Description

A high-speed railway embankment section catenary foundation pre-embedded bolt fixed formwork

technical field

The utility model relates to a formwork, in particular to a formwork fixed by pre-embedded bolts of a catenary foundation in a high-speed railway embankment section.

technical background

At present, the catenary foundation construction of the railway subgrade section is basically carried out by the civil engineering construction unit. After the catenary foundation is constructed, it is handed over to the Sidian construction unit to install the catenary column. However, during the delivery process, there are often a large number of catenary embedded bolts. If the requirements are met, the leakage length of the catenary pre-embedded bolts is insufficient, and the catenary pre-embedded bolts are not vertically offset, resulting in the failure of the catenary column to be installed, and the receiving unit does not accept it and rework occurs.

Contents of the invention

In order to solve the above problems, the utility model proposes a high-speed railway embankment section catenary foundation pre-embedded bolt fixed formwork.

The technical solution of the utility model is: a high-speed railway embankment section catenary foundation pre-embedded bolt fixing formwork, including: lower frame, nut, upper frame, adjusting screw, reinforcing rod, horizontal bridge, and pre-embedded bolts; The lower frame is welded by threaded steel, and the lower frame is connected with the upper frame through reinforcing rods; the adjusting screw is welded on the lower frame; the upper frame is provided with embedded bolt holes; the embedded bolt holes are formed by The threaded steel is welded; the embedded bolts are installed in the embedded bolt holes and fixed with nuts; the horizontal laps are welded on the upper frame for placing the formwork on the formwork.

Further, there are eight adjusting screws, which are respectively welded to the four sides of the lower frame.

Further, the number of said cross-legs is two, which are welded on the upper frame in parallel.

Further, the embedded bolts can be removed from the formwork.

Further, the diameter of the rebar is more than 16 mm.

Beneficial effect

A high-speed railway subgrade section catenary foundation pre-embedded bolt fixing formwork of the utility model can quickly and accurately locate and reinforce the pre-embedded bolts, prevent the distance between the bolt groups from exceeding the standard, and prevent the bolts from sinking during the pouring process and affect the bolts The leakage length can quickly and accurately adjust the position of the bolt before concrete pouring, which can greatly improve the accuracy and efficiency of the work.
