Description
Technical Field
The invention relates to the technical field of round hole plate manufacturing processes, in particular to a long-direction stretching steel die prestress production process.
Background
The prestressed concrete round hole plate is a prefabricated production mode, each plate is independently tensioned and independently poured in the current production process, the process is complicated, the prestressed tensioning is uneven, and the efficiency is low, so that the quality is unstable, and the labor cost is high.
Disclosure of Invention
Compared with the independent prestressed reinforcement tensioning mode of each bottom die, the prestressed reinforcement tensioning operation process and the length of a prestressed reinforcement tensioning section are greatly reduced, so that the working efficiency is improved, and the material cost of prestressed reinforcements is saved.
In order to achieve the purpose, the invention provides the following technical scheme: a long-direction tension steel die prestress production process comprises the following steps:
step one, arranging a plurality of bottom moulds with the same width along the length direction to form a production queue;
secondly, releasing prestressed reinforcements according to the total length of the generation queue;
step three, performing long-direction tensioning on the prestressed reinforcement through an anchoring part;
step four, performing concrete pouring on each bottom die of the production queue;
and step five, after the concrete is solidified and cured to the relaxation strength, uniformly relaxing the prestressed reinforcement.
Preferably, in the step one, the total length of the production queue is 9 to 300 meters;
preferably, 0.3 m of stretching length is reserved at two ends of the prestressed reinforcement in the second step.
Preferably, the number of the bottom molds is 2 to 40.
The invention has the beneficial effects that: the using amount of prestressed reinforcements is reduced, and the using amount of the prestressed reinforcements is effectively saved by 10-20%. Because the independent tensioning of each plate is improved into the queue unified tensioning, the working time required by tensioning is saved, the production efficiency is greatly improved, and the labor cost is saved. Compared with independent tensioning of each plate, uniform tensioning avoids tensioning errors, ensures product quality and is more stable. Concrete is uniformly poured, the stability of the quality of the concrete is guaranteed, and the product quality is effectively improved.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts.
FIG. 1 is a schematic diagram of an application of the present invention.
Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
According to the figure 1, the process for producing the prestress of the long-direction tension steel die comprises the following steps:
step one, arranging a plurality of bottom moulds 1 with the same width along the length direction to form a production queue, wherein the total length of the production queue is 9-300 meters, and the number of the bottom moulds 1 is 2-40;
step two, placing the prestressed reinforcement 2 according to the total length of the generation queue, reserving 0.3 meter of stretching length at two ends of the prestressed reinforcement 2, and tensioning through the tension bearing beam 3;
step three, performing long-direction tensioning on the prestressed reinforcement 2 through an anchoring part;
step four, performing concrete pouring on each bottom die 1 of the production queue;
and step five, uniformly releasing and tensioning the prestressed reinforcement 2 after the concrete is solidified and cured to the releasing and tensioning strength.
In the above arrangement, the prestressed reinforcement 2 is tensioned in the long direction at one time, for example, by adopting the above scheme, in the process of simultaneously manufacturing 20 plates, the requirement of stretching 20 plates can be met only by reserving a group of long clamping lengths of the prestressed reinforcement 2, and compared with the original construction method in which each plate needs to be tensioned independently, that is, the clamping length of the prestressed reinforcement 2 needs to be reserved for each prestressed reinforcement 2 of each plate, the construction method can effectively save the use amount of the prestressed reinforcement 2.
Because it is a plurality of die blocks 1 adopt a set of prestressing steel 2 jointly to carry out the tension, consequently removed each end and reduced 2 quantity of prestressing steel: in the original construction method, each plate needs to be tensioned independently, each prestressed reinforcement 2 of each plate needs to be reserved with the tensioning working length of 300mm, the new construction method adopts one-time tensioning in the longitudinal direction, only one tensioning working length of 300mm needs to be reserved for 20 plates, and the using amount of the prestressed reinforcement 2 is effectively saved by 10% -20%.
Because the independent tensioning of each plate is improved into the unified tensioning of 20 plates, the working time required by tensioning is saved, the production efficiency is greatly improved, and the labor cost is saved.
Compared with independent tensioning of each plate, uniform tensioning avoids tensioning errors, ensures product quality and is more stable.
Concrete is uniformly poured, the stability of the quality of the concrete is guaranteed, and the product quality is effectively improved.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
