DETAILED DESCRIPTION

[0035] In order to facilitate the understanding of the technical solution of the present invention, a detailed description is given below in conjunction with the accompanying drawings and specific embodiments.

[0036] Example 1

[0037] like Figure 1 As shown, a square pile mold with adjustable mold cavity size includes: an L-shaped plate 1 with a first template 11 and a second template 12; a first position adjustment mechanism installed on a template support frame 2 and capable of adjusting the distance between a third template 41 and the first template 11, and a second position adjustment mechanism installed on the template support frame 2 and capable of adjusting the distance between a fourth template 42 and the second template 12; wherein the L-shaped plate 1, the third template 41 and the fourth template 42 together form a mold cavity 44 that can be used to form square piles.

[0038] In the above structure, the first position adjustment mechanism drives the third template 41 to adjust the distance between the third template 41 and the first template 11, and the second position adjustment mechanism drives the fourth template 42 to adjust the distance between the fourth template 42 and the second template 12, so as to adjust the size of the mold cavity 44.

[0039] Specifically, the first position adjustment mechanism includes a plurality of first adjustment rods 411 perpendicular to the third template 41 and arranged at intervals along the length direction of the third template 41, one end of the first adjustment rod 411 is connected to the third template 41, and the other end of the first adjustment rod 411 passes through the template support frame 2; the first adjustment rod 411 is connected to the template support frame 2 through a detachable fastener 8;

[0040] And / or the second position adjustment mechanism includes a plurality of second adjustment rods 421 perpendicular to the fourth template 42 and arranged at intervals along the length direction of the fourth template 42, one end of the second adjustment rod 421 is connected to the fourth template 42, and the other end of the second adjustment rod 421 passes through the template support frame 2; the second adjustment rod 421 is connected to the template support frame 2 through a detachable fastener 8.

[0041] In the above structure, the third template 41, the fourth template 42 and the L-shaped plate 1 form a mold cavity 44, and a steam space for steam to enter is formed between the outside of the mold cavity 44 and the template support frame 2. The mold does not need to be hoisted into the steaming pool for steaming. The fourth template 42 can adjust the size of the mold cavity 44, that is, the size of the square pile by moving back and forth through the second adjusting rod 421. The third template 41 can adjust the size of the mold cavity 44 by moving the first adjusting rod 411 within a certain range. If it exceeds a certain range, the third template 41 can be directly replaced, and then the adjustment can be achieved by moving the fourth template 42. The above fastener 8 can be a fastening nut. In the above structure, mold parts are saved, the design is reasonable, reliable and material-saving, and the adjustment can be achieved by driving the first adjusting rod 411 and the second adjusting rod 421, which is convenient to operate.

[0042] In the above-mentioned square pile mold structure, what is produced is a concrete solid square pile, whose cross section is unchanged along the pile length, and it is easy to process and the manufacturing quality is easy to guarantee. However, with the development of the construction industry, there are higher requirements for the bearing capacity and pull-out resistance of the square pile, so the solid square pile with variable cross section also appears. The solid square pile with variable cross section can effectively increase the contact surface due to its concave and convex pile body, improve the bearing capacity and pull-out resistance of the square pile, but it also puts forward new tests for the processing mold and processing technology. In order to meet the square pile mold to produce variable cross section to realize square piles, the concave and convex bamboo section on the square pile mold, that is, the variable cross section part, can be realized by adopting different inner mold frames (the third template 41, the fourth template 42, the L-shaped plate 1).

[0043] like Figures 3 to 5 As shown, a plurality of detachable inner lining sheets 43 are installed at intervals on the cavity wall of the mold cavity 44 along the length direction of the mold cavity 44 , and the inner lining sheets 43 protrude in a direction away from the cavity wall.

[0044] The inner lining sheet 43 of the above structure can be installed on the cavity wall of the mold cavity 44 by snap-fitting, or can be fixed by screwing, or fixed by an embedded structure. The detachable connection of the inner lining sheet 43 is convenient for replacement and disassembly to adapt to the processing of various bamboo joint shapes and sizes. The simple replacement of the inner lining sheet 43 replaces the replacement method of the integral inner mold in the prior art. In addition to making the replacement operation more convenient, the mold opening cost can also be reduced.

