Description

[Technical Field]

[0001] This invention mainly relates to a green and environmentally friendly concrete pole steel mold. [Background Technology]

[0002] The steel formwork for the utility pole is placed on the running wheel, and then steel bars and mixed concrete are added. The steel formwork is then covered and fixed with bolts. The running wheel is driven by a motor to rotate, which in turn causes the steel formwork to rotate. Under the centrifugal force of the rotation, a hollow cement utility pole is formed and gradually solidifies. To accelerate this solidification process, steam from the boiler can be used after the rotation process to promote the cement's structural transformation.

[0003] After the steel bars are inserted into the steel formwork of the concrete pole, the two steel formwork pieces need to be fixed. Most existing concrete pole steel formwork is fixed by multiple sets of fixing screws, which is cumbersome, time-consuming and labor-intensive, and has poor practicality. [Summary of the Invention]

[0004] To address at least one of the aforementioned problems, this invention proposes a novel structural solution. The green and environmentally friendly concrete pole steel formwork adopts the following technical solution:

[0005] A green and environmentally friendly concrete pole steel formwork includes an upper formwork base, a lower formwork base, a fastening rod, and a locking rod, with the left sides of the upper and lower formwork bases hinged together.

[0006] The lower mold base has a first mating part on its right side, the upper mold base has a second mating part on its right side, and a third mating part is located above the second mating part.

[0007] The first mating part is provided with a first inner groove, and the second mating part is provided with a second inner groove. The first inner groove and the second inner groove are connected. The end of the fastening rod is hinged to the first mating part, and the locking rod is sleeved on the top of the fastening rod so that the locking rod can rotate around the fastening rod.

[0008] The locking rod rotates into the first inner groove and the second inner groove, with the locking rod protruding outside the second inner groove; the third mating part is provided with a connecting hole, and the end of the locking rod is provided with a plug, which is inserted into the connecting hole when the locking rod is rotated.

[0009] The plug has tapered ends extending from its upper and lower ends. A crimping element is provided inside the connector hole. The crimping element is connected to the connector hole by a spring to make the crimping element elastic. The crimping element is pushed by the spring to keep in contact with the tapered end that enters the connector hole.

[0010] Preferably, both the end face of the crimping member and the end face of the tapered end are provided with anti-slip texture.

[0011] Preferably, the crimping members are respectively disposed at the upper and lower ends of the connection hole, and the crimping members are respectively disposed on both sides of the connection hole.

[0012] Preferably, the length of the fastening rod is greater than the total length of the first inner groove and the second inner groove.

[0013] Preferably, the first inner groove is provided on the edge of the first mating part, the first inner groove passes through the first mating part, and the first inner groove has an open side for the fastening rod to be rotatably inserted; the second inner groove is provided on the edge of the second mating part, the second inner groove passes through the second mating part, and the second inner groove has an open side for the fastening rod to be rotatably engaged.

[0014] Preferably, the first inner groove and the second inner groove are located on the same vertical line so that the fastening rod can be simultaneously rotated into the first inner groove and the second inner groove.

[0015] Preferably, the top of the fastening rod is provided with an end and a limiting block, the end of the locking rod is provided with a through hole for the fastening rod to pass through, and the locking rod is located between the end and the limiting block to limit the position of the locking rod.

[0016] The beneficial effects of this invention compared to the prior art are as follows:

[0017] This invention provides a green and environmentally friendly concrete pole steel formwork. The upper and lower formwork bases are fastened together by connecting a third mating part with a snap-fit ​​rod. Simultaneously, the plug abuts against the crimping member inside the connection hole. As the steel formwork rotates, the centrifugal force increases, causing the plug to tend to move towards the end of the connection hole. Because the plug is conical, the pressure on the crimping member connected to it also increases accordingly, strengthening friction and improving the connection strength between the snap-fit ​​rod and the third mating part. The faster the rotation, the better the connection strength. It has advantages such as simple structure, compact fit, and reasonable design; therefore, it is a product with superior technical and economic performance. [Attached Image Description]

[0024] In this invention, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0025] The following description, in conjunction with the accompanying drawings, further illustrates specific embodiments of the present invention, making the technical solution and its beneficial effects clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the invention.

