The present application is described in further detail below with reference to the attached drawings and the detailed description.
As shown in fig. 1, the embodiment of the present application is applied to a cap beam 1 for a cylindrical pier, the cap beam 1 for a cylindrical pier includes a cap beam 13 having an inverted trapezoidal shape, and a cylindrical pier 11 supported below the cap beam 13 in a transverse bridge direction, and the supported cylindrical piers 11 are arranged in three or four in combination with a span width of the cap beam 13. The cylindrical pier 11 is cast in sections according to the existing method, and the capping beam 13 is erected on the cylindrical pier 11 by a pin rod method to construct the construction support structure 2 for cast-in-place.
With reference to fig. 1 and 2, the support structure 2 of the capping beam overhanging bottom die 12 of the present application is described in connection with a construction process.
And mounting pier brackets 21 on the constructed cylindrical piers 11. Pier bracket 21 is fixed with cylinder mound 11 through the steel pin stick, and the position that the steel pin stick was inserted needs to reserve the insert hole way through the built-in fitting that sets up in cylinder mound 11 inside, sets up according to the position of the spandrel girder 23 of follow-up installation pier bracket 21, specifically, sets up a pair of pier bracket 21 on every cylinder mound 11, and every pair of pier bracket 21 distributes to both sides along the horizontal bridge, and every pair of pier bracket 21 is fixed in following the direction of the bridge promptly for pier bracket 21 of the same one side of cylinder mound 11 can support a spandrel girder 23 jointly.
The bearing beam 23 is used as a main bearing structure of the capping beam construction and is supported by the pier corbels 21 on the cylindrical pier 11, specifically, the bearing beam 23 is arranged on two sides of the cylindrical pier 11 along the transverse bridge direction, and a stable frame structure is formed by connecting rods arranged at intervals. The two ends of the load beam 23 should extend beyond a part of the casting area of the bent cap 13 so as to be used as an operation platform.
And a frame falling device 22 is arranged between the bearing beam 23 and the pier bracket 21 and is used for falling the capping beam template. The drop frame equipment 22 comprises a combined drop frame wedge block, a steel cushion block arranged at the top of the combined drop frame wedge block and a jack 25 abutted between the pier bracket 21 and the bearing beam 23. The combined type falling wedge block comprises a pair of bases with adjustable intervals and cover plates placed on the bases, the cover plates and the bases are abutted by downward inclined surfaces, and when the intervals of the bases are increased, the cover plates slide downwards along the inclined surfaces, so that the falling process is realized. The steel cushion block is formed by welding profile steel and a thick steel plate into a whole. After the bracket is installed, the combined falling frame wedge block is placed in place, the combined falling frame wedge block is ensured to be located in the center position of the distance between the pin rod holes of the pier bracket 21, a constructor calculates the height of the top of the combined falling frame wedge block according to the design height of the bottom die system of the cover beam 13, and a settlement value with the height of 1.5cn is reserved. After the combined falling frame wedge block is installed, the combined falling frame wedge block and the top surface of the pier bracket 21 are limited and fixed, so that the transverse movement is avoided, and optionally, the combined falling frame wedge block and the pier bracket 21 are fixed in a spot welding mode. The jack 25 is used for adjusting the inclination angle of the bearing beam 23 so as to conform to the preset transverse gradient of the bent cap bottom die 12, and can be adjusted after the bent cap 13 template is installed, or can be used for pre-adjusting the bearing beam 23 before the bent cap 13 template is installed in place.