[0045] Specifically, a protruding clamping support structure 441 is provided on the cavity wall of the mold cavity 44 , the inner lining sheet 43 is clamped and fixed to the clamping support structure 441 , and the inner lining sheet 43 is attached to the cavity wall of the mold cavity 44 .

[0046] In the above structure, the cavity wall of the mold cavity 44 is snap-fitted with the snap-fit ​​support structure 441 and the snap-fit ​​groove 431 on the inner lining sheet 43. The snap-fit ​​support structure 441 can be implemented by a support arm or a plurality of support point structures. The inner lining sheet 43 is installed by vertically sliding in or out against the inner end surface of the inner mold frame. The replacement operation is quick and convenient, and the snap-fit ​​support structure 441 has a guiding function to prevent the bamboo nodes of the pile body from deformation.

[0047] Specifically, the snap-fit ​​support structure 441 includes a support arm, which is arranged on the cavity wall of the mold cavity 44. The inner lining sheet 43 has an open slot 431 facing the cavity wall to match the support arm. The support arm slides into the inner lining sheet 43 through the open slot 431 to form a snap-fit ​​fit.

[0048] The length of the above-mentioned support arm can be set to be consistent with the width of the cavity wall of the mold cavity 44, or smaller than its width. Preferably, a longer length can effectively play a supporting and guiding role. Preferably, the support arms are arranged on both sides, which is conducive to ensuring the stable installation of the inner lining sheet 43. Of course, the cross-section of the support arm can adopt other conventional shapes in addition to T-shape, and can also be a dovetail shape or other special-shaped structures.

[0049] Specifically, the first adjusting rod 411 and the second adjusting rod 421 both include a screw segment, and the template support frame 2 is provided with a first adjusting rod through hole 2a matching the first adjusting rod 411 and a second adjusting rod through hole 2b matching the second adjusting rod 421, and the first adjusting rod through hole 2a and the second adjusting rod through hole 2b are threaded holes;

[0050] One end of the first adjusting rod 411 is rotatably connected to the third template 41, the screw section of the first adjusting rod 411 is threadedly connected to the first threaded through hole 2a, and the other end of the first adjusting rod 411 is externally connected to the power mechanism of the first position adjustment mechanism;

[0051] One end of the second adjusting rod 421 is rotatably connected to the fourth template 42, the screw section of the second adjusting rod 421 is threadedly connected to the second threaded through hole 2b, and the other end of the second adjusting rod 421 is connected to the power mechanism of the second position adjustment mechanism.

[0052] In the above structure, the first adjusting rod 411 and the second adjusting rod 421 drive the third template 41 and the fourth template 42 to move by being threadedly connected to the template support frame 2. The power mechanism can use a power motor or artificial external force. The threaded hole is set on the template support frame 2. In this technical solution, since the first adjusting rod 411 is threadedly connected to the first adjusting rod through hole 2a, and the second adjusting rod 421 is threadedly connected to the second adjusting rod through hole 2b, the first and second adjusting rods 411, 421 need to be rotatably connected to the third and fourth templates 41, 42, and the rotating connections are provided with bearings and bearing seats.

[0053] like Figure 6 As shown, the L-shaped plate 1 and the formwork support frame 2 are fixed by a quick buckle structure, the L-shaped plate 1 is an integrated structure, the formwork support frame 2 is a split structure, and the horizontal support frame and the vertical support frame of the formwork support frame 2 are also fixed by a quick buckle structure, and the quick buckle structure includes a lifting ring 31 and a buckle 32 that forms a detachable lock with the lifting ring 31. The lifting ring 31 has a hanging groove 311 for accommodating a buckle 321 of the buckle 32. The L-shaped plate 1 and the formwork support frame 2 are fixed by the quick buckle structure to facilitate replacement and locking operations.

The first and second adjustment rods 421 are also provided with fasteners 8. The function of the fasteners 8 is to prevent the first and second adjustment rods 421 from sliding relative to the template support frame 2.
