Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in fig. 1 to 5, the present invention provides a technical solution: assembled precast beam pedestal die block, including prefabricated case roof beam and adjustable coarse aggregate standard funnel, prefabricated case roof beam sets up in adjustable coarse aggregate standard funnel's top, and prefabricated case roof beam is the box structure, and adjustable coarse aggregate standard funnel is the integrated configuration of fixed support structure 3 structure and coarse aggregate funnel structure 6 that adjusts through slidable stand 4.
In this embodiment, preferably, the prefabricated box girder includes a prefabricated box girder structure main body 1 and a box girder bottom end structure 2, and the prefabricated box girder structure main body 1 and the box girder bottom end structure 2 are of an integrated structure.
In this embodiment, preferably, coarse aggregate funnel structure 6 is uncovered cuboid structure, the both sides of coarse aggregate funnel structure 6 are provided with the U-shaped groove structure, fixed bearing structure 3 sets up at the top edge of coarse aggregate funnel structure 6, fixed bearing structure 3 is the platelike structure, the mounting height of fixed bearing structure 3 is highly unanimous with the top of coarse aggregate funnel structure 6, slidable formula stand 4 sets up in the bottom of fixed bearing structure 3, and fixed bearing structure 3 and slidable formula stand 4 welded fastening, slidable formula stand 4 is hollow cylindrical structure, be provided with the internal thread on slidable formula stand 4's the inner wall.
In this embodiment, it is preferred, still include stand adjusting bolt 5, stand adjusting bolt 5's top surface is provided with the external screw thread, stand adjusting bolt 5's bottom is provided with the square body base of a body structure, stand adjusting bolt 5 can screw up the inside of fixing at slidingtype stand 4 through the internal thread with the screwing of external screw thread, stand adjusting bolt 5's surface corresponds the below position of external screw thread and is provided with the scale mark, can be more clear and definite find the test height that the volume of different models rises and corresponds through slidingtype stand 4's scale mark, the fast-speed trouble of experimenter manual measurement has been saved, reduce human error, make the distance of 6 feed openings of coarse aggregate funnel structure and volume rise the mouth more easily control, thereby let the test result more accurate reliable, make whole testing process accord with the standard requirement more.