[0026] The preferred embodiments provided by the present invention are as follows: Figures 1-5 As shown, a green and environmentally friendly concrete pole steel formwork includes an upper formwork base 1, a lower formwork base 2, a fastening rod 3, and a locking rod 4. The upper formwork base 1 and the lower formwork base 2 are hinged to each other on their left sides.

[0027] The lower mold base 2 has a first docking part 21 on its right side, the upper mold base 1 has a second docking part 11 on its right side, and a third docking part 12 is provided above the second docking part 11.

[0028] The first docking part 21 is provided with a first inner groove 22, and the second docking part 11 is provided with a second inner groove 13. The first inner groove 22 and the second inner groove 13 are connected. The end of the fastening rod 3 is hinged to the first docking part 21 through a shaft. The locking rod 4 is sleeved on the top of the fastening rod 3 so that the locking rod 4 can rotate around the fastening rod 3.

[0029] The fastening rod 3 is rotated into the first inner groove 22 and the second inner groove 13. The length of the fastening rod 3 is greater than the total length of the first inner groove 22 and the second inner groove 13, so that the locking rod 4 protrudes outside the second inner groove 13. The third mating part 12 is provided with a connecting hole 14. The end of the locking rod 4 is provided with a plug 41. The locking rod 4 is rotated to insert the plug 41 into the connecting hole 14. The access end of the plug 41 is provided with an arc 43 so that the plug can smoothly enter the connecting hole.

[0030] The top of the fastening rod 3 is provided with an end 32 and a limiting block 33. The end 32 and the limiting block 33 are spaced apart to reserve the position of the locking rod 4. The diameter of the end 32 is larger than the diameter of the fastening rod 3. The limiting block 33 is provided on the end face of the fastening rod 3. The end of the locking rod 4 is provided with a through hole for the fastening rod 3 to pass through. The locking rod 4 is provided between the end 32 and the limiting block 33 to restrict the position of the locking rod 4.

[0031] The plug 41 has tapered ends 42 extending from its upper and lower ends. A crimping member 15 is provided inside the receiving hole 14. The crimping member 15 is connected to the receiving hole 14 by a spring 16, so that the crimping member 15 is elastic. The crimping member 15 is pushed by the spring 16 to keep in contact with the tapered end 42 entering the receiving hole 14. Both the end face of the crimping member 15 and the end face of the tapered end 42 are provided with anti-slip texture to improve friction.

[0032] Crimping members 15 are respectively disposed at the upper and lower ends of the connector 14, and are also disposed on both sides of the connector 14 to correspondingly press the tapered ends 42 of the plug 41. A first inner groove 22 is disposed at the edge of the first mating portion 21, penetrating the first mating portion 21, and has an open side for the fastening rod 3 to be rotatably inserted. A second inner groove 13 is disposed at the edge of the second mating portion 11, penetrating the second mating portion 11, and has an open side for the fastening rod 3 to be rotatably engaged. The first inner groove 22 and the second inner groove 13 are located on the same vertical line so that the fastening rod 3 can be simultaneously rotatably engaged in both the first inner groove 22 and the second inner groove 13.

[0033] Operation Flow: After placing the reinforcing bars and mixed concrete into the steel molds (i.e., upper mold base 1 and lower mold base 2), cover the upper mold base 1 and lower mold base 2. Flip the fastening rod 3 of the first inner groove 22 so that the fastening rod 3 simultaneously connects to the first inner groove 22 and the second inner groove 13, and at this time, the locking rod 4 protrudes from the second inner groove 13. The plug 41 of the locking rod 4 is located on the same horizontal plane as the third connecting part 12. Rotate the locking rod 4 so that the connector is inserted into the connecting hole 14. The locking rod 4 is prevented from disengaging from the third connecting part by the crimping piece 15 connecting to the plug 41, thereby keeping the upper mold base 1 and lower mold base 2 connected. Furthermore, the running wheel drives the pole steel mold to rotate. The upper and lower ends of the plug 41 are conical. As the centrifugal force increases with the rotation of the steel mold, the plug 41 tends to move towards the end of the connection hole 14. Since the plug 41 is conical, the pressure on the crimping part 15 connected to the plug 41 will also increase accordingly, which strengthens the friction and improves the connection firmness between the locking rod 4 and the third docking part 12. The faster the rotation, the better the connection firmness.
