Description

Technical Field

[0001] The invention relates to the technical field of prefabricated concrete columns, and in particular to a detachable template structure for manufacturing prefabricated columns. Background Art

[0002] In actual construction projects and other scenarios, concrete pipe columns have a large number of applications. In the actual production process of concrete pipe columns, centrifuges are usually used for centrifugal molding. A steel cage is placed in the template and then filled with concrete. The template is then closed and the mold is placed in a special centrifuge for pipe piles to drive the template to rotate. Centrifugal force is used to mix and flatten the concrete inside the mold. The current prefabricated columns are made with detachable templates, and the coaxial accuracy between the internal steel cage and the plate is poor. The strength effect of the pipe column is reduced after forming, and it is not convenient to perform interference-free magnetic positioning. At the same time, the centrifugal molding method has poor fit between the concrete gravel and the steel bars, and it is easy to produce hollow bubbles. It is also easy for moisture to be concentrated in the outer diameter part due to centrifugal molding, and the internal moisture uniformity is poor, which can easily cause cracks after subsequent steam heating and curing. Therefore, the present application provides a detachable template structure for prefabricated columns to meet the needs. Summary of the invention

By adopting the provided adapter sliding member 4 and utilizing its own structure, it is possible to control the six main bars 202 and the externally welded stirrups by means of magnetic attraction, and utilize the magnetic attraction method to improve the fitting and embedding effect of the main bars 202 and the stirrups on the concrete. The magnetic attraction structure is utilized to control the main bars 202 and the stirrups to achieve a small shaking, and during the shaking process, it can better play the role of stirring. The main reinforcement 202 and stirrups are tightly attached to the concrete, and hollow bubbles are eliminated. The use is simpler. The control can be realized during the centrifugal forming of the concrete of the structure. The magnetic control rod 501 of the mechanism is pulled by the gravity of the counterweight block 503. At this time, the magnetic control rod 501 is no longer coaxial with the main reinforcement 202 and the stirrups. During the centrifugal rotation, the main reinforcement 202 and stirrups near the stirrup traction electromagnet 504 will shake under the action of magnetic attraction, so as to achieve better adhesion in the concrete and eliminate hollow bubbles. ;

[0043] like Figure 3 and Figures 7 to 9 As shown, the magnetic control component 5 also includes three stirrup traction electromagnets 504 fixedly embedded on the outside of the magnetic control rod 501; the stirrup traction electromagnets 504 are used to electromagnetically attract the six main bars 202 and the stirrups welded on the six main bars 202; the magnetic control rod 501 is a hollow structure, and three spraying slots 5011 are opened on the magnetic control rod 501. The magnetic control component 5 adopted in this structure can perform coaxial positioning work on the main bars 202 and the stirrups at the same time, and can limit the positions of the main bars 202 and the stirrups, effectively ensuring the coaxiality of the main bars 202 and the stirrups with the inner walls of the two forming templates 101, and can effectively improve the overall quality of the concrete pipe column after forming, so that the main bars 202 and the stirrups are completely surrounded inside the concrete column, reducing oxidation and rusting.

[0044] The working principle provided by the present invention is that after the concrete is filled inside the two forming templates 101, after passing through the bolt and nut assembly joint die, the two forming templates 101 can be placed in the pipe pile centrifuge, the centrifugal protrusions 102 correspond to the rollers of the pipe pile centrifuge, and the two forming baffles 201 are installed on the outside of the two forming templates 101 by bolts, and the corresponding main reinforcement 202 and stirrups pass through the two forming templates 101. Then, the magnetic control rod 501 is inserted into the sliding adapter column 401, and the mounting nut 502 is screwed in for limiting. As the two forming templates 101 are driven to rotate centrifugally, the magnetic control rod 501 of the mechanism is pulled by the gravity of the counterweight block 503. Under the action of gravity, the magnetic control rod 501 drives the sliding adapter column 401 to slide downward on the sleeve shell 302. At the same time, even if the main reinforcement 202 and the stirrups are centrifugally driven to rotate, the sliding adapter column 401 is still pressed down in the sleeve shell 302. At this time, the magnetic control rod 501 is no longer coaxial with the main reinforcement 202 and the stirrups. By starting the stirrup traction electromagnet 504, under the suction of the stirrup traction electromagnet 504, the main reinforcement 202 and the stirrups near the stirrup traction electromagnet 504 during the centrifugal rotation will shake under the action of magnetic attraction, so as to achieve better adhesion in the concrete and eliminate hollowing, and the structure can run smoothly. Reasonable, improve the connectivity between steel bars and concrete after forming, under the drive of the pipe pile centrifuge, the forming template 101 rotates at a high speed, and the water in the concrete inside the forming template 101 will be centrifugally thrown out through the centrifugal drainage hole 1011 under the action of centrifugal force, and will not be retained between the outside of the concrete pipe column and the inside of the forming template 101. At the same time, the splash-proof baffle 103 is used to prevent splashing, and the water inside the water storage box 603 is sucked by the water pump 602, and the water can be pumped into the water spray rod 601 for spraying. The water will be sprayed to the inside of the concrete column and diffuse outward with the centrifugal action, thereby improving the humidification uniformity. After the gravity-pulling magnetic control rod 501 eccentrically controls the main reinforcement 202 and the stirrups to shake, the three positioning electromagnets 303 are energized to generate the same adsorption force on the three positioning iron blocks 403. At this time, under the magnetic attraction of the three positioning electromagnets 303, the sliding adapter column 401 will rise again to achieve concentricity with the sleeve shell 302, that is, the two forming templates 101. At this time, under the magnetic attraction of the three stirrup traction electromagnets 504, the main reinforcement 202 and the stirrups will be adsorbed and concentric with the two forming templates 101, ensuring the molding position positioning accuracy of the main reinforcement 202 and the stirrups; open the closing cover 604 to add water to the water storage box 603.

[0045] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
