Problems solved by technology

It is a waste of national resources, and the vibration molding is used, the interior of the concrete is not dense, and its durability cannot be guaranteed
Hollow square pile: In addition to the above disadvantages, the square pile has more concrete materials distributed on four sides and smaller in the middle, and the distribution of steel bars is uneven. Due to the different gravity during centrifugal forming, the concrete at the four corners is difficult to centrifugally compact, that is, it is difficult to form. Poor bending and shear resistance

Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing description and specific embodiment:

[0024] Such as Figures 1 to 4 Shown a kind of centrifugal molding mold that is used to make concrete hexagonal pile, comprises upper mold body 1 and lower mold body 2, after described upper mold body 1 and lower mold body 2 closed molds, its inner cavity cross section is Hexagonal, the bottom surface of the upper mold body 1 and the side pass through the arc 3, the arc angle θ is 30-120°, the arc radius R is 5-50mm, the lower mold body 2 The bottom surface and the side are transitioned through the arc 3, and the arc angle θ of the stress relief is 30-120°. The radius R of the arc is 5-50 mm. A plurality of running wheels 4 that make the mold rotate on the centrifuge, the distance between the two adjacent running wheels 4 is two meters, and the running wheels are added by analogy according to the length of the pipe mold; the upper mold b...

Abstract

The invention discloses a centrifugal moulding mould used for manufacturing concrete hexagonal piles, which comprises an upper mould body and a lower mould body and is characterized in that: after the upper mould body and the lower mould body are closed, the cross section of an inner cavity is hexagonal; the upper mould body and the lower mould body are provided with a plurality of running wheels which make the mould rotated on a centrifugal machine; and the upper mould body and the lower mould body are fixedly connected through screws. The invention aims to overcome the defects of the prior art and provide a centrifugal moulding mould having a simple structure and used for manufacturing concrete hexagonal piles which have the performance such as bending resistance, shear resistance, high bearing capacity and withdrawal resistance much higher than that of tubular piles, square piles and hollow square piles.

Description

technical field [0001] The invention relates to a centrifugal forming mold for making concrete hexagonal piles. Background technique [0002] There are many pile foundation materials used in construction projects in the market, mainly including pipe piles and square piles. The square piles mentioned therein include hollow square piles and solid square piles. [0003] Pipe pile: It is cylindrical. It rotates at high speed on the centrifuge through the centrifugal pipe mold, so that the concrete material is shaped along the outer edge of the pipe mold cavity and performs high-speed centrifugal movement, and finally centrifuged into concrete pipe piles. This process is very mature and has entered large-scale industrial production. The disadvantage is that the concrete has high strength, high brittleness and low bearing capacity. [0004] Square pile: The friction with the ground is greater, and the bearing capacity is larger than that of the pipe pile, but the square pile co...
