Embodiment 1

[0038] see Figure 1 to Figure 3 , which is a structural schematic diagram of a prefabricated cover beam and prefabricated column anti-seating protection device 100 provided in an embodiment of the present invention. Component 20. Wherein, a plurality of protective pieces 10 are connected to each other to form an accommodating cavity 11 for accommodating the prefabricated column 40 , and a plurality of locking assemblies 20 are circumferentially distributed on a side of the plurality of protective pieces 10 away from the accommodating cavity 11 .

[0039] A plurality of protective pieces 10 can prevent the sitting grout from overflowing from the connection between the prefabricated column 40 and the prefabricated cover beam during the lowering process of the prefabricated cover beam. On the one hand, the locking assembly 20 can support the corresponding protective piece 10, improving the bearing capacity of the protective piece 10, thereby avoiding the pressure damage of the ...

Embodiment 2

[0055] see Figure 7 , which is a schematic flowchart of a construction method for prefabricated cover beams and prefabricated columns to be grouted according to the second embodiment of the present invention. The construction method of the prefabricated cover beam and the prefabricated column is used to bond the connecting surfaces of the prefabricated column and the prefabricated cover beam together through the sitting grout. The construction method of the prefabricated cover beam and prefabricated column sitting slurry for example includes:

[0056] Step S10, setting the sitting slurry protection device 100 on the top of the prefabricated column 40, so that the upper end of the sitting slurry protection device 100 protrudes from the top of the prefabricated column 40 to form a sitting area 50 at the top of the prefabricated column 40;

[0057] Step S20, installing the second connecting piece 30, and adjusting the position of the protective piece 10;

[0058] Step S30, adj...

Abstract

The invention provides a bedding mortar protection device for a prefabricated bent cap and a prefabricated stand column, which is arranged at the joint of the prefabricated stand column and the prefabricated bent cap, and comprises a plurality of protection pieces which are connected with one another and define an accommodating cavity; each protective part comprises a first mounting panel and a second mounting panel which is connected to the top end of the first mounting panel and is far away from the accommodating cavity; and a locking assembly, the first end of the locking assembly is connected with the first mounting panel, and the second end of the locking assembly is connected with the second mounting panel. The technical problem that bedding slurry overflows is solved, and the technical effect of improving bedding slurry efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a grouting protection device for a prefabricated cover beam and a prefabricated column and a construction method for a prefabricated cover beam and a prefabricated column to be grouted. Background technique [0002] With the rapid development of our country's economy, our country's bridge construction has also developed rapidly. In the process of bridge construction, the prefabricated assembly construction technology can significantly shorten the construction period and reduce the construction time. At the same time, it has the advantages of high construction quality, low safety risk and environmental protection. Therefore, prefabricated assembly construction technology has been widely used in municipal bridge construction. [0003] As a key step in prefabricated assembly construction technology, sitting grouting construction can make the connection surface between t...
