Description

Technical Field

[0001] The invention relates to the technical field of prefabricated staircase moulds, in particular to a prefabricated staircase mould with a curing device. Background Art

[0002] As an important part of prefabricated buildings, prefabricated concrete stairs have been widely used in the construction industry in recent years. Compared with traditional cast-in-place stairs, prefabricated stairs have significant advantages such as high efficiency, fast construction speed, and high quality controllability. It is produced in a factory and transported to the construction site for hoisting and installation after completing all processes. It not only greatly shortens the on-site construction time, but also effectively reduces the project cost. Especially in high-rise buildings, the use of prefabricated stairs can significantly improve construction efficiency and ensure construction progress. The sliding support design at the lower end can also keep the escape route unobstructed during natural disasters such as earthquakes, thereby improving the safety of the building.

[0003] In order to solve the problems of low efficiency and high energy consumption in the traditional maintenance method of prefabricated stairs, a prefabricated staircase mold with a maintenance device came into being. This new mold adds a self-maintaining thermal pipeline system on the original basis, heats the concrete protective layer through hot water circulation, and realizes the rapid maintenance of prefabricated stairs. At the same time, a concrete insulation layer is added to the outside of the mold to improve the insulation effect and reduce heat energy loss. This maintenance device not only has a variety of energy options, but also realizes instant on-site maintenance, greatly improving construction efficiency and providing a strong guarantee for the large-scale production of prefabricated stairs.

[0004] Chinese patent CN216831493U discloses a prefabricated component maintenance mold, which relates to the technical field of maintenance molds. The prefabricated component maintenance mold includes a mold body of the prefabricated component and a maintenance component, and a receiving cavity is provided in the side template of the mold body; the maintenance component includes a heating component, and the heating component is arranged in the receiving cavity, and the input end and the output end of the heating component both extend out of the receiving cavity. The prefabricated component maintenance mold can realize the molding and maintenance of prefabricated components, and is easy to operate, occupies a small space, and has a low maintenance cost.

[0005] The above patent discloses a maintenance device for producing precast concrete stairs using a mold. The device heats up or cools down the inside of the mold cavity through a maintenance pipe. A temperature sensor is provided on the inner wall of the mold to control the temperature of the steam in the maintenance pipe, thereby controlling the overall maintenance temperature. However, due to the particularity of the shape of the staircase mold, one side is a straight plane and the other side is serrated, which means that the flat surface can achieve uniform temperature control through a general pipe, while the serrated surface is difficult to achieve because its irregular shape makes uniform heating more difficult. In addition, when the temperature is too high and the steam temperature in the maintenance pipe needs to be controlled to cool it down, the process is relatively slow because the steam in the pipe flows in one direction and needs to be cooled down through one end of the controller before entering the pipe. This makes it impossible to cool down quickly in an emergency. Summary of the invention

[0017] The present invention provides a prefabricated staircase mold with a curing device. It has the following beneficial effects:

[0018] 1. The present invention sets a membrane cavity, a heating groove, a cooling groove and a serrated heat transfer plate, and injects heating steam into the interior of the heating groove. The internal air pressure of the heating groove increases, and the serrated heat transfer plate is pushed, so that the serrated heat transfer plate is attached to the inner wall of the second side mold, so that the serrated surface of the stair concrete is heated evenly.

When heating is needed again, the first solenoid valve is closed and the second solenoid valve is opened. The heating tank re-injects heating steam into the interior of the heating groove and squeezes the serrated heat transfer plate at the same time, so that the serrated heat transfer plate is re-attached to the side wall. Moreover, the coolant inside the cooling groove is all injected into the interior of the heating tank under the action of the second one-way valve for reheating. On the one hand, it realizes the recovery of the coolant, which is recycled into the heating tank for reheating to provide a steam source for the subsequent curing process. On the other hand, it realizes the rapid recovery of the coolant and the recycling of the curing liquid.

[0020] 3. The present invention sets a temperature sensor, which is connected to the heating tank and the cooling tank. The temperature sensor sets the curing process heating curve in advance, and can take heating and cooling measures according to the actual temperature during the curing process, thereby further allowing the entire curing process to be cured according to the curing process heating curve.

[0021] 4. The present invention is provided with rollers and guide rails, and a hydraulic mold opening and closing system is arranged inside. The hydraulic mold opening and closing system is a prior art, and its functional principle is to push the mold to open and close the mold by the oil cylinder, that is, the separation and closing of the first side mold and the second side mold. The worker only needs to operate the remote control to realize automatic mold opening and closing, and the process is smooth and reliable.

[0022] 5. The present invention forms a group mold for stairs by setting up multiple first side molds and second side molds. The group molds are suitable for producing stair components of the same specifications that need to be produced in large quantities. Secondly, the group molds can give full play to the utilization rate of the molds, greatly reduce the site area, improve production efficiency, and reduce the consumption of time, space, material transportation, labor, etc. in the production process, thereby reducing costs.
