Description

Technical Field

[0001] The present application relates to the technical field of prefabricated beam preparation, and in particular to an adaptive pedestal for prefabricated beams of multiple sizes. Background Art

[0002] As the country continues to increase its investment in transportation infrastructure construction, the transportation industry has also achieved long-term development, especially in the increasing construction of bridges in my country. In order to meet the construction progress and project quality, prefabricated beams and slabs are used in the bridge construction process.

[0003] At present, the prefabrication of beams and slabs usually requires construction units to build their own prefabrication sites for prefabrication. During the prefabrication process, the steel bars of the prefabricated beams need to be placed on a pedestal for concrete pouring and shaping, and a beam end keyway needs to be left in the prefabricated beams of the bridge, that is, a beam end keyway template is left in the pedestal. The beam end keyway in the prefabricated beam is designed to improve the connection strength between the prefabricated beam and the lower prefabricated column. The keyway is usually located at the end of the prefabricated beam and is used to fix the connecting steel bars between the prefabricated beam and the lower prefabricated column. The shape of the keyway is usually U-shaped or rectangular, and the size is determined according to the specifications of the prefabricated beam and prefabricated column. The length of the keyway is usually greater than the diameter of the connecting steel bar to ensure that the connecting steel bar can be fully inserted into the keyway.

[0004] However, the traditional method of the pedestal is to use a steel-concrete structure. The notable feature of this structure is that the size cannot be changed after it is made. Combined with the fact that the pedestal required for the beam and slab prefabrication work is customized according to the beam and slab size of this project, when this project is completed, the pedestal cannot be reused, and the abandoned pedestal needs to be broken down and become construction waste. This high cost, low efficiency, no secondary utilization rate, complex construction, and environmentally unfriendly disadvantages do not match the current concept of "green construction". Therefore, further improvements can be made. Summary of the invention

[0005] In order to improve the utilization rate of the pedestal and reduce the manufacturing cost of the pedestal, the present application provides an adaptive pedestal for prefabricated beams of multiple sizes.

The top of the supporting telescopic rod is installed on the supporting table and the bottom of the beam end keyway table. The rolling pulley is installed on the bottom of the supporting telescopic rod. The rolling pulley can be rotatably set in the limiting slide rail.

[0016] By adopting the above technical solution, when movement is required, the length of the supporting telescopic rod can be adjusted so that the height of the movable part is higher than the supporting bottom plate, so that the rolling pulley can slide in the limiting slide rail, thereby adjusting the spacing of the pedestal, thereby achieving adaptive adjustment for prefabricated beams of different sizes.

It plays an important role in the subsequent adjustment of the height of the moving parts.

The detachable connection allows the staff to quickly assemble or disassemble without the use of complicated tools, thereby improving work efficiency. In addition, the detachable connection increases the possibility of structural adjustment, so that the base can add or reduce support platforms 1 according to the requirements of different sizes.

[0041] refer to Figure 2 Specifically, in the present application, a locking cover 54 is provided between the support platform 1 and the adjacent support platform 1, and between the support platform 1 and the adjacent beam end keyway platform 2. The locking cover 54 is located at the top of the first fixing block 5 and the first fixing groove 6, the first fixing block 5 and the second fixing groove 8, and the second fixing block 7 and the first fixing groove 6.

When the precast beam does not need to cast the beam end keyway, the staff can cover the beam end groove 21 with the beam end cover 22, so that it can be used as a normal support platform 1, thereby realizing repeated use of the platform.

[0043] refer to Figure 1 , 4 Specifically, in the present application, the movable part 3 includes a rolling pulley 31 and a supporting telescopic rod 32. The top of the supporting telescopic rod 32 is vertically installed on the bottom of the horizontally placed supporting table 1 and the beam end keyway table 2, and the bottom of the supporting telescopic rod 32 is fixedly connected to the rolling pulley 31.

[0044] The supporting telescopic rod 32 includes a supporting upper rod 321 and a supporting lower rod 322. The supporting lower rod 322 can be upwardly inserted into the supporting upper rod 321. A through upper rod hole 3211 is provided on the supporting upper rod 321, and a plurality of through lower rod holes 3221 are evenly provided on the supporting lower rod 322 along its length direction. When the supporting lower rod 322 is upwardly inserted into the supporting upper rod 321, the length of the supporting telescopic rod 32 can be adjusted by adjusting the positional relationship between the upper rod hole 3211 and the lower rod hole 3221.

The shock absorbing telescopic rods 332 include shock absorbing upper rods 3321 and shock absorbing lower rods 3322, and the diameter of the shock absorbing upper rods 3321 is larger than that of the shock absorbing lower rods 3322, so that the shock absorbing lower rods 3322 can be inserted into the shock absorbing upper rods 3321 to realize the telescopic action of the shock absorbing telescopic rods 332.

[0046] During actual use, when movement is required, the length of the supporting telescopic rod 32 can be adjusted so that the height of the movable part 3 is higher than the supporting base plate 4, so that the rolling pulley 31 can slide in the limiting slide rail 200, thereby adjusting the spacing of the pedestal, thereby achieving adaptive adjustment for precast beams of different sizes.

In actual use, the lifting ring 11 provides a clear lifting point, so that the table can be easily lifted and moved by a crane or other lifting equipment. It plays an important role in the subsequent adjustment of the height of the moving part 3. At the same time, by using the specially designed lifting ring 11, the stability and safety of the table can be ensured during the lifting process, reducing the risk of accidents caused by improper lifting.

[0048] The implementation principle of an adaptive pedestal for precast beams of multiple sizes in an embodiment of the present application is as follows: a pedestal of a traditional steel-concrete structure is transformed into a modular platform consisting of a plurality of movable combined support platforms 1 and a plurality of movable combined beam end keyway platforms 2; the spacing between the support platforms 1 and the beam end keyway platforms 2 can be adjusted according to the size of the precast beam to increase the adaptability of the pedestal.

[0049] The specific method is that when it is necessary to change the distance between the support table 1 and the beam end keyway table 2, the support table 1 or the beam end keyway table is lifted by connecting the crane and the lifting ring 11, and the staff adjusts the height of the rolling pulley 31 so that the rolling pulley 31 slides in the limiting slide rail 200 to leave space for placing the new support table 1 or the beam end keyway table 2, thereby achieving adjustable spacing, thereby increasing the utilization rate of the base, allowing for secondary use, and reducing construction costs.
