Description

Technical Field

[0001] This application relates to the field of cement pole production technology, and more specifically, to an integrated cement pole prefabrication mold. Background Technology

[0002] Cement poles are mainly composed of steel bars and concrete, hence they are also called reinforced concrete cement poles. They are the pillars for erecting circuits in circuit transmission and are formed by casting in precast molds.

[0003] The prior art publication CN222178201U provides an integrated cement pole prefabrication mold, specifically relating to the field of cement pole forming and processing technology. It includes an outer mold cylinder and a base at the bottom of the outer mold cylinder. The two ends of the outer mold cylinder are respectively bolted with a left end cap and a right end cap. An inner mold tube is provided inside the outer mold cylinder. The inner side of the left end cap is provided with a positioning boss with a certain taper that matches the inner hole of the inner mold tube. The surface of the right end cap is provided with a through hole that matches the outer diameter of the inner mold tube. A grouting pipe is provided on one side of the top of the outer mold cylinder, and an exhaust pipe is provided on one side of the bottom of the outer mold cylinder.

[0004] Although the existing technical solutions described above can achieve the relevant beneficial effects through their structure, they still have the following drawbacks:

[0005] Cement poles are typically structured with one end larger than the other. The larger end is connected to the ground during installation to increase the support area. Simple auxiliary formwork is insufficient for casting truncated concrete poles, and the concrete poles require a steel cage to increase strength. However, an inner and outer cylinder structure alone cannot position the steel cage, making it difficult to cast the poles successfully in one go.

[0006] Regarding the aforementioned related technologies, the inventor believes that cement poles are typically structures with one large end and one small end. When the large end is installed, it connects to the ground to increase the support area. Simple auxiliary molds are not suitable for casting truncated concrete poles. Furthermore, the strength of the cement pole needs to be increased by a steel cage. The structure of only an inner and outer cylinder cannot position the steel cage, making it difficult to cast successfully in one go.

[0007] In view of this, we propose an integrated precast mold for cement poles. Utility Model Content

[0008] 1. Technical problems to be solved

[0009] The purpose of this application is to provide an integrated precast concrete pole mold, which solves the technical problems in the background art where concrete poles are usually a structure with one large end and one small end. When the large end is installed, it is connected to the ground to increase the support area. It is difficult to cast a truncated concrete pole using a simple auxiliary mold cylinder. Furthermore, the concrete pole needs to be reinforced with a steel cage to increase its strength. However, the inner and outer cylinder structures cannot position the steel cage, making it difficult to cast the pole successfully in one go. This application achieves the desired technical effect.

[0010] 2. Technical Solution

[0011] This application provides an integrated precast mold for cement poles, comprising:

[0012] Fixture;

[0013] The outer cylinder is mounted on the fixing frame;

[0014] An inner cylinder is provided inside the outer cylinder;

[0015] A reinforcing cage is provided between the outer cylinder and the inner cylinder;

[0016] A bottom support is installed between the bottoms of the outer cylinder, the inner cylinder, and the reinforcing cage;

[0017] A positioning plate is installed between the top of the outer cylinder, the inner cylinder, and the reinforcing cage.

[0018] The above scheme uses an openable outer cylinder, a bottom support, and a positioning plate to position and clamp the inner cylinder and the reinforcing cage within the inner cavity of the outer cylinder. This allows cement to be poured from the top between the inner and outer cylinders. The cement encapsulates the reinforcing cage, and after shaping, it forms a cement rod that is larger at one end and smaller at the other. Then, the outer cylinder is opened, and the inner cylinder is pulled out to obtain a cement rod that has been formed in one piece.

[0019] Optionally, the outer cylinder includes a fixed cylinder and a movable cylinder. The fixed cylinder is fixedly installed on a fixed frame. Connecting plates are fixedly installed on both outer walls of the movable cylinder and the fixed cylinder. The connecting plates are bolted together. Both the fixed cylinder and the movable cylinder are semi-circular frustum bodies that are larger at the top and smaller at the bottom. The inner cylinder and the reinforcing cage are frustum structures coaxial with the fixed cylinder. Multiple vibrators are fixedly installed on the inner wall of the inner cylinder and the outer walls of the fixed cylinder and the movable cylinder.

[0020] With the above solution, the movable cylinder can be detachably installed from the fixed cylinder via the connecting plate, thus forming a frustum outer cylinder after installation. After opening, it is easy to remove the formed cement rod.

[0021] Optionally, the bottom support includes a support plate, which is bolted to the bottom of the fixed cylinder and the movable cylinder. A central column is fixedly installed in the middle of the support plate, and the central column is movably sleeved on the bottom of the inner cavity of the inner cylinder. A positioning ring is fixedly installed on the support plate, and the positioning ring is engaged with the bottom outer wall of the reinforcing cage.

[0022] With the above scheme, after the movable cylinder is connected to the fixed cylinder, the inner cylinder and the reinforcing cage are inserted from the top and then respectively engaged with the central column and the positioning ring. Finally, the support plate is bolted to the fixed cylinder and the movable cylinder, so as to achieve the purpose of sealing the bottom of the outer cylinder and supporting and positioning the inner cylinder and the reinforcing cage.

[0023] Optionally, the positioning plate includes an installation plate, with the tops of the fixed cylinder and the movable cylinder respectively connected to the two ends of the installation plate by bolts. A first inner ring and a second inner ring are fixedly installed at the bottom of the installation plate. The first inner ring is engaged with the top inner wall of the inner cylinder, and the second inner ring is engaged with the top inner wall of the reinforcing cage. The gap between the inner cylinder and the outer cylinder on both sides of the installation plate forms a pouring port.

[0024] With the above scheme, after the inner cylinder and the reinforcing cage are inserted, the mounting plate is attached to the top of the fixed cylinder and the movable cylinder and fixed with bolts, so that the first inner ring and the second inner ring are engaged with the inner cylinder and the reinforcing cage, achieving the purpose of limiting and fixing. In this way, the inner cylinder and the reinforcing cage are coaxially fixed with the outer cylinder, which facilitates the one-time casting of the cement rod.

[0025] 3. Beneficial effects

[0026] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0027] 1. In this application, after the movable cylinder is connected to the fixed cylinder, the inner cylinder and the reinforcing cage are inserted from the top and then respectively engaged with the central column and the positioning ring. Finally, the support plate is bolted to the fixed cylinder and the movable cylinder to achieve the purpose of sealing the bottom of the outer cylinder and supporting and positioning the inner cylinder and the reinforcing cage. After the inner cylinder and the reinforcing cage are inserted, the mounting plate is attached to the top of the fixed cylinder and the movable cylinder and fixed with bolts, so that the first inner ring and the second inner ring engage the inner cylinder and the reinforcing cage to achieve the purpose of limiting and fixing. In this way, the inner cylinder and the reinforcing cage are coaxially fixed with the outer cylinder, which facilitates the formation of a cement rod with one end larger than the other and the interior reinforced by the reinforcing cage in one pour.

Through the openable outer cylinder 2, the bottom support 5 and the positioning plate 6, the inner cylinder 3 and the reinforcing cage 4 are positioned and clamped in the inner cavity of the outer cylinder 2, thereby allowing cement to be poured from the top between the inner cylinder 3 and the outer cylinder 2. The cement encapsulates the reinforcing cage 4, and after shaping, a concrete pole with one end larger than the other is formed. Then, the outer cylinder 2 is opened and the inner cylinder 3 is pulled out to obtain a one-time formed concrete pole.
