It is each pre- since the stretching force of precast concrete pile tensioning equipment does not act on precast concrete square pile mold 1
The bottom template 2 of concrete square pile die 1 processed and the steel plate thickness of side template 3 can be 1.5-6mm, the utility model it is pre-
The bottom template 2 of concrete square pile die 1 processed and the thickness of side template 3 are far smaller than the bottom of current precast concrete square pile mold
The thickness of portion's template and side template, and bottom template 2 and the length of side template 3 is generally at 10 meters or more, the utility model it is pre-
Concrete square pile die 1 processed can greatly reduce the dosage of steel, and the cost of precast concrete square pile mold is greatly reduced.And
And bottom template 2 due to the precast concrete square pile mold 1 of the utility model and side template 3 are the steel of thickness 1.5-6mm
Plate, side template 3 is because relatively thin have certain elasticity and intensity, and in demoulding, side template 3 can produce a certain amount of deformation,
Precast concrete square pile is facilitated to deviate from from square pile die.After precast concrete square pile deviates from mold, side template 3 is because have one
Fixed elasticity and intensity, can recover immediately original state.Gap 9 between every two adjacent precast concrete square pile mold 1 is big
Small is 3-30mm, is connected on the outside of the end of two pieces of side templates 3 of adjacent non-same precast concrete square pile mold 1 with connector
It connects, the outer wall of outermost two pieces of side templates 3 is provided with muti-piece stiffener plate 4, two adjacent precast concrete square pile molds 1
Between gap 9 it is smaller, two pieces can be not added stiffener plate 4 and can be supported mutually with the adjacent side template 3 that connector connects, side
Template 3 can restore to the original state.
It is preferred that the bottom template 2 of each precast concrete square pile mold 1 and the steel plate thickness of side template 3 are 2.5-
4.5mm, precast concrete square pile set of molds may include 2-10 precast concrete square pile mold 1.Bottom template 2 and side template
When 3 steel plate thickness is 1.5mm or so, side template 3 elasticity it is poor, intensity is lower, need with more stiffener plate 4 come
Increase elasticity and intensity.When the steel plate thickness of bottom template 2 and side template 3 is 6mm or so, the elasticity of side template 3 is poor, strong
Degree is higher, and rolled steel dosage is also larger.The bottom template 2 and side template 3 of precast concrete square pile mold 1 are thickness 2.5-
The steel plate of 4.5mm, can make precast concrete square pile mold 1 have preferable elasticity and intensity, and side template 3 has preferable restore
