AI Technical Summary
In existing technologies, holes need to be drilled on the bridge beam surface for tie rod support during the construction of the base plate formwork, which increases maintenance costs. Furthermore, the support fixtures cannot be adjusted according to the size of the base plate formwork, making them inconvenient to use.
The structure employs movable columns and movable plates. By moving the movable columns on the fixed sleeves and rotating the movable plates, combined with the protective wall support mechanism, the length and angle of the support fixture can be adjusted, avoiding the need for drilling supports and adapting to base plate templates of different sizes.
This improved the applicability of the support fixtures, prevented concrete bulging, reduced maintenance costs, and enhanced the stability and flexibility of the supports.

[0021] Please refer to Figures 1-3The support mechanism 40 of the protective wall comprises a first mounting base 41, a second mounting base 42, an extension screw 43, a limiting clamp 44 and a backing plate 45. The two first mounting bases 41 are respectively arranged on the movable column 32 and the movable plate 34 near one end of the protective wall 20. The second mounting base 42 is arranged on the protective wall 20. The two extension screws 43 are arranged between the second mounting base 42 and the two first mounting bases 41. The structure of the extension screw 43 is an extension sleeve and a threaded rod connected by threads at both ends. The two limiting clamps 44 are symmetrically arranged on one end of the second mounting base 42 near the protective wall 20. One end of the two limiting clamps 44 penetrates the expansion joint on the protective wall 20. The expansion joint is 2m per lane on the protective wall 20. The support tool is arranged at the horizontal position of the expansion joint. The backing plate 45 is arranged between the curved position of one end of the two limiting clamps 44 and the protective wall 20. The limiting clamp 44 is inserted into the expansion joint. The curved position of one end of the limiting clamp 44 abuts against the backing plate 45 and the protective wall 20. The limiting clamp 44 and the second mounting base 42 are fixed at the expansion joint position on one side of the protective wall 20. The length of the extension screw 43 is changed by rotating the threaded rod of the extension screw 43. The extension screw 43 can be installed between the first mounting base 41 and the second mounting base 42 by the fixing pin. Thus, the movable column 32 and the movable plate 34 are supported at one end. The movable plate 34 is prevented from moving randomly. The second mounting base 42 is fixed at the expansion joint position. The punching operation of the pull rod is not needed. The maintenance cost of the bridge is reduced. The use is more convenient.
[0022] The function principle of the present application can be described by the following operation modes:
[0023] In use, the second mounting base 42 and the movable column 32 at both ends of the fixing sleeve 31 are placed on the expansion joint of the protective wall 20, the expansion joint of the ordinary concrete beam is 2m per lane, and the spacing of the plurality of supporting tools is also 2m per lane. The limiting clamp 44 on one side of the second mounting base 42 extends into the expansion joint. The spacer plate 45 is placed between the bending portion at one end of the limiting clamp 44 and the protective wall 20. The limiting clamp 44 and the second mounting base 42 are fixed on the protective wall 20. The bolt 33 is pulled out to make the movable column 32 extend out of the fixing sleeve 31. The two movable plates 34 are arranged on the outer sides of the two base plate forms 10, respectively. The bolt 33 is inserted into the through slot 321 on the movable column 32 to fix the positions of the two movable plates 34. When the two base plate forms 10 have a height difference, the two knobs 354 on the first threaded rod 353 are unscrewed. The rotating seat 352 at the top of the movable plate 34 can rotate around the first threaded rod 353 on the fixing seat 351. The rotating seat 352 and the movable plate 34 can be in a vertical state. The two knobs 354 are screwed into the first threaded rod 353 to tightly contact the two outer sides of the rotating seat 352. The angle of the rotating seat 352 is fixed, so that the movable plate 34 is always in a vertical state. The cushion block 363 is placed between the supporting block 362 and the base plate form 10. The second threaded rod 361 on the movable plate 34 is rotated to make the supporting block 362 at one end of the second threaded rod 361 close to the base plate form 10 and contact and fix the cushion block 363. The vertically arranged movable plate 34 makes the supporting block 362 at one end of the second threaded rod 361 abut against and press the cushion block 363 to improve the stability of the support on the base plate form 10. The support of the two telescopic screws 43 on the movable plate 34 and the support of the supporting block 362 on the base plate form 10 on the movable plate 34 make the base plate form 10 not move randomly during concrete pouring, preventing the phenomenon of mold expansion. The second mounting base 42 does not need to be additionally punched at the expansion joint position, reducing the maintenance cost.
[0024] Obviously, various modifications and changes can be made to the present application by those skilled in the art without departing from the spirit and scope of the application. Accordingly, it is intended that all such modifications and changes be included within the scope of the application as claimed.
