Description

Technical Field

[0001] The invention belongs to the technical field of construction engineering, and specifically refers to a reinforcement device for cantilever construction engineering. Background Art

[0002] Cantilever design is very common in building and structural design. By suspending a part of the structure outwards without relying on the support below and only bearing the load through the cantilever structure, this design method not only creates unique building forms and spatial effects, but also poses higher requirements for structural design and construction technology. During the actual construction process, attention needs to be paid to the reinforcement work of the cantilever structure.

[0003] The existing reinforcement methods for cantilever structures mainly include steel bonding reinforcement, carbon fiber reinforcement, and additional member reinforcement. Among them, the method of adding additional members is relatively common. For example, reinforced concrete columns or diagonal braces are added at the end of the cantilever structure. However, the reinforced concrete columns and diagonal braces together with the cantilever platform form a rigid structure, making it difficult to achieve adjustability during the construction stage and coordinated deformation during the use stage. At the same time, when reinforcing complex-shaped cantilever structures, the adaptability of standardized components to the special-shaped structure surface is poor, resulting in difficult control of construction accuracy. The existing reinforcement of cantilever structures can also be achieved by setting cables above the cantilever structure to share the load at the end of the cantilever structure. However, the cables set above the cantilever structure occupy the space above the cantilever structure, affecting the aesthetics of the cantilever structure.

[0004] Therefore, a reinforcement device for cantilever construction engineering is proposed to solve the problems existing in the existing reinforcement methods for cantilever structures. Summary of the Invention

[0005] To solve the above-mentioned existing problems, the invention provides a reinforcement device for cantilever construction engineering. A flexible adjustable cable adjustment component and a rod adjustment component are fixedly arranged on the support pier. By the flexible sliding of the first slider and the second slider in the first chute and the second chute respectively, a plurality of rotation connection blocks and support rods are adjusted to open or close, thereby changing the positions of the stay cables and the support rods to adapt to cantilever platforms of different shapes. The stay cables are connected to the ends of the support rods to form a stable cable structure. Construction workers uniformly fix hanging rods at the ends of the lower wall of the cantilever platform according to the shape of the cantilever platform, and connect the support rods with the hanging rods through the lifting cables. The lifting cables generate an upward pulling force on the hanging rods, so that the hanging rods apply an upward force to the ends of the cantilever platform, effectively sharing the load at the ends of the cantilever platform, and at the same time ensuring the integrity of the space above the cantilever platform, avoiding the space being occupied by the cable structure set above the cantilever platform and affecting the aesthetics.

[0015] Furthermore, the stay cable and the lifting cable adopt epoxy-coated high-strength steel wire cables.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] (1) A cable adjustment assembly and a rod adjustment assembly that can be flexibly adjusted are fixedly arranged on the support pier. By the flexible sliding of the first slider and the second slider in the first sliding groove and the second sliding groove respectively, a plurality of rotary connection blocks and support rods are adjusted to open or close, so as to change the positions of the stay cable and the support rods to adapt to cantilever platforms of different shapes. The stay cable is connected to the end of the support rod to form a stable cable structure;

[0018] (2) According to the shape of the cantilever platform, the construction workers evenly and fixedly install the hanging rods at the end of the lower wall of the cantilever platform, and connect the support rod with the hanging rod through the lifting steel cable. The support rod bears pressure under the pulling of the inclined pulling steel cable and the lifting steel cable. The lifting steel cable generates an upward pulling force on the hanging rod, so that the hanging rod applies an upward force to the end of the cantilever platform, effectively sharing the load at the end of the cantilever platform, and at the same time ensuring the integrity of the space above the cantilever platform, avoiding the occupation of the space caused by the cable structure arranged above the cantilever platform and affecting the aesthetics;

[0019] (3) The construction workers can rotate the turning handle to make the adjusting worm rotate. The adjusting worm drives the adjusting worm gear to rotate, and the adjusting worm gear drives the inclined pulling roller to rotate, so that the inclined pulling steel cable is wound back onto the inclined pulling roller or released from the inclined pulling roller. The length of the inclined pulling steel cable between the inclined pulling roller and the upper connecting shaft changes. When the inclined pulling steel cable is wound back onto the inclined pulling roller, the upper connecting shaft moves upward under the pulling force of the inclined pulling steel cable, the support rod rotates upward in a pitching motion, the upper connecting shaft pulls the lower connecting shaft to offset upward through the lifting steel cable, so that the hanging rod drives the end of the cantilever platform to offset upward, further improving the bending deformation problem caused by the self-weight of the end of the cantilever platform, increasing the structural stability. The winding amount of the inclined pulling steel cable can be adjusted according to the actual situation to meet the construction requirements of different cantilever structures, realizing the adjustability during the construction stage and the coordinated deformation during the use stage. At the same time, by setting the inclined pulling steel cable and the lifting steel cable, the cantilever reinforcement assembly forms a flexible structure, which has stronger seismic resistance and environmental adaptability compared with the traditional rigid structure;

[0020] (4) The first adjusting block and the second adjusting block can slide in the upper adjusting groove, and the third adjusting block can slide in the lower adjusting groove. When the inclined pulling steel cable pulls the upper connecting shaft, the first adjusting block, the second adjusting block and the third adjusting block can adaptively slide in the upper adjusting groove and the lower adjusting groove respectively according to the change of the relative position between the upper connecting shaft and the lower connecting shaft, so that the forces on the inclined pulling steel cable and the lifting steel cable are more reasonable.

The clamping blocks 35 are respectively arranged in the upper clamping grooves 32 and the lower clamping grooves 41 in a sliding fit manner.

