Abstract

The present invention relates to a flange used for hollow concrete pile and a fabrication method thereof. By using a casting method, a metal flange used for ground foundation engineering can be fabricated by a single work procedure to improve the production capacity; projecting par are projecting to reinforce the rigidity of an iron core and reinforcing steel; an inner groove and an outer groove are formed outside the projecting part, thereby saving the flange material and preventing the lost of manufacture cost and steel plate. For this purpose, the invention provides a flange which is formed with a hollow part at the center, and projects parts arranged in round shape and with certain thickness on one side, and iron core burying holes and reinforcing steel burying holes are formed in the projecting parts and are communicated with each other. The invention is characterized in that the projects parts on the flange are connected via rigid reinforcing strips, thereby the rigidity of the iron core and reinforcing steel arranged in the projecting part is strengthened.

Description

technical field [0001] The invention relates to a flange for a hollow concrete member integrally formed on both sides of a hollow concrete member and supporting an iron core buried inside the concrete member along the length direction and two ends of a steel bar. Background technique [0002] Generally, flange joints are used on both sides of concrete members. Concrete elements can be illustrated by, for example, concrete piles used in ground foundation works. [0003] An opening is formed at the center of the flange, and when the concrete pile is driven into the ground, soil on the ground can overflow through the opening. Figure 1 is a plan view of a traditional metal flange used in ground foundation engineering. Fig. 2 is a cross-sectional view taken along line V-V in Fig. 1 . [0004] Referring to Fig. 1 and Fig. 2, in the civil engineering carried out before the construction of the building, the concrete pile driven in order to strengthen the weak ground is formed by ...
