Description

Technical Field

[0001] This utility model belongs to the field of concrete pole production technology, specifically relating to a concrete pole casting mold. Background Technology

[0002] Electric poles are rod-shaped structures that support overhead power lines; also known as utility poles, they are an important component of infrastructure construction for power supply, communications, and other purposes. They play a crucial role in the upgrading of urban and rural power grids, as well as in the installation of various overhead power lines and communication cables.

[0003] The most widely used type of utility pole is the concrete pole. Concrete poles are usually cast using pole molds. The pole mold is a hollow cylindrical structure composed of two hollow semi-cylinders. The pre-made pole steel reinforcement skeleton is placed in the lower mold, and then concrete is poured into the lower mold. After the concrete is poured full, the upper mold is fixed together with the lower mold. Then, centrifugation is performed to make the concrete in the pole mold denser. Finally, steam curing is carried out to complete the casting and production of the concrete pole.

[0004] However, the current method of connecting the upper and lower molds of the utility pole is to hinge bolts along the edge of the lower mold and corresponding connection holes on the edge of the upper mold. When fixing the upper and lower molds, the bolts are inserted into the connection holes and then the nuts are tightened for fixation. During the pouring process, concrete easily clogs the bolt hinge connection of the lower mold, which is difficult to clean and causes inconvenience during connection. At the same time, when the upper and lower molds are closed, the poured concrete easily overflows from the mold connection edge and clogs the connection hole of the upper mold. The inconvenience of connection also causes the mold to close loosely, resulting in material leakage and waste of materials. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model designs a concrete pole casting mold to avoid the blockage caused by concrete, facilitate the closure of the mold connection, and prevent concrete overflow when the mold is closed, thereby reducing material waste.

[0006] This utility model discloses a concrete pole casting mold, comprising a separate upper mold and a lower mold, both of which are hollow semi-cylindrical in shape, forming a hollow cylinder when closed. The outer surfaces of the upper and lower molds are provided with reinforcing ribs and several positioning rings. Several upper connecting plates are equidistantly arranged along both sides of the upper mold, and connecting holes are provided on the upper connecting plates. Several lower connecting plates are arranged along both sides of the lower mold corresponding to the upper connecting plates. Threaded holes are provided on the outer walls of the lower connecting plates, and bolt assemblies are connected outwardly within the threaded holes. The bolt assemblies include connecting columns connected to the threaded holes, hinge clamps connected to the connecting columns, and locking bolt ends hinged within the hinge clamps. Nuts are threaded onto the locking bolts. A shielding wing plate is also provided at the top of the lower connecting plate, with a downward-sloping surface along the outer edge of the shielding wing plate.

[0007] The upper mold has a snap-fit ​​groove on the inner side of its bottom end face, which engages with a snap-fit ​​block on the inner side of the top end face of the lower mold.

[0008] The reinforcing ribs include transverse reinforcing ribs arranged along the length of the upper and lower molds and annular reinforcing ribs arranged around the circumference of the upper and lower molds.

[0009] The positioning rings are arranged around the circumference of the upper and lower molds, and several are equidistantly arranged from one end to the other along the length of the upper and lower molds. In the side view of the upper and lower molds, the diameter of the positioning rings completely covers the outside of the upper and lower molds.

[0010] The upper and lower molds are also welded with lifting rings on their outer surfaces.

[0011] The beneficial effects of this utility model are:

[0012] Compared with the prior art, the concrete pole casting mold of this utility model has an upper connecting plate with connecting holes on both sides of the upper mold, and a lower connecting plate corresponding to the upper connecting plate on both sides of the lower mold. Bolt assemblies are threaded onto the outer wall of the lower connecting plate to connect the upper and lower connecting plates, thus connecting the upper and lower molds. The connection between the upper and lower molds extends outward from the current mold edge. A shielding wing plate is provided at the top of the lower connecting plate, with a downward slope on its outer edge. When concrete is poured into the lower mold, the shielding wing plate blocks the threaded holes on the outer wall of the lower connecting plate, allowing the concrete to fall along the slope of the shielding wing plate, preventing concrete from clogging the threaded holes and thus avoiding obstruction of the connection between the upper and lower connecting plates. Simultaneously, a snap-fit ​​groove is provided on the inner side of the bottom end face of the upper mold, which engages with a snap-fit ​​block provided on the inner side of the top end face of the lower mold. This design prevents concrete from overflowing from the gap between the upper and lower molds when the molds are closed, resulting in a tighter closure and reducing material waste.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1

[0022] To prevent concrete blockage during the pouring of concrete poles using molds, and to facilitate the closing and connection of the upper and lower molds while avoiding concrete overflow when the molds are closed, thus reducing material waste, please refer to [reference needed]. Figures 1 to 4 As shown in this embodiment, a concrete pole casting mold is proposed, including an upper mold 1 and a lower mold 2 that are separated from each other. The upper mold 1 and the lower mold 2 are hollow semi-cylindrical in shape, which are closed to form a hollow cylinder, constituting the casting space of the concrete pole. The outer surfaces of the upper mold 1 and the lower mold 2 are provided with reinforcing ribs to improve the strength of the mold. The reinforcing ribs include transverse reinforcing ribs 3 arranged along the length direction of the upper mold 1 and the lower mold 2 and annular reinforcing ribs 4 arranged around the circumference of the upper mold 1 and the lower mold 2.

