Do benefit to mould of preparation H type concrete pile that handling was evaporated and is supported

Technical Field

The utility model belongs to the technical field of the pile foundation engineering of all kinds of building structure systems, especially, relate to a mould for preparing H type concrete pile.

Background

According to the shape of the pile, the common concrete prestressed pile comprises a tubular pile, a square pile, a T-shaped pile, an H-shaped pile and the like, and various types of piles have respective characteristics and can be selected and used according to different occasions and environments. Taking an H-shaped pile as an example, the H-shaped pile comprises two flanges and a web plate connected with the two flanges, the cross section of the H-shaped concrete pile is in an H shape formed by the two flanges and the web plate connected with the two flanges, and the two flanges and the web plate form groove parts extending along the length direction of a pile body on two sides of the H-shaped concrete pile. Compared with the concrete pile with a round, square, T-shaped or other cross section shapes, the H-shaped concrete pile has better stability in resisting lateral soil pressure, water pressure, waves and overturning. Therefore, the H-shaped concrete pile is suitable for foundation pit maintenance, slope stabilization and river bank protection engineering.

For example, a Chinese patent application No. CN201610197475.3 (with a publication No. CN 105643776A) of 'a mold for preparing an H-shaped concrete pile' discloses a mold for preparing an H-shaped concrete pile, which comprises a left template, a right template and a lower template, wherein the lower template is positioned between the left template and the right template; the left template and the right template are driven by the overturning driving mechanism to overturn and can enclose a cavity matched with the shape of the H-shaped concrete pile together with the lower template; the method is characterized in that: the left template is hinged on the left moving seat, and the right template is hinged on the right moving seat; the turnover driving mechanism comprises a left turnover oil cylinder and a right turnover oil cylinder, wherein the left turnover oil cylinder is installed on the left movable seat and hinged with the left template, and the right turnover oil cylinder is installed on the right movable seat and hinged with the right template. The structure enables the left and right templates to be driven to overturn by the overturning oil cylinder, and can also slide left and right synchronously with the overturning oil cylinder, thereby facilitating demoulding when manufacturing H-shaped concrete piles with complex structures.

The whole die for preparing the H-shaped concrete pile is fixed in a factory building and cannot move, so that the H-shaped concrete pile can be steamed only in situ, and compared with the traditional steaming pool, the in-situ steaming is low in steaming efficiency, long in steaming time and greatly increased in die production cost. The in-situ steam curing needs to pertinently transform the factory building, the existing pipe pile factory building can not be directly used, the factory building and the foundation need to be additionally built, the construction of a new factory building and a foundation needs to spend huge resources, and the investment of investors who originally have the pipe pile factory building is greatly increased.

Therefore, the existing H-shaped supporting pile mould can be further improved.
