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 architectural and structural design. It extends part of the structure into the air, without relying on the support below, and only bears the load through the cantilever structure. This design technique not only creates a unique architectural form and spatial effect, but also puts forward higher requirements on structural design and construction technology. In the actual construction process, it is necessary to pay attention to the reinforcement of the cantilever structure.

[0003] Existing cantilever structure reinforcement methods mainly include bonded steel reinforcement, carbon fiber reinforcement and reinforcement by adding additional components, among which the method of adding additional components is more common, such as adding reinforced concrete columns or diagonal braces at the ends of cantilever structures. However, the reinforced concrete columns and diagonal braces together with the cantilever platform constitute a rigid structure, which makes it difficult to achieve adjustability in the construction phase and coordinated deformation in the use phase. At the same time, when reinforcing cantilever structures with complex shapes, the adaptability of standardized components to special-shaped structural surfaces is poor, resulting in difficulty in controlling construction accuracy. Existing cantilever structure reinforcement can also be achieved by setting cables above the cantilever structure to share the load at the ends 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 building engineering is proposed to solve the problems existing in the existing cantilever structure reinforcement method. Summary of the invention

The inclined steel cables are connected to the ends of the supporting rods to form a stable cable structure; (2) According to the shape of the cantilever platform, the construction workers evenly fixedly set the lower suspension rod at the end of the lower wall of the cantilever platform, and connected the support rod to the lower suspension rod through the lifting steel cable. The support rod is under pressure under the pull of the inclined steel cable and the lifting steel cable.

(4) The first adjustment block and the second adjustment block can slide in the upper adjustment groove, and the third adjustment block can slide in the lower adjustment groove. When the inclined steel cable pulls the upper connecting shaft, the first adjustment block, the second adjustment block and the third adjustment block can adaptively slide in the upper adjustment groove and the lower adjustment groove respectively according to the change of the relative positions of the upper connecting shaft and the lower connecting shaft, so that the force of the inclined steel cable and the pulling steel cable is more reasonable.

[0026] Working principle and workflow: According to the pre-designed plan, the construction personnel firstly tie the first anchor rib 8 provided on the first connecting plate 7 and the second anchor rib 22 provided on the second connecting plate 21 to the internal steel bars of the supporting pier 4 respectively, so that the first connecting plate 7 and the second connecting plate 21 can be firmly connected to the supporting pier 4 when casting the supporting pier 4, so that the steel cable adjustment assembly 6 and the rod adjustment assembly 20 are firmly fixed on the supporting pier 4. After the installation is completed, the construction personnel evenly fix the lower suspension rod 36 at the end of the lower wall of the cantilever platform 3 according to the shape of the cantilever platform 3. During the specific construction, the third anchor rib 38 provided on the third connecting plate 37 can be tied to the internal steel bars of the cantilever platform 3. When casting the cantilever platform 3, the third connecting plate 37 can be firmly connected to the cantilever platform 3, so that the lower suspension rod 36 is firmly fixed on the lower wall of the cantilever platform 3.

[0027] The construction personnel 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 respectively. At this time, the first sliding screw 13 and the second sliding screw 27 can slide along the first adjustment gap 11 and the second adjustment gap 25 respectively, so that the first slider 12 and the second slider 26 can slide flexibly along the first slide groove 10 and the second slide groove 24 respectively. By adjusting the positions of the first slider 12 and the second slider 26 in the first slide groove 10 and the second slide groove 24 respectively, multiple The rotating connecting block 15 and the support rod 29 are opened or retracted, thereby changing the position of the rotating connecting block 15 and the support rod 29 to adapt to cantilever platforms 3 of different shapes, so that the first slider 12 and the second slider 26 correspond to the lower suspension rod 36 respectively. At this time, the construction personnel release the inclined steel cable 19 wound on the inclined winding roller 16, and connect the inclined steel cable 19 with the first adjusting block 33 set on the upper connecting shaft 30 at the end of the support rod 29, so that the inclined steel cable 19 and the support rod 29 form a stable triangular cable structure, and the inclined steel cable 19 and the first adjusting block 33 are fixed by anchoring. The specific anchoring structure belongs to the prior art and will not be repeated here.

[0028] After the inclined steel cable 19 is fixed, the construction personnel connect the support rod 29 with the lower suspension rod 36 through the lifting steel cable 43. The upper end of the lifting steel cable 43 is fixed to the second adjustment block 34 set on the upper connecting shaft 30, and the lower end of the lifting steel cable 43 is fixed to the third adjustment block 42 set on the lower connecting shaft 39. The lifting steel cable 43 is fixed to the second adjustment block 34 and the third adjustment block 42 respectively by the existing anchoring technology. The support rod 29 is under pressure under the pulling of the inclined steel cable 19 and the lifting steel cable 43. Since the lower suspension rod 36 is set on the cantilever platform 3 At the end, the cantilever platform 3 will have a downward deflection under the action of its own weight, so the lower suspension rod 36 generates a downward pulling force on the pulling cable 43, and 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 applies an upward force to 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 component 5 is located below the cantilever platform 3, the integrity of the space above the cantilever platform 3 is guaranteed, avoiding the problem of traditional cable structure being set above the cantilever platform 3, resulting in space being occupied and affecting the appearance.

[0029] The construction personnel can rotate the adjusting worm 18 by turning the screw handle 44, and the adjusting worm 18 drives the adjusting worm wheel 17 to rotate, and the adjusting worm wheel 17 drives the inclined winding roller 16 to rotate, so that the inclined steel cable 19 is wound back onto the inclined winding roller 16 or released from the inclined winding roller 16, so that the length of the inclined steel cable 19 between the inclined winding roller 16 and the upper connecting shaft 30 changes. When the inclined steel cable 19 is wound back onto the inclined winding roller 16, the upper connecting shaft 30 moves upward under the pulling force of the inclined steel cable 19, and the support rod 29 pitches upward, and the upper connecting shaft 30 pulls the lower connecting shaft 39 to deflect upward through the lifting steel cable 43, so that the lower suspension rod 36 drives the end of the cantilever platform 3 to deflect upward. In order to further improve the bending deformation problem caused by the deadweight of the end of the cantilever platform 3 and increase the stability of the structure, the winding amount of the inclined steel cable 19 can be adjusted according to actual conditions to adapt to the construction requirements of different cantilever structures, thereby realizing the adjustability in the construction stage and the coordinated deformation in the use stage. At the same time, by arranging the inclined steel cable 19 and the pulling steel cable 43, the cantilever reinforcement component 5 forms a flexible structure. Compared with the traditional rigid structure, it has stronger seismic resistance and environmental adaptability. The adjusting worm 18 and the adjusting worm wheel 17 together form a worm gear structure. The worm gear structure has a self-locking function, which realizes the self-locking effect of the inclined winding roller 16 during the rotation process and ensures the stability of the inclined steel cable 19.

[0030] The first adjustment block 33 and the second adjustment block 34 can slide in the upper adjustment groove 31, and the third adjustment block 42 can slide in the lower adjustment groove 40. When the inclined steel cable 19 pulls the upper connecting shaft 30, the first adjustment block 33, the second adjustment block 34 and the third adjustment block 42 can adaptively slide in the upper adjustment groove 31 and the lower adjustment groove 40 respectively according to the change of the relative position of the upper connecting shaft 30 and the lower connecting shaft 39, so that the force of the inclined steel cable 19 and the pulling steel cable 43 is more reasonable.