[0040] Working principle and working process:

[0041] According to the pre-designed plan, the construction workers first tie the first anchor bars 8 provided on the first connecting plate 7 and the second anchor bars 22 provided on the second connecting plate 21 to the internal steel bars of the support pier 4 respectively. When pouring the support pier 4, the first connecting plate 7 and the second connecting plate 21 can be firmly connected to the support pier 4, so that the steel cable adjusting assembly 6 and the rod adjusting assembly 20 are firmly fixed on the support pier 4. After the installation is completed, according to the shape of the cantilever platform 3, the construction workers uniformly and fixedly arrange the lower suspension rods 36 at the ends of the lower wall of the cantilever platform 3. During the specific construction, the third anchor bars 38 provided on the third connecting plate 37 can be tied to the internal steel bars of the cantilever platform 3. When pouring the cantilever platform 3, the third connecting plate 37 can be firmly connected to the cantilever platform 3, so that the lower suspension rods 36 are firmly fixed on the lower wall of the cantilever platform 3.

[0042] The construction workers unscrew the first fixing nut 14 and the second fixing nut 28 from the first sliding screw 13 and the second sliding screw 27 respectively, so that the first fixing nut 14 and the second fixing nut 28 are separated from the contact with the upper and lower walls of the first support block 9 and the second support block 23. At this time, the first sliding screw 13 and the second sliding screw 27 can respectively slide along the first adjustment slot 11 and the second adjustment slot 25, so that the first slider 12 and the second slider 26 can respectively slide flexibly along the first chute 10 and the second chute 24. By adjusting the positions of the first slider 12 and the second slider 26 in the first chute 10 and the second chute 24 respectively, the multiple rotating connection blocks 15 and the support rods 29 can be adjusted to open or close, and then the positions of the rotating connection blocks 15 and the support rods 29 can be changed to adapt to the cantilever platforms 3 of different shapes, so that the first slider 12 and the second slider 26 respectively correspond to the lower suspension rods 36 one by one. At this time, the construction workers release the stay cable wound on the stay cable roller 16, connect the stay cable 19 to the first adjustment block 33 provided on the upper connection shaft 30 at the end of the support rod 29, so that the stay cable 19 and the support rod 29 form a stable triangular stay cable structure. The stay cable 19 and the first adjustment block 33 are fixed by an anchoring method. The specific anchoring structure belongs to the prior art and will not be elaborated here.

[0043] After the stay cables 19 are fixed, the construction workers connect the support rod 29 to the lower suspension rod 36 by pulling up the cable 43. The upper end of the pulling cable 43 is fixed to the second adjustment block 34 provided on the upper connecting shaft 30, and the lower end of the pulling cable 43 is fixed to the third adjustment block 42 provided on the lower connecting shaft 39. The pulling cable 43 is fixed to the second adjustment block 34 and the third adjustment block 42 respectively by using existing anchoring techniques. The support rod 29 bears pressure under the pulling of the stay cables 19 and the pulling cable 43. Since the lower suspension rod 36 is provided at the end of the cantilever platform 3, under the action of its own weight, the end of the cantilever platform 3 will produce a downward deflection. Therefore, the lower suspension rod 36 generates a downward pulling force on the pulling cable 43. On the contrary, the pulling cable 43 generates an upward pulling force on the lower suspension rod 36, so that the lower suspension rod 36 exerts an upward force on the end of the cantilever platform 3, effectively sharing the load at the end of the cantilever platform 3. At the same time, since the cantilever reinforcement assembly 5 is located below the cantilever platform 3, the integrity of the space above the cantilever platform 3 is ensured, avoiding the problem that the traditional cable structure is arranged above the cantilever platform 3, resulting in the occupation of space and affecting the appearance.

[0044] The construction workers can rotate the turning handle 44 to make the adjusting worm 18 rotate. The adjusting worm 18 drives the adjusting worm gear 17 to rotate, and the adjusting worm gear 17 drives the stay cable roller 16 to rotate, so that the stay cable 19 is wound back onto the stay cable roller 16 or released from the stay cable roller 16, changing the length of the stay cable 19 between the stay cable roller 16 and the upper connecting shaft 30. When the stay cable 19 is wound back onto the stay cable roller 16, the upper connecting shaft 30 moves upward under the pulling force of the stay cable 19, and the support rod 29 rotates upward in a pitching motion. The upper connecting shaft 30 pulls the lower connecting shaft 39 to deflect upward through the pulling cable 43, so that the lower suspension rod 36 drives the end of the cantilever platform 3 to deflect upward, further improving the bending deformation problem caused by the self-weight of the end of the cantilever platform 3 and increasing the structural stability. The winding amount of the stay cable 19 can be adjusted according to the actual situation to meet the construction requirements of different cantilever structures, realizing the adjustability during the construction stage and the co-deformation during the use stage. At the same time, by setting the stay cable 19 and the pulling cable 43, the cantilever reinforcement assembly 5 forms a flexible structure, which has stronger seismic resistance and environmental adaptability compared with the traditional rigid structure. The adjusting worm 18 and the adjusting worm gear 17 together form a worm and worm gear structure, and the worm and worm gear structure has a self-locking function, realizing the self-locking effect during the rotation of the stay cable roller 16 and ensuring the stability of the stay cable 19.

[0045] The first adjusting block 33 and the second adjusting block 34 can slide in the upper adjusting groove 31, and the third adjusting block 42 can slide in the lower adjusting groove 40. When the stay cable 19 pulls the upper connecting shaft 30, the first adjusting block 33, the second adjusting block 34 and the third adjusting block 42 can adaptively slide in the upper adjusting groove 31 and the lower adjusting groove 40 respectively according to the change of the relative positions of the upper connecting shaft 30 and the lower connecting shaft 39, so that the forces on the stay cable 19 and the lifting cable 43 are more reasonable.
