Embodiment Construction

[0013] As shown in the figure, the manufacturing method of bridge hollow beam steel inner mold of the present invention is prepared according to the following steps:

[0014] a. Make the cylinder column 1 with steel plate, and the external dimension of the cylinder column 1 is consistent with the size of the hollow hole of the hollow beam to be poured; Weld a liner 3 to seal the longitudinal tube seam 2;

[0015] b. Weld the telescopic rod 4 in the radial direction in the cylinder cavity of the column 1, one end of the telescopic rod 4 is welded with the lining plate 3, and the other end is welded with the inner wall of the column 1; The number of rods 4 is determined according to the length of the column 1, and can be arranged at one, two or more intervals. In order to improve the supporting strength of the column 1 , a supporting member 5 is detachably arranged in the cavity of the column 1 . In order to facilitate the butt joint of the multi-section column 1 when the pour...

Abstract

The present invention discloses a method for manufacturing bridge hollow beam steel internal mould. Said method includes the following steps: (a) making steel sheet into cylinder, the external dimension of said cylinder is identical to hollow hole dimension of hollow beam to be moulded; on one longitudinal edge of longitudinal cylinder seam of the cylinder, along its inner surface welding a lining board for blocking the longitudinal cylinder seam; and (b) in the described cylinder cavity of the cylinder, along radial direction welding a telescopic device, one end of said telescopic device is welded with the described lining board, and its another end is welded with inner wall of cylinder, the number of the telescopic devices is dependent to the length of cylinder, can be one, two or several telescopic devices which are mutually spaced.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a method for manufacturing a bridge hollow beam steel inner mold. Background technique [0002] At present, the hollow beam inner mold used in bridge construction projects has always used rubber airbags to replace the steel inner mold. The reason is that the steel inner mold cannot be taken out from the hollow beam after the hollow beam is poured. The rubber airbag is used as the inner mold of the hollow beam. After the hollow beam is poured, the air in the airbag can be released to take out the airbag conveniently. However, there are deficiencies in the floating form in the process of pouring the hollow beam by using the rubber airbag inner mold, which reduces the quality of the beam body and buryes hidden dangers for the use of the hollow beam. Contents of the invention [0003] The object of the present invention is to provide a method for manufacturing a steel inner mold...
