Channel plate mold and method for manufacturing channel plate by means of channel plate mold

Abstract

The invention relates to the field of manufacturing of building prefabricated pieces and provides a channel plate mold. The channel plate mold comprises a stress system and a forming system. The forming system is placed in the stress system. A prestressed steel bar penetrates through the forming system to be connected to the stress system. The forming system is separated from the stress system. The acting force generated through contraction after the prestressed steel bar is tensioned is conducted to the stress system. The channel plate mold has the effects that the number of times of mold transferring is increased, the service life is prolonged, and the overall weight of the mold is reduced. The invention further provides a method for manufacturing a channel plate by means of the channel plate mold. The method for manufacturing the channel plate by means of the channel plate mold comprises the steps that S1, an internal mold underframe is provided; S2, a core mold body is provided and fixed on the internal mold underframe, the core mold body comprises a movable part and a fixed part, and the movable part of the core mold body is fixed through a limiting bolt; and S3, a pair of end mold bodies and a pair of side mold bodies are provided, the end mold bodies and the side mold bodies are all fixed on the internal mold underframe, and a channel storage space used for storing concrete can be formed by closing the pair of end mold bodies and the pair of side mold bodies.

Description

【Technical field】 [0001] The invention relates to a grooved plate mold, in particular to a grooved plate mold with long service life and many turnover times and a method for making a grooved plate by using the grooved plate mold. 【Background technique】 [0002] At present, the channel plate is more and more widely used in the building structure, but the traditional channel plate mold is bulky, the amount of steel is large, the cost is high, and it is easy to deform. The channel plate is easy to crack during the stretching process and is not suitable for production. Channel plate with large span and large prestress. In the construction process of traditional channel plate molds to produce channel plates, the labor intensity is high, the production cost is high, the mold is easily deformed, resulting in deviations in component forming, and the phenomenon of wasting turnover materials and raw materials during construction is serious.

[0002] At present, the channel plate is more and more widely used in the building structure, but the traditional channel plate mold is bulky, the amount of steel is large, the cost is high, and it is easy to deform. The channel plate is easy to crack during the stretching process and is not suitable for production. Channel plate with large span and large prestress

In the construction process of the traditional grooved plate mold to produce the grooved plate, the labor intensity is high, the production cost is high, the mold is easily deformed, resulting in deviations in the component forming, and the waste of turnover materials and raw materials in the construction is serious.

[0003] Structurally, the traditional channel plate mold does not separate the stress system and the forming system. When the prestressed steel bar is stretched, the force generated by the shrinkage of the prestressed steel bar will directly act on the end mold and side mold. When manufacturing the mould, it is necessary to consider both the force and the molding of the mould, resulting in problems such as bulky mould, large amount of steel, and high difficulty in construction; The concrete member is deformed under compression, resulting in a large mutual extrusion between the channel plate member and the steel mandrel, resulting in damage to the channel plate member or deformation of the mandrel