[0023] Several positioning rings 5 ​​are also provided on the outer surfaces of the upper mold 1 and the lower mold 2. The positioning rings 5 ​​are arranged around the circumference of the upper mold 1 and the lower mold 2, and are equidistantly arranged from one end to the other along the length of the upper mold 1 and the lower mold 2. In a side view of the upper mold 1 and the lower mold 2 from one end, as shown... Figure 2 As shown, the diameter of the positioning ring 5 completely covers the outside of the upper mold 1 and the lower mold 2. The positioning ring 5 is used to connect to the centrifuge device for rotating and centrifuging the molds.

[0024] Several upper connecting plates 6 are equidistantly arranged on both sides of the upper mold 1. Connecting holes 601 are opened on the upper connecting plates 6. Several lower connecting plates 7 are arranged on both sides of the lower mold 2 corresponding to the upper connecting plates 6. The length of the lower connecting plates 7 extending beyond the edge of the lower mold 2 is less than the length of the upper connecting plates 6 extending beyond the edge of the upper mold 1. Threaded holes 702 are opened on the outer wall of the lower connecting plates 7. Bolt assemblies 8 are connected outward from the threaded holes 702. The bolt assembly 8 includes a connecting post 801 connected to the threaded holes 702. A hinge clamp 802 is connected to the connecting post 801. The end of a locking bolt 803 is hinged to the hinge clamp 802. A nut 804 is threaded onto the locking bolt 803. The connection part between the upper mold 1 and the lower mold 2 extends outward from the current mold edge. When the upper mold 1 and the lower mold 2 are closed, the locking bolt 803 is rotated upward and locked into the connecting hole 601, so that the locking bolt 803 is in an upward vertical position. Then, the nut 804 is tightened to fix it, thereby fixing the upper mold 1 and the lower mold 2.

[0025] The lower connecting plate 7 is also provided with a shielding wing plate 701 at the top, and the outer edge of the shielding wing plate 701 is provided with a downward slope. During the process of filling the lower mold 2 with concrete, concrete will inevitably fall onto the top end face of the lower mold 2. The shielding wing plate 701 can block the concrete falling outside the lower mold 2, so that the concrete falls down along the slope of the edge of the shielding wing plate 701, avoiding concrete from blocking and sealing the threaded hole 702. When closing the mold, it is only necessary to simply clean the residual concrete on the top end face of the lower mold 2.

[0026] A snap-fit ​​groove 101 is provided on the inner side of the bottom end face of the upper mold 1, which engages with a snap-fit ​​block 201 provided on the inner side of the top end face of the lower mold 2. When the mold is closed, the snap-fit ​​block 201 and the snap-fit ​​groove 101 combine to block the concrete inside the mold, preventing the concrete from overflowing from the gap between the upper mold 1 and the lower mold 2. This makes the closed connection between the upper mold 1 and the lower mold 2 tighter and reduces material waste.

[0027] To facilitate the hoisting and movement of the upper mold 1 and the lower mold 2, lifting rings 9 are welded to the outer surfaces of the upper mold 1 and the lower mold 2.

[0028] The specific steps for using this concrete pole casting mold are as follows:

[0029] First, the hoisting device is connected to the lifting ring 9 of the lower mold 2. After hoisting to the production station, the pre-made pole steel reinforcement skeleton is placed in the lower mold 2. Then, concrete is poured into the lower mold 2. During the pouring process, the shielding wing plate 701 connected to the lower connecting plate 7 shields the falling concrete, preventing the concrete from covering and blocking the threaded hole 702 on the outer wall of the lower connecting plate 7. After the concrete is poured, the top end face of the lower mold 2 is cleaned. Then, the bolt assembly 8 is connected to the threaded hole 702. Then, the upper mold 1 is installed. During the installation process, the snap-fit ​​groove 101 and the snap-fit ​​block 201 are installed in correspondence. The snap-fit ​​block 201 and the snap-fit ​​groove 101 are combined to achieve installation and positioning, and also block the concrete inside the mold, preventing the concrete from overflowing from the connection part and avoiding material waste. After the upper mold 1 and the lower mold 2 are installed, the locking bolt 803 is rotated upward and locked into the connecting hole 601, so that the locking bolt 803 is in an upward vertical position. Then the nut 804 is tightened to fix it, thereby fixing and locking the upper mold 1 and the lower mold 2. Finally, the positioning ring 5 is installed with the centrifugal device to perform centrifugal molding of the concrete pole.

These preferred embodiments do not describe all details exhaustively, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
