Description

Technical Field

[0001] The utility model relates to the technical field of PHC pile production, in particular to a PHC pile quick-installation mold. Background Art

[0002] PHC piles, full name Prestressed High-intensity Concrete Pipe Pile (Prestressed High-intensity Concrete), are a kind of slender hollow precast concrete components with equal cross-sections produced by professional manufacturers. The production process adopts advanced technologies such as prestressing by pre-tensioning method and adding finely ground materials and high-efficiency water reducing agent. The concrete is compacted by centrifugal dehydration and then steam-cured twice at normal pressure and high pressure. PHC piles have the characteristics of high pile body strength, strong penetration, stable and reliable quality, etc. They can withstand large anti-cracking bending moments and can remain intact in harsh construction environments.

[0003] The PHC pile mold is a special tool for manufacturing prestressed high-strength concrete (PHC pile). The process of manufacturing PHC piles usually includes steps such as pipe mold making, concrete mixing, concrete pouring, maintenance and demoulding. In the prior art, the PHC pile mold is usually an open and closed mold. Bolts and nuts are generally used to directly lock and fix the upper mold and the lower mold. When installing the mold, it is necessary to align the bolts with the positioning holes of the upper mold and the lower mold, and then tighten them one by one to fit the upper mold and the lower mold. The entire mold installation and fixing process is cumbersome, time-consuming, and inefficient. Utility Model Content

[0024] The utility model provides a PHC pile quick-assembly mold 100.

[0025] See also Figure 1-Figure 3In one embodiment of the utility model, the PHC pile quick-install mold 100 includes an upper mold 10, a lower mold 20 and a locking member 30. The upper mold 10 is hinged to the lower mold 20, and the two can be opened and closed. The upper mold 10 is provided with a plurality of first through holes 11. The locking member 30 is movably installed on the opening and closing end of the upper mold 10 and is provided with a plurality of second through holes 31. Each first through hole 11 is aligned with the second through hole 31. The lower mold 20 is provided with a connecting column 21 corresponding to each first through hole 11. The connecting column 21 passes through the first through hole 11 and the second through hole 31 and is partially exposed above the locking member 30. The locking member 30 is provided with a notch 32 corresponding to each second through hole 31. The notch 32 is connected to the corresponding second notch. The locking member is moved so that the first through hole 11 and the second through hole 31 are staggered, and the connecting column 21 enters the notch 32. The locking member 30 presses against the upper end of the connecting column 21 to lock the upper mold 10 and the lower mold 20.

[0026] In this embodiment, the upper mold 10 and the lower mold 20 are both special molds for PHC piles made of steel. The molds made of steel have a strong, durable structure and a long service life, and are suitable for large concrete pile manufacturing plants. The plurality of first through holes 11 are arranged in sequence along the length direction of the upper mold 10, and the plurality of connecting columns 21 are arranged along the length direction of the lower mold 20, and the connecting columns 21 are arranged perpendicularly to the opening and closing end of the lower mold 20.

[0027] Wherein, a limit block 22 is provided on the connecting column 21, and when the connecting column 21 enters the notch 32, the locking piece 30 abuts against the bottom of the limit block 22, the connecting column 21 is a cylindrical rod made of steel, the connecting column 21 is welded to the lower mold 20, and the limit block 22 is a truncated cone made of steel, which is welded to the connecting column 21, and when the upper mold 10 and the lower mold 20 are covered, the connecting column 21 passes through the first through hole 11 and the second through hole 31, so that the limit block 22 is exposed above the locking piece 30, and the bottom of the limit block 22 is spaced a certain distance from the locking piece 30; the width of the notch 32 is smaller than the diameter of the second through hole 31, and the outer diameter of the limit block 22 is consistent with the diameter of the second through hole 31, and when the connecting column 21 is stuck in the notch, the locking piece 30 can abut against the bottom of the limit block 22.

[0028] In one embodiment of the utility model, a boss 33 is provided around each notch 32 on the locking member 30. In an initial state, the boss 33 does not interfere with the connecting column 21. When the locking member 30 is moved to allow the connecting column 21 to enter the notch 32, the boss 33 abuts against the bottom of the limit block 22.

[0029] In this embodiment, the locking member 30 is a long strip made of steel, and the boss 33 is made of steel, which is connected to the locking member 30 by welding, and the welding point is polished to make the welding not too rough. The height of the boss 33 is greater than the distance between the bottom of the limit block 22 and the locking member 30. It can be understood that the height of the boss 33 is greater than the distance between the bottom of the limit block 22 and the locking piece 30. When the end of the locking piece 30 is hit with a hammer to move it so that the connecting column 21 enters the notch 32, there is an interference fit between the top of the boss 33 and the bottom of the connecting column 21. When the boss 33 is against the bottom of the limit block 22, the upper mold 10 and the lower mold 20 can be fitted more tightly. The boss 33 can be set to an inclined surface close to the second through hole 31. This can reduce the direct interference between the boss 33 and the limit block 22, reduce resistance, and allow the connecting column 21 to smoothly enter the notch 32.

[0030] In one embodiment of the utility model, a receiving groove 12 is provided on the opening and closing end of the upper mold 10, and sliding grooves 13 are provided on the opposite side walls of the receiving groove 12. A clamping platform 34 is provided on both sides of the locking member 30, and the clamping platform 34 is clamped in the sliding groove 13.

[0031] In this embodiment, the sliding groove 13 is arranged along the length direction of the upper mold 10, and the clamping platform 34 is clamped in the sliding groove 13, which can prevent the locking member 30 from being separated from the upper mold 10 when moving.

[0032] When in use: install the locking piece 33 into the receiving groove 12 of the upper mold 10, align the first through hole 11 with the second through hole 31, and then cover the upper mold 10 with the lower mold 20, the connecting column 21 passes through the first through hole 11 and the second through hole 31, and the limit block 22 is exposed above the locking piece 30. At this time, use an external tool such as a hammer to hit the end of the locking piece 30, the locking piece 30 moves, the first through hole 11 and the second through hole 31 are staggered, the connecting column 21 enters the notch 32, and the top of the boss 33 abuts against the bottom of the limit block 22, so that the upper mold 10 and the lower mold 20 fit more tightly, realizing rapid mold loading.

[0033] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
