and lower through-grooves 3121 defined within it. An inner groove 3122 is defined at the center front of each set of through-grooves 3121. Rotating shafts 3123 are inserted into the upper and lower ends of each set of inner grooves 3122. The locking box 312 is fixed to the top front of the right clamping member 311, while the driving box 313 is fixed to the top front of the left clamping member 311. The locking box 312 and the driving box 313 are arranged parallel to each other. A connecting rod 3131 extends through the driving box 313, connecting the two sets of rotating shafts 3123. A rotating disc 3132 is fixed to the top of the connecting rod 3131. Limiting blocks 3141 are fixed to the right ends of the two rack plates 314. The racks of both rack plates 314 engage with gears 3124.

[0037] After the rack plate 314 passes through the inner groove 3122 inside the drive box 313, it only needs to rotate the rotating disk 3132 at the top to drive the rotating shaft 3123 at the bottom to rotate. The rotation of the rotating shaft 3123 synchronously drives the two sets of gears 3124 to rotate and engage the rack plate 314 to move, thereby conveniently connecting the two sets of clamping parts 311 with the rack plate 314 to improve the tightness of the connection between the main beam plate body 1 and the auxiliary beam plate body 2. This design makes it easy to insert the rack plate. The rotating disk can drive the rotating shaft to rotate, thereby moving the rack plate to achieve the connection effect, which is convenient for installation and saves time.

[0038] The principle of the prefabricated beam-slab reinforcement connector of the present embodiment is as follows: when the main beam slab body 1 and the auxiliary beam slab body 2 need to be spliced, the rear top ends of the four sets of clamping members 311 are first affixed to the front and rear sides of the bottom ends of the connection between the main beam slab body 1 and the auxiliary beam slab body 2. Then, the rotating plates 3114 are rotated respectively to affix to the side inclined surfaces of the main beam slab body 1 and the auxiliary beam slab body 2 under the limit of the fixed columns 3113 inserted at the bottom ends. Then, bolts 3116 are threadedly fixed to the interior of the main beam slab body 1 and the auxiliary beam slab body 2 through the fixed extension plates 3115. Subsequently, the front and rear sets of clamping members 311 are connected and fixed using six sets of connecting plates 33.

[0039] Two sets of transverse plates 34 are installed at the bottom ends of the six sets of connecting plates 33 for transverse welding and reinforcement. The rack plate 314 is then inserted leftward through the two sets of through slots 3121 on the right side of the locking box 312. As the rack plate 314 moves, it engages with a gear 3124 located within a recess 3122 within the locking box 312, causing it to rotate. Once the rack plate 314 extends from the locking box 312 into the through slot 3121 within the drive box 313, the left end of the rack plate 314 contacts the gear 3124 and is then rotated by the rotating disc 3132 at the top, thereby driving the connected gear 3124 to rotate, engaging the rack plate 314 and moving it leftward, completing the connection and assembly.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
