Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a construction platform for a load-bearing beam with a cross slope. Background Technology

[0002] Cross slope refers to the slope of the bridge's load-bearing beam in the transverse direction (perpendicular to the bridge's axis). Its design and construction have a significant impact on the overall structure and function of the bridge. It prevents long-term water accumulation on the bridge deck, reduces the risk of concrete erosion and freeze-thaw damage, provides structural support for the bridge deck's cross slope, and ensures smooth drainage of the bridge deck.

[0003] In existing technology, the angle of the load-bearing beam is changed by setting a bracket at the lower end of the load-bearing beam, thereby casting the cross slope of the load-bearing beam. Since the bracket is prefabricated, errors will occur during the subsequent installation of the construction platform and the connection of the load-bearing beam. The bracket cannot guarantee the connection accuracy of the load-bearing beam. The height of the bracket needs to be adjusted later to meet the casting requirements, which prolongs the construction time and makes it difficult to guarantee the connection accuracy. Utility Model Content

[0004] In view of the technical problems existing in the background art, the purpose of this utility model is to provide a construction platform for the cross slope of the load-bearing beam, which can adjust the angle of the load-bearing beam according to the required inclination of the cross slope to be poured, so as to facilitate the pouring of the inclined cross slope at the top of the pier column.

Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] Example

[0027] like Figures 1-5As shown, a construction platform for a load-bearing beam with a cross slope includes a load-bearing component 2 and a slope adjustment device installed on the upper end of the load-bearing component 2. The load-bearing component 2 is connected between adjacent piers 1. The load-bearing component 2 includes an upper load-bearing plate 21 and a lower load-bearing plate 22. The load-bearing component 2 serves as the main structure of the construction platform. A connecting rod 23 is provided between the upper load-bearing plate 21 and the lower load-bearing plate 22. The slope adjustment device is installed on the upper load-bearing plate 21. Workers work inside the load-bearing component 2 to connect the load-bearing beam 3 between adjacent piers 1. The slope adjustment device includes a pad 5, a driving component 4, and several stabilizing components A. The pad 5 is detachably connected to the load-bearing component 2 by bolts, which meets the connection strength requirements while facilitating disassembly and assembly. A slot 51 is provided in the middle of the pad 5, and the driving component 4 is installed in the slot 51. The slot 51 prevents the driving component 4 from sliding on the pad 5. The drive component 4 is moved to maintain stability during operation and also serves as a positioning tool, facilitating its installation. The drive component 4 is a cylinder, but other telescopic structures are also possible. The drive component 4 includes a cylinder body 41 and several support rods 42 arranged around the cylinder body 41. The stabilizing component A and the support rods 42 are aligned. A shaft is provided on the cylinder body 41, which extends and retracts within the cylinder body 41. The load-bearing beam 3 is hinged to the upper end of the shaft. The extension and retraction of the shaft within the cylinder body 41 causes the load-bearing beam 3 to rise or fall. Several drive components 4 are evenly distributed at the lower end of the load-bearing beam 3. The angle of the cross slope to be poured is calculated, and the drive components 4 at different positions are adjusted so that the drive components 4 lift the load-bearing beam 3 to the tilt angle. The entire structure is easy to adjust, and the adjustment process has high precision, which facilitates the subsequent pouring of the cross slope and can greatly reduce the construction time.

[0028] like Figures 1-5 As shown, several stabilizers A are evenly distributed around the pad 5. One end of stabilizer A is connected to the pad 5, and the other end is connected to the drive component 4. Stabilizer A includes a stabilizer base 7, a connecting rod 6, and a stabilizer head 8. The stabilizer head 8 is hinged to one end of the connecting rod 6, and the stabilizer head 8 and the support rod 42 are detachably connected. The pad 5 is provided with a groove 52, and one end of the stabilizer base 7 is provided with a slider 71. The slider 71 is slidably connected in the groove 52, which passes through the pad 5. The stabilizer base 7 can be separated from the pad 5 for easy disassembly and assembly. The slider 71 moves directly along the groove 52. The stabilizer 7 and the pad 5 can be installed by sliding them in. The stabilizer 7 and one end of the connecting rod 6 are hinged. Positioning plates 72 are provided on both sides of the stabilizer 7. The pad 5 is provided with a connecting hole I 53, which is located on one side of the slide groove 52. The positioning plate 72 is provided with a connecting hole II 73. Positioning pins are detachably installed in the connecting holes I 53 and II 73. Adjust the position of the stabilizer 7 so that the connecting holes I 53 and II 73 are aligned. Insert the positioning pins into the connecting holes I 53 and II 73 to fix the stabilizer 7 on the pad 5.

[0029] like Figures 2-5As shown, the stabilizing head 8 includes abutment block I 81 and abutment block II 82. Abutment block I 81 and abutment block II 82 are arc-shaped and detachably connected by bolts. Abutment block I 81 and abutment block II 82 are spliced ​​into a ring. An annular groove I 811 is provided on the inner side of abutment block I 81, and an annular groove II 821 is provided on the inner side of abutment block II 82. Anti-slip pad I 9 is provided in annular groove I 811, and anti-slip pad II 91 is provided in annular groove II 821. Anti-slip pad I 9 and anti-slip pad II 91 are respectively attached to the support rod 42. Abutment block I 81 and abutment block II 82 are located on the outer side of support rod 42. Anti-slip pad I 9 and anti-slip pad II 91 increase the friction between stabilizing head 8 and support rod 42, preventing stabilizing head 8 from sliding on support rod 42, and making the overall support of drive component 4 more stable. Calculate the connection position of the stabilizer head 8 based on the dimensions of the drive component 4. First, insert the stabilizer seat 7 into the slide groove 52, place the anti-slip pad I 9 into the annular groove I 811, and then place the anti-slip pad II 91 into the annular groove II 821. Connect the abutment block I 81 and abutment block II 82 to the set position, so that the anti-slip pad I 9 and anti-slip pad II 91 abut against the support rod 42 respectively. During the installation of the stabilizer head 8, the stabilizer head 8 drives the stabilizer seat 7 to slide in the slide groove 52 through the connecting rod 6. Fix the abutment block I 81 and abutment block II 82 together with bolts and observe the positioning. The position between plate 72 and pad 5 is such that connecting hole I 53 and connecting hole II 73 are aligned. A positioning pin is screwed into connecting hole I 53 and connecting hole II 73 to fix the stabilizer 7 on pad 5. At this time, the stabilizer A is fixed. In order for the load-bearing beam 3 to be in an inclined state, multiple drive components 4 need to work synchronously. The force on different drive components 4 is uneven. If the stabilizer A is not set, when the load-bearing beam 3 is inclined, the load-bearing beam 3 is prone to exert large stress on the drive component 4, and the drive component 4 is prone to tilting, which may lead to a safety accident.

[0030] Working principle: After the load-bearing component 2 is built on the ground, the pad 5 is connected to the upper part of the upper load-bearing plate 21 by bolts. The drive component 4 is placed in the slot 51. The position of the stabilizer A is adjusted so that the stabilizer A is supported around the drive component 4. The load-bearing component 2 is hoisted to the pier 1 for installation. Then the load-bearing beam 3 is hoisted to the slope adjustment device. The installation position of the load-bearing beam 3 is calculated according to the inclination of the cross slope. Different drive components 4 are driven to work to tilt the load-bearing beam 3, which facilitates the subsequent separate casting of the cross slope of the load-bearing beam 3.

[0031] This is merely a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
